Abstract

Disclosed is a multipurpose thresher, comprising a side outlet and a cap plate which are arranged on the rear side of the upper cap, the arced internal wall of the upper cap is provided with a left syncline gear roller, moving aprons are arranged on a feed inlet and a rear discharge port, and a cylinder is provided with 4 different teeth transverse gear racks. The back side of the two left-hand gear racks is welded with a right-hand tooth plate, the cylinder and an electrical motor are provided with stepped wheels, and the rotary speed can be adjusted. The utility model can thresh wheat, maize, beans, cereals, sorghum, rape, etc. The forage can be smashed in farm slack seasons, and in addition, separating blades are arranged on the rear end of the electrical motor shaft directly and the mixtures which are threshed can be separated cleanly through an arced air duct.

Description

Multipurpose thresher

The utility model belongs to multiduty thresher machine.

Existing all kinds thresher, as, wheat and husker sheller, its purposes is single, and the rate of comprehensive utilization of equipment is low, keeping, maintenance inconvenience, and threshing is pure inadequately, often is mixed with chaff, skin and so on impurity, also must separate in addition.In addition, though large-scale thresher threshing is pure, because its complex structure, purposes is still single and cost is high, so its a large amount of uses are restricted.

The purpose of this utility model provide a kind of of many uses, threshing is pure, compact conformation and the low thresher machine of cost.

Thresher provided by the utility model comprises: frame, cylinder, curved screen, loam cake, charging aperture, back discharging opening, motor, separation fan blade, material-collecting funnel etc.The garden of its cylinder also is symmetrically connected with 4 tooth bars on week, each 2 of left-hand and dextrad, and the back side of left-hand tooth bar is welded with the helical teeth plate that a plurality of dextrad of taking off corn ear are arranged.Be welded with the helical teeth roller that many left-hands are arranged on its loam cake arc inner wall, for quickening corn threshing and axially-movable, the trailing flank of loam cake is provided with the side outlet of a corncob, and the top of charging aperture is provided with an arc import baffle plate, and the top of back discharging opening is hinged with a backboard.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the status architecture cutaway view when taking off corn.

Fig. 4 is the A-A cutaway view among Fig. 3.

With reference to Fig. 2, motor (25) is hinged on the center, below of frame (15) by its support (23), and support steadily and compact integral structure; The axle front end of motor is equipped with secondary tower belt wheel (24), and links by V belt (21) and the secondary tower belt wheel (20) that is contained on cylinder (8) axle, makes the rotating speed of cylinder can the conversion by the threshing object difference.Adopt to separate fan blade (26) and directly be contained in cooling fan blade and the guard shield that replaces the original motor shaft rear end on the rear end of motor shaft, the wind-force of fan blade was directly blowed to by material-collecting funnel (22) flowed into grain chaff mixture in its below arc air duct (16), make mixture separation purer and simplified separating mechanism, also reached the purpose that reduces motor temperature.The arc air duct is hinged on the below of frame, also has mixture intake (28) on the air duct and puts out cereal mouthful (27).Four tooth bars (7,9) adopt the screw symmetry to be connected on the cylinder, and the tooth plate (29) at its two left-hands tooth bar back side respectively is 4～6.The left-hand helical teeth roller (6) that is welded on the loam cake inwall is 6～8.

With reference to Fig. 3, Fig. 4, when taking off corn, must make the dextrad helical teeth plate (29) at two tooth bars (7) back side be in the operating position, positive left-hand helical teeth must be in off-position.By forward and backward adjusting bolt (4,13), the gap between curved screen (14) and the cylinder is adjusted into: be 50～60mm in the gap that charging aperture (11) is located and back discharging opening (3) is located.The rotating speed of adjusting cylinder is a low speed.Unlatching is hinged on the side velar plate (17) of side mouth top, makes side outlet (19) be in opening; Backboard (1) is turned down sealing back discharging opening (3); Import baffle plate (10) pushed only seal 2/3 charging aperture (11).Behind electric motor starting, manually corn ear is sent in the cylinder by 1/3 charging aperture of chute feeder (12) and unlatching, corn ear is at two dextrad helical teeth, under the effect of two dextrad helical teeth plates and left-hand helical teeth roller (6), rotate vertically, through multiple impact and mutual extrusion, corn particle take off and with a spot of impurity through curved screen (14), material-collecting funnel (22), mixture intake (28) enters in the arc air duct (16), separate by the wind-force that separates fan blade (26), iblet is discharged by put out cereal mouthful (27), and impurity is discharged by arc air duct (16); Simultaneously corncob is discharged by side outlet (19) and the chute (18) that is riveted on the outlet below.

With reference to Fig. 1, when taking off wheat, must make the positive left-hand helical teeth of two tooth bars (7) be in the operating position, tooth plate (29) is in off-position.Gap between cylinder and the curved screen is adjusted into: at the 20～30mm of charging aperture place, at back exit 4～6mm.Drum rotation speed is at a high speed.Close side outlet, import baffle plate and be pushed into tops and fixing, make charging aperture be in full-gear; Make the back discharging opening be in opening by supporting (2) and backboard.Wheat is by the extruding of charging aperture through cylinder and curved screen, and straw is directly discharged by the back discharging opening, and it is separated that the wheat mixture enters air duct through screen cloth.

Grind that the grain, the chaff mixture that need separate or slack season during broken grass with artificial or machinery, use this machine need only closed side outlet and back discharging opening, open charging aperture, all the other are with to take off the wheat process identical.

The utility model can not only the threshing wheat, but but also threshing corn, beans, cereal, Chinese sorghum and rape etc., also can broken grass during slack season, a machine is multiplex, the utilization rate of equipment and installations height is safeguarded, keeping is convenient. Adopt separate blade directly to be contained in the motor shaft rear end, and can make grain, chaff separate pure by the arc air duct. In addition, this machine structure compactness, volume are little, easy to use, and cost is low.
