Therefore, there are higher requirements for the picking method of Camellia oleifera.

[0003] For example, a small self-propelled oil-tea fruit picking machine described in "CN112219554B" includes a traveling vehicle, a lifting frame, an adjusting mechanism, a rubber roller assembly and a picking head; the lower end of the lifting frame is hinged to the front end of the traveling vehicle, and its upper end can be lifted up and down relative to the traveling vehicle; the adjusting mechanism is installed on the traveling vehicle and the lifting frame, which connects the lifting frame near the lower end and is used to drive the upper end of the lifting frame to lift up and down; the rubber roller assembly is rotatably installed at the bottom of the upper end of the lifting frame, and is used to transport the oil-tea fruit branches to be picked toward the upper end of the lifting frame; the picking head is rotatably installed at the top of the upper end of the lifting frame, and the picking head continuously swings back and forth to the left and right sides while rotating, thereby jamming the oil-tea fruit on the branch transported by the rubber roller assembly and causing the oil-tea fruit to fall off the branch. The picking machine can synchronously avoid branches and flower buds to complete the reliable picking of oil-tea fruits. It is small in size and simple in structure. It is suitable for fruit picking operations with dense fruit trees and complex terrain.

[0004] However, in the prior art, a ground-mobile robotic arm is usually used, as shown in the above-mentioned patent, which extends into the tree crown through a telescopic arm or articulated arm structure to complete the picking. However, this method is not suitable for terrain such as wetlands or slopes. It is difficult to move, which affects the picking coverage rate. In addition, the length of traditional robotic arms is limited. If the crown of the fruit tree is large, it may be difficult to reach the fruits at a higher position. During picking, it is necessary to move the vehicle body on the ground to continuously adjust its position. Only after it is adjusted to the appropriate position can the robotic arm be stretched to the appropriate position. If the ground is uneven, the movement of the vehicle body will increase the preparation time before picking. In addition, if the wheels of the vehicle body roll back and forth near the fruit tree, it may also cause damage to the roots and soil of the fruit tree. Summary of the Invention

If there are many fruits on the fruit tree and they are distributed more densely, they can be picked from the upper and lower positions respectively. First, the picking arm 415 is extended to the top of the tree crown, and the picking head 417 is moved to the fruit and picked according to the drive adjustment of the arm mechanism. The picked fruit falls into the slide 5, and the fruit slides smoothly to the ground in the slide 5 for collection. If the fruit below is to be collected, the support arm 413 can be extended to the trunk, and the trunk is clamped by the clamping seat 414, and the end face of the support arm 413 is separated from the clamping seat 414. The holding seat 414 and the picking arm 415 are independently arranged on the tree trunk. By independently controlling the position of the picking head 417 on the end face of the picking arm 415, it is moved close to the fruit for picking. According to needs, the clamping seat 414 can also move up and down on the tree trunk so that the picking arm 415 can pick the fruits on the fruit tree in all directions. Through the provided end ring 416, the picking arm 415 can slide on the end ring 416 to avoid the trunk from hindering the picking effect. This method can be used to operate fruit trees with densely distributed fruits, and the picking is carried out from the outside of the fruit tree to avoid the situation where violent picking causes branch breakage as much as possible. The arm mechanism is slidably set on the rope 2, which makes the mobile picking more stable. The sling system reduces the repeated movement time of the ground arm mechanism, so that the arm mechanism can be quickly positioned and continuously picked. In addition, the arm mechanism and the picking machine do not directly contact the ground, avoiding damage to the roots of the fruit trees and the ground soil. It is suitable for wetlands, slopes and other terrains.
