Description

Technical Field

[0001] The present invention relates to the technical field of crop planting auxiliary machinery, and particularly to a soil hole-opening device for grape planting. Background Art

[0002] Grape planting occupies an important position in the global agricultural economy. It not only provides high-quality fruits for the fresh grape market but also serves as the core raw material source for the wine industry. The success of grape planting directly affects the yield and quality of the fruits, thereby affecting economic benefits. During the grape planting process, traditional planting methods usually include soil preparation, hole opening, planting, fertilization, and irrigation. Among them, soil hole opening is to provide a suitable growth environment for the roots of grape seedlings.

[0003] Traditional hole-opening devices mostly rely on manual operation or simple mechanical structures. These devices usually consist of manual tools or basic mechanical equipment. Operators need to rely on experience to open holes, which easily leads to unreasonable spacing between grape seedlings. If the spacing is too small, the plants will block and compete for nutrients with each other, affecting the growth and development of the plants. If the spacing is too large, it will cause waste of land resources.

[0004] Therefore, we have developed a new soil hole-opening device for grape planting. Summary of the Invention

[0018] (III) Beneficial effects

[0019] The present invention provides a soil hole opening device for grape planting, which has the following beneficial effects:

[0020] 1. The soil hole-making device for grape planting connects the threaded disk and the roller with a coupling, utilizes threaded transmission to allow the push block to slide in the plane threaded groove as the threaded disk rotates, and pushes the straight plate to drive the brake block to limit the rotation of the roller. In this way, the hole-making position is accurately located according to the number of rotations of the roller, avoiding the unreasonable spacing of seedlings due to insufficient manual experience in traditional hole-making, ensuring plant growth space, and improving fruit yield and quality.

[0021] 2. The soil hole-opening device for grape planting is provided with a steering plate, an L-shaped rod, a compression spring, a threaded rod and a limit plate. The mounting plate is moved upward to drive related components to make the push block disengage from the threaded groove. The compression spring rebound and the threaded rod are used to adjust the moving range of the straight plate, thereby changing the number of rotations of the roller and the threaded disk, thereby achieving flexible adjustment of the distance between adjacent planting holes and improving the practicality of the device.

[0022] 3. The soil hole-opening device for grape planting drives the spiral blade and the inclined soil-throwing plate to rotate through the driving assembly. The spiral blade cuts and transports the soil, and the soil-throwing plate splashes the soil fragments to all sides, thereby preventing the soil fragments from backfilling the planting hole and improving the grape planting hole-opening efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Examples, such as Figure 1 - Figure 5 As shown, the embodiment of the present invention provides a soil hole opening device for grape planting, comprising symmetrically arranged side brackets 1, a mounting plate 2 is slidably matched between the two side brackets 1, a connecting plate 3 is fixedly connected to the bottom of the side bracket 1, a roller 4 is installed at the bottom of the connecting plate 3, a protective cover 5 located on one side of the roller 4 is fixedly installed at the bottom of the connecting plate 3, and a positioning component 6 is installed inside the protective cover 5;

[0031] Specifically, the positioning component 6 includes a threaded disk 7. A planar thread groove 8 is provided on one end face of the threaded disk 7. A push block 9 is slidably fitted in the planar thread groove 8. One side of the push block 9 that fits against the threaded disk 7 is provided with meshing teeth that match the planar thread groove 8, so that the two are meshed with each other. A straight plate 10 is slidably fitted through the peripheral side of the push block 9, and the straight plate 10 is slidably fitted with the protective cover 5. That is, a wire groove for the straight plate 10 to slide is provided on the inner wall of the protective cover 5. While guiding the sliding of the straight plate 10, it also restricts the rotation of the straight plate 10, thereby restricting the rotation of the push block 9. In this way, when the threaded disk 7 starts to rotate, the meshing teeth on the push block 9 will slide along the planar thread groove 8. According to the principle of screw drive, when the planar thread groove 8 rotates, it will push the cooperating push block 9 to move in a straight line in the radial direction, and the push block 9 will push the straight plate 10 to move in the same direction;

