Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly relates to a swather. Background Art

[0002] As an important agricultural machinery, the design and application of a swather originate from the need to innovate traditional crop harvesting methods. In early agricultural production, crop harvesting mainly relied on manual labor or simple tools, with low efficiency and high labor intensity. With the development of modern agricultural technology, mechanized operation has gradually become the key way to improve agricultural production efficiency and reduce the burden on farmers. The swather came into being under this background. It integrates functions such as cutting and laying, and can directly complete the cutting and neat laying of crops in the field, providing convenience for subsequent processes such as drying and threshing.

[0003] The Chinese utility model patent publication number CN218072456U discloses a walking type self-propelled forage swather, including a vertical cutter bar and a walking drive device. The vertical cutter bar includes a clutch type gearbox, a dividing device, a cutter assembly, a front conveying baffle, and a finger type conveying chain. Since the existing finger type conveying chain is a chain drive structure, the chain contacts the harvested materials during harvesting. Therefore, during actual use, plant stems and leaves will wind around the chain, resulting in an increase in transmission resistance. It is necessary to perform manual cleaning every once in a while, which not only increases the use and maintenance cost, but also reduces the service life of the finger type conveying chain. Content of the Utility Model

[0007] Preferably, the mounting plate is connected to the brush plate through a clamping structure; the clamping structure includes L-shaped guide plates symmetrically and fixedly connected to both sides of the mounting plate, a stop block fixedly connected to the short side at one lower end of the mounting plate, and a limiting block clamped at the short side at the other lower end of the mounting plate; a dovetail groove for inserting the limiting block is provided on the mounting plate, and the upper part of the limiting block is shaped to be adapted to the dovetail groove and frictionally engaged with the dovetail groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the specific embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As shown in the Figures 1-4As shown in the figure, a windrower includes a frame 1, a dividing device 2, a cutter assembly 3, a front conveying baffle 4, and a finger-type conveying chain 5 mounted on the frame 1. On the frame 1, above the finger-type conveying chain 5, a rotating shaft 7 is rotatably mounted through a mounting seat 6. A swing arm 8 is fixedly connected to the rotating shaft 7. A mounting plate 9 is fixedly connected to the lower end of the swing arm 8. A brush plate 10 is fixedly connected to the lower end surface of the mounting plate 9. The bristled surface of the brush plate 10 is in contact with the upper end of the finger-type conveying chain 5.

[0022] As a preferred technical solution of this embodiment, the mounting plate 9 is connected to the brush plate 10 through a clamping structure. The clamping structure includes guide plates 11 symmetrically fixedly connected to both sides of the mounting plate 9 and in an L shape, a stop block 12 fixedly connected to the short side at one end of the lower end of the mounting plate 9, and a limiting block 13 clamped to the short side at the other end of the lower end of the mounting plate 9. A dovetail groove 14 for inserting the limiting block 13 is provided on the mounting plate 9. The upper part of the limiting block 13 is adapted to the dovetail groove 14 and is frictionally engaged with the dovetail groove 14.

[0023] When the brush plate 10 is installed, its plate body is inserted along the guide plates 11 and enters between the guide plates 11 to achieve positioning on the long side. And the protruding part at the lower end of the guide plates 11 cooperates with the mounting plate 10 to clamp the edge of the plate body of the brush plate 10 to achieve vertical limitation. The two ends are limited and fixed by the stop block 12 and the limiting block 13. The limiting block 13 is preferably made of a rubber block, which can be frictionally engaged with the dovetail groove 14 to facilitate its disassembly and assembly to meet the replacement of the brush plate 10.

[0024] As an alternative to the connection method between the mounting plate 9 and the brush plate 10, as Figure 5 shown, a connection hole 15 is provided on the mounting plate 9. The brush plate 10 is connected to the mounting plate 9 through a bolt (not shown in the figure). The brush plate 10 is replaced by disassembling and assembling the bolt. Correspondingly, a mounting hole (not shown in the figure) corresponding to the connection hole 15 is provided on the plate body of the brush plate 10. Obviously, the mounting plate 9 and the brush plate 10 can also be connected by a magnetic attraction method. For example, a strong porcelain piece is fixedly connected to the lower end of the mounting plate 9, and an iron sheet is fixed to the upper end of the plate body of the brush plate 10.

[0025] As a variation of the technical solution of this embodiment, the rotating shaft 7 is fixedly connected to the mounting seat 6. At this time, the position between the brush plate 10 and the finger-type conveying chain 5 is fixed, and the brush plate 10 cannot be rotationally adjusted according to wear.

[0026] When the rotating shaft 7 and the mounting seat 6 are rotatably connected, after the bristled surface of the brush plate 10 is worn, the rotating shaft 7 can rotate by itself to ensure that the bristled surface of the brush plate 10 maintains effective contact with the chain of the finger-type conveying chain 5, ensuring a better cleaning effect. When the brush plate 10 needs to be replaced, or when the finger-type conveying chain 5 needs to be maintained, only the rotating shaft 7 needs to be rotated to turn the mounting plate 9 and the brush plate 10 upwards.

[0027] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
