Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fermented grains conveying into pits, in particular to a raw material conveying system and method based on double-bottom brewing process. BACKGROUND

[0002] Double-bottom brewing process is a traditional method in liquor brewing, aiming to optimize fermentation conditions and fermentation cycle to improve the quality and yield of liquor. This process focuses on the role of microorganisms in the fermentation process of fermented grains, fully tapping the fermentation potential of fermented grains through two different rounds of fermentation process, and improving the flavor and aroma of liquor.

[0003] In the double-bottom fermentation process, uniform distribution of fermented grains is crucial to the fermentation effect, especially when entering the pit, ensuring the uniformity of each layer of fermented grains to ensure the uniformity of fermentation.

[0004] During the conveying of fermented grains into the pit, the suspended conveying system plays a crucial role. The suspended conveying system adopts a double-station setting, including two parallel tracks and a conveying trolley installed on the tracks. The conveying trolley is equipped with two grab buckets below it that can clamp fermented grains. Through precise design and control, the two grab buckets can accurately transfer the clamped fermented grains to the corresponding pit. After reaching the target position, the two grab buckets will open in time to accurately pour the clamped fermented grains into the pit, completing the unloading process.

[0005] However, in actual application, after the fermented grains are spread into the pit, there is often a problem of excessive accumulation in the middle and unevenness on both sides. To solve this problem, the two grab buckets need to clamp the fermented grains that are excessively accumulated in the middle and transfer them to the lower areas on both sides of the pit. When the two grab buckets move to the edge of the pit, they will open again, causing the fermented grains to fall from between the grab buckets to the lower part of the pit, thereby filling the area. After that, the suspended conveying system will use the lower part of the two grab buckets to lightly press and flatten the fermented grains in the pit to ensure uniform spreading and fermentation effect of the fermented grains.

[0006] Although the existing suspended conveying system can achieve the conveying and spreading of fermented grains to some extent, there are still many problems in the actual operation process. In particular, when the two grab buckets clamp the fermented grains in the middle of the pit and fill them to the lower part of the edge of the pit, some fermented grains are easily spilled to the edge of the pit or even outside the pit, causing unnecessary waste.

[0007] Meanwhile, when the two grab buckets open to a certain angle, some mash will still remain inside, requiring the grab buckets to open to a greater angle to completely discharge the mash. However, this causes the mash to spill outside the fermentation pit. To avoid this waste, it must be moved towards the center of the pit during the opening of the grab buckets. However, such movement prevents the mash from completely filling low-lying areas, making the spreading process complex and requiring repeated operations. This not only increases the operational difficulty but also prolongs the entire conveying and spreading process, reducing production efficiency. Therefore, it is urgent to improve and optimize the existing overhead conveying system. Summary of the Invention

[0008] To improve the efficiency of leveling the mash in the fermentation pit, this application provides a raw material feeding and conveying system and method based on the double-bottom brewing process.

[0009] The raw material feeding and conveying system based on the double-bottom brewing process provided in this application adopts the following technical solution:

[0010] A raw material feeding and conveying system based on a double-wheel bottom brewing process includes a conveying trolley and two grab buckets installed below the conveying trolley. The outer walls of the two grab buckets are equipped with leveling rollers for leveling. The conveying trolley is equipped with an opening and closing mechanism for controlling the opening and closing of the two grab buckets. The two grab buckets are equipped with scraping mechanisms for scraping the raw materials inside the grab buckets as the two grab buckets gradually open.

[0011] The opening and closing mechanism includes a mounting base, a sliding seat, a telescopic component, and a connecting rod. One end of the mounting base is connected to the conveying trolley. The upper parts of the two grabs are rotatably mounted on the other end of the mounting base. The sliding seat is slidably mounted on the mounting base. The telescopic component 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. The grab can drive the corresponding grab to rotate through the connecting rod when the sliding seat rises and falls.

