Description

Technical Field

[0001] This utility model relates to the field of harvester technology, and more specifically, to a high-purity cranberry harvester. Background Technology

[0002] Cranberries are small berries native to North America, primarily growing in acidic peat soils in wetlands or swamps. Their cultivation differs significantly from traditional crops: cranberry vines grow prostrate, producing small, densely packed berries that turn bright red when ripe. Due to the low-growing nature of the plants and their unique growing environment, traditional manual harvesting is extremely inefficient. Even more uniquely, cranberries contain air cavities, allowing them to float in water when ripe. This characteristic is used in "wet harvesting"—by flooding the field and using machinery to separate the berries from the vines, allowing them to float on the surface for collection. This harvesting method relies heavily on mechanized equipment.

[0003] However, current cranberry harvesting mainly relies on manual picking, which is inefficient and has high labor costs.

[0004] Therefore, there is an urgent need for a high-purity cranberry harvester to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, this utility model proposes a high-purity cranberry harvester, aiming to solve the problem of low cranberry harvesting efficiency in existing models.

[0006] This utility model provides a high-purity cranberry harvester, comprising:

[0007] Walking mechanism;

[0008] The platform is located above the walking mechanism and is rotatably connected to the walking mechanism;

[0009] The vehicle body includes a transfer mechanism, a collection mechanism, a harvesting mechanism, a hydraulic mechanism, and a control mechanism. One end of the platform is fixedly connected to the control mechanism, which is used to control the harvester. The right side of the control mechanism is fixedly connected to the collection mechanism, the right side of the collection mechanism is fixedly connected to the transfer mechanism, and the right side of the transfer mechanism is fixedly connected to the harvesting mechanism. The hydraulic mechanism is distributed between the transfer mechanism and the harvesting mechanism to control the angle of the transfer mechanism and the harvesting mechanism.

[0010] Furthermore, the collection mechanism includes a purge cylinder and a collection section. The purge cylinder is connected to the control mechanism and is located on one side of the collection section. The collection section is fixedly connected to the platform panel.

[0011] Furthermore, the collection unit includes a screening box and a collection box. The screening box is divided into a screening area and a collection area. The bottom wall of the screening area is provided with a plurality of screening holes. The collection area is provided below the screening area. The collection box is located in the collection area and is locked in the collection area by a locking assembly.

[0012] Furthermore, the locking assembly includes a locking block and a locking hook. The locking block is rotatably connected to the side wall of the cleaning box, and a locking hook is fixedly connected to the end of the locking block away from the cleaning box.

[0013] Furthermore, the transfer mechanism includes transfer rollers, a conveyor belt, and a transfer frame. One side of the transfer frame is rotatably connected to the platform via the hydraulic mechanism. Several transfer rollers are rotatably connected inside the transfer frame, and the conveyor belt is sleeved on the several transfer rollers.

[0014] Furthermore, the conveyor belt is equipped with several baffles to prevent the cranberries from rolling back.

[0015] Furthermore, the hydraulic mechanism includes a first tilt adjustment cylinder mounted on the transfer frame, a second tilt adjustment cylinder mounted on the acquisition mechanism, and a rotation control cylinder mounted under the platform.

[0016] Furthermore, the collection mechanism includes a collection bucket and a sweeping component, the collection bucket being rotatably connected to the transfer frame, and the sweeping component being located above the collection bucket.

[0017] Furthermore, the control mechanism includes a drive device and a control device. The control device is located on one side of the walking mechanism and is fixedly connected to the platform. The drive device is located inside the control device.

