[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an asphalt material treating apparatus for melting a solid asphalt material so that the asphalt pavement material can be peeled off and the construction site can be temporarily repaired by using this material again. It is a thing.

[0002]

BACKGROUND OF THE INVENTION Under the paved road surface, water and sewer pipes, gas,
When installing electric facilities, etc., a part of the asphalt pavement is peeled off, a predetermined grooving work is performed, and after the completion, the asphalt pavement is repaved as a temporary repair. In the case of such work, the peeled solid asphalt material is usually melted again and reused as a repair material.

In most of the operations for melting the solid asphalt material, the solid asphalt material is put into a melting drum installed on a loading platform such as a truck and a flame such as a gas burner is blown to melt the solid asphalt material. In such work, as a matter of course, the solid asphalt material that has been peeled off is put into the drum, and further the heating work and the work of taking out the melted asphalt material are carried out in sequence. It was configured so that while rotating in the up and down axial directions, the whole can be tilted.

However, even if such a mechanism is provided, in consideration of the fact that many devices of this type are installed and used on the bed of a truck, for example, a drum is used for taking out molten asphalt material. The workability is not always good simply by tilting the, and further improvement is required. Furthermore, if the solid asphalt material lumps separated from the pavement surface are too large, they do not enter the melting drum, and it is necessary to divide them into small lumps by a separate operation before putting them in, which is a troublesome work.

Of course, a large mass of solid asphalt material may be forced into the drum for heating, but in such a case, it takes time to dissolve the mass of solid asphalt material and it is inefficient. In some cases, temporary repair work, which does not have time to spare, is hindered. That is, when solid lumps of asphalt material put into the melting drum are broken into small pieces, when they start to melt due to flame radiation from the burner, the heat accumulated by themselves acts on each other to shorten the melting time. However, if the mass of solid asphalt material is too large, heat is not exchanged with other asphalt materials that have already been melted or in the process of melting, and the heating efficiency of the burner flame is reduced because the heat is exclusively transferred to the burner flame. Of.

[0006]

[Technical Items Attempted to Develop] The present invention has been made from such a background, and the present inventor has an easy-to-use apparatus and is an asphalt capable of performing an efficient melting operation of a solid asphalt material. This is an attempt to develop a material processing device.

[0007]

[Constitution of the invention]

[Means for Achieving the Object] That is, the first invention of the apparatus for treating asphalt material according to the present application is an apparatus for heating and melting a solid asphalt material charged therein by a burner while rotating a melting drum. The melting drum is characterized by being supported so as to be tiltable with respect to the frame and substantially movable in the front direction on the take-out side.

The second invention of the asphalt material treating apparatus according to the present application is characterized in that, in addition to the above-mentioned requirements, the apparatus is provided with a crusher for a lump of solid asphalt material.

Furthermore, the third invention of the apparatus for treating asphalt material according to the present application is characterized in that, in addition to the above requirements, the crusher is provided above the melting drum.

Furthermore, a fourth invention of the asphalt material treating apparatus according to the present application is as follows:
In the apparatus for heating and melting the solid asphalt material charged therein by a burner, a crusher for a lump of the solid asphalt material is provided above the melting drum.

Furthermore, in addition to the above requirements, the crusher according to the fifth aspect of the present invention of the asphalt material treating apparatus is provided above the crushing drum, and the crusher is relatively provided on the discharge side of the melted asphalt material. It is characterized by being configured to be able to move out in the opposite direction. The above objects are intended to be achieved by these inventions.

[0012]

The solid asphalt material to be treated is first introduced into the melting drum. After that, the flame of the burner is emitted from the upper opening side of the melting drum while rotating, and the solid asphalt material is heated. At this time, when the melting drum is slightly inclined and rotated, the solid asphalt material inside is positively stirred, and the flame is evenly radiated, so that an efficient melting operation is performed. At this time, the melting drum as a whole is set in a state of being projected to the take-out side, and these operations are performed.

Further, when taking out the molten asphalt material, the molten asphalt material is discharged in a state of being sufficiently extended from the entire apparatus by tilting the melting drum so that the upper opening of the drum is directed downward with the molten drum being most extended to the ejection side.
Therefore, even if this work is carried out in an on-vehicle state, it is easy to receive it by an asphalt bucket or the like below the loading platform surface of the vehicle without any obstacle.

Further, in the case where a crusher is additionally provided, if the solid asphalt material peeled from the pavement surface is put into the crusher regardless of its size,
Here, the large lumps are crushed into small lumps and then put into a melting drum.

Of course, burner 25
The support itself may be fixedly provided by extending an appropriate support member from the asphalt material treating apparatus 1, or an operator may manually operate the burner 25 by hand.

In consideration of safety during work of the asphalt material processing equipment or protection when it is not used, a door 26 having a double door structure is provided on the side of the frame 2 from which the asphalt material A is taken out. A panel plate 27 or the like is attached to the portion to take safety measures so that the internal mechanism is not exposed.

