Cleaned corn kernel double-shaking-plate dividing mechanism

Abstract

The invention discloses a cleaned corn kernel double-shaking-plate dividing mechanism and belongs to the technical field of agricultural machinery. The corn kernel cleaned material double-shaking-plate dividing mechanism comprises an upper shaking plate mechanism and a lower shaking plate mechanism, wherein the upper shaking plate mechanism is composed of a main transmission shaft bracket, a driving transmission shaft, a driving crank belt pulley, a crank A, a connecting rod A, an upper shaking plate bracket, a hinge joint seat A and an upper shaking plate; the lower shaking plate mechanism iscomposed of a driven transmission shaft bracket, a driven transmission shaft, a driven crank belt pulley, a crank B, a connecting rod B, a lower shaking plate, a hinge joint seat B, a guiding and dividing bottom plate bracket, a guiding and dividing bottom plate, a Pi-shaped guiding front baffle plate, a Pi-shaped guiding back baffle plate, and uniformly distributed dividing plate groups; a holeshaped sieve plate is arranged on the upper shaking plate; a driving belt is mounted on the driving crank belt pulley and the driven crank belt pulley in a sleeving manner; and the lower shaking plateand the guiding and dividing bottom plate are positioned below the upper shaking plate and the hole shaped sieve plate. The cleaned corn kernel double-shaking-plate dividing mechanism fully utilizesthe operation function of the upper and lower shaking plates and has the characteristics of being reasonable in structure, excellent in cleaned corn material conveying effect to prevent material accumulation and high in cleaning efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a corn grain cleaning operation device. Background technique [0002] The cleaning device is the key device of the corn combine harvester, which affects the operating performance and harvesting efficiency of the harvester. As the important components of the cleaning device, the shaking plate and the vibrating screen play a decisive role in the cleaning performance. At present, most cleaning devices include two shaking plates and vibrating screens, which are divided into upper shaking plate, lower shaking plate, upper sieve and lower sieve. When working, materials are mostly concentrated on the upper shaking plate and upper sieve. If the working pressure of the upper shaking plate and the upper sieve is reduced, it is very easy to cause material accumulation on the upper sieve surface, which is not conducive to the penetration of the grain, affects the cleaning effect, and even caus...

At present, most cleaning devices include two shaking plates and vibrating screens, which are divided into upper shaking plate, lower shaking plate, upper sieve and lower sieve. When working, materials are mostly concentrated on the upper shaking plate and upper sieve. If the working pressure of the upper shaking plate and the upper sieve is reduced, it is very easy to cause material accumulation on the upper sieve surface, which is not conducive to the penetration of the grain, affects the cleaning effect, and even causes equipment failure. Perform secondary screening, which greatly wastes the utilization efficiency of the sieve
