Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and relates to a cutting propagation mechanism suitable for ecological restoration planting, and in particular to a seedling propagation device suitable for desert planting. Background Technology

[0002] In ecological restoration through planting, taking desert willow as an example, the grid-like propagation method involves horizontal and vertical staggered cuttings. Manual cutting is not only hampered by the harsh desert environment and high labor costs, but also slow, inefficient, and yields inconsistent results. While mechanical equipment can reduce labor costs and improve efficiency to some extent, existing willow seedling propagation equipment is complex in structure and cumbersome in process, failing to meet the demands of the current grid-like propagation method. Therefore, it is necessary to propose a new type of seedling propagation equipment suitable for desert planting to overcome these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a novel seedling propagation device suitable for desert planting, which enables rapid seedling propagation of *Salix matsudana*, has a simple and reasonable structure, high propagation efficiency, and good propagation effect, thereby solving the problems existing in the above-mentioned existing *Salix matsudana* seedling propagation devices.

[0004] To achieve the above objectives, the present invention provides the following solution:

[0005] This invention provides a seedling propagation device suitable for desert planting, comprising a frame, a seedling delivery mechanism, a trenching mechanism, and a cutting propagation mechanism, wherein:

[0006] The trenching mechanism and the cutting mechanism are mounted on the frame and are arranged from front to back along the walking direction. The trenching mechanism is used to dig trenches downward to form planting pits, and the cutting mechanism is used to insert seedlings into the planting pits.

[0007] The seedling delivery mechanism is mounted on the frame and is used to deliver seedlings to be propagated to the cutting mechanism.

[0008] In some embodiments, the seedling delivery mechanism is located above the cutting propagation mechanism, and the seedling delivery mechanism includes:

[0009] A seedling storage tray, connected to the frame, is used to store seedlings to be propagated by cuttings; the seedling storage tray is provided with seedling dropping holes, which allow the seedlings on the seedling storage tray to fall down;

[0010] A seedling conveying mechanism 1 is disposed on the seedling storage tray or the frame and located below the seedling dropping hole. The seedling conveying mechanism 1 can receive the seedlings falling from the seedling dropping hole and convey the seedlings downward to the cutting mechanism.

[0011] In some embodiments, the seedling dropping hole is elongated, and the length of the seedling dropping hole is less than the length of the seedling on the seedling storage tray. The seedling dropping hole allows the seedling to be turned to an upright position before falling through the seedling dropping hole.

[0012] In some embodiments, the seedling storage tray is a rectangular flat plate, and the seedling dropping hole is located at one end of the length direction of the rectangular flat plate. The length direction of the seedling dropping hole is parallel to the width direction of the rectangular flat plate, and the length of the seedling dropping hole is less than the width direction of the rectangular flat plate. The first end of the seedling dropping hole abuts against one long side of the rectangular flat plate, and the second end of the seedling dropping hole is spaced apart from the other long side of the rectangular flat plate. The seedlings on the rectangular flat plate are arranged along the width direction of the rectangular flat plate so that when the seedlings reach the seedling dropping hole, they can be flipped to a vertical state with the second end of the seedling dropping hole as a fulcrum.

[0013] In some embodiments, downward-extending anti-deviation limiting baffles are provided below the two long sides of the seedling dropping hole, and a guide channel for the seedling to fall vertically is formed between the two anti-deviation limiting baffles. The guide channel is located above the seedling conveying mechanism.

[0014] In some embodiments, the seedling conveying mechanism includes:

[0015] Conveying gear one and conveying gear two, at least one of which is connected to the frame via a moving mechanism, the moving mechanism being able to drive conveying gear one and conveying gear two to move closer to each other to clamp the sapling, or to move further apart to wait for the sapling to fall;

[0016] A gear drive is mounted on the frame. The gear drive can drive the first conveying gear and the second conveying gear to rotate synchronously and in opposite directions, so that when the first conveying gear and the second conveying gear clamp the seedling, the seedling is vertically transported downward to the cutting mechanism.

[0017] In some embodiments, the gear drive includes a first drive motor and a second drive motor;

[0018] The first conveying gear is rotatably mounted on the frame, and the first drive motor is disposed on the frame and connected to the first conveying gear. The first drive motor is used to drive the first conveying gear to rotate.

