Description

[Detailed description of the invention] This invention is a grain culm bundle collection method that collects bound grain bundles in the binding part of a binder and makes it possible to release a plurality of collected grain culm bundles at once. It is related to the device.

The attachment of a grain culm bundle collection device as described above has already been proposed, for example, as seen in Japanese Utility Model Application No. 47-32839, but the conventional proposal was to collect grain culm bundles that are fed and fall. A holder that receives grain culm in a horizontal position is linked with a discharge arm of the bundling part, and when a certain amount of bundles has accumulated, the holder rotates and displaces the grain culm bundle to release it. Therefore, in order to receive the grain bundle in a horizontal position, the upper part of the receiving rod remains open.
If you try to move the accumulated grain bundles to another location and release them, there is a drawback that the grain bundles easily fall off due to the vibration of the binder machine, and if the receiving rod rotates when releasing the bundles, the next It is necessary to consider that the grain culm bundle is not sent until it is in the receiving position.

It is done as follows. That is, when the grain culms at the set location gather in the focusing passage 14 on the inner side of the door 14,
The grain culm is bound by a binding device 15,
After this bundling, the door 14 becomes in a state where it can freely rotate and the bundle discharge rod 23 is rotated for discharge, as is usual.
As seen in the figure, the grain culm bundle located between the two blades 48 and 49 is pushed out from the collection path 14 into the bundle entry path 37 by the bundle discharge rod 23 while the door 14 rotates. What will happen is that the blade 49 is pushed by this grain culm bundle, and the rotating shaft 47 and the blades 48, 49, 50, 51 are integrally moved in the direction of arrow F in FIG. 4 against the spring force of the leaf spring 54. As a result, the blades 48 push the grain bundle above the bundle discharge rod 23 and carry the grain bundle from the bundle passage 14 in cooperation with the bundle discharge rod 23. It is pushed out into the channel 37. Then, the rotating shaft 47 and the blade 4
8, 49, 50, and 51, when the rotation is performed by 90 degrees, the leaf spring 54 is rotated by the rotation regulating body 5.

Due to the rotation of 51, the bundle storage section 43 is pushed by the blade 49.
The grain culm bundles that have been transferred into the expanded front end 43a of the bundle storage section 43 due to the previous rotation of the blades 48, 49, 50, and 51 are Feathers 48, 49, 50, 51
Due to the rotation, the blade 50 pushes the bundle into the space between the shutter 40 and the bundle pressing body 42 in the bundle storage section 43.

In FIG. 1, reference numeral 55 designates a pair of right and left grass dividers installed at the front end of the reaping binding unit B, and 56 represents a side divider installed on the unmown side of the reaping binding unit B. Further, in FIG. 2, 58 is a sled body installed on the bottom surface of the bottom plate 29 of the main frame 26, and this sled body 58
is supported by the bottom plate 29 at its front end so as to be rotatable around a horizontal pivot shaft 59, and
The rear end portion is supported by a spring mechanism 60 so as to be elastically movable up and down.

The grain culm bundle collecting device C as described above is attached to one side of the binder, and the binding case 21 of the binder is attached using the above-mentioned attachment part 27 and fastener 28, and the grain bundle collecting device C is attached to the side of the binding device 15 as shown in the figure. When reaping work is carried out in a field by installing the reaping device vertically from the side to the side of the drive wheel 3, the following effects are achieved.

