FIG. 4 is a simplified diagram of a second embodiment according to the present invention, FIG. 5 is a simplified diagram of the third embodiment,
It is.

First, reference numeral 1 shown in FIGS. 1 to 5 indicates a tank having a capacity of 1 t for storing a disinfectant 4 (described later).
It has an inlet 101 that opens upward, and an outlet 102 that can open and close below.

The main body of the tank 1 is formed by FRP so that rust and corrosion do not occur, and the inside of the tank 1 is subjected to a corrosion-resistant treatment against a strongly acidic disinfectant 4.

The capacity of the tank 1 is not limited to 1 ton, but can be appropriately selected in consideration of the capacity of the feed storage room of the feed transport vehicle, the feed unloading speed, and the like. Further, a transparent see-through window may be provided in a part of the side surface of the tank 1 in the vertical direction so that the state of the sterilizing agent 4 stored inside can be monitored.

Here, the tank 1 used in the first embodiment
Is fixed and installed at a position above the gantry 2a, as shown in FIGS. The gantry 2a is formed in a four-legged frame formed of a steel frame or the like coated with hot-dip galvanization, and has an open space large enough for the feed truck 3 to pass inside. .

When the feed truck 3 enters the tank 2a and stops when the feed truck 3 is stopped, the outlet 102 of the tank 1 is provided at the rear of the feed truck 3;
It is installed on the gantry 2a so as to have a height slightly above the feed inlet 10 formed on the upper surface of the feed tank 7 having the feed storage room 5 (5a to 5d) (see FIG. 3) therein. I have.

In the first embodiment, the gantry 2a
Since the sterilization operation is performed in a state in which the feed transport vehicle 3 is entered and stopped in the interior, a site having a width equal to the width of the gantry 2a is sufficient, and a space-saving sterilization method that does not take a width. Or a device.

Hereinafter, the structure of the feed carrier indicated by reference numeral 3 will be described with reference to FIG. The feed transport vehicle 3 is provided with a feed tank 7 at a rear portion thereof, and the inside of the feed tank 7 is partitioned into a plurality of feed storage rooms 5 (5a to 5d). Further, above the feed storage room 5 (5a to 5d), that is,
On the upper surface of the feed tank 7, each feed storage room 5 (5a-5
A feed inlet 10 corresponding to d) is formed.

On the other hand, below the feed storage room 5 (5a to 5d), a feed conveying screw (bottom screw) 9a is provided.
The feed is extended from the front to the rear of the vehicle, and is designed so that a necessary kind of feed can be appropriately selected and sent to the outside by rotating the feed feed screw 9a.

That is, the feed fed from the front to the rear of the vehicle by the bottom screw 9a is fed to a feed feeding screw (vertical screw) 9b erected at the rear of the vehicle.
Then, it is transported by a feed transport screw (discharge screw) 9c connected to the upper end of the vertical screw 9b and extending above the vehicle body. Then, the transported feed is discharged to the outside (for example, a storage tank, a feed yard, or the like) from a discharge port 11 formed at a distal end portion of the discharge unit 8.

As described above, the feed transport vehicle 3 is designed to store, transport and transport a plurality of feeds, and is very convenient, but on the other hand, its structure is complicated and closed. In particular, the transport screw 9
The portions (9a to 9c) have a problem that they are difficult to wash or the like and are easily contaminated by bacteria.

Further, since the feed transport vehicle 3 can store a plurality of feeds at the same time, if a harmful bacterium such as Salmonella is mixed in a certain feed, the feed screw 9 (which becomes a common feed path for all feeds). There may also be a problem that bacteria are easily transmitted to other feeds via the 9a-9c) portions.

Therefore, effective measures for sterilization of the feed transport vehicle 3 are required, but it is necessary to avoid spending a lot of time on the sterilization operation due to the demand for improving the feed transport efficiency. Accordingly, there is a need for a method and apparatus that can perform frequent sterilization operations in a quick and simple manner.

Hereinafter, the sterilization process of the feed truck 3 according to the first embodiment will be specifically described with reference to FIG. First,
Feed storage room 5a of the feed transport vehicle 3 stopped in the gantry 2a
5c stores different types of feeds 6a to 6c, respectively.

On the other hand, the feed storage room 5d closest to the driver's seat side
Only the feed is not stored, and the disinfectant 4 may be charged, and the feed carrier 3 is moved so that the outlet 102 of the tank 1 faces the feed inlet 10 above the feed storage room 5d. Stop.

Next, by opening a slide-type opening / closing plate 103 provided at the lower end of the discharge port 102, the sterilizer 4 stored in advance is supplied from the tank 1 to the feed storage room 5d.
To The reason that the feed storage room 5d is selected and the disinfectant 4 is supplied is to disinfect the entire bottom screw 9a extending in front and rear of the vehicle body.

