Pipeline cultivation leafy vegetable harvesting device and method

Abstract

The invention discloses a pipeline cultivation leafy vegetable harvesting device and method. The device is provided with a pipeline conveyor and a flowering Chinese cabbage conveyor which are connected; at least one group of grabbing manipulator and at least one group of root cutting mechanism are arranged at the joint of a conveying platform of the pipeline conveyor and a conveying platform of the flowering Chinese cabbage conveyor; vegetable root collectors are arranged at one sides of the grabbing manipulators; a cultivation tank is conveyed by the pipeline conveyor; two guide positioning mechanisms for righting and positioning leafy vegetables are symmetrically arranged at the two sides of the pipeline conveyor; and the guide positioning mechanisms are arranged in front of the grabbingmanipulators in the conveying direction of the cultivation tank. The method includes the steps of continuously conveying the cultivation tank with the leafy vegetables by the pipeline conveyor; righting and positioning the leafy vegetables by the guide positioning mechanisms firstly; then clamping the leafy vegetables by the grabbing manipulators; cutting and separating by the root cutting mechanisms; conveying out the separated flowering Chinese cabbage by the flowering Chinese cabbage conveyor; and collecting rhizomes and roots falling into the vegetable root collectors. According to the pipeline cultivation leafy vegetable harvesting device and method, efficient and damage-free harvesting of the pipeline cultivation leafy vegetables can be well achieved.

Description

technical field [0001] The invention relates to the technical field of harvesting hydroponic leafy vegetables, in particular to a harvesting device and method for pipe-cultivated leafy vegetables. Background technique [0002] People in our country have a very large consumption demand for leafy vegetables in their daily diet, and the output of leafy vegetables accounts for about 1 / 3 of the total vegetable output. Hydroponic leafy vegetables have the advantages of rich nutritional value, short production cycle, year-round harvest, cleanliness, safety and high economic benefits, and have become the mainstream model of leafy vegetable cultivation in developed countries such as Europe and the United States. With the increasing demand of Chinese consumers for high-quality, green and pollution-free vegetables, the production scale of hydroponic leaf vegetables in my country has developed rapidly in recent years. [0003] The size and posture of each leafy vegetable growing in the...

Problems solved by technology

[0005] However, the leafy vegetable harvesting devices disclosed in the above-mentioned publications share the following problems in actual use: usually the edible stem part of the leafy vegetable is clamped, which easily damages the outer stems and leaves of the leafy vegetable, reducing the economic value of the leafy vegetable ;Leafy vegetable removal and root cutting are complicated, and the harvesting efficiency is low; harvesting operation conditions and action requirements are different from harvesting leafy vegetables from the cultivation pipeline, and it is difficult to adapt to the leafy vegetables with different shapes, sizes and poses in the cultivation pipeline
