Description

Technical Field

[0001] This utility model relates to the field of blueberry harvesting technology, and in particular to a harvesting device for blueberry cultivation. Background Technology

[0002] Blueberries, also known as Dusi, wild blueberries are called Dushi (in the Greater and Lesser Khingan Mountains and Yichun), Dianguo, Diguo, Longguo, and Hatangguo (in Jilin). Blueberries are rich in nutrients such as anthocyanins, which have functions such as protecting eyesight, anti-oxidation, anti-cancer, softening blood vessels, and enhancing the body's immunity. Furthermore, blueberries are increasingly popular due to their sweet taste and good texture, leading to a growing area of ​​blueberry cultivation.

[0003] Currently, ripe blueberries in my country are mainly harvested manually. However, blueberries are shrub berries with small fruit, making harvesting very difficult. This not only results in low work efficiency but also high labor intensity. This is especially true for lowbush blueberry varieties with a plant height between 5 and 40 centimeters, where harvesting is particularly arduous. Workers need to maintain a bent-over posture for extended periods and frequently reach their hands into the dense foliage to pick the fruit. Such actions can easily cause scratches on the hands, increasing discomfort and difficulty of the work.

[0004] The utility model patent with authorization announcement number CN216362645U discloses a manual blueberry picking device, including a picking can, an extension rod at one end of the picking can, a first handle on the extension rod, a detachable top cover at the upper end of the picking can, an operating lever at one end of the top cover, the middle section of the operating lever being hinged to the extension rod, a second handle at one end of the operating lever, a buffer plate inside the picking can, a feeding port at the center of the buffer plate, and a support frame inside the picking can, the support frame being positioned below the buffer plate. Compared with existing technologies, the advantages of this utility model are: it does not damage the blueberry branches, allows for continuous harvesting, and is more convenient; the extension rod and control lever extend the reach of the user's hand; the combination of the first and second grips, similar to scissors, allows the top cover to be opened relative to the harvesting can, and the blueberry branches to be inserted into the can. The branches are then secured by the clamps around the edge, preventing them from detaching. However, this utility model still has the following disadvantages: 1. It cannot separate blueberries from leaves, resulting in low-quality blueberries; 2. The harvesting process relies entirely on hand strength, which is not only inefficient but also labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a harvesting device for blueberry cultivation, which can separate leaves and fruit during the blueberry harvesting process, resulting in higher quality blueberry harvesting. Furthermore, the harvesting, separation, and collection processes are carried out continuously and automatically, requiring less manual labor and increasing work efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A blueberry harvesting device includes a branch clamping mechanism, which comprises a clamping part one and a clamping part two, respectively fixedly connected to a clamping arm one and a clamping arm two. The clamping part one is provided with a fruit and leaf separation harvesting mechanism, which is connected to a fruit storage box through a collection pipe. The fruit and leaf separation harvesting mechanism includes a rotating shaft rotatably connected to the clamping part one, with a plurality of comb plates arranged circumferentially on the rotating shaft. One end of the rotating shaft is connected to a harvesting drive motor fixed on the clamping part one.

[0008] By adopting the above technical solution, clamping part one and clamping part two, through the coordinated movement of clamping arm one and clamping arm two, can stably clamp and fix the blueberry branches. After the branches are firmly clamped, the fruit and leaf separation and harvesting mechanism located in clamping part one starts to operate. That is, the harvesting drive motor drives the rotating shaft to rotate, thereby driving each comb plate to rotate. During the rotation of the comb plate, the blueberries are continuously picked off the branches. Since the gap between the comb teeth on the comb plate can better adapt to the size and distribution characteristics of the blueberries, it can greatly reduce the possibility of leaves and other unwanted parts being collected together, thus achieving the effect of fruit and leaf separation. The separated blueberries enter the fruit storage box through the collection tube, realizing continuous operation. Throughout the process, the operator only needs to control the movement of clamping arm one and clamping arm two, which greatly reduces the labor intensity and significantly improves the harvesting efficiency and the collection quality of blueberries.

