Description

[Detailed description of the invention] This invention relates to a straw guide device for a disc cutter that cuts straw discharged from a threshing machine along the culm direction, The purpose of the present invention is to realize a device that facilitates the operation of a guide plate that guides the straw and covers the discharge port of a disk cutter, and that not only has a guiding function for the cut straw but also has a high level of safety.

Since the discharge port of the disc cutter is longer than the culm of the waste straw, the guide plate covering the discharge port must also be longer.

If the elongated guide plate were pivoted at the side ends, it would be difficult to lift it up and it would be difficult to operate smoothly, and if it was pivoted at the center side, the side ends would open during lifting, which would be dangerous.

This invention is intended to eliminate such inconveniences and is constructed as follows.

That is, a disk cutter 4 for cutting the waste straw along the culm direction is provided at the straw removal position of the threshing machine 3 mounted on the chassis 2 equipped with the traveling device 1, and from the discharge port of this disk cutter 4, The main guide plate 7 can be switched freely between a guiding state in which the cut straw to be discharged is guided toward the center of the chassis 2 and a lifting state that covers the discharge port.
is pivotally mounted inward from the side edge, and an auxiliary guide plate 6 is provided at the side edge position of the main guide plate 7 to assist in guiding the cut straw so as to cover the discharge port when the main guide plate 7 is in the lifted state. This is a straw removal guide device for a cutter.

By configuring this invention as described above, the invention has the following technical effects.

That is, since the long main guide plate 7 is pivoted inward from the side end, that is, closer to the center of gravity, the disc cutter 4
When lifting the main guide plate 7 to cover the discharge port of the disc cutter, it can be done with a light force, and when the main guide plate 7 is lifted, the auxiliary guide plate 6 covers the opening at the side end. It is possible to completely cover the outlet of No. 4 to improve safety.

Next, an embodiment of this invention will be described with reference to the drawings.

1 is a crawler, 12 is a chassis, and 3 is a threshing machine.

The disc cutter 4 has disc blades arranged at appropriate intervals on a rotary shaft 5 that is mounted approximately parallel to the culm of the straw to be discharged to the straw discharging position of the thresher 3. The structure is such that the straw is shredded between the rotor and the rotor facing each other.

The auxiliary guide plate 6 is provided on the side of the lower cutting straw falling opening of the disc cutter 4, and is composed of a side plate and a rear plate, and prevents the cut pieces from falling to the side of the chassis 2. It is fixed to the machine frame so that hands cannot be inserted inside.

The main guide plate 7 covers the auxiliary guide plate 6 to form a gutter shape,
It is pivoted at a portion located inside the side plate and is tensioned by a spring 8.

The main guide plate 7 is configured such that it escapes upward when the tip collides with a ridge or the like under the action of a spring 8 in the vertical direction, and can be stored at the top position when not in use.

When the chassis 2 driving the crawler 1 moves forward, the straw cut by the disk cutter 4 is guided by the auxiliary guide plate 6 and the main guide plate 7 and scattered over the field.

During such work, when the main guide plate 7 collides with an obstacle, it escapes upwards, thereby preventing damage.

The auxiliary guide plate 6 maintains the closed state without causing the cut piece to fall to the side of the fuselage even if the leading end of the main guide plate 7 moves upward using the pivot point as a fulcrum.

In particular, when the main guide plate 7 is stored at the top, the auxiliary guide plate 6 prevents the hand from being inserted from the side, resulting in an extremely safe device.

As described above, since the pivot portion of the main guide plate 7 is provided inside the side end, the upward movement by the spring 8 is light and smooth as in the embodiment, and the main guide plate 7 is connected to the discharge port of the disc cutter 4. When stored in a state where it is covered, the auxiliary guide plate 6 covers the discharge port and is safe.
