Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a coal mining transfer device with an anti-blocking structure. Background Technology

[0002] Coal mining involves extracting coal from underground or open-pit mines. Transfer devices are used in coal mining, and these devices are coal transfer and conveying equipment that can transfer coal over short distances, smoothly transporting raw coal to main transport equipment such as belt conveyors.

[0003] Currently, the transfer device still has some shortcomings, such as the transfer machine's feed inlet being prone to blockage when the amount of coal is large.

[0004] To overcome the problem of blockage in transfer conveyors, a prior art Chinese patent (publication number: CN212892223U) discloses a transfer conveyor feed inlet with a function to prevent blockage by large pieces of coal gangue. By setting up a transfer conveyor feed inlet with the function of preventing blockage by large pieces of coal gangue, the coal passage height and coal passage volume are further increased, the raw coal output is increased, and the blockage of the feed inlet by large pieces of coal gangue is prevented. The design and processing of the heightening plate from the transfer conveyor feed inlet to the crusher section can effectively reduce the coal overflow at the feed inlet, which can reduce the manual input of coal cleaning personnel and reduce the workload of front-end workers. By setting the auxiliary tightening device at the top left and right ends of the frame, the connecting rod can be rotated by rotating the handle to rotate on the base, so that the connecting rod drives the sliding rod to slide on the sliding seat, thereby adjusting the tightening according to the different distances between the heightening plate and the external mounting plate, and avoiding frame shaking during the feeding process.

[0005] Most of the existing technologies mentioned above improve the overall structure by dividing the coal entering the transfer machine through baffles to prevent large amounts of coal from clogging. However, although dividing the feed inlet can separate the coal from each other, clogging is still possible. Therefore, the existing structure needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a coal mine transfer device with an anti-blocking structure to solve the problem of potential blockage in coal mine transfer devices mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coal mine excavation and transfer device with an anti-blocking structure, including a frame door, wherein a fixing hole is provided on the side of the frame door.

[0008] The frame door is internally connected to a toothed plate, which is symmetrically distributed about the center of the frame door. Gears are meshed on the sides of the toothed plate, and a rotating mechanism to prevent the device from getting stuck is provided inside the frame door.

[0009] Furthermore, the rotating mechanism includes symmetrical sliding grooves opened on the inner side of the frame door, a guide block is slidably connected inside the sliding groove, and a rotating rod is fixed at the bottom of the gear, and the rotating rod rotates through the sliding groove and the guide block.

[0010] Furthermore, a rotating rod is fixed to the end of the gear shaft, and a threaded rod is threadedly connected to the side of the guide block near the gear shaft.

[0011] Furthermore, the threaded rod rotates inside the frame door, and the end of the threaded rod is connected to the output end of the motor, and the motor is installed on the left side of the frame door.

[0012] Furthermore, four sets of fixing blocks are symmetrically fixed on the side of the fixing hole, and an external block is slidably connected through the fixing block. The fixing block is equipped with a replacement mechanism to reduce the wear and tear of the transfer device.

[0013] Furthermore, the replacement mechanism includes symmetrical telescopic grooves that penetrate through the inside of the fixed block, with the telescopic block slidably connected inside the telescopic groove, and a pull block fixed to the side of the telescopic block, the pull block sliding through the inside of the telescopic groove.

[0014] Furthermore, a spring is connected between the telescopic block and the telescopic groove, and the telescopic block and the slot form an engaging connection. The slot is symmetrically opened on the side of the outer block.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This coal mining and transfer device, equipped with an anti-blocking structure, prevents coal blocks from clogging the inside of the frame door. The motor is activated, and its output drives a threaded rod to rotate. This causes the guide block to slide, moving a rotating rod and gears. The gears mesh with the toothed plate, rotating and driving the rotating rod to rotate, which in turn causes the outer block to break up the blocked coal, allowing it to fall to the conveying position. The rotating rod also moves with the guide block, improving the breaking-up effect and effectively preventing the frame door from getting stuck.

