Abstract
Description
Technical Field
[0001] This invention relates to the field of fruit bagging equipment technology, and more specifically to a sorting ramp mechanism and fruit bagging equipment. Background Technology
[0002] In the modern production and distribution chain of the fruit industry, fruit sorting is a crucial link in ensuring product quality grading, enhancing market value, and meeting consumer demand. As consumer markets increasingly demand consistency in fruit quality and more refined grading, and as large-scale fruit cultivation leads to a surge in yields, traditional fruit sorting methods are gradually becoming inadequate for the industry's development needs, highlighting their technological bottlenecks and application limitations.
[0003] Currently, the mainstream fruit sorting methods in the market are mainly divided into two categories: rotary automatic sorting equipment and manual sorting. While rotary automatic sorting equipment possesses a certain degree of automation, its technical design has inherent flaws: this type of equipment typically relies on a single mechanical transmission structure to drive the turntable, and during the sorting process, it uses fixed size detection modules or weight sensors for grading. It cannot accurately identify and differentiate fruit's external defects (such as spots, scratches, and deformities) or internal qualities (such as sugar content and ripeness), resulting in limited sorting accuracy. Furthermore, the number of sorting channels in rotary equipment is fixed, and the operating speed is difficult to adjust flexibly according to fruit type (such as the difference in conveying requirements between soft berries and firm apples), easily leading to problems such as fruit congestion and damage from bumps and knocks, further restricting the improvement of sorting efficiency.
[0004] While manual sorting allows for a comprehensive assessment of fruit quality through visual and tactile senses and remains applicable in small-batch, high-value fruit sorting scenarios, it suffers from significant limitations. Firstly, manual sorting relies on the experience and subjective judgment of operators; differing understandings of quality standards among individuals can lead to inconsistent sorting results, failing to meet the standardization requirements of large-scale production. Secondly, the efficiency of manual sorting is limited by the physical strength and speed of personnel; the daily throughput of a single manual sorting line is typically only 1 / 3 to 1 / 2 that of automated equipment, and prolonged operation can cause fatigue, further reducing efficiency and accuracy. Furthermore, manual sorting requires substantial labor costs, and with rising labor costs, its cost disadvantages become increasingly apparent, making it unsuitable for the production capacity demands of large-scale fruit plantations and processing enterprises.
[0005] In summary, existing fruit sorting methods generally suffer from a core problem of low automation. Rotary automatic sorting equipment can only automate the detection of some physical parameters and lacks intelligent identification capabilities for multi-dimensional quality, while manual sorting relies entirely on human operation. As a result, both sorting methods face the dilemma of low sorting efficiency and insufficient capacity, making it difficult to meet the current development needs of the fruit industry for large-scale, refined, and efficient development. There is an urgent need for a fruit sorting technology solution that can break through the limitations of existing technologies and achieve high automation, high precision, and high efficiency to promote the technological upgrading of the fruit industry's sorting process. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sorting and climbing mechanism and a fruit bagging device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, embodiments of the present invention provide a sorting and climbing mechanism, comprising: a frame, wherein a plurality of feeding components are arranged side by side and at an angle, and a drive component is connected to the frame, wherein the drive component is throttlely connected to all the feeding components so that all the feeding components move synchronously.
[0008] In one specific embodiment, the feeding assembly includes a feeding frame, a main feeding drive, a secondary feeding drive, and a conveyor belt. The feeding frame is connected to the machine frame, the main feeding drive is connected to the top of the feeding frame, the secondary feeding drive is connected to the bottom of the feeding frame, the main feeding drive is drivenly connected to the drive assembly, one end of the conveyor belt is sleeved on the main feeding drive, and the other end is sleeved on the secondary feeding drive.
[0009] In one specific embodiment, the conveyor belt is provided with a plurality of barrier blocks along its length, and a discharge bin is formed between adjacent barrier blocks.
[0010] In one specific embodiment, the barrier block is adhered to the upper surface of the conveyor belt, and the length of the barrier block is adapted to the width of the conveyor belt.
[0011] In one specific embodiment, the cross-section of the barrier block is arc-shaped.
[0012] In one specific embodiment, the feeding rack is provided with upward-facing blocking plates on both sides of the conveyor belt.
[0013] In one specific embodiment, the tilt angle of the conveyor belt is 15 degrees to 35 degrees.
[0014] In one specific embodiment, the drive assembly includes a drive motor and a power transmission component. The drive motor is fixedly connected to the frame, and one end of the power transmission component is drivenly connected to the drive motor, while the other end is drivenly connected to the main feeding transmission component.
