Description

Casting is with dead sand breaker Technical Field The utility model belongs to the technical field of waste sand crushing, and particularly relates to a waste sand crushing device for casting. Background A granular refractory material for use in foundry production for preparing sand and core sand. Under the condition that clay is used as a molding sand binder, 1 ton of new sand is required to be supplemented every 1 ton of qualified castings, so that the amount of casting sand is huge in sand casting production, and the waste casting sand is required to be crushed again after being recovered, the traditional pendulum crusher is high in crushing speed, the crushing effect is difficult to achieve the expected effect, more large-diameter granular sand exists in the crushed sand, repeated crushing is required, the repeated crushing amount is large, electric energy is greatly consumed, and the production cost is increased, so that the waste casting sand crushing device for the sand is provided, and the technical problems are solved. Disclosure of Invention The utility model aims to solve the technical problem of providing a waste sand crushing device for casting, which has a simple structure, is convenient and practical, and achieves the purposes of repeatedly beating and crushing materials again by arranging a beating step on beating powder blocks and arranging a beating inclined surface on the beating step, so that the beating angle is increased, and the beating inclined surface can throw the crushed raw materials upwards. The utility model provides a casting is with waste sand breaker, includes crushing case, feeder hopper, power motor, power band pulley, auxiliary band pulley, rotation main shaft, rotatory crushing group, drive belt and mount, crushing case is fixed on the mount, the feeder hopper sets up at crushing case top, crushing case bottom is provided with the discharge gate, power motor connects on the mount and power pole is connected with the power band pulley, rotation main shaft swing joint is in crushing incasement and one end runs through crushing case bottom and is connected with auxiliary band pulley, the power band pulley passes through the drive belt and is connected with auxiliary band pulley transmission, a plurality of rotatory crushing group is connected on rotating the main shaft, rotatory crushing group is including carousel, beat bull stick, pivot, hypoplastron and guide ring, carousel and hypoplastron are connected on rotating the main shaft, the carousel sets up in the hypoplastron top, a plurality of the pivot is connected between carousel and hypoplastron, beat bull stick and beat one end and beat and smash piece swing joint and be connected in corresponding pivot, the guide ring is connected on crushing case inner wall, beat the powder piece setting between carousel and guide ring.
