[0001] The invention relates to the technical field of coal crushing for mining, and in particular to a coal crushing device for mining which is easy to clean. Background Art

[0002] In the mining industry, coal crushing equipment is an indispensable equipment. Mining coal crushing equipment is a device used to break large pieces of coal into smaller particles during coal mining. This equipment plays an important role in coal processing, transportation and use, because smaller coal particles are easier to handle, store and burn.

[0003] Existing coal crushing devices for mining usually crush coal by rotating the crushing wheel. However, since the crushing wheel is located inside the device and is not easy to clean, coal powder and other impurities are easily accumulated during the coal crushing process, affecting the crushing efficiency and equipment life.

[0004] Therefore, a coal crushing device for mining that is easy to clean has been developed, which can clean the crushing wheel in time during the crushing process to avoid affecting the crushing efficiency and the life of the equipment. Summary of the invention

[0007] Furthermore, a material receiving box is provided on the lower side of the base.

[0008] Furthermore, the crushing mechanism includes a frame, a motor, a crank wheel, a gear ring and a crushing wheel. The front side of the lower part of the middle frame is connected to the frame, the upper side of the frame is connected to the motor, the front sides of the left and right parts of the middle frame are rotatably connected to the crank wheels, the rear sides of the left and right parts of the middle frame are also rotatably connected to the crank wheels, the motor output shaft is connected to the adjacent crank wheels, the outer sides of the crank wheels are connected to the gear rings, the two adjacent gear rings are meshed with each other, the left and right parts of the middle frame are rotatably connected to the crushing wheels, and the crank wheels are connected to the adjacent crushing wheels.

[0009] Furthermore, the cleaning mechanism includes a vertical rail, a traction rope, a pulley, a slider, a brush, a compression spring and a guide block. The crank wheel is movably connected to the vertical rail, and two upper and lower traction ropes are connected between two vertically adjacent vertical rails. The front and rear parts of the middle frame are rotatably connected to a plurality of pulleys, the traction rope is in contact with adjacent pulleys, and a slider is connected between two adjacent traction ropes.

The sliders are squeezed and matched with adjacent brushes, and the front and rear parts of the middle frame are connected to left and right guide blocks, and the vertical rails are slidably connected to adjacent guide blocks. When the crank wheel rotates, it pushes the vertical rail to move left and right on the guide block, so that the traction rope moves left and right, and the pulley supports and guides the traction rope. When the traction rope moves left and right, it drives the slider to move left and right, so that the slider squeezes the protrusion of the brush, and the compression spring stretches, so that the brush approaches the crushing wheel.

[0010] Furthermore, the scrub brush is provided with bristles.

[0011] Furthermore, it also includes a crushing mechanism, which includes a convex column, a rail rod, a cross bridge and a crushing block. The lower part of the crank wheel on the left is connected to the convex column, and the rail rod is movably connected to the convex column. The upper side of the rail rod is connected to the cross bridge, and the cross bridge is slidably connected to the top frame. The crushing block is connected between the lower sides of the cross bridge, and the crushing block is located on the upper side of the screen.

When the coal is crushed, the temperature controller is started according to the crushing requirements to cool or heat the temperature control tube to adjust the internal temperature of the middle frame.

[0015] Furthermore, it also includes a flushing mechanism, which includes a fixed plate and a nozzle. The left and right sides of the upper part of the middle frame are connected to the fixed plates, and multiple nozzles are connected to the fixed plates.

[0016] Beneficial effects of the present invention: 1. The present invention pushes the vertical rail to move left and right on the guide block while the crank wheel rotates, so that the traction rope moves left and right, and the rope wheel supports and guides the traction rope. When the traction rope moves left and right, it drives the slider to move left and right, so that the slider squeezes the protrusion of the brush and the compression spring stretches, so that the brush approaches the crushing wheel. When the crushing wheel rotates, it contacts the brush, thereby achieving the effect of being able to clean the crushing wheel in time during the crushing process to avoid affecting the crushing efficiency and equipment life.