[0009] A further feature of this invention is that the clamping part one includes a side plate connected to the clamping arm one and a sieve plate fixed to the bottom of the side plate. The two ends of the side plate and the sieve plate are respectively connected by a limiting plate one and a limiting plate two. The two ends of the rotating shaft are respectively rotatably connected to the limiting plate one and the limiting plate two. The harvesting drive motor is fixed on the limiting plate one or the limiting plate two.

[0010] By adopting the above technical solution, the side plate, sieve plate, and limiting plate one and limiting plate two together form a bucket-shaped receiving cavity structure, which can better accommodate the picked blueberries and some leaves. The sieve plate can further separate the leaves and debris mixed in with the picked blueberries. The separated blueberries directly enter the collection tube below the sieve plate, while the separated leaves remain above the sieve plate. When clamping part one and clamping part two are opened, the leaves remaining above the sieve plate are automatically pushed out by the comb plate, ensuring that the blueberries that finally enter the storage box have better purity and effectively guarantee the quality of the collected blueberries.

[0011] A further feature of this invention is that the clamping part two includes a cover plate fixedly connected to the clamping arm two, the cover plate being opposite to the sieve plate, and a toothed plate being provided on the side of the cover plate away from the clamping arm two, the toothed plate being opposite to the side plate.

[0012] By adopting the above technical solution, the toothed plate works in conjunction with the sieve plate of the clamping part one. Driven by the clamping arm two, it clamps and fixes the branches, ensuring that the blueberries can be separated from the branches more effectively during the picking process. The toothed structure of the comb plate can fix the branches while reducing unnecessary damage to them. The clamping part two and the clamping part one cooperate to form a stable clamping space, which can effectively ensure the smooth separation of the blueberries from the branches. Through the dual filtration of the sieve plate and the toothed plate, the picked blueberries and some leaves can be further separated, thereby effectively improving the purity of the fruit.

[0013] A further feature of this invention is that the bottom of the sieve plate is provided with a collecting hopper, and the bottom of the collecting hopper is provided with a discharge port that communicates with the collecting pipe.

[0014] By adopting the above technical solution, the collection hopper is used to hold the blueberries separated by the sieve plate, ensuring that they enter the collection tube smoothly and preventing the fruits from rolling off, thus further optimizing the collection efficiency.

[0015] A further feature of this invention is that the other end of both the clamping arm one and the clamping arm two is provided with a handle, and the clamping arm one and the clamping arm two are arranged in an X-shape and connected in the middle by a connecting shaft.

[0016] By adopting the above technical solution, the handle design allows the operator to flexibly control the opening and closing of the X-shaped clamping arms one and two, thereby precisely controlling the opening and closing of clamping parts one and two, improving the convenience of harvesting, reducing manual operation fatigue, and increasing harvesting efficiency.

[0017] A further feature of this invention is that it includes a walking mechanism, which includes a support plate, a walking wheel at the bottom of the support plate, and a support seat on the support plate for supporting the branch clamping mechanism.

[0018] By adopting the above technical solution, the walking mechanism enables the entire device to move flexibly within the blueberry orchard, reducing the burden of manual handling and further improving the efficiency and convenience of harvesting operations.

[0019] A further feature of this invention is that the support base is provided with a horizontal adjustment shaft for connecting to the connecting shaft in the branch clamping mechanism. The horizontal adjustment shaft is perpendicular to the horizontal plane and rotatably connected to the support base. One end of the connecting shaft is rotatably connected to the horizontal adjustment shaft.

[0020] By adopting the above technical solution, the operator can swing the branch clamping mechanism according to the position and angle of the branch, so that the branch clamping mechanism can accurately clamp the branch to be picked, effectively improving the accuracy and efficiency of blueberry picking. In addition, by swinging the branch clamping mechanism, it can also adapt to a larger area of ​​picking in the same location, effectively improving the flexibility and coverage of picking, and further optimizing the picking efficiency.

[0021] A further feature of this invention is that a seat is also provided on the support plate.

