Description

[Detailed Description of the Invention] The present invention relates to a waste straw processing device for a combine harvester.

This invention shreds the threshed waste culm using a desk-type cutter or other type of cutter, and separates the root side and the tip side of the waste culm and collects them in a bag or partially collects them and releases the rest, while the root side is used as fertilizer. In addition, the tip side can be used separately for feeding.
Furthermore, the present invention aims to improve collection efficiency and waste culm processing efficiency by making it possible to collect waste culms without cutting them.

To explain the details of the embodiment with reference to the drawings, A is an automatic threshing device of the combine main body, and the culm that has been threshed and adjusted by the automatic threshing device A is provided at the rear of the combine main body by a conveying mechanism B. It is sent to a disc-type cutter C, where it is shredded.

The disc-type cutter C has a cutter mechanism part 3 consisting of a rotary blade 1 that rotates at low speed and has the function of feeding the culm, a rotary blade 2 that rotates at high speed and meshes with the rotary blade 1, and a cutter mechanism part 3 on the underside of this cutter mechanism part 3. A flip wheel (Peter) 4 provided, a lifting culm channel 6 having a downward discharge port 5 connected to the flip wheel 4, and a plurality of sections connected to an operating rod 7 on the lower side of the flip wheel 4. The cutter case 9 includes a cutter case 9 equipped with an opening/closing plate 8.

The above-mentioned flip-up wheel 4, lifting culm channel 6, and discharge port 5
is formed to have approximately the same length as the cutter mechanism 3, that is, to extend over approximately the entire length of the cutter case 9, and as is clear from FIG. It is divided into a plurality of parts, and a plurality of divided discharge ports 5' are formed.

Furthermore, the opening/closing plate 8 provided at the bottom of the cutter case 9, that is, the bottom side of the flip-up wheel 4, is divided into a plurality of parts, but the conditions such as the number of divisions and the width are determined by the divided discharge port 5'. It has been made compatible. In addition, each divided opening/closing plate 8 is connected to an operating rod 7, so that it can be fully opened or partially opened by the action of the operating rod 7. In some cases, the opening/closing plate 8 may be elastically mounted on the cutter case 9 so as to be opened and rotated downward.

Further, as is clear from the drawing, the conveyance mechanism B for the exhaust culm is constituted by a combination of a conveyor belt 11 and a guide rod 12, and a switching lever 13 is provided in the middle of this. are all introduced into the cutter C, and the culm is conveyed to the rear side of the cutter C in a virtual line state, and is collected by the culm collecting member 14. The two are mechanically connected so that when the switching lever 13 is set to the imaginary line position, the culm collecting member 14 rises from the imaginary line position to the solid line position.

Moreover, at one side opening end of each of the above-mentioned divided discharge ports 5',
The upper side of the square frame-shaped bag support frame 15 is pivotally supported.
A spring 16 is provided on the upper side of the bag support frame 15 to always urge the bag support frame 15 to rotate outward. Further, between the vertical rod portions on both sides of the bag support frame 15, a bag support frame 15 is provided.
A bag opening holding rod 17 that contacts the lower side is connected to the bridge so as to be able to rise and fall.The lower end of a connecting rod 18 is pivotally supported at the center of the bag opening holding rod 17, and the upper end of the connecting rod 18 supports the bag. It is connected to the middle part of a tightening lever 19 whose upper end is pivotally supported on the upper side of the frame 15.

And a mold locking rod 20 is installed inside the connecting rod 18.
is provided so that the side edge of the tightening lever 19 comes into contact with this, and this tightening lever 19
and the link 18 are designed to maintain a connection relationship that exceeds the deadline line.

Further, the upper side of an upwardly U-shaped bag support frame 21 is fixed to the other opening end of the divided discharge port 5', and the lower side of the bag support frame 21 is bent outwardly.
A bag locking portion 22 bent into a letter shape is formed.

Reference numeral 23 denotes a bag opening holding rod that fits into the lower side of the bag support frame 21 from the outside, and this and both vertical rods of the bag support frame 21 are connected by a connecting rod 24.
A spring 25 is elastically installed between the bag opening holding rod 23 and the vertical rod part 4, and is configured to constantly press the bag opening holding rod 23 against the lower side of the bag support frame 21. In the figure, 26 is a bag for storing shredded culms.

D is a bag receiving member provided at the lower part of the rear wall of the combine main body so that it can be folded and stored. This bag receiving member D includes an L-shaped board 27 fixed to the combine main body, a connecting rod 28 with one end pivotally supported on both sides of the board 27, and a bag receiving frame pivotally supported on the other end of the connecting rod 28. 29, and by folding the bag receiving frame 29 and the connecting rod 28 in the direction of the arrow in FIG. 2, this member can be folded and stored as shown by the imaginary line. be.

The bag receiving frame 29 is connected to the connecting rod 28 and the bag receiving frame 29 in order to rotate downward and leave the bag together in the field when the shredded culms in the bag 26 exceed a set weight.
A spring 30 is provided between the two. In this case, the receiving plate 31 shown in FIG. 2 becomes unnecessary.

Since the present invention is configured as described above, the threshed culm can be shredded with a desk-type cutter and left in the field as it is, and the shredded culm can be cut into pieces, for example, the root of the culm. You can separate the side and tip sides and collect them in bags.

Therefore, the root side can be recovered as fertilizer and the tip side can be recovered as feed, making effective use of the culm. In addition, it is possible to collect only the root side or tip side of the desired culm and leave the rest in the field without installing bags at all of the divided discharge ports.Furthermore, by using a beater, it is possible to It has the advantage that there is no wind force inside the bag because it flips up the shredded culm without causing any damage.

In addition, in the present invention, the uncut culm can be passed above the cutter and collected into the culm by the switching means without being fed into the cutter mechanism. The practical effects are great, such as the collection of chopped culms, collection of uncut culms, and the ability to appropriately process, recover, and release culms for a variety of purposes.
