It is a block diagram of the tire disinfection apparatus which concerns on 2nd Embodiment of this invention.

The first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In FIG. 3, reference numeral 1 denotes a vehicle, and the vehicle 1 is equipped with a vehicle-mounted tire disinfecting device 3 for disinfecting four tires 2 on the front, rear, left and right using a disinfectant solution. The illustrated vehicle 1 is, for example, a truck for transporting feed, but is not limited to this, and may be an ordinary vehicle or the like, regardless of the vehicle type. The disinfectant solution is preferably, for example, an aqueous solution of hypochlorous acid (unsalted hypochlorous acid water), but other disinfectant solutions may be used.

Then, for example, in order to prevent the livestock in the livestock facility from being infected with the infectious disease, before the vehicle (truck) 1 enters the premises of the livestock facility, each of the four tires 2 of the vehicle 1 is a tire disinfecting device. Disinfected by 3.

As shown in FIG. 1, the tire disinfecting device 3 includes an injection nozzle 6 which is a plurality of fluid injection units facing each of the four tires 2 of the vehicle 1 in close proximity to each other. As shown in FIG. 3, one or a plurality (for example, three) of injection nozzles 6 are provided for each tire 2 so as to be spaced from each other on the front side of the tire housing 7 which is the tire facing portion of the vehicle 1. It is attached. The injection port at the tip of the injection nozzle 6 is always open toward the outer peripheral surface of the tire 2. A check valve may be attached to the injection nozzle 6.

The injection nozzle 6 is provided with a nozzle heater 8 which is a heating means for heating the injection nozzle 6. The nozzle heater 8 is made of, for example, a heating wire, and is mounted on the outer surface side of the injection nozzle 6. The injection nozzle 6 is connected to the downstream side of the pipe 11 attached to the bottom side of the vehicle 1.

That is, the pipe 11 has four nozzle mounting pipes 12 corresponding to the number of tires 2 on the downstream side, and the injection nozzle 6 is a pressure valve (shown) at the downstream end of each nozzle mounting pipe 12. It is attached via). The pressure valve (pressure adjusting valve) automatically switches from the closed state to the open state when the pressure in the pipe 11 rises to a preset set pressure (valve opening pressure). The pressure valve is not always necessary, and the injection nozzle 6 may be directly attached to the pipe 11.

Further, a disinfectant liquid tank 16 in which the disinfectant liquid is stored and an antifreeze liquid tank 17 in which the antifreeze liquid is stored are connected to the upstream side of the pipe 11. In the middle of the pipe 11, one pump (pressure feeding means) 18 that also serves as an air pump is provided, and two solenoid valves (three-way solenoid valve) for switching the flow path to which the tanks 16 and 17 are connected are provided. 21 and 22 are provided respectively. Of these two solenoid valves 21 and 22, one of the solenoid valves 22 to which the antifreeze tank 17 is connected has a suction pipe portion 13 that sucks in the air in the driver's seat of the vehicle 1 (air in the vehicle) when the pump 18 operates. It is connected.

Then, based on the flow path switching in the pipe 11 by the two solenoid valves 21 and 22, one fluid selected from the disinfectant liquid, the antifreeze liquid and the air is supplied into the pipe 11.

The disinfectant tank 16 can store a predetermined amount of disinfectant, and the disinfectant tank 16 is a tank heater (heating means) for preventing freezing to prevent the disinfectant in the tank 16 from freezing. 25 are provided. Further, a discharge valve 26 for discharging the disinfectant solution in the tank 16 to the outside is connected to the disinfectant liquid tank 16, and the discharge valve 26 is provided with a valve heater 27.

If the tank heater 25 for preventing freezing is not provided, the disinfectant is discharged after each use of the vehicle 1, and the disinfectant is put into the disinfectant tank 16 when the vehicle 1 is used next time.

The antifreeze tank 17 can store a predetermined amount of antifreeze liquid, and like the disinfectant tank 16, a discharge valve 28 for discharging the antifreeze liquid in the tank 17 to the outside is connected to the antifreeze liquid tank 17. The discharge valve 28 is provided with a valve heater 29. Since the antifreeze liquid in the antifreeze tank 17 has a lower freezing point than the disinfectant liquid in the disinfectant tank 16, it does not freeze even in winter in a cold region below the freezing point.

Further, the tire disinfecting device 3 includes at least a nozzle heater 8, a pump 18, and a control means 31 for controlling the solenoid valves 21 and 22. An operating means (remote control switch) 32 arranged in the driver's seat of the vehicle 1 is electrically connected to the control means 31. Then, when the driver in the driver's seat of the vehicle 1 operates the operating means 32, the control means 31 appropriately controls the nozzle heater 8, the pump 18, and the solenoid valves 21 and 22 based on this operation.

