Description

Technical Field

[0001] The present application relates to the technical field of wine lees conveying equipment, and in particular to a wine lees unloading and conveying system for a double-wheel bottom brewing process. Background Art

[0002] In traditional baijiu (white liquor) brewing, double-wheel bottom fermentation is a core process that extends the fermentation period of distiller's grains at the bottom of the pit to enhance the complexity of the liquor's flavor. This process requires stratifying distiller's grains at different depths within the pit: the upper layer, due to its greater exposure to oxygen, is less fermented and typically requires mixing with new grain for a secondary fermentation; the middle layer, with its moderate fermentation, can be directly used for distillation; and the bottom layer (especially the double-wheel bottom layer), due to its long-term anaerobic fermentation, is rich in flavor compounds such as esters and must be retained separately for use as flavoring liquor. Therefore, precisely capturing, separating, and conveying distiller's grains at different depths upon exiting the pit has become a key technical challenge in improving the standardization of the double-wheel bottom process and product stability.

[0003] Chinese invention patent publication number CN109251838B discloses a system for conveying mash into and out of a cellar. The system includes both a cellar-out system and a cellar-in system. The cellar-out system comprises a first mobile trolley, a telescopic arm, a first vertical lifting mechanism, and a grab bucket, with the bottom of the telescopic arm connected to the grab bucket. The cellar-in system comprises a second mobile trolley, a hopper, and a second vertical lifting mechanism, with the bottom of the hopper equipped with an electric door. The entire system also includes a transport trolley and a cleaning device. The provision of a gantry trolley and the first mobile trolley facilitates material transfer between the various cellars within the cellar chamber. The provision of a first vertical lifting mechanism drives the telescopic arm up and down, enabling the grabbing, lifting, and transfer of materials.

[0004] However, for the above-mentioned related technologies, although the material can be automatically grabbed by the grab bucket, the fermentation degree of the lees in the double-wheel bottom brewing process cellar is different at different depths, and the corresponding subsequent processing methods are different. However, the grab bucket relies on manual experience to judge the grabbing depth each time, which can easily lead to the destruction of the stratification characteristics of the lees in the cellar, causing the lees of different fermentation degrees to mix, affecting the subsequent process effects. Summary of the Invention

[0005] The present application provides a wine lees conveying system for a double-wheel bottom brewing process. The conveying system can carry out targeted grabbing according to the temperature of the wine lees layer with different fermentation degrees, thereby realizing accurate grabbing of different types of wine lees for separate conveying, and can dynamically adjust the temperature of the inner wall of the grab bucket to ensure that the wine lees will not produce flavor changes due to drastic temperature changes during the conveying process, thereby affecting the quality of the final wine.

[0006] The present application provides a double-wheel bottom brewing process distiller's grains conveying system using the following technical solutions: A double-wheel bottom brewing process distiller's grains conveying system, comprising: A sliding truss, wherein a sliding beam is slidably provided on the sliding truss, and a controller is provided on the sliding beam; a first lifting assembly, comprising a slide, a motor, and a lifting arm, wherein the slide is slidably mounted on the sliding beam, the motor is fixedly mounted on the slide, a drive gear is fixedly mounted on an output end of the motor, the motor is electrically connected to the controller, the lifting arm is slidably mounted on the slide in a vertical direction, a lifting rack is fixedly mounted on the lifting arm, and the lifting rack is meshed with the drive gear; A grab bucket comprises a bucket body, an upper support seat, a lower support seat, a pulling arm and a telescopic drive member, the bucket body is respectively provided with a grabbing end and a connecting end, the grabbing end and the connecting end are cross-arranged, a jaw plate is fixedly provided on the grabbing end of the bucket body, a plurality of groups of temperature sensors are provided on the jaw plate, the temperature sensor is electrically connected to the controller, a rotating part is provided on the bucket body, the rotating part is rotatably connected to the lower support seat, the bucket body is rotatably arranged on the lower support seat through the rotating part, the upper support seat is arranged above the lower support seat, the upper support seat is connected to one end of the lifting arm, one end of the pulling arm is rotatably connected to the bucket body connecting end, the other end of the pulling arm is rotatably connected to the upper support seat, and the telescopic drive member is arranged between the upper support seat and the lower support seat.

