Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a hose feeding / removing jet in which the number of revolutions of an engine can be controlled by remote operation such as wireless or wired, and a spray hose can be fed and wound. .

[0002]

2. Description of the Related Art Conventionally, a power sprayer and a hose pay-out winder are integrally configured to form a hose pay-out take-up and jet, and the number of revolutions of an engine is raised and lowered by a remote operation such as wireless or wired to wind the winder. The technology for feeding and winding the spray hose of the reel is
It is known.

[0003]

However, in the above-mentioned prior art, the engine speed of the hose paying-out winding motion injection is
The maximum rotation can be set to a constant value, but if it is less than that, it is set according to the experience and feeling of the operator. For this reason, when there are multiple processes, the number of revolutions should be reduced once in accordance with the proper number of revolutions in one process, and the same number of revolutions should be set when the next engine is set to the same engine revolution as before. Therefore, it was difficult to carry out a stable spraying operation continuously.

Further, the spray hose is constructed so as to be drawn out and wound up by being guided by a hose guide which can be horizontally rotated, and with this structure, when the spray hose is drawn out. The hose guide may rotate due to twisting or curl of the hose, and the spray hose may be extended in various directions, causing the direction of delivery to be unstable and causing twisting, which adversely affects the ejection amount. There is.

Further, the take-up reel is provided with a brake pad which is pressed by a spring force to stop the rotation of the spray hose due to inertia when the spray hose is stopped and when the spray nozzle is opened and closed. In the configuration, inertial rotation of the take-up reel cannot be stopped instantly, and the slack in the spray hose occurs.This slack causes the spray hose to bend and reduce the discharge amount of the chemical liquid, or to wind the spray hose during winding. Problems such as being unable to neatly wind the spray hose around the reel occur. Therefore, the present invention can always set and control the engine speed to a desired value,
It is an object of the present invention to configure a hose feeding / removing jet which can make the feeding direction of a spray hose constant and instantaneously stop the inertial rotation of a take-up reel.

[0006]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, according to the present invention, in a hose pay-out winding dynamic injection in which a remotely controllable power sprayer and a hose pay-up winding machine are integrally configured, a transmitter is provided with an engine speed setting means, and an accelerator lever of the engine is provided. A hose guide that can be rotated horizontally to the left and right to guide the spray hose at the time of feeding and winding, by providing a position detection sensor and rotation means, and making it possible to remotely change the engine speed according to the engine speed setting means A stopper pin is provided, and the stopper pin is configured to restrict the rotation of the hose guide. An electromagnetic brake is provided on the take-up reel around which the spray hose is wound. The electromagnetic brake controls the inertial rotation of the take-up reel. It is configured to stop.

[0007]

Next, the operation will be described. The position detection sensor S for detecting the position of the accelerator lever is provided in the servomotor M connected to the accelerator lever for variably controlling the rotation speed of the engine E. Thus, when the engine speed is set to a desired value (for example, 1000 rpm), the servo motor M operates via the control circuit C, and the position detection sensor S detects the position of the accelerator lever,
The servomotor M operates until the desired value and the value from the position detection sensor S match, and the position of the accelerator lever is controlled so that the desired engine speed is achieved.

Further, since the hose guide 28 is provided with the stopper pin 4, the rotation of the hose guide 28 can be regulated and stopped, and the feeding direction of the spray hose 17 becomes constant. When it is desired to turn the right and left horizontally and change the direction, the stopper pin 4 may be pushed down. Further, when the spray hose 17 is unwound or wound up, when the unwinding or winding is stopped, the unwinding switch K2 or the winding clutch K1 is turned off.
Then, the electromagnetic brake L is automatically operated to stop the take-up reel 3 from continuing to rotate due to inertia, and prevents the spray hose 17 from sagging.
