Description

Technical Field

[0001] This utility model relates to the field of lifting platforms, specifically a lifting platform for agricultural machinery. Background Technology

[0002] In a modern orchard management system, pruning, bagging, and harvesting of fruit trees are crucial steps in ensuring fruit quality and yield. Pruning optimizes light and ventilation conditions for fruit trees, promoting healthy growth. Bagging effectively isolates pests and diseases, reduces pesticide residues, and improves the appearance of the fruit. Harvesting is the key step in harvesting fruit, affecting its freshness and integrity. However, these operations usually require operators to frequently move among the branches and leaves of fruit trees at different heights.

[0003] In traditional orchards, workers typically use A-frame ladders for climbing during fruit harvesting. While A-frame ladders are simple in structure and inexpensive, they have many drawbacks in actual operation. With the development of modern agriculture towards large-scale and intensive operations, mobile lifting platforms are increasingly being used in orchards to improve operational efficiency and ensure worker safety. These platforms utilize a tracked drive system for flexible movement, and their high-strength tracks provide strong grip and adaptability, enabling stable operation on muddy and uneven terrain. The platform uses hydraulic cylinders as its core actuators, precisely controlling oil pressure and flow through the hydraulic system to achieve smooth and rapid lifting, providing workers with a stable and spacious operating platform.

[0004] Currently, when harvesting fruit from fruit trees, pickers typically carry nylon bags for storage, collecting the harvested fruit into the bags for transportation. However, during the harvesting process, pickers need to use one hand to pick the fruit and the other hand to adjust the opening of the nylon bag, resulting in low harvesting efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lifting platform for agricultural machinery to solve the technical problem of low harvesting efficiency when harvesters stand on a movable lifting platform to pick fruits.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform for agricultural machinery, including a fruit harvester, a storage box fixed to the top of the fruit harvester, a storage compartment inside the storage box, a door panel installed on one side of the storage box, a lifting assembly installed on the top of the storage box, a lifting platform connected to the top of the lifting assembly, a rotating column movably installed on the top of the lifting platform, a conveying assembly inside the rotating column, the conveying assembly including a flexible hose connected to the inside of the storage compartment, a conveying pipe connected to the top of the flexible hose, and a feeding hopper installed at the end of the conveying pipe.

[0007] By adopting the above technical solution, the problem of low picking efficiency when picking fruits while standing on a movable lifting platform is solved. After the lifting component raises the lifting platform to a suitable height, the picker can push the connecting rod to rotate and move the feeding bucket near the fruit, making it convenient for the picker to put the fruit into the feeding bucket. After the fruit is placed in the feeding bucket, it slides down the inner wall of the feeding bucket into the conveying pipe. The fruit in the conveying pipe falls into the collection bin through the hose, thus enabling the picker to pick fruits with both hands and increasing the fruit picking rate.

[0008] The present invention is further configured such that the inner wall of the feeding hopper is funnel-shaped, and the inner wall diameter at the top of the feeding hopper is larger than the inner wall diameter at the bottom.

[0009] Preferably, the inner wall of the feeding hopper is funnel-shaped, which makes it convenient for harvesters to place the fruit into the feeding hopper.

[0010] The present invention is further configured such that a fixing sleeve is fitted on the outer wall of the conveying pipe, a connecting rod is connected to one side of the fixing sleeve, a fixing plate is fixed to the end of the connecting rod, and multiple sets of connecting columns are connected to the bottom of the fixing plate.

[0011] Preferably, the fixing sleeve secures the feeding hopper and the conveying pipe, so that the feeding hopper can withstand the weight of the fruit when the harvester places the fruit in it.

[0012] The present invention is further configured such that the lifting assembly includes a hydraulic cylinder, the end of the hydraulic cylinder is connected to a lifting rod, and lifting frames are installed on both sides of the lifting rod.

[0013] Preferably, the harvester can control the hydraulic cylinder to push the lifting rod, and the movement of the lifting rod drives the lifting frame to raise the lifting platform.

