[0002] Green onions are a traditional cash crop in my country, and harvesting green onions is a tedious task. Although my country ranks first in the world in terms of green onion planting area, total output and total export volume, my country's green onion harvesting machinery started late, and the harvesting method is still mainly manual harvesting and semi-machine and semi-manual harvesting, which greatly increases the operating cost, resulting in a decrease in the economic benefits of green onion planting, which directly affects people's enthusiasm for growing green onions.

[0003] There are two main problems with the green onion harvesting products on the market. First, the machine functions are relatively simple and can only complete some functions. Second, although some green onion harvesters have been mechanized, they are prone to damage the green onions during harvesting or mistakenly receive rotten, withered or diseased onions, resulting in lower overall harvest quality and increased subsequent screening costs.

DETAILED DESCRIPTION

[0019] like Figure 1-3 In the invention, a small intelligent green onion combine harvester is disclosed, comprising a loosening module 1, a clamping and transporting module 2, a shaking soil module 3, a defoliating module 4, a basket screening module 5 and a power distribution module 6 arranged on a mounting seat 7. The loosening module 1 and the power distribution module 6 are respectively arranged on both sides of the mounting seat 7. The clamping and transporting module 2 comprises a first frame 203, which is tilted on the mounting seat 7. Two clamping belts 202 are symmetrically arranged on the first frame 203. The two clamping belts 202 are used to pull the green onions out of the soil. The shaking soil module 3 and the defoliating module 4 are respectively arranged on the lower side and the upper side of the clamping belt 202. The basket screening module 5 is arranged below the end of the first frame 203 close to the power distribution module 6.

[0020] Working process: before starting the machine, adjust the height of the leaf removal module 4 to a suitable height according to the cutting requirements of the onion leaves, and ensure that the clutch of the two wheels 604 is in a closed state; after starting the machine, the whole machine moves forward slowly, and at the same time, the loosening knife 101 rotates to loosen the soil, and the green onions are pulled out of the soil by the clamping action of the clamping belt 202 of the clamping and transporting module 2, and then transported upward; then the roots of the green onions pass through the area of ​​the soil shaking module 3, and the soil at the roots of the green onions is beaten and removed by the soil shaking rod 305, and the green onions continue to be clamped and transported upward; when the green onion leaves pass through the area of ​​the leaf removal module 4, the excess green onion leaves are sheared by the blade 406; at the same time, before the green onions enter the clamping and transporting module 2 The front camera 501 on the screening module 5 identifies the quality of the green onions. After the root soil and green onion leaves are processed, the green onions are about to be transported to the screening area. If the green onion leaves are found to be withered, spotted, rotten, etc. in the identification area, the signal will be delayed and transmitted to the steering gear 503 to control the basket 511 to move right, so that the green onions fall out of the basket 511. If they are identified as normal green onions, they will fall into the basket 511; when steering is required, the coupling 605 with the rear wheel shaft can be adjusted. If the left clutch is disconnected and the right is closed, that is, only the right wheel shaft rotates, the whole machine turns left, otherwise it turns right. If both wheels are closed or disconnected, the whole machine can move forward or stop.

[0021] The green onions are sequentially screened through the soil loosening module 1, the clamping and transporting module 2, the soil shaking module 3, the leaf removing module 4 and the screening module 5, and then enter the basket 511. The overall harvesting is fast, and the visual recognition of the camera 501 can better identify the position and state of the green onions, which is convenient for shaking the soil and beating, ensuring a better effect of shaking the soil. At the same time, the overall picking quality is controlled, and unqualified green onions are not put into the basket 511, which is convenient for subsequent packaging and reduces workload.

[0022] like Fig.12In the figure, the bottom of the first frame 203 is fixed to the mounting base 7 by the first long bracket 12, the second long bracket 13, the first short bracket 14 and the second short bracket 15 respectively. The first long bracket 12, the second long bracket 13, the first short bracket 14 and the second short bracket 15 ensure the stable operation of the first frame 203. The overall structure has good rigidity and strong bearing capacity, and the inclined state of the first frame 203 is firmly supported.

