Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a casting sand feeding and conveying device. Background Technology

[0002] During the casting process, molds are used to shape the casting while casting sand, specifically electrofused ceramsite sand, also known as granulated abrasive sand, foundry sand, or bauxite ceramsite sand, is poured into the mold. Electrofused ceramsite sand is made from high-quality bauxite through processes such as calcination, electrofusion, granulation, and sieving. It is a substitute for quartz sand, overcoming the disadvantages of quartz sand such as a high expansion coefficient, low casting precision, and severe sand adhesion, thus improving the quality of castings. For ease of casting, a feeding and conveying device is used to transport the casting sand.

[0003] Existing casting sand feeding and conveying devices lack the function of screening the casting sand entering the conveyor during actual use. This results in casting sand of varying sizes entering the conveyor, and the accumulation of casting sand of different sizes can easily lead to gaps, thus affecting the casting quality of the castings. Therefore, we propose a casting sand feeding and conveying device to solve the above-mentioned problems. Utility Model Content
