Description

Technical Field

[0001] This invention relates to a planting device, specifically a scattered shrub sand barrier planting device, belonging to the field of desertification control machinery technology. Background Technology

[0002] Constructing biological sand barriers using shrubs is a key engineering technology for windbreak and sand fixation, and for ecological restoration. Traditional manual planting methods have inherent drawbacks such as high labor intensity, extremely low work efficiency, and inconsistent planting quality, making them unsuitable for large-scale sand barrier construction projects. Therefore, the development of mechanized planting equipment is imperative.

[0003] In the existing technology, there are various mechanical devices for planting trees or shrubs. For example, a greening shrub planting machine disclosed in CN208144050U includes a trenching shovel, a shrub storage box, and a soil mixing box for covering with soil, which can realize continuous operation of trenching, placing shrubs, and covering with soil. This device is mainly designed for greening seedlings with root balls. Its conveying and placing mechanism is not suitable for handling loose shrub branches of varying lengths, loose shapes, and easy entanglement (such as sand shrubs such as sand willow and caragana). It cannot solve the problems of disorder and accumulation of loose shrubs during the transportation process, and it is even more difficult to ensure that each shrub is planted in the sand with a uniform upright posture. Another example is the integrated grass checkerboard sand willow planting device disclosed in CN117322297A. This device integrates the functions of grass checkerboard laying and sand willow planting. It is equipped with a "sand willow throwing device" consisting of a sand willow storage trough, a feeding chute, and a throwing chute in the sand willow planting section. However, this throwing method is essentially a crude planting approach relying on gravity and inertial propulsion. After leaving the storage trough, the shrub branches are in a completely disordered free-fall state, making it impossible to effectively intervene or correct their posture before planting. This results in the planted shrubs being crooked and lacking uprightness, severely affecting the neatness and sand-fixing effect of the sand barrier. Furthermore, as a natural, non-standardized material, the length, curvature, and branch shape of scattered shrub branches vary greatly, posing a fundamental challenge to mechanized precision planting. Existing general-purpose planting machinery either targets standardized seedlings or uses simple tilting and throwing methods; none of them have been designed with a dedicated mechanism to automatically organize, standardize, and precisely guide the disordered scattered shrub branches into the soil. Summary of the Invention

[0004] This invention provides a device for planting scattered shrubs in a sand barrier, which addresses the technical problem of how to automatically organize and vertically and orderly plant messy, scattered shrub branches during the planting process.

[0005] The present invention achieves the above objectives through the following technical solution: a loose shrub sand barrier planting device, comprising a planting mechanism and a soil covering component arranged sequentially along the planting direction, wherein the planting mechanism includes a transport frame and a conveying component, a guiding component and a material guiding component integrated and connected to the frame. The conveying assembly includes a conveyor belt and a material-picking brush. The conveyor belt has several slots for holding shrub branches. The material-picking brush is inclined and positioned above the conveyor belt. The material-picking brush is driven synchronously with the conveyor belt.

A connecting rod docking seat is fixedly connected to the middle of the frame of the soil covering frame. The first connecting seat is fixedly connected to the transport frame. Two movable connecting rods are rotatably connected between the first connecting seat and the connecting rod docking seat. An adjusting connecting rod is also provided between the first connecting seat and the connecting rod docking seat. One end of the adjusting connecting rod is rotatably connected to the first connecting seat. The other end of the adjusting connecting rod is connected to a stop adjustment plate with multiple stop slots. The connecting rod docking seat and any stop slot of the stop adjustment plate are engaged in a limiting snap-fit ​​connection.

[0014] As a further embodiment of the present invention: a second connecting seat, an upper connecting plate, an L-shaped support plate, and a lower connecting plate are provided between the covering plate and the covering frame.

The connecting parts of the upper connecting plate and the L-shaped support plate and the lower connecting plate and the L-shaped support plate are both provided with arc-shaped connecting grooves. Bolts for locking the connecting parts are threaded into the connecting grooves. A third connecting seat and a compaction wheel connecting rod are provided between the compaction wheel and the covering frame. The third connecting seat is fixedly connected to the frame of the covering frame. The compaction wheel connecting rod is rotatably connected between the compaction wheel and the third connecting seat. An elastic shock-absorbing connecting rod is also connected between the rod of the compaction wheel and the third connecting seat.

