Description

Technical Field

[0001] The invention relates to the technical field of tobacco leaf picking, and more specifically to a fully automatic tobacco leaf clamping, arranging and picking vehicle. Background Art

[0002] With the continuous progress and innovation of modern agricultural technology, the tobacco planting industry has made remarkable achievements, especially in the integration and application of automation and intelligent technology. However, although many links in the overall production process have been or are being transformed into mechanization and automation, the key link of tobacco leaf picking still faces many challenges. Traditional tobacco leaf picking operations rely almost entirely on manual operations, which not only means that a large amount of labor resources are required, but also workers perform repetitive and high-intensity labor in the fields for a long time, which can easily lead to physical fatigue and affect the picking efficiency. In addition, the manual picking method is difficult to match the speed of fast-growing tobacco leaves, resulting in a long picking cycle and low overall operation efficiency.

[0003] More importantly, due to the inevitable individual differences in the manual picking process, such as different judgment standards and different techniques, the maturity, integrity and degree of damage of the picked tobacco leaves vary greatly. This inconsistency directly affects the quality control of the tobacco leaves in the subsequent processing process, which is ultimately reflected in the taste and aroma of the finished product, reducing the overall quality and market competitiveness of the tobacco leaves. At the same time, manual picking also faces the problem of rising labor costs year by year. For growers, this undoubtedly increases the economic burden and limits the further expansion of the industry.

[0004] In summary, the problems of high labor intensity, low efficiency, and difficulty in ensuring the quality and consistency of tobacco leaf picking in traditional tobacco leaf picking methods have become bottlenecks restricting the high-quality development of the tobacco leaf planting industry. Therefore, the development of a new type of equipment that can efficiently, accurately, and automatically complete tobacco leaf picking tasks can not only greatly improve picking efficiency and reduce the labor intensity of farmers, but also effectively ensure the quality of tobacco leaf picking and promote the sustainable development of the tobacco leaf planting industry. This is the focus of common concern and urgent need within and outside the industry. Summary of the invention