[0012] By adopting the above technical solution, when it is necessary to transfer the mash to the corresponding fermentation pit, the conveying trolley is controlled to move directly above the fermentation pit, and then the grab bucket is controlled to descend to one end of the fermentation pit. At this time, the telescopic component extends, and the telescopic component drives the sliding seat to move downward. The sliding seat drives the connecting rod to rotate, so that the lower end of the grab bucket opens in a direction away from each other, realizing the feeding of mash into the two grab buckets.

[0013] During the feeding process, the conveyor trolley drives two grab buckets to move along the length of the fermentation pit, thereby achieving uniform feeding of the mash in the pit. During this process, two leveling rollers spread and level the mash fed into the pit, making the mash in the pit more uniform, so as to ensure the fermentation effect of the mash in the pit.

[0014] During this process, the scraping mechanism can scrape the mash in the grab buckets when the two grab buckets open to discharge the material, reducing the residue of mash in the grab buckets and allowing the two grab buckets to discharge the material without opening them at a large angle.

[0015] After the mash in the fermentation pit is fed and initially spread, the mash in the middle of the pit needs to be grabbed and moved to the two sides of the pit so that the lower areas on both sides are also filled with an equal amount of mash. At this time, the two grabs grab the mash in the middle and move it to the two sides of the pit to feed the mash to the sides of the pit. During this process, the scraping mechanism can scrape the mash in the two grabs to reduce the residue of mash in the grabs. This allows the two grabs to feed the mash without opening the angle too wide, reducing the spillage of granular raw materials caused by the angle opening too wide.

[0016] Optionally, the scraping mechanism includes a scraper, a drive assembly, a reversing assembly, and a cutting assembly. The scraper is slidably installed inside the grab bucket, and the end of the scraper can slide along the inner wall of the grab bucket. When the two grab buckets are opened, the drive assembly can drive the scraper to move closer to the center of the two grab buckets. When the two scraper buckets are opened at a certain angle, the reversing assembly can drive the scraper to move away from the center of the two grab buckets. The cutting assembly can cut off the power of the drive assembly when the two grab buckets rotate in the closing direction, so that the scraper will not move with the closing of the two grab buckets.

[0017] By adopting the above technical solution, when it is necessary to feed the mash in the grab bucket, the two grab buckets are controlled to gradually open. At this time, the mash located at the contact position of the two grab buckets will be gradually fed into the pit. During this process, the drive component drives the scraper in the two grab buckets to move towards each other, and finally moves to the position where they are close to each other, that is, the edge of each grab bucket, so as to push the mash in each grab bucket out of the two grab buckets, thereby realizing the feeding of mash in the grab buckets;

[0018] When it is necessary to grab the mash, first control the two grabs to open. At this time, the drive component will control the two scrapers to move towards each other. Continue to control the two grabs to open. When the angle between the two grabs reaches a certain value, the reversing component will drive the two scrapers to move away from each other, so that the scrapers move from the material feeding edge that is close to each other inside the grab to the material feeding edge that is far away from the grab. At this time, the scrapers will not affect the grab operation of the grab.

[0019] When the two grab buckets grab the mash, the ends of the two grab buckets that are far apart rotate towards each other. At this time, the cutting component will cut off the linkage between the drive component and the scraper. The drive component will not drive the scraper to move, so that the grab buckets can grab the mash normally, and the scraper will not affect the grab buckets' grabbing action.

[0020] Optionally, the drive assembly includes an arc-shaped rack, a driven gear, a linkage, and a drive wheel. The arc-shaped rack is slidably mounted on the side wall of the grab bucket. The two ends of the scraper are respectively fixedly connected to the sides of the two arc-shaped racks. The driven gear is rotatably mounted on the side wall of the grab bucket and meshes with the arc-shaped rack. The drive wheel is rotatably mounted on the side wall of the grab bucket and is drively connected to the rotating shaft of the grab bucket. The linkage is used to drively connect the drive wheel and the driven gear. The reversing assembly is used to drively connect the rotating shaft of the grab bucket and drive the drive wheel to reciprocate.

[0021] By adopting the above technical solution, when the two grabs open, the reversing component drives the drive wheel to rotate in one direction first, and drives the connecting gear to rotate through the connecting component, so that the two sets of arc racks slide in the direction of approaching each other, so that the two sets of arc racks drive the corresponding scraper to move, thereby realizing the movement of the two scraper plates in the direction of approaching each other.

