Description

Technical Field

[0001] This utility model relates to the field of greenhouse blueberry harvesting technology, specifically a suspended greenhouse blueberry harvesting device. Background Technology

[0002] Blueberries have a delicate and juicy flesh, a sweet and sour taste, and are rich in nutrients such as anthocyanins and vitamin C. With the development of technology, greenhouse blueberries have gradually become more common, and most blueberries are now harvested using pickers.

[0003] For example, a suspended greenhouse blueberry picking device with announcement number CN221784704U has a walking mechanism installed above the main body of the picking device, which enables the main body of the picking device to move freely on a plane and move between rows. This device solves the problem of low picking efficiency and the need for a large amount of labor when picking blueberries manually.

[0004] While existing greenhouse blueberry picking devices have solved the problem of low efficiency in manual blueberry picking, the sloping boards used for catching the blueberries make them susceptible to damage when they fall, affecting their appearance. Furthermore, the devices do not process the leaves and branches picked along with the berries, requiring manual sorting after harvesting, which increases labor costs and reduces picking efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a suspended greenhouse blueberry picking device to solve the problem mentioned in the background art that existing greenhouse blueberry picking devices do not screen branches and leaves during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended greenhouse blueberry picking device, comprising an adjustable support assembly, on which a drop-buffered picking assembly is slidably mounted, and a swaying screening assembly is provided below the side end of the drop-buffered picking assembly; the swaying screening assembly includes a protective box and a screening mesh frame disposed within the protective box, through which blueberries are screened; the drop-buffered picking assembly includes a limiting frame, a fixed frame, a rotating column, and a blocking column, the limiting frame being disposed on the top side of the swaying screening assembly, a rotating column being rotatably mounted within the limiting frame, a blocking column being fixedly mounted on the outer surface of the rotating column, a fixed frame being provided at the bottom of the rotating column, and a buffer cloth being installed inside the fixed frame.

[0007] Furthermore, the adjustable support assembly includes two horizontally arranged support frames and vertically arranged support legs at the four corners of the support frames. A suspension frame is slidably installed below the support frames, and the drop-buffered picking assembly is installed on the suspension frame.

[0008] Furthermore, the two horizontally arranged support frames are each rotatably mounted with a first threaded rotating rod. The same end of the two first threaded rotating rods is connected to a chain via a sprocket. A first servo motor is fixedly mounted on the support frame, and the output shaft of the first servo motor is connected to one of the sprockets via a spline.

[0009] Furthermore, the suspension bracket is fitted onto the two first threaded rods through threaded holes on the upper protrusion, thereby slidably mounted below the support frame.

[0010] Furthermore, a second threaded rod is rotatably mounted inside the suspension frame, and two collars are fixedly mounted above the limiting frame, each collar being sleeved on the second threaded rod.

[0011] Furthermore, a connecting shaft is fixedly installed above the rotating column, and the connecting shaft is rotatably installed on the top of the limiting frame.

[0012] Furthermore, the top of the protective box is fixedly connected to the limiting frame by bolts.

[0013] Furthermore, a limiting groove is provided inside the protective box, a screening frame is slidably installed inside the limiting groove, and a collection box is slidably installed below the screening frame.

[0014] Furthermore, a connecting plate is fixedly installed on the side end of the screening frame, and a support rod is rotatably installed on the side end of the connecting plate; a second servo motor is fixedly installed on the side end of the protective box, and a rotating disk is splined on the output shaft of the second servo motor. The rotating disk is rotatably connected to the support rod through an eccentric shaft. The distance that the rotating disk, together with the support rod and the connecting plate, pulls the screening frame to move is equal to the length of the screening frame's border.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This suspended greenhouse blueberry picking device works by driving the screening frame to repeatedly move within the limiting groove when blueberries and leaves fall above it. This creates a shaking motion that causes the blueberries to fall from the gaps and be collected. The device can sort the picked blueberries during use, thus avoiding subsequent manual sorting and improving the efficiency of the device. Furthermore, the power source drives the connecting shaft and rotating column to rotate, and together with the blocking column, it clamps and moves the blueberries on the branches, causing the blueberries to fall off. The fallen blueberries fall into the cushioning cloth, which cushions them and reduces the damage caused by the impact, thereby protecting the appearance of the blueberries and improving the harvesting quality of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1 and Figures 3-6A suspended greenhouse blueberry picking device is disclosed to address the problem that existing suspended greenhouse blueberry picking devices generally cannot screen branches and leaves during use. The device includes an adjustable support assembly 1, a drop-buffered picking assembly 2 slidably mounted on the adjustable support assembly 1, and a swaying screening assembly 3 located below the side of the drop-buffered picking assembly 2. The swaying screening assembly 3 includes a protective box 31 and a screening mesh frame 35 disposed within the protective box 31, through which blueberries are screened. The drop-buffered picking assembly 2 includes a limiting frame 21, a fixed frame 23, a rotating column 25, and a blocking column 27. The limiting frame 21 is located on one side of the top of the swaying screening assembly 3, the rotating column 25 is rotatably mounted within the limiting frame 21, and a blocking column 27 is fixedly mounted on the outer surface of the rotating column 25. A fixed frame 23 is set at the bottom of the column 27 and the rotating column 25. A buffer cloth 24 is installed inside the fixed frame 23. The upper part of the protective box 31 is fixedly connected to the limiting frame 21 by bolts 32. A limiting groove 33 is opened inside the protective box 31. A screening frame 35 is slidably installed inside the limiting groove 33. A collection box 34 is slidably installed below the screening frame 35. A connecting plate 36 is fixedly installed on the side end of the screening frame 35. A support rod 37 is rotatably installed on the side end of the connecting plate 36. A second servo motor 38 is fixedly installed on the side end of the protective box 31. A rotating disk 39 is splined on the output shaft of the second servo motor 38. The rotating disk 39 is rotatably connected to the support rod 37 through an eccentric shaft. The distance that the rotating disk 39 moves when it pulls the screening frame 35 with the support rod 37 and the connecting plate 36 is equal to the length of the frame of the screening frame 35.

