Rapid sand grinding equipment for foundry sand

Abstract

The invention relates to the technical field of casting, and discloses rapid sand grinding equipment for foundry sand. The rapid sand grinding equipment comprises a box body, wherein the box body is connected with a feeding mechanism, the feeding mechanism comprises a first motor, a material barrel, an air cylinder and a material guide plate; a first L-shaped plate is fixedly connected to the lower end of the right side wall of the box body; a second L-shaped plate is fixedly connected to the left side of the upper end of the box body; the upper end of a vertical part of the first L-shaped plate is fixedly connected with the right side of the lower end of a horizontal part of the second L-shaped plate; and the lower end of a first motor is fixedly connected with the right side of the horizontal part. By means of the casting sand grinding equipment, the foundry sand can be fed into the equipment rapidly without carrying the foundry sand to a high feeding hopper manually, the labor amount of workers is reduced, the casting sand feeding speed is increased, accordingly, the sand grinding efficiency can be improved, meanwhile, the ground sand can be screened and filtered, and the situation that subsequent casting procedures are affected since the casting sand with large particles flows out is prevented.

Description

technical field [0001] The invention relates to the technical field of foundry equipment, in particular to a rapid sand grinding equipment for foundry sand. Background technique [0002] A granular refractory material used to prepare molding sand and core sand in foundry production. When clay is used as a molding sand binder, about 1 ton of new sand needs to be added for every ton of qualified castings produced. Therefore, in sand casting production Foundry sand is used in the largest amount. [0003] At present, due to the high position of the feeding port of the existing sand grinding equipment, when casting foundry sand into the equipment, it is generally carried and put into the equipment by hand. However, this method requires a large workload and slow delivery speed. The sand grinding efficiency is low, therefore, a rapid sand grinding equipment for foundry sand is proposed. Contents of the invention [0004] The purpose of the present invention is to solve the prob...
