Description

  The present invention relates to a soil net laying apparatus for burying a net for planting agricultural products in soil such as a farm field.

  In recent years, due to the aging of farmers and the shortage of workers, demands for labor saving in farming have increased, and labor saving equipment such as transplanters, harvesters, and adjusters have been developed and sold.

  For example, the cultivation period of bulbous vegetables, especially sea cucumbers, is almost half a year, but harvesting and adjustment in a series of processes such as planting, cultivation management, harvesting, and adjustment work (removal of roots and foliage from harvested sea cucumbers) The work share accounts for about 2/3 of the total work time. Furthermore, since this harvesting / adjustment work is concentrated at the end of the cultivation period, it was the biggest factor limiting the amount of production per farmhouse.

  Therefore, in order to save labor for harvesting and adjusting such crops, the inventors of the present application planted and cultivated crops on nets embedded in the soil, and then cultivated crops fixed to the nets by elongated roots. A method for harvesting and adjusting nets was proposed (Japanese Patent Application 2005-194514).

  When this method is applied to cultivation of sea cucumber, first, as shown in FIG. 6 (a), a net 30 is laid in the soil, and seed radish is planted and grown thereon. At this time, the root 41 extended from the bulb 40 passes through the eyes of the net 30 and spreads into the ground, but the bulb 40 that has grown and grown cannot pass through the eyes of the net 30, and is shown in FIG. Thus, the root part 41 of the rakkyo is located on the lower surface of the net 30, and the bulb part 40 is located on the upper surface. Since the grown raccoon is fixed to the net 30 by its own root 41, it can be easily harvested by lifting the net 30 from the soil. As shown in FIG. 7, the harvested raccoon is introduced into the adjusting device while being fixed to the net 30, and the bulb portion is formed by the rotary blades 51 and 52 provided at a predetermined distance from the net surface. The stem and leaf part 42 and the root part 41 are excised from 40.

  As described above, according to the cultivation, harvesting, and adjustment method of crops using a net, it is possible to perform harvesting and adjustment operations on a large number of crops fixed on the net at a time. Compared to harvesting and adjusting each stock, the burden on the operator can be greatly reduced.

  In implementing the cultivation, harvesting, and adjustment methods of crops using the net as described above, it is first necessary to lay a net for planting the crop in the soil. For this purpose, it is necessary to first dig the ground surface to a certain depth, lay a net on it, and bury the net by covering the top surface of the net with soil. However, if such a net laying operation is performed manually, a great deal of labor and time are required.

  Therefore, the problem to be solved by the present invention is to provide a ground net laying device capable of greatly saving the above-described net laying work.

The underground net laying device according to the present invention made to solve the above problems is an underground net laying device for laying a net for plant cultivation in the soil,
a) traveling means;
b) a groove forming means for excavating the soil ahead of the traveling direction to form grooves on the ground surface and discharging the excavated soil to the left and right of the grooves;
c) net laying means for laying the net on the bottom of the groove by extending the net in a direction opposite to the traveling direction;
d) earthing means for covering the net with earth by bringing the soil discharged to the left and right of the groove by the groove forming means to the center of the groove;
It is characterized by having.

  According to the net laying device of the present invention having the above-described configuration, the formation of a net laying groove, the laying of the net in the groove, and the earthing on the net are automatically performed as the device is advanced by the traveling means. Since this is done, the work of laying nets in the ground can be greatly saved. For this reason, it is possible to cultivate crops using the net as described above on a large scale with a small number of workers and a short work time. The net laying device of the present invention can be applied to the cultivation of various plants, but can be suitably used particularly for the cultivation of bulbous vegetables such as sea cucumbers and small potatoes.

  Hereinafter, the best mode for carrying out the present invention will be described using embodiments. 1-3 is a figure which shows schematic structure of the net laying apparatus based on a present Example, FIG. 1 is a side view, FIG. 2 is a top view, FIG. 3 is a front view. FIG. 4 shows a cross section of the soil at the points indicated by arrows (a) to (g) in FIG. Hereinafter, the front, rear, left and right are defined with the traveling direction of the net laying machine (the left direction in FIG. 1) as the front.

  The net laying machine of the present embodiment has a traveling machine body 10 provided with a tire 11 and a drive mechanism (not shown) for driving the tire 11, forming a net laying groove, and forming a net in the groove. It is self-propelled in the field while laying and laying the soil on the net.