[0017] 2. The present invention rotates the crank wheel on the left side, thereby driving the convex column to rotate, so that the convex column pushes the rail rod and the cross bridge to move up and down, driving the rolling block to move up and down, so that the rolling block cooperates with the screen to roll the coal on the screen, thereby achieving the effect of pre-rolling and crushing the coal, improving the coal crushing efficiency, and reducing the wear of the crushing wheel.

[0018] 3. The present invention promotes the hook plate to rotate and separate from the inclined frame while the crushing wheel rotates. At this time, the cross bar rotates and the torsion spring is deformed. When the crushing wheel separates from the hook plate, the torsion spring recovers, causing the hook plate to rotate and reset to hit the inclined frame, thereby achieving the effect of vibrating the inclined frame and preventing coal from being blocked on the screen.

[0019] 4. When the present invention crushes the coal, according to the crushing demand, the temperature controller is started to cool or heat the temperature control tube to adjust the internal temperature of the middle frame, so as to achieve the effect of crushing the coal under appropriate temperature conditions and improving the crushing efficiency.

DETAILED DESCRIPTION

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] A coal crushing device for mining which is easy to clean, such as Figure 1-Figure 8 As shown, it includes a base 1, a middle frame 2, a top frame 3, an inclined frame 4, a screen 40, a crushing mechanism 5 and a cleaning mechanism 7. The middle frame 2 is connected to the upper part of the base 1, and a material receiving box is provided on the lower side of the base 1 for easy material receiving. The top frame 3 is connected to the upper side of the middle frame 2, and the inclined frame 4 is connected inside the top frame 3. The screen 40 is connected to the lower side of the inclined frame 4. The middle frame 2 is provided with a crushing mechanism 5, and the middle frame 2 is also provided with a cleaning mechanism 7.

[0032] like Figure 1 and Figure 3 As shown, the crushing mechanism 5 includes a frame 51, a motor 52, a crank wheel 53, a gear ring 54 and a crushing wheel 55. The frame 51 is connected to the front side of the lower part of the middle frame 2, and the motor 52 is connected to the upper side of the frame 51. The front sides of the left and right parts of the middle frame 2 are both rotatably connected to the crank wheels 53, and the rear sides of the left and right parts of the middle frame 2 are also rotatably connected to the crank wheels 53. The output shaft of the motor 52 is connected to the adjacent crank wheels 53, and the outer sides of the crank wheels 53 are connected to the gear rings 54. The two adjacent gear rings 54 are meshed with each other. The left and right parts of the middle frame 2 are both rotatably connected to the crushing wheels 55, and the crank wheels 53 are connected to the adjacent crushing wheels 55.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the cleaning mechanism 7 includes a vertical rail 71, a traction rope 72, a pulley 73, a slider 74, a brush 75, a compression spring 76 and a guide block 77. The crank wheel 53 is movably connected to the vertical rail 71, and two upper and lower traction ropes 72 are connected between two vertically adjacent vertical rails 71. The front and rear parts of the middle frame 2 are rotatably connected to four pulleys 73, and the traction ropes 72 are in contact with adjacent pulleys 73. A slider 74 is connected between two adjacent traction ropes 72, and the sliders 74 are slidably connected to the middle frame 2. The inner sides of the left and right parts of the middle frame 2 are slidably connected to brushes 75, and bristles are provided on the brushes 75 to facilitate cleaning the crushing wheel 55.

The front and rear parts of the middle frame 2 are connected to left and right guide blocks 77, and the vertical rails 71 are slidably connected to adjacent guide blocks 77.

