Description

Technical Field

[0001] This invention relates to a sand barrier planting machine, specifically a self-propelled tracked sand barrier planting machine, belonging to the field of sand barrier planting technology. Background Technology

[0002] my country has a vast area of ​​desertified land, making windbreak and sand-fixing projects a challenging task. Among these, laying shrub and willow sand barriers is one of the key technologies for controlling shifting sands. However, current sand barrier planting operations still heavily rely on manual labor, resulting in prominent problems such as high labor intensity, low work efficiency, and inconsistent planting quality.

[0003] Although some sand planting machinery has appeared on the market, such as the fully automatic integrated intelligent sand planting machine disclosed in the authorization announcement number CN220326427U, which uses water flow erosion to form planting pits in the sand to avoid the loss of sand moisture, this method is mainly suitable for planting seedlings with roots. For branch-type sand barriers that require direct planting, its clamping and fixing mechanism is difficult to effectively grasp irregularly shaped shrub branches, and branches are prone to slipping or shifting during transportation, resulting in insufficient planting verticality. Another example is the process-oriented multi-threaded seedling planting equipment for desertified land disclosed in the publication number CN119837006A. Although it achieves multi-threaded operation through automated rotating seed hopper and pneumatic seedling planting device and integrates irrigation function, the walking mechanism of its tracked mobile trolley has a fixed grounding shape. When facing the soft, sloping and pitted terrain common in sandy land, the tracks are prone to sinking or slipping, resulting in poor passability and difficulty in ensuring continuous and stable operation. Furthermore, the seedling bin design of this equipment is geared towards standardized seedlings, lacking an effective separation and directional supply mechanism for branches of varying lengths and shapes in sand barriers. This leads to entanglement during material handling, requiring frequent manual intervention and failing to meet the automated material supply requirements of large-scale sand barrier projects. In existing technologies, the power systems of sand barrier planting machines mostly rely on a single fuel or grid power supply mode. In desert areas far from the power grid, fuel refueling is difficult and costly, and exhaust emissions do not meet the environmental protection requirements for ecological restoration. Based on this, this application proposes a self-propelled tracked sand barrier planting machine. By optimizing the design of the partition bars and hollow moving plates of the sand barrier storage and retrieval components to stagger the material retrieval, the problems of branch entanglement and single-time material retrieval reliability are solved. The vibration insertion and conical clamping mechanism of the sand barrier planting components improve the consistency and verticality of planting depth. The multi-mode track adjustment wheel of the self-propelled components enhances the equipment's passability and stability on soft, sloping, and uneven sandy land. Combined with a solar hybrid power system, it achieves energy self-sufficiency and low carbon emissions for field operations, thereby comprehensively improving the mechanization level and engineering quality of sand barrier planting. Summary of the Invention

[0004] This invention provides a self-propelled tracked sand barrier planting machine to solve the problems of low mechanization, poor terrain adaptability, and difficulty in automatic branch feeding in sand barrier planting.

[0005] The present invention achieves the above objectives through the following technical solution: a self-propelled tracked sand barrier planting machine, comprising a frame assembly, the frame assembly comprising a support frame and a base plate, and a sand barrier storage and retrieval assembly, a sand barrier planting assembly and a power drive assembly arranged sequentially inside the frame assembly, with a self-propelled assembly connected to both sides of the bottom of the frame assembly.

[0006] The sand barrier access assembly includes a partition bar, a hollow movable plate, and sand barrier clamps. A branch sand barrier is placed between adjacent partition bars. Multiple sand barrier clamps are connected to the side of the hollow movable plate near the partition bar, and the sand barrier clamps are staggered vertically and vertically in correspondence with the partition bars.

[0007] The sand barrier planting component includes a fixed clamp and a movable clamp arranged symmetrically. The movable clamp is movably inserted into the fixed clamp.

[0011] As a further embodiment of the present invention: a handrail is fixedly connected to the tail end of the base plate along the direction of travel, and an operation control box is fixedly connected to the frame of the handrail. The operation control box is signal connected to each electrical drive component of the sand barrier planting machine.