  The trough 12 provided in the lower front part of the traveling machine body 10 excavates the soil forward in the traveling direction to form a groove 21 having a width of about 20 to 30 cm, and the excavated soil follows a curve provided on the upper surface of the trough. To the left and right of the groove 21 (FIGS. 4A to 4D). At this time, it is desirable that the rod 12 can swing up and down and / or right and left.

  A net support portion 13 for supporting a roll-shaped net 20 is provided at the upper portion of the traveling machine body 10, and the net 20 supplied from the net support portion 13 to the ground surface is provided at the rear of the cage 12. The net laying roller 14 is pressed against the bottom surface of the groove 21 (FIG. 4D), and is fed out in the direction opposite to the traveling direction as the machine body 10 travels. In addition, the start part of the net | network 20 is previously stopped on the ground surface by the fixing means, such as the pile 22, before pressing work, or is pressed down with soil. In addition, since the optimal depth of the groove 21 for laying the net 20 varies depending on the crop to be planted, it is desirable that the rod 12 and the net laying roller 14 can be vertically adjusted with respect to the traveling machine body 10. .

  In addition, the net | network 20 uses the thing of the magnitude | size of the magnitude | size which does not prevent passage and progress of the root of crops, and the magnitude | size which is the extent which the main body (bulb part and foliage part) of crops does not fall out at the time of harvest. Furthermore, it is desirable to use a material having a strength that can withstand the stress of harvesting and adjusting operations. For example, when it is used repeatedly for a plurality of years, it is desirable to use a net made of a synthetic resin, having a stitch size of about 2 mm to 10 mm and having a strength capable of withstanding the stress at the time of harvest. On the other hand, when disposable in a single year, the net 20 can be a non-woven fabric with a coarse texture to the extent that the roots can easily pass through, a net knitted with cotton yarn, or the like.

  Behind the net laying roller 14, there is provided a mulching mechanism 15 having a pair of left and right mulching plates 15a and 15b. The soil gathering mechanism 15 functions to cover the upper surface of the net 20 laid on the bottom of the groove 21 with the soil by bringing the soil discharged to the left and right of the groove 21 by the saddle 12 to the center. Each of the mulch plates 15a and 15b is disposed substantially perpendicular to the ground surface, and has a curved shape such that the distance between the mulch plates 15a and 15b becomes narrower from the front to the rear of the airframe 10. The soil taken in from the front of the earthing mechanism 15 is sandwiched between two earthing plates 15a and 15b whose intervals become narrower toward the rear, and are brought to the center of the groove 21 (FIG. 4 (e), (F)).

  Here, it is desirable that the operator can adjust the distance between the earthing mechanism 15 and the ground surface (that is, the vertical position of the earthing mechanism 15 with respect to the airframe 10) and / or the distance between the left and right earthing plates 15a and 15b as appropriate. By adjusting these appropriately, the excavated soil can be completely returned to the groove 21, or a recess can be left in the center of the groove 21. When a dent is left in the center of the groove 21, the dent hits the center of the groove 21 and can be used as a guide when planting. In addition, when the bulb 24 or the like is planted on the bottom of the V-shaped dent 23 as shown in FIG. 4G, the plant is initially in a shallow planting state, and then the soil naturally collapses and gradually becomes a deep planting state. Become. For this reason, immediately after planting, it can be suitably used for planting crops such as sea urchins, which are preferably shallow planted in order to accelerate growth, and deeply planted in order to whiten the rhizomes as they grow.

  The best mode for carrying out the present invention has been described above using the embodiments. However, the present invention is not limited to this, and appropriate modifications are allowed within the scope of the present invention. . For example, the shape of the ridge used in the net laying device of the present invention may be, for example, a rotating spiral ridge 16 as shown in FIG. In this case, the cover 16a is provided on the rear side in the traveling direction so that the soil is discharged only in the traveling direction and the lateral direction. Moreover, in the said Example, although the structure which uses a tire as a traveling means was shown, it is good also as a structure which uses an endless track. In addition, the underground net laying device of the present invention can be realized by using an existing agricultural machine such as a tractor as a traveling means and pulling the groove forming means, the net laying means, the earthing means, etc. to the agricultural machine. .

  Furthermore, the net laying device of the present invention has a configuration in which a plurality of sets of groove forming means, net laying means, and earthing means are provided for one traveling machine body, and a plurality of nets can be laid in parallel at one time. It is good also as a possible structure. This makes it possible to further improve the efficiency of net installation work.
