Description

Technical Field

[0001] The utility model belongs to the technical field of transmission equipment, and particularly relates to a coal mine material transmission equipment. Background Art

[0002] A coal mine refers to a place rich in coal resources, generally divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally choose to dig underground roadways to mine coal, this is an underground coal mine. When the distance between the coal seam and the surface is very close, generally choose to directly strip the surface soil layer to mine coal, this is a surface coal mine. After coal mining, transportation is required, and usually the conveyor belt method is used for transportation.

[0003] When the existing coal mine material transmission equipment is used for transmission on a large slope, the following problems are likely to occur:

[0004] 1. The relative slip between the conveyor belt and the transmission shaft makes it impossible to transport materials.

[0005] 2. The traditional conveyor belts are generally flat, and the amount of materials transported at one time is small, and the materials are easy to slide off from both sides of the conveyor belt.

[0006] 3. The conveyor belt is prone to deviation, resulting in abnormal wear of the conveyor belt. Content of the Utility Model

[0007] The purpose of the utility model is to provide a coal mine material transmission equipment for solving the problems mentioned in the background art.

[0008] To achieve the above technical purpose, the technical scheme adopted by the utility model is as follows:

[0009] A coal mine material transmission equipment, including a base, the base is inclined upward from left to right, and a conveyor belt is installed on its upper side. The perimeter of the conveyor belt gradually shrinks from both sides to the middle. A plurality of front and rear inclined support rollers are evenly installed on the lower side of the upper surface of the conveyor belt. The support rollers are rotationally connected to the base and are matched with the conveyor belt. A chain matching the conveyor belt is fixed on the inner side of the upper surface of the conveyor belt. Sprockets rotationally connected to the base and meshing with the chain are installed on both left and right sides of the base. A group of tapered wheels are rotationally installed on both left and right sides of the base. The number of each group of tapered wheels is two and they are symmetrically distributed front and rear. The tapered wheels are matched with the conveyor belt and are in transmission connection with the sprockets at their corresponding positions. A power unit is installed on the side of the base, and the output end of the power unit is in transmission connection with the sprocket.

[0010] An auxiliary sprocket meshing with the upper side of the chain is installed in the middle of the base. A power unit fixedly connected to the base is installed on the side of the auxiliary sprocket, and the output shaft of the power unit is in transmission connection with the auxiliary sprocket.

[0011] A plurality of anti-skid plates are evenly distributed on the left and right sides of the upper side of the outer belt surface of the transmission belt, and the lower side of the anti-skid plate matches the shape of the transmission belt and is fixedly connected thereto.

[0012] Baffles fixedly connected to the base are installed on the front and rear sides of the transmission belt. The two baffles are inclined downward from the outside to the inside and the bottoms are matched with the transmission belt.

[0013] Brackets are hinged on the left and right sides of the lower left side of the base, a guide chain wheel matching the chain is rotatably installed on the lower side of the bracket, and a tension spring is installed between the right side of the bracket and the base.

[0014] A plurality of cover plates linearly distributed left and right are hinged up and down on the upper side of the baffle.

[0015] The coordination of the sprocket and the chain can ensure efficient transmission between the power unit and the transmission belt, help reduce energy loss, improve the efficiency of the overall mechanical system, and avoid slippage between the power unit and the transmission belt. There are two conical wheels in each set, which are symmetrically distributed front and back, and are connected to the sprockets at the corresponding positions, which further enhances the transmission effect, avoids the deviation of the transmission belt, reduces the friction between the belt and the base, and prolongs the service life. In addition, the circumference of the conical wheels and the transmission belt that are symmetrically distributed front and back gradually decreases from both sides to the middle. This design allows the belt to more effectively gather materials to the middle during operation, avoid materials from slipping from the front and back sides, and enable the transmission belt to transport more coal and mineral materials at one time. The coordination of the auxiliary sprocket and the auxiliary power unit allows users to freely combine and adjust the layout of the transmission belt according to actual needs. When a single power unit fails, other power units can continue to Work, reducing downtime caused by failures. In addition, multiple power units can also achieve redundant design, further improving the reliability and stability of the system. The anti-skid plate helps to increase the friction between the material and the belt, preventing the material from slipping along the direction of the transmission belt during transmission; inclined baffles are installed on the front and rear sides of the transmission belt, which is convenient for loading the transmission equipment while further preventing the material from falling from the front and rear sides of the transmission belt during transmission. The cooperation of the bracket, guide sprocket and tensioning spring enables the chain to maintain appropriate tension during operation, avoiding transmission failures caused by chain relaxation and slot jumping, further ensuring the stability and reliability of the equipment's operation. The multiple linearly distributed covers on the upper and lower sides of the baffle are hinged, which can isolate the dust generated by the coal and mineral materials during the transmission process when in use, and can also be opened or closed as needed, so as to clean the transmission belt or perform maintenance operations when necessary.

