Description

[Detailed Description of the Invention] This invention relates to a combine harvester equipped with a dropper that can slide left and right.

In conventional combine harvesters, the dropper for discharging the threshed waste culm was fixed directly behind the combine's waste culm transfer device, so the waste culm was necessarily discharged directly behind the combine.

However, when the harvesting and threshing in one run of the combine in the field is completed and the next run is about to start harvesting and threshing, the waste culm discharged directly behind the combine is lying in the path of the combine. As a result, not only does it impede the combine's smooth running, but the culm gets trampled by the combine and gets dirty with mud, making it impossible to use the culm. There were drawbacks.

This invention was made to solve the above-mentioned drawbacks.

This invention will be explained below based on embodiments shown in the drawings.

The dropper force bar 25 has a front opening 28 and a lower opening 29, and the front opening 28 is connected to the rear opening 3 of the culm cover 2.

Further, as clearly shown in FIG.
The left end of the culm 7 is sloped downward, absorbing the thickness of the stock base which is thicker than the tip of the culm, and allowing the culm to be placed on the culm holder 27 as horizontally as possible. It is done like this.

The discharge culm holder 27 faces the lower opening 29 of the dropper cover 25 in the normal state due to the spring 30, and on the other hand, when the discharge culm is discharged, that is, when a predetermined amount of the discharge culm is placed on the holder 27, the discharge culm bundle is The spring 30 expands under the force of gravity and moves downward.

A pair of culm support rods 31, 31 are attached to the lower edge of the rear wall of the dropper cover 25 in a hanging manner.
The lower ends of 1 and 31 extend below the pedestal 27.

On the left side of the pedestal 27 (see Figure 2), there is a vertical plate 32 that aligns the roots of the culms. It is fixed to the top cover 25 and the movable rail 20.20.

A dropper cover support arm 33 having a U-shaped cross section and whose tip extends to the soil wall of the dropper cover 25 is fixed to the right side of the earthen wall of the culm cover 2.

The dropper cover 25 is also fixed by tightening the fixing bolt 34.

As shown in FIG. 4, a bracket 37 having an inverted L-shaped cross section is fixed near the side opening 4 on the right side wall of the culm cover 2, and the earthen wall of the bracket 37 has a long length extending in the front and back direction. A hole 38 is formed, and a horizontal bar 39 is inserted into the long hole 38.
One bent end of the horizontal set 39 is fitted so as to be movable and rotatable, and the other bent end of the horizontal set 39 is fitted to the dropper cover 2.
It is detachably fitted loosely into a hole 40 made in the earthen wall of No. 5.

The horizontal bar 39 has a side opening 4 of the culm cover 2.
A side protection plate 41 large enough to cover the combine harvester 1 is attached in a hanging manner, and the side protection plate 41 moves toward and away from the combine 1 as the dropper 23 slides left and right. There is.

In addition, near the upper edge of the side opening 4c75 of the culm cover 2,
The upper edge of an upper protection plate 42 as shown in FIG. On the other hand, when the dropper 23 protrudes to the right with respect to the combine 1, the dropper
23, the culm cover 2, and the side protection plate 41, and it also touches the upper edge of the dropper cover 25 or the side protection plate 41 and naturally moves according to their movement. It is made to be pushed upward.

Next, a method of using the apparatus of the above embodiment will be explained.

The culm cutting device 10 is attached to the combine 1, and the dropper 23 is moved and fixed to the left side until going to the field so that the dropper 23 does not get in the way of running on the road.

After arriving at the field, the dropper 23 is fixed to the combine 1 so as to protrude to the right.

Then, in conjunction with the above operation, the side protection plate 41 naturally moves away from the combine harvester 1, and at the same time, the upper protection plate 42 moves upward and becomes approximately horizontal.

Therefore, by the function of both the protection plates 41 and 42, it is possible to prevent the operator from getting caught in the culm cutting device 10, the culm transfer device 5, etc.

In such a state, if the culm transfer direction switching lever 9 is turned downward and the field is driven, the culm that has been reaped and threshed will be sent out via the lever 9 and the culm transfer device 5 onto the receiving table 27. When a predetermined amount of the waste culm is accumulated on the pedestal 27, the spring 30 is expanded by the weight of the waste culm, and the waste culm is discharged into the field in a predetermined amount.

By the way, since the dropper 23 protrudes to the right with respect to the combine harvester 1, there is also a side opening 4 in the culm cover 2.
Compared to conventional combine harvesters,
The culm is discharged to the right.

Therefore, even if the combine harvester 1 completes its run and is run for reaping or threshing in the next run,
The combine 1 does not step on the culm, can run smoothly, and does not stain the culm with mud.

On the other hand, when cutting and discharging the culm, dropper 2
3 is returned to its original position and drained at that position, and at the same time, the free end of the culm transfer direction switching lever 9 is raised.

Then, the culm enters the cover 11 through the input port 15 of the culm cutting device 10, is cut by the culm cutting blade 13, and is cut by the culm cutting blade 13.
It is discharged from the discharge port 14.

In addition, if the culm cutting blade 13 or the like breaks down or becomes worn out, the rear wall upper part 11a of the cover 11 can be easily removed by removing the screws 17 securing it, and then cut through the rear opening 18. The culm cutting blade 13 and the like can be easily replaced and repaired.

In view of the above, according to this invention, the dropper is capable of sliding left and right with respect to the combine, and one of the left and right ends can protrude from the left side or the right side of the combine. Compared to conventional combine harvesters, the waste culm can be discharged to the left or to the stone part, so even if one run of the combine is completed and the combine is run for reaping or threshing in the next run,
The combine harvester 1 does not step on the culm, which eliminates the drawbacks mentioned above, and when the combine harvester is not running for reaping or threshing, the dropper can be retracted and placed within the width of the combine. Although it can be stored, the dropper does not get in the way.

Furthermore, the side protection plate and the top protection plate prevent the worker from getting caught in the culm cutting device, culm transfer device, etc. even when the dropper is protruded from the combine harvester. Therefore, even if the dropper is slidable from side to side, there is no danger and it is extremely safe.
