Header crop clamping height adjustment device for half-feed harvester

Abstract

The invention relates to a crop clamping height adjusting device of a header of a semi-feeding type harvester. The crop clamping height adjusting device comprises a rack, a lower-layer transmission conveying assembly, a middle-layer transmission conveying assembly and an upper-layer transmission conveying assembly, wherein the lower-layer transmission conveying assembly, the middle-layer transmission conveying assembly and the upper-layer transmission conveying assembly are arranged on the rack. The rack is installed between a crop collecting and conveying device of the header and a clamping chain mechanism which enables crops to be horizontally arranged and conveyed for threshing. The bottom of the rear end of the rack is provided with a cantilever rod which is fixed to the rack. The cantilever rod is movably arranged in a cantilever pipe of a harvester body to enable the whole rack to be capable of rotating around the cantilever pipe. The bottom of the front end of the rack is provided with an adjusting lever which can be used for vertically adjusting the inclination angle of the rack. According to the crop clamping height adjusting device, the rack is installed between the crop collecting and conveying device of the header of the semi-feeding type harvester and the clamping chain mechanism which enables the crops to be horizontally arranged and conveyed for threshing, the transmission structure is ingenious, a vertical-to-horizontal transition side baffle plate is omitted, the size of the transmission structure greatly shrinks, and the crop clamping height adjusting device is low in manufacturing cost, high in working reliability and applicable to miniaturization development.

Description

technical field [0001] The invention relates to a crop clamping height adjustment component of a harvester, in particular to a header clamping height adjustment device of a half-feed harvester. Background technique [0002] The existing semi-feeding rice and wheat combine harvesters, such as Japan's Kubota, Yanmar, South Korea's Dongyang and domestic manufacturers, have relatively complicated threshing stalk crop conveying mechanisms, and generally adopt relay conveying, that is, the stalk crops are transported from The stalks are collected by the header, and the stalk crops sent from the collection and conveying device of the header are upright, and are transformed into a horizontal arrangement through a clamping chain mechanism and transported to the threshing drum for threshing, and the threshed straw is then converted by the relay mechanism until the grass discharge chain device is discharged out of the machine. In order to enable the semi-feeding harvester to achieve t...

Problems solved by technology

However, before entering the crop clamping adjustment device, there will also be a turning side baffle that turns vertically and horizontally; the ears of the stalk crops will violently hit the turning side baffle to produce threshing by turning in this way, which will bring losses to production. To overcome this phenomenon, the existing technology is usually to increase the radius of curvature of the turning side baffle. These measures make the transmission structure bulky, restrict the miniaturization of the half-feed combine harvester, and become one of the obstacles to the development of small half-feed combine harvesters. one
