Sand making equipment for construction

Abstract

The invention discloses sand making equipment for construction. The sand making equipment for construction comprises a main machine, a swing arm and a bucket; one end of the swing arm is matched withthe main machine, and the other end of the swing arm is matched with the bucket; the bucket comprises a discharging channel, a screening opening in the bottom face of the bucket, a first filtering piece, a second filtering piece and a vibrating piece for driving the first filtering piece and the second filtering piece to vibrate; a first elastic drive piece is arranged between the vibrating pieceand the first filtering piece; and a second elastic drive piece is arranged between the vibrating piece and the second filtering piece. By arranging the first filtering piece and the second filteringpiece on the bucket, the screening operation can be conducted directly after the bucket dredges mud without independently arranging screening facilities, and cost input of restoration work is reduced;and the operation of manually carrying mud is directly omitted, so that the working efficiency is improved and labor input is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to sand making equipment for construction. Background technique [0002] A large amount of concrete is needed in the process of building construction, and concrete is made by mixing cement, sand, and gravel in appropriate proportions and then adding water and stirring. With the acceleration of urban construction in recent years, the amount of concrete that needs to be used has increased by nearly three times, so the demand for crushed stone is also increasing. However, gravel in the natural environment is a non-renewable energy source. Under such a large demand, there has been a shortage of gravel resources. In order to solve this problem, people began to use construction waste, and the demand for natural gravel was solved by breaking the construction waste into gravel. [0003] However, there are problems in existing crushing equipment. Although a part is not eas...

AI Technical Summary

Problems solved by technology

[0003] However, there are problems in the existing crushing equipment. Although a part is not easily damaged, the crushed stones obtained by crushing are relatively large in size, which will affect the effect of the prepared concrete.

Although the other part has a better crushing effect, the damage of the crushing tool is more serious and the service life is short.
