A differential speed intelligent non-destructive multi-roller thresher for a corn harvester in a plot

Abstract

The invention discloses a differential-speed intelligent non-destructive multi-roller thresher for a corn harvester in a plot. The thresher is mainly composed of a frame (1), a feeding device (2), a primary threshing device (4), a secondary threshing device, a transmission device, a grain collection device and an intelligent control system. The feeding device (2), the primary The threshing device (4), the secondary threshing device and the grain collecting device are installed on the frame (1) sequentially from top to bottom, and the transmission device makes the primary threshing device (4) and the secondary threshing device rotate and work, intelligently controlled The system detects and records the moisture content of corn ears, and controls the rotating speed of the motor (3). The thresher of the present invention adopts two threshing processes, the intelligent control system detects the moisture content of corn ears, adjusts the rotation speed of the motor (3), and realizes non-destructive threshing of corn. The thresher has a reasonable structure and is easy to use.

Description

technical field [0001] The invention belongs to the technical field of corn harvesting machinery in agricultural plots, in particular to a differential-speed intelligent non-destructive multi-roller thresher for corn harvesters in plots. Background technique [0002] The sown area of ​​corn in China is about 35,000 thousand hectares, and the annual demand for corn seeds is huge. At present, the degree of mechanization in plot breeding of corn varieties is extremely low, resulting in that the cultivation, harvesting and cleaning of corn seeds are mostly done manually, and the work efficiency is low, thus indirectly affecting the price of corn seeds. Traditional corn harvesters have problems such as broken corn kernels, dropped ears, and high loss rates. Therefore, it is impossible to directly use the general corn harvester as the plot corn harvester, and a new corn seed harvester needs to be developed. [0003] The function of the corn harvester in the plot is to harvest, t...
