Sand screening machine used for construction

Abstract

The invention discloses a sand screening machine for construction, which comprises a frame, a feeding device is installed on the upper end of the frame, and a material equalizing device is arranged below the feeding device; a vibrating screen is installed inside the frame, and the A supporting frame is installed on one side of the frame, a conveying motor is installed on one side of the supporting frame, a conveying shaft is installed inside the frame and the supporting frame, and a conveyor belt is wrapped on the outside of the conveying shaft. The beneficial effect is that: the feeding motor works, the power is transmitted through the cooperation of the worm and the transmission gear on the outside of the driven wheel, and the feeding screw is driven to rotate, realizing interval and quantitative feeding, and preventing excessive feeding from affecting the sand screening effect; the uniform material motor passes through The rotating rod drives the sliding column to rotate, so that the sliding column slides inside the chute rod, so that the chute rod drives the feeding plate to slide inside the feeding partition through the uniform material sliding rod, thereby changing the feeding through hole and the feeding through hole The relative position of the vibrating screen can make the sand evenly distributed on the surface of the vibrating screen, which helps to improve the efficiency of sand screening.

Description

technical field [0001] The invention relates to the technical field of mechanical devices for construction, in particular to a sand screening machine for construction. Background technique [0002] As an important material for construction projects, sand has strict requirements on its quality. It is necessary to screen out the stones and other sundries inside the sand to ensure the purity of the sand. In order to ensure the quality of the sand, it is necessary to use a sand sieving machine to screen and filter the sand. [0003] The applicant found that there are at least the following technical problems in the prior art: the current sand screening machine cannot realize quantitative feeding at intervals when feeding sand, and cannot ensure uniform feeding at the same time. Insufficient sand will affect the sand screening effect and sand screening efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a sand screening machine f...
