Description

Technical Field

[0001] This invention relates to the field of agricultural and forestry planting equipment technology, specifically to a planting device for ecological restoration of farmland shelterbelts. Background Technology

[0002] Farmland shelterbelts, as an important component of the agricultural ecosystem, possess key ecological functions such as windbreak and sand fixation, climate regulation, water conservation, and biodiversity protection. They serve as a "green barrier" to ensure agricultural production safety and maintain regional ecological balance, making the construction of farmland shelterbelts an urgent need for sustainable agricultural development. To improve the efficiency of farmland shelterbelt construction, transplanting is often employed, where trees are moved to the vicinity of farmland. To increase the survival rate of the trees during transplanting, the roots are typically accompanied by a root ball formed from the native soil. This root ball encloses the roots, reducing water and nutrient loss during the transplanting process. In the planting process of farmland shelterbelts, transplanting equipment can be used as an aid. Some existing transplanting and planting aids include CN218484324U, which discloses a forestry transplanting machine. This machine has a clamping robotic arm at the front of the frame to pick up plants with soil balls and place them into the planting hole, after which manual labor or a backfill shovel is used to cover the soil. This device uses a robotic arm to replace manual handling, reducing the damage rate of the soil ball, while maintaining the original compact state of the soil ball during the process. CN207151421U discloses a "Green Seedling Transplanting Device for Landscape Construction." This device has a T-shaped slide rail, a lifting screw, and a pair of clamping claws on the base. It can laterally hold the trunk and lift the seedling with its soil ball out of the planting hole as a whole through the screw; it also has anti-sway supports to reduce transportation bumps. It focuses on "stable clamping, level lifting, and no breakage during transport." After the soil ball is removed, it maintains its original compact state without any structural intervention on the internal root system. After planting, the root system still needs to penetrate the dense soil ball on its own.

[0003] In summary, most existing planting aids focus on "root protection," maintaining the short-term stability of the root system's environment through the soil ball—a long-standing standard practice in forestry planting. However, this approach has certain technical drawbacks, neglecting the "sealing" effect of the soil ball after planting. During the excavation process, the soil ball easily forms an interface barrier between the old and new soil, hindering the rapid penetration of new roots into the planting soil. This impedes nutrient exchange between the roots and the external soil, leading to the "soil ball isolation effect" and preventing the rapid establishment of a stable nutrient absorption system. As nutrients within the soil ball are depleted, the plant risks withering and dying, exhibiting a typical "false survival" phenomenon, thus reducing the survival rate of transplanted plants to some extent. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems in the prior art and provide a planting device for ecological restoration of farmland shelterbelts, which can break the "closedness" of the soil ball carried by the plant and sort out the plant's roots to eliminate obstacles to plant root growth.

[0005] This invention provides a planting device for ecological restoration of farmland shelterbelts, including a support frame and a clamp. The clamp is mounted on the support frame and is used to clamp the plants to be planted, so that the plants are in an upright position. The device also includes: The turntable mechanism includes a fixed plate and a turntable. The fixed plate is mounted on a support and has a vertical shaft hole. The turntable is horizontally positioned with the fixed plate and is rotatably connected to the shaft hole. The turntable has a first vertical through hole inside and the root ball of the plant to be planted is inserted into the first through hole. The combing mechanism includes a telescopic mechanism, a comb, and a vibrator. The telescopic mechanism is fixedly connected to a turntable, and the comb is connected to the telescopic mechanism. The telescopic mechanism is used to drive the comb to move radially along the root ball. The comb can be inserted into the side wall of the root ball. When the comb moves relative to the side wall of the root ball, it can comb the roots of the plant while scratching the side wall of the root ball. The vibrator is located on the comb and is used to drive the comb to vibrate. A lifting mechanism is connected to the fixed plate, and the lifting mechanism is used to drive the fixed plate to move in the vertical direction.

[0006] Preferably, the turntable is provided with a first sliding cavity, the telescopic mechanism includes a first piston, the first piston is slidably connected to the first sliding cavity along the radial direction of the soil ball, the toothed comb is hinged to the first piston, the first sliding cavity is connected to a water supply device, the first piston is provided with a second through hole, the toothed comb is provided with a water spray nozzle, the water spray nozzle is connected to the first sliding cavity through the second through hole, and the water spray nozzle is used to spray water onto the soil ball.

