Description

Technical Field

[0001] The invention relates to the technical field of cotton planting, in particular to a cotton planting punching device. Background Art

[0002] Cotton is an important economic crop for the nation. Cotton fiber is mainly used in textiles and is the main raw material for clothes and quilts. It is a renewable natural fiber and has incomparable permeability, warmth retention, durability, wear resistance, washability, and high-temperature ironing properties that chemical fibers cannot match. It is deeply loved by people. Cotton is an important commodity involving the two major industries of agriculture and textile industry. It is the main raw material of the textile industry, an important commodity for export and foreign exchange earnings, and an indispensable necessity for the general public.

[0003] Cotton cultivation usually uses machinery to sow cotton seeds on large farms, and simultaneously complete tasks such as mulching, sowing, laying water pipes and applying fertilizers. It is highly efficient and suitable for large-scale cultivation. However, cotton seedlings are prone to death, and the cotton seedlings need to be replanted after large-scale planting.

[0004] In order to improve the survival rate of cotton, transplanting is usually adopted. Cotton seeds are first planted in paper pots. After the cotton seedlings grow out, the cotton seedlings are transplanted into the cotton fields. This method has a high survival rate and does not require large-scale seedling replacement in the later stage.

[0005] Transplanting usually requires drilling holes in the field first, then planting the cotton seedlings and paper pots in the holes, and finally covering the soil. The existing drilling device usually arranges a drilling head on a rotary wheel. Since the drilling head rotates with the rotary wheel, the holes it drills are usually elliptical, which makes it impossible to keep the cotton seedlings upright and is not convenient for subsequent soil covering operations, resulting in low work efficiency and more physical exertion.

[0006] Therefore, a cotton planting punching device is needed to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings. Figures 1-15 As shown, a cotton planting punching device includes two groups of cross beams 1 arranged in front and back, and the two groups of cross beams 1 are connected by two longitudinal beams 11. The two longitudinal beams 11 are coaxially connected to the rotating wheel 13 on the side away from each other. A traction frame 12 is fixedly provided on the front cross beam 1. By setting the traction frame 12, it can be connected to a tractor, and the entire punching device can be driven forward and raised and lowered by the tractor.

[0023] See also Figure 2 and Figure 3 , multiple flip assemblies 2 are evenly distributed in parallel on the crossbeam 1, and adjacent flip assemblies 2 are connected by a transmission shaft 14. The runner 13 is fixed on the rotating shaft 132, and the rotating shaft 132 is rotatably connected to the longitudinal beam 11 through the bearing seat 131. The driving double sprocket 15 is fixedly sleeved on the rotating shaft 132, and the driving double sprocket 15 and the driven double sprocket 17 are connected by a double chain 16. The driven double sprocket 17 is rotatably set on the flip assembly 2. When working, the runner 13 rotates on the ground, and the runner 13 drives the driving double sprocket 15 to rotate through the rotating shaft 132. The driving double sprocket 15 drives the driven double sprocket 17 to rotate through the double chain 16. The driven double sprocket 17 transmits power to the flip assembly 2, and the flip assembly 2 drives the adjacent flip assemblies 2 to work through the transmission shaft 14, so that multiple flip assemblies 2 can work simultaneously.

[0024] See also Figure 4 The turning assembly 2 includes two parallel horizontal bars 22. The upper and lower ends of the two horizontal bars 22 are fixedly connected to mutually parallel longitudinal bars 21. The longitudinal bars 21 and the horizontal bars 22 are arranged perpendicularly. The middle part of the longitudinal bar 21 on the upper side of one end of the horizontal bar 22 is rotatably connected to the first turntable 23, and the middle part of the longitudinal bar 21 on the lower side of the other end of the horizontal bar 22 is rotatably connected to the second turntable 25. The first turntable 23 and the second turntable 25 are both cross-shaped and have the same shape and structure. A plurality of punching assemblies 3 are arranged between the first turntable 23 and the second turntable 25. The first turntable 23 and the second turntable 25 rotate, and the first turntable 23 and the second turntable 25 drive the punching assembly 3 to move up and down. When the punching assembly 3 moves downward, it performs a drilling operation on the ground. When drilling, the cotton seedlings in the paper pot are placed into the holes. When the punching assembly 3 moves upward, the cotton seedlings are covered with soil, completing the transplanting of the cotton seedlings.