[0022] As the two grabs continue to open, the reversing assembly drives the drive wheel to rotate in the opposite direction, which in turn drives the connecting gear to rotate through the linkage. This causes the two sets of arc-shaped racks to slide in a direction away from each other, so that the two sets of arc-shaped racks drive the corresponding scraper to move, thus realizing the movement of the two scraper plates in a direction away from each other.

[0023] Optionally, the reversing assembly includes a first drive wheel, a second drive wheel, and a lever. The first drive wheel is rotatably mounted on the side wall of the mounting base, and the second drive wheel is rotatably mounted on the side wall of the grab bucket. The first drive wheel is coaxially arranged with the rotation axis of the grab bucket, and the first drive wheel and the second drive wheel mesh.

[0024] The levers are provided in multiple ways, and each lever is spaced apart on the wheel surface of the first drive wheel and the second drive wheel. Each lever can be inserted into the wheel surface gap of the drive wheel to drive the drive wheel to reciprocate. The cutting component is used to cut off the power on the grab bucket rotating shaft according to the rotation direction of the first drive wheel.

[0025] By adopting the above technical solution, when the two grabs open, the grabs drive the second drive wheel to rotate. When the second drive wheel rotates, it will drive the lever to rotate. At the same time, the second drive wheel will drive the first drive wheel to rotate in the opposite direction. The multiple levers on the second drive wheel will mesh with the wheel surface gap of the drive wheel in sequence, thereby driving the drive wheel to rotate in one direction, and finally causing the scraper to move towards each other.

[0026] As the opening angle of the two grabs increases, the multiple levers on the second drive wheel rotate until they are no longer engaged with the clearance between the drive wheel and the drive wheel. At this time, the multiple levers on the first drive wheel will drive the drive wheel to rotate. Since the first drive wheel is engaged 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 drive wheel to rotate in the opposite direction through the multiple levers, ultimately causing the scraper to move in a direction away from each other.

[0027] Optionally, the cutting assembly includes an internal gear ring, a rotating shaft, a locking rod, and an elastic element. The first drive wheel is rotatably mounted on the rotating shaft of the grab bucket, and the internal gear ring is disposed on the inner peripheral wall of the first drive 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 internal gear ring during rotation. The elastic element is used to drive the end of the locking rod away from the rotating shaft away from the rotating shaft of the grab bucket.

[0028] As the grab bucket gradually opens, the rotating shaft of the grab bucket drives the locking rod to insert into the internal gear ring and lock the internal gear ring, thus fixing the first drive wheel and the rotating shaft of the grab bucket in place. As the grab bucket gradually closes, the rotating shaft of the grab bucket drives the locking rod to disengage from the tooth surface of the internal gear ring, thus movably connecting the first drive wheel and the rotating shaft of the grab bucket.

[0029] 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.

[0030] Optionally, a telescopic mechanism is provided between the scraper and the arc-shaped rack for driving the scraper to elastically abut against the inner wall of the grab bucket.

[0031] By adopting the above technical solution, the telescopic mechanism enables the end of the scraper to elastically abut against the inner wall of the grab bucket, thereby allowing the scraper to more thoroughly clean the mash in the grab bucket during the scraping process, without easily damaging the inner wall of the grab bucket.

[0032] Optionally, the telescopic mechanism includes a mounting plate and a tension spring. One end of the mounting plate is fixed to the side of the arc-shaped rack, and the other end has an opening groove for slidingly inserting the scraper. The tension spring is installed in the opening groove to allow the end of the scraper away from the mounting plate to extend out of the opening groove and elastically abut against the inner wall of the grab bucket.

[0033] By adopting the above technical solution, when the scraper moves along the inner wall of the grab bucket to scrape, the tension spring causes the end of the scraper to elastically abut against the inner wall of the grab bucket, so that the scraper can scrape the mash in the grab bucket more thoroughly and will not damage the inner wall of the grab bucket.