[0015] The beneficial effects of this invention are: 1. The present invention is provided with a planting mechanism and a soil covering component arranged sequentially along the planting direction. The planting mechanism includes a transport frame and a conveying component, a guiding component and a material guiding component integrated and connected to the frame. The transport frame provides a stable installation platform for each component, ensuring that the relative position of each component can be maintained accurately when operating in sandy and rugged terrain, avoiding misalignment or failure caused by vibration or impact. The conveying component, guiding component and material guiding component are arranged sequentially along the planting direction to form a continuous and smooth material flow path. The process of conveying, aligning, guiding and finally guiding the shrub branches into the soil is seamlessly connected, which greatly reduces the risk of jamming and congestion in the intermediate links. 2. The conveying component of this invention includes a conveyor belt and a material-pulling brush. The conveyor belt has several slots for holding shrub branches. The material-pulling brush is inclined and positioned above the conveyor belt. The material-pulling brush is driven synchronously with the conveyor belt. The shrub branches conveyed by the conveyor belt are moved to an aligned position at one end by the material-pulling brush. The groove design of the conveyor belt can effectively limit the scattered shrub branches during the conveying process, preventing the branches from rolling, piling up, or tangling on the belt surface. When the material-pulling brush rotates, it can apply a component force along the conveying direction, continuously pulling the branches to one side and gradually adjusting their posture, so that one end of all the branches is aligned at the end of the conveying process, ensuring that they can be planted vertically later. The synchronous drive of the conveyor belt and the material-pulling brush ensures the matching of the two actions, avoiding branch pulling or misalignment caused by speed difference, and realizing dynamic sorting and directional arrangement of shrub branches during the conveying process. 3. The guiding component of this invention includes a guiding planting box, which is folded and rotatably connected to the transport frame. The guiding planting box is located directly below the end of the conveyor belt. The guiding planting box has an inner guide slope inside and a long strip-shaped discharge port at the bottom. The guiding planting box receives the aligned shrub branches that fall from the conveyor belt, realizing the transfer of materials from horizontal transport to vertical guidance. The inner guide slope inside the box can guide the falling branches to slide along the slope and gradually change from an inclined state to an approximately vertical state, avoiding the posture disorder or damage caused by the branches falling directly. The long strip-shaped discharge port at the bottom of the guiding planting box has its long side aligned with the planting direction, so that the branches can enter the planting trench in the correct orientation when leaving the guiding planting box, that is, the length direction of the branches is parallel to the planting row direction. This not only facilitates the subsequent soil covering and compaction operations, but also ensures the uniformity of the rows after planting. 4. The material guiding component of this invention includes an active guide roller and a driven guide roller located directly below the discharge port and rotating in opposite directions. Both the active and driven guide rollers are connected to a spiral guide strip and a material-pushing strip. The material-pushing strip is located in the gap between the spiral guide strips. The spiral direction of the spiral guide strip is consistent with the planting direction. When the branch passes between the two rollers, the spiral guide strip generates an axial propulsive force through contact with the surface of the branch, assisting the branch to move along the planting direction and preventing it from getting stuck at the outlet or retreating. At the same time, the material-pushing strip rotates in the gap, which can agitate the surface of the branch, helping to break up any branches that may be slightly tangled, ensuring that each shrub is guided independently. The design of combining spiral and material-pushing strips provides stable clamping power while also having combing and directional propulsion functions, allowing the shrub branches to be planted in the sand at a controllable speed and in the correct posture.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the 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.

