Abstract

The invention relates to a lower cutting knife driving device. The lower cutting knife driving device comprises a crank; one end of the crank is connected with a power device, and the other end of thecrank is connected with a steering pull rod; the steering pull rod is connected with a rocker arm assembly; the other end of the rocker arm assembly is arranged in a horizontal sliding groove of a lower cutting knife device in a sleeved manner. Longitudinal reciprocating driving of the crank and the steering pull rod is converted into horizontal reciprocating driving of the lower cutting knife device to achieve the goal of cutting, and a lower cutting knife of a harvester works. The lower cutting knife driving device has the advantages that a driving chain is simple, parts are few, processingis simple, manufacturing cost is low, universality is high, the requirement on an installation technique is not high, driving is reliable and maintenance is convenient, and can be applied to all types of small and medium-sized combine harvesters.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a lower cutter transmission device of a small and medium-sized combine harvester. Background technique [0002] Existing small and medium-sized combine harvesters have generally adopted the lower cutting knife technology, and its transmission structures are various, such as belt cross type and gear box type structures, but the above transmission methods have the disadvantages of complex design, high manufacturing cost and poor versatility. shortcoming. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a lower cutter transmission device of a small and medium-sized combine harvester which has the advantages of flexible operation, stable and reliable transmission, simple manufacture and strong versatility. [0004] The technical solution adopted by the present invention to solve t...
