Rapid cleaning sand screening machine

Abstract

The invention discloses a rapid cleaning sand screening machine, and belongs to the field of sand screening machines. The rapid cleaning sand screening machine comprises a machine frame, material receiving boxes, sand bags, a feeding assembly and a sand screening system. The at least two sand bags are distributed on the inner side of the machine frame at equal intervals, a feeding port and an impurity discharging port are formed in the two ends of each sand bag correspondingly, the feeding ports are used for feeding sand, and the impurity discharging ports are used for discharging materials. The material receiving boxes correspond to the sand bags in number, are located below the sand bags, are annularly placed on the machine frame and are used for receiving the sand or impurities leakingfrom the impurity discharging ports. The feeding assembly is installed on the machine frame and used for adding the sand into the sand bags, continuous operation of a series of operations of sand adding, sand loading, sand screening and impurity removing can be achieved, the sand screening efficiency is high, the impurity removing effect is good, a motor in the operation process can be effectivelyprotected, and the situation that the service life of the motor is shortened due to the fact that the motor is turned off when needed in the operation process is avoided; and in addition, the inclination angle of the feeding assembly can be adjusted, and residual materials in the feeding assembly can be discharged.

Description

technical field [0001] The invention relates to the field of sand screening machines, in particular to a quick-cleaning sand screening machine. Background technique [0002] In construction sites, sand is often used as a raw material, such as when building walls. However, when the sand is transported, it will be mixed with a lot of impurities. Therefore, it is necessary to filter the sand to improve the quality of construction. [0003] However, the existing construction sand screening machines are inconvenient to load materials and cannot perform continuous sand screening operations, requiring frequent cleaning of impurities, which affects the efficiency of sand screening. Therefore, for the above present situation, there is an urgent need to develop a small and quick cleaning sand screening machine to overcome the deficiencies in current practical applications. Contents of the invention [0004] In view of the problems existing in the prior art, the object of the presen...
