Abstract
The utility model relates to the technical field of agricultural machine manufacture, in particular to a system for separating and screening rice and husks. The system for separating and screening the rice and the husks comprises a receiving hopper, a first separating and screening mechanism and a second separating and screening mechanism. The first separating and screening mechanism is mainly composed of a first separating and screening box body and an induced air mechanism which is arranged on one side of the first separating and screening box body. The induced air mechanism comprises an air box and a fan which is driven by a motor, a dust outlet is formed in the lower portion of the air box, the air box is communicated with the upper portion of the first separating and screening box body through a pipeline, and the lower portion of the first separating and screening box body is communicated with the second separating and screening mechanism. The rice and the husks are coarsely separated and screened by the first separating and screening mechanism, negative pressure generated by the fan is utilized by the first separating mechanism to separate the rice and the husks, the husks still existing in the rice are further accurately separated and screened by the second separating and screening mechanism, and the second separating and screening mechanism conducts separation in the positive pressure mode. The system for separating and screening the rice and the husks is simple in structure, little in occupied space, and capable of greatly improving working efficiency of workers.
Description
Technical field
The utility model relates to the manufacture of agricultural machinery technical field, relates in particular to a kind of rice chaff skin screening system.
Background technology
China produces the large agricultural country that paddy rice is the master, the rice that we eat goes the chaff two procedures to finish through shelling husk rice and selection by winnowing paddy, in general, at present, be still the traditional husk rice that first paddy shelled of employing in vast rural area and make rice, the chaff mixture, again it is concentrated and carry out selection by winnowing and go chaff to realize the purpose of selected dog rice, this traditional operating type work efficiency is low, labour intensity is large, far be not suitable with the requirement of mechanization of agriculture, recently release some and can simultaneously finish continuously husk rice and selection by winnowing is removed the husk rice machining processor tool of chaff two procedures, they are the air-flow that the rotation of motor afterbody cooling fan produces to be imported air compartment the chaff material is blown out, although this husk rice processing equipment practical husk rice of energy and selection by winnowing are blown sugar and are worked continuously, but this mode has been disperseed the cooling air quantity of motor, reduce the normal cooling heat dissipation performance of motor, affected the motor normal operation.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of rice chaff skin screening system is provided, and is simple in structure, can carry out sub-sieve to rice and chaff skin.
The utility model for achieving the above object, by the following technical solutions:
A kind of rice chaff skin screening system, it is characterized in that: include hopper, the first sub-sieve mechanism, the second sub-sieve mechanism, described the first sub-sieve mechanism mainly by the first sub-sieve casing and and the draft mechanism that is arranged on described the first sub-sieve casing one side, described draft mechanism comprises bellows and by motor-driven fan, described bellows bottom is provided with the dust mouth, described bellows are communicated with described the first sub-sieve casing top by pipeline, the bottom of described the first sub-sieve casing and described the second sub-sieve mechanism connection.
Preferably, described the second sub-sieve mechanism comprises the second sub-sieve casing and the secondary hopper that is arranged on screen-dividing machine main body top, and secondary hopper bottom offers hopper port, and described hopper port bottom is provided with the sieve that extends to the second sub-sieve bottom half; On the sidewall of described screen-dividing machine main body fan is installed, the position of described fan blowing mouth is right against between hopper port and the sieve.
Preferably, described fan is two.
Preferably, described sieve is 45 degree to the angles of 80 degree along the wind direction direction of fan and is installed in the screen-dividing machine bottom part body.
Preferably, described screen-dividing machine main body is provided with discharge door.
The beneficial effects of the utility model are: the first sub-sieve mechanism carries out rough sub-sieve to rice and chaff skin, the first sub-sieve mechanism utilizes the negative pressure of the generation of fan that rice is separated with the chaff skin, the second sub-sieve mechanism is to also existing the chaff skin in the rice to carry out further accurately sub-sieve, the second sub-sieve mechanism adopts is that the mode of malleation is separated, being beneficial to wind-force blows off the impurity of lighter weight, sieve is used for the cereal that particle is less and separates, thereby can filter out qualified cereal, simple in structure, it is little to take up room, and has greatly improved workman's operating efficiency.
