Description

  The present invention relates to agriculture, horticulture, landscaping, and the like, and relates to a technique for efficiently supplying fertilizers, drugs, air, and the like into soil.

  In general, fertilizers, insecticides, herbicides, etc. for helping plants such as flowers, trees or lawns are marketed in bottles or bags in liquid, powder, granular or pellet form. . Consumers who have purchased such forms of pesticides use them by spraying them on the surface of soil, lawn, etc., sowing or mixing them with the soil.

  Some liquid fertilizers are contained in ampule containers, and those that are devised to cut the tip of the container and insert it near the root of the plant and gradually increase the effect are commercially available. However, solid fertilizers and insecticides are not effective in ampule containers, and therefore, the method of embedding and inserting the entire container into the soil is used.

For example, Patent Document 1 is an invention related to a method for replenishing liquid fertilizer, and a point-shaped tree replenisher having a plurality of through holes has been proposed, and liquid fertilizer can be replenished periodically. Patent Document 2 is a dual-structure soil case having a plurality of through-holes, in which a solid fertilizer is contained in the soil case and the fertilizer in the container is eluted into the soil together with water. Fertilize. And after all the fertilizers elute in the soil, the fertilizers can be replenished in the container. Moreover, patent document 3 is invention regarding the water supply method of a plant, and makes it possible to supply water to a deep root in the soil with a soil case having a plurality of through holes. In addition, after these soil cases are all embedded in the soil, they remain in the soil without being spoiled and can be replenished with internal fillers.

  However, since all cases for soil having such a structure remain in the soil, fertilizers such as fertilizers or medicinal ingredients such as herbicides (hereinafter referred to as “soil infiltrant”) are used in the same place each time. Will be supplied. However, there is a problem that even if the soil infiltration material is supplied to the same place every time, the effect obtained by the supply is weak. Further, when the soil case is embedded in a wide range, it is necessary to find the soil case embedded last time and to pack the soil infiltrating material into the found soil case, and this replenishment work is problematic. For example, if it is going to perform these operations in a vast site such as a golf course, a great deal of labor is required. Furthermore, if the soil to be embedded is covered with turf, etc., putting fertilizers into the soil case will vigorously grow the turf and hide the soil case. The task of finding out is just a pain. Furthermore, there is a problem that the case for soil left without replenishment of the penetrating material remains without being decomposed in the soil.

  In order to solve the above-mentioned problem, the first invention has a side wall that forms a soil infiltrant holding region, a through hole for allowing the soil infiltrant to permeate into the soil is formed in the side wall, and all or part of the material is formed.

  Embodiment 1

  (Concept of Embodiment 1) The soil embedding case of the present embodiment forms a soil infiltrant holding region for holding the soil infiltrant on the side wall, and has a through hole for allowing the soil infiltrant to penetrate into the side wall. The present invention relates to a soil embedding case made of a biodegradable resin.

  (Configuration of Embodiment 1) FIG. 1 shows an example of a soil embedding case according to this embodiment. As illustrated in FIG. 1, the soil embedding case (0100) of the present embodiment has a side wall (0102) that forms a soil infiltrant holding region (0101), and the soil infiltrant is placed on the side wall. A through-hole (0103) for penetrating into the resin is made, and all or part of the material is a biodegradable resin.

(Description of Configuration of Embodiment 1)
The “soil penetrant holding region” (0101) is a region for holding the soil penetrant. “Soil penetrating material” is a material to be supplied into the soil. Specifically, fertile ingredients such as fertilizers and medicinal ingredients such as herbicides and insect repellents are applicable. In addition, although a liquid thing can also be inject | poured into a soil osmosis | permeation material holding | maintenance area | region, in order to elute a soil osmosis | permeation material gradually in soil, it is desirable to throw in a solid thing. Moreover, even when nothing is put in the soil penetrant holding region, it is possible to send air into the soil. In this case, “air” corresponds to the soil permeation material. For example, if turf is growing in the soil where the soil embedding case is embedded, burying the soil embedding case that does not put anything in the soil penetrant holding area will pierce the soil where the lawn grows. The same effect as the work is obtained.

