Problems solved by technology
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

The double shaker plate diverter mechanism for corn grain cleaning materials belongs to agricultural machinery; The upper jitter plate mechanism composed of jitter plates and the driven drive shaft bracket, driven drive shaft, driven crank pulley, crank B, connecting rod B, lower jitter plate, hinge seat B, diversion base plate support, diversion The lower jitter plate mechanism is composed of the diverter bottom plate, Π-shaped diversion front and rear baffles, and evenly distributed diverter plate group. A hole-shaped sieve plate is set on the upper jitter plate, and the transmission belt is set on the driving crank pulley and the driven crank pulley. The upper and lower jitter plates and the diversion and diversion bottom plates are located below the upper jitter plate and the perforated sieve plate; this mechanism makes full use of the operation functions of the upper and lower jitter plates, and has the advantages of reasonable structure, good effect of conveying and cleaning corn materials, and avoiding It has the characteristics of high material accumulation and high 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...