[0007] By adopting the above technical solution, the motor drives the gear to mesh with the lifting rack, which can accurately control the lifting stroke and ensure that the grab can accurately grab according to the different depths of the lees. At the same time, multiple sets of temperature sensors are integrated on the grab jaw plate, which can monitor the temperature differences of the lees at different depths in the cellar in real time, distinguish the fermentation degree of the lees based on the temperature characteristics, and then feed the temperature data back to the controller. Combined with the preset temperature threshold, the grabbing depth is dynamically adjusted to ensure that lees with different fermentation degrees can be grabbed independently, ensuring the standardization of the double-wheel bottom process. Compared with the traditional lees out of the cellar, which relies heavily on manual experience to judge the grabbing depth, this system uses motor drive and controller automatic calculation and temperature sensor judgment to achieve fully automatic and precise grabbing, reduce manual judgment errors, improve the degree of production standardization, and allow different grabbing modes to be set according to different lees levels, thereby realizing intelligent operation.

[0008] Optionally, it also includes a temperature control component, which includes a compressed air pump and an air duct, the compressed air pump is fixed on the slide, one end of the air duct is connected to the compressed air pump, a scraper plate is fixed on the lower support seat, the scraper plate abuts against the inner wall of the bucket, an air duct for exhaust is opened in the scraper plate, the air duct is connected to the end of the air duct away from the compressed air pump, a scraping blade portion is fixed on the scraper plate for scraping off residues on the inner wall of the bucket, a plurality of exhaust grooves are opened on the scraper blade portion, and the exhaust grooves are connected to the air duct.

[0009] By adopting the above technical solution, the compressed air pump and the air duct system can be used to adjust the airflow during the grabbing and conveying of the lees, effectively avoiding the change of flavor of the lees due to changes in ambient temperature during the grabbing and conveying process, and improving the stability of the brewing process; since the lees contain a certain amount of moisture and viscosity, they may adhere to the inner wall of the grab bucket after being grabbed for a long time, affecting the grabbing efficiency and the quality of the lees. The combined action of the scraper plate and the scraper blade can automatically scrape off the residue on the inner wall while the grab bucket releases the lees, and the setting of the exhaust groove allows the airflow to not only assist in cleaning the surface of the grab bucket, but also avoid lees adhesion, reduce the need for manual cleaning, and improve the service life of the equipment; in addition, since the fermentation degree of lees at different depths is different, the temperature of lees at different depths is also different. During the grabbing process, the temperature control component can adjust the interference caused by the residual heat of the lees when the grab bucket continues to work through the airflow, thereby ensuring the accuracy of layered grabbing and ensuring the stability of the double-wheel bottom fermentation process.

[0010] Optionally, the temperature control component further comprises a vortex tube, the vortex tube is arranged on the scraper plate, an air injection hole is opened at one end of the vortex tube, the axis of the air injection hole is tangent to the inner wall of the vortex tube, one end of the air guide pipe is connected to the compressed air pump, and the other end of the air guide pipe is connected to the air injection hole, a connecting seat is fixed on the inner wall of the vortex tube, the connecting seat is located at the end of the vortex tube away from the air injection hole, a flow block is fixed on the connecting seat, the flow block is set to a pointed cone shape, and the vortex tube A cold air pipe is provided at one end away from the connecting seat, one end of the cold air pipe is connected to the vortex tube, and the other end of the cold air pipe is connected to the air duct. When the air guide pipe injects compressed air into the vortex tube, a high-speed rotating compressed air vortex will be formed in the vortex tube, and the compressed air will be separated into two cold and hot air flows in the vortex tube. The baffle block will block the cold air flow from being discharged from the end of the vortex tube where the connecting seat is provided, thereby allowing the cold air flow to be discharged from the cold air pipe into the air duct.

