Abstract

The invention provides a grain separating system for a longitudinal axial flow type harvester. The grain separating system comprises a rack, wherein the upper part of the rack is provided with a threshing drum and a rethreshing device; the lower part of the threshing drum is provided with a vibrating sieve; the left side of the vibrating device is provided with a separating fan, and the lower part of the vibrating sieve is provided with a foreign-residual matter horizontal conveying auger and a grain-discharging horizontal auger; the foreign-residual matter horizontal conveying auger is connected with a vertical foreign-residual matter transferring auger which is arranged at the back part of the rack; the foreign-residual matter transferring auger is connected with the rethreshing device. The grain separating system provided by the invention has the advantages that due to the adoption of a special design structure with combination of the vibrating sieve, the fan and the threshing drum, multi-time separation can be carried out in a circulating manner, the separation is more complete and the separation efficiency is high.

Description

technical field [0001] The invention belongs to harvesters, in particular to a grain cleaning system for vertical axial flow harvesters. Background technique [0002] The longitudinal axial flow harvester adopts the detachment method of longitudinal axial flow. The grain is fed into the auger by the header and then conveyed through the bridge. It is fed by blades, and the axial flow drum is inclined vertically. The axial flow drum is inclined relative to the machine body, which greatly increases The separation time is shortened, and the loss rate is effectively reduced. The grain cleaning system of ordinary vertical axial flow harvesters can generally only be cleaned once, and the cleaning is not complete enough, and the cleaning effect is not good enough. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a grain cleaning system for longitudinal axial flow harvesters. [0004] A grain cleaning system for a v...