[0018] Furthermore, the walking mechanism includes tracks, guide wheels, a walking motor, and track side beams.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: Through the rotating connection structure between the walking mechanism and the platform, the equipment can adapt to harvesting needs under different terrain conditions. The walking mechanism provides stable movement for the entire equipment, while the rotating characteristics of the platform allow the machine to adjust its center of gravity in complex terrain, reducing the risk of tilting or tipping over due to uneven ground. This structure allows the harvester to operate flexibly in areas difficult for traditional machinery to access, such as wetlands and slopes, increasing the harvesting coverage. Simultaneously, the series layout of the transfer mechanism, harvesting mechanism, and collection mechanism optimizes the path of fruit from harvesting to transfer. The harvesting mechanism directly connects to the vine area, using a hydraulic mechanism to precisely position the fruit by adjusting the angle, reducing unnecessary movement; the transfer mechanism quickly transfers the fruit to the collection mechanism, avoiding the problems of fruit accumulation or omission caused by multiple transfers in traditional equipment, thus shortening the harvesting cycle. The synergistic structure of the harvesting mechanism and the hydraulic mechanism enables gentle picking through angle adjustment. The precise control of the harvesting angle by the hydraulic mechanism avoids excessive pulling on the vines or squeezing of the fruit by traditional rigid machinery, reducing the fruit skin damage rate. For wet harvesting scenarios, this structure can also reduce water turbidity caused by excessive mechanical agitation, thereby reducing subsequent water treatment costs. The fixed connection structure between the collection and transfer mechanisms adopts an integrated guide channel structure, which reduces collisions and friction during fruit transportation, preventing fruit from scattering due to external forces or being contaminated by the outside world, further ensuring harvesting quality.

[0028] See Figure 1-2As shown, this embodiment provides a high-purity cranberry harvester, including: a walking mechanism 1;

[0029] The platform 2 is located above the walking mechanism 1 and is rotatably connected to the walking mechanism 1;

[0030] The vehicle body 3 includes a transfer mechanism 310, a collection mechanism 320, a harvesting mechanism 330, a hydraulic mechanism 340, and a control mechanism 350. One end of the platform 2 is fixedly connected to the control mechanism 350, which is used to control the harvester. The right side of the control mechanism 350 is fixedly connected to the collection mechanism 320, the right side of the collection mechanism 320 is fixedly connected to the transfer mechanism 310, and the right side of the transfer mechanism 310 is fixedly connected to the harvesting mechanism 330. The hydraulic mechanism 340 is distributed between the transfer mechanism 310 and the harvesting mechanism 330 and is used to control the angle of the transfer mechanism 310 and the harvesting mechanism 330.

[0031] Specifically, the walking mechanism 1 is used to drive the harvester to move and can also control the direction. A platform 2 is set on the top of the walking mechanism 1. The platform 2 can not only support the mechanism on the vehicle body 3, but also change direction by rotating. When the harvester is operating, the operation of the harvester is controlled by the control mechanism 350. At the same time, the control mechanism 350 can adjust the angle of the collection mechanism 330 and the transfer mechanism 310 by the hydraulic mechanism 340. First, the cranberries will be collected by the collection mechanism 330, and then moved to the transfer mechanism 310 by the collection mechanism 330. Finally, the transfer mechanism 310 moves them to the collection mechanism 320 for collection.

