Threshing device of self-propelled flax threshing reverse-laying device

Abstract

The invention discloses a threshing mechanism of a self-propelled flax threshing spreading machine, including a rack, a pair of smooth rollers for pressing flax arranged up and down and a pair of threshing awl rollers arranged up and down, wherein, the smooth rollers for pressing flax are driven by a pair of hydraulic motors, the rotation of the threshing awl rollers at same speed and in different directions is realized by a universal joint through two output shafts of a gear box which is driven by another hydraulic motor, and a plurality of stirrups are alternately arranged on the threshing awl rollers along the axial direction. The spreading machine picks up the retted flax in the field, transports the flax to a turning belt behind the machine by a delivery mechanism and puts the flax in strips; during the transportation process, a pair of smooth rollers for pressing flax grind the flax peaches, a plurality of smooth stirrups alternately arranged on the threshing awl rollers carry out hackling and threshing to the flax peaches, and the flax threshing in the flax turning process is realized. The threshing mechanism has simple structure, steady work, high threshing efficiency and small damage to the straws, and reduces the cost of activity and the labor intensity.

Description

technical field [0001] The invention relates to a harvesting and threshing machine in the field of agricultural machinery, in particular to a flax threshing device. Background technique [0002] 3-5 days after the flax matures, the quality of the flax is better, so it needs to be harvested in time. But at this time, the maturity of flaxseed is not good, the moisture content is high, and it is easy to deteriorate. Generally, the flax strips are laid in the cool sun for 3-8 days, and the flax seeds are harvested after the flax seeds are mature, so as to ensure the quality of flax and improve the quality of flax seeds. Like this just need a kind of flax machine that has turning over function and threshing function simultaneously. [0003] Existing flax threshing machinery mainly contains two kinds of threshing methods: one is the form of rubber roller or smooth roller rolling, as the patent No. is: 03284585.5, the flax threshing machine whose publication number is CN2643633Y,...

AI Technical Summary

Problems solved by technology

The two patents solve the manual conveying of flax and improve work efficiency, but there are still problems such as single threshing process, poor threshing effect, low cleaning rate and serious waste of grain

The other is drum threshing. Although it improves the cleaning rate and threshing effect, it does a lot of damage to the flax and affects the quality of flax fibers. In addition, the cost of the threshing drum is high and the structure is complicated. Processing high cost
