Problems solved by technology

Although these backstops can prevent the conveyor belt from slipping backwards, they do not have the function of blocking coal. Some coal can still enter between the conveyor belt and the rollers, and the wheels will cause serious accidents such as deviation, prolapse or even breakage of the conveyor belt

Embodiment

[0017] A kind of coal conveyor belt non-return device, such as figure 1 , figure 2 As shown, it is arranged above the conveyor belt 9, and a roller 8 connected to the motor is provided below the conveyor belt 9, and the roller 8 drives the conveyor belt 9 to rotate up and down, and a conveyor belt bracket 7 is also provided below the conveyor belt 9. The non-return device includes Baffle support 6, steel baffle 3, electromagnet 1 and controller 10, baffle support 6 is arranged on the both sides of conveyer belt 9, and is positioned at the middle and lower part of conveyer belt 9, and baffle support 6 and conveyer belt 9 surface Vertically, the electromagnet 1 is located at the top of the baffle bracket 6, and when the electromagnet 1 is energized, it will hold the steel baffle 3 so that the steel baffle 3 is located at the top of the baffle bracket 6, and when the electromagnet 1 is powered off, the steel baffle 3 will fall Intercept the lump of coal on the conveyor belt 9 o...

Abstract

The invention relates to a non-return device of a coal loading conveyor belt. The non-return device is arranged above the conveyor belt; rolling wheels which are connected with a motor are arranged under the conveyor belt; the rolling wheels drive the conveyor belt to rotate up and down, and a conveyor belt support is also arranged under the conveyor belt. The non-return device comprises a baffle plate support, a steel baffle plate, an electromagnet and a controller, wherein the baffle plate support is arranged at two sides of the conveyor belt and is vertical to the surface of the conveyor belt; the electromagnet is arranged at the top end of the baffle plate support; the steel baffle plate is sucked by the electromagnet and is enabled to be positioned at the top end of the baffle plate support when the electromagnet is powered on; the steel plate falls onto the conveyor belt to intercept coal sheet on the conveyor belt when the electromagnet is powered off, and the controller is arranged on the conveyor belt support and controls the powering on and off of the electromagnet. Compared with the prior art, the non-return device has the advantages that the structure is simple, the reaction is sensitive, the use is convenient, the hidden danger that equipment is damaged as an electric apparatus is in failure can be effectively avoided, the service life of the equipment is prolonged, and the labor intensity and the time for cleaning the rolling wheels can be reduced.

Description

technical field [0001] The invention relates to an auxiliary device for a conveyor belt, in particular to a non-return device for a coal loading conveyor belt. Background technique [0002] In the existing coal loading system, the coal is transported upwards into the coal hopper through the conveyor belt along an angle of about 30°. The conveyor belt is conveyed upwards completely by the friction force of the motor-driven rollers. In the process of feeding coal, if there is an electrical failure or special failure, the motor stops or the rollers reverse, the conveyor belt will slide backwards, the coal on the conveyor belt will pour down, and the coal will overflow into the rollers, causing the conveyor belt to deviate and fall out. Even severe accidents such as breakage. [0003] Some existing belt backstops located on the coal conveyor belt are used as protective devices for preventing the reverse rotation of the mechanical transmission mechanism during an emergency. Al...
