Vibrating screen operation detection device

Abstract

The invention provides a vibrating screen operation detection device. A vibrating screen comprises springs, motors, vibrating screen running wheels and a screen box, wherein the springs and the motors are mounted on supports, the vibrating screen running wheels are driven by the motors through driving belts, and the screen box is connected with the vibrating screen running wheels. The vibrating screen operation detection device is characterized by comprising a cross universal joint transmission mechanism, a rotating detection part and a motor control part; the cross universal joint transmission mechanism is connected with the vibrating screen running wheels and transmits the rotating state of the vibrating screen running wheels to the rotating detection part; the rotating detection part is connected with a circuit of the motor control part through a signal line. The vibrating screen operation detection device not only can provide signals of the vibrating screen on a normal working condition and on a fault condition for operators, facilitate operation and avoid production accidents, but also can power off a power supply of the motors driving the vibrating screen in time when the vibrating screen breaks down and prevent sliding friction between the driving belts and the vibrating screen running wheels or between the driving belts and motor running wheels, thereby protecting vibrating screen equipment.

Description

technical field [0001] The invention relates to a transmission detection device, in particular to a vibrating screen operation detection device. Background technique [0002] Vibrating sieve is the most common type of sieving machine in industrial applications. It is a machine that uses a vibrating porous working surface to classify mixed materials with different particle sizes according to particle size. Materials pass through the sieve holes of the sieve surface and can be divided into several grades according to the requirements of particle size. This classification operation is called sieving. In addition to being used for grading, vibrating screens are also commonly used for dehydration of materials, that is, removing moisture from materials; de-mediation, that is, washing with water in a sieve machine and recovering dense medium particles. Vibrating screens are also commonly used for cleaning sludge on the surface of materials. According to different screening tasks, ...

Problems solved by technology

[0005] The device disclosed in the utility model patent application No. CN88219829.7 with the invention name "belt slip monitoring switch" uses the centrifugal force when the rotating shaft rotates to make the contacts connected, but during the operation of the equipment, the transmission part and the detection part It is always in a state of friction, so the device needs to be adjusted regularly, and the service life is short

In addition, its transmission part is not suitable for the working wheel of the vibrating screen that rotates in a small range around its own rotating shaft, which brings troubles to the actual application on site.