[0016] Furthermore, the meshing of the gear and the toothed plate enables the rotation of the rotating rod, which can move along with the guide block. The rotating rod achieves both movement and rotation, thus effectively breaking up the blocked coal blocks. Furthermore, the telescopic block, with its spring extension and retraction, can improve the efficiency of replacing the outer block, and after replacement, it can ensure the outer block's effect of breaking up coal lumps.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Example 1: As Figures 1-4 The present invention provides the following technical solution: In order to solve the problem of possible blockage in coal mine transfer devices, a rotating mechanism is disclosed: a coal mine transfer device with an anti-blocking structure, including a frame door 1, and a fixing hole 2 is provided on the side of the frame door 1.

[0021] A toothed plate 101 is connected inside the frame door 1. The toothed plates 101 are symmetrically distributed about the center of the frame door 1. A gear 102 is meshed with the side of the toothed plate 101. A rotating mechanism to prevent the device from getting stuck is provided inside the frame door 1. The rotating mechanism includes sliding grooves 103 symmetrically opened on the inside of the frame door 1. A guide block 104 is slidably connected inside the sliding groove 103. A rotating rod is fixed to the bottom of the gear 102 and rotates through the sliding groove 103 and the guide block 104. A rotating rod 105 is fixed to the end of the rotating rod of the gear 102. A threaded rod 106 is threadedly connected to the side of the guide block 104 near the rotating rod of the gear 102. The threaded rod 106 rotates inside the frame door 1, and the end of the threaded rod 106 is connected to the output end of the motor. The motor is installed on the left side of the frame door 1.

[0022] When the coal mine transfer device is in use, the frame gate 1 faces the coal mine. Other components of the equipment can excavate the coal, which then passes through the frame gate 1 onto the conveyor. To prevent coal from clogging the inside of the frame gate 1, a motor can be started. When the motor starts, its output end drives the threaded rod 106 to rotate. The rotation of the threaded rod 106 drives the guide block 104 to slide threadedly. This threaded sliding of the guide block 104 drives the inner rotating rod to move. The movement of the rotating rod drives the gear 102 to move. The gear 102 can mesh and rotate on the side of the toothed plate 101. When the gear 102 meshes and rotates, it can drive the rotating rod 105 to rotate through the rotating rod. When the rotating rod 105 rotates, it can drive the outer block 201 to rotate. The outer block 201 can break up the coal blocks blocking the inside of the frame door 1. After being broken up, the coal blocks can fall onto the conveying position of the transfer device. While rotating, the rotating rod 105 will move along with the guide block 104, thereby improving the effect of the outer block 201 in breaking up the coal blocks and preventing the frame door 1 of the transfer device from getting stuck.

[0023] Example 2: Figures 1-3 , Figure 5 and Figure 6 The present invention provides the following technical solution: a replacement mechanism is disclosed. Fixing blocks 202 are symmetrically fixed on the side of fixing hole 2, and four sets of fixing blocks 202 are symmetrically arranged on the side of fixing hole 2. An external block 201 is slidably connected through the inside of fixing block 202. A replacement mechanism to reduce the wear and tear of the transfer device is provided inside fixing block 202. The replacement mechanism includes a telescopic groove 203 symmetrically opened through the inside of fixing block 202. A telescopic block 204 is slidably connected inside the telescopic groove 203. A pull block 205 is fixed on the side of telescopic block 204. The pull block 205 slides through the telescopic groove 203. A spring is connected between telescopic block 204 and telescopic groove 203. The telescopic block 204 and the slot 206 form a snap-fit ​​connection. The slot 206 is symmetrically opened on the side of the external block 201.

[0024] After prolonged use, the outer block 201 will wear out. Pulling the pull block 205 will move the telescopic block 204. When the telescopic block 204 moves, it can slide inside the telescopic groove 203 and the slot 206. When the telescopic block 204 slides, it can compress the spring. When the telescopic block 204 is squeezed out of the slot 206, it can pull the outer block 201. When the outer block 201 is pulled, it can slide inside the fixed block 202. After the outer block 201 slides out of the fixed block 202, it can be disassembled and replaced. After the outer block 201 is replaced, the effect of breaking up coal blocks can be guaranteed, which can effectively prevent the frame door 1 from being blocked by coal blocks. At the same time, the replacement of the outer block 201 can also reduce the replacement cost of worn parts of the device.
