Description

Technical Field

[0001] The present application relates to the technical field of conveying mash into a cellar, and in particular to a system and method for conveying raw materials into a cellar based on a double-wheel bottom brewing process. Background Art

[0002] The double-wheel bottom brewing process is a traditional method in liquor brewing, which aims to improve the quality and yield of liquor by optimizing the fermentation conditions and fermentation cycle. This process focuses on the role of microorganisms in the fermentation process of the fermented grains. Through two different rounds of fermentation, the fermentation potential of the fermented grains is fully tapped to enhance the flavor and aroma of the wine.

[0003] In the double-wheel bottom fermentation process, the uniform distribution of the mash is crucial to the fermentation effect, especially when entering the cellar, ensuring the thickness of each layer of mash is consistent to ensure the uniformity of fermentation.

[0004] In the process of conveying the mash into the cellar, the hanging conveying system plays a vital role. The hanging conveying system adopts a double-station setting, including two parallel tracks and a conveying trolley installed on the track. Two grabs are installed under the conveying trolley to clamp the mash. The two grabs can accurately transfer the clamped mash to the corresponding cellar through precise design and control. After reaching the target position, the two grabs will open in time and accurately pour the clamped mash into the cellar to complete the unloading process.

[0005] However, in actual applications, after the mash is spread in the cellar, it often accumulates too high in the middle and is uneven on both sides. To solve this problem, two grabs need to clamp the mash that is too high in the middle and transfer it to the lower areas on both sides of the cellar. When the two grabs move to the edge of the cellar, they will open again, allowing the mash to fall from between the grabs to the lower part of the cellar, thereby filling the area. Afterwards, the hanging conveying system will also use the lower part of the two grabs to gently press and level the mash in the cellar to ensure uniform spreading and fermentation of the mash.

[0006] Although the existing hanging conveying system can realize the conveying and spreading of mash to a certain extent, there are still many problems in the actual operation process. In particular, when the two grabs clamp the mash in the middle of the cellar and fill it to the lower edge of the cellar, part of the mash is easy to spill to the edge of the cellar or even spill out of the cellar, causing unnecessary waste.

[0007] At the same time, when the two grabs are opened to a certain angle, some mash will still remain in the grabs, and the grabs need to be opened at a larger angle to achieve complete material discharge. However, doing so will cause the mash to spill out of the cellar. In order to avoid this waste, the grabs must be moved to the middle of the cellar during the opening process. However, such movement will prevent the mash from completely filling the low-lying areas, making the spreading process complicated and requiring repeated operations. This not only increases the difficulty of operation, but also prolongs the time of the entire conveying and spreading process, reducing production efficiency. Therefore, there is an urgent need to improve and optimize the existing hanging conveying system. Summary of the invention

[0008] In order to improve the efficiency of leveling the mash in the cellar, the present application provides a system and method for conveying raw materials into the cellar based on a double-wheel bottom brewing process.

[0009] The raw material conveying system based on the double-wheel bottom brewing process provided by the present application adopts the following technical solutions: A raw material conveying system for entering a cellar based on a double-wheel bottom brewing process, comprising a conveying trolley and two grab buckets installed below the conveying trolley, the outer side walls of the two grab buckets are both installed with leveling rollers for leveling, the conveying trolley is provided with an opening and closing mechanism for controlling the opening and closing of the two grab buckets, and the two grab buckets are provided with scraping mechanisms for scraping the raw materials in the grab buckets when the two grab buckets are gradually opened; The opening and closing mechanism includes a mounting base, a sliding seat, a telescopic member and a connecting rod. One end of the mounting base is connected to the conveying trolley, and the upper parts of the two grab buckets are rotatably mounted on the other end of the mounting base. The sliding seat is slidably mounted on the mounting base. The telescopic member is mounted on the mounting base and is used to drive the sliding seat to rise and fall. One end of the connecting rod is rotatably connected to the side wall of the sliding seat, and the other end is rotatably mounted on the upper end of the grab bucket. The grab bucket can drive the corresponding grab bucket to rotate through the connecting rod when the sliding seat is raised or lowered.

[0010] By adopting the above technical solution, when it is necessary to transfer the mash to the corresponding pit, the conveying trolley is controlled to move to the top of the pit, and then the grab bucket is controlled to descend to one end of the pit, at which time the telescopic member is extended, the telescopic member drives the sliding seat to move downward, and the sliding seat drives the connecting rod to rotate, so that the lower ends of the grab buckets are opened in the direction away from each other, so as to realize the unloading of the mash in the two grab buckets; During the unloading process, the conveying trolley drives the two grab buckets to move along the length direction of the cellar, so as to achieve uniform unloading of the mash in the cellar. During this process, the two leveling rollers will spread and level the mash unloaded into the cellar, making the mash in the cellar more uniform, thereby ensuring the fermentation effect of the mash in the cellar.

