Description

Technical Field

[0001] The utility model relates to the technical field of sand cleaning devices, in particular to a sand cleaning device for forklift counterweight castings. Background Art

[0002] In the foundry industry, sand cleaning is a key post-processing step, which not only affects the appearance quality of the casting, but also the internal quality of the casting. Therefore, an efficient sand cleaning device is of great significance to improving production efficiency and product quality. The sand cleaning device for forklift counterweight casting is particularly suitable for cleaning large castings in foundries, especially for those with complex shapes.

[0003] A common sand cleaning device adopts a box structure with a rotating sleeve on the top. The top plate at the bottom of the sleeve is driven by a motor to rotate, thereby achieving a sand cleaning effect. However, this method can only perform circumferential rotation in the horizontal direction when the motor drives the top plate to rotate, which makes it easy to have dead angles when sand cleaning special positions such as grooves and holes on the surface of the casting, thereby reducing the quality of sand cleaning. In addition, since the processing range of a single circumferentially rotating cleaning mechanism is small, it is impossible to clean all positions on the surface of some special-shaped castings when sand cleaning, which reduces the adaptability of the sand cleaning device and cannot meet the working requirements of casting sand cleaning. Therefore, a sand cleaning device for forklift counterweight casting is proposed. Utility Model Content
