Description

Technical Field

[0001] The present invention relates to the technical field of cultivation and soil preparation, and in particular to a device and method for symbiotic cultivation of mushrooms and plants. Background Art

[0002] Symbiotic cultivation of mushrooms and plants is a highly efficient ecological planting model. Its core lies in the use of mycorrhizal fungi to form a mutually beneficial symbiotic relationship with plant roots. However, this cultivation method has special requirements for soil structure. The mycelial network needs to grow stably in the lower soil layer. Therefore, it is necessary to strictly avoid disturbing the lower soil layer during land preparation. At the same time, the upper soil layer needs to be kept loose and porous to ensure sufficient contact between the mycelium and the plant roots and oxygen circulation.

[0003] At present, rotary tillers are widely used in the agricultural field for soil preparation. Rotary tillers are generally installed at the rear of tractors. Their typical working process is: the tractor's power output shaft drives the rotary tiller's rotating shaft to rotate at high speed, driving the circumferentially distributed tilling blades to continuously cut into the soil. The tilling blades cut and throw the soil through rotation and collide with subsequent blades to achieve soil crushing and mixing.

[0004] However, when traditional rotary tillers are used in the symbiotic cultivation of mushrooms and plants, there are still the following defects: First, the end of the rotary tiller's plowing blade passes through the upper and lower soil layers in an arc-shaped trajectory during rotation. The rotational thrust will destroy the original structure of the lower soil. Especially when the blade moves to the junction of the upper and lower soil layers, the strong shearing and stirring action can easily tear the formed mycelium network, seriously hindering the establishment of the symbiotic system.

[0005] Secondly, the rotary tiller relies on the rotation of the blade to break up the soil. Although it can break up the soil clods, it is difficult to form a uniform and stable pore structure at the bottom of the upper soil. The broken soil is easily re-compacted under the action of gravity, which cannot provide a loose environment for the continuous growth of mycelium, resulting in reduced mycelium colonization efficiency. Summary of the Invention

[0007] The anti-interference mechanism includes a partition block connected to the lower part of the carrier frame through a connecting component, and a plurality of cutting teeth slidably connected to the partition block are arranged at equal intervals along the front-to-back direction. The anti-interference mechanism also includes a driving component for driving the cutting teeth to move back and forth and cut the soil into layers.

[0008] The land leveling mechanism includes a rotating shaft rotatably arranged inside the carrier and located on the upper part of the partition block. A plurality of plowing blades fixedly connected to the rotating shaft are arranged at equal intervals along the front-to-back direction. The rear end of the rotating shaft is connected to the power output end of the self-propelled device.

[0009] Preferably, the connecting assembly includes an annular sleeve rotatably arranged in front of the lower side of the carrier frame, a linkage rod is fixedly installed on the front side of the partition block, and the linkage rod is connected to the annular sleeve in a front-to-rear sliding manner.

[0010] Preferably, a rocking plate is fixedly mounted on the outer side of the annular sleeve, a hydraulic push rod is hinged between the end of the rocking plate away from the axis of the annular sleeve and the supporting frame, and a limiting groove for ninety-degree deflection of the rocking plate is provided at the lower part of the supporting frame.

[0011] Preferably, the driving assembly includes a rotating ring rotatably arranged at the rear of the lower side of the carrier, the rotating ring is connected to the rotating shaft through a belt, and a reciprocating threaded rod threadedly connected to the rotating ring is fixedly installed on the rear side of the partition block.

[0012] Preferably, the right side of the cutting tooth is a tetrahedron structure with a flat lower portion, and the left side is a block structure slidably connected to the interior of the separation block, and a coil spring is provided between the block structure of the cutting tooth and the separation block.

[0013] Preferably, the lower side of the cutting teeth is provided with a chamfer, a pressing plate is slidably connected to the partition block, the sliding direction of the pressing plate is perpendicular to the sliding direction of the cutting teeth, and a tension spring is provided between the pressing plate and the partition block.

[0014] Preferably, a plurality of wedge-shaped plates are fixedly mounted on one side of the pressing plate facing the interior of the partition block at equal intervals along the front-to-back direction, and the wedge-shaped plates correspond to the cutting teeth one by one.