[0011] In this process, the scraping mechanism can scrape the fermented grains in the grab buckets when the two grab buckets are opened to discharge materials, thereby reducing the residual fermented grains in the grab buckets and enabling the two grab buckets to discharge materials without opening them at a large angle. After the unloading and preliminary spreading of the mash in the cellar are completed, the mash in the middle part of the cellar needs to be grabbed to the two side areas of the cellar so that the lower areas on both sides of the cellar are also filled with an equal amount of mash. At this time, the two grabs grab the mash in the middle part and then move it to the two sides of the cellar to move and unload the mash on the side areas of the cellar. During this process, the scraping mechanism can scrape the mash in the two grabs to reduce the residue of mash in the grabs, so that the two grabs do not need to open a large angle to unload, reducing the scattering of granular raw materials due to excessive opening of the angle.

[0012] Optionally, the scraping mechanism includes a scraper plate, a drive assembly, a reversing assembly and a cutting assembly. The scraper plate is slidably installed in the grab bucket, and the end of the scraper plate can slide along the inner wall of the grab bucket. The two grab buckets can drive the scraper plate to move toward a middle position close to the two grab buckets through the drive assembly when the two grab buckets are opened. The reversing assembly can drive the scraper plate to move away from the middle position of the two grab buckets when the two scraper plates are opened to a certain angle. The cutting assembly can cut off the power of the drive assembly when the two grab buckets rotate in a closing direction, so that the scraper plate will not move with the closing of the two grab buckets.

[0013] By adopting the above technical solution, when it is necessary to discharge the mash in the grab bucket, the two grab buckets are controlled to open gradually, and the mash located at the contact position of the two grab buckets will gradually be discharged into the cellar. During this process, the driving component drives the scraper plates in the two grab buckets to move in a direction close to each other, and finally move to a position close to each other, that is, the edge of each grab bucket, so that the mash in each grab bucket is pushed out from the two grab buckets, and the mash in the grab bucket is discharged; When it is necessary to grab the mash, first control the two grab buckets to open, then the driving component will control the two scraper plates to move towards each other, and continue to control the two grab buckets to open. When the opening angle between the two grab buckets reaches a certain value, the reversing component drives the two scraper plates to move away from each other, so that the scraper plates move from the material discharge edge close to each other in the grab bucket to the material discharge edge far away from the grab bucket. At this time, the scraper plates will not affect the material grabbing operation of the grab bucket; When the two grabs grab the mash, the ends of the two grabs that are away from each other rotate towards each other. At this time, the cutting component cuts off the connection between the driving component and the scraper plate. At this time, the driving component will not drive the scraper plate to move, so that the grab can grab the mash normally, and the scraper plate will not affect the grab action of the grab.

[0014] Optionally, the driving assembly includes an arcuate rack, a driven gear, a connecting piece and a driving wheel, the arcuate rack is slidably mounted on the side wall of the grab bucket, the two ends of the scraper plate are respectively fixedly connected to the two sides of the arcuate rack, the driven gear is rotatably mounted on the side wall of the grab bucket and meshes with the arcuate rack, the driving wheel is rotatably mounted on the side wall of the grab bucket and is transmission-connected to the rotating shaft of the grab bucket, the connecting piece is used to transmission-connect the driving wheel and the driven gear, and the reversing assembly is used to transmission-connect the rotating shaft of the grab bucket and drive the driving wheel to reciprocate.

[0015] By adopting the above technical solution, when the two grab buckets are opened, the reversing assembly drives the driving wheel to rotate in one direction first, and drives the linkage gear to rotate through the linkage member, so that the two sets of arc-shaped racks slide in the direction of approaching each other, so that the two sets of arc-shaped racks respectively drive the corresponding scraper plates to move, so that the two scraper plates move in the direction of approaching each other; When the two grab buckets continue to open, the reversing assembly will drive the driving wheel to rotate in the opposite direction, and drive the connecting gear to rotate through the connecting piece, so that the two sets of arc-shaped racks slide away from each other, and the two sets of arc-shaped racks respectively drive the corresponding scraper plates to move, thereby realizing the movement of the two scraper plates away from each other.