[0007] Preferably, the first piston is provided with a second sliding cavity along its own axial direction, and a second piston is slidably connected in the second sliding cavity. The second sliding cavity is connected to the second through hole. The comb is hinged to the second piston. The second piston is provided with a third through hole. The third through hole is connected to the water spray nozzle. When the comb drives the second piston to move to the end of the second sliding cavity away from the comb under the support of the soil ball, the third through hole is connected to the second through hole.

[0008] Preferably, the first sliding cavity is provided with a limiting groove along the axial direction of the first piston, and the first piston is provided with a limiting slider, which is slidably connected in the limiting groove. The limiting slider and the limiting groove are used to prevent the first piston from rotating relative to the turntable about its own axial direction. The second piston is coaxially arranged with the first piston and can rotate about the axial direction of the first piston in the second sliding cavity. The first piston is connected with a coil spring, which is connected to the second piston. The coil spring is used to apply an elastic force around the circumference of the first piston to the second piston.

[0009] Preferably, the third through hole is connected to an arc-shaped valve hole, which is located on the second piston. The third through hole is connected to the second through hole through the arc-shaped valve hole. Under the action of the elastic force of the coil spring, the connection between the arc-shaped valve hole and the second through hole is minimized. When the water flow velocity through the arc-shaped valve hole increases, the water pressure drives the second piston to rotate around the axis of the first piston. The second piston compresses the coil spring, thereby increasing the connection between the arc-shaped valve hole and the second through hole.

[0010] Preferably, a spring is provided in the first sliding cavity, the spring abutting against the first piston, and the spring is used to apply an elastic force to the first piston away from the soil ball.

[0011] Preferably, the second through hole is connected to a one-way valve, which is used for one-way flow from the first slide cavity to the second through hole.

[0012] Preferably, the turntable is provided with a gear ring, and the fixed plate is provided with a power device, which is connected to the gear ring through a gear.

[0013] Preferably, the length of the comb teeth is between 5 cm and 10 cm.

[0014] Preferably, the teeth of the comb are cylindrical.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The planting device for ecological restoration of farmland shelterbelts of the present invention clamps the plants to be planted on the clamps. The lifting mechanism drives the fixed plate to rise to the highest point of the soil ball. The telescopic mechanism drives the comb to move radially towards one side of the soil ball until the comb is inserted into the side wall of the soil ball. The comb is driven to vibrate by the vibrator. Then, the lifting mechanism is controlled to drive the fixed plate to descend. The fixed plate drives the telescopic mechanism and the comb to move downward. The telescopic mechanism is controlled to keep the comb inserted into the side wall of the soil ball, thereby scratching the side wall of the soil ball to expose the plant's basal roots from the soil ball, thereby breaking the "closedness" of the soil ball. Under the action of the comb teeth, the exposed basal roots can be combed and root growth obstacles can be eliminated. When the lifting mechanism drives the comb to the bottom of the root ball, the telescopic mechanism retracts and the lifting mechanism rises to reset the comb. Then, the turntable is rotated, driving the comb to rotate a certain angle around the height of the plant. This process is repeated to break the soil in another area of ​​the root ball. By repeating this process, the entire sidewall of the root ball can be broken and the exposed roots can be combed, promoting the rapid penetration of new roots into the root ball and integration into the planting soil. This avoids the "root ball isolation effect" which can cause large seedlings to "falsely survive" or die.

[0016] Water from the first sliding chamber enters the spray nozzle through the second through-hole on the first piston and is then sprayed out. This water jet softens the root ball, reducing its hardness and facilitating comb engraving, while the impact of the water also breaks up the soil. When the first piston drives the comb to contact the sidewall of the root ball, the supporting force of the sidewall exerts a reaction force towards the first sliding chamber, increasing the water pressure within the chamber and thus enhancing the impact force of the water jet. This further strengthens the soil-breaking efficiency. Furthermore, the rapid spray from the nozzle prevents excessive compression of the root ball by the comb when it contacts the sidewall, thus preventing the root ball from breaking and causing the main root and numerous fibrous roots to fracture, thereby avoiding plant death due to dehydration or infection after transplanting.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figures 1-6 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Unless otherwise defined, the technical or scientific terms used herein should be understood in their ordinary sense by one of ordinary skill in the art to which this invention pertains. Words such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “inner,” “outer,” “upper,” “lower,” “far,” “near,” “front,” and “back” are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0021] like Figures 1-6 As shown, the present invention provides a planting device for ecological restoration of farmland shelterbelts, including a carrier, a support 101, and a clamp 102. The support 101 is mounted on the carrier, and the clamp 102 is mounted on the support 101. The clamp 102 is used to clamp the plant 1 to be planted so that the plant 1 is in a vertical position. It also includes a turntable mechanism, a combing mechanism, and a lifting mechanism 109. The turntable mechanism includes a fixed plate 103 and a turntable 104. The fixed plate 103 is mounted on the support 101 and has a vertically oriented rotating shaft hole. The turntable 104 is horizontally arranged with the fixed plate 103 and is rotatably connected to the rotating shaft hole. The turntable 104 has a vertically oriented first through hole 105, into which the soil ball 108 of the plant 1 to be planted is inserted. 5. The combing mechanism includes a telescopic mechanism 106, a toothed comb 107, and a vibrator 110. The telescopic mechanism 106 is fixedly connected to the turntable 104, and the toothed comb 107 is connected to the telescopic mechanism 106. The telescopic mechanism 106 is used to drive the toothed comb 107 to move radially along the root ball 108. The toothed comb 107 is inserted into the side wall of the root ball 108. When the toothed comb 107 moves relative to the side wall of the root ball 108, it can comb the roots of the plant 1 while marking the side wall of the root ball 108. The vibrator 110 is provided on the toothed comb 107 and is used to drive the toothed comb 107 to vibrate. The lifting mechanism 109 is connected to the fixed plate 103 and is used to drive the fixed plate 103 to move in the vertical direction.