[0032] Understandably, the seamless connection between cranberry harvesting and collection is achieved through the coordinated operation of the walking mechanism 1, the harvesting mechanism 330, the transfer mechanism 310, and the collection mechanism 320. The walking mechanism 1 provides stable mobility for the equipment, while the rotating connection structure of the platform 2 ensures that the vehicle body 3 can flexibly adjust its direction during movement to adapt to complex terrain. The harvesting mechanism 330 acts directly on the fruit area, and the angle is adjusted by the hydraulic mechanism 340 to reduce unnecessary movement; the transfer mechanism 310 transfers the fruit to the collection mechanism 320, avoiding process interruptions or fruit accumulation caused by multiple transfers in traditional equipment. This integrated process structure shortens the harvesting cycle and improves overall operational efficiency. The hydraulic mechanism 340 controls the angles of the harvesting mechanism 330 and the transfer mechanism 310, making the mechanical movements more gentle and controllable. The harvesting mechanism 330, through angle adjustment, can conform to the growth shape of the vines, avoiding compression or scratching of the fruit by rigid structures; the transfer mechanism 310 adopts a gentle conveying path to reduce collisions and friction of the fruit during movement. Furthermore, the enclosed collection mechanism 320's structure isolates external impurities such as soil and leaves, ensuring the purity of the harvested fruit and meeting the high standards of integrity and cleanliness required by the fresh fruit market. The rotating connection mechanism between the walking mechanism 1 and the platform 2 allows the equipment to dynamically adjust its center of gravity distribution according to ground undulations. In irregular terrains such as wetlands or slopes, the rotating function of the platform 2 can balance the risk of tilting of the vehicle body 3, preventing the equipment from tipping over or sinking due to a shift in the center of gravity. Simultaneously, the linkage structure between the directional control of the walking mechanism 1 and the vehicle body 3 module ensures that the equipment maintains continuity in collection and transfer actions even when turning, avoiding operational interruptions or fruit loss due to directional adjustments.

[0033] In some embodiments of this application, the collection mechanism 320 includes a purge cylinder 321 and a collection section. The purge cylinder 321 is connected to the control mechanism 350, and the purge cylinder 321 is located on one side of the collection section. The collection section is fixedly connected to the platform 2.

[0034] Specifically, the collection section is used to collect cranberries that have been moved from the transfer mechanism 310. The collection is carried out through the collection section, while the blower 321 can be controlled to open and close by the control device 352 to blow away branches, leaves or other debris.

[0035] Understandably, the combined action of the purge cylinder 321 and the collection section effectively separates cranberry fruits from impurities such as twigs and leaves. The purge cylinder 321, selectively activated by the control mechanism 350, uses airflow to directionally remove lightweight debris, preventing it from entering the collection section with the fruit. This physical screening mechanism reduces the impurity contamination rate without relying on complex filtration systems, making it particularly suitable for cleaning fruits that may be covered in mud or rotten leaves during wet harvesting. Simultaneously, the fixed connection structure of the collection section ensures the stability of the fruit during transport, reducing secondary contamination caused by shaking or collisions, and meeting the high standards of the fresh fruit market for fruit appearance integrity and cleanliness. In traditional harvesting processes, collected fruits require additional manual sorting or mechanical sieving to remove impurities. This solution, however, utilizes the instant cleaning function of the purge cylinder 321 to complete preliminary purification simultaneously during harvesting. This "harvest-while-cleaning" model reduces investment in subsequent processing steps and shortens the overall cycle from field to market. In addition, the controllability of the purge tube 321 allows the operator to dynamically adjust the wind intensity or switching frequency according to the actual impurity content, avoiding excessive purging that could cause fruit to scatter or energy to be wasted, thus further optimizing resource utilization efficiency.

[0036] In some embodiments of this application, the collection unit includes a screening box 322 and a collection box 323. The screening box 322 is divided into a screening area and a collection area. The bottom wall of the screening area is provided with a plurality of screening holes 324. The collection area is provided below the screening area. The collection box 323 is located in the collection area and is locked in the collection area by a locking component.

[0037] In some embodiments of this application, the locking assembly includes a locking block 360 and a locking hook 370. The locking block 360 is rotatably connected to the side wall of the cleaning box 322, and the locking hook 370 is fixedly connected to one end of the locking block 360 away from the cleaning box 322.

[0038] Specifically, the area below the screening zone has a hollow structure with space for collecting cranberries that fall through the screening holes 324. Since the harvester may experience bumps during operation, a locking assembly is used to prevent the collecting box 323 from slipping. Existing collecting boxes 323 have grooves on all four sides for easy handling. The locking hooks 370 on the locking block 360 can be hooked into the grooves to prevent the collecting box 323 from slipping. If the collecting box 323 does not have grooves, the locking block 360 can prevent it from sliding out. Since the locking block 360 is rotatably connected to the outer wall of the screening box 322, the locking effect is achieved by rotating the locking block 360.

