Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling sand cutting device, and more particularly to a filling sand cutting device for a ladle nozzle.

[0002]

2. Description of the Related Art For example, in a ladle having a nozzle (a ladle nozzle) at a bottom portion such as a molten steel ladle, the ladle nozzle before starting to be used is protected from nozzle blockage at the time of pouring a tundish. It is a common practice to fill the nozzle hole of a pot nozzle with sand called filling sand (some types may be used). This sand stuffing operation is a simple operation of putting sand into a sand stuffing work cup installed at the ladle setup site.However, conventionally, an operator manually transports a bag containing sand, It was carried out in a way that each type was thrown into a sand-filling work cup.

[0003]

The above-mentioned conventional system has a problem that the load on the worker is very large. Also,
Since only one type of sand can be loaded at a time,
If you use different kinds of sand, you need to carry it twice.
There was also a problem that it took time to work. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a clogging sand cutting device capable of automating the work of filling a ladle nozzle with sand.

[0004]

SUMMARY OF THE INVENTION The present invention provides a plurality of bunkers having a sand receiving port at an upper portion and a sand discharging device at a lower portion, a bucket for receiving sand discharged from the sand discharging device, and a bucket for receiving the sand discharged from the sand discharging device. A lifter for raising and lowering, a tilting mechanism for tilting a bucket at an upper end of the lifter, and a chute for receiving sand discharged from the tilted bucket and guiding the sand to a sand filling work cup. It is a filling sand cutting device for pot nozzle.

[0005]

1A and 1B show an embodiment of the present invention. FIG. 1A is a side view, and FIG. 1B is a rear view. As shown in the figure, in the present invention, a plurality (two in this example) of bunkers 1 and 2 (the gantry 6 is a frame) having sand receiving ports 91 and 92 in the upper part and sand removing devices 81 and 82 in the lower part. ). The capacity of each of the bunkers 1 and 2 is preferably a capacity that can store sand several times at a time. Each of the bunkers 1 and 2 may be provided with a partition plate inside one container, for example.

The present invention also relates to a bucket 3 for receiving a proper amount of sand discharged by the sand discharging devices 81 and 82 in a timely manner;
A lifter 5 for raising and lowering the bucket 3 is provided. And
At the upper end of the lifter 5, there is provided a tilting mechanism 10 for tilting the bucket 3 containing sand lifted by the lifter 5, and further, a chute 7 receiving the sand discharged from the tilted bucket 3 at the upper end. This chute 7 is designed such that sand sliding down along the slope falls from the lower end of the chute 7 into the sand filling work cup 4.

[0007] The components constituting the present invention (sand removing device)
81, 82, tilting mechanism 10, etc.) can be easily configured according to a conventional method. With this configuration, sand is discharged from the lower portions of the bunker 1 and 2, the sand is once received by the bucket 3, the bucket 3 is lifted by the lifter 5, and then tilted by the tilting mechanism 10 to shoot the sand in the bucket 3. 7 can be automatically performed, and a heavy work such as a worker carrying a sand bag can be greatly reduced. It goes without saying that the sand transferred to the chute 7 is conveyed to the lower end of the chute 7 by gravity, and falls freely into the sand filling work cup 4 therefrom.

Further, according to the present invention, since a plurality of bunkers 1 and 2 are provided, different kinds of sand are stored for each of the bunker 1 and 2, and different kinds of sand are appropriately mixed according to the application. Can be used. That is, since it is not necessary to transport the sand bags to the sand-filling work cup 4 for each type of sand as in the related art, the work time is also reduced. Also, when compared with a method of directly putting sand into the cup from a bunker provided above the cup (an alternative method (not shown) according to the study of the inventors),
The use of the chute 7 allows the different types of sand to slide down while interfering with each other, thereby increasing the uniformity of mixing. The use of the lifter 5 allows the height of the bunker 1 and 2 to be reduced, thereby further reducing the size. Therefore, it is easy to put sand into the sand receiving ports 91 and 92, and the occupied space can be reduced.

In this embodiment, an example in which two bunkers are provided is disclosed. However, it is obvious that the present invention can be applied to a case where there are three or more bunkers.

[0010]

According to the present invention, the work of filling the ladle nozzle with sand can be automated with a compact device, and the load on the operator in the work can be reduced and the work time can be shortened. .
