Sprayed materials include sand and salt and snow removal agents such as calcium chloride, liquid or solid substances that can be sprayed on the road surface, various types of agents that can be sprayed into the air, and the like.

The sprayed water supply means 10 includes an integral means for supplying at least one sprayed material of the plurality of sprayed materials to the storage tank 20.

For example, a hopper loaded with a snow removing agent or a mixer drum provided in a ready-mixed vehicle can be used.

The mixer drum is mounted on a conventional ready-mixed concrete mixer truck, is provided on one side of the body frame so as to be rotatable, and has a mixing space for storing and storing the sprayed object therein. Is built in.

The inside of the reservoir 20 is provided with a plurality of stirrers 81 for stirring the sprayed object on the stirring shaft 82 and is rotated by the stirring motor 83.

The storage tank 20 may be provided by dividing the plurality of storage spaces 21 and 22 so as to separate and store the plurality of sprayed objects independently.

As shown in FIG. 7 and FIG. 8, different types of sprayed material are accommodated in each of the storage spaces 21 and 22. For example, one storage space 21 stores calcium chloride and another storage space. Salt is stored at 22. Since the different types of sprayed material have different physical properties, it may be desirable to store them separately depending on the type of sprayed material because they may cause undesired chemical reactions before being sprayed. The sprayed objects stored in this manner are separately discharged or mixed at the bottom of the storage tank 20.

As described above, although it is possible to provide a plurality of independent storage spaces 21 and 22 inside the storage tank 20, it is also possible to separate and store the sprayed object in the sprayed object supply means 110.

That is, as shown in Figure 9, the sprayed water supply means 110 is provided with a stacking box 111 and the sprayed water transporting means 112, a plurality of storage space (111a) (111b) in the stacking box 111 It is provided. The sprayed water is introduced into the storage tank 20 through the sprayed water transporting means 112 from each of the storage spaces 111a and 111b of the loading box 111.

The storage tank 20 includes a driving lane discharge port 23 for discharging the sprayed object to the driving lane of the vehicle, a left lane discharge port 24 for discharging the sprayed object to the lane to the left of the driving lane, and a lane to the right of the driving lane. A right lane discharge port 25 for discharging the sprayed object is provided.

On one side of the reservoir 20, the driving lane opening and closing member 31 for opening and closing the driving lane outlet 23, the left lane opening and closing member 32 for opening and closing the left lane outlet 24, and the right lane outlet 25 are provided. The right and left lane opening and closing members 33 which open and close are hinged.

An actuator is provided in the driving lane opening / closing member 31, the left lane opening / closing member 32, and the right lane opening / closing member 33, respectively, so that the driving lane opening / closing member 31, the left lane opening / closing member 32, and the right lane are respectively provided. The opening and closing member 33 can be opened and closed independently of each other.

The spreading amount control unit 60 controls the operation of each actuator so as to simultaneously open and close a plurality of the driving lane discharge port 23, the left lane discharge port 24, and the right lane discharge port 25.

That is, when the sprayed object is to be sprayed on the driving lane and the left lane at the same time, the driving lane opening and closing member 31 and the left lane opening and closing member 32 are respectively opened and closed by the respective actuators to drive the driving lane outlet 23 and the left lane. The sprayed object is discharged to the outlet 24.

In addition, when the sprayed object is to be sprayed on the driving lane and the right lane at the same time, the driving lane opening and closing member 31 and the right lane opening and closing member 33 are opened and closed with respective actuators, respectively, to drive the lane exit 23 and the right lane. The sprayed object is discharged to the outlet 25.

In the case where the sprayed object is to be sprayed on both the driving lane, the right lane, and the left lane at the same time, all of the driving lane opening and closing member 31, the right lane opening and closing member 33, and the left lane opening and closing member 32 are opened. By spraying the sprayed object to the 23 and the right lane discharge port 25 and the left lane discharge port 24, it is possible to spray the sprayed object to the tram line.

In this way, the spreading amount control unit 60 is provided with a mode selection unit 61 in the driver's seat for spraying along the lane. The mode selection unit 61 includes a traveling lane selection unit 61a for spraying only on the traveling lane, a traveling / right selection unit 61b for spraying on the traveling lane and the right lane, and a traveling for spraying on the traveling lane and the left lane. The left selection part 61c and the catenary line selection part 61d are provided.

The spreading means includes a splitter 40 which is rotatably provided so that the sprayed object is sprayed by centrifugal force, and a splitter driving means 50 which axially rotates the splitter 40.

The splitter 40 includes a rotating plate 41 and a spreading blade 42 provided on the upper surface of the rotating plate 41.

The splitter 40 is provided below the discharge port of the storage tank 20 and is loaded with the sprayed object which is discharged from the discharge port and falls.

As shown in FIG. 5, a plurality of spreading blades 42 are provided at predetermined intervals along the rotational direction of the rotating plate 41, and each of the spreading blades 42 extends along the radial direction of the rotating plate 41. Formed to form a radial shape as a whole.

When the rotating plate 41 is axially rotated by the splitter driving means 50, the sprayed object is scattered by centrifugal force, and the sprayed sprayed object is guided by the spraying blade 42 and discharged in the radial direction.

