Description

Technical Field

[0001] This utility model relates to the technical field of cranberry harvesting equipment, and more specifically, to a cranberry harvester harvesting mechanism with a high harvesting rate. Background Technology

[0002] Cranberries are the fruit of a low-growing shrub that grows in acidic peat soils. They are widely used in juices, dried fruit, condiments, and health products. Traditional manual harvesting relies on labor-intensive "wet harvesting": farmers flood cranberry fields in the fall to create shallow pools, then collect the floating berries manually or with simple tools. This method is inefficient, costly, and limited by seasonal labor shortages. With the increasing global demand for cranberries, mechanization has become an inevitable choice.

[0003] There are three main methods for harvesting cranberries. First, manual harvesting is inefficient and some fruits may remain on the vine. Second, wet mechanical harvesting relies on water flow and the rotating comb rollers do not peel the ripe fruits evenly, making it easy to miss harvesting in low-lying or densely planted areas. Finally, dry mechanical vibration harvesting is inefficient. The existing vibration frequency (usually 800-1200 times / minute) is difficult to balance high drop rate and low damage rate, requiring repeated operations. In addition, the harvesting tools of existing mechanical harvesting equipment are usually one-piece structures, and when one part is damaged, the entire harvesting tool needs to be disassembled and replaced.

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

[0011] Furthermore, the cutting part (340) includes a cutting groove (3401) and a cutting blade (3402). The cutting groove (3401) is a triangular groove, located between the two picking blades (3202) and on one side of the collection group (310).

[0012] Furthermore, the locking part (350) includes a locking block (3501), locking holes (3502), and locking bolts (3503). The locking block (3501) is fixedly connected to the picking group. Both the locking block (3501) and the storage compartment (1) are provided with a plurality of locking holes (3502) along the length direction. The locking bolts (3503) lock the locking block (3501) and the storage compartment (1) through the plurality of locking holes (3502).

[0013] Furthermore, the drive assembly (410) includes a drive shaft (4101), a drive plate (4102), and a drive head (4103). The drive shaft (4101) is located above the storage compartment (1) and is rotatably connected to the guard plate (2). A plurality of drive plates (4102) are fixedly connected to the drive shaft (4101). The plurality of drive plates (4102) are circular and rotate coaxially with the drive shaft (4101). A plurality of drive heads (4103) are provided on the plurality of drive plates (4102).

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model achieves compactness and efficiency of functional modules through the coordinated structure of the storage compartment, protective plate, locking part, and sweeping part. The protective integration of the storage compartment and protective plate improves the integrity of fruit collection. The protective plates on both sides of the storage compartment form a physical barrier, preventing fruit from splashing outside the work area due to mechanical movement or external interference, reducing accidental losses during harvesting, and enhancing structural stability. The rigid connection between the protective plate and the storage compartment provides support for the overall mechanism, reducing the risk of equipment displacement due to uneven ground or mechanical vibration, ensuring the accuracy of the collection path, and the protective plate can also protect the collection mechanism. The quick assembly and disassembly of the collection mechanism and storage compartment through the locking device facilitates the adjustment of equipment layout according to different field terrains (such as peatlands and slopes), optimizing space utilization. At the same time, the modular structure allows key components (such as the sweeping part and collection mechanism) to be disassembled and repaired independently, reducing overall downtime due to local failures. The sweeping part, through the coaxial linkage structure between the drive component and the sweeping part, forms a continuous and stable fruit collection action, optimizing the operation process. The synergistic effect of the drive component and the sweeping component improves the efficiency of fruit peeling and collection. When the sweeping component rotates coaxially with the drive component, its motion trajectory covers a wide range and the action is continuous. It can simultaneously complete fruit peeling, sweeping and gathering, reducing process redundancy in traditional step-by-step operations, while reducing physical damage to the plants. The mechanical distribution of the rotating sweeping action is more uniform. Compared with the impact peeling of traditional machinery, it can reduce the pulling and damage to cranberry vines, maintain the health of the plants, and the rotational motion of the sweeping part can adapt to scenarios with uneven vine density or scattered fruit distribution. By continuously sweeping to cover blind spots, it reduces missed harvesting. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] See Figure 1-5 As shown, this embodiment provides a cranberry harvester collection mechanism 3 with a high harvesting rate, including: a storage compartment 1, and protective plates 2 are fixedly connected to both sides of the storage compartment 1;

