Description
Technical field
The present invention relates to the impurity removing technology of cereal, be specifically related to a kind of cereal three grades of cleaning plants.
Background technology
According to the difference of cereal and impurity aerodynamic property, the method utilizing air-flow to carry out being separated is called selection by winnowing.For the pneumatic separator of cereal cleaning, be divided into outer suction and circulating by the processing mode of dust laden air, be divided into by gas pressure and blow formula and suction, be divided into rectilinear and horizontal etc. by air motion direction.The light breeze screening device of existing a kind of cereal, its primary structure comprises feeding cylinder, the first suction channel be communicated with feeding cylinder, is positioned at the first suction channel side direction and the first expansion chamber be communicated with the first suction channel, the second expansion chamber is provided with in the side direction of the first expansion chamber, the cross-sectional area of the first expansion chamber and the second expansion chamber is greater than the area of the first suction channel and the second suction channel, be provided with the second suction channel be communicated with the second expansion chamber at the second expansion chamber, be wherein equipped with impurity collecting box in the below of the first expansion chamber and the second expansion chamber.During work, cereal enters in the first suction channel via feeding cylinder, selection by winnowing is carried out with the air flow contacts in the first suction channel, impurity enters the first expansion chamber along with air-flow, because the cross-sectional area of expansion chamber is large, air velocity declines suddenly, and therefore impurity can sedimentation fall into impurity collecting box in the first expansion chamber, and the cereal through first time removal of impurities sends into the second suction channel removal of impurities by artificial again.
Above-mentioned cereal light breeze screening device Problems existing is: 1. after the cereal of first time removal of impurities is collected, need to carry out secondary removal of impurities by artificial second suction channel of sending into again, troublesome poeration, efficiency is low, and by means of only selection by winnowing, usually can only the lighter impurity of clear quality, the impurity larger for quality still can mix with cereal; 2. the cross-sectional area of expansion chamber cannot regulate, thus cannot select the expansion chamber of suitable cross-sectional area according to the particle size difference of impurity; 3. the adjustment of the outlet size of expansion chamber and the adjustment of air outlet size are all that control valve by arranging separately realizes, complex structure, and cost is high and regulate inconvenience.
Summary of the invention

Cereal in this programme three grades of cleaning plants, comprise feeding cylinder, be positioned at first suction channel be communicated with feeding cylinder bottom of feeding cylinder side direction, be positioned at the first expansion chamber of the first suction channel side direction, be positioned at the second expansion chamber of the first expansion chamber side direction and be positioned at the second suction channel of the second expansion chamber side direction, feeding cylinder bottom has discharging opening, the cross-sectional area of the first expansion chamber is greater than the cross-sectional area of the first suction channel, the cross-sectional area of the second expansion chamber is greater than the cross-sectional area of the second suction channel, impurity collector is equipped with in the below of the first expansion chamber and the second expansion chamber, the bottom of the first expansion chamber and the second expansion chamber is equipped with air inlet, the top of the first expansion chamber and the second expansion chamber all has air outlet, the inwall of discharge outlet is hinged with downward-sloping gravity door, the sidewall of feeding cylinder is equipped with the push rod of level, the end of push rod have with gravity door bottom the push rod inclined-plane that offsets, push rod and a montant one-body molded, the piston rod of described montant and a cylinder is fixed, the sieve nest to the second suction channel lopsidedness is provided with between montant and the second suction channel, sieve nest one end is hinged on the bottom of montant, the other end of sieve nest is hinged on the sidewall of the second suction channel, the sidewall of the second suction channel is positioned at sieve nest and the second suction channel hinged place has secondary feeds mouth, described sieve nest is right against the opening of the first suction channel bottom.
The advantage of this programme is: 1. time the cereal in feeding cylinder is piled up a certain amount of, the piston rod of cylinder drives montant to retreat, montant drives push rod and sieve nest to retreat, because gravity door is hinged with the inwall of material feeding box, therefore gravity door will be opened, cereal enters in the first suction channel and carries out a selection by winnowing, when the piston rod of cylinder drives push rod to close gravity door, move driving sieve nest simultaneously to the second suction channel direction, cereal on sieve nest is delivered into the second suction channel, in course of conveying, removing is large assorted simultaneously, the mode that this programme adopts gravity door and sieve nest to link, sieve nest and push rod adopt the same power source, enormously simplify the structure of whole device, save cost.2. this programme adopts three grades of modes of cleaning, and that greatly can improve cereal cleans quality, can remove mixing greatly in cereal efficiently particularly by sieve nest.
Further, be provided with impurity collecting box in the bottom of sieve nest, the top of impurity collecting box has into Za Kou, and the both sides entering assorted mouth have limiting plate, and sieve nest is between two limiting plates.Two limiting plates play the effect of motion guide to it when sieve nest moves.
Further, sieve nest is pawl sieve.By the effect of pawl, when being conducive to shaker vibration, be fed forward cereal.
Further, first expansion chamber and the baffle for separating of the second expansion chamber by vertically moving up and down, the first frustum is respectively equipped with in the both sides of dividing plate, two sidewalls that first expansion chamber is relative with the second expansion chamber include riser and are supported on the swash plate on riser top, the upper surface of swash plate has the swash plate inclined-plane matched with the first frustum tapering, and swash plate inclined-plane and the first frustum offset.By regulating dividing plate, dividing plate being moved up and down the swash plate in the first expansion chamber and the second expansion chamber just can be forced to move obliquely or obliquely, thus change the cross-sectional area of the first expansion chamber and the second expansion chamber, to adapt to the sedimentation of different size impurity.
