Description

Technical Field

[0001] The utility model relates to the technical field of sand screening for construction projects, in particular to sand screening equipment for construction projects. Background Art

[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 foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. In the process of building construction, it is usually necessary to screen the sand and take out the large stones to make the sand meet the use requirements.

[0003] For example, a sand screening device for construction projects with application number 202222419171.0 includes a bottom plate, a bracket fixedly connected to the outside of the bottom plate, a shell fixedly connected to the top of the bracket, a motor fixedly connected to the outside of the shell, an auger fixedly connected to the outside of the motor, a heating plate arranged on the inside of the shell, a conveyor belt fixedly connected to the outside of the bracket, a support plate fixedly connected to the outside of the bottom plate, a limit rod fixedly connected to the inside of the support plate, a slider slidingly connected to the outside of the limit rod, a screen fixedly connected to the outside of the slider, a vibrator fixedly connected to the bottom of the screen, a spring fixedly connected to the outside of the slider, and a collection box arranged on the inside of the support plate. This sand screening device for construction projects avoids the problem of sand blocking the screen, and also avoids the problem that when the sand is relatively damp, it will not slide down completely when it falls on the receiving plate, and sometimes needs to be scraped manually. However, this screening device lacks a structure of a mobile unloading device when putting sand on the top of the screen plate, which makes it easy for sand to accumulate on the top of the screen plate, thereby affecting the sand screening effect.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a sand screening equipment for construction engineering is proposed. Utility Model Content
