Technical Field

[0001] This utility model relates to the field of harvester chain technology, and in particular to a corn harvester chain with a brush and a corn harvester. Background Technology

[0002] A corn harvester is an agricultural implement used to harvest corn when it is mature or nearly mature. Currently, conventional corn harvesters, when using chains to harvest corn, cause some corn kernels to fall off the cob and remain in the field, resulting in incomplete harvesting and reduced yield. This application addresses these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a corn harvester chain with a brush and a corn harvester. The chain is designed with a brush structure. During operation, the brush can lift up the scattered corn kernels, thereby increasing the harvest yield and solving the problem of reduced yield caused by scattered corn kernels falling into the field during corn harvesting.

[0004] To address the aforementioned problems, this utility model provides a corn harvester chain with brushes, comprising several inner chain links, U-shaped chain links, and K-shaped chain links. Each inner chain link includes an inner chain plate, a sleeve, and a roller. Each U-shaped chain link includes an outer plate A, a pin, a brush sleeve, and a brush A assembly, with the brush A assembly mounted on the brush sleeve and connected to the outer plate A. Each K-shaped chain link includes an outer plate B, an outer chain plate, and a brush B assembly mounted on the outer plate B. The brush A assembly and the brush B assembly together constitute an anti-kernel-drop module, where the bristles can intercept some corn kernels scattered on the corn cob, thereby increasing harvest yield.

[0005] According to one embodiment of the present invention, the brush A component and the brush sleeve are nested and snap-fit ​​connected, and the brush sleeve is connected to the outer plate A through a connector.

[0006] According to one embodiment of the present invention, the outer plate B and the brush B assembly are connected by a connector.

[0007] According to one embodiment of the present invention, the outer plate B is provided with a plug-in part, and the base of the brush B assembly is provided with a plug hole for the plug-in part to be inserted to achieve plug-in engagement.

[0008] In this solution, the brush sleeve enables the connection between brush A component and outer plate A. The outer plate B and the insertion holes and connectors on brush B component enable the connection between the two, thereby integrating the anti-particle-dropping module onto the chain without making significant structural changes to the existing chain structure.

[0009] According to one embodiment of the present invention, the brush B component is provided with several rows of bristles, including rows of long bristles and rows of short bristles.

[0010] According to one embodiment of the present invention, the brush B component is provided with three rows of bristles, including two rows of long bristles and one row of short bristles arranged in sequence, to improve the interception effect.

[0011] According to one embodiment of the present invention, the difference between the bristle length of the long bristle row and the bristle length of the short bristle row is 15mm.

[0012] According to one embodiment of the present invention, the long bristle row is arranged at an angle, and the short bristle row is arranged vertically, which further improves the interception effect.

[0013] According to one embodiment of the present invention, the bristle length of the long bristle row is equal to the bristle length in the brush A component.

[0014] A corn harvester includes a left chain and a right chain, both of which are the aforementioned corn harvester chains with brushes.

[0015] The beneficial effects of this utility model are that by adding brush A and brush B components to the traditional corn harvester chain, and by assembling brush A and brush B components with the chain in a simple and sturdy manner, the corn kernels scattered on the corn cob during harvesting can be intercepted by the brush bristles and move with the chain, which can effectively prevent most of the detached corn kernels from falling directly into the field, so that most of the detached corn kernels can also be harvested, thereby increasing the harvest yield.

[0024] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0025] A corn harvester chain with a brush, such as Figures 1-7 The whole is composed of a left chain 21 and a right chain 22. The L and R in the figure represent the parts on the left chain and the parts on the right chain, respectively. The left chain 21 and the right chain 22 have the same structure and are arranged symmetrically. They both include several inner chain links, U-shaped chain links with brushes and K-shaped chain links with brushes. Except for the brush assembly and the connection structure that cooperates with the brush assembly, the other structures are the same as or similar to the existing harvester chain structure.

[0026] Specifically, the inner link includes an inner link plate 3, a sleeve 6 and a roller 7 installed between two inner link plates 3; the U-shaped link includes an outer plate A1, a pin 2 passing through the sleeve 6, a brush sleeve 9, a brush A assembly 10, and a connector 11; the K-shaped link includes an outer plate B4, a pin 2, an outer link plate 5, a brush B assembly 8, and a connector 11, with the overall structure as follows: Figure 7 As shown, except for the brush assembly and the connecting structure that mates with the brush assembly, the other components are assembled and fitted according to the traditional chain structure.

[0027] In this embodiment, all connectors 11 are screws with hexagonal heads in a star shape. This design increases friction with the wrench during tightening, effectively preventing slippage during assembly and providing good anti-slip performance. In other embodiments, connectors 11 may also employ snap-fit ​​structures, pins, etc.

[0028] like Figure 6 The brush A component 10 consists of a base and brush bristles. The base is injection molded from PA6 material, which has good strength and impact toughness. The base has several holes, and the brush bristles are inserted into the holes on the base. After insertion, the brush bristles are firmly connected to the base.

[0029] The brush sleeve 9 has two threaded holes on its shoulder. After the brush A assembly 10 and brush sleeve are inlaid and assembled, they are then snapped into the outer plate A1 as a whole. Figure 1As shown in the partial sectional view at the location of connector 11, the screw passes through the two holes on the shoulder of the outer plate A1. Tightening the screw connects it to the threaded holes on the shoulders of the left and right brush sleeves, respectively.

[0030] The brush assembly B 8 consists of a base, long bristles, and short bristles. The base has a threaded hole 82, and the lower end of the base is injection molded into a shape with three rectangular holes to form an insertion hole 81. The outer plate B4 is provided with a plug-in part 41, which is inserted into the insertion hole 81 to achieve a plug-in fit. The brush assembly B 8 is snapped into the outer plate B4, and then screws are tightened from above to firmly connect the brush assembly B 8 and the outer plate B7.

[0031] The base of the brush component B is injection molded from PA6 material. The upper part of the base has three rows of holes into which brush bristles are inserted to form three rows of bristles, which are arranged as two rows of long bristles 83 and one row of short bristles 84.

[0032] Preferably, the difference between the bristle length of the long bristle row 83 and the bristle length of the short bristle row 84 is 10~20mm, preferably 15mm. In other embodiments, the difference can be adjusted according to the usage requirements.

[0033] The long bristle row 83 can be set at an angle or vertically.

[0034] In this embodiment, as Figure 1 The long bristle row 83 is inclined, and the short bristle row 84 is vertical.

[0035] Preferably, the bristle length of the long bristle row 83 is equal to the bristle length of the brush A component 10.

[0036] A corn harvester includes the aforementioned corn harvester chain with brushes.

[0037] Thanks to the above technical solutions, during harvesting, the corn kernels that fall off the corn cobs can be intercepted by the brush bristles and moved with the chain, effectively preventing most of the fallen corn kernels from falling directly into the field. This allows most of the fallen corn kernels to be harvested, thereby increasing the harvest yield.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments.
