Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a height-adjustable fruit picking device. Background Technology

[0002] In the process of fruit cultivation, as the fruit trees age, their height also increases, and their branches become more lush. This increases the amount of fruit on the trees, resulting in higher yields for fruit farmers, which is a desirable outcome. However, as the fruit trees grow taller, the difficulty of harvesting also increases. For harvesting fruit from higher locations, lifting platforms are now commonly used to elevate workers to a suitable height for easier harvesting.

[0003] However, in actual use, while lifting platforms make it easier for workers to pick fruit, it is difficult to transfer the fruit to the ground. Current solutions either involve lowering the height of the lifting platform after it is full of fruit and then transferring it, or having two or more workers pass the fruit down during the picking process. The former is cumbersome and inefficient, while the latter requires more manpower and the safety of passing the fruit up and down is difficult to guarantee. Therefore, a height-adjustable fruit picking device is specially provided. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a height-adjustable fruit picking device, which solves the problem of inconvenient fruit transfer when using existing fruit picking lifting platforms.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a height-adjustable fruit picking device, including a lifting and carrying unit, wherein a circulating feeding unit is installed on one side of the lifting and carrying unit, and the circulating feeding unit includes;

[0019] A sliding component is slidably disposed in the support rail and is fixedly connected to the fixed part;

[0020] The lifting cylinder has its top end fixedly connected to the support rail and its bottom end fixedly connected to the sliding component.

[0021] Preferably, a support rod is fixedly installed between the bottom end of the support rail and the manned platform, a bracket is fixedly installed on the side of the manned platform, and the bottom end of the fixed frame is slidably installed on the top of the bracket.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This application provides a height-adjustable fruit picking device, which solves the problem of inconvenient fruit transfer in existing fruit picking lifting platforms.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] This utility model discloses a height-adjustable fruit picking device for fruit trees.

[0035] Example 1

[0036] According to the appendix Figure 1-4As shown, the system includes a lifting and carrying unit 1, and a circulating unloading unit 2 is installed on one side of the lifting and carrying unit 1. The circulating unloading unit 2 includes two sets of fixed frames 21, two sets of circulating traction chains 23, a connecting shaft 25, and a hanging basket 26. The two sets of fixed frames 21 are arranged side by side on one side of the lifting and carrying unit 1; the two sets of circulating traction chains 23 are respectively arranged inside the two sets of fixed frames 21; the two ends of the connecting shaft 25 are respectively fixedly connected to the two sets of circulating traction chains 23; the hanging basket 26 is suspended on the connecting shaft 25.

[0037] The lifting manned unit 1 includes a base 11, a scissor lift 12, a manned platform 13, and a protective frame 14. The manned platform 13 is located above the base 11. The scissor lift 12 is installed between the base 11 and the manned platform 13 and is used to adjust the height of the manned platform 13. The protective frame 14 is fixedly welded to the top of the manned platform 13.

[0038] A connecting frame 22 is fixedly welded between the tops of the two sets of fixed frames 21. A servo motor 24 is fixedly installed on the outside of the fixed frame 21. A sprocket is installed at the output end of the servo motor 24, and the sprocket meshes with the circulating traction chain 23.

[0039] Working principle: In use, the device is mounted on a carrier 11, which transports the entire device to the orchard. During harvesting, workers first climb onto the platform 13, then activate the shear lift 12 to raise the platform 13, allowing workers to reach the fruit higher up the trees. Then, the servo motor 24 is activated, driving the circulating traction chain 23 to circulate within the fixed frame 21. Simultaneously, the circulating traction chain 23 drives multiple connecting shafts 25 to circulate between the two sets of fixed frames 21. The hanging basket 26 is suspended on the connecting shaft 25, and the hanging basket 26 is moved to the top of the fixed frame 21 by the circulating traction chain 23. At this time, the servo motor 24 stops. The picking workers place the picked fruit directly into the hanging basket 26. Under the action of gravity, the hanging basket 26 always remains vertically suspended. When the top hanging basket 26 is full, the servo motor 24 is started to drive the hanging basket 26 to move downward. At this time, the personnel below remove the full hanging basket 26 and then hang a new empty hanging basket 26, thus realizing the cyclical transfer of picked fruit, which is efficient, convenient to operate, and safer.

[0040] Example 2

[0041] According to the appendix Figure 1-4 As shown, based on Embodiment 1, more specifically, the circulating feeding unit 2 also includes a lifting support 27, which is installed on the manned platform 13 and the protective frame 14 and is used to adjust the height of the two sets of fixed frames 21.

[0042] The lifting support component 27 includes a fixed part 271, a support rail 272, a sliding part 273, a lifting cylinder 274, a support rod 275, and a bracket 276. The fixed part 271 is fixedly installed on the outside of the fixed frame 21. The top end of the support rail 272 is fixedly installed on the protective frame 14. The sliding part 273 is slidably installed in the support rail 272 and is fixedly connected to the fixed part 271. The top end of the lifting cylinder 274 is fixedly connected to the support rail 272, and its bottom end is fixedly connected to the sliding part 273. The support rod 275 is fixedly installed between the bottom end of the support rail 272 and the manned platform 13. The bracket 276 is fixedly installed on the side of the manned platform 13. The bottom end of the fixed frame 21 is slidably installed on the top of the bracket 276.

[0043] Working principle: When harvesting, the device activates the lifting cylinder 274, causing its output end to extend outward. This, in turn, drives the fixing frame 21 to slide downward along the support rail 272 via the fixing part 271. At this time, the bottom of the fixing frame 21 is always in contact with the top of the bracket 276, which provides support. Ultimately, the bottom of the fixing frame 21 is close to the ground, making it convenient for the fruit to be unloaded. After use, the output shaft of the lifting cylinder 274 is retracted, causing the fixing frame 21 to rise, thus preventing the lower end of the fixing frame 21 from contacting and colliding with the ground during transport, which could lead to damage.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
