[0004] The above mechanism filters the crushed coal through the filtering mechanism and transports and crushes it multiple times. However, in actual use, part of the coal will be stuck on the screen when screening the coal, affecting the screening efficiency and also affecting the efficiency of coal discharge. Utility Model Content

[0005] The utility model aims to provide a crusher for intelligent coal mining to solve the problem in the background technology that part of the coal is stuck on the screen during coal screening, which affects the screening efficiency and also affects the coal discharge.

[0006] To achieve the above object, the utility model provides the following technical solution: a crusher for intelligent mining of coal mines, comprising a crushing box, a feed port is provided at the top of the crushing box, a discharge port is provided at the bottom of the crushing box, and a crushing roller is rotatably connected to the upper end between the two ends of the crushing box;

[0007] A first drive motor is fixedly connected to one end of the crushing box, and an output end of the first drive motor is connected to a crushing roller. A screening mechanism for processing ore is arranged inside the crushing box below the crushing roller. The screening mechanism comprises a screen plate, and the screen plate is rotatably connected to the inside of the crushing box. A torsion spring is hinged on one side of the bottom end of the screen plate.

[0008] A second drive motor is fixedly connected to the middle position of the bottom end of the discharge port, and the output end of the second drive motor extends to the top of the discharge port and is fixedly connected to a cleaning mechanism for cleaning the discharge port.

[0009] Furthermore, the output end of the first driving motor is rotatably connected to a cam via a pulley, and both ends of the screen plate are fixedly connected to limit rods, one end of the limit rod passes through and extends to the outside of the crushing box.

[0010] Furthermore, the cam is arranged on one side of the limiting rod, and the cam is arranged outside the crushing box.

[0011] Furthermore, a crushing adjustment mechanism is provided at the output end of the first drive motor, and the crushing adjustment mechanism includes a driving gear, and the driving gear is fixedly connected to the output end of the first drive motor, and racks are slidably connected at both ends of the outside of the crushing box, and the driving gear and the rack are meshed with each other, and the rack is fixedly connected to the extrusion plate.

[0012] Furthermore, slide rails are provided at the upper ends of both ends of the crushing box, and sliders matching the slide rails are fixedly connected to both ends of the extrusion plate. The crushing box and the extrusion plate are slidably connected through the sliders and the slide rails to form a sliding mechanism.

[0013] Furthermore, the cleaning mechanism includes a fixed box, and the fixed box is fixedly connected to both sides of the second drive motor. A cleaning brush is fixedly connected to the interior of the fixed box through a connecting spring, and the bottom end of the cleaning brush fits with the top end of the discharge port.

[0014] Furthermore, a feed trough is rotatably connected inside the feed port, and the top of the feed trough passes through and extends to the top of the feed port.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. After the crushing process, the output end of the first driving motor drives the cam to rotate through the pulley. When the cam rotates, it will continuously push the extrusion limit rod, so that the height of the limit rod changes, and then the screen plate vibrates due to the continuous pushing, and the coal remaining on the surface of the screen plate is screened to avoid excessive coal blocking the screen plate and affecting the screening efficiency of the coal;

[0017] Furthermore, the elastic force of the torsion spring can assist the screen plate to quickly reset its angle after being squeezed. The screen plate vibrates due to the elastic force of the torsion spring, and the screen plate continuously screens the materials accumulated above due to the vibration, so that the coal mine can achieve separation of different particle sizes;

[0018] Furthermore, the continuously rotating feed chute can make the weight of the coal entering the crushing box close each time, avoiding the situation where too much material enters at one time and causes the feed port to be blocked. The ore is evenly fed into the crushing box, which is convenient for better processing and crushing.

[0019] 2. Some ore will accumulate above the discharge port. The output end of the second drive motor will drive the fixed box to rotate, and the cleaning brush will contact the top of the discharge port, so as to discharge the material accumulated on the surface of the discharge port, avoiding the accumulation of material inside the device and affecting the subsequent material discharge;

[0020] Furthermore, the output end of the first drive motor will drive the active gear to rotate during the rotation process, and the rotation of the active gear will mesh with the rack, so that the rack drives the extrusion plate to move left and right. Since the left and right movement of the extrusion plate will adjust the distance between the crushing roller and the extrusion plate, when the coal falls between the crushing roller and the extrusion plate, due to the different distances between them, coal of different sizes can fall and be squeezed, thereby achieving better crushing processing.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 6 The technical solution shown is to solve the problem that part of the coal is stuck on the screen when screening the coal, which affects the screening efficiency and also affects the coal discharge: the coal mine intelligent mining adopts a crusher, and discloses a screening mechanism, including a crushing box 1, a feed port 2 is provided at the top of the crushing box 1, a discharge port 3 is provided at the bottom of the crushing box 1, a crushing roller 8 is rotatably connected to the upper end between the two ends of the crushing box 1, and a first drive motor 5 is fixedly connected to one end of the crushing box 1, and the output end of the first drive motor 5 is connected to the crushing roller 8 A screening mechanism for processing ore is arranged inside the crushing box 1 below the crushing roller 8, and the screening mechanism includes a screen plate 12, and the screen plate 12 is rotatably connected to the inside of the crushing box 1, a torsion spring 13 is hinged on one side of the bottom end of the screen plate 12, and the output end of the first drive motor 5 is rotatably connected to a cam 15 through a pulley, and both ends of the screen plate 12 are fixedly connected to a limit rod 14, one end of the limit rod 14 passes through and extends to the outside of the crushing box 1, the cam 15 is arranged on one side of the limit rod 14, and the cam 15 is arranged outside the crushing box 1.