[0012] As a further embodiment of the present invention: multiple partition bars of the sand barrier access component are fixedly connected to the frame of the support frame. The sand barrier access component also includes a sand barrier base, which is located directly below the partition bars. Several inclined bottom grooves are provided on the sand barrier base. The gaps between the inclined bottom grooves and the adjacent two partition bars are set one by one. The bottom of the inclined bottom grooves slopes upward along the arrangement order of the branch sand barriers.

[0013] As a further embodiment of the present invention: the two ends of the hollow movable plate are provided with hydraulic material picking slide rails, the slide rail body of the hydraulic material picking slide rail is fixedly connected to the support frame, and the slide rail body of the hydraulic material picking slide rail is inclined upward along the arrangement order of the branches and sand barriers.

[0014] The slider of the hydraulic material handling slide rail is fixedly connected to both ends of the hollow moving plate. The sand barrier clamp plate has a positioning groove, and a clamping bladder is fixedly connected in the positioning groove. The clamping bladder is connected to a liquid pipe, and the other end of the liquid pipe is connected to the hollow cavity of the hollow moving plate. The hollow cavity of the hollow moving plate is filled with hydraulic oil.

[0015] As a further embodiment of the present invention: a vibration motor is fixedly connected to the fixed clamp plate of the sand barrier planting component, and vertically arranged sand barrier planting slide rails are fixedly connected to both sides of the U-shaped side support plate. The sliders of the sand barrier planting slide rails are respectively fixedly connected to the ends of the fixed clamp plate. The gaps between the clamping grooves opened on the movable clamp plate and the adjacent sand barrier clamp plates are set one by one. The inner side of the conical clamp connected to each clamping groove is provided with a friction surface.

[0016] As a further embodiment of the present invention: a clamping plate mounting groove is provided in the plate of the fixed clamping plate, the movable clamping plate is movably inserted into the clamping plate mounting groove, a plurality of limiting rods are fixedly connected in the groove of the clamping plate mounting groove, a limiting groove is provided on one side of the movable clamping plate located in the clamping plate mounting groove, the rod of the limiting rod is movably inserted into the limiting groove, a stop block is fixedly connected to one end of the limiting rod located in the limiting groove, a return spring is sleeved on the rod of the limiting rod located in the limiting groove, and the return spring abuts against the front end wall of the limiting groove and the stop block.

[0017] As a further embodiment of the present invention, the self-propelled component also includes a roller support frame, which is disposed on both sides of the roller.

[0018] As a further embodiment of the present invention: a support plate is fixedly connected to one end of the roller support frame near the adjusting wheel, and two hydraulic telescopic rods are fixedly connected to the plate body. The movable end of the hydraulic telescopic rod is connected to the wheel seat, and the two adjusting wheels are rotatably connected to the wheel seat respectively.

[0019] The beneficial effects of this invention are:

[0020] 1. The present invention is provided with a frame assembly, a sand barrier storage and retrieval assembly, a sand barrier planting assembly, a power drive assembly, and a self-propelled assembly. By integrating the sand barrier storage and retrieval assembly, the sand barrier planting assembly, and the power drive assembly on the frame assembly, it is possible to store a large number of branch sand barriers on the sand barrier storage and retrieval assembly, and to transfer the branch sand barriers to the sand barrier planting assembly through the sand barrier storage and retrieval assembly, so that the branch sand barriers can be planted in the sand through the sand barrier planting assembly, thereby realizing the continuous automated operation of the sand barrier planting machine. The self-propelled assembly makes the sand barrier planting machine easy to move in the sand.

[0021] 2. The sand barrier storage and retrieval component of this invention includes a dividing bar, a hollow movable plate, and a sand barrier clamp. The sand barrier clamp and the dividing bar are staggered vertically in a one-to-one correspondence. The dividing bar can physically separate a large number of branch sand barriers, fundamentally avoiding the entanglement problem commonly encountered in manual operation. The hollow movable plate and the sand barrier clamp connected to it are staggered vertically with the dividing bar to form an interlaced retrieval mechanism. When the sand barrier clamp moves, it can accurately grab the outermost single branch or bundle of branch sand barriers from the gap between the dividing bars without interfering with other branch sand barriers in the inner layer.

