Description

Technical Field

[0001] The present invention belongs to the technical field of leafy vegetable harvesting, and particularly relates to an experimental system and method for leafy vegetable harvesting. Background Art

[0002] With the rapid development of agricultural mechanization and intelligent technologies, the mechanized harvesting of leafy vegetable crops has become an important research direction for improving agricultural production efficiency and reducing labor costs. As one of the main leafy vegetable crops in China, Chinese cabbage has a wide planting area and high harvesting frequency. However, traditional manual harvesting has problems such as high labor intensity, low efficiency, and high costs. In response to this demand, efficient and low-loss harvesting machinery suitable for leafy vegetables such as Chinese cabbage has been developed.

[0003] When designing and developing a Chinese cabbage harvester, accurate calibration of technical parameters is crucial. Different varieties of Chinese cabbage have significant differences in plant height, leaf width, number of leaves, stem base diameter, and plant weight. These factors directly affect key parameters such as the height of the cutting device, the speed of the conveying device, and the clamping force of the harvester. If the technical parameters are set unreasonably, problems such as uneven cutting, missed harvesting, and damage to plants may occur, seriously affecting the harvesting efficiency and quality. By building a Chinese cabbage harvesting test bench, systematic parameter tests can be carried out on Chinese cabbage of different varieties and growth states to obtain accurate and reliable basic data, providing a scientific basis for the optimized design of the harvester.

[0004] In addition, during the Chinese cabbage harvesting process, collecting relevant operation information data is of great significance for improving the performance and intelligent development of the harvester. The operation information data covers multiple aspects such as the running speed of the harvester, the working status of each component, transmitted torque, and harvesting loss rate. Through real-time monitoring and analysis of these data, problems existing in the actual operation of the harvester can be detected in a timely manner, such as the damage of Chinese cabbage in each harvesting link, low power transmission efficiency, and excessive force in the harvesting process. Based on these data feedback, the structural design, power system, control algorithm, etc. of the harvester can be optimized and improved accordingly to improve the reliability, stability, and operation efficiency of the harvester, and realize precise and intelligent operation of Chinese cabbage harvesting.

[0005] The Chinese cabbage harvesting test bench, as an important technical support platform in the research and development process of leafy vegetable harvesters, plays an irreplaceable role in calibrating technical parameters and collecting operation information data, laying a solid foundation for promoting the innovative development and wide application of leafy vegetable harvesters.
