Description

[Detailed description of the invention] The present invention aims to improve the steering stability of a single-wheel binder equipped with a bundled grain collection device including a collection shutter, and to rationalize the power transmission mechanism for the bundled grain collection device. This is the purpose.

The present invention is a single-wheel binder in which a single drive wheel is cantilever-supported by a drive shaft protruding from a transmission case, and is equipped with a bundled grain collecting device on the side of the machine body. established,
A clutch is used to improve the steering balance by allowing the drive wheels to move laterally in accordance with the movement of the center of gravity of the aircraft, and to control the drive device for rotating the collection shutter of the bundled grain culm collection device. The device is located on the side of the drive wheel so that it can be directly connected to the drive shaft through a pin hole and a pin, and the pin hole closer to the transmission case is selected from among the plurality of pin holes on the drive shaft to connect the drive wheel to the drive wheel. By selecting a pin hole on the outside opposite to the transmission case and installing the clutch device so that the clutch device can be attached thereto, it is possible to transmit power from the drive shaft to both the drive wheels and the clutch device.

Hereinafter, a description will be given based on the embodiments shown in the drawings.

The single-wheel binder A includes grass dividing bodies 1, 1, moving devices 2, 2, a binding device 3, a conveyance plate 4, a single-wheel drive wheel 5, an engine 6, a handle 7, a transmission case 8, a transmission case 9, etc. , mission case 8
A reaping frame (not shown) is fixed to the frame and constitutes a part of the fuselage frame, and the drive wheel 5 is cantilever-supported by a drive shaft 10 protruding from the lower part of the transmission case 8, unlike a conventional single wheel. It is similar to a binder.

The bundled grain culm collecting device B is located on the discharge side side of the binding device 3 of the single-wheel binder A.
It includes a collecting shutter 14 supported by a support rod 11 provided at the side end of the grain culm receiver 12, which collects the lower end of the stock base of the bundled grain culm P released from the tying device 3 to the side of the aircraft body.
The collecting shutter 14 supports the collecting shutter 14 and receives the tip part. Reference numeral 15 denotes a frame body for preventing the tied grain culm P from falling down to the front of the machine body or to the side of the machine body.

The collection shutter 14 includes a drive device 16,
The drive wire 17, the clutch device 18, the operating wire 19, and the lever 20 allow the driver to freely rotate the lever 20 as appropriate. That is, by operating the lever 20, the operating wire 19
The clutch body 21 in the clutch device 18 is moved to the transmission position via the drive gear 22 [drive shaft 10
] is integrated with the clutch shaft 10a that is directly connected to the drive shaft 10, and the rotational force of the drive shaft 10 is transferred to the sector gear 2 via the clutch body 21 and the drive gear 22.
3, the transmission wire 17 is pulled by the rotation of the fan-shaped gear 23, and the drive device 16 is operated. Referring to FIG. 3, the drive device 16 rotates the rotation plate 24 by pulling the drive wire 17, and engages a locking piece 26 in a recess 25a of the cam plate 25.
is moved from the recess 25a against the elastic force of the spring 27 to release the lock between the locking piece 26 and the cam plate 25, and at the same time bring the protrusion 28 into contact with the rotating plate 24 to rotate the cam plate 25. The shaft 29 integrated with the cam plate 25 and the collection shutter 14 are rotated to release the bundled grain culm in front of the collection shutter 14. After releasing the bundled grain culm, the collecting shutter 14 returns to the grain culm receiving position by the elastic force of the spring 30.

The drive shaft 10 has a plurality of pin holes 31A, 31.
B, ... and the pin 33 that has passed through the hole 32 of the boss portion 5a of the drive wheel 5 is inserted into the pin hole 31A,
Select one of 31B,... and pass through pin 3.
By attaching the locking pin 34 to the end of 3,
The drive wheel 5 is configured to be mounted on a drive shaft so that its position can be freely adjusted in the left and right direction of the machine body.

An axially cylindrical recess 35 into which the end of the drive shaft 10 can be freely inserted is formed at the end of the clutch shaft 10a of the clutch device 18, and the end of the drive shaft 10 is inserted into the recess 35. So, the clutch shaft 10a
The hole 36 passing through the end of the drive shaft 10 can be aligned with the pin hole 31A on the end side of the drive shaft 10, so that both pin holes 31
The clutch device 18 is configured to be mounted on the drive shaft 10 in a directly coupled driving state by means of a pin 33 passed through A, 36.

Note that, as a means for fixing the clutch device 18, drive wheel 5, and drive shaft 10, it is of course possible to use bolts, nuts, and other fasteners instead of the pin 33 and locking pin 34 described above. be.

When using the single wheel binder A of the present invention as a normal general single wheel binder, by selecting a plurality of pin holes 31A, 31B, ... and attaching the drive wheel 5 to the drive shaft 10, The driving wheels 5 are mounted on the fuselage body, and the mounting position can be freely changed in the left-right direction, so that the left-right weight balance of the fuselage body can always be kept good. In addition, when it is desired to select the drive wheels from one side (valley) side of the machine center line when working on sloped surfaces such as in mountainous areas, it is desirable to change the left and right positions of the other drive wheels from the machine center line. In this case, the position of the driving wheel 5 is appropriately shifted by selecting the pin hole (see FIGS. 7 and 8).

Next, when the bundled grain collecting device B is installed, as shown in FIGS. 9 and 4, the clutch device 18 is installed using the pin hole 31A on the side side, and the drive wheel 5 is installed on the inside side. Attach using pin hole 31B. Note that the pin holes 31A, 31B,...
If there are more than one mounting hole, the drive wheels 5 can be attached freely by selecting two or more mounting holes, and the left and right positions of the drive wheels 5 with respect to the machine body can be changed freely even when the bundled grain culm collection device B is installed. be able to.

The present invention provides a single-wheel binder equipped with a bundled grain culm collection device as described above, in which a plurality of pin holes are passed through the drive shaft to which the clutch device and drive wheel of the drive device of the bundled grain culm collection device can be attached. Therefore, by attaching the drive wheel to the drive shaft and directly connecting the drive device of the bundled grain culm collector to the drive shaft, both the drive wheel and the clutch device of the drive device of the bundled grain culm collector can be operated from a single transmission case. This has the effect of simplifying the power mechanism by making it possible to transmit power to.

In addition, when used as a general single-wheel binder without being equipped with a binding grain culm collection device, the mounting position of the drive wheel can be changed to the left and right of the aircraft, and the position of the drive wheel can be selected at the right and left position that is suitable for steering. This makes steering easier.
