Description

[Detailed description of the invention] "Industrial application field" This invention equips the machine with a prime mover such as an electric motor, and uses the driving force of the prime mover to run the machine for various management tasks such as plowing, ridge-building, etc. Regarding a management machine that performs the following.

``Prior Art'' Conventionally, there have been small control machines with wheels or tiller claws attached to the axle.

"Problems to be Solved by the Invention" The conventional technology mentioned above is small in size and has a low horsepower output, and even if it is configured to attach a work machine for management work such as a lawn mower, the horsepower is insufficient. Since both the axle and the working machine cannot be driven, the types of attachment of the working machine are restricted, and management work is limited.

``Means for Solving the Problems'' However, the present invention provides a plurality of power take-off shafts that are interlocked and connected to the same prime mover, connects an axle to one of the power take-off shafts via a clutch, and manages the A work implement is configured to be detachably connected to the other power extraction shaft, and an interlocking member is provided between the work implement and the clutch, and the interlocking member is actuated by the attached work implement to engage the clutch. It is characterized by being constructed so as to reduce the

``Function'' Therefore, by attaching tilling claws to the axle, it is possible to perform tilling work, and by attaching a working machine such as a mower, it is possible to drive the working machine while pushing and pulling by hand. Even if the prime mover is a small one with low horsepower, the types of installation of work equipment can be more easily diversified than before, and it is easy to expand the content of management work and improve work efficiency. At the same time, it is possible to easily reduce the size of the motor and the manufacturing cost.

Further, the axle case 3 is provided with a small diameter sprocket 26 attached to the input shaft 25, a large diameter sprocket 28 attached to the axle 27, and a chain 29 for tensioning between these sprockets 26 and 28. 30, the clutch case portion 31 of the axle case 3 is fixedly supported, and the input shaft 25 is interlocked and connected to the output shaft 20 via the pawl clutch 32. The running wheel 4 is pivotally supported by the axle 27, which can be used for intercultivation and ridge raising by providing an attachment, and the running wheel 4 is rotated by the motor 1 to cause the machine to travel.

As shown in FIG. 4, the output shaft 20 has a power take-off shaft 20 attached to a cylindrical shaft 20a to which a sprocket 21 is attached.
b is spline-fitted to the extraction shaft 2.
The movable pawl plate 32a of the clutch 32 is supported by the shaft portion 20c at one end of the clutch 32 via a compression spring 33,
The fixed claw plate 32b of the clutch 32 supported on the input shaft 25 is normally pressurized by the spring 33 to press the movable claw plate 32a, thereby transmitting power between the shafts 20b and 25.

Furthermore, the movable pawl plate 32a is interlocked and connected to a clutch cutting mechanism 34, and the cutting mechanism 34 has a shifter 36 whose intermediate portion is supported by a fixed fulcrum shaft 35 and whose one end engages with the pawl plate 32a; A shift rod 38 is guided and supported by a fixed guide 37 and has one end connected to the other end of the shifter 36. When a contact portion 38a provided at the other end of the shift rod 38 is pressed, the shifter 36 is swung and the shift rod 38 is moved. The plate 32a, 32b is disengaged, that is, the clutch 32 is disengaged.

On the other hand, a pawl clutch 39 is also provided on the other end side shaft portion 20d of the take-out shaft 20b, and the pawl clutch 39 is interlocked with the mower 10. These claw plates 39a and 39b are respectively attached to the input shaft 40 of the mower 10 and are provided so as to mesh with each other when the drive case 41 of the mower 10 is mounted on the reduction case 2. The drive case 41 is connected to the cutting blade case 43 via a transmission pipe 42, and
The input shaft 40 includes a bevel gear 44 and a bevel shaft 45.
In addition, when the drive case 41 is attached to the deceleration case 2 by interlockingly connecting it to the mowing blade 47 via a flexible wire 46 or the like, the shift rod 3
The side surface of the transmission pipe 42 is brought into contact with the contact portion 38a of the mower 8, and the clutch 32 is disengaged to rotate only the mowing blade 47.

As is clear from the above, a plurality of power take-off shaft parts 2 are interlocked and connected to the motor 1 which is the same prime mover.
0c and 20d are provided, and one power take-off shaft portion 20c
The axle 27 is connected to the axle 27 via the clutch 32, and the mower 10, which is a work machine for maintenance work, is detachably connected to the other power take-off shaft 20d, and the shift rod 38, which is an interlocking member, The shift rod 3 is moved by the mower 10 which is installed between the mower 10 and the clutch 32.
8 to disengage the clutch 32.

The present embodiment is constructed as described above, and when the mower 10 is not installed in the deceleration case 2, the clutch 32 is always on and the rotational force of the motor 1 is transferred to the axle 4. The information is transmitted and the aircraft moves.

On the other hand, when the mower 10 is installed in the deceleration case 2, the claw plates 39a and 39b are engaged and the clutch 39 is in the engaged state, and the pipe 4
2 comes into contact with the abutting portion 38a of the shift rod 38, causing the shift rod 38 to move backward in the direction of the solid line arrow in FIG. As a result, as shown in Fig. 4, the shifter 36
swings counterclockwise to move the movable claw plate 32a of the clutch 32 backward against the spring 33, and move the fixed claw plate 3
This clutch 32 is disengaged from the clutch 2b.
When the mower 10 is turned off, it stops running and the mower 10
only is in the driving state. Therefore, even if the horsepower of the motor 1 is small, this power is not consumed for running, but is all effectively consumed by the mower 10, and work can be performed satisfactorily without causing problems such as overload operation.

"Effects of the Invention" As is clear from the above embodiments, the present invention provides a plurality of power take-off shaft parts 20c and 20d that are interlocked and connected to the same prime mover 1, and one power take-off shaft part 2