[0015] In one specific embodiment, both the conveyor belt and the barrier block are made of flexible material.
[0016] The sorting and climbing mechanism of this invention has the following advantages compared with the prior art: Through the transmission connection between the drive component and all feeding components, synchronous movement of all feeding components can be achieved. This eliminates the need for manual feeding of fruits one by one; simply placing the fruits to be sorted into the parallel feeding components allows for automated transfer from the sorting starting point to the subsequent inspection / grading stage through synchronous tilting conveying. This design eliminates reliance on manual labor in the feeding process and avoids interruptions in conveying due to fruit accumulation in a single feeding channel, significantly improving the continuity of the sorting process and laying the foundation for efficient subsequent sorting. Furthermore, the structure of several feeding components arranged side-by-side effectively expands multiple parallel feeding channels within the same time dimension. Compared to a single feeding channel, multi-channel parallel conveying allows the fruit feeding volume per unit time to increase proportionally with the number of feeding components. Simultaneously, the synchronous movement driven by the drive component ensures consistent conveying speeds in each channel, preventing fruit accumulation or leakage due to speed differences between channels, further guaranteeing high conveying efficiency.
[0017] Secondly, embodiments of the present invention provide a fruit bagging device, including the sorting and climbing mechanism as described above.
[0018] The fruit bagging equipment of this invention has the following advantages compared with the prior art: By setting up a sorting and climbing mechanism and utilizing the transmission connection between the drive component and all feeding components, the synchronous movement of all feeding components can be achieved. This eliminates the need for manual feeding of fruit one by one; instead, the fruit to be sorted is simply placed in batches into the parallel feeding components. The synchronous tilting conveyor of the components completes the automated transfer of fruit from the sorting starting point to the subsequent inspection / grading stage. This design eliminates the reliance on manual labor in the feeding process and avoids interruptions in the conveying process caused by fruit accumulation in a single feeding channel, significantly improving the continuity of the sorting process and laying the foundation for efficient subsequent sorting. Furthermore, the structure of several feeding components arranged side-by-side is equivalent to expanding multiple parallel feeding channels in the same time dimension. Compared to a single feeding channel, multi-channel parallel conveying allows the fruit feeding volume per unit time to increase proportionally with the number of feeding components. Simultaneously, the synchronous movement driven by the drive component ensures consistent conveying speeds in each channel, preventing fruit accumulation or leakage due to speed differences between channels, further guaranteeing high conveying efficiency.

In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
[0029] See Figures 1 to 3 As shown, the present invention discloses a specific embodiment of a sorting ramp mechanism, including: a frame 10, wherein a plurality of feeding components 20 are arranged side by side and inclined on the frame 10, and a drive component 30 is connected to the frame 10. The drive component 30 is tractively connected to all the feeding components 20 so that all the feeding components 20 move synchronously.
[0030] Specifically, the frame 10, serving as the supporting foundation for the entire sorting and climbing mechanism, is welded from aluminum alloy profiles with a rectangular hollow cross-section, ensuring structural strength while reducing overall weight. The bottom of the frame 10 is fixed to the ground with expansion bolts, and the top is welded with parallel mounting rails along the inclined direction (the inclination angle is set between 15° and 30°, which can be finely adjusted within ±5° using the adjustable feet at the bottom of the frame 10). The spacing between the rails is adapted to the width of the feeding assembly 20, allowing for the detachable installation of the feeding assembly 20. Simultaneously, the frame 10 has reserved installation space for the drive assembly 30, with reinforcing ribs welded to the inner wall of this space to prevent deformation of the frame 10 due to vibrations generated during the operation of the drive assembly 30.
[0031] The feeding assembly 20 can be set to 6 sets (the number can be increased or decreased according to the sorting capacity requirements). Each feeding assembly 20 can include a conveyor belt 24, two side baffles and support rollers. The conveyor belt 24 is made of food-grade silicone material (with anti-slip texture on the surface). The baffles are transparent acrylic sheets (80mm high to prevent fruit from falling during transportation). The support rollers are connected to the mounting rail of the frame 10 through bearings, so that each feeding assembly 20 can be disassembled independently along the rail. The 6 feeding assemblies 20 are arranged side by side along the inclined direction of the frame 10, with a spacing of 120mm between adjacent sets, to ensure that the fruit is transported independently in each assembly without interference. At the same time, the width of the conveyor belt 24 of each feeding assembly 20 is set to 200mm, which is suitable for the size of most common fruits (such as citrus, pears, peaches, etc.).
