[0002] Coal mining and sorting refers to the extraction and sorting of coal in a coal mine through steps such as extraction and sorting. This involves miners extracting coal underground or in the open pit, and then sorting and processing the extracted coal to meet different uses and market demands:

[0003] Traditional sorting technology may not be able to achieve accurate classification of coal, resulting in some mixed materials entering the final product, and some sorting tasks still require manual intervention, which increases labor costs and labor intensity. Therefore, there is an urgent need for a coal sorting machine for coal mining.

[0004] It should be noted that the above content falls within the technical cognition of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a coal sorting machine for coal mining.

[0006] To achieve the above-mentioned purpose, the present invention proposes a coal sorting machine for coal mining, comprising a coal receiving cylinder:

[0007] Both sides of the outer wall of the coal receiving cylinder are fixedly connected to the two sides of the sorting plate through a vibration structure, the inner wall of the sorting plate is fixedly connected to the outer wall of the middle seat through four support frames, and a screen is provided between each two adjacent support frames. A driving motor is fixedly provided in the middle position of the top end of the middle seat, and the output end of the driving motor is fixedly connected to one side of the rotary screen plate through a connecting frame. An open discharge channel is provided at one end of the sorting plate.

[0008] In one example, the bottom of the open feed channel is tilted, and the tilt angle is degrees.

[0009] In one example, the apertures of the four screens increase progressively.

[0010] In one example, the vibration structure includes a first support seat fixedly arranged on both sides of the outer wall of the coal receiving cylinder, and slide rods are fixed on both sides of the top of the two first support seats, and the two slide rods are connected with the corresponding second support seats through the insertion, and a mounting frame is fixed at the bottom end of the second support seat, and a dual-output shaft servo motor is fixed inside the mounting frame, and a turntable is fixed at both output ends of the dual-output shaft servo motor, and a counterweight is fixed on the outer walls of the two turntables.

[0011] In one example, a limiting plate is fixedly provided on the top of each of the two sliding rods, and a spring is sleeved on the top and bottom of the outer wall of each of the two sliding rods.

[0012] In one example, the screens inside each group of the sorting trays correspond to the receiving grids inside the coal receiving cylinder.