[0016] Optionally, the reversing assembly includes a first driving wheel, a second driving wheel and a shifting rod, the first driving wheel is rotatably mounted on the side wall of the mounting base, the second driving wheel is rotatably mounted on the side wall of the grab bucket, and the first driving wheel is coaxially arranged with the rotating shaft of the grab bucket, and the first driving wheel is meshed with the second driving wheel; There are multiple shifting rods, each of which is arranged at intervals on the wheel surface of the first driving wheel and the second driving wheel, and each of the shifting rods can be inserted into the wheel surface gap of the driving wheel to drive the driving wheel to reciprocate, and the cutting component is used to cut off the power on the grab bucket rotating shaft according to the rotation direction of the first driving wheel.

[0017] By adopting the above technical solution, when the two grab buckets are opened, the grab buckets drive the second driving wheel to rotate, and the second driving wheel will drive the lever to rotate when rotating. At the same time, the second driving wheel will drive the first driving wheel to rotate in the opposite direction. The multiple levers on the second driving wheel will mesh with the wheel surface gap of the driving wheel in turn, thereby driving the driving wheel to rotate in one direction, and finally causing the scraper plates to move in the direction of approaching each other. As the opening angle of the two grab buckets increases, the multiple levers on the second drive wheel rotate until they no longer mesh with the clearance of the driving wheel surface. At this time, the multiple levers on the first drive wheel will drive the driving wheel to rotate. Since the first drive wheel is meshed with the second drive wheel, the rotation direction of the first drive wheel is opposite to that of the second drive wheel. At this time, the first drive wheel drives the driving wheel to rotate in the opposite direction through the multiple levers, and finally causes the scraper plates to move away from each other.

[0018] Optionally, the cutting assembly includes an inner gear ring, a rotating shaft, a locking rod and an elastic member, the first driving wheel is rotatably sleeved on the rotating shaft of the grab bucket, and the inner gear ring is arranged on the inner circumferential wall of the first driving wheel, the rotating shaft is fixed on the rotating shaft of the grab bucket, one end of the locking rod is rotatably mounted on the rotating shaft, and can extend into the tooth surface of the inner gear ring during rotation, and the elastic member is used to drive the end of the locking rod away from the rotating shaft away from the rotating shaft of the grab bucket; When the grab bucket gradually opens, the rotating shaft of the grab bucket drives the locking rod to insert into the inner gear ring and lock the inner gear ring, so that the first drive wheel and the rotating shaft of the grab bucket are fixedly connected; when the grab bucket gradually closes, the rotating shaft of the grab bucket drives the locking rod to disengage from the tooth surface of the inner gear ring, so that the first drive wheel and the rotating shaft of the grab bucket are movably connected.

[0019] By adopting the above technical solution, when the grab bucket gradually opens, the rotating shaft of the grab bucket drives the locking rod to insert into the inner gear ring and lock the inner gear ring, so that the first drive wheel and the rotating shaft of the grab bucket are fixedly connected; when the grab bucket gradually closes, the rotating shaft of the grab bucket drives the locking rod to disengage from the tooth surface of the inner gear ring, so that the first drive wheel and the rotating shaft of the grab bucket are movably connected.

[0020] Optionally, a telescopic mechanism is provided between the scraper plate and the arc-shaped rack for driving the scraper plate to elastically abut against the inner wall of the grab bucket.

[0021] By adopting the above technical solution, the telescopic mechanism can make the end of the scraper plate elastically abut against the inner wall of the grab bucket, so that the scraper plate can clean the mash in the grab bucket more thoroughly during the process of scraping the mash without easily damaging the inner wall of the grab bucket.

[0022] Optionally, the telescopic mechanism includes a mounting plate and a tensioning spring, one end of the mounting plate is fixed to the side of the arc-shaped rack, and the other end is provided with an open groove for slidingly inserting the scraper plate, and the tensioning spring is installed in the open groove to make the end of the scraper plate away from the mounting plate extend out of the open groove and elastically abut against the inner wall of the grab bucket.

[0023] By adopting the above technical solution, when the scraper plate moves and scrapes along the inner wall of the grab bucket, the tensioning spring drives the end of the scraper plate to elastically abut against the inner wall of the grab bucket, so that the scraper plate can scrape the mash in the grab bucket more thoroughly without damaging the inner wall of the grab bucket.

[0024] Optionally, a pressing plate and a pressing mechanism for driving the pressing plate to press and squeeze out the mash between the two grabs when the two grabs are opened are installed in the middle position of the two grabs.

