A chain-spoon type potato planter seed cleaning device

Abstract

This invention relates to the field of agricultural machinery and equipment technology, specifically a seed cleaning device for a chain-spoon type potato planter, including a seed box with a vibration mechanism fixedly installed on the side wall of the seed box. In this invention, the seed spoon is able to rise, causing the rollers on both sides to abut against an arc-shaped rod that gradually moves towards the seed dispensing chain. As the rollers roll on the surface of the arc-shaped rod, they drive a moving column to slide within a square tube, thereby causing two arc-shaped clamps in the seed holding trough to move closer together and clamp a single seed potato. A compression spring is installed between the moving column and the connecting column to prevent excessive compression force from damaging the seed potato and affecting its subsequent growth. Afterward, the seed spoon moves to a horizontal position at the top of the seed dispensing chain, maintaining a vertical conveying state. Excess seed potatoes in the seed spoon will roll off under gravity, thus cleaning up excess seed potatoes while retaining only one seed potato in the seed holding trough.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically a seed cleaning device for a chain-spoon type potato planter. Background Technology

[0002] The planting method of the chain-type potato planter mainly relies on its core component—the chain-type seed metering device. This device primarily consists of a drive sprocket, a driven sprocket, multiple seed-collecting scoops, a chain, and a seed-protecting cover. During operation, the ground wheel rotates, driving the drive sprocket to rotate, which in turn moves the seed-collecting scoops upwards via the chain. During this upward movement, the seed-collecting scoops take one or more seed potatoes from the seed box.

[0003] Currently, there are many seed cleaning devices for potato planters. Among them, typical examples are the potato planter vibration seed dispensing devices disclosed in Chinese patent documents with patent numbers CN201220705417.4, CN201621409699.8, and CN201620381583.1. Although these devices can improve seed cleaning efficiency, they are more suitable for situations where seed potatoes are stacked vertically within the seed scoop. When seed potatoes are arranged side by side within the seed scoop, they cannot effectively vibrate excess seed potatoes out of the scoop. Many scholars have also improved the structure of the seed scoop to reduce the replanting rate. Chinese patent documents such as CN201721500460.6, CN201821495137.9, CN202011259264.0, and CN202122428556.9 have been published. These seed scoops can reduce the possibility of scooping up too many potatoes during the seed scooping process, but the problem of a high replanting rate still exists. Replanting potatoes will lead to the gradual depletion of certain nutrients in the soil, especially the main nutrients required by potatoes, such as nitrogen, phosphorus, and potassium. This may lead to a decline in soil fertility and increase the occurrence of soil-borne diseases. Summary of the Invention

[0004] The purpose of this invention is to provide a seed cleaning device for a chain-spoon type potato planter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Furthermore, the front end of the seed spoon is provided with multiple bionic claws at equal intervals, the bionic claws having a height of 4-5mm, a thickness of 2-5mm, and a width of 3-6mm.

[0009] Furthermore, a receiving spoon is fixedly connected to the bottom of the seed spoon.

The end of the compression springs is fixedly connected with a connecting block that is slidably connected to the groove. The sprocket is rotatably connected to the connecting block.

[0013] Furthermore, the sweeping mechanism includes two L-shaped abutments fixedly connected to the seed box. The roller slides against the L-shaped abutments. An arc-shaped rod is fixedly connected to the ends of each of the two L-shaped abutments. Side baffles are fixedly connected to opposite sides of each of the two L-shaped abutments. A semi-circular cover is fixedly connected between the two L-shaped abutments. A support frame is fixedly connected to each L-shaped abutment. A rotating shaft is rotatably connected to the support frame. A bevel gear is fixedly connected to one end of the rotating shaft. A bevel gear is meshed with one side of the bevel gear. A synchronous gear is fixedly connected to the center of the bevel gear. A sleeve is fitted onto the synchronous gear. One end of the synchronous belt is fitted with a synchronous pulley that is fixedly fitted to the drive shaft. The other end of the shaft is fixedly connected to a disc. One end of a connecting rod is rotatably connected to the side wall of the disc. The other end of the connecting rod is rotatably connected to a sliding column. A limit ring is slidably fitted to the outside of the sliding column. Limit blocks are fixedly connected to both sides of the sliding column. A chamfered frame is fixedly connected between the top ends of the two L-shaped abutments. A swing plate is rotatably connected to the chamfered frame. A limit groove is provided in the swing plate that is slidably embedded in the limit block. Multiple elastic brushes are fixedly arranged at equal intervals at the bottom of the swing plate.

