摘要： The present disclosure relates to a backhoe loader for efficient digging. The backhoe loader includes: a vehicle body, including a first vehicle body and a second vehicle body which are connected sequentially; a loading device, arranged on the first vehicle body; a control platform, arranged on the second vehicle body and configured to rotate by 360° relative to the second vehicle body; a cab, arranged on a first side of the control platform; and an excavating device, arranged on a second side of the control platform opposite to the first side, the excavating device being configured to rotate by 180° relative to the cab. The backhoe loader can realize functions of 360° excavating and bidirectional driving. When the excavating device works, the backhoe loader can be directly moved by folding stabilizers and without changing the position of a seat back and forth, so that the excavating efficiency is improved; and an operator in the cab has a wide field of view, operation feeling is good, the backhoe loader has a compact structure, and the stability of the machine body is high.