[0034] When using the present invention, first place the base 1 in the coal crushing area, then pour the coal into the top frame 3, so that the coal falls into the middle frame 2 through the screen 40 on the inclined frame 4, and then start the motor 52 on the frame 51 to drive the crank wheel 53 to rotate, the gear ring 54 engages and moves, so that the crushing wheel 55 rotates to crush the coal, and the crushed coal falls into the receiving box. While the crank wheel 53 rotates, it pushes the vertical rail 71 to move left and right on the guide block 77, so that the traction rope 72 moves left and right, and the rope wheel 73 supports and guides the traction rope 72. When the traction rope 72 moves left and right, it drives the slider 74 to move left and right, so that the slider 74 squeezes the protrusion of the plate brush 75, and the compression spring 76 stretches, so that the plate brush 75 is close to the crushing wheel 55. When the crushing wheel 55 rotates, it contacts the plate brush 75, thereby playing a role in timely cleaning the crushing wheel 55 during the crushing process to avoid affecting the crushing efficiency and the life of the equipment. After the slider 74 is separated from the protrusion of the plate brush 75, the compression spring 76 rebounds, so that the plate brush 75 is reset.

[0035] like Figure 1 and Figure 4 As shown, it also includes a crushing mechanism 6, which includes a boss 61, a rail 62, a cross bridge 63 and a crushing block 64.

The lower side of the cross bridge 63 is connected to the crushing block 64, and the lower part of the crushing block 64 is toothed to facilitate crushing of coal blocks. The crushing block 64 is located on the upper side of the screen 40.

[0036] The crushing mechanism 6 of the device can be used to crush coal. When the crank wheel 53 on the left side rotates, the boss 61 is driven to rotate, so that the boss 61 pushes the rail rod 62 and the cross bridge 63 to move up and down, and drives the crushing block 64 to move up and down, so that the crushing block 64 cooperates with the screen 40 to crush the coal on the screen 40, thereby achieving the effect of crushing the coal in advance, improving the coal crushing efficiency, and reducing the wear of the crushing wheel 55.

[0037] like Figure 1 and Figure 7 As shown, it also includes a knocking mechanism 8, which includes a cross bar 81, a torsion spring 82, a hook plate 83 and a handle 84.

The hook plates 83 are in contact with the diagonal frame 4, and the front sides of the cross bars 81 are connected to handles 84.

[0038] The knocking mechanism 8 of the device can be used to knock the inclined frame 4. While the crushing wheel 55 rotates, it pushes the hook plate 83 to rotate and separate from the inclined frame 4. At this time, the cross bar 81 rotates and the torsion spring 82 is deformed. When the crushing wheel 55 separates from the hook plate 83, the torsion spring 82 recovers, causing the hook plate 83 to rotate and reset to hit the inclined frame 4, thereby causing the inclined frame 4 to vibrate and preventing coal from being blocked on the screen 40. After the crushing wheel 55 stops running, the cross bar 81 can be rotated by the handle 84.

[0039] like Figure 1 and Figure 8 As shown, a temperature control mechanism 9 is also included, and the temperature control mechanism 9 includes a temperature controller 91 and a temperature control tube 92. The left and right parts of the middle frame 2 are connected to two front and rear temperature controllers 91, and five temperature control tubes 92 are connected between two vertically adjacent temperature controllers 91. The temperature control tubes 92 are located on the outside of the inclined frame 4.

[0040] By using the temperature control mechanism 9 of the device, the temperature inside the middle frame 2 can be controlled. When the coal is crushed, the temperature controller 91 is started according to the crushing requirements to cool or heat the temperature control tube 92 to adjust the internal temperature of the middle frame 2, thereby achieving the effect of crushing the coal under appropriate temperature conditions and improving the crushing efficiency.

[0041] like Figure 1 and Figure 8 As shown, a flushing mechanism 10 is also included, and the flushing mechanism 10 includes a fixed plate 101 and a nozzle 102. The fixed plates 101 are connected to the left and right sides of the upper part of the middle frame 2. Five nozzles 102 are connected to the fixed plates 101, and the nozzles 102 all pass through the middle frame 2.

[0042] The flushing mechanism 10 of the device can be used to flush the crushing wheel 55. After the crushing wheel 55 stops running, the water pipe is connected to the nozzle 102, and the nozzle 102 is aimed at the crushing wheel 55 to spray water, thereby flushing the crushing wheel 55 and avoiding affecting the subsequent crushing efficiency.
