A sand-turning sand mixer

Abstract

The invention relates to foundry machinery, specifically to a sand-casting sand mixer. The sand-casting sand mixer comprises a driving motor, a rotation shaft, a sand-casting device and a runner wheel device. The driving motor is positioned at the bottom of the sand mixer and is connected with the rotation shaft through a shaft coupling. The middle part of the sand mixer is provided with the rotation shaft. The whole body of the sand-casting device is plough-shaped and comprises an elongated plough handle and a base plate. The base plate and the bottom of the plough handle are fixedly connected. The runner wheel device comprises a runner wheel body and sand fluffing rods. One side of the runner wheel body is provided with the sand fluffing rods which uniformly cover one side of the whole runner wheel body. The sand fluffing rods arranged at the edge of one side of the runner wheel body are the shortest. Length of the sand fluffing rods is gradually increasing in the direction towards the central plane of the runner wheel body. The sand-casting device and the runner wheel device are both connected with the rotation shaft through bolts. The sand-casting sand mixer has a simple structure. By effectively integrating a runner wheel and a plough and fully utilizing the space between the runner wheel and the side wall of the sand mixer, rolling, grinding, stirring and turn-over of a material are realized, and sand mixing efficiency of the sand mixer is raised.

Description

technical field [0001] The invention relates to a foundry machine, in particular to a sand-turning type sand mixer. Background technique [0002] The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. Sand mixer is a kind of sand processing equipment widely used in the foundry industry. According to the characteristics of sand mixing process, sand mixer can be divided into: roller type sand mixer mainly for rolling and rubbing; Blade-type sand mixer with main function; countercurrent or rotor-type sand mixer with rubbing and mixing functions, and balance wheel sand mixer with rolling and mixing functions. According to the nature of the work, the sand mixer can also be divided into two types: intermittent and continuous sand mixers. [0003] The grinding wheel sand mixer uses the relative movement of the grinding wheel and the grinding plate, and crushes the material placed betwe...
