Rapeseed threshing, screening and drying apparatus

Abstract

The invention discloses a rapeseed threshing, screening and drying apparatus, comprising a support plate. A working box is arranged above the support plate; a plurality of support arms are fixedly connected to the sidewall of the working box; a mounted bearing is arranged at the top of the support plate and is rotationally connected with a rotary shaft; a crank is fixedly connected to the top endof the rotary shaft; the crank is rotationally connected with the bottom ends, far away from a support, of the support arms; a screen mesh is fixed in the working box; a top plate is fixed above the support plate through a support; an electric push bar is fixed to the top center of the top plate; the bottom end of the electric push bar is passed through the top plate and is fixedly connected witha press plate. The crank rotates to drive the working box in cyclic motion; the working box cooperates with squeezing of the press plate to roll and thresh rapeseed crops, the threshing effect is good, and threshing efficiency is high; the screen mesh screens the threaded rapeseed; the rapeseed shakes peripherally with the working box during screening so that the screening effect is good.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rapeseed threshing, screening and drying device. Background technique [0002] Rapeseed, also known as brassica seed, is a herbaceous cruciferous crop, one of the main oil crops and nectar crops in China, and its seeds are one of the main varieties of raw materials for making oil. Cultivated throughout China, it is divided into two types: winter rape and spring rape. Its planting area accounts for more than 40% of China's total oil crop area, and its output accounts for more than 30% of China's total oil crop output, ranking first in the world. [0003] When the rapeseed is harvested, the rapeseed must be taken out from the rapeseed so that it can be used for oil extraction; after the common agricultural households dry the rapeseed, they thresh the rapeseed by beating or squeezing, the threshing effect is not good, and it is a waste of energy; After threshing, ...

AI Technical Summary

Problems solved by technology

[0003] When the rapeseed is harvested, the rapeseed must be taken out from the rapeseed so that it can be used for oil extraction; after the common agricultural households dry the rapeseed, they thresh the rapeseed by beating or squeezing, the threshing effect is not good, and it is a waste of energy; After threshing, the rapeseed contains a lot of water, which is not conducive to storage. Generally, it needs to be dried in the sun. If it encounters cloudy and rainy weather, the water content of the rapeseed is high, and the air is humid, the rapeseed is easy to deteriorate, and it is not conducive to oil extraction.
