AI Technical Summary

Technical Problem

Existing seed sample crushing equipment suffers from problems such as low crushing efficiency, uneven crushed particles, and discontinuous feeding, resulting in some seeds being under-crushed or over-crushed.

Method used

The design incorporates a second rotating shaft driven by a servo motor, along with a sleeve, hammer plate, and crushing blade. Combined with a bevel gear mechanism and sliding connecting block, it achieves efficient crushing of seed samples. Simultaneously, through an intermittent feeding mechanism, the seed samples are fed intermittently with deceleration by the linkage of a synchronous wheel and a control plate.

Benefits of technology

It significantly improves crushing efficiency and impact force, ensures the continuity and efficiency of the crushing process, and enhances the operational reliability and service life of the equipment.

Abstract

The utility model relates to the technical field of seed crushers, and discloses a sample crusher for seed processing, which comprises a case, the top of the case is fixedly connected with a servo motor, an output shaft of the servo motor is fixedly connected with a second rotating shaft, and the outer surface of the second rotating shaft is slidably sleeved with a sleeve. By arranging a second rotating shaft driven by a servo motor and combining rotation of the sleeve, a hammering plate and a crushing cutter, efficient crushing of a seed sample at the top of the sieve plate is achieved. Meanwhile, a rotating disc driven by a bevel gear mechanism is matched with a sliding column to slide a connecting block, so that a sleeve can slide back and forth along the outer surface of a second rotating shaft to drive a plurality of circular blocks on a hammering plate to impact back and forth, and the crushing efficiency and the impact strength are remarkably improved.
