Description

Technical Field

[0001] The utility model relates to the technical field of coal processing, in particular to a vibrating screen used for coal processing. Background Art

[0002] Coal is a solid combustible mineral that was gradually formed when ancient plants were buried underground and underwent complex biochemical and physicochemical changes.

[0003] Coal needs to be processed before use. During the processing of coal, it is often necessary to screen the coal. In this case, a vibrating screen is generally used. The existing vibrating screen generally applies a small vibration force to the screen to make the screen vibrate with a small amplitude for screening. However, some coals are large in shape. When they fall onto the screen during screening, the screen is easily damaged, thereby affecting the subsequent screening of the coal. Therefore, a vibrating screen for coal processing is proposed.

A sieve plate 10 is fixedly installed on the surface, and the sieve plate 10 is inclined. There are two groups of mounting plates 4. The inclined setting of the sieve plate 10 facilitates the movement of coal and avoids coal clogging in the processing box 1. A buffer assembly is arranged inside the processing box 1. The buffer assembly includes an electric push rod 11 fixedly installed inside the processing box 1. A push block 12 is fixedly installed on the output end of the electric push rod 11. A buffer inclined plate 13 is hingedly installed inside the processing box 1, and the bottom surface of the buffer inclined plate 13 is fitted with the push block 12. Through the setting of the buffer assembly, the output end of the electric push rod 11 drives the push block 12 to move and pushes the buffer inclined plate 13, so that the inclination angle of the buffer inclined plate 13 changes to avoid clogging. 1 is provided with a vibration assembly inside, and the vibration assembly includes a driving motor 14 fixedly mounted on the surface of the processing box 1, and the output end of the driving motor 14 is fixedly mounted with a rotating shaft 15, and the surface of the rotating shaft 15 is fixedly mounted with a cam 16, and the number of the cams 16 is two groups. Through the setting of the vibration assembly, the output end of the driving motor 14 rotates, driving the rotating shaft 15 to rotate, so that the cam 16 rotates, and then the screen plate 10 vibrates, so that the screening effect of the coal is better, and a collecting box 17 is slidably installed inside the processing box 1, and a supporting leg 18 is fixedly mounted on the bottom surface of the processing box 1, and an anti-skid pad is fixedly mounted on the bottom surface of the supporting leg 18. Through the setting of the anti-skid pad, the friction between the supporting leg 18 and the ground is increased. The rubbing area makes the device more stable when in use. The setting of the buffer inclined plate 13 can play a certain buffering role, which can prevent coal from falling directly from a high place onto the screen plate 10, and reduce the damage caused by the coal to the screen plate 10. The setting of the vibration component makes the cam 16 rotate, and the bottom surface of the screen plate 10 can be knocked as the cam 16 rotates, and the bottom of the movable block 7 is fixedly connected to the spring 6. When the cam 16 knocks the screen plate 10, the screen plate 10 will vibrate up and down, so that the screen plate 10 can screen the coal. The screened fragments pass through the sieve holes and fall into the collecting box 17. The larger coal is discharged from the processing box 1 through the discharge pipe 3, and the screening of the coal can be completed.

[0020] During use: the coal to be screened is added into the processing box 1 through the feed hopper 2, and the coal falls onto the top of the buffer inclined plate 13, which can play a certain buffering role, and can prevent the coal from falling directly from a high place onto the screen plate 10, thereby reducing the damage caused by the coal to the screen plate 10. The coal falls from the buffer inclined plate 13 onto the screen plate 10, and the drive motor 14 is started. The output end of the drive motor 14 rotates, driving the rotating shaft 15 to rotate, so that the cam 16 rotates. As the cam 16 rotates, the bottom surface of the screen plate 10 can be knocked, and the bottom of the movable block 7 is fixedly connected to the spring 6. When the cam 16 knocks the screen plate 10, the screen plate 10 will vibrate up and down, thereby facilitating the screen plate 10 to screen the coal, and the screened fragments pass through the sieve holes and fall into the collecting box 17. The larger coal is discharged from the processing box 1 through the discharge pipe 3, and the screening of the coal can be completed.
