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 locking throughout the entire process. Background Art

[0002] At present, in the process of transporting wolfberries in the processing production line, most of the feeding devices have a simple structure, which can easily cause the wolfberries 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 wolfberries need 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 wolfberries, it is impossible to ensure that the wolfberries are always in a low-temperature state, and the spoilage time of the wolfberries is accelerated. Refrigerated transportation cannot accurately control the temperature in the transportation channel, and a single cooling transportation is difficult to cope with the oxidation phenomenon of wolfberries during transportation, which can easily cause the wolfberries to oxidize and deteriorate. Therefore, it is necessary to provide a wolfberry intelligent low-temperature fresh-locking transportation and loading system throughout the process to solve the problems raised in the above background technology. Summary of the invention

[0003] To achieve the above purpose, the present invention provides the following technical solution: an intelligent wolfberry whole-process low-temperature fresh-keeping conveying and feeding system, comprising:

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

[0005] A lifting and 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 and conveying mechanism;

[0008] The conveying assembly 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] A gas injection device is fixed inside the protective housing and is located above the conveying line;

[0012] A plurality of cooling devices are linearly distributed and rotatably arranged at the bottom of the gas injection device.

[0013] Further, as a preference, the lifting and conveying mechanism comprises:

[0014] The fixed frame is arranged between the conveying platform and the conveying assembly line, and a cooling air mechanism is provided inside;

[0015] The transmission components are symmetrically arranged in 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 platform is symmetrically arranged in two groups, each group is linearly arranged with a plurality of support platforms, and is 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 surface is fixed on both sides of the fixed frame adjacent to the conveying platform and the conveying line. That is to say, the wolfberry refrigerated compartment conveys the refrigerated wolfberries after picking to the pallets on the conveying platform, and under the action of the conveying platform, the pallets are pushed to the lifting platform between the transmission components, and then moved upward under the drive of the transmission component, and in the process of the lifting platform moving up, the conveying platform sequentially conveys the pallets to the remaining lifting platforms, that is, the transmission component is in an intermittent operation state. When the transmission component stops, the sorting mechanical 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 pallet to move to the highest point of the transmission component, the pallet is pushed to the transfer box on the conveying line through the pushing mechanism for subsequent conveying work, and under the action of the cold air mechanism inside the fixed frame, the inside of the lifting and conveying mechanism is kept at a low temperature, which effectively locks the freshness of the wolfberries and reduces the loss of wolfberries during the transportation process.

[0020] Furthermore, as a preference, the pushing mechanism is fixed to the upper part of the sealing surface close to the conveying platform, and the lower part of the sealing surface close to the conveying platform is provided with an opening corresponding to the pallet on the conveying platform, and the upper part of the sealing surface close to the conveying line is provided with an opening corresponding to the transfer box. With the cooperation of the sealing surface, the fixed frame is closed, and while maintaining the internal temperature of the lifting and conveying mechanism, the cold air leakage is reduced, and the energy consumption of the cold air mechanism is reduced. The openings on the sealing surfaces on both sides assist the pallet to be transported into the lifting and conveying mechanism, and output to the outside of the lifting and conveying mechanism.

[0021] Further, as a preference, the pushing mechanism comprises:

[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 set is slidably arranged inside the fixed track;

[0025] The push panel is arranged on the inner side of the sealing surface, the top is fixedly connected to the bottom of the sliding wheel group, the side is fixedly connected to the extension shaft of the hydraulic cylinder, and the side opposite to the extension shaft corresponds to the pallet on the lifting platform at the top of the transmission assembly. That is to say, when the lifting platform drives the pallet to move to the highest point of the transmission assembly, the transmission assembly stops rotating at this time, and while receiving the pallet delivered from the conveying platform, the hydraulic cylinder drives the push panel to move in the direction of the conveying assembly line through the extension shaft, and at the same time, the sliding wheel group follows the push panel to move in the fixed track, while assisting the push panel to move, the moving direction of the push panel is restricted, and then, under the push of the push panel, the pallet leaves the lifting platform and enters the transfer box through the upper opening of the sealing surface.

[0026] Furthermore, as a preferred embodiment, 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 detects the wolfberries inside the tray. After ensuring that the wolfberries in the tray are intact, the conveying line is started, 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, and re-sorted after collection. At this time, the transfer box can wait for the arrival of the next tray and repeat the inspection work.

[0027] Furthermore, as a preferred embodiment, the output end of the protective housing and the end adjacent to the transfer box are respectively provided with a closed curtain. Under the action of the closed curtain, the temperature inside the protective housing is effectively ensured to always be kept at a low temperature that can preserve freshness, and the flow of air between the protective housing and the outside is hindered to a certain extent, so as to keep sufficient carbon dioxide gas inside the protective housing and reduce the oxidation probability of wolfberry during transportation.