As shown in FIG. 2, the operating means 32 is, for example, a plurality of switches (push button switches) that can be pushed and operated by a driver in the driver's seat of the vehicle 1 while driving the vehicle 1, that is, fully automatic. It has a switch 35 for disinfectant, a switch 36 for disinfectant, a switch 37 for air, a switch 38 for antifreeze, and a switch 39 for a nozzle heater. The nozzle heater switch (heating means operation unit) 39 may be provided on the nozzle heater 8 side.

Further, electric power is supplied from the spare battery 40 provided separately from the battery of the vehicle 1 to the heaters 8, 25, 27, 29 of the tire disinfecting device 3, the motor portion of the pump 18, and the like. The capacity of the battery of the vehicle 1 may be increased. Further, as for the tank heater 25 for preventing freezing, electric power from an external power source may be used.

Next, the operation of the tire disinfecting device 1 and the like will be described.

For example, a case where the tire disinfecting device 1 is used during the winter in a cold region such as Hokkaido will be described.

During the winter in cold regions, the temperature is below freezing and a lot of snow falls, so the meltwater scattered from the rotating tire 2 adheres to the tip of the injection nozzle 6 located around the tire 2 of the vehicle 1. It freezes.

For example, a driver who gets on the driver's seat of a vehicle 1 which is a truck loaded with feed is fully automatic of the operation means 32 in the driver's seat while slowing down and slowing down before entering the premises of the livestock facility. Press the switch 35 once to operate.

Then, as shown in FIG. 4A, first, the nozzle heater 8 is operated for a preset set time, and the injection nozzle 6 is heated. As a result, the ice adhering to the tip of the injection nozzle 6 is thawed, and the clogging of the ice is cleared.

Next, the injection nozzle 6 injects the disinfectant liquid from the disinfectant liquid tank 16 pumped through the pipe 11 toward the tire 2 for a preset set time based on the operation of the pump 18. As a result, the tire 2 of the vehicle 1 is disinfected with a disinfectant solution over the entire circumference thereof, and deposits (snow, mud, etc.) adhering to the outer peripheral surface are removed.

Next, the injection nozzle 6 injects the air in the driver's seat of the vehicle 1 pumped through the pipe 11 toward the tire 2 for a preset time based on the operation of the pump 18.

As a result, all the disinfectant liquid remaining in the pipe 11 and the injection nozzle 6 is discharged to the outside. That is, by injecting air, excess water is discharged from the inside of the pipe 11 and the inside of the injection nozzle 6. At this time, the droplets of the disinfectant liquid adhering to the vehicle 1 are removed by the injection of air.

Next, the injection nozzle 6 injects the antifreeze liquid from the antifreeze liquid tank 17 pumped through the pipe 11 toward the tire 2 for a preset set time based on the operation of the pump 18.

As a result, the inside of the pipe 11 and the inside of the injection nozzle 6 are filled with the antifreeze liquid. This antifreeze liquid has a low freezing point (for example, −30 degrees or less), does not freeze in the pipe 11 and the injection nozzle 6, and maintains the liquid state. Therefore, at the next spraying of the disinfectant, the disinfectant smoothly flows in the pipe 11 and the injection nozzle 6 while pushing out the antifreeze.

In this way, when the driver of the vehicle 1 operates the fully automatic switch 35, the injection nozzle 6 automatically sequentially injects the disinfectant liquid, the air, and the antifreeze liquid after the nozzle heater 8 operates.

Further, as shown in FIG. 4B, the driver of the vehicle 1 presses and operates the switches 36, 37, 38, 39 instead of the fully automatic switch 35, as in the case of the fully automatic switch. In addition, it is possible to disinfect the tire 2.

That is, the driver who gets on the driver's seat of the vehicle 1 first presses and operates the nozzle heater switch 39. Then, the nozzle heater 8 operates for a preset time, the injection nozzle 6 is heated, and the clogging of ice is cleared. After that, the driver pushes the disinfectant switch 36 for a desired time.

Then, the injection nozzle 6 injects the disinfectant toward the tire 2 only while the disinfectant switch 36 is pressed. That is, the injection nozzle 6 injects the disinfectant liquid only while the disinfectant liquid switch 36 is pressed, and when the disinfectant liquid switch 36 is released, the injection of the disinfectant liquid from the injection nozzle 6 is stopped.

Next, the driver who gets on the driver's seat of the vehicle 1 pushes the air switch 37 for a desired time.