[0019] Example 1 like Figures 1 to 16 As shown, a loose shrub sand barrier planting device includes a planting mechanism and a soil covering component 5 arranged sequentially along the planting direction. The planting mechanism includes a transport frame 1 and a conveying component 2, a guiding component 3, and a material guiding component 4 integrated and connected to the frame. The transport frame 1 provides a stable installation platform for each component, ensuring that the relative position of each component can be maintained accurately when operating in the rugged sandy terrain, avoiding misalignment or failure caused by vibration or impact. The conveying component 2, the guiding component 3, and the material guiding component 4 are arranged sequentially along the planting direction, forming a continuous and smooth material flow path. The process of conveying, aligning, guiding and finally guiding the shrub branches into the soil is seamlessly connected, greatly reducing the risk of jamming and congestion in the intermediate links. The conveying assembly 2 includes a conveyor belt 23 and a material-pulling brush 24. The conveyor belt 23 has several slots for holding shrub branches. The material-pulling brush 24 is inclined and positioned above the conveyor belt 23. The material-pulling brush 24 is driven synchronously with the conveyor belt 23. The shrub branches conveyed by the conveyor belt 23 are moved to an aligned position by the material-pulling brush 24. The grooved design of the conveyor belt 23 can effectively limit the scattered shrub branches during the conveying process, preventing the branches from rolling, piling up, or tangling on the belt surface. When the material-pulling brush 24 rotates, it can apply a component force along the conveying direction, continuously pulling the branches to one side and gradually adjusting their posture, so that one end of all the branches is aligned at the end of the conveying process, ensuring that they can be planted vertically later. The synchronous drive of the conveyor belt 23 and the material-pulling brush 24 ensures the matching of the two actions, avoiding branch pulling or misalignment caused by speed difference, and realizing the dynamic sorting and directional arrangement of shrub branches during the conveying process. The guiding component 3 includes a guiding planting box 31, which is folded and rotatably connected to the transport frame 1. The guiding planting box 31 is located directly below the end of the conveyor belt 23. The guiding planting box 31 has an inner guiding slope 34 inside and an elongated discharge port 35 at its bottom. The guiding planting box 31 receives aligned shrub branches falling from the conveyor belt 23, realizing the transfer of materials from horizontal conveying to vertical guidance. The inner guiding slope 34 inside the box can... The branches are guided to slide along the slope and gradually change from an inclined state to an almost vertical state, avoiding the posture disorder or damage caused by the direct fall of the branches. The long strip-shaped discharge port 35 opened at the bottom of the guide planting box 31 has its long side direction consistent with the planting forward direction, so that the branches can enter the planting trench in the correct direction when leaving the guide planting box 31, that is, the length direction of the branches is parallel to the planting row direction. This not only facilitates the subsequent soil covering and compaction operation, but also ensures the uniformity after the planting rows are formed. The material guiding assembly 4 includes an active guide roller 41 and a driven guide roller 42 located directly below the discharge port 35 and rotating in opposite directions. Both the active guide roller 41 and the driven guide roller 42 are connected to a spiral guide strip 411 and a material-pushing strip 412. The material-pushing strip 412 is located in the gap between the spiral guide strips 411. The spiral direction of the spiral guide strip 411 is consistent with the planting direction. When the branch passes between the two rollers, the spiral guide strip 411 generates an axial propulsive force through contact with the surface of the branch, assisting the branch to move along the planting direction and preventing it from getting stuck at the outlet or retreating. At the same time, the material-pushing strip 412 rotates in the gap, which can pry the surface of the branch, helping to break up any branches that may be slightly tangled, ensuring that each shrub is guided independently. The design of combining spiral and material-pushing strips provides stable clamping power while also having combing and directional propulsion functions, so that the shrub branches can be planted in the sand at a controllable speed and in the correct posture.

[0020] Example 2 Improvements based on Example 1: like Figure 1 , Figure 5 and Figure 6 As shown, rollers 11 are connected to the four corners of the bottom of the transport frame 1. L-shaped brackets 12 are fixedly connected to both sides of the frame of the transport frame 1. An elastic folding frame 32 is connected between the side of the guide planting box 31 away from the conveying component 2 and the transport frame 1. Support legs 33 are fixedly connected to both ends of the guide planting box 31, and the support legs 33 are locked in the L-shaped brackets 12 when the guide planting box 31 is in a vertical position. It should be noted that the elastic folding frame 32 can adopt the horizontal support connecting bracket, vertical support connecting bracket, first support bracket, second support bracket, connecting rod and spring involved in the foldable table legs disclosed in announcement number CN205306281U. The connection relationship and position of the above components are as follows. The relationships between the components are already known and need not be elaborated upon. The L-shaped bracket 12 is connected to a locking screw for clamping and fixing the support leg 33. The roller 11 allows the entire planting device to be easily dragged by a traction device or moved on a flat surface, adapting to rapid transfer between different work areas in a sandy environment. The L-shaped bracket 12, the support leg 33, and the elastic folding frame 32 constitute the flipping and locking mechanism of the guide planting box 31, realizing the rapid fixing and release of the working posture of the guide planting box 31. The cooperation between the support leg 33 and the L-shaped bracket 12 forms a stable support when the guide planting box 31 is in a vertical working position, effectively resisting the lateral force and vibration from the soil during operation, ensuring that the guide planting box 31 does not shake.

