In order to achieve the above object, according to the present invention, in a [1-crie riding machine that can rotate forwardly and reversely, the rotation of the [l-crie shaft] reaches a high rotational speed suitable for tilling work when rotated in the forward direction. The pawl of the rotary shaft (the pawl with a cutting edge formed on the periphery of both the forward and reverse rotations through the d part) touches the flange of the rotary shaft at a position where a predetermined cutting angle is achieved during forward rotation. At the same time, the horizontal play is suppressed by root springs, etc., and when rotating in reverse, it is configured so that it can swing freely in the direction of rotation and is stopped in a fixed position by centrifugal force. Set a predetermined distance from the center line passing through the center of gravity of
2. When the pawl is rotated in the opposite direction, a predetermined cutting angle is formed between the back surface of the bent portion of the pawl and the normal line in the distal direction. [Function] Based on the above structure, according to the tillage and fine cutting device of the present invention,
It has a shape that combines both functions of mowing, and when performing tillage work by rotating the rotary shaft in the forward direction, the rotary shaft rotates at a low speed suitable for river plowing work, and the rotary shaft's decimal number “1” is the pivot point. When the supported claw rotates in the direction that receives the reaction force and is securely fixed by the stopper that maintains a predetermined cutting angle, when mowing the grass by rotating the rotary shaft in the opposite direction, [1- The chest shaft rotates at a high speed suitable for mowing, and the claw attachment is pivoted to the part, and the claw swings in the direction of rotation away from the stopper and is stopped at a fixed position by the centrifugal horn. Therefore, by selecting the rotary shaft to rotate forward or backward, the rotary shaft will rotate at a rotation speed suitable for tilling or mowing work, and the position of the claws will be set in the direction of rotation of the 0-crisp shaft. It is possible to perform the desired work smoothly and stably by automatically setting the settings. [Example] Hereinafter, an example according to the present invention will be described in detail based on the attached drawings. The figure is a schematic configuration diagram of the main parts showing the power transmission mechanism of the tilling and mowing device according to the present invention.
The rotary shaft shown in the figure is a side view of the 1 claw + j part, Figure 3 is a side view of the main part showing the 1:1 poop work by the rotary work machine of the present invention, and Figure 4 is a side view of the main part showing the same mowing work. Fig. 5 (f) and (b) are front views of the claw according to the present invention.
3 and a side view, and Fig. 6 is a side view showing a conventional mowing circular upper claw. It is mounted so that it can be lowered freely via a link hitch mechanism, and a gear box 2 is installed in the center of the fuselage. This gear box 2 is provided with an input shaft 3 protruding forward,
It is connected to the PTO shaft of the tractor via a transmission shaft, a universal joint 1, etc., and is designed to transmit driving force. , E A bevel gear 4 is attached to the tip of the blade shaft 3, and meshes with a bevel gear 6 attached to the end of the intermediate shaft 5. A gear 7.8 is fixed to the intermediate shaft 5, the tooth width 7 has a normal rotation tooth width 9 with a large reduction ratio, and the gear 8 has an intermediate gear 1.
0, the reverse gear 11 is always in mesh with the normal gear 9.
The reversing tooth width 11 is attached to the transmission shaft 12 so as to be rotatable at all times. Then, the forward rotation m wheel 9 and the reverse rotation gear 1
1, a sliding wheel 13 that rotates integrally with the transmission shaft 12 with a spline or the like and can be moved is attached to the transmission shaft 12, and a shift lever 14 that protrudes from the gear box 2 and is set to S9 fff is attached to the transmission shaft 12. The rotational force on the forward or reverse rotation side is transmitted to the transmission shaft 12. The transmission 1112 extends into the chain case 15 provided at the side end of the fuselage via the transmission CJ frame, and connects to the sprocket 16 in the chain case 15 and the support frame attached to the opposite end of the chain case 15. A chain 20 is stretched between the sprockets 1 and 1 of the rotary shaft 18 which is mounted on the lower part of the rotary shaft 17, so that forward or reverse driving force can be selectively transmitted to the rotary shaft 18. ing. On the other hand, a pawl attachment part 21 is fixed to the rotary shaft 18 at a predetermined interval in the height direction as shown in the second diagram Φ).