[0030] The collection mechanism 3 is located on one side of the storage compartment 1, and the collection mechanism 3 is locked to the storage compartment 1 through the locking part 350. The collection mechanism 3 includes a collection group 310, and a plurality of collection groups 310 are provided. Each collection group 310 is provided with a plurality of collection blade assemblies 320. There is a collection gap 330 between the plurality of collection blade assemblies 320, and a cutting part 340 is provided on the collection gap 330.

[0031] The sweeping unit 420 includes a drive assembly 410 and a sweeping assembly 4. The drive assembly 410 is rotatably connected to the guard plate 2, and the sweeping assembly 4 is sleeved on the drive assembly 410 and rotates coaxially with the drive assembly 410.

[0032] Specifically, the storage chamber 1 is used to store the cranberries collected by the collection mechanism 3. When the collection mechanism 3 collects cranberries, the berries roll into the storage chamber 1 along with the collection mechanism 3. Then, the drive component 410 in the sweeping part 420 rotates, driving the sweeping component 4 to rotate coaxially, thereby sweeping the berries in the storage chamber 1 to the subsequent storage box for collection. The storage chamber 1 is horizontally arranged with several collection groups 310 along its length. Each collection group 310 is equipped with several collection blade components 320. There is a collection gap 330 between each collection blade component 320. The cutting part 340 is located at the connection between the collection blade component 320 and the collection group 310. Even if one collection group 310 is damaged during use, it will not affect the operation of the other collection groups 310, and there is no need to replace all collection groups 310.

[0033] Understandably, the collection mechanism 3, through the interconnected structure of the storage chamber 1, the protective plate 2, the collection mechanism 3, and the sweeping unit 420, constructs an efficient and stable fruit collection system. The storage chamber 1, as the core storage unit, forms a semi-enclosed structure with the protective plate 2, constraining the fruit's movement trajectory and preventing fruit scattering due to mechanical vibration or external interference. The rigid connection of the protective plate 2 not only enhances the overall stability of the equipment but also provides reliable support for the sweeping unit 420, ensuring the continuity of power transmission. The collection mechanism 3 and storage bin 1 are quickly connected via locking part 350, which simplifies the equipment assembly process, ensures the positioning accuracy of key components during operation, and reduces harvesting efficiency loss due to structural loosening. During operation, the collection mechanism 3 directly guides the peeled cranberries into the storage bin 1 through a rolling motion, reducing the intermediate steps of multiple fruit transfers in traditional machinery and lowering the risk of fruit damage due to collision or friction. The semi-enclosed structure of the storage bin 1 can temporarily store a large number of fruits, forming a buffer space to avoid downtime due to full load of subsequent processing equipment, thus maintaining the continuity of harvesting operations. When the sweeping component 4 rotates coaxially with the drive component 410, its movement trajectory covers the lateral space of the storage bin 1, and the scattered fruits are concentrated and guided to the subsequent storage box through rotational sweeping. This dynamic collection method improves the uniformity and thoroughness of fruit collection compared to static scrapers or manual intervention. Furthermore, the mechanical properties of the rotary sweeping mechanism can adapt to changes in fruit bulk density. For example, centrifugal force accelerates diffusion in densely populated areas, while centripetal force strengthens aggregation in sparsely populated areas, thereby reducing residue in the storage chamber and increasing the fruit recovery rate per operation. The protective plate 2 forms a physical barrier around the storage chamber 1, preventing impurities such as mud and broken leaves from intruding into key transmission components (such as the bearings of the drive assembly 410), reducing the risk of mechanical jamming or wear, and extending the equipment's service life. The coaxial connection between the sweeping assembly 4 and the drive assembly 410 reduces intermediate links in traditional belt or chain drives, avoiding power interruption problems caused by slippage or breakage of transmission components, and improving the equipment's reliability in wet and muddy environments. The locking part 350 allows for quick assembly and disassembly of the collection module and the storage chamber 1, facilitating adjustments to the equipment layout according to the field terrain (such as slopes and depressions). For example, the equipment width can be reduced in narrow areas, while components can be expanded in flat areas to increase the coverage of a single operation. Multiple collection groups 310 reduce the impact of local failures on the overall system. These groups are distributed laterally along the storage compartment 1, with each group operating independently. If one group is damaged due to obstruction by foreign objects or mechanical wear, the remaining groups can still operate normally, avoiding the complete shutdown problem caused by a single point of failure in traditional integrated structures. Damaged collection groups 310 can be disassembled and replaced individually without replacing the entire collection mechanism 3, saving spare parts costs, shortening maintenance cycles, and ensuring the continuity of harvesting operations. The distributed structure of multiple collection groups 310 disperses the mechanical load, avoiding fatigue damage caused by concentrated stress on a single component over a long period, thus delaying the overall aging of the equipment.Redundant collection units 310 can work collaboratively in high-density fruit areas, sharing the workload and reducing the risk of overload operation. Collection blade components 320 form staggered cutting units through collection gaps 330, capable of cutting fruit stalks upon contact with the vines, reducing pressure damage to the fruit and preventing excessive entanglement of mechanical parts by the vines. Cutting sections 340, located at the connection points of the collection blade components 320, can simultaneously cut mixed vine tendrils or leaves during fruit peeling, reducing the burden of impurity handling in subsequent sorting stages. Collection gaps 330 allow the vines to spread naturally during cutting, avoiding mechanical jamming or blockage caused by vine accumulation in densely planted areas, improving the equipment's maneuverability in complex planting environments.

