Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The invention is implemented in detail, the low-damage roller device for threshing and harvesting comprises a feeding screw 1, a roller 2, a threshing element 3 and a grass discharging plate 4, wherein the feeding screw 1 adopts a conical screw feeding head and consists of a conical head, a spiral blade and a reinforcing rib, the feeding screw 1 and the roller 2 are fixed through welding, the spiral blade is arranged on the surface of the conical head, the reinforcing rib is arranged between the conical head and the spiral blade, the roller 2 adopts a closed longitudinal axial flow threshing roller, a roller shaft is arranged on the central axis of the roller 2, a width disc is arranged at one end of the roller 2, the threshing element 3 is provided with a plurality of threshing elements and fixedly connected through a base buckle welded on the surface of the roller 2, a filter screen with large aperture is arranged in the grass discharging plate 4 and arranged at the tail part of the roller 2, and the shell of the grass discharging plate 4 is welded and fixed with the roller 2.

The surface of the spiral blade is provided with a fish scale structure groove, and the spiral blade is fixed on the conical head through welding.

The cross section of the reinforcing rib is triangular, and the reinforcing rib is arranged between the conical head and the helical blade and is fixed by welding.

The threshing element 3 is fixedly connected through a base buckle welded on the surface of the roller 2, and the connecting seat is welded on the surface of the roller 2 in a spiral arrangement mode.
