Abstract

The utility model relates to a small grain and chaff separator which comprises an oblique grain and chaff separating chamber from an inputting end to an outputting end which is oblique toward slanting upside, wherein a sieve plate and a leaf blade wheel are fixed in an inner cavity of the grain and chaff separating chamber. The leaf blade wheel is located on the outputting end. The inputting end of the grain and chaff separating chamber is connected with a mixing grain entering pipe. The wall of a lower chamber of the grain and chaff separating chamber is connected with a clean grain granary and a clean grain pipe inlet which is located in the clean grain granary. The lower side of the clean grain granary is provided with a clean grain outlet. The outputting end of the grain and chaff separating chamber is communicated with a blower. The grain and chaff separator can separate the chaff from the grain and is application to peasant households.

Description

Small-sized grain chaff seperator

Technical field

The utility model relates to the device that grain grain is separated with the shell chaff.

Background technology

After cereal crops were received and beat, normally grain grain and shell chaff were mixed in together, can not put in storage, it must be separated, with the method that grain grain separates with the shell chaff, large-scale farm is to use winnowing machine, with winnowing machine grain grain is separated with the shell chaff, though the efficient height, complex structure, cost height are not suitable for each peasant household and use; Each peasant household method commonly used is with original tools such as dustpan, sieve and brooms, rain not had, there is the not too big not too little again weather of wind and wind-force to descend to carry out operation, its weak point be take a lot of work, labour intensity is big, efficient is low, it is unclean to separate, and restricted by weather conditions.

Summary of the invention

The purpose of this utility model provides a kind of small-sized grain chaff seperator that each peasant household uses that is fit to.

This small-sized grain chaff seperator, comprise the grain chaff separation chamber that tilts obliquely upward from input to output, be connected with sieve plate and blade wheel in the inner chamber of grain chaff separation chamber, the blade wheel is positioned at the output position, the input of grain chaff separation chamber is connected to mixed grain and goes into pipe, connect a clean silo and be provided with the clean grain that is positioned at clean silo on the following locular wall of grain chaff separation chamber and go into the mouth of pipe, a clean grain outlet is arranged at the bottom of clean silo, and the output of grain chaff separation chamber is communicated with blower fan.

As improvement to this small-sized grain chaff seperator, between the input of the output of grain chaff separation chamber and blower fan, also be connected to gas chaff separation chamber, one mouth of pipe of giving vent to anger that stretches out from end face is housed in the inner chamber of gas chaff separation chamber, one air inlet is arranged at the give vent to anger tube wall bottom of the mouth of pipe, the give vent to anger lower end affixed of the mouth of pipe is the end plug of truncated cone-shaped, the lower end of gas chaff separation chamber is connected with the chaff storehouse, between the end face in chaff storehouse and the bottom surface of end plug a narrow annular channel is arranged, and the bottom in chaff storehouse is provided with chaff discharging port.

The above-mentioned grain chaff separation chamber and the angle of inclination of horizontal plane are 15 °-35 °.

The width of above-mentioned slit is 2-2.5cm.

During work, connect fan power earlier, mixing has the grain of shell chaff grain promptly to mix grain to go into pipe and be inhaled into a chaff separation chamber inner chamber through mixing grain, because the proportion of grain grain is greater than the proportion of shell chaff, thereby shell chaff direction output on grain grain flows, grain grain overwhelming majority in process of flowing falls into the medium position place, bottom surface of a chaff separation chamber through the eyelet of sieve plate, because grain chaff separation chamber is the output height, input is low, one angle of inclination is arranged, so the grain grain that falls on the bottom surface, chaff separation chamber is slided and is rolled, going into the mouth of pipe through clean grain falls in the clean silo, the minority grain grain that does not fall on the bottom surface, chaff separation chamber continues to move ahead in company with the shell chaff, under the eddy current effect that the blade wheel that rotatablely moves is produced, lived by leaf baffle, and drive the medium position place, bottom surface enter a chaff separation chamber by blade, sliding rolling after clean grain is gone into the mouth of pipe falls in the clean silo; Because of the shell chaff is light, under the swabbing action of blower fan,, discharge through blower fan from the output sucking-off of grain chaff separation chamber.

In order to purify the air that blower fan is discharged, prevent that the shell chaff from flying upward everywhere, shell chaff from the output sucking-off of grain chaff separation chamber, enter gas chaff separation chamber in company with air-flow from the arrival end of gas chaff separation chamber, under the stopping of the suction of blower fan and locular wall, form vortex, the shell chaff falls, enters the chaff storehouse through narrow annular channel along locular wall, and clean air enters the mouth of pipe of giving vent to anger from air inlet, discharges through tube connector, blower fan again.

Describe by the above-mentioned course of work, this small-sized grain chaff seperator not only can be separated the shell chaff that is mingled in the grain, with original tools such as usefulness dustpan, sieve and brooms, rain not had, there is the not too big not too little again weather of wind and wind-force to descend to carry out operation, the separation of shell chaff is compared, have characteristics convenient, fast, that efficient is high, labour intensity is little, and simple in structure, cost is low, is applicable to that each peasant household uses.

Description of drawings
