Description

  The present invention relates to an antifreezing agent spraying device capable of spraying an antifreezing agent on the road surface of an oncoming lane or an overtaking lane, or on a ridge of a road surface of a traveling lane.

  Conventionally, in winter, in order to prevent freezing of the road surface, the antifreezing agent is sprayed on the road surface by an antifreezing agent spraying vehicle. As such an antifreezing agent spraying vehicle, the antifreezing agent is stored in a freezing agent storage hopper installed on the main body of the spraying vehicle, and the antifreezing agent of the storage hopper is conveyed by a conveyor while traveling at a predetermined speed. After transporting to the rear end of the spreader car body, it is configured to drop onto a rotating spraying disk of the spraying device through a chute and spray evenly on the surrounding road surface by the rotating centrifugal force of this disk. At this time, in order to prevent the antifreezing agent from being sprayed to the road surface portion that does not need to be sprayed by the rotation of the spraying disk, for example, as described in Patent Document 1, this is arranged on the front side of the spraying disk. A fixed scattering prevention plate that is curved in an arc shape along the outer periphery of the scattering disk is disposed to regulate the spraying angle and spraying range of the antifreezing agent.

  However, in such a configuration, the antifreezing agent can be sprayed over the entire road surface of the lane to be sprayed, but it is not necessary to spray on the road surface other than the buttock for a one-lane road. In spite of this, spraying over the entire surface is not only extremely uneconomical due to spraying more cryoprotectant than necessary, but also reduces the spraying distance and significantly reduces the efficiency of spraying work. Will do.

  For this reason, as described in Patent Document 2, a buttock spraying device has been developed that enables the antifreezing agent to be intensively sprayed on the ridges of the road surface. This buttock spraying device is provided with a pair of left and right shoots for feeding the antifreeze agent to the buttock side on both sides of the chute for feeding the antifreeze agent on the rotating disk, and the upper ends of these three chutes. A switching plate that switches the supply of the antifreeze agent to the above-mentioned chute that leads to the rotating disk and these chutes is arranged in the opening. The pipe from the aqueous solution tank is divided into two in the middle and branched into a pipe part on the disk side and a pipe part on the rolling side.

  However, according to the above-described buttocks spraying device, apart from the supply chute of the antifreezing agent on the spreading disk, it is necessary to provide a pair of left and right burning chutes. In addition to the need to install a separate antifreeze conveyor, it is also necessary to install a branch pipe that sprays the aqueous solution onto each chute as described above in order to spray wet antifreeze. As a result, the entire device becomes complicated and not only is it prone to failure, but it is also expensive, and it is difficult to improve the existing antifreezing agent spraying device so that it can be sprayed on the buttock. There was a problem.

  The present invention has been made in view of such problems, and the object of the present invention is to efficiently and reliably spray the antifreezing agent on the desired road surface and only the buttocks with a simple structure. Another object of the present invention is to provide an antifreezing agent spraying device that can be economically performed.

An engagement groove 20 is provided. In addition, in order to prevent the engagement groove 20 from being accidentally detached from the outer peripheral edge of the fixed disk 6, the tip of the upper edge that is refracted into a U-shape that forms the engagement groove 20 is bent downward. On the other hand, a protrusion is provided on the outer peripheral edge of the upper surface of the fixed disk 6, and the tip bent portion may be slidably engaged with the protrusion.

  In addition, brackets 21 and 21 are provided on the outer peripheral surfaces of the one half 8A and the other half 8B of the movable scattering prevention plate 8 ', and projecting shafts 22 and 22 projecting upward from the brackets 21 and 21. The tips of piston rods 23a and 23a of cylinders 23 and 23 mounted on the fixed support frames 12 and 12 are rotatably connected. Since other structures are the same as those in the above embodiment, detailed description thereof is omitted.
