[0020] Compared with the prior art, the beneficial effects of the contour-following floating pickup and vibration soil removal device provided by the present invention are:

[0021] This invention provides a contour-following floating collection and vibration soil removal device. In this device, during the straw processing process, a tractor is attached to a traction frame, and the device moves forward with the tractor using its wheels. Two floating collection structures are located on both sides of the traction frame at an angle, which can collect the straw from both sides to the middle. Then, the second motor of the contour-following collection structure drives the collection plate assembly to move through the contour-following fingers, collecting the straw that has been collected between the two floating collection structures into the soil removal and crushing structure. The soil removal and crushing structure removes soil and crushes the straw. In the floating collection structure, the first motor drives the active wheel to rotate, which in turn drives multiple collection components to rotate. The driven wheel rotates together with the active wheel. It can be understood that the output shaft of the first motor passes through the eccentric wheel but is not at the center of the eccentric wheel. That is, the driven wheel and the active wheel are misaligned. Under the action of the driven wheel, the eccentric connecting rod and the connecting shaft, the direction of the roller brush on the collection component is always downward during the rotation of the active wheel. This can improve collection efficiency while reducing the weight and cost of the device.

[0022] This contour-following floating pickup and vibration soil removal device, combined with the actual needs of crop straw processing for straw collection, can achieve efficient straw collection, efficient soil removal, and is applicable to a wide range of straw collection effects.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0039] See Figure 1-9This invention provides a contour-following floating pickup and vibration soil removal device. The device includes a traction frame 1, two floating collection structures 2, a soil removal and crushing structure 3, and a contour-following collection structure 4. The two floating collection structures 2 are located on both sides of the traction frame 1 and are arranged at an angle. Each floating collection structure 2 includes a support 201, a wheel 202, a first motor 203, a driving wheel 204, a driven wheel 205, an eccentric wheel 206, a turntable 207, multiple eccentric connecting rods 208, multiple connecting shafts 209, and multiple collection components. The traction frame 1 is fixedly connected to the support 201. The wheel 202 is rotatably mounted on the support 201. The first motor 203 and the eccentric wheel 206 are both fixedly mounted on the support 201. The output shaft of the first motor 203 rotatably passes through the eccentric wheel 206 and is fixedly connected to the center of the driving wheel 204. The driven wheel 205 is rotatably mounted on the eccentric wheel 206. Multiple eccentric connecting rods 208 and 209 are connected to the eccentric wheel 204. 8. Multiple connecting shafts 209 and multiple collecting components are arranged one-to-one. The collecting components include collecting rods 210 and multiple roller brushes 211. The multiple roller brushes 211 are spaced apart on the collecting rods 210. The eccentric connecting rods 208 are evenly distributed along the circumference of the driven wheel 205. One end of the eccentric connecting rods 208 is rotatably connected to the driven wheel 205, and the other end is rotatably connected to one end of the connecting shafts 209. The connecting shafts 209 are rotatably inserted through the driving wheel 204. The other end of the connecting shafts 209 is fixedly connected to one end of the collecting rods 210. The other end of the collecting rods 210 is rotatably connected to the turntable 207. The soil removal and crushing structure 3 is fixedly connected to the traction frame 1 and is used to remove soil and crush straw. The contour collecting structure 4 includes a second motor 401, contour fingers and a collecting plate assembly. The second motor 401 drives the collecting plate assembly to move through the contour fingers so as to collect the straw that has been collected between the two floating collecting structures 2 into the soil removal and crushing structure 3.

[0040] In this contour-following floating collection and vibratory soil removal device, during the straw processing process, the tractor is connected to the traction frame 1. The device moves forward with the tractor using wheels 202. Two floating collection structures 2 are located on both sides of the traction frame 1 at an angle, which can collect all the straw within the working width to the middle. Then, the second motor 401 of the contour-following collection structure 4 drives the collection plate assembly to move through the contour-following fingers, collecting the straw that has been collected between the two floating collection structures 2 into the soil removal and crushing structure 3. The soil removal and crushing structure 3 removes soil and crushes the straw. In the floating collection structure 2, the first motor 203 drives the drive wheel 204 to rotate, and the drive wheel 204 drives multiple collection components to rotate. The driven wheel rotates with the drive wheel 204. It can be understood that the output shaft of the first motor 203 passes through the eccentric wheel 206 but is not at the center of the eccentric wheel 206, that is, the driven wheel and the drive wheel 204 are misaligned. The driven wheel 205 rotates relative to the eccentric wheel 206. Under the action of the driven wheel 205, the eccentric connecting rod 208 and the connecting shaft 209, the direction of the roller brush 211 on the collecting assembly is always downward during the rotation of the driving wheel 204, which can improve the collecting efficiency while reducing the weight and cost of the device.

[0041] This contour-following floating pickup and vibration soil removal device, combined with the actual needs of crop straw processing for straw collection, can achieve efficient straw collection, efficient soil removal, and is applicable to a wide range of straw collection effects.

