Problems solved by technology

In the existing sand mixer, since the movable position range of the stirrer is fixed, in the actual mixing process of the molding sand, there is still a stirring dead angle that the stirrer cannot touch, resulting in uneven mixing uniformity of the molding sand. Good, and the mixing efficiency is not high

Abstract

The invention discloses a molding sand mixing device used in wear-resistant steel casting. When in use, the rotation of the output shaft of the motor can not only drive the stirring blade on the stirring assembly to turn over in the longitudinal direction, but also can be connected with the ring platform by the revolving gear. The meshing and rotation of the ring teeth realizes that the steering component drives the stirring blade to turn over and stir in all directions, so that the molding sand raw materials in the spherical mixing tank can be stirred and turned in all directions, avoiding dead corners of stirring, and significantly improving the sand mixing efficiency and sand mixing of molding sand raw materials. quality; after the molding sand raw materials are evenly mixed and unloaded, the discharge door can also be closed, and the motor can be started to drive the stirring assembly and the steering assembly to continue to move, so that the arc-shaped scraper on the stirring blade can make the residual molding sand raw material adhered to the inner wall of the spherical mixing tank Scrape off, and finally turn off the motor, open the discharge door to discharge the scraped molding sand raw materials, to ensure the cleaning convenience of the spherical mixing tank.

Description

technical field [0001] The invention relates to the technical field of sand mixers, in particular to a molding sand mixing device used in wear-resistant steel casting. Background technique [0002] In the production of wear-resistant steel, casting technology is an extremely important processing technology. Casting is to melt solid metal into liquid, and then pour the liquid metal into the mold to cool and solidify to obtain castings. Molding sand for casting molds is usually made of fine sand by adding a certain proportion of binder or other auxiliary materials, and then stirring evenly. . Since the casting of wear-resistant steel must avoid defects such as pores and inclusions in the casting, the requirements for the uniformity of the casting mold sand are extremely high. [0003] The traditional sand mixing method usually uses manual sand mixing, which consumes a lot of manpower and time, so manual sand mixing has now been replaced by sand mixers. Sand mixer, as the na...
