Problems solved by technology

[0004] Traditional wheel-type sand mixers generally only have a wheel structure, or have both a wheel structure and a sand-foundation structure, but the wheel structure and the sand-foundation structure are independent and separate, and the scattered structures are troublesome to install, and it is inconvenient to disassemble and assemble for maintenance. The roller of the traditional roller structure is rolled for a long time, and it is easy to form a bonding layer on the surface. The cured adhesive block layer will greatly reduce the rolling and rubbing effect of the roller structure, but the direct cleaning is located in the sand mixer. The roller inside is very inconvenient

Abstract

The invention relates to a casting sand mixer. The casting sand mixer comprises a machine base, a round sand mixing hopper, a rotating motor assembly, a wheel train transmission mechanism, turning andgrinding assemblies and a scraping plate mechanism, the round sand mixing hopper is fixedly arranged on the machine base, the rotating motor assembly is fixedly arranged at the central position of the bottom of the machine base, the wheel train transmission mechanism is fixedly arranged at the top of the rotating motor assembly, the two turning assemblies are symmetrically and rotationally arranged on the wheel train transmission mechanism, and the scraping plate mechanism is fixedly arranged on the wheel train transmission mechanism; the rotating motor assembly can drive the wheel train transmission mechanism, the whole synchronous rotation formed by the turning and grinding assemblies and the scraping plate assembly is achieved, the wheel train transmission mechanism can drive the two turning and grinding assemblies to rotate. According to the casting sand mixer, the grinding roller and the sand turning structure of the casting sand mixer are uniform and compact in design and convenient to dismount and maintain, cleaning and rapid replacement of the grinding wheel structure are facilitated, and the efficiency and quality of sand mixing are ensured.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a casting sand mixer. Background technique [0002] Foundry sand is used in a large amount in sand casting. Foundry sand is a granular refractory material used to prepare molding sand and core sand in foundry production. Molding sand or core sand is generally composed of raw sand, binder, water and additives. Made by mixing in certain proportions. Therefore, a sand mixer must be used in the process of mixing and preparing foundry sand. [0003] The sand mixer is a machine that evenly mixes the raw sand for foundry, binder, additive, water, etc. to make it into molding sand or core sand with certain performance. According to the characteristics of the sand mixing process, the sand mixer can be divided into: the roller type sand mixer with rolling and rubbing as the main function; the blade type sand mixer with the main mixing effect; Countercurrent or rotor sand mixer and ...
