Description

Agricultural is with cylindric corn miscellaneous separator that goes

Technical Field

The invention relates to the technical field of agricultural machinery, in particular to an agricultural cylindrical rice impurity removal and separation device.

Background

When the specific gravity stoner works, the materials continuously enter the middle part of the stoning sieve surface from the feed hopper. Due to the vibration of the screen surface and the action of air flow passing through the material layer, the porosity among particles is increased, the material is in a fluidized state, automatic grading is promoted, stones with large specific gravity sink into the bottom layer to be contacted with the screen surface, grains with small specific gravity float to the upper layer, and the stones slide to a clean grain outlet under the push of gravity, inertia force and continuous feeding; and the stones with large specific gravity slide upwards relative to the stone-removing screen surface under the action of the inertia force of the screen surface vibration system and the airflow and move to the fine separation area through the stone gathering area. In the prior art, two stages of screens are usually adopted to remove stones from rice, the first stage screen and the second stage screen are obliquely arranged in a mode that one end is higher and the other end is lower, the rice needing stone removal is added into a stone removing machine box from a feeding hole, the rice slides downwards on the first stage screen, because the screen holes are larger than the diameter of the rice, the rice and materials smaller than or equal to the diameter of the rice are leaked onto the second stage screen, stones, rice chaff, straws and the like larger than the diameter of the rice enter a rice chaff outlet, and smaller rice chaff, smaller particles and the like are sucked away by a draught fan; because the one-level screen cloth and the second grade screen cloth shake back and forth from top to bottom, because the density of sand grain is far greater than the density of rice, the sand grain receives the effect of gravity inertia to discharge from the granule stone export at second grade screen cloth top, and the rice then the landing flows into the hopper from the rice export to the least significant end in, and less fine sand grain then directly sees through the second grade screen cloth and falls to the bottom of the case portion and collect the back and get rid of. However, in the prior art, the feeding amount of the stone remover is difficult to control, so that in the actual use process, the feeding amount is too small, the air leakage points are more, and the stone removing efficiency is reduced; if the feeding is too big, then easily form the malt dune on the sifter, the amount of wind is unbalanced, can make the destoner lose the stone effect completely, and difficult discharge impurity causes the jam easily.
