Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fruit bagging equipment, and more particularly to a turnover material receiving mechanism and fruit bagging equipment. BACKGROUND

[0002] The current mainstream fruit bagging equipment adopts a fixed receiving table design for the core bearing structure. The size parameters (especially the longitudinal span adapted to the length of the bag) of such a receiving table are fixed at the time of factory shipment, and can only match fruit bags of a specific length specification. In actual application scenarios, there are significant differences in the length of fruit bags required for different varieties of fruits (such as apples, pears, citrus fruits, etc.). Even for the same variety of fruit, due to differences in growth cycle and climate conditions in different planting areas, different length fruit bags need to be selected to adapt to the fruit development needs, which leads to obvious limitations of the bagging equipment with a fixed receiving table. When different length specifications of fruit bags need to be replaced, the receiving table needs to be disassembled, replaced or significantly modified as a whole, which not only increases the time and labor costs of equipment adjustment, but also may affect the stability of subsequent bagging operations due to precision deviations during disassembly and assembly, making it difficult to meet the diversified and flexible bagging needs of orchards.

[0003] At the same time, in the discharging link of the bagging operation process, the existing equipment still has the problem of insufficient operation convenience. Due to the structural limitations of the fixed receiving table, the internal space layout is relatively closed and cannot be adjusted. The fruit after bagging (or fruit bag semi-finished product) needs to be manually inserted into the receiving table for picking and discharging. This operation method requires the operator to frequently insert into the equipment, which may cause certain safety hazards due to collisions with the edges or internal components of the receiving table. On the other hand, the action range of manual insertion operation is limited, and the discharging efficiency is low. Especially in large-scale operation scenarios, the bagged fruits are easily accumulated, further affecting the continuous operation efficiency of the overall equipment, which is not conducive to the operator to achieve convenient and efficient standardized operation. SUMMARY

[0004] The purpose of the present application is to overcome the defects of the prior art and provide a turnover material receiving mechanism and fruit bagging equipment.

[0005] To achieve the above-mentioned purpose, the following technical solutions are adopted in the present application: In a first aspect, the present application provides a turnover material receiving mechanism, comprising: a rack, the rack is provided with a driving assembly, the driving assembly is drivingly connected with a lifting assembly, the lifting assembly is movably connected with a turnover supporting assembly, the turnover supporting assembly is further drivingly connected with a turnover power assembly, the driving assembly is used to drive the lifting assembly to move up and down, so as to control the lifting stroke of the turnover supporting assembly, and the turnover power assembly is used to drive the turnover supporting assembly to turn over.

[0006] In an embodiment, the driving assembly comprises a servo motor, a first gear, a second gear, a transmission shaft and a synchronous belt, the first gear is in transmission connection with the servo motor, the second gear is in meshing transmission with the first gear, one end of the transmission shaft is in transmission connection with the second gear, and the other end is in transmission connection with the synchronous belt, and the lifting assembly is in transmission connection with the synchronous belt.

[0007] In an embodiment, the lifting assembly comprises a lifting platform and a connecting piece, the lifting platform is in transmission connection with the synchronous belt through the connecting piece, and the turnover supporting assembly is movably connected with the lifting platform.

[0008] In an embodiment, the lifting platform is provided with a plurality of hinge pieces on the outer side, the turnover supporting assembly is in abutment with the lifting platform, and the turnover supporting assembly is connected with the hinge pieces.

[0009] In an embodiment, the lifting platform is connected with the turnover power assembly on the side away from the hinge pieces, the turnover power assembly pushes the turnover supporting assembly to make the turnover supporting assembly side turn along the hinge pieces.

[0010] In an embodiment, the turnover power assembly is located at the bottom of the lifting platform, the turnover power assembly comprises a mounting seat and a turnover cylinder, the mounting seat is connected with the lifting platform, the turnover cylinder is connected with the mounting seat, and the telescopic end of the turnover cylinder penetrates through the lifting platform and is in transmission connection with the turnover supporting assembly.

[0011] In an embodiment, the number of the turnover power assemblies is two, and the turnover power assemblies correspond to the two sides of the turnover supporting assembly.

