Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen with a cleaning structure. Background Art

[0002] A vibrating screen operates by utilizing reciprocating vibrations generated by a vibrator. The vibrator's upper rotating weight produces planar gyratory vibrations on the screen surface, while the lower rotating weight produces conical gyratory vibrations. The combined effect produces complex gyratory vibrations on the screen surface. The vibration trajectory is a complex spatial curve. This curve projects horizontally as a circle and vertically as an ellipse. Adjusting the excitation force of the upper and lower rotating weights changes the amplitude. Adjusting the spatial phase angle of the upper and lower weights alters the shape of the screen surface's motion trajectory, and thus the trajectory of the material on the screen.

[0003] The existing vibrating screen body does not have a cleaning structure, so when the vibrating screen is in use, the pores cannot be cleaned in time when the material blocks the pores, which reduces the screening effect. When cleaning the screen plate, the screen plate needs to be disassembled as a whole for cleaning, which is very inconvenient and will delay work efficiency. Utility Model Content

[0024] The cleaning member 54 includes a rack 540, the top of the rack 540 is fixed to the bottom of the connecting rod 52, the bottom of the rack 540 passes through the sliding frame 41, and the rack 540 is slidably connected to the sliding frame 41, and the rack 540 is slidably connected to the inner wall of the vibrating screen body 1. The output shaft of the motor 2 passes through a pinion 541, and the pinion 541 is fixedly connected to the output shaft of the motor 2, and the pinion 541 is rotatably connected to the inner wall of the vibrating screen body 1, and the pinion 541 is meshed with the rack 540. The inner wall of the vibrating screen body 1 is rotatably connected with a half gear 542, and the half gear 542 is meshed with the rack 540. The rotation of the output shaft of the motor 2 will drive the pinion 541 to rotate, and when the pinion 541 rotates, it will drive the rack 540 to move, thereby making The rack 540 drives the connecting rod 52 to move, so that the connecting rod 52 can drive the dredging plate 53 to move upward, so that the top pin of the dredging plate 53 can dredge and clean the pores of the sieve plate 3. At the same time, the rack 540 moves and drives the half gear 542 to rotate. When the pinion 541 is no longer engaged with the rack 540, the pinion 541 will engage with the half gear 542, thereby causing the half gear 542 to reverse, so that the half gear 542 can drive the rack 540 to move downward, and then drive the dredging plate 53 to move downward, so that the top pin of the dredging plate 53 can reciprocate to clean the pores of the sieve plate 3, effectively preventing the vibrating screen body 1 from blocking the pores when in use, thereby affecting the screening effect, and effectively cleaning the sieve plate 3.

[0025] The screening assembly 4 includes a fixed plate 40, which is fixed to the inner wall of the vibrating screen body 1.

At this time, the output shaft of the motor 2 drives the cam 43 to rotate, and then the cam 43 pushes the slide frame 41, so that the slide frame 41 drives the screen plate 3 to vibrate, and then the material can be screened. At the same time, the rotation of the output shaft of the motor 2 drives the pinion 541 to rotate. When the pinion 541 rotates, it drives the rack 540 to move, and then the rack 540 drives the connecting rod 52 to move, so that the connecting rod 52 can drive the dredging plate 53 to move upward, so that the top of the dredging plate 53 can be aligned with the holes of the screen plate 3. The gap is cleared and cleaned, and at the same time, the rack 540 moves to drive the half gear 542 to rotate.
