Description

Technical Field

[0001] This invention relates to the field of planting ecological management technology, and in particular to a willow cutting propagation device and its cutting propagation method. Background Technology

[0002] Currently, one method of desertification control is planting sand willows by cuttings. Multiple sand willows arranged in a grid pattern can effectively stabilize shifting sand. However, to achieve this grid pattern, existing sand willow cuttings are primarily done manually. This is problematic due to the harsh desert environment, high labor costs, low efficiency, and inconsistent cutting results, making it difficult to guarantee the desired grid pattern. Traditional planting equipment, such as tracked and wheeled machines, is limited by their structure, allowing only longitudinal or transverse cuttings, and is unsuitable for the crisscrossing grid method. Therefore, there is an urgent need to design a technical solution that enables grid-pattern sand willow cuttings. Summary of the Invention

[0003] The purpose of this invention is to provide a willow cutting propagation device and method to solve the problems existing in the prior art and to realize the square cutting propagation of willow.

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

[0005] This invention provides a willow cutting propagation device, comprising:

[0008] Preferably, the main frame has a hollow rectangular cross-section, and the transverse and longitudinal movement mechanisms are respectively provided on its two adjacent outer side walls; the main frame can be externally connected to a traction device.

[0009] Preferably, the transverse movement mechanism includes a transverse reciprocating guide rail fixed to one side of the main frame, and the insertion mechanism is slidably disposed on the transverse reciprocating guide rail; the longitudinal movement mechanism includes a longitudinal reciprocating guide rail disposed on the other side of the main frame, and the insertion mechanism is disposed on the longitudinal reciprocating guide rail; both the transverse and longitudinal reciprocating guide rails are provided with a power device, and the power device is capable of driving the corresponding insertion mechanism to reciprocate.

[0010] Preferably, it also includes two sliding guide rods, on which sliders are sleeved. The inner side of the sliders is in contact with the horizontal or vertical reciprocating guide rail, and the insertion mechanism is fixedly connected to the outer side of the sliders.

[0011] Preferably, the cutting mechanism includes a cutting support, which is connected to the transverse or longitudinal movement mechanism; the cutting support is provided with a seedling storage tray, and symmetrical cutting wheels are provided below the bottom opening of the seedling storage tray. The cutting wheels are externally connected to a cutting power mechanism, and the two cutting wheels can clamp and transport the sand willow downwards; a trenching mechanism is provided on one side below the cutting wheels, and the trenching machine can trench the area to be cut.

[0012] Preferably, the cutting propagation power mechanism includes a drive motor, which can control the rotation of the corresponding cutting wheel.

[0013] Preferably, the trenching mechanism includes a vertically arranged drill rod, the top of which is connected to a drill rod drive device, which can drive the drill rod to trench in the area to be planted.

[0014] Preferably, the trenching mechanism further includes a drill frame and a cylinder. The cylinder is vertically fixed on the cutting support, the drill frame is slidably disposed on the lower part of the cutting support, the end of the cylinder rod is connected to the drill frame, and a rotating motor is provided on the drill frame, the rotating motor being drivenly connected to the drill rod.

Detailed Implementation

[0028] 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.

[0029] The purpose of this invention is to provide a willow cutting propagation device and method to solve the problems existing in the prior art and to realize the square cutting propagation of willow.

[0030] 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.

