Casting shakeout hopper based on timing forward and reverse rotation control

Abstract

The invention relates to a casting shakeout hopper based on timing forward and reverse rotation control. The casting shakeout hopper comprises a hopper body, wherein a discharge opening is formed in the lower end of the hopper body; a support sleeve is mounted on the outer side of the discharge opening; a material guiding sleeve is mounted on the inner side of the support sleeve; the material guiding sleeve is rotationally mounted between the lower end of the discharge opening and an inward folded ring of the support sleeve through a thrust bearing; balls are mounted in a circular groove in the upper surface of the inward folded ring; a support seat is mounted on the inner wall of the discharge opening through a plurality of support rods; a motor protection cover and a motor in the motor protection cover are mounted on the lower surface of the support seat; a rotating shaft is mounted on the output shaft of the motor; connecting rods are connected up and down with the side wall of the rotating shaft; mounting sleeves are arranged at end parts of the connecting rods; the mounting sleeves are propped against the inner wall of the material guiding sleeve and are connected with the outer wall of the material guiding sleeve through screws; stirring shafts are rotationally mounted on the outer walls of the connecting rods and are arranged upwards; stirring blades are spirally connected with the outer walls of the stirring shafts; a control box is mounted on the outer side of the support sleeve; and a timing controller and a forward and reverse rotation controller of the motor are mounted in the control box.

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] Aiming at the above-mentioned shortcomings of the prior art, the applicant researched and improved, and provided a sand shakeout bucket for casting based on timing forward and reverse control, which adopts a continuous agitation structure, effectively prev...
