Has been joined. At the junction, the chutes 11a, b and the chutes 8 are in communication with each other, and the granular spray conveyed by the conveying screw 4 falls on the chutes 11a, b or the chute 8 in the center. In the rut-spraying device 10 of the present embodiment, a sprinkling switching plate 12a, b as shown in FIG. 2 is provided at the confluence of a pair of left and right rut-spraying chutes 11a, b and the chute 8. The left and right spray switching plates 12a and 12b are connected and supported by a link mechanism 19 as shown in FIG. 3, and are rotated by the spray method switching lever 13 to the positions shown by solid lines and the alternate long and short dash lines in FIGS. I do. When the spray switching plates 12a and 12b are at the positions shown by solid lines, the spraying agent is guided to the left and right rut chutes 11a and 11b as shown by black arrows in FIG. When the spray switching plates 12a and 12b are at the positions indicated by the alternate long and short dash lines, the spray agent is guided to the central chute 8 as indicated by the white arrow in FIG.

On the other hand, the pipe 5 for guiding the aqueous solution in the tank 2 to the spraying section (FIG. 5) is divided into two parts on the way, and as shown in FIG. (Piping) 14. An aqueous solution switching valve 16 is provided at a branch portion between the disk pipe section 5a and the rut pipe section 14. By switching the switching valve 16, the aqueous solution in the tank 2 is guided to the disk piping section 5a or the rutted piping section 14.

A pair of left and right rutting hoses 15a and 15b are further connected to the rutting piping section 14. Liquid ejection pipes 17a and 17b are attached to the tips of the left and right rut hoses 15a and 15b, respectively. An appropriate number of holes (liquid ejection holes) are formed in the liquid ejection tubes 17a and 17b, and an aqueous solution is ejected from the liquid ejection holes. The liquid ejection pipes 17a and 17b are the right and left rutted chutes 11
The aqueous solutions ejected from the liquid ejecting pipes 17a, b are provided so as to protrude into left and right chute tip caps 18, 18 attached to the tips of a, b.
a and b are sprayed together with the falling granular spray.

Left and right chute tip caps 18, 18
Is a rutted chute 1 rotatable about a fulcrum 20.
1a, 1b. The angle of the cap 18 can be adjusted by loosening the stopper 21 provided slightly below the fulcrum 20. Then, the stopper 21 is tightened at a predetermined position to fix the cap 18. Branch piping 1
In the present embodiment, flexible pair of rutting hoses 15a and 15b are connected as a pair of parallel spraying pipes connected to the pipe 4. For this reason, when adjusting the angle of the cap 18, the rutted hoses 15a and 15b do not bend and do not hinder the adjustment of the cap angle. By adjusting the angle of the cap 18, it is possible to adjust the spray width at the time of rut spraying.

In this embodiment, both the spraying method switching lever 13 and the aqueous solution switching valve 16 are configured to be manually switched, but are configured to be automatically switched using an actuator such as a hydraulic cylinder. You can also. In that case, it is convenient to be configured to be able to switch from the driver's seat of the vehicle equipped with the spraying device.

The operation of spraying the antifreeze by the sprayer equipped with the rut sprayer 10 of this embodiment will be described with reference to FIG. FIG. 4 (a) shows a case in which the same disk spraying as in the prior art is performed. The spraying changeover lever 13 switches the spraying changeover plates 12a and 12b to the position shown by the one-dot chain line in FIG. Switching is performed so as to be guided to the central chute 8 as shown by a white arrow in FIG. Further, the aqueous solution is switched by the aqueous solution switching valve 16 so that the aqueous solution is guided from the chute 8 to the spraying disk 6. By operating the spraying vehicle 100 in this state, the antifreezing agent mixed with the granular spraying agent and the aqueous solution is sprayed by the spraying disk 6, and FIG.
As shown by hatching in (a), the antifreeze spreads in a fan shape, and the deicing agent is spread over a wide area on the road surface. In the case of normal disk spraying, the spray width is about 2 to 8 m.

