Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment technology, specifically a coal mining continuous mining crushing device. Background Technology

[0002] In continuous coal mining, the continuous mining machine automatically loads coal, and an intermediate conveyor transports the coal to a shuttle car. The shuttle car then transports the loaded coal to a crusher for crushing. After crushing, the coal is transferred to a roadway conveyor for transport to the main roadway conveyor. The crusher is located at one end of the roadway conveyor to crush coal blocks before transport, reducing excessively large blocks and ensuring that the smaller blocks are more suitable for subsequent processing and transportation.

[0003] The existing patent publication number CN212915812U discloses an underground coal block crusher for coal mining, which includes a crushing box. The upper surface of the crushing box is fixedly connected to a feed hopper. The inner sidewalls of the feed hopper are all fixedly hinged with buffer plates by pins. The left and right sides of the feed hopper are fixedly connected to two fixed frames. The inner wall of the crushing box is rotatably connected to a crushing roller by bearings. Both sides of the crushing roller are provided with crushing plates. After the crushing roller crushes the coal block, the crushing roller further crushes the coal block.

[0004] The aforementioned crusher can crush underground modules, but it uses direct feeding. When large or irregularly shaped coal pieces are directly fed into the crusher, it may cause blockage or overload, thus reducing crushing efficiency. Furthermore, some smaller coal particles are over-crushed, which can easily generate excessive dust during subsequent transportation. To address these issues, a coal mine continuous mining crushing device is proposed. Utility Model Content

[0012] In one alternative: the drive component a includes a motor mounted on one side of the feeding body and a drive wheel mounted on the power output end of the motor. A driven wheel is mounted on the end of a set of transmission shafts located near the motor. The driven wheel is connected to the drive wheel via a transmission belt. Adjacent sets of transmission shafts are connected via a synchronization component.

[0013] In one alternative: the synchronizing element includes synchronizing pulleys mounted on a drive shaft, and two adjacent sets of synchronizing pulleys are connected by a synchronous belt drive.

[0014] In one alternative: both ends of the toothed crushing roller are connected to mounting shafts, which are rotatably connected to the crushing body.

[0015] In one alternative: the drive component b includes a drive device disposed on one side of the crushing body for driving one set of mounting shafts to rotate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, coal blocks to be crushed are poured into the top of the feed hopper. Under the rotation of multiple spiral feeding rollers, the coal blocks are conveyed. Some small coal blocks can fall through the gaps of the spiral feeding rollers into the guide hood and be discharged. Larger coal blocks are conveyed to the crushing body for crushing and output. The screened coal blocks are easier to crush, and the energy consumption of the crusher is reduced accordingly. This is conducive to energy conservation and environmental protection, reduces ineffective crushing and over-crushing, and improves the processing efficiency of the crusher.

[0018] In this invention, the material output from the guide shroud and the bottom of the crushing body can be sent to the same conveyor belt in the mine to be transported to the next target point. The crushing device can be set at the feed end of the corresponding conveyor belt for crushing. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4In this embodiment, a coal mine continuous mining crushing device includes a feeding mechanism 100, which includes a feeding body 101, a support frame 102 connected to the bottom of the feeding body 101, a guide hopper 103 installed on the inner wall of the feeding body 101, and a plurality of spiral feeding rollers 105 disposed at the bottom of the guide hopper 103. The spiral feeding rollers 105 are rotatably installed at the bottom of the feeding body 101. The bottom of the feeding body 101 is connected to a guide shroud 104. A driving component a is installed on the feeding body 101 to drive the plurality of spiral feeding rollers 105 to rotate. The device also includes a crushing mechanism 200, which includes a crushing body 201, a protective cover 202 connected to the top of the crushing body 201, and two sets of toothed crushing rollers 203 disposed inside the crushing body 201. A driving component b is provided on one side of the crushing body 201 to drive the toothed crushing rollers 203 to rotate.

[0029] Using the above scheme, the shuttle car transports the loaded coal to the device. The coal to be crushed can be poured in from the top of the guide hopper 103. Under the rotation of multiple spiral feeding rollers 105, the coal blocks are conveyed. Some small coal blocks can fall from the gaps of the spiral feeding rollers 105 into the guide hood 104 and be discharged. Large coal blocks are conveyed to the crushing body 201 for crushing and output. The materials output from the bottom of the guide hood 104 and the crushing body 201 can be sent to the same conveyor belt in the mine to be transported to the next target point.

[0030] like Figure 1 and Figure 3 As shown, the feed hopper 103 has a discharge port on the side near the crushing body 201.

The support seat 106 supports the stable rotation of the spiral feed roller 105. The coal blocks output from the discharge port can slide along the guide plate 107 into the crushing body 201.

[0031] Furthermore, several of the spiral feeding rollers 105 are arranged in parallel. Each spiral feeding roller 105 includes a conveying roller and a spiral auger installed on the outer wall of the conveying roller. The end of the conveying roller away from the crushing body 201 extends into the drive cavity of the feeding body 101 and is connected to the drive shaft 108. When the spiral feeding roller 105 rotates, it can agitate the coal blocks.

[0034] like Figure 2 As shown, both ends of the toothed crushing roller 203 are connected to mounting shafts, which are rotatably connected to the crushing body 201. Two sets of mounting shafts on one side extend to the outside of the crushing body 201 and are fixedly connected to gears 204. The two sets of gears 204 mesh. When one set of mounting shafts rotates, the other set of mounting shafts can be driven to rotate through the meshing transmission of the two sets of gears 204. The two sets of toothed crushing rollers 203 rotate relative to each other to perform crushing operations.

[0035] like Figure 2 As shown, the driving component b includes a driving device 205 disposed on one side of the crushing body 201 for driving one set of mounting shafts to rotate; the driving device 205 can be a combination of an existing electric motor and a reducer.
