Harvester large drum rear plate screen

Abstract

The invention discloses a harvester large drum rear plate screen comprising a plate screen body (1), side plates (2), an anti-corrosion wear-resisting layer (3), a screen (4), a first reinforcing rib(5), a second reinforcing rib (6), a third reinforcing rib (7), a base plate (8) and an inserting plate (9); side plates (2) are installed at two sides of the plate screen body (1); the anti-corrosionwear-resisting layer (3) is installed on external surface of the side plates (2); the anti-corrosion wear-resisting layer (3) is applied with the side plates (2); the base plate (8) is installed at abottom of the plate screen body (1); the base plate (8) is welded to the plate screen body (1); the inserting plate (9) is installed at an upper end of the plate screen body (1); the inserting plate(9) is welded to the plate screen body (1); the screen (4) is installed on the plate screen body (1); the first reinforcing rib (5), the second reinforcing rib (6) and the third reinforcing rib (7) which are adapted to each other are installed in the screen (4). The harvester large drum rear plate screen of the invention has reasonable design and stable connection; the side plate has good anti-corrosion and wear-resisting performance.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a large drum rear plate screen for harvesters. Background technique [0002] Harvester It is an integrated machine for harvesting crops. Harvesting, threshing and concentrating the grains into the storage bin at one time, and then transporting the grains to the transport vehicle through the conveyor belt. Manual harvesting can also be used to spread the stalks of rice, wheat and other crops in the field, and then use grain harvesting machinery to pick up and threshing. Crop harvesting machinery for harvesting grains and stalks of cereal crops such as rice and wheat. Including harvesters, windrowers, balers, grain combines and grain threshers, etc. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools. The structure design of the rear plate screen of the existing large drum of the harvester is unreasonable, the connection...
