Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a case body in which a stem culm raising case is rotatably driven by a chain in which a stem culm locking claw is pivotally swingable And a stem culm raising device constituted by a cover case part which is detachably attached to the case body while the front surface of the case body covers the wales.

[Conventional technology]

Conventionally, as a stem culm raising device of this type, for example, as disclosed in Japanese Utility Model Laid-Open No. Sho 64-22232, a boss integrally provided with a pin integrally provided on a cover case portion is provided on a case body. Maintenance work in the case by raising the stem culm by preventing the pin from coming off by engaging the engaging member with the pin tip in the state of being fitted to the boss part It is known that the cover case portion can be easily attached to and detached from the case main body when performing the above.

[Problems to be solved by the device]

However, in the above-mentioned conventional one, since the stem culm is raised and the case itself is a long product, it is not necessary to hold the cover case portion of the long product and aim the pin on the boss portion for fitting. It is not easy and stable, and the removed cover case may be accidentally stepped on and damaged if placed on the ground, for example. .

The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a stem culm raising device which is extremely easy to attach and detach between the case main body and the cover case part in the stem culm raising case and is easy to manage.

[Means for solving the problem]

The stem culm raising device according to the present invention includes a case body having a stem culm raising case, a case body to which a chain having a stem culm locking claw is pivotally mounted so as to be capable of swinging, is rotatably driven, and a front surface of the case body. In a stem culm raising device composed of a cover case part that is detachably attached to the case body in a state of covering the gutter,
The cover case is swingably and rotatably connected to the case body via a hinge structure whose one side is provided in a crocodile, and the hinge structure includes a tubular collar and a tubular collar. The collar is provided with an insertable / detachable shaft body as a swing support shaft that is inserted from the cylinder axis direction, and is provided between the case body and the cover case portion. The cover case portion is engageable and disengageable in a direction in which the cover case portion moves toward and away from each other as the cover case portion swings open and close, and the position of the collar in the cylinder axis direction is regulated in the engaged state. In addition, the case main body and the cover case part are configured so that they can be connected and fixed and can be released from the fixing by fixing metal fittings each of which is provided at a position opposed to each other in an assembled state of the case main body and the cover case part. To configure

 The operation and effect of this characteristic configuration are as follows.

[Action]

That is, when the stem culm is raised to open the case for maintenance or the like, it can be easily opened by swinging the cover case part to the case body by the hinge structure.
The cover case can be connected to the case body via the hinge structure while it is left open.
The cover case can be easily closed by swinging the cover case with respect to the case body, and can be put into a normal use state by appropriately maintaining the closed state.

Further, since the hinge structure is composed of a tubular collar and a shaft body serving as a swing support shaft that can be inserted into and removed from the tubular collar in the axial direction of the cylinder, the shaft body is extracted from the collar. As described above, the cover case portion can be removed from the case body, and the cover case portion can be easily removed from the case body if necessary.

Further, the case body and the cover case portion can be engaged and disengaged in a direction in which the case body and the cover case portion move toward and away from each other as the cover case portion swings open and close, and in the engaged state, the position of the collar in the cylinder axis direction is restricted. As described above, since the case main body and the cover case portion are assembled, the fixing metal fittings each of which is provided at a position opposed to each other in the assembled state and the sandwiching and holding portion are configured so that they can be connected, fixed and released. By simply pulling the cover case part by hand, the holding of the fixing metal fittings that fasten the case body and the cover case part can be released to open the cover case part, and when closing the cover case part, simply By manually pressing the cover case against the case body, the fixing brackets are connected and fixed, so the cover case is held in the closed position. It becomes Rukoto. Moreover, when the cover case part is held in the closed posture, the position of the engaging part and the holding part of the fixing bracket is restricted in the direction in which the tubular collar having the hinge structure and the shaft body are disengaged from each other. Therefore, even if the shaft is removed from the collar during normal use, it will be restricted by the fixing brackets to prevent it from coming off. It does not come off.

[Effect of device]

Therefore, according to the present invention, it is possible to open and close the inside of the case by raising the stem culm by simply swinging the cover case portion, which simplifies the opening and closing work and even when the case body is in the open state. Since the cover case portion is still connected to the case body by the hinge structure, it is possible to eliminate the trouble of paying attention to the storage of the cover case portion.
Further, if it is desired to remove the cover case portion from the case main body, it is possible to simply remove the shaft body from the collar, and it is not necessary to use a screw like a hinge. Further, the cover case can be fixed to the case main body by the fixing metal fittings only by swinging the cover case, and conversely, the fixing can be released by manually pulling the cover case from the case main body. The simple structure is simple and the structure of the cover case can be simplified because it is not necessary to fasten the cover case to the case body, such as fastening bolts or screws or retaining pins. Therefore, the cost can be reduced. Further, even if a force acts such that the shaft body comes off the collar from the cover case portion during use, the engaging portion of the fixing bracket and the sandwiching holding portion mutually regulate the position in the axial direction of the collar, It is possible to prevent the problem that the cover case portion is unduly removed from the case body.
