Description

Technical Field

[0001] The utility model belongs to the technical field of casting, and particularly relates to a casting material stirring device. Background Art

[0002] The casting material stirring device is a device that evenly mixes the components in the molding sand and effectively coats the binder on the surface of the sand particles. Among the existing stirring equipment, the larger sand mixing equipment can achieve continuous sand mixing with high sand mixing efficiency and good sand mixing effect, but there are many processes. During the stirring process of the casting material, a large amount of dust is generated, which can easily cause pneumoconiosis and pollute the environment. At the same time, the sand mixing mode of the casting material stirring device is small batch quantitative mixing of casting sand. Due to its small size, it is easy to transport and maintain, and has high flexibility, but there are problems such as extremely low sand mixing production efficiency, easy to have stirring dead corners, uneven sand mixing, etc.

[0003] For example, a Chinese patent with publication number CN209520333U discloses a casting material stirring device, which includes a cylindrical container with an opening upward and fixed, the outer edge of the lower side surface in the container cavity is an arc transition, there is an actively rotating shell in the container, a first fixed bevel gear is provided at the lower end of the shell cavity, a plurality of second bevel gears are meshed around the first bevel gear, the second bevel gear has a rotating shaft coaxial with the first bevel gear, the lower end of the rotating shaft extends out of the shell, the lower end of the rotating shaft is inclined to a side away from the center of the container, a plurality of stirring rods are provided on the rotating shaft that are perpendicular to the rotating shaft, and the lower end of the rotating shaft contacts the lower side surface in the container cavity.

[0004] Although this patent effectively improves the stirring efficiency, there are unreasonable problems in the patent structure. For example, the arc plate rotates with the shell in the inner cavity of the container, and rotates on its own driven by the first gear, the second gear and the rotating shaft. First, the rotating shaft drives the stirring rod and the arc plate to rotate under the resistance of the casting sand, which makes the second gear and the first gear severely worn and easy to be damaged. At the same time, hydraulic cylinders and piston rods are connected on both sides of the plate, so that the plate can be easily lifted up and down, but the plate is not convenient to move, resulting in the need to raise the plate in advance for feeding, then pour the casting material, and then lower the plate, resulting in inconvenient operation process.
