Description

Technical Field

[0001] This utility model relates to the field of cabbage harvesting technology, specifically a leaf-peeling mechanism for a cabbage harvester. Background Technology

[0002] Cabbage is one of the main vegetable varieties, but compared with grain production, the level of mechanization in vegetable production is relatively backward. For a long time, cabbage harvesting has still relied mainly on manual labor, which is characterized by low labor efficiency, high labor intensity, poor work quality, and high production costs.

[0003] In recent years, the applicant, together with the Nanjing Institute of Agricultural Mechanization of the Ministry of Agriculture and Rural Affairs, has jointly conducted research and development on cabbage harvesting machinery, and designed a series of cabbage harvesting machines. These include the cabbage harvester with patent number 2021101436874, a riding-type tracked cabbage harvester with patent number 202222949244.7, and a hand-held self-propelled cabbage harvester with patent number 2022208712019. All of these machines harvest cabbage through a header assembly and conveying mechanism, among other components.

[0004] However, the above mechanisms have the following drawbacks: the leaf-peeling mechanisms all peel leaves by creating a speed difference between the leaf-peeling roller and the conveyor belt, but this structure has poor leaf-peeling results, cannot peel leaves well, and the leaf-peeling time is short, so the cabbage is sent out by the conveyor belt before the leaves are peeled in time. Summary of the Invention

[0005] The purpose of this utility model is to provide a leaf-peeling mechanism for a cabbage harvester to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leaf-peeling mechanism for a cabbage harvester, characterized in that: the cabbage leaf-peeling mechanism includes brush rollers 3 and conveyor rollers 12 arranged adjacent to each other. The brush rollers 3 and conveyor rollers 12 are coaxial with and fixed to rotating shaft 1 2 and rotating shaft 2 11, respectively. The same side of rotating shaft 1 2 and rotating shaft 2 11 are respectively connected to separate right-angle gearboxes 5, and the other side is supported on support tube 1 through bearing seats. The two right-angle gearboxes 5 are connected in series through transmission shaft 6 and fixed in mounting frame 4, and are powered by motor reducer unit 7. A support guide plate 14 is provided below the brush rollers 3 and conveyor rollers 12.

[0007] The conveyor roller 12 is provided with a forward hinge 13 of the same length as the conveyor roller 12.

[0008] The conveyor roller 12 is provided with a forward hinge 13 and a reverse hinge 15 of equal length.

[0009] The motor reducer 7 is fixed above the mounting frame 4 by a bracket, and the output end of the motor reducer 7 is provided with a drive sprocket 8, and the drive shaft 6 is provided with a driven sprocket 10. The drive sprocket 8 and the driven sprocket 10 are connected by a chain 9.

[0010] The diameter of the passive sprocket 10 is twice or more than twice the diameter of the active sprocket 8.

[0011] This utility model has the following beneficial effects: First, by changing the leaf-peeling mechanism to a brush roller and a conveyor roller, and placing the cabbage between the brush roller and the conveyor roller, the leaf-peeling efficiency and yield of cabbage are greatly improved by increasing the leaf-peeling time, increasing friction, and expanding the contact area; Second, bidirectional leaf peeling and discharge can be carried out as needed, thereby improving the discharge efficiency of cabbage.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1:

[0017] A leaf-stripping mechanism for a cabbage harvester includes support pipes 1 on both sides and a mounting frame 4, which are fixed together by plates. The mounting frame 4 contains two right-angle gearboxes 5 connected in series by a transmission shaft 6. The right-angle gearboxes 5 are respectively connected to a first rotating shaft 2 and a second rotating shaft 11. The other ends of the first rotating shaft 2 and the second rotating shaft 11 are fixed to the support pipes 1 by bearing seats. The mounting frame 4 also has a motor reducer 7 that drives the first rotating shaft 2 and the second rotating shaft 11 to rotate. The motor reducer 7 is fixed above the mounting frame 4 by a bracket. The output end of the motor reducer 7 has a drive sprocket 8, and the transmission shaft 6 has a driven sprocket 10. The drive sprocket 8 and the driven sprocket 10 are connected by a chain 9. When the motor reducer 7 rotates, it drives the first rotating shaft 2 and the second rotating shaft 2 to rotate simultaneously in the same direction, i.e., the brush roller 3 and the conveyor roller 12 rotate simultaneously in the same direction. The diameter of the passive sprocket 10 is twice or more than twice the diameter of the active sprocket 8. This reduces the output speed of the motor reducer 7, but increases the transmission torque, providing sufficient power for the brush roller 3 and the conveyor roller 12.

[0018] The conveyor roller 12 is provided with a forward hinge 13 of the same length as the conveyor roller 12, which can drive the cabbage to move in one direction and cooperate with the brush roller 3 to peel the leaves.

[0019] To prevent the cabbage from falling off during leaf peeling, a support guide plate 14 is provided below the brush roller 3 and the conveyor roller 12. The two sides of the support guide plate 14 are inclined surfaces away from the support tube 1 and the mounting bracket 4, so that the cabbage falls off from one side of the two sides. Example 2:

[0020] Based on Embodiment 1, the rest of the technical solutions remain unchanged, except that the continuous forward hinge 13 on the conveyor roller 12 is changed to half forward hinge 13 and half reverse hinge 15, so that the cabbage is changed from falling and outputting from one side to falling and outputting from both sides, which improves the efficiency of cabbage leaf peeling and conveying. Example 3:

[0021] A leaf-stripping mechanism for a cabbage harvester includes symmetrically arranged support tubes 1 on both sides and a mounting frame 4 located between the two support tubes 1. The three are fixed together by plates. The mounting frame 4 contains two right-angle gearboxes 5, which are connected in series by a drive shaft 6. The right-angle gearboxes 5 are respectively connected to a first rotating shaft 2 and a second rotating shaft 11. The first and second rotating shafts 2 and 11 pass through the right-angle gearboxes 5 and are symmetrically equal on both sides. The two ends of the first and second rotating shafts 2 and 11 are fixed by bearing seats. On the support tubes 1 on both sides, and on the mounting frame 4, there is a motor reducer 7 that drives the rotating shaft 1 2 and rotating shaft 2 11. The motor reducer 7 is fixed above the mounting frame 4 by a bracket, and the output end of the motor reducer 7 is equipped with a drive sprocket 8, and the drive shaft 6 is equipped with a driven sprocket 10. The drive sprocket 8 and the driven sprocket 10 are connected by a chain 9. When the motor reducer 7 rotates, it drives the rotating shaft 1 2 and rotating shaft 2 to rotate simultaneously in the same direction, that is, the brush roller 3 and the conveyor roller 12 rotate simultaneously in the same direction. The diameter of the driven sprocket 10 is 2 times or more than 2 times the diameter of the drive sprocket 8. This reduces the output speed of the motor reducer 7, but increases the transmitted torque, providing sufficient power for the brush roller 3 and the conveyor roller 12.

[0022] The conveyor rollers 12 on both sides are respectively provided with a forward hinge 13 and a reverse hinge 15. In order to prevent the cabbage from falling off when peeling leaves, a support guide plate 14 is provided below the brush roller 3 and the conveyor roller 12. The two sides of the support guide plate 14 are inclined surfaces away from the support tube 1 and the mounting frame 4, guiding the cabbage to fall off from both sides.