[0025] By adopting the above technical solution, when the two grabs are opened to discharge materials, the pressing mechanism will drive the pressing plate to move downward, thereby pressing the mash in the two grabs to discharge materials, which speeds up the discharge of the mash. When the two grabs are opened to grab the mash, although the pressing plate will move downward, when the two grabs are closed to grab the mash, the pressing mechanism will drive the pressing plate to move upward, which will not affect the normal grabbing of the mash by the grab.

[0026] Optionally, the pressing mechanism includes a socket and a double-sided rack slidably engaged in the socket, the socket is installed on the side wall of the mounting base, the double-sided rack is respectively engaged with the two first driving wheels, and the end of the double-sided rack away from the socket is fixedly connected to the pressing plate.

[0027] By adopting the above technical solution, when the two grab buckets are opened, the first driving wheel drives the double-sided rack to move downward, thereby driving the pressing plate to press downward to realize the discharge of the mash; when the two grab buckets are closed, the first driving wheel drives the double-sided rack to move downward, thereby driving the pressing plate to move upward.

[0028] The present application also provides a method for conveying raw materials into a cellar based on a double-wheel bottom brewing process, comprising the following steps: S1: The opening and closing mechanism on the conveying trolley clamps and transfers the mash, so that the mash moves from the pile to the top of the corresponding cellar; S2: Control the two grabs on the conveying trolley to open, and discharge the fermented grains in the two grabs into the cellar, and repeatedly clamp and transfer the fermented grains to pile up the required amount in the cellar; S3: Control the two grab buckets to open and grab the mash in the cellar, and control the conveying trolley to move the two grab buckets to the edge of the cellar so that the middle position of the two grab buckets is close to the sunken position in the cellar; S4: Control the two grab buckets to open so that the mash in the middle of the two grab buckets is filled to the sunken position on the side of the cellar. During the opening of the two grab buckets, the scraping mechanisms provided in the two grab buckets will automatically scrape the mash in the corresponding grab buckets as the corresponding grab buckets gradually open, and repeatedly fill the sunken position in the cellar until the mash in the cellar is filled up. S5: Control the two grab buckets to close, and continuously change the horizontal and vertical positions of the two grab buckets through the conveying trolley, so that the bottoms of the two grab buckets continuously press and level the surface of the mash in the cellar until the surface of the mash in the cellar is flat.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the mash in the grab bucket needs to be unloaded, the two grab buckets are controlled to open gradually. At this time, the mash located at the contact position of the two grab buckets will gradually be unloaded into the cellar. During this process, the drive assembly drives the scraper plates in the two grab buckets to move toward each other, and finally move to a position close to each other, that is, the edge of each grab bucket, so that the mash in each grab bucket is pushed out of the two grab buckets, and the mash in the grab bucket is unloaded; When it is necessary to grab the mash, first control the two grab buckets to open, then the driving component will control the two scraper plates to move towards each other, and continue to control the two grab buckets to open. When the opening angle between the two grab buckets reaches a certain value, the reversing component drives the two scraper plates to move away from each other, so that the scraper plates move from the material discharge edge close to each other in the grab bucket to the material discharge edge far away from the grab bucket. At this time, the scraper plates will not affect the material grabbing operation of the grab bucket; When the two grabs grab the mash, the ends of the two grabs that are away from each other rotate towards each other. At this time, the cutting component cuts off the linkage between the driving component and the scraper plate. At this time, the driving component will not drive the scraper plate to move, so that the grab can grab the mash normally, and the scraper plate will not affect the grab action of the grab; 2. The scraping mechanism in the present application can scrape the fermented grains in the grab bucket. Compared with using ordinary power parts to drive the scraping plate to scrape the fermented grains in the grab bucket, this structure is more suitable for scraping such granular raw materials. Ordinary power parts are easily damaged in the grab bucket full of granular raw materials. 3. The scraping mechanism and pressing mechanism in the present application can complete all actions when the two grab buckets rotate, reducing the additional input of the external power source and greatly saving the use of energy; 4. The telescopic mechanism can make the end of the scraper plate elastically abut against the inner wall of the grab bucket, so that the scraper plate can clean the mash in the grab bucket more thoroughly during the scraping process without easily damaging the inner wall of the grab bucket; 5. When the two grab buckets are opened to discharge materials, the pressing mechanism will drive the pressing plate to move downward, thereby pressing the mash in the two grab buckets to discharge the materials, speeding up the discharge speed of the mash; when the two grab buckets are opened to grab the mash, although the pressing plate will move downward at this time, but when the two grab buckets grab the mash and close, the pressing mechanism will drive the pressing plate to move upward, which will not affect the normal grabbing of the mash by the grab buckets.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-8 , further details of this application are given.