[0015] Preferably, a plurality of bulldozer plates are hingedly connected at equal intervals along the front-to-back direction on the partition block, the bulldozer plates are arranged adjacent to the cutting teeth, fan-shaped grooves are provided on the bulldozer plates, and blocking blocks are fixedly installed at equal intervals along the front-to-back direction on the partition block, and the blocking blocks correspond to the fan-shaped grooves one by one.

[0016] Preferably, a group of combing grooves are provided on the front and rear sides of the bulldozer blade, and each group is composed of a number of combing grooves with different inclination angles, and a number of blocking blocks are fixedly installed inside the combing grooves.

[0017] Preferably, the present invention also provides a method for symbiotic cultivation of mushrooms and plants, and the cultivation method steps are as follows: S1, the self-propelled device drives the opener to rotate, and the opener drives the cutting teeth to move back and forth repeatedly through the driving component, and then moves the carrier downward.

[0018] S2. The carrier drives the cutting teeth at the bottom of the partition block to be inserted into the soil, and the partition block is located at the junction of the lower layer and the lower layer of the soil, and then the partition block is rotated so that the cutting teeth face the moving direction of the self-propelled device.

[0019] S3. The mobile self-propelled device drives the reclamation blade and the separator to move synchronously. The cutting teeth cut and layer the soil by moving back and forth, and push the upper layer of soil upward, with less disturbance to the lower layer of soil.

[0020] S4. The reclaiming knife turns over the upper soil and the soil pushed upward by the cutting teeth, thereby loosening the upper soil with minimal disturbance of the lower soil.

[0021] S5. After the soil is prepared, the mushrooms and plants are planted together in the soil to form a mycorrhizal relationship between the mushrooms and the plants, thereby assisting the growth of the mushrooms.

[0022] The beneficial effects of the present invention are: 1. The present invention adopts a supporting frame to drive the partition block to descend to the junction of the upper and lower layers of soil, so that the partition block forms a physical isolation barrier. The tillage knife is strictly restricted to the upper space of the partition block during operation, avoiding its rotation trajectory from penetrating the lower soil. At the same time, the driving component drives the cutting teeth to move back and forth, and the horizontal cutting action replaces the rotation disturbance of the traditional rotary tillage knife, which significantly reduces the shear force at the soil stratification interface and reduces the damage to the mycelium network in the lower soil.

[0023] 2. The present invention uses cutting teeth to push the soil upward through their own shape during horizontal movement. When the dividing block moves forward with the self-propelled device, the tetrahedral structure of the cutting teeth continues to lift the upper soil upward, forming a continuous gap belt on the side of the dividing block opposite to its moving direction. The synchronously moving bulldozer pushes the soil upward along the surface of the dividing block, further enhancing the separation effect of the upper and lower soil layers and creating a stable pore structure for the bottom of the upper soil.

[0024] 3. The present invention uses the front and rear working surfaces of the bulldozer to dynamically comb the soil. The partition blocks move back and forth, so that the combing grooves on the front and rear sides of the bulldozer can divert soil particles in multiple directions. The blocking blocks in the grooves force the soil flow to produce a velocity gradient, and finally form a non-uniform pore network at the bottom of the upper soil layer, which significantly increases the space for mycelium growth.

[0025] 4. The present invention adopts the linkage between cutting teeth and pressing plates to form an anti-interference mechanism. When the cutting teeth encounter the obstruction of lumped soil, they synchronously push the wedge plate to press the pressing plate downward, so that the pressing plate moves downward and compacts the surface of the lower soil, effectively preventing the lumped soil from disturbing the lower soil when it is deflected by the push of the cutting teeth.

[0035] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0036] See Figure 1 and Figure 2 A mushroom and plant symbiotic cultivation device includes a frame 1 for connecting to a self-propelled device, a supporting frame 2 is provided on the lower side of the frame 1 for sliding up and down, an anti-interference mechanism 3 for separating the upper and lower layers of soil, and a land preparation mechanism 4 for loosening the upper layer of soil is provided on the supporting frame 2.