[0012] In an embodiment, the turnover supporting assembly comprises a turnover supporting plate, the outer side of the turnover supporting plate is connected with the hinge pieces, and the inner side is in transmission connection with the turnover cylinder.

[0013] In an embodiment, the turnover supporting plate further extends upwardly with a baffle.

[0014] Compared with the prior art, the turnover material receiving mechanism has the beneficial effects that: through the transmission cooperation of the driving assembly and the lifting assembly, the turnover supporting assembly can be driven to realize up-down movement and precise control of the lifting stroke. This design enables the receiving height of the turnover supporting assembly to be flexibly adjusted according to actual bagging needs. Whether it is different lengths of fruit bags required by different varieties of fruits (such as apples, pears, citrus fruits, etc.), or the length changes of fruit bags adapted to different growth periods and different climate conditions of the same variety of fruits, can be perfectly matched by adjusting the lifting position of the turnover supporting assembly. Without disassembling, replacing or modifying the receiving structure, the driving assembly can complete the rapid adjustment, greatly reducing the time cost and labor cost of equipment adjustment, effectively avoiding the influence of disassembly precision deviation on bagging stability, enabling the bagging equipment to meet the diversified and flexible operation needs of orchards, and significantly widening the application range. In addition, through the transmission connection of the turnover power assembly and the turnover supporting assembly, the turnover supporting assembly can be directly turned over after bagging to dump the received fruits (or fruit bag semi-finished products) to the outside. This turnover unloading method changes the traditional "manual probing" operation mode. On the one hand, the operator no longer needs to stretch into the equipment interior, avoiding the safety hazards of bumping into the edge of the receiving table or the internal components, significantly improving the operation safety. On the other hand, the fruits can be directly transferred to the subsequent collection or transfer link after being dumped to the outside, with small operation amplitude and simple process, effectively improving the unloading efficiency. Especially in large-scale operation scenarios, the problem of fruit accumulation after bagging can be avoided, ensuring the continuous and stable operation of the equipment, and helping to realize convenient and efficient standardized bagging operation. In addition, the precise control of the lifting stroke by the driving assembly ensures that the turnover supporting assembly can maintain a stable receiving posture at different height positions, avoiding the influence of receiving deviation caused by height adjustment on bagging accuracy. When the turnover power assembly drives the turnover supporting assembly to turn over, the transmission stability can ensure that the fruits are not easily damaged during dumping, which is conducive to maintaining the appearance quality of the fruits. The coordinated work of the components not only solves the core defects of the existing equipment, but also further improves the overall stability and reliability of the bagging operation, providing a better structural support for the large-scale and mechanized production of fruit bagging.

This design enables the receiving height of the overturning supporting assembly to be flexibly adjusted according to the actual bagging requirements. Whether it is different lengths of fruit bags required by different varieties of fruits (such as apples, pears, citrus fruits, etc.), or the length changes of fruit bags adapted to different growth periods and different climate conditions of the same variety of fruits, can be perfectly matched by adjusting the lifting position of the overturning supporting assembly. The receiving structure does not need to be disassembled, replaced or modified. The driving assembly can complete the rapid adjustment, greatly reducing the time cost and labor cost of equipment adjustment, effectively avoiding the influence of disassembly precision deviation on the stability of bagging, enabling the bagging device to meet the diversified and flexible operation requirements of orchards, and significantly widening the application range. In addition, through the transmission connection of the overturning power assembly and the overturning supporting assembly, the overturning supporting assembly can be directly driven to overturn after bagging, and the received fruits (or fruit bag semi-finished products) are poured out. This overturning unloading mode changes the traditional "manual insertion" operation mode: on the one hand, the operator does not need to stretch into the equipment, avoiding the safety hazards of bumping with the edge of the receiving table or the internal components, significantly improving the operation safety; on the other hand, the fruits can be directly poured into the subsequent collection or transportation link after being poured out, the operation action range is small, the process is simple, and the unloading efficiency is effectively improved. Especially in large-scale operation scenarios, the problem of fruit accumulation after bagging can be avoided, the continuous and stable operation of the equipment is ensured, and convenient and efficient standardized bagging operation is achieved. In addition, the precise control of the lifting stroke of the driving assembly ensures that the overturning supporting assembly can maintain a stable receiving posture at different height positions, avoiding the influence of receiving deviation caused by height adjustment on bagging accuracy; when the overturning power assembly drives the overturning supporting assembly to overturn, the transmission stability can ensure that the fruits are not easily collided or damaged during pouring, which is conducive to maintaining the appearance quality of the fruits. The coordinated work of the components not only solves the core defects of the existing equipment, but also further improves the overall stability and reliability of the bagging operation, providing a better structural support for the large-scale and mechanized production of fruit bagging.

