FIG. 4 is a side view of the main part showing the tilling state by the rotary A work machine, and FIG. 4 is a side view of the main part showing the mowing state. In the figure, a rotary agricultural machine designated by reference numeral 1 is attached to the rear of an agricultural tractor via a three-point link hitch mechanism (not shown) so that it can be freely moved up and down, and a gear box 2 is installed in the center of the machine.
is provided. This gear box 2 has an input shaft 3
It is numbered so that it protrudes forward, and is connected to the PTO shaft of the tractor via a transmission shaft, a universal joint, etc., so that driving force is transmitted. An intermediate shaft 4 is provided parallel to the input shaft 3, and a small gear 5 and a large gear G are disposed at the rear ends of the intermediate shaft 4 and the input shaft 3 so as to be interchangeable with each other. A bevel gear 7 is fixed to the intermediate shaft 4, and a transmission shaft 9 to which a bevel gear 8 that meshes with the bevel gear 7 is fixed extends laterally from the gear box 2. This transmission @
9 extends into the chain case 10 provided at the side end of the fuselage via the transmission frame.
A chain 15 is stretched between the inner sprocket 11 and the sprocket 14 of the rotary shaft 13, which is mounted on the lower part of the support frame 12 attached to the opposite end of the chain case 10. The driving force is transmitted. The gear ratio between the small gear 5 and the large gear 6 is set to 1:4 or more. On the other hand, as shown in FIG. 2, the rotary shaft 13 has a claw attachment portion 1G fixed at a predetermined interval in the length direction, and the claw attachment portion 1θ is perpendicular to the rotary shaft 18. It has a rectangular shape that extends symmetrically in the direction of the arrow, and a claw 18 is attached to each outer end via a pivot pin or bolt 17.
It is pivotally supported so as to be swingable in the direction of rotation. In the mold 18, a horizontal blade part 18b is formed by bending the tip side from the vertical blade part 18a to one side in an L-shape, and a blade edge 18c is formed from the vertical blade part 18a to the horizontal blade part 181). ing. In addition, the pawl attachment portion 16 to which the mold 18 is attached is provided with a stopper that comes into contact with the side surface of the pawl 18 and restricts the rotation of the pawl 1B when the rake shaft 13 rotates at low speed in the direction of the arrow to perform tillage work. 19 is provided, and when the rotary shaft 13 rotates at high speed to perform mowing work, the pawl 18 is provided with a stopper 19.
It is rotated about the pivot bolt 11 and held in the radial direction by centrifugal force. Note that in the itt position where the pawl 18 is in contact with the stopper 19 that receives a reaction force in the rotational direction, a leaf spring (not shown) may be provided in order to eliminate lateral play of the pawl 18. Further, a q-tary F f'l equipped with the rotary shaft 13
``The industrial machine 1 has covers 2 suitable for work on the front and rear.
0.21 is installed. In the second embodiment of the present invention shown in FIG.
is attached to the intermediate shaft 4a, and the heavy vehicle 1 is attached to the end of the intermediate shaft 4a.
It meshes with 18a. Gears 22 and 23 are attached to the transmission shaft 9a.
is fixed, and the gear 23 has a gear 24 with a large reduction ratio,
Further, a speed increasing gear 25 is always meshed with the gear 23, and the gear 24 and the gear 25 are always rotatably attached to the intermediate shaft 4a. And the gear 24
Between the gear 25 and the gear 25, a sliding gear 26 that rotates integrally with a spline or the like is attached to the intermediate l1114a and is capable of one movement.A shift lever 21 installed protruding from the gear box 2a allows Rotational force is transmitted to the transmission shaft 9a. The above teeth ff123°25 and 22
．． The rotation ratio with respect to 24 is set to be 1:4 or more. Next, the operations of both of the above-mentioned embodiments will be explained. First, in the first embodiment shown in FIGS. 1 to 4,
When driving force is input to the input shaft 3 from the PTO shaft of the tractor, 1. When the intermediate shaft 5 is rotated by the gear 5.6 and the rotary shaft 13 is rotated in the forward direction, the pawl 18 comes into contact with the stopper 19 of the pawl attachment section 1G and rotation is restricted as shown in FIG. , it is possible to till the field in the same way as the well-known tiller. At this time, the rotary shaft 13 rotates at a predetermined number of revolutions (
For example, it is rotated by 2oor, p, m). Next, by interchanging the gears 5 and 6 and working as shown in Fig. 4, the pawl 18 rotates around the pivot bolt 11 and becomes free, and is held in place by centrifugal force. , weeds, etc. can be cut in the same way as a conventional flail blade. The rotational speed of the rotary shaft 13 at this time is 800 r, p, m or more. In addition, when performing tillage work by rotating the rotary shaft 13 at a low speed, if the sides of the pawl 18 are held between leaf springs while the pawl 18 is in contact with the stopper 19 of the pawl mounting portion 16, lateral play can be prevented. It can be suppressed. In the second embodiment shown in FIG. 5, by switching the shift lever 27, the rotary shaft 13
Shift to 2 gears, p9m and 800r, p, m or higher, and shift to 3rd gear.
Operations similar to those shown in FIGS. 43 and 4 can be performed. In addition to the above-described embodiments, the same operation can be performed by rotating the rotary shaft in forward and reverse directions, and the rotary shaft is not limited to the side drive but may also be a center drive.

At this time, the rotational position of the claws can be changed, so the same claw can be used for plowing and mowing, which makes it possible to do different tasks depending on the type of crop. IIY4 work can be performed, which improves the operating rate and is economical. In addition, since two types of work can be performed without replacing the claws or rake shaft, operability is good and work can be carried out efficiently.
