Embodiment 1

[0030] Open a 250×300mm square hole at the appropriate position of the coal chute 4, install a piece of 300×400mm adhesive tape, and then install an AZ-7121 travel switch 3, and electrically connect the travel switch 3 to the belt conveyor 5 coal level switch .

[0031] After the transformation was completed on January 20, 2016, the accident that the head 6 of the belt machine was often buried and the difficulty of dredging the coal chute 4 were completely solved, the production efficiency was greatly improved, the operation safety of the belt machine was ensured, and the extension the service life of the equipment. Reduce the labor intensity of employees and improve production efficiency. In the half a year after the transformation, there was no accident that the head 6 of the tape machine was buried in the screening system, directly saving more than 50 hours. 500 tons of raw coal are selected per hour, and the price of each ton of raw coal is 150 yuan, directly creating mo...

Abstract

The invention discloses a rubber belt conveyor coal position protection system of a mine sieving system. The rubber belt conveyor coal position protection system comprises a coal chute, an elastic part and a travel switch, wherein a side plate of the coal chute is provided with an opening, and the coal chute is located above a coal slip hole; the shape of the elastic part is the same as that of the opening, and the area of the elastic part is greater than that of the opening; the edge of the elastic part is connected to the side plate of the coal chute through bolts and completely covers the opening; the travel switch is mounted on the elastic part and is triggered through raw coal blocking in the coal chute and squeezing outwards; the travel switch is electrically connected to a circuit of an original rubber belt conveyor coal position switch and used for controlling switch-in and switch-off of the rubber belt conveyor coal position switch. The rubber belt conveyor coal position protection system can conduct cleaning and unchoking within the shortest time, and more time is saved. The rubber belt conveyor coal position protection system is low in cost, simple in structure, convenient to install and maintain and long in service life. The accident that a rubber belt conveyor machine head is buried is avoided. Safety operation of equipment is ensured, and the service life of the equipment is prolonged.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of mine production, in particular to a belt conveyor coal level protection system in a coal mine screening system. [0003] 【Background technique】 [0004] Due to the unreasonable installation position of the original design of the coal pile protection switch of the belt conveyor in the coal mine screening system, when the coal level switch is protected, the coal has already buried the machine head, and the narrow and long coal chute has caused serious damage to the cleaning and dredging work. Great difficulty and inconvenience seriously affect the operation of the system. [0005] 【Content of invention】 [0006] The purpose of the present invention is to provide a belt conveyor coal level protection system in a coal mine screening system to solve the problem that a large number of coal chutes are blocked and buried machine heads. [0007] The present invention adopts the following technical solutions: the b...
