Abstract

The invention relates to the technical field of agricultural machinery manufacturing, in particular to a rice and bran sieving system. The rice and bran sieving system comprises a feeding hopper, a first sieving mechanism and a second sieving mechanism. The first sieving mechanism is mainly composed of a first sieving box body and an air induction mechanism arranged on one side of the first sieving box body. The air induction mechanism comprises an air bellow and a fan driven by a motor. A dust outlet is formed in the lower portion of the air bellow, the air bellow is communicated with the upper portion of the first sieving box body through a pipeline, and the lower portion of the first sieving box body is communicated with the second sieving mechanism. The first sieving mechanism sieves rice and bran roughly and separates the rice and the bran through negative pressure generated by the fan, and the second sieving mechanism sieves the bran in the rice finely and separates the rice and the bran through positive pressure. The rice and bran sieving system is simple in structure and small in occupied space, and greatly improves the work efficiency of workers.

Description

Rice chaff skin screening system
Technical field
The present invention relates to manufacture of agricultural machinery technical field, relate in particular to a kind of rice chaff skin screening system.
Background technology
China produces the large agricultural country that paddy rice is master, we go chaff two procedures to complete through shelling husk rice and selection by winnowing paddy for edible rice, in general, at present, be still in vast rural area and adopt traditional husk rice that first paddy shelled to make rice, chaff mixture, concentrated again and carry out selection by winnowing and go chaff to realize the object 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 complete continuously husk rice and selection by winnowing is removed the husk rice machining processor tool of chaff two procedures, they are that the air-flow importing air compartment that the rotation of motor afterbody cooling fan is produced blows out chaff material, 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, affecting motor normally works.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, and a kind of rice chaff skin screening system is provided, simple in structure, can carry out sub-sieve to rice and chaff skin.
The present invention 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 be arranged on the draft mechanism of described the first sub-sieve casing one side, described draft mechanism comprises bellows and by motor-driven fan, described bellows bottom is provided with 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 is arranged on the secondary hopper 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 sieve.
Preferably, described fan is two.
Preferably, the angle that described sieve is 45 degree to 80 degree along the wind direction direction of fan is arranged on screen-dividing machine bottom part body.
Preferably, described screen-dividing machine main body is provided with discharge door.
The invention has the beneficial effects as follows: 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 chaff skin, the second sub-sieve mechanism is to also existing the chaff skin in rice to carry out further accurately sub-sieve, what the second sub-sieve mechanism adopted is that the mode of malleation separates, being beneficial to wind-force blows off the impurity of lighter weight, sieve is for separating cereal less particle, thereby can filter out qualified cereal, simple in structure, take up room little, greatly improved workman's operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: 1, material bin; 2, the first sub-sieve mechanism; 3, the second sub-sieve mechanism; 4, the first sub-sieve casing; 5, draft mechanism; 6, bellows; 7, fan; 8, dust mouth; 9, the second sub-sieve casing; 10, secondary hopper; 11, sieve; 12, fan.
Detailed description of the invention
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of rice chaff skin screening system, include hopper 1, the first sub-sieve mechanism 2, the second sub-sieve mechanism 3, described the first sub-sieve mechanism mainly by the first sub-sieve casing 4 and and be arranged on the draft mechanism 5 of described the first sub-sieve casing one side, draft mechanism adopts the mode of air draught by the chaff skin sucking-off from the side dropping in the first sub-sieve casing, described draft mechanism comprises bellows 6 and by motor-driven fan 7, described bellows bottom is provided with dust mouth 8, chaff skin is discharged to outside from this 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.The rice falling through the first sub-sieve casing enters into the second sub-sieve mechanism.Described the second sub-sieve mechanism comprises the second sub-sieve casing 9 and is arranged on the secondary hopper 10 on screen-dividing machine main body top, and secondary hopper bottom offers hopper port, and described hopper port bottom is provided with the sieve 11 that extends to the second sub-sieve bottom half; Fan 12 is installed on the sidewall of described screen-dividing machine main body, and the position of described fan blowing mouth is right against between hopper port and sieve.Described fan is two.The angle that described sieve is 45 degree to 80 degree along the wind direction direction of fan is arranged on screen-dividing machine bottom part body.Described screen-dividing machine main body is provided with discharge door.
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 chaff skin, the second sub-sieve mechanism is to also existing the chaff skin in rice to carry out further accurately sub-sieve, what the second sub-sieve mechanism adopted is that the mode of malleation separates, being beneficial to wind-force blows off the impurity of lighter weight, sieve is for separating cereal less particle, thereby can filter out qualified cereal, simple in structure, take up room little, greatly improved workman's operating efficiency.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