[0032] In this example, the coal is fed into the crushing box 1 by the feed port 2 and the feed chute 4. The continuously rotating feed chute 4 can make the weight of the coal entering the crushing box 1 close each time, so as to avoid the situation that too much material enters at one time and causes the feed port 2 to be blocked. Then, the output end of the first drive motor 5 is used to drive the crushing roller 8 and the extrusion plate 9 to rotate and move, thereby realizing the crushing of the coal.

[0033] After the crushing process, the output end of the first drive motor 5 drives the cam 15 to rotate through the pulley. When the cam 15 rotates, it will continuously push and squeeze the limit rod 14, so that the height of the limit rod 14 changes. When the height of the limit rod 14 changes, the angle of the torsion spring 13 will also change, and then the screen plate 12 will vibrate due to the continuous pushing, and the coal remaining on the surface of the screen plate 12 will be screened to avoid too much coal blocking the screen plate 12 and affecting the screening efficiency of the coal.

[0034] Embodiment 2:

[0035] like Figure 1 , Figure 3 , Figure 6 and Figure 7 The technical solution shown is to solve the problem of accumulation and residue when the crusher discharges materials: the coal mine intelligent mining crusher discloses a cleaning mechanism, a second drive motor 16 is fixedly connected to the middle position of the bottom end of the discharge port 3, and the output end of the second drive motor 16 extends to the top of the discharge port 3 and is fixedly connected to a cleaning mechanism for cleaning the discharge port 3, the cleaning mechanism includes a fixed box 17, and the fixed box 17 is fixedly connected to both sides of the second drive motor 16, the interior of the fixed box 17 is fixedly connected to a cleaning brush 19 through a connecting spring 18, and the bottom end of the cleaning brush 19 is in contact with the top of the discharge port 3, the feed port 2 is rotatably connected to the feed trough 4, and the top of the feed trough 4 passes through and extends to the top of the feed port 2.

[0036] In this example, after the coal mine is screened, unqualified ore is discharged from the crushing box 1 through the slot at one end of the crushing box 1 and subjected to secondary crushing, while qualified ore is discharged from the device through the discharge port 3;

[0037] Part of the ore will accumulate above the discharge port 3, and the fixed box 17 will be driven to rotate through the output end of the second drive motor 16. When the fixed box 17 rotates, the cleaning brush 19 inside the fixed box 17 will contact the top of the discharge port 3, thereby discharging the material accumulated on the surface of the discharge port 3, avoiding the accumulation of material inside the device and affecting the subsequent material discharge.

[0038] Embodiment three:

[0039] like Figure 1 , Figure 2 , Figure 5 , and the technical solution shown in 6 is to solve the problem that ores of different sizes enter the device and are inconvenient to be crushed when crushing coal mines: the coal mine intelligent mining crusher discloses a crushing adjustment mechanism, and the output end of the first drive motor 5 is provided with a crushing adjustment mechanism, and the crushing adjustment mechanism includes a driving gear 6, and the driving gear 6 is fixedly connected to the output end of the first drive motor 5, and both ends of the outside of the crushing box 1 are slidably connected with a rack 7, and the driving gear 6 and the rack 7 are meshed with each other, and the rack 7 is fixedly connected to the extrusion plate 9, and the upper ends of the two ends inside the crushing box 1 are provided with slide rails 11, and both ends of the extrusion plate 9 are fixedly connected with sliders 10 matching the slide rails 11, and the crushing box 1 and the extrusion plate 9 are slidably connected through the slider 10 and the slide rail 11 to form a sliding mechanism.

[0040] In this example, the output end of the first drive motor 5 drives the driving gear 6 to rotate during the rotation process, and the rotation of the driving gear 6 is meshed with the rack 7, so that the rack 7 drives the extrusion plate 9 to move left and right. Since the left and right movement of the extrusion plate 9 can adjust the distance between the crushing roller 8 and the extrusion plate 9, when the coal falls between the crushing roller 8 and the extrusion plate 9, due to the different distances between them, coal of different sizes can fall and be squeezed, thereby achieving better crushing processing.