[0034] The present application embodiment discloses a raw material conveying system based on a double-wheel bottom brewing process, referring to Figure 1, Figure 2 and Figure 3 , including a track 1, a conveying trolley 11 and two grab buckets 12 installed under the conveying trolley 11, leveling rollers 121 for leveling are installed on the outer walls of the two grab buckets 12, an opening and closing mechanism 2 for controlling the opening and closing of the two grab buckets 12 is provided on the conveying trolley 11, and a scraping mechanism 3 is provided in the two grab buckets 12 for scraping the raw materials in the grab buckets 12 when the two grab buckets 12 are gradually opened.

[0035] Reference Figure 3 , Figure 4 and Figure 5 The opening and closing mechanism 2 includes a mounting base 21, a sliding seat 22, a telescopic member 23 and a connecting rod 24. One end of the mounting base 21 is connected to the conveying trolley 11. The upper parts of the two grab buckets 12 are rotatably mounted on the other end of the mounting base 21. The sliding seat 22 is slidably mounted on the mounting base 21. The telescopic member 23 is mounted on the mounting base 21 and is used to drive the sliding seat 22 to rise and fall. One end of the connecting rod 24 is rotatably connected to the side wall of the sliding seat 22, and the other end is rotatably mounted on the upper end of the grab bucket 12. The grab bucket 12 can drive the corresponding grab bucket 12 to rotate through the connecting rod 24 when the sliding seat 22 rises and falls.

[0036] When the mash needs to be transferred to the corresponding cellar, the conveying trolley 11 is controlled to move to the top of the cellar, and then the grab 12 is controlled to descend to one end of the cellar. At this time, the telescopic member 23 is extended, and the telescopic member 23 drives the sliding seat 22 to move downward, and the sliding seat 22 drives the connecting rod 24 to rotate, so that the lower ends of the grabs 12 are opened in the direction away from each other, so as to realize the unloading of the mash in the two grabs 12; During the unloading process, the conveying trolley 11 drives the two grab buckets 12 to move along the length direction of the cellar, so as to achieve uniform unloading of the mash in the cellar. During this process, the two leveling rollers 121 will spread and level the mash unloaded into the cellar, making the mash in the cellar more uniform, thereby ensuring the fermentation effect of the mash in the cellar.

[0037] In this process, the scraping mechanism 3 can scrape the fermented grains in the grab bucket 12 when the two grab buckets 12 are opened to discharge materials, thereby reducing the residual fermented grains in the grab bucket 12, so that the two grab buckets 12 can discharge materials without opening a large angle; After the unloading and preliminary spreading of the mash in the cellar are completed, the mash in the middle part of the cellar needs to be grabbed to the two side areas of the cellar so that the lower areas on both sides of the cellar are also filled with an equal amount of mash. At this time, the two grabs 12 grab the mash in the middle part and then move it to the two sides of the cellar to move and unload the mash on the side areas of the cellar. During this process, the scraping mechanism 3 can scrape the mash in the two grabs 12 to reduce the residual mash in the grab 12, so that the two grabs 12 do not need to open a large angle to achieve unloading, thereby reducing the scattering of granular raw materials due to excessive opening of the angle.

[0038] Reference Figure 4 , Figure 5 and Figure 6 The scraping mechanism 3 includes a scraper plate 31, a driving assembly 32, a reversing assembly 33 and a cutting assembly 34. The scraper plate 31 is slidably installed in the grab bucket 12, and the end of the scraper plate 31 can slide along the inner wall of the grab bucket 12. The two grab buckets 12 can drive the scraper plate 31 to move to a middle position close to the two grab buckets 12 through the driving assembly 32 when they are opened. The reversing assembly 33 can drive the scraper plate 31 to move to a middle position away from the two grab buckets 12 when the two scraper plates 31 are opened at a certain angle. The cutting assembly 34 can cut off the power of the driving assembly 32 when the two grab buckets 12 rotate in the closing direction, so that the scraper plate 31 will not move with the closing of the two grab buckets 12.