[0034] Optionally, a pressing plate and a pressing mechanism are installed at the middle position inside the two grabs to press and squeeze out the mash between the two grabs when the two grabs are opened.

[0035] By adopting the above technical solution, when the two grab buckets open to discharge material, the pressing mechanism drives the pressing plate to move downwards, thereby pressing the mash inside the two grab buckets and accelerating the discharge speed. When the two grab buckets open to grab the mash, although the pressing plate moves downwards, when the two grab buckets close together, the pressing mechanism drives the pressing plate to move upwards, which does not affect the normal grabbing of the mash by the grab buckets.

[0036] Optionally, the pressing mechanism includes a connector and a double-sided rack that is slidably engaged in the connector. The connector is mounted on the side wall of the mounting base. The double-sided rack meshes with the two first drive wheels respectively. The end of the double-sided rack away from the connector is fixedly connected to the pressing plate.

[0037] By adopting the above technical solution, when the two grabs open, the first drive wheel drives the double-sided rack to move downward, thereby driving the pressing plate to press down and realize the feeding of the mash. When the two grabs close, the first drive wheel drives the double-sided rack to move downward, thereby driving the pressing plate to move upward.

[0038] This application also provides a method for conveying raw materials into the fermentation pit based on a double-bottom brewing process, including the following steps:

[0039] S1: The opening and closing mechanism on the conveying trolley clamps and transfers the mash, moving it from the pile of materials to the top of the corresponding fermentation pit;

[0040] S2: Control the two grabs on the conveying trolley to open and feed the mash in the two grabs into the fermentation pit. Repeatedly clamp and transfer the mash in the fermentation pit to the required amount.

[0041] S3: Control the two grab buckets to open and grab the mash in the fermentation pit. Control the conveyor trolley to move the two grab buckets to the edge of the fermentation pit, so that the middle position of the two grab buckets is close to the sunken position in the fermentation pit.

[0042] S4: Control the two grab buckets to open, so that the mash in the middle of the two grab buckets fills the sunken position on the side of the pit. During the opening of the two grab buckets, the scraping mechanism set in the two grab buckets will automatically complete the scraping of the mash in the corresponding grab bucket as the corresponding grab bucket gradually opens, and repeatedly fill the sunken position in the pit until the mash in the pit is leveled.

[0043] S5: Control the closure of the two grab buckets, and continuously change the horizontal and vertical positions of the two grab buckets through the conveying trolley, so that the bottom of the two grab buckets continuously presses and flattens the surface of the mash in the fermentation pit until the surface of the mash in the fermentation pit is flat.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] 1. When it is necessary to feed the mash in the grab bucket, control the two grab buckets to gradually open. At this time, the mash located at the contact position of the two grab buckets will be gradually fed into the fermentation pit. During this process, the drive component drives the scraper in the two grab buckets to move towards each other, and finally move to the position where they are close to each other, that is, the edge of each grab bucket, so as to push the mash in each grab bucket out of the two grab buckets, thus realizing the feeding of mash in the grab buckets;

[0046] When it is necessary to grab the mash, first control the two grabs to open. At this time, the drive component will control the two scrapers to move towards each other. Continue to control the two grabs to open. When the angle between the two grabs reaches a certain value, the reversing component will drive the two scrapers to move away from each other, so that the scrapers move from the material feeding edge that is close to each other inside the grab to the material feeding edge that is far away from the grab. At this time, the scrapers will not affect the grab operation of the grab.

[0047] When the two grabs grab the mash, the ends of the two grabs that are far apart rotate towards each other. At this time, the cutting component will cut off the linkage between the drive component and the scraper. The drive component will not drive the scraper to move, so that the grabs can grab the mash normally and the scraper will not affect the grab action of the grabs.

[0048] 2. The scraping mechanism in this application can complete the scraping of mash in the grab bucket. Compared with using ordinary power components to drive the scraper to scrape the mash in the grab bucket, this structure is more suitable for scraping mash with granular raw materials. Ordinary power components are easily damaged in the grab bucket full of granular raw materials.

[0049] 3. The scraping mechanism and pressing mechanism in this application can complete all actions while the two grabs are rotating, reducing the additional input of external power sources and greatly saving energy.

