Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a wheat ridging and seeding machine with adjustable crop spacing. Background Technology

[0002] A wheat ridging and seeding machine is an agricultural machine whose main function is to complete multiple processes in one operation, including stubble removal, rotary tillage, fertilization, ridging, and sowing. This machine works by using a special seed metering device for small seeds to achieve precision sowing, and employs a convex double-disc furrow opener to better adapt to different working environments such as paddy fields and dry fields. Powered by an electric motor, it avoids seedling gaps caused by wheel slippage.

[0003] Different wheat varieties have different growth habits and characteristics, so it is necessary to control different ridging and sowing spacing. For example, common wheat is generally ridged and sown with a row spacing of 20-30 cm. Durum wheat, due to its strong resistance and adaptability, can be ridged and sown with a slightly wider row spacing. Soft wheat usually requires more water and nutrients to support its growth and development, so it needs to be ridged and sown with a narrower row spacing. However, existing ridging and sowing machines are inconvenient to adjust the sowing spacing during sowing, which leads to poor practicality of the ridging and sowing machine. Therefore, we propose a wheat ridging and sowing machine with adjustable crop spacing. Summary of the Invention

Therefore, they should not be construed as limitations on this invention.

[0031] Example 1:

[0032] Please see Figures 1 to 8 As shown, a wheat ridging and seeding machine with adjustable crop spacing includes:

[0033] A fixed frame 1 is provided, a connecting frame 2 is fixedly installed on one side of the fixed frame 1, and a soil turning shovel 3 is fixedly installed on both sides of the bottom of the connecting frame 2. The fixed frame 1 is rotatably equipped with moving wheels 4 on both sides, and an installation frame 5 is fixedly installed on the top of the fixed frame 1.

[0034] In this system, the connecting frame 2 is connected to the tractor, and the electrical components of the ridging seeder are controlled via a control panel on the tractor. The ridging and sowing spacing of the ridging seeder can be flexibly adjusted via the control panel.

[0035] The seed placement box 6 is installed inside the mounting frame 5, and a feeding component is installed at the bottom of the seed placement box 6. A sowing component is also fixedly installed inside the fixing frame 1, and the bottom of the feeding component is connected to the inside of the sowing component. The wheat seeds inside the seed placement box 6 are metered and fed into the inside of the sowing component through the feeding component, and the sowing component is used to automatically sow the wheat seeds.

[0036] The ridging assembly has ridging components fixedly installed on both sides inside the fixed frame 1, and a drive frame 7 is fixedly installed on the top of the fixed frame 1. A drive motor 8 is fixedly installed in the middle of the drive frame 7. Lifting frames 9 are slidably installed on both sides inside the drive frame 7, and drive rods 10 are threaded inside the lifting frames 9. A first rotating rod 11 is rotatably installed on one side inside the drive frame 7. The surface of the first rotating rod 11, the surfaces of the two drive rods 10, and the surface of the output shaft of the drive motor 8 are all movably equipped with first pulleys 12 via miniature electric cylinders. Four first pulleys... The surfaces of the wheels 12 are all connected by belt drive. The bottoms of the two lifting frames 9 are respectively connected to the tops of the two ridging components. The surfaces of the first rotating rod 11 and the two driving rods 10 are provided with slots that cooperate with the driving ends of the micro electric cylinders. At the same time, a micro electric cylinder is fixedly installed inside the first pulley 12. By controlling the driving end of the micro electric cylinder to cooperate with the slots on the surfaces of the first rotating rod 11 and the two driving rods 10, the first rotating rod 11 and the two driving rods 10 can drive the corresponding first pulley 12 to rotate synchronously when they rotate.

[0037] It should be noted that the output shaft of the drive motor 8, in conjunction with the first pulley 12 and the belt, controls the rotation of the two drive rods 10 inside the drive frame 7. During the clockwise rotation of the two drive rods 10, the two lifting frames 9 slide down synchronously inside the drive frame 7, thereby achieving the lifting and lowering control of the positions of the two ridging components.

[0038] The feeding assembly includes a guide frame 13. The guide frame 13 is fixedly installed at the bottom of the seed placement box 6, and a metering frame 14 is rotatably installed inside the guide frame 13. A connecting block 35 is fixedly installed on one side of the guide frame 13, and a second rotating rod 15 is rotatably installed inside the connecting block 35. One end of the second rotating rod 15 is fixedly connected to the inside of the metering frame 14. A first transmission rod 16 is also rotatably installed inside the drive frame 7. A second pulley 17 is fixedly installed on the surface of both the second rotating rod 15 and the first transmission rod 16. The surfaces of the two second pulleys 17 are connected by belt drive. A first helical gear 18 is fixedly installed at one end of both the first rotating rod 11 and the first transmission rod 16, and the tooth surfaces of the two first helical gears 18 mesh and drive each other.