[0042] In this embodiment, the roller brush 211 includes a brush body 2111, a brush head 2112 and a plurality of elastic components. The brush body 2111 is fixedly disposed on the collecting rod 210, and the brush head 2112 is located outside the brush body 2111. The brush body 2111 and the brush head 2112 are connected by elastic components.

[0043] Since the brush body 2111 and the brush head 2112 are connected by an elastic component, the distance between the brush head 2112 and the brush body 2111 will decrease due to the compression of the elastic component, thereby changing the collection height according to different ground heights, making it suitable for various terrains.

[0044] In this embodiment, the elastic component includes a spring 2113 and a telescopic rod 2114. The two ends of the telescopic rod 2114 are respectively fixedly connected to the brush body 2111 and the brush head 2112. The spring 2113 is sleeved on the telescopic rod 2114, and the two ends of the spring 2113 are respectively fixedly connected to the brush body 2111 and the brush head 2112.

[0045] In this embodiment, the roller brush 211 further includes two baffles 2115, which are located on both sides of the brush body 2111. One end of each baffle 2115 is fixedly connected to the brush body 2111, and the other end is fixedly connected to the brush head 2112. An elastic component is located between the two baffles 2115. The baffles 2115 prevent straw from entering the inner wall of the roller brush 211 and clogging its interior.

[0046] In this embodiment, the soil removal and crushing structure 3 includes a housing 301, a soil removal cover 302, a crushing component, and a discharge port 303. The housing 301 is fixedly connected to the traction frame 1. The soil removal cover 302 is located inside the housing 301 and is connected to the housing 301 through a shock absorber 308. The crushing component is located inside the soil removal cover 302, and the discharge port 303 is located in the housing 301.

[0047] The lower part of the soil-removing cover 302 has multiple arrayed circular holes. After the straw is picked up by the contour-following collection structure 4 and placed inside the soil-removing cover 302, the contour-following floating pickup and vibrating soil-removing device will vibrate when it moves on uneven ground, causing the straw to shake off the dust, which is then discharged from the circular holes of the soil-removing cover 302. To prevent excessive vibration, a shock absorber 308 is provided between the soil-removing cover 302 and the housing 301 to reduce the vibration amplitude. In this embodiment, there are multiple shock absorbers 308.

[0048] In this embodiment, buffer grooves 307 are provided on both sides of the housing 301, and the two ends of the soil removal cover 302 are respectively located in the two buffer grooves 307. The soil removal cover 302 moves between the upper and lower walls of the buffer grooves 307, and the soil removal cover 302 vibrates up and down within the range of the buffer grooves 307 to achieve the effect of soil removal.

[0049] In this embodiment, the crushing assembly includes a crushing shaft 304, a crushing spiral blade 305, and a crushing knife 306. The crushing spiral blade 305 and the crushing knife 306 are both fixedly mounted on the crushing shaft 304, and the crushing shaft 304 is rotatably mounted on the housing 301.

[0050] The external output power is transmitted to the crushing shaft 304 through the sprocket. The crushing shaft 304 drives the crushing spiral blades 305 and the crushing knife 306 to rotate. The crushing spiral blades 305 transport the straw to the side close to the crushing knife 306. The toothed crushing knife 306 further crushes the straw. Finally, the crushed straw is discharged from the discharge port 303.

[0051] It is understandable that there are multiple shredder blades 306, which are evenly arranged along the circumference of the shredder shaft 304.

[0052] In this embodiment, the contoured finger includes a finger base 402, a screw 403, a drive shaft 404, a drive arm 405, a connecting plate 406, and a connecting rod assembly. The finger base 402 is fixedly mounted on the housing 301, and a second motor 401 is fixedly mounted on the finger base 402. The second motor 401 is connected to the screw 403 via a transmission structure. The screw 403 is rotatably mounted on the finger base 402. The drive shaft 404 has a threaded hole that is screwed to the screw 403. The drive shaft 404 is hinged to the drive arm 405. The connecting plate 406 is rotatably connected to the screw 403. Both the drive arm 405 and the connecting plate 406 are connected to the connecting rod assembly, and the connecting rod assembly is connected to the collecting plate assembly.

[0053] The contoured fingers on both sides of the housing 301 transmit power through the second motor 401 on the finger seat 402 and the transmission structure, driving the screw 403 to rotate. The drive shaft 404 is screwed to the screw 403, and the drive shaft 404 reciprocates along the screw 403. The drive shaft 404 drives the drive arm 405 to move, the drive arm 405 drives the connecting rod assembly to move, and the connecting rod assembly drives the collecting plate assembly to move. The collecting plate assembly can grab the straw upwards and put the straw into the soil removal cover 302.

[0054] In this embodiment, the transmission structure includes a driving gear and a driven gear. The output shaft of the second motor 401 is fixedly connected to the driving gear, the driving gear meshes with the driven gear, and the driven gear is fixedly connected to the screw 403.

