Description
Technical Field
[0001] The utility model relates to the technical field of sand mixer equipment, in particular to a sand mixer which is convenient for unloading. Background Art
[0002] Sand mixer refers to the equipment that evenly mixes the components in the molding sand and effectively coats the surface of the sand particles with the binder. The main equipment for mixing the molding sand in the foundry sand processing is the sand mixer, which is also the key equipment for obtaining qualified molding sand. The sand mixer uses the relative movement of the grinding wheel and the grinding plate to crush the material placed between the two by rolling and grinding. The sand mixer can mix the material while crushing it. It is an ideal equipment for producing unburned bricks, refractory bricks, crushed bricks, lime sand bricks, cement bricks and mixed fly ash, boiler slag, tailings slag and industrial waste slag as raw materials for brick making;
[0003] After searching, the applicant found that a Chinese patent disclosed "a sand mixer that is easy to unload", and its publication (announcement) number is "CN214290683U". This patent mainly uses a machine body, a leg, a discharge pipe, an L-shaped fixed plate, a fixed pad, a motor, a semi-movable gear, a toothed plate, a connecting block, a transmission column and a top column to coordinate the use of the inside of the discharge pipe by moving the top column up and down, so as to achieve the effect of facilitating unloading, enhance the efficiency of unloading, and enhance the practicality of the sand mixer. This sand mixer that is easy to unload solves the problem that the existing sand mixer cannot completely discharge the mixed molding sand when unloading sand, and the undischarged sand sticks to the discharge port of the sand mixer for a long time. After the molding sand hardens, it becomes very troublesome to remove it from the discharge port of the sand mixer. However, in the original application document, when the device is in operation, the cover plate is easy to shake, causing the internal sand to fall off. For this reason, we propose a sand mixer that is easy to unload. Utility Model Content
