Sand sieving device for civil engineering

Abstract

The invention discloses a sand sieving device for civil engineering. The sand sieving device comprises a box body, a feeding hopper, a feeding channel, a pulverizing device, a sand sliding plate, a first spring, a sand and gravel rotating fan, a first sieve net, a second sieve net, a second spring, a third motor, a disc, a moving rod, a cross rod, a vertical rod and a hitting ball, wherein the pulverizing device comprises a first motor, a stirring shaft and a pulverizing rod; and the sand and gravel rotating fan comprises a second motor, a mounting shaft, a fan plate and a hot air blower. By arranging the pulverizing device, caking sand and gravel are pulverized, and insufficient sieving is avoided; by arranging the sand and gravel rotating fan, insufficient sieving caused by too-high sandfalling speed is avoided, and at the same time, the sand and gravel are dried, so that the blocking of sieve net holes by the wet sand and gravel and the influence of engineering use are avoided; byarranging the first sieve net, the second sieve net, the third motor, the disc, the moving rod, the cross rod and the hitting ball, multi-stage sieving can be carried out; and by driving the first sieve net and the second sieve net to swing upwards and downwards through cooperation, the sieving efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of civil engineering equipment, in particular to a sand screening device for civil engineering. Background technique [0002] With the development of the economy and the rapid development of science and technology, people's living standards are gradually improving, and the construction of the country is also proceeding rapidly. In real life, a large number of houses, roads and bridges are being built. These projects are collectively referred to as For civil engineering, sand and gravel are used in the construction process of civil engineering, but sometimes the size of the sand and gravel required is different, so a screening device is required to screen the sand and gravel. Most of the sand and gravel used in the construction site are sieve However, the current sand screening device has a low sand screening efficiency and a fast sand falling speed, resulting in insufficient screening, and generally only has...

[0002] With the development of the economy and the rapid development of science and technology, people's living standards are gradually improving, and the construction of the country is also proceeding rapidly. In real life, a large number of houses, roads and bridges are being built. These projects are collectively referred to as For civil engineering, sand and gravel are used in the construction process of civil engineering, but sometimes the size of the sand and gravel required is different, so a screening device is required to screen the sand and gravel. Most of the sand and gravel used in the construction site are sieve However, the current sand screening device has a low sand screening efficiency and a fast sand falling speed, resulting in insufficient screening, and generally only has a first-level sand screening function.