[0022] By adopting the above technical solution, the seat design allows operators to sit comfortably during long harvesting periods, avoiding leg and back fatigue caused by prolonged standing and bending, and further reducing the difficulty of the work.

[0023] The beneficial effects of this utility model are:

[0024] 1. In this utility model, clamping part one and clamping part two, through the coordinated movement of clamping arm one and clamping arm two, can stably clamp and fix the blueberry branches. After the branches are firmly clamped, the fruit and leaf separation and harvesting mechanism located in clamping part one starts to operate. That is, the harvesting drive motor drives the rotating shaft to rotate, thereby driving each comb plate to rotate. During the rotation of the comb plate, the blueberries are continuously picked off the branches. Since the gap between the comb teeth on the comb plate can better adapt to the size and distribution characteristics of the blueberries, it can greatly reduce the possibility of leaves and other unwanted parts being collected together, thus achieving the effect of fruit and leaf separation. The separated blueberries enter the fruit storage box through the collection tube, realizing continuous operation. Throughout the process, the operator only needs to control the movement of clamping arm one and clamping arm two, which greatly reduces the labor intensity and significantly improves the harvesting efficiency and the collection quality of blueberries.

[0025] 2. In this utility model, the clamping part one, together with the side plate, the sieve plate, the limiting plate one, and the limiting plate two, forms a bucket-shaped receiving cavity structure, which can better accommodate the picked blueberries and some leaves. The sieve plate can further separate the leaves and debris mixed in with the picked blueberries. The separated blueberries directly enter the collection tube below the sieve plate, while the separated leaves remain above the sieve plate. When the clamping part one and the clamping part two are opened, the leaves remaining above the sieve plate are automatically pushed out by the comb plate, ensuring that the blueberries that finally enter the storage box have better purity and effectively guaranteeing the quality of the collected blueberries.

[0026] 3. In this utility model, the second clamping part works in conjunction with the sieve plate of the first clamping part through the comb plate. Driven by the second clamping arm, it clamps and fixes the branches, ensuring that the blueberries can be separated from the branches more effectively during the picking process. The toothed structure of the comb plate can fix the branches while reducing unnecessary damage to them. The second clamping part and the first clamping part cooperate to form a stable clamping space, which can effectively ensure the smooth separation of the blueberries from the branches. Through the dual filtration of the sieve plate and the toothed plate, the picked blueberries and some leaves can be further separated, thereby effectively improving the purity of the fruit.

[0027] 4. The horizontal adjustment shaft in this utility model allows the operator to swing the branch clamping mechanism according to the position and angle of the branch, so that the branch clamping mechanism can accurately clamp the branch to be picked, effectively improving the accuracy and efficiency of blueberry picking. Furthermore, by swinging the branch clamping mechanism, it can also adapt to a larger area of ​​picking in the same location, effectively improving the flexibility and coverage of picking, and further optimizing picking efficiency.

[0028] 5.

[0034] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] like Figures 1-3 As shown, a blueberry harvesting device includes a branch clamping mechanism 1, which includes a clamping part 11 and a clamping part 12. The clamping part 11 and the clamping part 12 are fixedly connected to a clamping arm 13 and a clamping arm 14, respectively. A fruit and leaf separation harvesting mechanism 2 is provided inside the clamping part 11. The fruit and leaf separation harvesting mechanism 2 is connected to a fruit storage box 4 through a collection pipe 3. The fruit and leaf separation harvesting mechanism 2 includes a rotating shaft 21 that is rotatably connected to the clamping part 11. A plurality of comb plates 22 are arranged circumferentially on the rotating shaft 21. One end of the rotating shaft 21 is connected to a harvesting drive motor 23 fixed on the clamping part 11.

[0036] Furthermore, the clamping part 11 includes a side plate 111 connected to the clamping arm 13 and a sieve plate 112 fixed to the bottom of the side plate 111. The two ends of the side plate 111 and the sieve plate 112 are respectively connected by a limiting plate 113 and a limiting plate 214. The two ends of the rotating shaft 21 are respectively rotatably connected to the limiting plate 113 and the limiting plate 214. The harvesting drive motor 23 is fixed on the limiting plate 113 or the limiting plate 214.