[0050] 4. The telescopic mechanism allows the end of the scraper to elastically abut against the inner wall of the grab bucket, thereby enabling the scraper to more thoroughly clean the mash in the grab bucket during the scraping process, without easily damaging the inner wall of the grab bucket.

[0051] 5. During the process of the two grab buckets opening to discharge material, the pressing mechanism will drive the pressing plate to move downward, thereby pressing the mash in the two grab buckets and speeding up the discharge speed; when the two grab buckets open to grab the mash, although the pressing plate will move downward, when the two grab buckets close 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 buckets.

Detailed Implementation

[0062] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail below.

[0063] This application discloses a raw material feeding and conveying system based on a double-bottom brewing process, referring to... Figure 1 , Figure 2 and Figure 3 It includes a track 1, a conveying trolley 11, and two grab buckets 12 installed below the conveying trolley 11. The outer walls of the two grab buckets 12 are equipped with leveling rollers 121 for leveling. The conveying trolley 11 is equipped with an opening and closing mechanism 2 for controlling the opening and closing of the two grab buckets 12. The two grab buckets 12 are equipped with a scraping mechanism 3 for scraping the raw materials inside the grab buckets 12 as the two grab buckets 12 gradually open.

[0064] 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 component 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 component 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.

[0065] When it is necessary to transfer the mash to the corresponding fermentation pit, control the conveyor trolley 11 to move directly above the fermentation pit, and then control the grab bucket 12 to descend to one end of the fermentation pit. At this time, the telescopic component 23 extends, and the telescopic component 23 drives the sliding seat 22 to move downward. The sliding seat 22 drives the connecting rod 24 to rotate, so that the lower end of the grab bucket 12 opens in a direction away from each other, realizing the feeding of mash into the two grab buckets 12.

[0066] During the feeding process, the conveyor trolley 11 drives the two grab buckets 12 to move along the length of the fermentation pit, thereby achieving uniform feeding of the mash in the fermentation pit. During this process, the two leveling rollers 121 will spread and level the mash fed into the fermentation pit, making the mash in the fermentation pit more uniform, so as to ensure the fermentation effect of the mash in the fermentation pit.

[0067] During this process, the scraping mechanism 3 can scrape the mash inside the two grab buckets 12 when the two grab buckets 12 open to discharge the material, thereby reducing the residue of the mash inside the grab buckets 12 and enabling the two grab buckets 12 to discharge the material without opening the angle too large.

[0068] After the mash in the fermentation pit is fed and initially spread, the mash in the middle of the pit needs to be grabbed and moved to the two sides of the pit so that the lower areas on both sides of the pit are also filled with an equal amount of mash. At this time, the two grab buckets 12 grab the mash in the middle and move it to the two sides of the pit to feed the mash to the areas on the sides of the pit. During this process, the scraping mechanism 3 can scrape the mash in the two grab buckets 12 to reduce the residue of mash in the grab buckets 12, so that the two grab buckets 12 do not need to open a large angle to feed the mash, reducing the spillage of granular raw materials caused by excessive angle opening.

[0069] Reference Figure 4 , Figure 5 and Figure 6 The scraping mechanism 3 includes a scraper 31, a drive assembly 32, a reversing assembly 33, and a cutting assembly 34. The scraper 31 is slidably installed inside the grab bucket 12, and the end of the scraper 31 can slide along the inner wall of the grab bucket 12. When the two grab buckets 12 are opened, the drive assembly 32 can drive the scraper 31 to move closer to the middle position of the two grab buckets 12. When the two scraper 31 are opened at a certain angle, the reversing assembly 33 can drive the scraper 31 to move away from the middle position of the two grab buckets 12. The cutting assembly 34 can cut off the power of the drive assembly 32 when the two grab buckets 12 rotate in the closing direction, so that the scraper 31 will not move with the closing of the two grab buckets 12.

