Abstract

The invention provides a wave sieve type grain cleaning mechanism, and belongs to agricultural machines. A driving shaft, a bent axle and a length adjustable type sliding rod assembly are mounted on aframe assembly, a driving pulley and two driving bevel gears are sequentially and fixedly mounted on the driving shaft, a driven bevel gear and a sleeve-mounted connection rod are fixedly mounted onthe bent axle, the driving bevel gears are engaged with the driven bevel gear, and a wave sieve type screen piece integrated body is configured above the frame assembly integrally, wherein the wave sieve type screen piece integrated body is formed through sequential hinging and series connection of N screen piece bodies through a plurality of pin-shaft combinations. The upper end and the lower endof the length adjustable type sliding rod assembly are connected with the pin-shaft combinations and a connection rod hinge. The wave sieve type grain cleaning mechanism adopts the wave sieve type screen piece integrated body to conduct wave-like type translation movement on grains, the effect that the grains are well separated from impurities is achieved, and the wave sieve type grain cleaning mechanism has the characteristics that the structure is novel and reasonable, the impurity cleaning working efficiency is high, the quality is good, and using is reliable.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a grain cleaning mechanism. Background technique [0002] Due to the deficiencies and defects in structural design, most of the cleaning sieves used in the current grain cleaning mechanism are rigid integral, and the driving mechanism can only realize the rigid movement of the rigid integral sieve. With the cooperation of the fan, In the operation of removing impurities from grain, due to the smooth surface of the sieve body, it is difficult to form a vortex of sufficient strength and quantity, resulting in unsatisfactory separation of grain and impurities, low operating efficiency, and poor cleaning effect and quality. Contents of the invention [0003] The purpose of the present invention is to develop a wave sieve type grain cleaning mechanism for the above-mentioned problems in the prior art, so as to achieve the purpose of improving the efficiency, quality and effect of grain...
