BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mowing machine capable of simultaneously cutting grass on an upper surface such as a ridge and a slope.

[0002]

2. Description of the Related Art
This type of grass mower includes a horizontal rotary mowing body that cuts a horizontal plane, and an inclined rotary mowing body that is positioned beside the horizontal rotary mowing body and that cuts an inclined surface. Some can cut grass on the slope at the same time. However, conventionally, if the rotation direction of the rotary mowing body is not considered at all, there is a disadvantage that the cut grass is scattered toward the field, and it is necessary to treat the grass dropped on the field after cutting. Atsuta. Therefore, by setting the rotation direction of the horizontal rotary mowing body and the inclined rotary mowing body to the direction in which the front end of each rotary mowing body rotates toward the gap between both rotary mowing bodies, the mowing grass is reduced. It is conceivable to scrape between the two rotating cutting bodies without scattering them toward the field, but because the harvested grass cannot be actively scraped up to the upper surface of the ridge even if the rotation direction is simply considered. However, there is a disadvantage that the cut grass is still positioned on the slope and eventually falls to the field.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a mower, which is connected to the front end of a traveling machine body 2 via a connecting arm 3 so as to be vertically swingable, and has an arbitrary height by an adjusting arm 4. It is to be fixed to.

Reference numeral 5 denotes a gear case fixed to the tip of the connecting arm 3. One end of an input shaft 6 rotatably supported in the gear case 5 in the left-right direction is provided with an output on the engine 7 side. An input pulley 10 is provided which is linked to the pulley 8 via a transmission belt 9.

Reference numeral 11 denotes a first cutting blade shaft rotatably supported by the gear case 5 in a vertical direction, and the first cutting blade shaft 11 has a driven bevel gear 12 provided at an upper end thereof. Driven by being engaged with a drive bevel gear 13 provided on the input shaft 6, a horizontal rotating blade 14 is provided at a lower end protruding from the lower surface of the gear case 5 along a horizontal plane.

On the other hand, reference numeral 15 denotes an upper cover for covering the upper part of the horizontal rotary cutting blade 14. The upper cover 15 is provided on a top surface of the gear case via a pair of front and rear upper brackets 16 fixed to the left and right. 5, the left end of the upper cover 15 in the left-right direction has a long hole 17 a facing the left-right direction.
The extension cover 17 is attached via a bolt 18 inserted through the extension cover 17.

Reference numeral 19 denotes a side cover which is provided on the outer edge of the extension cover 17 via a hinge 20 so as to be swingable up and down. The outer surface of the side cover 19 has a vertical direction. A pair of front and rear side brackets 21 are fixedly provided, and a base plate 22 is provided between the two side brackets 21 so as to be vertically adjustable. The base plate 22 includes the first cutting blade shaft. A second cutting blade shaft 23 that is deviated rearwardly by a predetermined length L with respect to the front / rear position of 11 is rotatably supported, and the second cutting blade shaft 23 that protrudes inward of the side cover 19. An inclined rotary blade 24 is provided at the tip.

The inclined rotary cutting blade 24 is driven at the same time as the horizontal rotary cutting blade 14 by connecting a base end thereof to a flexible transmission shaft 25 connected to the input shaft 6, and The rotation direction of the horizontal rotary cutting blade 14 and the inclined rotary cutting blade 24 is determined according to the rotation of the rotary cutting blades 14 and 24.
The front ends of the rotary cutting blades 14 and 24 are set in the directions of rotating toward the gap between the rotary cutting blades 14 and 24, respectively. The peripheral speed of the cutting blade 14 is set higher than the peripheral speed.
That is, by making the number of teeth of the driving bevel gear 13 smaller than the number of teeth of the driven bevel gear 12, the inclined rotating blade 24 is rotated at a high speed with respect to the horizontal rotating blade 14, thereby cutting the inclined rotating blade 24. The object and the cut material of the horizontal rotary cutting blade 14 scattered toward the inclined rotary cutting blade 24 can be vigorously scraped up from the slope to the horizontal plane.