[0037] Furthermore, the clamping part 2 12 includes a cover plate 121 fixedly connected to the clamping arm 2 14. The cover plate 121 is opposite to the sieve plate 112. A toothed plate 122 is provided on the side of the cover plate 121 away from the clamping arm 2 14. The toothed plate 122 is opposite to the side plate 111.

[0038] Furthermore, the bottom of the sieve plate 112 is provided with a collection hopper 5, and the bottom of the collection hopper 5 is provided with a discharge port 6 that communicates with the collection pipe 3.

[0039] Furthermore, each of the clamping arms 13 and 14 is provided with a handle 7 at the other end. The clamping arms 13 and 14 are arranged in an X-shaped cross configuration and are connected by a connecting shaft 1 at their midpoints.

[0040] Furthermore, it also includes a walking mechanism 8, which includes a support plate 81, a walking wheel 82 at the bottom of the support plate 81, and a support seat 83 on the support plate 81 for supporting the branch clamping mechanism 1.

[0041] Furthermore, the support base 83 is provided with a horizontal adjustment shaft 84 for connecting to the connecting shaft 15 in the branch clamping mechanism 1. The horizontal adjustment shaft 84 is perpendicular to the horizontal plane and rotatably connected to the support base 83. One end of the connecting shaft 15 is rotatably connected to the horizontal adjustment shaft 84.

[0042] Furthermore, a seat 9 is also provided on the support plate 81.

[0043] The working principle of this utility model is as follows: The operator operates the clamping arm 13 and clamping arm 14 via the handle 7, causing the clamping parts 11 and 12 in the branch clamping mechanism 1 to clamp the blueberry branch to be harvested. Then, the fruit and leaf separation harvesting mechanism 2 is started, and the harvesting drive motor 23 drives the rotating shaft 21 to rotate, thereby causing each comb plate 22 to rotate accordingly. During the rotation of the comb plates 22, the blueberries are continuously picked off the branches. Because the gap between the comb teeth on the comb plates 22 can adapt well to the size and distribution characteristics of the blueberries, it can pick a large number of blueberries. This significantly reduces the possibility of leaves and other unwanted parts being collected together, thus achieving fruit-leaf separation. The clamping part 11, together with the side plate 111, sieve plate 112, limiting plate 113, and limiting plate 114, forms a bucket-shaped receiving cavity structure, which can effectively accommodate the picked blueberries and some leaves. The sieve plate 112 can further separate the leaves and debris mixed in with the picked blueberries. The separated blueberries directly enter the collection tube 3 below the sieve plate 112, while the separated leaves remain on the sieve plate 112. Above 12, when clamping part one 11 and clamping part two 12 are opened, the leaves remaining above the sieve plate 112 are automatically pushed out by the comb plate 22, ensuring better purity of the blueberries that finally enter the storage box 4, effectively guaranteeing the quality of the collected blueberries; clamping part two 12 works in coordination with the sieve plate 112 of clamping part one 11 through the comb plate 22, and under the drive of clamping arm two 14, it clamps and fixes the branches, ensuring that the blueberries can be separated from the branches more effectively during the harvesting process. Among them, the toothed structure of the comb plate 22 can reduce the weight of the branches while fixing them. To minimize unnecessary damage to the branches, the clamping part 2 12 and clamping part 1 11 work together to form a stable clamping space, effectively ensuring the smooth separation of blueberry fruits from branches. Through the dual filtration of the sieve plate 112 and the toothed plate, the picked blueberry fruits and some leaves can be further separated, thereby effectively improving the purity of the fruit. The entire process is continuously automated, and the operator only needs to control the movement of clamping arm 1 13 and clamping arm 2 14, which greatly reduces labor intensity and significantly improves picking efficiency and the quality of blueberry collection.
