Problems solved by technology

[0002] At present, the crawler self-propelled harvesting machine with the patent publication number CN2534799 includes a spike-tooth type threshing drum, which mainly relies on a spike for threshing. Big
Publication No. CN02288324.X and Publication No. CN201821666 double-screw-toothed threshing drum, this structure has a high removal rate and less entrainment loss, but the impact is strong, the damage to the grain is large, the stem is severely broken, and the prolapse is moderately broken. The large amount of stalks and debris increases the cleaning load, which increases the cleaning loss rate and reduces the cleaning rate
The patent number is CN20061003824.6 bar-type threshing drum, which has good threshing rubability, but it is heavy when applied to the crawler self-propelled full-feeding combine harvester

Abstract

The invention discloses a track self-running type cutting longitudinal flow full-feeding combine harvester. A threshing rotary drum assembly comprises an arch tooth cutting flow threshing barrel and a nail tooth longitudinal axial flow threshing rotary drum; the arch tooth cutting flow threshing barrel is radially arranged at the front part of a stander (3); and the nail tooth longitudinal axial flow threshing rotary drum is axially arranged at the rear part of the stander (3). The track self-running type cutting longitudinal flow full-feeding combine harvester is high in threshing performance, small in entrainment amount and low in seed breakage rate; and furthermore, the track self-running type cutting longitudinal flow full-feeding combine harvester can smoothly and efficiently run in long-straw and high-yield difficultly threshed grain fields without being blocked.

Description

technical field [0001] The invention relates to a crawler self-propelled cutting vertical flow full-feed combine harvester. Background technique [0002] At present, the crawler self-propelled harvesting machine with the patent publication number CN2534799 includes a spike-tooth type threshing drum, which mainly relies on a spike for threshing. big. Publication No. CN02288324.X and Publication No. CN201821666 double-screw-toothed threshing drum, this structure has a high removal rate and less entrainment loss, but the impact is strong, the damage to the grain is large, the stem is severely broken, and the prolapse is moderately broken. The large amount of stalks and debris increases the cleaning load, which increases the cleaning loss rate and reduces the cleaning rate. The patent No. is CN20061003824.6 grain rod type threshing cylinder, and its threshing rubbing property is good, but weight is heavier when being used on crawler belt self-propelled type full-feed combine h...