[0032] The drive assembly 30 may include a servo motor, a reducer, a drive gear, a driven gear, and a synchronous chain. The servo motor and the reducer are connected by a coupling. The output end of the reducer is fixed to the drive gear. The driven gears are set corresponding to the support rollers of each feeding assembly 20, and all driven gears are of the same specification. The synchronous chain surrounds the drive gear and all driven gears to form a closed transmission structure. At the same time, a dust cover is set on the outside of the chain to prevent fruit residue and dust from entering and affecting the transmission. In addition, the drive assembly 30 is also equipped with a PLC control system, which can set the motor speed through a touch screen, thereby adjusting the conveying speed of the feeding assembly 20. The system also has an overload protection function. When a feeding assembly 20 is blocked and the load is too large, the motor will automatically stop to prevent damage to the components.
[0033] In other words, through the transmission connection between the drive component 30 and all the feeding components 20, the synchronous movement of all the feeding components 20 can be achieved. This eliminates the need for manual feeding of each fruit individually; instead, fruits to be sorted are simply placed in batches into the parallel feeding components 20. The synchronized tilting conveying of these components automates the transfer of fruit from the sorting starting point to the subsequent inspection / grading stages. This design eliminates reliance on manual labor in the feeding process and avoids interruptions caused by fruit accumulation in a single feeding channel, significantly improving the continuity of the sorting process and laying the foundation for efficient subsequent sorting. Furthermore, the structure of several feeding components 20 arranged side-by-side effectively expands multiple parallel feeding channels within the same time dimension. Compared to a single feeding channel, parallel conveying across multiple channels allows the amount of fruit fed per unit time to increase proportionally with the number of feeding components 20. Simultaneously, the synchronous movement driven by the drive component 30 ensures consistent conveying speeds across channels, preventing fruit accumulation or leakage due to speed differences between channels, further guaranteeing high conveying efficiency.
[0034] In one embodiment, the feeding assembly 20 includes a feeding frame 21, a main feeding drive 22, a secondary feeding drive 23, and a conveyor belt 24. The feeding frame 21 is connected to the frame 10. The main feeding drive 22 is connected to the top of the feeding frame 21. The secondary feeding drive 23 is connected to the bottom of the feeding frame 21. The main feeding drive 22 is drively connected to the drive assembly 30. One end of the conveyor belt 24 is sleeved on the main feeding drive 22, and the other end is sleeved on the secondary feeding drive 23.
[0035] Specifically, the top and bottom of the feeding rack 21 are welded with "L"-shaped mounting plates, and the mounting plates have waist-shaped holes. They are detachably connected to the inclined guide rail of the frame 10 by bolts. The waist-shaped holes allow for fine-tuning of the position of the feeding rack 21 along the length of the guide rail by ±10mm. At the same time, three sets of evenly spaced support bushings are welded on the inner side of the feeding rack 21 to assist in supporting the rotating shafts of the main feeding transmission component 22 and the driven feeding transmission component 23.
[0036] The main feeding transmission component 22 serves as the power input end and includes a drive shaft, a drive sprocket, and a bearing housing. One end of the drive shaft is fixed to the drive sprocket (which is adapted to the synchronous chain of the drive assembly 30) via a flat key, and the other end passes through the support bushing of the feeding frame 21 and is connected to the bearing housing via a deep groove ball bearing. The bearing housing is fixed to the mounting plate at the top of the feeding frame 21 by bolts. At the same time, a locking washer and a nut are provided at the mating point between the drive shaft and the drive sprocket to prevent the sprocket from loosening during high-speed operation. An arc-shaped dust cover is provided on the outside of the drive sprocket, and wool felt is pasted on the inner wall of the dust cover, which can prevent fruit residue and dust from entering the sprocket meshing point without affecting the chain transmission. The driven end of the feed transmission component 23 includes a driven shaft, a driven roller, and a tensioning mechanism. The middle part of the driven shaft is fixed to the driven roller by an interference fit. Both ends of the driven shaft are connected to the tensioning mechanism by sliding bearings. The tensioning mechanism includes a slider and an adjusting screw. The slider is embedded in the groove at the bottom of the feed rack 21. One end of the adjusting screw is threaded to the slider, and the other end passes through the side rod of the feed rack 21. The adjustment is achieved by rotating the screw through a handwheel, which can drive the slider to move up and down along the groove, thereby changing the center distance between the driven roller and the drive sprocket.
