DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the outline | summary of the aggregate coating apparatus of a present Example is demonstrated. The aggregate coating device is configured by combining a hopper device portion, a coating tank device portion, a vibration sieve device portion, a step portion for monitoring each portion, and a remote control box portion.

The hopper device part has a hopper device that stores a certain amount of rubber aggregate to be coated, and a hopper device that is attached to the lower part of the hopper device so that the rubber aggregate can be scooped out and sent out one by one. Bei Eteiru a rotor device that multi-row arrangement the cylinder with a hole opened in one axis on the surface. In addition, the coating tank apparatus part includes an asphalt emulsion tank for coating the rubber aggregate sent out by the rotor apparatus in an asphalt emulsion as a coating solution, and the coated rubber aggregate as the asphalt emulsion storage tank. It consists of a multi-row chain conveyor as a conveying device that pulls out from the inside, and a device that sprinkles stone powder to prevent solidification of the coated rubber aggregate drawn by the chain conveyor . The vibration sieving device part receives the coated aggregate sprinkled with stone powder, and screens the aggregate and stone powder .
[0013]
Such a device is operated by power (such as a prime mover) such as electric power, and the rotation of the rotor device of the hopper device portion is varied as necessary. Further, the asphalt emulsion tank is provided with a heating device for heating the asphalt emulsion, and the conveyance speed of the multi-row chain conveyor for drawing out the coated rubber aggregate can be arbitrarily changed. ing. Therefore, the coating time of the rubber aggregate dropped from the hopper device portion into the asphalt emulsion tank can be arbitrarily selected.
[0014]
Further, the vibration sieve device part is installed at an appropriate angle, and a thin iron plate is stretched on the upper side of the bottom of the sieve device so that the stone powder does not fall. Moreover, the net | network for isolate | separating a stone powder and rubber | gum aggregate is stretched under the bottom part of the sieve apparatus . And in order to isolate | separate a rubber aggregate and stone powder, the rotation direction of a vibration sieve apparatus is reversed. Therefore, the light stone powder accumulates on the upper side of the sieve and the heavy rubber aggregate is discharged from the lower side of the sieve by the weight ratio of the material to be sieved and the appropriate sieve angle described above.
[0015]
The hopper device part, coating tank device part, vibration sieve device part, and step part are separated and independent from each other, which is advantageous for transportation, etc. Thus, the arrangement can be freely considered. The control of the hopper device part, the coating tank device part, the vibration sieve device part, and the step part can be remotely operated by a remote operation box.
[0016]
Next, the detail of the aggregate coating apparatus of a present Example is demonstrated based on FIGS. In these drawings, A is a hopper device part, B is a coating tank device part, C is a vibration sieve device part, and D is a remote control box part.
[0017]
The hopper device portion A includes a hopper device 1 for storing rubber aggregates, a rotor device 2 in which multiple rings arranged to scoop up the rubber aggregates one by one are arranged, and the rotor device 2 is driven. These are connected to each other by a chain (not shown) via a sprocket 4.

[0019]
The speed of the chain conveyor device 7 is transmitted via the chain 9 from an electric motor 8 which can be controlled by arbitrarily adjusting the coating time. Then, the coated and aggregated rubber aggregate is dropped onto the vibration sieve device portion C via the chute port 10. The chute 10 is equipped with a stone powder spraying device 11 for the purpose of preventing the coated rubber aggregate from solidifying. A heating device 12 is provided at the lower part of the asphalt emulsion tank 6, and a partition plate 13 (to prevent the rubber aggregates drawn from the hopper device part A from contacting each other) is provided at the upper part, respectively. 7 is mounted on both sides.
[0020]
The vibration sieve device portion C is provided with a sieve device 14 for separating the stone powder and the rubber aggregate installed on the mounts 15a and 15b at a predetermined appropriate angle. The angle of the sieve can be arbitrarily adjusted by changing the lengths of the mounts 15a and 15b.
[0021]
A vibration device 16 having an eccentric shaft and an unbalanced weight is attached to the sieving device 14, and power is transmitted via a belt 18 by an electric motor 17 that can arbitrarily change the rotational speed. Further, an iron plate 19 is stretched on the upper side of the bottom of the sieving device 14, and a net 20 is stretched on the lower side of the bottom so that the rubber aggregate does not fall out.
[0022]
In such a sieving device 14, the electric motor 17 is reversely rotated to apply vibration, so that the stone powder having a low specific gravity is collected in the iron plate portion 19, and the rubber aggregate having a high specific gravity is dropped to the collection box through the net 20. The In this case, the angle of the sieve device 14 is an important factor. The sieve device 14 is installed on the gantry 15a, 15b via a coil spring 21 for absorbing vibration.
[0023]
Furthermore, the operation of the power of the hopper device part A, the coating tank device part B, and the vibration sieve device part C can be easily remotely operated from the remote operation box part D.

And a width adjusting ring 24.
[0025]
The ring component 23 and the width adjustment ring 24 are alternately mounted on the shaft component 22, and a plurality of fixing holes 25 are formed in each ring component 23 and the width adjustment ring 24.

Further, partition plates 13 are provided on both sides of the transport chain device 27 so that the rubber aggregates do not contact each other. A bearing device 30 is attached to both sides of the drive shaft 26 to support it on the gantry 15a, 15b.
[0028]
According to the aggregate coating apparatus having such a configuration, the following operations and effects can be achieved. In other words, the coated rubber aggregate becomes solidified when stored for a long period of time, so it is necessary to manufacture it immediately before use, but this aggregate coating device is transported close to the construction site and easily assembled. the precoat rubber aggregate coated by bitumen emulsion can be prepared shortly before use. For this reason, since the precoat rubber aggregate whose quality is always stable can be used, it is securely held in a state where it is embedded in the pavement, and there is no problem of peeling and scattering later. Therefore, as a result, it is possible to maintain the road surface freezing prevention suppressing effect for a long time.
