Self-feeding crusher based on ore classification

Abstract

The invention provides a self-feeding crusher based on ore classification. The self-feeding crusher comprises a crusher body; a feeding hole and a discharge hole are respectively formed in the upper part and the lower part of the crusher body; the self-feeding crusher is characterized by further comprising a material shovel hinged on the crusher body; the material shovel comprises a big lifting arm, a hopper and a flexible material spading plate; the big lifting arm is hinged with the crusher body and is provided with a groove; the hopper is a U-shaped structure plate; an opening end of the hopper is hinged with the end, far away from the crusher body, of the big lifting arm; a pouring hole and a material spading hole are respectively formed at the upper side and the lower side of the hopper; the bottom of the hopper is provided with a trench communicated with the groove; the material spading plate is installed in the groove in a sliding way. According to the self-feeding crusher basedon ore classification, ores are fixed by using the closed end of the hopper, are then scooped up by using the material spading plate and are sealed in the hopper, thus being prevented from sliding onthe ground and being conveniently shoveled up.

Description

technical field [0001] The invention relates to the field of crushers, in particular to a self-feeding crusher based on ore classification. Background technique [0002] Stripping and mining are two important tasks in the production process of open pit mines. At present, the mining process of open-pit mines is basically the same, generally including the processes of loosening and crushing of ore rocks, mining and loading, transportation, and waste discharge. In the process of open mining, stripping must be carried out first, and a certain amount of non-mineral soil covered on the useful ore is removed, and then the useful ore is mined. Mining generally uses one or more of blasting, cutting, excavating, transportation and other processes to extract useful ore rocks in natural mines. [0003] At present, open-pit mining has been using the traditional process of perforation blasting-single-bucket excavation (electric shovel)-car transportation-crusher crushing. One of the pr...

Problems solved by technology

One of the problems existing in the existing crusher is that the workers use a manual shovel to load the material. When loading the material, the manual shovel pushes the ore to slide on the ground, which is not conducive to feeding and the work efficiency is low; the existing problems of the existing crusher The second is that the crushed ore has different sizes and needs to be manually classified according to size, which has high work intensity and low work efficiency