Each of the claws 23 has a rectangular shape extending symmetrically in a direction orthogonal to the above, and a claw 23 is pivotally supported at the outer end of each via a pivot pin or bolt 22 so as to be swingable in the rotational direction. ”−
The power distribution 23 is shown in FIG. 5 (2). As shown in ([)), the tip side from the vertical blade part 23a is bent to one side in an L-shape to form a horizontal blade part 23b, and from the vertical blade part 23a to the horizontal blade part 231) /J% 4 A blade edge 23c is formed on the side edge in both forward and reverse rotation directions. Also, for the power distribution 23 (=Jt: J hole 23d hole drilling 3
d, and the claw attachment is pivotally supported on the part 21 via a bolt 22. Further, in the pawl mounting portion 21 to which the above-mentioned part 23 is attached, there is a stopper 24 that comes into contact with the side surface of the parking part of the pawl 23 to restrict rotation of the pawl 23 when the rotary shaft 18 rotates in the forward rotation (solid line) direction. is provided, and when the rotary shaft 18 rotates in the opposite direction (in the direction of the dotted line), the pawl 23 separates from the stopper 24, rotates around the pivot bolt 22, and the center of gravity G is stopped at a fixed position by the centrifugal horn. It is meant to be retained. In the above configuration, when the rotary shaft 18 is reversely rotated for mowing work with the pawl 23 attached to the part 21, the pawl 23 becomes free at 22 to the pivot pole 1 and centrifugally rotates. It stays in place due to force, but it rotates in iE direction 1 for tilling work! In this case, the rotational speed is low, the torque applied to the claws 23 is large, and the performance of the claws 23 in reversing the cultivated soil, mulching, etc.
Since the claw 23 must be securely fixed with a cutting angle δ of approximately
] When it is stopped, the horizontal play is caused by the pivot bolt, for example.
It is held down by a leaf spring 25 collinear with 22 and the like. Further, the rotary working machine 1 equipped with the rotary shaft 18 is provided with covers 26 and 27 suitable for the work at the front and rear parts. Furthermore, in order to facilitate the mowing work using the 1.1-power distribution 23, as shown in FIG. aI
l! III Since it is shifted, the back m of the bent part of the claw 23
A cutting angle α is formed with respect to the normal n to the distal horn direction. Therefore, the rear surface m of the bent part of the claw 23 can reduce the escape of the blade without coming into contact with irregularities on the ground surface or stones, etc., and can prevent uncut leaves, as well as the conventional method shown in FIG. It can make it easier to cut down to the root of the grass roots compared to a cutting blade or a cutting force. Next, the operation performed by the AT poop mowing device configured as described above will be explained. First, when driving force is applied to the input shaft 3 from the tractor's l)TO shaft, the intermediate shaft 5 rotates, and the shift lever 1
When the rotary shaft 18 is rotated in the forward direction by rotating the rotary shaft 18 in the forward direction, the claw 23 comes into contact with the stopper 24 of the claw attachment part 21, and the rotation is restricted, and the claw 23 can be rotated in the field in the same way as the well-known tilling claw. You can perform kasuri-u/υ. At this time, intermediate gear 10
The reverse gear 11 is idly rotating on the transmission shaft 12 via the gear 7, and the forward rotation tooth width 9 that meshes with the gear 7 is engaged with the width 13 of WIlh 111!1, rotating the transmission shaft 12, so that the sprocket 16 and the sprocket 19 of the rotary shaft 18, the rotary shaft 18 is rotated at a predetermined rotation speed.Next, the shift lever 14 is operated to the reverse side to rotate the rotary shaft 18 in the reverse direction. When this is done, the pawl 23 rotates around the pivot bolt 22, becomes free, and stays in place due to centrifugal force, making it possible to cut weeds and the like in the same way as conventional 7-rail blades and mower blades. In the embodiment according to the present invention, it is desirable that the rotation speed of the rotary shaft 18 be 200 to 300 rpm during forward rotation, and approximately 800 rpm during reverse rotation.Advantages of the Invention 1 As described above in detail According to the present invention, the rotary shaft of a rotary work machine is configured to be able to rotate at a high speed suitable for mowing work when rotating in the reverse direction, and the shape of the claw is adapted to be suitable for tilling work when rotating in the forward direction and for mowing work when rotating in the reverse direction. This means that one rotary work machine can do the work of two machines, plowing and mowing, and the work can be switched in one go by operating the shift lever. It is efficient and economical, as the labor and time required for attaching stitches using a work machine are greatly reduced.