[0039] Understandably, the partitioned structure of the screening box 322 achieves secondary purification of the harvested fruit through the synergistic effect of the screening and collection zones. The screening holes 324 on the bottom wall of the screening zone filter out fine sand, broken leaves, and other impurities mixed in with the fruit, ensuring that the cranberries entering the collection box 323 are cleaner. This grading and screening mechanism does not rely on external power or complex devices; it completes the initial sorting solely through gravity and mechanical structure, reducing the cleaning burden in subsequent processing stages. Simultaneously, the distribution and size of the screening holes 324 are adapted to the fruit size, preventing fruit from leaking out of the holes and intercepting impurities, further improving the overall quality of the harvested fruit. The locking assembly reduces the risk of the collection box 323 slipping during equipment vibration or turning. The engagement of the locking hook 370 with the groove in the collection box 323 achieves rigid locking, preventing displacement of the box due to inertia; while the rotating connection characteristic of the locking block 360 gives it adaptive adjustment capabilities, allowing it to physically block the edges of the box even if it lacks a groove. This dual-fixation mechanism is particularly important in complex terrains such as wetlands and slopes, preventing fruit loss or equipment damage due to the box detaching, and ensuring the continuity of harvesting operations and personnel safety. The rotating structure design of the locking assembly greatly optimizes the ease of loading and unloading the collection box 323. The operator only needs to rotate the locking block 360 to release the fixing of the collection box 323, without the need for tools or complicated operations, shortening the time for changing empty boxes or unloading.

[0040] In some embodiments of this application, the transfer mechanism 310 includes transfer rollers 311, a conveyor belt 312, and a transfer frame 313. One side of the transfer frame 313 is rotatably connected to the platform 2 via the hydraulic mechanism 340. A plurality of transfer rollers 311 are rotatably connected inside the transfer frame 313, and the conveyor belt 312 is sleeved on the plurality of transfer rollers 311.

[0041] Understandably, the combined structure of the transfer rollers 311 and the conveyor belt 312 achieves efficient transport of fruit from harvesting to collection. The even distribution of multiple transfer rollers 311 ensures that the conveyor belt 312 maintains tension balance during operation, avoiding slippage or deviation caused by local slack. The transfer frame 313 is connected to the platform 2 via a hydraulic mechanism 340, allowing the angle of the conveyor belt 312 to be dynamically adjusted according to the harvesting scenario—for example, tilting it to match the terrain slope when working on slopes, or raising it to accelerate transport when fruit is piled up. Controlling the tilt angle reduces the need for manual intervention, ensures seamless connection of the harvesting process, and shortens the overall operation cycle. The flexible material of the conveyor belt 312 and the smooth surface structure of the transfer rollers 311 reduce collisions and friction of the fruit during transport. Traditional rigid conveyor plates or chain drives are prone to damage to the fruit skin due to vibration or hard contact, while the wrapping support of the conveyor belt 312 in this solution can disperse pressure, especially providing cushioning protection for highly ripe cranberries. Furthermore, the uniform layout of the transfer rollers 311 prevents localized depressions or bulges in the conveyor belt 312, ensuring smooth fruit movement and reducing the risk of fruit falling off or being crushed due to bumps. The hydraulic rotational connection between the transfer frame 313 and the platform 2 gives the equipment dynamic adjustment capabilities. In wetlands or rugged terrain, the hydraulic mechanism 340 can adjust the horizontal tilt angle of the transfer frame 313 in real time, ensuring that the conveyor belt 312 always maintains the optimal docking angle with the collection mechanism 330 and the harvesting mechanism 320, preventing interruptions or jamming of fruit transport due to machine tilting.

[0042] In some embodiments of this application, the conveyor belt 312 is provided with a plurality of baffles 314, which are used to prevent cranberries from rolling back.