[0014] The present invention is further configured such that the bottom end of the rotating column is located inside the lifting platform, and a bearing is sleeved on the outer wall of the bottom end of the rotating column.

[0015] Preferably, during the fruit picking process, the picker can push the connecting rod to make the rotating column rotate, causing the dispensing bucket to rotate and move closer to the fruit. The bearings fitted on the outer wall of the rotating column can reduce the rotational resistance of the rotating column, thus facilitating the picker to rotate the dispensing bucket.

[0016] The present invention is further configured such that a guardrail is installed on the top of the lifting platform, and the height of the guardrail is lower than the height of the fixed plate.

[0017] Preferably, the guardrail protects the pickers standing on top of the lifting platform, preventing them from falling while picking fruit.

[0018] The present invention is further configured such that the hose is made of rubber, and the inner diameter of the hose is larger than the maximum diameter of the fruit.

[0019] Preferably, during the lifting process, the rubber hose can extend and lengthen, allowing the hose to provide a passage between the connecting pipe and the storage box.

[0020] The present invention is further provided that the inner wall of the storage box is equipped with a mesh bag, and the top of the mesh bag is fixed with an installation ring.

[0021] Preferably, the net is fixedly installed in the storage box at one end of the hose by an installation ring.

[0022] The present invention is further configured such that the inner wall of the net bag is conical, the net bag is made of a mesh with a pore size of 1cm, and a shaping ring is installed at the bottom of the net bag.

[0023] Preferably, the shaping ring ensures that the bottom of the net bag remains round, thus preventing excessive accumulation of fruit in the net bag and causing blockage.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model solves the problem of low harvesting efficiency when harvesters stand on a movable lifting platform to pick fruits by setting up a fruit harvester, a storage box, a conveying component, a lifting component, a rotating column, and a connecting rod. After the lifting component raises the lifting platform to a suitable height, the harvester can push the connecting rod to rotate and move the feeding bucket near the fruit, making it convenient for the harvester to put the fruit into the feeding bucket. After the fruit is placed in the feeding bucket, it slides down the inner wall of the feeding bucket into the conveying pipe. The fruit in the conveying pipe falls into the storage bin through the hose, thus enabling the harvester to pick fruits with both hands and increasing the fruit picking rate.

