Agricultural grain dust raising and removing device

Abstract

The invention discloses an agricultural grain dust raising and removing device. A material storing box is arranged at the upper part of a device body; a driving motor is arranged at the upper end of the material storing box; the right side of the driving motor is rotationally connected with a driving shaft; the middle part of the driving shaft is fixedly connected with a first bevel gear; the first bevel gear is engaged with a second bevel gear; the second bevel gear is fixedly connected with a driven shaft; a bearing of the driven shaft is rotationally connected with the material storing box;a material guide pipe communicates with the bottom of the right side of the material storing box; the lower end of the material guide pipe is bonded with the upper surface of a movable baffle; a through hole is formed in the left side of the movable baffle; the right side of the movable baffle is connected with a sleeve plate in sleeved manner; the right side of the sleeve plate is fixedly connected with the device body; and a reset spring is arranged in the sleeve plate. With the adoption of the agricultural grain dust raising and removing device, the driving shaft drives the driven shaft tofollow to rotate, under the combined action of the reset spring and a first eccentric wheel, the movable baffle is driven to move leftwards and rightwards in a reciprocating manner, at the same timea transmission belt drives a rotating shaft to follow to rotate, grains are leaked from a leaking hole in the left side of a cross plate, and second eccentric wheels which rotate drive the cross plateto vibrate up and down in a reciprocating manner, so that the grains on the right side of the cross plate are raised and dust is removed.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an agricultural grain dust removal device. Background technique [0002] In ancient Chinese books, a machine that can generate wind (or airflow) is called a fan car, fan car, lift car or "windmill". In order to avoid confusion with windmills, which are machines that use wind power, people refer to machines that generate wind as fan cars. The grain lifter is a fan machine used to remove rice and wheat husks, also known as wind cabinet, fan machine, shovel, lifter, fan, and grain lifter. It was an extremely necessary tool for the agricultural revolution in the West. In the 2nd century BC, the working people in ancient China invented the rotary grain raising fan cart. It was not until the beginning of the 18th century that the West had Yanggu fan carts, about 2,000 years later than China.

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing grain lifting devices cannot realize the automatic feeding function, and need manual assistance to complete the operation. The degree of automation is not high, and the existing samples do not have the function of secondary grain lifting, and the dust cleaning is not thorough enough.