[0055] In this embodiment, the linkage assembly includes a first link 407, a second link 408, a third link 409, a fourth link 410, a fifth link 411, and a sixth link 412. One end of the first link 407, the connecting plate 406, and one end of the second link 408 are hinged together. The other end of the first link 407, the other end of the drive arm 405, and one end of the third link 409 are hinged together. The second link 408, the fifth link 411, and the sixth link 412 are all L-shaped and have inflection points. The other end of the third link 409 is hinged to the inflection point of the fifth link 411. One end of the fifth link 411 is hinged to the inflection point of the second link 408. The other end of the second link 408 is hinged to the fourth link 410. The other end of the fourth link 410 is hinged to one end of the sixth link 412. The inflection point of the sixth link 412 is connected to the other end of the fifth link 411. The collection plate assembly includes a first collection plate 413, a second collection plate 414, a third collection plate 415, a first collection shaft 416, a second collection shaft 417, a third collection shaft 418, and a fourth collection shaft 419. The two ends of the first collection shaft 416 are respectively connected to one end of the first collection plate 413 and the drive arm 405. The housing 301 is provided with an arc-shaped hole 3011, through which the first collection shaft 416 passes. The first collection plate 413 and the second collection plate 414 are both rotatably mounted on the second collection shaft 417. The inflection point of the fifth connecting rod 411 is connected to the second collection shaft 417. The second collection plate 414 and the third collection plate 415 are both rotatably mounted on the third collection shaft 418. The inflection point of the third collection shaft 418 is connected to the sixth connecting rod 412. The fourth collection shaft 419 is connected to the third collection plate 415 and the sixth connecting rod 412 respectively.

[0056] When the conformal finger drives the collecting plate assembly to collect the straw into the soil removal cover 302, the right end of the drive arm 405 is driven by the drive shaft 404 to move to the left along the screw 403. The left end of the drive arm 405 drives the first connecting rod 407 and the third connecting rod 409 to rotate. The second connecting rod 408 and the third connecting rod 409 then drive the fourth connecting rod 410 and the fifth connecting rod 411 to rotate. The fourth connecting rod 410 and the fifth connecting rod 411 then drive the sixth connecting rod 412 to rotate, thereby causing the connecting rod assembly to lift up in a manner similar to bending a finger. Through the first collecting shaft 416, the second collecting shaft 417, the third collecting shaft 418, and the fourth collecting shaft 419, the collecting plate assembly is also lifted up, thereby collecting the straw on the collecting plate assembly into the soil removal cover 302.

[0057] In this embodiment, the contour-following collection structure 4 further includes a straw-pushing plate 420, which is fixedly connected to the housing 301. A third collection plate 415 is located above the straw-pushing plate 420. When the straw is gathered to the middle, the straw-pushing plate 420 prevents the straw from piling up and guides the straw to move towards the collection plate assembly.

[0058] During operation, the tractor is connected to the traction frame 1, and the tractor moves forward via the wheels 202. As it moves forward, the first motors 203 of the two floating collection structures 2 start, driving the drive wheel 204 to rotate. The drive wheel 204 then drives multiple collection components to rotate. Under the action of the driven wheel 205, the eccentric connecting rod 208, and the connecting shaft 209, the roller brushes 211 on the collection components always face downwards during the rotation of the drive wheel 204, thus improving collection efficiency while reducing the weight and cost of the device. Two floating gathering structures 2 are located on both sides of the traction frame 1 and are set at an angle to each other. They can gather all the straw within the working width to the middle. Then, the contoured fingers on both sides of the shell 301 drive the screw 403 to rotate through the second motor 401 on the finger seat 402 via the transmission structure. The drive shaft 404 is screwed to the screw 403 and moves along the screw 403. The drive shaft 404 drives the drive arm 405 to move, the drive arm 405 drives the connecting rod assembly to move, and the connecting rod assembly drives the collecting plate assembly to move. The collecting plate assembly can grab the straw upward and put the straw into the soil removal cover 302. The lower part of the soil removal cover 302 has multiple arrayed circular holes. After the straw is picked up by the contour-following collection structure 4 and placed into the soil removal cover 302, the contour-following floating pickup and vibrating soil removal device will vibrate when it moves on uneven ground. The soil removal cover 302 moves between the upper and lower walls of the buffer grooves 307 on both sides of the housing 301, thereby shaking off the dust from the straw. The dust is discharged from the circular holes of the soil removal cover 302. To prevent excessive vibration, there is a shock absorber 308 between the soil removal cover 302 and the housing 301 to reduce the vibration amplitude. The external output power is transmitted to the crushing shaft 304 through a sprocket. The crushing shaft 304 drives the crushing spiral blades 305 and the crushing blades 306 to rotate. The crushing spiral blades 305 transport the straw to the side close to the crushing blades 306. The toothed crushing blades 306 further crush the straw. Finally, the crushed straw is discharged from the discharge port 303.