[0039] A material discharge port is provided in the middle of the bottom of the inner wall of the seed placement box 6. Suction grooves 19 are provided on both sides of the inside of the guide frame 13, and suction pipes 20 are fixedly installed inside the two suction grooves 19. Suction pumps are provided at the other end of the two suction pipes 20.

[0040] It should be noted that when quantitatively feeding wheat seeds, the wheat seeds are placed inside the seed placement box 6. The first rotating rod 11 is connected to the first pulley 12 on its surface, while the connection between the two drive rods 10 and the two first pulleys 12 is simultaneously released. The output shaft of the drive motor 8 drives the first rotating rod 11 to rotate via the first pulley 12. The first rotating rod 11 drives the first transmission rod 16 to rotate via the first helical gear 18. The second rotating rod 15 is then controlled to rotate via the second pulley 17 on the surface of the first transmission rod 16 and the second rotating rod 15. The second rotating rod 15 then drives the quantitative frame 14 to rotate clockwise. The quantitative rack 14 has three quantitative chambers on its surface. These chambers are used to quantitatively process the wheat seeds inside the seed storage box 6. After the quantitative rack 14 is rotated 90 degrees clockwise, the wheat seeds inside the quantitative chambers fall into the suction trough 19. The wheat seeds inside the suction trough 19 are then extracted by the suction pipe 20. The output shaft of the drive motor 8 is then rotated 180 degrees counterclockwise, causing the quantitative rack 14 to rotate 180 degrees counterclockwise. This allows the quantitative chamber on one side to send the wheat seeds into the suction trough 19 on the other side, enabling the two suction pipes 20 to efficiently extract and feed the wheat seeds inside the suction trough 19.

[0041] Example 2:

[0042] This embodiment specifically discloses the detailed structure of the sowing component in Embodiment 1 above. The sowing component includes a fixed frame 21 and a sowing rack 22. The fixed frame 21 is fixedly installed inside the fixed frame 1, and a third rotating rod 23 is rotatably installed inside the fixed frame 21. Mounting frames 24 are movably installed on both sides inside the fixed frame 21, and the tops of the two mounting frames 24 are threadedly connected to the two sides of the surface of the third rotating rod 23, respectively. The two sides of the surface of the third rotating rod 23 are provided with external threads with opposite directions of rotation. When the third rotating rod 23 rotates clockwise, the two mounting frames 24 move relative to each other, and vice versa. A second transmission rod 25 is fixedly installed at one end of the output shaft of the drive motor 8 through a coupling, and a second helical gear 26 is fixedly installed at one end of the second transmission rod 25 and the middle part of the surface of the third rotating rod 23. The tooth surfaces of the two second helical gears 26 mesh with each other for transmission.

[0043] Furthermore, a first servo electric cylinder 27 is fixedly installed on the top of each of the two fixed frames 21, and a seeding rack 22 is slidably installed inside each of the two fixed frames 21. The driving ends of the two first servo electric cylinders 27 are fixedly connected to the top of the two seeding racks 22 respectively, and the bottom of each of the two seeding racks 22 is provided with an opening and closing plate by rotating a micro motor. One end of the suction pipe 20 is connected to the inside of the seeding rack 22.

[0044] It should be noted that a miniature electric cylinder is fixedly installed inside the second transmission rod 25, and a limit sleeve is provided at the drive end of the miniature electric cylinder. One end of the limit sleeve is movably connected to the output shaft of the drive motor 8. The limit sleeve is controlled by the miniature electric cylinder to connect the second transmission rod 25 to the output shaft of the drive motor 8, and then the drive motor 8 controls the second transmission rod 25 to rotate. Under the cooperation of the two second helical gears 26, the third rotating rod 23 rotates inside the fixed frame 21. The rotation of the third rotating rod 23 adjusts the position of the two mounting frames 24 inside the fixed frame 21, allowing the two... The seeding frame 22 can be synchronously adjusted with the adjustment of the ridge spacing. During the seeding process, the seeding frame 22 is inserted into the ridge by the drive end of the first servo cylinder 27. After the opening and closing plate at the bottom of the seeding frame 22 is opened, the wheat seeds inside the seeding frame 22 fall into the ridge. Then, the seeding frame 22 is reset to complete the automatic seeding process. The seeding depth of the wheat seeds inside the ridge can be flexibly controlled by the extension length of the drive end of the first servo cylinder 27, and different seeding depths can be flexibly controlled according to different soil conditions and wheat seed types.

