The horizontal fan is arranged on the frame at the lower side of the rolling tube. The power is connected with an engine from the rolling tube, and the rolling tube drives the fan by a belt wheel. The hay can move radically around the axle of the rolling tube under the effect of a guide board in the lid of the rolling tube. The threshing performance and the work efficiency is high, which can realize hay, grain and chaff three separation, the separation performance is good the cleaning rate is high.
Description
The utility model relates to the thresher in a kind of farm machinery, particularly a kind of horizontal small axial-flow thresher.
Present small-sized thresher can only separate millet straw after the threshing, and can't separate a large amount of clever shell that is produced in the threshing course with grain.Also promptly, millet straw, grain, clever shell can not be carried out three separation.A large amount of clever shell and grain are mixed in together, need it could be separated by the way of manually winnowing.And the workload of winnowing is very big, and labour intensity is heavy, and this work simultaneously also must have certain experience just can finish.So during a thresher job, need usually to cooperate about five people and just can finish.Therefore, according to above present situation, be badly in need of a kind of easy to operate, efficient is high, can realize millet straw, grain, three separation of clever shell, and can be at the small-sized thresher of field operation.
The technical solution of the utility model is mainly to be made up of frame, cylinder, concave grate and blower fan.Be fixed with spiral case, feed hopper and drum cover on the frame, spiral case is provided with grass outlet, and spiral case covers in the left-hand end of cylinder; Feed hopper is located at the right side of cylinder and is joined with concave grate; The drum cover inboard is provided with and can makes the guide plate of millet straw with the drum shaft axially-movable, and drum cover is located at the outer upside of cylinder.Concave grate is located at the outer downside of cylinder and is fixed on the frame.Cylinder mainly is made of drum shaft, cylinder gripper shoe and spike-tooth, cylinder by the bearings on the drum shaft on frame.Blower fan is located at the downside of frame, and is fixed on the frame by its bearing block, and the axle head of blower fan is provided with driving pulley.Be respectively equipped with belt pulley on the two ends of drum shaft, the belt pulley of one end can external motor, and the belt pulley of the other end and the belt pulley of blower fan are by belt driving coupling mutually.Power is by the external motor of cylinder, and drives blower fan by cylinder by belt pulley again.
The spiral case housing of the inner top side of grass outlet is provided with and can stops the reflux careless baffle plate that returns of cylinder into of millet straw.
The spiral case in the grass outlet outside be provided with can make millet straw become certain orientation go out to disembark body, curved shape go out careless deflector.
Feed hopper and frame link by bolt, and the height activity of the relative frame of feed hopper is adjustable.
The two-end structure of cylinder is symmetrical;
The casing of blower fan is fixed on the bearing fan, and bearing fan is provided with and can makes the adjustable installation slotted eye of the relative frame activity of blower fan, and bearing fan fixes by bolt and frame.
Be provided with the forage skimming baffle that exceeds concave grate that millet straw is separated with grain between spiral case and the concave grate, the forage skimming baffle is fixed on the frame.
The utility model has the advantages that simple in structure, easy to operate, performance is feasible, long service life, cost is low.Threshing performance and production efficiency height can realize grass, grain, clever three separation, and separating property are good, and the clean rate height has alleviated hand labor intensity, safety, reliable.Normal condition only needs to operate about 2-3 people and gets final product, and this is convenient and practical to the general family in existing rural area.

The utility model embodiment is made to carry out the detailed description in a step below in conjunction with accompanying drawing:
The utility model mainly is made up of frame 7, cylinder 23, concave grate 19 and blower fan 13.
Be fixed with spiral case 2, feed hopper 12 and drum cover 8 on the frame 7, spiral case 2 is provided with grass outlet 3, and spiral case 2 covers in the left-hand end of cylinder 23; Feed hopper 12 is located at the forward right side of cylinder 23, and the lower port of its feed hopper 12 and concave grate 19 join; Drum cover 8 is located at the outer upside of cylinder 23, and can open easily, and the inboard of drum cover 8 is provided with and can makes by the shelling grass with the guide plate 9 of drum shaft to screw.Be provided with the forage skimming baffle 18 that millet straw is separated with grain between spiral case 2 and the concave grate 19, its forage skimming baffle 18 exceeds concave grate 19, also be the arc diameter of the arc diameter of forage skimming baffle 18 upper ends less than concave grate 19, will be when making millet straw in concave grate 19 arrival spiral cases 2 through a step, to stop that better grain enters spiral case 2, forage skimming baffle 18 is directly fixed on the frame 7.
Blower fan 13 is installed on the downside of frame 7.Blower fan 13 is horizontal blower fan, be provided with casing 15, blade 14 and power transmission shaft 16, blower fan 13 is fixed on the frame 7 by the bearing block 17 of both sides, the casing 15 of blower fan 13 is fixed on the bearing fan 17, bearing fan 17 is provided with and can makes the adjustable installation slotted eye of blower fan 13 relative frame 7 activities, and bearing fan 17 fixes by bolt and frame 7.The right axle head of blower fan 13 be provided with can with belt pulley 10 on the drum shaft 20 belt pulley 11 of transmission mutually.Power is by the external motor of cylinder, and drives blower fan by cylinder by belt pulley again.
For effectively stoping clean millet straw after the threshing into cylinder 23 that refluxes again, improve the clean careless grass output amount of thresher simultaneously, the housings in the spiral case 2 of the inner top side of grass outlet 3 are provided with and can stop the reflux careless baffle plate 22 that returns of cylinder 23 into of millet straw.
For millet straw is effectively isolated beyond the body, and be separated at a distance, do not mix mutually again simultaneously with grain and clever shell with body, the spiral case 2 of grass outlet 3 outsides be provided with can make millet straw become certain orientation go out to disembark body, curved shape go out careless deflector 4.
Feed hopper 12 and frame 7 link by bolt, and the height activity of feed hopper 12 relative frames 7 is adjustable.
Cereal is sent into by feed hopper 12, spike-tooth 5 extractings through cylinder 23 enter body, by the shelling thing in body through the repeatedly strike that is subjected to the cylinder spike-tooth 5 of high speed rotating between cylinder 23 and concave grate 19, the drum cover 8, curry, stir, and under the effect of guide plate 9, do the axial screw motion, finish threshing work simultaneously.Its grain and shell grain husk screen by concave grate 19, the grain husk shell blows out outside the frame 7 under the wind-force effect of blower fan 13, clean grain amasss in frame 7 inboards under the effect of deadweight, and millet straw under the effect of guide plate 9 beyond grass outlet 3 is discharged bodies, thereby realize millet straw, grain, three separation of clever shell.
