Description

Technical Field

[0001] The utility model relates to the technical field of cotton picking equipment, in particular to a hybrid power cotton picker. Background Art

[0002] As the demand for cotton in domestic and foreign markets continues to expand, the country attaches great importance to the development of agricultural machinery (agricultural machinery). The demand for cotton pickers in the agricultural machinery market continues to expand, and the performance of cotton pickers has become the biggest competitive advantage in the market.

[0003] At present, cotton pickers at home and abroad completely rely on fuel engines to provide power during the moving operation process. Due to the heavy weight and load capacity of the cotton pickers themselves, strong power support is required during the moving operation, which consumes a lot of fuel and produces high engine noise. Moreover, when the internal combustion engine is started, it takes a certain amount of time for the fuel to ignite and fully burn, resulting in a long starting time for the cotton picker.

[0004] At the same time, the country's requirements for vehicle emission standards are constantly increasing, and the introduction of new energy technologies in the agricultural machinery field will become a major trend in the future development of agricultural machinery. In recent years, oil-electric hybrid (oil-electric hybrid) has developed rapidly in the automotive field, and the application of oil-electric hybrid technology in the automotive field has gradually stabilized, but this technology has not yet been applied in the cotton picker industry. In the existing technology, there are a small number of cotton pickers that use new energy such as solar energy and lithium batteries as power sources. In theory, although new energy can solve the problems of fuel consumption and pollutants, in actual application, new energy is greatly affected by external environmental factors and cannot provide continuous power for cotton pickers, affecting cotton harvesting.
