At present, the banana harvesting methods in my country are extensive, and the banana harvesting in most areas is mainly manual harvesting. However, the current method of manual harvesting is time-consuming, labor-intensive, labor-intensive, and it is difficult to prevent bananas from being mechanically damaged. It can adapt to the harvesting of small batches and low-grade bananas. Although the use of cableway transportation abroad can solve the problem of banana transportation, there are still no corresponding mature electric cutting and banana harvesting devices, and banana harvesting still remains at purely manual picking, with low efficiency. This has greatly restricted the development of the banana industry, and simply relying on manual picking can no longer meet the growing demand for bananas.