In addition, those skilled in the art can combine and combine different embodiments or examples described in the present application.

[0027] Referring to Figures 1 to 3 As shown, the present application discloses a specific embodiment of a turnover feeding mechanism, which comprises a rack 10, a driving assembly 20 mounted on the rack 10, a lifting assembly 30 drivingly connected with the driving assembly 20, a turnover supporting assembly 40 movably connected with the lifting assembly 30, and a turnover power assembly 50 drivingly connected with the turnover supporting assembly 40. The driving assembly 20 is used to drive the lifting assembly 30 to move up and down, so as to control the lifting stroke of the turnover supporting assembly 40. The turnover power assembly 50 is used to drive the turnover supporting assembly 40 to turn over.

[0028] Specifically, the rack 10 is used as the installation basis of the whole mechanism and is made of aluminum alloy profile by welding. Symmetrical vertical guide grooves are arranged on both sides of the rack 10, which are used to provide stable guide support for the lifting assembly 30 and ensure that there is no deviation and shaking during lifting. The bottom of the rack 10 is also provided with leveling feet, which can adjust the overall levelness according to the on-site operation environment and ensure the stability of the mechanism operation.

[0029] The driving assembly 20 can be selected as a combination structure of a servo motor 21 and a ball screw pair. The servo motor 21 is fixed to the rack 10 through a motor seat, and the output shaft thereof is connected with the ball screw through a shaft coupling. The ball screw is rotatably connected with the rack 10 through a bearing seat. The lifting assembly 30 includes a lifting plate and guide blocks. The guide blocks are fixed to both sides of the lifting plate and are slidably matched with vertical guide rail grooves of the rack 10. A nut seat adapted to the ball screw is arranged in the middle of the lifting plate, and the nut seat is threadedly connected with the ball screw. When the servo motor 21 is started, the ball screw is driven to rotate forward and reversely, and the lifting plate is driven to move up and down along the vertical guide rail groove through thread transmission, so as to realize the lifting stroke control of the turnover supporting assembly 40. The servo motor 21 is also matched with a position encoder, which can accurately feedback the position information of the lifting plate, so that the control accuracy of the lifting stroke reaches ±0.5 mm.

[0030] The turnover supporting assembly 40 includes a receiving plate and a turnover shaft. The receiving plate is provided with an arc-shaped groove on the surface to adapt to the shape of the fruit and prevent the fruit from rolling during receiving. The turnover shaft transversely penetrates the middle of the receiving plate and is rotatably connected with the shaft seats on both sides of the lifting plate through bearings. The turnover power assembly 50 is selected as a step motor and a worm gear reducer. The step motor is fixed to the side surface of the lifting plate, and the output shaft thereof is connected with the input end of the worm gear reducer. The output end of the reducer is connected with one end of the turnover shaft through a key. When the step motor is started, the turnover shaft is driven to rotate after being decelerated and increased in torque by the reducer, and then the receiving plate is driven to realize a turnover action of 0-90° around the turnover shaft. The turnover angle can be accurately controlled through the pulse number of the step motor.

[0031] Before operation, according to the height specification of the fruit to be bagged, the control system sends an instruction to the servo motor 21 to drive the lifting plate to move the receiving plate to a preset height. During bagging operation, the fruit that has completed bagging falls into the arc-shaped groove of the receiving plate to realize stable receiving. After the bagging is completed, the control system sends a turnover instruction to the step motor, the step motor drives the receiving plate to turn over by 90°, and the fruit is poured to the outside into the collecting frame, and then the receiving plate is reset to the horizontal state to enter the next receiving cycle.