[0045] Example 3:

[0046] This embodiment specifically discloses the detailed structure of the ridging component in Embodiment 1 above. The ridging component includes a connecting frame 28, a movable frame 29, and a ridging frame 30. Connecting frames 28 are fixedly mounted on both sides of the bottom of the fixed frame 1 by bolts, and movable frames 29 are movably mounted inside each of the two connecting frames 28. The bottoms of the two lifting frames 9 pass through the two connecting frames 28 and extend into their interiors. The bottoms of the two lifting frames 9 are fixedly connected to the tops of the two movable frames 29. A fourth rotating rod 31 is rotatably mounted inside the movable frame 29. Both ends of the fourth rotating rod 31 pass through the movable frame 29 and extend to the outside of the movable frame 29. Both ends of the fourth rotating rod 31 are fixedly provided with drive gears 32. Both sides of the inner wall of the connecting frame 28 are fixedly provided with second servo electric cylinders 33, and both drive ends of the second servo electric cylinders 33 are fixedly provided with tooth plates 34. Two ridging frames 30 are slidably provided at the bottom of the connecting frame 28, and the tops of the two ridging frames 30 are respectively threaded to both sides of the surface of the fourth rotating rod 31. The two sides of the surface of the fourth rotating rod 31 are provided with external threads with opposite directions of rotation.

[0047] It should be noted that when adjusting the spacing between the two ridging frames 30 at the bottom of the connecting frame 28, the second servo electric cylinders 33 on both sides of the inner wall of the connecting frame 28 control the meshing transmission between the toothed plate 34 and the drive gear 32. Then, the two lifting frames 9 control the movable frame 29 to move downward inside the connecting frame 28. As the movable frame 29 moves downward, the drive gear 32 meshes on one side of the toothed plate 34, causing the drive gear 32 to drive the fourth rotating rod 31 to rotate. During the rotation of the fourth rotating rod 31, the two ridging frames 30 are connected... The spacing of the bottom of frame 28 is adjusted. After the spacing of the ridging frame 30 is adjusted, the rotation of the drive gear 32 is locked by the toothed plate 34. The spacing of the ridging frame 30 is flexibly adjusted for different types of wheat seeds and different soil conditions. When using the ridging seeder, the soil is first ridged by the ridging frame 30 on the side close to the turning shovel 3. Then, the wheat seeds are automatically sown inside the ridge by the sowing frame 22. Finally, the surface of the ridge after sowing is repaired by the ridging frame 30 on the other side to ensure the ridging and sowing effect of wheat seeds.

[0048] Example 4:

[0049] This embodiment specifically discloses a working method for a wheat ridging and seeding machine with adjustable crop spacing, the specific working method of which is as follows:

[0050] Step 1: First, adjust the spacing of the ridging frame 30 according to different types of wheat seeds and different soil conditions. The second servo electric cylinder 33 on both sides of the inner wall of the connecting frame 28 controls the meshing transmission between the toothed plate 34 and the surface of the drive gear 32. Then, the two lifting frames 9 control the movable frame 29 to move downward inside the connecting frame 28. As the movable frame 29 moves downward, the drive gear 32 meshes on one side of the toothed plate 34, causing the drive gear 32 to drive the fourth rotating rod 31 to rotate. During the rotation of the fourth rotating rod 31, the spacing of the two ridging frames 30 at the bottom of the connecting frame 28 is adjusted.

[0051] Step 2: The soil is ridged using the ridging frame 30 after the spacing adjustment. Then, the first rotating rod 11 is connected to the first pulley 12 on its surface, while the connection between the two drive rods 10 and the two first pulleys 12 is released. The output shaft of the drive motor 8 drives the first rotating rod 11 to rotate via the first pulley 12. The first rotating rod 11 drives the first transmission rod 16 to rotate via the first helical gear 18. The second rotating rod 15 is then controlled to rotate via the second pulley 17 on the surface of the first transmission rod 16 and the second rotating rod 15. 15 drives the metering frame 14 to rotate 90 degrees clockwise. The surface of the metering frame 14 is provided with three metering chambers. The three metering chambers are used to meter the wheat seeds inside the seed placement box 6. After controlling the metering frame 14 to rotate 90 degrees clockwise, the wheat seeds inside the metering chambers fall into the suction trough 19. Then, the wheat seeds inside the suction trough 19 are extracted through the suction pipe 20. Then, the output shaft of the drive motor 8 is controlled to rotate 180 degrees counterclockwise, so that the metering frame 14 rotates 180 degrees counterclockwise, thereby sending the wheat seeds from one metering chamber to the suction trough 19 on the other side.

[0052] Step 3: The second transmission rod 25 is connected to the output shaft of the drive motor 8 by the limit sleeve controlled by the micro electric cylinder. Then, the second transmission rod 25 is rotated by the drive motor 8. Under the action of the two second helical gears 26, the third rotating rod 23 is rotated inside the fixed frame 21. The rotation of the third rotating rod 23 adjusts the position of the two mounting frames 24 inside the fixed frame 21, so that the two sowing frames 22 can be adjusted synchronously with the adjustment of the ridging spacing. During the sowing process, the sowing frame 22 is inserted into the ridge by the drive end of the first servo electric cylinder 27. After the opening and closing plate at the bottom of the sowing frame 22 is opened, the wheat seeds inside the sowing frame 22 fall into the ridge. Then, the sowing frame 22 is reset to complete the automatic sowing of wheat seeds.

[0053] Step 4: After the wheat seeds are automatically sown using the sowing frame 22, the ridges are repaired using the rear ridging frame 30.
