[0002] Rapeseed is the main oilseed crop in my country. Vigorously developing the rapeseed industry not only needs to expand the planting area and increase the total output of rapeseed, but the traditional threshing of rapeseed relies on manual or semi-mechanized operations, which has a long harvest period, dela

Embodiment Construction

[0026] see Figure 1-Figure 4 , The flexible tooth threshing system with adjustable threshing gap of the present invention includes a threshing drum 20 installed on the frame 2 via a drum shaft 10 and a concave screen 13 installed below the threshing drum 20 . The drum shaft 10 is installed on the frame 2 through the drum support bearing 3, and the concave screen 13 is provided with a plurality of through holes 18 for convenient separation of oil seeds. The outer side of the threshing drum 20 is covered with a drum casing 11 , and a threshing chamber 1 is formed in the drum casing 11 . The threshing drum 20 is located in the threshing chamber 1, and includes two gap adjustment end plates 5 fixed on the drum shaft 10, and a plurality of threshing tooth fixing rods 7 with flexible threshing nail teeth 6 are arranged between the two gap adjustment end plates 5 . The drum shaft 10 at the input end of the threshing drum is provided with a feeding auger 4 distributed in a spiral s...

Abstract

The invention discloses a flexible-tooth threshing system with an adjustable threshing gap. The flexible-tooth threshing system comprises a threshing roller arranged on a rack and a concave grid, wherein the threshing roller is arranged in a threshing chamber, and comprises two gap regulating end plates fixedly arranged on roller shafts; a plurality of threshing tooth fixing rods with flexible threshing spike teeth are arranged between the two gap regulating end plates; a feeding auger which is distributed in a spiral manner is arranged on the roller shaft at the input end of the threshing roller; a feeding hole is formed in a roller housing corresponding to the feeding auger; a plurality of grass discharging plates are distributed on the roller shaft at the output end of the threshing roller; a straw outlet is formed in the roller housing corresponding to the grass discharging plates. The flexible-tooth threshing system with the adjustable threshing gap disclosed by the invention is used, so that acting time of crop silique on the flexible threshing spike teeth is prolonged, instant impact force is lowered, and crushing rate of rapeseeds can be lowered; meanwhile, the gap between the threshing roller and the concave grid is adjustable, and therefore, the flexible-tooth threshing system can meet threshing requirements varies by physical characteristics of a to-be-threshed material, and improves adaptation to the threshing material.

Description

technical field [0001] The invention relates to a threshing system of a thresher, in particular to a flexible tooth threshing system with adjustable threshing gap. Background technique [0002] Rapeseed is the main oilseed crop in our country. Vigorously developing the rapeseed industry not only needs to expand the planting area and increase the total output of rapeseed, but the traditional threshing of rapeseed is done manually or semi-mechanized. The threshing teeth have a strong impact on rape pods, and the seeds are severely broken. At the same time, because the threshing gap remains unchanged, they cannot adapt to the threshing requirements of the material to be threshed due to changes in physical properties. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to develop a flexible tooth threshing system with high productivity, low damage, and high adaptability, which can make people free from heavy, low-lev...
