Also, on the lower side of the second surface 422, there is a part that partially protrudes further downward, and this is called a safety stopper 423. The safety stopper 423 formed on the second surface 422 serves to limit the rotation angle at which the bucket 400 is rotated when the bucket 400 rises on the rail frame 200, reaches top dead center, and rotates. Do it. In other words, when the bucket 400 is rotated for a dumping operation, the maximum rotation angle of the bucket is limited to prevent safety accidents from occurring due to excessive rotation. This is related to the side member, which will be described later, and will be discussed again in that section. Let’s explain the function of the safety stopper.

The bucket 400 is equipped with a link body 600 and a second wheel 700 as well as the mentioned first wheel 500. The upper end of the link body 600 is lower than the first wheel 500 and the bucket ( It is rotatably connected to the left and right sides of the bucket 400, and the lower end has a structure that can be supported while contacting the lower back of the bucket 400.

More preferably, the driving unit is provided with a protection box 900, and the motor and drum, etc. are surrounded and protected by the protection box 900. In particular, the protection box 900 is divided into left and right sides and is divided into a first box ( 910) and the second box 920 are mutually restrained while facing each other so that the protective box can be conveniently removed during repair. The first box 910 and the second box 920 are installed facing each other, an opening hole 901 through which the cable 800 passes is formed on the upper side, and a fastening ring 902 is placed on the side side. The first box 910 and the second box 920 can be simply connected or disconnected with the fastening ring 902.

In addition, the heavy material dumping device of the present invention can be provided with a controller box 1000 on one side of the rail frame 200, and the operation of the driving unit can be controlled through a wired or wireless remote control.

Hereinafter, an operation example of the heavy material dumping device according to the present invention will be briefly described.

With the bucket 400 located at the bottom dead center, the package containing the contents is loaded into the bucket 400. At this time, a plurality of anti-separation pins attached to the bucket penetrate the package, and the package contains the contents. The top is left open.

When the driving unit is raised using the remote control, the cable 800 is wound around the drum and pulls the bucket 400, and accordingly, the first wheel 500 and the second wheel 700 are moved to the rail groove of the rail frame 200. 210), it gradually moves upward while moving through the clouds. After passing the straight section of the rail frame 200, it enters the curved section, and when the upper sensing piece 611 touches the first sensor S1, it is recognized as having reached top dead center, and the operation of the driving unit automatically stops, and at the same time, The bucket naturally rotates and flips over to a predetermined angle.

At this time, in order to limit the maximum rotation angle of the bucket 400, the side member 610 is brought into contact with the safety stopper 423 formed on the second surface 422 of the upper bracket 420, so that the bucket 400 can no longer be used. Make sure it does not rotate to prevent safety accidents.

As the bucket 400 rotates, the contents of the package are naturally discharged and fall. When all the contents fall, the operator presses the lowering button using the remote control, and the driving unit rotates in the reverse direction and operates to release the cable, causing the bucket to gradually lower again. I do it.

The bucket 400 is gradually lowered, and when the lower sensing piece 612 touches the second sensor S2, it is recognized as the bottom dead center, and the driving unit automatically stops operating.

In this way, the heavy material dumping device of the present invention enables efficient operation by simple remote control operation without requiring a lot of force when repeatedly pouring heavy materials contained in a bag.

This design is a technology that can be useful when repeatedly dumping various raw materials supplied in bags.
