Description

Conveyor chain capable of preventing stones from being clamped

Technical Field

The invention belongs to a conveying chain, and particularly relates to a conveying chain capable of preventing stones from being clamped.

Background

At present, the whole conveying chain of some root crop harvesters is driven by two or four chains, the distance between force transmission points of chain shafts is too large, and the chain shafts deform to influence the separation of crops and soil. The chain is sometimes filled by hard blocks such as stones, and the chain is easy to fall off, so that the work of the harvester is interrupted. Some enterprises do not need the chain to transmit in order to solve the problem that the chain shaft deforms and falls, but use a group of chain wheels to simultaneously drive the conveying chain shaft, and the chain plate is positioned by two gaskets welded on the chain shaft. The machine type effectively improves the stress condition of the chain shaft, but the chain shaft cannot be taken out of the chain plate without damage, and the maintenance is difficult. Some models adopt a structure that a rubber chain wheel, a chain and rubber are bonded on a chain shaft, and the problem that the chain shaft deforms to influence crop cleaning is also solved. In the aspect of trafficability, when the number of plant stems and leaves or weeds is large, a serious congestion phenomenon exists. When the digging depth exceeds sixty centimeters, harvesting work cannot be performed.