[0032] That is, through the transmission cooperation of the driving assembly 20 and the lifting assembly 30, the turnover supporting assembly 40 can be driven to realize up-down movement and precise control of the lifting stroke. This design enables the receiving height of the turnover supporting assembly 40 to be flexibly adjusted according to actual bagging needs - whether it is different lengths of fruit bags required for different varieties of fruits (such as apples, pears, citrus fruits, etc.), or the length changes of fruit bags adapted to different growth periods and different climate conditions of the same variety of fruits, can all be perfectly matched by adjusting the lifting position of the turnover supporting assembly 40, without the need to disassemble, replace or modify the receiving structure. Rapid adjustment can be achieved through the driving assembly 20 alone, greatly reducing the time and labor costs of equipment adjustment, effectively avoiding the impact of disassembly precision deviation on bagging stability, enabling the bagging equipment to meet the diversified and flexible operation needs of orchards, and significantly widening the scope of application. In addition, through the transmission connection of the turnover power assembly 50 and the turnover supporting assembly 40, the turnover supporting assembly 40 can be directly driven to overturn after bagging, dumping the received fruits (or fruit bag semi-finished products) to the outside. This overturning unloading method changes the traditional "manual insertion" operation mode: on the one hand, the operator no longer needs to reach into the equipment, avoiding the safety hazards of bumping into the edge of the receiving table or the internal components, significantly improving the operation safety; on the other hand, the fruits can be directly transferred to the subsequent collection or transfer link after being dumped to the outside, with small operation amplitude and simple process, effectively improving the unloading efficiency; especially in large-scale operation scenarios, it can avoid the problem of fruit accumulation after bagging, ensuring the continuous and stable operation of the equipment, and facilitating convenient and efficient standardized bagging operation. In addition, the precise control of the lifting stroke by the driving assembly 20 ensures that the turnover supporting assembly 40 can maintain a stable receiving posture at different height positions, avoiding the impact of height adjustment on bagging accuracy; when the turnover power assembly 50 drives the turnover supporting assembly 40 to overturn, the smooth transmission ensures that the fruits are not easily damaged during dumping, which is conducive to maintaining the appearance quality of the fruits. The coordinated work of the components not only solves the core defects of existing equipment, but also further improves the overall stability and reliability of the bagging operation, providing a more optimal structural support for the large-scale and mechanized production of fruit bagging.

[0033] In an embodiment, the driving assembly 20 includes a servo motor 21, a first gear, a second gear, a transmission shaft 22, and a synchronous belt 23. The first gear is transmissionally connected to the servo motor 21, the second gear is meshingly transmissionally connected to the first gear, one end of the transmission shaft 22 is transmissionally connected to the second gear, and the other end is transmissionally connected to the synchronous belt 23. The lifting assembly 30 is transmissionally connected to the synchronous belt 23.

[0034] Specifically, the servo motor 21 is fixed to the rack 10 through an L-shaped motor support, and the motor output shaft is fixed in the circumferential direction with the first gear through a flat key. The first gear is a spur cylindrical gear with a module of 2 and a tooth number of 15, the end face of which is in contact with the shaft shoulder of the motor output shaft, and the axial position is limited by a shaft check ring. The second gear is in meshing transmission with the first gear, and is a spur cylindrical gear with a module of 2 and a tooth number of 30, and the tooth number ratio is 2:1 to achieve the effect of speed reduction and torque increase. The second gear is installed at one end of the transmission shaft 22 through a rolling bearing, the transmission shaft 22 is made of 45 steel, the axis thereof is parallel to the axis of the output shaft of the servo motor 21, and is horizontally fixed to the rack 10 through two bearing seats arranged at intervals. The synchronous belt transmission part includes a driving synchronous pulley, a driven synchronous pulley and a polyurethane synchronous belt 23. The driving synchronous pulley is fixed to the other end of the transmission shaft 22 through a key, and the driven synchronous pulley is installed on the corresponding position of the rack 10 through a bearing seat. The diameter ratio of the driving synchronous pulley to the driven synchronous pulley is 1:1 to ensure that the transmission ratio is constant. The inside of the synchronous belt 23 is provided with a tooth-shaped structure matched with the tooth groove of the pulley, and the outside is rigidly connected with the lifting plate of the lifting assembly 30 through bolts.

