Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments.

Examples

Fig. 1 shows a schematic structure of a cultivation system, and the cultivation system for raising seedlings of forest tree according to the present application includes a substrate layer 100 disposed on a bottom layer, a supporting frame 200 disposed on the substrate layer 100, and a container 300 for cultivating plants placed on the supporting frame 200.

The matrix layer 100 is a medium for plant cultivation that provides support for plants and is capable of retaining moisture and nutrients to facilitate plant root growth, typically the components of the matrix layer 100 include vermiculite, perlite, peat moss, coconut coir, polymer matrix (e.g., rock wool), crushed bark or wood chips, gravel or sand.

Fig. 2 shows a schematic structural diagram of a support frame 200, where the support frame 200 includes a first plate 210 and a second plate 220 that are arranged in an angle shape, a plurality of first through holes 211 are provided on the first plate 210, a third plate 230 attached to the first plate 210 is further provided at a connection position between the first plate 210 and the second plate 220, and the third plate 230 can perform relative movement with the first plate 210 to generate a shearing effect.

Fig. 3 shows a schematic structure of a container 300, wherein the top of the container 300 is opened to fill the culture medium and cultivate the seedlings, the container 300 is provided with a bottom 310 and a side wall 320 connected with the bottom 310, the bottom 310 is provided with a second through hole 311 to facilitate the root system of the seedlings cultivated in the container 300 to grow downwards into the substrate layer 100 at the bottom through the second through hole 311, and in addition, the side wall 320 can be provided with a side hole 321 to facilitate ventilation of the root system according to requirements.

Referring to fig. 1 to 3, an angular structure is formed between the first plate 210 and the second plate 220, corresponding protrusions having slopes 110 are formed on the surface of the substrate layer 100, the support frame 200 is placed on the substrate layer 100 before cultivation, the angular structure of the support frame 200 is placed corresponding to the slopes 110, the container 300 with seedlings cultivated is placed on the first plate 210 of the support frame 200, and normal maintenance is performed on the seedlings cultivated in the container 300, so that root systems of the seedlings are pricked into the substrate layer 100 below, and unified management and maintenance of the seedlings are facilitated.

In the present application, although the surface of the substrate layer 100 may be sufficiently shaped to form the protrusion with the slope 110 by trimming, the protrusion with the slope 110 is still the substrate layer 100, and has no stability, and the post curing stamp is easy to collapse or deform, so that the support frame 200 is placed on the substrate layer 100 to provide a stable slope for placing the container 300, avoiding the slope 110 itself to directly support the container 300, and meanwhile, the adaptive shape of the support frame 200 plays a role of a cage for maintaining the protruding state for a long time, and on the other hand, due to the angular structure of the plate one 210 and the plate two 220 provided by the adaptive slope 110, the bearing surface of the container 300 is divided into strips spaced from each other on the premise of almost not changing the whole placing area, thereby further facilitating the installation of the plate three 230 and the plate one 210, enabling the relative movement of the plate three 230 and the plate one 210 when needed, forming a shearing effect, and further enabling the root system through the through hole two 311 to be pricked into the substrate layer 100, thereby facilitating the separation of the container 300 and the substrate layer 100.

In still another aspect, since the root system is directly cut off from the first plate 210, the cut root system remains in the convex and the substrate layer 100 below, and when the root system is cleaned before the subsequent cultivation, the convex can be cleaned directly by pushing and leveling to expose the residual root system, so that the residual root system can be cleaned conveniently.

In the present application, optionally, the bottom 310 of the container 300 is also provided with an inclined surface, and the inclined surface state of the bottom 310 described in the present application is opposite to the opening surface of the container 300, that is, the state that the bottom of the container 300 is parallel to the opening is changed, and the inclined angle of the inclined surface of the bottom 310 is the same as the inclined angle of the inclined surface 110, so that when the container 300 is placed on the first plate 210, the opening level of the container 300 can be adjusted, and the main branches of the plant seedlings cultivated in the container 300 keep upright to grow, so as to avoid the deformation of the plant seedlings caused by the inclined growth.

Fig. 4 shows a schematic structural diagram of a third plate 230, where the third plate 230 is provided with a third through hole 231, and the third through hole 231 may correspond to the first through hole 211 in a certain state, so as to expose the bottom substrate layer 100, so that the root system enters the substrate layer 100 through the first through hole 211 and the third through hole 231.

The third plate 230 is further provided with a spring piece 232 protruding out of the plane of the third plate body, the thickness of the spring piece 232 is smaller than that of the third plate 230, so that the spring piece 232 can deform and shrink towards the inside of the third plate 230, and the spring piece 232 is used for being matched with the first plate 210 to limit the position of the third plate 230 so that the third through hole 231 corresponds to the first through hole 211.