[0037] When it is necessary to prepare the land for the symbiotic cultivation of mushrooms and plants, the frame 1 is first connected to the self-propelled device, and then the operator controls the self-propelled device to drive the frame 1 to move to the position where the land needs to be prepared, and enables the self-propelled device to drive the anti-disturbance mechanism 3 and the land preparation mechanism 4, and then lowers the carrier frame 2 to the specified position, and then moves the self-propelled device so that the self-propelled device drives the anti-disturbance mechanism 3 and the land preparation mechanism 4 through the carrier frame 2 to turn over the upper layer of the soil, thereby increasing the looseness of the upper soil and reducing the disturbance to the lower soil.

[0038] It should be noted that a hydraulic cylinder is fixedly installed on the lower side of the frame 1, and the telescopic section of the hydraulic cylinder is fixedly connected to the carrier frame 2. In this embodiment, the self-propelled device adopts a tractor in the prior art, and the right side of the frame 1 is fixedly connected to the tractor by bolts, so that when leveling the land, the tractor drives the frame 1 to move to the right.

[0039] Continue reading Figure 1 and Figure 2 The anti-disturbance mechanism 3 includes a partition block 32 connected to the lower part of the carrier 2 through a connecting component 31. A plurality of cutting teeth 33 slidably connected to the partition block 32 are arranged at equal intervals along the front-to-back direction. The anti-disturbance mechanism 3 also includes a driving component 34 for driving the cutting teeth 33 to move back and forth and cut the soil into layers.

[0040] Continue reading Figure 1 and Figure 2 The land leveling mechanism 4 includes a rotating shaft 41 rotatably arranged inside the carrier 2 and located on the upper part of the partition block 32. A plurality of plowing blades 42 fixedly connected to the rotating shaft 41 are arranged at equal intervals along the front-to-back direction. The rear end of the rotating shaft 41 is connected to the power output end of the self-propelled device.

[0041] It should be noted that a pulley is fixedly installed at the rear end of the rotating shaft 41 , and the pulley is connected to the power output shaft of the tractor through a belt, so that the tractor can drive the rotating shaft 41 to rotate.

[0042] See Figure 2 、 Figure 3 and Figure 6 The right side of the cutting tooth 33 is a tetrahedron structure with a flat lower part, and the left side is a block structure slidably connected to the inside of the partition block 32. A coil spring is provided between the block structure of the cutting tooth 33 and the partition block 32.

[0043] In the initial state, the dividing block 32 drives the cutting teeth 33 to deflect, so that the cutting teeth 33 are located at the lower part of the dividing block 32, that is, the tetrahedral structure of the cutting teeth 33 is at the bottom and its block structure is at the top. When the tractor drives the dividing block 32 to move to the starting position of land preparation through the frame 1, the dividing block 32 and the plowing knife 42 are both located at the upper part of the starting position of land preparation. Then the operator controls the tractor to drive the rotating shaft 41 to rotate at high speed, and the rotating shaft 41 drives the plowing knife 42 to rotate synchronously.

[0044] See Figure 2 and Figure 5 The driving assembly 34 includes a rotating ring 341 rotatably arranged at the rear of the lower side of the carrier 2. The rotating ring 341 is connected to the rotating shaft 41 through a belt. A reciprocating threaded rod 342 threadedly connected to the rotating ring 341 is fixedly installed on the rear side of the partition block 32.

[0045] When the rotating shaft 41 starts to rotate at high speed, the rotating shaft 41 drives the rotating ring 341 to start rotating synchronously, and the rotating ring 341 then drives the reciprocating threaded rod 342 to move back and forth. The reciprocating threaded rod 342 drives all the cutting teeth 33 thereon to move back and forth through the dividing block 32. At the same time, the telescopic section of the hydraulic cylinder is extended, so that the hydraulic cylinder pushes the supporting frame 2 to move downward, and the supporting frame 2 drives the dividing block 32, the cutting teeth 33 and the clearing knife 42 to move downward synchronously.

