Harvester header device with multiple obliquely-arranged disc-shaped cutters and harvesting method

Abstract

The invention discloses a harvester header device with multiple obliquely-arranged disc-shaped cutters and a harvesting method. The harvester header device comprises a header rack, the disc-shaped cutters, a transmission device and a conveying device. The header rack is installed on a harvester chassis, the disc-shaped cutters are installed on the header rack and driven by a power device on the harvester chassis through the transmission mechanism, the two or more disc-shaped cutters are combined into a disc-shaped cutter combination, all disc-shaped cutter devices of the disc-shaped cutter combination are transversely and obliquely arranged relative to a harvester, a conveying chain with shifting teeth is arranged on the cutters of the disc-shaped cutter combination, the front transverse conveying part of the conveying chain and the side backward conveying part of the conveying chain are combined into the whole chain, and the front transverse conveying part is arranged with the same oblique angle as the disc-shaped cutters. According to harvester header device with the multiple obliquely-arranged disc-shaped cutters, the multiple disc-shaped cutters are adopted, whole oblique conveying is achieved, intermediate connection between the two subsection conveying chains can be reduced, and conveying is smoother.

Description

technical field [0001] The invention belongs to an agricultural operation device, in particular to a header device of an agricultural crop stalk harvester, which is mainly used for thick stalks, high stalks, high cutting resistance, and need to harvest the whole stalk and carry out post-laying or side-laying The utility model relates to harvesting of stalk crops; it belongs to the technical field of agricultural operation machinery. Background technique [0002] At present, the mechanized harvesting of major agricultural crops such as rice and wheat uses reciprocating triangular cutters, which are arranged horizontally. Agronomy requires harvesting of the seeds. There is no requirement for the stubble height and laying of the stalks, only the upper part needs to be cut. For the part with grains, the stalks are soft, small, low and easy to cut, and can be easily grasped and fed by the reel. After threshing, separation and cleaning, the stalks can be thrown to the rear. , the...

AI Technical Summary

Problems solved by technology

The cutting knives of the above-mentioned harvesters are all arranged horizontally. In order to realize side laying or rear laying, a horizontal conveying belt or chain with shifting teeth is set above the cutting knives, and a backward conveying belt is also set for rear laying. The longitudinal conveying belt or chain, due to the horizontal conveying to the longitudinal conveying forms a 90° turn, where the horizontal velocity of the stalk suddenly drops to zero, while the longitudinal velocity suddenly increases from zero, resulting in jamming, while the front horizontal conveying dial The teeth cannot form a grip on the stalk, and it is easy to cause the incoming stalk to fall out and fall forward, forming a jam in the front, so that the harvest cannot be carried out smoothly
