Description

Technical Field

[0001] This utility model belongs to the field of mining technology, and in particular relates to a sorting and filtering device for mining. Background Technology

[0002] Coal mining sorting and filtering equipment is a device used to sort and filter coal during the coal mining process. This device typically includes a support frame, a material distribution mechanism, a screening mechanism, and a chain conveyor mechanism. It can achieve full screening and separation of coal, improve screening efficiency, and thus improve coal quality and production efficiency.

[0003] Chinese Patent Publication No. CN210523245U discloses a coal mine cleaning device with screening function, including a support frame. A cleaning device is fixedly connected to the top of the support frame, a filter bucket is fixedly connected to the middle of the support frame, and a recovery box is fixedly connected to the bottom of the support frame. A screening box is located on the left side of the recovery box, and the screening box has an internal cavity. This coal mine cleaning device with screening function uses a cleaning motor to drive the cleaning blades to rotate, thereby stirring the mixture of coal and water. Thorough stirring ensures effective cleaning of the coal. The device is simple to operate, environmentally friendly, and pollution-free, improving coal utilization and increasing profits. After cleaning, the coal is sequentially screened by the screening device to separate coal of different volumes, facilitating subsequent processing and improving coal utilization and economic efficiency.

[0004] However, the above structure still has shortcomings. The device uses the rolling of coal ore on an inclined screener under gravity to make coal ore of different sizes fall into the screening holes of the screener to screen the coal ore according to its size specifications. However, when the surface of the coal ore tends to be flat, it moves slowly when rolling on the inclined screener, resulting in slow screening efficiency.

[0005] Therefore, it is necessary to provide a new sorting and filtering device for mining operations to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a sorting and filtering device for mining that can uniformly distribute coal and increase vibration during coal ore screening to effectively improve the efficiency of rolling screening.

[0007] To solve the above-mentioned technical problems, the present invention provides a sorting and filtering device for mining operations, comprising: a C-shaped support rod, two vertical support rods on one side of the C-shaped support rod, a reinforcing rod fixedly connected between the vertical support rod and the C-shaped support rod, a screening mechanism on the C-shaped support rod, and a conveying mechanism on one side of the C-shaped support rod;

[0008] The screening mechanism includes a screener located below a U-shaped support rod. Two hinge blocks are fixedly installed on the screener and are rotatably hinged to the vertical support rod. Two mounting rods are fixedly connected to the U-shaped support rod, and a transmission rod is rotatably mounted on each mounting rod. Discs are fixedly installed at both ends of the transmission rod, and pins are fixedly installed on each disc. A hinge rod is rotatably hinged to each pin, and one end of the hinge rod is rotatably hinged to the screener.

[0009] The conveying mechanism includes a support plate disposed above one side of the screen. Four support blocks are fixedly installed on the support plate, and a support frame is fixedly installed between two support blocks. Four fixed rods are fixedly installed on the support plate, and a transmission roller is rotatably installed between two fixed rods. A conveyor belt is wound between two transmission rollers. A second motor is fixedly installed on the corresponding fixed rod, and the output end of the second motor is fixedly connected to the corresponding transmission roller. A baffle plate is fixedly installed on the support block and is located on one side of the conveyor belt.

[0010] A connecting rod is fixedly installed between the two guard plates, and three material distribution rods are fixedly installed on the connecting rod.

[0011] A first motor is fixedly installed on the C-shaped support rod, a first pulley is fixedly installed at the output end of the first motor, a second pulley is fixedly sleeved on the transmission rod, and a transmission belt is wound between the second pulley and the first pulley.

[0012] As a further embodiment of this utility model, three receiving boxes are provided below the screener, and four rolling wheels are installed below the receiving boxes, with the four rolling wheels arranged in a rectangular array along the receiving boxes.

[0013] As a further embodiment of this utility model, the screener is provided with small sorting holes, medium sorting holes and large sorting holes, and the medium sorting hole is located between the small sorting holes and the large sorting holes.

[0014] Compared with related technologies, the sorting and filtering device for mining provided by this utility model has the following advantages:

[0015] 1. This utility model is equipped with a screening mechanism, which enables the screener to swing up and down around the hinge of the hinge block and the vertical support rod as the axis, thereby causing the coal ore on the screener to shake, improving the rolling efficiency of the coal ore, and facilitating the rapid falling of the coal ore into the screening holes on the screener, thus effectively improving the screening efficiency.

[0016] 2. This utility model is equipped with a material conveying mechanism, which allows the conveyor belt to move the coal ore closer to the material distribution bar. The material distribution bar then disperses the accumulated coal ore, making it easier for the dispersed coal ore to fall evenly onto the screen, which is beneficial for the screening of the coal ore.

