Building construction gravel screening device capable of controlling screen holes

Abstract

The invention relates to a building construction gravel screening device capable of controlling screen holes. The building construction gravel screening device comprises a bottom plate, a separating mechanism and a circulating feeding mechanism. The separating mechanism is mounted at the top of the bottom plate, the circulating feeding mechanism is arranged on one side, close to the separating mechanism, of the top of the bottom plate, and the circulating feeding mechanism is connected with the separating mechanism. According to the building construction gravel screening device capable of controlling the screen holes, gravel can be conveniently conveyed upwards into the separating mechanism through the circulating feeding mechanism, the gravel conveyed upwards can be screened through the separating mechanism, the screening size of the gravel can be changed at will through the separating mechanism in the gravel screening process, in this way, it can be avoided that a forklift is operated to feed the gravel, the gravel screening efficiency can be improved, the position of a feeding pipeline can be adjusted in a swinging mode through an adjusting mechanism, and in this way, the gravel can be conveyed upwards conveniently.

Description

technical field [0001] The invention relates to a screening device, in particular to a sand and gravel screening device with controllable sieve holes in building 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 physical objects at designated locations. It includes basic engineering construction. , main structure construction, roofing engineering construction, decoration engineering construction, etc., the place where the construction work is called "building construction site" or "construction site", also called construction site. [0003] In the prior art, for example, the patent whose publication number is CN112620068A discloses a gravel screening device, which includes a bracket, a drive assembly, a screening sleeve and a ...

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