Next, the crushing unit 4 will be described. The crushing unit 4 is substantially constituted by a crusher 30, which is, for example, a funnel-shaped hopper 31 provided above the frame 2 and integrally formed below the crushing chamber 32. Is used as a casing member, and a crushing rotor 33 is provided therein. The rotor 33 has a large number of crushing blades 34 around it. And the rotor 33 is a one that is driven to rotate by the crusher motor M _2, the chain 37 is wound between the driven sprocket 36 provided on the shaft end of the output sprocket 35 and the rotor 33 in the crusher motor M ₂ Then, the rotation of the crusher motor M ₂ is transmitted to the rotor 33. Reference numeral S ₂ is a tension sprocket of the chain 37.

Further, the crusher 30 has the above-mentioned melting portion 3
The lid 38 is provided on the upper part for the same safety consideration as in the above. The crusher motor M _{2 and the} like are covered by the panel plate 39. Furthermore, in order to control these devices, a control panel 40 is provided near the crusher motor M ₂ as an example. Reference numeral 41 is a motor-driven hydraulic unit from which hydraulic oil is supplied to the shift cylinder 15 and the shift cylinder 18.

The concrete structure of the apparatus for treating asphalt material according to the present invention is as described above, and operates as follows. i) Storage state The storage state before or after use is a state in which the melting drum 10 is stored in the deepest part in the frame 2 as shown by the solid line in FIG. The position may be provided at any position, but for example, the upper opening 10a is set obliquely upward as shown by the solid line in FIG. 3 or laterally as shown in FIGS. This operation is performed when the shift cylinder 15 is completely contracted, and the rotation position is set by expanding and contracting the shift cylinder 18. Further, the door 26 or the lid 38 is in a state in which its opening is closed.

Ii) Input of asphalt material In processing the asphalt material A in such a state at the construction site, the lid 38 of the crusher 30 is used.
And the crusher motor M ₂ is driven to rotate the rotor 33 of the crusher 30. The rotation speed is, for example, about 20 rotations per minute, but an appropriate rotation speed can be selected depending on the material to be crushed or the purpose. On the other hand, at this time, the melting drum 10 receives the small lumps of the solid asphalt material A crushed by the crusher 30 at the deepest position as shown by the solid line in FIG.
Set a so that it faces the most upward. In this state, the upper opening 10a of the melting drum 10 faces below the crushing chamber 32 in the crusher 30 and the lump of the solid asphalt material A falling from the upper opening 10a can be received in the melting drum 10. is there. When an appropriate amount of the solid asphalt material A is put into the melting drum 10 in such a state, the next melting operation is started.

Iii) Melting work In this state, the shift cylinder 15 is extended to move the movable bracket 13 to the take-out side of the melting drum 10, and the shift cylinder 18 is further contracted to some extent, so that the inside of the melting drum 10 is retracted. Even when the solid asphalt material A is melted, it is inclined to such an extent that it does not overflow from the upper opening. That is, the solid asphalt material A is frequently agitated in the melting drum 10 by inclining to such a state as shown in FIG. 8, and the burner 25 has a large flame action area. This is preferable in that the heat generated here does not adversely affect the various mechanisms of the crushing section 4 provided immediately above.

Iv) Removal of Molten Asphalt Material The asphalt material A which has been sufficiently melted by heating for a certain period of time in this way is taken out of the melting drum 10 for temporary repair work at a construction site. By the way, asphalt material A
Naturally, in addition to the pure tar component, it also contains stones, sand, etc. as strength members, but of course, these are also melted in the state of containing. Such molten asphalt material A
When taking out, the melting drum 10 is further tilted, and the molten asphalt material A is poured out from the upper opening 10a and transferred to a bucket or the like below it. At this time, in the present invention, since the entire melting drum 10 is largely projected to the take-out side, even if the present apparatus 1 is mounted on, for example, the loading platform of the truck T, the outlet port is sufficiently out of the loading platform. It is set in a position that projects to the outside, making it easy to pour out. Of course, as the melting asphalt material A in the melting drum 10 gradually decreases, the inclination of the melting drum 10 increases, and further, the upper opening 10a of the melting drum 10 extends obliquely downward as shown by the phantom line in FIG. Tilt to the end and perform the final removal.

The asphalt material treating apparatus 1 of the present invention has the specific construction as described above, but the basic features described in claims 1 to 3 are that the melting drum 10 moves to the take-out side. It has a flexible structure, and more preferably has a crusher 30 attached thereto. Therefore, for the crusher 30 itself, for example, a device specialized for crushing is separately provided, and from there, the melting drum 1 is provided by a conveyor or the like.
The asphalt material A crushed to 0 may be moved and charged. Further, when the crusher 30 is provided integrally with the apparatus, it is not always necessary to provide the crusher 30 above the frame 2, that is, above the melting drum 10. 30 can be installed.

When attention is paid to the crusher 30, by combining this with the melting drum 10, an excellent function exceeding that of the conventional apparatus can be obtained. Accordingly, as the melting drum 10 itself, as defined in claim 4, a structure having an appropriate structure such as only tiltable movement is applied, and the crusher 30 is provided in the vicinity (upper, side, etc.) thereof. May be. Further, in that case, as defined in claim 5, the crusher 30 is provided above the melting drum 10 and the crusher 30 can be retracted relative to the melting drum 10 in a direction opposite to the take-out direction of the molten asphalt material A. It is also possible.

[0032]
