Bionic type onion harvesting device

Abstract

The invention discloses a bionic type onion harvesting device, and belongs to the technical field of agricultural machinery. The disadvantages of an existing onion harvesting device of being high in power consumption, low in digging rate, severe in fruit damage and the like are overcome. The bionic type onion harvesting device comprises a soil loosening device, a leaf separating device, a leaf pulling device, a front part clamping conveying device, an onion bulb neatening device, a height adjusting device, a rear part clamping conveying device, a cutting device and an onion bulb collecting device. When in work, the leaf separating device separates non-aligned onion leaves, the soil loosening device loosens soil at the same time, under the action of the leaf pulling wheel, the whole onions enter the front part clamping conveying device, are conveyed backwards to the onion bulb neatening device, and continues to be conveyed backwards after the lower surfaces of the onion bulbs are kept identical, under the action of the rear part clamping conveying device and the cutting device, the onion bulbs are cut and fall into the onion bulb collecting device, and the onion leaves fall backwards into land. The bionic type onion harvesting device can simulate the processes of digging, flattening, leaf removing, collecting and the like when onions are manually harvested, the cost of manual harvesting can be reduced by a large margin, and the efficiency of harvesting the onions can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bionic onion harvesting device. Background technique [0002] In recent years, my country's onion industry has developed rapidly, and its planting area and output have ranked among the top in the world. However, there are few studies on onion harvesting machines, and the special onion harvesting machines suitable for my country's onion planting conditions are almost still blank. At present, there are mainly the following methods for onion harvesting: 1) Users who plant in a small area completely use manual harvesting, expensive labor increases the cost of onion planting, and the operation efficiency is extremely low; 2) Users who plant in a large area use machinery The method of combining excavation with manual sorting and processing has improved the mechanization of onion harvesting to a certain extent, but non-specialized onion harvesting machinery...

Problems solved by technology

However, there is still little research on onion harvesting machines, and the special onion harvesting machines suitable for my country's onion planting conditions are almost still blank.

At present, there are mainly the following methods for onion harvesting: 1) Users who plant in a small area completely use manual harvesting, expensive labor increases the cost of onion planting, and the operation efficiency is extremely low; 2) Users who plant in a large area use machinery The method of combining excavation with manual sorting and processing has improved the mechanization of onion harvesting to a certain extent, but non-specialized onion harvesting machinery has problems such as high energy consumption and poor operation results, and manual participation still accounts for the majority. To a large extent

The degree of research on onion harvesting machinery at home and abroad is different. There have been relatively mature models abroad, including South Korea and Canada, but the prices are relatively expensive. Some models have also appeared in China, but their adaptability is poor, especially unsuitable. The use of small area planting users
