[0002] A stone remover is a device for removing impurities such as stones and sand from crops such as grains and beans. Its working principle is to separate impurities from grains by using the filtering function of a sieve mesh. The stone remover mainly consists of a feed hopper, a sieve mesh, a fan, a motor, etc. During operation, the material enters from the feed hopper, passes through the sieve mesh for filtration, the impurities are left on the sieve mesh, and the grains pass through the sieve mesh and enter the next process.

[0003] In the prior art, as disclosed in a Chinese patent with the patent publication number CN218282591U, a rice stone remover includes: a feed inlet, a distribution block with an overall conical shape facing the feed inlet, a plurality of vibrating mesh plate assemblies provided at the lower part of the distribution block, the plurality of vibrating mesh plate assemblies are arranged around the axis of the distribution block, one end of the vibrating mesh plate assembly close to the distribution block is the feed end, one end of the vibrating mesh plate assembly far from the distribution block is the discharge end, the height of the discharge end is lower than that of the feed end, the discharge ends of the plurality of vibrating mesh plate assemblies jointly form a ring shape, the rice stone remover further includes an aggregate frame, an annular feed ring facing the discharge end is provided at the upper part of the aggregate, and a discharge port communicated with the feed ring is provided at the lower part of the aggregate frame; a step plate is provided at the discharge end.