[0011] By adopting the above technical solution, compared with the traditional grab bucket for grabbing wine lees, part of the wine lees will deteriorate due to equipment operation and ambient temperature changes, affecting the flavor of the wine, and the wine lees will easily adhere to the inside of the grab bucket due to their high moisture content and viscosity, affecting the smoothness of grabbing and releasing. This system separates the cold airflow through the vortex tube and introduces it into the air duct, so that the scraper can also cool the grab bucket while scraping the inner wall of the grab bucket, avoiding the impact of abnormal temperature on the fermentation flavor of the wine lees, reducing the wet and hot adhesion of the wine lees, ensuring that the wine lees can be separated from the grab bucket, and improving the conveying efficiency; in addition, the vortex tube is used to separate the hot and cold airflows, and a stable cold airflow can be provided without an additional cooling device, avoiding the high energy consumption problem of the traditional refrigeration method, effectively reducing production costs and improving production efficiency.

[0012] Optionally, the temperature control component also includes an adjusting part, which includes a sealing plate, an adjusting gear and an adjusting rack. An air outlet pipe is fixedly provided on the air outlet end of the compressed air pump, and the air outlet pipe is connected to the air guide pipe. An adjusting shaft is fixedly provided on the sealing plate, and the adjusting shaft is rotatably passed through the air outlet pipe. The sealing plate is rotatably mounted in the air outlet pipe through the adjusting shaft. The adjusting gear is transmission-connected to one end of the adjusting shaft, and the adjusting rack is fixed on the lifting arm, and the adjusting gear is meshed with the adjusting rack.

[0013] By adopting the above technical solution, the air output of the compressed air pump is adjusted by the rotation angle of the sealing plate, and the temperature can be finely controlled according to the fermentation status (temperature, humidity) of different lees layers to ensure that the lees treatment meets the needs of different fermentation degrees. In addition, the adjustment rack is fixed on the lifting arm, which means that the airflow adjustment can dynamically change with the lifting and lowering of the grab bucket. Lees of different depths can obtain corresponding airflow treatment, so that the subsequent temperature control of the grab bucket can be automatically adjusted.

[0014] Optionally, the temperature control component also includes a self-locking part, which includes a turbine, a worm, a driving bevel gear and a driven bevel gear. The turbine is fixedly connected to one end of the adjusting shaft, the worm is rotatably set on the slide, the worm is engaged with the turbine, and the driven bevel gear is fixedly connected to one end of the worm. A transmission shaft is rotatably set on the slide, one end of the transmission shaft is fixedly connected to the driving bevel gear, and the other end of the transmission shaft is fixedly connected to the adjusting gear.

[0015] By adopting the above technical solution, since the worm gear mechanism has a self-locking characteristic, after adjusting the sealing plate to control the air output, the adjustment state of the sealing plate can be stably maintained, avoiding airflow adjustment deviation due to external force, improving temperature control accuracy, and ensuring that the sealing plate is maintained in the set position without the need for additional components, reducing energy consumption and improving system stability; in addition, combined with the vortex tube temperature control system, the self-locking mechanism ensures a stable supply of airflow when the grab grabs the lees of the same depth, preventing the temperature control system from causing airflow fluctuations due to sliding of the adjustment parts, making the lees cooling or constant temperature treatment more accurate, and improving the stability of the wine flavor.

[0016] The transmission gear of claim 1, wherein the transmission gear comprises a first gear and a second gear and a second gear and a third gear and a plurality of conductor parts are arranged on the circumference of the fixed cylinder, and a plurality of second magnetic strips are arranged on the circumference of the fixed cylinder, and the magnetic poles of the two adjacent groups of second magnetic strips are arranged in opposite directions, and the number of the second magnetic strips is an integer multiple of the number of the first magnetic strips.

[0017] By adopting the above-mentioned technical solution, the inner cylinder, outer cylinder and fixed cylinder arranged inside the speed change part, together with the first magnetic strip and the second magnetic strip, are combined to form a magnetic coupling mechanism, which realizes dynamic adjustment of the transmission shaft speed, so that the system can adjust the airflow output speed according to different grasping conditions (such as lees temperature, fermentation level) to meet the needs of complex fermentation layering processes; at the same time, the speed change structure has overload slip protection capability, that is, it can avoid system damage due to jamming under extreme conditions, thereby improving the intelligent safety level of the overall system.