Then, only while the air switch 37 is being pushed, the injection nozzle 6 injects air toward the tire 2, the disinfectant liquid in the pipe 11 and the injection nozzle 6 is discharged to the outside, and the vehicle 1 Droplets of disinfectant adhering to the water are removed.

Next, the driver who gets on the driver's seat of the vehicle 1 pushes the antifreeze switch 38 for a desired time.

Then, the injection nozzle 6 injects the antifreeze liquid toward the tire 2 only while the antifreeze liquid switch 38 is pressed, and the inside of the pipe 11 and the inside of the injection nozzle 6 are filled with the antifreeze liquid.

In this way, by sequentially pressing and operating the switches 36, 37, 38, and 39, the tire 2 of the vehicle 1 can be disinfected even in the winter in a cold region.

On the other hand, when the temperature does not fall below the freezing point and there is no risk of the disinfectant freezing (summer period, etc.) other than the winter period, as shown in FIG. 4 (c), get on the driver's seat of the vehicle 1. The driver presses only the disinfectant switch 36 for a desired time to inject the disinfectant from the injection nozzle 6 (the disinfectant is ejected only while the disinfectant switch 36 is pressed, and the injection is stopped when the disinfectant switch 36 is released). , The tire 2 may be disinfected.

Further, according to such a tire disinfecting device 1, since the injection nozzle 6 facing each tire 2 of the vehicle 1 can inject disinfectant liquid, air and antifreeze liquid, disinfection even in the winter period in a cold region. It is possible to prevent the liquid from freezing and appropriately disinfect the tire 2 of the vehicle 1. Therefore, a sufficient disinfecting effect can be obtained even during low-temperature drying in which the activity of bacteria and viruses becomes active, and it is possible to appropriately prevent livestock in livestock facilities from being infected with an infectious disease.

Further, the operating means 32 installed in the driver's seat of the vehicle 1 has at least a fully automatic switch 35, a disinfectant switch 36, an air switch 37, an antifreeze switch 38, and a nozzle heater switch 39, so that the operability is operability. Is good, and it can respond appropriately to the winter and summer periods.

Further, since the nozzle heater 8 for heating the injection nozzle 6 is provided, it is possible to appropriately eliminate the clogging of the injection port due to the ice adhering to the tip of the injection nozzle 6.

Next, a second embodiment of the present invention will be described with reference to FIG.

The tire disinfecting device 3 shown in FIG. 5 includes an air tank (air tank) 41 in which compressed air (preferably dry air) is stored, in addition to the disinfecting liquid tank 16 and the antifreeze liquid tank 17. The air tank 41 is connected to the solenoid valve 22 via a connecting pipe portion 42. Then, when the fully automatic switch 35 is operated and when the air switch 37 is operated, the air from the air tank 41 is injected from the injection nozzle 6 through the pipe 11. Other configurations are basically the same as those of the first embodiment.

The air tank 41 may be provided with a tank heater (heating means) for heating the air in the air tank 41.

When the vehicle (truck) 1 is provided with an air tank (compression tank) for braking, the air from the air tank of the vehicle 1 may be supplied into the pipe 11.

On the other hand, in any of the embodiments, the configuration in which the pump as the pumping means is one is described, but for example, a configuration in which three pumps corresponding to each of the disinfectant solution, the air, and the antifreeze solution may be provided.

Further, the pump is not limited to the one having a motor unit driven by electric power, and may be, for example, a pump operated by power from the engine of vehicle 1.

Further, the fluid injection portion facing the tire 2 is not limited to the injection nozzle 6 that injects the fluid at a high pressure, and may be, for example, a pipe end portion (downstream end portion of the pipe) that injects (discharges) the fluid at a low pressure.

Further, a pipe heating means (pipe heater) for heating the pipe 11 through which the disinfectant liquid, air and antifreeze liquid flow may be provided on the outer peripheral side of the pipe 11.

Further, as the heating means for heating the pipe 11 and the injection nozzle 6, warm air from the air conditioner of the vehicle 1 may be used.

Further, the operating means 32 sets, for example, an operation unit for setting the operating time of the nozzle heater 8 and each injection time (disinfectant injection time, air injection time, antifreeze injection time) in the case of full automation. It may have an operation unit for doing so.

Further, the tire disinfecting device 1 is not limited to disinfecting only the tire 2 of the vehicle 1, and disinfects other parts of the vehicle 1 such as the tire housing 7 and the bottom of the vehicle 1 in addition to the tire 2. You may do so.

Further, for example, the antifreeze tank 17 can be used as a disinfectant tank during the summer, and a discharge valve 28 and a valve heater 29 are also required for this purpose. If the antifreeze tank 17 is not used as a disinfectant tank, the discharge valve 28 and the valve heater 29 are not always necessary.