[0020] according to Figure 3 , Figure 5 and Figure 6 The harvesting operation for ripe blueberries is carried out by a falling buffer-type harvesting component 2 in conjunction with an adjustable support component 1. When the blueberries and branches enter the protective box 31, the user starts the second servo motor 38. The output shaft at the side of the second servo motor 38 drives the rotating disk 39 to rotate, which in turn pulls the support rod 37 to slide and rotate. Since the other side of the support rod 37 is connected to the connecting plate 36, when the support rod 37 rotates, it can work with the connecting plate 36 to pull the screening frame 35 to sway within the limiting groove 33, and the pulling distance is equal to that of the screening frame 35. With a frame length of 5, there will be no gap between the screening frame 35 and the inner wall of the protective box 31 when it is pulled, preventing leaves from falling into the collection box 34 below. When blueberries fall from the protective box 31 to the top of the screening frame 35, they will pass through the gap in the screening frame 35 and fall into the collection box 34 for collection. The branches and leaves, due to their larger size, will remain on the top of the screening frame 35. At this time, the user can remove the branches and leaves on the top of the screening frame 35 through the side opening of the protective box 31, thereby separating the blueberries from the branches and leaves.

[0021] Example 2: Figures 1-4 The technical solution shown, based on Embodiment 1, further discloses, in order to solve the problem that existing suspended greenhouse blueberry picking devices are easily damaged when blueberries fall into the device: The adjustable support assembly 1 includes two horizontally arranged support frames 11 and vertically arranged support legs 16 at the four corners of the support frames 11. A suspension frame 17 is slidably installed below the support frames 11, and the fall-buffered picking assembly 2 is installed on the suspension frame 17. First threaded rotating rods 12 are rotatably installed inside the two horizontally arranged support frames 11, and the same end of the two first threaded rotating rods 12 is connected to a chain 1 via a sprocket 13. 4. A first servo motor 15 is fixedly installed on the support frame 11. The output shaft of the first servo motor 15 is connected to one of the sprockets 13 via a spline. The suspension frame 17 is sleeved on two first threaded rotating rods 12 through the threaded holes on the upper protrusion, thereby slidingly installed below the support frame 11. A second threaded rotating rod 18 is rotatably installed inside the suspension frame 17. Two collars 22 are fixedly installed on the upper part of the limiting frame 21. Each collar 22 is sleeved on the second threaded rotating rod 18. A connecting shaft 26 is fixedly installed on the upper part of the rotating column 25. The connecting shaft 26 is rotatably installed on the top of the limiting frame 21.

[0022] according to Figures 1 to 4 When ripe blueberries need to be picked, the user starts the first servo motor 15. Its side output shaft drives the connected sprocket 13 to rotate, which in turn drives another sprocket 13 to rotate synchronously via the chain 14. The two sprockets 13 rotate together, causing the two first threaded rods 12 to rotate. This, in turn, cooperates with the protrusion on the top of the suspension frame 17 to push the suspension frame 17 to slide back and forth. Then, a power source is connected to the side of the second threaded rod 18, which drives the second threaded rod 18 to rotate. This, in conjunction with the collar 22, pushes the falling buffer picking component 2 to slide left and right, thereby changing the picking position of the device. The user connects a power source above the connecting shaft 26, which drives the connecting shaft 26 to rotate, thereby driving the rotating column 25 to rotate. When the rotating column 25 rotates, it can work with the blocking column 27 to clamp and push the blueberries on the branch. Under the rotation of the rotating column 25, the blueberries are detached from the branch. After detachment, the blueberries will fall onto the cushioning cloth 24. Since the cushioning cloth 24 is made of soft material, it will cushion the blueberries when they fall, reducing the chance of the blueberries being broken during picking. The low-lying part of the cushioning cloth 24 is connected to the inside of the protective box 31, so the fallen blueberries will enter the protective box 31 for subsequent screening operations.
