Description

[Detailed Description of the Invention] The present invention relates to an electric management machine, and particularly to an electric management machine having a connecting portion between a base unit and a mounting work machine.

In other words, the PTO shaft is formed into an inner and outer dual shaft structure, and the inner shaft is fitted integrally with the outer shaft in the rotational direction and can be freely pulled out in the axial direction. This is an electric management machine with a connecting part.

Since the present invention is constructed as described above, when no work equipment is attached to the base unit, the inner shaft can be pushed into the outer shaft and capped in the case to prevent dirt and rust.
Since the inner shaft, that is, the PTO shaft, does not protrude when not needed, the inner shaft does not get in the way, and when a work machine is attached, the inner shaft can be pulled out from the outer shaft and the inner shaft can be used directly as a PTO shaft.

The embodiments shown in the drawings will be described below. First, the electric power management machine that is the base unit will be explained. Fig. 1 is an overall side view of the electric power management machine, and Fig. 2 is a cross-sectional view of the same.

In the figure, 1 is a high-speed rotating commutator electric motor supported on a fender 5 by a support (not shown), 2 is a transmission reduction case connected to the motor 1, and 3 is an axle case, which is a chain case, with the upper end at the rear. Fixed in a tilted manner.

4 is a tilling rotary which is an attachment pivotally supported on the lower end of the axle case 3;

Reference numeral 5 designates a fender which is removably fixed and supported by the axle case 3 and covers the upper area of the rotary 4, and 6 is a holder for a handle 7 provided on the rear left and right sides of the fender 5.

The lower end of the handle 7 is pivoted 8 to the holder 6,
The handle 7 is attached with a bolt 10 that fits into an arcuate slit groove 9 of the holder 6 so that the angle of inclination can be adjusted.

Reference numeral 11 denotes a resistance rod formed at the lower rear of the fender 5, which is configured to rotate the rotary 4 by driving the electric motor 1 to perform plowing work and at the same time cause the machine to travel.

The deceleration case 2 is constructed by separately forming left and right case bodies 2a and 2b that are integrally fixed together via bolts 12, and the right case 2b is connected to the axle case 3 via bolts 13 and flanges 14. connected to the top end.

Furthermore, the fender 5 is attached to the middle of the axle case 3 via a bracket 15 and bolts 16, and an axle 18 is supported at the lower end of the case 3 via a housing 17. A tilling claw 22 and a guide ring 23 of this rotary 4 are attached via a shaft 21.

In short, this management body uses the axle case 3 as the main component, and the fender 5 is attached to the center of the case 3 on both left and right sides via brackets 15 and bolts 16, and the right case is attached to the upper end of the case 3 via bolts 13 and flanges 14. The electric motor 1 is fixedly supported on the end of the right case body 2b, so that the motor 1, the reduction case 2, the rotary 4, and the fender 5 are fixedly supported. , the handle 7 and the resistance rod 11 are all attached to the axle case 3.
It is provided so that it is supported by the

On the other hand, a transmission mechanism in which a belt is stretched between a pulley 28 of an input shaft 27 and a pulley 29 of an output shaft 30 is built in the speed reduction case 2 .

Further, a transmission mechanism in which a chain is stretched between a sprocket 31 of the output shaft 30 and a sprocket 32 of the axle 18 is built in the axle case 3.

The electric control machine of the present invention is an improved output shaft 27 of the reduction case 2 in the electric control machine as described above, and the output shaft 27 has a dual-shaft structure, with the inner shaft rotating in the direction of rotation with respect to the outer shaft. is integrally fitted so that it can be freely pulled out in the axial direction.

That is, 33 is a housing for connecting the deceleration case 2 to the motor 1, and an outer shaft 34 is rotatably mounted on this housing as shown in FIGS. 3 and 4.
35 and 36 are the bearings.

37 is a gear corresponding to the pulley 28 of the electric management machine, and the corresponding pulley 29 is also a gear.

38 is fitted into the inner hole 34a of the outer shaft 34 integrally in the rotational direction and freely drawn out in the axial direction.
A structure is adopted in which a ball 40 that fits into the ball 9 is pressed by a spring 41. However, spline fitting may be used, or regulation may be performed using serrations, keys, etc.

A screw hole 46 is formed at the end of the inner shaft 38, and a knob screwed into the screw hole 46 can be used to tighten the outer shaft 3.
4, the inner shaft 38 can be freely pulled out, and a stopper device (not shown) prevents it from being pulled out more than necessary.

In the state shown in FIG. 3, the inner shaft 38 is housed in the outer shaft 34, and the housing case 33 is covered with a cap 42 to prevent it from being contaminated by dust from the outside.

To install a working machine using the electric management machine as a base unit, remove the cap 42 as shown in Fig. 4, screw the grip device into the screw hole 46, and insert the inner shaft 38.
is pulled out from the outer shaft 34, the pulley 43 is attached thereto via the link 45, and the bolt 44 is inserted into the screw hole 46.
By screwing in, you can use this as a power source to move another work machine together with the rotary control machine.

As described above, power can be extracted as a power source for another working machine, and the PTO shaft can be stored out of the way when another working machine is not used.
