Sand screening equipment for house construction

Abstract

The invention belongs to the field of house construction, in particular to sand screening equipment for house construction. The sand screening equipment comprises a machine frame, wherein a screeningbox is fixed to the machine frame; the upper end of the screening box is opened; a rotating sieve, a sliding sieve and a swinging sieve are sequentially arranged in the screening box from top to bottom; the pore sizes of sieve holes of the rotating sieve, the sliding sieve and the swinging sieve are sequentially reduced; the rotating sieve is rotatably connected to the inner wall of the screeningbox; a plurality of grinding shafts are rotatably connected to the machine frame, and grinding discs are fixed to the lower ends of the grinding shafts; the sliding sieve is vertically connected to the inner wall of the screening box in a sliding manner, and a first connecting rod is fixed to the upper end of the sliding sieve; the swinging sieve comprises a first half sieve and a second half sieve, and the first half sieve and the second half sieve are separately hinged to the opposite two sides of the inner wall of the screening box, and an elastic band is fixedly connected between the opposite ends of the first half sieve and the second half sieve; and a second connecting rod is fixed between the elastic band and the sliding sieve. By adopting the scheme, the problem that graded screening on sand is inconveniently performed can be solved.

Description

technical field [0001] The invention belongs to the field of house construction, and in particular relates to sand screening equipment for house construction. Background technique [0002] Screening is the process of using a sieve to make the fine-grained materials smaller than the sieve holes pass through the sieve surface, while the coarse-grained materials larger than the sieve holes stay on the sieve surface, thereby completing the process of separating coarse and fine materials. Sand is a must in construction engineering. One of the few materials, a large amount of sand screening is often required in housing construction projects to remove large particles of sand and some impurities in the sand, so that the purity of the material can be improved, and the quality of construction projects can be increased. Construction projects are usually carried out on sand When sifting sand, sand screening devices are used. [0003] The sand particles in the sand are also divided into...
