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 sides with a disinfectant. Although the illustrated vehicle 1 is, for example, a truck for transporting fodder, it is not limited to this and may be an ordinary vehicle or the like, regardless of the type of vehicle. The disinfectant is preferably an aqueous solution of hypochlorous acid (unsalted hypochlorous acid water), but other disinfectants may be used.

For example, in order to prevent livestock in a livestock facility from being infected with an 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 disinfected with a tire disinfecting device. 3 to disinfect.

As shown in FIG. 1, the tire disinfecting device 3 includes injection nozzles 6, which are a plurality of fluid injection portions that closely face each of the four tires 2 of the vehicle 1. As shown in FIG. As shown in FIG. 3, one or a plurality of (for example, three) injection nozzles 6 are provided for each tire 2, and are spaced apart from each other on the front side of the tire housing 7, which is the tire facing portion of the vehicle 1. installed. An 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 heating means for heating the injection nozzle 6 . The nozzle heater 8 is made of a heating wire, for example, and is attached to the outer surface of the injection nozzle 6 . The injection nozzle 6 is connected to the downstream side of a pipe 11 attached to the bottom side of the vehicle 1 .

That is, the pipe 11 has four nozzle mounting pipe portions 12 corresponding to the number of tires 2 on the downstream side, and the injection nozzle 6 is connected to a pressure valve (not shown) at the downstream end of each nozzle mounting pipe portion 12. (not included). The pressure valve (pressure regulating valve) automatically switches from a closed state to an open state when the pressure in the pipe 11 rises to a preset set pressure (valve opening pressure). The pressure valve is not necessarily required, and the injection nozzle 6 may be directly attached to the pipe 11.

Further, a disinfectant tank 16 storing disinfectant and an antifreeze tank 17 storing antifreeze are connected to the upstream side of the pipe 11 . In the middle of the pipe 11, one pump (pumping means) 18 that also serves as an air pump is provided, and two solenoid valves (three-way solenoid valves) for switching flow paths connecting the tanks 16 and 17 are provided. 21 and 22 are provided respectively. Of these two solenoid valves 21 and 22, one of the solenoid valves 22 connected to the antifreeze tank 17 has a suction pipe portion 13 for sucking the air in the driver's seat of the vehicle 1 (the air inside the vehicle) when the pump 18 is in operation. It is connected.

Then, based on the switching of the flow path in the pipe 11 by the two electromagnetic valves 21 and 22, the pipe 11 is supplied with one fluid selected from the antiseptic solution, the antifreeze solution and the air.

The disinfectant tank 16 is capable of storing a predetermined amount of disinfectant, and the disinfectant tank 16 is provided with an anti-freezing tank heater (heating means) for preventing the disinfectant in the tank 16 from freezing. 25 are provided. The disinfectant tank 16 is connected to a discharge valve 26 for discharging the disinfectant in the tank 16 to the outside, and the discharge valve 26 is provided with a valve heater 27 .

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

The antifreeze tank 17 can store a predetermined amount of antifreeze, and like the disinfectant tank 16, the antifreeze tank 17 is also connected to a discharge valve 28 for discharging the antifreeze in the tank 17 to the outside. A valve heater 29 is provided for the discharge valve 28 . The antifreeze in the antifreeze tank 17 has a lower freezing point than the disinfectant in the disinfectant tank 16, so it does not freeze even in winter in cold climates where the temperature drops below freezing.

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

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

Further, electric power is supplied to the heaters 8, 25, 27, 29 of the tire disinfecting device 3 and the motor portion of the pump 18 from a spare battery 40 provided separately from the battery of the vehicle 1. FIG. It should be noted that the capacity of the battery of the vehicle 1 may be increased. Further, electric power from an external power source may be used for the tank heater 25 for anti-freezing.

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

For example, a case of using the tire disinfection device 1 during winter in a cold region such as Hokkaido will be described.

During the winter in cold regions, the air temperature drops below freezing and a lot of snow falls, so the tips of the injection nozzles 6 positioned around the tires 2 of the vehicle 1 are covered with melted snow water splashed from the rotating tires 2. Freezing.

For example, a driver in the driver's seat of a vehicle 1, which is a truck loaded with feed, slows down and slows down before entering the premises of a livestock facility, and fully automates the operation means 32 in the driver's seat. switch 35 is pressed once.

Then, as shown in FIG. 4A, first, the nozzle heater 8 is activated 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 melted, and the clogging with ice is eliminated.

