All-terrain automatic tree planting machine

The invention provides an all-terrain automatic tree planting machine which comprises a crawler chassis, a cab, a water tank and a double-section mechanical arm are sequentially arranged on the crawler chassis, a planting device is hung at the tail end of the double-section mechanical arm, the planting device comprises a seedling barrel and a steel flushing pipe arranged on the seedling barrel, and the seedling barrel is connected with the water tank. The steel flushing pipe is connected with the water tank and forms planting holes in soil through a water source in the water tank, and seedlings in the seedling barrel are planted in the planting holes through the seedling barrel. The crawler chassis is adopted and matched with the cab to form the tree planting equipment in a crawler mode, the defect that large planting equipment cannot normally walk and work in desert abdominal moving dunes and hilly areas is overcome in a crawler walking mode, all-terrain tree planting work is achieved, and meanwhile the work
