The invention discloses a
tree planting pit digging
machine, which includes a working platform, a hydraulic lifting arm is fixedly connected to the left side of the top of the working platform, and a first
electric motor is fixedly connected to the bottom of the hydraulic lifting arm at the end far away from the working platform. A telescopic rod, the bottom of the first electric telescopic rod is fixedly connected with a motor, the bottom of the
motor shaft is fixedly connected with a support plate, the axis at the bottom of the support plate is fixedly connected with a screw rod, and the two sides of the bottom of the support plate Both are slidably connected with a
cutting knife, and one side of the
cutting knife is fixedly connected with a second electric telescopic rod. The present invention can replace manual excavation through the cooperative use of the working platform, hydraulic boom, first electric telescopic rod, motor, support plate, screw rod,
cutting knife, second electric telescopic rod, control platform, chute and slider. For tree pits, the use of mechanized operations improves the efficiency of digging pits, saves time, reduces the labor intensity of workers and the labor cost of enterprises.
