Patent number: 7766725Abstract: A loader arrangement 7 of a shot-blasting machine includes a bucket loader 29 having a tip opening that can be opened and closed by means of a lid 35. The loader arrangement 7 also includes a swivel arm 32, which is vertically and pivotally attached to a frame 4 via a linkage 31, for vertically swiveling the bucket loader 29, and a chain block 34 for swiveling the arm 32. Once the bucket loader 29 has reached the upper position above a rotary drum 5 by means of the swivel arm 32, a guide means 30, which is attached to the arm 32, allows the bucket loader 29 to approach the drum 5 through its top opening by driving a hydraulic cylinder 33, while the tip of the bucket loader 29 is opposed to the bottom wall of the drum 5. Once the tip of the bucket loader 29 is close to the bottom wall or the inner peripheral wall of the drum 5, the lid 35 is opened to drop the work pieces in the bucket loader 29 into the drum 5.Type: GrantFiled: April 6, 2006Date of Patent: August 3, 2010Assignee: Sintokogio, Ltd.Inventors: Mitsugi Umemura, Takayuki Nakada, Hiromasa Miura