[0037] The conveyor belt 24 is made of food-grade PVC material, and polyester warp and weft yarns are woven inside the belt body to enhance the tensile strength of the conveyor belt 24. The surface of the conveyor belt 24 is pressed with diamond anti-slip texture, and the two ends of the belt body are heat vulcanized joints to form a ring structure without joints. When the conveyor belt 24 is fitted on the outside of the drive sprocket of the main feeding drive component 22 and the driven roller of the driven feeding drive component 23, the inner side of the belt engages with the tooth groove of the drive sprocket, the outer anti-slip texture faces upward, and the distance between the edge of the conveyor belt 24 and the vertical bar of the feeding frame 21 is controlled within 5mm.
[0038] In one embodiment, the conveyor belt 24 is provided with a plurality of barrier blocks 25 along its length, and a discharge bin is formed between adjacent barrier blocks 25.
[0039] Specifically, the barrier block 25 is made of the same food-grade PVC material as the conveyor belt 24, and has an overall "trapezoidal" structure. The width of the base surface that is in contact with the conveyor belt 24 is set at 30mm (to ensure the bonding area with the conveyor belt 24 and improve stability), the width of the top is set at 20mm (to reduce lateral pressure on the fruit), and the height is set at 25mm (higher than the surface of the conveyor belt 24, which can prevent common fruits such as citrus, apples, and peaches from sliding). The barrier blocks 25 are evenly distributed along the length of the conveyor belt 24, and the distance between adjacent barrier blocks 25 is set at 120mm (to reserve enough space to accommodate the mainstream fruit size range of 10-80mm in diameter and avoid fruit stacking in a single compartment).
[0040] In other words, when traditional inclined conveyor belts 24 transport fruit, the fruit is prone to sliding and stacking due to gravity along the conveying direction, resulting in "multiple fruit overlapping transport," which affects the accuracy of subsequent sorting and inspection (such as visual inspection failing to identify defects in overlapping fruit). However, the feeding bins, through the physical separation of the blocking blocks 25, confine the fruit to an independent space. Even if the conveyor belt 24 is inclined at an angle of 30°, the fruit will not slide or stack across bins, achieving "one fruit per bin / one batch per bin orderly transport." This provides the basic condition for "independent delivery of single fruit" for subsequent grading and inspection, improving the accuracy of sorting and inspection.
[0041] In one embodiment, the barrier block 25 is adhered to the upper surface of the conveyor belt 24, and the length of the barrier block 25 is adapted to the width of the conveyor belt 24.
[0042] Specifically, through food-grade polyurethane adhesive and pretreatment processes, the barrier block 25 and the conveyor belt 24 form an "integrated" structure. The barrier block 25 remains secure and does not detach, reducing equipment maintenance frequency and component replacement costs, and improving the stability of continuous operation of the device. In addition, the length of the barrier block 25 is adapted to the actual width of the conveyor belt 24, and the two side edges of the barrier block 25 are flush with the two side edges of the conveyor belt 24 (error ≤ 0.5mm), preventing the barrier block 25 from being shorter than the width of the conveyor belt 24, which would cause "fruit to leak out from the side gaps of the conveyor belt 24".
[0043] In one embodiment, the cross-section of the barrier block 25 is arc-shaped.
[0044] Specifically, if the barrier block 25 has a right-angled cross-section, sharp edges are easily formed at the edges (even with simple polishing, there are still minor cutting edges). When fruit comes into contact with these sharp edges during inclined conveying or start-stop operations, the skin is easily damaged. However, the arc-shaped cross-section has no sharp edges, and the contact between the fruit and the barrier block 25 is a smooth arc surface contact. The contact area is more than three times larger than that of a right-angled edge, and the contact pressure is distributed throughout the arc surface, which can reduce the skin damage rate, significantly improve the commercial appearance of the fruit, and reduce unsold or discounted losses caused by skin damage. In addition, during the fruit conveying process, the arc-shaped barrier block 25 design allows excess fruit in a single compartment to fall naturally into the next compartment along the direction of the conveyor belt movement, preventing multiple fruits from accumulating in a single compartment and affecting the sorting effect.
[0045] In one embodiment, the feeding rack 21 is provided with upward-facing baffles on both sides of the conveyor belt 24.