Fig. 5 shows a schematic diagram of the matching state of the third plate 230 and the first plate 210, in which the first plate 210 is attached to the lower surface of the third plate 230 in the use state, so that the upper surface of the third plate 230 can be used for placing the container 300 without obstruction, and the third plate 230 can also move relative to the first plate 210 without obstruction, and at least a part of the edge of the third through hole 231 is a chamfer 233, so that when the third plate 230 moves relative to the first plate 210 along the direction a, the cutting direction of the chamfer 233 is the same as the moving direction of the third plate 230, and the chamfer 233 matches with the first plate 210 to form a shearing action on root systems, so that all root systems growing into the matrix layer 100 can be cut off rapidly.

With further reference to fig. 2, plate three 230 is inserted through the junction of plate one 210 and plate two 220, and plate three 230 is still partially exposed to the exterior of plate one 210, which can be pushed into support 200 by external application, thereby creating the mobile state of plate three 230 of fig. 5.

Fig. 6 shows an assembly structure of a third plate 230, which is disposed on a bottom surface of the first plate 210 (i.e., a surface contacting the substrate layer 100), two symmetrically disposed L-shaped ribs 212 are disposed at the bottom of the first plate 210, the L-shaped ribs 212 and the first plate 210 form a slot for accommodating the third plate 230 to slide, the L-shaped ribs 212 have a notch 213, the notch 213 correspondingly accommodates a spring plate 232, when the third plate 230 is not subject to external force, the protruding structure of the spring plate 232 abuts against the edge of the notch 213, and the movement of the third plate 230 along the a direction is limited to maintain the corresponding state of the third through hole 231 and the first through hole 211, and once the external force is applied to the third plate 230, the spring plate 232 is deformed by compression and slides into the L-shaped ribs 212.

Referring to fig. 2, the support 200 further has a fourth plate 240 connected to the second plate 220, the fourth plate 240 is disposed on a side far away from the first plate 210, and the fourth plate 240 is disposed horizontally in a use state to be attached to the surface of the substrate layer 100, and the contact area is increased by the contact between the fourth plate 240 and the substrate layer 100, so that the gravity applied to the container 300 is partially shared by the fourth plate 240, which avoids the problem that the support 200 sinks due to the large pressure caused by the contact between the edge of the second plate 220 and the substrate layer 100, and further avoids the problem that the slope 110 collapses.

In another embodiment, the container 300 is further provided with a grip structure to facilitate lifting, see fig. 7, and the side wall of the container 300 is provided with an outer pull ring 330. One of the outer pull ring 330 has been formed by directly forming an opening in the side wall of the container 300, such that the upper portion of the opening forms the outer pull ring 330 as part of the container 300, or by forming an additional outer pull ring 330 directly on the rim of the container 300, i.e. the outer pull ring 330 is higher than the rim of the container 300.

With the exemplary illustration of the structure of the outer pull ring 330 shown in fig. 7, and with the enlarged view of fig. 8 showing the position B of fig. 7, the outer pull ring 330 is positioned at the greatest vertical distance from the edge of the bottom 310, i.e., the outer pull ring 330 is positioned at the lower side of the slope where the bottom 310 is located, so that the container 300 can be kept upright during the process of pulling the moving container 300, and because the bottom 310 of the container 300 is of a slope design, the center of gravity is more biased to the lower side of the bottom 310 during the pulling process, and the outer pull ring 330 is positioned at the lower side of the bottom 310, so that the vertical distance between the direction of the force applied to the outer pull ring 330 and the center of gravity of the container 300 is smaller, and the deflection of the container 300 during the pulling process is also smaller, which is beneficial to keep the container 300 upright, and the matrix inside of the container 300 from slipping out due to the excessive tilting of the container 300.

Further, a movable side plate 340 is further disposed on the outer wall of the container 300, two protrusions 341 are disposed at the bottom of the side plate 340, the distance between the two protrusions 341 is the same as the distance between the adjacent first through holes 211, the top of the side plate 340 is connected with a swinging plate 342, the other end of the swinging plate 342 is connected with an inner pull ring 343, a connecting piece 344 is disposed in the middle of the swinging plate 342, and the other end of the connecting piece 344 is connected with the container 300.

In addition, referring to fig. 9, the side plate 340 is further connected to the side wall 320 of the container 300 through the second connection piece 345, the second connection piece 345 and the first connection piece 344 maintain the same inclination angle, and the inclination state of the first connection piece 344 is opposite to the inclination state of the bottom 310 of the container 300, that is, as shown in fig. 8, the bottom 310 of the container 300 is lower left and higher right, and the second connection piece 345 and the first connection piece 344 are lower left and higher right.

Based on the above-mentioned holding structure, in the process of raising seedlings, a worker needs to lift the container 300 with the tree seedlings cultivated thereon by the outer pull ring 330 and place the container on the support frame 200, and in the process of lifting the container 300, the hands simultaneously act on the inner pull ring 343, the inner pull ring 343 is upwards close to the outer pull ring 330 until the inner pull ring 343 is attached to the outer pull ring 330, in the process, the swing plate 342 swings at the connection position of the first connecting sheet 344 to press the side plate 340, and simultaneously, under the cooperative action of the second connecting sheet 345, the whole side plate 340 moves downwards and the protrusion 341 extends beyond the edge of the bottom 310, and when the container 300 is placed on the support frame 200, the protrusion 341 is correspondingly inserted into the first through hole 211.