[0014] Furthermore, both sides of the elastic brush are provided with a recycling plate that is fixedly connected to the L-shaped abutment, and a baffle is fixedly connected to the recycling plate.

[0015] Furthermore, the vibration mechanism includes a motor support fixedly connected to the side wall of the seed box, a vibration motor fixedly sleeved in the motor support, an eccentric wheel fixedly connected to the output end of the vibration motor, and an adjusting plate fixedly connected to the bottom end of the motor support by a connecting pin. The adjusting plate has a U-shaped groove, and an adjusting bolt is provided in the U-shaped groove.

[0016] Furthermore, the seed cleaning mechanism includes a mounting column, a motor support second is fixedly connected to the side wall of the mounting column, a seed cleaning motor is fixedly installed in the motor support second, a base is fixedly connected to the output end of the seed cleaning motor, and four elastic seed brushes are arranged around the base. The elastic seed brushes are 80-100mm long, 25-30mm wide, and made of nylon.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The seed conveying mechanism drives multiple seed scoops to move upwards from the seed box. During this process, the seed scoops scoop multiple seed potatoes from the seed box. Then, the vibration mechanism outside the seed box drives the seed conveying chain and seed scoops to vibrate together. This shakes off the upper layer of seed potatoes piled in the seed scoops and they fall back into the seed box. The vibration causes a seed potato in the seed scoop to fall into the seed holding trough. Because the seed holding trough is deep, the seed potatoes in the seed holding trough are difficult to fall out due to vibration, thus ensuring that there is at least one seed potato in the seed scoop. As the seed conveying chain continues to drive, it can drive the seed scoop upwards, causing the rollers on both sides to come into contact with the arc-shaped rod that gradually moves towards the seed conveying chain. As the rollers roll on the surface of the arc-shaped rod, they drive the moving column to slide in the square tube. This causes the two arc-shaped clamps in the seed trough to move closer together and clamp a single seed potato. By installing a compression spring between the moving column and the connecting column, excessive compression force can be avoided, which could damage the seed potato and affect its subsequent growth. Afterward, the seed scoop moves to the top horizontal position of the seed dispensing chain. At this time, the seed scoop remains in a vertical conveying state. In this way, excess seed potatoes in the seed scoop will roll off to the outside under the action of gravity. This allows for the removal of excess seed potatoes while retaining only one seed potato in the seed trough, thereby reducing the replanting rate of the planter and improving the seed cleaning effect of the seed cleaning device.

[0019] 2. By moving the sliding seat in the C-shaped plate and then locking the sliding seat with the locking pin, the sliding seat can drive the adjusting plate to move, which in turn can drive the compression spring and the connecting block at both ends of the adjusting plate to move. The position of the sprocket can be adjusted through the connecting block, thus adjusting the tension of the seed metering chain. When the seed metering chain is tighter, the vibration effect generated by the vibration mechanism has a greater impact on the seed spoon, and vice versa. Thus, the tension of the seed metering chain can be adjusted as needed.

[0020] 3. The ground wheel drives the drive shaft and synchronous pulley one to rotate, which in turn drives synchronous pulley two to rotate under the action of the synchronous belt. Synchronous pulley two drives bevel gear one and bevel gear two to mesh and rotate. Then, the rotating shaft one drives the disc to rotate, which in turn drives the connecting rod to swing. One end of the connecting rod drives the sliding column to slide back and forth in the limit ring, so that the limit block at the end of the sliding column can slide back and forth in the limit groove. This drives the swing plate to drive the elastic brush at its bottom to swing back and forth. Multiple elastic brushes can sweep and clean the seed potatoes that roll off when the seed spoon is in a vertical position, preventing the seed potatoes from accumulating on the chain and causing conveying jams. The elastic brushes can also sweep the seed potatoes on the chain onto the recovery plates on both sides. The recovery plates are inclined arc-shaped plates. The seed potatoes roll back into the seed box along the curved surface of the recycling plate, thus recycling excess seed potatoes while cleaning them, which helps save agricultural resources. Baffles on the recycling plate prevent recycled seed potatoes from falling into the seed scoop. A cylindrical protective structure, formed by a semi-circular cover and side baffles between the two L-shaped abutments, prevents the seed potatoes from falling into the receiving scoop in the lower seed clamping mechanism when the seed scoop is flipped to face the ground due to chain vibration. The cylindrical protective structure prevents the seed potatoes from falling outside. When the rollers on the seed clamping mechanism separate from the L-shaped abutments, the seed scoop rotates, and individual seed potatoes are planted into the furrows, enabling the planter to perform precision planting.

