Description

Technical Field

[0001] This patent relates to the technical field of mechanical equipment for the management and harvesting of southern candlesticks, specifically a stretcher-type southern candlestick pruning and harvesting machine that combines pruning and harvesting functions, aiming to improve the mechanization level and operating efficiency of southern candlestick management. Background Art

[0002] Nanzhu, commonly known as the black rice tree, is an evergreen shrub belonging to the family Ericaceae. It is mostly distributed in southern my country. It is named because people use its leaves to steam black rice for consumption on the third day of the third lunar month every year. In addition, its fruit, branches, leaves, and roots all have high medicinal value. Existing Nanzhu pruning and harvesting mainly rely on manual labor, mostly using hedge pruning equipment or tea harvesting equipment, which has poor applicability, high labor intensity, and low operating efficiency. In recent years, although some tea garden pruning machines and tea picking machines have appeared, these devices often have single functions and cannot meet the needs of pruning and harvesting at the same time. For example, the existing patent (CN 118947356 A) a tea garden picking robot device and an autonomous picking operation method includes a frame, a crawler walking mechanism, a cutter, a parallel mechanical arm, a negative pressure collection device, etc. The device can only pick tender leaves on gentle terrain, but cannot harvest tender branches, and cannot harvest on steep terrain; and the traditional hedge pruning device does not have the function of harvesting, and the branches and leaves are scattered and difficult to collect. Currently, there is almost no equipment for harvesting the branches and leaves of the black rice tree. Summary of the invention

Similarly, the distance between the two can be adjusted to adapt to the harvesting of tender branches and leaves at different times.

Workers only need to carry the machine forward to complete the pruning and harvesting of the southern candle, reducing labor intensity.

[0019] (3) The cutting mechanism and the collecting mechanism are compact in structure. The collecting mechanism rolls on the top of the pruned tree and at the same time, the rotating feeding device is driven by a belt. The speed changes of the two rotations are synchronized with the speed changes of the workers' movements. The equipment is easy to operate and easy to maintain. The equipment is equipped with high-strength pruning tools and a cutting mechanism with adjustable position, which makes the pruning and harvesting process more precise and uniform. This not only improves the quality of the harvested Euphorbia obesa leaves, but also ensures the healthy growth of Euphorbia obesa trees, reduces damage to branches and leaves, promotes the normal development of Euphorbia obesa trees, and helps to increase the long-term yield of Euphorbia obesa trees.
