[0032] In this embodiment, the specific operation of the Evodia rutaecarpa harvesting device (i.e., this device) includes the following steps: 1) During transportation, the folding hydraulic cylinder 2-10 of the folding mechanism 2 is in a retracted state, and the device is located directly behind the tractor 1. After arriving at the work site, the device is lifted by the hydraulic system of the tractor 1, and at the same time, the folding hydraulic cylinder 2-10 of the folding mechanism 2 is extended, and the fixed frame 3-1 is driven to rotate clockwise around the rotating shaft 2-5 of the folding mechanism 2 through the folding piston rod 2-11. When the folding hydraulic cylinder 2-10 reaches the final extended position, it reaches the working state.

Since the collecting assembly 5-2 has a certain slope, the Evodia rutaecarpa fruits roll into the conveyor belt 5-1 and are finally transported to the collecting frame; Repeat step 2) to complete the harvest of the fruit of an Evodia rutaecarpa plant; 3) After the picking work is completed, the hydraulic system of the tractor 1 lifts the device, and at the same time, the folding hydraulic cylinder 2-10 of the folding mechanism 2 is retracted, and the fixed frame 3-1 is driven to rotate counterclockwise around the rotating shaft 2-5 of the folding mechanism 2 through the folding piston rod 2-11. When the folding hydraulic cylinder 2-10 reaches the final retracted position, the device reaches the transportation state. At this time, the hydraulic system of the tractor 1 is depressurized, the tire 3-11 contacts the ground, and the mounting plate 2-6 is connected to the fixed frame 3-1 through the pin shaft to fix the device to prevent the device from rotating during transportation; Repeat steps 1) to 3) to complete the transportation and harvesting work of the device.