[0025] See also Figure 3-Figure 6 Each cross end of the first turntable 23 and the second turntable 25 is rotatably connected to the support rod 24, and the adjacent support rods 24 on the first turntable 23 and the second turntable 25 are fixedly connected to the same punching assembly 3. Since the first turntable 23 and the second turntable 25 are respectively rotatably connected to the longitudinal rod 21 on the upper and lower sides of the cross bar 22, the first turntable 23 and the second turntable 25 are in an eccentric setting. When the first turntable 23 and the second turntable 25 rotate, due to the restriction of the support rod 24, the punching assembly 3 is always in a vertical state.

[0026] The circumference of the support rods 24 on the first turntable 23 and the second turntable 25 is the same as the radius of the outer circumference of the rotating wheel 13, the number of teeth of the active double sprocket 15 and the driven double sprocket 17 is the same, and the driven double sprocket 17 and the first turntable 23 are coaxially fixedly connected. When the rotating wheel 13 rotates, the rotating speed of the rotating wheel 13 and the first turntable 23 is the same. At the same time, since the circumference of the support rods 24 on the first turntable 23 and the second turntable 25 is the same as the radius of the outer circumference of the rotating wheel 13, the linear speed of the support rods 24 on the first turntable 23 and the second turntable 25 and the rotating wheel 13 is the same. Therefore, when the rotating wheel 13 rotates, the first turntable 23 and the second turntable 25 can drive the punching assembly 3 to move only in the vertical direction relative to the ground, without moving in the horizontal direction, and can keep the punching assembly 3 and the ground always in a vertical state, ensuring that the punching is also in a vertical state.

[0027] See also Figure 6 Four ribs 241 are evenly distributed around the periphery of the support rod 24. The ribs 241 are parallel to the axis of the support rod 24. The arrangement of the ribs 241 improves the bending resistance of the support rod 24, improves the strength of the support rod 24, and can more stably control the movement of the punching assembly 3.

[0028] See also Figure 7-Figure 9The punching assembly 3 includes a hollow cylinder 31, and a hopper 312 is provided inside the upper end of the cylinder 31. The hopper 312 is convenient for placing the cotton seedling paper pot into the cylinder 31. A seat and a material tray can be provided on the beam 1. The cotton seedling paper pot can be placed into the hopper 312 manually. A discharging mechanism can also be provided to cooperate with the movement of the hopper 312 to place the cotton seedling paper pot into the hopper 312. The movement of the hopper 312 can also drive the cotton seedling paper pot to separate from the material tray and enter the hopper 312. The discharge structure of the cotton seedling paper pot belongs to the existing technology and will not be described here. The outside of the cylinder 31 is sleeved with a fixed ear plate 311, and the upper and lower ends of the fixed ear plate 311 are fixedly connected to a support rod 24, and the fixed ear plate 311 and the cylinder 31 are driven to move by the support rod 24. The outside of the cylinder 31 is fixedly sleeved with a drive ring 32, and the drive ring 32 is radially threaded and connected to a locking bolt. The locking bolt fixes the drive ring 32 to the cylinder 31, and the drive ring 32 is arranged on the outside of the cylinder 31 on the lower side of the fixed ear plate 311.

[0029] The lower end of the drive ring 32 abuts against a spring 321, which in turn abuts against the outer side of the inner ring of a bearing 341. The upper side of the outer ring of the bearing 341 abuts against a retaining ring 342, which is bolted to the end of the rotating drum 34. The upper and lower ends of the rotating drum 34 are both bolted to retaining rings 342. The sides of the two retaining rings 342 that are closest to each other abut against the bearing 341, which is then sleeved over the upper and lower ends of the sliding sleeve 36. The arrangement of the bearing 341 and retaining ring 342 ensures that the rotating drum 34 and the sliding sleeve 36 are relatively fixed in the axial direction, while being able to rotate relative to each other in the circumferential direction.

[0030] See also Figure 10-12 A plurality of one-way latch teeth 343 are evenly distributed circumferentially on the inner side of the rotating drum 34. The one-way latch teeth 343 are parallel to the axis of the rotating drum 34. A retractable one-way latch plate 362 is radially arranged on the outer side of the sliding sleeve 36. An extrusion spring is arranged between the one-way latch plate 362 and the inner wall of the sliding sleeve 36 to keep the one-way latch plate 362 in an extended state through the extrusion spring.

[0031] The one-way clamping plate 362 is clamped on the one-way clamping tooth 343 . The one-way clamping plate 362 and the one-way clamping tooth 343 restrict the microphone sleeve 36 from rotating in only one direction relative to the rotating drum 34 .