[0022] 3. The sand barrier planting component of this invention includes a fixed clamp and a movable clamp arranged symmetrically. The movable clamp has a clamping groove on the opposite side, and a conical clamp is connected below the clamping groove. The symmetrical arrangement of the fixed clamp and the movable clamp constitutes an openable clamping mechanism. The movable clamp can move within the fixed clamp, so that the clamping force can be precisely controlled. It can firmly grasp the sand barrier while avoiding damage to the fragile branches of the sand barrier due to excessive clamping force. The clamping groove and the conical clamp further increase the clamping force on the branches of the sand barrier, and the conical clamp helps to guide the tip of the sand barrier to penetrate into the sand, preventing the sand barrier from slipping off during the vibration and insertion process.

[0023] 4. The self-propelled component of this invention includes rollers, a drive belt, and adjusting wheels. Two adjusting wheels are arranged vertically. The front end of the drive belt in the direction of travel has three belt body modes—vertical, upward tilting, and downward tilting—through the change in the position of the two adjusting wheels. By changing the position of the two adjusting wheels, the ground contact state of the front end of the drive belt can be dynamically switched between the three modes. The vertical belt body mode is suitable for flat sandy terrain, ensuring travel stability and low ground contact pressure, and preventing sinking. The upward tilting belt body mode is equivalent to increasing the ground contact angle and length of the front of the track when climbing slopes, improving climbing ability and traction, and effectively preventing backward slippage. The downward tilting belt body mode can make contact with obstacles or ditch edges in advance when facing potholes or downhill terrain, reducing the risk of the planter getting stuck.

[0038] 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.

[0039] Example 1

[0040] like Figures 1 to 13 As shown, a self-propelled tracked sand barrier planting machine includes a frame assembly 1, which includes a support frame 11 and a base plate 13. A sand barrier storage and retrieval assembly 2, a sand barrier planting assembly 3, and a power drive assembly are sequentially arranged inside the frame assembly 1. Self-propelled components 4 are connected to the bottom two sides of the frame assembly 1. By integrating the sand barrier storage and retrieval assembly 2, the sand barrier planting assembly 3, and the power drive assembly on the frame assembly 1, it is possible to store a large number of branch sand barriers on the sand barrier storage and retrieval assembly 2 and to move the branch sand barriers to the sand barrier planting assembly 3 through the sand barrier storage and retrieval assembly 2, so that the branch sand barriers can be planted in the sand through the sand barrier planting assembly 3. This enables the continuous automated operation of the sand barrier planting machine. The self-propelled components 4 facilitate the movement of the sand barrier planting machine in the sand.

[0041] The sand barrier storage and retrieval component 2 includes a partition bar 21, a hollow movable plate 23, and sand barrier clamps 24. Branch sand barriers are placed between adjacent partition bars 21. Multiple sand barrier clamps 24 are connected to the side of the hollow movable plate 23 near the partition bar 21. The sand barrier clamps 24 are staggered vertically to the partition bars 21 in a one-to-one correspondence. The partition bars 21 can physically separate a large number of branch sand barriers, fundamentally avoiding the entanglement problem commonly encountered in manual operation. The staggered vertical arrangement of the hollow movable plate 23 and the sand barrier clamps 24 connected to it with the partition bars 21 forms an interlaced retrieval mechanism. When the sand barrier clamps 24 move, they can accurately grab the outermost single branch or bundle of branch sand barriers from the gaps between the partition bars 21 without interfering with other branch sand barriers in the inner layers.

