Hydraulically-driven rape combine harvester

Abstract

The invention discloses a hydraulically-driven rape combine harvester which comprises a tracked chassis traveling device, a header, a longitudinal-axial-flow threshing and separating device and a cyclone separation cleaning system. The header is arranged at the front end of the tracked chassis traveling device which comprises a chassis, a cab, a diesel engine and traveling gearbox, the diesel engine is positioned in rear of the cab which is positioned at the front end of the chassis, the traveling gearbox is positioned on one side of the cab, and the diesel engine supplies power to the traveling gearbox through belt transmission. The longitudinal-axial-flow threshing and separating device is connected with a discharging port in the rear end of the header and provided with a forced feeding device, and the cyclone separation cleaning system is arranged at the rear end of the tracked chassis traveling device. By adoption of the segmental header, the header is adjustable in height according to practical requirements to better adapt to environments of fertile farmland and slope planting in the middle and lower Yangtze regions; by means of full hydraulic driving, simplicity in operation is achieved; since a traditional chain harrow type conveyor is replaced by the longitudinal-axial-flow threshing and separating device with the forced feeding device, a stem flow route is shortened.

Description

technical field [0001] The invention belongs to the technical field of harvesting in agricultural machinery, and in particular relates to a hydraulically driven rapeseed combine harvester. Background technique [0002] Rapeseed is one of the most important oil crops in the world. It is currently the second largest edible vegetable oil and oil meal raw material in the world. It is widely used in feed, chemical, energy and other fields, and occupies a very important position in the global trade of oil products. my country is one of the main rapeseed producing areas in the world, but the production of rapeseed in my country is relatively backward, which is mainly reflected in the backwardness of production means, resulting in high production costs and low benefits, which is not conducive to improving the enthusiasm of farmers and restricting the development of rapeseed industry in my country. Seeds and rapeseed oil are generally net imports, and their international competitivene...

AI Technical Summary

Problems solved by technology

[0004] The structure of the traditional rapeseed combine harvester is complicated, and the chain rake conveyor is often used between the header and the threshing and separating device; the cleaning device mostly uses a fan and a reciprocating vibrating screen, and the vibration of the whole machine is large; most of the working parts use mechanical transmission, and the transmission is complicated