[0021] 4. The output of the seed cleaning motor drives the base to rotate, which in turn drives the four elastic seed brushes on the side wall of the base to rotate. The elastic seed brushes can brush and clean the excess seed potatoes in the seed scoop, which helps to improve the seed cleaning efficiency of the device. The output of the vibration motor in the vibration mechanism drives the eccentric wheel to rotate, which in turn drives the seed discharging chain and multiple seed scoops to vibrate. This can shake the seed potatoes accumulated on the seed scoops off, reducing the subsequent seed cleaning pressure. Attached Figure Description

[0034] 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.

[0035] Please see Figures 1-11 In this embodiment of the invention, a seed cleaning device for a chain spoon type potato planter includes a seed box 1, a vibration mechanism 100 fixedly installed on the side wall of the seed box 1, a seed cleaning mechanism 200 fixedly installed inside the seed box 1, a seed dispensing and conveying mechanism 300 installed outside the seed box 1, a plurality of seed clamping mechanisms 400 fixedly installed at equal intervals on the seed dispensing and conveying mechanism 300, and a sweeping mechanism 500 installed on the top of the seed dispensing and conveying mechanism 300.

[0036] The seed clamping mechanism 400 includes a seed spoon 401, with two fixing members 402 symmetrically fixedly connected to the end of the seed spoon 401. A seed holding groove 403 is provided at the center of the seed spoon 401. Two square tubes 406 are symmetrically fixedly connected to the outer wall of the seed spoon 401. A moving column 407 is slidably sleeved in the square tube 406. A roller 408 is rotatably connected to one end of the moving column 407. A slide rod 410 is fixedly connected to the other end of the moving column 407. A sleeve post 412 is slidably sleeved on the outside of the slide rod 410. A compression spring 411 is fixedly connected between the sleeve post 412 and the moving column 407. An arc-shaped clamping plate 413 is fixedly connected to the end of the sleeve post 412. A return spring 409 is fixedly connected to the side wall of the moving column 407. A receiving spoon 404 is fixedly connected to the bottom of the seed spoon 401.

[0037] Specifically, the seed conveying mechanism 300 drives multiple seed scoops 401 to move upwards from the seed box 1. During this process, the seed scoops 401 scoop multiple seed potatoes from the seed box 1. Then, the vibration mechanism 100 outside the seed box 1 causes the seed conveying chain 302 and the seed scoops 401 to vibrate together. This shakes off the upper layer of seed potatoes piled in the seed scoops 401 and they fall back into the seed box 1. The vibration causes a seed potato in the seed scoop 401 to fall into the seed holding trough 403. Because the seed holding trough 403 is deep, the seed potatoes in the seed holding trough 403 are difficult to be shaken off, thus ensuring that there is at least one seed potato in the seed scoop 401. As the seed conveying chain 302 continues to drive, it can drive the seed scoops 401 to rise and cause the rollers 408 on both sides to move towards the seed conveying chain 302. When the curved rods 502 abut against each other, the rollers 408 roll on the surface of the curved rods 502, which drives the moving column 407 to slide in the square tube 406. This causes the two curved clamps 413 in the seed trough 403 to move closer to each other and clamp a single seed potato. By setting a compression spring 411 between the moving column 407 and the sleeve column 412, excessive compression force can be avoided, which can seriously damage the seed potato and affect its subsequent growth. Then, the seed spoon 401 will move to the top horizontal position of the seed dispensing chain 302. At this time, the seed spoon 401 will maintain a vertical conveying state. In this way, the excess seed potatoes in the seed spoon 401 will roll to the outside under the action of gravity. This allows the excess seed potatoes to be cleaned while keeping one seed potato in the seed trough 403, thereby reducing the replanting rate of the planter and improving the cleaning effect of the seed cleaning device.

