Description

Technical Field

[0001] The utility model belongs to the technical field of dust prevention of vibrating screens, in particular to a dust prevention device for a mining vibrating screen. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator. Mining vibrating screens can be divided into: high-efficiency heavy-duty screens, self-centering vibrating screens, elliptical vibrating screens, dewatering screens, circular vibrating screens, banana screens, linear vibrating screens, etc. Existing mining vibrating screens will generate a lot of dust during the vibrating screening process, and the high dust concentration not only seriously pollutes the working environment in the mine, but also increases the harm to the human body and may even damage the machinery and equipment, so dust-proof devices are installed in the vibrating screen.

[0003] Existing dust prevention devices mostly use suction devices to directly suck away the dust, filter it, and then discharge it. However, the vibrating screen in the mine generates a lot of dust, and the filter needs to be cleaned or replaced frequently. Currently, cleaning is mostly done manually, and a lot of dust will be generated during the cleaning process, which can still cause harm to the human body. Utility Model Content

[0004] The purpose of the utility model is to provide a dust-proof device for a mining vibrating screen. A dust removal mechanism is set up, specifically, the dust removal mechanism is moved toward the dust-proof box by retracting the electric push rod. When pushed again, two dust removal rollers are driven to rotate three times to adhere the dust on the top and bottom of the filter screen. This solves the problem that the existing mining vibrating screen generates a lot of dust, and the filter screen needs to be cleaned or replaced frequently. Currently, cleaning is mostly done manually, and a lot of dust is generated during the cleaning process, which can cause harm to the human body.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

By setting the dust removal mechanism, specifically, the dust removal mechanism is moved toward the dustproof box by retracting the electric push rod, and then the two dust removal rollers are driven to rotate when pushed to adhere the dust on the top and bottom of the filter net, thereby achieving the effect of dust removal on the filter net, without the need for manual dust removal, and the problem of manual dust generation during the cleaning process or causing harm to the human body will not occur. The service life of the filter net is also increased by increasing the number of cleaning times, and it does not need to be replaced frequently, saving costs.

[0008] Furthermore, a feed port and a dust suction pipe are fixedly connected to the top of the vibration box, a fan is arranged on the inner wall of the dust suction pipe, a motor is fixedly connected to the back of the vibration box, a rotating rod is fixedly connected to the front output end of the motor, and a swing block is fixedly connected to the outer surface of the rotating rod, and the purpose of hitting the vibration screen is achieved by starting the motor to drive the swing block to rotate, so that the vibration screen can shake, and the dust in the vibration box is sucked away by the fan.