[0021] Furthermore, a sloping baffle 36, arranged in an outward inclination, is fixedly connected to the side of the opening of the guide planting box 31 away from the conveying component 2. The inner guide slope 34 inside the guide planting box 31 is located on both sides of the shrub planting path, and the inclination of the inner guide slope 34 on the side of the shrub alignment end is smaller than that on the other side. The long strip of the discharge port 35 is consistent with the planting direction. The sloping baffle 36 can effectively intercept shrub branches falling from the end of the conveyor belt 23, preventing them from falling off the guide due to inertia or collision. The opening of the planting box 31 pops outward to ensure that all materials are guided into the guide path inside the box. The guide inner slope 34 adopts an asymmetrical slope design, which has a good posture correction effect. The gentler slope provides support and guidance for the aligned branch ends, maintaining their aligned state; the steeper slope guides and corrects the other end of the branch, causing the entire branch to rotate quickly to a near-vertical posture. The long strip of the discharge port 35 is consistent with the planting direction, ensuring subsequent row planting, soil covering, and ensuring the uprightness of the shrubs after planting.

[0022] like Figures 1 to 4As shown, the conveying assembly 2 also includes frame 22 fixedly connected to the transport frame 1 and located on both sides of the conveyor belt 23. A drive shaft 218 and a driven shaft 219 are rotatably connected between the frame 22. The conveyor belt 23 is connected between the drive shaft 218 and the driven shaft 219. A reinforcing support plate 221 is also fixedly connected between the frame 22. A tension adjusting roller 220 is provided at the bottom end of the frame 22. The roller of the tension adjusting roller 220 is connected to the conveyor belt 23. Both ends of the roller shaft of the tension adjusting roller 220 are connected to the bottom edges of the two frame 22 respectively via screws, and the tension is adjusted accordingly. The connection position of the adjusting roller 220 at the bottom edge of the frame 22 can be adjusted up and down by rotating the screw. The conveyor belt 23 is connected between the driving shaft 218 and the driven shaft 219 to realize belt drive. The reinforcing support plate 221 increases the connection rigidity between the two frames 22 to prevent relative deformation or outward expansion of the frames when bearing shrub branches and running vibration, thereby ensuring the smooth operation of the conveyor belt 23. The tension adjusting roller 220 can adjust the tension of the conveyor belt 23. The height of the tension adjusting roller 220 can be easily changed by rotating the screw, thereby adjusting the tightness of the conveyor belt 23.

[0023] Furthermore, the top edges of the two frame frames 22 are also connected to a transfer plate 21 and an L-shaped baffle 25. The transfer plate 21 is connected directly above the front end of the conveyor belt 23, and the L-shaped baffle 25 is connected above the middle section of the conveyor belt 23. The two ends of the L-shaped baffle 25 are elastically connected to the frame frames 22. A baffle bar 26 is connected to the frame frame 22 near the alignment end of the shrub branches. The baffle bar 26 is connected in front of the end of the conveyor belt 23. The alignment end of the shrub branches conveyed by the conveyor belt 23 is tilted and falls into the guide planting box 31 by the movement of the baffle bar 26. The transfer plate 21 can pick up the shrubs falling from the storage bin or the manual feeding point. The branches are smoothly guided to the starting end of the conveyor belt 23, ensuring that the branches can smoothly enter the groove of the conveyor belt 23. The L-shaped baffle 25 can press down the shrub branches during the conveying process to prevent them from jumping up, leaving the groove or becoming disordered due to the vibration or bumps of the conveyor belt 23. The baffle 26 can make the aligned end of the shrub branches conveyed by the conveyor belt 23 tilted and fall into the guide planting box 31 by the baffle 26. This makes the entire branch gain an inclined posture at the moment of leaving the conveyor belt 23, so that the branch can slide into the guide planting box 31 and move along the inner inclined surface 34 of the guide, realizing the natural transition of the branch from horizontal conveying to inclined introduction.

