Rapid sand screening device for municipal construction

Abstract

The invention discloses a rapid sand screening device for municipal construction. The rapid sand screening device for municipal construction comprises an operation box. A driving motor is fixedly mounted at the top of the operation box. A driving shaft is coaxially and fixedly mounted on an output shaft of the driving motor. A turning wheel is rotatably arranged on the inner side wall of the operation box. A screening tank is horizontally arranged in the operation box. A second right guide rod is horizontally and slidably arranged on a limiting support. An incomplete gear connected with a straight rack in an engaged mode is fixedly arranged on the outer surface of a driven shaft in a sleeving mode. According to the rapid and screening device for municipal construction, scattering rods rotate to rotatably scatter sand in the screening tank so that the sand can easily pass through the screening tank to enter a collection tank, the turning wheel rotates to drive the screening tank to reciprocate leftwards and rightwards through guide rods, so that the sand is promoted to shake back and forth, and the screening speed of the sand is increased; and a hollow-square frame reciprocates leftwards and rightwards to drive a brush plate to reciprocate leftwards and rightwards through the second right guide rod and to scrape the screening tank repeatedly, so that it is ensured that sieve holes in the bottom of the screening tank are normal and are prevented from being blocked, and the screening efficiency of the sand is effectively improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a quick sand screening device for municipal construction. Background technique [0002] Buildings are structures built by people using all available materials such as soil, stone, wood, steel, glass, reeds, plastics, and ice. Architecture itself is not an end, the purpose of architecture is to obtain the "space" formed by architecture. It is an artificial environment created by people in order to meet the needs of social life, using the material and technological means they have mastered, and using certain scientific laws, feng shui concepts and aesthetic principles. [0003] In the construction process, a large amount of sand is needed. Sand is mixed with crushed stones and cement to form cement mortar. As the most widely used building material, due to construction requirements, sand needs to be screened to obtain a finer material. Sand, to remove large grains o...

[0003] In the construction process, a large amount of sand is needed. Sand is mixed with crushed stones and cement to form cement mortar. As the most widely used building material, due to construction requirements, sand needs to be screened to obtain a finer material. Sand to remove large particles of sand and other debris, the current sand screening device has a poor screening effect on sand, and the screening efficiency is low