FIG. 4 (b) shows a case in which the rut spraying is performed. The spraying changeover lever 13 switches the spraying changeover plates 12a and 12b to the positions shown by the solid lines in FIG. Rutted chute 11 as shown by the black arrow in 2
Switching is performed so as to be guided to a and b. Further, the aqueous solution switching valve 16 switches the aqueous solution so as to be guided from the rutting piping portion 14 to the rutting hoses 15a and 15b. When the spraying vehicle 100 is operated in that state, the antifreezing agent in which the granular spraying agent and the aqueous solution are mixed is removed.
As shown by hatching in FIG. 4 (b), it is scattered from the lower end openings of 1a and 1b, and is scattered in two parallel lines (referred to as rut scatter). Is sprayed with a deicing agent. In the present embodiment, the spraying range is 40 to 50 cm per rut. The spray width (the interval between the left and right spray ranges and the spray range) at the time of rut spraying is adjusted by changing the mounting angle of the chute tip caps 18.

In the present embodiment, it is also possible to carry out dry spraying without spraying an aqueous solution in both disk spraying and rut spraying. By the way, when the spraying is performed with the same amount of the antifreezing agent (granular spraying agent / aqueous solution) per unit time set as shown in FIG. 4, the disk spraying has a wider spraying range (how the agent spreads) as shown in FIG. Is large), the spray density is low. That is, the distribution density of the rutted distribution is higher. Therefore, when the spraying density is the same, the spraying by the rutted spraying can perform the spraying for a longer distance with the same amount of the antifreezing agent.

As a method of extending the spraying distance, the consumption of the antifreeze per unit time is set to be the same and the spraying vehicle 10
There is a method of increasing the operating speed of 0 (referred to as high-speed spraying) and a method of spraying while setting the operating speed of the spraying vehicle 100 to be the same and reducing the consumption of the deicing agent per unit time (referred to as low-speed spraying). Alternatively, both antifreeze consumption and operating speed can be varied. Whichever method is used, the same amount of deicing agent can be used for rut-spraying over a longer distance than disk spraying. In addition, when the rut-spraying is performed at a higher speed, the sprinkling time can be reduced because the speed is high.

As described above, the rut spraying device according to the present embodiment can be easily attached to the conventional spraying device by a minimum necessary modification, and can be easily spread in addition to the conventional disk spraying (normal spraying). It can be performed. Therefore, it is possible to select an appropriate spraying method as required, such as road surface conditions and traffic volume, to spray the antifreeze. Then, by performing the rut spraying, it is possible to perform the spraying for a longer distance with the same amount of the antifreezing agent as the conventional disk spraying, and it is possible to reduce the cost of the spraying. In addition, by providing the scatter width at the time of rut scatter application so as to be adjustable, more appropriate scatter can be performed. Further, in the case of rut spraying, a spraying method such as high-speed spraying and low-speed spraying can be selected, and spraying can be performed according to a situation such as a road surface condition or traffic volume.

The present invention is not limited to this embodiment. For example, the spraying device to which the present rutted portion spraying device is mounted may be different from the configuration shown in FIG. A book configuration may be used. Instead of a screw conveyor, a belt conveyor system may be used. Alternatively, a structure without an aqueous solution tank may be used.

In the rut-spraying device, a butterfly valve type can be used instead of the switching plates 12a and 12b for the switching method for switching between the disk spraying and the rut spraying. In addition, an appropriate configuration can be adopted for a configuration for adjusting the spray width at the time of rut spraying. Further, it is also possible to spray a spraying agent other than the antifreezing agent, for example, a non-slip agent.

[0026]

As described above, according to the rutted portion spraying device of the present invention, it is possible to easily attach the device to the conventional spraying device and perform the rutted spraying. Spray longer distances with antifreeze,
Spreading costs can be reduced. In addition, since it is possible to switch between disc spraying and rut spraying, it is possible to perform spraying according to the situation such as road surface conditions and traffic volume.

According to the second aspect of the present invention, rut spraying can be performed even in wet spraying, and spraying can be performed over a longer distance with the same amount of aqueous solution as in the related art. In addition, it is possible to switch between disk spraying and rut spraying.

According to the configuration of the third aspect, automatic switching between the disk spraying and the rut spraying becomes possible, and the labor can be saved. Also, the danger caused by switching on the road can be avoided.

According to the configuration of claim 4, since the spray width at the time of rut spraying can be adjusted, appropriate spraying according to the situation becomes possible.