[0024] Furthermore, the conveying assembly 2 also includes a drive motor 27 fixedly connected to the transport frame 1. A drive gear 211 is coaxially fixedly connected to the motor shaft of the drive motor 27. A first driven gear 29 located outside the frame 22 is coaxially fixedly connected to the drive shaft 218. A first transmission belt 28 connects the drive gear 211 and the first driven gear 29. An inclined material-feeding rod 212 is rotatably connected between the two frame frames 22. A material-feeding brush 24 is connected to the rod of the material-feeding rod 212. A gearbox 210 is also fixedly connected to the outer side of the frame 22 where the first driven gear 29 is located. A rotating shaft 214 is rotatably connected inside the gearbox 210, and the shaft of the rotating shaft 214 is coaxially fixed. A conical roller 215 and a second driven gear 216 are connected. One end of the material-feeding rod 212, which is inserted into the gearbox 210, is coaxially fixed to the material-feeding roller 213. The conical roller 215 and the material-feeding roller 213 are frictionally mated together. A second transmission belt 217 connects the second driven gear 216 and the first driven gear 29. Driven by a single drive motor 27, the conveyor belt 23 and the material-feeding brush 24 can rotate synchronously. Power is transmitted from the first driven gear 29 to the second driven gear 216 via the second transmission belt 217, driving the rotating shaft 214 and the conical roller 215 to rotate. Then, through friction transmission, the material-feeding roller 213 and the material-feeding rod 212 are driven, ultimately causing the material-feeding brush 24 to rotate. The friction transmission between the conical roller 215 and the material-feeding roller 213 allows for a certain amount of slippage buffering, protecting the material-feeding brush 24 from damage when it encounters accidental jamming.

[0025] like Figure 1 , Figures 7 to 11 As shown, the material guiding assembly 4 also includes a planting motor 43 fixedly connected to the transport frame 1. The motor shaft of the planting motor 43 is coaxially fixedly connected to a motor gear 44. The active guide roller 41 and the driven guide roller 42 are both coaxially fixedly connected to a planting gear 413 at the end near the planting motor 43. A planting chain 45 is meshed between the planting gear 413 connected to the active guide roller 41 and the motor gear 44. The outer side of the planting chain 45 is meshed with the planting gear 413 connected to the driven guide roller 42. By having a planting chain 45 simultaneously mesh with the planting gear 413 on both the active guide roller 41 and the driven guide roller 42, it is ensured that the active guide roller 41 and the driven guide roller 42 rotate synchronously in opposite directions, avoiding twisting, squeezing or slipping of the branches due to speed difference, and ensuring that the branches are smoothly and straightly guided into the soil.

[0026] Furthermore, bearings 46 are coaxially fixedly sleeved on both ends of the active guide roller 41 and the driven guide roller 42. Bearing sleeves 47 are sleeved on the outside of the bearings 46. The bearing sleeves 47 connected to the active guide roller 41 are fixedly connected to the transport frame 1. The bearing sleeves 47 connected to the driven guide roller 42 are fixedly connected to a limit link 48. A limit spring 49 and a limit sleeve 410 are movably sleeved on the rod of the limit link 48. The limit sleeve 410 is fixedly connected to the transport frame 1. The two ends of the limit spring 49 abut against the bearing sleeve 47 and the limit sleeve 410. The bearing sleeves 47 connected to the active guide roller 41 are fixedly connected to the transport frame 1, ensuring that the position of the active guide roller 41 is fixed, serving as a driving reference. The driven guide roller 42 is fixedly connected to the bearing sleeve 47 via a limiting link 48. A limiting spring 49 and a limiting sleeve 410 are movably sleeved on the rod of the limiting link 48. The limiting sleeve 410 is fixedly connected to the transport frame 1. The two ends of the limiting spring 49 abut against the bearing sleeve 47 and the limiting sleeve 410. The limiting spring 49 provides a certain preload, causing the driven guide roller 42 to press against the driving guide roller 41 under normal conditions, forming the necessary clamping force to hold the shrub branches. When the branches between the two rollers are of uneven thickness or have knots, the driven guide roller 42 can compress the limiting spring 49 and move backward, thereby automatically increasing the gap between the rollers and preventing the branches from being clamped too tightly, which could cause damage to the bark or jamming during transport. After the thicker part of the branch has passed, the limiting spring 49 can push the driven guide roller 42 back to its original position, improving the ability of the material guiding assembly 4 to pass through shrub branches of different specifications and irregular shapes, and ensuring that the guiding operation can be completed continuously even when the material size fluctuates.

