Description

Technical Field

[0001] The present invention relates to the technical field of wolfberry processing and conveying equipment, and more specifically, to an intelligent wolfberry conveying and feeding system with low temperature and freshness preservation throughout the entire process. Background Art

[0002] At present, in the process of transporting wolfberry in the processing production line, the feeding device is mostly simple in structure, which easily causes the wolfberry to become corrupt, oxidized, and lose nutrients during transportation, thus greatly affecting the quality of wolfberry processing. In addition, during the transportation and loading process, if the wolfberry needs to be screened, cleaned, and other additional processes due to corruption and deterioration, the processing steps and time costs will be increased, and the overall processing efficiency will be reduced. However, when transporting wolfberry, it is impossible to ensure that the wolfberry is always in a low-temperature state, and the spoilage time of the wolfberry is accelerated. Refrigerated transportation cannot accurately control the temperature in the transportation channel, and a single cooling transportation method is difficult to cope with the oxidation phenomenon that occurs in the wolfberry during transportation, which easily causes the wolfberry to oxidize and deteriorate. Therefore, it is necessary to provide a wolfberry intelligent low-temperature fresh-locking transportation and loading system to solve the problems raised in the above background technology. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent wolfberry freshness-locking and low-temperature conveying and feeding system, comprising:

[0004] The conveying platform is set at the output port of the wolfberry refrigeration compartment;

[0005] A lifting conveying mechanism is arranged on the output side of the conveying platform;

[0006] The pushing mechanism is fixed on the upper part of the lifting and conveying mechanism;

[0007] There are multiple pallets distributed on the conveying platform and the lifting conveying mechanism;

[0008] The conveying line is arranged on the side of the lifting conveying mechanism away from the conveying platform and corresponds to the pushing mechanism;

[0009] The transfer box is fixed at the input end of the conveying line and corresponds to the pushing mechanism;

[0010] The protective shell is fixed on the conveying line and is located on the side of the transfer box;

[0011] The gas injection device is fixed inside the protective shell and located above the conveying line;

[0012] The cooling device is linearly distributed with a plurality of cooling devices, which are rotatably arranged at the bottom of the gas injection device.

[0013] Furthermore, as a preference, the lifting and conveying mechanism includes:

[0014] The fixed frame is set between the conveying platform and the conveying line, and is equipped with a cooling air mechanism inside;

[0015] The transmission components are symmetrically distributed with two groups and fixed inside the fixed frame;

[0016] A plurality of lifting platforms are provided in a circular distribution and fixed between the two sets of transmission components, and the lifting platforms carry the trays;

[0017] The support platforms are symmetrically arranged in two groups, with multiple support platforms distributed linearly in each group, and are fixed between the transmission assembly and the inner wall of the fixed frame;

[0018] The sorting robot arm is fixed on the support table;

[0019] The sealing surfaces are fixed on both sides of the fixed frame adjacent to the conveying platform and the conveying line. In other words, the wolfberry refrigeration compartment transports the harvested and refrigerated wolfberries to the pallets on the conveying platform. Under the action of the conveying platform, the pallets are pushed onto the lifting platform between the transmission components, and then moved upward under the drive of the transmission components. During the upward movement of the lifting platform, the conveying platform sequentially transports the pallets to the remaining lifting platforms, that is, the transmission components are in an intermittent operation state. When the transmission components stop, the sorting robotic arms on the support platforms on both sides sort the wolfberries in the pallets and remove the miscellaneous fruits. When the lifting platform drives the pallets to the highest point of the transmission component, the pallets are pushed to the transfer box on the conveying line by the pushing mechanism for subsequent transportation. Under the action of the cold air mechanism inside the fixed frame, the interior of the lifting and conveying mechanism is kept at a low temperature, effectively locking in the freshness of the wolfberries and reducing the loss of wolfberries during transportation.