[0042] The sand barrier planting component 3 includes a fixed clamping plate 31 and a movable clamping plate 32 arranged symmetrically. The movable clamping plate 32 is movably inserted into the fixed clamping plate 31. Several clamping grooves 35 are opened on the opposite sides of the movable clamping plate 32. A conical clamp 36 is connected below the clamping grooves 35. The symmetrical arrangement of the fixed clamping plate 31 and the movable clamping plate 32 constitutes an openable clamping mechanism. The movable clamping plate 32 can move within the fixed clamping plate 31, so that the clamping force can be precisely controlled. It can firmly grasp the sand barrier while avoiding damage to the fragile branches of the sand barrier due to excessive clamping force. The clamping grooves 35 and the conical clamp 36 further increase the clamping force on the branches of the sand barrier. The conical clamp 36 helps to guide the tip of the sand barrier to penetrate into the sand and prevents the sand barrier from slipping off during the vibration and insertion process.

[0043] The self-propelled component 4 includes rollers 41, a drive belt 42, and adjusting rollers 47. The drive belt 42 is wound around the rollers 41 and the adjusting rollers 47. There are two adjusting rollers 47 arranged vertically. The front end of the drive belt 42 can have three belt body modes—vertical, upward tilted, and downward tilted—by changing the position of the two adjusting rollers 47. By changing the position of the two adjusting rollers 47, the ground contact state of the front end of the drive belt 42 can be dynamically switched between the three modes. The vertical belt body mode is suitable for flat sandy terrain, ensuring travel stability and low ground pressure, and preventing sinking. The upward tilted belt body mode is equivalent to increasing the ground contact angle and length of the front of the track when climbing slopes, improving climbing ability and traction, and effectively preventing backward slippage. The downward tilted belt body mode can make contact with obstacles or ditch edges in advance when facing potholes or downhill terrain, reducing the risk of the planter getting stuck.

[0044] Example 2

[0045] Improvements based on Example 1:

[0046] like Figure 1 and Figure 2As shown, the support frame 11 of the frame assembly 1 is connected to a sand-proof net 12. A sand barrier groove 14 is formed in the middle of the base plate 13 of the frame assembly 1 along the direction of movement. A U-shaped side support plate 15 is also fixedly connected between the support frame 11 and the base plate 13. The sand barrier planting component 3 is connected to the U-shaped side support plates 15 at both ends, and is located directly above the sand barrier groove 14. The sand-proof net 12 forms a physical barrier, preventing fine sand and dust from entering the interior of the frame assembly 1 and reducing... To reduce failure rate and maintenance frequency, the sand barrier slot 14 on the base plate 13 provides a dedicated and controlled path for the branch sand barrier, ensuring that the sand barrier held by the sand barrier planting component 3 can pass through the base plate 13 vertically and without interference, and be accurately inserted into the sand at the predetermined position. The U-shaped side support plate 15 connects the upper support frame 11 and the lower base plate 13 into a sturdy frame structure, providing a high-rigidity installation support for the sand barrier planting component 3, ensuring that the force application point of the planting action is stable and reliable.

[0047] Furthermore, a power drive assembly is located on one side of the sand barrier planting assembly 3. The power drive assembly includes a solar panel 16, a generator 19, a battery 110, and a hydraulic pump station 111. The solar panel 16 is fixedly connected to the upper end of the support frame 11. The generator 19, battery 110, and hydraulic pump station 111 are all fixedly connected to the base plate 13. The solar panel 16 and generator 19 are electrically connected to the battery 110. The battery 110 is electrically connected to each electrical drive component of the sand barrier planting machine. The hydraulic pump station 111 supplies power to each electrical drive component of the sand barrier planting machine. The pneumatic drive components provide the driving force, and the solar panel 16 converts solar energy into electrical energy, achieving partial energy self-sufficiency. The generator 19, battery 110, and hydraulic pump station 111 are centrally arranged on the base plate 13, lowering the overall center of gravity and improving the stability of the sand barrier planter during movement and operation. The generator 19 and solar panel 16 can jointly charge the battery 110. Solar energy is used preferentially on sunny days, and the generator 19 can supplement it on cloudy days or under high load, ensuring the continuity and reliability of power supply. The battery 110 also serves as an energy storage unit for sand barrier planting. The machine's various electrical drive components are powered, while the hydraulic pump station 111 converts the electrical energy provided by the battery 110 into hydraulic energy, providing hydraulic driving force to the various electrical drive components of the sand barrier planting machine. This ensures that the sand barrier access component 2 can obtain the required clamping force and moving driving force, and that the sand barrier planting component 3 can obtain the required downward insertion force and clamping force. It should be noted that the solar panel 16 uses a monocrystalline silicon photoelectric conversion module, whose 22% conversion efficiency can ensure an output of 850W peak power under standard lighting conditions, through maximum power point tracking technology. The generator 19 continuously charges the storage battery 110; it uses frequency conversion control technology to ensure that it always operates in the optimal fuel efficiency range, forming a day-night complementary power supply combination with the solar panel 16; the storage battery 110 uses a deep-cycle gel battery pack, and its 200Ah capacity design can support the equipment to work continuously for 4-6 hours, with overcharge and over-discharge protection, extending the cycle life to more than 1500 cycles; the hydraulic pump station 111 integrates a variable pump and an accumulator, automatically adjusting the output flow according to the load demand, and providing an adjustable pressure of 0-15MPa for the hydraulic material handling slide rail 25.

