The invention discloses a composite pump shell of a slurry pump and a preparation method and application of the composite pump shell, and belongs to the field of preparation of abrasion-resistant steel and iron materials. According to the invention, targeted composite structure design is carried out, and a high-wear-resistance ceramic hard phase is added into an easily-abraded area of the high-chromium cast iron pump shell by combining a two-step process of blank preparation and casting, so that a composite structure pump shell material and a component which are high in performance and long in service life are finally obtained. The proportion of the ceramic hard phase in the composite area of the pump shell exceeds 60%. The composite pump shell material has excellent anti-scouring and anti-abrasion capabilities, can be used for material conveying of slurry pumps in the fields of mines, dredging and the like, and has good application prospects and practical value.

The utility model discloses a liftable material box formula robot, including body mechanism and setting through the mode of pressing in body mechanism one side, limit carrying material box movement process, the flexible pressing limiting mechanism of swing amplitude of in -case material, reduce the risk of abrasion, move to the required height through the first motor drive lifting plate, and then by second motor will the storage frame adjust to the required angle, through the driving wheel whole device moves to the next point position, before electric slide rail placement box, close cylinder, drive the pressboard reset, lift the elastic piece, make it separate from the height of the contact in -case material top, remove the restriction of position, can effectively reduce in the process of collecting box and back and down in higher position, the shaking of box by device movement influence and produce, cause the material that in -case received between the material between the mutual collision and friction of swing and appear, and reduce the risk of abrasion of in -case material.
