A top plate 9 is fixedly installed at the top of the support 10, and a picking component is installed at the top of the top plate 9. The picking component is used to pick the fruit in the agricultural orchard. A bottom plate 12 is fixedly installed at the bottom of the support 10, and a storage component is installed on the front side of the support 10. The storage component is used to collect and store the picked fruit.
[0032] Reference Figures 3-4The harvesting assembly includes an engine 2, a power plate 3, a support plate 4, a fixing plate 5, a cylinder 6, a mounting plate 7, and two grippers 8. The engine 2 is fixedly installed on the top of the top plate 9 to drive the harvesting assembly. The output end of the engine 2 is fixedly connected to the input end of the power plate 3. The output end of the power plate 3 is fixedly installed with the support plate 4, which serves as a transmission mechanism. The fixing plate 5 is fixedly installed on one end of the support plate 4. The cylinder 6 is fixedly installed on the bottom of the fixing plate 5. The output end of the cylinder 6 is fixedly connected to the mounting plate 7. The cylinder 6 can drive the mounting plate 7 to move up and down. Two grippers 8 are fixedly installed on the top of the mounting plate 7 to grasp the fruit.
[0033] Reference Figure 2 The storage assembly includes two side plates 14, two connectors 15, two extension arms 16, and a storage box 17. The two side plates 14 are fixedly installed in the middle of the front side of the bracket 10. Connectors 15 are fixedly installed on the front side of both side plates 14. Extension arms 16 are installed on one side of each connector 15. The extension arms 16 are fixed to the connectors 15 by screw rotation. The two extension arms 16 are fixedly installed at both ends of the top side of the storage box 17, ensuring the structural stability of the storage assembly. It can withstand a certain weight of fruit and is not easy to loosen or be damaged. The storage assembly allows the harvested fruit to be stored in the storage box 17 in a timely manner, avoiding damage caused by random placement of the fruit.

[0034] Reference Figure 2 A limiting tube 11 is fixedly connected to one side of the top of the bracket 10, and the top of the limiting tube 11 is higher than the support plate 4. The limiting tube 11 helps the bracket 10 to remain stable and can limit the rotation of the support plate 4 in the picking component.
[0035] Reference Figure 2 The four corners of the bottom of the base plate 12 are fixedly installed with fixing plates 13, and the automatic fruit picking robot arm is firmly fixed to the orchard ground by the fixing plates 13.
[0036] Reference Figure 3 A battery 1 is fixedly installed on one side of the engine 2, and the engine 2 is electrically connected to the battery 1, which ensures stable power transmission and enables power to be efficiently transmitted from the energy source to the power output components, thus ensuring the normal operation of the harvesting components.

[0038] Reference Figure 4Two grippers 8 are symmetrically distributed at the top of the mounting plate 7, which enables the cylinder 6 to precisely control the movement of the mounting plate 7 and the grippers 8, thereby achieving precise grasping and picking of the fruit and improving the success rate and accuracy of picking.
[0039] Reference Figure 2 The storage box 17 is square, which can effectively collect the harvested fruit and reduce secondary damage to the fruit. At the same time, the storage box 17 has a certain storage space, which reduces the need for frequent fruit transfer.
[0040] Working principle: The automatic fruit-harvesting robotic arm is securely fixed to the orchard ground by a fixed plate 13. The limit tube 11 and auxiliary support 10 maintain stability. The battery 1 of the harvesting component powers the engine 2, which drives the power plate 3 to rotate. The power is transmitted to the fixed plate 5 via the support plate 4. The cylinder 6 on the fixed plate 5 extends and retracts according to the control system command, driving the mounting plate 7 and the gripper 8 to move to the location of the fruit and accurately grasp the fruit. The gripper 8 places the fruit in the storage box 17 of the storage component. The side plate 14, connector 15 and extension arm 16 of the storage component work together to flexibly adjust the position of the storage box 17 to receive the fruit delivered by the harvesting component. Throughout the process, the various components of the robotic arm cooperate with each other to realize the automatic harvesting and storage of fruit, effectively improving the orchard harvesting efficiency.