[0032] A chute 11 is provided at the top of the straight plate 10. A connecting plate 12 is slidably fitted in the chute 11. A connecting column 21 is fixed to the inner bottom wall of the protective cover 5. The connecting column 21 is rotatably fitted through the connecting plate 12. A brake block 13 is fixedly installed at one end of the connecting plate 12. When the straight plate 10 moves in a straight line in the radial direction, the straight plate 10 will give an oblique thrust to the connecting plate 12 through the chute 11, thereby pushing the connecting plate 12 to rotate around the connecting column 21. At the same time, the connecting plate 12 will drive the brake block 13 at its end to rotate, so that the brake block 13 gradually approaches the outer contour surface of the roller 4. When the brake block 13 is in close contact with the contour surface of the roller 4, according to the principle of friction, that is, when two mutually contacting objects have relative motion or a tendency of relative motion, a force that hinders the relative motion or the tendency of relative motion will be generated on the contact surface. At this time, a frictional force is generated between the brake block 13 and the roller 4 to hinder the rotation of the roller 4;

[0033] A connecting shaft 14 is fixedly installed between the threaded disk 7 and the roller 4. When the hole-opening device moves forward by the rotation of the roller 4, the threaded disk 7 will also rotate following the roller 4. Here, for each rotation of the roller 4, the device will move a certain distance, and this distance depends on the circumference of the roller 4. By recording how many turns the roller 4 has made, it is possible to know how far the device has moved. By combining the seedling spacing, the number of turns of the roller 4 is set, and thus the number of turns of the threaded disk 7 is set. When the threaded disk 7 rotates to the set number of turns, the push block 9 also drives the straight plate 10 to move a sufficient distance in the radial direction. At this time, the connecting plate 12 drives the brake block 13 to be in close contact with the contour surface of the roller 4 to restrict the rotation of the roller 4. At this time, it can be known that the device has reached the hole-opening position and can start hole-opening.

[0034] A steering plate 15 is slidably fitted to an inner side wall of a protective cover 5. A guiding inclined groove 16 is formed through one side of the steering plate 15. A side of a push block 9 away from a threaded disc 7 is fixedly connected with an L-shaped rod 17. The L-shaped rod 17 is slidably fitted to the guiding inclined groove 16. By pulling the steering plate 15 upward, the L-shaped rod 17 can slide along the guiding inclined groove 16. The guiding inclined groove 16 gives an inclined thrust to the L-shaped rod 17, causing the L-shaped rod 17 to move to one side. Thus, the push block 9 is driven by the L-shaped rod 17 to slide relative to a straight plate 10, so that the engaging teeth on the push block 9 gradually disengage from a planar thread groove 8. Similarly, when the steering plate 15 moves downward, the engaging teeth on the push block 9 begin to gradually approach the planar thread groove 8, causing the two to re-enter the engaged state.

[0035] A compression spring 18 is fixedly connected between one end of the straight plate 10 and the other inner side wall of the protective cover 5. When the straight plate 10 moves in the radial direction, the compression spring 18 will be compressed. A threaded rod 19 is threadedly connected through an outer side surface of the protective cover 5. One end of the threaded rod 19 is fixedly connected with a limiting disc 20 located at the other end of the straight plate 10. The movement range of the straight plate 10 is limited by the limiting disc 20, and the movement range of the straight plate 10 can be adjusted by rotating the threaded rod 19. When the engaging teeth on the push block 9 disengage from the planar thread groove 8, the compression spring 18 rebounds to drive the straight plate 10 to move in the reverse direction until the straight plate 10 fits against the limiting disc 20. Subsequently, the steering plate 15 can be pushed downward to make the engaging teeth on the push block 9 re-engage with the planar thread groove 8, thereby adjusting the set number of rotation turns of the threaded disc 7 and the roller 4, and thus adjusting the spacing between adjacent planting holes.

[0036] A guide plate 22 is fixedly connected to the top of the steering plate 15. The guide plate 22 is slidably fitted through the protective cover 5 and the connecting plate 3 in sequence. An adjusting plate 23 is slidably fitted inside a side bracket 1. The adjusting plate 23 is fixedly connected to the guide plate 22. A return spring 24 is fixedly connected between the adjusting plate 23 and the inner top of the side bracket 1. By moving the mounting plate 2 upward, the mounting plate 2 pushes the adjusting plate 23 upward to compress the return spring 24. At the same time, the adjusting plate 23 drives the steering plate 15 to move upward through the guide plate 22. The steering plate 15 drives the L-shaped rod 17 to move to one side through the guiding inclined groove 16, causing the push block 9 to move along with the L-shaped rod 17 until the engaging teeth on the push block 9 disengage from the planar thread groove 8. In this way, the positioning assembly 6 can be prevented from interfering with the normal movement of the device.

