Abstract

The invention relates to a compound cleaning and sorting screen of a whole-feed harvester. The compound cleaning and sorting screen comprises vibrating screens and a shutter screen, and is characterized in that the vibrating screens comprise a first vibrating screen and a second vibrating screen which are arranged on two layers, wherein the first vibrating screen, the second vibrating screen and the shutter screen are in step distribution from top to bottom; each vibrating screen comprises a shaking board and a shaking steel wire which is connected with the shaking board, the shaking steel wire of the first vibrating board completely coincides with the shaking board of the second vibrating screen in the direction from top to bottom, and the shaking steel wire of the second vibrating screencompletely coincides with the shutter screen in the direction from top to bottom. According to the provided compound cleaning and storing screen of the whole-feed harvester, comprehensive graded screening for crops can be performed, repeated screening can be performed when many impurities are contained in the crops and one-time screening is performed when few impurities are contained, particularly, clumps falling in the position close to the input end of a threshing cylinder are repeatedly screened, the cleaning and sorting area is large, and the cleaning and sorting capacity is strong.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a compound cleaning screen for a full-feed harvester. Background technique [0002] The full-feed combine harvester feeds all the crop stems and ears into the threshing device for threshing. It is widely used in the Chinese market, especially the cleaning screen in the thresher plays a vital role in the thresher. People have designed a lot of patents for this reason, and for example the Chinese patent that publication number is CN201220734243 discloses a kind of vibrating screen cloth with conveying rack, comprises screen cloth, and described screen cloth comprises horizontal bar and longitudinal bar, and a plurality of described horizontal bars Rods and vertical rods are criss-crossed to form the mesh of the screen, the horizontal bar is a rack, and a plurality of through holes are arranged under the teeth of the rack, and a plurality of the racks are arranged vertically to form the ho...
