Automatic sand sieving device for construction material production

Abstract

The invention discloses an automatic sand sieving device for construction material production. The automatic sand sieving device comprises a controller, a base plate, a first motor, a cylinder body, asecond motor, a sieving plate and a stirring rod. The controller further controls the second motor to rotate to drive spiral conveying blades on a conveying rotating shaft to rotate, and sand in a receiving groove can be conveyed to a discharging opening of the cylinder body. The sand discharged through the discharging opening of the cylinder body further slides down a second oblique plate to a feed opening to enter a stirring tank through the feed opening. The first motor rotates to drive the stirring rod on the stirring rotating shaft to rotate, the sand in the stirring tank can be stirred,so that the condition of sand lumps influencing the sand sieving effect is avoided. The sieving plate is used for sieving sand entering into the sieving tank, the sand passing through sieving holes further falls at the bottom of the inner side of the sieving tank, and the sand not passing through the sieving holes is further discharged from the sieving tank through holes along the sieving plate,and therefore automatic sand sieving is achieved.

Description

technical field [0001] The invention relates to a sand screening device, in particular to an automatic sand screening device for building material production. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site; [0003] Sand is a very common building construction material in the process of building construction. It is generally necessary to screen the sand before using it. At present, it generally relies on manual screening of the sand,...

Problems solved by technology

[0003] Sand is a very common building construction material in the process of building construction. It is generally necessary to screen the sand before using it. At present, it generally relies on manual screening of the sand, which wastes a lot of manpower and low screening efficiency. At the same time, sand The sand clusters in the sand will affect the normal screening of sand, and the existing sand screening device does not have the function of automatic screening of sand, so it is not very practical.