On the other hand, reference numeral 26 denotes a guide plate, and the base end of the guide plate 26 has a long hole 2 extending in the left-right direction.
6a is fixed to the upper bracket 16 via a bolt 27 inserted through the guide plate 2a.
A long hole 26b facing in the front-rear direction on the 6 side, and a side bracket 2
It is fixed to the upper end of the side bracket 21 via a bolt 28 inserted into the long hole 21a facing the one side in the vertical direction. That is, when the bolt 28 is loosened, the long hole 21a
And 26b, the swing angle of the side cover 19, that is, the inclination angle of the inclined rotary blade 24, can be adjusted. On the other hand, when the bolts 18 and 27 are loosened, the guide action of the long holes 17a and 26a is achieved. The right and left positions of the side cover 19, that is, the right and left positions of the inclined rotary cutting blade 24 can be adjusted by the above operation. At the time of adjustment, the inclination angle is maintained at a predetermined angle. The rotary blades 14, 2 employed in the present embodiment
4 is a cord body 14 extending in the outer peripheral direction by centrifugal force.
The mowing is performed at a and 24a, but it goes without saying that the rotary mowing body of the present invention is not limited to this.

In the embodiment of the present invention constructed as described above, when the upper surface of the ridge is cut by the horizontal rotary cutting blade 14 and the slope of the ridge is cut by the inclined rotary cutting blade 24, each of the cuts is cut by both ends. The inclined rotating blades 24 are rotated at a higher speed than the horizontal rotating blades 24, and are scraped between the rotating blades 14 and 24. The cut material is scraped vigorously toward the rear of the horizontal rotary cutting blade 14, that is, toward the upper surface of the ridge.
Therefore, while the upper surface of the ridge and the slope are configured to be able to be cut at the same time, the cut grass is not allowed to fall into the field, but is scattered securely on the upper surface of the ridge without being left on the slope. As a result, it is not necessary to process a cut object that has fallen into a field after the cutting operation, and the working efficiency can be significantly improved.

In addition, since the inclined rotary cutting blade 24 is disposed so as to be deviated rearward with respect to the horizontal rotary cutting blade 14, the cuttings scattered by the horizontal rotary cutting blade 14 on the slope can be surely removed. As a result, the performance of preventing the cut product from falling into the field can be further improved.

The present invention is, of course, not limited to the above-described embodiment, and the point is that the peripheral speed of the inclined rotary cutting body is set to be higher than the peripheral speed of the horizontal rotary cutting body. Needless to say, it is sufficient that the peripheral speed can be increased by increasing the rotation diameter without increasing the angular speed of the inclined rotary cutting body. Further, since the speed difference between the two rotary cutting bodies is set relatively, it is also possible to provide a speed difference by, for example, reducing the rotation speed of the horizontal rotary cutting body, and in this case, Has the advantage that the cut of the cut material of the horizontal rotary cutting body can be reduced from scattering to the slope side.

[0015]

In summary, since the present invention is constructed as described above, a horizontal rotating reaper for cutting a horizontal plane and a sloping surface positioned on the side of the horizontal rotary reaper are cut. Although the upper surface and the slope of the ridge and the like can be cut at the same time by the provision of the inclined rotary cutting body, the cut material of both the rotary cutting bodies can be rotated by the rotation direction setting. While being squeezed between the bodies, the peripheral speed is set behind the centrifugal force of the inclined rotary reaper set to be higher than the horizontal rotary reaper, behind the horizontal rotary reaper,
That is, it scatters toward the upper surface of the ridge. Therefore, it is possible to make sure that the cut material is not scattered directly on the field, and that it is hardly left on the slope. As a result, it is not necessary to treat the cut material dropped on the field after the cutting operation. Thus, the working efficiency can be remarkably improved.
