A cleaning sieve fish scale sieve detection device and method

Abstract

A cleaning sieve fish scale sieve detection device and method for detecting the opening of the cleaning sieve fish scale sieve, the cleaning sieve fish scale sieve detection device includes: a frame; the detection mechanism includes two linear sliding frames, symmetrical Installed on both sides of the top of the frame and arranged along the length direction of the frame, each linear sliding frame includes a sliding bracket and a sliding plate, the sliding bracket is installed on the frame, the sliding plate is installed on the sliding bracket and along the The sliding bracket moves synchronously; the driving mechanism is connected with the linear sliding frame; the sliding frame is installed on the sliding plate at both ends; the laser displacement sensor is installed on the sliding frame; the elastic flattening mechanism corresponds to the laser displacement sensor Installed on the sliding frame, it is used to eliminate the movement gap in the adjustment process; and the control display mechanism includes a display and a controller, and the controller is respectively connected with the detection mechanism and the display. The invention also provides a detection method of the detection device.

Description

technical field [0001] The invention relates to an agricultural machinery detection device and method, in particular to a cleaning sieve fish scale sieve detection device and method for quickly detecting the opening of fish scale sieves. Background technique [0002] At present, the staple food crops have basically achieved mechanized harvesting, but domestic harvesters still have problems such as poor reliability, short trouble-free operation time and poor harvesting effect, among which high loss rate and low cleaning rate are the two most prominent problems. Cleaning rate and loss rate are the main evaluation indicators of combine harvester performance, cleaning loss is one of the main sources of mechanical harvesting loss, and poor manufacturing quality is the main reason why cleaning performance cannot meet the standard. Therefore, effective control of the manufacturing quality of the cleaning device is an effective means to improve the cleaning rate and reduce the loss ...

AI Technical Summary

Problems solved by technology

Due to the movement gap in the adjustment process, some sieves cannot be fully seated after adjustment. Although it does not affect the cleaning operation, it is easy to be misjudged by the inspectors.

The efficiency of manual detection is low, the number of sampling points is small, and the sampling is random, which cannot accurately measure the processing quality of the whole sieve
