Abstract

The invention discloses a longitudinal axial flow threshing device of a whole-feed combine harvester. A charging chamber connected with a threshing chamber into a whole is added between the upper end of a middle conveying trough and the front end of a longitudinal threshing cylinder; the feeding chamber is internally provided with a transverse charging cylinder; the upper end of the middle conveying trough is connected with the inlet of the charging chamber; the bottom surface of the outlet of the charging chamber is connected with a concave sieve plate by a transition plate; the output end of a secondary re-threshing transporter is connected to the front part of the left side of the threshing chamber and is connected above the transition plate. Because of adding the charging cylinder, the improved threshing device of the invention greatly strengthens feed speed and throwing strength to the threshing cylinder charging so as to effectively avoid the detect that the longitudinal axial flow threshing chamber of the whole-feed combine harvester has large possibility of blocking; meanwhile, the output end of the secondary re-threshing transporter is connected above the charging transition plate of the threshing cylinder connected with the front end of the concave sieve plate instead of being above the traditional sorting screen, thus greatly lightening the material processing strength of the sorting screen, and reducing material sorting loss.

Description

technical field

[0001] The invention relates to a threshing device of a full-feed combine harvester. Background technique

[0002] The threshing device of the existing full-feed combine harvester generally has a threshing chamber in its structure. The threshing drum, concave plate sieve, and cleaning sieve are installed in the threshing chamber from top to bottom. The threshing chamber space at the bottom of the cleaning sieve is the cleaning chamber. , the front end of the cleaning room is equipped with a fan, and the space of the cleaning room is composed of V-shaped plates respectively. A secondary horizontal conveying auger is installed under the silo, and the outlet end of the secondary horizontal conveying auger is connected with a secondary re-removal drum, and the radial side of the secondary re-removal drum is connected with a secondary lifting conveying auger. The secondary horizontal conveying auger, the secondary re-extracting drum and the secondary lifting conv...

Embodiment Construction

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] A threshing chamber 11 is installed on the chassis 16 of the full-feed combine harvester, and an intermediate delivery trough 2 is connected between the front end of the threshing drum of the threshing chamber 11 and the header 1 of the harvester. Inside the threshing chamber 11, a vertical threshing drum 7 whose axis is parallel to the advance direction of the harvester, a concave plate sieve 8, and a cleaning sieve 10 are installed from top to bottom. Inner front, fan 15 is installed at the bottom of cleaning sieve 10, and the threshing chamber space at the bottom of cleaning sieve 10 is formed by V-shaped plate respectively before main feed bin 13 and rear secondary feed bin 12. The full concentrate in the front main silo 13 is conveyed to the grain bin of the harvester through the conveying auger 14; Composed of a small re-extraction drum and a secondary lift...
