するものである。[Detailed Description of the Invention] This invention relates to a culm cutter for a combine harvester that can change the length of cut when cutting the culm that has been harvested and threshed by a combine harvester.

していた。 As a conventionally known type of culm cutter for combine harvesters, for example, Utility Model 55-54294
According to this, there were three or four rotating axes on which the disc blades were arranged.
The cutting dimensions are changed by rotating these shafts and changing their positions, which results in an extremely large size and high cost. In order to solve this problem, for example,
The device shown in Publication No. 56-136542 was also developed, but although it did have two rotating shafts and did not increase in size, the operation to change the cutting dimension was only possible with one rotating shaft. Since this is done by sliding the shaft laterally, the mechanism is complicated and the switching operation is not smooth.

たものである。 Therefore, the idea was to arrange a high-speed rotation shaft and a low-speed rotation shaft in parallel inside the cutter case, and connect one of the two rotation shafts through a long hole drilled in the side plate of the cutter case. In addition to being able to change the distance between the two rotating shafts,
Both rotating shafts each have disc blades with multiple diameters,
By arranging pieces of the same diameter to face each other and moving the two rotating shafts closer or further apart, the combination of opposing disc blades can be changed, thereby changing the cutting dimension of the culm. It was developed for the purpose of providing a culm cutter for combine harvesters that can be changed.

参照）。 Next, an embodiment of the culm cutter for a combine harvester according to this invention will be described based on the drawings. 1 is a low-speed rotating shaft disposed inside the cutter case 2, and 3 is parallel to the low-speed rotating shaft 1. This is a high-speed rotating shaft located at the Reference numeral 4 denotes a long hole drilled in both side plates of the cutter case 2, and the long hole 4 forms an arc centered on the rotating shaft 5, and is oriented toward the high-speed rotating shaft 3. . The end of the low-speed rotating shaft 1 is slidably engaged with the elongated hole 4. 6 is an arm connecting this low-speed rotating shaft 1 and the rotating shaft 5, and 7 is another rotating shaft. And gears 1', 3',
5' and 7' are arranged, and these are meshed in series. 8, 9 and 8', 9' are disc blades arranged on the low-speed rotating shaft 1 and high-speed rotating shaft 3, of which 8, 8' are large-diameter disc blades, and 9, 9' are small-diameter disc blades. Use a disc blade. 8 and 9 are arranged alternately with respect to the low-speed rotating shaft 1, and 8' and 9' are arranged alternately with respect to the high-speed rotating shaft 3, so that those with the same diameter face each other. Set it in the desired position. In other words, the large-diameter disk blade 8 of the low-speed rotating shaft 1 and the large-diameter disk blade 8' of the high-speed rotating shaft 3 are arranged as a pair.
The small diameter disc blade 9 of the low speed rotating shaft 1 and the small diameter disc blade 9' of the high speed rotating shaft 3 form a pair. Although the above-mentioned disc blades are described using two types, large and small, they are not limited to two types, and include large, medium, small,
Theoretically, it does not matter how many types there are (see Figure 8).

のである。 Therefore, the low speed rotating shaft 1 is connected to the cutter case 2.
In the elongated hole 4 provided in the side plate of , it is assumed to be moved to a position farther away than the high-speed rotating shaft 3, that is, to the left in the drawing. In this case, the distance between the rotating shafts 1 and 3 becomes wider, but at this stage, the large-diameter disk blades 8 and 8' partially overlap, and the small-diameter disk blades 9 and 9' overlap. Since they are separated from each other and there are no overlapping parts, in the end, the large diameter disk blade 8,
Cutting work will be done only at 8'. Since the large and small disk blades 8, 8', 9, and 9' are arranged alternately with respect to each rotating shaft 1, 3, in the above case, the large diameter disk blade 8 on each rotating shaft 1, 3 ,8'
The culm will be cut at intervals of .

せしめればよいのである。 Next, when the low-speed rotary shaft 1 is moved to the high-speed rotary shaft 3 side within the elongated hole 4, the small-diameter disc blades 9 and 9' also overlap, and the cutting is performed by all the disc blades. It turns out. In this case, the cutting interval becomes shorter. In addition, when the diameter of the disc blade is made into three types as shown in FIG. 8, it is sufficient to stop the low-speed rotary shaft 1 in the elongated hole 4 at an approximately intermediate position.
