Embodiment
For making object of the invention process, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is further described in more detail.Described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.Below in conjunction with accompanying drawing, embodiments of the invention are described in detail:
In describing the invention, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore limiting the scope of the invention can not be interpreted as.
Fig. 1 illustrates the structural representation of the drum cover that embodiments of the invention provide.This drum cover comprises drum cover body 3 and is installed on front panel 1 and the rear board 2 at drum cover body 3 two ends.The cross section of drum cover body 3 is circular arc, and it makes simple, and quality is light, good manufacturability, and wall is smooth cambered surface, and stalk flows smooth and easy in threshing chamber.The inner periphery of drum cover body 3 sets gradually the first grass guide board group 4, second grass guide board group 5 and the 3rd grass guide board group 6 along its axial (as direction of arrow in Fig. 1) from front to back.First grass guide board group 4 comprises the non-dismountable grass guide board of the first grass guide board group.Second grass guide board group comprises the non-dismountable grass guide board 51 of the second grass guide board group, the large non-dismountable grass guide board 52 of radius and detachable grass guide board 53.3rd grass guide board group 6 also comprises the non-dismountable grass guide board 61 of the 3rd grass guide board group, the large non-dismountable grass guide board 62 of radius and detachable grass guide board 63.The non-dismountable grass guide board 51 of the second grass guide board group, the large non-dismountable grass guide board 52 of radius and detachable grass guide board 53, are corresponding identical structures with the non-dismountable grass guide board 61 of the 3rd grass guide board group, the large non-dismountable grass guide board of radius 62 with detachable grass guide board 63, but it arrange angle difference inside drum cover body 3.First grass guide board group 4 is 50 °-60 ° with the central axis angle a of drum cover body 3, preferably 55 °.Second grass guide board group 5 is 55 °-65 ° with the central axis angle b of drum cover body 3, preferably 60 °.3rd grass guide board group 6 is 60 °-70 ° with the central axis angle c of drum cover body 3, preferably 64 °.The grass guide board setting of 3 kinds of angles achieves cereal first grass guide board group 4 when initial feeding makes stalk enter fast, second grass guide board group 5 is positioned at middle threshing part, be convenient to threshing operations, after stalk is broken, under the 3rd grass guide board group 6 is auxiliary, slowly comb plays discharge, add the grain threshing time, effectively increase threshing performance and decrease threshing percent of loss.
First grass guide board group 4 comprises the non-dismountable grass guide board of the first grass guide board group, and it is welded in the inner side of drum cover body 3.The internal diameter of the detachable grass guide board 53 of the second grass guide board group is identical with the internal diameter of non-dismountable grass guide board 51.The internal diameter of the non-dismountable grass guide board of large radius 52 of the second grass guide board group is greater than the internal diameter of non-dismountable grass guide board 51, and namely the effective width d of the non-dismountable grass guide board of large radius 52 is less than detachable grass guide board 53 effective width e, preferably e=2d.After being pulled down by detachable grass guide board 53, threshing cylinder ratch is effectively increased to the height of grass guide board, when feed quantity strengthens, can effectively ensure that stalk passes through smoothly, when particularly gathering in blue or green wet crop, effectively can reduce entrainment loss.
The detachable grass guide board 53 of the second grass guide board group is overlapping with the non-dismountable grass guide board of large radius 52 to be installed.Particularly, the non-dismountable grass guide board 51 of the second grass guide board group and the non-dismountable grass guide board 52 of large radius are welded in the inner side of drum cover body 3.The two ends of the detachable grass guide board 53 of the second grass guide board group arrange installing plate 531, and detachable grass guide board 53 is connected to the inner side of drum cover body 3 by installing plate 531 matching fastener.The detachable grass guide board 53 of the second grass guide board group also can arrange installing hole 532, the non-dismountable grass guide board 52 of large radius arranges the hole with installing hole 532 corresponding matching, and with securing member, detachable grass guide board 53 and non-dismountable grass guide board 52 overlap of large radius are installed, its mounting structure is firm, easy accessibility, is convenient to change and safeguards.。The non-dismountable grass guide board 61 of the 3rd grass guide board group, the large non-dismountable grass guide board of radius 62 are identical with detachable grass guide board 53 with the non-dismountable grass guide board 51 of the second grass guide board group, the greatly non-dismountable grass guide board of radius 52 with the structure of detachable grass guide board 63, therefore omission describes.
Above embodiment, only in order to technical scheme of the present invention to be described, is not used for limiting practical range of the present invention.In every case the equivalence change done in protection scope of the present invention and modification, all should think and fall in protection scope of the present invention.
