Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a dispensing and charging device for charging asphalt mixture kneaded by a mixer in an asphalt plant into a plurality of hot mix silos provided under the mixer. .

[Conventional technology]

A device that uses a chute and a plurality of hot mix silos that are arranged in a straight line using a linear reciprocating trolley device as a device that distributes and mixes the asphalt mixture mixed in a mixer into multiple hot mix silos. It is known to put asphalt mixture into.

[Problems to be solved by the device]

The former chute type is liable to cause separation of the asphalt mixture at the time of charging the asphalt mixture, and since the chute must be inclined at a considerably steep angle, the mixer and the measuring tank related to this mixer, There is a problem that the installation positions of hot bottles, screens, etc. are all high.

In the latter case, when the asphalt mixture is put into the hot mix silo at the end of the multiple hot mix silos arranged in a straight line, the trolley is reciprocated over several hot mix silos. However, there is a problem in that it takes time to put in the asphalt mixture.

The present invention provides an asphalt mixture distribution / introduction device that can efficiently and quickly put the asphalt mixture into the hot mix silo without separating it, and does not require raising the installation position of a mixer or the like. The purpose is to

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a swing ring rail between a mixer and a plurality of hot mix silos arranged in an annular shape, the center of which is located directly below the mixer, and A trolley rail which is installed substantially horizontally so as to surround the inlet of the hot mix silo, and which is swung along the turning ring rail by the turning drive device is provided at the diameter position of the turning ring rail, and the trolley rail receives the trolley rail from the mixer. The asphalt mixture is moved along the trolley rail and provided with a trolley hopper for feeding the hot mix silo from an input port.

[Action]

In order to put the asphalt mixture mixed in the mixer into the hot mix silo, first, the trolley hopper is moved along the trolley rail just below the mixer. Then, the asphalt mixture is put into the trolley hopper from the mixer, and the trolley rail is swung along the swiveling ring rail by the operation of the swiveling drive device to move the trolley rail onto the desired hot mix silo. Then, the trolley hopper is moved along the trolley rail and placed right above the charging port of the hot mix silo, and the asphalt mixture is charged into the hot mixing silo through the charging port.

To put the asphalt mix into another hot mix silo, place the trolley hopper directly under the mixer and operate as above, or swivel the trolley rail along the swivel ring rail to position the next hot mix silo. Move the trolley hopper along the trolley rail while moving it to place it just below the mixer. If you move the trolley hopper while rotating the trolley rail and put it under the mixer, put the asphalt mixture from the mixer into the trolley hopper, without turning the trolley rail,
It goes without saying that the trolley hopper is immediately moved to the next hot mix silo. The order and operation of turning the trolley rail and moving the trolley hopper are not limited to the above.

In this way, the trolley hopper can be moved over the desired hot mix silo with the shortest distance movement, and the process of putting the asphalt mixture into the trolley hopper from the mixer and the process of turning the trolley rail with respect to the turning ring rail. Alternatively, the step of moving the trolley hopper below the mixer and the step of moving the trolley rail to the next hot mix silo can be performed in parallel, so that the asphalt mixture injection work can be performed efficiently and quickly. . Moreover, since the asphalt mixture is dropped directly into each hot mix silo, the asphalt mixture is not separated. Moreover, since the trolley hopper is used for direct charging, unlike the case where a chute is used, it is not necessary to increase the height of the mixer, the screen, the hot bottle, and the like.

The swiveling ring rail 1 has swiveling rollers 6, 6 at both ends.
(In FIG. 3, the turning roller on the rear side is the turning roller 6 on the front side.
And a trolley rail 8 with side rollers 7. The trolley rail 8 is installed at the diameter position of the turning ring rail 1 so that the turning roller 6 is brought into contact with the upper surface of the turning ring rail 1 and the side roller 7 is brought into contact with the inner peripheral surface of the turning ring rail 1, The supporting member 9 is mounted on the direct hopper 5 through a thrust bearing 10. Therefore, the trolley rail 8 can be turned around the support member 9 along the turning ring rail 1 to any position.
At least one of the turning rollers 6 has a turning drive device 11 mounted on the trolley rail 8 for at least one turning roller 6.
Are connected via a transmission mechanism 12 such as a chain.

Further, reference numeral 13 is a trolley hopper. This trolley hopper 13
Is mounted on the trolley rail 8 having a channel structure so as to be movable along the trolley rail 8. The trolley hopper 13 has this trolley rail 8
A drive device for moving along is attached, but it is omitted in the drawing. As the moving drive device, the turning drive device 11 for rotating the turning roller 6 is used.
Similarly to the above, the wheel 14 is generally rotated, but the trolley hopper 13 may be pulled by a wire or the like, and its specific structure is arbitrary. The bottom portion 13a of the trolley hopper 13 can be opened and closed.
