The anti-blocking device is directly arranged on a screen mesh of a vibrating screen in the actual use process, one end of the anti-blocking flapping main body 1 is fixedly connected with a blanking end of the screen mesh, and the other end of the anti-blocking flapping main body is freely arranged along the material running direction; the anti-blocking beating main body 1 is in a horse whip shape due to the design, and the beating unit can be a first-stage beating unit and also can be a second-stage beating unit or a multi-stage beating unit. When the screen cloth vibrates, the anti-blocking beating main body 1 vibrates along with the vibration of the screen cloth, so that the screen surface of the screen cloth is continuously beaten, and materials blocked in the screen holes are directly beaten. The anti-blocking beating main body 1 vibrates along with the vibration of the screen, so that the blocking of the screen is effectively prevented. This anti-blocking device, need not set up anti-blocking device's power in addition, rely on the vibration of screening machine self to realize patting the screen cloth completely, moreover, the steam generator is simple in structure, and convenient for operation, simultaneously, because prevent stifled net surface of patting the main part and directly patting the screen cloth, therefore, prevent stifled effect more obvious, moreover, no matter the screening machine is provided with several layers of screen cloth and all can set up this anti-blocking device on the net surface, not receive the restriction of what screen cloth quantity, also can set up many anti-blocking on the net surface of same screen cloth and pat the main part, screen cloth net surface to different positions is patted stifled.
This anti-blocking device wholly sets up the soft whip that is similar verbus structure, can not constitute the injury to the screen cloth, has effectively solved the defect that anti-blocking device among the prior art can not directly set up and need power device on the wire side. The screening machine is energy-saving, precise and simplified, the maintenance period of the screening machine is shortened, the service life of the screening machine is prolonged, and the anti-blocking device can be applied to any screening machines and vibrating screens with screen structures, so that the universal design is realized. The method can achieve good technical effect in practical mine application.
The above-described embodiments are only some, but not all embodiments of the present invention. Meanwhile, based on the embodiments described in the present invention, all other embodiments obtained on the basis of the technical solutions of the present application by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