[0039] When the mash in the grab bucket 12 needs to be discharged, the two grab buckets 12 are controlled to open gradually, and the mash located at the contact position of the two grab buckets 12 will gradually be discharged into the cellar. During this process, the drive assembly 32 drives the scraper plates 31 in the two grab buckets 12 to move toward each other, and finally move to a position close to each other, that is, the edge of each grab bucket 12, so that the mash in each grab bucket 12 is pushed out from the two grab buckets 12, and the mash in the grab bucket 12 is discharged; When it is necessary to grab the mash, the two grab buckets 12 are first controlled to open. At this time, the driving component 32 controls the two scraper plates 31 to move in a direction close to each other, and continues to control the two grab buckets 12 to open. When the opening angle between the two grab buckets 12 reaches a certain value, the reversing component 33 drives the two scraper plates 31 to move away from each other, so that the scraper plates 31 move from the material discharge edge close to each other in the grab bucket 12 to the material discharge edge away from the grab bucket 12. At this time, the scraper plates 31 will not affect the material grabbing operation of the grab bucket 12; When the two grab buckets 12 grab the mash, the ends of the two grab buckets 12 that are away from each other rotate towards each other. At this time, the cutting component 34 cuts off the connection between the driving component 32 and the scraper plate 31. At this time, the driving component 32 will not drive the scraper plate 31 to move, so that the grab bucket 12 can grab the mash normally, and the scraper plate 31 will not affect the grab bucket 12's movement.

[0040] Reference Figure 5 , Figure 6 and Figure 7 The driving assembly 32 includes an arc-shaped rack 321, a driven gear 322, a connecting piece 323 and a driving wheel 324. The arc-shaped rack 321 is slidably mounted on the side wall of the grab bucket 12. The two ends of the scraper plate 31 are respectively fixedly connected to the sides of the two arc-shaped racks 321. The driven gear 322 is rotatably mounted on the side wall of the grab bucket 12 and meshes with the arc-shaped rack 321. The driving wheel 324 is rotatably mounted on the side wall of the grab bucket 12 and is transmission-connected to the rotating shaft of the grab bucket 12. The connecting piece 323 is used for transmission connection between the driving wheel 324 and the driven gear 322. The connecting piece 323 adopts a belt transmission method. The reversing assembly 33 is used for transmission connection with the rotating shaft of the grab bucket 12 and drives the driving wheel 324 to reciprocate.

[0041] When the two grab buckets 12 are opened, the reversing assembly 33 drives the driving wheel 324 to rotate in one direction first, and drives the linkage gear to rotate through the linkage member 323, so that the two sets of arc-shaped racks 321 slide in the direction of approaching each other, so that the two sets of arc-shaped racks 321 respectively drive the corresponding scraper plates 31 to move, so that the two scraper plates 31 move in the direction of approaching each other; When the two grab buckets 12 continue to open, the reversing assembly 33 will drive the driving wheel 324 to rotate in the opposite direction, and drive the connecting gear to rotate through the connecting piece 323, so that the two sets of arc-shaped racks 321 slide in the direction away from each other, and the two sets of arc-shaped racks 321 respectively drive the corresponding scraper plates 31 to move, thereby realizing the movement of the two scraper plates 31 in the direction away from each other.

[0042] Reference Figure 5 , Figure 6 and Figure 7 The reversing assembly 33 includes a first driving wheel 331, a second driving wheel 332 and a shifting rod 333. The first driving wheel 331 is rotatably mounted on the side wall of the mounting base 21, and the second driving wheel 332 is rotatably mounted on the side wall of the grab bucket 12. The first driving wheel 331 is coaxially fixed with the rotating axis of the grab bucket 12, and the first driving wheel 331 and the second driving wheel 332 are meshed.

[0043] There are multiple levers 333, and each lever 333 is arranged at intervals on the wheel surface of the first driving wheel 331 and the second driving wheel 332, and each lever 333 can be inserted into the wheel surface gap of the driving wheel 324 to drive the driving wheel 324 to reciprocate. The cutting component 34 is used to cut off the power on the rotating shaft of the grab bucket 12 according to the rotation direction of the first driving wheel 331.

[0044] When the two grab buckets 12 are opened, the grab buckets 12 drive the second driving wheel 332 to rotate, and the second driving wheel 332 drives the lever 333 to rotate. At the same time, the second driving wheel 332 drives the first driving wheel 331 to rotate in the opposite direction. The multiple levers 333 on the second driving wheel 332 will mesh with the wheel surface gap of the driving wheel 324 in turn, thereby driving the driving wheel 324 to rotate in one direction, and finally the scraper plates 31 move in a direction close to each other. As the opening angle of the two grab buckets 12 increases, the multiple levers 333 on the second drive wheel 332 rotate until they no longer mesh with the wheel surface gap of the driving wheel 324. At this time, the multiple levers 333 on the first drive wheel 331 will drive the driving wheel 324 to rotate. Since the first drive wheel 331 is meshed with the second drive wheel 332, the rotation direction of the first drive wheel 331 is opposite to that of the second drive wheel 332. At this time, the first drive wheel 331 drives the driving wheel 324 to rotate in the opposite direction through the multiple levers 333, and finally the scraper plates 31 move in the direction away from each other.

