Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a switching plate that can serve as an appropriate guide during the cutting operation of the exhaust culm, and that acts to ensure that the exhaust culm is connected to the conveying chain during the straw removal operation, and The present invention relates to a waste culm processing device and its switching operation mechanism in which the switching plate can be operated freely near the driver's seat of the combine harvester.

It is a general requirement to prevent the crawler of a combine harvester from stepping on the culms that are released uncut into the mulch during the process of harvesting standing rice by a combine harvester.

This is to collect these waste culms and use them for other purposes, but in order to do this, it is necessary to change the course of progress of the waste culms discharged from the combine harvester so that they can be used for the next reaping of the harvested field. They must be released in a position that is not directly in the path of the crawler.

Although many devices of this type have been developed in the past,
The reality is that the results are not necessarily satisfactory, and even if they are, the structure is extremely complex.

Therefore, in this invention, a culm cutter installed in the culm exit path of a combine harvester is configured with disk blades arranged at regular intervals on two parallel rotating shafts, and the cutter is extended from the culm exit of the combine above the cutter. Along with the exposed culm conveyance chain,
A first switching plate is provided with a transport guide member provided with a slight gap just below the transport chase, and a second switching plate is provided with a culm rise prevention member diagonally above and behind the cutter. This invention was developed for the purpose of providing a waste culm processing device and its switching operation mechanism that can be freely arranged and remotely operated from the driver's seat of a combine harvester.

Embodiments of the waste culm processing device and its switching operation mechanism according to the present invention will now be described based on the drawings.

Embodiment ■ This embodiment is an embodiment of the invention described in claim 1, and in the figure, 1 and 1' are two parallel wires arranged perpendicularly to the traveling direction of the culm S. It is a rotating shaft, and 2 is a disk blade fixed to the rotating shaft 1 at a constant interval.

Reference numeral 3 denotes a feed rotor provided adjacent to the disk blade 2 disposed on the rotating shaft 1, and a cutter C is constituted by these rotors.

Reference numeral 4 denotes a first switching plate rotatably disposed above the cutter C, and a conveying guide member 5 is protruded from the upper surface of the first switching plate 4.

Reference numeral 6 denotes a second switching plate rotatably disposed diagonally upwardly rearward of the cutter C, and a culm rising prevention member 7 is protruded from the lower surface of the second switching plate 6.

In the drawing, 8 is a discharge culm conveyance chain, and this conveyance chain 8 is disposed diagonally from the rear end of the feed chain 10 of the combine harvester 9 toward the tip of the cutter C, and its end is connected to the cutter C. It has reached the top.

Furthermore, as will be described later, the relationship between the conveyance chain 8 and the conveyance guide member 5 is such that there is a slight gap between the conveyance chain 8 and the conveyance guide member 5 when the first switching plate 4 is horizontal. shall be made.

11 is a cutter frame, and 12 is a dropper.

When cutting the culm S in this way, the first switching plate 4 is folded down and the second switching plate 6 is raised to guide the culm S conveyed by the culm transport chain 8 to the cutter C.

Then, it is cut by the mutually rotating disc blades 2, and falls downward to become organic fertilizer in the field.
As a result, the entire culm S is moved toward the two directions of the disk blade and is evenly cut.

In addition, when removing straw without cutting, the first switching plate 4
is raised to make it horizontal, and the second switching plate 6 is tilted to block the upper part of the cutter C, and the culm S transported by the transport chain 8 is transferred to the transport guide member of the first switching board 4. 5 and the smooth surface of the second switching plate 6.
It leads to 2.

In this case, the culm S is brought into pressure contact with the conveyance chain 8 by the conveyance guide member 5 of the first switching plate 4, and is forcibly conveyed along the arrangement angle of the conveyance chain 8.

In other words, the waste culm moves forward by a distance l where it is pressed against the conveyor chain 8 by the conveyance guide member 5, so during this straw removal work, the waste culm S is discharged toward one side of the combine harvester 9, and the next time the progress path is It does not become an obstacle.

Example ■ This example is described in the second claim; it is related to the invention, and its purpose is to overcome the first claim described in Example I.
and the switching operation mechanism of the second switching plates 4 and 6.

The common symbols are the same as those in Embodiment I, so redundant explanation will be omitted.

Therefore, in FIGS. 4 and 5, numeral 13 is a long first connecting metal fitting pivoted to the side plate 14 of the cutter frame 11, and 15 is a wire connected to one end of this first connecting metal fitting 13.

The other end of this wire 15 is connected to a switching lever 17 arranged near the driver's seat 16 of the combine harvester 9.

Reference numeral 18 denotes a first working rod which is pivoted slightly below the connection part 19 of the first connecting fitting 13 with the wire 15, and this first working rod 18 is further connected to the first connecting fitting 20 via the second connecting fitting 20. Although it is connected to the rotating shaft 21 of the switching plate 5, the connection between the second connecting fitting 20 and the rotating shaft 21 is fixed.

22 is a second working rod connected to the other end of the first connecting fitting 13, and the other end of this second working rod 22 is connected to the rotation shaft 24 of the second switching plate 6 via a third connecting fitting 23. Although it has been
It is fixed to the third connecting fitting 23 and the rotation shaft 24.

However, when cutting the culm S, the switching lever 17
, and move the wire 15 backward so as to push it out.

Then, the first connecting fitting 13 also rotates counterclockwise around the pivot portion, and the first operating rod 18 also moves rearward as being pulled by this.

The second connecting fitting 20 also rotates by approximately the same angle as the first connecting fitting 13, and the first switching plate 4 fixed thereto is inclined diagonally downward.

On the other hand, the second operating rod 22 is pulled together with the rotation of the first connecting fitting 13, which causes the third connecting fitting 23 to also rotate, and the second switching plate 66 is rotated by the rotating shaft 24 fixed thereto.
This will cause .

This results in the state at the time of cutting as described in Example (2).

When straw removal is to be performed without cutting, the switching lever 17 is set in the opposite direction to pull the wire 15 forward.

Then, contrary to the above, the first connecting fitting 13 rotates clockwise about the pivot portion, thereby drawing the first operating rod 18 forward.

As a result, the second connecting fitting 20 also connects to the first connecting fitting 1.
