Description

[Detailed Description of the Invention] The present invention includes a pulling device, a reaping device, a device for transporting the harvested stalk culm by locking it to one side of the machine body, and a device for transporting the harvested stalk culm at the lifting end of the pulling device. The present invention relates to a reaper equipped with a rotary pucker that scrapes into the transport path of a lateral transport device.

In the conventional reaper, the lifting end side rotating shaft of the pulling device extends upward, and the rotary pucker is fixed to this extended shaft portion, and the rotary pucker is connected to the locking pawl of the horizontal conveyance device. However, in this case, the transmission structure for the lifting device and the rotary puller can be easily and economically configured using a horizontal conveying device. However, since the lifting device is disposed at the bottom of the rotary packer, the following drawbacks arise.

In other words, if the lifting claw of the lifting device is made longer, it will interfere with the constituent members of the horizontal conveyance device, so it is not possible to make the lifting claw as long as the left, and as a result, the lifting performance and the horizontal conveyance from the lifting device are There was a drawback that the performance of transferring the stem culm to the device deteriorated.

The purpose of the present invention is to improve the above-mentioned drawbacks by rationally modifying the lifting device, the rotary packer, and the lateral conveyance device, and to achieve the purpose. The characteristic configuration made for this purpose is to extend the lifting end side rotating shaft of the lifting device downward, fix the rotating packer to this extended shaft portion, and connect the rotating packer to the lateral conveyance device. The main feature is that it is configured to be driven by engagement with a stopper.

The functions and effects of the above characteristic configuration are as follows.

In other words, while the transmission structure for the lifting device and the rotary packer can be configured simply and economically by using the horizontal conveyance device, since the lifting device is located above the rotating packer, the lifting device can be easily and economically constructed. There is no interference between the claws and the components of the horizontal conveyance device, and the length of the lifting claws can be freely set according to various lifting conditions, conditions for transferring stem culms from the pulling device to the horizontal conveyance device, etc. be able to.

Therefore, by simply modifying the lifting device, the rotating packer, and the horizontal conveying device as described above, it is possible to improve the lifting performance and the performance of transferring stem culms from the lifting device to the horizontal conveying device. We were able to achieve this.

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

As shown in Figures 1 and 2, the front part of the machine body A is equipped with a steering handle 1 and one propulsion wheel 2, and a pair of left and right grounding radials 3, 3, which can be raised and lowered and fixed, is installed on the front part of the machine A. Part B is connected to form a walking type reaper.

The body A is constructed by directly connecting an engine 4 and a transmission case 5 side by side on the left and right, and attaching the handle 1 and the reaping frame 7 of the reaping section B to cylindrical frames 6, 6 extending forward from these, respectively. In addition, a transmission case 8 that pivotally supports the propulsion wheel 2 is attached to the transmission case 5 so that it can be vertically swung and fixed in a state where the propulsion wheel 2 is located between the cylindrical frames 6, 6. It is set up in

The reaping section B is constructed as follows.

That is, as shown in FIGS. 8 to 5, a device 10 for pulling up a plurality of planted stem culms to be reaped is arranged at the front end of the reaping frame 7 in an inclined position from the lower front to the upper rear. and this lifting device 1
At the rear of the 0, there is a clipper type reaping device 11 that cuts the base side of the planted stem culm that has been raised to an upright position, and a clipper type reaping device 11 that cuts the stem side of the planted stem culm that has been raised to an upright position, and a clipper type reaping device 11 that cuts the stem culm by rotating the locking claws 12a, 12a horizontally or within a substantially horizontal plane. Upper and lower two-stage horizontal conveying devices 12, 12 are provided for locking the tip side and stock side, respectively, and transporting and discharging them to one side of the machine body, and a lifting end of the lifting device 10 is provided. At the bottom, there is a star wheel-shaped rotary packer 1 that scoops the harvested stem culm into the transport path of the horizontal transport devices 12, 12.
3 is arranged in the same or almost the same forward downward tilting posture as the lifting device 10.

Then, the lifting terminal end rotating shaft 14 of the lifting device 10 is extended downward, and the rotary packer 13 is engaged with the locking pawl 12a of the upper lateral conveying device 12 at this extended shaft portion. The transverse conveying devices 12, 12 are connected to each other from the transmission case 5 through a shaft transmission device and a chain transmission device 15 (not shown) installed in one of the cylindrical frames 6. It is configured to transmit power to the common input shaft 16 of the.

The locking pawl 12a of the upper lateral conveyance device 12 is configured to be in a downwardly inclined forward direction substantially parallel to the rotary packer 13.

The support frame 20 of the lifting device 10 and the rotary packer 13 is configured to be vertically swingable and fixed to the reaping frame 7 around a horizontal axis P on the lifting end side of the lifting device 10. . By vertically swinging the support frame 20, the position of the lifting start end of the lifting device 10 relative to the reaping device 11 can be freely changed. In other words, while cutting at a constant or almost constant length from the tip regardless of the culm length of the planted stem culm, it is possible to freely change the position of the starting point by raising it depending on the degree of lodging of the planted stem culm. .

The lifting device 10 is constructed as follows.

That is, the pulley 2 fixed to the rotating shaft 14
1 and a pulley 22 pivotally supported at the lower part of the support frame 20, an endless belt 24 having a plurality of lifting claws 23 is hung, and the lifting claws a portion 25a that guides the raising action of the planted stem culm by the claw 23;
26a, and guide portions 25b, 26b that prevent the pulling action of the adjacent planted stem culm from being obstructed by the pulling claw 23 that moves back. , the lifting guide portion 26a of the lower guide rod 26 is made to protrude further outward than the lifting guide portion 25a of the upper guide rod 25.