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

Next, the injection nozzle 6 injects the driver's seat air of the vehicle 1 pressure-fed 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 remaining in the pipe 11 and the injection nozzle 6 is discharged to the outside. In other words, excess moisture is discharged from the inside of the pipe 11 and the inside of the injection nozzle 6 by the air injection. Also, at this time, droplets of the disinfectant adhering to the vehicle 1 are removed by air injection.

Next, the injection nozzle 6 injects the antifreeze liquid from the antifreeze tank 17 pressure-fed through the pipe 11 toward the tire 2 for a preset 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 has a low freezing point (for example, −30° C. or less), and does not freeze inside the pipe 11 and the injection nozzle 6 and maintains a liquid state. Therefore, when the disinfectant solution is sprayed next time, the disinfectant solution smoothly flows through the pipe 11 and the spray nozzle 6 while pushing out the antifreeze solution.

In this manner, when the driver of the vehicle 1 operates the fully automatic switch 35, the injection nozzle 6 automatically injects disinfectant, air, and antifreeze in sequence after the nozzle heater 8 is activated.

Also, as shown in FIG. 4(b), the driver of the vehicle 1 presses the respective switches 36, 37, 38, and 39 instead of the switch 35 for full automatic operation, as in the case of full automatic operation. Also, it is possible to disinfect the tire 2 .

That is, the driver sitting in the driver's seat of the vehicle 1 first presses the nozzle heater switch 39 . Then, the nozzle heater 8 operates for a preset set time to heat the injection nozzle 6 and clear the blockage of ice. After that, the driver pushes the antiseptic solution switch 36 for a desired time.

Then, the injection nozzle 6 injects the disinfectant to the tire 2 only while the disinfectant switch 36 is being pushed. In other words, the spray nozzle 6 sprays the disinfectant only while the disinfectant switch 36 is pressed, and when the disinfectant switch 36 is released, the spray nozzle 6 stops spraying the disinfectant.

Next, the driver in 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, and the disinfectant in the pipe 11 and the injection nozzle 6 is discharged to the outside, and the vehicle 1 is discharged. droplets of disinfectant adhering to the

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

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

By sequentially pressing the switches 36, 37, 38 and 39 in this manner, the tires 2 of the vehicle 1 can be disinfected even during the winter in cold regions.

On the other hand, when the air temperature does not fall below freezing and there is no risk of the disinfectant freezing (summer, etc.) except in winter, as shown in FIG. The driver presses only the disinfectant switch 36 for a desired time to spray the disinfectant from the injection nozzle 6 (disinfectant is sprayed only while the disinfectant switch 36 is pressed, and the spray stops when the switch is released). , the tires 2 should be disinfected.

According to the tire disinfecting device 1, the injection nozzles 6 facing each tire 2 of the vehicle 1 can inject disinfectant, air, and antifreeze. Freezing of the liquid can be prevented, and the tires 2 of the vehicle 1 can be appropriately disinfected. Therefore, a sufficient disinfection effect can be obtained even during low-temperature drying when the activities of bacteria, viruses, etc. become active, and it is possible to appropriately prevent the infection of livestock in livestock facilities with infectious diseases.

Further, since the operation means 32 installed in the driver's seat of the vehicle 1 has at least a full automatic switch 35, a disinfectant switch 36, an air switch 37, an antifreeze switch 38 and a nozzle heater switch 39, the operability is improved. is good, and can be used appropriately in winter and summer.

Furthermore, since the nozzle heater 8 for heating the injection nozzle 6 is provided, clogging of the injection port by ice adhering to the tip of the injection nozzle 6 can be properly eliminated.

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

The tire disinfecting apparatus 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 disinfectant tank 16 and the antifreeze tank 17 . This air tank 41 is connected to the solenoid valve 22 via a connecting pipe portion 42 . When the fully automatic switch 35 is operated and 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.

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

If the vehicle (truck) 1 has an air tank (compression tank) for braking, 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 there is one pump serving as pressure-feeding means has been described.

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

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

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

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

Furthermore, the operation means 32 is, for example, an operation unit for setting the operation time of the nozzle heater 8, and each injection time (disinfectant injection time, air injection time, antifreeze injection time) in the case of full automatic setting. You may have an operation part for doing.

In addition, 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.

Furthermore, it is also possible to use the antifreeze tank 17 as a disinfectant tank, for example during the summer, for which a discharge valve 28 and a valve heater 29 are also required. If the antifreeze tank 17 is not used as a disinfectant tank, the discharge valve 28 and the valve heater 29 are not necessarily required.

Alternatively, for example, a detection means may be provided to detect clogging of the injection nozzle 6 (for example, clogging due to ice), and the nozzle heater may operate based on detection by this detection means. A configuration in which the nozzle heater 8 is operated based on this may also be adopted.