[0046] Specifically, the baffle is made of transparent food-grade acrylic sheet, which combines high light transmittance with impact resistance. This allows operators to easily observe the fruit conveying status inside the conveyor belt 24 in real time, while also withstanding fruit collisions without easily breaking. In addition, a buffer pad is provided at the connection between the baffle and the feeding rack 21. The buffer pad is sandwiched between the baffle and the vertical rod of the feeding rack 21, which not only prevents the acrylic sheet from cracking when the bolts are tightened, but also absorbs the vibration generated by the operation of the conveyor belt 24, reducing rigid collisions between the baffle and the feeding rack 21. At the same time, the inner edge of the baffle (the side closest to the conveyor belt 24) is rounded to eliminate sharp edges and prevent the fruit from being scratched when it comes into contact with the edge.
[0047] In one specific embodiment, the tilt angle of the conveyor belt 24 is 15 degrees to 35 degrees.
[0048] Specifically, for fruits such as strawberries (each weighing 20-30g, with thin and easily damaged skin) and cherries (each weighing 5-10g, prone to rolling), the tilt angle of the conveyor belt 24 is set to 15-20 degrees. At this angle, the downward component of the fruit's own weight along the conveyor belt 24 is relatively small (approximately 25%-34% of the fruit's weight). Combined with the diamond-shaped anti-slip texture on the surface of the conveyor belt 24 and the blocking blocks 25, this prevents the fruit from sliding or colliding. At the same time, the lower tilt angle makes the conveying speed gentle (approximately 0.5-0.8m / s), reducing the contact impact force between the fruit and the blocking blocks 25 and the baffles, thus protecting the skin.
[0049] For mainstream fruits such as apples (150-200g per fruit) and pears (100-150g per fruit), the angle is set at 20-30 degrees. At this angle, the weight component of the fruit is moderate (approximately 34%-50% of its weight), which can assist the conveyor belt 24 in improving conveying efficiency (speed increased to 0.8-1.2m / s) without requiring additional power to the drive component 30. Combined with the independent discharge bin of the barrier block 25, the fruit will not slip during conveying and can quickly reach the bagging station, adapting to batch sorting needs.
[0050] For heavy fruits such as pomelos (800-1200g per fruit) and watermelons (small, 1-2kg per fruit), the angle is set to 30-35 degrees. At this angle, the weight component of the fruit is relatively large (approximately 50%-58% of its weight), which can significantly reduce the power load on the drive component 30 (driving power requirement reduced by more than 30%), avoiding motor overload; at the same time, heavy fruits have greater inertia and are less likely to slip due to the increased angle. Combined with the thickened anti-slip texture on the surface of the conveyor belt 24, stable conveying can be achieved.
[0051] In one embodiment, the drive assembly 30 includes a drive motor 31 and a power transmission component. The drive motor 31 is fixedly connected to the frame 10, and one end of the power transmission component is drivenly connected to the drive motor 31, while the other end is drivenly connected to the main feeding transmission component 22.
[0052] Specifically, a three-phase asynchronous servo motor is selected to meet the power requirements of the sorting and climbing mechanism: rated power 1.5kW, rated speed 1500r / min, and output speed reduced to 75r / min through a matching planetary reducer (reduction ratio 1:20), and torque increased to 120N・m. These parameters can meet the power requirements of 6 sets of feeding components simultaneously conveying 20 fruits (maximum load of 5kg per set). The motor also has a 0-100% stepless speed regulation function, with a speed regulation range covering 5-75r / min, to adapt to the conveying speed requirements of different fruits (soft / hard, large / small).
[0053] Within the pre-reserved installation space for the drive assembly 30 in the frame 10, a stainless steel motor mounting base is welded. The base surface has oblong mounting holes for easy fine-tuning of the motor position. Four sets of reinforcing ribs are welded to the bottom of the base and fixed to the main frame of the frame 10 to ensure no deformation when the base bears the weight of the motor. Furthermore, rubber vibration damping pads are added between the motor and the mounting base. These pads are tightly connected to the motor base and mounting base via bolts. Spring washers are installed between the bolts and the motor base to prevent loosening of the bolts due to vibration during motor operation.
[0054] The power transmission component can adopt a transmission structure of "drive sprocket + synchronous chain + driven sprocket set" to ensure efficient power transmission and synchronization of all feeding components. The drive sprocket is fixed on the output shaft of the drive motor 31 reducer; the drive sprocket and the output shaft are connected by a flat key, the keyway clearance is ≤0.05mm, and a stop washer and a round nut are installed on the outside of the sprocket to prevent the sprocket from moving axially.