[0035] When it is necessary to drive the lifting assembly 30 to move, the servo motor 21 starts and drives the first gear to rotate. The first gear drives the second gear to rotate through the meshing relationship. Since the tooth number ratio is 2:1, the rotating speed of the second gear is reduced to 1 / 2 of the rotating speed of the servo motor 21, and the torque is increased by 1 times. The second gear drives the transmission shaft 22 to rotate synchronously, and the driving synchronous pulley at the end of the transmission shaft 22 rotates accordingly. The power is transmitted to the driven synchronous pulley through the polyurethane synchronous belt 23. The synchronous belt 23 is in a tensioned state during transmission, thereby driving the lifting plate rigidly connected with the synchronous belt 23 to move smoothly along the guide groove on both sides of the rack 10, and finally realizing the lifting stroke control of the turnover supporting assembly 40. The position encoder matched with the servo motor 21 collects the motor rotating angle information in real time, the actual position of the lifting plate is calculated through the control system, and the precise closed-loop control of the lifting stroke is realized.

[0036] That is, compared with the traditional ball screw transmission, the synchronous belt 23 transmission has the characteristics of no gap and buffer vibration absorption, and can effectively absorb the impact vibration in the transmission process by cooperating with the shock absorbing gasket at the bearing seat of the transmission shaft 22. At the same time, the gear meshing adopts a spur structure with a module of 2, the meshing precision is high, and the running noise can be controlled below 65 decibels, which is lower than 75 decibels of the ball screw transmission. Not only is the working environment improved, but also the influence of vibration on the stability of the turnover supporting assembly 40 in receiving fruits is reduced, and the collision damage rate of fruits caused by vibration is reduced. In addition, the tooth number ratio of 2:1 between the first gear and the second gear realizes speed reduction and torque increase, and the output torque of the driving assembly 20 is improved, which can meet the needs of simultaneously receiving multiple groups of fruits or bagging larger size fruits, and expand the application scenarios of the equipment.

[0037] In an embodiment, the lifting assembly 30 comprises a lifting platform 31 and a connecting piece, the lifting platform 31 is drivingly connected to the synchronous belt 23 through the connecting piece, and the turnover supporting assembly 40 is movably connected to the lifting platform 31.

[0038] Specifically, the left and right sides of the lifting platform 31 are symmetrically welded with guide sliding blocks, the guide sliding blocks are made of wear-resistant cast iron, the cross section of the guide sliding blocks is in a "T" shape, the guide sliding blocks are matched with the "T" shaped guide rail grooves pre-set on the two sides of the rack 10, the matching gap between the guide sliding blocks and the guide rail grooves is controlled to be between 0.1-0.2mm, and it is ensured that the lifting platform 31 does not jam and deviate when moving along the guide rail grooves. In addition, the connecting piece comprises a connecting seat, a buffer pad and locking bolts, the connecting seat is made of aluminum alloy, one side of the connecting seat is provided with an arc-shaped groove matched with the shape of the synchronous belt 23, a rubber buffer pad with a thickness of 5mm is pasted on the inner wall of the groove, and an anti-skid texture is arranged on the surface of the buffer pad; the other side of the connecting seat is rigidly connected with the lifting platform 31 through bolts. After the synchronous belt 23 passes through the arc-shaped groove of the connecting seat, the connecting seat and the synchronous belt 23 are tightly fixed through two symmetrically arranged locking bolts, and an elastic washer is sleeved on the screw end of the locking bolt to prevent the locking bolt from loosening due to long-term vibration.

[0039] When the synchronous belt 23 of the driving assembly 20 moves, the power is stably transmitted to the lifting platform 31 through the arc-shaped groove and the anti-skid buffer pad of the connecting piece, and the lifting platform 31 moves stably along the vertical direction under the cooperation of the guide sliding blocks on the two sides and the guide rail grooves of the rack 10; at the same time, the lifting platform 31 drives the turnover supporting assembly 40 to move synchronously, so as to realize the lifting stroke adjustment of the turnover supporting assembly 40.

[0040] In an embodiment, the outer side of the lifting platform 31 is provided with a plurality of hinge pieces 32, the turnover supporting assembly 40 abuts against the lifting platform 31, and the turnover supporting assembly 40 is connected to the hinge pieces 32.

