Description

Technical Field

[0001] This utility model relates to the technical field of high-strength crushing device for non-coal mine development, and more particularly to a high-strength crushing device for non-coal mine development. Background Technology

[0002] Non-coal mines refer to mines and tailings ponds that extract metallic ores, radioactive ores, and other non-metallic minerals (excluding coal) used as raw materials for petrochemicals, building materials, auxiliary raw materials, refractory materials, and other non-metallic minerals. In the process of mining metallic ores, ore crushing is a crucial step. To ensure safe production and improve the efficiency of subsequent beneficiation and smelting, high-strength crushing devices are typically used to crush the ore.

[0003] Chinese patent CN212882865U discloses a high-strength ore crusher hopper, including a crushing bin. The top of the crushing bin has a feed inlet.

A support is fixedly connected to the side of the crushing bin. An intermittent discharge device is located on the left side of the crushing bin. The intermittent discharge device includes a drive shaft driven by a power mechanism. A turntable is located on the surface of the drive shaft near its front end, and a guide block is fixedly connected to the front side of the turntable. This invention, through the combined use of the above structures, solves the problem that in actual use, the traditional movable sealing plate is not convenient to open and close, and is easily affected by the lifting height of the output shaft in the ore compression mechanism, making it difficult to achieve a good sealing effect and safety guarantee, causing inconvenience and reducing work efficiency.