[0046] When the cutting teeth 33 come into contact with the soil, the cutting teeth 33 that move back and forth cut the soil, and as the supporting frame 2 moves downward, the cutting teeth 33 and the dividing blocks 32 gradually insert downward into the soil. Then the supporting frame 2 drives the rotating cultivating blade 42 to come into contact with the upper soil, so that the cultivating blade 42 turns over and loosens the upper soil.

[0047] When the support frame 2 moves downward to a specified distance and stops, the partition block 32 moves to the junction of the upper soil and the lower soil, and the plowing knife 42 is located above the upper soil, so that the partition block 32 forms a physical isolation barrier, strictly limiting the plowing knife 42 to the upper space of the partition block 32, preventing its rotation trajectory from penetrating the lower soil.

[0048] See Figure 1 、 Figure 2 and Figure 4 The connecting assembly 31 includes an annular sleeve 311 rotatably arranged in front of the lower side of the carrier 2, and a linkage rod 312 is fixedly installed on the front side of the partition block 32. The linkage rod 312 is connected to the annular sleeve 311 in a front-to-back sliding manner.

[0049] See Figure 1 、 Figure 2 and Figure 4A rocking plate 313 is fixedly installed on the outside of the annular sleeve 311. A hydraulic push rod 314 is hinged between the end of the rocking plate 313 away from the axis of the annular sleeve 311 and the supporting frame 2. A limiting groove is provided at the bottom of the supporting frame 2 for the rocking plate 313 to deflect by ninety degrees.

[0050] When the dividing block 32 moves to the junction of the upper soil and the lower soil, the telescopic section of the hydraulic push rod 314 is extended, so that the hydraulic push rod 314 pushes the swing plate 313 to rotate, so that the swing plate 313 rotates to abut against the lower inner wall of the limiting groove, which causes the swing plate 313 to deflect downward by ninety degrees. The swing plate 313 drives the linkage rod 312 to rotate synchronously by ninety degrees through the annular sleeve 311, so that the linkage rod 312 drives the cutting teeth 33 to rotate ninety degrees to the right through the dividing block 32.

[0051] At this time, the cutting tooth 33 is located on the right side of the dividing block 32, that is, the tetrahedral structure of the cutting tooth 33 is on the right and its block structure is on the left. Then the tractor starts to move to the right, so that the tractor drives the cutting tooth 33, the dividing block 32 and the clearing knife 42 to move to the right synchronously by pulling the frame 1, so that the cutting tooth 33 moving back and forth continuously cuts the soil on the right, and pushes the cut soil upward to the upper part of the dividing block 32 through the upper side of the tetrahedral structure of the cutting tooth 33.

[0052] The partition block 32 forms an isolation zone between the upper soil and the lower soil, and at the same time forms a gap on the left side of the partition block 32. As the soil on the left side of the partition block 32 collapses downward, more irregularly arranged gaps are formed in the lower part of the upper soil, which is conducive to the growth of mycelium.

[0053] See Figure 2 、 Figure 6 and Figure 7 A number of bulldozer plates 323 are hingedly connected to the partition block 32 at equal intervals along the front-to-back direction. The bulldozer plates 323 are arranged adjacent to the cutting teeth 33. A fan-shaped groove is provided on the bulldozer plates 323. Blocking blocks 324 are fixedly installed on the partition block 32 at equal intervals along the front-to-back direction. The blocking blocks 324 correspond one-to-one to the fan-shaped grooves.

[0054] When the cutting teeth 33 are located on the right side of the dividing block 32, the dividing block 32 drives the bulldozer 323 to rotate to the upper part of the dividing block 32, and the upper part of the bulldozer 323 is an inclined structure that gradually tilts upward from right to left. As a result, as the bulldozer 323 moves synchronously with the dividing block 32, a part of the soil on the upper part of the dividing block 32 continues to be pushed upward along the inclined structure of the bulldozer 323, so that the soil pushed upward by the inclined surface of the bulldozer 323 moves to the position of the clearing knife 42, and this part of the soil is turned over and loosened by the rotating clearing knife 42, further increasing the gap under the upper soil layer.

