り、脱穀性能が低下したりする不具合がある。Therefore, when assembling the handling cylinder to the threshing part, it is necessary to bolt it in a narrow gap between the front and rear walls of the handling chamber and the front and rear end face plates of the handling cylinder. Is hard to do, and moreover, there is a gap between the peripheral wall of the threshing section and the handling cylinder,
It was necessary to mount the handle while adjusting the relative positions of the handle teeth of the handle and the accessory members such as cutting blades fixed to the peripheral wall of the threshing part, and this work required a lot of trouble. If the gap or the related position is incorrect, there is a problem that interference between the handling tooth and the cutting edge occurs or threshing performance deteriorates.

When supporting the handling cylinder in which is fitted between the front and rear walls forming the handling chamber, one of the front and rear dustproof wheels is fixed and the other is removable, and the handling cylinder support shaft is arranged in the axial direction of the handling cylinder. The insertion hole is opened, and the handling cylinder support shaft is shaped so that the relative position does not change so as to transmit the drive in the rotation direction with respect to the insertion hole, and it is inserted freely in the axial direction,
Provided between the front and rear walls of the front and rear walls that pivotally support the handling cylinder support shaft is a front and rear positioning collar that is externally fitted to the handling cylinder support shaft, and fix one of the positioning collars to the same side shaft support and handle the other. An object is to provide a handle barrel structure of a combine, which is slidable / fixable with respect to a barrel support shaft.

摺動するので、作業が更に容易になる。When the handling cylinder is mounted in the handling chamber, the front positioning collar is attached at a predetermined position and the rear positioning collar is fitted in the rear shaft support so that the inner end surface of the collar is flush with the inner surface of the rear wall of the handling chamber. The handling cylinder with the rear dustproof wheel fitted in the recess on the rear end face is inserted into the handling chamber, and the handling barrel support shaft is inserted into the pipe-shaped member of the handling barrel from the front through the front positioning collar. To the specified position in the front, slide the rear positioning collar in the forward direction to prevent the handle barrel support shaft from being pulled out of the handle room, and fix the rear dustproof wheel to the rear wall to secure the handle barrel to the handle room. Can be easily attached to the predetermined position. Further, a pipe-shaped member is disposed on the axis of the handling cylinder, the pipe-shaped member is located in front and rear end face recesses formed on the front and rear end faces of the handling barrel, and the front and rear end faces of the pipe-shaped member are front and rear end faces. When the handle is removed, the handle is pushed backward by the rear end of the pipe-shaped member when the handle is removed, so that it is flush with the rear wall of the handle. Since the collar slides, the work becomes easier.

る。According to the present invention, the inner end portions of the front and rear dustproof wheels mounted on the front and rear walls of the handling chamber are fitted in the front and rear concave portions formed on the front and rear end surfaces so as to be rotatable about the shaft center. When supporting the handling barrel between the front and rear walls that form the handling chamber, one of the front and rear dustproof wheels is fixed and the other is removable, and the handling barrel support shaft is inserted in the axial direction of the handling barrel. A hole is opened, and the handling cylinder support shaft is shaped so that the relative position does not change with respect to the insertion hole so as to transmit the drive in the rotation direction, and it is inserted in the axial direction so that it can be removed freely, and the handling cylinder support shaft is supported. A front and rear positioning collar externally fitted to the handling cylinder support shaft is provided between the shaft support portions of the front and rear walls, one of the positioning collars is fixed to the shaft support portion on the same side, and the other is slid against the handling cylinder support shaft. Since it can be moved and fixed freely, it is easy to attach and detach the handling cylinder. Work can be finished in a short period of time.

という効果がある。That is, the difficult work such as bolting in the narrow gap between the front and rear walls of the handling chamber and the front and rear end face plates of the handling barrel, which is necessary in the conventional structure, is eliminated, and in the present invention, the threshing portion is eliminated. The gap between the peripheral wall and the drum, the cutting teeth fixed on the tooth of the drum and the peripheral wall of the threshing part, and the relative positions of the front and rear end face plates of the drum and auxiliary members such as front and rear dustproof wheels are automatically positioned. As a result, these adjustments are not required and the work is facilitated. Furthermore, the clearances and the relative positions between the respective parts of the handling cylinder, the respective parts of the handling chamber, and the attached members are accurate, so that the threshing performance is improved.

済むようにすることができる。Further, a pipe-shaped member is disposed on the axis of the handling cylinder, the pipe-shaped member is located in the front and rear end face recesses formed on the front and rear end faces of the handling barrel, and the front and rear end faces of the pipe-shaped member are handled. By making the front and rear end faces flush with each other, it is possible to move the positioning collar outward until it is flush with the wall of the handling chamber by sliding the handling barrel in the axial direction when removing the handling barrel. As a result, a special tool such as a puller is not required, the labor for removing the handling cylinder is saved, and the work can be performed easily and in a short time.
