There have been proposals for handling cylinders having the

In the slack drum, since the harvested grain culms enter freely into the internal space of the slack drum main body formed by the front plate, the rear plate, and the plurality of support bars, the harvested grain culms do not reach the shaft of the slack drum and the support bars. It is easy to wind up, and the threshing efficiency may deteriorate.

In Patent Documents 1 to 5, a hollow pipe member is used as the support bar, and a mounting hole is passed through in the width direction orthogonal to the longitudinal direction of the hollow pipe member, and a handle is inserted into the mounting hole. It is disclosed that the treatment tooth is fixed to the hollow pipe member at two positions, radially inside and outside, in a state in which the treatment tooth is inserted and extended outward in a radial direction with respect to the scouring cylinder shaft. It is

In contrast to the handling cylinders described in Patent Documents 1 to 10, the following Patent Document 11 discloses a front plate and a rear plate fixed to the front and rear parts of the handling cylinder shaft, and along the circumferential direction of the handling cylinder shaft. a plurality of support bars supported by said front plate and said rear plate so as to be arranged in parallel with each other; A plate-shaped shielding plate that covers at least a part between adjacent support bars, and is positioned radially inward from the virtual outer surface that connects the outer peripheral surfaces of the adjacent support bars A handling cylinder with a plate is disclosed.

The threshing cylinder described in Patent Document 11 obtains a threshing action by a plurality of threshing teeth supported by the support bar, and the presence of the shielding plate effectively prevents the harvested grain culms from entering the internal space of the threshing cylinder body. Furthermore, by positioning the shielding plate radially inward from the imaginary outer surface, the processing space between the shielding plate and the inner surface of the treatment chamber can be expanded as much as possible. It is useful in that

However, the handling cylinder described in Patent Document 11 has room for improvement in terms of maintenance and/or replacement of the handling teeth.
During threshing, a large load is applied to the pliers, which may necessitate maintenance and/or replacement of the pliers.
In the threshing apparatus described in Patent Document 11, the front plate, the rear plate, and the support bar form a frame body (threshing cylinder main body), and the shielding plate is detachably attached to the frame body. Concatenated.
That is, in the structure described in Patent Document 11, the support bar itself forms the barrel main body, and removing the support bar is a very troublesome task.

It is also disclosed in the above-mentioned Patent Document 2 that the cut culms are prevented from entering the inside of the threshing cylinder main body by covering the space between the adjacent support bars with a shield plate. In the described arrangement, the shield plate is welded to the support bar, thus making maintenance and/or replacement of the support bar more cumbersome.
