Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a harvesting device for efficiently harvesting double-row sea buckthorn fruit branches. Background Art

[0002] Seabuckthorn is an important plant with high economic and ecological value. It mainly grows in arid and semi-arid areas in northern my country. Its fruit is rich in various functional ingredients, such as vitamin C and flavonoids, and is widely used in food, medicine, health products, cosmetics and other fields. In addition, seabuckthorn also plays an important role in ecological projects such as soil and water conservation and desertification control. Therefore, improving the harvesting efficiency of seabuckthorn fruit is of great significance to the sustainable development of the seabuckthorn industry and the high-quality development of the ecological economy.

[0003] However, the existing sea buckthorn fruit harvesting technology still mainly relies on traditional manual picking or mechanical vibration devices. Although manual picking can better protect the fruit, it is labor-intensive and inefficient. Especially during the period when sea buckthorn fruits are concentrated and ripe, manual picking often cannot meet the large-scale harvesting needs due to insufficient manpower. In addition, with the rising labor costs and the shortage of labor resources, the traditional manual picking method is difficult to adapt to the needs of modern agriculture for efficient harvesting and large-scale production.

[0004] Some regions have tried to improve harvesting efficiency by using mechanical vibration devices, but because sea buckthorn fruits are firmly attached to branches, the effect of vibration is limited, the fruits cannot be effectively removed, and may damage the tree and branches, thus affecting the growth and yield of the next year. The fruits that fall off are often scattered on the ground, which is easily contaminated, and the subsequent collection work is cumbersome and inefficient. Therefore, the existing mechanical vibration harvesting method has great limitations and cannot meet the needs of large-scale and efficient harvesting.

[0005] In some areas, the pruning harvesting method is adopted, that is, the sea buckthorn branches with fruit branches are cut off as a whole, and then the fruits are peeled off. Although this method improves the harvesting efficiency to a certain extent, most of the existing pruning equipment is suitable for single-row operations and cannot cover large areas of sea buckthorn planting areas. Especially in parks with large sea buckthorn planting scales, the existing equipment cannot meet the needs of efficient harvesting. In addition, the cut branches still need to be manually carried and collected, the degree of mechanization is low, and the harvesting process is time-consuming and labor-intensive, which increases labor costs and production costs.

[0006] At present, most traditional equipment or manual picking methods can only adapt to single-row operations and are difficult to achieve double-row harvesting. In large-scale seabuckthorn planting areas, there is an urgent need for a harvesting device that can efficiently cover double-row operations to improve operating efficiency, reduce manual intervention, and reduce labor intensity, thereby meeting the urgent needs of modern agriculture for efficient and large-scale harvesting.

[0007] Based on the above situation, the efficient double-row seabuckthorn fruit branch harvesting and picking equipment of the present invention came into being. Through innovative design, it solves multiple problems existing in the prior art, especially the problems of low efficiency, high labor intensity, and the inability of the equipment to cover large-scale planting. The equipment harvests seabuckthorn fruit branches on both sides at the same time, which not only greatly improves the harvesting efficiency, but also significantly reduces the dependence on manual labor, and meets the demand for efficient harvesting under large-scale planting conditions. Through the coordinated operation of various devices, the present invention can effectively cover double-row operations, improve operating efficiency, reduce manual intervention, reduce labor intensity, and realize an efficient and mechanized harvesting process.

[0008] This innovative design concept provides strong support for the mechanization and modernization of the sea buckthorn industry and further promotes the development of sea buckthorn harvesting technology. Summary of the invention

[0009] In view of the problems of low efficiency, high labor intensity and insufficient equipment coverage in the existing sea buckthorn fruit harvesting technology, the present invention provides a harvesting device for efficient double-row sea buckthorn fruit branch harvesting. The device is designed to significantly improve the harvesting efficiency and reduce the labor intensity of manual labor through the organic cooperation of the harvesting device, the conveying device, the walking device and the folding device. Specifically, the harvesting device picks the sea buckthorn fruit branches from the tree body through the cutting system and the branch-pushing mechanism, and the picked sea buckthorn fruit branches are smoothly transported to the sea buckthorn storage vehicle through the conveying device. The left and right harvesting devices are adjusted in position through the hydraulic system and connected to the conveying device. The cutting system and the branch-pushing mechanism are driven by the motor to harvest on both sides at the same time, which greatly improves the working efficiency. The walking device drives the entire device to travel in the sea buckthorn planting area, and the angles of the harvesting device and the conveying device are flexibly adjusted through the hydraulic system to adapt to different planting row spacings. The design of the folding device enables the device to be folded to a compact size in a non-working state, which is convenient for transportation and storage, and can be effectively unfolded in a working state to cover a larger harvesting range.

[0010] In order to further improve the harvesting efficiency and reduce the mechanical burden of the equipment, the present invention specially designs an "S-shaped" route harvesting method. Through this design, the equipment can flexibly travel between multiple rows of sea buckthorn trees, ensuring that the harvesting device can cover the entire operating area and complete efficient double-row harvesting. After the equipment completes the harvesting of two rows of sea buckthorn fruit branches, the storage vehicle is replaced by simple adjustment to ensure the efficient cycle of the harvesting process. In addition, the angles of the harvesting device and the conveying device of the equipment can be flexibly adjusted to meet the needs of different sea buckthorn planting row spacings. The "S-shaped" route not only reduces the turning and repeated driving of the equipment, but also improves the operating efficiency, while reducing the mechanical burden and enhancing the stability and safety of the equipment. Overall, the present invention successfully solves the problems of low harvesting efficiency and high labor intensity in the prior art through the clever coordination between the various devices and the special harvesting method, meets the needs of modern agriculture for large-scale sea buckthorn planting, and promotes the mechanization and modernization of the sea buckthorn industry.

[0093] According to the hydraulic principle, when working, by controlling the first manual three-position four-way reversing valve 1101, the hydraulic oil can be further controlled through the throttle valve 1102 to extend, retract and neutral state of the ninth hydraulic cylinder 0601. When the second manual three-position four-way reversing valve 1103 is controlled to be in the right position and the manual two-position four-way reversing valve 1107 is in the left position, the hydraulic oil flows into the synchronous motor 1105 through the one-way throttle valve 1104, and the synchronous motor 1105 controls the hydraulic oil flow in the two branches to be the same, and further transports it to the internal leakage liquid control one-way valve 1106, and the first hydraulic cylinder 0202 and the second hydraulic cylinder 0205 perform the same extension movement synchronously, and the hydraulic oil at the piston rod end flows back to the second manual three-position four-way reversing valve 1103 and then to the hydraulic oil tank 0701; when the second manual three-position four-way reversing valve 1103 is controlled to be in the left position and the manual two-position four-way reversing valve 1107 is in the right position, the hydraulic oil flows through the manual two-position four-way reversing valve 1104 to the synchronous motor 1105, and the synchronous motor 1105 controls the hydraulic oil flow in the two branches to be the same, and further transports it to the internal leakage liquid control one-way valve 1106, and the first hydraulic cylinder 0202 and the second hydraulic cylinder 0205 perform the same extension movement synchronously, and the hydraulic oil at the piston rod end flows back to the second manual three-position four-way reversing valve 1103 and then to the hydraulic oil tank 0701; when the second manual three-position four-way reversing valve 1103 is controlled to be in the left position and the manual two-position four-way reversing valve 1107 is in the right position 07 flows to the internal leakage hydraulic control one-way valve 1106, and the internal leakage hydraulic control one-way valve 1106 will be able to realize reverse flow.