[0041] Specifically, the hinge pieces 32 are heavy-duty hinges made of stainless steel, each group of hinge pieces 32 comprises a fixed leaf and a movable leaf, and the two are hingedly connected through a stainless steel pin shaft. There are two groups of hinge pieces 32, the fixed leaf is rigidly connected with the lifting platform 31 through an internal hexagonal bolt, the bolt hole is designed as a countersunk head to ensure that the fixed leaf is closely attached to the lifting platform 31; the movable leaf is arranged upward, and a threaded connection hole is reserved at the free end of the movable leaf for connection with the turnover supporting assembly 40. In addition, the bottom of the receiving plate of the turnover supporting assembly 40 is welded with a connecting lug plate corresponding to the position of the movable leaf of the hinge piece 32, and a through hole matched with the threaded connection hole of the movable leaf is formed in the connecting lug plate. The connecting lug plate and the movable leaf are tightly connected through a bolt. At the same time, the bottom area of the receiving plate is provided with a rubber abutting pad, when the turnover supporting assembly 40 is in a horizontal receiving state, the rubber abutting pad is closely abutted against the upper surface of the lifting platform 31, so as to ensure the horizontal degree and stability of the receiving plate.

[0042] That is, compared with the traditional flip shaft + bearing seat structure, the hinge 32 is used to realize the articulation of the flip support assembly 40, the number of parts is reduced, the assembly process is simplified, and the risk of jamming caused by multiple component cooperation is reduced.

[0043] In an embodiment, the lifting platform 31 is connected to the flip power assembly 50 on the side away from the hinge 32, and the flip power assembly 50 pushes the flip support assembly 40 to make the flip support assembly 40 side flip along the hinge 32.

[0044] Specifically, the flip power assembly 50 selects a servo electric push rod, the rated thrust of which is 3000N, and the stroke is 200mm. The end of the electric push rod is provided with a spherical hinge joint to adapt to multi-angle transmission. The electric push rod is fixed to the side of the lifting platform 31 away from the hinge 32 through an L-shaped mounting bracket. The bracket is fastened and connected to the lifting platform 31 through expansion bolts at the bottom, and anti-skid rubber pads are installed between the connecting surfaces to enhance stability. The axis of the electric push rod is inclined upward at an angle of 45° with the surface of the lifting platform 31, the spherical hinge joint end thereof faces the flip support assembly 40, and the distance between the spherical hinge joint end and the side wall of the lifting platform 31 is kept at 50mm to avoid interference with other components during movement. In addition, a U-shaped connecting seat is welded on the bottom of the receiving plate of the flip support assembly 40 away from the hinge 32, the opening of the connecting seat faces downward, and the inside is hinged to the spherical hinge joint of the electric push rod through a pin shaft, and the pin shaft is axially limited through a split pin at both ends. At the same time, an ear plate is welded on the bottom of the receiving plate close to the hinge 32, and the ear plate is fastened and connected to the movable leaf through a bolt, forming a lever structure with the hinge 32 pin shaft as the rotation center, and the thrust point of the electric push rod is located at the free end of the lever (away from the rotation center side); when the receiving plate is in a horizontal receiving state, the electric push rod is in a retracted position to the shortest stroke.

[0045] After the bagging is completed, the control system sends an extension command to the servo electric push rod, and the push rod of the electric push rod extends at a rated speed to exert an inclined upward thrust on the bottom of the receiving plate through the U-shaped connecting seat. Due to the articulation of the receiving plate with the lifting platform 31 through the hinge 32, the receiving plate is side flipped away from the electric push rod (i.e. the side where the hinge 32 is located) around the pin shaft of the hinge 32 under the action of the thrust. During the flipping process, the spherical hinge joint of the electric push rod can adaptively adjust the angle to avoid generating additional torque. When the flipping angle reaches the preset angle, the electric push rod stops extending, the receiving plate remains in an inclined state, and the fruits are poured out to the collecting frame under the action of gravity; after the discharging is completed, the electric push rod receives a retraction command, the push rod is retracted, and the receiving plate is reset to a horizontal state around the pin shaft of the hinge 32. At this time, the rubber abutting pad at the bottom of the receiving plate is again closely abutted with the surface of the lifting platform 31 to restore the stable receiving posture.

