Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sand screening machines, and particularly relates to a sand screening machine. Background Art
[0002] Sand screening is often performed during construction projects. Traditional manual screening methods are inefficient, so a sand screening machine has been designed. Existing sand screening machines typically require manual cleaning of the stones trapped on the screen, which is cumbersome and labor-intensive.
[0003] Sand screening machine is a mechanical equipment, mainly used for screening soil, impurities and other substances in sand and gravel or similar materials. The sand screening machine is mainly composed of a frame, a vibrating screen, a conveyor belt, an electric motor, etc. It has high screening efficiency and strong adaptability. Common sand screening machines include conical sand screening machines, linear sand screening machines, etc. The working principle of the sand screening machine is that under the action of the motor, high-frequency vibration is generated on the vibrating screen, and sand and gravel are separated from impurities through the sieve holes. The main advantage of the sand screening machine is that it can effectively improve the screening efficiency and can classify and screen sand and gravel of various particle sizes.
[0004] The current sand screening machines on the market are not easy to control the particle size of sand and gravel during operation. When the screened sand and gravel contain a lot of large particles of agglomerated sand and gravel, the agglomerated sand and gravel may get stuck in the screen, affecting the normal use of the screen. At the same time, if the agglomerated sand and gravel need to be broken up before use, an additional process is required to break up the agglomerated sand and gravel, which brings many inconveniences to the operation. For this reason, an improved sand screening machine is designed. Utility Model Content