[0043] Understandably, the baffles 314 installed on the conveyor belt 312 prevent cranberries from rolling back or shifting due to inertia or incline during transport by providing physical barriers. Especially during equipment uphill, turning, or bumpy operations, the segmented isolation spaces formed by the baffles 314 limit disorderly fruit movement, ensuring they are smoothly transported along a predetermined path to the collection mechanism 320. This directional guidance capability reduces process interruptions caused by fruit accumulation or scattering, ensuring the continuity of harvesting operations. The spaced arrangement of the baffles 314 forms multiple independent load-bearing units on the surface of the conveyor belt 312, dispersing the collision pressure between fruits. In traditional designs without baffles 314, fruits are prone to rolling and squeezing due to vibration or speed changes of the conveyor belt 312, while the limiting effect of the baffles 314 reduces direct friction and collision between fruits, especially protecting highly ripe fruits with fragile skin. Furthermore, the baffles 314 also prevent fruits from rolling back into the gaps between equipment or the ground, reducing accidental losses during harvesting.

[0044] In some embodiments of this application, the hydraulic mechanism 340 includes a first tilt adjustment cylinder mounted on the transfer frame 313, a second tilt adjustment cylinder mounted on the acquisition mechanism 330, and a rotation control cylinder 343 mounted under the platform 2.

[0045] In some embodiments of this application, the collection mechanism 330 includes a collection bucket 331 and a sweeping component 332. The collection bucket 331 is rotatably connected to the transfer frame 313, and the sweeping component 332 is located above the collection bucket 331.

[0046] Understandably, through the coordinated action of the first and second tilt-adjustment cylinders, the equipment can dynamically adjust the harvesting angle according to the vine distribution and terrain undulations. The first tilt-adjustment cylinder controls the tilt angle of the transfer frame 313, ensuring that the connection height between the conveyor belt 312 and the harvesting bucket 331 matches the fruit position; the second tilt-adjustment cylinder adjusts the pitch angle of the harvesting bucket 331, making it precisely fit the vine surface, reducing the misharvesting or missed harvesting of immature fruits. This multi-dimensional angle adjustment enhances the precision of the harvesting action, especially suitable for scenarios with uneven fruit distribution or large differences in plant density. The linkage structure between the rotary control cylinder 343 and the platform 2 gives the equipment flexible steering capabilities. When operating in narrow fields or on slopes, the rotary control cylinder 343 adjusts the rotation angle of the platform 2 to keep the center of gravity of the vehicle body 3 within the support range of the walking mechanism 1, avoiding equipment tilting due to steering imbalance. Meanwhile, the rotating connection design between the harvesting bucket 331 and the transfer frame 313 allows it to adaptively adjust to the terrain under hydraulic drive, ensuring the harvesting mechanism maintains the optimal contact distance with the ground and reducing blind spots caused by uneven ground. The flexible edge design of the harvesting bucket 331, in conjunction with the sweeping component 332, achieves gentle harvesting. The sweeping component 332, located above the harvesting bucket 331, sweeps the fruit from the vine into the bucket through reciprocating or rotating motions, avoiding direct scraping of the fruit by traditional mechanical rake teeth. The tilt adjustment function of the harvesting bucket 331 controls the contact pressure between the sweeping component 332 and the vine, preventing excessive squeezing that could damage the fruit or break the vine. In addition, the smoothness of the hydraulic drive reduces mechanical impact, further protecting the plant roots and soil structure.

[0047] In some embodiments of this application, the control mechanism 350 includes a drive device 351 and a control device 352. The control device 352 is located on one side of the walking mechanism 1 and is fixedly connected to the platform 2. The drive device 351 is located inside the control device 352.