[0055] At the same time, the partition block 32 that moves back and forth drives all the bulldozers 323 to move back and forth. When the partition block 32 moves forward, the partition block 32 drives the lower parts of all the bulldozers 323 to move forward. Since the upper parts of the bulldozers 323 are obstructed by the soil, the upper parts of the bulldozers 323 deflect backward around the hinge axis with the partition block 32. The bulldozers 323 drive the fan-shaped grooves on them to rotate synchronously until the rear side of the fan-shaped grooves abuts against the blocking block 324.

[0056] Then, the partition block 32 drives the inclined bulldozer plate 323 to move forward, so that the bulldozer plate 323 pushes the soil upward through its inclined front side, thereby further increasing the gap under the upper soil layer. Similarly, when the partition block 32 drives the inclined bulldozer plate 323 to move backward, the bulldozer plate 323 pushes the soil upward through its inclined rear side.

[0057] See Figure 6 and Figure 7 In order to further increase the pores in the upper soil layer, the present invention makes the following design: a group of combing grooves 325 are opened on the front and rear sides of the bulldozer 323, each group is composed of a number of combing grooves 325 with different inclination angles, and a number of blocking blocks 326 are fixedly installed inside the combing grooves 325.

[0058] When the bulldozer 323 pushes the upper soil upward through its front and rear sides, the bulldozer 323 continues to move to the right along with the partition block 32, which causes the front and rear sides of the bulldozer 323 and the upper soil to move left and right relative to each other, thereby causing the upper soil to move left along the front and rear sides of the bulldozer 323, and then causing a part of the upper soil to move into the combing groove 325 and move left along the trajectory of the combing groove 325.

[0059] The bulldozer 323 combs the lower part of the upper soil through the combing grooves 325 thereon, and since the inclination angles of the combing grooves 325 in the same group are different, the height positions at which the soil flowing along the combing grooves 325 finally moves out of the combing grooves 325 are different, thereby causing gaps to appear between the soil flowing out of two adjacent combing grooves 325, further increasing the number of gaps.

[0060] At the same time, the soil flowing inside the combing groove 325 is blocked by the blocking block 326 inside the combing groove 325, so that the soil flowing inside the combing groove 325 is slower than the soil moving along the front and rear sides of the bulldozer 323, so that the combing groove 325 pushes the soil to produce additional gaps, further increasing the number of gaps, and reducing the possibility of subsequent upper soil being compacted, resulting in too low a loosening effect on the upper soil.

[0061] See Figure 2 、 Figure 3 、 Figure 6 and Figure 7 The lower side of the block structure of the cutting teeth 33 is chamfered, and a pressing plate 321 is slidably connected to the partition block 32. The sliding direction of the pressing plate 321 is perpendicular to the sliding direction of the cutting teeth 33, and a tension spring is provided between the pressing plate 321 and the partition block 32.

[0062] See Figure 6 and Figure 7 A plurality of wedge-shaped plates 322 are fixedly installed at equal intervals along the front-to-back direction on one side of the pressing plate 321 facing the interior of the partition block 32 , and the wedge-shaped plates 322 correspond to the cutting teeth 33 one by one.

[0063] When the cutting teeth 33 are located on the right side of the dividing block 32, the pressing plate 321 is located at the lower part of the dividing block 32. When the dividing block 32 drives the cutting teeth 33 to move to contact the agglomerated soil, the agglomerated soil is simultaneously located at the lower part of the upper soil layer and the upper part of the lower soil layer. The agglomerated soil is adhered to the lower soil layer and is difficult to be pushed. As a result, the cutting teeth 33 are blocked by the agglomerated soil when cutting the agglomerated soil, and the cutting teeth 33 move to the left relative to the dividing block 32.

[0064] When the cutting tooth 33 moves to the left relative to the dividing block 32, the cutting tooth 33 compresses the coil spring at the corresponding position, so that the compression degree of the coil spring gradually increases, and the elastic force of the coil spring gradually increases synchronously, so that the cutting tooth 33 gradually cuts off the agglomerated soil. At the same time, when the cutting tooth 33 moves to the left relative to the dividing block 32, the chamfered part of the cutting tooth 33 contacts the inclined surface of the wedge plate 322, so that the cutting tooth 33 drives the pressing plate 321 to extend downward from the dividing block 32 by pushing the wedge plate 322 downward, so that the pressing plate 321 presses the surface of the lower soil in the agglomerated soil area, effectively preventing the agglomerated soil from disturbing the lower soil when the agglomerated soil is deflected under the push of the cutting tooth 33.

