Description

The present invention relates to a handling cylinder that threshes a harvested culm supplied to a handling room.

As a handling cylinder for performing grain removal processing on the harvested grain stile supplied to the handling chamber, the front plate and the 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 the front plate and the rear plate so as to be arranged, and a plurality of handle teeth provided so as to extend outward in the radial direction to each of the plurality of support bars. A handling cylinder having a handle has been proposed (see, for example, Patent Documents 1 to 10 below).

In the handling cylinder, the cutting grain culm freely enters the internal space of the handling cylinder main body formed by the front side plate, the rear side plate, and the plurality of support bars, so that the cutting grain culm is placed on the handling cylinder shaft and the support bar. It is easy to wrap and the efficiency of grain removal may deteriorate.

In Patent Documents 1 to 5, a hollow pipe member is used as the support bar, and the mounting hole is penetrated in the width direction orthogonal to the longitudinal direction of the hollow pipe member, and a tooth is provided in the mounting hole. It is disclosed that the teeth are fixed to the hollow pipe member at two locations, inside and outside in the radial direction, in a state where the teeth are inserted and extended outward in the radial direction with respect to the barrel axis. Has been done.

In contrast to the handling cylinders described in Patent Documents 1 to 10, the following Patent Document 11 describes the front plate and the rear plate fixed to the front and rear portions of the handling cylinder shaft, along the circumferential direction of the handling cylinder shaft. A plurality of support bars supported by the front plate and the rear plate so as to be arranged, and a plurality of teeth provided so as to extend outward in the radial direction to each of the plurality of support bars. A plate-shaped shielding plate that covers at least a part between adjacent support bars, and is located radially inward from the virtual outer surface that connects the outer peripheral surfaces of the adjacent support bars. A handling barrel with a plate is disclosed.

The handling cylinder described in Patent Document 11 effectively allows the cut grain culm to enter the internal space of the handling cylinder main body due to the presence of the shielding plate while obtaining the threshing action by the plurality of handling teeth supported by the support bar. Further, by locating the shielding plate radially inward from the virtual outer surface, the processing space between the shielding plate and the inner surface of the handling chamber can be expanded as much as possible. It is useful in that it is.

However, the handling cylinder described in Patent Document 11 has room for improvement in terms of maintenance and / or replacement of the handling teeth.
Since a large load is applied to the teeth during the threshing process, it may be necessary to perform maintenance and / or replacement of the teeth.
In the threshing device described in Patent Document 11, the front plate, the rear plate, and the support bar form a frame body (handler body), and the shielding plate is detachably attached to and detachable from the frame body. It is connected.
That is, in the configuration described in Patent Document 11, the support bar itself forms the handling cylinder body, and removing the support bar is a very troublesome task.

It should be noted that it is disclosed in the above-mentioned Patent Document 2 that the invasion of the cut grain culm into the inside of the handling cylinder body by covering the space between the adjacent support bars with a shielding plate, but this Patent Document 2 also discloses. In the configuration described, the shielding plate is welded and fixed to the support bar, thus making maintenance and / or replacement work of the support bar more cumbersome.