[0026] 2. This utility model incorporates a net, a shaping ring, and an installation ring. The net is fixedly installed at the end of the flexible tube via the installation ring. When the fruit falls into the net through the flexible tube, the conical net can buffer and slow down the descent of the fruit, reducing damage caused by impact when the fruit falls into the storage box. Furthermore, the bottom of the net is equipped with a shaping ring, which ensures that the bottom of the net always remains round, thereby preventing excessive accumulation of fruit in the net and causing blockage.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figure 1 — Figure 4The system includes a fruit harvester 1, a storage box 2 fixed to the top of the harvester 1, a storage compartment 201 inside the storage box 2, a door panel 202 installed on one side of the storage box 2, a lifting assembly installed on the top of the storage box 2, a lifting platform 4 connected to the top of the lifting assembly, a rotating column 5 movably installed on the top of the lifting platform 4, a conveying assembly inside the rotating column 5, the conveying assembly including a flexible hose 602 connected to the inside of the storage compartment 201, a conveying pipe 601 connected to the top of the flexible hose 602, and a feeding hopper 6 installed at the end of the conveying pipe 601, thus solving the problem of harvesting... To address the issue of low harvesting efficiency when harvesters stand on a movable lifting platform to pick fruit, the lifting assembly raises the lifting platform 4 to a suitable height. Harvesters can then push the connecting rod 504 to rotate and move the feeding hopper 6 near the fruit, making it easier for them to feed the fruit into the feeding hopper 6. After the fruit is placed in the feeding hopper 6, it slides down the inner wall of the feeding hopper 6 into the conveying pipe 601. The fruit in the conveying pipe 601 then falls into the collection bin 201 through the flexible hose 602, allowing harvesters to pick fruit with both hands and increasing the fruit picking rate.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The inner wall of the feeding hopper 6 is funnel-shaped, and the diameter of the inner wall at the top of the feeding hopper 6 is larger than the diameter of the inner wall at the bottom. The funnel-shaped inner wall of the feeding hopper 6 makes it easier for harvesters to place the fruit into the feeding hopper 6.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A fixing sleeve 505 is fitted on the outer wall of the conveying pipe 601. A connecting rod 504 is connected to one side of the fixing sleeve 505. A fixing plate 503 is fixed to the end of the connecting rod 504. Multiple sets of connecting columns 502 are connected to the bottom of the fixing plate 503. The fixing sleeve 505 fixes the feeding hopper 6 and the conveying pipe 601 so that when the harvester places the fruit in the feeding hopper 6, the feeding hopper 6 can withstand the weight of the fruit.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The lifting assembly includes a hydraulic cylinder 3, with a lifting rod 301 connected to the end of the hydraulic cylinder 3. Lifting frames 302 are installed on both sides of the lifting rod 301. The harvester can control the hydraulic cylinder 3 to push the lifting rod 301. The movement of the lifting rod 301 drives the lifting frame 302 to raise the lifting platform 4.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 3The bottom end of the rotating column 5 is located inside the lifting platform 4. The outer wall of the bottom end of the rotating column 5 is fitted with a bearing 501. During the fruit picking process, the picker can push the connecting rod 504 to make the rotating column 5 rotate, so that the feeding bucket 6 rotates and moves to the vicinity of the fruit. The bearing 501 fitted on the outer wall of the rotating column 5 can reduce the rotational resistance of the rotating column 5, thereby facilitating the picker to rotate the feeding bucket 6.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The top of the lifting platform 4 is equipped with a guardrail 506, and the height of the guardrail 506 is lower than the height of the fixed plate 503. The guardrail 506 protects the picking personnel standing on the top of the lifting platform 4 and prevents them from falling while picking fruit.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The hose 602 is made of rubber, and the inner diameter of the hose 602 is larger than the maximum diameter of the fruit. During the lifting process of the lifting platform 4, the rubber hose 602 can be extended, so that the hose 602 can provide a channel between the connecting pipe 601 and the storage box 2.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The inner wall of the storage box 2 is fitted with a mesh bag 7, and the top of the mesh bag 7 is fixed with an installation ring 702. The mesh bag 7 is fixedly installed in the storage box 2 at one end of the hose 602 by the installation ring 702.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall of the net bag 7 is set in a cone shape, and the net bag 7 uses a net with a mesh size of 1cm. A shaping ring 701 is installed at the bottom of the net bag 7. The shaping ring 701 can keep the bottom of the net bag 7 round at all times, thereby preventing the fruit from piling up too much in the net bag 7 and causing blockage.

[0046] Second embodiment:

[0047] Please see Figure 5 The bottom wall of the inner wall of the storage box 2 is inclined. When the fruit falls into the storage compartment 201 through the net bag 7, the fruit will slide down along the inclined bottom wall of the storage box 2 to the vicinity of the door panel 202, which makes it convenient for the pickers to take the fruit out of the storage box 2.

[0048] In practical operation, the following steps are taken: First, the harvester controls the hydraulic cylinder 3 to drive the lifting frame 302 to raise the lifting platform 4 via the lifting rod 301. During the raising of the lifting platform 4, the hose 602 connected to the bottom of the lifting platform 4 extends. Then, the harvester places the harvested fruit into the feeding hopper 6. The fruit slides down the inner wall of the feeding hopper 6 into the conveying pipe 601. The fruit in the conveying pipe 601 falls into the collection bin 201 through the hose 602. When the fruit slides out of the hose 602, the net bag 7 installed at the top of the collection bin 201 buffers and slows down the fruit. Then, the fruit in the net bag 7 falls into the collection box 2 through the hole at the bottom of the net bag 7. During the harvesting process, the harvester can push the connecting rod 504 to make the rotating column 5 rotate, causing the feeding hopper 6 to rotate and move closer to the fruit.