[0019] The moving mechanism includes a sliding drive, a sliding track, and a slider that slides along the sliding track. The sliding track is mounted on the frame. The second conveying gear is connected to the slider via a mounting bracket. The second conveying gear is rotatably connected to the mounting bracket and is located on one side of the first conveying gear. The second drive motor is mounted on the mounting bracket and connected to the second conveying gear. The second drive motor is used to drive the second conveying gear to rotate. The sliding drive is mounted on the frame and is used to drive the slider to move along the sliding track so that the first conveying gear and the second conveying gear move closer to or further away from each other.

[0020] In some embodiments, the seedling propagation device suitable for desert planting further includes a seedling drop sensor and a control system. The seedling drop sensor is disposed on at least one of the frame, the seedling delivery mechanism, the trenching mechanism, and the cutting mechanism. Both the seedling conveying mechanism and the seedling drop sensor are communicatively connected to the control system. The seedling drop sensor is used to monitor whether a seedling is falling from the seedling drop hole. When the seedling drop sensor detects that a seedling is falling from the seedling drop hole, the control system can control the seedling conveying mechanism to receive the seedling falling from the seedling drop hole and transport the seedling downward to the cutting mechanism.

[0021] In some embodiments, the cutting mechanism includes:

[0022] A seedling guide pipe is installed on the frame, with the inlet facing upwards and the outlet facing downwards;

[0023] The second seedling conveying mechanism includes a third conveying gear, a fourth conveying gear, and a second gear drive. The third and fourth conveying gears are arranged side by side on the seedling guide pipe and are rotatably connected to the seedling guide pipe. The third and fourth conveying gears are located between the inlet and outlet of the seedling guide pipe. The second gear drive is arranged on the seedling guide pipe and can drive the third and fourth conveying gears to rotate synchronously and in opposite directions to convey the seedlings entering the seedling guide pipe downwards into the planting pit to complete the seedling propagation.

[0024] In some embodiments, the trenching mechanism includes a lifting drive and a digging auger configured with a rotary drive, wherein:

[0025] The drilling auger is connected to the lifting drive and is vertically downward;

[0026] The lifting drive is mounted on the frame and is used to drive the digging auger to descend relative to the frame to dig a trench to form the planting pit, or to rise to wait for the next trenching operation.

[0027] The present invention achieves the following technical effects compared to the prior art:

[0028] The seedling propagation and cutting device disclosed in this invention, suitable for desert planting, has a reasonable structural design. Through the integrated design of the seedling delivery mechanism, the trenching mechanism, and the cutting mechanism, it can realize a series of continuous automatic cutting operations, including trenching, seedling delivery, and cutting. This achieves automation of seedling cutting, and the entire structure is simple, lightweight, and low in manufacturing cost. It not only has good cutting effect but also high mobility and fast cutting speed, ensuring planting efficiency. It can work under high intensity in complex environments for a long time, thus solving the problems of existing sand willow grid cutting robots, such as complex structure, low cutting efficiency, and poor cutting effect.

[0029] Furthermore, the seedling propagation device of this invention, suitable for desert planting, is not limited to the dry or wet state of *Salix psammophila* when rapidly propagating seedlings through cuttings, and is not limited to any plant species; other types of cuttings can also be used.

[0042] 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.

[0043] The purpose of this invention is to provide a novel seedling propagation device suitable for desert planting, which enables rapid seedling propagation of *Salix matsudana*, has a simple and reasonable structure, high propagation efficiency, and good propagation effect, thereby solving the problems existing in current *Salix matsudana* seedling propagation devices.

