Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a discharge guide device for culms cut by a combine cutter.

(Prior Art) A technique of discharging and guiding the culm cut by a disc cutter horizontally behind the combine with guides that can change the angle in the machine width direction is described in JP-A-53-44343. There is.

In this conventional technique, the technique of individually adjusting the plurality of guide plates requires complicated adjustment operations, and in the case of adjusting the plurality of guide plates in conjunction, the adjustment operation is simple. However, since the angle of each guide plate is changed in a parallel state, the discharge position in the machine width direction is changed, but the discharge width itself is not so changed.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned drawbacks of the prior art, and provides a discharge guide device for cutting culm that allows easy adjustment operation and also changes the discharge width of culm. Is what you are trying to do.

(Means for Solving the Problem) On a chassis 2 equipped with a traveling device 1, a threshing unit 4 is mounted with the culm outlet 3 facing backward in the traveling direction, and a plurality of disc blades 5, 5 are provided at the rear of the threshing unit 4. The disk cutter 6 composed of
Below the disc cutter 6, a plurality of guide plates 7 and 7 for guiding the cutting culm in the machine width direction are pivotally supported on pivot shafts 25 and 25 located above the cut land side (a). (EN) A cutting and drainage discharge guide device for a combine cutter, which is provided with an adjusting rod (28) whose angle can be changed by interlocking guide plates (7, 7).

(Operation of the device) The cut culms are supplied to the disc cutter 6 from the culm opening 3 of the threshing unit 4 located at the rear of the machine body, and a plurality of disc blades are provided.
It is shredded by 5, 5 and released downward.

When the shredded culm is discharged in a streak shape without being diffused for the purpose of subsequent baler work, etc., the plurality of guide plates 7 and 7 below the disk cutter 6 are left in a substantially vertical position. If so, the discharge is guided within the cutting width of the disc cutter 6.

In addition, when the cutting waste is returned to the field, if the adjusting rod 28 is operated and the plurality of guide plates 7 and 7 are interlocked, the pivot shafts 25 and 25 are rotated in the arrow (b) direction. Since the rotation fulcrum shafts 25, 25 of the guide plates 7, 7 are provided in the upper position on the side of the cut land (a), the angle of the guide plate 7 located on the side of the cut land (a) is adjusted to be larger. , Cutting culms are widely discharged toward the cut land side (a) and sprayed thinly on the field.

(Effect of the Invention) Since the present invention is configured as described above, a plurality of guide plates 7 below the disk cutter 6 are provided for cutting and discharging the culms.
Although it is possible to change the angle easily by interlocking 7,
The discharge width can be adjusted to be narrow or wide.

(Embodiment) In the illustrated example, a mowing and conveying section (not shown) in the front part is mounted on the traveling device 1, a threshing section 4 is mounted in the rear part, and a disc cutter 6 is mounted in the rear part of the threshing part 4. .

The threshing unit 6 is composed of a slinging chain 8, a handling drum 9, a swing sorting device 10 below the handling barrel 9, a grain trough 11 below the swing sorting device 10, an upper sorting dust chamber 12 and the like. The grain culm held and transferred by the slinging chain 8 is threshed by the handling barrel 9, and this threshing can be sorted by the lower swing sorting device 10. or,
The rear end of the rocking / sorting device 10 faces an opening 14 formed in the rear wall 13 of the threshing unit 6.

A cross-flow fan 15 is mounted on the upper portion of the sorting dust chamber 12 over the entire width of the threshing unit 4, and a dust outlet 16 is formed in the rear wall 13.

Reference numeral 17 denotes a culm transporting device, which is connected to the end of the loosening chain 8 and is capable of supplying the culm sent from the culm outlet 3 to the disc cutter 6.

The disc cutter 6 has a supply port 18 opened upward, is surrounded by a cutter case 19 that hangs downward, and has rotating shafts 20 and 21 that are hung between both side plates of the cutter case 19 and a rotation on the upper front side. Sweeping bodies 22, 2 attached to the shaft 20 at predetermined intervals
2 and disk blades 5, 5 and the like, which are attached to the rotating shaft 21 on the lower rear side at predetermined intervals. 23 is a guide rod for culmination.

Further, the cutting waste discharge position of the disc cutter 6 is located in the dust wind passage from the dust discharge port 16 of the transverse fan 15.
Further, the opening 14 for discharging the straw waste or the like sent out from the rocking / sorting device 10 is located below them.

In addition, the lower part of the cutter case 19 expands rearward,
A plurality of guide plates 7, 7 are disposed inside the expansion portion back plate 24 so as to project into the cutter case 19.

The guide plate 7 is configured so that the angle can be changed in the machine width direction, and its rotation fulcrum shaft 25 is provided at a position higher than the cut land (a) of the machine body.

Further, pins 26, 26 are attached to the upper back portions of the respective guide plates 7, 7, and the pins 26 are projected rearward from the long holes 27 of the back plate 24,
Furthermore, the rear end of the pin 26 is movable in the width direction of the machine body.
It is fitted in a long hole 29 drilled in.

The threshed culm is taken over by the culm carrier device 17 and conveyed in a state of being laid sideways with its tip end side facing the abandoned side a, and the supply port 18
Is supplied to the cutter case 19 from the
It is shredded to a predetermined size between 2,22 and the disk blades 5,5 and dropped and discharged.

If you want to discharge the fall culms that have been dropped and discharged in a streak shape without spreading due to subsequent baler work etc., set the guide plates 7, 7 to the first position.
As shown in the figure, when placed in the drooping state, the cut culm falls and is discharged in a relatively narrow width.

Next, when the cut culms are returned to the field, it is necessary to discharge them widely and thinly to accelerate their deterioration.

In this case, when the adjusting plate 28 is moved and adjusted in the opposite (a) direction of the cut land, the pin 26 fitted into the long hole 29 of the adjusting plate 28 is adjusted.
Is also moved in the same direction, the guide plates 7, 7 are rotated in the direction of the arrow (b) about the rotation fulcrum shaft 25, and the inclination angle is adjusted as shown in FIG. At the time of this adjustment, since the rotation fulcrum shafts 25 of the guide plates 7 and 7 are provided in the upper position on the side of the cut land (a), the angle of the guide plate 7 located on the side of the cut land (a) is adjusted to be larger. Therefore, the cut culm can be widely sprayed toward the already-cut land side (a) and sprayed thinly. Although not shown, the adjusting rod 28 may be provided with an operating lever or the like so that it can be easily moved and adjusted.
