Abstract

The invention relates to the field of construction, in particular to a screening device for construction aggregate. In the construction industry, the aggregate has to be screened for use. The traditional screening device has such problems as poor screening effect, incapability to adjust the screening efficiency according to the impurity level of the aggregate and incapability for automatic feeding. The invention solves the above problems. The aggregate to be screened is conveyed, by conveying spiral blades of which the angles of inclination are adjustable, into an inclined screen; the angles of inclination of the conveying spiral blades can be adjusted according to the angle of the inclined screen, and the angle of the inclined screen can be adjusted according to the impurity level of theaggregate to be screened; when the impurity level is low, the angle of the inclined screen can be increased, and the conveying spiral blades can convey the aggregate at full load, so that the screening speed is high; when the impurity level is high, the angle of the inclined screen can be decreased while the conveying capacity of the conveying spiral blades is reduced, so that the screening effectis good; and the inclined screen can rotate to drive the aggregate to rotate for being screened, and then, impurities and part of fine sand fall onto a reciprocating screen for secondary screening, so that the screening effect is good.

Description

technical field [0001] The invention relates to a construction field, in particular to construction sand and stone screening equipment. Background technique [0002] In the construction industry, sand and gravel must be screened before they can be used. Traditional screening equipment has problems such as poor screening effect, inability to adjust screening efficiency according to the degree of impurities in sand and gravel, and inability to automatically load materials. This invention solves the above problems question. Contents of the invention [0003] The purpose of the present invention is achieved through the following technical solutions: [0004] A construction gravel screening equipment, comprising an inclined screen assembly, an inclined screen rotating assembly, a reciprocating screen assembly and a feeding assembly, the inclined screen assembly is connected with the inclined screen rotating assembly, and the inclined screen rotates The assembly is connected w...