[0034] In some embodiments of this application, the harvesting blade assembly 320 includes a reinforcing rib 3201, a harvesting blade 3202, and a harvesting head 3203. The harvesting blade 3202 is fixedly connected to the locking part 350, and each harvesting blade 3202 is evenly distributed on the harvesting assembly. The harvesting blade 3202 is wavy. The side of the harvesting blade 3202 near the locking part 350 is fixedly connected to the reinforcing rib 3201. The end of the harvesting blade 3202 away from the locking part 350 is provided with a harvesting head 3203, which is a semi-circular protrusion.

[0035] In some embodiments of this application, the cutting part 340 includes a cutting groove 3401 and a cutting blade 3402. The cutting groove 3401 is a triangular groove, located between the two picking blades 3202, and on one side of the collection group 310.

[0036] Understandably, the reinforcing rib 3201 at the connection between the picking blade 3202 and the locking part 350, through localized thickening or reinforcement, enhances the bending resistance of the picking blade 3202 during high-speed operation and reduces the risk of deformation due to repeated stress. The longitudinal distribution of the reinforcing rib 3201 complements the wavy profile of the picking blade 3202 mechanically, dispersing concentrated stress during cutting while maintaining the overall rigidity of the blade edge, ensuring structural reliability under prolonged high-intensity operation. The wavy blade edge, through its undulating surface, creates a multi-point contact pattern, generating alternating shearing forces when cutting vines. Compared to a traditional straight blade edge, this reduces blade edge curling or chipping caused by single-point overload.

[0037] The wavy design expands the contact area between the blade and the vine, improving cutting efficiency at the same operating speed while reducing dynamic fluctuations caused by localized obstruction. The picking head 3203 features a semi-circular protrusion design; the smooth transition of the curved surface reduces hard contact with the fruit, avoiding scratches on the fruit's surface or internal compression damage that could occur with traditional sharp-angled or flat-headed structures. When inserted into the vine, the semi-circular head guides the vine naturally into the cutting area through an arc, reducing pulling damage to the plant and maintaining the integrity of the vine's root system to support subsequent growth. The triangular groove structure of the cutting groove 3401 creates a "funnel effect," guiding scattered vines towards the area of ​​action of the cutting blade 3402 during operation, preventing missed cuts or entanglement caused by lateral vine displacement. The beveled sides of the triangle disperse the reaction force during vine cutting, reducing lateral impact on the blade and extending the service life of the cutting blade 3402.

