According to the knowledge of the applicant, most of stem and leaf vegetables are planted in the facility greenhouse, and the existing stem and leaf vegetable harvester is difficult to enter the greenhouse, difficult to turn around and difficult to operate at two ends of the greenhouse due to large volume. In addition, the existing stem-leaf vegetable harvester cannot meet the harvesting requirement of low stubble cutting because the cutting mechanism is complex. The existing stem and leaf vegetable harvester is not suitable for harvesting tea because the cutting height can not be adjusted to the height of a tea shed of a tea tree and a cutting knife and a profile plate leveling mechanism are lacked.
The retrieval shows that the Chinese patent application with the application number of 201510839456.1 discloses a self-propelled leaf vegetable harvester, which comprises a frame provided with a chassis travelling mechanism, a power system, a band saw type cutting device, a conveying device and a driving control platform, wherein the rear end of the conveying device is hinged on the frame through a transverse pin shaft and a longitudinal pin shaft, the self-propelled leaf vegetable harvester also comprises a supporting device arranged below the front part of the conveying device, the supporting device consists of a profiling roller, an adjusting oil cylinder, a connecting plate and a fixed supporting arm, the profiling roller is hinged at one end of the fixed supporting arm through the connecting plate, one end of the adjusting oil cylinder is hinged on the connecting plate, and the other end of the adjusting oil cylinder is hinged at the other end. Although the belt saw type cutting device has the advantages of avoiding direct contact between the belt saw type cutting device and soil, ensuring the harvesting quality and the like, the conveying device is arranged at the front end of the chassis travelling mechanism, is long in front extension and not compact in structure, and the harvesting height is adjusted by the adjusting oil cylinder, so that the cutting height of the tea tree tea shed cannot be reached. In addition, the cutting device of this patent lacks cutting knife levelling mechanism, when adjusting the header preceding cutting knife to certain cutting height, can appear the cutting knife and rectangular pieces of land in a field or tea canopy nonparallel and lead to cutting crops irregularity, cut tender leaf or cut soil scheduling problem.