On the other hand, in each spreading blade 42, the outer tip portion 42a is bent in the rotational direction. The warped outer tip portion 42a allows the sprayed object to be scattered farther than if it was not bent.

The spreading amount control unit 60 controls the operation of the actuator to adjust the spreading amount according to the running speed of the vehicle.

That is, the spraying amount control unit 60 collects the traveling speed from the traveling speed detecting unit 72 and opens and closes the opening / closing members 31, 32, 33 by an actuator to increase and decrease the opening area of the discharge port in proportion to the traveling speed. Increasing the running speed of the vehicle increases the opening area of the outlet, and conversely, decreasing the running speed decreases the opening area of the outlet.

The sprayed water supply means 10 is provided with an opening / closing valve 16 for blocking the inflow passage 15 flowing into the storage tank 20. One side of the reservoir 20 is provided with an upper limit level switch 73 and a lower limit level switch 74.

The upper limit level switch 73 closes the inflow passage 15 by operating the on / off valve 16 when the water level of the reservoir 20 reaches the set upper limit value, and the lower limit level switch 74 of the reservoir 20 When the lower limit is reached, the shutoff valve 16 is operated to open the inflow passage 15.

That is, the upper limit level switch 73 measures the upper limit of the water level of the reservoir 20 so that the reservoir 20 does not overflow, and the lower limit level switch 74 measures the lower limit of the level of the reservoir 20 to discharge. Ensure that the sprayed water released to the system is smoothly supplied.

Spreading amount measuring means 71 is a sensor for measuring the flow rate of the sprayed object discharged through the outlet of the reservoir 20, respectively provided in the driving lane outlet 23, the right lane outlet 25 and the left lane outlet 24 do.

The spreading amount control unit 60 calculates the total amount of spreading amount by adding up the respective spreading amounts measured by the three spreading amount measuring means 71 provided at each discharge port.

The spreading amount control unit 60 may control the flow rate of the sprayed water flowing into the reservoir 20 from the sprayed water supply means 10 according to the total sprayed amount measured in this way. That is, when the value measured by the spraying amount measuring means 71 is equal to or more than a predetermined value, the opening area of the inflow passage 15 is increased to increase the flow rate of the sprayed object to be supplied to the reservoir 20, and conversely, the total spray amount is small. If it is below stationary, the opening area of the inflow passage 15 is reduced.

In addition, the spreading amount control unit 60 controls the rotational speed of the splitter 40 according to the total spraying amount of the sprayed object measured by the spraying amount measuring means 71.

That is, the rotation speed of the splitter 40 is increased or decreased in direct proportion to the total spray amount of the sprayed object. When the rotational speed of the splitter 40 is increased, the centrifugal force is increased to increase the scattering distance of the sprayed object. As the spraying rate discharged from the discharge port of the reservoir 20 increases, the spraying speed of the splitter 40 is increased to scatter the sprayed material from a more adjacent place to a far place.

Even if the discharge amount of the sprayed object does not increase, if the rotational speed of the splitter 40 is not increased, the scattering distance does not increase and only the supply amount of the adjacent area increases. On the contrary, even if there is no change in the discharge amount of the sprayed object, if the rotation speed of the splitter 40 is increased, the supply amount of the sprayed object per unit area decreases even if the scattering distance increases. Therefore, it is preferable that the splitter 40 increases or decreases the rotation speed in proportion to the discharge amount from the reservoir 20.

On the other hand, the mode selector 61 includes a small amount selector 61e, a weight selector 61f, and a large quantity selector 61g for controlling the amount of spraying discharged from the outlet of the reservoir 20. When one of these selections is selected, the spraying amount control unit 60 operates the actuator to adjust the opening area of the outlet.

The actuator is provided with a solenoid valve whose operating time is adjusted according to the amount of current, and the opening area of the outlet is adjusted in multiple stages through the amount of current supplied from the spraying amount control unit 60 to the solenoid valve. When any one of the small amount selecting portion 61e, the weight selecting portion 61f and the large quantity selecting portion 61g is selected, the spreading amount control portion 60 applies the set current to the actuator to change the opening area.

In addition, the mode selection unit 61 includes an automatic selection unit 61h, and when the automatic selection unit 61h is selected, the spraying amount control unit 60 may increase or decrease the opening area of the discharge port in proportion to the running speed of the vehicle. Set the solenoid valve control value of the actuator.

That is, the spraying amount control unit 60 detects the traveling speed for each section and applies a current value corresponding to the speed for each section to the solenoid valve. For example, when the traveling speed is 30 to 40 km / h, the same current is applied as when the small amount selection section 61e is selected, and when it is 40 to 50 km / h, the same current as when the weight selection section 61f is selected. If the current is applied to 50 ~ 60 km / h, the same current as when selecting the mass selector 61g is applied.

When the running speed exceeds a predetermined speed (for example, 60 km / h), the spraying amount control unit 60 closes the discharge port to block the discharge of the sprayed object. In this case, the spraying amount control unit 60 switches the system to the driving mode by blocking the inflow passage 15 flowing into the reservoir 20 and stopping the operation of the sprayed water supply means.
