Ascon heat retainer in finisher {ASCON HEAT RETAINER IN FINISHER}

The present invention relates to an ascon heat retaining device in a finisher, and in particular, a device capable of maintaining and equalizing the heat of ascon in a hopper constituted in a finisher capable of repairing or paving an asphalt pavement (ASCON: ASphalt CONcrete) It relates to an ascon heat retaining device in a finisher that can increase the quality of asphalt pavement by constructing ascon to maintain heat during asphalt pavement and laying ascon so that the retained heat is uniformly distributed.

In general, ascon pavement cracks are caused by a number of factors, such as repeated expansion and contraction according to seasonal temperature changes, unevenness of static and dynamic loads and stresses applied by vehicles, aging and subsidence. In addition, cracks are occurring along the road surface of paved roads, and cracks are occurring due to poor compaction and poor adhesion.

One of the causes of these cracks is the lack of heat applied to the asphalt concrete at the time of asphalt concrete laying or the uneven heat of the asphalt concrete, and other causes include the addition of foreign substances and cracks after laying.

When rainwater penetrates after cracks occur, the cracks become larger and eventually lead to damage to the road, which not only interferes with vehicle traffic but also increases the risk of safety accidents.

However, this prior art describes the improvement of the quality of the asphalt pavement by heating the ascon road after paving the asphalt road, but when the finisher uniformly heats the ascon road during the primary pavement, a higher quality asphalt road is paved. Therefore, it is necessary to maintain the heat of the ascon before paving and to maintain the heat of the ascon evenly.

Referring to FIGS. 1 to 5 , first, the finisher 10 of the present invention is a heavy equipment that moves by wheels or tracks. In general, the finisher 10 moves by a track. The asphalt heat retaining device in the finisher 10 of the present invention is disposed around the combined hopper 100.

First, the finisher 10 includes a combined hopper 100, a conveyor belt 200, a transfer screw 300, a flattening unit 400, and a console 700.

First, the combined hopper 100 of the present invention is disposed on the front side of the finisher 10 and is configured to be additionally placed on the hopper of the finisher 10 in the form of a loading box. That is, the combined hopper 100 of the present invention is configured in an assembled form.

The combined hopper 100 is configured on the front of the asphalt concrete and accommodates the asphalt concrete received from the feeder or dump.

The combined hopper 100 is configured on the front side of the finisher 10 and is in the form of a loading box accommodating asphalt concrete and can accommodate a large amount of asphalt concrete. On the upper part of the combined hopper 100, the double-shaped cover is composed of slopes, and the inner cover extends at an angle higher than the right angle, that is, in an oblique shape, to maintain heat and circulate the heat in the hopper 100. 110 and the inner cover 110 is extended in an oblique shape again, the outer cover 120 is configured to accommodate the ascon supplied from the feeder without falling to the outside in the form of a funnel.

One end of the conveyor belt 200 is placed in the hopper before assembly at the center of the lower surface of the assembled combined hopper 100, and asphalt concrete constantly supplied by the combined hopper 100 as described above is of the finisher 10. It is transported to the rear side and rotated regularly by the motor. At this time, the speed of the finisher 10 is appropriately managed according to the amount of asphalt concrete introduced through the conveyor belt 200 .

The conveying screw 300 configured at the end of the other end of the conveyor belt 200 forms a rotating screw and is driven by a motor.

The transfer screw 300 is composed of two screws 310 composed of both sides that transfer the asphalt concrete received from the conveyor belt 200 from the center to both sides. One of the screws 310 constituting the transfer screw 300 is transferred to the left and the other to the right to evenly distribute the asphalt concrete so as to be evenly laid on the road surface. The lower surface of the screw 310 may be configured with a slit at the bottom so that the asphalt can fall evenly to the floor.

The flattening unit 400 is formed on the rear surface of the finisher 10 and flattens the asphalt evenly transported from the top to the bottom. The asphalt is firmly compacted while repeatedly moving from top to bottom using hydraulic pressure to the rear side adjacent to the flattening unit 400.

An operator operating the finisher 10 controls the combined hopper 100, the conveyor belt 200, the transfer screw 300, and the flattening unit 400 through the console 700.

On the other hand, the mixing means 500 is configured inside the combined hopper 100, and the hot wire 550 is provided inside the body of the hopper.

First, the mixing means 500 includes a battery 510, motors 520 and 522, and rotating cones 530 and 532.

The battery 510 supplies power to the mixing means 500 and the second hot wire 550 .

Motors 520 and 522 are composed of two. The motors 520 and 522 are configured on the inner side of the combined hopper 100. The motors 520 and 522 are driven by receiving power from the battery 510 and supply the power by changing the polarity at regular intervals.

The rotating cones 530 and 532 are composed of two, and are configured on the inner side of the combined hopper 100 at the corresponding positions of the motors 520 and 522 described above, and are driven by the motors 520 and 522, respectively. . The polarity of the battery 510 supplied to the motors 520 and 522 is changed at regular intervals and supplied, and rotated sequentially clockwise and counterclockwise at regular intervals by electric power to be accommodated in the combined hopper 100 ascon mix The rotary cones 530 and 532 may be configured to be deflected outward from the center of the combined hopper 100, and the asphalt concrete on the side of the combined hopper 100 is also well mixed.

First, one of the two rotating cones 530 and 532 will be described. A spiral blade 531 is formed around the rotating cone 530 protruding in the form of a cone. When the rotating cones 530 and 532 rotate, the polarity of the motor 520 changes at regular time intervals so that the rotating direction changes, and the asphalt cone is better mixed as the rotating direction changes. In addition, the connection line connecting the rotary cone 530 and the battery 510 is connected to the inside and is maintained long enough, and the direction of rotation is changed at regular time intervals, so the wire is not wound infinitely. In addition, a wheel (not shown) for winding and unwinding a connection line connecting the rotary cone 530 and the battery 510 may be configured inside.

On the other hand, the longitudinal central portion of the combined hopper 100 of the present invention, that is, the portion corresponding to the conveyor belt 200 is formed with a through hole. Rotating cones 530 and 532 are installed on the inner side of the combined hopper 100 on both sides of the conveyor belt 200 installed in the center. Meanwhile, a first hot wire 534 is also disposed inside the rotating cones 530 and 532 . Therefore, heat is applied to the ascon being mixed.

The second hot wire 550 is disposed on the front side and is installed inside the combined hopper 100 for accommodating asphalt concrete in the form of a loading box. In particular, since the second heat wire 550 is configured on the inside of the combined hopper 100 and can maintain the heat of the asphalt concrete, it is possible to increase the length of the combined hopper 100 to accommodate a larger amount of asphalt concrete.

Although not described in detail in the embodiment of the present invention, the console 700 scans the road surface and calculates the amount of asphalt concrete to be laid when the height of the asphalt concrete to be laid is set, and finishes the finisher 10 according to the amount of asphalt concrete to be laid. It is possible to control the operating speed of the conveyor belt 200 and the rotational speed of the conveying screw 300 and the rotating roller 500.