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] like Figure 1 and Figure 2As shown, this embodiment provides a seedling propagation device 100 suitable for desert planting, including a frame 1, a seedling delivery mechanism 2, a trenching mechanism 3, and a cutting mechanism 4. The trenching mechanism 3 and the cutting mechanism 4 are both mounted on the frame 1 and are arranged from front to back along the walking direction (i.e., the "cutting direction"). The trenching mechanism 3 is used to dig trenches downwards at corresponding positions to form planting pits before cutting. The cutting mechanism 4 is used to insert seedlings 5 ​​into the prepared planting pits. The seedling delivery mechanism 2 is mounted on the frame 1 and preferably located above the cutting mechanism 4. The seedling delivery mechanism 2 is used to transport the seedlings 5 ​​to be cut to the cutting mechanism 4. The above-mentioned seedling propagation and cutting device 100, suitable for desert planting, has a reasonable structural design. Through the integrated design of the seedling delivery mechanism 2, the trenching mechanism 3, and the cutting mechanism 4, it can realize a series of continuous automatic cutting operations, including trenching, seedling delivery, and cutting. It achieves automated seedling cutting, and has a simple structure, high cutting efficiency, and good cutting effect. It can be used for rapid seedling propagation and cutting of sand willow.

[0047] Some feasible implementation methods, such as Figures 1-3 As shown, the preferred seedling delivery mechanism 2 is located above the cutting mechanism 4. The seedling delivery mechanism 2 includes a seedling storage tray 21 and a seedling conveying mechanism 23. The seedling storage tray 21 is connected to the frame 1 and is used to store the seedlings 5 ​​to be cut, such as... Figure 2 and Figure 3 As shown, the seedling 5 is generally placed horizontally on the seedling storage tray 21. The seedling storage tray 21 is provided with seedling dropping holes 22, which allow the seedling 5 on the seedling storage tray 21 to fall down. The seedling conveying mechanism 23 is set on the seedling storage tray 21 or the frame 1, and is located below the seedling dropping holes 22. The seedling conveying mechanism 23 can receive the seedling 5 falling from the seedling dropping holes 22 and convey the seedling 5 vertically downward to the cutting mechanism 4. Taking the cutting of sand willow as an example, its seedlings are generally planted vertically. Therefore, during the seedling delivery process, the seedling 5 is kept vertically downward, which makes it easier for the cutting mechanism 4 to quickly complete the cutting after receiving the seedling, thereby improving the cutting efficiency.

[0048] Some feasible implementation methods, such as Figure 1 and Figure 2 As shown, the aforementioned seedling dropping hole 22 is preferably elongated, and its length in the longitudinal direction is less than the length of the seedling 5 on the seedling storage tray 21. This means that the seedling 5 must be flipped to an inclined or vertical position at the seedling dropping hole 22 before it can pass through. The main function of the seedling dropping hole 22 is to ensure that the seedling 5 is flipped to a vertical position before falling through it. In actual operation, the seedling 5 can be manually pushed into the seedling dropping hole 22, and the seedling 5 and the seedling dropping hole 22 are parallel.

[0049] Some feasible implementation methods, such as Figures 1-3As shown, the aforementioned seedling storage tray 21 is preferably a rectangular flat tray. Seedling holes 22 are located at one end of the rectangular flat tray along its length. The length of the seedling holes 22 is parallel to the width of the rectangular flat tray, and the length of the seedling holes 22 is less than the width of the rectangular flat tray. The first end 221 of the seedling holes 22 abuts against one long side of the rectangular flat tray, and the second end 222 of the seedling holes 22 is spaced apart from the other long side of the rectangular flat tray. The seedlings 5 ​​on the rectangular flat tray are arranged along the rectangular flat tray... The saplings are arranged along the width of the rectangular plate so that when they reach the dropping hole 22, they are parallel or nearly parallel to it. The length of the saplings is generally adapted to the width of the rectangular plate (i.e., the length of the saplings is equal to or slightly shorter than the width of the rectangular plate). By setting a plate edge around the outer perimeter of the rectangular plate, the saplings can be guided and limited by the plate edge to ensure that the saplings are always parallel or nearly parallel to the dropping hole 22 (i.e., along the width of the rectangular plate) when moving on the rectangular plate. By adapting the length of the saplings to the width of the rectangular plate, and setting the length of the dropping hole 22 to be shorter than that of the saplings, and arranging the first end 221 of the dropping hole 22 along its length direction closer to the long side of the rectangular plate, any sapling 5 on the rectangular plate can, when it reaches the dropping hole 22, first flip to a vertical position using the second end 222 of the dropping hole 22 as a fulcrum before falling.