[0018] Optionally, the vortex tube is provided with a hot air pipe and an exhaust pipe at one end of the connecting seat, the exhaust pipe is arranged on the lower support seat, and a plurality of groups of nozzles are fixed on the exhaust pipe, and the plurality of groups of nozzles are evenly distributed on the surface of the lower support seat facing away from the upper support seat, and the exhaust pipe is connected to the end of the vortex tube provided with the connecting seat; the hot air pipe is arranged on the outer wall of the bucket body, and one end of the hot air pipe is connected to the end of the vortex tube provided with the connecting seat, and a plurality of groups of nozzles are fixed on the hot air pipe, and the nozzles are fixedly penetrated into the bucket body, and the output end of the nozzle is flush with the inner wall of the bucket body.

[0019] By adopting the above technical solution, the hot air flow separated by the vortex tube is injected into the exhaust pipe and the hot air pipe respectively, and distributed to the wine lees. In this way, firstly, when the grab is grabbing the wine lees, the wine lees are prevented from "waiting" and "transferring" during the intermittent working state of the grab, which causes the wine lees to be subjected to drastic changes in the ambient temperature, thereby affecting its flavor and quality. It also prevents water volatilization or fermentation abnormalities caused by temperature differences, thereby improving the consistency of material properties and the controllability of process control during the grabbing process. Secondly, the wine lees that have been grabbed into the grab can The ejected hot air forms a stable temperature-controlled environment, which helps to maintain the physical and chemical properties of the wine lees. For wine lees with certain agglomeration and caking, the hot air flow is released through the nozzles and sprinklers inside the grab bucket. Combined with the layout structure on the inner wall of the bucket, the wine lees can be partially blown away and debonded, avoiding the blockage of the grab bucket discharge port or the influence of weighing and subsequent transportation due to the lumpy wine lees, thereby achieving the simultaneous improvement of grabbing efficiency and transportation accuracy, effectively improving the stability, reliability and energy utilization efficiency of the system, and further enhancing the automation level and process quality of the double-wheel bottom brewing process.

[0020] Optionally, an air intake hood is provided on the vortex tube, and the air intake hood is arranged in a circular shape. The air injection holes are provided in multiple groups, and the multiple groups of air injection holes are distributed circumferentially on the vortex tube. The air intake hood is arranged on the air injection holes, and an air intake part is fixed on the air intake hood, and the air intake part is connected to the air intake hood, and the air intake part and the air guide pipe are away from one end of the compressed air pump.

[0021] By adopting the above technical solution, the setting of the air inlet hood evenly distributes the airflow, allowing compressed air to enter the vortex tube from multiple directions at the same time, which helps to form a more stable high-speed rotating airflow, avoid airflow deviation or turbulence, and improve the airflow separation effect of the vortex tube.

[0022] Optionally, the blocking plate is configured as a circular plate, and the diameter of the blocking plate is smaller than the inner diameter of the air outlet pipe.