[0023] like Figure 4-5 In the preferred scheme, the loosening module 1 includes two first transmission shafts 104 arranged opposite to each other, and the two ends of the first transmission shaft 104 are respectively meshed and connected with the second transmission shaft 105 and the loosening knife 101 through two first bevel gears 102, the second transmission shaft 105 is connected to the first motor 9, and the first transmission shaft 104 is fixed by the first bearing seat 103 and the mounting seat 7.

[0024] The loosening knife 101 is assembled from four evenly arranged arc plates, which are inclined toward one side of the central axis of the clamping and transporting module 2 to facilitate efficient loosening of the soil. During the rotation of the loosening knife 101, the soil on both sides of the green onion can be turned and pushed well, making it easier for the clamping belt 202 of the clamping and transporting module 2 to pull the green onion out of the soil.

[0025] like Figure 6-7 In the preferred solution, a plurality of idler wheels 204 are symmetrically distributed in the middle of the first frame 203, the clamping belt 202 on one side is wound around the flat pulley 201, the idler wheel 204 and the first pulley 216, and the clamping belt 202 on the other side is wound around the flat pulley 201, the idler wheel 204 and the second pulley 217, and the baffle 210 is fixed to the first frame 203 by the baffle bracket 211, and the baffle 210 is used to control the clamping range of the clamping belt 202; A tension spring rod 205 is provided on the first frame 203 located on one side of the second pulley 217. The tension spring rod 205 is connected to a tension spring lever 207 through a plurality of tension springs 206. The tension spring lever 207 is connected to the first frame 203 through a lever bracket 208 and a slider 209. The lever bracket 208 is fixedly connected to the first frame 203. The slider 209 is slidably connected to the first frame 203. The end of the slider 209 is fixed to the idler wheel 204. The front end of the baffle 210 is provided with an inclination angle, and is tilted toward both sides to form an opening, so as to facilitate the feeding of green onion leaves, so that the subsequent leaf removal module 4 can shear the green onion leaves.

[0026] The clamping gap between the two relative clamping belts 202 can be adaptively changed according to the size of the green onions. When clamping larger green onions, the clamping belt 202 on one side of the second pulley 217 is squeezed by the green onions, thereby pushing the slider 209 to move outward. At this time, the tension spring lever 207 rotates around the lever bracket 208, and the tension spring 206 is stretched. When the green onions are transported, the stretched tension spring 206 returns to its initial state under the action of the restoring force.

[0027] In the preferred solution, a second frame 218 is provided at the end of the first frame 203, a first pulley 216 and a second pulley 217 are rotatably arranged on the second frame 218, handrails 213 are respectively arranged on both sides of the lower part of the second frame 218, a second motor 10 is arranged on the handrail 213 close to the first pulley 216, and an output shaft of the second motor 10 is connected to the first pulley 216 via a rotating wheel 219 and two speed regulating belts 220; A second bearing seat 212 is further provided on the upper part of the second frame 218, a third transmission shaft 214 is passed through the middle of the second bearing seat 212, two second bevel gears 215 are symmetrically provided in the middle of the third transmission shaft 214, and the two second bevel gears 215 respectively drive the first pulley 216 and the second pulley 217 to rotate in opposite directions through the second bevel gears 215.

[0028] The second frame 218 and the second bevel gear 215 can ensure that the first pulley 216 and the second pulley 217 rotate in opposite directions, so as to transport the green onions from the lower position of the first frame 203 to the higher position. The handrail 213 is convenient for the operator to support and control the direction.

