The rotating lifting blade is fixed and positioned by the locking retainer, which can be quickly disassembled and replaced conveniently and efficiently. Different types of rotating lifting blades can be selected according to different crops, and the distance between the rotating lifting blades can be adjusted in real time according to the distance of the crop ridge, so that full freedom is realized.

[0024] The power driving unit is the main power output part, which is composed of a servo motor 6, a connecting chain 7 and a transmission sprocket 8. The servo motor is connected to the control end of the machine body. The servo motor monitors the speed and position in real time through the encoder and other sensors, and feeds back the data to the control system. The control system drives the servo motor according to the demand. The servo motor drives the lifting blade unit to work through the sprocket transmission.

[0025] The center transmission shaft 2 is provided with a shaft end bearing 3 at one end and a connecting rod 5 at the other end. The center transmission shaft 2 is fixed on the rack through the shaft end bearing 3 and the connecting rod 5.

The angle and shape of the blade can effectively capture the lodged crops during rotation, avoiding missing or damage. The lifting blade is designed to prevent entanglement. The edge is made of smooth material or special geometric shape to prevent crop residues from being stuck. The edge of the blade is made of smooth material and special geometric shape to prevent crop residues from being stuck.
