Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a vertical asphalt recycling device that is capable of recycling asphalt pieces peeled off from a paved road surface or the like at a work site on the spot.

[Conventional technology]

Traditionally, at work sites where gas pipes, water and sewage pipes, electric and telephone cables, and other buried underground objects on paved road surfaces are repaired, temporary restoration is carried out by filling small-scale excavated road surfaces with a room-temperature mixture that hardens at room temperature. are doing. However, this room-temperature composite material has problems in terms of strength and adhesion, and fragments may be scattered during vehicle operation.
Since the restored area has settled, the room-temperature mixture will be removed at a later date and refilled with heated mixture. Therefore, it is desirable to repair the excavated road surface with heated composite material from the beginning, but heated composite material has conventionally been manufactured in asphalt recycling blunts with large equipment, and it has been difficult to carry it around each time work is carried out. There is also a dedicated device in which an asphalt regeneration plant is mounted on a vehicle, but it is still a waste of money when it comes to repairing the above-mentioned small-scale excavated road surfaces. Therefore, as a result of intensive research, the inventors of the present invention aimed to make the playback device portable and further miniaturize it.
The present invention was completed based on the knowledge that making the pot body vertical without rotating it is advantageous for downsizing.

[Problem that the invention attempts to solve]

This idea was devised in view of the above circumstances, and its main problem was to fix the pot body,
To provide a vertical asphalt regeneration device which is further simplified and downsized by providing a rotary blade therein and discharging the regenerated asphalt from a bottom discharge hole of a pot body.

[Means to solve the problem]

This invention solves the above problems by (a) providing a box-shaped housing with a lid that can be opened and closed on the top surface; (b) being fixed within the housing with an open top and a discharge hole in the bottom. (c) providing a rotary blade rotatably installed inside the pot body to agitate the contents; (d) providing an upper part of the housing; (e) A burner holder is provided on the peripheral wall of the housing so that it can be opened and closed, and when opened, the burner holder is tilted diagonally forward and the burner holder can be held with the tip of the burner facing the inside of the pot body. A technical measure has been taken to install a shooter that can direct the recycled asphalt that falls from the outlet of the main unit downward to the outside.

[Effect]

The crushed asphalt pieces are introduced into the pot through the opening of the pot body. Also, hang the burner on the burner holder and direct the burner toward the inside of the pot body. Then, the flame of the burner is radiated into the inside of the pot body, and the rotor blades are rotated to heat and melt the asphalt pieces inside the pot body while stirring. After the asphalt is regenerated, a discharge hole is opened by the opening/closing device, and the regenerated asphalt is discharged to the outside through the shooter.

【Example】

A preferred embodiment of the vertical asphalt regeneration apparatus of this invention will be described below with reference to the drawings. The vertical asphalt regeneration device 1 shown in FIG.
A hook body 2 is built in a housing 10. The pot body 2 has a cylindrical shape with an open top and a bottom, and is fixed in a box-shaped housing 10 while tilting forward. Here, an upper partition plate 13 having an input side opening 13' along the opening of the pot body is horizontally fixed to the upper part of the housing 10. In this embodiment, the burner holder 7 is attached to the upper partition plate 13. In this burner holder 7, a cylindrical receiver 7A is arranged at the center of the input side opening 13', and the base end of the rod 7B holding the receiver 7A is connected to the upper partition plate 1.