[0020] Furthermore, as a preference, the pushing mechanism is fixed to the upper portion of the sealing surface near the conveying platform, and the lower portion of the sealing surface near the conveying platform is provided with an opening corresponding to the pallets on the conveying platform, while the upper portion of the sealing surface near the conveying line is provided with an opening corresponding to the transfer box. The sealing surfaces cooperate to seal the fixed frame, maintaining the internal temperature of the lifting and conveying mechanism while reducing the leakage of cold air and the energy consumption of the cooling mechanism. The openings on both sides of the sealing surface assist in the transportation of pallets into the lifting and conveying mechanism and the transport of pallets to the outside of the lifting and conveying mechanism.

[0021] Furthermore, as a preference, the pushing mechanism includes:

[0022] The fixed rail passes through the sealing surfaces on both sides and is fixed inside the fixed frame;

[0023] The hydraulic cylinder is located outside the sealing surface, fixed to the bottom of the fixed track, and is located on the same side of the lifting and conveying mechanism as the conveying platform;

[0024] A sliding wheel assembly is slidingly arranged inside the fixed track;

[0025] The push panel is positioned on the inner side of the sealing surface, with its top fixedly connected to the bottom of the sliding wheel assembly and its side fixedly connected to the extension shaft of the hydraulic cylinder. The side opposite the extension shaft corresponds to the pallet on the lifting platform at the top of the transmission assembly. In other words, when the lifting platform drives the pallet to the highest point of the transmission assembly, the transmission assembly stops rotating. While receiving the pallet from the conveyor platform, the hydraulic cylinder drives the push panel via the extension shaft toward the conveyor line. Simultaneously, the sliding wheel assembly follows the push panel within the fixed track, assisting the push panel's movement while limiting its direction of movement. Consequently, the push panel pushes the pallet away from the lifting platform and enters the transfer box through the upper opening of the sealing surface.

[0026] Furthermore, preferably, the top of the transfer box is provided with two scanning panels that can be opened and closed, and a push-out mechanism is provided inside the transfer box. When the tray enters the transfer box under the action of the push-out mechanism, the conveying line is in a stationary state, and the scanning panel on the top of the transfer box scans and inspects the wolfberries inside the tray. After ensuring that the wolfberries in the tray are intact, the conveying line starts, driving the tray into the protective shell for transportation. If there are defective wolfberries in the tray, the tray is pushed out from the side of the transfer box away from the protective shell by the push-out mechanism inside the transfer box, collected and re-sorted, and the transfer box then waits for the arrival of the next tray and repeats the inspection process.

[0027] Furthermore, preferably, the output end of the protective housing and the end adjacent to the transfer box are each provided with a sealing curtain. The curtain effectively maintains the temperature inside the protective housing at a low enough temperature to preserve the freshness of the goji berries. It also blocks the flow of air between the protective housing and the outside, maintaining a sufficient level of carbon dioxide inside the protective housing and reducing the risk of oxidation of the goji berries during transportation.

[0028] Furthermore, preferably, the gas injection device includes:

[0029] A plurality of gas injection pipelines are linearly distributed and fixed in a protective housing, located at the upper portion of the conveying line, and one end of the gas injection pipeline is connected to an external air pump;

[0030] A connecting rod is fixed on the top of the gas injection pipeline and connects multiple gas injection pipelines;

[0031] Multiple induction nozzle assemblies are distributed linearly along the gas injection pipeline and fixed to the bottom of the pipeline. In other words, an external air pump delivers carbon dioxide gas to each gas injection pipeline, and then through the induction nozzle assembly into the protective shell, creating a low-oxygen environment inside the protective shell. Simultaneously, the cooling device lowers the temperature, thereby inhibiting the respiration of the wolfberries, reducing nutrient consumption, and delaying microbial growth, thereby achieving the purpose of locking in the freshness of the wolfberries during transportation.

