Description

The device relates to agricultural machinery, in particular to devices for controlling the operation of grain cleaning machines.

A device is known for monitoring the operation of grain cleaning machines, which contains a sensor for the passage of grain located below, separating it with a surface and a funnel 1 installed above it.

However, the known device is characterized by insufficient control accuracy due to the possibility of multiple impacts of the same grain on the membrane.

The purpose of the invention is to improve the accuracy of control.

The goal is achieved by the fact that the device is equipped with directions fixed rigidly in parallel to the separating surface, on which a grain passage sensor is installed, made in the form of a photoelectric counter, while the funnel is fixed on the sensor.

The drawing shows the proposed device, general view.

The device contains a photoelectric meter 1 with a funnel 2, placed on the tracks 3, rigidly connected to the separating surface 4 for separating the grain 5.

The device works as follows.

The grain that has passed through the separating surface 4 enters the funnel 2 of the photoelectric counter 1. The grain 5, the passage through the funnel 2 and the counter 1, are counted. In normal mode, the number of grains 5 corresponds to the specified. If the number of grains decreases or increases, the operator intervenes in the process and the regulator (not shown) changes the amount of grain entering the screen in the appropriate direction depending on the signal from counter 1.

Installing the sensor on the guide 3 sieves parallel to them allows the photoelectric counter 1 to be as close as possible to the separating surface 4, which, in combination with the funnel 2, eliminates the possibility of airborne grains 5 from the uncontrolled area.

Moving the counter 1 with the funnel 2 along the guides 3, parallel to the separating surface 4, the operator selects a section of the sieve with a characteristic passage indicator for a certain productivity and culture.

Using the proposed device allows you to more accurately judge the mode of loading of the grain cleaning machine and maintain it at the maximum level with an acceptable degree of cleaning.
