Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a grain culm binding device, and is particularly applicable to a reaping binding machine or a binding machine for a combine harvester.

[Prior art]

In the conventional structure, for example, as shown in Japanese Utility Model Publication No. 52-34267, a needle passage hole is formed in the side wall constituting the binding passage, and an elastic body is attached to the periphery of this passage hole. During the string winding process, the grain culms that are about to be brought into the binding device by the needles are received by the elastic member.

[Problem that the invention seeks to solve]

The present invention relates to an improvement on the conventional type described above, in which a platform having a weakened strength due to the formation of a needle passage hole is replaced by a raised edge provided on both sides of the passage hole and a grain culm feeding platform. The protruding edges on the sides are made to protrude vertically and horizontally in a rib-like manner, and are integrally constructed and reinforced to realize a highly durable platform. The purpose of this is to prevent unfocused grain culms from being dragged in by the back side of the needle by the protruding edge that also serves as reinforcement.

In particular, in this invention, the protruding edge acts on the needle at a position where the grain culms to be focused in the focusing passage are moved away from the passage hole (platform) and closer to the focusing passage, so that there is a gap between the grain culm group and the passage hole. The purpose is to create a space and effectively prevent the grain culm from being brought into the knotting mechanism.

[Means to solve the problem]

The present invention uses the following technical means to achieve the above object.

That is, a knotting mechanism consisting of a string holder 2 and a building 3 is provided on one side of the focusing passage 1, and a needle 5 and a knotter 10 are provided on the other side, and the needle 5 is provided between the focusing passage 1 and the knotting mechanism. A platform 4 having a passage hole 6 is provided, and at least both sides of the passage hole 6 of the platform 4 are provided with rising edges 17 extending in the longitudinal direction in order to move grain culms away from the passage hole 6 toward the concentrating passage 1 side. established,
The rising edges on both sides are integrally connected by a protruding edge that protrudes to a position apart from the surface of the platform on the grain culm feeding side, and the protruding edge is located on the back side of the needle operating locus. This is the constructed grain culm binding device.

[action, effect]

First, the grain culms are continuously supplied from the supply side of the focusing passage 1, and are successively focused toward the T-protrusion 9 by the packer 10, which repeats the compression operation.

In this way, when the grain culm reaches a certain amount in the convergence passage 1, it presses the T-protrusion 9 to actuate it and engage a binding clutch (not shown).

Then, each part starts operating at a certain timing, but first, the needle 5 starts rotating in order to wrap the binding string around the grain culm, crosses the collection path 1 and passes through the platform 4. The binding string is supplied through the hole 6 to the knotting mechanism consisting of the building 3 and the string holder 2.

Then, the grain culms are bound by the actuation of the bill 3 and the string holder 2, and are discharged from the focusing passage 1 to the outside of the machine by the rotating discharge arm 13.

During this series of actions, the needle 5
In the process of winding the string described above, the string enters between the grain culm in the condensed state and the grain culm on the feeding side and separates.

At this time, the grain culm on the back side of needle 5 is
It moves in the direction of the platform 4 along with the rotating needle 5, but the distance from the passage hole 6 is 16
Movement is prevented by the protruding edge 8 that protrudes toward the focusing passage 1 side across from the center, so that it almost never reaches the passage hole 6.

In particular, according to the configuration according to the present invention, even if the grain culm that is being moved toward the back side of the needle 5 cannot be completely stopped by the protruding edge 8, the protruding edge 8
Since there is a gap 16 between the protruding edge and the passage hole 6, the protruding edge is characterized in that it does not immediately reach the knotting mechanism.

Furthermore, although the strength of the platform 4 is inevitably weakened by forming the passage hole 6, the rising edges 17 in the longitudinal direction provided to keep the focused grain culms away from the grain culms that are brought into the platform 4. Since the protruding edge 8 provided in the lateral direction to prevent this is integrally constructed, the device is significantly reinforced and can be put to practical use.

〔Example〕

In the drawing, the focusing passage 1 is composed of a platform 4, a guide wall 11 provided on the knotting mechanism side so as to be continuous with the platform 4, and a grain culm guide wall 12 provided opposite thereto.

A string holder 2 and a billet 3 constituting a knotting mechanism are provided on one side of the focusing passage 1, and a needle 5 and a stringer 10 are provided on the other side of the focusing passage 1, respectively. Each of these mechanisms is connected to the transmission frame 14.
It is mounted on a shaft.

The platform 4 is provided with a passage hole 6 through which the needle 5 passes, as shown in FIGS. 2 and 3.
On both sides thereof, there are provided rising edges 17 extending in the longitudinal direction of the focusing channel 1 .

Incidentally, the rising edges 17 are raised so as to keep the grain culms as far away from the platform 4 as possible, and in the case of the embodiment shown in the drawings, three rising edges 17 are provided as shown in FIG. 3.

The projecting edge 8 is provided at the starting end of the platform 4, that is, at the entrance side of the convergence channel 1, so as to project laterally toward the channel 1, and integrally connects the ends of each of the rising edges 17. It is composed of

The tip end 7 of the protruding edge 8 is located close to the back surface operating locus of the needle 5.

Reference numeral 9 denotes a T projection, which is attached to the end of the focusing passage 1 by a shaft 18, and when a certain amount of grain culm is collected in the focusing passage 1, it is slightly pushed backward by the pressing force, and the binding clutch is (not shown).

13 is a discharge arm, 15 is a guide surface of the platform 4, 16 is a spacing part, 19 is a link mechanism of the packer 10, and 20 is a needle shaft.

With the above structure, when grain culms are fed into the convergence passage 1, the grain culms are compressed toward the T-protrusion 9 by the packer 10, which repeats the compression operation, and are successively converged.

Then, when the amount of grain culm reaches one bunch,
Press the T projection 9 to engage the binding clutch.

Next, the needle 5, string holder 2, building 3, and discharge arm 13 each operate at a certain timing to wrap the binding string around the gathered grain culms as described above to bind them. release it outside.

During such a bundling action, the grain culm that is being brought to the platform 4 side by the back side of the needle 5 is caught by the tip edge 7 of the projecting edge 8.

However, all of the grain culms carried in the direction of the passage hole 6 are not completely blocked by the protruding edge 8, but because there is a gap 16 between the leading edge 7 and the passage hole 6, , when it reaches that part of space, it becomes free.

Therefore, when the grain culm that is about to be brought in reaches the gap 16, it is released from the action of the needle 5, and the grain culms that are about to be taken in are released from the action of the rising edges 17 on both sides to move towards the focusing passage 1 side. returned.
