Technical Field

The invention relates to the technical field of building construction equipment, in particular to a sand screening machine for a building.

Background

On a building construction site, sand materials are often required to be screened before concrete is mixed so as to avoid the influence on building quality caused by river mud or even large impurities mixed in the sand materials. The screening of the prior sand materials is mostly realized by obliquely placing a screen to ensure that the screen is obliquely placed, then manually spraying the sand materials to the screen, and rolling the sand materials on the screen surface under the action of gravity to achieve the purpose of screening. Such screening process, the sand material volume that the single sprinkled to the sifter can not be too much, and the interval of spilling to the sifter has certain restriction moreover, and the sand material that needs the sifter rolls the sand material and just can shed the sand material once more when totally, in case the sand material piles up the influence screening effect. The consequence of doing so is that the screening efficiency of sand material has just greatly reduced, and then causes the time delay to the construction.

Disclosure of Invention

The invention aims to provide a building sand screening machine, which has the advantages that the sand screening machine does not need to manually feed materials into the device for multiple times, the workload of workers is reduced, and the screening does not have time intervals, so that the screening efficiency is improved.

In order to achieve the purpose, the invention provides the following technical scheme: a sand screening machine for buildings comprises a motor, a screen frame, a machine body and a supporting plate, wherein four upright columns are mounted at the bottom of the outer side of the machine body and distributed in a rectangular array at the bottom of the machine body, a discharge hole is formed in the bottom of the machine body in a penetrating mode, the motor is welded on the surface of one side of the machine body, a driving wheel is welded at the output end of the motor, a baffle is arranged at the bottom of the screen frame, supporting rods are mounted around the baffle, a screen is mounted on supporting rods in the screen frame, a rotating shaft is welded on the baffle in a penetrating mode, a driven wheel is welded at the top end of the rotating shaft and is in transmission connection with the driving wheel through a belt, a protective cover is mounted outside the motor, a bearing is welded on the upper surface of the supporting plate, a guide plate is welded outside the bearing, the bottom, the support columns are distributed around the discharge hole.

Preferably, the support columns are distributed around the discharge port in an annular array.

Preferably, the rotating shaft is positioned on one side of the center of the bottom of the screen frame.

Preferably, the driving wheel and the driven wheel are the same in size.

Preferably, the diameter of the screen frame is smaller than the inner diameter of the machine body.

Preferably, the support plate is circular, and the area of the support plate is larger than that of the discharge hole.

Compared with the prior art, the invention has the following beneficial effects:

1. according to the invention, the baffle is arranged, so that the effect of preventing the screened sand from entering the gap between the guide plate and the rotating shaft, thereby causing the sand to enter the bearing, influencing the rotating effect of the bearing and further damaging the rotating shaft is achieved.

2. The screen frame is provided with the plurality of supporting columns, so that the effect of supporting the screen frame is achieved, and the screen frame is prevented from being extruded and deformed by the screen frame due to the fact that excessive sand is filled in the screen frame, and the device is prevented from being damaged.

3. According to the sand screening device, the rotating shaft is arranged on one side of the center of the screen frame, so that the effect that the screen frame is in a deflected state when the rotating shaft rotates to drive the screen frame to rotate is achieved, and sand in the screen frame can be conveniently and rapidly screened.
