Title: Clamshell bucket
Inventor: KUBO HIROYUKI
IPC: E02F7/00
Filed: 1991-11-26
Abstract: PURPOSE:To improve working efficiency and to reduce size. CONSTITUTION:A clamshell bucket comprises an openable bucket body 10 to perform excavation of a ground G, a link mechanism 20 to open and close the bucket body 10, an expandable motoroperated jack 30 to operate the link mechanism 20, a hoist 40 for support to hang down the bucket body 10, a trolley 50 coupled to the hoist 40 for support, and a guide rail 60 to convey the trolley 50. Through expansion and contraction of the motoroperated jack and through operation of a link mechanism, the bucket body is opened and closed. Thus, a single hoist suffices for operation of the clamshell bucket and the size of the clamshell can be reduced. Since the motor-operated jack is employed, no influence is exercised on powder dust and earth particles, the bucket body is effectively opened and closed, and the working efficiency of the clamshell can be improved.
