Abstract

The invention discloses a sand mixing machine, which comprises a frame, a lifting frame, a lifting motor, a turning frame, a turning motor, two sand mixing buckets and two sand mixing motors, the lifting frame is arranged on the frame, and the turning motor is installed on On the lifting frame, the turning frame is rotated and set on the lifting frame, and the two sand mixing buckets are arranged on the turning frame. There is a stirring shaft in the sand mixing bucket, and a stirring blade is set on the stirring shaft. One end of the stirring shaft is connected from the sand mixing bucket. One end extends out of the sand mixing bucket, and the agitating shaft extends out of the sand mixing bucket. A connecting piece is provided at one end of the mixing bucket, and an internal spline is arranged on the connecting piece. The sand motor is arranged on the top of the frame, and the output shaft end of the sand mixing motor is provided with an external spline that can cooperate with the internal spline on the connecting key. The present invention is provided with two sand mixing tanks, and when one sand mixing tank is mixing sand, the other sand mixing tank discharges sand outwards, which reduces the downtime of sand discharging and improves the sand mixing efficiency of the present invention.

Description

technical field [0001] The invention relates to a sand mixer, which belongs to the technical field of sand box casting. Background technique [0002] In the field of sand box casting, the sand mixer is an indispensable tool. It is a machine that uniforms the foundry sand, binder, additive, water, etc. and makes it into molding sand or core sand with certain properties. The existing sand mixer comprises a sand mixing cylinder, a motor, a stirring shaft, a stirring paddle, etc., and the motor drives the stirring shaft and the stirring paddle to rotate, so as to stir and mix the sand in the sand mixing cylinder evenly. When the existing sand mixer is unloading, the sand in the sand mixing cylinder is discharged from the shutdown, and then new sand is added to the sand mixing cylinder. After the above actions are completed, the motor is turned on to continue sand mixing. The existing sand mixer Long downtime and low sand mixing efficiency. Contents of the invention [0003] ...