[0037] A driving component 25 is fixedly installed on the top of the mounting plate 2. The output end of the driving component 25 is provided with a main body rod 26. A spiral blade 27 is fixedly installed on the circumferential side surface of the main body rod 26. A plurality of soil throwing plates 28 are fixedly connected to the circumferential side surface of the main body rod 26. The soil throwing plates 28 are inclined and installed at a higher position to prevent the soil throwing plates 28 from directly hitting the soil surface during drilling, thereby increasing excessive resistance. The inclined setting can better guide the hitting direction. The driving component 25 drives the main body rod 26 to rotate, and the main body rod 26 drives the spiral blade 27 and the soil throwing plates 28 to rotate synchronously. The spiral blade 27 cuts the soil and conveys the soil upward along the spiral blade 27. At the same time, the soil throwing plates 28 located above start to hit the upward moving soil fragments, causing the soil fragments to splash around and preventing the soil fragments from filling the planting holes again.

[0038] A hydraulic damper 29 located below the mounting plate 2 is fixedly installed inside the side bracket 1. When the device is moving normally, the mounting plate 2 is supported upward by the hydraulic damper 29. At this time, the meshing teeth on the push block 9 are disengaged from the planar thread groove 8. Therefore, when using the positioning function, pressure needs to be applied downward through the handle on the driving component 25, causing the mounting plate 2 to move downward. The return spring 24 starts to rebound and drives the adjusting plate 23 to move downward. The adjusting plate 23 drives the steering plate 15 to move downward through the guide plate 22. The guiding inclined groove 16 gives an inclined thrust to the L-shaped rod 17, causing the L-shaped rod 17 to move to the other side. Thus, the L-shaped rod 17 drives the push block 9 to slide relative to the straight plate 10, making the meshing teeth on the push block 9 re-engage with the planar thread groove 8.

[0039] Working principle: When the device is moved normally, the device is pushed to the position of the first hole punching by the handle on the driving component 25, then the driving component 25 is started and pressure is applied downward through the handle, so that the main body rod 26 drives the spiral blade 27 to cut the soil below. The soil is conveyed upward along the spiral blade 27, and at the same time, the soil throwing plate 28 strikes the upward moving soil fragments around, preventing the soil fragments from backfilling the planting hole, creating a good space for the growth of the roots of grape seedlings. After the first hole is punched, the device is pushed forward to drive the coupling shaft 14 and the threaded disc 7 to rotate synchronously by using the roller 4. When the threaded disc 7 rotates, the flat thread groove 8 on it interacts with the meshing teeth on the push block 9, and the push block 9 slides radially in the flat thread groove 8, pushing the straight plate 10 to move in the same direction. When the straight plate 10 moves, an oblique thrust is applied to the connecting plate 12 through the chute 11, so that the connecting plate 12 rotates around the connecting column 21, and then drives the brake block 13 to approach the roller 4. According to the preset number of rotation circles of the roller 4 (this number of circles is determined according to the planting spacing of grape seedlings and the circumference of the roller 4), when the threaded disc 7 rotates to the corresponding number of circles, the push block 9 drives the straight plate 10 to move to a specific position, and the brake block 13 is in close contact with the outer contour surface of the roller 4, and the roller 4 is stopped by using the friction force. At this time, the device reaches the predetermined hole opening position and the next hole punching operation can be carried out. Such precise positioning and hole opening can ensure that the grape seedlings have reasonable spacing, avoid the plants blocking each other and competing for nutrients due to unreasonable spacing, be beneficial to the growth and development of grape plants, and improve the yield and quality of grape fruits. If it is necessary to adjust the spacing between adjacent planting holes, the mounting plate 2 can be moved upward. The mounting plate 2 pushes the adjusting plate 23 to compress the return spring 24. The adjusting plate 23 drives the steering plate 15 to move upward through the guide plate 22. The guiding inclined groove 16 of the steering plate 15 makes the L-shaped rod 17 drive the push block 9 to move. The meshing teeth on the push block 9 are disengaged from the flat thread groove 8, and the straight plate 10 moves reversely under the action of the compression spring 18 until it contacts the limit disc 20. At this time, the position of the limit disc 20 can be adjusted by rotating the threaded rod 19, changing the moving range of the straight plate 10, and then adjusting the preset number of rotation circles of the threaded disc 7 and the roller 4. After the adjustment is completed, the mounting plate 2 is moved downward to make the meshing teeth on the push block 9 mesh with the flat thread groove 8 again, meeting the requirements for different planting hole spacings in the grape planting process, and improving the applicability of the device and the flexibility of grape planting.
