Crawler-type self-propelled combine harvester

Abstract

A crawler-type self-propelled combine harvester is mainly composed of a threshing cleaning device, a horizontal screw conveyor, a vertical screw conveyor, a grain tank, a conveying trough, a console,a chassis, a header, a reel, a secondary cutting device and a traveling mechanism; the travelling mechanism has a front-driving crawler type structure and the driving wheels are gear tooth type; a cutter is a II-type casting cutter; the secondary cutting device is configured under the rear of the header; the vertical height of the upper cutter and the lower cutter on the header is adjustable; theradial blower fan cylinder screen cleaning device is mainly composed of a conveying trough, a concave screen, a radial blower fan, a front cylinder screen, a rear cylinder green, a centrifugation blower fan and a screw conveyer, which form a dual-screen and dual-blower fan structure; a secondary threshing device is composed of a group of miniature threshing rollers and concave screens. The invention has the advantages of simple structure, reasonable arrangement, high work efficiency, low production cost, stable operation and simple operation, and can well meet the wheat harvest requirements inthe northwest region.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a crawler self-propelled combine harvester. Background technique [0002] my country is a big wheat planting country, and its output accounts for 40% of the grain output. The segmented harvesting method is mainly used in North China, but the promotion and application of wheat combine harvesters is very fast, mainly because its geographical conditions are better than those in the Northwest. The natural conditions, crop varieties, farming habits, agronomic requirements, and economic conditions of agricultural production in Northwest my country are quite different from those in the north, because the fields in these places are small, the fields are less connected, and the gap between fields is large. , Narrow roads for mechanical farming, large and medium-sized combine harvesters are not suitable for these areas, etc. Wheat combine harvesters are used less, the level ...

Problems solved by technology

The natural conditions, crop varieties, farming habits, agronomic requirements, and economic conditions of agricultural production in Northwest my country are quite different from those in the north, because the fields in these places are small, the fields are less connected, and the gap between fields is large. , Narrow tractor roads, large and medium-sized combine harvesters are not suitable for these areas and other reasons, wheat combine harvesters are used less, the level of production mechanization is low, the harvesting method is mainly manual harvesting, and the entire harvesting process is completed manually, which is labor intensive and the whole The harvesting process takes a long time, is inefficient, labor-intensive, and causes serious loss and waste
