Abstract

The utility model discloses a buffer type grain cleaning sieve which comprises a base, wherein a sieving box is installed on the base through a spring group, a vibrating sieve is installed in the sieving box, a row of linked rotating shafts which are arranged at equal intervals are installed above the vibrating sieve in the sieving box, material blocking rubber rollers of which the sections are elliptic are installed on the rotating shafts, the material blocking rubber rollers on the adjacent rotating shafts can be abutted to achieve a blocking effect in the process of operation along with the rotating shafts, and a material guiding shallow slot array is distributed on the material blocking rubber rollers. The buffer type grain cleaning sieve has the advantages of simple and reasonable structure and convenience in installation and use, the design that the material blocking rubber rollers are arranged above the vibrating sieve is adopted, so that grains can gradually fall into the vibrating sieve when the grains enter the sieving box, so as to prevent the vibrating sieve from being impacted and damaged, the service life of the vibrating sieve is effectively prolonged, and the safe operation and the sieving efficiency of the cleaning sieve are guaranteed.

Description

A kind of buffer-type grain cleaning sieve

Technical field

The utility model relates to grain processing field, is specially a kind of buffer-type grain cleaning sieve.

Background technology

In the process of grain, need to use sieve materials device to sieve processing to grain, to remove the foreign material particle being mixed with in grain.And existing sieve materials device structure is reasonable not, stability is not good, after a large amount of grain falls into screen box, accumulates on vibratory sieve, easily vibratory sieve is impacted, and causes vibratory sieve deformed damaged, the lost of life, and what impact sieve material operated normally carries out.

Utility model content

The purpose of this utility model is to provide a kind of buffer-type grain cleaning sieve, reasonable not to solve sieve materials device structure traditional in prior art, stability is not good, after falling into screen box, a large amount of grain accumulates on vibratory sieve, easily vibratory sieve is impacted, cause vibratory sieve deformed damaged, the lost of life, the problem that the operation of impact sieve material is normally carried out.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of buffer-type grain cleaning sieve, it is characterized in that: include base, on described base, by groups of springs, screen box is installed, in described screen box, vibratory sieve is installed, the inherent vibratory sieve of described screen box top is provided with the rotating shaft of the interlock of row's spaced set, the backgauge rubber roll of cross section ovalize is installed in described rotating shaft, and the backgauge rubber roll in adjacent shafts can offset to play barrier effect in rotating shaft operation process, on described backgauge rubber roll, be distributed with guide shallow slot array.

Described a kind of buffer-type grain cleaning sieve, is characterized in that: described rotating shaft drives by reducing motor.

The beneficial effects of the utility model are:

The utility model is simple and reasonable, easy to install, employing arranges the design of backgauge rubber roll above vibratory sieve, make grain can fall into vibratory sieve by component when entering screen box, prevent vibratory sieve to impact damage, effectively extend the service life of vibratory sieve, guaranteed safe operation and the sieve material efficiency of cleaning sieve.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of buffer-type grain cleaning sieve, include base 1, on base 1, by groups of springs 2, screen box 3 is installed, vibratory sieve 4 is installed in screen box 3, and the inherent vibratory sieve of screen box 34 tops are provided with the rotating shaft 5 of the interlock of row's spaced set, and the backgauge rubber roll 6 of cross section ovalize is installed in rotating shaft 5, and the backgauge rubber roll 6 in adjacent shafts 5 can offset to play barrier effect in rotating shaft 5 operation process, on backgauge rubber roll 6, be distributed with guide shallow slot array 7.

Rotating shaft 5 drives by reducing motor.
