Sand drying and grading device for building construction

Abstract

The invention discloses a sand drying and grading device for building construction. The device comprises a drying box body, wherein a feed hopper is arranged at the top of the drying box body; a double-shaft stirring device is arranged in the drying box body; an electric heater and a humidity sensor are arranged on the inner side wall of the drying box body; a discharge plate is hinged to the bottom of the drying box body; a first vibrating motor is arranged at the bottom of the discharge plate; an annular vibrating basket is arranged at a position obliquely below the discharge plate; a second vibrating motor is arranged on the annular vibrating basket; a screen mesh is arranged in the annular vibrating basket; the bottom of the annular vibrating basket is connected with the top of a fixing groove through a spring; and a collecting basket is arranged in a notch of the fixing groove. According to the device, the sand can be dried and graded, the phenomenon of agglomeration is effectively avoided, the sand with proper water content and proper mesh number is finally obtained, the sand screening efficiency is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a sand drying and grading device for building construction. Background technique [0002] In the process of building construction, sand with a suitable moisture content can meet the normal use of ready-mixed mortar. In addition, when sand is screened, sand with a high water content is easy to form agglomerates, and it is often not well screened when screening. It is easy to block the sieve holes, resulting in a decline in the screening quality. At present, the sand is manually screened in the screening process to obtain fine sand with a suitable mesh. This operation method takes a lot of time and manpower, and its labor intensity is high. Sand sifting is slow. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a sand drying and grading device for building construction, which can eff...
