An anti-blocking material device and a screening machine with the same

Abstract

The invention discloses an anti-blocking material device, comprising: an anti-blocking flapping main body, an elastic material body arranged on a mesh surface of a screen mesh to automatically flap and prevent blocking the screen mesh; the anti-blocking flapping main body comprises a plurality of series connected The flapping unit; the flapping unit includes a flapping whip rod and a flapping whip head; the hardness of the flapping whip rod is smaller than that of the flapping whip head. Also disclosed is a screening machine with an anti-blocking material device, comprising: a screening machine driving unit, a screening machine excitation unit, a screen mesh unit and an anti-blocking material device arranged on the screen mesh surface of the screen mesh unit. The anti-blocking device does not need to set up a power device, and is directly installed on the screen surface to rely on the vibration of the screening machine to automatically beat the screen, which realizes the energy saving and simplification of the screening machine, reduces the maintenance period of the screening machine, and prolongs the The service life of the screening machine is prolonged, and the universal design is realized.

Description

technical field [0001] The invention relates to the technical field of screening machines, in particular to an anti-blocking material device and a screening machine with the same. Background technique [0002] The screening machine in the existing mining machinery is prone to the phenomenon that the screen is blocked during the use process. In actual operation, after the screen is blocked, it is usually manually operated and beaten with a hammer, but manual operation is laborious. The strength is high, the dust generated during the beating process is not good for the health of workers, and the anti-blocking effect is not ideal. At present, there are also screening machines that use a flapping mechanism. [0003] For example, a Chinese patent document (announcement date: November 10, 2017, announcement number: CN 105665278B) discloses a flapping vibrating screen, including a driving mechanism, a flapping mechanism and a swinging mechanism driven by the driving mechanism, and...

Problems solved by technology

[0005] The above technical solution realizes the beating of the sieve body by setting the beating mechanism multi-frequency vibrator at the bottom of the sieve body, and this way of setting the beating mechanism at the bottom will have a better effect on the single-layer screen or the bottom screen , but for the screen with multiple layers, the upper screen will be far away from the beating mechanism and the beating effect will be reduced, so it cannot effectively achieve good anti-clogging performance of each layer of screen
