Description

Barrel

The present invention relates to a handling cylinder in a threshing apparatus.

As a handling cylinder for performing threshing processing on the harvested cereal meal supplied to the handling room, along the front plate and the rear plate fixed to the front and rear parts 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 handling teeth provided so as to extend radially outward of each of the plurality of support bars. A handling cylinder has been proposed (see, for example, Patent Documents 1 to 10 below).

In the handling cylinder, the harvested cereal rice cake freely enters the internal space of the handling cylinder main body formed by the front plate, the rear plate, and the plurality of support bars, so that the harvested rice cake cereal is attached to the handling cylinder shaft and the support bar. It is easy to wind up and 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 penetrated in a width direction perpendicular to the longitudinal direction of the hollow pipe member, and teeth are handled in the mounting hole. It is disclosed that the tooth-handling is fixed to the hollow pipe member at two locations on the inner side and the outer side in the radial direction in a state where the tooth-handling is extended outwardly with respect to the radial direction with respect to the shaft of the barrel. Has been.

In contrast to the handling cylinders described in Patent Documents 1 to 10, the following Patent Document 11 describes a front plate and a rear plate fixed to the front and rear parts of the handling cylinder shaft, and a circumferential direction of the handling cylinder shaft. A plurality of support bars supported by the front plate and the rear plate, and a plurality of teeth handling teeth provided to extend radially outward of each of the plurality of support bars; A shield plate that covers at least a part between adjacent support bars, and is shielded radially inward from a virtual outer surface that connects the outer peripheral surfaces of adjacent support bars. A cylinder with a plate is disclosed.

The handling cylinder described in Patent Document 11 is effective in that the harvested culm enters 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 tooth handling supported by the support bar. Furthermore, by positioning 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. In that respect, it is useful.

By the way, since a large load is applied to the tooth handling during the threshing process, it may be necessary to perform maintenance and / or replacement of the tooth handling.
In this regard, in the threshing apparatus described in Patent Document 11, the support bar itself forms a barrel body, and it is very troublesome to remove the support bar.

It is disclosed in Patent Document 2 that preventing the harvested cereal from entering the inside of the barrel body by covering the adjacent support bars with a shielding plate. In the described arrangement, the shielding plate is welded to the support bar, so that maintenance and / or replacement of the support bar is more troublesome.

On the other hand, Patent Document 12 below includes a handling cylinder body formed by a front side plate, an intermediate side plate, and a rear side plate fixed to a handling cylinder shaft, and a cylindrical body fixed in a state surrounding them. A handle in which a plurality of plates on which teeth are erected are detachably attached to the barrel body with fastening members such as bolts in a state where the plates are arranged on the outer circumferential surface of the barrel body with a circumferential interval. A torso is disclosed.

The handling cylinder described in Patent Document 12 is effective in that only a desired plate can be removed without removing the handling cylinder body, but is improved in terms of durability and support stability of the plate. There is room for.

That is, when performing a hitting process on the cereal with the tooth treatment, the tooth treatment is perpendicular to the tangential direction of the virtual circle that is the rotation locus of the tooth treatment, that is, the longitudinal direction of the tooth treatment. Impact force is applied in the direction.

Here, in the handling cylinder described in Patent Document 12, the plate is disposed so that the plate surface is substantially orthogonal to the longitudinal direction of the tooth-handling, and by a fastening member along the longitudinal direction of the tooth-handling. Fastened to the outer surface of the barrel body.
In such a configuration, the impact force acting on the tooth handling during the impact treatment by the tooth handling acts as a force in the direction of shearing the fastening member, and as a result, durability and support of the plate Stability may be impaired.

Further, in Patent Documents 1, 3 to 4, 8, 10 to 11 and 13, regarding the arrangement of the plurality of tooth handling teeth, the position of the tooth handling front and rear direction is shifted between the tooth handling frames adjacent in the circumferential direction. Is disclosed.
Particularly, in Patent Documents 1 and 11, the threshing process for the harvested culm can be efficiently performed by shifting the arrangement pitch of the tooth handling by ½ between the tooth handling frames adjacent in the circumferential direction. Is described.

By the way, from the viewpoint of threshing efficiency, it is preferable to change the setting position of the tooth handling depending on the type, amount, and / or moisture content of the harvested cereal but the tooth handling in any of the above-mentioned patent documents. The installation position of was fixed and could not be changed.
