Description

Technical Field

[0001] This application relates to the technical field of seeding equipment, and particularly relates to a disassembly and assembly structure for a brush of a seeder. Background Art

[0002] A push-type seeder is a planting machine that uses seeds as the seeding object. It is commonly used for seeding crops in small plots, replacing traditional manual seeding, and has the characteristics of high efficiency and labor saving.

[0003] In the prior art, a push-type seeder includes a housing, a seed separating assembly, and a feeding tray. A seed inlet is formed on the housing. The seed separating assembly includes a seed-taking wheel, a brush, and a driving wheel. The seed-taking wheel and the brush are installed inside the housing. Seed-taking grooves are formed on the circumferential surface of the seed-taking wheel. The outer circumference of the brush abuts against the outer circumference of the seed-taking wheel to form a seed outlet. The feeding tray is sleeved on the circumferential side of the housing and communicates with the seed outlet. The driving wheel is installed outside the housing and is drivingly connected to the seed-taking wheel. The driving wheel abuts against the feeding tray and rotates as the feeding tray rotates.

[0004] The brush is used to sweep away the redundant seeds in the seed-taking grooves so that only one seed is stored in each seed-taking groove. The outer circumference of the brush abuts against the seed-taking wheel and the seeds for a long time, which easily causes grooves to appear on the outer circumference of the brush, resulting in the disappearance of the abutting effect of the brush on the seed-taking wheel, making it difficult for the brush to effectively sweep away the redundant seeds in the seed-taking grooves and affecting the use effect of the seeder. Currently, the brush of the seeder is installed inside the housing and cannot be directly replaced. The whole seeder needs to be disassembled to replace the brush, and the operation is relatively cumbersome. Utility Model Content

[0005] In order to facilitate the replacement of the brush and improve work efficiency, this application provides a disassembly and assembly structure for a brush of a seeder.

[0006] A disassembly and assembly structure for a brush of a seeder provided by this application adopts the following technical solution:

[0007] A disassembly and assembly structure for a brush of a seeder includes a housing, a feeding tray, and a hole plug. The feeding tray is provided with a cavity. The housing is rotatably embedded in the cavity. The rotation axis of the housing coincides with the rotation axis of the feeding tray. The brush is rotatably connected to one side of the housing along the rotation axis of the housing. The rotation axis of the brush is parallel to the rotation axis of the housing. A through hole is provided on one side of the cavity close to the brush along the rotation axis of the housing. The through hole communicates with the outside. The hole plug is connected to the feeding tray and covers the through hole.

[0008] By adopting the above technical solution, when the brush needs to be replaced, the hole plug is removed, and the through hole is rotated to align with the brush, so as to realize the replacement of the brush, improve work efficiency, enable the brush to effectively sweep away the redundant seeds in the seed-taking grooves, and ensure the use effect of the seeder.

[0009] Preferably, a fixing groove is provided at the hole wall of the through hole close to the housing side. The fixing groove extends along the circumferential direction of the through hole. An embedding groove is provided at the groove wall on one side of the fixing groove along the circumferential direction of the through hole away from the housing side.

The sliding direction of the embedding block is parallel to the rotation axis of the housing. The embedding block is rotationally embedded in the fixing groove. The rotation axis of the embedding block coincides with the axis of the hole plug.

[0010] By adopting the above technical solution, the embedding block is slid axially along the housing axis and embedded into the embedding groove. When the embedding block is aligned with the fixing groove, the hole plug is rotated so that the embedding block is embedded into the fixing groove, realizing the axial fixation of the hole plug and the material feeding tray, reducing the possibility of the hole plug falling off during the use of the seeder, and preventing foreign matters from entering the cavity and damaging the internal components of the seeder, thereby improving the service life of the seeder.

[0011] Preferably, a plurality of the embedding blocks are provided. The plurality of embedding blocks are circumferentially spaced apart around the axis of the hole plug. The number of the embedding grooves and the fixing grooves is the same as that of the embedding blocks and they correspond one by one.

[0012] By adopting the above technical solution, a plurality of embedding blocks are provided to improve the connection stability between the hole plug and the material feeding tray, reduce the stress concentration phenomenon at the connection between the embedding block and the hole plug, reduce the possibility of fracture at the connection between the embedding block and the hole plug, and improve the service life of the hole plug.

[0013] Preferably, a convex strip is connected to the surface of the hole plug away from the housing.

[0014] By adopting the above technical solution, the convex strip is provided to facilitate the user to drive the hole plug to rotate through the convex strip, realizing the rotation of the embedding block into or out of the fixing groove, and improving the comfort of the user.

[0015] Preferably, an avoidance groove is provided on the outer periphery of the hole plug. A contact strip is connected to the groove wall of the avoidance groove.

The first chamfer and the second chamfer are respectively located at both ends of the contact block. When the hole plug rotates and locks, the contact strip abuts against the second chamfer. When the hole plug rotates and unlocks, the contact strip abuts against the first chamfer.

[0016] By adopting the above technical solution, the contact block and the contact strip are provided to cooperate with each other. After the hole plug rotates in place, the circumferential fixation of the hole plug and the material feeding tray is realized, reducing the possibility that the hole plug rotates during the use of the seeder, causing the embedding block to disengage from the fixing groove and the hole plug to disengage from the material feeding tray.

[0021] Preferably, it further includes a connecting part and a limiting part. One end of the connecting part is connected to the surface of the mounting plate away from the housing. The limiting part is connected to the other end of the connecting part. The limiting part is located on the side of the connecting part close to the mounting hole. The surface of the limiting part close to the mounting plate is used to abut against the surface of the disassembly and assembly plate away from the housing. A groove is provided on the outer periphery of the disassembly and assembly plate for the limiting part to pass through.

[0022] By adopting the above technical solution, a connecting part and a limiting part are provided. The limiting part abuts against the disassembly and assembly plate, realizing the relative fixation of the disassembly and assembly plate and the mounting plate, reducing the dropping of the disassembly and assembly plate during use, resulting in the disappearance of the limit on the brush and the disappearance of the effect of the brush. A groove is provided. When the disassembly and assembly plate needs to be taken out, rotate the disassembly and assembly plate to align the groove with the limiting part, realizing the limiting contact of the limiting part with the disassembly and assembly plate.

[0023] Preferably, there are several connecting parts. The several connecting parts are circumferentially and evenly distributed around the axis of the disassembly and assembly plate. The number of the limiting parts and the grooves is the same as that of the connecting parts and they correspond one by one.
