A sand and gravel screening device with controllable sieve holes in building construction

Abstract

The invention relates to a sand and gravel screening device with controllable screen holes in building construction, comprising a bottom plate, a separation mechanism and a circulating feeding mechanism. , the circulating feeding mechanism is connected with the separating mechanism. The invention can conveniently transport the sand and gravel upwards into the separation mechanism through the circulating feeding mechanism, the upwardly transported sand and gravel can be screened by the separation mechanism, and the screening size of the sand and gravel can be arbitrarily changed through the separation mechanism during the sand and stone screening process. In this way, it can avoid operating the forklift to load the sand and gravel, thereby improving the screening efficiency of the sand and gravel.

Description

technical field [0001] The invention relates to a screening device, in particular to a sand and gravel screening device with controllable screen holes in construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of project 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 construction site is called "building construction site" or "construction site", also called construction site. [0003] In the prior art, such as the patent with the publication number CN112620068A, a sand and gravel screening device is disclosed, which includes a bracket, a driving component, a screening sleeve and a discharging component...

AI Technical Summary

Problems solved by technology

[0005] The first point is that the gravel screening device occupies a large area, so it is not suitable for use on construction sites with small spaces. At the same time, the screening size of sand and gravel cannot be changed arbitrarily during the sand screening process.

[0006] The second point, because of the sand and gravel screening device, when screening the sand and gravel, most of the workers operate the existing forklift equipment to pour the sand and gravel into the equipment, and the sand and gravel are screened by this equipment. less efficient