[0029] like Figure 8 In the preferred solution, the soil shaking module 3 includes a crank shaft 301, one side of the crank shaft 301 is connected to the second transmission shaft 105, and the other side of the crank shaft 301 is provided with a first crank 302, and the first crank 302 is provided with a round rod 322, and the round rod 322 and the slot slider 303 are slidably connected, and the round rod 322 is located in the waist round groove 325 on the slot slider 303, and the vertical plate 323 on the upper part of the slot slider 303 is slidably connected to the slide rail bracket 304, and the bottom of the slide rail bracket 304 is fixed to the mounting seat 7; A soil shaking rod bracket 306 is also provided, and a sleeve 308 is sleeved on the soil shaking rod bracket 306. Two soil shaking rods 305 are parallelly provided on the sleeve 308. A lever 307 is provided on one side of the sleeve 308.

The lever 307 and the constraint groove 324 are clamped together, and the roots of the green onions are beaten by the swing of the two soil shaking rods 305.

[0030] When the first crank 302 rotates, it drives the slotted slider 303 to move back and forth up and down in the slide rail of the slide rail bracket 304, thereby driving the soil shaking rod 305 to swing back and forth around the fulcrum of the soil shaking rod bracket 306 to achieve soil shaking. The soil shaking rods 305 on both sides swing left and right to slap the position of the onion close to the root system, slapping the attached soil, and the soil shaking is efficient and effective.

[0031] like Fig. 9 In the preferred embodiment, the leaf removal module 4 includes a square shaft 401, which is inserted in the middle of the square hole shaft 8, and the square hole shaft 8 is rotatably arranged on the first frame 203. The bottom of the square hole shaft 8 is connected to the second motor 10. A transmission box 410 is provided on the top of the square shaft 401. A large gear 402 and a small gear 403 are meshed and connected in the transmission box 410. The bottom of the large gear 402 is fixed to the square shaft 401, and the top of the small gear 403 is connected to the second crank 404. The second crank 404 is connected to the blade 406 through the first connecting rod 405, the blade 406 is inserted into the fixed sleeve 411, the blade 406 and the fixed sleeve 411 are slidably connected, a knife holder 407 is provided on one side of the fixed sleeve 411, the knife holder 407 is supported at the bottom of the knife holder 407, a vertical rod 412 is provided at the bottom of the fixed sleeve 411, the vertical rod 412 is connected to the first frame 203 through a height adjustment rod 409, and a locking bolt 408 for adjusting the height of the vertical rod 412 is also provided on one side of the height adjustment rod 409.

[0032] The square hole shaft 8 rotates with the second motor 10, and the second crank 404 rotates, driving the first connecting rod 405 to swing, so that the upper blade 406 moves back and forth, while the tool holder 407 is fixed, and the relative movement of the blade 406 and the tool holder 407 cooperates to realize the shearing action. After loosening the locking bolt 408, the tool holder 407 can move up and down in the hole of the height adjustment rod 409 to adjust the shearing position.

[0033] like Fig.10 In the preferred solution, the screening module 5 includes a steering gear bracket 502, the steering gear bracket 502 is fixed to the mounting seat 7, a steering gear 503 is provided on the upper part of the steering gear bracket 502, the steering gear 503 is connected to the basket moving platform 509 through the third crank 504 and the second connecting rod 505 in sequence, the third crank 504 and the second connecting rod 505 are hinged, the second connecting rod 505 and the basket moving platform 509 are hinged, and the basket moving platform 509 is detachably provided with a basket 511, Optical axes 512 are symmetrically provided on both sides of the lower part of the basket moving platform 509, and linear bearings 510 are provided on the optical axes 512.

A basket storage rack 11 for hanging the basket 511 is also provided on one side of the first frame 203.

[0034] The visual direction of camera 501 is the onion feeding entrance. When the onions enter the loose soil area, camera 501 will identify the color of the onion leaves and whether there are spots, withering, rot and other characteristics. When camera 501 identifies that the quality of the onions is poor, camera 501 will delay transmitting a signal to allow servo 503 to control the basket moving platform 509 to move outside the onion landing point through the crank slider mechanism. The servo 503 is actuated to drive the crank slider mechanism to move the basket moving platform 509 to the right. Since the landing point of the onions is fixed after being transported by the clamping belt, the basket 511 can avoid the landing point, thereby discarding the onions of poor quality.
