Building screening mechanism

Abstract

The invention discloses a building screening mechanism which comprises a supporting frame and a motor, the motor is installed on the rear side of the left end of the supporting frame, a gearbox is arranged on the front side of the motor, a feeding box is arranged on the right side of the gearbox, a screen A, a screen B, a screen C and a rotating shaft are arranged on the right side of the feeding box, and a screen mesh B is arranged in the screen mesh A. Therefore, carrying and using of the whole building screening mechanism cannot be affected, when the building screening mechanism needs to be used, namely when sand needs to be screened, firstly, the sand needs to be put into the building screening mechanism through a feeding port, then a screen with the needed caliber is selected, and then a classification device is selected, and when a small-caliber screen is needed, the innermost screen slides downwards and then is screwed, so that a power supply is switched on, the sand with the smallest caliber can be directly screened, the screen does not need to be replaced, time does not need to be wasted, and a limited site beside the screen does not need to be occupied.

Description

technical field [0001] The invention belongs to the related technical field of screening materials, and in particular relates to a construction screening device. Background technique [0002] The drum-type sand screening machine imitates the working principle of manual use of inclined screens to screen sand. It adopts a horizontal roller screen drum and ensures that the material flow can be continuously rolled for more than five circles between the multi-turn inner spiral blades in the screen drum, so that the sand The material is fully discrete and separated by repeated rolling and sliding; it is different from the mutual pushing and pressing of large and small materials caused by inclined roller sieve, and the screening process is rushed; it is also different from the vibration, mixing, and high Integrity: Except for the finished material stacking belt conveyor, all systems are integrated into an overall frame, which not only ensures the integrity of the equipment but also...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of construction material screening mechanism, although can play the ability of screening sand particle size through the screen cloth that proposes in the above-mentioned background technology, often can only screen the sand of a kind of particle size when screening, In this way, when sand with other particle sizes is needed, the entire screen needs to be replaced, which is very inconvenient, will greatly delay time, and will also occupy a lot of space.
