AI Technical Summary
Existing sand and gravel screening devices cannot efficiently and quickly perform multi-stage separation and screening. Furthermore, sand and gravel tend to flow from small apertures to large apertures under gravity, resulting in smaller sand particles not being fully screened out, thus reducing screening efficiency.
A sand and gravel screening device was designed, which uses a rotatable primary filter cartridge in conjunction with an intercepting semi-ring plate and a vibrating motor. The primary filter cartridge is rotated by a servo motor driving the active gear ring, and the vibration of the vibrating motor is combined with the vibration of the primary filter cartridge to achieve dynamic screening of sand and gravel. Multi-stage screening is carried out by using multi-stage filter plates and guide plates to ensure that fine sand and gravel debris are fully screened out.
It improves the efficiency and screening effect of sand and gravel screening, ensures the complete screening of fine particles, and significantly improves the overall screening efficiency.

[0021] The working principle of the above technical scheme is as follows: in use, the operator puts the gravel to be screened into the primary filter cylinder 13 through the feeding cylinder 5, and starts the servo motor 18 to rotate, which drives the driving gear 19 and the driven gear ring 20 to rotate, thereby driving the primary filter cylinder 13 to rotate under the support of the support bearing ring 17 and the fixed ring 14. At the same time, the vibration motor 23 moves to cause the shell 4 to vibrate. At this time, the gravel in the primary filter cylinder 13 is slowly rotated and transmitted through the interception of the interception half-ring plate 24, and cooperates with the rotation and slight shaking of the primary filter cylinder 13 to promote the separation of the gravel. The largest one is guided to the top of the guide slope 8 through the primary filter cylinder 13, and the large gravel is bounced to the outside of the shell 4 through the second discharge port 7 under the action of the elastic force of the inclined elastic expansion rod 21.
