Description

[Detailed Description of the Invention] The present invention relates to a cutting device for a threshing machine used in a combine harvester, such as when cutting pillows.

Conventionally, cutting work on combine threshing machines was done by opening the guide rail at the end of the lifting conveyor chain and attaching a guide rail for cutting corners, which was very troublesome. Moreover, the supply of grain culm was not smooth.

Therefore, a device has been proposed in which the tip of the guide rail is lifted by hand and held in that position with a set pin, thereby facilitating the cutting work.

However, even with this device, when moving from cutting work to normal combine harvester work, it is often the case that the user forgets to remove the set pin and continues to work with the combine harvester in a careless state. When I discovered the erroneous operation in a pool of grain culm in the machine feeding section, I had to get out of the driver's seat, go into the erect culm, and return to normal combine harvester operation.

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a device for cutting corners in a threshing machine for a combine harvester, which eliminates the above-mentioned drawbacks by arranging a structure in which the end joint of the guide rail can be operated from the driver's seat. be.

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

As shown in Fig. 1, the combine 1 has a reaping section 2 disposed at the front of the machine, a threshing machine 3 mounted on the rear side, and a driver's seat 5 on the other side. On the other side, a paddy receiving section 6 is provided.

As shown in FIGS. 2 to 4, the threshing machine 3 has a feed chain 7 located on the side of the machine body, and the feed chain 7 is fed from the reaping section 2 via a lifting conveyance chain. The shell culm 9 is conveyed rearward while being held between a guide rail 10 and threshed in cooperation with a handling cylinder 11.

The guide rail 10 has many nodes 10a, 10b...
A rod 14 that is slidably guided by the frame 13 is fixed to the fulcrum pin 12 of each node, and the rod 14 is fixed between the guide rail 10 and the frame 13. A spring is contracted to surround the .

Therefore, the guide rail 10 is configured to be bendable and is pressed against the feed chain 7 with an appropriate force.

Further, the distal end section 10a of the guide rail 10 has a guide plate 15 whose distal end is notched upward and extends obliquely upward, and the pin 1 is disposed in the middle of the guide plate 15.
6 and a long hole 17, a rod 18 is pivotally attached.

The rod 18 is slidably guided by the frame 13, and a portion of the rod protrudes above the frame 13. An end cam 19 is provided on the protruding portion of the rod so as to abut against the frame 13.
is rotatably fitted in the rod, and a driven end cam 2o that matches the cam 19 is fitted with a pin 21 at the upper end of the rod.
Fixed by

An arm 19a is fixed to the end cam 19, and one end of a connecting lever 22 is pivotally supported on the arm 19a.

As shown in FIG. 1, the connecting lever 22 extends to the driver's seat 5, and a grip 22a is fixed to the other end of the driver's seat, and the grip can be moved to two positions, namely, a pulled position and a returned position. It is constructed to maintain stability.

In addition, the guide rail tip section 1 is arranged so as to surround the rod 18.
A spring 23 is compressed between Oa and the frame 13, and constantly urges the rod 18 downward together with the tip section 10a.

In addition, in the figure, 25 is a raised husk culm, 26 is a side cover of the threshing machine 3, and 27 is a top cover.

Since the present invention has the above configuration, the grip 22a can be held in the return position during normal combine harvester work, and
The tip section 10a of the guide rail 10 is kept in a state as shown by the chain line in FIG.

In this state, the reaping section 2
The harvested grain culms are conveyed to a feed chain 7 and supplied to a threshing machine 3.

If you are using the threshing machine 3 of the combine harvester 1 carelessly for cutting pillows, etc., stop the combine harvester 1 from running and
The operator pulls the grip 22a from the driver's seat 5 and releases the connecting lever 22.
The end cam 19 is rotated via the .

Then, the cam 19 works together with the driven end cam 20 to lift the rod 18, and as shown by the solid line in FIG.
and the tip section 10a of the guide rail 10 through the elongated hole 17.
The distal end of the feed chain 7 is tilted upward, and the supply distal end of the feed chain 7 is held in a wide open state.

Therefore, the operator gets off the driver's seat 5, goes to the threshing machine 3, and performs a shortcut operation by supplying the grain culms harvested by pillow cutting or the like through this large opening (7).

When the worker finishes the cut-off work and resumes normal combine harvester work, the operator returns to the driver's seat 5 and holds the grip 2 of the connecting lever 22.
After returning 2a to its original state and returning to the state shown by the chain line in FIG. 3, the combine 1 is run.

At this time, even if you forget to operate the grip 22a and a pool of grain culms occurs in the supply section of the thresher 3, you can immediately use the grip 22a in the driver's seat 5.
Just operate a.

As explained above, according to the present invention, even if you forget to lift and release the end section 10a of the guide rail 10 when moving from cutting work to normal combine harvester work, you can do it from the driver's seat 5, so you can do it from the driver's seat 5. There is no need to enter the shell culm 25, and the operation is very easy.

In addition, if you stop transporting grain culms for some reason, not just when you forget to perform an operation, and then suddenly restart the process,
A large amount of grain culm 9 is suddenly supplied to the feed chain 7, causing the grain culm to become clogged or rolling, but even in this case, the driver's seat 5 should be left in a careless state only when starting. If this happens, the supply to the feed chain 7 will be good, and
It is possible to prevent clogging of the grain culm, and further, even if the feed chain supply portion is likely to become clogged during normal combine harvester operation, it can be quickly cleared by operating from the driver's seat 5.