[0031] When propagating sand willow by cuttings, existing equipment can only perform cuttings in a row or column in one direction. However, in desertification control, sand willow generally requires grid-like cuttings, which involves alternating horizontal and vertical cuttings, making existing equipment unsuitable. To solve this problem, this invention provides a sand willow cutting device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a main frame 1 and two insertion mechanisms 4. The main frame 1 has a horizontally arranged transverse mechanism 2 and a longitudinal mechanism 3. The angle between the transverse mechanism 2 and the longitudinal mechanism 3 can be adjusted according to the shape of the main frame 1. In this embodiment, the main frame 1 has a hollow rectangular cross-section. The transverse mechanism 2 and the longitudinal mechanism 3 are respectively provided on its two adjacent outer side walls, so that the transverse mechanism 2 and the longitudinal mechanism 3 are arranged horizontally and vertically. The main frame 1 can be connected to a traction device. In one embodiment, the main frame 1 is hollow inside, and a connecting rod can be used to fix and connect the conveyor wheel inside the main frame 1, so that the main frame 1 can be moved. At the same time, the conveyor wheel will not interfere with the movement of the transverse mechanism 2 and the longitudinal mechanism 3 on the outside of the main frame 1. Two insertion mechanisms 4 are respectively movably mounted on the horizontal movement mechanism 2 and the vertical movement mechanism 3. The insertion mechanisms 4 are used to insert willow branches 7, and the two insertion mechanisms 4 can move horizontally and vertically respectively. After the main frame 1 moves to a certain position, it stops, and then the two insertion mechanisms 4 start to insert willow branches 7. After inserting one, it moves horizontally along the horizontal movement mechanism 2 or the vertical movement mechanism 3 for an interval position, and continues to insert the second willow branch 7, until it moves from one end of the horizontal movement mechanism 2 and the vertical movement mechanism 3 to the other end, thus completing the horizontal and vertical insertion and forming two sides of a virtual square. Then the main frame 1 is moved to the next position, and the above insertion method is repeated. Finally, through horizontal and vertical cross insertion, a square arrangement of willow branches 7 is formed.

[0032] To ensure smoother reciprocating movement of the insertion mechanism 4, the transverse mechanism 2 in this embodiment has a transverse reciprocating guide rail 201 fixed to one side of the main frame 1, on which the insertion mechanism 4 is slidably mounted; the longitudinal mechanism 3 has a longitudinal reciprocating guide rail 301 located on the other side of the main frame 1, on which the insertion mechanism 4 is mounted; both the transverse and longitudinal reciprocating guide rails 201 and 301 are equipped with a power device 5, which can drive the corresponding insertion mechanism 4 to reciprocate. The specific structure of the power device 5 is not limited. In one embodiment, both the transverse and longitudinal reciprocating guide rails 201 and 301 may be equipped with a rack, and the insertion mechanism 4 is equipped with a gear. The gear meshes with the rack, and the gear transmission is connected to a drive motor, so that the drive motor can drive the gear to rotate along the rack, thereby causing the insertion mechanism 4 to reciprocate along the transverse or longitudinal reciprocating guide rail 201 or 301.

[0033] In another embodiment, the power unit 5 can be a lead screw and nut pair, replacing the rack with a lead screw. One end of the lead screw is connected to a lead screw motor, and the nut on the lead screw is connected to the corresponding insertion mechanism 4, which can also achieve the function of driving the insertion mechanism 4 to move back and forth.

[0034] To make the movement of the insertion mechanism 4 smoother, in one embodiment, two additional sliding guide rods 6 are designed. The two sliding guide rods 6 are arranged parallel to the horizontal reciprocating guide rail 201 and the vertical reciprocating guide rail 301, respectively. At the same time, a slider is sleeved on the sliding guide rod 6. The inner side of the slider is in contact with the horizontal reciprocating guide rail 201 or the vertical reciprocating guide rail 301, and the insertion mechanism 4 is fixedly connected to the outer side of the slider. Thus, the power device 5 can be connected to the corresponding slider. By driving the slider to move, the insertion mechanism 4 connected to it will move back and forth. Compared with directly driving the insertion mechanism 4, the introduction of the slider can prevent the insertion mechanism 4 from being subjected to additional pushing force, making the insertion operation more accurate and the reciprocating movement smoother.

