Sand screening machine for constructional engineering

Abstract

The invention discloses a sand screening machine for constructional engineering. The sand screening machine comprises a main body, wherein a thickening frame is arranged at the upper end of the main body; a conveyor belt is arranged on one side of the thickening frame; a rotary shaft is arranged on the other side of the thickening frame; a baffle plate is arranged on one side of the rotary shaft;a main control box is arranged at the upper end of the baffle plate; a servo motor is arranged at the upper end of the thickening frame; a linear guide rail is arranged at the lower end of the servo motor; and a specially-made screen is arranged at the upper end of the servo motor. According to the sand screening machine for constructional engineering disclosed by the invention, rolling friction generated by the sand screening machine is changed into sliding friction, so that friction force is reduced, and the service life of the sand screening machine can be prolonged; the working speed of the sand screening machine can be controlled, position precision is more accurate, screened materials can be effectively separated and dispersed, and working efficiency and screened material quality areimproved; and moreover, under action of a silica gel net, tiny impurities in the screened materials can be absorbed, so that a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of sand screening machines for construction engineering, in particular to a sand screening machine for construction engineering. Background technique [0002] The sand screening machine for construction engineering is a kind of machine that imitates the artificial use of inclined screens to screen sand. It adopts a flat roller screen drum and ensures that the material flow can be continuously rolled for more than five laps between the multi-turn inner spiral blades in the screen drum. In this way, the sand material is fully dispersed and separated by repeated rolling and sliding. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of this sand screening machine. [0003] Existing sand screening machines for construction projects have certain disadvantages when they are installed and used. During the use of traditional sand screening machin...

AI Technical Summary

Problems solved by technology

[0003] Existing sand screening machines for construction projects have certain disadvantages when they are installed and used. During the use of traditional sand screening machines, the screening materials are often not fully separated and dispersed, resulting in insufficient quality of screening materials, and The sand screening machine cannot freely control the working speed, resulting in too long time-consuming, high cost, and the inability to accurately position the screening material, which has brought certain adverse effects on people's use process. Therefore, we propose a construction engineering sand screening machine
