Description

Technical Field

[0001] The utility model belongs to the technical field of metal product production equipment, in particular to a metal product feeding device. Background Art

[0002] During the production process of metal products, the ore raw materials are mainly smelted into molten metal, which is then poured into a mold and waited for cooling and forming before being taken out. After grinding, polishing and cleaning of this part of the metal blank, the finished metal product can be obtained. In the ore smelting process, a feeding device is needed, and the feeding device is mainly represented by belt conveyors, screw conveyors and bucket elevators. Among them, the screw conveyor is the most widely used because of its stable feeding process, and the feeding speed and clinker amount can be precisely controlled. The screw conveyor consists of a feed hopper, a barrel, a power mechanism and a screw. The power mechanism is used to provide power to the screw, and the barrel is used to deliver the ore raw materials, and the feed hopper is used to input the ore raw materials.

[0003] A Chinese patent application with publication number CN219340732U discloses a feeding mechanism for steel production, including a screw conveyor body, an adjusting mechanism is arranged on the outer wall of the bottom end of the screw conveyor body, and a lifting mechanism is arranged on the outer wall of the bottom end of the adjusting mechanism; the adjusting mechanism includes supporting ears, supporting ears are arranged on both sides of the screw conveyor body, and the supporting ears are rotatably connected to the screw conveyor body, and a first mounting plate is fixed on the bottom end between the supporting ears; the adjusting mechanism provided in this scheme adjusts the upper and lower angles of the screw conveyor body through the cooperation of the first hydraulic cylinder and the supporting ears, and can adapt to the feeding in different scenarios, and then the big head bolt is screwed to the connecting groove so that one end of the big head bolt is against the second slider to limit the second slider, so that the first support rod can be stably supported to prevent the first hydraulic cylinder from failing and causing the equipment to tip over and break, thereby improving the safety of the equipment.

[0004] The above-mentioned steel production feeding mechanism has a feed hopper installed on the top of one end of the screw conveyor body, through which the production raw materials are directly fed into it. However, the feed hopper is an open trumpet-shaped structure, which cannot screen raw materials of different particle sizes when feeding, and it is easy to cause raw materials with too large diameters to be stuck at the feeding port; and the trumpet-shaped feed hopper on the screw conveyor body only has the effect of feeding, and cannot perform targeted stone crushing for some ore raw materials with too large particles. When these ore raw materials enter the screw conveyor body through the feed hopper, it will affect the feeding problem. To this end, we provide a metal product feeding device to solve the above-mentioned problems. Utility Model Content