  “Sidewall” (0102) forms a soil infiltrant retention area. A through-hole (0103) is made in the side wall in order to allow the soil-penetrating material to penetrate into the soil. In addition, as long as the shape which a side wall forms can form a soil osmosis | permeation material holding | maintenance area | region, what kind of shape may be sufficient as it. FIG. 2 shows an example of the shape of the soil permeation material holding region formed by the side wall. As shown in FIG. 2, the shape formed by the side wall may be any shape such as a cylindrical shape (0201), a conical shape (0202), a rectangular parallelepiped shape (0203), or a pyramid shape (0204). Moreover, as shown in FIG. 3, a lid (0301) may be attached to the side wall, or an egg shape (0302) may be used. Any shape, size, interval, and quantity may be used for the through-holes formed in the side wall as long as the soil-penetrating material can penetrate into the soil. However, it is necessary to make the through hole smaller than the size of the soil infiltrating material.

  The material of the side wall is made of a biodegradable resin. A biodegradable resin is a resin that can be used in the same way as a normal resin product, and is finally decomposed mainly into water and carbon dioxide by natural microorganisms after use. In addition, as for a side wall, it is desirable that the whole consists of biodegradable resin. In this case, since the case for embedding the soil is completely decomposed after being embedded in the soil, no residue remains in the soil. However, other materials may be used for only a part of the side wall without using the biodegradable resin. For example, a part of the side wall may be formed of starchy material, or may be formed of fertilizer itself. Moreover, in order to accelerate | stimulate decomposition | disassembly of biodegradable resin, it is good also as a shape which gives a notch to a side wall as shown in FIG. 4, and a surface area becomes large.

  Even when the same biodegradable resin is used as the material of the sidewall, the period during which the soil embedding case remains in the soil changes by changing the thickness thereof. For example, if fertilizers and medicinal ingredients used as soil permeation materials are eluted slowly over a long period of time, the material of the side wall is made thicker (for example, 2 mm), and if it dissolves quickly in a short period of time By making the material of the side wall thin (for example, 0.5 mm), a soil embedding case that matches the soil infiltrating material can be produced.

  (Specific Example of Embodiment 1) A specific example of the soil embedding case of Embodiment 1 will be described below. In the soil embedding case in the present embodiment, Bionore 3020 (registered trademark) manufactured by Showa Polymer Co., Ltd. was used as the biodegradable resin, and the thickness was 1 mm. Fertilizer can be supplied by putting fertilizers and the like in such a soil embedding case and embedding it in the roots of flowers.

  As shown in FIG. 5, when water is supplied to the soil embedded with the soil embedding case by rain or watering, the soil infiltrating material of the soil embedding case is eluted into the moisture and penetrated through the side walls. The soil permeation material is supplied by the flow of moisture from the pores into the soil and the release of fertilizer components. Further, the side wall made of biodegradable resin is gradually decomposed into carbon dioxide, water and the like by microorganisms in the soil. For this reason, the decomposed biodegradable resin does not adversely affect the environment. Furthermore, when a soil embedding case is used, medicinal components and the like can be supplied in a pinpoint manner. Therefore, even when trying to control the weeds around the paddy field, since the herbicide is not sprayed, the air in the paddy field is not adversely affected.

  Even if you forget where you embed the soil-embedded case, remember that you embed the soil-embedded case because the soil-embedded case is decomposed in the soil. There is no need to be.

  (Simple explanation of the effect of Embodiment 1) As mentioned above, in the soil embedding case of this embodiment, since it decomposes | disassembles in soil, it does not remain in soil as it is, and it is for soil use Each time a multipurpose case is embedded, it can be embedded in a different place. In addition, it is not necessary to find the soil embedding case embedded last time or to supply the fertilizer to the found soil embedding case, and work efficiency can be improved. Therefore, there is an excellent effect that the soil infiltrating material can be efficiently supplied.

  << Embodiment 2 >>

  (Concept of Embodiment 2) The soil embedding case of the present embodiment is based on the soil embedding case of Embodiment 1, and further, the end on the side where the soil embedding case is embedded has a pointed shape, It is a technology related to a soil embedding case that improves the ease of embedding in soil.

