The traditional method of picking dried fruit is manual picking. At present, the method commonly used in domestic dried fruit picking is the "stick beating method" to complete the harvest at one time. This method is labor-intensive, dangerous, labor-intensive, low-efficiency, and high-cost. It is especially dangerous to pick dried fruits such as walnuts that grow in the mountains. Also there is easy damage branch bud in this method, destroys tree vigor, affects problems such as next year's output.

In order to improve work efficiency, a "vibration picking machine" is disclosed in the Chinese patent specification, and the patent number is "200820135334. Instead of knocking with a pole, you still have to touch the upper part of the tree little by little with your hands, and the length of the pole is fixed, and the picking height is limited, so its picking work efficiency is still not high.

Another example is that the Chinese patent specification also discloses a "vibrating fruit tree harvester", whose patent number is "200820125040.9". This vibratory fruit tree harvester consists of a fruit tree shaking device, a hydraulic control system, a fuel tank and a counterweight Composition, the fruit tree shaking device is installed on the front end of the tractor not less than 44kw, including the left and right side brackets, the main beam frame, the telescopic support arm, the vibrating head suspension frame and the clamp type vibrating head, and the hydraulic control system is installed on the fruit tree shaking device On the right side bracket, the tractor driver can reach a position where the fuel tank and counterweight are mounted behind the tractor at three points. Although one person can operate the machine, it has good maneuverability and fast fruit picking speed, and the mechanical vibration of the harvester will not damage the trees. Effective mechanical operation replaces labor, thereby saving labor and improving harvesting efficiency. However, this machine is composed of fruit tree shaking device, hydraulic control system, oil tank and counterweight. Not only is the mechanical structure complicated, but the manufacturing cost is high. Each design requires a large working space, and it is only suitable for fruit picking with large working space around the fruit tree. .

Domestic patent discloses a kind of "forest fruit picking machine", patent No. 201010278963.X. This picking machine includes mobile walking device, power supply, picking lifting device, folding extension rod, gas station, vibration picking device. The vibrating picking device of this picking machine can hold fruit trees of different positions and distances and different heights. It adopts a crawler-type walking device, which is suitable for harvesting forest fruits in hilly areas, especially for soil work surfaces with large slopes in mountain roads. Flexible maneuverability, high work efficiency, small working space requirements, and high harvesting efficiency. But its occupied area is bigger, is not suitable for the plucking of dried fruit orchards such as hillside.

There is a domestic patent disclosure of "a tree-climbing type pecan picking robot", the patent number of which is 201110377079.6. This hickory picking robot includes a tree climbing mechanism, a mechanical arm and an end effector. After the mechanical arm is positioned so that it is within a certain distance in front of the picked fruit, the action of the mechanical arm is stopped. Start the executive motor, the motor drives the crank to rotate, and the scissors are closed through the crank slider mechanism to cut off the hickory. The hickory nuts fall into the collection box under the action of their own weight. This picking robot has complicated structure, low efficiency and is not suitable for large-scale walnut grove picking.
