technical field

The invention relates to the technical field of equipment related to construction engineering, and more specifically, the invention relates to a sand screening device with better screening effect.

Background technique

Sand is an essential basic raw material in the field of construction. There are many kinds of impurities in the sand, such as gravel, garbage, etc. The sand in the sand is also divided into different grades, and the different uses require different particle size grades of the sand. , which requires the use of a sand screening device to screen the sand, which can meet the needs of actual use.

In the existing published documents, the invention patent of patent publication number CN112642701A discloses a kind of sand screening device for building construction engineering with better screening effect, including a main body, the inner surface of the main body is fixedly connected with a shell, and the outer surface of the shell is The internal movable connection is connected with a rotating shaft, the external of the rotating shaft is fixedly connected with a sprocket, the external of the sprocket is engaged with a chain, and the external of the chain is fixedly connected with a sealing plate; through the rotating shaft, push wheel, rotating rod, rack, gear one, gear 2. The interaction between the tie rod, the connecting component and the fixed component can drive the sieve plate to swing up and down when the sand is sieved, and at the same time, the swing amplitude can be adjusted, so that the flow speed of the sand on the surface of the sieve plate can be increased. It avoids the situation that the sand screening efficiency is low due to the high friction force between the sands, which makes the flow velocity too slow, which is conducive to improving the sand screening efficiency and can meet the needs of actual use.

According to the above-mentioned sand screening device, when the sieve plate is in an inclined state, the sand will fit on the inclined surface of the entire sieve plate, and the sand will not be rolled when it is mixed and vibrated, which will cause the coarse-grained sand to fall under the action of gravity. If the sand is accumulated in the holes of the sieve plate, the fine-grained sand will be above the coarse-grained sand, which makes it difficult for the fine-grained sand to pass through the sieve plate, and the sand screening is not thorough enough, and the sand needs to be re-screened points, affecting the efficiency of sand screening.
