Abstract

The utility model discloses a screening machine for grains with sundries, suitable to clear granular grains mixed with stems, leaves and other sundries, comprising a shell arranged on a frame, a roller screen, which rotates due to motor drive, arranged in the shell, a feeding opening arranged at the front end of the roller screen, a sundries discharge opening arranged at the back end of the roller screen, a dust storage fixedly arranged under the roller screen. The utility model has the advantages of increasing production efficiency by 4 to 5 times than common flat-bottom screen when screening the sundries, reducing labor intensity due to mechanical material feeding, low energy consumption, low mechanical faults, screening clearly and uneasy to block the screen holes, low noise, no dust pollution and other advantages.

Description

Grain foreign material scavenger

Technical field

The utility model relates to a kind of grain foreign material scavenger, and the screening of the foreign material such as stem, leaf that mix in the particularly suitable particle grain is removed.

Background technology

At present, grains such as peasant's harvesting corn, paddy, soybean, perhaps the buyer agent the purchase and silo at aspects such as stored grain, all need the screening as foreign material such as stem, leaves that is entrained in the grain is removed, mostly the current screening plant that adopts is plansifter, promptly is that flat sieve simply is housed on framework, is directly driven by driving motor and separates screening, it exists following deficiency: the one, and production efficiency is low, removes output only about 5 tons/hour; The 2nd, adopt artificial feeding, and in reset procedure, easily stifled sieve aperture or stifled after need artificial treatment, labour intensity is big; The 3rd, power consumption is high, mechanical accident rate height; The 4th, grain and foreign material separation screening are unclean, and simultaneously big the and dust of using time tool noise flies upward, so contaminated environment not only, and it is unfavorable also can to cause health of human body.

Utility model content the purpose of this utility model is exactly for solving the above problems, for people provide a kind of grain foreign material scavenger, it can increase work efficiency, mechanical accident is few, pollute the foreign material screening is removed.

The purpose of this utility model is to realize by following technical measures:

Comprise framework, rotary screen, motor composition, housing is housed on framework, inside and outside rotary screen is housed in the housing, this rotary screen one end is contained in framework one side, and an end is contained in the framework opposite side, is rotated by the motor transmission, at inside and outside rotary screen front end charging aperture is arranged, rear end discharging place has discharging opening to be contained on the framework, and air blast is connected discharging opening, is fixed with dust storehouse below inside and outside rotary screen.

Described inside and outside rotary screen is spaced apart bilayer and is integral, and an end activity is contained on the scroll wheel, and this scroll wheel is contained in support and is fixed on framework one side, and the other end connects decelerator and motor is fixed on the framework opposite side support.The rotary screen sieve aperture is square in described, and outer rotary screen sieve aperture is rectangle or circular hole.

Described framework bottom is equipped with and is moved wheel, and front end moves wheel turning-bar is housed.

Described discharging opening is made of interior rotary screen impurity outlet, outer rotary screen discharging opening and is contained on the framework, rotary screen impurity outlet in rotary screen discharging is communicated with in it, and outer rotary screen discharging is communicated with outer rotary screen discharging opening, the outer rotary screen discharging opening of air blast connection.

Advantage of the present utility model owing to adopt rotary screen screening grain, foreign material to separate, has improved production efficiency, improves 4-5 than the now doubly, handles approximately more than 20 tons/hour; Adopt mechanical feed, reduce labour intensity; Adopt the electrical motor gearshift transmission that cylinder is rotated, consume energy low, mechanical accident is low; Adopt the double-deck screening of inside and outside rotary screen, the clean difficult stifled sieve aperture of screening, the little contamination by dust of noise is little etc.

Description of drawings

Below with reference to accompanying drawing the utility model embodiment is elaborated:

Fig. 1 is the main schematic diagram of looking of the utility model assembling.

Fig. 2 is that schematic diagram is looked on the utility model left side.

Fig. 3 is that schematic diagram is looked on the utility model right side.

The specific embodiment

Shown in Fig. 1-3, the utility model comprises framework (13), rotary screen (3), (4), motor (6) composition.The closure casing (2) of ∩ type is housed on framework (13), in being equipped with in the housing (2), outer rotary screen (4), (3), this rotary screen compass screen surface is spaced apart bilayer and is integral, one end activity is contained on the scroll wheel (14), scroll wheel (14) is contained in support and is fixed on framework (13) one sides, the other end connects decelerator (5) and motor (6) is fixed on framework (13) the opposite side support, in motor (6) transmission, outer rotary screen (4), (3) rotate, interior rotary screen (4) sieve aperture is square, outer rolling sieve (3) sieve aperture is rectangle or circular hole, interior, outer rolling sieve (4), (3) front end has charging aperture (1), be fixed on the housing (2), rear end discharging place has discharging opening (8) to be contained on the framework (13), discharging opening (8) is made of interior rotary screen impurity outlet (7) and outer rotary screen discharging opening (9), rotary screen impurity outlet (7) in rotary screen (4) discharging is communicated with in it, outer rotary screen (3) discharging is communicated with outer rotary screen discharging opening (9), air blast (10) is communicated with outer rotary screen discharging opening (9), interior, outer rotary screen (4), (3) be fixed with dust storehouse (12) below.

During work, in motor (6) drive, outer rotary screen (4), (3) rotate, add the doping stem at charging aperture (1), the hybrid particles grain of foreign material such as leaf enters interior rotary screen (4), bigger stem, rotary screen impurity outlet (7) was discharged in leaf entered, particle grain and less stem, rotary screen (3) postsearch screening outside the sieve aperture of foreign material such as leaf and dust on interior rotary screen (4) gone into, the sieve aperture of dust on outer rotary screen (3) falls into dust storehouse (12), particle grain and less stem, leaf enters outer rotary screen discharging opening (9), dry by air blast (10), less stem, leaf is discharged by secondary impurity discharging port (9-1), and particle grain reclaims through clean grain mouth (9-2).
