Specific embodiments

Shown in Fig. 1 (a), Fig. 1 (b), the compound cylindrical grain cleaner of the utility model, the shell body of cylindrical grain cleaner and cycle winnowing device is solidly fixed, and both communicate by inner chamber, and cycle winnowing device is positioned at the technology end of cylindrical grain cleaner, above clean grain outlet.By sieve 4 in the cylindrical grain cleaner part and outer sieve 5, cycle winnowing device 2, power set 15 critical pieces are formed.

In sieve 4, sieve 5 outward and be contained in respectively on the screen drum 6, screen drum 6 front ends are holding in the palm with support roller 9 and are being fixed on the frame 16, the rear end is fixed on the frame 16 by power set 15, the peripheral usefulness of whole sieve nest top cover 3 is topped.

Frame 16 belows are located at two little

assorted outlets

12,14, and the right is provided with big assorted outlet 10 and staircase 8, and there is hopper 7 front upper place, and there are road wheel and universal wheel 1 in the frame below, and the rear is furnished with cycle winnowing device 2.

Cycle winnowing device 2 as shown in Figure 2, by impurities removal auger 21, dividing plate 22, observe AD 23, blinds device 24, blower fan 25, volume damper 26, hagioscope 27, air channel 28, Grain evening device 29, feeding roller 210, clean grain exports 211 compositions such as grade.

Cycle winnowing device 2 vertically is provided with, and its inner chamber upper end level is provided with cylindric blinds device 24, one ends and blower fan 25 is connected, and blinds device 24 upper and lowers have arc, and upper and lower arc both side edges is fixed on housing 30 inwalls; The radius of circle of last arc is greater than the radius of circle of arc lower plate, and two arc intersections are gapped; Arc lower plate below is connected with vertically disposed dividing plate 22, and dividing plate 22 both sides are fixed on housing 30 inwalls, and inner chamber is divided into the impurity removal passage of left and right-hand air channel 28 with dividing plate 22; The vertically extending volume damper 26 of air channel 28 above arc right-hand members is divided into into and out of the air channel 281,282, and volume damper 26 both sides and housing 30 inwalls are dynamically connected, and, and communicates above clean grain outlet 211 into and out of air channel 281,282; Exhaust passage 282 sidewalls are provided with hagioscope 27, are provided with baffle plate in the air inlet duct 281; Impurity removal passage lower end sidewall has impurity-discharging stranding cage 21.
