Reciprocating shaking type building construction sand screening mechanism with dust suction function

Abstract

The reciprocating shaking type building construction sand screening mechanism with the dust suction function comprises a bottom plate and a rack located at the top end of the bottom plate, a supporting plate is arranged at the top end of the rack at the top end, a shell is arranged at the top end of the supporting plate, a cover plate is arranged at an opening in one side of the shell, the cover plate is connected with the shell through a hinge, and the bottom end of the shell is connected with the bottom plate. A feeding hopper is arranged at the top end of the shell, a transversely-arranged screen frame is arranged in the shell, and a screen matched with the screen frame is arranged in the screen frame. The sand screening machine has the beneficial effects that the screen frame is driven to synchronously reciprocate left and right, the screen shakes in the vertical direction while reciprocating left and right through the design of the reciprocating assembly, and the screen can be in a shaking or vibrating state for a long time to screen impurities and foreign matter in sand grains; the screen is moved out to clean impurities, and the dust suction head and the dust suction box are designed in a matched mode, so that dust generated in the sand screening process can be adsorbed, and the sand screening site environment is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a reciprocating shaking sand screening mechanism for building construction with the function of absorbing dust. Background technique [0002] During construction work, sand sieving is an important part of cleaning the gravel and stones in the sand. The quality of the sand after sieving also directly affects the quality of the entire building, especially in the concrete mixing stage, which depends entirely on the quality of the sand. The current sand screening process generally adopts mechanical sand screening, but some places still use manual sand screening. Although the quality of sand materials can be guaranteed through manual sand screening, manual sand screening will reduce work efficiency and increase time costs. [0003] The surface of the current sand grains or the interior of the sand pile formed as a whole contain some granular impurities, such as larger sa...

AI Technical Summary

Problems solved by technology

[0003]The surface of the current sand grains or the interior of the overall piled sand pile contain some granular impurities, such as large sandstone, metal impurities or foreign matter, etc. , so it needs to be screened before it can be used. Among them, the current sand screening equipment is mostly of a unified type, and all use drum-shaped screens for rotating screening, but only rely on rotating screens to screen sand. The effect is not ideal, that is, the efficiency of sand screening and the nature of the effect during use are reduced at the same time
