Description

Technical Field

[0001] The utility model relates to the field of coal mines, in particular to a tipping assembly of an automatic cart. Background Art

[0002] A car tipper is a large mechanical device used to unload bulk materials from open railway cars. It is a loading and unloading machine that can flip or tilt rail cars to unload materials. It is suitable for ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. Most mine cars in mines are also unloaded using small car tippers. A car tipper can unload 1-4 wagons at a time. Early equipment could only unload 1 wagon, and the largest car tipper could unload 4 wagons. However, large car tippers are convenient for use in large mines, but not for coal mine workshops. When using a small cart, it is convenient to load the gangue with a rake, but difficult to ship.

[0003] Referring to the existing Chinese patent with publication number CN220664245U, a system for transferring residual materials after unloading by a tipper is disclosed; a residual material conveyor is used to transport the residual materials and cooperates with a transfer transport component for transfer, and finally the residual materials are transferred to a storage bin for storage. The uninterrupted automatic operation of the residual material conveyor replaces the transfer operation of a cart or a small transport vehicle, which greatly improves the efficiency of transferring the residual materials remaining after unloading by the tipper.

[0004] However, the existing trolley tipping mechanism is generally inconvenient for unloading when in use. When the rail trolley is in use, it still needs to be tipped over manually, which results in a lot of time being wasted during the tipping process, and the work efficiency cannot be effectively improved, and the problem of being unable to realize automated tipping processing can be solved.
