Example Embodiment

[0023] Example 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 provided with a pre-screening sand component and a grading screening sand component in sequence from top to bottom. The specific types of components are not limited. In this embodiment, preferably, the pre-screening sand component includes a first sieve plate 16, a return spring 17, a fixed plate 18, and a driven shaft 23. The first sieve plate 16 movably penetrates 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 screen box 1, the other end of the first screen plate 16 is connected with a driving member 6 that drives it to move left and right, and the driven shaft 23 is rotatably installed in A drive assembly is connected to the top of the first sieve plate 16 and one end extending to the out...

Example Embodiment

[0032] Example 2

[0033] See Figure 4 In order to dampen the device, this embodiment is further improved on the basis of embodiment 1. The improvement lies in: 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 shock-absorbing spring 2003 is fixedly installed between the sleeve rod 2001 and the sleeve 2002.

[0034] In summary, the pre-screening sand component and the grading screening component are driven to work at the same time by the driving component, and the scraper 22 in the pre-screening sand component rotates to flip the accumulated sand on the first screen 16 to prevent accumulation and improve the efficiency of sand screening; The second sieve plate 14 in the grading sieve sand assembly realizes grading and sieve sand according to the size of the sand,...

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 ...