[0022] The working principle of the above embodiments is briefly described below: The core design of this device aims to overcome key technical bottlenecks in traditional farmland shelterbelt transplanting, such as root entanglement and root isolation from the planting soil caused by the "closed" nature of the root ball 108. Through a set of precise and coordinated mechanical actions, it achieves the dual goals of "improving the structure of the root ball 108" and "optimizing root growth," providing core technical support for increasing the survival rate of transplanted plants. Its entire workflow revolves around the technical logic of "stabilization and fixation - mechanism positioning - directional soil breaking - cyclic covering," with each mechanism's actions interconnected, ensuring both operational precision and maximizing the effectiveness of the technological improvements.

[0023] This device is mounted on a dedicated vehicle (agricultural vehicle). The clamp 102 of this device is designed to accommodate plant stems of different thicknesses. In the specific operation, the plant 1 with soil ball 108 to be planted is firmly clamped on the device by the clamp 102 for transfer. The vehicle can be used to transfer the plant, ensuring that the plant 1 remains upright during the transplanting process and avoiding the risk of the soil ball 108 breaking apart due to uneven force caused by tilting.

[0024] The lifting mechanism 109 is activated by the control system, which drives the fixed plate 103 connected to it to rise smoothly until the fixed plate 103 drives the telescopic mechanism 106 and the comb 107 on it to reach the highest point of the soil ball 108. This height setting ensures that the comb 107 can complete the processing of the entire longitudinal range starting from the top of the soil ball 108. Subsequently, the telescopic mechanism 106 is controlled to extend horizontally, and the comb 107 connected to its end will slowly move radially towards the side wall of the soil ball 108 until the comb teeth 9 of the comb 107 are deeply inserted into the side wall of the soil ball 108. Then, the comb 107 is driven to vibrate by the vibrator 110. The vibrating comb 107 ensures that it can effectively scratch the structure of the soil ball 108, while avoiding the soil ball 108 from breaking due to excessive insertion, thus achieving precise control of "breaking without breaking".

[0025] Once the comb 107 is precisely inserted into the root ball 108, the device enters the core stage of breaking the soil and combing the roots. The design of this stage directly reflects the core technical value of the device. The control system synchronously regulates the lifting mechanism 109 and the telescopic mechanism 106. The lifting mechanism 109 drives the fixed plate 103 to move the telescopic mechanism 106 and the comb 107 downwards at a uniform speed, while the telescopic mechanism 106 adjusts the telescopic amount in real time according to the curvature of the side wall of the root ball 108, always maintaining a stable state in which the comb 107 is deeply inserted into the side wall of the root ball 108. During this process, the teeth of the comb 107 will form uniform longitudinal grooves on the side wall of the root ball 108. These grooves not only break the tight structure formed by the root ball 108 after transportation and transplanting in traditional transplanting, but also directly cut off the entanglement nodes of the root packing inside the root ball 108, fully exposing the root packing that was originally wrapped inside the root ball 108. At the same time, the special tooth shape design of the comb played a key role. Its spacing and tooth tip angle were optimized through repeated experiments. While carving the soil ball 108, it can gently and effectively comb the exposed roots, gradually untangle the tangled roots, eliminate the physical obstacles when the roots grow outward, and create favorable space for the sprouting and extension of new roots.

