SHIELDING AND LOAD COLLAPSING DEVICE FOR BUCKET ELEVATOR EXCAVATOR

摘要

PURPOSE: To send bulk loads to the bucket side by preventing bulk loads difficult to be drifted from sliding down and hanging over an excavating part, preventing bulk loads to be easily drifted from flowing between buckets in the lowermost position and slitting them in moving. ;CONSTITUTION: An L-shaped frame 5 is connected to the lower end of an oscillating frame, and a bucket chain 12 is circulated into an L shape along the L-shaped frame 5, and bulk loads 14b are scraped by the bucket 12a. A supporting arm 20 is rotatably supported by a sprocket 9, and a bucket protecting plate 21 is provided on the supporting arm 20. The bucket protecting plate 21 is placed horizontally when the bulk loads 14b to be easily drifted are scraped by drive of a driving cylinder 23, and the protecting plate 21 is erected when the bulk loads difficult to be drifted are scraped. Moreover, a load collapsing blade 26 is rotatably supported to both end edges of the bucket protecting plate 21 by a longitudinal shaft 28, and also the position regulation is performed by a compression coil spring.;COPYRIGHT: (C)1995,JPO