[0050] In some feasible implementations, in order to improve the connectivity between mechanisms and reduce the failure rate of seedling cutting, this embodiment also sets up a seedling drop sensor 6 and a control system in the seedling cutting device 100 suitable for desert planting. The seedling drop sensor 6 is set on at least one of the frame 1, seedling delivery mechanism 2, trenching mechanism 3 and cutting mechanism 4. The seedling conveying mechanism 23 and the seedling drop sensor 6 are both connected to the control system. The seedling drop sensor 6 is used to monitor whether there is a seedling 5 falling from the seedling drop hole 22. When the seedling drop sensor 6 detects that there is a seedling 5 falling from the seedling drop hole 22, the control system can quickly control the seedling conveying mechanism 23 to receive the seedling 5 falling from the seedling drop hole 22 and convey the seedling 5 downward to the cutting mechanism 4, so as to prevent the seedling from falling due to the receiving delay, which would cause seedling waste and reduce the seedling cutting rate.

[0051] In some feasible implementations, the seedling sensor 6 can be an infrared sensor or a camera, and it is generally only set at the seedling hole 22 to monitor in real time whether a seedling has fallen at the seedling hole 22.

[0052] In some feasible implementations, to ensure that the sapling 5 falls vertically along the set path and is received by the cutting mechanism 4, downward-extending anti-deviation limiting baffles 24 are provided below the two long sides of the sapling dropping hole 22, such as... Figure 1 and Figure 2As shown, two anti-deviation limiting baffles 24 are parallel and spaced apart, with the spacing width matching the width of the seedling dropping hole 22. A guide channel 25 is formed between the two anti-deviation limiting baffles 24, allowing the seedling 5 to fall vertically. The guide channel 25 is located above the seedling conveying mechanism 23. It should be noted that the guide channel 25 allows the seedling 5 to flip at the seedling dropping hole 22. As the seedling 5 falls from the seedling dropping hole 22, the two anti-deviation limiting baffles 24 prevent the seedling 5 from deviating towards either side of the seedling dropping hole 22 during its descent. Based on the aforementioned anti-deviation limiting baffles 24, the seedling dropping sensor 6 is preferably located at the bottom edge of the anti-deviation limiting baffles 24 to promptly detect the falling of a seedling 5 within the guide channel 25.

[0053] In some feasible embodiments, the aforementioned seedling conveying mechanism 23 is preferably a gear clamping transmission mechanism, specifically including a conveying gear 231, a conveying gear 232, and a gear drive. At least one of the conveying gear 231 and the conveying gear 232 is connected to the frame 1 via a moving mechanism. The moving mechanism can drive the conveying gear 231 and the conveying gear 232 to move closer together to clamp the seedling 5, or to move away from each other to wait for the seedling 5 to fall. The gear drive is mounted on the frame 1, such as... Figure 1 and Figure 2 As shown, conveying gear 1 231 and conveying gear 232 are arranged side by side, with their axes parallel. Gear drive 1 can drive conveying gear 1 231 and conveying gear 232 to rotate synchronously and in opposite directions, so that when conveying gear 1 231 and conveying gear 232 clamp the seedling 5, the seedling 5 is vertically conveyed downward to the cutting mechanism 4.