[0026] When the comb 107, driven by the lifting mechanism 109, smoothly moves to the bottom of the root ball 108, the single longitudinal soil breaking and combing action is completed. The device then enters the reset and angle adjustment stage to prepare for full circumferential coverage of the root ball 108. The control system first instructs the telescopic mechanism 106 to retract, driving the comb 107 to slowly pull out from the side wall of the root ball 108, avoiding damage to the root ball 108 structure due to dragging of the comb 107 during the reset process. Subsequently, the lifting mechanism 109 reverses its direction, driving the fixed plate 103 to lift the moving comb 107 back to the initial position at the top of the root ball 108. At this time, the turntable 104 is activated. The linkage structure between the turntable 104 and the fixed plate 103 will drive the comb 107 to rotate around the height of the plant 1 at a certain angle. The rotation angle can be flexibly set according to the diameter of the root ball 108 and the coverage area of ​​the comb 107, usually controlled between 30 and 60 degrees, to ensure that the scoring areas of two adjacent soil breaking operations can be seamlessly connected without any dead corners.

[0027] After the angle adjustment is completed, the device repeats the entire process described above: "Extension mechanism 106 extends - comb 107 inserts - lifting mechanism 109 descends - root combing through soil - extension mechanism 106 retracts - lifting mechanism 109 resets - turntable 104 rotates." Through multiple cyclical operations at different angles, the scoring and combing actions of the comb 107 cover the entire sidewall of the root ball 108. This circumferential treatment method can completely break the "closed" structure of the root ball 108, transforming it from a tightly packed block structure into a porous structure that is "loose on the outside and stable on the inside." This retains the basic protection of the root system within the root ball 108 while creating channels for the roots to penetrate outwards through the scoring. Simultaneously, the combed roots are freed from entanglement and can quickly extend into the surrounding planting soil. After the entire process is completed, the structure of the root ball 108 is optimized, root growth obstacles are eliminated, and the lifting mechanism then lays a solid foundation for the rapid integration of the roots into the planting soil and the establishment of a stable nutrient absorption system after transplanting.

[0028] To verify the effect of this planting device on improving transplant survival rate, a controlled experiment was conducted. The experiment strictly controlled variables, selecting 5-year-old poplar and 8-year-old Scots pine saplings commonly used in farmland shelterbelts as research subjects. This ensured that the control and experimental groups had identical core conditions, including tree age, transplanting environment, and maintenance standards. The control group underwent traditional transplanting (without device treatment), while the experimental group had their root balls and roots treated with the device before transplanting. The comparison of data from the two groups visually demonstrates the device's technological advantages. The experimental results show that the survival rate of both tree species significantly improved after device treatment. Through the synergistic effect of "mechanical soil breaking + root banding," the device precisely solved core problems in traditional transplanting, such as the "root ball isolation effect" and root banding obstruction, improving root growth vitality and environmental adaptability after transplanting. Its effect on improving survival rate is stable.

[0029] The planting device for ecological restoration of farmland shelterbelts of the present invention can break the "closedness" of the soil ball 108 carried by the plant 1 and comb the roots of the plant 1 before transplanting the plant 1 in the shelterbelt, so as to eliminate the obstacles to the root growth of the plant 1, promote the rapid penetration of the new roots of the plant 1 through the soil ball 108 and integrate into the planting soil, and avoid the plant 1 from "false survival" or death due to the "isolation effect of soil ball 108".

[0030] Based on the above embodiments, in order to reduce the hardness of the soil ball 108, facilitate the engraving of the comb 107, and enhance the soil breaking efficiency.

[0031] like Figures 1-6 As shown, the turntable 104 is provided with a first sliding cavity 201, the telescopic mechanism 106 includes a first piston 202, the first piston 202 is slidably connected to the first sliding cavity 201 along the radial direction of the soil ball 108, the toothed comb 107 is hinged to the first piston 202, the first sliding cavity 201 is connected to a water supply device, the first piston 202 is provided with a second through hole 203, the toothed comb 107 is provided with a water spray nozzle 204, the water spray nozzle 204 is connected to the first sliding cavity 201 through the second through hole 203, and the water spray nozzle 204 is used to spray water onto the soil ball 108.