  (Configuration of Embodiment 2) FIG. 6 shows an example of a soil embedding case according to this embodiment. As illustrated in FIG. 6, the soil embedding case (0600) of the present embodiment is based on the soil embedding case described in the first embodiment, and has a side wall (0602) with a through hole (0603). ), A soil penetrant holding region (0601) is formed. Since these configurations have been described in the first embodiment, a description thereof will be omitted. The soil embedding case of the present embodiment is further characterized in that the soil embedding end (0604) has a pointed shape.

  (Description of Configuration of Embodiment 2) “Soil embedded end” (0604) refers to an end portion on the side to be inserted into soil when a soil embedded case is embedded. A soil embedding case can be embedded in the soil by temporarily placing the soil embedding end shown in FIG. 6 on the surface of the soil and pressing the opposite end. By making this soil embedding end into a pointed shape, the resistance when embedding the soil embedding case in the soil is reduced, and the soil embedding end can be easily inserted.

  (Simple explanation of the effect of Embodiment 2) As mentioned above, in the soil embedding case of this embodiment, the soil embedding end has a pointed shape, so that it can be easily embedded in soil. The case can be inserted, and the working efficiency is further improved. Therefore, in addition to the effects described in the first embodiment, the soil permeation material can be further efficiently supplied.

  << Embodiment 3 >>

  (Concept of Embodiment 3) The soil embedding case of the present embodiment is based on the soil embedding case of Embodiment 1 or 2, and further, no through hole is formed at the tip of the soil embedding end. This is a technique relating to a soil embedding case in which the strength of the tip of the soil embedding end is improved.

  (Configuration of Embodiment 3) FIG. 7 shows an example of a soil embedding case according to this embodiment. As illustrated in FIG. 7, the soil embedding case (0700) of the present embodiment is based on the soil embedding case described in the second embodiment, and has a side wall (0702) with a through hole (0703). ), A soil penetrant holding region (0701) is formed, and the soil embedded end (0704) has a pointed shape. Since these configurations have been described in the first or second embodiment, description thereof will be omitted. The soil embedding case according to the present embodiment further includes a cylindrical portion (0705) formed of the side wall and a tip end portion (0706) forming a part of the soil embedding end. Is characterized in that no through hole is formed.

  (Description of Configuration of Embodiment 3) In the “tubular portion” (0705), a tubular soil infiltrant holding region is formed by the side wall, and the soil infiltrant is put in the formed hollow cylindrical portion. it can. Note that the cylindrical portion is not limited to the cylindrical shape illustrated in FIG. 7, and may be a rectangular tube shape or other shapes.

  The “tip portion” (0706) refers to an end portion including a peak-shaped top portion among the soil embedded ends. There is no through hole in the tip. When embedding the soil embedding case, the load is most applied to the tip portion, and therefore it is desirable that the tip portion is stronger than the cylindrical portion. Therefore, the strength can be made higher than that of the cylindrical portion by not making a through hole in the tip portion. Further, the strength can be further increased by making the tip portion solid. In this way, by increasing the strength of the tip, the soil embedding case can be easily embedded even in hard ground soil.

  (Simple explanation of the effect of Embodiment 3) As mentioned above, in the soil embedding case of this embodiment, it has the front-end | tip part by which the through-hole is not vacated, Therefore The strength is improved, and the working efficiency of the soil embedding case can be further improved. Therefore, in addition to the effects described in the first or second embodiment, the soil infiltrating material can be supplied more efficiently.

  << Embodiment 4 >>

  (Concept of Embodiment 4) The soil embedding case of this embodiment is based on the soil embedding case of Embodiments 1 to 3, and the soil embedding end has a plurality of squeezed shapes. The present invention relates to a technology that facilitates embedding a case for soil in soil.

  (Configuration of Embodiment 4) FIG. 8 shows an example of a soil embedding case according to this embodiment. As illustrated in FIG. 8, the soil embedding case (0800) of the present embodiment is based on the soil embedding case described in the second embodiment, and has a side wall (0802) with a through hole (0803). ), A soil penetrant holding region (0801) is formed, and the soil embedded end (0804) has a pointed shape. Further, when adding the function of the third embodiment, a corresponding configuration is added. Since these configurations have been described in the first to third embodiments, a description thereof will be omitted. The soil embedding case according to the present embodiment is further characterized in that the soil embedding end (0804) has a multi-stage drawing shape toward the embedding apex (0805).

