Orderly harvesting and conveying device for stem leaf vegetables

Abstract

The invention relates to an orderly harvesting and conveying device for stem left vegetables. The device comprises a rack, a cutting device installed on the rack and a rotary bottom conveyor belt, wherein the front end of the bottom conveyor belt is positioned at the back of the cutting device and is inclined towards the rear upper part. The device is characterized in that the device also comprises rotary side conveyor belts installed on the rack; the side conveyor belts are symmetrically arranged above the bottom conveyor belt; a Y-shaped conveying passage with a shrinking inlet is formed bythe side conveyor belts and the bottom conveyor belt; the width of the inlet front end is the same as that of the cutting device; and the side conveyor belts and the bottom conveyor belt operate at equal linear speed. The conveying manner that the vegetables are collected in a vertical state initiatively, adjacent vegetables are clustered together to be conveyed backwards by the bottom conveyor belt and the side conveyor belts, a good and coincident vertical state can be maintained in the conveying process, the stem left vegetables can be harvested and conveyed in good order, and the device has the characteristics of simple structure and high operation efficiency.

Description

technical field [0001] The invention relates to a vegetable harvesting machine, in particular to an orderly harvesting conveying device suitable for stem and leaf vegetables, belonging to the technical field of agricultural machinery. Background technique [0002] The vast majority of stem and leaf vegetables in my country (such as green vegetables, moss, amaranth, etc.) are planted in disorder. Since there is no vegetable harvesting machinery suitable for orderly harvesting of stem and leaf vegetables, the current mechanized harvesting The method is also disorderly harvesting. Although the harvesting efficiency is improved, the quality of the stem and leaf vegetables after harvesting is different, and it increases the difficulty of post-order finishing and processing, increases the cost, and reduces the commodity value. [0003] After searching, it is found that Chinese patent No. 201410281685.1 discloses a vegetable orderly harvester, which includes a rotary belt conveying ...

AI Technical Summary

Problems solved by technology

However, practice has proved that its shortcomings are that during the transportation process of harvesting leafy vegetables, due to the sparse density of leafy vegetables (consistent with the growth density of leafy vegetables in the vegetable field), they cannot maintain a good and consistent upright state, so in The leafy vegetables at the output end will still be messy and disorderly when they fall into the vegetable collection box

However, the disadvantage of this conveying method is that the structure of the machine tool is relatively complicated, and the conveying efficiency is low.

[0005] Therefore, the harvesting delivery device of the vegetable harvester of the prior art can not be practically used for harvesting stem and leaf vegetables in an orderly manner.