When the first through holes 211 of the support frame 200 are arranged in the rectangular array along the length-width direction, the container 300 can be ensured to maintain relatively accurate and consistent upright performance after being placed on the support frame 200, because the first through holes 211 of the rectangular array along the length-width direction only have the distance between two adjacent first through holes 211 along the length direction and the distance between two adjacent first through holes 211 along the width direction equal to the distance between the two protrusions 341, and the distance between the two inclined through holes 211 is larger than the distance between the two protrusions 341, when the container 300 is placed, the inclined state of the container 300 is quite obvious when the protrusions 341 are correspondingly inserted into the two adjacent first through holes 211 along the width direction, and the state of the hands can be adjusted by a larger angle when the container 300 is placed, so that the upright placement of the container 300 can be realized more conveniently.

Fig. 10 shows another embodiment of the arrangement of the substrate layer 100 and the support frame 200, wherein the protrusions with the slopes 110 on the surface of the substrate layer 100 are arranged in groups, each group has two symmetrical slopes 110, and the high points of the two slopes 110 are close to each other, and the support frame 200 is arranged to correspond to the shape of the slopes 110, that is, the support frame 200 includes a first plate 210 and a second plate 220 which are symmetrically arranged, the first plate 210 and the second plate 220 are connected in an angle, a fourth plate 240 which is horizontally arranged is connected with the second plate 220 on two sides, a fifth plate 251 and a sixth plate 252 are arranged on the lower surface of the first plate 210, the fifth plate 251 and the sixth plate 252 are mutually attached, but the upper and lower positions of the fifth plate 251 and the sixth plate 252 are not limited.

And the through hole IV 251b of the plate V251 is provided with a section of chamfer II 251C, the through hole V252 b of the plate V252 is provided with a section of chamfer III 252C, and when the plate V251 and the plate V252 relatively move to shear, the chamfer II 251C is the same as the movement direction C1 of the plate V251, the chamfer III 252C is the same as the movement direction C2 of the plate V252, and the surface of the cutting edge formed by the chamfer II 251C is mutually attached to the surface of the cutting edge formed by the chamfer III 252C, so that a better shearing effect can be achieved.

In addition, a pressing rod 260 is disposed in the middle of each set of slope surfaces 110, two sides of the pressing rod 260 are provided with convex wings 261, the convex wings 261 have inclined contact surfaces 262, the contact surfaces 262 of the convex wings 261 on two sides are opposite in inclination direction, the plate five 251 and the plate six 252 are respectively contacted with the contact surfaces 262 of the convex wings 261 on two sides, as shown in fig. 10, the edge of the plate five 251 directly abuts against the contact surface 262 on the proximal end, the plate six 252 has an extension arm 252a abutting against the contact surface 262 on the distal end, when the pressing rod 260 moves downwards, the contact surfaces 262 on two sides respectively press the plate five 251 and the plate six 252, so that the plate five 251 is pressed into the plate one 210, the plate six 252 is pulled outwards, and the plate five 251 and the plate six 252 directly form shearing through relative movement so as to cut off and separate root systems more quickly, and by one operation of the pressing rod 260, root systems on the two sides 110 can be simultaneously cut off and separated, and efficiency of separation operation is further improved.

It should be noted that the description above in connection with fig. 10 is merely to provide a preferred embodiment, and is not intended to be limiting, and the actual application may be allowed to provide the slope 110 on one side according to the requirement, and the installation of only the fifth plate 251 or the sixth plate 252 is also allowed.

In order to maintain stability of the compression bar 260, the base 263 is disposed on the plate four 240, so that the lower end of the compression bar 260 is slidably disposed in the base 263, so that stability of movement of the compression bar 260 in a vertical direction can be maintained, meanwhile, a spring (not shown in the figure) can be disposed in the base 263 to abut against the compression bar 260, on one hand, when the compression bar 260 is not operated, the spring is used for pushing up the compression bar 260 to maintain an upper state of the compression bar 260, and on the other hand, after the compression bar 260 is pushed down to be in a lower state, the spring can play a role of resetting the compression bar 260.

More specifically, when the root system is not needed to be sheared and separated, the compression bar 260 is in an upper state, the tension spring is in a natural non-stretching state, the extension arm 252a of the plate six 252 is naturally attached to the contact surface 262, the plate five 251 can slide downwards under the gravity force due to the fact that the spring plate 232 is not arranged, the tension spring can be connected with the edge of the plate five 251 to limit the plate five 251 to slide downwards, so that the edge of the plate five 251 is naturally attached to the contact surface 262, when the root system is sheared and separated, the compression bar 260 is changed from the upper state to the lower state, and the tension spring is stretched to store elastic potential energy, once the pressure on the compression bar 260 is released, the compression bar 260 is jacked up by the spring in the base 263, and meanwhile, the tension spring also contracts to pull the plate five 251 and the plate six 252 to return the plate five 251 to the initial state.
