Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle tire cleaning device.

[0002]

[Prior art]

 Examples of disclosure regarding a vehicle tire cleaning device include Japanese Utility Model Laid-Open No. 58-179262, Japanese Utility Model Laid-Open No. 58-196254, Japanese Utility Model Laid-Open No. 59-158550 and the like.

Conventionally, in order to clean mud and other foreign matter adhered to a tire of a vehicle, a water injection device including an injection nozzle arranged near the tire, a water tank, and a water pump is mounted on the vehicle and required. At such times, a method has been adopted in which high pressure is applied to the water from the water tank by a water pump, and the water is injected from the injection nozzle toward the tire through the pipe.

[0004]

[Problems to be solved by the device]

 However, it has not been easy to remove mud and the like stuck to the tires of the wheels, especially the rear wheels, by the conventional technique of only injecting high-pressure water as described above.

Accordingly, the object of the present invention is to provide a vehicle tire cleaning device that can easily and quickly remove even mud stuck to the tire, except for the above-mentioned drawbacks of the prior art.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has the following configuration. That is, a water injection device including a water tank, an injection nozzle provided near the tire, and a water pump for injecting water in the water tank from the injection nozzle toward the tire through a pipe, and above the tire. A brush that is arranged in the vicinity and that comes into contact with and separates from the tire via a link, an actuator that drives the link so that the brush presses against the tire, and the brush separates from the tire and returns to the original position. And a brush device having a return spring for driving the link, and a signal from the water level sensor and the engine rotation speed sensor, the amount of water in the water tank is a certain value or more and the engine rotation speed is a certain value or less. Sometimes it is composed of the water pump and control means for operating the actuator.

[0007]

[Action]

 According to the vehicle tire cleaning apparatus of the present invention, when the water pump and the actuator start operating according to the control program of the control means, high pressure water is injected from the injection nozzle to the tire, and at the same time, the brush is pressed against the tire and then separated. Repeat the above operation to scrape off the mud that has stuck to the tires. Therefore, mud can be washed off easily and quickly.

[0008]

【Example】

 FIG. 1 is a model diagram showing the configuration of an embodiment of the present invention. As is clear from the figure, the vehicle tire cleaning apparatus of the present invention comprises a power system, a water channel system, an electric system, and a compressed air system. In the figure, the electric system wiring is shown by a solid line, and the compressed air system piping is shown by a dashed line.

First, the configuration of the power system will be described. 1 is an engine, 2 is an engine rear PTO (Rear Power Take Off = rear power take-off device, which is used when the engine is used as a power source other than the main power), Is an electromagnetic clutch.

Next, regarding the water channel system, 4 is a water tank, 5 is a water pump, 6 is a pressure regulating valve, 7-1 and 7-2 are directional valves, and 8-1, 8-2 and 8-3 are nozzles. Is. In this embodiment, nozzles are attached to five locations on each of the left and right sides of one vehicle, for a total of ten locations. By the way, 9-1 and 9-2 are existing or special fenders (Fender).

On the other hand, when explaining the electric system, 10 is a battery, 11 is a main key, 12 is a cleaning switch, 13 is a timer, 14 is a control panel, 15 is an engine speed sensor, 16 is a water level sensor, and 17 is a water level monitor. Alarm lamp, 18 is earth.

Regarding the compressed air system, 19 is a compressed air tank, 20 is an electromagnetic valve, 21 is an air cylinder, 22 is a return spring, 23-1 and 23-2 are links, and 24-1 and 24-2 are It is a brush.

The correspondence between the names of the parts and members described in the section [Means for Solving the Problems] and the names of the parts and members in the present embodiment is extremely clear, and therefore the description thereof is omitted. . However, the component "actuator" described in [Means for Solving the Problems] may have any driving energy source as long as it has a function of driving the link so that the brush is pressed against the tire. In the example, the "air cylinder 21" corresponds to the "actuator", and the drive energy source is limited to compressed air.

Now, FIG. 2 is a flow chart showing an operation procedure when the tire is washed. The flow of tire cleaning will be described below with reference to FIG. α. First, turn on the main key 11. Only this operation is performed manually, but the operations after the next β are all automatically executed under the control of the control panel 14.

Β. The water level sensor 16 determines whether or not the amount of water in the water tank 4 has reached a certain value. γ. If the determination result in β is “no”, the operation is ended (π) by simply turning on the water level monitor alarm lamp 17.

Δ. If the determination result in β is “yes”, the cleaning switch 12 is turned on. ε. When the cleaning switch 12 is turned on, the timer 13 is started and the following operations are continued within a preset time T.

Λ. The engine speed sensor 15 determines whether or not the engine speed is below a certain value. If the determination result at λ is “no”, the operation ends (π).

Μ. If the judgment result at λ is "yes", the electromagnetic clutch 3 is engaged, and the water from the water tank 4 is pressurized by the water pump 5, and the front wheel nozzle 8-1, etc. It is injected toward the tire from the nozzles 8-2, 8-3. The control panel is set in advance to switch whether pressurized water is sent only to the front wheel nozzles 8-1, etc., only to the rear wheel nozzles 8-2, 8-3, etc., or to all nozzles. Drive the directional control valve 7-1 and / or 7-2 according to the program.

Ν. Next, the electromagnetic valve 20 is started, whereby the operation of sending the high-pressure air from the compressed air tank 19 to the air cylinder 21 and the operation of suspending the sending are alternately repeated. As a result, when the high pressure air is sent, the air cylinder 21 brings the brushes 24-1 and 24-2 into pressure contact with the tire via the links 23 -1 and 23-2, respectively, and the high pressure air to the air cylinder 21 is also supplied. The return spring 22 when the feeding of the brushes is stopped drives the brushes 24-1 and 24-2 to separate from the tires and return to their original positions via the links 23-1 and 23-2, respectively. By repeating this operation, mud and the like stuck to the diamond is almost completely scraped off.

Π. After the above operation is continued for the time T set in the timer 13, the cleaning operation is finished.

[0021]
