The present invention relates to shot blasting machinery, and more specifically, to shot blasting machinery having a opening/closing means to open or close a moving recess formed lengthily and cut on an upper portion of a processing chamber in a front/rear direction to allow a workpiece to enter into the processing chamber to seal the moving recess during shot work and open the moving recess after the shot work. The shot blasting machinery according to the present invention shoots a shot such as a steel ball to a workpiece at a high speed to process a surface of the workpiece, and comprises: a processing chamber provided with a work space formed therein for shot work and a moving recess formed lengthily on a ceiling thereof along an entering direction of the workpiece; a transport unit to transport the workpiece into or out of the processing chamber; and an opening/closing means to detect a position of the transport unit through a limit switch disposed on an upper portion of the processing chamber, and adjust a position of a cover which opens or closes the moving recess by a detected signal. |