[0032] Furthermore, preferably, the induction nozzle assembly includes:

[0033] The nozzle body is fixed at the bottom of the gas injection pipeline;

[0034] The induction ring is fixed on the water outlet of the nozzle body;

[0035] A plurality of rotating mechanisms are provided in an annular distribution and fixed on the side of the nozzle body;

[0036] The regulating blocks are provided in a ring-shaped arrangement and are fixedly connected to the rotating mechanism. The regulating blocks form a complete circular surface. That is, under the action of the induction ring, when the cooling device is located below the induction nozzle assembly, the rotating mechanism drives the regulating blocks to rotate, increasing the spacing between the regulating blocks, increasing the delivery of carbon dioxide gas, and allowing the carbon dioxide gas to be cooled by the cooling device and then delivered to various locations inside the protective housing, thereby inhibiting the oxidation of the wolfberries while cooling them. Conversely, when the cooling device is not below the induction nozzle assembly, the induction ring does not sense the cooling device. At this time, the rotating mechanism drives the regulating blocks to rotate, reducing the spacing between the regulating blocks, reducing the delivery of carbon dioxide gas, and allowing the carbon dioxide gas to slowly be delivered to the surface of the wolfberries on the tray below, effectively preventing the wolfberries from oxidizing during the delivery process.

[0037] Furthermore, preferably, the cooling device includes:

[0038] A connecting shaft is rotatably disposed at the bottom of the connecting rod and is located between the gas injection pipes;

[0039] There are two regulating frames symmetrically distributed, with the central connection fixed at the bottom of the connecting shaft;

[0040] Multiple cooling plates are arranged in a linear arrangement, rotatably mounted on a control frame, and rotate synchronously. Driven by the connecting shaft, the control frame and cooling plates rotate beneath the gas injection device. When a cooling plate is positioned beneath the induction nozzle assembly, the corresponding induction nozzle assembly opens the adjustment block, widening the gap between the adjustment blocks and increasing the delivery of carbon dioxide gas. After being cooled by the cooling plates, the carbon dioxide gas is delivered to the protective housing. The cooling plates can be rotated to adjust the delivery direction of the carbon dioxide gas after passing through them, dispersing the cooled carbon dioxide gas into the interior of the protective housing. This maintains both a low-temperature and a low-oxygen environment, effectively locking in the freshness of the goji berries.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] In the present invention, the wolfberries in the refrigerated compartment are transported to a pallet and then to a lifting and conveying mechanism through the provision of a conveying platform; the wolfberries are transported at a low temperature through the provision of the lifting and conveying mechanism, and during the transportation process, the wolfberries are sorted and bad ones are removed; the sorted wolfberries are transported at a low temperature and protected from oxidation through the provision of a conveying assembly line, effectively ensuring that the wolfberries maintain good quality when they are transported to the processing equipment.

[0051] See also Figures 1 to 7 In an embodiment of the present invention, an intelligent low-temperature fresh-keeping wolfberry conveying and feeding system comprises:

[0052] The conveying platform 1 is arranged at the output port of the wolfberry refrigeration compartment;

[0053] The lifting conveying mechanism 2 is arranged on the output side of the conveying platform 1;

[0054] The pushing mechanism 3 is fixed on the upper part of the lifting and conveying mechanism 2;

[0055] There are multiple trays 4 distributed on the conveying platform 1 and the lifting conveying mechanism 2;

[0056] The conveying line 5 is arranged on the side of the lifting conveying mechanism 2 away from the conveying platform 1 and corresponds to the pushing mechanism 3;

[0057] The transfer box 6 is fixed at the input end of the conveying line 5 and corresponds to the pushing mechanism 3;

[0058] The protective shell 7 is fixed on the conveying line 5 and is located on the side of the transfer box 6;

[0059] The gas injection device 8 is fixed inside the protective shell 7 and is located above the conveying line 5;

[0060] The cooling devices 9 are provided in a plurality and are distributed in a straight line and are rotatably arranged at the bottom of the gas injection device 8 .

