is located. The manual winding switch 11 is used when the winding switch 11 is operated manually or when the battery 26 is discharged and the radio control reception control device B does not operate. In this case, since the battery 26 is discharged, the motor of the engine E cannot be started, but it can be started using the starting rope 28. Due to this start, engine E
When the engine E rotates, the electromagnetic clutch 53 can be engaged by the electric power generated by the generator coil attached to the engine E. This results in
This made it possible to drive the winder and wind up the hose A using the hose alignment device.

A direction changing body 13 whose direction can be changed from side to side is pivotally supported on a guide body 43 which is left and right by the feed shaft in the feed shaft case 8 . The guide body 43

The brake friction rod 9 is pivotally supported at its upper end by a brake pivot shaft 25, and the upper end surface of the hose A comes into contact with the brake friction rod 9 and moves for winding and pulling out. Then, due to the winding force and pulling force, the brake friction rod 9 is moved to the brake pivot shaft 25.
The brake shoe 1 rotates around , and is fixed to the tip of an arm connected to the brake friction rod 9.
0 is released from contact with the edge of the drum of the hose winding drum 3, and the brake is released.
Conversely, when the winding/drawing operation is stopped, the brake shoe 10 is brought into contact with the drum edge of the hose winding drum 3 by the biasing spring, thereby stopping unnecessary rotation of the hose winding drum 3. .

A receiving antenna 16 is disposed at the base of the feed shaft case 8 near the side plate 12.

The drive system for the hose winding drum 3 from the PTO pulley 42 will be explained.

As safety covers for these drive sections, a set drive section cover 22, a lower cover 21 on the winder side, and an upper cover 41 on the winder side are arranged.

Next, FIG. 5 is an enlarged side view of the radio control box 7, FIG. 6 is a rear view of the radio control reception and control device B, FIG. 7 is a perspective view of the radio control transmitter C in an operating state, and FIG. is a side view of the radio control transmitter C.

The radio control transmitter C shown in FIGS. 7 and 8 is provided with five switches: a power switch 48, a winding switch 49, a starting switch 50, a high speed switch 51, and a low speed switch 52.

By pressing these five switches, radio waves for radio control are transmitted, and the engine start, winding, and raising/lowering of the engine rotation of the set dynamic injection equipped with automatic hose winding machine of the present invention are performed. . Eventually, the engine E can be stopped due to the decrease in engine rotation.

And the method of operating the radio control transmitter C is as follows.
The structure is such that two switches must be operated at the same time. That is, the configuration is such that radio waves are emitted only when the power switch 48 is pressed, and other switches are operated in conjunction with the depression of the power switch 48.

First, when starting the engine E, the power switch 48 and the high speed switch 51 are used to raise the accelerator lever, and then the power switch 48 and the high speed switch 51 are used to raise the accelerator lever.
and presses the start switch 50. As a result, the starting motor device 27 of the engine E rotates, and the engine E starts.

Next, if you want to increase the engine speed, press the power switch 48 and the high speed switch 51 at the same time, and if you want to decrease the engine speed or stop the engine E, press the power switch 48 and the low speed switch 52.
Press the button. Also, in the rotation state of engine E,
When winding with a hose alignment device,
The power switch 48 and the winding switch 49 are pressed. This turns on the electromagnetic clutch 53, rotates the hose winding drum 3, and drives the hose alignment device left and right.

When winding up the hose A, the electromagnetic clutch 53
The driving force of the automatic winder is transmitted through this connection.

1, and the power switch 48 and the winding switch 4
While both 9 are pressed, the electromagnetic clutch 53 is engaged and the winding operation is performed.

Conversely, when pulling out hose A, the operator pulls and moves the end of hose A. Since the electromagnetic clutch 53 is not engaged, the hose winding drum 3 can rotate and the hose can be pulled out. Since the alignment device moves with the rotation of the hose winding drum 3, the hoses can be drawn out in an orderly manner.

A battery lamp 56 is disposed in the radio control transmitter C, and is configured to be turned on by pressing the power switch 48 if there is sufficient battery capacity in the radio control transmitter C. . If the battery is discharged,
The battery lamp 56 does not light up.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, in the case of conventional radio control devices, simply pressing one operation button on the radio control transmitter C transmits an operation signal, so the operator can remotely control the device by simply touching the switch. was carried out,
Unexpected hose winding and engine starting occur.
There was a risk of personal injury occurring near the machine.

On the other hand, in the case of the present invention, when operating the radio control transmitter C, the power switch 48 must be turned on.
At the same time, since it is now necessary to press two switches simultaneously, in the event of a malfunction, it is impossible to press two switches at the same time, which reduces the possibility of an accident occurring. It was possible to do so.

Second, when operating, be sure to turn off the power switch 48.
Because the configuration was configured so that other switches would only operate after pressing the button and turning on the power to radio control transmitter C, the power to radio control transmitter C was always turned off, resulting in forgetting to turn it off. This eliminates unnecessary battery discharge.
