This invention designs a double-action cutting pepper harvesting device, driven by a motor. The peppers are fed in using the pepper-feeding wheel of the harvesting system, and the double-action cutting blades of the harvesting system cut the peppers off, which then enter the collection tube through the rear collection channel. The double-action cutting blades effectively improve the shearing force and reliability, thus increasing harvesting efficiency.