  (Description of Configuration of Embodiment 4) “Embedded vertex” (0805) refers to the apex of the pointed shape of the soil embedded end. As shown in FIG. 8, the soil embedding case according to the present embodiment has a plurality of narrowed shapes with the soil embedding end directed toward the embedding apex.

  “Drawing shape” refers to a shape in which the soil embedded edge gradually converges toward the embedded vertex of the soil embedded edge. “The soil embedded end converges” means that when the cross-sectional view in the AA cross section shown in FIG. 8 is FIG. 9, the radius R of the cylindrical body (0901) shown in FIG. Means that R = 0.

  As shown in FIG. 10, “multi-stage aperture shape” means that the aperture shape at the soil embedding end is a shape that forms a plurality of levels. In FIG. 10, the soil embedding end has a first-stage (1001), second-stage (1002), and third-stage (1003) drawn shape toward the embedding apex.

  Next, the case where the aperture shape as shown in FIG. 8 is a two-stage aperture shape will be described in detail. In this case, the aperture shape far from the embedded vertex (0805) is the first aperture (0806), and the aperture shape near the embedded vertex is the second aperture (0807). Each of these aperture shapes can be specified in the front projection view of the soil embedding case. FIG. 11 shows a front projection of the soil embedding case of FIG. In FIG. 11, when the outer shape of the first stage aperture (1101) is extended to the embedding apex side and the intersection is P, the apex angle at P of the first stage aperture is α. Further, the angle at the apex angle where the outer shape of the second stage aperture (1102) includes the embedded vertex (1103) is β. Furthermore, the difference between the apex angle β of the second stage stop and the apex angle α of the first stage stop is γ.

  At this time, it is desirable that the apex angle α formed by the first stage aperture is 15 to 35 degrees. Further, it is desirable that the apex angle β formed by the second stage aperture is 20 degrees to 45 degrees. Further, the difference γ between the apex angle β of the second stage aperture and the apex angle α of the first stage aperture is preferably 5 degrees or more. Specific numerical values are preferably α = 15.78 degrees, β = 40 degrees, and γ = 24.22 degrees, but are not limited to these angles as long as the above-described conditions are satisfied. In this way, increasing the angle of the aperture shape near the embedding vertex increases the strength near the embedding apex where the pressing force is applied, and reducing the angle of the aperture shape far from the embedding vertex reduces the insertion into the soil. Can be easy.

  (Simple explanation of the effect of Embodiment 4) As mentioned above, in the soil embedding case of this embodiment, by attaching a multi-stage drawing shape to the soil embedding end, the soil embedding case can be applied to the soil. The insertion can be facilitated and the efficiency of the embedding work can be further improved. Therefore, the soil permeation material can be supplied more efficiently.

  (Configuration of Embodiment 5) FIG. 12 shows an example of a soil embedding case according to this embodiment. As illustrated in FIG. 12, the soil embedding case (1200) of the present embodiment is based on the soil embedding case described in the second embodiment, and has a side wall (1202) with a through hole (1203). ) To form a soil penetrant holding region (1201), and the soil embedded end (1204) has a pointed shape. Moreover, when adding the function of Embodiment 3 or 4, a corresponding structure is added. Since these configurations have been described in the first to fourth embodiments, a description thereof will be omitted. And the soil embedding case of this embodiment further has a root cutting fin (1205) on the side wall (1202).

  (Description of Configuration of Embodiment 5) A “root cutting fin” (1205) is a plate-like body made of a biodegradable resin, and is provided on a side wall. As shown in FIG. 13, which is a cross section taken along the line AA of FIG. 12, the root cutting fins may be provided with four fins (1301) on the side wall, or two, three, five or more. The root cutting fin may have an angle with respect to the cross section of the side wall or may be only one piece. However, in the soil embedding case, the soil embedding case is perpendicular to the soil. It is desirable to provide a plurality of root cutting fins perpendicular to the cross section of the side wall. Further, it is desirable that the tip of the root cutting fin has a pointed shape as shown in FIG. 13 to facilitate root cutting.