[0061] In this embodiment, the lifting and conveying mechanism 2 includes:

[0062] The fixed frame 21 is arranged between the conveying platform 1 and the conveying line 5, and is provided with a cooling air mechanism inside;

[0063] The transmission components 22 are symmetrically distributed in two groups and fixed inside the fixed frame 21;

[0064] A plurality of lifting platforms 23 are provided in an annular distribution and are fixed between the two sets of transmission components 22 , and the lifting platforms 23 carry the tray 4 ;

[0065] The support platforms 24 are symmetrically arranged in two groups, each group having a plurality of support platforms distributed linearly, and are fixed between the transmission assembly 22 and the inner wall of the fixed frame 21;

[0066] The sorting robot arm 25 is fixed on the support platform 24;

[0067] Sealing surfaces 26 are fixed to both sides of the fixed frame 21 adjacent to the conveying platform 1 and the conveying line 5. Specifically, the wolfberry refrigeration compartment transports the harvested and refrigerated wolfberries to the trays 4 on the conveying platform 1. Under the action of the conveying platform 1, the trays 4 are pushed onto the lifting platforms 23 between the transmission assemblies 22. Driven by the transmission assemblies 22, the trays 4 are then moved upward. During the upward movement of the lifting platforms 23, the conveying platform 1 sequentially transports the trays 4 to the remaining lifting platforms 23, meaning that the transmission assemblies 22 are in intermittent operation. When the transmission assemblies 22 stop, the sorting robotic arms 25 on the support platforms 24 on both sides sort the wolfberries in the trays 4 and remove any unwanted fruit. When the lifting platforms 23 drive the trays 4 to the highest point of the transmission assembly 22, the trays 4 are pushed by the pushing mechanism 3 to the transfer box 6 on the conveying line 5 for subsequent transport. Furthermore, the cooling air mechanism within the fixed frame 21 maintains a low temperature inside the lifting and conveying mechanism 2, effectively locking in the wolfberries' freshness and reducing losses during transport.

[0068] In this embodiment, the pushing mechanism 3 is fixed to the upper portion of the sealing surface 26 near the conveying platform 1. The lower portion of the sealing surface 26 near the conveying platform 1 is provided with an opening corresponding to the tray 4 on the conveying platform 1. The upper portion of the sealing surface 26 near the conveying line 5 is provided with an opening corresponding to the transfer box 6. The sealing surface 26 cooperates with the fixed frame 21 to seal, maintaining the internal temperature of the lifting and conveying mechanism 2 while reducing the leakage of cold air and lowering the energy consumption of the cooling mechanism. Furthermore, the provision of openings on the sealing surfaces 26 on both sides assists in the transportation of the tray 4 into the lifting and conveying mechanism 2 and the output of the tray 4 to the outside of the lifting and conveying mechanism 2.

[0069] In this embodiment, the pushing mechanism 3 includes:

[0070] The fixed rail 31 passes through the sealing surfaces 26 on both sides and is fixed inside the fixed frame 21;

[0071] The hydraulic cylinder 32 is located outside the sealing surface 26, fixed to the bottom of the fixed rail 31, and is located on the same side of the lifting and conveying mechanism 2 as the conveying platform 1;

[0072] The sliding wheel group 33 is slidably arranged inside the fixed track 31;

[0073] The push panel 34 is disposed on the inner side of the sealing surface 26. Its top is fixedly connected to the bottom of the sliding wheel assembly 33, and its side is fixedly connected to the extended shaft of the hydraulic cylinder 32. The side opposite the extended shaft corresponds to the pallet 4 on the lifting platform 23 at the top of the transmission assembly 22. In other words, when the lifting platform 23 drives the pallet 4 to move to the highest point of the transmission assembly 22, the transmission assembly 22 stops rotating. While receiving the pallet 4 delivered from the conveying platform 1, the hydraulic cylinder 32 drives the push panel 34 via the extended shaft toward the conveying line 5. At the same time, the sliding wheel assembly 33 follows the push panel 34 in the fixed track 31, assisting the movement of the push panel 34 while limiting its movement direction. Consequently, under the push of the push panel 34, the pallet 4 leaves the lifting platform 23 and enters the transfer box 6 through the upper opening of the sealing surface 26.