The bactericide 4 used here is a strongly acidic powder, specifically, formic acid 70%, propionic acid 2
Consists of 0% and 10% moisture components. Therefore, the outlet 10
2 and a slide-type opening / closing plate 1 provided in the outlet 102
03 needs to be formed from a corrosion-resistant stainless steel or the like.

Incidentally, the slide type opening / closing plate 103 is not limited to the slide type, and can be selected as appropriate. Further, the bactericide 4 is not limited to the above components, but can be appropriately selected according to the type of bacteria and the like. However, the feed transport screw (vertical screw) 9b has a problem that it is difficult to raise the liquid, and if the transport screw 9 is wet, a problem that the feed hardens or rots may occur. Use agent.

Next, the disinfectant 4 injected into the feed storage room 5d is formed at the bottom of the feed storage room 5d while sterilizing the feed storage room 5d itself, and is discharged to the lower conveying screw 9a. From an outlet (not shown), it is fed into the rotating transport screw 9a. In this case, the other feed storage rooms 5a to 5c containing the feed are not opened with respect to the transport screw 9a.

The germicide 4 sequentially fed to the conveying screw 9a is conveyed to the rear of the vehicle by the bottom screw 9a and rises by the vertical screw 9b. Further, it is conveyed by the discharge screw 9c, and is again discharged from the discharge port 11 (not shown in FIG. 3) to the tank 1
(See FIGS. 1 and 2). That is, in this transport step, the germicide 4 sterilizes the transport screws 9 (9a to 9c).

The disinfectant 4 returned to the tank 1
After being stored again and reused multiple times, it is replaced as appropriate. In addition, it is desirable to perform the above-mentioned sterilization work periodically, about two or three times a month in consideration of the work efficiency of feed transportation.

Here, the time required for one sterilization operation is, for example, when about 500 kg of the sterilizing agent 4 is used, the sterilization can be performed by the feed transport vehicle 3 having a feed transportation capacity of 500 kg per minute. The disinfecting operation can be performed in an extremely short time, which is about one minute from the start of the introduction of the agent 4 into the transport screw 9. If the germicide 4 is continuously circulated, a more sufficient germicidal effect can be obtained.

Hereinafter, a second embodiment according to the present invention will be described with reference to FIG. The tank 1 is fixed above an elevated stand 2b formed of a steel frame or the like plated with hot-dip galvanizing.

A sterilizer 4 previously stored in a tank 1 is formed of a corrosion-resistant material such as a stainless steel material into a feed storage room 5 of a feed transport vehicle 3 stopped beside the elevated platform 2b. Through the shooter 104 connected to the discharge port 102, it is dropped naturally and thrown.

The mounting angle of the shooter 104 is
Approximately 30 to allow the powder to slide smoothly
High strength is desirable. Further, an opening / closing plate 105 similarly formed of a stainless steel material or the like may be provided at a tip portion on the side of the inlet 10.

Next, as in the first embodiment, the feed disinfectant 4 is conveyed by rotating the feed conveying screw 9 (omitted in FIG. 4), and the disinfectant 4 is returned to the tank 1 again. The feed storage room 5 and the feed conveying screw 9 are sterilized.

Hereinafter, a third embodiment according to the present invention will be described with reference to FIG. A gantry 2c having a relatively low height, which is formed of a hot-dip galvanized steel frame or the like, a tank 1 installed on the gantry 2c and storing the disinfectant 4, and an outlet 102 of the tank. And a transport device 12 internally provided with a screw 13 for feeding the disinfectant 4 into the feed storage room 5 of the transport vehicle 3.

A feature of the present embodiment is that the disinfectant 4 is forcibly introduced into the feed storage room 5 from the tank 1 disposed at a low position via the transfer device 12. Since a specific sterilization method is the same as in the first and second embodiments, the description thereof is omitted.

In this embodiment, since the tank is installed at a low place, replacement of the germicide 4 and maintenance of the tank 1 are facilitated. In this embodiment, a simple hopper may be used instead of the tank 1.

In the above-described embodiment of the method and apparatus for sterilizing a feed carrier according to the present invention, the sterilizing agent 4 is supplied to the feed storage room 5 depending on the area and shape of the site and the location of other buildings. There may be a case where the step of charging and the step of returning the germicide 4 conveyed to the tank 1 cannot be performed simultaneously in one place.

In this case, first, the disinfectant 4 is put into the feed storage room 5 and temporarily stored therein, and then the feed carrier 3 is placed above the tank 1 at the discharge port 1 of the discharge screw 9c.
1 is moved to a place where it can face, and the disinfectant 4 is transported,
What is necessary is just to return the disinfectant 4 to the tank 1.
