Sand and stone sorting device for mechanical engineering

Abstract

The invention provides a sand and stone sorting device for mechanical engineering. The sand and stone sorting device comprises a coarse screening net, a positioning block, a fine screening net, sand storing chamber, a sliding plate, a driven wheel, an alternating-current motor, a conveying belt and a scraping block; the sand storing chamber is formed in the lower side in a screening box, the finescreening net is placed on the upper side of the sand storing chamber, and the coarse screening net is placed on the upper side of the fine screening net; and the positioning block is assembled on theleft side of the lower end face of the coarse screening net. Through the design, the problem that an original screening box is poor in sand and stone sorting effect is solved, the alternating-currentmotor is mounted on the lower side in a feeding box, the driven wheel is assembled on the upper side of the alternating-current motor, the conveying belt is mounted on the annular side face of the driven wheel, the sliding plate is assembled on the upper side of the driven wheel, and the scraping block is mounted on the lower side of the conveying belt; and through the design, the problem that asfor original sand and stone sorting, manual conveying is needed for sorting is solved, and the sand and stone sorting device is reasonable in structure, good in sorting effect and high in working efficiency.

Description

technical field [0001] The invention relates to a sand and gravel sorting device for mechanical engineering, which belongs to the technical field of mechanical engineering. Background technique [0002] Mechanical engineering has always been researching and developing new mechanical products with the goal of increasing production, improving labor productivity, and improving the economy of production, that is, to improve human interests. In the future era, the development of new products will take reducing resource consumption, developing clean renewable energy, and treating, reducing or even eliminating environmental pollution as super-economic goals. [0003] The traditional sand and gravel screening box does not separate sand and gravel thoroughly, resulting in more impurities in the sand and affecting the quality of the sand. The existing sand and gravel screening has no transmission mechanism, resulting in low work efficiency and high cost of use. Now there is an urgent ...

[0003] The traditional sand and gravel screening box does not separate sand and gravel thoroughly, resulting in more impurities in the sand and affecting the quality of the sand. The existing sand and gravel screening has no transmission mechanism, resulting in low work efficiency and high cost of use. Now there is an urgent need for a sand for mechanical engineering. Stone sorting device to solve the above problems
