Description

A casting waste collection device for a foundry workshop

Technical Field

The utility model relates to the technical field of casting waste collection, in particular to a casting waste collection device produced in a foundry workshop.

Background Art

Castings are formed objects obtained by various casting methods, that is, the smelted liquid raw materials are poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with certain shapes, sizes and properties. Casting waste refers to castings that cannot be used normally or repaired during the casting process. These wastes are usually caused by various factors in the casting process, such as casting design problems, casting material selection problems, and operation problems during the casting process.

According to a foundry production casting waste collection device published on the patent website (authorization announcement number: CN214416484U), the foundry production casting waste collection device includes "device body, processing structure, crushing structure, No. 2 collection frame", etc., to crush and collect casting waste.

In view of the above description, the applicant believes that there are the following problems:

The foundry produces a casting waste collection device, which uses the device body, processing structure, crushing structure, No. 2 collection frame, etc. to crush and collect casting waste. This device uses a sliding block to follow the rotating shaft in the slide slot and rotate back and forth to the limit of the slide slot, and then pull the pulling rod, so that the pulling rod drives the movable filter plate to swing back and forth, so that the waste entering the movable filter plate can be vibrated and fall off in sequence. This method has low material discharge efficiency and slow speed, and can cause the casting waste to get stuck, affecting the crushing efficiency, and one-time crushing will result in incomplete crushing, so this device needs to be improved.