[0045] Reference Figure 6 , Figure 7 and Figure 8 The cutting assembly 34 includes an inner gear ring 341, a rotating shaft 342, a locking rod 343 and an elastic member 344. The first driving wheel 331 is rotatably sleeved on the rotating shaft of the grab bucket 12, and the inner gear ring 341 is arranged on the inner circumferential wall of the first driving wheel 331. The rotating shaft 342 is fixed on the rotating shaft of the grab bucket 12. One end of the locking rod 343 is rotatably installed on the rotating shaft 342 and can extend into the tooth surface of the inner gear ring 341 during the rotation process. The elastic member 344 is used to drive the end of the locking rod 343 away from the rotating shaft 342 away from the rotating shaft of the grab bucket 12.

[0046] When the grab bucket 12 gradually opens, the rotating shaft of the grab bucket 12 drives the locking rod 343 to insert into the inner gear ring 341 and lock the inner gear ring 341, so that the first drive wheel 331 and the rotating shaft of the grab bucket 12 are fixedly connected. When the grab bucket 12 gradually closes, the rotating shaft of the grab bucket 12 drives the locking rod 343 to disengage from the tooth surface of the inner gear ring 341, so that the first drive wheel 331 and the rotating shaft of the grab bucket 12 are movably connected.

[0047] A telescopic mechanism 4 is provided between the scraper plate 31 and the arc-shaped rack 321 to drive the scraper plate 31 to elastically abut against the inner wall of the grab bucket 12. Figure 5 and Figure 6 The telescopic mechanism 4 includes a mounting plate 41 and a tensioning spring. One end of the mounting plate 41 is fixed to the side of the arc-shaped rack 321, and the other end is provided with an open groove for slidingly inserting the scraper plate 31. The tensioning spring is installed in the open groove to make the end of the scraper plate 31 away from the mounting plate 41 extend out of the open groove and elastically abut against the inner wall of the grab bucket 12.

[0048] When the scraper plate 31 moves and scrapes along the inner wall of the grab bucket 12, the tensioning spring drives the end of the scraper plate 31 to elastically abut against the inner wall of the grab bucket 12, so that the scraper plate 31 can scrape the mash in the grab bucket 12 more thoroughly without damaging the inner wall of the grab bucket 12.

[0049] A pressing plate and a pressing mechanism 5 for driving the pressing plate to press and squeeze out the mash between the two grabs 12 when the two grabs 12 are opened are installed in the middle position of the two grabs 12. Figure 5 , Figure 6 and Figure 7 The pressing mechanism 5 includes a socket 51 and a double-sided rack 52 that is slidably engaged in the socket 51. The socket 51 is installed on the side wall of the mounting base 21. The double-sided rack 52 is respectively engaged with the two first driving wheels 331, and one end of the double-sided rack 52 away from the socket 51 is fixedly connected to the pressing plate.

[0050] When the two grab buckets 12 are opened to discharge the material, the pressing mechanism 5 will drive the pressing plate to move downward, thereby pressing the mash in the two grab buckets 12 to discharge the material, thereby accelerating the discharge speed of the mash. When the two grab buckets 12 are opened to grab the mash, although the pressing plate will move downward at this time, when the two grab buckets 12 grab the mash and close, the pressing mechanism 5 will drive the pressing plate to move upward, which will not affect the normal grabbing of the mash by the grab bucket 12.

[0051] Furthermore, in order to enable the leveling roller 121 to assist in leveling the mash in the cellar during the opening and closing of the two grab buckets 12, a linkage mechanism 6 is provided at one end of the connecting rod 24 away from the mounting base 21 and the end of the leveling roller 121. The linkage mechanism 6 includes a first linkage wheel 61, a linkage belt 62 and a second linkage wheel 63. The first linkage wheel 61 is coaxially fixed with the rotating shaft of the connecting rod 24, and the second linkage wheel 63 is coaxially fixed with the end of the leveling roller 121. The linkage belt 62 is respectively connected to the first linkage wheel 61 and the second linkage wheel 63 for transmission, and the diameter of the first linkage wheel 61 is much larger than the diameter of the second linkage wheel 63. In the present embodiment, the diameter of the first linkage wheel 61 is four times the diameter of the second linkage wheel 63.

