Description

Technical Field

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

[0002] During coal mining, the extracted raw coal needs to be crushed and screened to break large coal particles to a size that meets the requirements for transportation or use, while separating small finished coal particles. This process requires extremely high continuity and efficiency.

[0003] Currently, traditional coal mining crushing devices are mostly single screening-crushing processes without a material backflow structure. When the crusher gets clogged, it needs to be stopped for cleaning, which leads to coal accumulation and interruption of operations. In view of this, we propose a coal mining crushing device. Utility Model Content

[0012] This utility model provides a coal mining and crushing device. It has the following beneficial effects: (1) The material distribution component of the coal mining and crushing device can separate large particles of coal to be crushed from small particles of finished coal through the vibrating screen plate. Large particles of coal enter the crusher for crushing through the receiving ring frame, and small particles of coal are collected through the discharge inclined plate. When the crusher is blocked, the switching component can drive the material distribution component to rotate, so that the large particles of coal are switched to the conveyor belt device to return to the mine.

[0020] In this utility model, the inner wall of the fixed block 46 is threaded with a limiting pin 47, the driving gear 44 and the internal gear ring 45 mesh with each other, the sliding ring seat 42 is provided with a limiting groove, the limiting groove is an annular groove, the limiting pin 47 is a stepped bar design and is provided with partial threads to facilitate threaded connection with the fixed block 46, the end of the limiting pin 47 away from the thread can slide into the limiting groove, through the cooperation of the fixed block 46 and the limiting pin 47, the sliding ring seat 42 is conveniently limited to ensure that the sliding ring seat 42 can rotate stably, the motor 43 is started, the motor 43 drives the driving gear 44 to rotate, and the internal gear ring 45 drives the sliding ring seat 42 to rotate, and the rotation of the synchronous base plate 51 drives the material distribution inclined seat 52 to rotate synchronously.

[0021] Furthermore, a material distribution component 5 is provided on the support base 1. The material distribution component 5 includes a synchronous base plate 51. The bottom of the synchronous base plate 51 is fixedly connected to the top of the sliding ring seat 42, and the top of the synchronous base plate 51 is fixedly connected to the material distribution inclined seat 52.

[0022] Furthermore, a guide slide rod 53 is fixedly connected to the top of the material distribution inclined seat 52, and a screening plate 54 is slidably connected to the outer wall of the guide slide rod 53. The material distribution inclined seat 52 and the screening plate 54 are elastically connected by a spring, and a vibrator 55 is fixedly connected to the bottom of the screening plate 54.

[0023] Furthermore, a discharge chute 56 is provided on the material distribution inclined seat 52, and a discharge inclined plate 57 is fixedly connected to the bottom of the material distribution inclined seat 52. The discharge inclined plate 57 is located below the discharge chute 56. The discharge inclined plate 57 assists in guiding the coal falling from the discharge chute 56, so that it leaves the material distribution inclined seat 52 and enters the conveyor belt device 9 or the recycling frame 10 (depending on the position of the discharge inclined plate 57).

[0024] Furthermore, a support frame 6 is fixedly connected to the top of the receiving ring frame 2, and a discharge hopper 3 is detachably connected to the support frame 6. The discharge hopper 3 is installed by the support frame 6 and screws.

[0025] Furthermore, a crusher 7, a first conveyor belt device 8, a second conveyor belt device 9, and a recycling frame 10 are arranged circumferentially below the receiving ring frame 2, and the crusher 7, the first conveyor belt device 8, the second conveyor belt device 9, and the recycling frame 10 are respectively located on the four outer sides of the support base 1.

[0026] It should be noted that the above electrical components are all existing technology products.

[0027] In use, the coal is transported to the discharge hopper 3 by the conveyor belt assembly on the mine. The coal falls onto the distribution assembly 5 through the discharge hopper 3. The vibrator 55 is activated to move the screening plate 54 up and down along the guide slide bar 53, so that the coal can fall into the receiving ring frame 2 along the screening plate 54. Then it falls into the crusher 7 from the discharge port and is crushed by the crusher 7. At the same time, the small coal particles screened pass through the screening plate 54 and fall onto the distribution inclined seat 52. After passing through the discharge chute 56, they are guided by the discharge inclined plate 57 to the conveyor belt device 9, completing the collection of the small coal particles after screening. When a blockage occurs at crusher 7, the conveyor belt assembly on the mine is not easy to stop. In order to avoid coal accumulation, the shifting assembly 4 is activated, which drives the motor 43 to rotate the drive gear 44. The internal gear ring 45 drives the sliding ring seat 42 to rotate. The rotation of the synchronous base plate 51 drives the material distribution inclined seat 52 to rotate synchronously, causing the screening plate 54 to rotate 90 degrees. At this time, the coal falling from the screening plate 54 falls into the receiving ring frame 2. However, the screened coal now leaves the receiving ring frame 2 from the discharge port above the conveyor belt device 8 and is transported back to the mine by the conveyor belt device 8, which facilitates the crushing work again and avoids coal blockage. In addition, the rotation of the synchronous bottom plate 51 will also cause the discharge inclined plate 57 to rotate synchronously, causing the screened small coal ore to fall into the recycling frame 10, so that the screened coal ore can still be collected, thus improving the adaptability of the device.