[0048] Understandably, the integrated layout of the control device 352 and the drive device 351 concentrates the core command execution unit on one side of the walking mechanism 1, and achieves physical positioning through a fixed connection with the platform 2. The operator can directly coordinate walking, turning, and harvesting actions via the control device 352 while the equipment is in motion, reducing command delays caused by distributed control of multiple modules. The drive device 351 is built into the vertically stacked structure of the control device 352, reducing the lateral space occupied by the equipment. Traditional distributed layouts require reserving independent installation areas for the drive unit, while this solution reduces the risk of imbalance caused by a top-heavy design by bringing the control mechanism 350 closer to the center of gravity of the walking mechanism 1.

[0049] In some embodiments of this application, the walking mechanism 1 includes a track 110, a guide wheel 120 and a track side beam 130. The guide wheel 120 is rotatably connected to the track 110, and a track side beam 130 is provided on one side of the guide wheel 120.

[0050] Understandably, the introduction of the track 110 structure enhances the equipment's ability to traverse soft terrain such as wetlands and marshes. Compared to wheeled mechanisms, the track 110 distributes the equipment's weight by increasing the ground contact area, reducing the unit pressure on the ground and preventing sinking or slippage due to insufficient soil bearing capacity. The rotating connection structure between the guide wheel 120 and the track 110 ensures that the track 110 is evenly stressed during turning, preventing excessive wear on one side or derailment. The track side beam 130, located on one side of the guide wheel 120, physically blocks mud, gravel, and other debris from entering the track 110, ensuring the cleanliness and operational stability of the transmission system. This combined structure allows the equipment to stably traverse cranberry wetland fields that are difficult for traditional wheeled machinery to access, expanding the coverage area of ​​harvesting operations. The wide contact surface and flexible material of the track 110 reduce damage to the soil structure. Traditional wheeled machinery's concentrated loads can easily compact the soil, damaging the shallow root system of cranberry vines. The distributed load-bearing characteristics of the tracks 110, however, maintain soil porosity, protecting root aeration and water permeability. Furthermore, the edge protection function of the track side beams 130 prevents direct contact between the outer side of the tracks 110 and the vines, avoiding scraping or crushing the plants during transport, especially in high-density planting areas, minimizing mechanical damage to unharvested fruit.

[0051] The ring-shaped double-shell structure of the high-purity cranberry harvester in the above embodiments, through the rotating connection structure between the walking mechanism 1 and the platform 2, allows the equipment to adapt to harvesting needs under different terrain conditions. The walking mechanism 1 provides stable movement for the entire equipment, while the rotational characteristics of the platform 2 allow the vehicle body 3 to adjust the center of gravity distribution in complex terrain, reducing the risk of equipment tilting or tipping over due to uneven ground. This structure enables the harvester to operate flexibly in areas that are difficult for traditional machinery to access, such as wetlands and slopes, increasing the harvesting coverage. At the same time, the series layout of the transfer mechanism 310, the collection mechanism 330, and the collection mechanism 320 optimizes the path of the fruit from collection to transfer. The collection mechanism 330 directly connects to the vine area, and the hydraulic mechanism 340 adjusts the angle to accurately locate the fruit position, reducing unnecessary movement; the transfer mechanism 310 quickly transfers the fruit to the collection mechanism 320, avoiding the problem of fruit accumulation or omission caused by multiple transfers in traditional equipment, and shortening the harvesting cycle. The collaborative structure of the collection mechanism 330 and the hydraulic mechanism 340 enables gentle picking through angle adjustment. The hydraulic mechanism 340 precisely controls the harvesting angle, avoiding excessive pulling on the vines or squeezing the fruit by traditional rigid machinery, thus reducing the fruit's skin damage rate. In wet harvesting scenarios, this structure also reduces water turbidity caused by excessive mechanical agitation, thereby lowering subsequent water treatment costs. The fixed connection structure between the collection mechanism 320 and the transfer mechanism 310 uses an integrated guide channel structure, reducing collisions and friction during fruit transport and preventing fruit from scattering due to external forces or being contaminated, further ensuring harvest quality.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