[0054] In some feasible implementations, the moving mechanism can directly adopt a linear telescopic drive mechanism such as a cylinder, hydraulic cylinder, or electric slide, or it can adopt a mechanical structure based on a guide rail slider assembly. Specifically, the gear drive includes a drive motor 1 and a drive motor 233. The conveying gear 1 231 is directly rotatably mounted on the frame 1 via bearings. The drive motor 1 is also mounted on the frame 1 and connected to the conveying gear 231. The drive motor 1 is used to drive the conveying gear 231 to rotate. The conveying gear 232 is mounted on the frame 1 via the moving mechanism and is located beside the conveying gear 231. The moving mechanism includes a sliding drive 236, a sliding rail 234, and a slider that slides with the sliding rail 234. 235. The sliding track 234 is mounted on the frame 1. The second conveying gear 232 is connected to the slider 235 via a mounting bracket. The second conveying gear 232 can be rotatably connected to the mounting bracket via bearings. The second drive motor 233 is mounted on the mounting bracket and connected to the second conveying gear 232. The second drive motor 233 is used to drive the second conveying gear 232 to rotate. By setting the speed and output torque direction of the first drive motor and the second drive motor 233, the first conveying gear 231 and the second conveying gear 232 can be controlled to rotate in opposite directions. Figure 2 As shown in the example, conveying gear 231 needs to rotate clockwise, while conveying gear 232 needs to rotate counterclockwise. This ensures that the seedling 5 is conveyed vertically downwards. The aforementioned sliding drive 236 can be a cylinder or a hydraulic cylinder. Its cylinder body is mounted on the frame 1, and the end of the piston rod is connected to the slider 235. By driving the cylinder or hydraulic cylinder to extend and retract, the slider 235 can be driven to move along the sliding track 234, thereby causing the conveying gear 232 to move closer to or away from the conveying gear 231 via the mounting frame. Initially, conveyor gear 1 231 and conveyor gear 232 are kept far apart, with sufficient gap between them for the sapling 5 to pass through. When the sapling 5 passes through the gap between conveyor gear 1 231 and conveyor gear 232, the sliding drive 236 is activated, causing conveyor gear 232 to move closer to conveyor gear 1 231 and clamp the sapling 5 in time. Then, through drive motor 1 and drive motor 233, conveyor gear 1 231 and conveyor gear 232 are driven to rotate respectively, so as to use the friction between the gears and the sapling 5 to convey the sapling 5 downward until the sapling 5 is separated from conveyor gear 1 231 and conveyor gear 232. Then, the sliding drive 236 reverses the drive, causing conveyor gear 232 to move away from conveyor gear 1 231, waiting to clamp the next sapling 5.

[0055] In some feasible implementations, the cutting mechanism 4 includes a seedling guide pipe 41 and a seedling conveying mechanism 2. The seedling guide pipe 41 is set on the frame 1 and located directly below the aforementioned seedling dropping hole 22. The first conveying gear 231 and the second conveying gear 232 are arranged between the seedling guide pipe 41 and the seedling dropping hole 22. The seedling guide pipe 41 is arranged vertically as a whole, with the inlet 411 facing upward and the outlet 412 facing downward, which facilitates the smooth passage of the seedling 5 while maintaining the vertical state of the seedling 5. The second seedling conveying mechanism is preferably a gear clamping transmission mechanism, which specifically includes a third conveying gear 42, a fourth conveying gear, and a second gear drive. The third conveying gear 42 and the fourth conveying gear are arranged side by side on the seedling guide pipe 41, and both the third conveying gear 42 and the fourth conveying gear are rotatably connected to the seedling guide pipe 41 through bearings. The third conveying gear 42 and the fourth conveying gear are preferably embedded in the side wall of the seedling guide pipe 41 and located between the inlet 411 and the outlet 412 of the seedling guide pipe 41. The parts of the third conveying gear 42 and the fourth conveying gear that are close to each other are located inside the seedling guide pipe 41, and the space between the third conveying gear 42 and the fourth conveying gear is used to pass through and convey the seedling 5. The second gear drive is arranged on the seedling guide pipe 41, and the second gear drive can drive the third conveying gear 42 and the fourth conveying gear to rotate synchronously and in opposite directions, so as to convey the seedling 5 that has entered the seedling guide pipe 41 downward into the planting pit to complete the seedling cutting. The rotation mode of the aforementioned conveying gear 3 42 and conveying gear 4 is the same as that of the aforementioned conveying gear 1 231 and conveying gear 2, both of which are used to convey the seedlings 5 ​​downwards. Correspondingly, gear drive 2 is the same as gear drive 1, using a motor assembly, that is, gear drive 2 includes drive motor 3 43 and drive motor 44. Drive motor 3 43 and drive motor 44 are both mounted on the frame 1 and are respectively connected to conveying gear 3 42 and conveying gear 4 to drive conveying gear 3 42 and conveying gear 4 to rotate.