[0065] Subsequently, the cutting teeth 33 completely cut off the agglomerated soil, and the elastic force of the coil spring pushes the cutting teeth 33 to move to the position where they initially extend out of the partition block 32. Subsequently, the tension spring drives the pressing plate 321 upward to the initial position through its own tension.

[0066] See Figures 1 to 7 In addition, the present invention also provides a method for symbiotic cultivation of mushrooms and plants, and the cultivation method has the following steps: S1. The tractor drives the partition block 32 to the starting position of land preparation through the frame 1. The operator controls the tractor to drive the reclaiming blade 42 to rotate. The rotating shaft 41 drives the cutting teeth 33 to move back and forth through the reciprocating threaded rod 342, and the telescopic section of the extended hydraulic cylinder pushes the supporting frame 2 to move downward.

[0067] S2. The carrier frame 2 drives the cutting teeth 33 and the plowing blade 42 to move downward synchronously. The cutting teeth 33 cut the soil, so that the partition block 32 moves to the junction of the upper soil and the lower soil, and the plowing blade 42 is located above the upper soil, so that the partition block 32 forms a physical isolation barrier. The telescopic section of the hydraulic push rod 314 is extended to drive the cutting teeth 33 to rotate ninety degrees to the right.

[0068] S3. The tractor starts to move to the right, and drives the cutting teeth 33, the partition block 32 and the reclaiming blade 42 to move to the right synchronously, so that the cutting teeth 33 moving back and forth continuously cut the soil on the right, and an isolation zone is formed between the upper soil layer and the lower soil layer through the upper side surface of the tetrahedral structure of the cutting teeth 33 and the partition block 32.

[0069] S4. The bulldozer 323 pushes the soil upward through the inclined structure on its upper part and its front and rear sides to the position of the plowing knife 42, and turns over and loosens this part of the soil through the rotating plowing knife 42. The combing groove 325 creates additional gaps in the upper soil, reducing the possibility of the upper soil being crushed later, resulting in too low a loosening effect on the upper soil, which is conducive to the growth of mycelium.

[0070] S5. After the soil is prepared, the mushrooms and plants are planted together in the soil to form a mycorrhizal relationship between the mushrooms and the plants, thereby assisting the growth of the mushrooms.

[0071] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.

Blocking blocks are fixedly installed at equal intervals along the front-to-back direction on the partition block. The blocking blocks correspond to the fan-shaped grooves one by one.

6. The mushroom and plant symbiotic cultivation device according to claim 5, characterized in that: A group of combing grooves are respectively provided on the front and rear side surfaces of the bulldozer plate, and each group is composed of a number of combing grooves with different inclination angles, and a number of blocking blocks are fixedly installed inside the combing grooves.

7. A method for symbiotic cultivation of mushrooms and plants, using the symbiotic cultivation device of any one of claims 1 to 6, characterized in that: The specific cultivation method steps are as follows: S1. The self-propelled device drives the reclaiming blade to rotate, and the reclaiming blade drives the cutting teeth to move back and forth repeatedly through the drive assembly, and then moves the carrier downward; S2. The carrier drives the cutting teeth located at the bottom of the partition block into the soil, and the partition block is located at the junction of the lower layer and the lower layer of soil, and then the partition block is rotated so that the cutting teeth face the moving direction of the self-propelled device; S3. The self-propelled mobile device drives the reclamation blade and the separator to move synchronously. The cutting teeth cut and layer the soil by reciprocating back and forth, and push the upper layer of soil upward, with less disturbance to the lower layer of soil. S4. The reclaiming blade turns over the upper soil and the soil pushed upward by the cutting teeth, thereby loosening the upper soil with minimal disturbance of the lower soil; S5. After the soil is prepared, the mushrooms and plants are planted together in the soil to form a mycorrhizal relationship between the mushrooms and the plants, thereby assisting the growth of the mushrooms.
