Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a mounting structure for a reaping device installed in a reaping/harvesting machine such as a combine or a binder. The present invention relates to a mounting structure for a reaping device of a reaping harvester, which is removably connected horizontally to frames located at both ends of the width.

[Conventional technology]

In a conventional mounting structure for a reaping device, the blade rest of the reaping device is installed across the left and right frames, and both ends of the blade rest are bolted to the frame. Therefore, when installing the reaping device between both frames, conventionally the reaping device is installed between the left and right frames, and then both ends of the blade rest are lifted by hand by the operators on both sides. Both ends of the blade stand were bolted to both frames while being supported parallel to the ground.

Similarly, when repairing or inspecting the reaping device, if you remove the bolts from one end of the blade stand, the load of the reaping device will act on the connecting part of the blade stand on the other side, causing the parts to deform. Because of this, workers on both sides remove the bolted parts at both ends of the blade stand from the frame at the same time to remove the entire reaping device from the machine.

[Problem that the invention attempts to solve]

As mentioned above, two workers must work together to install and remove the reaping device, and the bolt fixing positions must be mutually adjusted, making installation difficult. It is inferior;
Moreover, such a reaping device may be accidentally dropped, which may damage the blade and is dangerous.

The present invention has been developed in view of the above-mentioned circumstances, and aims to provide a device that can be installed relatively easily and safely by just one worker.

[Means for solving problems]

That is, the characteristic configuration of the mounting structure of the reaping device of the reaping harvester according to the present invention is such that one end of the blade stand is attached to the frame on one side so as to be vertically swingable about the longitudinal axis. It is removably connected to the connector, and the other end of the blade stand is removably attached to the other frame, and its functions and effects are as follows.

[Effect]

When installing the reaping device between the left and right frames, lift one end of the blade stand while supporting the other end of the blade stand on the ground, and attach it to one frame so that it can swing vertically. Connect to the connector. Then, the other end of the blade holder is lifted, the blade holder is rotated upward about the connector, and the other end of the blade holder is bolted to the other frame. In addition, when repairing or inspecting the blade stand, remove the bolt fixing part on the other end,
This is done by rotating the blade holder upward about the connector, supporting the other end of the blade holder on the ground, and keeping the blade holder slanted.

[Effect of idea]

As mentioned above, one end of the blade stand can be supported on the ground, so even one worker can install or remove it, and even adjust the bolt fixing position. Since only one end needs to be adjusted, installation is now easier. Furthermore, there is no need to drop the blade rest to the ground, there is no risk of damaging the blade body, and the blade can be installed safely.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Fig. 3 shows a plan view of a clipper type reaping device A installed on a combine harvester. It is configured to be driven via a push/pull rod 9 and a swing arm 10 that are reciprocated by power from an engine (not shown).

To explain the structure of the clipper type reaping device A, as shown in FIG. In addition to stopping and fixing them side by side, the knife bar 3, which is long in the lateral direction of the machine, is installed.
A large number of cutting blades 4 are riveted and fixed in parallel to the lower surface of the knife bar 3, and the knife bar 3 is slid in the longitudinal direction onto the receiving blade stand 1 with the upper surface of the receiving blade 2 and the lower surface of the cutting blade 4 in close contact with each other. In addition to being movably mounted, the blade rest 1
It is constructed by fixing an elastic knife clip 5 to the upper surface of the knife with bolts. A knife head 11 is attached to the upper surface of the knife bar 3,
The driving side end of the swing arm 10 is inserted into and removed from the insertion groove 8 formed in the knife head 11, and the knife bar 3 is reciprocated along the longitudinal direction by the reciprocating drive of the push-pull rod 9. This allows grain culms to be cut between the receiving blade 2 and the cutting blade 4.

Next, the mounting structure of the clipper type reaping device A having the above configuration will be explained in detail. As shown in FIG. The connecting plate 12 of No. 6 is pivotally supported to be vertically swingable about the longitudinal axis of the machine body, and one end portion of the blade stand 1 of the hair clipper type reaping device A is detachably connected to this connecting plate 12. There is. That is, a connecting pin 13 is protruded from the upper surface of the connecting plate 12, and a connecting hole 14 drilled at the end of the blade stand 1 is inserted into the connecting pin 13 so as to be freely inserted and removed from above. The connecting pin 13 is prevented from coming off by a beta pin 15 inserted through the upper end of the connecting pin 13. Therefore, the blade rest 1 can be vertically swung around the front and back axis around this connector 6, and the mounting portion 16 bent at the other end of the blade rest 1 is fixed to the frame 7 on the other side with bolts.

When the reaping device A is mounted horizontally between the frames 7, 7 as described above, the drive side end of the swing arm 10 is inserted into the insertion groove 8 of the knife head 11. It's becoming like that.

According to the above configuration, when repairing or inspecting the reaping device A, only one end of the blade rest 1 is removed from the frame 7.
Since it is only necessary to remove the reaping device from the reaping device, cleaning etc. can be easily performed, and even if the reaping device A is heavy, it can be attached and detached relatively easily and safely.

[Another example]

The hinge 6 is constructed so as not to rotate beyond a set angle, and the connecting pin 13 is inserted into the connecting hole 14 of the blade holder 1, thereby connecting the connecting plate 12 and the blade holder 1. In this case, the connecting plate 12 and the blade rest 1 are connected substantially linearly by the fitting between the connecting pin 13 and the connecting hole 14.
The blade holder 1 will not come off the connection plate 12.

Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
