Device and method for continuous harvesting of whole green leafy vegetables

Abstract

The present invention relates to a reaping apparatus and a reaping method for continuously reaping whole plants of green vegetables. The reaping apparatus comprises a machine frame, a crop divider, a ripper, a clamping, pulling and reversing apparatus, a root cutting apparatus, a transport apparatus, a lifting apparatus, and a walking apparatus. The crop divider is used for dividing and lifting green vegetables in a harvest area; the ripper is used for ripping a soil at roots of the green vegetables that are gathered together by the crop divider; the clamping, pulling and reversing apparatus is used for clamping and pulling the green vegetables that are gathered together, and reversing the green vegetables during a clamping and conveying process; the root cutting apparatus is used for stably and regularly cutting roots of the green vegetables during a clamping and delivering process; the transport apparatus is used for transporting the green vegetables that are pulled out; the lifting apparatus is used for supporting the clamping, pulling and reversing apparatus, and adjusting a height of the clamping, pulling and reversing apparatus from the ground; and the walking apparatus is used for driving the machine frame to walk in the harvest area. According to the reaping apparatus and reaping method provided by the present invention, a pulling method with flexible belts parallel processing is adopted to continuously reap the whole plants of green vegetables; a flexible material is adopted to avoid damage to stems or leaves; and adaptability to vegetable harvest is good.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to an orderly harvesting device and a harvesting method of green leafy vegetables, in particular to a whole plant orderly harvesting operation suitable for fresh green leafy vegetables. [0002] technical background [0003] Residents of our country love green leafy vegetables, and there is a saying that "if you don't eat green vegetables for three days, you will see gold stars in your eyes". Green leafy vegetables refer to fast-growing vegetables with fat and tender leaves and petioles as edible parts. They are an important source of nutrition. The annual balanced supply of leafy vegetables is one of the important symbols reflecting the quality of life. Green leafy vegetables are planted in multiple stubbles, and are eaten fresh and cannot be stored and transported, so they must be produced mainly in the suburbs of the local area. Therefore there is an urgent need to develop gr...

Problems solved by technology

[0004] After searching the literature of the existing technology, it was found that the Chinese invention patent "green vegetable harvester" patent application number 201110260154.0 and the invention patent "on-orbit self-propelled harvesting device and harvesting method of a facility leaf vegetable harvesting robot" patent Application No. 201510028490.0, green leafy vegetables are harvested by stubble cutting and disorderly harvesting. This harvesting method has the following problems: ① Stem and leaf stubble cutting increases the probability of microbial contamination and reduces shelf life. Higher requirements will greatly increase the comprehensive production cost; ②The residual rate of stems and leaves is too high, the loss is too large, and there are harmful organisms in the residues that need to be treated intensively, otherwise they will infect the next crop; Ye disorderly sales, this sales method is easy to accept abroad, but it is not suitable for the purchasing habits of domestic people