[0032] Water is supplied to the first sliding cavity 201 through a water supply device. The water pressure in the first sliding cavity 201 drives the first piston 202 to move radially toward the side closer to the soil ball 108. The first piston 202 drives the comb 107 to approach the soil ball 108 until the comb 107 is inserted into the side wall of the soil ball 108. Since the comb 107 is hinged to the first piston 202, under the supporting force of the side wall of the soil ball 108, the comb 107 is tangential to the side wall of the soil ball 108, thus ensuring that the comb teeth 9 of the comb 107 can be inserted vertically into the side wall of the soil ball 108. At the same time, the water flow in the first sliding cavity 201 enters the water spray nozzle 204 through the second through hole 203 on the first piston 202, and then sprays out from the water spray nozzle 204. The water jet not only softens the soil ball 108 to reduce its hardness, making it easier for the comb 107 to carve, but the impact of the water flow also breaks the soil. Finally, as the water flow in the first sliding cavity 201 drives the first piston 202 to move closer to the soil ball 108, when the first piston 202 drives the comb 107 to abut against the side wall of the soil ball 108, under the supporting force of the side wall of the soil ball 108, a reaction force is applied to the first piston 202 towards the first sliding cavity 201, thereby increasing the water pressure in the first sliding cavity 201, thereby increasing the impact force of the water flow sprayed from the nozzle 204, further enhancing the soil breaking efficiency of the water flow, and because the water flow is sprayed out quickly from the nozzle 204, it can prevent the comb 107 from excessively squeezing the soil ball 108 when it contacts the side wall of the soil ball 108, thereby preventing the soil ball 108 from breaking and causing the main root and a large number of fibrous roots to break, so as to avoid the plant 1 from dying due to water loss or infection after transplanting.

[0033] As a preferred option, such as Figures 2-6As shown, the first piston 202 is provided with a second sliding cavity 301 along its own axial direction. The second piston 302 is slidably connected in the second sliding cavity 301. The second sliding cavity 301 is connected to the second through hole 203. The toothed comb 107 is hinged to the second piston 302. The second piston 302 is provided with a third through hole 303. The third through hole 303 is connected to the water spray nozzle 204. When the toothed comb 107 drives the second piston 302 to move to the end of the second sliding cavity 301 away from the toothed comb 107 under the support of the soil ball 108, the third through hole 303 is connected to the second through hole 203. When the water supply device fills the first sliding cavity 201 with water, the water flow in the first sliding cavity 201 drives the first piston 202 to move closer to the soil ball 108. At the same time, the water flow in the first sliding cavity 201 enters the second sliding cavity 301 through the second through hole 203. The water flow in the second sliding cavity 301 drives the second piston 302 to move closer to the soil ball 108, that is, away from the first piston 202. This causes the second piston 302 to slide out of the second sliding cavity 301. At this time, the third through hole 303 on the second piston 302 is not connected to the second through hole 203 on the first piston 202. Therefore, the water nozzle 204 will not spray water, thereby preventing the waste of water caused by the comb 107 spraying water when it is not in contact with the soil ball 108. When the comb 107 contacts the soil ball 108, under the supporting force of the soil ball 108, the second piston 302 moves towards the end closer to the first piston 202. When the second piston 302 moves to the end of the second sliding cavity 301 away from the comb 107, the third through hole 303 connects with the second through hole 203. At this time, the comb teeth 9 of the comb 107 are inserted into the side wall of the soil ball 108, and the water nozzle 204 sprays water as the comb 107 is carved.

[0034] As a preferred option, such as Figure 4 and Figure 5As shown, the first sliding cavity 201 is provided with a limiting groove along the axial direction of the first piston 202. A limiting slider 401 is provided on the first piston 202, and the limiting slider 401 is slidably connected within the limiting groove. The limiting slider 401 and the limiting groove prevent the first piston 202 from rotating relative to the turntable 104 around its own axial direction. The second piston 302 is coaxially arranged with the first piston 202 and can rotate around the axial direction of the first piston 202 within the second sliding cavity 301. A coil spring 402 is connected to the first piston 202 and is connected to the second piston 302. The coil spring 402 applies an elastic force around the circumference of the first piston 202 to the second piston 302. During the process of the comb 107 engraving the soil ball 108, the comb teeth 9 of the comb 107 comb the packing. When the comb 107 is subjected to excessive reaction force from the packing, the reaction force will drive the comb 107 to rotate around the axis of the first piston 202. At this time, due to the action of the limiting slider 401 and the limiting groove, the first piston 202 will not rotate. The comb 107 will drive the second piston 302 to rotate relative to the first piston 202. The coil spring 402 is compressed. The elastic force applied by the coil spring 402 to the second piston 302 can prevent the comb 107 from rotating easily when subjected to force, so that the comb teeth 9 of the comb 107 can comb the packing normally. When the force is excessive, the comb 107 can rotate, which can prevent the comb teeth 9 of the comb 107 from applying excessive pulling force to the packing and causing the packing to break, thereby preventing damage to the plant 1.

