DETAILED DESCRIPTION

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] refer to Figure 1 , a green onion harvester, comprising a frame mechanism 1, a harvesting mechanism 2, a soil removing mechanism 3, a sowing mechanism 4 and a soil covering mechanism 5;

[0024] The frame mechanism 1 includes a frame 11, and sliding assemblies 16 are slidably installed on both sides of the top of the frame 11. The sliding assemblies 16 can slide left and right on the top of the frame 11, so as to adjust the distance between the two sets of sliding assemblies 16. Track support frames 12 are movably installed on both ends of the rear side of the top of the frame 11, and the track support frames 12 are movably connected to the frame 11 by universal joints.

[0025] The harvesting mechanism 2 includes an encoder motor A21 slidably mounted on the rear side of the sliding assembly 16. The sliding assembly 16 is connected to the encoder motor A21 by a slider. The encoder motor A21 can slide up and down on the sliding assembly 16 to adjust the height. The rear wall of the encoder motor A21 is fixedly connected to the track support frame 12. Therefore, when the sliding assembly 16 is adjusting the spacing, it can drive the two groups of track support frames 12 to adjust the angle. The encoder motor A21 can drive the track support frame 12 to adjust the inclination angle by adjusting it up and down. A driven gear A23 is movably mounted on the rear side of the top of the track support frame 12. A driving gear A22 is installed on the top of the encoder motor A21. A harvesting crawler 24 is installed on the driving gear A22 and the driven gear A23.

[0026] In addition, a storage platform 13 is built on the top of the frame 11 and in front of the two sets of sliding components 16;

[0027] In this embodiment, when the vehicle is moving, the encoder motor A21 can drive the driving gear A22 to rotate, which can drive the harvesting tracks 24 to move. The two sets of harvesting tracks 24 move relative to each other, so the two sets of harvesting tracks 24 can be respectively located on both sides of the green onions for clamping, and the green onions can be pulled out by relative movement, thereby realizing the harvesting work. The pulled out green onions can fall into the storage platform 13 driven by the harvesting tracks 24.

[0028] refer to Figure 1-2 The soil removing mechanism 3 includes a movable seat 33 fixedly mounted on both ends of the rear side of the top of the frame 11 and slidably mounted thereon. The movable seat 33 is connected to the frame 11 through a slider. The movable seat 33 can be moved forward and backward on the frame 11 to adjust the position. A rotating shaft 31 is movably mounted laterally inside the two sets of movable seats 33. A soil removing wheel 32 is fixedly mounted in the middle of the rotating shaft 31, and the soil removing wheel 32 is arranged below the two sets of harvesting crawlers 24.

[0029] The movable seat 33 is provided with a servo motor inside, and the servo motor is connected to the rotating shaft 31 by transmission, and the servo motor can drive the rotating shaft 31 and the soil removing wheel 32 to rotate;

[0030] Secondly, the soil-removing wheel 32 is arranged under the two sets of harvesting crawlers 24. When the green onions are transported in the two sets of harvesting crawlers 24, the rotating soil-removing wheel 32 can beat the roots of the green onions to quickly remove the soil attached to them.

[0031] In this embodiment, the rotating shaft 31 and the soil removing wheel 32 can be adjusted to a suitable position below the two sets of harvesting crawlers 24 by sliding the movable seat 33 on the frame 11, and then the servo motor can be started to drive the soil removing wheel 32 to rotate to remove the soil at the root of the green onion during harvesting;

[0032] refer to Figure 1 The sowing mechanism 4 includes an encoder motor B41 fixedly mounted on one side of the top of the frame 11 and a driven gear B43 movably mounted on the front end of the inner side of the frame 11. The front end of the encoder motor B41 is driven by a driving gear B42, so the encoder motor B41 can drive the driving gear B42 to rotate. The driven gear B43 is slightly lower than the driving gear B42. A sowing crawler 44 is driven by the driving gear B42 and the driven gear B43.

