Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power spraying machine integrally formed with a hose winding machine capable of winding and unwinding a hose by remote control such as wireless communication.

[0002]

2. Description of the Related Art Conventionally, a power sprayer and a hose winder are integrally formed into a set dynamic injection, and the number of revolutions of the engine of the set dynamic injection is raised or lowered by remote control by wireless or the like to wind the hose. Techniques for taking and feeding are known, and for example,
This is like the technique described in Japanese Utility Model Publication No. 1-95272. When performing remote operation by radio, a transmitter is provided on the operator side and a receiver is provided on the set motion injection side as a remote operation device, and the controller is activated by an operation signal transmitted from the transmitter to the receiver. However, the engine speed and the winding and unwinding speed of the hose can be adjusted.

[0003]

However, since the controller is integrally provided on the set motion injection side in the structure for performing the remote control by radio, contact failure of wiring and parts due to engine vibration, The controller malfunctions due to a short circuit caused by the intrusion of water, noise from the engine spark plug, etc., into the electrical system, overvoltage, or no output. When performing maintenance, it was necessary to disassemble and take out the main body, which was very troublesome and time-consuming.

Further, since the operation is performed by a command from the transmitter on the operator side, the information is one-way,
Information on the set motion injection side (for example, engine speed, battery capacity, remaining fuel amount, etc.) cannot be sent to the operator side, and work efficiency is improved so that fuel runs out during work and work is not interrupted. In order to improve the above, it is preferable that the operator can be informed of the information on the set dynamic injection side.

Further, when a plurality of set motions of the same channel are used and they are close to each other, other transmitting radio waves are received due to the directivity of the receiving antenna of each receiver, and they interfere with each other. It causes operation. Also, when the operator carries the transmitter during work, if the transmitting antenna comes into contact with the body, etc., it will be grounded and the transmission distance will decrease.
There were cases where remote control could not be performed reliably.

Further, since the driving force of the hose winder is obtained from the power of the engine through the crankshaft of the power sprayer, in order to adjust the high and low speeds of the hose wind-up and feeding, Although it is necessary to raise and lower the rotation speed, in consideration of efficiency such as fuel consumption of the engine, it is desirable that the winding speed and the feeding speed of the hose can be adjusted while keeping the rotation speed of the engine constant.

Therefore, in the present invention, the controller on the set dynamic injection side can be attached to the outside of the main body so as not to be affected by the engine, water, etc., and a transmitter / receiver is provided for each of the operator and the remote operation device on the set dynamic injection side. It is equipped with a remote-controlled hose winder that enables reliable transmission / reception of information to each other and enables the operator to display information on the injection side, and the hose winding and unwinding speed can be adjusted with the engine speed kept constant. The purpose is to form a jet.

[0008]

[Means for Solving the Problems] In order to solve the above problems, the following means are used. That is,
The present invention relates to a set dynamic jet in which a power sprayer and a hose winder are integrally configured, and a connection socket is provided at an arbitrary position on the set dynamic jet side to connect to an electrical component, and a cable is connected to the connection socket. It is connected to an operation box accommodating a controller and a transmitter / receiver via a control box so that the operation box can be attached / detached, and a high voltage / high current prevention circuit is provided on the power source side of the controller in the operation box.

Further, in a set dynamic jet in which a power sprayer and a hose winder are integrally configured, a transceiver is connected to a controller on the set dynamic jet side, and a transceiver that can communicate with the transceiver is installed on the operator side. It is possible to send and receive information such as engine operation, engine speed, voltage and remaining fuel amount between the operator and the set dynamic injection. In addition to being composed of a high antenna, a transmitter / receiver antenna that is configured to be freely bendable is provided in the operator side transmitter / receiver, and a continuously variable transmission is provided between the power sprayer and the hose winder, and via the continuously variable transmission. The hose winding and unwinding speed of the hose winding machine can be controlled to change gears.

[0010]

With this configuration, the operation box can be installed away from the main body via the connecting socket (connector) on the set motion injection side and the cable, so that engine vibration and It will not be affected by water. Further, by providing the overvoltage prevention circuit, it is possible to prevent a high voltage (surge voltage or the like) generated due to a defective regulator or grounding of the engine from flowing into the controller. In addition, a transmitter / receiver is provided on the set moving / injecting side and the operator side so that the information on the set moving / injecting side can be transmitted to the transmitter / receiver on the operator side.
Since the operation confirmation lamp, the engine speed meter, the battery checker, and the fuel level gauge can be displayed, the operator can grasp the state of the set dynamic injection at a glance.

Further, since the transmitting / receiving antenna on the set moving / injecting side becomes difficult to receive other operation signals due to its directivity,
Even if the set motions of multiple same channels are used close to each other, the operation signals do not interfere with each other, and the transmitting / receiving antenna on the operator side can be bent and held in a bent shape. It is possible to prevent it from touching the body or the like. Also, since the hose winding and unwinding speed of the hose winder can be controlled via the continuously variable transmission, it is not necessary to raise or lower the engine speed, and the hose winding speed can be kept constant. And the feeding speed can be adjusted.