  With the root cutting fin, it is possible to perform root cutting of the plant growing in the place where the soil embedding case is embedded in the soil. For example, if lawn is growing in the soil where the soil embedding case is embedded, embedding the soil embedding case with root cutting fins, Supply work or drilling work can be performed simultaneously. Further, providing the root cutting fins also reinforces the side walls.

  As shown in FIGS. 14 (b) and 14 (c), the root cutting fins may be provided with a rectangular plate-like body on the side wall, but are embedded in order to reduce resistance when the soil embedding case is embedded. As shown in FIG. 14A, it is desirable that the apex-side end be continuous with the pointed shape of the soil-embedded end.

It consists of.

  (Description of Configuration of Embodiment 6) A “soil embedding case driving machine” (1600) is a machine capable of driving a soil embedding case into soil. The soil embedding case used in the soil embedding case driving machine may use any of the soil embedding cases described in the first to fifth embodiments. As shown in the conceptual diagram of FIG. 15, the soil embedding case driving machine may be driven by human power or may have the same configuration and be driven electrically. The soil embedding case driving machine includes a “soil embedding case holding and dropping unit” (1701), a “soil embedding case standby unit” (1702), and a “pressure rod (1703)”. As shown in FIG. 16, these may be arranged side by side and driven by a plurality of soil embedding cases at the same time.

  The “soil embedding case holding and dropping unit” (1701) is configured to supply the soil embedding case standby unit (1702) to the soil embedding case. As shown in FIG. 18, the soil embedding case holding / falling section (1801) includes a “soil embedding case holding means” (1804) and a soil embedding case dropping opening (1805).

  "Soil embedding case holding means" (1804) is means for holding a plurality of soil embedding cases according to any one of the first to fifth embodiments in series. The soil embedding case used in the present embodiment is preferably used with a lid in order to connect a plurality of cases vertically. Further, in a state where the soil embedding case is held by the soil embedding case holding means, it is desirable that the soil permeation material holding region of the soil embedding case is filled with a soil permeation material. However, when supplying air into the soil, the soil embedding case is held by the soil embedding case holding means in a state where the soil infiltrating material holding area is empty (filled with air). . The soil embedding case holding means is preferably a cylindrical body as shown in FIG. 18 in order to hold the soil embedding cases in series, but may hold the soil embedding case. Other shapes are possible if possible. Further, as shown in FIG. 18, a supply means (1806) for supplying the soil embedding case holding means to the soil embedding case holding means may be provided.

  The “soil embedding case dropping port” (1805) is vacated at the lower end in the longitudinal direction of the soil embedding case holding / falling portion (1801), and the soil embedding case holding / falling portion is extended from the soil embedding case holding / falling portion. A soil embedding case is supplied to (1802). The soil embedding case dropping port can be opened and closed by a soil embedding case standby section. The opening / closing operation of the soil embedding case dropping port will be described later.

  The “soil embedding case standby section” (1702) is configured to wait for the soil embedding case dropped from the soil embedding case dropping port. As shown in FIG. 18, the soil embedding case standby section (1802) receives the supply of the soil embedding case from the soil embedding case dropping port, and receives the pressure from the pressure rod (1803). It has an upper opening (1807) provided to receive pressure, and a lower opening (1808) provided to drive the soil embedding case into the soil by pressurization from the pressure rod. The soil embedding case standby unit can take a pressurizable state as shown in FIG. 17 and a tilted state as shown in FIG. The pressurizable state refers to a state where the soil embedding case standby portion is substantially perpendicular to the soil surface. In this state, it is possible to receive pressure from the pressure rod. In the tilted state, the upper opening of the soil embedding case standby portion and the soil embedding case dropping port are on substantially the same axis, and the soil embedding case holding falling portion from the soil embedding case standby portion This means that the soil embedding case standby part is tilted so that the soil embedding case can be supplied.

  As shown in FIG. 18, the length of the soil embedding case standby portion in the longitudinal direction is approximately the same as the length of the soil embedding case in the longitudinal direction, and the soil embedding case standby portion is tilted. Then, it is desirable to be able to hold one soil embedding case. In addition, a soil embedding case fall stop means (1810) is provided in the soil embedding case standby part, and the soil embedding from the soil embedding case dropping port is possible when the soil embedding case standby part can be pressurized. The falling case may be prevented from falling.

