Abstract

The utility model relates to a separator. The utility model is used for separating grass and grain, and is especially used for paper mills to separate leftovers of cutting grass. The utility model is composed of a support frame, an electric motor, and an eccentric wheel. An upper sieve is fixed on the upper part of a lower sieve. The eccentric wheel drives the lower sieve through a connecting rod to do reciprocating linear motion, and the utility model realizes the separation of grass, dust, chaff, and rice kernel. The chaff and the rice kernel backwards slide along the lower sieve and falls into an air barrel which is arranged on the back end of a support frame. Under the action of the fan, the separation of the chaff and the rice kernel is realized. If a paper mill produces paper of thirty thousand per year, the rice kernel of 30 tons is separated from the leftovers of cutting grass.

Description

A kind of careless grain seperator

The utility model is a kind of careless grain separation that is used for, especially for the seperator of papermaking spent of cutting grass separation.

The most of paper mill of China all is to be raw material with the rice wheat straw, in the chaffcutter process, can produce some leftover bits and pieces, and many rice wheats and some available rice wheat straws are wherein arranged, and has not just caused waste if do not reclaim.At present, many separating cleaning machineries are arranged, but mostly be used for cleaning of grain, and be not suitable for the separation of careless grain.

It is a kind of simple in structure that the purpose of this utility model is to provide, and works continuously, and careless grain can be carried out the seperator of grass, chaff, grain, dust separation.

For achieving the above object, the utility model has been taked following proposal: top sieve and following sieve are housed on support simultaneously, and two sieves are fixed together.The sieve aperture of top sieve can leak down chaff, rice wheat and dust, and the sieve aperture of the sieve dust that can only leak down down.Following sieve is by four rotatable pulley support in chute, and drives by the eccentric wheel that connecting rod is fixed on the support front end and to do reciprocating linear motion.The high rear end of chute front end is low.In the rear end of support fan and air duct are housed, are used for separating chaff and rice wheat.During work, spent of cutting grass is put into top sieve, under upper and lower sieve reciprocating motion effect, dust, chaff, rice wheat drop on down above the sieve by the top sieve sieve aperture, and long rice wheat straw constantly slides backward along top sieve, skid off from grass outlet at last and fall, dust again by under sieve aperture drop on the ground, chaff and rice wheat slide backward and fall into funnel along sieve down, under the fan effect, chaff is blown the air duct mouth, and the rice wheat falls into three mouths of putting out cereal of air duct bottom.

The utility model realized the separation of grass, dust, chaff and rice wheat owing to taked the structure of upper and lower sieve different-diameter sieve aperture because returning apparatus fan and air duct, realized separating of chaff and rice wheat again.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Accompanying drawing is the separator structure schematic diagram.

Support (9) is welded into angle steel, loads onto motor (10) in its front end bottom.At the top of motor (10) dress eccentric wheel (12), the axis of eccentric wheel (12) is positioned at the plane of movement of pulley (2) axis.Motor (10) drives eccentric wheel (12) by V-belt (11) and rotates.Chute (14) is tied with channel-section steel and support (9) weldering.Top sieve (1) and following sieve (3) are fixed as one, and load onto four pulleys (2), push then in the chute (14) at following sieve (3) dual-side.With connecting rod (13) eccentric wheel (12) and following sieve (3) are coupled together, make rotatablely moving of eccentric wheel (12) become the linear reciprocating motion of sieve (3) down.Load onto fan (8) and the air duct (5) that is welded into steel plate in the rear end of support (9), be welded with funnel (4), have three put out cereal mouthful (7) in air duct (5) bottom in an end top of the close fan (8) of air duct (5).

Claims

A kind of careless grain seperator, by support (9), motor (10), V-belt (11) eccentric wheel (12) is formed, it is characterized in that top sieve (1) is fixed on down above the sieve (3), the sieve aperture of top sieve (1) dust that can leak down, chaff, the rice wheat, the sieve aperture of following sieve (3) dust that can only leak down, top sieve (1) side, rear end has grass outlet (15), following sieve (3) is supported by four pulleys (2) that roll in chute (14), eccentric wheel (12) drives down by connecting rod (13), and sieve (3) does reciprocating linear motion, the high rear end of chute (14) front end is low, fan (8) and air duct (5) are contained in the rear end of support (9), have funnel (4) at air duct (5) near weldering above the end of fan, chaff and rice wheat that following sieve (3) rear end skids off fall into funnel (4), and air duct (5) bottom has three put out cereal mouthful (7).
