Description

[Detailed description of the invention] This invention uses a rear switching cover to form an exhaust culm at the top of the cutter case when switching between cutting and discharging the threshed culm and discharging it as a long culm without cutting it. Relating to a waste culm processing switching device that allows the culm inlet to be opened and closed, and when cutting, the waste culm falls horizontally from the inlet into the cutter case, and that the operation can be performed from the operator's seat of the combine harvester. It is something.

Conventionally, there is a device that switches the culm between cutting and non-cutting, but when cutting the culm, if the culm does not fall horizontally into the cutter case, the cutting will not be done evenly. There is a problem that it cannot be done.

However, when guiding the culm coming out of the combine harvester's culm in one direction to the cutter, the inlet side of the input port may not be parallel due to the angle of the conveyor chain, the difference in poly 1 neem on the stock side and the tip side of the culm, etc. If so, the stock side will fall into the cutter case first.

Therefore, this idea was developed by forming an exhaust culm inlet just above the cutting part of the cutter stored in a cutter case installed at the rear of the combine, and tilting the inlet side of the exhaust culm input so that the tip side is closer to the combine. At the same time, a guide rail is arranged in parallel on the upper surface of the side plate of the cutter case along this discharge culm input port, and a rear switching cover is provided that is bendable to the guide rail and can reach the opening/closing plate of the upper cover. is fitted in a sliding manner, and one end of the working rod is connected to the rear end of the rear switching cover, and the other end of the working rod is fixed to one end of the connecting fitting pivoted to the side of the upper cover, Moreover, the other end of this connecting fitting is connected via a wire to a switching bundle near the driver's seat of the combine, and the connecting fitting is rotated around a pivot point by pulling or pushing out the wire, and this connecting fitting is Since the operating rod fixed to the metal fitting cannot be rotated, the rear switching cover is slid within the guide rail to open and close the culm input port, and the culm is fed into and out of the cutter case. When dropping the culm into the cutter, the culm falls horizontally to ensure cutting, and this function can be performed while remaining in the operator's seat of the combine. It was developed for the purpose of providing a device.

Now, to describe an embodiment of the exhaust culm processing switching device according to this invention with reference to the drawings, 1 is a cutter case disposed behind the culm exhaust port of the combine harvester, and a desired material is placed inside this cutter case 1. A culm cutter C is stored.

This culm cutter C is, for example, as shown in the figure.
Two parallel rotating shafts 2 with different rotational speeds are arranged so as to be perpendicular to the direction of movement of the culm, and a disk blade 3 and a feed rotary 4 are arranged on both rotating shafts 2 at regular intervals. It is composed.

Reference numeral 5 denotes a culm input port formed in the upper part of the cutter case 1, and the inlet side 9 of this culm input port 5 is formed so as to be aligned with the rotating shaft 2 as shown.

That is, this culm input port 5 is connected to the cutter case 1.
It is formed directly above the cutting part of the culm cutter 〇 stored inside the culm, and the culm cutter C is cut so that the root side and the tip side of the culm, which are pinched and conveyed by the culm conveyance chain 22 (described later), fall into the cutter C at the same time. The stem is formed so that the upper opening on the base side is located at the rear compared to the entrance on the tip side.

Reference numeral 6 indicates a U-shaped guide rail arranged parallel to the upper surface of both side plates 7 of the cutter case, and reference numeral 8 indicates a rear switching cover arranged so as to be slidably fitted onto the guide rail 6.

This rear switching cover 8 can reach the opening/closing plate 19 of the upper cover 11, which will be described later, and is formed so that it can be bent in the middle, so that it can be sealed when sliding it to close the discharge culm input port 5. In order to do this, its tip is shaped to match the shape of the end 9' of the culm input port 5 closer to the combine harvester.

9 is the inlet side of the culm input port 5.

Reference numeral 10 denotes a connecting metal fitting pivotally attached to the side of the upper cover 11 of the conveying section, one end of which is fixed to one end of the working rod 12, and a wire 13 is connected to the other end.

The other end of the operating rod 12 is pivotally connected to the rear end of the rear switching cover 8, and the other end of the wire 13 is connected to a switching bundle located near the driver's seat of the combine harvester. .

Reference numeral 14 indicates the end of the connecting fitting 10 on the side of the working rod 12 and the upper cover 1.
This is a spring that connects the first side to the combine harvester side, and is configured to be stretched when the wire 13 is pulled.

In the drawing, reference numeral 15 denotes a tip guide plate that is openable and closable on the tip side above the cutter case 1, and a guide piece 17 having a long hole 16 is fixed on the outside of this guide plate 15. A guide rod 18 that slides within the elongated hole 16 is disposed at the end of the connecting fitting 10 on the side of the working rod 12.

Further, 19 is an opening/closing plate rotatably arranged behind the upper cover 11, 20 is a cutting straw discharge port at the bottom of the cutter case 1;
21 is a dropper, and 22 is a culm conveying chain.

Next, the operation of the culm treatment switching device according to this invention will be described.

■ When cutting: In this case, pull the switching bundle near the driver's seat forward and pull the wire 13.

Then, the connecting fitting 10 rotates clockwise in the figure, and the operating rod 12 also rotates accordingly, and the rear switching cover 8 connected to this slides within the guide rail 6 and moves toward the rear of the cutter case 1. Then, as the guide rod 18 bends and reaches the opening/closing plate 19 of the upper cover 11, the guide rod 18 also slides within the elongated hole 16 of the guide piece 17 to close the tip guide plate 15.

The movement of the action rod 12 opens the culm input port 5 of the cutter case 1, and the culm guided by the culm conveying chain 22 reaches the inside of the cutter case 1, that is, the culm cutter C, and is cut. It will be done.

Here, since the artificial side 9' of the culm input port 5 is formed to match the movement of the culm, the culm falls exactly horizontally into the cutter case 1.

This is due to the following reason. In other words, when threshing is performed using a combine harvester, the head side moves forward while being held by the conveyor chain, but the head side receives the threshing action from the threshing barrel, which creates resistance and does not necessarily allow for smooth forward movement.

In other words, there is a tendency to lag behind the stock end, and even with this delay, when cutter C falls, both the stock end and the tip, in other words, the entire culm, must fall at the same time to cut evenly. In order to avoid this, the above-mentioned configuration was adopted.

The cut straw then falls into the field from the cut straw outlet 20 at the bottom of the cutter case 1.

II. Case of non-cutting In this case, the wire 13 is pushed out by tilting the switching bundle near the driver's seat in the opposite direction.

Then, the traction force of the spring 14 is also added, and the connecting fitting 10
rotates counterclockwise, and the rear switching cover 8 slides within the guide rail 6 and closes the culm input port of the cutter case 1.

For this purpose, the lower part of the opening/closing plate 19 of the upper cover 11 is opened, and the rotation of the operating rod 12 causes the guide rod 18 to slide within the elongated hole 16 of the guide piece 17 to open the tip guide plate 15. The culm conveyed by the culm conveying chain 22 slides on the upper surface of the rear switching cover 8 and falls onto the dropper 21.

When a certain amount is reached, it will fall onto the field.

The opening/closing plate 19 is used to open the opening/closing plate 19 and dispose of the clogged culm in the upper cover 11.

As described above, according to the culm processing switching device according to this invention, when switching between cutting and non-cutting, the culm inlet of the cutter case is reliably opened and closed, and the path for the culm to move is also securely opened and closed. As a result, the culm will not be accidentally cut when not being cut, and when cutting, the culm will fall horizontally into the cutter case and be cut reliably, and the operation can be done remotely from the driver's seat. Its effects are extremely large, such as being able to be manipulated.
