Abstract
The utility model provides a centrifugal winnowing machine which belongs to an agricultural machine; a main shaft (3) is arranged on a machine frame (6) through a bearing, the main shaft is provided with a belt pulley (5), a blade (10) is arranged on a rotor impeller (8) in a machine casing (2), and the machine casing is also provided with a feed port (1) and a discharge port (7); the utility model can thresh at the second time, the winnowing grain piles concentrates, the separating effect of the grains and grain casings is good, and 95 percent of the cleaning percentage is achieved.
Description
The utility model provides a kind of winnowing machine, belongs to a kind of farm implements, is used for separating of grain grain and husk after the threshing.
Used winnowing machine is a belt-conveying type at present.Cereal-granules after the threshing is placed on the belt, and the transmission by belt throws away cereal.This winnowing machine, the belt wearing and tearing that exist cereal-granules to cause, belt is fragile, particle and husk inferior separating effect, the particle of the band husk that does not purify can not carry out the secondary threshing, and the grain heap after raising out is not concentrated.
The purpose of this utility model provides a kind of centrifugal winnowing machine, to improve the separating effect of cereal-granules and husk.
The utility model is achieved in that main shaft is installed on the casing by bearing body, and belt pulley is installed on the main shaft, on the impeller of rotor in the casing blade is installed, and also has charging aperture and discharging opening on the casing.
Adopt the centrifugal winnowing machine of said structure, during use, main shaft drives the impeller of rotor rotation.Cereal-granules after the threshing is dropped into charging aperture, and rotating blades is raised out cereal-granules, husk along discharging opening.Different with the proportion of husk because of particle, heavier cereal-granules is raised far, and lighter husk is raised closely, thereby reaches the separation purpose.Simultaneously, the particle of the band husk that does not purify rotates by the high speed of impeller of rotor and blade, and husk is separated, and has realized the secondary threshing.During the grain that this winnowing machine is raised out is heaped, husk and cereal-granules separator well, winnow-cleaning rate can reach 95%.
Below in conjunction with description of drawings structure of the present utility model.
Fig. 1 is the schematic diagram of the utility model structure.Fig. 2 is its A-A profile.Fig. 3 is the schematic diagram of blade shape.
As shown in drawings, on the centrifugal winnowing machine of the utility model, main shaft (3) is installed on the frame (6) by bearing body (4), belt pulley (5) is installed on the main shaft, on the impeller of rotor (8) in the casing (2) blade (10) is installed, one side of casing has charging aperture (1), also has discharging opening (7) on casing.
Impeller of rotor (8) is installed on the main shaft (3) by nut (9).
As shown in Figure 3, the shape of blade (10) can be straight plate shape.
Belt pulley (5) also can be given the device of main shaft transmission of power for other.
Claims (1)
- Centrifugal winnowing machine, it is characterized in that, on described winnowing machine, main shaft (3) is installed on the frame (6) by bearing body (4), belt pulley (5) is installed on the main shaft, on the impeller of rotor (8) in the casing (2) blade (10) is installed, a side of casing has charging aperture (1), also has discharging opening (7) on casing.
