The scheme of automatic cleaning mechanism for underground conveyor belt blockage in the present invention patent realizes automatic monitoring of the conveyor belt feeding status, automatic siltation cleaning and dredging, and unmanned operation, which reduces the underground manpower allocation and improves the efficiency and safety of underground production.

Description

Technical Field

[0001] The invention relates to the field of underground production and material transportation, and in particular to a solution of an automatic cleaning mechanism for preventing blocking of underground conveyor belts. Background Art

[0002] With the rapid development of the global economy, countries have conducted extensive and in-depth research on the construction of underground belt transportation, especially on reducing the number of underground personnel and realizing the automation of underground transportation. Due to the complexity of the underground tunnel structure, the front and rear conveyor belts need to change a certain angle to maintain the continuous transportation of materials. The change in transportation direction, coupled with the uncertainty of the size of underground coal stones, and the change in humidity and viscosity, causes coal stones and other materials to often accumulate at the head of the conveyor belt of the next station, causing the conveyor belt to run idle. The coal stones pile up higher and higher, causing the line to stop and the production capacity to decrease. Personnel have to be arranged at each corner of the conveyor station to guard and clean up the silted coal stone materials at any time, which increases the number of underground personnel stations, greatly increases personnel safety issues and personnel costs. The current common solution is to place a human guard at each corner station, or a human travels back and forth between 2~3 stations, which cannot solve the problem of reducing labor and real-time processing, and requires major improvements. Summary of the invention

[0003] The purpose of the present invention is to design an automatic cleaning mechanism scheme for preventing underground conveyor belts from being blocked.

[0004] In order to achieve the above-mentioned invention purpose, the technical scheme of the present invention is: an automatic cleaning mechanism scheme for preventing blockage of underground conveyor belts, including a conveyor belt at an upper station, a corner working area, an anti-blocking sensor, an anti-blocking control unit, an anti-blocking actuator, and a conveyor belt at a lower station. The sensor is installed in the corner working area to monitor the height and width of materials such as coal and stone on the conveyor belt in real time. After the sensor signal is processed by the anti-blocking control unit, an instruction is issued to the anti-blocking actuator. The anti-blocking actuator is divided into two units: an actuator baffle part and an actuator push rod part. Both of these actuator units are connected to the power of the motor through a mechanical push rod, so that the actuator baffle swings back and forth and the actuator push rod performs long-distance reciprocating motion. The entire mechanism is fixed in the corner working area and at the head of the lower station conveyor belt through a bracket, that is, the position area connected to the tail of the upper conveyor belt.

[0005] The beneficial effects of the present invention are:

[0006] The present invention has a simple structure and can be installed at each intersection of the conveyor belts underground, completely saving manual labor, improving personal safety underground, reducing enterprise costs, improving continuous productivity, and increasing production, efficiency, reducing staff, and reducing risks for enterprises. In addition to being used underground, the present invention can also be used in any place where conveyor belts are used to transport bulk materials, which can greatly reduce the labor intensity of personnel, reduce the problems of downtime, line stoppage, and reduced production capacity caused by material accumulation and blockage, thereby improving production efficiency.

[0010] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0011] like Figure 1 , 2 As shown in Figure 3, an automatic cleaning mechanism scheme for preventing blockage of underground conveyor belts includes a conveyor belt of an upper station, a corner working area, an anti-blocking sensor, an anti-blocking control unit, an anti-blocking actuator, and a conveyor belt of a lower station. The sensor is installed in the corner working area and distributed in the corner working area at the end of the upper station conveyor belt and the beginning of the lower station conveyor belt, respectively, to monitor the height and width of coal and other materials on the upper station conveyor belt and the lower station conveyor belt in real time. After the sensor signal is processed by the anti-blocking control unit, if it is detected that the height and width of coal and other materials on the conveyor belt show an upward trend and exceed the warning gate value, the control unit will issue a command to the anti-blocking actuator to perform actual silt removal and unblocking operations until the height of coal and other materials on the conveyor belt is lower than the warning gate value, then stop moving and wait for the next command. The anti-blocking actuator is divided into two units that work together: the execution baffle part and the execution push rod part. The two execution units are connected to the power of the motor through mechanical push rods, so that the execution baffle swings back and forth and the execution push rod moves back and forth over a long distance, making the silted coal and other materials loose and easy to be conveyed. The entire mechanism is fixed by a bracket in the corner work area, at the beginning of the lower station conveyor belt, that is, the location area connected to the tail of the upper conveyor belt.

[0012] The described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Claims

1. An automatic cleaning mechanism for preventing blocking of underground conveyor belts, characterized in that: When the conveyor belt needs to be transported at a corner, and the coal and stone materials need to be transferred from the previous conveyor belt to the next conveyor belt with a different transmission angle, an anti-blocking automatic cleaning mechanism is set at the corner intersection. The anti-blocking automatic cleaning mechanism includes the conveyor belt of the upper station, the corner working area, the anti-blocking sensor, the anti-blocking control unit, the anti-blocking actuator, and the conveyor belt of the lower station. The anti-blocking sensor is installed in the corner work area, distributed in the corner work area at the end of the upper station conveyor belt and the beginning of the lower station conveyor belt. The anti-blocking sensor monitors the height and width trend of the coal stone material on the conveyor belt in real time, and transmits the data to the anti-blocking control unit for calculation and processing. When it is detected that the height and / or volume of the coal stone material continues to increase and exceeds the designed gate value, a command is issued to the anti-blocking actuator to perform the actual cleaning operation; the anti-blocking actuator is divided into two units that work together: the actuator baffle unit and the actuator push rod unit. The actuator baffle unit and the actuator push rod unit are connected to the power of the motor through a mechanical push rod, respectively, so that the actuator baffle swings back and forth and the actuator push rod performs a long-distance reciprocating motion, so that the silted coal stone material becomes loose and loose, which is convenient for transmission; When the anti-blocking sensor detects that the height and / or width of the coal stone material on the conveyor belt is lower than the safety gate value, the anti-blocking actuator returns to its original position and waits for the next work.
