Description

A garlic harvester profiling seedling cutting and flexible speed-reducing conveying device

technical field

The invention belongs to the technical field of agricultural machinery, and in particular relates to a garlic harvester profiling seedling cutting and flexible speed-reducing conveying device.

Background technique

Garlic is an important vegetable crop and economic crop in my country. For many years, China's garlic planting area and output have ranked first in the world, and now it has become the world's largest garlic producer, consumer and exporter. However, my country's garlic mechanized harvesting technology is relatively lagging behind, seriously restricting the development of the garlic industry.

Garlic is a labor-intensive cultivated crop, and harvesting is an important part of its production process. Traditional manual harvesting involves removing the stems, leaves, and roots of garlic plants to obtain bulb parts, which is labor-intensive, takes up a lot of farming hours, and is inefficient. Research institutes have developed a garlic combined harvesting prototype that can separate the stems, leaves and garlic fruit. At present, the horizontal conveying mechanism of the domestic garlic combine harvester mostly adopts the chain rod conveying mechanism, which will cause collision damage between the garlic and the chain rod, and the free fall motion of the garlic fruit in the vertical direction will make it have a large kinetic energy at the point of landing. , and then violently collide with the traditional metal rod chain conveying device, which will lead to an increase in the damage rate.

Some relatively mature production technologies and equipment in foreign countries are difficult to meet the actual needs of my country's production due to their high prices and differences in their production models and operating environments. Therefore, the research and development of an economical, practical, and efficient profiling seedling cutting and speed-reducing conveying device suitable for domestic garlic mechanized harvesting has important practical significance for accelerating the mechanized production of garlic in my country and promoting the development of the garlic industry.