[0023] By adopting the above technical solution, the blocking plate is smaller than the inner diameter of the air outlet pipe, ensuring that when the surface lees are being grabbed, a certain amount of compressed air is still injected into the vortex tube through the air outlet pipe, thereby ensuring the stability of the temperature control component.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The motor-driven gear meshes with the lifting rack to precisely control the lifting stroke, ensuring that the grab can accurately grab the lees according to the depth of the lees. At the same time, multiple sets of temperature sensors are integrated on the grab jaw plate to monitor the temperature differences of the lees at different depths in the cellar in real time. The fermentation degree of the lees is distinguished based on the temperature characteristics, and the temperature data is then fed back to the controller. Combined with the preset temperature threshold, the grab depth is dynamically adjusted to ensure that lees with different fermentation degrees can be grabbed independently, ensuring the standardization of the double-wheel bottom process. Compared with the traditional lees unloading process, which relies heavily on manual experience to judge the grab depth, this system uses motor drive and controller automatic calculation and temperature sensor judgment to achieve fully automatic and precise grabbing, reduce manual judgment errors, improve production standardization, and allow different grab modes to be set according to different lees levels, thereby realizing intelligent operation. 2. By injecting the hot air separated by the vortex tube into the exhaust pipe and hot air pipe respectively, and distributing it to the lees, a stable temperature-controlled environment can be formed in the grab bucket, ensuring that the physical and chemical properties of the lees are not significantly affected. In addition, for lees with certain agglomeration and agglomeration, the hot air flow released through the nozzles and sprinklers inside the grab bucket, combined with the layout structure on the inner wall of the bucket, can achieve localized blowing and debonding of the lees, preventing the lumps from clogging the grab bucket discharge port or affecting weighing and subsequent conveying. This achieves a simultaneous improvement in grabbing efficiency and conveying accuracy, effectively improving the stability, reliability and energy efficiency of the system, and further enhancing the automation level and process quality of the double-wheel bottom brewing process. 3. By discharging hot and cold airflows at different locations, the distiller's grains are effectively prevented from experiencing drastic temperature changes during the intermittent working period of the grab bucket, which could affect their flavor and quality. This prevents moisture volatilization or fermentation abnormalities caused by temperature differences, thereby improving the consistency of material properties during the grabbing process and the controllability of the process. 4. The air output of the compressed air pump is adjusted by the rotation angle of the sealing plate, and the temperature can be finely controlled according to the fermentation status (temperature and humidity) of different lees layers to ensure that the lees treatment meets the needs of different fermentation levels. In addition, the adjustment rack is fixed on the lifting arm, which means that the airflow adjustment can change dynamically with the lifting and lowering of the grab. Lees at different depths can receive corresponding airflow treatment, so that the temperature control of the grab can be automatically adjusted later. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed cylinder 571 is configured as a cylinder with an open end, and a fixing seat is detachably provided on the open end of the fixed cylinder 571 by means of bolts. The fixed cylinder 571 is fixedly mounted on the slide 31 through the fixing seat, and a rotating shaft 5711 is coaxially fixed in the fixed cylinder 571. The inner cylinder 573 is also configured as a cylinder with an open end, and the inner cylinder 573 is arranged in the fixed cylinder 571. The inner cylinder 573 is rotatably sleeved on the rotating shaft 5711, and a connecting shaft 5731 is fixed on the end of the inner cylinder 573 away from the fixed cylinder 571. The connecting shaft 5731 is rotatably passed through the fixed seat, and the connecting shaft 5731 passes through one end of the fixed seat and is fixedly connected to the driven bevel gear 564.

[0047] The outer cylinder 572 is also configured as a cylinder with one end open. The outer cylinder 572 is rotatably sleeved on the fixed cylinder 571. A transmission shaft 5721 is fixed to the end of the outer cylinder 572 away from the fixed cylinder 571. One end of the transmission shaft 5721 is fixedly connected to one end of the worm 562.

[0048] A plurality of groups of first magnetic strips 574 are arranged on the circumference of the inner cylinder 573, and the magnetic poles of two adjacent groups of first magnetic strips 574 are arranged in opposite directions. A plurality of groups of conductive parts 576 are arranged on the circumference of the fixed cylinder 571, and a plurality of groups of second magnetic strips 575 are arranged on the circumference of the outer cylinder 572, and the magnetic poles of two adjacent groups of second magnetic strips 575 are arranged in opposite directions. The number of second magnetic strips 575 is an integer multiple of the number of first magnetic strips 574.

[0049] In this embodiment, the first magnetic strip 574 and the second magnetic strip 575 are both set as permanent magnets, the conductor 576 is set as an iron rod, and the number of second magnetic strips 575 is twice the number of first magnetic strips 574. Of course, in other embodiments of the present application, the conductor 576 can also be set as other types of metal rods, as long as they can pass magnetism. At the same time, the number of second magnetic strips 575 can also be appropriately adjusted according to actual conditions.

[0050] A second mounting seat is also fixed on the slide 31, and a rotating shaft 565 is rotatably provided on the second mounting seat. One end of the rotating shaft 565 is fixedly connected to the active bevel gear 563, and the other end of the rotating shaft 565 is fixedly connected to the adjusting gear 552. The driven bevel gear 564 is meshed with the active bevel gear 563, and the adjusting rack 553 is fixed on the side of the lifting arm 33 close to the compressed air pump 51, and the adjusting gear 552 is meshed with the adjusting rack 553.

