DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a method in which a powder (particle) such as an antifreezing agent or aggregate and a liquid (solution) such as water are mounted on a traveling vehicle and sprayed on a road or the like. The present invention relates to an improvement in a wet spraying device.

[0002]

2. Description of the Related Art Conventionally, as this type of wet spraying apparatus,
For example, the one shown in FIG. 2 is known. The wet spraying apparatus 50 basically includes a rectangular tubular chute 51 for guiding the powder A downward, a supply pipe 52 for supplying the liquid B to the end of the chute 51, and a rotation near the chute 51. The rotating shaft 53 is provided so as to be able to be provided, and a spraying disk 54 is provided on the rotating shaft 53 and sprays the powder A and the liquid B discharged from the chute 51 while mixing them.

[0003]

However, in such a device, the powder and the granules and the liquid are dropped on the spraying disk and mixed by the rotation thereof to be sprayed (scattered). The body and the liquid were not completely mixed but were sprayed in an unevenly mixed state. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in order to solve the problem. The object of the present invention is to provide a wet spraying method that can uniformly mix and disperse a powder and a liquid. In providing the device.

[0004]

The wet spraying apparatus according to the present invention basically comprises a funnel-shaped chute for guiding powders downward, and a supply for supplying liquid to the chute and mixing the chute with the powders. A pipe, a rotating shaft provided rotatably through the chute, a spray disk provided on the rotating shaft for spraying a mixture of the powder and the liquid discharged from the chute around, and a spray disk provided on the rotating shaft And a discharger for forcibly discharging the mixture mixed by the chute.

The granules are guided downward by the chute, and the liquid is supplied to the chute by the supply pipe to mix the granules and the liquid. The mixture mixed by the chute is discharged from below the chute and is spread around by a spray disk. Since the chute has a funnel shape, the granular material and the liquid are gradually squeezed and discharged, and the residence time thereof is prolonged, so that the mixing time can be lengthened and uniform mixing is performed. Since the rotating shaft is provided through the chute and the discharging member is provided on the rotating shaft, the mixture mixed by the chute can be forcibly discharged, and the clogging of the mixture can be eliminated.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an outline of a wet spraying device of the present invention.

The wet spraying apparatus 1 comprises a chute 2, a supply pipe 3, a rotating shaft 4, a spraying disk 5, and a discharge body 6, and is mounted on a traveling vehicle.

The chute 2 has a funnel shape for guiding the granular material A downward. In this example, the peripheral wall 7, the side wall 8 and the rear wall 9 are provided.
And a top wall 10 and a funnel shape (conical shape) lacking a rear upper portion, an inlet 11 for supplying the granular material A to the upper front side, and a discharge port for discharging the mixture C below. Outlets 12 are respectively formed. Although not shown, the chute 2 is provided on the rear side of the vehicle body of the traveling vehicle, and has an entrance 11.
Is connected to a hopper for storing the granular material A via a metering rotor for delivering the granular material A by a predetermined amount. The hopper is provided on the vehicle body of the traveling vehicle.

The supply pipe 3 supplies the liquid B to the chute 2 and mixes the liquid B with the granular material A. In this example, the supply pipe 3 is provided so as to penetrate the upper wall 10 of the chute 2, and has a tip inside the chute 2. A tank (not shown) that stores the liquid B is connected to the base end through a pipe 13 though not shown, but via a valve or the like. The tank is
It is provided on the body of the traveling vehicle.

The chute 2 and the supply pipe 3 form a so-called mixer for mixing the granular material A and the liquid B.

The rotating shaft 4 is provided rotatably through the chute 2, and in this example, is a vertical one penetrating through the inlet 11 and the outlet 12 of the chute 2.
Although not shown, the fixed side is rotatably supported about a vertical axis via a bearing, and a rotating drive device such as a hydraulic motor or an electric motor supported on the fixed side is connected to the upper part.

The spraying disk 5 is provided on the rotating shaft 4 and sprays a mixture C of the granular material A and the liquid B discharged from the chute 2 around the disk. It comprises a boss 15 provided at the center and attached to the lower part of the rotating shaft 4, and an appropriate number of blades 16 provided radially from the boss 15 on the disk 14.

The discharging member 6 is provided on the rotating shaft 4 and forcibly discharges the mixture C mixed by the chute 2. In this example, the discharging member 6 is made of an elastic material such as rubber and has sharp edges at both ends. With a trapezoidal plate shape (spatial shape)
Attached to the rotating shaft 4 near the outlet 12 of the
The mixture C is discharged while scraping off the mixture C in or near the nearby peripheral wall 7.

Next, the operation will be described based on such a configuration. The granular material A stored in the hopper is supplied from the inlet 11 of the chute 2 by a predetermined amount by a metering rotor. The liquid B stored in the tank is supplied to the chute 2 from the supply pipe 3 via a valve or the like and the pipe 13. The powder A and the liquid B supplied to the chute 2 are mixed inside the chute 2 and discharged from the outlet 12 of the chute 2. When the rotary drive is driven, the rotating shaft 4 is rotated, and the spraying disk 5 and the discharger 6 are rotated. When the discharger 6 is rotated, the mixture C near the outlet 12 of the chute 2 is forcibly discharged. When the spreading disk 5 is rotated, the shoot 2
The mixture C discharged from and falling onto the spraying disk 5 is sprayed around.

Since the chute 2 is funnel-shaped, the powder A
And the liquid B are gradually squeezed and discharged, and the residence time thereof is prolonged, so that the mixing time can be prolonged, and uniform mixing is performed.

Since the rotating shaft 4 is provided through the chute 2 and the discharging member 6 is provided on the rotating shaft 4, the mixture C mixed by the chute 2 can be forcibly discharged from the outlet 12. Clogging of the mixture near the outlet 12 can be eliminated.

Although the discharging member 6 has a trapezoidal plate shape in the above example, the discharging member 6 is not limited to this, and may be, for example, a helical member such as a screw feeder.

As described above, according to the present invention, as described above,
The following excellent effects can be obtained. (1) Consisting of a chute, a supply pipe, a rotating shaft, a scatter disk, and a discharger. Especially, since the chute for guiding the granular material downward has a funnel shape, the residence time between the granular material and the liquid becomes longer. Thus, the mixing time can be lengthened, and the powder and the granular material can be uniformly mixed and sprayed. (2) Since the discharge member is provided on the rotating shaft provided to penetrate the chute, the mixture mixed by the chute can be forcibly discharged, and clogging of the mixture can be eliminated. (3) Since the discharging member is provided on the rotating shaft provided through the chute, the discharging member can be rotated by using the rotation of the rotating shaft, and a dedicated rotary drive is not required, which is extremely rational. It is a target.
