Sand mixing device for foundry processing

Abstract

This utility model belongs to the field of sand mixing technology for casting processing, specifically a sand mixing device for casting processing. It includes a support frame, within which a mixing box is fixedly connected. The mixing box contains a crushing mechanism and a mixing mechanism. The crushing mechanism includes two crushing rollers, which are mounted in the mixing box via rotating shafts. A first gear and a second gear are respectively fitted onto one end of each shaft, and the first and second gears mesh with each other. A first motor is mounted on one side wall of the mixing box away from the first gear, and the output end of the first motor is connected to one end of one of the rotating shafts. A protective cover is mounted on the other side wall of the mixing box. This utility model employs a method of crushing first and then mixing, which allows the sand and gravel raw materials to be evenly distributed with other raw materials, forming stable molding sand, thus helping to improve the dimensional accuracy and processing quality of castings.
