Quick replacement device for multi-crop header and crawler-type intelligent combine harvester

Abstract

The invention discloses a quick replacement device of a multi-crop header and a crawler-type intelligent combine harvester. The quick replacement device of the multi-crop header comprises a quick hooking part and a power transmission part. The quick hooking part comprises a fixing device, a guide column, a locking plate and a locking hydraulic cylinder. The power transmission part comprises an input belt pulley, middle belt pulleys, a middle gear, a power input gear and a belt tensioning wheel. According to the quick replacement device of the multi-crop header, the requirement of quick replacement of different crop headers can be met, and quick hooking and locking can be realized. The quick replacement device is simple in structure and convenient to operate, replacement of the header can be completed by only one person, and quick hooking and locking can be achieved; and meanwhile, the rotating speed and power input into the header part can be changed by replacing the middle belt pulleys of different models, and the operation requirements of different headers are met.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a quick replacement device for a multi-crop header and a crawler-type combine harvester. Background technique [0002] The combine harvester is a harvesting machine that can complete the harvesting, threshing, separating stems, removing debris and other processes of cereal crops at one time, and directly obtains grains from the field. The types of domestic combine harvesters are still mainly special-purpose ones. One combine harvester can only harvest one or two types of crops at most, resulting in insufficient machines during busy farming seasons and idle machines at other times. The multi-crop rotation system in our country will inevitably require a As a multi-purpose general-purpose combine harvester, the header frame is an important part of the header exchange of the multi-crop combine harvester. It is of great significance to reduce the labor inten...

Problems solved by technology

Realized the quick coupling of the header, but did not solve the impact of the power transmission mode on the replacement efficiency

Chinese patent CN205026261U specifically relates to a general-purpose combine harvester independent header modular hydraulic interface, which transmits the power of the harvester to the header part through hydraulic transmission. Combine harvester, it is difficult to be applied on ordinary combine harvester
