Aggregate screening device for buildings

Abstract

The invention discloses an aggregate screening device for buildings. The aggregate screening device comprises a base and a screening box, wherein a plurality of iron blocks are arranged on the upper side of the base; a spring is arranged on the upper side of each of the iron blocks; an electromagnet is connected to the upper end of each of the springs; a support platform is arranged on the upper sides of the electromagnets; a sliding rail is arranged on the upper side of the support platform; support plates are arranged at the lower end of the screening box symmetrically; the lower ends of thesupport plates are connected with the sliding rail; a motor is arranged at the right end of the upper side of the support platform; a rotating disc is arranged at the output end of the motor; a rotating shaft is arranged on the periphery of the front side of the rotating disc; a connecting seat is arranged on the right side of the support plate on the right side; a connecting rod is arranged between the connecting seat and the rotating shaft; a dust collection box is arranged at the right part of the upper end of the screening box; a fan is arranged at the upper end of the dust collection box; a dust collection pipe is arranged at the output end of the fan; and a dust collection cover is arranged at one end of the dust collection pipe. The aggregate screening device for buildings has thebenefits of being simple in structure, convenient to use, good in screening effect, long in service life, good in dust collection effect, and energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a sand screening device for construction. Background technique [0002] With the development of the economy and the improvement of people's living standards, the construction industry has been carried out on a large scale throughout the country. in, [0003] In the process of building construction, sand and gravel of various sizes need to be applied. Sand and gravel refer to the loose mixture of sand grains and crushed stones. In geology, mineral or rock particles with a particle size of 0.074 to 2mm are called sand. Those with a particle size greater than 2mm are called gravel or breccia. The difference between the two lies in the degree of rounding. If the gravel in the sand is mostly gravel, it is called sand gravel. In daily life, some people also call sandstone sandstone. At present, sand and gravel need to be screened in the process of processing. The purpo...

AI Technical Summary

Problems solved by technology

At present, sand and gravel need to be screened in the process of processing. The purpose of sand and gravel screening is to separate the larger particles from the smaller particles in the sand. The structure design of the current sand and gravel screening device is unreasonable. The effect is not good, and the screen will be blocked after a long time of use, which not only reduces the work efficiency, but also greatly increases the work cost
