Universal stem and leaf vegetable and tea harvester

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...

Problems solved by technology

Although the invention has the advantages of small volume and low cost of the cutting device, and the ability to harvest vegetables of different heights through adjustment, the drive mechanism of the belt-shaped toothed cutter is complicated, the adjustment of the cutter is inconvenient, and the belt-shaped toothed cutter is prone to appear. Transmission slipping, breakage, wear and other phenomena have extremely high requirements on the elasticity, wear resistance, and strength of the cutter material, and it is difficult to ensure that the cutting stubble is even and the height of the stubble is consistent through adjustment.
