Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as Figure 1-4 As shown, the harvester threshing drum includes a threshing drum body 1 and a drum box body, and the drum box body includes a side guard plate 2 , a middle partition plate 3 , an upper cover plate 4 and a drum box bottom plate 5 .

[0027] Wherein, the middle part of roller box bottom plate 5 is bent downwards, as Figure 4 As shown, the front and rear sides of the roller case bottom plate 5 form baffles respectively, and the tops of the front and rear side baffles of the roller case bottom plate 5 are open, and the upper cover plate 4 is arranged on the open top of the roller case bottom plate 5, and the top of the roller case bottom plate 5 The front side apron stretches towards the clamping conveyor chain 6 . The bottom of the roller box bottom plate 5 forms an arc groove 7 close to the front side baffl...

Abstract

The invention discloses a threshing cylinder of a harvester. A cylinder box comprises side protection plates, a middle partition plate, an upper cover plate and a cylinder box bottom plate. The middle of the cylinder box bottom plate is bent downward, baffles are formed on the front side and the rear side of the cylinder box bottom plate respectively, the upper cover plate is arranged on the open top end of the cylinder box bottom plate, and the front baffle of the cylinder box bottom plate stretches to a clamping conveying chain; an arc-shaped groove is formed in the position, close to the front baffle, of the bottom of the cylinder box bottom plate, and the arc-shaped groove is in the lowest position of the cylinder box bottom plate; the middle partition plate is fixed to one end face of the cylinder box bottom plate, the other end face of the cylinder box bottom plate is fixedly connected with the side protection plates, and the cylinder box bottom plate, the upper cover plate, the middle partition plate and the side protection plates form a threshing cylinder cavity. Grain is gathered in the arc-shaped groove and discharged out through an auger, the arc-shaped groove is located in the bottom of the front side of the cylinder box, then a swing arm for lifting a header can be arranged in the position, close to the rear side, below the cylinder box bottom plate, and the distance between a driving chassis of the harvester and the header can be shortened.

Description

technical field [0001] The invention relates to a harvester, in particular to a harvester threshing drum used on the harvester. Background technique [0002] At present, the harvester threshing drum includes a threshing drum body and a drum casing. The bottom plate of the drum box is in the shape of a semicircle, and the center of gravity of the threshing drum of the harvester is relatively rearward, so that the distance between the front header and the rear driving chassis increases, and the overall length of the harvester is longer, larger in size and heavier in weight. [0003] Existing half-feed combine harvesters all use bottom threshing. After straw is threshed, it is clamped and pulled out of the threshing drum by the grass discharge chain, and then discharged to the straw crushing mechanism for crushing and then discharged or discharged directly. As a top-mounted threshing method, the left and right ends and the rear of the threshing machine are generally equipped w...