[0052] When the two grab buckets 12 are opened or closed, the first interlocking wheel 61 can drive the second interlocking wheel 63 to rotate through the interlocking belt 62. Since the diameter of the first interlocking wheel 61 is much larger than the diameter of the second interlocking wheel 63, the first interlocking wheel 61 can drive the second interlocking wheel 63 to rotate a larger angle or a larger number of circles at a smaller rotation angle.

[0053] When the two grab buckets 12 are open, it is in the waiting for clamping or unloading stage. If it is in the waiting for clamping stage, the leveling roller 121 will push the mash to the two sides of the cellar, so as to achieve auxiliary filling of the positions that need to be filled on both sides; when the two grab buckets 12 are closed, it is in the loading stage. At this time, the leveling roller 121 will push the mash to the middle of the cellar, that is, to the loading position of the two grab buckets 12, so that the low-lying areas formed by the clamping of the two grab buckets 12 can be adjusted and compensated, which is convenient for the next clamping of the two grab buckets 12.

[0054] The implementation principle of the raw material conveying system for entering the cellar based on the double-wheel bottom brewing process in the embodiment of the present application is as follows: when the mash needs to be transferred to the corresponding cellar, the conveying trolley 11 is controlled to move to the top of the cellar, and then the grab 12 is controlled to descend to one end of the cellar, at which time the telescopic member 23 is extended, and the telescopic member 23 drives the sliding seat 22 to move downward, and the sliding seat 22 drives the connecting rod 24 to rotate, so that the lower ends of the grabs 12 are opened in a direction away from each other, so as to realize the unloading of the mash in the two grabs 12; During the unloading process, the conveying trolley 11 drives the two grab buckets 12 to move along the length direction of the cellar, so as to achieve uniform unloading of the mash in the cellar. During this process, the two leveling rollers 121 will spread and level the mash unloaded into the cellar, making the mash in the cellar more uniform, thereby ensuring the fermentation effect of the mash in the cellar.

[0055] In this process, the scraping mechanism 3 can scrape the fermented grains in the grab bucket 12 when the two grab buckets 12 are opened to discharge materials, thereby reducing the residual fermented grains in the grab bucket 12, so that the two grab buckets 12 can discharge materials without opening a large angle; After the unloading and preliminary spreading of the mash in the cellar are completed, the mash in the middle part of the cellar needs to be grabbed to the two side areas of the cellar so that the lower areas on both sides of the cellar are also filled with an equal amount of mash. At this time, the two grabs 12 grab the mash in the middle part and then move it to the two sides of the cellar to move and unload the mash on the side areas of the cellar. During this process, the scraping mechanism 3 can scrape the mash in the two grabs 12 to reduce the residual mash in the grab 12, so that the two grabs 12 do not need to open a large angle to achieve unloading, thereby reducing the scattering of granular raw materials due to excessive opening of the angle.

[0056] The embodiment of the present application also discloses a method for conveying raw materials into a cellar based on a double-wheel bottom brewing process, which uses the above-mentioned raw material conveying system for conveying raw materials into a cellar based on a double-wheel bottom brewing process for conveying, and includes the following steps: S1: The opening and closing mechanism 2 on the conveying trolley 11 clamps and transfers the fermented grains, so that the fermented grains are moved from the material pile to the top of the corresponding cellar; S2: Control the two grab buckets 12 on the conveying trolley 11 to open, and discharge the fermented grains in the two grab buckets 12 into the cellar, and repeatedly clamp and transfer the fermented grains to pile up the required amount in the cellar; S3: Control the two grab buckets 12 to open and grab the mash in the cellar, and control the conveying trolley 11 to move the two grab buckets 12 to the edge of the cellar so that the middle position of the two grab buckets 12 is close to the sunken position in the cellar; S4: Control the two grab buckets 12 to open so that the mash in the middle of the two grab buckets 12 is filled to the sunken position on the side of the cellar. During the opening of the two grab buckets 12, the scraping mechanism 3 provided in the two grab buckets 12 will automatically scrape the mash in the corresponding grab bucket 12 as the corresponding grab bucket 12 gradually opens, and repeatedly fill the sunken position in the cellar until the mash in the cellar is filled up. S5: Control the two grab buckets 12 to close, and continuously change the horizontal and vertical positions of the two grab buckets 12 through the conveying trolley 11, so that the bottoms of the two grab buckets 12 continuously press and level the surface of the mash in the cellar until the surface of the mash in the cellar is flat.

[0057] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