[0027] like Figure 1 , Figures 12 to 16As shown, a soil covering assembly 5 is provided at the tail end of the transport frame 1 along the planting direction. The soil covering assembly 5 includes a first connecting seat 56, a soil covering frame 53, and symmetrically arranged soil covering discs 54 and symmetrically arranged compaction wheels 55. A connecting rod docking seat 52 is fixedly connected to the middle of the frame of the soil covering frame 53. The first connecting seat 56 is fixedly connected to the transport frame 1. Two movable connecting rods 57 are rotatably connected between the first connecting seat 56 and the connecting rod docking seat 52. An adjusting connecting rod 51 is also provided between the first connecting seat 56 and the connecting rod docking seat 52. One end of the adjusting connecting rod 51 is rotatably connected to the first connecting seat 56, and the other end of the adjusting connecting rod 51 is connected to a multi-section opening. The gear adjustment plate 514 has a gear slot, and the connecting rod docking seat 52 is engaged with any gear slot of the gear adjustment plate 514 in a limiting snap-fit ​​connection. By rotating the two movable connecting rods 57, the soil covering frame 53 can swing relative to the transport frame 1. By changing the snap-fit ​​position of the adjusting connecting rod 51 and different gear slots on the gear adjustment plate 514, the tilt state of the movable connecting rod 57 can be changed, thereby locking different tilt angles of the soil covering frame 53. Users can select the most suitable tilt angle according to the sand texture, humidity and planting depth, so that the soil covering plate 54 cuts into the soil at the best angle to achieve the ideal soil covering depth and backfilling effect. The snap-fit ​​locking operation is simple.

[0028] Furthermore, a second connecting seat 58, an upper connecting plate 59, an L-shaped support plate 510, and a lower connecting plate 515 are provided between the covering plate 54 and the covering frame 53. The second connecting seat 58 is fixedly connected to the frame of the covering frame 53. The upper connecting plate 59 is fixedly connected to the second connecting seat 58. The lower connecting plate 515 is rotatably connected to the back side of the covering plate 54. The upper connecting plate 59 is rotatably connected to the horizontal plate of the L-shaped support plate 510. The joints between the upper connecting plate 59 and the L-shaped support plate 510, and between the lower connecting plate 515 and the L-shaped support plate 510, are also connected. The L-shaped support plate 510 has an arc-shaped docking groove 516 at its joint, and the docking groove 516 is threaded with bolts to lock the joint. The combination of the upper docking plate 59, the L-shaped support plate 510, and the lower docking plate 515 provides each cover plate 54 with multi-degree-of-freedom angle adjustment capability. By loosening the bolts in the docking groove 516, the L-shaped support plate 510 can rotate relative to the upper docking plate 59 and the lower docking plate 515 within the arc-shaped groove range, thereby independently adjusting the lateral inclination angle, i.e., the tilt angle, of the cover plate 54, affecting the cover plate. The soil width and the front and rear inclination angles are the soil entry angles. After adjustment, the bolts are tightened to fix them in place. This allows the workers to adjust the two soil covering discs 54 to form the ideal soil covering ridge according to the actual soil conditions and planting row spacing, ensuring that the sand is effectively backfilled into the planting trench and tightly wraps the roots of the shrubs. A third connecting seat 511 and a compaction wheel connecting rod 512 are provided between the compaction wheel 55 and the soil covering frame 53. The third connecting seat 511 is fixedly connected to the frame of the soil covering frame 53, and the compaction wheel connecting rod 512 is rotatably connected between the compaction wheel 55 and the third connecting seat 511. Between 1 and 2, an elastic damping link 513 is also connected between the body of the compaction wheel link 512 and the third connecting seat 511. It should be noted that the elastic damping link 513 can be an energy-absorbing damping rod disclosed in the announcement number CN222363335U. The elastic damping link 513 can absorb the impact and vibration caused by uneven ground during operation, so that the compaction wheel 55 always maintains good contact with the ground and provides adaptive downward pressure, thereby uniformly compacting the backfilled sand and further stabilizing the planted shrubs.