[0035] As a preferred option, such as Figures 4-6As shown, the third through hole 303 is connected to an arc-shaped valve hole 5, which is located on the second piston 302. The third through hole 303 is connected to the second through hole 203 through the arc-shaped valve hole 5. Under the action of the elastic force of the coil spring 402, the connection between the arc-shaped valve hole 5 and the second through hole 203 is minimal. When the water flow velocity through the arc-shaped valve hole 5 increases, the water pressure drives the second piston 302 to rotate around the axis of the first piston 202. The second piston 302 squeezes the coil spring 402, thereby increasing the connection between the arc-shaped valve hole 5 and the second through hole 203. After the comb teeth 9 of the comb 107 are inserted into the side wall of the soil ball 108, the water supply device is controlled to supply water with reciprocating pressure into the first sliding cavity 201, thereby causing the flow velocity of the water in the arc-shaped valve hole 5 to reciprocate. When the flow velocity of the water in the arc-shaped valve hole 5 increases, the pressure exerted by the water flow on the arc-shaped valve hole 5 will drive the second piston 302 to rotate around the axis of the first piston 202, thereby increasing the connectivity between the arc-shaped valve hole 5 and the second through hole 203. At this time, the second piston 302 will drive the comb 107 to rotate around the axis of the first piston 202, and the coil spring 402 will be compressed by the pressure of the second piston 302. When the water flow velocity in the arc-shaped valve orifice 5 decreases, the pressure exerted by the water flow on the arc-shaped valve orifice 5 decreases. Under the action of the elastic force of the coil spring 402, the second piston 302 rotates in the opposite direction, thereby reducing the connectivity between the arc-shaped valve orifice 5 and the second through hole 203. At this time, the second piston 302 will drive the toothed comb 107 to rotate in the opposite direction around the axis of the first piston 202. With the cooperation of the water supply device and the coil spring 402, the toothed comb 107 can swing back and forth during the process of carving the soil ball 108, thereby improving the soil breaking effect of the toothed comb 107.

[0036] As a preferred option, such as Figures 2-5 As shown, a spring 6 is provided inside the first sliding cavity 201. The spring 6 abuts against the first piston 202, and the spring 6 is used to apply an elastic force to the first piston 202 away from the root ball 108. By providing the spring 6 inside the first sliding cavity 201, the spring 6 applies an elastic force to the first piston 202 away from the root ball 108, which can drive the first piston 202 to retract into the first sliding cavity 201 when clamping the plant 1, thereby preventing the comb 107 and the first piston 202 from affecting the clamping of the plant 1.

[0037] As a preferred option, such as Figure 1 As shown, the second through hole 203 is connected to a one-way valve 7, which is used for one-way flow from the first sliding cavity 201 to the second through hole 203. By setting the one-way valve 7, the water flow sprayed from the nozzle 204 can be prevented from flowing back into the first sliding cavity 201 from the second through hole 203 after impacting the soil ball 108, thus blocking the first sliding cavity 201 and ensuring the normal operation of the device.

[0038] As a preferred option, such as Figures 2-5As shown, the turntable 104 is provided with a gear ring 801, and the fixed plate 103 is provided with a power device 802. The power device 802 is engaged with the gear ring 801 through a gear 803. By providing the power device 802, the power device 802 drives the gear ring 801 to rotate through the gear 803, thereby driving the turntable 104 to rotate relative to the fixed plate 103. This ensures the accuracy of the rotation angle of the turntable 104, thus ensuring that the comb 107 can completely break the soil from the surface of the soil ball 108.

[0039] As a preferred option, such as Figure 3 and Figure 5 As shown, the length of the comb teeth 9 of the comb 107 is between 5 cm and 10 cm. Setting the comb teeth 9 of the comb 107 to 5 cm to 10 cm can prevent the comb 107 from excessively damaging the soil ball 108 while satisfying the requirements of breaking the soil and combing, thereby preventing excessive damage to the soil ball 108 from affecting the normal growth of the plant 1.

[0040] As a preferred option, such as Figure 3 and Figure 5 As shown, the teeth 9 of the comb 107 are cylindrical. Setting the teeth 9 of the comb 107 as cylindrical can reduce the damage to the packing when the comb 107 combs the packing.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