[0048] Furthermore, a handrail 17 is fixedly connected to the rear end of the base plate 13 along the direction of travel. A work control box 18 is fixedly connected to the frame of the handrail 17. The work control box 18 is connected to the electrical drive components of the sand barrier planter. The handrail 17 allows the operator to directly guide the sand barrier planter's movement. The work control box 18, fixed to the handrail 17, facilitates real-time monitoring and intervention of the entire planting process by the operator. The operator can send command signals via buttons, switches, or a touchscreen on the work control box 18, such as: starting or pausing the material retrieval cycle of the sand barrier storage component 2; controlling the insertion depth of the sand barrier planting component 3 and the start / stop of the vibration motor 33; and adjusting the travel speed of the self-propelled component 4. The machine features adjustable angle and direction, and three belt modes for switching the drive belt 42, facilitating operation of the sand barrier planter. It's worth noting that the handle 17 has an ergonomic curved design, with its grip area covered in high-friction rubber, ensuring reliable operation even when wearing gloves. The operation control box 18 integrates a CAN bus communication module, enabling human-machine interaction via waterproof buttons and an LCD display. Its built-in operation mode selection program allows preset planting parameters for flat ground, slopes, and uneven terrain. Control signals are transmitted to each execution unit via shielded twisted-pair cables, with CRC verification ensuring command reliability. The control accuracy of the hydraulic telescopic rod 45 reaches ±0.5mm, enabling precise control of the drive belt 42's shape.

[0049] like Figures 1 to 6 As shown, multiple dividing bars 21 of the sand barrier storage component 2 are fixedly connected to the frame of the support frame 11. The sand barrier storage component 2 also includes a sand barrier base 22, which is located directly below the dividing bars 21. The sand barrier base 22 has several sloping bottom grooves 29, and the gaps between the sloping bottom grooves 29 and adjacent dividing bars 21 are set one-to-one. The bottom of the sloping bottom grooves 29 slopes upward along the arrangement of the branch sand barriers. The multiple dividing bars 21 form a multi-compartment storage space, and each compartment can only hold a limited number of branch sand barriers, realizing the storage of branch sand barriers. The separate placement of the branches avoids the common phenomenon of them getting tangled and intertwined when a large number of branches are piled together. The sand barrier base 22 can support the bottom of the branch sand barrier, and the sloping bottom groove 29 opened on the sand barrier base 22 can ensure that the branch sand barrier can be set at a slight tilt when placed, thereby preventing the branch sand barrier from falling off the storage area due to shaking when moving the sand barrier planting machine. It should be noted that the dividing bar 21 is made of surface-hardened chromium-molybdenum alloy steel, and the dividing bar 21 uses a 5mm diameter and 80mm spacing to form the optimal accommodation space.

