[0002] Blueberry is a deciduous shrub of the Ericaceae family and the genus Vaccinium. Its scientific name is Vaccinium truncatum, commonly known as blueberry. The twigs of blueberry are green, angular or cylindrical, usually with rows of soft hairs; the leaves are nearly leathery, ovate to elliptical, with acute tips, cherry-shaped to nearly rounded bases, serrated to entire margins, and dark green; the racemes grow on last year's branches, the flowers are green and hairless; the corolla is white to pink and nearly cylindrical; the berries are spherical, dark blue, hairless, and covered with white powder. Blueberries are native to North America, especially eastern Canada and the eastern and southern United States. Blueberries like warm climates, are resistant to high temperatures, like semi-sunlight environments, and humid environments. They are suitable for growing in fertile, loose, and organic-rich acidic soils. Blueberries have extremely high nutritional value and are rich in flavonoids, vitamin C, vitamin K, vitamin A, and minerals such as potassium, manganese, calcium, iron, zinc, and phosphorus. Blueberries have significant antioxidant, anti-tumor, anti-viral and atherosclerosis prevention pharmacological activities. In addition, blueberries have many health benefits such as preventing brain nerve aging, protecting eyesight, strengthening the heart, anti-cancer, softening blood vessels, and enhancing human immune function. Blueberries are widely cultivated around the world, and the main economic production areas include the United States, the Netherlands, Canada and Germany. Blueberry fruits can be eaten directly or processed into jams, juices, dried fruits and other products.

A plurality of arc-shaped plastic vibration rods 53 are arranged on the upper vibration rod 47 and the lower vibration rod 52. According to the height of the blueberry bush, the upper vibration rod 47 and the lower vibration rod 52 can be folded and adjusted by the folding motor 1 46 and the folding motor 2 51 respectively, so that the arc-shaped plastic vibration rods 53 on the upper vibration rod 47 and the lower vibration rod 52 can act on the blueberry bush, and then the folding vibration rod 43 is driven to rotate and adjust by the rotary motor 2 50, and the upper vibration rod 47, the lower vibration rod 52 and the arc-shaped plastic vibration rod 53 are driven to vibrate up and down by the vibration motor 48 to shake the blueberries off.

[0032] Further improvement, such as Figure 1 As shown, the electric push rod 5 adopts an electric push rod with 100W and a thrust of 6000N.

[0033] Further improvement, such as Figure 1 As shown, the sliding shaft 6 and the sleeve 7 are of a specification of φ30m.

[0034] Further improvement, such as Figure 1 As shown, the electric push rod 10 uses an electric push rod with 750W and a thrust of 7000N.

[0038] Specifically, the arc-shaped plastic vibration rod 53 includes an arc-shaped plastic main rod 57 and a floating plastic rod 58 whose one end rotates with the arc-shaped plastic main rod 57. An elastic gasket 59 is formed between the arc-shaped plastic main rod 57 and the floating plastic rod 58. The elastic gasket 59 is made of elastic material and its surface is processed into a layered structure. When the arc-shaped plastic vibration rod 53 vibrates the blueberry branches up and down, the floating plastic rod 58 cooperates with the elastic gasket 59 to effectively improve the vibration effect and vibration frequency on the blueberry branches, thereby improving the effect of shaking off the blueberries on the blueberry branches.

[0039] When in use: When it is necessary to pick blueberries with the blueberry picking equipment, the walking chassis system is adjusted according to the space conditions of the blueberry planting area, and the two sets of square tubes 8 are pushed and rotated by the electric push rod 10. During the rotation of the square tube 8, the roller 9 moves down and contacts the ground, and the position of the crawler chassis 2 on the right side of the frame 1 is lifted. At this time, the crawler chassis 2 is pushed by the electric push rod 5 to move horizontally. Since the crawler chassis is heavy and has a large sliding resistance, it cannot be achieved by using a linear bearing module group. The rolling of the rollers on the sliding table is utilized. The friction resistance is small and the load-bearing capacity is large, so the spacing between the two sets of crawler chassis 2 is adjusted, so that the specifications of the walking chassis system can meet the space requirements of the driving area and the deep and narrow furrow operation characteristics of blueberry ridge cultivation. The transmission gear 19 is driven to rotate by the reduction motor 18, and the transmission gear 19 acts on the rack 20 during the rotation process, thereby driving the double-rail body 22 to adjust the longitudinal height, and then the disc 23 installed on the double-rail body 22, the slewing mechanism 13 and the horizontal movable cantilever 14 are adjusted in the longitudinal height, and then the slewing motor 3 is used to rotate the transmission gear 19. 3 drives the small gear 32 to rotate, and the small gear 32 acts on the large gear 31 during the rotation process. The large gear 31 drives the upper horizontal movable cantilever 14 to adjust the 270° rotation range during the rotation process, and performs real-time angle detection through the bull's eye 30 during the rotation process, so as to facilitate the horizontal movable cantilever 14 and the vibration picking system to rotate to the blueberry picking area. At this time, the screw rod is driven to rotate by the horizontal movable motor 39, and the screw rod acts on the nut assembly 38 and the cantilever beam 36 during the rotation process to move the horizontal position, thereby adjusting the vibration picking system. The position of the system is adjusted. According to the height of the blueberry bushes, the upper vibration rod 47 and the lower vibration rod 52 can be folded and adjusted respectively by the folding motor 1 46 and the folding motor 2 51, so that the arc-shaped plastic vibration rod 53 on the upper vibration rod 47 and the lower vibration rod 52 can act on the blueberry bushes, and then the folding vibration rod 43 is driven to rotate and adjust by the rotary motor 2 50, and the upper vibration rod 47, the lower vibration rod 52 and the arc-shaped plastic vibration rod 53 are driven to vibrate up and down by the vibration motor 48 to shake the blueberries off and complete the picking.
