Embodiment 1

[0020] Stem and leaf vegetables of the present embodiment and the universal harvester of tea are as Figure 1 to Figure 4 As shown, the frame 4 of the channel structure is installed on the straddle crawler type walking chassis 7 driven by the walking transmission system 6, and the rear part of the frame 4 is hinged to the support arm 4- 1 rear part, both sides of the front end of the frame 4 are respectively hinged to the cylinder body of the height adjustment cylinder 5 through the J-shaped connector 5-1, and the piston rod extension end of the height adjustment cylinder 5 is in front of the corresponding support arm 4-1. Extended end hinged. A side operating system 10 is arranged on one side of the frame 4 . The loop-back conveying device 9 is composed of a driving conveying roller driven by a motor 9M, a driven conveying roller and a conveying belt (synchronous belt) looped between the two wheels, and a collecting device 8 is arranged below the output end.

Abstract

The invention relates to a universal stem and leaf vegetable and tea harvester, and belongs to the technical field of agricultural machinery. The rear part of a rack of the harvester is hinged to the rear parts of supporting arms of a loop-back conveying device; height adjustment cylinders are respectively hinged to the two sides of the front end of the rack; the stretching ends of piston rods of the height adjustment cylinders are hinged to the front stretching ends of the supporting arms; leading devices are respectively mounted on the two sides of the front ends of the supporting arms; a rotary feeding device is mounted above the part between the leading devices on the two sides; a reciprocating type cutting device is mounted at the lower rear parts, positioned between the leading devices on the two sides, of the supporting arms; mounting arms respectively stretch out the two ends of the cutting device; arc holes and round holes distributed up and down are formed in the supporting arms and are respectively used for mounting fasteners penetrating through the arc holes and the round holes. The harvester can realize precise adjustment of the cutting height in a large range, enables cutting stubble at the required cutting height to be flush and uniform, and also enables the structure to be more compact and the mechanism to be simplified, so as to conduct flexible operation in a facility greenhouse and a tea garden and meet the harvesting demands of industrial crops of the stem and leaf vegetables, the tea, Chinese wolfberry sprouts and the like.

Description

technical field [0001] The invention relates to a harvester, in particular to a general-purpose harvester for stem and leaf vegetables and tea leaves, belonging to the technical field of agricultural machinery. Background technique [0002] According to the applicant's knowledge, stem and leaf vegetables are mostly planted in facility greenhouses, and the existing stem and leaf vegetable harvesters are bulky, making it difficult to enter the shed, turn around, and work at both ends of the shed. In addition, the existing stem and leaf vegetable harvester cannot meet the harvesting requirement of low stubble because of the complicated cutting mechanism. The existing stem and leaf vegetable harvester cannot be adjusted to the height of the tea tree tea shed due to the cutting height, and lacks the cutting knife and the profiling plate leveling mechanism, so it is not suitable for tea harvesting. [0003] According to the search, the Chinese patent application with the applicat...