[0022] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] As Figures 1-4 shown, a coal mine material transmission device includes a base 1. The base 1 slopes upward from left to right, and a transmission belt 2 is installed on its upper side. The perimeter of the transmission belt 2 gradually decreases from both sides to the middle. A plurality of front-to-back inclined support rollers 3 are evenly installed on the lower side of the belt surface of the transmission belt 2. The support rollers 3 are rotatably connected to the base 1 and are matched with the transmission belt 2. A chain 4 matching the transmission belt 2 is fixed to the inner side of the belt surface of the transmission belt 2. Sprockets 5 rotatably connected to the base 1 and meshing with the chain 4 are installed on both left and right sides of the base 1. A set of tapered wheels 6 are rotatably installed on both left and right sides of the base 1. The number of each set of tapered wheels 6 is two and they are symmetrically distributed front and back. The tapered wheels 6 are matched with the transmission belt 2 and are drivingly connected to the sprockets 5 at their corresponding positions. A power unit 7 is installed on the side of the base 1. The output end of the power unit 7 is drivingly connected to the sprocket 5.

[0024] In the present utility model, the power unit 7 installed on the side of the base 1 provides power for the entire transmission system, and its output end is drivingly connected to the sprocket 5, ensuring the effective transmission of power. A plurality of front-to-back inclined support rollers 3 evenly installed on the lower side of the belt surface of the transmission belt 2 provide stable support.

[0025] The cooperation between the sprocket 5 and the chain 4 can ensure efficient transmission between the power unit 7 and the transmission belt 2, which helps to reduce energy loss and improve the efficiency of the overall mechanical system. At the same time, it also avoids slipping between the power unit 7 and the transmission belt 2. There are two conical wheels 6 in each group, which are symmetrically distributed front and back, and are connected to the sprocket 5 at the corresponding position, which further enhances the transmission effect, avoids the deviation of the transmission belt 2, reduces the friction between the belt and the base 1, and extends the service life. In addition, the circumference of the conical wheels 6 and the transmission belt 2 that are symmetrically distributed front and back gradually decreases from both sides to the middle. This design enables the belt to more effectively gather materials to the middle when running, avoids materials from slipping from the front and back sides, and enables the transmission belt 2 to transport more coal and mineral materials at one time.

[0026] An auxiliary sprocket 8 meshing with the upper side of the chain 4 is installed in the middle of the base 1 , and an auxiliary power unit 9 fixedly connected to the base 1 is installed on the side of the auxiliary sprocket 8 , and the output shaft of the auxiliary power unit 9 is drivingly connected to the auxiliary sprocket 8 .

[0027] The cooperation between the auxiliary sprocket 8 and the auxiliary power unit 9 allows the user to freely combine and adjust the layout of the transmission belt 2 according to actual needs. When a single power unit 7 fails, other power units 7 can continue to work, reducing downtime caused by the failure. In addition, multiple power units 7 can also achieve redundant design, further improving the reliability and stability of the system.

[0028] A plurality of anti-skid plates 10 are evenly spaced apart on the left and right sides of the outer belt surface of the transmission belt 2, and the lower side of the anti-skid plates 10 matches the shape of the transmission belt 2 and is fixedly connected thereto.

[0029] Baffles 11 fixedly connected to the base 1 are installed on the front and rear sides of the transmission belt 2. The two baffles 11 are inclined downward from the outside to the inside and the bottoms match the transmission belt 2.

[0030] A plurality of anti-skid plates 10 are evenly spaced on the upper side of the outer belt surface of the transmission belt 2, which help to increase the friction between the material and the belt and prevent the material from slipping along the transmission belt 2 during transmission; inclined baffles 11 are installed on the front and rear sides of the transmission belt 2, which not only facilitates the loading of materials onto the transmission equipment, but also further prevents the material from falling from the front and rear sides of the transmission belt 2 during transmission.

[0031] A bracket 12 is hinged on the left and right sides of the lower left side of the base 1, a guide chain wheel 13 matching the chain 4 is rotatably installed on the lower side of the bracket 12, and a tension spring 14 is installed between the right side of the bracket 12 and the base 1.

[0032] The cooperation of the support 12, the guide sprocket 13 and the tension spring 14 enables the chain 4 to maintain an appropriate tension during operation, avoiding problems such as chain 4 slack and derailment, and preventing transmission failures, further ensuring the stable and reliable operation of the equipment.

[0033] A plurality of cover plates 15 linearly distributed left and right are hinged up and down on the upper side of the baffle 11.

[0034] The plurality of cover plates 15 linearly distributed left and right and hinged up and down on the upper side of the baffle 11 can isolate dust generated by coal mine materials during transmission during use, and can also be opened or closed as needed to facilitate cleaning the conveyor belt 2 or performing maintenance operations when needed.