  FIG. 19 is a left side view of FIG. As shown in FIG. 19, the soil embedding case standby portion can be easily tilted by providing the soil embedding case standby portion and the tiltable lever (1605, 1901) that can be driven. The tilt lever is fixed to the soil embedding standby portion by welding or the like, and when the tilt lever is tilted, the soil embedding case standby portion is tilted about the rotation shaft (1902). When the tilt lever is tilted from the X direction to the Y direction in FIG. 19, the soil embedding case tilts about the rotation axis (1707) from the pressurizable state as shown in FIG. 17, and the tilt state shown in FIG. Become. Further, it is desirable that the moving range of the tilt lever is limited to a predetermined range so that the soil embedding case dropping port and the upper opening of the soil embedding case standby portion can be easily aligned.

  The “pressure rod” (1703) can pressurize the soil embedding case waiting in the soil embedding case standby section toward the soil surface. As shown in FIG. 17, when the soil embedding case standby portion is in a pressurizable state, when the pressure rod is moved downward, the upper portion of the soil embedding case is passed through the upper opening of the soil embedding case standby portion. Pressurized. Then, the soil embedding case is driven into the soil by pressurization from the pressure rod. For the sake of safety, it is desirable that the outer diameter of the pressure rod is covered with a cylindrical body (1606) as shown in FIG. The pressurizing method of the pressurizing rod may be a pedal type that pressurizes with a foot, may be an electric type that pressurizes by electric power, or may pressurize the soil embedding case. If possible, the mode is not limited. The pedal type is described in detail below.

  As shown in FIG. 17, a force can be easily transmitted to the pressure rod by providing the pedal with a “pedal” (1704) and a “support” (1706).

  Since the “pedal” (1704) is fixed to the pressure rod by the connecting member (1705), the pedal and the pressure rod follow. Therefore, a force can be applied to the pressure rod by depressing the pedal with a foot.

  The “supporting portion” (1706) is configured to support the pedal slidably on an axis provided in the direction of the pressure rod. In FIG. 17, since the support portion is fixed to the pedal, it follows the movement of the pedal. Further, it is slidably fitted to a cylindrical body (1708) covering the pressure rod. In FIG. 17, the cylindrical body (1708) corresponds to the axis provided in the direction of the pressure rod. Accordingly, when the pedal is depressed with the foot, the support portion slides on the cylindrical body. By having such a support portion, when a force is applied to the pedal, the moment does not concentrate on the joint portion between the pedal and the connecting member, and damage to the joint portion can be prevented. . In addition, as shown in FIG. 16, by connecting a plurality of adjacent support portions (1603) with the horizontal connecting rod (1604), the force applied to the pedal is efficiently dispersed and applied to each pressure rod. be able to.

  20A and 20B show a state where the pressure rod (2001) and the connecting member (2002a) are connected. FIG. 20A is a BB cross section in FIG. As shown to Fig.20 (a), the opening part (2004) is provided in a part of cylindrical body (2003), and the pressurization rod and the connection member are connected through the opening part. Moreover, the figure which looked at Fig.20 (a) from CC is shown in FIG.20 (b). In addition, the part which is hidden by the pedal which is originally shown with the dotted line is displayed. As shown in FIG. 20B, the cylindrical body (2003) is provided with an opening (2004), and the connecting rod moves up and down within the range of the opening to move the pressure rod up and down. Can be moved. In addition, the circular body currently displayed on FIG.20 (b) is the top part (2002b) of a connection member.

  As shown in FIG. 21, the support portion (2101) may be provided on a member different from the cylindrical body (2103). In FIG. 21, a rod-like body (2102) parallel to the tubular body is provided separately from the tubular body, and the support portion is slidably fitted to the rod-like body. The rod-shaped body is fixed to the cylindrical body by a horizontal rod-shaped body (2105). A DD cross section in FIG. 21 is shown in FIG. As shown in FIG. 22, the support portion (2201) is slidably fitted around a rod-like body (2202) parallel to the cylindrical body. As shown in FIG. 22, the rod-shaped body may be provided on the same plane as the cylindrical body, or may be disposed on a different plane from the cylindrical body. When the rod-shaped body and the cylindrical body are provided on the same plane, the portion where the horizontal connecting rod (2104) and the cylindrical body shown in FIG. It is necessary to deform in accordance with the shape of the body. In addition, the EE cross section in FIG. 21 becomes the same shape as FIG.