[0070] When it is necessary to discharge the mash in the grab bucket 12, the two grab buckets 12 are controlled to gradually open. At this time, the mash located at the contact position of the two grab buckets 12 will be gradually discharged into the fermentation pit. During this process, the drive component 32 drives the scraper 31 in the two grab buckets 12 to move towards each other, and finally moves to the position where they are close to each other, that is, the edge of each grab bucket 12, so as to push the mash in each grab bucket 12 out of the two grab buckets 12, thereby realizing the discharge of mash in the grab bucket 12.

[0071] When it is necessary to grab the mash, first control the two grab buckets 12 to open. At this time, the drive component 32 will control the two scraper plates 31 to move towards each other. Continue 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 will drive the two scraper plates 31 to move away from each other, so that the scraper plates 31 move from the material feeding edge that is close to each other in the grab bucket 12 to the material feeding edge that is far away from the grab bucket 12. At this time, the scraper plates 31 will not affect the grabbing operation of the grab bucket 12.

[0072] When the two grab buckets 12 grab the mash, the ends of the two grab buckets 12 that are far apart rotate toward each other. At this time, the cutting component 34 cuts off the linkage between the drive component 32 and the scraper 31. At this time, the drive component 32 will not drive the scraper 31 to move, so that the grab buckets 12 can grab the mash normally, and the scraper 31 will not affect the grab buckets 12's grab bucket ...

[0073] Reference Figure 5 , Figure 6 and Figure 7 The drive assembly 32 includes an arc-shaped rack 321, a driven gear 322, a connecting member 323, and a drive 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 fixedly connected to the sides of the two arc-shaped racks 321 respectively. 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 drive wheel 324 is rotatably mounted on the side wall of the grab bucket 12 and is connected to the rotating shaft of the grab bucket 12. The connecting member 323 is used to drive the drive wheel 324 and the driven gear 322. The connecting member 323 adopts a belt drive. The reversing assembly 33 is used to drive the rotating shaft of the grab bucket 12 and drive the drive wheel 324 to reciprocate.

[0074] When the two grabs 12 open, the reversing component 33 drives the drive wheel 324 to rotate in one direction first, and drives the connecting gear to rotate through the connecting member 323, so that the two sets of arc racks 321 slide towards each other, so that the two sets of arc racks 321 drive the corresponding scraper 31 to move, thus realizing that the two scraper 31 move towards each other.

[0075] As the two grabs 12 continue to open, the reversing assembly 33 will drive the drive wheel 324 to rotate in the opposite direction, which will drive the connecting gear to rotate through the linkage 323, thereby causing the two sets of arc racks 321 to slide in a direction away from each other, so that the two sets of arc racks 321 will drive the corresponding scraper 31 to move, thus realizing that the two scraper 31 move in a direction away from each other.

[0076] Reference Figure 5 , Figure 6 and Figure 7 The reversing assembly 33 includes a first drive wheel 331, a second drive wheel 332, and a lever 333. The first drive wheel 331 is rotatably mounted on the side wall of the mounting base 21, and the second drive wheel 332 is rotatably mounted on the side wall of the grab bucket 12. The first drive wheel 331 is coaxially fixed with the rotation shaft of the grab bucket 12, and the first drive wheel 331 and the second drive wheel 332 mesh.

[0077] Multiple levers 333 are provided, and each lever 333 is spaced apart on the wheel surface of the first drive wheel 331 and the second drive wheel 332. Each lever 333 can be inserted into the wheel surface gap of the drive wheel 324 to drive the drive 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 drive wheel 331.

[0078] When the two grabs 12 open, the grabs 12 drive the second drive wheel 332 to rotate. When the second drive wheel 332 rotates, it will drive the lever 333 to rotate. At the same time, the second drive wheel 332 will drive the first drive wheel 331 to rotate in the opposite direction. The multiple levers 333 on the second drive wheel 332 will engage with the wheel surface gap of the drive wheel 324 in sequence, thereby driving the drive wheel 324 to rotate in one direction, and finally causing the scraper 31 to move towards each other.

