Description
Technical field
The present invention relates to the detachment roller of combine, particularly the connected mode of a kind of drive shaft structure of threshing cylinder of combine and the width dish with supporting threshing toothed bar, belongs to field of agricultural machinery.
Background technology
The drive shaft structure of the threshing cylinder of conventional track self-propelled combine often adopts filled circles steel construction, along with the continuous increase of taken off material variety and feed quantity, to impact and the load also corresponding increase of cylinder, if still adopt said structure, easily cause poor rigidity, Heavy Weight.So recently engender and adopt steel pipe to embed the welded structure of spindle nose, but be connected unreasonable due to embedded mode and the width dish that supports threshing toothed bar, the deficiency of threshing cylinder distortion, sealing-off, installation inconvenience still exists.
Summary of the invention
The object of this invention is to provide a kind of threshing cylinder of combine, there is the distinguishing features such as rigidity is high, lightweight, indeformable, driving torque large, it is reliable to connect, mounting or dismounting are convenient.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of threshing cylinder of combine, it is characterized in that: the drive shaft of threshing cylinder comprises driving spindle nose, stage casing steel pipe, supporting spindle nose, roundel, the stage casing of drive shaft adopts steel pipe, two ends embed round steel spindle nose respectively, and stage casing steel pipe is pressed the multiple roundel of predetermined distance melting welding, described round steel spindle nose is provided with axial keyway, it is the uniform multiple installing holes in the center of circle that described roundel is provided with axis of rotation, the connection of the flange and front and back width dish that are arranged on the drive shaft two ends of threshing cylinder adopts flat key to connect, roundel in the middle of the drive shaft being welding in threshing cylinder and the connection of middle part width dish with bolts.
Preferably, the degree of depth of round steel spindle nose embedding steel pipe is greater than 1/3 of its steel tube inner hole diameter.
Preferably, the multiple roundel diameters be welding on the steel pipe of stage casing are arranged as by crop approach axis and diminish gradually, namely first maximum, last is minimum, and the outer edge radius of a rear roundel is less than the distance at center of the installing hole distance drive shaft of previous roundel.
Preferably, the effective length of flat key is 0.8 ~ 1.5 times that drives spindle nose input diameter.
In sum, the present invention has following beneficial effect:
1, structure of the present invention is simple, easy to implement, is conducive to I&M.
2, when feed quantity increase suddenly, cylinder blocking time also can not deform, the catastrophe failure such as sealing-off.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1-2, drive shaft 324 structure of the threshing cylinder 32 of combine, comprising: drive spindle nose 324a, stage casing steel pipe 324b, supporting spindle nose 324c and roundel 324d.
The drive shaft 324 of the threshing cylinder 32 of described combine adopts and embeds driving spindle nose 324a in the front end of stage casing steel pipe 324b, and rear end embeds supporting spindle nose 324c, and stage casing steel pipe 324b presses the welded structure of the multiple roundel 324d of predetermined distance melting welding.
As preferably of the present invention, the degree of depth that driving spindle nose 324a and the supporting spindle nose 324c of the drive shaft 324 of the threshing cylinder 32 of described combine embed stage casing steel pipe 324b is respectively greater than 1/3 of its steel tube inner hole diameter.
The adpting flange 324e of drive shaft 324 rear and front end and the connection of width dish 321 of the threshing cylinder 32 of described combine adopt flat key to connect.
As preferably of the present invention, flat key length is 0.8 ~ 1.5 times that drives spindle nose 324a input diameter.
The stage casing steel pipe 324b of the drive shaft 32 of the sheller unit 1 of described combine presses the multiple roundel 324d of setpoint distance melting welding, it is the uniform multiple installing holes in the center of circle that roundel 324d is provided with axis of rotation.
As preferably of the present invention, the diameter being welding in the roundel 324d on the steel pipe 324b of stage casing is arranged as by crop approach axis: diminish gradually, namely first maximum, last is minimum.In addition, the rear outer rim of a roundel 324da and the distance of pivot than the installing hole of previous roundel 324db and the distance of pivot little.
As preferably of the present invention, melting welding adopts bolt 322 to connect in the roundel 324d in threshing cylinder 1 drive shaft 32 stage casing and the connection of width dish 321.
The present invention has following beneficial effect: structure of the present invention is simple, easy to implement, is conducive to I&M, thus when impulsive force or feed quantity increase suddenly, the catastrophe failure such as cylinder also can not deform when blocking, sealing-off.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification, as long as but be all subject to the protection of Patent Law in right of the present invention.