[0028] Further, as a preference, the gas injection device comprises:

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

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

[0031] There are multiple induction nozzle assemblies distributed in a straight line along the gas injection pipeline and fixed at the bottom of the gas injection pipeline. That is to say, under the action of the external air pump, the carbon dioxide gas is transported to each gas injection pipeline, and then transported to the protective shell through the induction nozzle assembly, so that the protective shell is in a low-oxygen environment. At the same time, under the action of the cooling device, the temperature is reduced, thereby inhibiting the respiration of wolfberries, reducing the consumption of nutrients, and delaying the growth of microorganisms, so as to achieve the purpose of locking the freshness of wolfberries during the transportation process.

[0032] Further, as a preference, the induction nozzle assembly comprises:

[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 plurality in an annular distribution and are arranged in the nozzle body and are fixedly connected to the rotating mechanism, and the plurality of regulating blocks form a complete circular surface. That is to say, 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, so that the intervals between the regulating blocks become larger, the transportation of carbon dioxide gas is increased, and the carbon dioxide gas is cooled by the cooling device and then transported to various positions inside the protective shell, thereby inhibiting the oxidation of wolfberries while cooling; on the contrary, when the cooling device is not below the induction nozzle assembly, the induction ring does not sense the cooling device, and at this time the rotating mechanism drives the regulating blocks to rotate, so that the intervals between the regulating blocks become smaller, the transportation of carbon dioxide gas is reduced, and the carbon dioxide gas is slowly transported to the surface of the wolfberries on the tray below, effectively preventing the oxidation of the wolfberries during transportation.

[0037] Further, as a preference, the cooling device comprises:

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

[0039] The regulating frame is symmetrically provided with two, and the central connection is fixed at the bottom of the connecting shaft;

[0040] There are multiple cooling plates distributed in a straight line, which are rotatably arranged on the regulating frame, and the multiple cooling plates rotate synchronously. That is to say, driven by the connecting shaft, the regulating frame and the cooling plate rotate under the gas injection device. When the cooling plate is under the induction nozzle assembly, the corresponding induction nozzle assembly opens the regulating block to increase the interval between the regulating blocks and increase the delivery of carbon dioxide gas. After the carbon dioxide gas is cooled by the cooling plate, it is transported to the protective shell. The cooling plate can be rotated to adjust the delivery direction of the carbon dioxide gas after passing through the cooling plate, so that the cooled carbon dioxide gas is dispersed into the interior of the protective shell, maintaining a low-temperature environment while maintaining a low-oxygen environment, effectively locking the freshness of the wolfberry.

[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 the pallet and sent to the lifting and conveying mechanism through the setting of the conveying platform; the wolfberries are transported at a low temperature through the setting of the lifting and conveying mechanism, and during the transportation process, the wolfberries are sorted and the bad ones are removed; the sorted wolfberries are transported at a low temperature and anti-oxidation through the setting of the conveying assembly line, which effectively ensures that the wolfberries maintain good quality when they are transported to the processing equipment.

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

[0056] The conveying assembly line 5 is arranged on a 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 housing 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 housing 7 and is located above the conveying line 5;

[0060] A plurality of cooling devices 9 are linearly distributed and 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 assembly line 5, and a cooling air mechanism is provided inside;

[0063] The transmission components 22 are symmetrically arranged 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 is linearly arranged with a plurality of support platforms, and are fixed between the transmission assembly 22 and the inner wall of the fixed frame 21;

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

[0067] The sealing surface 26 is fixed on both sides of the fixed frame 21 adjacent to the conveying platform 1 and the conveying line 5. That is to say, the wolfberry refrigeration compartment conveys the refrigerated wolfberries after picking to the tray 4 on the conveying platform 1. Under the action of the conveying platform 1, the tray 4 is pushed to the lifting platform 23 between the transmission components 22, and then moved upward under the drive of the transmission component 22. During the upward movement of the lifting platform 23, the conveying platform 1 sequentially conveys the tray 4 to the remaining lifting platforms 23, that is, the transmission component 22 is in an intermittent operation state. When the transmission component 22 stops, the sorting mechanical arms 25 on the supporting 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 highest point of the transmission component 22, the tray 4 is pushed to the transfer box 6 on the conveying line 5 by the pushing mechanism 3 for subsequent conveying work. Under the action of the cold air mechanism inside the fixed frame 21, the interior of the lifting and conveying mechanism 2 is kept at a low temperature, which effectively locks the wolfberries and reduces the loss of wolfberries during the transportation process.

[0068] In this embodiment, the pushing mechanism 3 is fixed to the upper part of the sealing surface 26 close to the conveying platform 1, and the lower part of the sealing surface 26 close to the conveying platform 1 is provided with an opening corresponding to the tray 4 on the conveying platform 1, and the upper part of the sealing surface 26 close to the conveying line 5 is provided with an opening corresponding to the transfer box 6. With the cooperation of the sealing surface 26, the fixed frame 21 is closed, and while maintaining the internal temperature of the lifting and conveying mechanism 2, the cold air leakage is reduced, and the energy consumption of the cold air mechanism is reduced. In addition, the openings on the sealing surfaces 26 on both sides assist the tray 4 to be transported into the lifting and conveying mechanism 2, and output 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 track 31, and is located on the same side of the lifting and conveying mechanism 2 as the conveying platform 1;

