Title: Working equipment of hydraulic back hoe
Inventor: KOBAYASHI TAKESHI
IPC: E02F3/38
Filed: 1994-10-27
Abstract: PURPOSE:To enhance the performance of equipment by elongating an auxiliary cylinder in conformity with the elongation of an arm cylinder and enlarging a rotary angle of an arm, increasing a rotary force of the arm so as to sharpen its edge force, and widening a working area. CONSTITUTION:When a cylinder 4 is elongated, a link 10 is rotated so that an arm 2 may be rotated. Then, a cylinder 11 is also elongated in conformity with the elongation of the cylinder 4 since a head-side oil chamber of the cylinder 4 is connected to a bottom-side oil chamber of an auxiliary cylinder 11 with a hydraulic circuit, thereby amplifying the rotary angle of the arm 2. As a specified rotary angle of the arm 2 is available even when the changes in the rotary angle of the link 10 is small, a rotary moment radius will be enlarged so that the edge force of a bucket will be increased. When the stroke of the cylinder 4 is reduced, the stroke of the cylinder 11 will be reduced as well, thereby widening a conventional working area on a higher angle side of the cylinder 4. This construction makes it possible to enhance work efficiency dramatically.
