Title:
LIFTING DEVICE FOR AUGER DRIVE MECHANISM
Document Type and Number:
Japanese Patent JP3022314
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To facilitate assembly by connecting two auger drive mechanisms in parallel by an upper connecting member and a lower connecting member and installing a lock pin controlling the revolution of the upper connecting member and a control lever for the lock pin to the upper connecting member.
SOLUTION: Auger drive mechanisms 18, 19 are coupled in parallel by upper and lower connecting members 74, 68. Guide gibs 14-17 are disposed to a sheave frame 34 and the lower cormecting member 68. The upper connecting member 74 and the sheave frame 34 are engaged detachably by a rotational center pin, and the rotational center pin is arrnged at a place, where the guide gibs 15, 17 of the lower connecting member 68 are interlinked with a guide rail when the sheave frame 34 is suspended and the upper connecting member 74 is tuned around the rotational center pin. The control levers 148, 150 of a lock pin controlling revolution are disposed at a front end on the upper connecting member 74 and the side faces of the auger drive mechanisms 18, 19. Accordingly, assembly is completed by operation, in which the auger drive mechanism is coupled by the connecting members, and assembly can be conducted easily.
