AI Technical Summary
Existing sand and gravel sorting equipment vibrates excessively, generates a lot of noise, and is prone to component damage due to vibration, which shortens the equipment's service life. Furthermore, the sorting process is not thorough enough.
The system employs a spring terminal and flexible rubber ball buffer structure, combined with a stirring rod and screening tank design. The spring terminal absorbs vibration, the flexible rubber ball buffers impact force, the screening tank screen holes on the inner wall separate sand and gravel of different particle sizes, and the stirring rod improves the sorting efficiency.
It reduces equipment wear, improves sorting accuracy and efficiency, extends equipment service life, and meets the sorting needs of sand and gravel of different particle sizes.