The burner 8 shown in FIG. 1 is connected to a gas cylinder 9 serving as a heat source by a flexible tube, and the tip side is a fixed U-shaped tube 10A to avoid the influence of heat from the pot body 2. In this embodiment, the burner 8 is removable, but
For example, the rod 7B of the burner holder is connected to a rotating shaft provided on the upper partition plate 13 so that it can rotate freely in the left and right directions, and when asphalt pieces are inserted, it is rotated to a position that avoids the opening on the input side, and when heated, it is rotated to a position on the input side. If a configuration is used that returns to the opening, the burner 8
may be attached to the burner holder 7 at all times. Next, above the upper partition plate 13, an upper lid 14 is folded to be able to open and close the input side opening 13'.
is provided. The upper lid 14 is constructed by two movable plates screwed together at the rear and folded back, so that an opening can be exposed as shown in the first figure when unfolded. Further, a discharge side opening 12' is provided on the front (front) side of the housing 10, and the discharge side opening 12' is supported by a shaft 15 installed horizontally on the lower front side of the housing 10 as a fulcrum. It can be opened and closed by a shutter 12 that pivots back and forth. In this embodiment, the shooter 12 is provided in the housing 10 so as to be openable and closable, but it may also be configured to be detachable and attached when dropping recycled asphalt. Also, if it is large as shown in the figure, it is easy to guide and convenient, but with this invention, the shooter only needs to be a guide for discharging recycled asphalt that has fallen from the discharge hole 2A outward from the pot body 2, and can be used as a sub-shutter as described below. 6 alone is within the technical scope of the shooter of this invention. Next, the pot body 2 built into the housing 10
A substantially semicircular discharge hole 2A is provided at the bottom of the , in this embodiment, along the front outer peripheral edge that is the lowest end.
is provided. The discharge hole 2A is provided with an opening/closing device 5 that opens and closes it from the outside. This opening/closing device 5 includes a fan-shaped closing plate 5A that covers and closes the discharge hole 2A from the outside, and a rotating shaft 5 that stands up integrally and vertically from a corner of the closing plate 5A.
A working part consisting of a handle 11 connected to the tip of the rotating shaft 5B and bent horizontally within the discharge side opening of the housing 10;
and a bearing part 5C that engages in the vertical direction and is slidable on the outer bottom surface of the pot body so that the closing plate 5A can freely open and close the discharge hole 2A. It is fixed to the outer surface of the pot body 2. When the handle 11 is closed, it is oriented horizontally along the outer peripheral surface of the hook body 2 as shown in FIG. It slides and rotates along the bottom surface of the pot to open the discharge hole 2A, and when it is closed, it rotates in the opposite direction so that the closing plate 5A covers the discharge hole 2A and closes it so as to come into close contact with the outer bottom surface of the pot body 2. . In this embodiment, a sub-shower 6 having a channel-shaped cross section is provided at a position below the discharge hole 2A. This sub-shutator 6 may be fixed to the housing 10 via a horizontally crushed material, or its base end may be fixed to the bottom of the pot body 2, in short, the discharge hole 2
It suffices if it is placed at a position where it can reliably catch the recycled asphalt falling from A. When the shutter 12 provided in the housing 10 is opened, the rear end side of the shutter 12 abuts from below and becomes a stopper, and the shutter 12 is tilted in the extending direction of the sub-shutter 6. Since both of them are deployed in series, the recycled asphalt dropped from the discharge hole 2A can be dropped in a predetermined direction. Next, a rotary blade 3 is placed in the center of the inner bottom surface of the pot body 2.
is installed. In this embodiment, the rotary blade 3 has a configuration in which three blades having different lengths and shapes are arranged radially at approximately equal intervals around the rotation axis. That is, the blades include a first blade 3A having a rectangular shape, a second blade 3B having a sharp tip having a blade portion tapered in the rotational direction, and a blade portion 3B having a short tip and having a tapered tip in the counter-rotation direction. It consists of a third blade 3C having a pointed shape. The rotary shaft of the rotary blade 3 extends downward through the hook body, and is connected to an electric motor 4 shown as an example of a rotary drive unit via a reducer 4A, and rotates when a switch S is turned on. The configuration is possible. With the above structure, when the crushed asphalt pieces are put into the pot body 2 and the burner 8 is set in the receiver tube 7A, the burner 8 will move toward the hollow inside of the pot body 2. . When the burner 8 is ignited in this state, the asphalt pieces inside the pot body 2 are heated by the flame. At the same time, a switch S provided in the housing 10
When the electric motor 4 is turned on, the electric motor 4 starts to rotate, the rotary shaft of the rotary blade 3 is rotated via the reducer 4A connected to the electric motor 4, and the stored asphalt pieces are agitated by the rotary blade 3. Furthermore, since the blades of the rotary blades 3 have different shapes, the asphalt pieces are stirred while being given irregular impacts and heated by the flame of the burner 8, so that the asphalt pieces can be heated efficiently. Then, the heated and regenerated asphalt is transferred to the closing plate 5 by pulling the handle 11 and rotating the rotating shaft 5A.
is opened and dropped into sub-shower 6. Further, the liquid is dropped through a shooter 12 provided in the housing 10 into a work site or a container for transportation. In this embodiment, a cylindrical pot with a bottom is used as the pot body 2, but the pot body 2 is not limited to this shape. Further, the position of the discharge hole may be on the lower side of the circumferential surface, and in short, any position may be sufficient as long as the contents can fall from within the pot body. The opening/closing device opens and closes the discharge hole, and may be configured to open and close by rotating the closing plate up and down, and furthermore, the opening and closing may be performed not manually but by other power. good. Further, in this case, the closing plate may also serve as a shutter or a sub-shutter when deployed.

[Effects of the invention] The asphalt vertical regeneration device of this invention has the following features: the pot body is fixed vertically and rotary blades are provided inside
By providing a discharge hole at the bottom of the pot body, it is possible to rotate the pot body when discharging recycled asphalt.
In addition, it is safe because there is no need to rotate the pot body itself in the circumferential direction to stir the asphalt, and the structure is simpler and more compact, which is advantageous. Since the pot body can be fixed within the housing, it can be easily transported, and since the charging lid and the discharging shutter are integrally formed in the housing, operation is further facilitated. In addition, it can be placed in a small truck or the like together with other tools for repairing underground objects in a small space. In addition, the small burner used to heat repaired road surfaces can be used as a burner for asphalt regeneration. Furthermore, since the asphalt pieces of the road surface crushed at the construction site can be recycled as they are to repair the road surface, it is extremely beneficial because the work can be done in no time.
