Abstract
The utility model discloses a threshing cylinder of a combine harvester for rice. The threshing cylinder comprises a cylinder body (1) and is characterized in that a truncated cone (2) is arranged on a charging end of the cylinder body (1); the cylinder body (1) is connected with the bottom of the truncated cone (2); and a spiral blade (4) is arranged on the surface of the truncated cone (2). The threshing cylinder is simple in structure, a problem of unsmooth feeding caused by blocking of a threshing device is resolved, frequency of breakdown maintenance is reduced, harvesting efficiency is improved by more than 10%, and labor intensity of operators is reduced.
Description
Technical field
The utility model relates to a kind of rice combine, specifically a kind of rice combine threshing cylinder.
Background technology
The harvested standing grain fringe of rice combine need be sent into sheller unit threshing through delivery chute, to adopting longitudinal axial flow mode threshing, is generally, by the threshing tooth on threshing cylinder, standing grain braid is entered to threshing cylinder threshing.In real work, because the axial direction of delivery chute and threshing cylinder is at a certain angle, therefore, usually to stop up, feeding is not smooth, needs to shut down artificial the eliminating, has a strong impact on the efficiency of harvesting.
Summary of the invention
The purpose of this utility model is to provide a kind of rice combine threshing cylinder that prevents putty.
The utility model is to adopt following technical scheme to realize its goal of the invention, a threshing cylinder, it comprises cylindrical shell 1, at the feed end of cylindrical shell 1, is provided with the frustum of a cone 2, cylindrical shell 1 was connected with the end of the frustum of a cone 2, and the surface of the frustum of a cone 2 is provided with helical blade 4.
The height of the frustum of a cone 2 described in the utility model is 10 ﹪～20 ﹪ of cylindrical shell 1 length, and the angle of two buses is 25 °～40 °.
For improving the abrasion resistance of helical blade 4, the outer rim welding-on of helical blade 4 described in the utility model has round bar 3, and the diameter of described round bar 3 is 8 ㎜～12 ㎜.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, and it is simple in structure; solved sheller unit because stopping up, and the not smooth problem of feeding has greatly reduced the number of times of shutting down troubleshooting; more than harvesting efficiency has improved 10 ﹪, also alleviated operator's labour intensity simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the expansion schematic diagram of the utility model helical blade.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As seen from Figure 1, Figure 2, a kind of rice combine threshing cylinder, it comprises cylindrical shell 1, at the feed end of cylindrical shell 1, is provided with the frustum of a cone 2, and cylindrical shell 1 was connected with the end of the frustum of a cone 2, and the surface of the frustum of a cone 2 is provided with helical blade 4.
The height of the frustum of a cone 2 described in the utility model is 10 ﹪～20 ﹪ of cylindrical shell 1 length, and the angle of two buses is 25 °～40 °.The length of the present embodiment threshing cylinder is 1800 ㎜, and the height of the frustum of a cone 2 is 240 ㎜.
During the utility model work, harvested standing grain fringe, through delivery chute, is sent into sheller unit threshing very smoothly by the helical blade 4 on the frustum of a cone 2.
For improving the abrasion resistance of helical blade 4, helical blade 4 adopts quality carbon steel, and shaping after-baking improves hardness, increases wearability.Meanwhile, the outer rim welding-on of helical blade 4 described in the utility model has round bar 3, and the diameter of described round bar 3 is 8 ㎜～12 ㎜.The diameter of the present embodiment circle bar 3 is 10 ㎜.
The utility model has solved sheller unit because stopping up, and the not smooth problem of feeding has greatly reduced the number of times of shutting down troubleshooting, more than harvesting efficiency has improved 10 ﹪, has also alleviated operator's labour intensity simultaneously.