  It is desirable that the pressure rod is provided with elastic means for urging in the returning direction in order to return to the state before pressurization after pressing the soil case toward the soil surface. Even if the pressure rod is pressed with the soil embedding case facing the soil surface, the pressure rod itself is not deeply embedded in the soil. You don't need that much power to get it back. However, as illustrated in FIG. 16, by attaching an elastic means (1607) to the pressure rod, the operator can operate the pressure rod without having to bother to pull out the pressure rod from the soil embedding case standby unit. It is possible to return to the previous state. The elastic means may be a spring, rubber, or the like, and is not limited thereto as long as it can urge the pressure rod in a direction to return to the pre-pressure state.

  As shown in FIG. 16, wheels (1608) may be provided to facilitate the movement of the soil embedding case driving machine, or the soil embedding case driving machine may be operated easily. A handle (1609) may be provided. Moreover, as shown in FIG. 17, you may provide the fall prevention apparatus (1709) for preventing a fall.

  (Specific Example of Embodiment 6) A method of driving the soil embedding case with the soil embedding case driving machine of the present embodiment will be specifically described with reference to FIGS. The soil embedding case driving machine shown in FIG. 16 includes four pressure rods (1602) for driving the soil embedding case, and each of the pressure rods is covered with a cylindrical body (1606). And oriented to move perpendicular to the soil surface. A lower end of a coil spring (1607) for urging an upward force so as to return to a state before pressurization after pressurization of the pressurization rod is fixed to the upper end of the pressurization rod. The upper end of the coil spring is fixed to a handle (1609) for operating the soil embedding case driving machine.

  As shown in FIG. 17, when a pedal (1704) connected to the pressure rod by the connecting member (1705) is stepped on with a foot, a downward force is applied to the pressure rod to lower it. At this time, the pedal is supported by the support portion (1706), and the support portion follows the pedal and descends. By lowering the pressure rod, the soil embedding case in the soil embedding case standby section can be pressurized and driven into the soil.

  By adjusting the length of the pressure rod and the descendable range, it is possible to adjust the depth at which the pressure rod drives the soil embedding case. In addition, by driving the soil embedding case deeper than the soil surface, it is possible to prevent an infant or a pet from accidentally eating the soil permeation material in the soil embedding case. Further, when the soil surface is turf or the like, the lawn mower can be prevented from being damaged by the soil embedding case. Furthermore, it is preferable on the landscape that the top of the soil embedding case is hidden.

  When the foot is released from the pedal (1605), an upward force is applied to the pressure rod by the coil spring, and the pressure rod returns to the pre-pressure state. If the soil embedding case can be driven into the soil, the pressure rod itself does not penetrate deep into the soil, so that it can be easily returned to the pre-pressurization state together with the bias of the coil spring.

  Below each pressure rod, there is a corresponding soil embedding case standby section (1702), and in order to supply the soil embedding case to each soil embedding case standby section, the corresponding soil An embedded case drop holder (1701) is provided. When the tilt lever shown in FIG. 19 is tilted, the soil embedding case standby portion is tilted, and one soil embedding case is placed from each soil embedding case drop holding portion to the soil embedding case standby portion. Supplied. Then, when the tilting lever is returned, each soil embedding case standby section is in a pressurizable state. In this state, when the pressure rod is pressurized as described above, the soil embedding case is driven into the soil. By repeating this operation, the soil embedding case can be driven continuously.

  (Simple explanation of the effect of Embodiment 6) As mentioned above, in the soil embedding case driving machine of this embodiment, the soil embedding case described in Embodiments 1 to 5 is continuously applied over a wide range. It is possible to drive in. Therefore, it has an excellent effect that the soil infiltrating material can be efficiently supplied even in a large garden or golf course.