[0056] In some feasible embodiments, the trenching mechanism 3 includes a lifting drive 31 and a digging auger 32 equipped with a rotary drive. The digging auger 32 is connected to the lifting drive 31 and faces vertically downward. The lifting drive 31 is mounted on the frame 1 and is used to drive the digging auger 32 to descend relative to the frame 1 to dig a trench downward to form a planting pit, or to rise to await the next trenching operation. To ensure trenching quality, a guide mechanism is preferably provided between the top non-auger part (such as the outer shell, frame plate, etc.) of the digging auger 32 and the frame 1 to ensure that the digging auger 32 rises and falls vertically, preventing the planting pit from tilting outward. The guide mechanism is preferably a slider rail assembly, specifically including a guide slider and a trenching lifting rail 33, such as... Figures 1-3As shown, the ditching lifting track 33 is vertically installed on the frame 1. A guide slider is installed on the top non-auger part (such as the outer shell or frame plate) of the digging auger 32. The top non-auger part (such as the outer shell or frame plate) of the digging auger 32 slides against the ditching lifting track 33 via the guide slider, guiding and limiting the lifting and lowering of the digging auger 32. The digging auger 32 is a common field digging device, and its auger is generally equipped with its own drive motor. The specific structure and working principle of the digging auger 32 will not be described in detail here.

[0057] The following section uses the example of sand willow cuttings to explain in detail the usage method and operating principle of the above-mentioned seedling cutting device 100 suitable for desert planting:

[0058] When propagating sand willow cuttings, the sand willow seedlings are stored in the seedling storage tray 21 and fall into the seedling dropping hole 22. When the seedling dropping sensor 6 detects the seedling falling, it transmits the signal to the control system. The control system controls the conveying gears 231 and 232 of the seedling conveying mechanism 23 to move closer to each other to clamp the seedling 5 falling from the seedling dropping hole 22. By driving the conveying gears 231 and 232 to rotate, the clamped seedling 5 is conveyed downward to the cutting mechanism 4. The seedling 5 enters the seedling guide pipe 41 through the inlet 411 until it enters between the conveying gears 42 and 4. The seedling 5 can continue to be conveyed downward under the action of the opposing rotation of the conveying gears 42 and 4 until the fallen seedling is inserted into the dug planting hole through the outlet 412, thus completing the cutting. Before cutting, the lifting drive 31 lowers the digging auger 33 via the trenching lifting rail 33 to complete the trenching operation. After trenching is completed, the lifting drive 31 raises the digging auger 33 via the trenching lifting rail 33 to await the next trenching operation. During the cutting operation, if... Figure 3 As shown, the saplings are planted at high speed along the pre-set grid-shaped cutting path, forming a protective belt around the sand willow.

[0059] The aforementioned seedling propagation and cutting device 100, suitable for desert planting, has a simple and novel structure, ingenious design, lightweight structure, and low manufacturing cost. It not only has good cutting effect but also high mobility and fast cutting speed, ensuring planting efficiency. It can work under high intensity in complex environments for a long time, thus solving the problems of complex structure, low cutting efficiency, and poor cutting effect of existing sand willow grid cutting robots.

[0060] This solution includes a 100-unit seedling propagation device suitable for desert planting. When rapidly propagating *Salix matsudana* through cuttings, it is not limited to the dryness or wetness of the *Salix matsudana*, nor is it limited to any plant species; other types of cuttings can also be used. This solution can handle various complex geographical environments and is suitable for cutting propagation in multiple scenarios.

[0061] This solution includes a seedling propagation and cutting device 100 suitable for desert planting, with seedling conveying mechanism one, seedling conveying mechanism two, etc. The power configuration is diverse, not limited to electric, pneumatic, and hydraulic power, etc., and can be changed according to the working environment and working method.

[0062] The seedling propagation equipment 100 in this solution, suitable for desert planting, can adjust the planting spacing according to different operating scenarios to meet different planting needs.

[0063] This solution includes a 100-type seedling and cutting propagation device suitable for desert planting, which can achieve high-speed seedling and cutting propagation, and can be used in various scenarios with unlimited quantities of cuttings, thereby improving the efficiency of cutting propagation.