[0055] The synchronization chain uses a single-row roller chain, and a plastic dust cover is installed on the outside of the chain.
[0056] For each feeding assembly 20, one driven sprocket is provided for the main feeding transmission component 22 (drive shaft). The specifications of the driven sprocket are exactly the same as those of the drive sprocket. The driven sprocket is fixed to the drive shaft of the main feeding transmission component 22 by a flat key. All driven sprockets are arranged in a straight line along the inclined direction of the frame 10. The parallelism error between the center axis of the sprocket and the center axis of the drive sprocket is ≤0.1mm / m, ensuring that there is no jamming when the synchronous chain meshes with all sprockets.
[0057] In other words, the high torque output of the three-phase asynchronous servo motor, when matched with the reducer, can easily drive multiple feeding components 20 to operate synchronously. Even if all six feeding components 20 are fully loaded with fruit, the motor speed fluctuation is ≤±1%, avoiding conveyor belt 24 jamming due to insufficient power. At the same time, the transmission efficiency of "active sprocket + synchronous chain" is much higher than that of belt drive, significantly reducing power loss and reducing energy costs in the long term. In addition, all driven sprockets are of the same specification and their parallelism is precisely controlled, ensuring that the synchronous chain drives each driven sprocket to rotate at the same speed, thereby making the conveyor belt 24 of the six feeding components 20 move at the same speed. This high synchronization avoids the fruit accumulation caused by "some components moving fast and some components moving slow" in traditional transmission methods (fast components running idle, slow components blocking material), ensuring that the fruit is transported evenly along multiple channels, laying the foundation for "orderly feeding" for subsequent sorting and inspection.
[0058] In one embodiment, both the conveyor belt 24 and the barrier block 25 are made of flexible material.
[0059] Specifically, the conveyor belt 24 is made of food-grade flexible PVC composite material. The base material is PVC resin (70%), with the addition of 15% dioctyl phthalate (plasticizer to improve flexibility), 10% calcium carbonate (reinforcing agent to balance flexibility and strength), and 5% antioxidant and anti-aging agent (to extend service life). This forms a composite structure of "soft contact and hard support"—ensuring sufficient flexibility when in contact with fruit, while also being able to withstand the tension and friction of the transmission components, thus preventing the conveyor belt 24 from stretching and deforming.
[0060] The barrier block 25 and the conveyor belt 24 are made of the same soft PVC material to ensure that they have the same flexibility. On the one hand, this avoids "hard-soft contact" caused by the barrier block 25 being harder than the conveyor belt 24 (such as the hard barrier block 25 colliding with the soft conveyor belt 24, which can easily cause local wear). On the other hand, the soft material can buffer the impact force between the fruit and the barrier block 25, and is especially suitable for fruits with fragile skin such as strawberries and peaches.
[0061] In one embodiment, sorting compatible with different fruit diameters can also be achieved in the following ways: First, design combinations of different numbers of feeding components 20 (e.g., 8 sets of feeding components 20 for small-diameter fruits and 4 sets of feeding components 20 for large-diameter fruits); Second, adopt a telescopic feeding rack structure, and change the effective conveying width of a single feeding component 20 (adjustment range 50-200mm) by adjusting the spacing of the baffles on both sides of the feeding rack 21.
[0062] This invention discloses a fruit bagging device, including the sorting and climbing mechanism described above.
[0063] Specifically, by setting up a sorting ramp mechanism and utilizing the drive component 30 to drive all the feeding components 20, synchronous movement of all the feeding components 20 can be achieved. This eliminates the need for manual feeding of each fruit individually; instead, fruits to be sorted are simply placed in batches into the parallel feeding components 20. The synchronized tilting of the components facilitates automated transport of the fruit from the sorting starting point to the subsequent inspection / grading stages. This design eliminates reliance on manual labor in the feeding process and avoids interruptions caused by fruit accumulation in a single feeding channel, significantly improving the continuity of the sorting process and laying the foundation for efficient subsequent sorting. Furthermore, the parallel arrangement of several feeding components 20 effectively expands multiple parallel feeding channels within the same time dimension. Compared to a single feeding channel, multi-channel parallel transport allows the fruit loading rate per unit time to increase proportionally with the number of feeding components 20. Simultaneously, the synchronous movement driven by the drive component 30 ensures consistent conveying speeds across channels, preventing fruit accumulation or leakage due to speed differences between channels, further guaranteeing high conveying efficiency.
