Abstract
The utility model discloses a grain unloading device of a grain combine harvester, which can prevent grain from blocking a horizontal unloading auger. The grain unloading device comprises a barn (1), wherein the horizontal unloading auger (4) and a vertical unloading auger (2) which is connected with the horizontal unloading auger (4) are arranged on the barn (1). The grain unloading device is characterized in that the screw pitch of the horizontal unloading auger (4) is smaller than that of the vertical unloading auger by 60%. The grain unloading device is simple in structure, easy to realize, convenient to use, and through trials, the horizontal unloading auger has no blocking phenomenon.
Description
Technical field
The utility model relates to a kind of grain combine, specifically a kind of grain combine discharge mechanism.
Background technology
The silo of grain combine generally is provided with mechanical discharge mechanism, and it comprises horizontal unloading screw conveyor, the vertical unloading screw conveyor be connected with horizontal unloading screw conveyor.For making the horizontal unloading screw conveyor of the orderly inflow of cereal in silo, prevent that horizontal unloading screw conveyor from blocking, usually above horizontal unloading screw conveyor, be provided with umbrella shape screw feeder cover plate, and, in order to adapt to the unloading needs of various different cereal, also be provided with adjustable plate on umbrella shape screw feeder cover plate, to regulate the interval between umbrella shape screw feeder cover plate and silo bulkhead, also umbrella shape screw feeder cover plate being designed to of even having is swingable, in the hope of cereal flow preferably, prevents that horizontal unloading screw conveyor from blocking, its complex structure, used inconvenience.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly prevents that cereal from blocking the grain combine discharge mechanism of horizontal unloading screw conveyor.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of grain combine discharge mechanism, it comprises silo, the vertical unloading screw conveyor that silo is provided with horizontal unloading screw conveyor, is connected with horizontal unloading screw conveyor, the pitch of horizontal unloading screw conveyor is less than the pitch of vertical unloading screw conveyor, and the pitch of horizontal unloading screw conveyor is less than 60 ﹪ with the ratio of the pitch of vertical unloading screw conveyor.
Preferred version of the present utility model is that the pitch of horizontal unloading screw conveyor equals 40 ﹪～50 ﹪ with the ratio of the pitch of vertical unloading screw conveyor.
The top of the horizontal unloading screw conveyor of the utility model is provided with umbrella shape screw feeder cover plate.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, and it is simple in structure, realizes easily, easy to use, and through on probation, horizontal unloading screw conveyor not there will be clogging.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to partial view.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As seen from Figure 1, Figure 2, a kind of grain combine discharge mechanism, it comprises silo 1, the vertical unloading screw conveyor 2 that silo 1 is provided with horizontal unloading screw conveyor 4, is connected with horizontal unloading screw conveyor 4, the driving shaft of horizontal unloading screw conveyor 4 is connected by bevel gear 5 with the driving shaft of vertical unloading screw conveyor 2, the pitch of horizontal unloading screw conveyor 4 is less than the pitch of vertical unloading screw conveyor 2, and the pitch of horizontal unloading screw conveyor 4 is less than 60 ﹪ with the ratio of the pitch of vertical unloading screw conveyor 2.
Preferred version of the present utility model is that the pitch of horizontal unloading screw conveyor 4 equals 40 ﹪～50 ﹪ with the ratio of the pitch of vertical unloading screw conveyor 2.
The top of the horizontal unloading screw conveyor 4 of the utility model is provided with umbrella shape screw feeder cover plate 3.
The capacity of the present embodiment silo 1 is 980 ㎏, and the pitch of horizontal unloading screw conveyor 4 is 63, and vertically the pitch of unloading screw conveyor 2 is 140, and ratio between two is 45 ﹪.
During the utility model work, the grain threshing that separating mechanism transports harvesting, then by the screw feeder of delivering grain, send into silo 1 after by dressing mechanism, being cleaned.When the cereal of harvesting arrives silo 1 capacity or needs unloading, controlling organization level of control unloading screw conveyor 4 and vertically unloading screw conveyor 2 work, due to, the pitch of horizontal unloading screw conveyor 4 is 45 ﹪ with the ratio of the pitch of vertical unloading screw conveyor 2, cereal in silo 1 can draw off silo 1 smoothly, obstruction that can occurred level unloading screw conveyor 4.
Claims (3)
1. grain combine discharge mechanism, it comprises silo (1), the vertical unloading screw conveyor (2) that silo (1) is provided with horizontal unloading screw conveyor (4), is connected with horizontal unloading screw conveyor (4), it is characterized in that the pitch of horizontal unloading screw conveyor (4) is less than the pitch of vertical unloading screw conveyor (2), the pitch of horizontal unloading screw conveyor (4) is less than 60 ﹪ with the ratio of the pitch of vertical unloading screw conveyor (2).
2. grain combine discharge mechanism according to claim 1, is characterized in that the pitch of horizontal unloading screw conveyor (4) and the ratio of the pitch of vertical unloading screw conveyor (2) equal 40 ﹪～50 ﹪.
3. grain combine discharge mechanism according to claim 1 and 2, is characterized in that the top of horizontal unloading screw conveyor (4) is provided with umbrella shape screw feeder cover plate (3).