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a first three-dimensional structural schematic diagram of the sorting and filtering device for mining according to this utility model; Figure 2 A second three-dimensional structural schematic diagram of the sorting and filtering device for mining provided by this utility model; Figure 3 This is a schematic diagram showing the disassembled structure of the conveying mechanism of the sorting and filtering device for mining provided by this utility model. The sorting and filtering device for mining includes: a C-shaped support rod 1, two vertical support rods 101 arranged on one side of the C-shaped support rod 1, a reinforcing rod 102 fixedly connected between the vertical support rods 101 and the C-shaped support rod 1, a screening mechanism arranged on the C-shaped support rod 1, and a conveying mechanism arranged on one side of the C-shaped support rod 1;

[0023] The screening mechanism includes a screener 2, which is located below the U-shaped support rod 1. Two hinge blocks 201 are fixedly installed on the screener 2. The hinge blocks 201 are rotatably hinged to the vertical support rod 101. Two mounting rods 3 are fixedly connected to the U-shaped support rod 1. A transmission rod 301 is rotatably installed on the mounting rod 3. A disc 302 is fixedly installed at both ends of the transmission rod 301. A round pin 303 is fixedly installed on the disc 302. A hinge rod 304 is rotatably hinged to the round pin 303. One end of the hinge rod 304 is rotatably hinged to the screener 2.

[0024] like Figure 2 and Figure 3 As shown, the conveying mechanism includes a support plate 5, which is disposed on one side of the screener 2. Four support blocks 501 are fixedly installed on the support plate 5, and a support frame 502 is fixedly installed between two support blocks 501. Four fixing rods 503 are fixedly installed on the support plate 5, and a transmission roller 504 is rotatably installed between two fixing rods 503. A conveyor belt 505 is wound between two transmission rollers 504. A second motor 506 is fixedly installed on the corresponding fixing rod 503. The output end of the second motor 506 is fixedly connected to the corresponding transmission roller 504. A baffle plate 507 is fixedly installed on the support block 501 and is located on one side of the conveyor belt 505.

[0025] After the second motor 506 is powered on and started, it can drive the corresponding transmission roller 504 to rotate. Then the transmission roller 504 drives the conveyor belt 505 to move and transport the coal ore above.

[0026] like Figure 3 As shown, a connecting rod 6 is fixedly installed between the two baffle plates 507, and three material distribution rods 601 are fixedly installed on the connecting rod 6;

[0027] By setting up the material distribution bar 601, the coal ore conveyed on the conveyor belt 505 can be dispersed after passing through the material distribution bar 601, and the coal ore is evenly dispersed for easy screening.

[0028] like Figure 1 As shown, a first motor 4 is fixedly installed on the C-shaped support rod 1, a first pulley 401 is fixedly installed on the output end of the first motor 4, a second pulley 402 is fixedly sleeved on the transmission rod 301, and a transmission belt 403 is wound between the second pulley 402 and the first pulley 401.

[0029] After the first motor 4 is powered on and started, it can drive the first pulley 401 to rotate. Then, the first pulley 401 drives the second pulley 402 to rotate through the transmission belt 403. Then, the second pulley 402 drives the transmission rod 301 to rotate, thus achieving the transmission of kinetic energy.

[0030] like Figure 2 As shown, three receiving boxes 7 are provided below the screener 2, and four rollers 701 are installed below the receiving boxes 7. The four rollers 701 are distributed in a rectangular array along the receiving boxes 7.

[0031] By setting up a receiving box 7, the screened coal ore can be collected, and then the receiving box 7 can be easily moved out from under the screener 2 by the rolling wheel 701.

[0032] like Figure 1 As shown, the filter 2 has small sorting holes, medium sorting holes and large sorting holes, with the medium sorting hole located between the small sorting hole and the large sorting hole;

[0033] Coal ore can be sorted into three sizes—small, medium, and large—using the small, medium, and large sorting holes set on screen 2.

[0034] The working principle of the sorting and filtering device for mining provided by this utility model is as follows:

[0035] First step: After the second motor 506 is powered on and started, it drives the corresponding transmission roller 504 to rotate. Then the transmission roller 504 drives the conveyor belt 505 to transport the coal ore. After the conveyor belt 505 transports the coal ore through the material distribution bar 601, it can evenly disperse the coal ore and let it fall onto the screener 2.

[0036] The second step: The first motor 4 is powered on and drives the first pulley 401 to rotate. Then, the first pulley 401 drives the second pulley 402 to rotate through the transmission belt 403. The second pulley 402 then drives the transmission rod 301 to rotate, causing the discs 302 at both ends of the transmission rod 301 to rotate. When the discs 302 rotate, they drive the pins 303 to rotate around the transmission rod 301. The pins 303 can then drag one end of the hinge rod 304 to rotate, causing the other end of the hinge rod 304 to move up and down. The other end of the hinge rod 304 can then drive the screen 2 to rotate and swing up and down around the hinge between the hinge block 201 and the vertical support rod 101, increasing the shaking of the coal ore on the screen 2. This helps the coal ore to roll quickly into the screening holes, improving the coal ore screening efficiency.
