technical field

The utility model relates to the field of crawler-type shot blasting machines, in particular to a crawler-type shot blasting machine with a high degree of automation.

Background technique

Crawler shot blasting machine is a kind of equipment used for cleaning and strengthening of castings and forgings, small round springs, bearings and other workpieces. It mainly removes the rust, oxide scale, and molding sand on the surface of the workpiece, and can also reduce the internal stress of the workpiece and improve the fatigue resistance of the workpiece.

The Chinese patent with the publication number CN207669136U discloses a new type of crawler type shot blasting machine, which includes a cleaning room, a shot blasting device, a conveying device, a hoist, a separator and a dust collecting device.

The shot blasting machine is connected, and the dust collecting device is connected with the cleaning chamber and the separator. The workpiece is placed on the crawler in the cleaning room. During the rotation of the crawler, the workpiece is turned over. At the same time, the shot blasting machine continuously ejects small spherical particles, and the particles will fill the gap between the workpiece and the workpiece. The workpiece is in the process of turning over. In the process, the workpiece rubs against the ball, so that the rust on the surface of the workpiece is polished off by the ball, and the dust collecting device continuously sucks air, so that the rust on the surface of the ball is continuously absorbed into the dust collecting device.

This new type of crawler type shot blasting machine is equipped with a removable cover plate on the cleaning chamber to prevent the workpiece from being separated from the cleaning chamber. However, this requires manual disassembly and assembly of the cover plate, and the workpiece needs to be manually placed into the cleaning room and then taken out from the cleaning room, which requires more labor costs, so a more automatic shot blasting machine is designed.
