Description

[Detailed Description of the Invention] The present invention relates to a culm raising and weeding device in a reaper suitable for use in a reaping section of a combine harvester, a binder, or the like.

As this type of reaper, it is installed upright at the front of the machine in a backward-slanted manner.
a shell culm lifting mechanism having a lifting claw that lifts in a direction intersecting the direction of movement of the aircraft; and a lifting mechanism on the side of the shell culm lifting mechanism that lifts in a direction parallel to the direction of movement of the aircraft. Some are equipped with a culm raising weeding mechanism having weeding claws.

and. Usually, the shell culm raising weeding mechanism protrudes slightly forward with respect to the shell culm pulling mechanism and is configured to have a low height.

For this reason, if the culms to be harvested are short and have little lodging, there is no problem; however, if the culms are long and have a lot of lodging, the uncut culms that cannot be completely separated by the culm lifting and weeding mechanism may cause problems. The sugar part of the culm on the culm side is introduced into the culm reaper, which is entangled with the sugar part of the culm pulled up by the culm lifting mechanism, and the lifting claw of the culm lifting mechanism is lifted up, and the culm is removed from the stock. The grains are harvested by a cutting blade and transferred to a threshing section by a conveying device, for example in the case of a combine harvester, where they are squeezed and sloughed, resulting in losses as they fall onto the field.

Spread. The uncut culms were pulled toward the threshing section, which sometimes caused problems with the harvesting process.

Therefore, in the present invention, the height of the culm pulling mechanism is set higher than the height of the culm pulling mechanism, and even if the culm to be harvested is long and often lodged, the culm The uncut culm is completely pulled up and separated from the uncut culm by being pulled up by a pulling mechanism and introduced into the reaper, and the sugar part of the uncut culm is introduced into the reaper with the sugar part of the uncut culm entwined with the sugar part of the hull culm to be harvested. The present invention provides a culm raising and weeding device for a reaper that eliminates the problem of grass culling.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a reaping part of a combine harvester. At the front part of this reaping part 1, there are a number of lifting claws 2a that are pivotably supported on an endless belt so as to be able to be raised and lowered, and that lift up in a direction perpendicular to the direction of movement of the harvester. ,
A pair of left and right shell culm lifting mechanisms 2 having 2a... are provided.

On the side of the shell culm pulling mechanism 2, at a position corresponding to the intermediate position between the row of shell culms pulled up by the sword fighting pulling mechanism 2 and the uncut culm rows, there is a pivot support that can be raised and lowered into an endless belt. A large number of lifting separation claws 3a, 3 extend upward in a direction Km parallel to the direction of movement of the aircraft.
A shell culm lifting and separating mechanism 3 having a... is provided.

The height of this culm lifting and separating mechanism 3 is determined by the height of the culm lifting device 2.
As shown in FIG. 2, it is higher by H than the height of .

Below the shell culm pulling mechanism 2 and the shell culm lifting and weeding mechanism 3, there are three weeding bodies 4 that protrude forward of the machine body and weed the shell culm rows, as shown in FIG. One of them is directly attached to the lower part of the culm lifting and weeding mechanism 3.

A cutting blade 5 is provided at the lower rear of the culm lifting mechanism 3, and above the cutting blade 5, a conveyor is provided which holds and conveys the culm cut by the cutting blade 5 and supplies it to the threshing section I. A device 6 is provided.

Next, the operation of the above embodiment will be explained.

The combine harvester is run along the planting row of the culms to be harvested. The grain is introduced into the reaping section 1, the cutting blade 5 cuts off the edge of the stock, the base of the stock is scraped, the grain is conveyed by the conveying device 6, and then supplied to the threshing section 7 where it is threshed.

In addition, in the culm pulling mechanism 3, the culm that is raised by the culm lifting mechanism 2 and cut by the cutting blade 5 and the uncut culm are completely separated while being raised.

At this time, especially if the grain culm to be harvested is a long culm and there is a lot of lodging, the shell culm is pulled up, making the weeding (separation) work difficult. Since the height of culm 3 is higher than the height of the culm pulling mechanism 2 by H, the culm that has been completely separated from the uncut culm by the culm lifting mechanism 3 is removed by the culm lifting mechanism 2. It will be introduced into the reaping section 1.

Therefore, the uncut culms are not completely separated as in the conventional method.
2. The sugar part of the uncut culm introduced into the reaping part 1 is prevented from being shed by straining or causing chopping during harvesting, reducing losses and improving work efficiency.

As explained above, according to the shell culm pulling and weeding device of the present invention, the height of the shell culm lifting and weeding mechanism is higher than the height of the shell culm pulling mechanism. The culm that is raised by the culm lifting mechanism and introduced into the reaper is separated and separated from the uncut culm, and the sugar part of the uncut culm is prevented from becoming entangled and squeezed out, thereby preventing grain loss. This prevents uncut culms from becoming entangled with the reaper and does not interfere with the operation of the reaper.
