Anti-blocking shakeout hopper for dry-sand full mold casting

Abstract

The invention relates to an anti-blocking shakeout hopper for dry-sand full mold casting. The anti-blocking shakeout hopper for dry-sand full mold casting comprises a hopper body. The lower end of the hopper body is provided with a discharging outlet. A material guide sleeve is mounted at the discharging outlet. A supporting block is mounted at the center of the material guide sleeve through a plurality of supporting rods. A motor and a motor protecting cover located on the periphery of the motor are mounted at the lower end of the supporting block. A driving shaft of the motor penetrates through the supporting block and is provided with a stirring shaft. The stirring shaft is located above the supporting block and provided with a stirring blade arranged spirally. A control box is mounted on the outer wall of the material guide sleeve. A forward and backward rotation controller of the motor and a timing controller are mounted in the control box, the timing controller is connected with the forward and backward rotation controller, and the driving direction of the motor is changed through the forward and backward rotation controller in a timed mode. According to the anti-blocking shakeout hopper for dry-sand full mold casting, the stirring blade is driven by the stirring shaft to stir sand in the discharging outlet and prevent the sand from blocking the discharging outlet, so that continuous feeding of the discharging outlet is guaranteed, the discharging efficiency is improved effectively, manual maintenance is replaced, and the labor intensity and labor cost are lowered.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to dry sand full mold casting equipment. Background technique [0002] During the dry sand solid mold casting process, the sand in the sand bucket needs to be introduced into the sand separator. During the sand shakeout process of the existing shakeout hopper, the discharge port is easily blocked. The current method is to periodically manually push the push plate arranged in the discharge port, and use the push plate to push the sand blocked in the discharge port to realize falling sand. The above-mentioned anti-clogging method has high manual labor intensity and low sand shakeout efficiency. Contents of the invention [0003] In view of the above shortcomings of the prior art, the applicant researched and improved it, and provided an anti-clogging shakeout hopper for dry sand solid mold casting, which adopts a continuous stirring structure, effectively prevents shakeout from cl...