[0046] In an embodiment, the overturning power assembly 50 is located at the bottom of the lifting platform 31, and the overturning power assembly 50 comprises a mounting seat 51 connected to the lifting platform 31 and an overturning cylinder 52 connected to the mounting seat 51, and the telescopic end of the overturning cylinder 52 penetrates through the lifting platform 31 and is drivingly connected to the overturning support assembly 40.

[0047] Specifically, the mounting seat 51 is fastened to the bottom of the lifting platform 31 by means of an internal hexagonal bolt. The overturning cylinder 52 is a single-rod double-acting cylinder. The overturning cylinder 52 is connected to the mounting seat 51 through mounting ear plates on both sides. The lifting platform 31 is provided with a guide hole at a position corresponding to the telescopic end of the overturning cylinder 52. The telescopic end (piston rod) of the overturning cylinder 52 is provided with a floating joint, which is hinged to a driving joint at the bottom of the receiving plate of the overturning support assembly 40 after penetrating through the guide hole of the lifting platform 31. The driving joint is fixed to the bottom of the receiving plate away from the hinge 32 by welding, forming a driving structure with the hinge 32 as the rotation center.

[0048] When overturning is needed, the control system controls the air inlet of the rodless cavity of the overturning cylinder 52, the piston rod extends out, pushes the driving joint upward through the floating joint, and the receiving plate is overturned to the outside (the side where the hinge 32 is located) of the hinge 32 under the action of the pushing force; when the overturning angle reaches the set value, the overturning cylinder 52 feeds back the position signal through the magnetic switch, stops extending out, and the fruits are poured under the action of gravity; after the discharging is completed, the rod cavity of the overturning cylinder 52 is filled with air, the piston rod retracts, and the receiving plate is reset to the horizontal state, and the rubber abutting pad is abutted with the lifting platform 31 again, completing a overturning cycle.

[0049] That is, the overturning power assembly 50 is moved to the bottom of the lifting platform 31, which completely releases the space above and on the side of the lifting platform 31, so that the receiving area of the overturning support assembly 40 is not blocked by any power component, which not only facilitates the observation of the receiving state of the fruits, but also provides more sufficient layout space for the feeding mechanism, positioning mechanism, etc. of the bagging equipment. At the same time, the openness of the upper space reduces the risk of interference of the fruits falling into the receiving plate after being bagged, and improves the discharging accuracy.

[0050] In an embodiment, the overturning support assembly 40 comprises an overturning support plate 41, the outer side of which is connected to the hinge 32, and the inner side is drivingly connected to the overturning cylinder 52.

[0051] Specifically, the turnover support plate 41 is stamped and formed by a food-grade 304 stainless steel plate, and the plate surface is uniformly distributed with air holes to reduce weight and avoid adsorption problems caused by local air pressure difference when the fruits are received. The outer side edge of the turnover support plate 41 (along the installation direction of the hinge part 32) is rounded to prevent the operator from being injured by knocking. An L-shaped connecting piece (including a horizontal section and a vertical section) is welded to the outer side of the turnover support plate 41, and the connecting piece is made of the same material as the support plate. The horizontal section is welded to the upper surface of the support plate, and the vertical section is provided with a through hole matched with the threaded hole of the movable page of the hinge part 32. The movable page of the hinge part 32 is fastened to the vertical section of the connecting piece by an inner hexagonal bolt, and a spring washer is added after the bolt is tightened to prevent loosening. A transmission seat is welded to the inner side of the turnover support plate 41, and the transmission seat is connected to the extension end (piston rod) of the turnover cylinder 52.

[0052] When the fruits are received horizontally, the lower surface of the turnover support plate 41 abuts against the surface of the lifting platform 31 through three evenly distributed silica gel support blocks, ensuring that the horizontal degree error of the support plate is ≤0.3 mm / m. After the bagging is completed, the piston rod of the turnover cylinder 52 is extended, driving the transmission seat to move upward, and the turnover support plate 41 is turned outward with the pin shaft of the hinge part 32 as the center of rotation, and the silica gel support blocks gradually separate from the lifting platform 31; when the turning angle reaches the set value (for example: 75 degrees or 90 degrees), the turnover cylinder 52 stops moving, and the fruits slide along the inclined surface of the support plate to the collecting device; after the fruits are unloaded, the piston rod of the turnover cylinder 52 is retracted, pulling the support plate to return to the horizontal state, and the silica gel support blocks abut against the lifting platform 31 again, completing the cycle.

