Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a manual grain bagging device used for agricultural machines such as combine harvesters and harvesters.
More specifically, the present invention relates to a grain bag filling device including a vertically expandable / contractible grain discharge cylinder that discharges grains into a grain storage bag and a shutter that manually opens and closes the grain discharge cylinder.

[Conventional technology]

Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 62-157329, the shutter and the grain discharge cylinder are mechanically linked to each other in the grain bag packing device through an exposed wire. Then, it is configured such that the lower end of the grain discharge cylinder rises with the closing operation of the shutter, and in this technique, as a means for guiding the wire, near the center portion in the width direction of the grain discharge cylinder. There was only a small diameter roller provided.

[Problems to be Solved by the Invention]

In the above-mentioned conventional grain bag packing device, the shutter and the discharge cylinder are mechanically interlocked with each other via a wire, and the lower end of the grain discharge cylinder is raised with the closing operation of the shutter. Therefore, when taking out a storage bag full of grains, it can be taken out after raising the lower end of the grain discharge cylinder, and the storage bag can be removed like when the discharge cylinder was a fixed cylinder, for example. There is no need to go under the bottom of the cylinder,
There is an effect that it is possible to avoid spilling of the grain when passing through such a way.

However, according to the above-described conventional configuration, as a means for guiding the wire, there is only a small-diameter roller provided near the center in the width direction of the grain discharge cylinder,
The wire bent in a sharp curve, and the resistance to movement of the wire increased, requiring a large amount of force to close the shutter.

In addition, a stopper portion that determines the lowermost position of the grain discharge cylinder due to the fact that the wire is exposed and that there is only a small-diameter roller for guiding the wire as described above. Moreover, when providing the stopper portion that determines the maximum pushing position of the shutter, it is necessary to newly form them as separate members, and the number of parts is increased and the structure is complicated.

An object of the present invention is to make it possible to perform a shutter closing operation with a light force, and further, a stopper structure that determines the lowermost position of the grain discharge cylinder and a stopper structure that determines the maximum pushing position of the shutter have a simple structure. Is to be able to.

[Means for solving the problem]

A characteristic configuration of the grain bagging apparatus according to the present invention is that the shutter and the grain discharge cylinder are mechanically interlocked and coupled via a wire guided by a wire guide, and the grain is accompanied by a closing operation of the shutter. The lower end of the grain discharge cylinder is configured to rise, and in configuring the wire guide, one end side is in the opening / closing direction of the shutter, and the other end side is along the vertical expansion / contraction direction of the grain discharge cylinder, and an intermediate portion. Is formed in a state along a curved line that is smoothly in contact with the opening / closing direction of the shutter and the vertical expansion / contraction direction of the grain discharge cylinder, and the one end portion is the first bulge portion on the corresponding one end portion side of the wire. The second bulge on the other end side of the wire, which can be abutted and is formed on the first stopper portion which determines the lowest position of the grain discharge cylinder by the abutment. You can contact the department, One lies in the fact that is formed in the second stopper portion that determines the maximum push-in position of the shutter by the Setto.

[Work]

According to the above configuration, it is possible to raise the lower end of the grain discharge cylinder with the closing operation of the shutter. in this case,
Since the wire guide is bent as described above,
The wire bends in a gentle curve to reduce the movement resistance of the wire.

Further, by effectively utilizing this wire guide, both ends thereof are separately formed as a stopper portion that determines the lowest position of the grain discharge cylinder and a stopper portion that determines the maximum pushing position of the shutter. It is not necessary to newly form both stopper portions as separate members, and it is possible to suppress an increase in the number of parts.

〔The invention's effect〕

Therefore, the movement resistance of the wire can be reduced, the shutter closing operation can be performed with a light force, and further, the stopper structure that determines the lowermost position of the grain discharge cylinder,
The stopper structure that determines the maximum pushing position of the shutter can be made simple.
