A harvesting device and method for pipe-cultivated leafy vegetables

Abstract

The invention discloses a pipeline cultivation leaf vegetable harvesting device and method. The device is provided with a connected pipeline conveyor and a cabbage conveyor, and the junction of the pipeline conveyor platform and the cabbage conveyor platform is provided. There are at least one set of grasping manipulators and at least one set of undercutting mechanisms. One side of the grasping manipulator is provided with a vegetable root recoverer, and the cultivation tank is transported by a pipeline conveyor. Two sides of the pipeline conveyor are symmetrically equipped with two righting and positioning leaf vegetables. The guiding and positioning mechanism used is arranged in front of the grasping manipulator along the conveying direction of the cultivation tank. The method is that the cultivation trough with leafy vegetables is continuously transported by the pipeline conveyor, and the leafy vegetables are first positioned by the guiding and positioning mechanism, and then the leafy vegetables are clamped by the grasping manipulator, and the root cutting mechanism is used to cut and separate the separated leaves. The vegetable sprouts are sent out by the vegetable sprouts conveyor, and the rhizomes and roots fall into the vegetable root collector for collection. The invention can better realize the high-efficiency and damage-free harvesting of the tube-cultivated leafy vegetables.

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