[0053] In an embodiment, the turnover support plate 41 also extends upwardly with a baffle.

[0054] Specifically, the baffle and the turnover support plate 41 are integrally stamped and formed. According to the direction of the turnover unloading of the turnover support plate 41, the “unloading side” is the side of the support plate when the fruits are poured (i.e. close to the outer side edge of the hinge part 32), and the other three sides extend upwardly to form baffles. The height of the baffle is uniformly set to 80 mm, and the top edge is treated with an inner hem, with a hem radius of 5 mm, which not only enhances the structural strength of the baffle, but also avoids scratching the fruits or the operator by sharp edges.

[0055] In an embodiment, the number of the turnover power assemblies 50 is two groups, and corresponds to the two sides of the turnover support assembly 40.

[0056] Specifically, the two groups of air cylinders are driven simultaneously, so that the two sides of the turnover support plate 41 are uniformly stressed, and the left-right deviation amount during turnover is controlled within 0.5mm. In addition, synchronous action avoids the distortion of the turnover support plate 41 caused by unilateral stress. In addition, the total thrust of the two groups of air cylinders is 2 times that of a single group, which can easily drive a larger size or heavier load turnover support plate 41, and the adaptation range is expanded from single fruit receiving to multi-fruit batch receiving. At the same time, the dual power source design forms a redundant backup, so that even if one of the air cylinders fails, the other group can still maintain the basic turnover function, and the fault tolerance of the equipment is improved.

[0057] The application discloses a fruit bagging equipment, which comprises a turnover receiving mechanism as described above.

[0058] Specifically, by setting the turnover receiving mechanism and utilizing the transmission cooperation of the driving assembly 20 and the lifting assembly 30, the turnover supporting assembly 40 can be driven to realize up-down movement and precise control of the lifting stroke. This design enables the receiving height of the turnover supporting assembly 40 to be flexibly adjusted according to actual bagging needs, whether it is different lengths of fruit bags required by different varieties of fruits (such as apples, pears, citrus, etc.), or the length changes of fruit bags adapted to different growth periods and different climate conditions of the same variety of fruits, which can be perfectly matched by adjusting the lifting position of the turnover supporting assembly 40, without the need to disassemble, replace or modify the receiving structure. Only by the driving assembly 20 can rapid adjustment be achieved, greatly reducing the time cost and labor cost of equipment adjustment, effectively avoiding the influence of disassembly precision deviation on bagging stability, enabling the bagging equipment to meet the diversified and flexible operation needs of orchards, and significantly widening the application scope. In addition, through the transmission connection of the turnover power assembly 50 and the turnover supporting assembly 40, the turnover supporting assembly 40 can be directly turned over after bagging to dump the received fruits (or fruit bag semi-finished products) to the outside. This turnover unloading method changes the traditional "manual probing" operation mode: on the one hand, the operator no longer needs to stretch into the equipment interior, avoiding the safety hazards of bumping into the edge of the receiving table or the internal components, significantly improving the operation safety; on the other hand, the fruits can be directly transferred to the subsequent collection or transfer link after being dumped to the outside, with small operation amplitude and simple process, effectively improving the unloading efficiency; especially in large-scale operation scenarios, the problem of fruit accumulation after bagging can be avoided, ensuring the continuous and stable operation of the equipment, and facilitating the realization of convenient and efficient standardized bagging operation. In addition, the precise control of the lifting stroke by the driving assembly 20 ensures that the turnover supporting assembly 40 can maintain a stable receiving posture at different height positions, avoiding the influence of receiving deviation caused by height adjustment on bagging precision; when the turnover supporting assembly 40 is turned over by the turnover power assembly 50, the transmission stability can ensure that the fruits are not easily damaged during dumping, which is conducive to maintaining the appearance quality of the fruits. The coordinated work of the components not only solves the core defects of existing equipment, but also further improves the overall stability and reliability of the bagging operation, providing a better structural support for the large-scale and mechanized production of fruit bagging.

[0059] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
