Description

Technical Field

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

[0002] The role of sand is to fill the gaps between stones and make concrete more compact. In addition, it is combined with cement paste to form cement mortar to improve the workability and fluidity of concrete. In addition to being used in construction, road construction, filtration, aquaculture and beautification, and as a quick-dissolving agent in smelting, it is also the main material for making glass. It contains silicon elements. In sports, in addition to sand pools, it can also be used as sandbags for boxing and flood prevention. It has made an indispensable contribution. In daily life, it plays a clean charm.

[0003] The sand and gravel purchased from the market are generally uneven in coarseness and fineness and cannot be used directly. Workers are required to screen the sand and gravel. An existing device is a sand screening net. Workers use support rods to prop up the sand screening net, and then use a shovel to throw the sand and gravel onto the sand screening net for screening. The screening work efficiency is low in the above manner. At the same time, a lot of dust will be raised when screening the sand and gravel, which will pollute the environment and cause harm to the human body. For this reason, we propose a sand screening equipment for construction. Utility Model Content
