Abstract
The utility model discloses an efficient and environment-friendly drum type pre-cleaner. A traditional drum type pre-cleaner has the disadvantage that after cleaning, a large amount of soil dust, broken ears of wheat, glume, whiskers and the like are still contained in grains frequently. The efficient and environment-friendly drum type pre-cleaner comprises a frame (1); a roller screen (4) is mounted in the upper part at the rear end of the frame; the inclination angle of the roller screen is 6-8 degrees; the roller screen is connected with a food feeding hopper (5); two small impurity removal funnels (7) are arranged below the roller screen, and are connected with the frame; two riding wheels (14) supporting the roller screen to rotate are mounted at the rear end of the roller screen; the front end of the roller screen is connected with a gearing-down mechanism (3) through a universal cross coupling; an impurity runner or a feeding box or a vibration board (8) is mounted on the frame below the front end of the roller screen; a dust removal chamber (9) is mounted on the frame in front of the impurity runner or the feeding box or the vibration board (8); a triple cyclone dust collector (11) and a fan (10) are mounted at the front end of the frame. The efficient and environment-friendly drum type pre-cleaner is used for pre-cleaning food.
Description
technical field:
the utility model relates to a kind of efficient and environment-friendly type cylindrical pre-cleaning screen.
background technology:
cylindrical pre-cleaning screen is applicable to gather in the crops the cleaning of the cereal such as rear corn, wheat, paddy rice, soybean.Can meet warehouse-in raw grain quality requirement.Also can be used for the initial cleaning of other industry granule materials.Its feature: stable drive, noise is little, consumes energy low, and treating capacity is large, and good impurity removing effect is durable in use, is convenient to adjust and safeguard.But it is large to have treating capacity just because of it, blower fan often heavy at grain, grain layer is blocked up with regard to difficulty or ease, blows through, grain amount is few, layer is thin, is easy to again grain to blow away.Often cereal still contains and measures greatly native dust, disconnected fringe, clever shell, whisker etc., and must enter secondary, cleans.
utility model content:
the purpose of this utility model is to provide a kind of efficient and environment-friendly type cylindrical pre-cleaning screen.
above-mentioned object realizes by following technical scheme:
a kind of efficient and environment-friendly type cylindrical pre-cleaning screen, its composition comprises: frame, roller screen is arranged in described frame rear end top, described roller screen inclination 6-8 degree, described roller screen is connected with grain feeding bucket, below described roller screen, there are two little assorted funnels, described little assorted funnel is connected with described frame, the rear end of described roller screen is provided with two support rollers that support its rotation, the front end of described roller screen is connected by universal cross coupler with reduction gearing mechanism, in the frame of described roller screen front end below, impurity chute or box for feeding odd or oscillating plate are installed, on described impurity chute or the front methods, rack of box for feeding odd or oscillating plate, dirt pocket is installed, front end in described frame is provided with three cyclone dust collectors, blower fan.
described efficient and environment-friendly type cylindrical pre-cleaning screen, roller screen canopy lid is installed on the upper methods, rack of described roller screen, described dirt pocket is connected with three described cyclone dust collectors, described blower fan respectively, at described frame lower front end, road wheel is installed, in described frame lower rear end, guide wheel is installed, at described frame front, electric cabinet is installed, described electric cabinet is connected by cable with three described cyclone dust collectors, described blower fan, described reduction gearing mechanism respectively, described reduction gearing mechanism be arranged in described frame.
beneficial effect:
1. because the utility model has been installed box for feeding odd or oscillating plate, can grain lay is even, by dust arrester large area, collect impurity again, with wind cooled cylindrical pre-cleaning screen in the past, compare, greatly improved the cleanliness of cylindrical pre-cleaning screen effect and grain, win and make a good working environment simultaneously, be specially adapted to grain specialist, grain depot, seed processing factory, and grain processing plant.
2. when this efficient and environment-friendly type cylindrical pre-cleaning screen is cleaned, grain is through conveying devices such as ribbon conveyer or spiral-pokers, grain is sent into grain feeding bucket and flow into shaft screen in roller screen, at the uniform velocity mobile in compass screen surface of grain, and cleaned continuously by the rotation of screen drum, the wherein contained large impurity that is greater than sieve aperture and the grain grain that is less than mesh size, small impurities is isolated incoming flow, large impurity flows out at the front end of interior roller screen, fall into the indoor or impurity chute of box for feeding odd or delivery sheet upper forepart impurity, and be less than the grain grain of interior mesh size, small impurities drops on outer roller screen, in roller screen, continue outside separated, be greater than the grain grain of outer mesh size, small impurities flows to roller screen front end and enters box for feeding odd or oscillating plate rear end, and the little grain grain, grain chip, the small impurities that are less than outer mesh size fall in little assorted funnel inflow bag, fall into large impurity and the grain grain of box for feeding odd or oscillating plate, under the vibration of box for feeding odd or oscillating plate, equably grain grain is sent in dirt pocket, at the front end of interior roller screen, flow out the large impurity that falls into box for feeding odd top and flow out from outlet, or the large impurity that falls into chute relies on gravity flow to discharge, enter cereal in dirt pocket under the effect of blower fan, the scored agains such as the straw of not separating in grain, dust, whisker, light clever shell, grain chip from, improved the cleanliness of grain, the straw of separating, dust, whisker, light clever shell, grain chip etc. flow in three cyclone dust collectors along air-flow, in cyclone dust collectors effect, sink to landing in screw feeder, by the rotation of screw feeder blade, impurity are discharged.
