Embodiment Construction

[0021] The specific implementation of the device for measuring the height of the blanking pile of the present invention is provided below, and an example is provided, but the present invention is not limited to the provided example.

[0022] See attached figure 1 and 2 . The device 6 includes a protective fixing device 1 , a swing angle detection device 2 , a swing shaft 3 , a pendulum 4 and a signal output device 5 . The free swinging device adopts a fan-shaped steel sheet, and the plane of the steel sheet is aligned with the flow direction of the material 7 to increase the sensitivity of perception, and the magnetic steel is fixed on the upper end of the pendulum; the swing angle detection device uses a reed switch; the signal output is connected to the reed switch electrical contacts. When there is enough material flow on the conveyor belt 8, the material drives the fan-shaped steel sheet to lift an angle, so that the magnetic steel on the pendulum is far away from the r...

Abstract

The invention discloses a material disconnection warning device for a conveyer belt, which comprises a protective fixing device, a free swing device, a swing angle detecting device and a signal output device. The protective fixing device is used for mounting the free swing device, the swing angle detecting device and the signal output device, and provides protection function at the same time; the free swing device comprises a shaft and a pendulum, wherein the shaft is fixed on the protective fixing device, the pendulum can rotate around the shaft within a certain angle, the angle changes along with change of thickness of a material on the conveyer belt, and length and shape of the pendulum are selected according to size of the conveyer belt; and the signal output device is used for providing warning signal output, and sometimes, the swing angle detecting device has single output function synchronously.

Description

【Technical field】 [0001] The invention relates to a material cut-off alarm device, in particular to a material cut-off alarm device for a conveyor belt which sends out an alarm signal according to measuring the amount of material on the conveyor belt. 【Background technique】 [0002] In the chemical industry, metallurgy, coal, electric power, agriculture and other industries, in the process of conveying materials, it is often necessary to measure the amount of materials on the conveyor belt. If the flow rate on the conveyor belt decreases, it needs to automatically alarm in time. [0003] The existing measurement methods are: belt scale, nuclear scale, tilt switch, ultrasonic coal flow detector, coal blocking switch. [0004] The belt scale directly measures the weight of the material on the conveyor belt, which is greatly affected by the tension of the belt and is expensive. The accuracy is low, and the error is large when the material is uneven. In addition, various dynami...
