A kind of sand mixing equipment

Abstract

The invention relates to foundry machinery, specifically to sand mixing equipment. The sand mixing equipment comprises a cylinder, a rotation shaft, a driving motor, a watering device, a valve device, a sand rolling device, a sand fluffing device, a sand-casting device and a scraper plate. The cylinder is a hollow cylinder structure. The bottom of the cylinder is provided with a fan-shaped opening. A support plate is arranged at the opening. The opening is used for releasing mixed sand. The support plate is provided with through-holes. The rotation shaft is installed at the middle part of the cylinder. The driving motor is positioned below the cylinder. The watering device is positioned above the rotation shaft. The valve device is installed at the bottom of the cylinder. The sand rolling device, the sand fluffing device, the sand-casting device and the scraper plate are uniformly installed on the periphery of the rotation shaft. The scraper plate is positioned at the bottom of the cylinder. The sand mixing equipment has a simple structure. By effectively integrating a muller, a sand fluffing rod, a plough and the scraper plate, rolling, grinding, stirring and turning-over of a material are realized, and sand-mixing efficiency of the sand mixer is enhanced.

Description

technical field [0001] The invention relates to a foundry machine, in particular to a sand mixing device. 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 between the two...

Problems solved by technology

But above-mentioned sand mixer also has the place that still needs to be improved, and the edge of one side of the roller of roller type sand mixer is evenly provided with loose sand bar, does not make full use of the space of roller and sand mixer inner wall, simultaneously, scraper is in the mixing The bottom of the sand machine, and the size of the scraper is small, the foundry effect needs to be improved