[0051] Since the fermentation degree and subsequent processing method of each layer of lees in the double-wheel bottom brewing process are different, different types of lees need to be accurately grabbed for separate storage and processing when leaving the cellar. Therefore, when grabbing lees at different depths, it is necessary to adjust the amount of compressed air in the air duct 52, that is, the deeper the depth, the greater the flow rate of compressed air in the air duct 52. When the deflection angle range of the sealing plate 551 is small, it is necessary to further increase the transmission ratio between the adjusting gear 552 and the sealing plate 551.

[0052] Therefore, a speed change member 57 is provided to change the transmission ratio between the two. The magnetic poles of two adjacent groups of magnetic strips with different numbers on the outer cylinder 572 and the inner cylinder 573 are opposite. When the inner cylinder 573 rotates to align a group of first magnetic strips 574 (N poles) with a group of conductive members 576, the group of conductive members 576 will attract a group of second magnetic strips 575 (S poles) with similar corresponding positions on the outer cylinder 572. At the same time, the group of first magnetic strips 574 (N poles) on the inner cylinder 573 will repel a group of second magnetic strips 575 (N poles) with similar corresponding positions on the outer cylinder 572. Similarly, when the inner cylinder 573 rotates, the outer cylinder 572 can be rotated by magnetism. The transmission ratio of the inner cylinder 573 to the outer cylinder 572 is exactly the ratio of the number of magnetic strips provided on the inner cylinder 573 to the outer cylinder 572.

[0053] It is worth noting that when using the grab 4 to grab other types of materials, there are actually many ways to control the temperature and gas output according to the materials at different depths being grabbed. For example, a servo motor and a matching sensor device are commonly used to dynamically sense the depth of the grabbed material, thereby dynamically controlling the temperature and gas output. However, in the environment of this embodiment, due to the use of a double-wheel bottom process, the bottom lees do not need to be taken out when the lees are taken out of the cellar, and the grab 4 cannot grab all the lees in the same fermentation layer at one time when grabbing the lees. This means that the relevant sensors used to determine the depth do not have an accurate positioning reference, and since it is lees fermentation, the relevant equipment cannot be preset in the cellar 6 in advance; if a sensor such as infrared detection is used, the lack of an accurate positioning reference will also lead to inaccurate detection. At the same time, temperature measurement is used to determine the depth of the grab 4. Since the top layer of lees will be directly exposed to the external environment after each grab, the real-time depth of the grab 4 cannot be accurately sensed. In addition, the use of servo motors and supporting sensor equipment, considering that the area used for lees fermentation is very large and there is a long window period for lees fermentation, will directly lead to a significant increase in the corresponding production costs and daily maintenance costs, seriously affecting the company's economic benefits.

There are multiple groups of air injection holes 531 in the vortex tube 53, and the multiple groups of air injection holes 531 are distributed in a circular shape on the vortex tube 53. The air intake cover 534 is arranged in a circular shape, and the air intake cover 534 is arranged on the air injection hole 531. An air intake part 5341 is fixed on the air intake cover 534, and the air intake part 5341 is connected to the air intake cover 534, and the air intake part 5341 is connected to the end of the air guide pipe 52 away from the compressed air pump 51.

[0055] A connecting seat 532 is fixedly provided on the inner wall of one end of the vortex tube 53 away from the air injection hole 531, and a baffle 533 is fixed on the connecting seat 532. The baffle 533 is set in a pointed cone shape, and the baffle 533 is mounted in the vortex tube 53 through the connecting seat 532. A cooling air pipe 54 is provided at one end of the vortex tube 53 where the air injection hole 531 is opened. One end of the cooling air pipe 54 is connected to the vortex tube 53, and the other end of the cooling air pipe 54 is connected to the air duct 481. The diameter of the cooling air pipe 54 is smaller than the diameter of the vortex tube 53, and the connection between the cooling air pipe 54 and the vortex tube 53 is set in a conical shape.