[0038] In some embodiments of this application, the locking part 350 includes a locking block 3501, a locking hole 3502, and a locking bolt 3503. The locking block 3501 is fixedly connected to the picking group. Both the locking block 3501 and the storage compartment 1 are provided with a plurality of locking holes 3502 along the length direction. The locking bolt 3503 locks the locking block 3501 and the storage compartment 1 through the plurality of locking holes 3502.

[0039] Understandably, the locking block 3501 and the several locking holes 3502 distributed along the length of the storage compartment 1 form a multi-level fixing node, allowing the lateral installation position of the harvesting assembly to be adjusted according to operational needs. For example, in narrow fields, the spacing between components can be shortened to adapt to the terrain, while in wide areas, the spacing can be extended to increase the coverage of a single operation. The multi-hole design supports asymmetrical layouts to address scenarios with uneven vine distribution or interference from local obstacles, avoiding the rigidity of mechanical layouts caused by traditional single-point locking. The fixed connection between the locking block 3501 and the harvesting assembly concentrates the stress point on rigid components, reducing the risk of mechanical vibration or deformation caused by cantilever effects. The uniform distribution of the locking bolts 3503 achieves distributed load transfer, avoiding structural fatigue caused by local stress concentration and extending the service life of critical connection parts. The standardized fit design of the locking bolts 3503 and the locking holes 3502 simplifies the installation process, allowing operators to complete the positioning and fixing of components without special tools, shortening equipment assembly or modification time. When the locking block 3501 or storage compartment 1 is partially damaged (such as worn threads in the locking hole 3502), only the damaged part needs to be replaced, rather than the entire structure, reducing maintenance costs and resource waste. The independent detachable feature of the locking bolt 3503 facilitates targeted replacement of rusted or deformed parts, avoiding the complex maintenance process of cutting the entire structure required by traditional welded or riveted structures.

[0040] In some embodiments of this application, the drive assembly 410 includes a drive shaft 4101, a drive plate 4102, and a drive head 4103. The drive shaft 4101 is located above the storage compartment 1 and is rotatably connected to the guard plate 2. A plurality of drive plates 4102 are fixedly connected to the drive shaft 4101. The plurality of drive plates 4102 are circular and rotate coaxially with the drive shaft 4101. A plurality of drive heads 4103 are provided on the plurality of drive plates 4102.

[0041] Understandably, the rotational connection between the drive shaft 4101 and the guard plate 2 forms a rigid support structure, ensuring that the drive plate 4102 maintains coaxial motion during rotation, avoiding power fluctuations or energy loss caused by eccentric rotation. The symmetrical design of the circular drive plate 4102 ensures uniform distribution of centrifugal force during rotation, reducing mechanical vibration caused by uneven mass and improving the smoothness of power transmission. The distributed layout of the drive head 4103 on the circular drive plate 4102 forms multi-level action points, generating continuous and staggered power output during rotation, expanding the range of action on fruits or vines, and reducing blind spots. The periodic contact pattern of the drive head 4103 can disperse the impact load on a single point, reducing fatigue damage to mechanical components caused by local overload. The layout of the drive assembly 410 above the storage compartment 1 reduces direct contact with ground mud and debris, lowering the risk of corrosion to transmission components in a humid environment.

[0042] In some embodiments of this application, the sweeping assembly 4 includes a fastening part, a sweeping plate 4205, and sweeping components 4206. The fastening part is fixedly connected to a plurality of the driving heads 4103, the sweeping plate 4205 is connected to the fastening part, and a plurality of sweeping components 4206 are provided on the sweeping plate 4205.

[0043] In some embodiments of this application, the fastening part includes a fastening plate 4201, a fastening groove 4202, a fastening hole 4203, and a fastening bolt 4204. The fastening plate 4201 has a fastening groove 4202 on one side, and the size of the fastening groove 4202 corresponds to the size of the sweeping plate 4205. Both the fastening plate 4201 and the sweeping plate 4205 have a plurality of fastening holes 4203. The fastening bolt 4204 cooperates with the fastening holes 4203 to fasten the fastening plate 4201 and the sweeping plate 4205.

