Description

Wear-resistant chute Technical Field The invention relates to the technical field of a chute, in particular to a wear-resistant chute. Background The chute is widely applied to the field of material transportation in industrial production sites, and is mainly used for receiving various solid particles and powdery materials transported by a belt or a pipeline and transporting the solid particles and powdery materials to the next production operation flow. The large-size ore grinding medium is mainly used for transferring ore particles with larger granularity, hardness such as steel balls and the like and grinding mediums with larger weight in mine production operation, and because large-size ore, objects with larger self weight such as steel balls and the like are directly thrown and smashed to the bottom of the chute from a high place, a very large impact effect can be generated on a drop point, so that the chute in the area is seriously worn, the grinding mediums with large hardness and irregularity are worn out, the abrasion of the bottom of the chute can be accelerated, and if slurry leakage or material leakage and the like can be caused when the chute is ground through, the whole production system is stagnated, and larger economic loss is caused. The method has the advantages that the abrasion of the bottom of the chute is delayed by paving grids at the bottom of the chute, when materials flow along the chute, the materials close to the bottom of the chute are accumulated in the grids, after the grids are fully stacked, other materials flow on the surface of the accumulated materials and the top of the grids, friction loss is not generated on the bottom of the chute, and the service life of the chute is prolonged. However, the friction force of the material flowing in the chute is large, when the ore grinding medium with large weight is transported, the ore grinding medium can apply a pulling force to the chute, which moves obliquely downwards along the oblique direction of the chute, and the pulling force can be concentrated to the connecting position of the end part of the chute, so that the connecting end of the chute is easily pulled and deformed. Disclosure of Invention The invention mainly aims to provide a wear-resistant chute which can delay abrasion of the bottom of the chute and can not pull and deform the connecting end of the chute. In order to solve the technical problems, the invention adopts the following technical scheme that the wear-resistant chute comprises: the chute body is divided into an impact section and a flow guiding section along the drainage direction of the chute body, and the impact section is positioned at the position of an impact point of the falling of the upper material; the impact groove is arranged at the impact section and used for receiving materials falling from the upper part, and the materials can be piled in the impact groove; The wear-resisting plate covers the bottom of the chute groove of the flow guiding section, a plurality of grids are arranged at the top of the wear-resisting plate, metal balls are arranged in each grid, and the tops of the metal balls protrude out of the grids. Further, the metal balls are arranged in a rolling manner in the grid. Further, the metal balls are fixedly arranged in the grid. Further, a slope is arranged on one side of the wear-resisting plate corresponding to the impact groove. Further, the impact groove is internally provided with an inclined surface block, the inclined surface of the inclined surface block faces the direction of the diversion section, and the inclined surface is higher than the diversion section and is used for guiding the material falling onto the inclined surface block to the diversion section. Further, a mounting groove is formed in the position of the corresponding inclined surface block in the impact groove, the bottom of the inclined surface block is located in the mounting groove, the inclined surface block can move up and down in the mounting groove, at least one buffer pad is arranged between the mounting groove and the inclined surface block, and the height of the inclined surface block can be changed by increasing and decreasing the number of the buffer pads; At least one waist-shaped groove is vertically formed in the position, away from the corresponding inclined surface block, of the groove wall of the flow guide section, of the impact groove, and bolts penetrate through the waist-shaped groove to enable the inclined surface block to be close to the groove wall of the impact groove.
