Multifunctional threshing device of combine harvester

Abstract

The invention discloses a multifunctional threshing device of combine harvester, comprising a threshing roller shelf, wherein, the threshing roller shelf is provided with a threshing roller and a top cover of the threshing roller; and a concave grid is arranged at the bottom of the threshing roller; a radialis disc is arranged axially on the threshing roller, rectangular toothed bars are evenly arranged on the circumference of the radialis disc by a fixing plate; threshing components are arranged on the rectangular toothed bars, threshing components are fixedly connected onto the rectangular toothed bars by a fixing device; the fixing device comprises long slots arranged on the rectangular toothed bars along the extending directions of the rectangular toothed bars; the fixing device also comprises a bolt I and a screw nut I, wherein, the bolt I passes through the long slot and then is connected with the threshing components, and the screw nut I is screwed into the bolt I and the threshing components are fixedly connected onto the rectangular toothed bars. The invention has the advantages of low threshing loss rate, low broken rate, and good threshing effect, meanwhile, users can arbitrarily combine the types and numbers of the threshing components according to actual situations, thereby the threshing is cleaner, and the power consumption is smaller.

Description

technical field [0001] The invention relates to a combine harvester, in particular to a threshing device of the combine harvester. Background technique [0002] Combine harvesters can be used to harvest rice, wheat, rapeseed, soybeans, etc. When harvesting rape, soybean, etc., due to the maturity and variety of rape and soybean, some pods of rape and soybean need to be rubbed to be threshed, while mature pods can be threshed only by gentle blowing. The threshing elements of the existing combine harvesters are usually welded on the web, and the threshing elements cannot be replaced. As a result, the threshing elements hit the rape and soybeans too hard during the harvesting of rapeseed and soybeans, so that the seed breakage rate is too high and the crops Poor seed cleanliness. The State Intellectual Property Office of China announced a name and a kind of threshing drum on May 15, 2008, and the announcement number is CN201222888. According to the specific implementation pa...