[0035] The cutting mechanism 4 in this embodiment includes a cutting support 406, which is fixedly connected to the inner side and the corresponding slider. The top of the cutting support is provided with a funnel-shaped seedling storage tray 401. Below the bottom opening of the seedling storage tray 401, there are symmetrical cutting wheels 403. The cutting wheels 403 are connected to a cutting power mechanism 402. The two cutting wheels 403 can clamp and transport the sand willow 7 downward. A trenching machine 404 is provided on one side below the cutting wheels 403. The trenching machine 404 can trench the area to be cut. The cutting propagation power mechanism 402 is also not limited. In this embodiment, the cutting propagation power mechanism 402 includes a drive motor. The motor shaft of the drive motor is connected to the corresponding cutting wheel 403 and can control the rotation of the corresponding cutting wheel 403. The gap between the two cutting wheels 403 is used for the passage of the willow 7. The gap is small. When the willow 7 passes through, the side wall can contact and connect with the cutting wheel 403. Thus, under the action of friction, the two rotating cutting wheels 403 can drive the willow 7 to move downward and complete the cutting action.

[0036] When the *Salix psammophila* 7 is relatively long, two seedling trays 401 arranged coaxially can be designed to facilitate cutting. Each seedling tray 401 has two symmetrical cutting wheels 403 below the bottom opening. To prevent *Salix psammophila* 7 from tilting during cutting, the axles of the two upper cutting wheels 403 are arranged perpendicularly to the axles of the two lower cutting wheels 403. Thus, the two upper cutting wheels 403 contact the two sides of *Salix psammophila* 7 and transport it downwards. During the process, the two lower cutting wheels 403 contact the other two sides of *Salix psammophila* 7 and work together. In effect, when *Salix psammophila* 7 is being cut downwards, the four cutting wheels 403 can limit the four sides of *Salix psammophila* 7 to prevent it from tilting.

[0037] The trenching machine 404 can adopt structures such as trenching shovels and spiral drills. In this embodiment, the trenching machine 404 includes a drill frame, a cylinder 405, and a vertically arranged drill rod. The cylinder 405 is vertically fixed on the cutting support, and the drill frame is slidably located at the lower part of the cutting support. The end of the cylinder rod of the cylinder 405 is connected to the drill frame. A rotating motor is provided on the drill frame, and the rotating motor is connected to the drill rod for transmission. Thus, the rotating motor drives the drill rod to rotate. During the process, the cylinder 405 drives the drill frame and the drill rod to move downward to complete the drilling trenching operation. The cylinder 405 can also be replaced by a hydraulic cylinder or an oil cylinder. Multiple inclined cutting edges can be arranged around the lower side wall of the drill rod to improve trenching efficiency.

[0038] This invention also provides a method for propagating *Salix matsudana* 7 by cuttings, such as... Figure 3 As shown, Figure 3For the top-down schematic diagram, during the cutting operation, the traction mechanism moves the main frame 1 to the virtual grid, and the trenching machines 404 of the two cutting mechanisms 4 open trenches in the area to be planted in the virtual grid. The *Salix matsudana* 7 is manually dropped vertically from the seedling tray 401 into the space between the two cutting wheels 403. The cutting wheels 403 rotate, pushing the *Salix matsudana* 7 downwards through friction, thus driving the *Salix matsudana* 7 into the trench opened by the trenching machine 404. According to the preset planting spacing between two adjacent *Salix matsudana* 7, the transverse movement mechanism 2 and the longitudinal movement mechanism 3 drive their respective cutting mechanisms 4 to move horizontally to the next area to be planted. Continue trenching and cutting operations in the area until one cutting mechanism 4 moves from one end of the horizontal moving mechanism 2 to the other end, and simultaneously another cutting mechanism 4 moves from one end of the vertical moving mechanism 3 to the other end. At this point, the cutting operation for connecting the horizontal and vertical sides of a virtual square is completed. Then, the traction mechanism moves the main frame 1 to the next virtual square, and the above cutting operation is repeated. At this time, the willow 7 cuttings at the horizontal moving mechanism 2 or the vertical moving mechanism 3 can serve as one of the missing sides of the previous virtual square. Move the main frame 1 in sequence to finally achieve the overall gridded horizontal and vertical cutting operation.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