[0050] Furthermore, hydraulic material-retrieving slide rails 25 are provided at both ends of the hollow movable plate 23. The slide rail body of the hydraulic material-retrieving slide rail 25 is fixedly connected to the support frame 11, and the slide rail body of the hydraulic material-retrieving slide rail 25 is inclined upward along the arrangement order of the branch sand barrier. This ensures that when the hollow movable plate 23 and the sand barrier clamping plate 24 on it move along the slide rail, their trajectory matches the inclined bottom groove 29 on the sand barrier base 22 and the natural stacking slope of the branch sand barrier. At the same time, when the sand barrier clamping plate 24 clamps out the branch sand barrier, it can make the branch sand... The barrier is clamped out along an upward-sloping path, allowing the bottom end of the branch sand barrier to be suspended above the inclined bottom groove 29, reducing unnecessary interference and resistance, and achieving forward material handling. It should be noted that the hydraulic material handling slide rail 25 preferably adopts the MNL30 series linear hydraulic slide rail. This model of slide rail has a rated load of 300kg and a repeatability of ±0.1mm. In order to achieve synchronous movement of the two slide rails, the two hydraulic material handling slide rails 25 are equipped with HL-20 type flow divider and combiner valves. This valve ensures that the hydraulic cylinders of the two hydraulic material handling slide rails 25 maintain a speed synchronization error of less than 3% within a pressure fluctuation range of ±0.5MPa.

[0051] Furthermore, the slider of the hydraulic material handling slide rail 25 is fixedly connected to both ends of the hollow moving plate 23. The sand barrier clamping plate 24 has a positioning groove 27, and a clamping bladder 26 is fixedly connected in the positioning groove 27. The clamping bladder 26 is connected to a liquid pipe 28, and the other end of the liquid pipe 28 is connected to the hollow cavity of the hollow moving plate 23. The hollow cavity of the hollow moving plate 23 is filled with hydraulic oil. When clamping the branch sand barrier, hydraulic oil is injected into the cavity of the hollow moving plate 23 through the hydraulic pump station 111. The oil pressure is transmitted to all the clamping bladders 26 through the liquid pipe 28, so that the clamping bladders 26... 6. Uniform expansion: The expanded clamping bladder 26 gently wraps around and compresses the sand barrier, adapting well to the irregular shape of the branches. This greatly avoids stress concentration that could damage the bark or buds of the branches, ensuring the activity and integrity of the sand barrier material. At the same time, hydraulic transmission ensures that the clamping bladders 26 on multiple sand barrier clamps 24 can move synchronously with consistent clamping force, ensuring the synchronicity and reliability of the gripping. It should be noted that the clamping bladder 26 is made of polyurethane elastomer material, and its Shore hardness of 35A ensures sufficient clamping force while avoiding damage to the cambium layer.