[0033] A sowing platform 14 is built on one side of the frame 11 and close to the sowing crawler 44, and one side of the driving gear B42 is placed in the sowing platform 14;

[0034] In this embodiment, the encoder motor B41 can drive the sowing track 44 to rotate counterclockwise, so that the green onion seeds can be placed in the sowing platform 14. After starting the encoder motor B41, the sowing track 44 can drive the seeds to be evenly sown in the soil, thereby completing the sowing work.

[0035] refer to Figure 1 The soil covering mechanism 5 includes corner blocks 51 fixedly mounted on both sides of the front end of the frame 11, the angle of the corner block 51 is 30°, a soil covering device 52 is fixedly mounted on the top of the corner block 51, and two sets of soil covering devices 52 are symmetrically arranged;

[0036] The soil covering device 52 is composed of a soil covering plate. After the equipment moves to sow, the soil covering device 52 can scoop up the soil on both sides and cover the seeds, thereby completing the soil covering work after sowing.

[0037] refer to Figure 1-2 The bottom of the frame 11 is movably equipped with moving wheels 15 through couplings. The moving wheels 15 are mountain wheels to avoid slipping when traveling in the field.

[0038] Among them, drive motors 17 are symmetrically installed at the bottom of the frame 11 and on the inner sides of the moving wheels 15, and the output shafts of the two sets of drive motors 17 are respectively connected to the moving wheels 15 on both sides;

[0039] In this embodiment, the two sets of moving wheels 15 at the front end can be driven to rotate by the driving motor 17, and the harvester as a whole can be driven to move forward.

[0040] Working principle: When harvesting is required, the spacing between the two sets of sliding components 16 can be adjusted according to the size of the green onions, so as to adjust the angle of the two sets of harvesting crawlers 24 to make it suitable for green onions of different thicknesses. Then, the encoder motor A21 can be raised and lowered on the sliding component 16 to adjust the inclination of the harvesting crawler 24 to make it suitable for green onions of different heights. After the adjustment is completed, the drive motor 17 can be started to drive the moving wheel 15 to move forward. At the same time, the encoder motor A21 and the servo motor inside the movable seat 33 are synchronously turned on. After the encoder motor A21 is started, the harvesting crawler 24 can be driven Rotate, at this time, the two sets of encoder motors A21 rotate relatively, so that the two sets of harvesting crawlers 24 move relatively, and the green onions can be clamped and pulled out by the harvesting crawlers 24, and can be transported forward after being pulled out, and can fall into the storage platform 13 after being moved to the head, and in this process, the servo motor can drive the rotating shaft 31 and the soil removing wheel 32 to rotate, and the rotating soil removing wheel 32 can move the roots of the green onions, thereby shaking off the soil attached to the roots, so that the soil removal work can be completed synchronously during the harvesting process, and the movable seat 33 can be located on the frame 11 and slide forward and backward to adjust the position, so that it can be suitable for soil removal of green onions of different heights;

[0041] When sowing is needed, the seeds can be placed in the sowing platform 14 first, and then the encoder motor B41 is turned on when the equipment is moving. The encoder motor B41 can drive the driving gear B42 to rotate, and then the sowing crawler 44 can be driven to rotate counterclockwise. When the sowing crawler 44 rotates counterclockwise, the seeds in the sowing platform 14 can be moved into the soil. Then the equipment continues to move, and the soil covering device 52 at the rear can turn the soil over and cover the seeds, thereby completing the soil covering and forming ridges.

[0042] It is understandable that the encoder motor A, encoder motor B, servo motor and drive motor in the present invention can be driven by lithium batteries, and the encoder motor A, encoder motor B, servo motor and drive motor can be programmed and controlled by the main control system, and the control principle can be realized by existing control technology. The models of encoder motor A, encoder motor B, servo motor and drive motor are not limited to a single type and can be types that are available on the market and are suitable for the present invention.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