[0038] Example 1

[0039] like Figure 7 As shown, in this embodiment, the front end of the seed spoon 401 is provided with multiple bionic claws 405 at equal intervals. The bionic claws 405 have a height of 4-5mm, a thickness of 2-5mm, and a width of 3-6mm.

[0040] In this embodiment, by providing a bionic claw 405 at the front end of the seed spoon 401, a single seed potato will not detach from the seed spoon 401 under the vibration of the vibration mechanism 100 and the brushing of the seed cleaning mechanism 200.

[0041] like Figure 8 As shown, in this embodiment, multiple anti-detachment grooves 414 are provided at equal intervals on the inner wall of the arc-shaped clamp 413.

[0042] In practice, by providing an anti-detachment groove 414 on the inner wall of the arc-shaped clamp 413, the friction of the inner wall of the arc-shaped clamp 413 can be increased, preventing the arc-shaped clamp 413 from separating from the seed potato and thus avoiding the situation of missing seeding.

[0043] Example 2

[0044] like Figure 5-6 As shown, in this embodiment, the seed metering and conveying mechanism 300 includes four sprockets 301, with a seed metering chain 302 meshing between the four sprockets 301. A seed scoop 401 is connected to the seed metering chain 302 via a fixing member 402. A drive shaft 303 is fixedly connected to each sprocket 301. Fixing plates 304 are provided on both sides of each sprocket 301. A sliding groove 305 is provided in each fixing plate 304, and an adjusting plate 306 is slidably connected to the sliding groove 305. A fixed adjustment plate 306 is located at the center of the adjusting plate 306. A sliding seat 307 is fixedly connected, and a U-shaped plate 308 is slidably sleeved on the outside of the sliding seat 307. The U-shaped plate 308 is fixedly connected to the side wall of the seed box 1. Locking pins 309 that abut against the U-shaped plate 308 are screwed onto both sides of the sliding seat 307. Compression springs 310 are fixedly connected to both ends of the adjusting plate 306. A connecting block 311 that is slidably connected to the end of the compression spring 310 is fixedly connected to the end of the compression spring 310. The sprocket 301 is rotatably connected to the connecting block 311.

[0045] In practice, the sliding seat 307 is moved to the position in the U-shaped plate 308, and then the locking pin 309 is used to lock the sliding seat 307. The sliding seat 307 can drive the adjusting plate 306 to move, so that the two ends of the adjusting plate 306 can drive the compression spring 310 and the connecting block 311 to move. The position of the sprocket 301 can be adjusted through the connecting block 311, thus adjusting the tension of the seed metering chain 302. When the seed metering chain 302 is tighter, the vibration effect generated by the vibration mechanism 100 has a greater impact on the seed spoon 401, and vice versa. Thus, the tension of the seed metering chain 302 can be adjusted as needed.

[0046] Example 3

[0047] like Figure 9-11As shown, in this embodiment, the sweeping mechanism 500 includes two L-shaped abutments 501 fixedly connected to the seed box 1. Rollers 408 slide against the L-shaped abutments 501. Arc-shaped rods 502 are fixedly connected to the ends of both L-shaped abutments 501. Side baffles 506 are fixedly connected to opposite sides of both L-shaped abutments 501. A semi-circular cover 505 is fixedly connected between the two L-shaped abutments 501. A support frame 512 is fixedly connected to the L-shaped abutments 501. A rotating shaft 513 is rotatably connected to the support frame 512. A bevel gear 511 is fixedly connected to one end of the rotating shaft 513. A bevel gear 510 is meshed with one side of the bevel gear 511. A synchronous pulley 509 is fixedly connected to the center of the bevel gear 510. One end of a synchronous belt 508 is sleeved on the synchronous pulley 509. The other end of the synchronous belt 508 is sleeved with a drive shaft 3. The synchronous pulley 507 is fixedly sleeved in phase 3. The other end of the shaft 513 is fixedly connected to a disc 514. One end of the connecting rod 515 is rotatably connected to the side wall of the disc 514. The other end of the connecting rod 515 is rotatably connected to a sliding column 516. A limit ring 517 is slidably sleeved on the outside of the sliding column 516. Limit blocks 518 are fixedly connected to both sides of the sliding column 516. A U-shaped frame 522 is fixedly connected between the top ends of the two L-shaped abutments 501. A swing plate 519 is rotatably connected to the U-shaped frame 522. A limit groove 520 is opened in the swing plate 519 and is slidably embedded in the limit block 518. Multiple elastic brushes 521 are fixedly arranged at equal intervals at the bottom of the swing plate 519. A recovery plate 503 is fixedly connected to the L-shaped abutments 501 on both sides of the elastic brushes 521. A baffle 504 is fixedly connected to the recovery plate 503.