[0052] like Figure 1 , Figure 2 , Figures 7 to 10As shown, a vibration motor 33 is fixedly connected to the fixed clamping plate 31 of the sand barrier planting component 3. Vertically arranged sand barrier planting slide rails 34 are fixedly connected to both sides of the U-shaped side support plate 15. The sliders of the sand barrier planting slide rails 34 are fixedly connected to the ends of the fixed clamping plate 31. The clamping grooves 35 of the movable clamping plate 32 correspond one-to-one with the gaps between adjacent sand barrier clamping plates 24. Each clamping groove 35 is connected to a conical clamp 36 with a friction surface 37 on its inner side. When the sand barrier planting component 3 clamps the branch sand barrier and inserts it downwards into the sand, the vibration motor 33 generates high-frequency, low-amplitude mechanical vibration. This vibration is transmitted to the branch sand barrier through the fixed clamping plate 31 and the movable clamping plate 32. The vibration greatly reduces the internal friction and cohesion between sand particles, significantly reducing the resistance encountered at the tip of the sand barrier. Furthermore, the vibration helps the sand barrier overcome any hard inclusions or densely packed areas that may exist in the sand. The continuous micro-impacts squeeze or shatter the branches, allowing the sand barrier to be inserted into the preset depth more easily and quickly. The vertical sand barrier planting slide rails 34, which are fixedly connected to both sides of the U-shaped side support plate 15, provide precise vertical guidance for the sand barrier planting component 3, ensuring that the entire planting component can only move in the vertical direction, avoiding lateral swaying or tilting that may occur during the planting process. The gaps between the clamping grooves 35 on the movable clamping plate 32 and the adjacent sand barrier clamping plates 24 are set one-to-one, ensuring that the branches and sand barriers transferred from the sand barrier storage and retrieval component 2 can be accurately received and positioned by the clamping grooves 35 and conical clamps 36 of the sand barrier planting component 3, avoiding the sand barrier from falling or shifting its position during the handover process. It should be noted that the vibration motor 33 is model YZU-10-4, with an excitation force of 10kN and an adjustable frequency range of 30-50Hz. The mechanical vibration generated is transmitted to the branches through the fixed clamping plate 31 to form an axial excitation force. This high-frequency micro-amplitude vibration causes the sand particles to liquefy, reducing the internal friction angle of the sand from 35° to 12° and reducing the insertion and extraction resistance by more than 60%. The sand barrier planting slide rail 34 also preferably uses HGW series hydraulic cylinder guide slide rail. The four sand barrier planting slide rails 34 are powered by a common hydraulic pump station 111. The oil circuit is first divided into two equal parts by a TFA type synchronous valve, and then the two equal parts are divided again by the TFA type synchronous valve to drive the four slide rails on the left and right sides synchronously.

[0053] Furthermore, the fixed clamping plate 31 has a clamping plate mounting groove 312 inside, and the movable clamping plate 32 is movably inserted into the clamping plate mounting groove 312. Several limiting rods 38 are fixedly connected inside the clamping plate mounting groove 312. A limiting groove 39 is opened on one side of the movable clamping plate 32 located inside the clamping plate mounting groove 312. The rod of the limiting rod 38 is movably inserted into the limiting groove 39. A stop block 310 is fixedly connected to one end of the limiting rod 38 located in the limiting groove 39. A return spring 311 is sleeved on the rod of the limiting rod 38 located in the limiting groove 39, and the return spring 311 abuts against the front end wall of the limiting groove 39 and the stop block 310. The clamping plate mounting groove 312 inside the fixed clamping plate 31 provides a constrained sliding space for the movable clamping plate 32, guiding the movable clamping plate 32 to only perform linear reciprocating motion relative to the fixed clamping plate 31. The cooperation between the limiting rod 38 and the limiting groove 39 The sliding stroke of the movable clamp 32 is limited, allowing it to slide freely within a certain range without dislodging from the clamp placement groove 312. When the movable clamp 32 is pushed to close towards the fixed clamp 31 to clamp the sand barrier, the return spring 311 is compressed. When the planting action is completed and the sand barrier needs to be released, the external driving force is removed. At this time, the compressed return spring 311 releases its stored elastic potential energy, pushing the movable clamp 32 to quickly and automatically return to the initial open position along the limiting groove 39, preparing for receiving the next batch of sand barriers. This ensures a fast and continuous planting rhythm without the need for an additional power source to drive the opening action. The return spring 311 also plays a buffering role. At the moment the sand barrier is inserted into the sand, it may encounter hard foreign objects and generate impact. At this time, the elastic deformation of the return spring 311 can absorb some of the impact energy, avoiding damage to the clamp from rigid collisions.

[0054] like Figure 1 , Figure 11 , Figure 12 and Figure 13 As shown, the self-propelled assembly 4 also includes a roller support frame 43, which is disposed on both sides of the roller 41. Multiple rollers 41 are rotatably connected to the roller support frame 43. The frame of the roller support frame 43 is connected to the base plate 13 by a connecting strut 48. The roller support frame 43 provides double-sided support for the roller 41, which can better resist the radial and axial forces on the roller 41 and prevent the roller 41 from tilting when subjected to uneven loads, such as when one side of the track sinks into a sand pit. Multiple rollers 41 jointly support the drive belt 42, so that the drive belt 42 avoids excessive single-point force and sinking too deeply.

