Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, the utility model proposes an onion planting harvester, including a frame 1, a moving component 2, a multifunctional pulling component 3 and a cutting component 4. The moving component 2 is fixedly arranged on the outer wall of the frame 1, the multifunctional pulling component 3 and the cutting component 4 are respectively fixed on the inner wall of the frame 1 and the cutting component 4 is arranged below the multifunctional pulling component 3, the multifunctional pulling component 3 includes a driving component 5 and a transmission roller structure 6, the cutting component 4 includes a driving component 5 and a cutting knife 7, two groups of driving components 5 are respectively fixed on the side walls of the frame 1, and the transmission roller structure 6 and the cutting knife 7 are respectively fixed on the two groups of driving components 5.

[0023] In order to provide power for pulling out and cutting, the driving assembly 5 includes a transmission motor 8, a transmission shaft 9, a solenoid 10 and a nut slider 11. The transmission motor 8 is fixedly mounted on the side wall of the frame 1 and the output shaft runs through the frame 1. One end of the transmission shaft 9 is fixedly mounted on the output shaft of the transmission motor 8 and the other end is rotatably arranged on the side wall of the frame 1. Each group of driving assemblies 5 is provided with two groups of solenoids 10. The solenoids 10 are arranged on both sides of the transmission shaft 9, and the thread directions of the solenoids 10 are opposite.
