Description

Screening plant of cereal destoner

Technical Field

The utility model relates to the technical field of grain stoners, in particular to a screening device of a grain stoner.

Background

A grain stone remover is a machine for removing impurities such as stones mixed in grains during processing.

The material gets into the sieve from the feed inlet, because the material all possesses certain speed, so the material of different quality can possess different energies. The material that quality is big moves on the sieve and can be more violent than the material that quality is little, and it can overcome the frictional force between the material and reach the upper strata of material, and the material that quality is little then can reach the lower floor of material to separate from the material through the sieve mesh.

And current destoner is detaching the in-process of stone, and the small stones fall through the sieve mesh and deposit and be difficult for the clearance, and too much the screening work that lasts to screening plant of deposit stone causes the influence, and deposit the stone also causes the trouble in follow-up clearance process to the device for it wastes time and energy to clear up more, so need have the clearance mechanism that can clear up the small stones that the sieve mesh falls down simultaneously, consequently, I propose the screening plant of a cereal destoner.
