Problems solved by technology

[0002] At present, it is common to use chains on harvesters, especially on large combine harvesters, but the chains on harvesters are often entangled by weeds or straw, especially on the sprocket teeth of the drive chain. There will be entanglement, which will lead to slipping teeth in severe cases, affecting the transmission and driving effect of the chain, and it is very troublesome to manually clean up the entanglement

Embodiment 1

[0043] Such as figure 1 and 2 As shown, a conveyor chain for a harvester provided by the present invention is formed by linking each chain link in sequence; each chain link includes two main chain plates 1, two secondary chain plates 2, two sleeves 3, two rollers Sub 4, two pin shafts 8 and an anti-winding mechanism;

[0044] The two main chain plates 1 are arranged in parallel and facing each other;

[0045] The two sleeves 3 are arranged in parallel between the two main chain plates 1, and a ring of limiting collar is provided on the outer circumference of the sleeve 3;

[0046] The two rollers 4 are sleeved on the two sleeves 3 respectively, and a limit groove is provided on the inner circumference of the rollers 4;

[0047] The said limiting protruding ring is embedded in the limiting groove, and can be rotated relatively, and the position of the roller 4 is relatively fixed by using the cooperation of the limiting protruding ring and the limiting groove, which will not...

Abstract

The invention discloses a conveying chain for a harvester. The conveying chain is formed by sequentially connecting all chain links. Each chain link comprises two main chain plates, two auxiliary chain plates, two sleeves, two rollers, two pin shafts and an anti-twisting mechanism. According to the conveying chain, by the adoption of the anti-twisting mechanism, a driving lever can be stretched out when the chain is operated to a chain wheel rotating position, so that a chain wheel is cleaned, the chain wheel is effectively prevented from being twisted, halt for manual cleaning is not needed, the harvesting efficiency of the harvester is effectively improved, and the conveying chain has an obvious technical effect.

Description

technical field [0001] The invention relates to a conveying chain, in particular to a conveying chain used on a combine harvester. Background technique [0002] At present, it is common to use chains on harvesters, especially on large combine harvesters, but the chains on harvesters are often entangled by weeds or straw, especially on the sprocket teeth of the drive chain. There will be entanglement, which will lead to slipping teeth in severe cases, affecting the transmission and driving effect of the chain, and it is very troublesome to manually clean up the entanglement. Contents of the invention [0003] Purpose of the invention: To provide a conveyor chain for a combine harvester that prevents entanglement at the sprockets. [0004] Technical solution: A conveying chain for a harvester according to the present invention is composed of chain links connected in sequence; each chain link includes two main chain plates, two secondary chain plates, two sleeves, and two ro...