[0048] In practical implementation, the ground wheel drives the drive shaft 303 and the first synchronous pulley 507 to rotate. The first synchronous pulley 507, under the action of the synchronous belt 508, drives the second synchronous pulley 509 to rotate as well. The second synchronous pulley 509 drives the first bevel gear 510 and the second bevel gear 511 to mesh and rotate. Then, the first rotating shaft 513 drives the disc 514 to rotate. The disc 514 drives the connecting rod 515 to swing, and one end of the connecting rod 515 drives the sliding column 516. The sliding block 518 at the end of the sliding column 516 slides back and forth in the limiting ring 517, allowing it to slide back and forth in the limiting groove 520. This drives the swing plate 519 to swing back and forth on its bottom elastic brush 521. The multiple elastic brushes 521 can sweep and clean the seed potatoes that roll off the seed spoon 401 when it is in a vertical position, preventing the seed potatoes from accumulating on the chain and causing conveying jams. The elastic brushes 521 can also sweep the seed potatoes on the chain to the recycling plates 503 on both sides. The upper part, the recycling plate 503, is an inclined arc-shaped plate, so the seed potatoes will roll down along the arc surface of the recycling plate 503 back into the seed box 1. This allows for the recycling of excess seed potatoes while cleaning the seed box, thus saving agricultural resources. A baffle 504 is provided on the surface of the recycling plate 503 to prevent the recycled seed potatoes from falling into the seed scoop 401. A cylindrical protective structure is formed between the two L-shaped abutments 501 by a semi-circular cover 505 and side baffles 506. When the spoon 401 is flipped to face the ground, the vibration of the chain may cause the arc-shaped clamp 413 to lose its grip on the seed potato, which will fall into the receiving spoon 404 in the seed clamping mechanism 400 below. At this time, the cylindrical protective structure can prevent the seed potato from falling to the outside. When the roller 408 and the L-shaped abutment 501 on the seed clamping mechanism 400 separate, the seed spoon 401 will rotate and then plant a single seed potato into the furrow, so that the planter can complete precision planting.

[0049] Example 3

[0050] like Figure 1 As shown, in this embodiment, the vibration mechanism 100 includes a motor support 101 fixedly connected to the side wall of the seed box 1. A vibration motor 103 is fixedly sleeved in the motor support 101. An eccentric wheel 104 is fixedly connected to the output end of the vibration motor 103. An adjusting plate 102 is fixedly connected to the bottom end of the motor support 101 through a connecting pin. A U-shaped groove is provided on the adjusting plate 102, and an adjusting bolt is provided in the U-shaped groove.

[0051] In practice, the output of the vibration motor 103 in the vibration mechanism 100 will drive the eccentric wheel 104 to rotate, which will cause the seed metering chain 302 and multiple seed scoops 401 to vibrate. This will shake the seed potatoes piled on the seed scoops 401 off, reducing the pressure of subsequent seed cleaning.

[0052] Example 4

[0053] like Figure 4 As shown, in this embodiment, the seed cleaning mechanism 200 includes a mounting column 201. A motor support 202 is fixedly connected to the side wall of the mounting column 201. A seed cleaning motor 203 is fixedly installed in the motor support 202. A base 204 is fixedly connected to the output end of the seed cleaning motor 203. Four elastic seed brushes 205 are arranged around the base 204. The elastic seed brushes 205 are 80-100mm long, 25-30mm wide, and made of nylon.

[0054] In practice, the output of the seed cleaning motor 203 drives the base 204 to rotate, which in turn drives the four elastic seed brushes 205 on the side wall of the base 204 to rotate. The elastic seed brushes 205 can brush and clean the excess seed potatoes in the seed spoon 401, which helps to improve the seed cleaning efficiency of the device.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