[0055] Furthermore, a support plate 44 is fixedly connected to one end of the roller support frame 43 near the adjusting wheel 47. Two hydraulic telescopic rods 45 are fixedly connected to the plate 44. The movable end of the hydraulic telescopic rod 45 is connected to a wheel seat 46. The two adjusting wheels 47 are rotatably connected to the wheel seat 46 respectively. The hydraulic telescopic rod 45 has the characteristics of large output force, precise stroke control, and good self-locking performance. It can generate sufficient thrust or pull to overcome the tension of the drive belt 42 and the ground reaction force, thereby reliably changing the position of the adjusting wheel 47. Position: The rotating wheel seat 46 provides a mounting support for the adjusting rotating wheel 47, ensuring that the adjusting rotating wheel 47 can still rotate freely during position changes. When the two hydraulic telescopic rods 45 extend to the same length, the upper and lower adjusting rotating wheels 47 are set vertically, and the front end of the belt body is vertical. When the two hydraulic telescopic rods 45 extend to different lengths, the front end of the belt body can be tilted upward or downward. It can be pre-adjusted according to the sandy conditions ahead, such as observing slopes, ridges, and potholes, which greatly improves the machine's passability, obstacle-crossing ability, and operating efficiency.

[0056] Working principle: The solar panel 16 and generator 19 store the generated electrical energy in the battery 110 to provide power to the electrical components of the entire sand barrier planting machine. At the same time, the hydraulic pump station 111 converts electrical energy into hydraulic energy to provide power to each hydraulic actuator.

[0057] During operation, the operator starts the equipment through the operation control box 18 on the handrail 17, and the self-propelled component 4 starts to move. The grounding state of the front end of its drive belt 42 can be adjusted by the hydraulic telescopic rod 45 to adjust the position of the two adjusting wheels 47, switching between three modes: vertical, upward tilt and downward tilt, to adapt to different sandy terrains such as flat, uphill or pothole.

[0058] During the movement of the equipment, the sand barrier storage and retrieval component 2 automatically supplies materials. Multiple dividing bars 21 separate and store a large number of branches on the inclined bottom groove 29 of the sand barrier base 22. When the hollow moving plate 23 moves along the inclined trajectory towards the dividing bars 21 under the drive of two sets of hydraulic material picking slide rails 25 that are precisely synchronized by the diversion and collection valves, the sand barrier clamping plate 24 connected to it is inserted into the dividing bars 21 in a staggered manner. Then, hydraulic oil is pressed into the clamping bladder 26 to expand it, thereby simultaneously clamping the outermost single bundle of branches in the sand barrier. After the material is picked up, the hollow moving plate 23 carries the branches backward and is lifted to the area of ​​the sand barrier planting component 3.

[0059] The sand barrier planting assembly 3 begins to operate. Driven by four sand barrier planting slide rails 34 controlled by synchronous valves and equipped with displacement sensor feedback closed loops, the fixed clamping plate 31 moves upward from the bottom of the branch sand barrier. At this time, the movable clamping plate 32 is in an open state under the action of the return spring 311, ready to receive branches. After the branches are accurately placed into the clamping grooves 35 and conical clamps 36 of the movable clamping plate 32, the movable clamping plate 32 closes to the fixed clamping plate 31 under the action of external driving force, overcoming the elastic force of the return spring 311, and firmly clamps the branches through the friction surface 37. Subsequently, the fixed clamping plate 31 is driven downward by the sand barrier planting slide rails 34, so that the branches pass through the sand barrier through slots 14 on the bottom plate 13 and are vertically planted into the sand. At the same time, the vibration motor 33 starts, and the high-frequency vibration generated is transmitted to the branches, effectively reducing the resistance of the sand. The planting depth is precisely controlled by the slide rail stroke.

[0060] After the planting action is completed, the movable clamp 32 automatically resets and opens under the rebound force of the reset spring 311, releasing the branches. The planting component rises and resets, ready for the next work cycle.