[0032] A sliding key 361 is provided on the outside of the cylinder 31, and the sliding sleeve 36 is slidably connected to the outside of the sliding key 361. Through the setting of the sliding key 361, the sliding sleeve 36 and the cylinder 31 can only move axially, and the sliding sleeve 36 and the cylinder 31 are relatively fixed in the circumferential direction. In this way, the rotating drum 34 can also rotate unidirectionally relative to the cylinder 31.

[0033] See also Figure 9-10 and Figure 13The upper side of the retaining ring 342 at the upper end of the rotating cylinder 34 is bolted to the driving cylinder 33, and a plurality of groups of slides are evenly distributed on the inner side of the driving cylinder 33. Each group of slides includes an axially arranged first slide 331, the lower end of the first slide 331 is connected to the second slide 332, the second slide 332 is adjacent to and parallel to the first slide 331, and the upper end of the second slide 332 is connected to the third slide 333. The angle between the third slide 333 and the second slide 332 is an obtuse angle. The first slide 331 and the third slide 333 of the two adjacent groups of slides are connected, and the first slide 331, the second slide 332, and the third slide 333 are all in a straight line.

[0034] A driving post 322 is provided on the outside of the driving ring 32 , and the driving post 322 is slidably connected in the first slideway 331 , the second slideway 332 , and the third slideway 333 .

[0035] See also Figure 9 The lower side of the retaining ring 342 at the lower end of the rotating drum 34 is bolted to the covering disc 35. A plurality of radially arranged arc-shaped covering pieces 351 are evenly distributed around the lower side of the covering disc 35. During operation, the covering disc 35 drives the covering pieces 351 to rotate. When the covering pieces 351 rotate, the soil moves toward the center, completing the soil covering work for the cotton seedlings.

[0036] During operation, the flip component 2 drives the punching component 3 to move vertically back and forth relative to the ground. When the punching component 3 moves downward, the lower end of the cylinder 31 first contacts the ground and moves downward. The cylinder 31 punches holes in the ground. After the punching is completed, the cotton seedling paper pot enters the hole through the cylinder 31 to complete the planting.

[0037] As the cylinder 31 moves downward, the covering plate 35 comes into contact with the ground until the covering piece 351 is inserted into the soil, and the covering plate 35 stops moving. At this time, the cylinder 31 continues to move downward, and the covering plate 35 pushes the driving cylinder 33, the rotating cylinder 34 and the sliding sleeve 36 to move upward relative to the cylinder 31. At this time, the driving column 322 on the outside of the driving ring 32 moves downward along the first slide 331 until the driving column 322 enters the bottom end of the second slide 332. At this time, the cylinder 31 moves downward into place and no longer moves downward.

[0038] After the lifting of the lifting mechanism 321, the driving column 322 on the outside of the driving ring 32 moves upward along the second slide 332 until the driving column 322 moves to the upper end of the second slide 332. At this time, the cylinder 31 is separated from the ground and the cotton seedling paper pot, and the cylinder 31 continues to move upward. At this time, the driving column 322 on the outside of the driving ring 32 enters the third slide 333. Since the third slide 333 is in an inclined state, the driving column 322 will drive the driving cylinder 33 to rotate. The driving cylinder 33 drives the rotating cylinder 34 and the covering plate 35 to rotate. The covering plate 35 drives the covering piece 351 to rotate, and the soil is moved to the center to complete the covering of the cotton seedling paper pot. After the soil covering is completed, the driving column 322 enters the top of the first slide 331 of the next group of slides to prepare for the next work.

[0039] See also Figure 14 and Figure 15 Two symmetrically arranged hinges 38 are welded to the lower end of the cylinder 31, and a half cone 37 is welded at each end of the hinge 38. When the two half cones 37 are closed, the lower end of the cylinder 31 is closed to prevent soil from entering the cylinder 31, so that the cotton seedling paper pot can slide smoothly to the lower end of the cylinder 31. The outer side of the hinge 38 is hinged to the movable bar 39, and a slide groove 391 is provided at the upper end of the movable bar 39. The push rod 3641 is slidably connected in the slide groove 391. The push rod 3641 is fixedly connected to the lower end of the push bar 364. The upper end of the push bar 364 is bolted to the lower side of the connecting ring plate 363, and the connecting ring plate 363 is bolted to the sliding sleeve 36.

[0040] By sliding the sliding sleeve 36 up and down on the cylinder 31, the sliding sleeve 36 drives the push bar 364 to move up and down. When the push bar 364 moves upward, the push bar 364 drives the push rod 3641 to slide upward in the slide groove 391 until the push rod 3641 slides to the top of the slide groove 391. At this time, the push rod 3641 continues to move upward, and the push rod 3641 drives the moving bar 39 to move upward. The moving bar 39 drives the semi-cone 37 to flip outward, thereby releasing the seal on the lower end of the cylinder 31, making it easier for the cotton seedling paper pot to detach from the cylinder 31.

