Description

[Detailed Description of the Invention] The present invention relates to a fan-shaped ladle in an automatic pouring device. As shown in FIG. 3, the conventional fan-shaped ladle 20 has a molten metal discharge hole 21 provided in the upper part of the ladle body 22, and the ladle 20 is rotated in a direction opposite to the rotational direction of the hot water. I was trying to drain the remaining hot water. For this reason, the position at which the remaining hot water is discharged changes with the rotation of the ladle 20, making it necessary to prepare a large hot water receiving container 23. Therefore, the workability was poor, the discharge took a long time, and the head was large and dangerous. The present invention aims to solve these problems.

The configuration of the present invention will be explained below based on examples. 1 is a ladle, and the ladle 1 has a tooth pattern 1 on the outer peripheral surface of the tip.
A fan-shaped ladle body 2 with a engraved shape, a pouring hole 3 provided on both sides of the ladle body 2 on the axis of rotation, and a discharge hole consisting of a hole larger than the diameter of the pouring hole 3. 4, and a funnel-shaped replenishment port 5 provided in the upper part of the ladle body 2 near the discharge hole 4. Also,
The ladle 1 has a pair of bearings 7, 7 whose rotating shafts at both sides are attached to the upper surface of the pedestal frame 6.
A drive gear 9 is engaged with the toothed die 1a, and a drive device (not shown) is connected to the drive gear 9. Due to the operation of the ladle 1
is adapted to be tilted in forward and reverse directions via a drive gear 9. 10 is an opening/closing lid of the discharge hole 4, and the opening/closing lid 10 is attached to a support shaft 12 supported by a support member 11.
The discharge hole 4 is rotatably supported via a support arm 13, and a stopper 15 is engaged with a stopper 14 so that the discharge hole 4 can be sealed by the opening/closing lid 10. 1
Reference numeral 6 denotes an openable/closable lid provided on the upper surface of the replenishment port 5 so that the replenishment port 5 can be hermetically sealed. 17 is an inspection window provided on the upper surface of the ladle body 2, and the inspection window 17 is provided with an opening/closing lid 18. With this structure, the ladle 1 begins to be tilted counterclockwise at a constant speed in FIG. However, when a predetermined amount of molten metal has been dispensed, a completion signal is sent to stop dispensing the molten metal. In this way, tapping is repeated, and when the molten metal runs out, the lid 16 of the replenishing hole 5 is opened to replenish the ladle 1 with molten metal. Also, when the work is finished,
The ladle 1 is rotated counterclockwise by continuing the rotation during tapping, and the remaining hot water in the ladle 1 is gradually raised, and the lid 10 of the drain hole 4 is opened to drain the remaining hot water from the drain hole 4. It is discharged into a hot water receiving container (not shown) below. After the remaining hot water is discharged, the ladle 1 is returned to the starting position by the reverse rotation of the drive gear 9 in preparation for the next operation.

As is clear from the above explanation, according to the present invention, in a fan-shaped ladle that can freely tilt forward and backward around the rotation axis, the pouring hole is formed on one side on the rotation axis, and the pouring hole is formed on the other side. Since the discharge hole is provided in each of the holes, the discharge position of the remaining hot water is always at a fixed position and does not change due to the rotation of the ladle, and the container for receiving the hot water only needs to have a small area. When draining hot water, there is no need to rotate the ladle in the opposite direction.
It has good workability, can shorten the discharge time, and can reduce the head difference, so it has the advantage of being non-hazardous and has a significant effect on this type of industry.
