Movable self-discharging sand hopper device

Abstract

The invention provides a movable self-discharging sand hopper device which comprises a sand hopper, a hoisting crane is arranged above the sand hopper, a hoisting ring is arranged on the outer side wall of the sand hopper, the hoisting crane is connected with the hoisting ring through a steel rope to hoist the sand hopper, and a discharging pipe is arranged at the lower end of the sand hopper; a first discharging port is formed in the lower end of the discharging pipe, a first cover plate is arranged on the lower side of the first discharging port, a second discharging port is formed in the side edge of the lower end of the discharging pipe, a second cover plate is arranged on the inner side of the second discharging port, and a switching mechanism is arranged between the first cover plate and the second cover plate. According to the discharging use requirement, the different discharging ports in the discharging pipe are switched through the switching mechanism, so that sand is discharged in different directions, sand discharging accumulation is reduced, follow-up manual operation is reduced, and the sand discharging device is suitable for production.

Description

technical field [0001] The invention relates to the technical field of mold casting, in particular to a mobile self-unloading sand hopper device. Background technique [0002] In the sand casting process, first place the lost foam in the casting box, and add sand in the casting box, so that the sand will completely cover the lost foam, and leave the guide column of the lost foam on the surface of the sand. The position of the flow column is injected, the lost foam is melted, the space where it is located is occupied by molten iron, and the mold is formed after cooling. In the process of dry sand solid mold casting, the sand in the sand bucket needs to be introduced into the casting box. The existing falling sand buckets are vertically cut to a point during the sand falling process, which easily leads to the accumulation of materials. , the operator needs to make adjustments at all times, so as to ensure the uniform discharge of materials everywhere. Patent No. CN104815952A...
