[0002] It is known that casting is a method of pouring a liquid metal into a casting cavity adapted to the shape of the part, and after it cools and solidifies, a part or blank is obtained. The cast material is usually a metal that was originally solid but heated to a liquid state, such as copper, iron, aluminum, tin, lead, etc., while the material of the mold can be sand, metal or even ceramic.

[0003] At present, casting is mainly divided into sand casting and special casting. Sand casting uses sand as a mold material, and sand can be reused and has low cost. Moreover, sand casting has low casting condition requirements and is easy to master, so it has become the most widely used casting method and is widely used in various metal casting industries. However, due to the large amount of sand used in sand casting as a mold material, the total cost of the foundry sand is not low. In order to maximize the use of sand, the foundry sand is often recycled to reduce costs. However, the applicant found that the existing recycling technology of foundry sand often uses a sand loosening machine to break the bulk foundry sand for recycling, but there is still a problem of incomplete crushing and large waste, which increases the production cost and causes resource waste.

[0004] Therefore, in view of the above related technologies, it is necessary to provide a foundry sand recycling and loosening device. CONTENT OF THE INVENTION
