[0037] The working principle of the digging ginger harvesting device of the present invention is as follows:

[0038] The mobile platform is used to move the device, the soil shaking and cutting module is used to screen and cut the ginger pieces, the digging module is used to dig the ginger pieces, the rice-supporting module is used to support the rice, and the collection module is used to collect the ginger pieces; when the mobile platform moves, the shovel is subjected to the pressure of the soil layer and rotates with the support as the rotation center, and vibrates through the self-excited vibration device to reduce the digging resistance and improve the digging efficiency. When the tillage layer in the rice-supporting module begins to decrease, the reset spring pushes the rotating transmission plate, the contoured slide plate rotates, the rice-supporting device electric push rod extends, and the rice-supporting device is lowered, which is conducive to achieving adaptation to the terrain and reducing the loss rate and damage rate of ginger. Under the action of the rice-supporting device, the ginger seedlings enter between the two clamping belts, and the soil shaking belt is used to shake the soil and transport it. When the brush device is transported, the brush can drive the motor to drive the lead screw through the clamping roller device to achieve a flexible brush spacing, and the brush drive motor drives the flexible brush to clean the mud. When it is transported to the cutting and separation device, the ginger and the stem are cut and separated, and the ginger falls into the soil shaking screen to screen the soil again. After the soil shaking screen falls into the conveyor belt, the belt transmission mechanism drives the motor to provide driving force to drive the conveyor belt collection box. When the collection box on one side is full, the belt transmission mechanism drives the motor to drive in the opposite direction to transport the soil to the collection box on the other side, thereby improving the harvesting efficiency and reducing the labor intensity of farmers.