[0074] In this embodiment, the top of the transfer box 6 is provided with two scanning panels 61 that can be opened and closed, and a pushing mechanism is provided inside the transfer box 6. When the tray 4 enters the transfer box 6 under the action of the pushing mechanism 3, the conveying line 5 is in a stationary state. The scanning panel 61 on the top of the transfer box 6 scans and detects the wolfberries inside the tray 4. After ensuring that the wolfberries in the tray 4 are intact, the conveying line 5 is started, driving the tray 4 into the protective shell 7 for transportation. If there are defective wolfberries in the tray 4, the tray 4 is pushed out from the side of the transfer box 6 away from the protective shell 7 by the pushing mechanism inside the transfer box 6. After collection, it is re-sorted. At this time, the transfer box 6 waits for the arrival of the next tray 4 and repeats the inspection work.

[0075] In this embodiment, a sealing curtain 71 is provided at the output end of the protective housing 7 and at the end adjacent to the transfer box 6. The sealing curtain 71 effectively maintains the temperature inside the protective housing 7 at a low enough temperature to preserve the freshness of the wolfberries. It also blocks the flow of air between the protective housing 7 and the outside air, maintaining a sufficient amount of carbon dioxide inside the protective housing 7 and reducing the risk of oxidation of the wolfberries during transportation.

[0076] In this embodiment, the gas injection device 8 includes:

[0077] A plurality of gas injection pipes 81 are provided in a straight line and fixed in the protective housing 7, located at the upper part of the conveying line 5, and one end of the gas injection pipe 81 is connected to an external air pump;

[0078] A connecting rod 82 is fixed to the top of the gas injection pipeline 81 and connects multiple gas injection pipelines 81;

[0079] Multiple induction nozzle assemblies 83 are linearly distributed along the gas injection pipeline 81 and fixed to the bottom of the gas injection pipeline 81. In other words, under the action of an external air pump, carbon dioxide gas is delivered to each gas injection pipeline 81 and then transported into the protective shell 7 through the induction nozzle assemblies 83, creating a low-oxygen environment inside the protective shell 7. Simultaneously, the cooling device 9 cools the inside of the protective shell 7, thereby inhibiting the respiration of the wolfberries, reducing the consumption of nutrients, and delaying the growth of microorganisms, thereby achieving the purpose of locking in the freshness of the wolfberries during transportation.

[0080] In this embodiment, the induction nozzle assembly 83 includes:

[0081] The nozzle body 831 is fixed to the bottom of the gas injection pipe 81;

[0082] The induction ring 832 is fixed on the water outlet of the nozzle body 831;

[0083] A plurality of rotating mechanisms 833 are provided in an annular arrangement and fixed to the side of the nozzle body 831;

[0084] The regulating blocks 834 are provided in a circular arrangement in plurality, are arranged in the nozzle body 831, and are fixedly connected to the rotating mechanism 833, and the plurality of regulating blocks 834 form a complete circular surface. That is, under the action of the induction ring 832, when the cooling device 9 is located below the induction nozzle assembly 83, the rotating mechanism 833 drives the regulating blocks 834 to rotate, thereby increasing the spacing between the regulating blocks 834, increasing the delivery of carbon dioxide gas, and allowing the carbon dioxide gas to be cooled by the cooling device 9 and then delivered to various locations inside the protective housing 7, thereby suppressing the oxidation of the wolfberries while cooling them. Conversely, when the cooling device 9 is not below the induction nozzle assembly 83, the induction ring 832 does not sense the cooling device 9, and at this time the rotating mechanism 833 drives the regulating blocks 834 to rotate, thereby decreasing the spacing between the regulating blocks 834, reducing the delivery of carbon dioxide gas, and allowing the carbon dioxide gas to be slowly delivered to the surface of the wolfberries on the tray 4 below, effectively preventing the wolfberries from oxidizing during delivery.

