Pressure sensor automatic regulation shaking board grain pull-over device

Abstract

The invention provides a pressure sensor automatic regulation shaking board grain pull-over device, and belongs to agricultural product processing machinery. A seat plate of a device frame is providedwith a supporting seat A, a supporting seat B, a front support rod, a rear support rod, an electric control cabinet and a servo motor separately, the supporting seat A and the supporting seat B are rotationally provided with a power transmission shaft A with a crank belt pulley A and a power transmission shaft B with a crank belt pulley B, a transmission belt A and a transmission belt B connect adouble-linked belt pulley on the servo motor with the crank belt pulley A and the crank belt pulley B, the front support rod is hinged with a long-hole type slide way plate, the two ends of a shakingconnecting rod are hinged with the crank belt pulley A and the long-hole type slide way plate respectively, a shaking board assembly with a pressure sensor is hinged, supported and arranged on the long-hole type slide way plate and on the rear support rod, the lower portion of the rear end of the shaking board assembly is hinged with a grid bar type pull-over plate, and the two ends of a push-pull connecting rod are hinged with the crank belt pulley B and the grid bar type pull-over plate respectively. The device has the advantages of good cleaning operation quality, high operation efficiencyand automation degree and few operation faults.

Description

technical field [0001] The invention belongs to agricultural product processing machinery, and mainly relates to an operating device on a corn grain cleaning machine tool. Background technique [0002] As of 2017, corn has become the crop with the largest planting area in my country. With the increase of corn planting area and corn yield, the performance requirements of corn mechanized harvesting operations are also getting higher and higher. Grain cleaning is one of the important links in the mechanized corn harvesting process, and the performance of the cleaning device will directly affect the quality of corn harvest. At present, in order to improve the cleaning performance of the cleaning device, most of them at home and abroad only improve the sieve structure and fan, ignoring the uniformity of the shaking plate feeding and the influence of the material thrown in the cleaning room on the cleaning effect. In production practice, due to the uneven feeding amount of corn ...

Problems solved by technology

At present, in order to improve the cleaning performance of the cleaning device, at home and abroad, most of them only improve the sieve structure and the fan, ignoring the uniformity of the shaking plate feeding and the influence of the materials thrown in the cleaning room on the cleaning effect.

In production practice, due to the uneven feeding amount of corn materials and the non-adjustable vibration frequency of the shaking plate, it is easy to cause material accumulation on the front end of the shaking plate and the cleaning screen, and it is difficult to ensure and realize the high quality of corn kernels Cleaning operation, and the operation efficiency is low
