Background
Cabbage is one of the main varieties for vegetable planting, but the mechanization level of vegetable production is relatively laggard compared with grain production. For a long time, the harvesting of the cabbages still basically depends on manual operation, and has low labor efficiency, high labor intensity, poor operation quality and high production cost.
In recent years, the applicant and Nanjing agricultural mechanization research institute of rural agricultural department have together researched and developed cabbage harvesting machines, and designed a series of cabbage harvesting machines. Such as, for example,
the patent number 2018221709581 discloses a clamping device of a common head cabbage harvesting machine, which is applied by Nanjing agricultural mechanization research institute in 2018, 12 and 24, and is only a harvesting device in the whole machine patent, namely a header assembly disclosed in the patent application of the invention, which is a part of the whole machine and needs an integrated walking and conveying mechanism to realize the whole-process mechanized cabbage harvesting.
The patent of invention discloses a cabbage harvester (patent number 2021101436874) issued by Nanjing agriculture mechanization research institute of rural agricultural department, which consists of a traveling mechanism, a harvesting mechanism and a transmission mechanism.