[0085] In this embodiment, the cooling device 9 includes:

[0086] The connecting shaft 91 is rotatably disposed at the bottom of the connecting rod 82 and is located between the gas injection pipes 81;

[0087] There are two regulating frames 92 symmetrically distributed, with the central connection fixed to the bottom of the connecting shaft 91;

[0088] There are multiple cooling plates 93 distributed in a straight line, which are rotatably mounted on the control frame 92, and the multiple cooling plates 93 rotate synchronously. That is, driven by the connecting shaft 91, the control frame 92 and the cooling plates 93 rotate below the gas injection device 8. When the cooling plate 93 is below the induction nozzle assembly 83, the corresponding induction nozzle assembly 83 opens the adjustment block 834, increasing the spacing between the adjustment blocks 834 and increasing the delivery of carbon dioxide gas. After being cooled by the cooling plate 93, the carbon dioxide gas is delivered to the protective housing 7. The direction of delivery of the carbon dioxide gas after passing through the cooling plate 93 can be adjusted by rotating the cooling plate 93, so that the cooled carbon dioxide gas is dispersed into the interior of the protective housing 7, maintaining a low-temperature environment while maintaining a low-oxygen environment, effectively locking in the freshness of the wolfberries.

[0089] During the specific implementation, the picked wolfberries are first placed in the wolfberry cold storage compartment and transported to the processing factory. Then, the refrigerated wolfberries are uniformly transported to the tray 4 on the conveying platform 1 in sequence. Under the action of the conveying platform 1, the tray 4 is pushed to the lifting platform 23 between the transmission components 22. The wolfberries are transported at a low temperature by the lifting conveying mechanism 2. Under the intermittent operation of the transmission component 22, the sorting mechanical arms 25 on the support platforms 24 on both sides sort the wolfberries in the tray 4 and remove the miscellaneous fruits. When the lifting platform 23 drives the tray 4 to move to the transmission component 2 2, the tray 4 is pushed into the transfer box 6 on the conveying line 5 by the pushing mechanism 3, and the wolfberries inside the tray 4 are scanned and detected by the scanning panel 61 on the top of the transfer box 6. After ensuring that the wolfberries in the tray 4 are intact, the conveying line 5 is started, and the tray 4 is driven into the protective shell 7 for conveying. If there are defective wolfberries in the tray 4, the tray 4 is pushed out from the side of the transfer box 6 away from the protective shell 7 by the pushing mechanism inside the transfer box 6. After collection, it is re-sorted. At this time, the transfer box 6 waits for the next tray When the tray 4 arrives, the detection work is repeated. When the tray 4 enters the protective shell 7, the gas injection device 8, under the action of the external air pump, transports carbon dioxide gas to each gas injection pipe 81, and then transports it into the protective shell 7 through the induction nozzle assembly 83, so that the protective shell 7 is in a low-oxygen environment. At the same time, the connecting shaft 91 in the cooling device 9 drives the control frame 92 and the refrigeration plate 93 to rotate. When the refrigeration plate 93 is below the induction nozzle assembly 83, the corresponding induction nozzle assembly 83 opens the adjustment block 834, so that the interval between the adjustment blocks 834 becomes larger, thereby increasing the transportation of carbon dioxide gas. The transportation rate of the other induction nozzle assemblies 83 remains unchanged. After the carbon dioxide gas is cooled by the refrigeration plate 93, it is transported into the protective shell 7. The transportation direction of the carbon dioxide gas after passing through the refrigeration plate 93 can be adjusted by rotating the refrigeration plate 93, so that the cooled carbon dioxide gas is dispersed into the interior of the protective shell 7, maintaining a low temperature environment while maintaining a low-oxygen environment, effectively locking the freshness of the wolfberry, until the tray 4 leaves the protective shell 7 under the drive of the conveying line 5 and enters the processing mechanism.
