Description

Technical Field

[0001] The utility model belongs to the field of shot blasting equipment, and particularly relates to a shot blasting machine. Background Art

[0002] Shot blasting machines are mainly used in the foundry industry for removing surface adhering sand and scale from cast steel and cast iron parts. A shot blasting machine is a mechanical device that uses high-speed shot thrown by a shot blasting device to clean or strengthen the surface of workpieces. A shot blasting machine can simultaneously perform sand falling, core removal, and cleaning on castings. Almost all cast steel parts, gray castings, malleable cast iron parts, ductile iron parts, etc. need to be shot blasted. This is not only to remove the surface scale and adhering sand of the castings, but also an indispensable preparatory process before the quality inspection of the castings. In the process of steel shot recovery by existing shot blasting devices, the scattered steel shots are not easy to recover, and after recovery, the steel shots still need to be separated from the residues generated by cleaning, which reduces the work efficiency.
