The traditional red date harvesting method comprises rod striking harvesting and semi-mechanized equipment harvesting. The rod striking harvesting has better continuity, but has higher manpower demand and lower harvesting efficiency, is easy to damage the branches of the jujube trees and the red jujubes, is not beneficial to the growth of the trees, and also influences the quality of the red jujubes. Semi-mechanized equipment is mainly used for picking manually by utilizing some semi-mechanized equipment, such as a lifter, a ladder and the like, so that the picking efficiency is low.

In order to solve the problem that the traditional red date harvesting mode is low in efficiency, a cover net shaking harvesting method is developed, the method is operated as shown in figure 1, when red dates are harvested, a net covers the whole crown of a red date tree, a net opening is tightly tied to the trunk of the red date tree, branches or trunks are shaken manually to enable the red dates to be separated from the branches and fall into a collecting net, and then a date leaking opening is formed in the lower end of the net to enable the red dates to be discharged.

Although the method is improved in the harvesting efficiency compared with the two traditional harvesting methods, the method still has the following defects: 1. the covering net, the taking net and the shaking of the trunk all need manual operation, and the installation and the disassembly of the collecting net are troublesome; 2. the branches are easy to hook the net opening, and the branches are easy to tear off and the collecting net is easy to tear off when the net is taken.
