Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and relates to a control system of a double-bag fresh grape packaging and grading device. Background Art

[0002] Packaging and grading fresh grapes after harvest is a crucial step in the grape production cycle, playing a crucial role in improving grape quality and boosting the economic benefits of the grape industry. Due to their thin, juicy skin, fresh grapes are susceptible to damage from abrasion, collisions, and threshing during harvesting, packaging, and transportation due to a lack of effective protection. If not handled promptly, the grapes can become infected and spoil due to pathogens, resulting in significant economic losses. Packaging fresh grapes can maintain their quality, extend their shelf life, and increase their added value and production value. Currently, the grading and packaging process for fresh grapes is primarily performed manually by experienced workers, a method that is inefficient and labor-intensive.

[0003] Most existing fruit and vegetable packaging machines are still in the experimental stage and have not yet achieved full automation of the packaging process. Therefore, research on automatic packaging equipment for fresh grapes is of great significance. It can not only reduce labor input and costs, but also improve the degree of mechanization in my country's grape production. Summary of the Invention