[0041] When the push bar 364 moves downward, the push rod 3641 will squeeze the lower end of the slide groove 391, pushing the moving bar 39 to move downward. The moving bar 39 drives the two semi-cones 37 to close, sealing the lower end of the cylinder 31 to prevent soil from entering the cylinder when the cylinder 31 moves downward. It can also keep the cotton seedling paper pot in the cylinder 31 to prevent the cotton seedling paper pot from detaching from the lower end of the cylinder 31.

[0042] Four sets of turning assemblies 2 are provided on the crossbeam 1, and four sets of punching assemblies 3 are provided on each set of turning assemblies 2. By providing multiple sets of turning assemblies 2 on the crossbeam 1, cotton seedlings can be planted in multiple rows at the same time, thereby improving planting efficiency. By adjusting the number of punching assemblies 3 on each set of turning assemblies 2, the planting distance of the cotton seedlings can be adjusted.

[0043] Working process: The punching device is connected to the tractor through the traction frame 12. After planting begins, the punching device is lowered, the wheel 13 contacts the ground, and then the tractor drives the punching device forward through the traction frame 12.

[0044] During the forward movement, the rotating wheel 13 transmits power to the turning assembly 2 through the double chain 16 , and the turning assembly 2 transmits power to each turning assembly 2 through the transmission shaft 14 .

[0045] The turning assembly 2 rotates, driving the punching assembly 3 to reciprocate vertically relative to the ground. As the punching assembly 3 moves downward, the spring 321 pushes the drive cylinder 33, the rotating cylinder 34, and the covering plate 35 to the lowest end of the cylinder 31. The push rod 3641 of the push bar 364 is at the lowest end of the slide 391, pushing the moving bar 39 to merge the two semi-cones 37. The semi-cones 37 seal the lower end of the cylinder 31 and have a pointed lower end, which facilitates drilling holes in the ground.

[0046] As the cylinder 31 moves downward, the soil covering plate 35 comes into contact with the ground until the soil covering piece 351 is inserted into the soil, at which point the soil covering plate 35 stops moving. At this point, the cylinder 31 continues to move downward, and the soil covering plate 35 pushes the drive cylinder 33, the rotating cylinder 34, and the sliding sleeve 36 to move upward relative to the cylinder 31. At this time, the drive post 322 outside the drive ring 32 moves downward along the first slide 331 until the drive post 322 enters the bottom end of the second slide 332. At this time, the cylinder 31 moves downward into place and no longer moves downward. During this process, the push bar 364 drives the push rod 3641 to slide upward in the slide groove 391 until the push rod 3641 slides to the top of the slide groove 391. At this time, the push rod 3641 continues to move upward, driving the moving bar 39 upward. The moving bar 39 drives the semi-cone 37 to flip outward, releasing the seal on the lower end of the cylinder 31, allowing the cotton seedling paper pot to separate from the cylinder 31 and enter the hole.

[0047] The cylinder 31 then moves upward, and under the push of the spring 321, the drive cylinder 33, the rotating cylinder 34, and the sliding sleeve 36 move downward relative to the cylinder 31. At this time, the drive post 322 outside the drive ring 32 moves upward along the second slide 332 until the drive post 322 moves to the upper end of the second slide 332. At this time, the cylinder 31 is separated from the ground and the cotton seedling pot. During this process, the push rod 3641 slides in the slide groove 391. At this time, the push rod 3641 does not push the moving bar 39 to move. The two semi-cones 37 are in an open state, which facilitates the separation of the cylinder 31 and the cotton seedling pot and prevents the semi-cones 37 from supporting the cotton seedling pot, causing the cotton seedling pot to separate from the hole and fail to be planted normally.

[0048] The cylinder 31 continues to move upward, and the driving column 322 on the outside of the driving ring 32 enters the third slide 333. Since the third slide 333 is in an inclined state, the driving column 322 will drive the driving cylinder 33 to rotate, and the driving cylinder 33 drives the rotating cylinder 34 and the covering plate 35 to rotate. The covering plate 35 drives the covering piece 351 to rotate, and the soil is moved closer to the center to complete the covering of the cotton seedling paper pot. After the covering is completed, the driving column 322 enters the top of the first slide 331 of the next group of slides to prepare for the next work.
