Sand screening and grinding equipment for construction engineering

Abstract

The invention belongs to the technical field of constructional engineering equipment and particularly discloses sand and stone screening and grinding equipment for constructional engineering. The sandand stone screening and grinding equipment comprises a frame body, a base and a controller. The top of the frame body is provided with a screening unit. A first guiding unit, a second guiding unit and a third grinding unit are arranged inside the frame body. The first grinding unit comprises a first grinding gear and a second grinding gear. A first fixing rod is divided into two parts, a thick rod and a thin rod. The screening unit comprises a screening cabin, a rotating shaft, a first rotating ring, a second rotating ring and a third rotating ring. The second grinding unit comprises a firstgrinding block and a second grinding block. The third grinding unit comprises a third grinding block, a filter plate and a transmission rod. The sand and stone screening and grinding equipment is simple in structure and convenient to use; sand and stone can be screen and ground effectively; and grinding is conducted completely, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, in particular to a sand screening and grinding equipment for construction engineering. Background technique [0002] With the continuous development of my country's economic construction and the acceleration of urbanization, my country's urban infrastructure and real estate development have developed rapidly, which has promoted a rapid increase in concrete production. Cement and sand are the main raw materials for making concrete. Before grinding the sand and gravel for engineering, it is necessary to preliminarily pulverize the large sand and gravel, and then select the sand and gravel after the preliminary pulverization. Pure, smaller-grained sand and gravel need to be ground. [0003] There are also some technical solutions for sand and gravel screening and grinding in the prior art. For example, a Chinese patent with application number 2017105377648 discloses a sand ...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art and solve the problems that the relatively round sand can not be ground and crushed, the sand is easy to accumulate during the grinding process, causing device failure, and the accumulation of sand causes the problem of grinding and crushing efficiency, a construction project proposed by the present invention Sieving and grinding equipment with sand and gravel