[0044] Understandably, the standardized interface formed by the mate between the sweeping plate 4205 and the fastening groove 4202 allows for quick installation or removal of the sweeping plate 4205 along the direction of the drive head 4103, facilitating adjustments to the sweeping range according to operational needs. The multi-point distribution of the fastening holes 4203 supports localized fine-tuning of the sweeping plate 4205, such as tilting it to accommodate the special scenario of vines growing at an angle, enhancing the equipment's adaptability to complex planting environments. The rigid connection between the fastening plate 4201 and the sweeping plate 4205 evenly transmits the operational reaction force of the sweeping component 4206 to the drive assembly 410, avoiding the risk of deformation or breakage caused by localized stress concentration. The limiting function of the fastening groove 4202 ensures that the sweeping plate 4205 maintains a preset angle during high-speed rotation, reducing displacement deviations caused by vibration or centrifugal force and maintaining the accuracy of the sweeping trajectory. The even distribution of sweeping components 4206 on the sweeping plate 4205 forms a multi-level sweeping unit. Through rotation, it produces a continuous and staggered sweeping effect, expanding the coverage area of ​​a single operation and reducing blind spots present in traditional single-row sweeping structures. Individual sweeping plates 4205 or sweeping components 4206 can be independently disassembled and replaced using fastening bolts 4204, eliminating the need to scrap the entire sweeping assembly 4, thus reducing spare parts costs and resource waste.

[0045] In some embodiments of this application, the included angle between each adjacent scanning plate 4205 is 90°.

[0046] Understandably, the adjacent sweeping plates 4205 are arranged at a 90° angle, forming alternating sweeping units that cover the front and rear main directions during rotation, eliminating the linear blind spots of traditional unidirectional or symmetrical sweeping plates 4205. The superposition effect of multi-directional sweeping trajectories allows for multiple sweeps of the same area, ensuring that loose fruits or fruits hidden at the bottom of the vines are fully gathered, reducing the probability of missed harvesting. The alternating action of the sweeping plates 4205 during rotation forms a continuous sweeping flow, avoiding fruit rebound or secondary dispersion caused by sweeping intervals, maintaining the continuity of the collection process. The mechanical complementarity of the angled layout can counteract the reaction force generated by sweeping in a single direction, reducing equipment travel resistance and improving operational smoothness.

[0047] The high-harvest cranberry harvester collection mechanism in the above embodiments achieves compactness and efficiency of functional modules through the coordinated structure of the storage compartment, protective plates, locking parts, and sweeping parts. The protective integration of the storage compartment and protective plates improves the integrity of fruit collection. The protective plates on both sides of the storage compartment form a physical barrier, preventing fruit from splashing outside the work area due to mechanical movement or external interference, reducing accidental losses during harvesting, and enhancing structural stability. The rigid connection between the protective plates and the storage compartment provides support for the overall mechanism, reducing the risk of equipment displacement due to uneven ground or mechanical vibration, ensuring the accuracy of the collection path, and the protective plates also protect the collection mechanism. The quick assembly and disassembly of the collection mechanism and storage compartment through the locking device facilitates adjustments to the equipment layout according to different field terrains (such as peatlands and slopes), optimizing space utilization. Simultaneously, the modular structure allows key components (such as the sweeping components and collection mechanism) to be independently disassembled and repaired, reducing overall downtime due to partial failures. The sweeping part, through the coaxial linkage structure of the drive component and the sweeping component, forms a continuous and stable fruit collection action, optimizing the work process. The synergistic effect of the drive component and the sweeping component improves the efficiency of fruit peeling and collection. When the sweeping component rotates coaxially with the drive component, its motion trajectory covers a wide range and the action is continuous. It can simultaneously complete fruit peeling, sweeping and gathering, reducing process redundancy in traditional step-by-step operations, while reducing physical damage to the plants. The mechanical distribution of the rotating sweeping action is more uniform. Compared with the impact peeling of traditional machinery, it can reduce the pulling and damage to cranberry vines, maintain the health of the plants, and the rotational motion of the sweeping component can adapt to scenarios with uneven vine density or scattered fruit distribution. By continuously sweeping to cover blind spots, it reduces missed harvesting.

[0048] 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.
