である。(d) Means for Solving the Problems Therefore, in order to achieve the above object, the present invention has been developed by mounting parallel shafts with the high-speed rotating shaft at the rear and the low-speed rotating shaft at the front. A straw cutter for a combine harvester is constructed by fitting disc blades at predetermined intervals into the straw cutter, and the lengthening plate of the plate body standing above the group of disc blades on the high-speed rotating shaft side is axially In the case where a large number of straightening plates are arranged side by side at intervals, the lower front side of the straightening plate has a concave notch cut out in an AC9 shape, and the upper front edge continuous to the concave notch has a along the straw supply path,
When viewed from the side, a space is formed between the upper circumferential edge of the disc blade group on the high-speed rotation shaft side and the concave notch, and the lower part of the concave notch intersects with this disc blade. That's what I did.

るのである。(E) Function With this structure, the waste straw that falls down the waste straw supply path falls along the front edge of the lengthening plate, and the disk blade group on the high-speed rotating shaft side and the disk blade group on the low-speed rotating shaft side are separated. It is fed between a group of disc blades and cut, but when this straw is cut, the part where the disc blade acts quickly is pulled quickly by the rotational force and feeding action during cutting. As the straw rotates during cutting, the delayed portion rises upwards, and as the straw rotates during cutting, the delayed portion rises backwards, and the resultant force causes the delayed portion to rise diagonally rearward and upward. The concave notch formed on the lengthening plate holds down the part of the straw that is about to be cut as it rises diagonally backward and upward, and the cut straw becomes the regular length and is cut downward. It is discharged.

The straw cutter is cut after it escapes, and overload on the straw cutter is avoided as much as possible.

に弾性体１４を介して連結して構成する。 Above the group of disk blades 3 on the side of the high-speed rotation shaft 1, there is a straightening plate 5 of a plate body, which is erected so that the plate surface is orthogonal to the axial direction of the high-speed rotation shaft 1. The lower part of the support plate 12 that supports each straightening plate 5 is connected to the high-speed rotating shaft 1.
There is a pivot 13 on the back of the cutter case E on the rear side of the
However, the upper part of the support plate 12 is connected to the upper part of the cutter case E via an elastic body 14.

Along with sloping it and aligning it with the straw supply path R,
When viewed from the side, a space P is formed between the upper circumference of the group of disk blades 3 on the side of the high-speed rotating shaft 1 and the concave notch 5a, and the lower part c of the concave notch 5a is located on this high-speed side. It is configured to intersect with the disc blade 3 of.

下方に排出される。 When this straw is cut, the disc blade 3,
The part where 4 acts quickly is pulled faster by the rotational force and feeding action during cutting, and the part that lags moves upwards, and the part that lags as the straw rotates during cutting rises backwards. Due to the resultant force, the part of the straw that is delayed as a whole will rise diagonally backward and upward, but the concave notch formed on the straightening plate 5 will remove the part of the straw that is going to rise diagonally backward and upward and be cut later. The cut straw is cut while being held down between point A and point B and from point B to lower part c, and the cut straw becomes the regular length and is discharged downward as shown by arrow B. .

極力回避されるようになる。 In addition, when the waste straw is supplied all at once from the waste straw supply path R, the excess waste straw is distributed between the upper circumference of the disc blade 3 on the high-speed rotating shaft 1 side and the concave notch portion 5a. After once escaping into the formed space P, the high-speed rotating shaft 1
The straw cutter is cut at a low rotation speed by the disk blade 3 on the side, and overload on the straw cutter is avoided as much as possible.

させることができるという効果がある。(G) Effects of the invention As explained above, the present invention has a high-speed rotating shaft on the rear side and a low-speed rotating shaft on the front side, and the shafts are mounted in parallel.
The straw cutter for a combine is constructed by fitting disc blades onto each rotating shaft at predetermined intervals, and the plate body is arranged vertically above the group of disc blades on the high-speed rotating shaft side. In a structure in which a large number of long plates are arranged side by side at intervals in the axial direction, the lower front side of the lengthening plate is cut out to form a concave notch, and the upper part connected to the concave notch is shaped. The front edge of the side is aligned with the straw supply path, and when viewed from the side, a space is formed between the upper circumference of the disc blade group on the high-speed rotating shaft side and the concave notch, and the concave Since the lower part of the missing edge is configured to intersect with this disc blade, when the straw is cut, the part where the disc blade acts quickly will be cut faster due to the rotational force and feeding action during cutting. The part that lags behind as it is pulled upwards, and as the straw rotates during cutting, the lag part rises backwards, and the resultant force causes the lag part to rise diagonally backwards and upwards. The concave edges formed on the lengthening plate hold down the part of the straw that is about to be cut as it rises diagonally backward and upward, and the cut straw is neatly cut to the correct length. Therefore, the use of the cut straw and the dropping of the cut straw after the fact can be carried out well. In addition, when the waste straw is supplied all at once from the waste straw supply path, the excess waste straw is removed from the space formed between the upper circumference of the disc blade on the high-speed rotating shaft side and the concave notch. The straw cutter is cut after it escapes once, which has the effect of avoiding overloading the straw cutter as much as possible.
