Tree-planting digging machine

The rear suspension type of the tractor digging machine is also known as the large tree-planting digging machine or the mechanical digging machine, which mainly uses the rotary shaft of the digging machine to connect the spline shaft of the tractor, and the digging machine drives the rotation for operation. Tractor belt excavator, diameter of the excavator is 60CM - 100CM, and different excavator models are configured according to the horsepower of the tractor. The suspended digging machine is composed of drive shaft, reducer, drill bit, pull rod and frame, etc. It is hung at the back of the tractor by the hydraulic suspension device, and the drill bit is driven by the power output shaft of the tractor through the transmission system for excavation, and the drill bit is also directly driven by the hydraulic motor for operation. The drill bit is generally of double screw type. Some excavators are equipped with two or more drills, weighing multi-bit excavators, which can make full use of the power of tractors and improve productivity. In order to prevent the drill bit from being damaged due to overloading when encountering stones, tree roots and other obstacles during operation, a jaw clutch is installed on the transmission shaft. In the case of overloading, the clutch automatically slides, thus cutting off the transmission of power. Due to large power and high efficiency, the hanging type pit excavator can excavate large pits, which is suitable for areas with flat terrain or where tractors can pass through. 

Application scope of tractor belt digging machine: large digging machine is applicable to digging cylindrical pit of warm soil in plain, hill, sandy land and other site conditions, and equipped with semi-loaded drill bit for hole-like land preparation, pin root removal and other operations. Widely used in large areas of fast-growing and high-yield forests, large seedlings pits and urban landscaping, suitable for returning farmland to forests, tree-planting and tree-digging, etc. The tractor with pit digging machine has reasonable drill bit structure, stable operation and high efficiency. The excavated pit wall is vertical and equipped with overload protection device to prevent damage.

Characteristics of mechanical tree-planting digging machine:

The tractor with pit digger has reasonable drill structure, stable operation and high efficiency. The excavated pit wall is vertical and equipped with overload protection device to prevent damage.

Technical parameters: tractor belt excavator, diameter of the excavator is 60CM - 100CM, and different excavator models are configured according to the horsepower of the tractor. It is convenient to use tractors of Yituo Dongfanghong - 170, 180, 200, 300, 350, 400 and Jiangxi - 180 for operation. Depth of excavation: 0-1200mm, diameter of excavation: 60CM-120CM Efficiency: 80-150 pits/hour (strong soil breaking capacity of double blade)
