Description

Novel combined structure of material guide groove and fixed walking end beam for scraper reclaimer Technical Field The invention relates to the field of bulk material conveying equipment, in particular to a novel combined structure of a material guide groove and a fixed walking end beam for a scraper reclaimer. Background The cantilever side type scraper reclaimer is widely applied to the mixture and auxiliary material yards of modern cement plants, smelting plants, wharfs and the like and is used for treating various materials such as sandstone, gypsum, clay, iron powder and the like. The pre-homogenization of raw materials and auxiliary materials in cement plants is an important link of modern dry cement production lines, and various materials participate in the production process of clinker and cement. The mixed material pre-homogenizing storage yard and the material piling and taking equipment thereof have the functions of storage and partial pre-homogenizing. The key point of the tilting head type side type scraper reclaimer is that the concrete slope of the traditional stockpile is removed, and the concrete slope is changed from a horizontal plane to be used for reclaiming materials, so that the storage utilization rate of a storage yard is improved, the investment cost of the construction civil engineering of the storage yard is greatly reduced, and the utilization rate of the storage yard is also improved.
