Description

A kind of Chinese prickly ash cleaner

Technical field

The utility model belongs to feed separation machinery technical field, relates to a kind of Chinese prickly ash cleaner.

Background technology

At present, cleaning of Chinese prickly ash substantially still adopted traditional artificial screening method, its main process is that the Chinese prickly ash gradation of first airing being done screens out wild pepper seed and granule foreign material, by repeatedly rubbing green pepper barre and Chinese prickly ash is broken away from again, and then the green pepper barre of winnowing with a dustpan; Meanwhile, also to carefully pick large granular impurity, such as soil block, stone etc.Above-mentionedly clean method not only labour intensity be large, and time-consuming, take a lot of work, efficient is also extremely low, has been difficult to adapt to current market to the requirement of Chinese prickly ash quantity and degree of purity.In the prior art, once attempted adopting the common main cleaner that is formed by feed hopper, sheller unit and vibration screen that Chinese prickly ash is screened by the people, but because above-mentioned type does not structurally take into full account Chinese prickly ash, its Ex-all rate is only about 80%, so also be difficult to promote the use of.

The utility model content

The purpose of this utility model is to overcome the deficiency that prior art exists, and then a kind of rational in infrastructure, easy to use and Chinese prickly ash cleaner with high production rate and Ex-all rate is provided.

The technical solution that adopts for achieving the above object is such: the Chinese prickly ash cleaner that provides comprises frame, feed hopper, be positioned at feed hopper bottom sheller unit, be positioned at screen cloth and the screen cloth vibrating mechanism of feed hopper outlet below, on said screen cloth is served as reasons, in, lower three-layer network plate is pressed the inclination screen cloth that Z-shaped is arranged, wherein, the grid aperture of upper strata screen cloth and middle level screen cloth is a bit larger tham respectively and less than the particle diameter of Chinese prickly ash particle, lower screen is slit hole shape screen cloth, be equipped with the sieving guide groove below every layer of screen cloth, the sieving guide groove of upper strata screen cloth leads to the initiating terminal of middle level screen cloth, the sieving guide groove of middle level screen cloth leads to the frame outside, said screen cloth vibrating mechanism is crank connecting, wherein connecting rod and screen cloth are hinged, the screen cloth two ends are hinged on the rocking bar, the other end of rocking bar is hinged on the frame, said sheller unit is comprised of finger-like grain threshing roller and the plectane semicircle with holes that is centered around the grain threshing roller Lower Half, and grain threshing roller is comprised of roll shaft and the finger bar that is fixed on the roll shaft.

Technical solution of the present utility model also is: the middle level screen cloth in the mesh structure is by the circle hole shape main screen and be positioned at slit hole shape secondary screen below the main screen) form.

Technical solution of the present utility model also is: the screen cloth vibrating mechanism has two crank connecting, and their connecting rod is hinged with middle level screen cloth and lower screen respectively.

In the course of work, the Chinese prickly ash particle that is entered by feed hopper will be first by separating than bigger material behind the screen cloth of upper strata, after by the middle level screen cloth with the Chinese prickly ash particle with wild pepper seed and separate than small impurities, and then further the green pepper barre is separated by lower screen, finally namely obtain pure Chinese prickly ash particle.

Compared with prior art, the utility model has the advantages that and respectively Chinese prickly ash particle, wild pepper seed and foreign material to be separated, owing to adopted three layers of mesh structure that tilt and be provided with the sieving guide groove, the traveling distance of selected Chinese prickly ash is increased, thereby the Ex-all effect is fine, through designer's test, the Ex-all rate of this Chinese prickly ash machine can reach more than 98%.
