Problems solved by technology

[0003] In the process of building construction, sand is one of the most commonly used building materials. In actual use, due to the technical requirements of building construction, sand needs to be screened. The current sand screening device for building construction has a poor screening effect on sand. , the sieve plate is often blocked due to a large amount of sand accumulation, and the screening efficiency is low. At the same time, the sand cannot be effectively classified and screened, which is not conducive to the current construction needs.

Embodiment 1

[0024] see Figure 1-3 , a sand screening device for building construction, comprising a screening box 1, a support column 20 and a base 21, the screening box 1 is sequentially provided with a pre-screening sand assembly and a graded sand screening assembly from top to bottom, the pre-screening sand The specific type of the assembly is not limited. In this embodiment, preferably, the pre-screening sand assembly includes a first sieve plate 16, a return spring 17, a fixed plate 18 and a driven shaft 23, and the first sieve plate 16 is movable through the screening box 1 And one end is connected with the fixed plate 18, the return spring 17 is installed between the fixed plate 18 and the outer wall of the screening box 1, the other end of the first sieve plate 16 is connected with a driving member 6 that drives it to move left and right, and the driven shaft 23 is rotated and installed on the Above the first sieve plate 16 and one end extends to the outside of the screening box ...

Embodiment 2

[0033] see Figure 4 , in order to damp the device, this embodiment is further improved on the basis of Embodiment 1, the improvement is that: the support column 20 includes a sleeve rod 2001 and a sleeve 2002, and the sleeve 2002 is fixedly installed on the base 21, The upper end of the sleeve rod 2001 is fixedly connected with the screening box 1, and the lower end is movably sleeved in the sleeve 2002, and a damping spring 2003 is fixedly installed between the sleeve rod 2001 and the sleeve 2002.

[0034] To sum up, the driving component drives the pre-sand screening component and the graded sand screening component to work at the same time, and the scraper 22 in the pre-screwing component rotates to turn the sand accumulated on the first sieve plate 16 to prevent accumulation and improve the sand screening efficiency; The second sieve plate 14 in the grading and sifting sand component realizes grading and sifting sand according to the size of the sand, and improves the qua...

Abstract

The invention discloses a sand sieving device for building construction. The device comprises a sieving box, supporting columns and a base, wherein a sand pre-sieving component and a sand grading-sieving component are sequentially arranged from top to bottom in the sieving box; the sand pre-sieving component comprises a first sieving plate, a reset spring, a fixed plate and a driven shaft; and thesand grading-sieving component comprises a pushrod, a discharging hopper, a sieving frame, a telescopic rod and a second sieving plate. According to the device, the sand pre-sieving component and thesand grading-sieving component are driven by a driving component to work simultaneously, a scraping plate in the sand pre-sieving component rotates to turn over sand gathering on the first sieving plate, so that accumulation is prevented, and sand sieving efficiency is improved; and the second sieving plate in the sand grading-sieving component realizes sand grading sieving according to the sizeof the sand, so that the sand sieving quality is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a sand screening device for construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] In the process of building construction, sand is one of the most commonly used building materials. In actual use, due to the technical requirements of building construction, sand needs to be screened. The current sand screening device for building ...
