[0002] Chili is a traditional industry in my country. my country is a major producer and consumer of chili, with chili cultivation distributed in 28 provinces and regions across the country, forming regional chili distribution centers represented by Guizhou, Hunan, Xinjiang and Shaanxi. With the advancement of my country's high-efficiency agriculture, the area of ​​chili cultivation has expanded rapidly, with considerable output value and benefits. However, the mechanization technology and machine research and development of chili production are lagging behind, with few varieties and poor performance, resulting in a low degree of mechanization in production, poor efficiency, high labor intensity, slow regionalization and scale development, and labor shortages in spring and autumn, which to a certain extent seriously restrict the rapid scale development of the chili industry.

[0003] The development of mechanized pepper harvesting in my country is seriously lagging behind, and pepper harvesting is basically done manually. Although some farmers have developed some machines on their own, these machines mostly cut peppers with vines and then separate the fruit and vines, making it impossible to carry out large-scale field harvesting. With the rapid expansion of pepper planting areas and the rapid increase in labor costs since 2005, the demand for mechanized pepper harvesting has become more and more urgent.

[0004] At present, there are more than 30 varieties of peppers in my country, with different appearances and characteristics. The toughness of the pepper skin is different when mature, which makes mechanized harvesting difficult; the pepper planting patterns are diverse, and the planting patterns of different regions and different varieties in the same region are different. It is mainly manifested in differences in row spacing, plant spacing, ridge height, etc.; although the current pepper harvester can complete large-scale picking tasks, there are still some problems, such as high breakage rate, high impurity rate of peppers after picking (seedling stems), strict requirements on maturity, and poor automation level and comfort of domestic models. Foreign research on pepper harvesters began as early as the middle of the 20th century, and more than 200 pepper harvesters have been designed and produced worldwide. The United States, Australia, Bulgaria, Hungary, Israel, Italy, the Soviet Union and other countries have conducted corresponding research on pepper harvesting. These countries have tested and studied 30 different pepper harvesters with different picking principles, but have not achieved good commercial harvesting results. Therefore, it is of great significance to promote the innovation and improvement of pepper harvesters. Utility Model Content
