Description

Technical Field

[0001] The utility model relates to the technical field of waste boxes, in particular to a welding slag waste box with double doors at the bottom which are opened and closed by a connecting rod. Background Art

[0002] Welding slag is mainly composed of molten metal and electrode coating. It is the incomplete and irregular metal or non-metallic material left on the welding joint or weld. It is composed of residual materials in the welding pool and is an inevitable waste in the welding process. The welding slag is cleaned from the weld in the form of debris particles, which can be used to make building materials, etc. Since the welding slag is in the form of debris and has a high density, the storage of welding slag requires a strong and solid closed container to prevent the debris from scattering. At present, the welding slag is stored in a barrel and then poured into a waste box with an opening on the top, a bottom surface and surrounding welds (the cross-section of the waste box is a right-angle trapezoid, and a lifting lug extends upward from the hypotenuse of the trapezoid). After the waste box is full, the forklift lifts the waste box filled with welding slag from the bottom and transports it to the welding slag truck. The driving crane lifts the lifting lug on the waste box, drags the lifting lug to overturn the waste box, and the welding slag falls on the truck. This welding slag waste box has only one opening on the top. The welding slag is poured in from the top and poured out from the top. Because the box full of welding slag is heavy, it is necessary to use a vehicle to drag the waste box to dump it, which poses a safety hazard. Therefore, it is necessary to design a waste box that can pour welding slag from the top and pour welding slag from the bottom to avoid the top opening for entry and top opening for exit.