That is, although the grain culm reaping and binding action by the illustrated binder is as described above and as usual, the reaped grain culm pushed into the convergence passage 14 of the binding device 15 by the packer operation reaches a predetermined amount. The door 24, which also serves as a sensing device, detects that the grain has accumulated in the converging passage 14, and the needles and knotting section 22 of the concentrating section 25 are activated to bind the grain culms.
Next, when the grain culm bundle is sent out by the discharge rotation of the bundle discharge rod 23, as described above, the grain culm bundle located between the two blades 48 and 49 of the auxiliary conveyance device as seen in FIG. The bundle is simultaneously pushed by the vanes 48 at a position above the bundle discharge rod 23 and delivered to the bundle entry path 37. In this way, the grain culm bundles are pushed and sent out at two locations, upper and lower, by the bundle discharging rod 23 on the stock side and by the blades 48 on the supplementary tip side, so that the grain culm bundles have a vertical appearance after tying. The bundles are sent out into the bundle entry path 37 in an orderly manner. Next, the grain culm bundle is rotated intermittently at 90 degrees by the intermittent discharge rotation of the bundle discharge rod 23 caused by the intermittent operation of the binding device 15, as also described above. Since it is moved, as seen in Figure 4, the blade 4
The grain culm bundle located between 9 and 50 is pushed by the blade 49 into the expanded front end 43a of the bundle storage section 43, and the grain culm bundle located between the blades 50 and 51 is pushed by the blade 50 and bundled. The shutter 40 is sent to the installation position in the storage section 43 in an upright position. In this way, the grain culm bundles are sequentially fed into the bundle storage section 43 in an upright position, so that within the bundle storage section 43, the grain culm bundles fed first are pushed by the following grain culm bundles. Then, the bundle pressing body 42 is retreated inwardly against the force of the compression spring 46, and while pushing and expanding the bundle storage section 43, it moves to a rear position in the bundle storage section 43, and the bundle is pushed out. A plurality of grain culm bundles are collected in the storage section 43 in a vertical manner in series along the longitudinal direction of the machine, and in the case shown in the figure, are elastically clamped between the shutter 40 and the bundle pressing body 42 by the action of a compression spring 46. It is.

When the set number of grain bundles have been collected in the bundle storage section 43, or when the reaping work with the binder has been carried out to the furrow, the shutter 4
0 is flipped up and rotated around the pivot shaft 39 by operating the operating rod 41, brought to a tilted posture as shown in the imaginary line in FIG. 2, and the bundle discharge port 38 is opened. The multiple grain culm bundles that were lined up in a row are neatly released sideways while maintaining the front and back series. After releasing the bundle, the shutter 40 is returned to its original horizontal position by operating the operating rod 41 to close the bundle discharge port 38 again.

As is clear from the above description, the grain culm bundle collection device in the binder of this invention is equipped with a grain culm bundle collection device capable of storing a plurality of grain culm bundles in an upright position on one side of the binder body, and The front side of the device is configured as a bundle entry path communicating with the collection path of the binding device, the rear side of the collecting device is configured as a bundle storage section for grain culm bundles, and the already cut field side of the bundle storage section is configured in an open state. The opening portion is provided with a shutter that opens and closes by rotating in the vertical direction, and a pressing body whose tip protrudes into the bundle entry path and is bent inward. Because it is a thing, it has the following effects.

When the grain culm bundles stored in the grain culm bundle collecting device are full, the reaping operation is stopped and the grain culm bundles are collected in one place by transportation, or when the grain culm bundles stored in the device are not yet full and the When moving to the next field after reaping work is finished, the bundles can be transported while being held in the storage compartment by a shutter and a pusher to prevent the bundles from falling out of the device even if the binder body vibrates. .

The release of grain culm bundles is not done by rotating the entire device as in conventional systems, but by rotating the shutter, which is a part of the bundle storage part, in the vertical direction, in other words, the grain culm bundles are released and tilted. Since the shutter is operated in a direction different from the direction in which the binder is moved, the shutter that opens and closes does not protrude to the side more than approximately the same amount as the collection device's protrusion to the side of the binder body. There are no problems caused by large changes in the degree of discharge, and because of the above-mentioned operating direction, the bundle can be separated smoothly during discharge, and the shutter can be quickly returned to the blockage receiving position after discharge. Therefore, the grain bundles after being released can be placed horizontally in an orderly manner.

The collecting device of the present invention is applied to the flow of grain culm bundles.
When the grain culms in the bundle storage section are separated into the bundle entry path and the bundle storage section, and the grain culms in the bundle storage section are released using a shutter and a pushing body, the inwardly bent tip of the pushing body temporarily collects the bundles in the bundle entry path. As a result, collection work can be carried out continuously regardless of the release of grain culm bundles.