[0029] Working principle: The transport frame 1 is dragged forward along the planting direction by the traction device under the support of the rollers 11. At the same time, the conveying component 2 starts to work. The drive motor 27 drives the drive shaft 218 through the drive gear 211 and the first transmission belt 28 to drive the conveyor belt 23 to rotate. The conveyor belt 23 has several grooves on its body to support the scattered shrub branches and keep them in an orderly arrangement during the transport process. At the same time, the power of the drive motor 27 is also transmitted to the shaft 214 in the gearbox 210 through the first driven gear 29 and the second transmission belt 217, which drives the conical wheel 215 to rotate. The conical wheel 215 drives the feeding wheel 213 and the feeding rod 212 connected to it through friction transmission, so that the feeding brush 24, which is inclined and installed on the feeding rod 212, rotates synchronously with the conveyor belt 23. The feeding brush 24 continuously pushes the branches so that one end gradually moves closer and aligns. When the branches are transported to the end, the aligned end first contacts the stop bar 26 and is pushed, so that the branches are separated from the conveyor belt 23 in an inclined posture. At this time, the guide planting box 31 of the guide component 3 is in a vertical working state. Its support legs 33 are fixed in the L-shaped card seat 12 and locked by the locking screw. The folding posture is kept stable by the elastic folding frame 32. The branches are first guided into the box and slide along the asymmetrical guide inner slopes 34 on both sides. The gentler side maintains the aligned end state, while the steeper side pushes the other end of the branch to turn quickly, so that the branch gradually turns to a near-vertical posture. Finally, it is discharged from the long strip-shaped discharge port 35 in the same direction as the planting direction. Then the guide component 4 begins to work. The planting motor 43 drives the active guide roller 41 and the driven guide roller 42 to rotate in opposite directions through the motor gear 44 and the planting chain 45. The spiral guide strip 411 on the active guide roller 41 and the material-pulling strip 412 located in the gap between them work together to gently clamp the branches falling from the discharge port 35 and push them along the spiral direction. At the same time, the material-pulling strip 412 combs the surface of the branches to prevent the branches from tangling with each other. Under the guidance of the two rollers, the branches are planted into the pre-opened planting trench at a controllable speed. The soil covering assembly 5 at the rear then operates. The soil covering frame 53 is connected to the first connecting seat 56 on the transport frame 1 via the movable connecting rod 57 and the adjusting connecting rod 51. The adjusting connecting rod 51 is fixed to the connecting rod docking seat 52 by different stop slots on the selector adjustment plate 514, thereby adjusting the overall tilt angle of the soil covering frame 53 to adapt to different soil conditions. The soil covering disc 54 is installed on the soil covering frame 53 through a multi-degree-of-freedom connection mechanism composed of the second connecting seat 58, the upper docking plate 59, the L-shaped support plate 510, and the lower docking plate 515, and is connected by the arc-shaped docking groove 516. The opening and tilt angles of each soil covering disc 54 can be independently adjusted to allow it to cut into the sand at the optimal angle, backfilling the soil on both sides of the planting trench to the roots of the shrub. The compaction wheel 55 that follows is connected to the soil covering frame 53 through the compaction wheel connecting rod 512 and the third connecting seat 511. With the help of the adaptive downward pressure provided by the elastic shock-absorbing connecting rod 513, the backfilled soil is compacted in a flexible and uniform manner, so that the planted shrubs are stable and upright. In the end, the entire process of continuous and automated operation from shrub branch transportation, sorting and alignment, vertical guidance, precise delivery into the soil to soil covering and compaction is realized.
