Description

Technical Field

[0001] This utility model relates to the field of agricultural and forestry machinery technology, and in particular to a device for collecting and sorting spherical fruits. Background Technology

[0002] Currently, the collection and sorting of fruits in China mostly involves harvesting from orchards and then transporting them to a sorting center. At the sorting center, the fruits are sorted and arranged manually, or placed in a grading machine for size classification. The grading process requires the use of conveyor belts, rollers, and other devices, resulting in complex machine structures, large sizes, and high prices.

[0003] For example, the utility model patent CN204948791U, which describes an automatic spherical fruit harvesting device, can classify fruits based on size, but the device is quite large during operation and occupies a significant amount of space when not in use, making it impossible to save space by folding. The utility model patent application CN 118489420A discloses a jackfruit harvesting device with a buffer-type collection basket, but it can only collect larger fruits and cannot collect a large number of smaller fruits.

[0004] The current design of spherical fruit collection and sorting devices still has the following problems:

[0005] 1. The collection and sorting process has a single function: Currently, the collection and sorting of spherical fruits is divided into two steps, and the working methods used in each step are quite different, resulting in a single function.

[0006] 2. Low sorting efficiency: Currently, the fruit sorting process requires transporting the collected fruits to a grading machine, which then sorts the fruits according to their size. This process takes a long time and results in low sorting efficiency.

[0007] 3. The equipment is too large: Fruit sorting is mostly done by grading machines, which contain multiple equipment modules, such as conveyor belts and rollers, and the equipment occupies too much space.

[0008] In view of the above reasons, this utility model proposes a device for collecting and sorting spherical fruits to solve the above technical problems. Utility Model Content

[0039] like Figure 1-7 As shown, a device for collecting and sorting spherical fruits is provided, comprising a collection module and a sorting module. The collection module includes a collection basket 1 and a collection basket bottom plate 2 located below it. The bottom of the collection basket 1 has an opening, and the harvested fruits are placed inside the collection basket 1 for collection. The side of the collection basket bottom plate 2 is rotatably connected to the side of the collection basket 1 via a rotating component. One end of the collection basket bottom plate 2 is open, and its surface is provided with multiple slides for the spherical fruits to slide down. By using the rotating component, after the collection basket 1 is full of fruits, i.e., after the collection state is over, its front end can be rotated and lifted relative to the collection basket bottom plate 2, so that the fruits fall from the bottom opening and slide down the slides on the collection basket bottom plate 2. Then, the sorting module performs preliminary sorting of the fruits according to their size.

[0040] The sorting module is located below the bottom plate 2 of the collection basket and includes a first sorting plate 3 and a second sorting plate 4 located below it. The first sorting plate 3 is rotatably connected to both the bottom plate 2 and the second sorting plate 4 via a transmission rod assembly. The rotation of the transmission rod assembly allows the first sorting plate 3 and the second sorting plate 4 to rotate and unfold at a certain angle relative to the bottom plate 2 of the collection basket. Both the first sorting plate 3 and the second sorting plate 4 are provided with slides, and multiple first screening holes 5 and second screening holes 6 are respectively opened on the slides. The first screening holes 5 are used to sort out small fruits that are small enough to fall through the slides. The second screening holes 6 are used to sort out medium fruits that are medium enough to fall through the first screening holes 5 and large fruits that are large enough to fall through the second screening holes 6. Large fruits can slide down the slides from the end of the second sorting plate 4. Fruit baskets or bags or other containers can be placed below the areas where the first screening holes 5 and the second screening holes 6 are located and at the end of the second sorting plate 4 to separate the fruits of different sizes after the initial sorting.

[0041] In this embodiment, the rotating assembly includes a first crank 7, a second crank 8, and a guide rail slide mechanism. Both the first crank 7 and the second crank 8 are rotating pairs formed by the rotatable connection of two rods. Both ends are rotatably connected to the rear side of the bottom plate 2 of the collection basket and the side of the collection basket body 1, respectively. Through the telescopic support of the guide rail slide mechanism and the rotational action of the first crank 7 and the second crank 8, the front end of the collection basket body 1 can be lowered and raised relative to the bottom plate 2, used for collecting and sorting fruits, respectively. During fruit collection, the bottom plate 2 and the collection basket body 1 are in a closed state, with the first sorting plate 3 and the second sorting plate 4 folded and placed below the bottom plate 2. After collection, the collection basket body 1 is raised, and the fruits inside fall into the bottom plate 2 and slide down the slide to be sorted by the sorting module.

