Description

Technical Field

[0001] The utility model belongs to the field of mining machinery and equipment and accessories, in particular to the cleaning of a belt conveyor in a weakly cemented coal formation. Background Art

[0002] Belt conveyor is one of the important tools for transporting coal resources in coal mines, especially in weakly cemented strata. The use of belt conveyor will greatly improve production efficiency and save a lot of labor costs. However, in the process of transporting coal by belt conveyor, due to the harsh underground environment and long-term operation, the belt of belt conveyor is easy to stick to coal slag and soil. Dust is particularly obvious in underground mining of weakly cemented strata, so the existence of belt cleaner is very necessary.

[0003] The original cleaner of the belt conveyor is expensive, with a complex structure, easy to rust and damage, and is not suitable for use in the harsh environment of humidity, water, and high pH in the mine. The existing belt cleaning devices on the market usually use scrapers and brushes for cleaning, which are severely worn and will damage the belt. There are also some improved and perfected belt cleaners, but due to their complex structure, precise instruments, high cost, short service life, or because of the safety hazards caused by the use of electric drive and high failure rate, they cannot meet the needs of production operations.

The cleaning system is used for cleaning the belt conveyor, the connection system is used to connect the cleaning system with the storage system, the power system is used to provide automatic replenishment of the belt and provide support force, and the storage system is used to store slag and maintain the stability of the device.

[0006] Preferably, the cleaning system is composed of a cleaning belt, an I-beam, a steel casing, and bolts and nuts for connection, and the cleaning system is the core structure of the device. The cleaning belt is made of a mining belt, which is wear-resistant, has good supporting force, can be deformed and easily fit the conveyor belt, and can play a good cleaning role. A rectangular belt is cut from a discarded belt as a cleaning belt. The bottom of the belt is symmetrically punched with two I-beams and fixed with bolts and nuts. The end of the belt is in contact with the conveyor belt by the end of the steel casing facing the center of the conveyor shaft, which is used to clean the conveyor belt; the I-beam is used to fix and push the cleaning belt. Two I-beams with the same length as the long side of the cleaning belt are aligned with the long side of the cleaning belt. Holes are drilled in the groove of the I-beam and the three are fixed by bolts and nuts. When the I-beam is pushed upward by the hydraulic support, the cleaning belt rises synchronously with it to achieve The steel shell is welded from steel plates with narrow ends and wide bottoms. The ends are belt outlets and are designed to be very narrow, just enough to support the passage of the cleaning belt. The cleaning belt is not easy to bend or deform when it moves at the end of the steel shell, and plays a role in fixing and supporting the cleaning belt. The bottom is a container for installing hydraulic struts, I-beams and belts, and holes are drilled in the bottom plate to install hydraulic pipes. A rotating shaft is installed at the connection between the end and the bottom of the steel shell, so that the upper steel plate can be opened and closed for the installation of belt debugging and maintenance equipment, and the steel plate is fixed with a screw when closed.

By adjusting the position of the equal-strength nut, the degree of fit between the cleaning system of the cleaner and the belt of the belt conveyor is controlled.

[0008] Preferably, the power system consists of a hydraulic device. The hydraulic support is placed at the bottom of the steel shell, and the belt is automatically replenished upward by pushing the I-beam; the hydraulic pump and control station are set at the bottom corner of the coal retaining chute. The cleaning system belt can be controlled to move up and down by setting hydraulic parameters, so as to adjust the cleanliness of the belt and automatically replenish the belt after consumption; in order to easily identify different adhesives of the belt, the hydraulic system allocates different powers to push the I-beam for the three different working conditions of mining, excavation and transportation to adapt to the complex working conditions of underground mining in weakly cemented formations.

It should be understood that within the technical features and ideas of the utility model, any technical means and ideas for changing, replacing, adding or reducing the invention should be within the protection scope of the invention.

[0025] like Figure 1-12 As shown, a belt cleaning device for a belt conveyor used in a weakly cemented tunnel mine includes four systems: ① cleaning system 1; ② connection system 2; ③ power system 3; ④ material storage system 4;

[0026] The cleaning system is composed of an I-beam 103, a cleaning belt 101, a steel casing 102 and bolts and nuts for connection. The bottom of the cleaning belt 101 is made of two I-beams 103 that are fitted together and punched with holes and fixed with bolts and nuts. The end extends out from the narrow side of the steel casing for cleaning the conveyor belt. A hydraulic support is provided under the I-beam 103.

[0027] The connection system 2 is composed of an equal strength nut 202, an equal strength anchor rod 201 and a steel pipe. The end of the equal strength anchor rod 201 is welded to the steel shell, and the bottom passes through the steel pipe and is fixed by two equal strength nuts 202. The steel pipe is welded to the coal retaining trough.

[0028] The power system 3 is composed of a hydraulic device, and the hydraulic support is placed at the bottom of the steel shell 102. It can realize the autonomous upward replenishment of the cleaning belt 101 in different working conditions such as mining, excavation, and transportation by pushing the I-beam 103; the hydraulic pump 301 and the control station 302 are set at the bottom corner of the coal retaining chute.

[0029] The storage system 4 is welded from four steel plates, three of which are used as coal baffles and one is used as a base, forming a container with a three-way opening on one side of the baffle. The side without the baffle faces the direction in which workers pass through. The coal baffle trough is arranged in front of the belt conveyor, and a fixed steel pipe 203 is vertically welded in the middle of the steel plate close to the belt conveyor.

[0030] The device can control the cleaning belt 101 of the cleaning system 1 to move up and down by setting hydraulic parameters, thereby adjusting the cleaning degree of the belt and automatically replenishing the cleaning belt 101 after it is consumed.

[0031] The steel shell 102 is welded from steel plates, with narrow ends and wide bottoms. The ends are outlets for the cleaning belt 101, which fix and support the cleaning belt 101. The bottom is a container for installing hydraulic struts, I-beams 103 and the cleaning belt 101, and holes are drilled in the bottom plate to install hydraulic pipes. A rotating shaft is installed at the connection position between the end and the bottom of the steel shell 102, so that the upper steel plate can be opened and closed for installation of the cleaning belt 101 and debugging and maintenance equipment. The steel plate is fixed with a screw when closed. A rectangular window is cut on the side of the steel shell 102, and tempered glass is installed for workers to observe the consumption level of the cleaning belt 101.

[0032] After the belt conveyor cleaning device is assembled, place it in front of the lower belt of the belt conveyor, adjust the cleaning device position and adjust the connection system and other strong nuts, so that the cleaning belt at the end of the cleaning system of the device is facing the center of the conveyor shaft, set the hydraulic parameters to give the cleaning belt an upward main force and keep it in close contact with the conveyor belt, such as Fig.11 shown.

[0033] When the belt conveyor starts working, coal, gangue, etc. are transported out of the working face through the upper belt. Dirt and coal ash will stick to the belt. When the belt enters the lower position and contacts the leather strip at the end of the cleaning device, the dirt and coal ash sticking to the belt falls off through the friction and scraping effect of the cleaning belt on the conveyor belt. The fallen dirt and coal ash enters the coal retaining trough. When the dirt and coal ash in the coal retaining trough accumulates to a certain amount, the workers clean and transport out the waste on the side without the baffle to clean the belt of the belt conveyor.

[0034] Workers regularly check the consumption of the cleaning belt and the hydraulic parameters of the power system, replace the cleaning belt and replenish the hydraulic oil in time to ensure the normal operation of the belt cleaning device of the belt conveyor.

[0035] The technical features of the above-described embodiments may be arbitrarily combined.