[0072] A sliding wheel set 33, slidably arranged inside the fixed track 31;

[0073] The push panel 34 is arranged on the inner side of the sealing surface 26, and the top is fixedly connected to the bottom of the sliding wheel group 33, and the side is fixedly connected to the extension shaft of the hydraulic cylinder 32, and the side opposite to the extension shaft corresponds to the pallet 4 on the lifting platform 23 at the top of the transmission assembly 22. That is to say, 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 at this time, and while receiving the pallet 4 transported from the conveying platform 1, the hydraulic cylinder 32 drives the push panel 34 to move in the direction of the conveying assembly line 5 through the extension shaft, and at the same time, the sliding wheel group 33 follows the push panel 34 to move in the fixed track 31, and while assisting the push panel 34 to move, the moving direction of the push panel 34 is restricted, and then under the push of the push panel 34, the pallet 4 is separated from the lifting platform 23 and enters the transfer box 6 through the upper opening of the sealing surface 26.

[0074] In this embodiment, two scanning panels 61 that can be opened and closed are provided on the top of the transfer box 6, and a push-out mechanism is provided inside the transfer box 6. When the tray 4 enters the transfer box 6 under the action of the push mechanism 3, the conveying line 5 is in a stationary state, and 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 push-out mechanism inside the transfer box 6, and re-sorted after collection. At this time, the transfer box 6 waits for the arrival of the next tray 4 and repeats the detection work.

[0075] In this embodiment, the output end of the protective housing 7 and the end adjacent to the transfer box 6 are respectively provided with a closed curtain 71. Under the action of the closed curtain 71, the temperature inside the protective housing 7 is effectively ensured to always be kept at a low temperature that can preserve freshness, and the flow of air between the protective housing 7 and the outside is blocked to a certain extent, so that sufficient carbon dioxide gas is kept inside the protective housing 7, and the oxidation probability of wolfberries during transportation is reduced.

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

[0077] A plurality of gas injection pipelines 81 are linearly arranged and fixed in the protective housing 7, located at the upper part of the conveying line 5, and one end of the gas injection pipeline 81 is connected to an external air pump;

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

[0079] A plurality of induction nozzle assemblies 83 are linearly distributed along the gas injection pipeline 81 and fixed at the bottom of the gas injection pipeline 81. That is, under the action of the external air pump, the carbon dioxide gas is transported to each gas injection pipeline 81, and then transported to the protective shell 7 through the induction nozzle assembly 83, so that the protective shell 7 is in a low-oxygen environment, and at the same time, under the action of the cooling device 9, the temperature is reduced, thereby inhibiting the respiration of wolfberries, reducing the consumption of nutrients, and delaying the growth of microorganisms, so as to achieve the purpose of locking the freshness of wolfberries during the transportation process.

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

[0081] The nozzle body 831 is fixed at the bottom of the gas injection pipeline 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] There are a plurality of adjusting blocks 834, which are arranged in an annular distribution and are arranged in the nozzle body 831 and are fixedly connected to the rotating mechanism 833, and the plurality of adjusting blocks 834 form a complete circular surface. That is to say, 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 adjusting blocks 834 to rotate, so that the intervals between the adjusting blocks 834 become larger, the transportation of carbon dioxide gas is increased, and the carbon dioxide gas is cooled by the cooling device 9 and then transported to various positions inside the protective shell 7, thereby inhibiting the oxidation of wolfberry while cooling; on the contrary, 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 adjusting blocks 834 to rotate, so that the intervals between the adjusting blocks 834 become smaller, the transportation of carbon dioxide gas is reduced, and the carbon dioxide gas is slowly transported to the surface of the wolfberry on the tray 4 below, effectively preventing the wolfberry from oxidizing during transportation.

[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] The regulating frame 92 is symmetrically provided with two, and the central connection is fixed at the bottom of the connecting shaft 91;

[0088] There are multiple cooling plates 93 distributed in a straight line, which are rotatably arranged on the regulating frame 92, and multiple cooling plates 93 rotate synchronously. That is to say, driven by the connecting shaft 91, the regulating 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 regulating block 834, so that the interval between the regulating blocks 834 becomes larger, and the transportation of carbon dioxide gas is increased. After the carbon dioxide gas is cooled by the cooling plate 93, it is transported to the protective shell 7, and the transportation direction 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 shell 7, maintaining a low-temperature environment while maintaining a low-oxygen environment, and effectively locking the freshness of the wolfberry.

[0089] In 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 and 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 in 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, and re-sorted after collection. 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 the carbon dioxide gas to each gas injection pipe 81, and then transports it to 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 regulating 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 to increase the interval between the adjustment blocks 834 and increase the transportation of carbon dioxide gas. The transportation rate of the remaining induction nozzle assemblies 83 remains unchanged. After the carbon dioxide gas is cooled by the refrigeration plate 93, it is transported to the protective shell 7, and 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, and effectively locking the wolfberry until the tray 4 leaves the protective shell 7 and enters the processing mechanism under the drive of the conveying assembly line 5.