[0042] Specifically, the guide rail slide mechanism includes a guide rail 9 and a slide rod 10 that slides with it. The end of the guide rail 9 is movably connected to the middle of the top side of the collection basket 1. The slide rod 10 can extend and retract relative to the guide rail 9, and the extension and retraction process is damped to ensure that it remains in a certain position after extension. The end of the slide rod 10 is connected to the rotating joint of the second crank 8. A connecting rod of the second crank 8 extends downward and is rotatably connected to the side of the bottom plate 2 of the collection basket with one end of the first crank 7. Through the above structure, the first crank 7 and the second crank 8 can move in coordination during the extension and retraction of the guide rail slide mechanism.

[0043] In this embodiment, the top of the collection basket 1 is provided with a plurality of symmetrically arranged hanging ears 11, which can be used to tie ropes to achieve the purpose of suspension, and then used in conjunction with equipment such as robotic arms or picking platforms.

[0044] Specifically, the transmission rod assembly includes a third crank 12 and a first connecting rod 13 for rotatably connecting the rear side of the first sorting plate 3 to the front side of the collection basket bottom plate 2, and a fourth crank 14 and a second connecting rod 15 for rotatably connecting the rear side of the second sorting plate 4 to the front side of the first sorting plate 4. The ends of each crank and connecting rod are rotatably connected to the collection basket body 1, the collection basket bottom plate 2, the first sorting plate 3, and the second sorting plate 4 via pins. The collection basket bottom plate 2, the first sorting plate 3, and the second sorting plate 4 are all scoop-shaped structures with baffles at the rear and open fronts. When the second sorting plate 4, the first sorting plate 3, and the collection basket bottom plate 2 are rotated open relative to each other, their surface grooves connect horizontally. During the sorting process, the collection basket bottom plate 2, the first sorting plate 3, and the second sorting plate 4 are arranged in a stepped manner, and the collection basket bottom plate 2, the first sorting plate 3, and the second sorting plate 4 are all tilted at a certain angle to facilitate the rolling of spherical fruits. In addition, the nearest second screening hole 6 on the first sorting plate 3 and the second sorting plate 4 is a certain distance apart to prevent small fruits sorted from the first sorting plate 3 from accidentally falling into the second sorting plate 4, resulting in incomplete sorting.

[0045] In this embodiment, the first sieve holes 5 are evenly distributed on the side of the first sorting plate 3 near its rear end, and the second sieve holes 6 are evenly distributed on the surface of the second sorting plate 4. The width of the slide on the first sorting plate 3 is smaller than the width of the slide on the second sorting plate 4, which allows the fruit to slide down along a specific slide. The diameter of the first sieve hole 5 is smaller than the diameter of the second sieve hole 6. The first sieve hole 5 is used to sort out small fruits with a diameter smaller than its own, and the second sieve hole 6 is used to sort out medium fruits with a diameter smaller than its own and large fruits with a diameter larger than its own.

[0046] The bottom of the collection basket base plate 2 is provided with a retractable first limiting post 16, which is used to limit the position of the third crank 12 in the non-sorting state. The side of the collection basket body 1 is provided with a retractable second limiting post 17, which is used to limit the position of the first crank 7 in the collecting state. Through the above structure, the positions of the first crank 7 and the third crank 12 can be limited when the device is folded and stored or when collecting fruits, thereby ensuring the overall stability of the device.

[0047] In this embodiment, a chute 18 with a certain angle is provided inside the collection basket 1 to reduce damage to the fruit caused by being placed from a height. At the same time, the chute 18 can limit the space at the outlet, making it easier to control the speed and quantity of the fruit entering the first sorting plate 3.

[0048] In this embodiment, the side of the second sorting plate 4 is designed with a fixing ear plate 19, which can be used to connect external structures such as platforms or brackets to balance the overall center of gravity of the equipment.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
