Stem cutting device for crops such as onions and garlic

Abstract

The invention relates to a stem cutting device for crops such as onions and garlic. The stem cutting device comprises a frame and further comprises a posture adjusting and conveying mechanism mountedon the frame. The posture adjusting and conveying mechanism comprises at least one pair of rolls horizontally mounted on the frame. The outer circumferential surface of each roll is wound with a set of elastic rubber strips arranged axially spaced and arranged in the spiral feed direction. Each pair of rolls rotate in the opposite direction from outside to inside, and the spiral directions of theelastic rubber strips are opposite. The stem cutting device is an innovative design combining the problems existing in the existing harvesting equipment in practice, and overcomes the shortcomings ofsingle function and poor performance of the current equipment. The stem cutting device can achieve stem cutting operation of different crops such as the onions and the garlic by adjusting and replacing the spiral pitch of the stem cutting mechanism, the spiral roller diameter, the elastic rubber strips, fruit dividing folding plates in different bending and main working parameters according to thephysical size and the physical property difference of the onions and the garlic.

Description

technical field [0001] The invention relates to a device for cutting stems of onion and garlic crops, in particular to a device for cutting stems and roots of onions and garlic, belonging to the field of agricultural machinery. Background technique [0002] my country's garlic and onion planting areas are widely distributed and the geographical environment is complex. Although large-scale planting has occurred in many places, the vast rural areas are still dominated by decentralized small-scale production methods; onions, garlic and other massive root crops have common characteristics. In the ground, the rhizome is used as an edible part, and the root system is located under the rhizome. The seedlings above are longer and the roots will attach more soil. When harvesting, it is necessary to remove the soil, remove the seedlings and cut the roots. At present, the harvesting of garlic and onions is mainly done manually. Traditional methods such as planing, picking up and shaking...

AI Technical Summary

Problems solved by technology

At present, the harvesting of garlic and onions is mainly done manually. Traditional methods such as planing, picking up soil, and cutting stems are labor-intensive, easy to damage fruit, and extremely low production efficiency.

[0003] At present, researches on harvesters for lumpy rhizomes such as onions and garlic are gradually released in the market, but domestic research started late, the mechanical function is relatively single, the efficiency is low, and most of the harvesters are still in the state of semi-mechanized operation. Problems such as uneven length, high rate of fruit damage, and easy breaking of stems and seedlings
