Of the present utility model clean tube by inner several stacks, be the circular hollow solid leak of peviform, the lampshade shape top cover on leak top is formed.
Air-introduced machine of the present utility model by with drum shaft by the bel-drivenn rotating shaft, with the rotating shaft spaced fan blade that is fixed with one, the air-introduced machine upper end is formed with air-flow plate and the wheat husk outlet that install junction, blower fan bend pipe end.
Adjustment of the present utility model separates the device of notch board lifting by separating the screw that the axial symmetry of notch board circumferential location is equipped with, what be connected with screw thread separates the notch board setscrew nut, with separate notch board setscrew nut one and pass the screw rod of leaving through hole on the frame, the nut of the spiral positioning that respectively be equipped with at the upper and lower screw rod position of frame through hole is formed.
The fan-shaped cornerite of separation notch board of the present utility model can be 100 degree.
Straw separator of the present utility model is by sieving sheet, being fixed in the conulite that guiding grain conveying device inlet is played in sieve sheet bottom, with the side upper end grass outlet composition of straw separator one.
The shape of blower fan bend pipe of the present utility model can be " ∩ " shape.
Grain conveying device of the present utility model is made up of the screw feeder of carrying by certain orientation in cylinder, the cylinder.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the front view that small-sized air-flow cleans thresher.
Fig. 2 is the left view that small-sized air-flow cleans thresher.
Fig. 3 is the structural representation of fan-shaped separation notch board.
The utility model is described in further detail below in conjunction with embodiment:
As shown in the figure; small-sized air-flow cleans thresher to have: feeder 1; cut streaming rasp bar threshing cylinder 2; the fan-shaped cornerite in threshing cylinder 2 lower ends is the separation notch board 3 of 100 degree; be positioned at and separate notch board 3 bottoms by sieve sheet 4; be fixed in sieve sheet 4 bottoms and play the conulite 5 of guiding grain conveying device 10 inlets; the straw separator of forming with the side of straw separator 7 one upper end grass outlet 67; the bottom of straw separator 7 is connected to by cylinder 8; press the grain conveying device 10 of screw feeder 9 compositions of certain orientation conveying in the cylinder 8; grain conveying device 10 be connected by with drum shaft 11 screw feeder conveying axis 13 by belt 12 transmissions; with the rotating shaft 13 of screw feeder conveying axis end one ', the spinner of forming with spaced blade 14 of rotating shaft 13 ' be fixed with one and shell 15 16.Spinner 16 upper ends connect by inner several stacks by pipeline 17, are the circular hollow solid leak 18 of peviform, and the lampshade shape top cover 19 on leak 18 tops is formed cleans tube 20.By with drum shaft 11 rotating shaft 22 by belt 21 transmissions, with the rotating shaft 22 spaced fan blade 23 that is fixed with one, the air-introduced machines 26 that air-flow plate 24 that install air-introduced machine 26 upper ends and junction, blower fan bend pipe 27 end and wheat husk outlet 25 are formed are positioned at frame 31 lower ends.Clean between tube 20 and the air-introduced machine 26 and be connected by the blower fan bend pipe 27 that is shaped as " ∩ " shape, separate notch board 3 about the end bottom be symmetrically installed with the device 28 of adjustment separation notch board lifting.The device of adjusting the lifting of separation notch board is by separating the screw 29 that the axial symmetry of notch board 3 circumferential location is equipped with, separate notch board setscrew nut 30 with screw 29 is threaded, with separate notch board setscrew nut 30 one and pass the screw rod 32 of leaving through hole on the frame 31, the nut of the spiral positioning that respectively be equipped with at upper and lower screw rod 32 positions of frame 31 through holes 33 is formed.
During use, after cereal is fed by feeder 1, threshing cylinder 2 is with grain threshing, because it is less to separate the cornerite (100 degree) of notch board 3, best clearance can make the screw rod 32 upper and lower displacements that are threaded with it, thereby make and the also upper and lower thereupon displacement of the setscrew nut 30 of screw rod 32 one by the rotation adjustment of nut 33 again, by being threaded in the effect that separates the axial screw rod 29 of notch board 3 circumferential location, separating notch board 3 and promptly be adjusted.Cylinder 2 with separate the screening effect of grain after notch board 3 is rubbed, impurity through sieve sheet 4, fall into conulite 5 and enter grain conveying device 10 inlets, the screw feeders 9 in the grain conveying device 10 are transported to grain, impurity in the spinner 16 continuously.Under its blade that is rotating 14 effects, spinner 16 17 is transported to scourclean 20 by the road with cereal and impurity, under the acting in conjunction of the circular hollow solid leak 18 of five stacks in cleaning tube 20 and the lampshade shape top cover 9 on leak top, wheat falls into the grain outlet.Impurityes such as wheat husk enter in the air-introduced machine 26 through " ∩ " shape blower fan bend pipe 27, discharge wheat husk outlet 25 with fan blade 23.Cereal and impurity entered grain conveying device 10 inlets with conulite 5 when, things such as straw were by discharging with the side upper end grass outlet 6 of straw separator 7 one.
The technical parameter of most preferred embodiment:
Threshing cylinder 2 is circular by width of cloth dish, and diameter is 400 millimeters, long 340 millimeters of cylinder, and the rasp bar that six roots of sensation D type is housed is formed.Rotating speed is 1300 rev/mins, feed quantity 1 Kilograms Per Second.
