Description

[Detailed Description of the Invention] The present invention relates to a culm conveying device that is attached to the culm discharge position of a knock (tying device) attached to the rear of the threshing section of a self-propelled combine harvester.

As this type of combine harvester, one is known in which the waste culm is bundled into a predetermined size and discharged into the field for recovery in order to use the waste culm for pulling processed products. The bundled culm bundle is discharged to the rear side of the combine harvester by a discharge device so as not to interfere with the harvesting operation of the combine harvester.

This culm bundle discharge device is composed of an endless discharge belt and a guide rod, and is attached to the frame of the knotter, and a transmission system independent from the passive part of the knotter is used to transmit the power of the discharge belt. Therefore, there was a problem that the mechanism was large and complicated.

Therefore, in consideration of the above-mentioned circumstances, the present invention solves the above-mentioned problems by making it possible to construct a compact culm bundle discharging device, and also to allow it to be easily positioned in the discharging culm bundle discharging device of a knotter. It is an object of the present invention to provide a discharged culm bundle discharge device.

For this purpose, the present invention connects the discharge belt to one end of a rotary shaft supported by a support block of the notter, connects it to one end of the rotary shaft, and connects the discharge belt to one end of the rotary shaft from the constantly rotating shaft of the notter. It is characterized by transmitting rotational power.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

In the figure, reference numeral 1 denotes a self-described combine harvester, and this combine 1 has a crawler belt 3 at the bottom of a car body 2, a reaping part 4 at the front of the waist car body 2, and a threshing part 5 at the rear thereof. ing.

A knock 7 is installed at the rear of the threshing section 5 to bind the shed culms that have been threshed by the threshing section 5 and transported laterally in a substantially horizontal position by the discarded culm conveying device 6.

As shown in FIGS. 3 and 4, the knock-7 is located above the converging section 8, which collects and converges the culms sent from the culm conveying device 6 in the same position, and the converging section 8. , focusing section 8
and a bundling part 9 arranged at a predetermined interval, the bundling part 8 is provided with a packer 10, a needle 11, a T-shaped protrusion 12, etc. A holder (not shown), a release arm 14, etc. are provided.

The converging part 8 and the binding part 9, which extend flat in the width direction of the body, are connected and supported by a frame 15 at the negative end and by a connecting pipe 16 at the other end.

In addition, an endless release belt 17 is provided at the rear of the knock-7.
A culm type discharge device 19 consisting of a guide rod 18 and a guide rod 18 is attached.

The culm type discharge device 19 is attached to the knotter 7 as described below.

That is, a support block 20 whose one end is fixed to the frame 15 is fitted onto the shaft 12a of the T-shaped projection 12, and a bearing 21 is fixed to the support block recess 20 in parallel with the shaft 12a.
A rotating shaft 22 is pivotally supported.

Further, a bearing 23 is fixed to the support block 20 in a direction oblique to the rotating shaft 22, one end of a rotating shaft cover 24 is fixed to the bearing 23, and a clutch cover 25 is fixed to the other end of the rotating shaft cover 24. is fixed.

A rotating shaft 27 with a clutch pawl 26 fixed to one end is inserted through the bearing 23, rotating shaft cover 24, and clutch cover 25, and the other end and one end of the rotating shaft 22 are connected by a universal joint 28. A chain transmission system 29 is provided between the other end of the rotating shaft 22 and the shaft lea of the packer 10.

Further, on the outside of the clutch cover 25, a support member 17a, which also serves as a bearing for the agitation shaft 30 of the discharge belt 17, is rotatably attached by a pin 31.

Furthermore, a pole stopper 32 is provided on the outside of the clutch cover 25 on the side opposite to the pin 31 side, and the pole stopper 32 is in sliding contact with the pole stopper 32 .
An elastic plate 35 having engagement holes 33 and 34 at several locations is attached with two bolts 36.

On the other hand, a clutch pawl 37 that meshes with the clutch pawl 26 is attached to the driven end of the drive shaft 30 .

Then, when the release belt 17 is rotated around the pin 31 and moved in the direction in which the clutch pawls 26 and 37 are separated,
The pole stopper 32 and the retaining hole 33 are engaged to make a click stop, and the release belt 17 is stored in a position almost parallel to the knock-7, and the release belt 17 is connected to the clutch pawl 26.
When the and 37 move in the direction of engagement and engage, the pole stopper 32 and the engagement hole 34 engage and click stop, and the discharge belt 17 protrudes obliquely to the knock 7. It has become.

In such a configuration, when the combine harvester 1 is introduced into the field and harvesting work is performed, the discharge belt 17 is moved to the working position,
That is, when the pin 31 is rotated and the pole stopper 32 and the engagement hole 34 engage with each other to project to a click stop position, the clutch pawls 26 and 37 are engaged (FIG. 7b).
The rotational power of the packer shaft 10a is transmitted to the rotating shaft 22 via the chain transmission system 29, from the rotating shaft 22 to the rotating shaft 27 via the universal joint 28, and further from the clutch pawl 26.37 to the drive shaft 30. Release belt 1
7 in a predetermined direction.

The culm bundles bound by the knocks 7 and discharged to the culm bundle discharge device 19 side by the discharge arm 14 are held between the discharge belt 17 and the guide rod 18, and are transferred to the combine harvester on the rear side of the machine. Release it to the side where it will not interfere with the next reaping process.

At this time, the culm type discharging device 19 is located immediately after the culm bundle discharging device of the knotter 7, and its support device and power transmission mechanism are located in the converging section 8, so that the conventional frame 1
The configuration is simpler than that extended from 5, and the culm bundles can be taken over reliably.

In addition, when the combine harvester 1 is not performing harvesting work and is running on the road, transporting, storing, etc., the release belt 17 is connected to the pin 31.
When the pole stopper 32 is rotated around the center and placed in the storage state, the pole stopper 32
The engagement holes 33 are engaged as shown in FIGS. 5 and 6, and the clutch pawls 26 and 37 are separated (FIG. 7a), power transmission is cut off and the drive of the discharge belt 17 is stopped. However, the discharge belt 17 is stored parallel to the knock-7.

As explained above, according to the culm type discharge device of the present invention,
The culm type discharge device can be easily incorporated into the knotter.
Moreover, the transmission to the device is received from the knotter without providing a separate transmission system, resulting in a short overall length, light weight, and compactness, making it suitable for mounting on a combine harvester or the like.
