Detailed ways

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

As shown in FIGS. 1 to 5 , a bucket for trench excavation includes a bucket body 1 and an earth drilling device arranged on the bucket body 1 . The utility model focuses on improving the structure of the earth drilling device. The structure of the earth drilling device includes a driving mechanism, a transmission mechanism, a drill rod 2 and a protective plate 3 .

The driving mechanism includes a gear box 4 arranged at the edge of the arc-shaped bucket wall of the bucket body 1 and a driving motor 5 arranged on the gear box 4 . The gear box 4 is mainly used to change the output direction, so that the output shaft of the gear box 4 is close to the inner wall of the straight bucket wall, so that the driving motor 5 does not protrude outside the straight bucket wall and affect the excavation, and at the same time, it can also reduce the impact of the transmission mechanism on the shovel. The space occupied inside the bucket; the gear box 4 structurally includes two horizontally arranged and meshed gears; 10 Adjust the direction of the output shaft of the gearbox 4. The drive motor 5 is powered by a built-in battery of the forklift, and is controlled by a control switch arranged in the forklift control room.
