A retractable harvester header

Abstract

The invention relates to a telescopic header of a harvester. The rear part of a middle header 1 is connected with a bridge of the harvester, a screw feeder 9 is mounted at a feeding port of the header and the bridge at the middle part of the middle header 1, and horizontal conveying belts 10 are mounted at the two sides of the screw feeder 9 and are separately located below a left telescoping header and a right telescoping header; cutting knives 8 are mounted at the front part of the left telescoping header 2 and the front part of the right telescoping header 3, middle parts of the left and right cutting knives extend to the front part of the middle header 1, and high, low, front and rear positions are staggered; and a left conveying auger 11 and a right conveying auger 12 are separately mounted at the middle part of the left telescoping header 2 and the middle part of the right telescoping header 3, rear parts of the left and right telescoping headers are separately mounted in slideways at the left and right sides of the middle header 1, one end of a telescopic oil cylinder 6 is hinged to a framework of the middle header 1, and the other end of the telescopic oil cylinder 6 is hinged to frameworks of the left and right telescoping headers separately.

Description

technical field [0001] The invention relates to a harvester header, in particular to a retractable harvester header. Background technique [0002] At present, the cutting width of combine harvester headers in the society is mostly fixed. The headers of this structure are only suitable for small and medium-sized combine harvesters, and are not suitable for large combine harvesters, because if the cutting width of the header Widening, road transportation and transition walking are extremely inconvenient. If the cutting width of the header is narrowed, the feeding amount of the harvester is not enough. Contents of the invention [0003] The purpose of the present invention is to overcome the above deficiencies and provide a telescopic harvester header, which mainly consists of a middle header, a left telescopic header, a right telescopic header, a telescopic reel support, a telescopic reel, a telescopic oil cylinder, Composed of eccentric discs, etc., it is characterized in ...