[0056] The vortex tube 53 is provided with a hot air pipe 59 and an exhaust pipe 58 at one end of the connecting seat 532. The exhaust pipe 58 is embedded in the lower support 43. A plurality of nozzles 581 are fixed on the exhaust pipe 58. The plurality of nozzles 581 are evenly distributed on the side of the lower support 43 away from the upper support 42. The exhaust pipe 58 is connected to the end of the vortex tube 53 provided with the connecting seat 532. The hot air pipe 59 is provided on the outer wall of the bucket 41. One end of the hot air pipe 59 is connected to the upper support 42. The vortex tube 53 is connected to one end of a connecting seat 532, and a plurality of nozzles 591 are fixedly provided on the hot air pipe 59. The nozzles 591 are fixedly penetrated on the bucket body 41, and the output end of the nozzle 591 is flush with the inner wall of the bucket body 41. There are multiple groups of hot air pipes 59 on each group of bucket bodies 41. The multiple groups of hot air pipes 59 are arranged at intervals along the circumferential direction of the bucket body 41, and the multiple groups of hot air pipes 59 are connected to each other. An isolation cover is also provided on the outer wall of the bucket body 41.

[0057] A diverter pipe 541 is also provided on the cold air pipe 54, and the diverter pipe 541 is connected to the cold air pipe 54. A first solenoid valve 542 is provided on the cold air pipe 54, and a second solenoid valve 543 is provided on the diverter pipe 541. The first solenoid valve 542 and the second solenoid valve 543 are both electrically connected to the controller 2. When the grab bucket 4 has grabbed the lees, the position sensors provided on the bucket body 41 will sense each other, so that the first solenoid valve 542, which is initially open, is closed, and the second solenoid valve 543, which is initially closed, is opened.

[0058] According to the expansion and compression effect of gas, when the air guide pipe 52 injects compressed air into the vortex tube 53, a high-speed rotating compressed air vortex will be formed in the vortex tube 53. Under the influence of centrifugal force, the compressed air will be separated into two cold and hot air flows in the vortex tube 53. The hot air flow will flow along the inner wall of the vortex tube 53, while the cold air flow will flow out of the axis of the vortex tube 53. The baffle 533 will block the cold air flow from the end of the vortex tube 53 where the connecting seat 532 is provided, so that the cold air flow is discharged from the cold air pipe 54 into the air duct 481, and the hot air flow is injected into the exhaust pipe 58 from the other end of the vortex tube 53. At the same time, in order to avoid the exhaust groove 483 from continuously discharging cold air to interfere with the detection of the temperature sensor 47, when the grab bucket 4 does not grab the lees, the first solenoid valve 542 is in a closed state, the second solenoid valve 543 is in an open state, and the cold air flow is discharged from the diversion pipe 541.

[0059] It is worth noting here that the heating or cooling of the compressed air is the conversion of internal energy, so the temperature difference is within a certain range.

[0060] The implementation principle of the wine lees unloading conveying system for the double-wheel bottom brewing process of the embodiment of the present application is as follows: the controller 2 controls the telescopic driving member 45 to drive the lower support seat 43 to move downward, the grab bucket 4 is opened to the maximum extent, the controller 2 controls the sliding beam 11 to move above the cellar 6, and then the controller 2 controls the motor 32 to start to make the lifting arm 33 move downward, the jaw plate 46 is inserted into the wine lees, and the temperature sensor 47 can detect the temperature of the wine lees in real time, so as to distinguish the wine lees layers with different fermentation degrees. At the same time, when the grab bucket 4 grabs on one side, the lifting arm 33 will also rise accordingly, so that when the grab bucket 4 grabs on one side, the moving trajectory of the jaw plate 46 remains straight to avoid insufficient grabbing; during the entire grabbing process of the grab bucket 4, the nozzle 581 provided on the lower support seat 43 and the nozzle 591 provided on the bucket body 41 will spray hot air flows of different degrees according to different depths. When the grab bucket 4 pours out the grabbed wine lees, the cold air flow is injected into the air duct 481 (the setting of the air duct 481 refers to Figure 8 ), and then the exhaust groove 483 on the scraping blade 482 will also spray out different degrees of cold air flow according to different depths to assist the scraping plate 48 to scrape off the lees residue on the inner wall of the bucket body 41, prevent the lees from gathering into scale on the inner wall of the grab bucket 4, and at the same time eliminate the interference caused by the residual heat of the lees to the temperature sensor 47 when the grab bucket 4 continues to work.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