[0079] As the opening angle of the two grabs 12 increases, the multiple levers 333 on the second drive wheel 332 rotate until they are no longer engaged with the wheel surface clearance of the drive wheel 324. At this time, the multiple levers 333 on the first drive wheel 331 will drive the drive wheel 324 to rotate. Since the first drive wheel 331 is engaged with the second drive wheel 332, the rotation direction of the first drive wheel 331 is opposite to the rotation direction of the second drive wheel 332. At this time, the first drive wheel 331 drives the drive wheel 324 to rotate in the opposite direction through the multiple levers 333, which ultimately causes the scraper 31 to move in a direction away from each other.

[0080] Reference Figure 6 , Figure 7 and Figure 8The cutting assembly 34 includes an internal gear ring 341, a rotating shaft 342, a locking rod 343, and an elastic element 344. The first drive wheel 331 is rotatably sleeved on the rotating shaft of the grab bucket 12, and the internal gear ring 341 is disposed on the inner peripheral wall of the first drive 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 mounted on the rotating shaft 342 and can extend into the tooth surface of the internal gear ring 341 during rotation. The elastic element 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.

[0081] As 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. As 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.

[0082] A telescopic mechanism 4 is provided between the scraper 31 and the arc-shaped rack 321 to drive the scraper 31 to elastically abut against the inner wall of the grab bucket 12. (See reference) Figure 5 and Figure 6 The telescopic mechanism 4 includes a mounting plate 41 and a tension spring. One end of the mounting plate 41 is fixed to the side of the arc-shaped rack 321, and the other end has an opening groove for slidingly inserting the scraper 31. The tension spring is installed in the opening groove to allow the end of the scraper 31 away from the mounting plate 41 to extend out of the opening groove and elastically abut against the inner wall of the grab bucket 12.

[0083] When the scraper 31 moves along the inner wall of the grab bucket 12 to scrape, the tension spring causes the end of the scraper 31 to elastically abut against the inner wall of the grab bucket 12, so that the scraper 31 scrapes the mash in the grab bucket 12 more thoroughly and does not damage the inner wall of the grab bucket 12.

[0084] A pressing plate and a pressing mechanism 5 are installed in the middle of the two grab buckets 12, which are used to press and squeeze the mash between the two grab buckets 12 when the two grab buckets 12 are opened. (Refer to...) Figure 5 , Figure 6 and Figure 7 The pressing mechanism 5 includes a plug seat 51 and a double-sided rack 52 that is slidably engaged in the plug seat 51. The plug seat 51 is installed on the side wall of the mounting base 21. The double-sided rack 52 is engaged with two first drive wheels 331 respectively. The end of the double-sided rack 52 away from the plug seat 51 is fixedly connected to the pressing plate.

[0085] As the two grab buckets 12 open to discharge the mash, the pressing mechanism 5 moves the pressing plate downwards, thus pressing the mash inside the two grab buckets 12 and accelerating the discharge speed. While the pressing plate moves downwards when the two grab buckets 12 are opening to grab the mash, the pressing mechanism 5 moves the pressing plate upwards when the two grab buckets 12 close, ensuring that the normal grabbing of the mash by the grab buckets 12 is not affected.

[0086] Furthermore, in order to enable the leveling roller 121 to assist in leveling the mash in the fermentation pit during the opening and closing of the two grabs 12, a linkage mechanism 6 is provided at the end of the connecting rod 24 away from the mounting base 21 and at 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 to the shaft of the connecting rod 24, and the second linkage wheel 63 is coaxially fixed to the end of the leveling roller 121. The linkage belt 62 is connected to the first linkage wheel 61 and the second linkage wheel 63 respectively. The diameter of the first linkage wheel 61 is much larger than the diameter of the second linkage wheel 63. In this embodiment, the diameter of the first linkage wheel 61 is four times the diameter of the second linkage wheel 63.

[0087] During the opening or closing of the two grabs 12, the first connecting wheel 61 can drive the second connecting wheel 63 to rotate via the connecting belt 62. Since the diameter of the first connecting wheel 61 is much larger than the diameter of the second connecting wheel 63, the first connecting wheel 61 can drive the second connecting wheel 63 to rotate at a larger angle or a greater number of rotations with a smaller rotation angle.

[0088] When the two grab buckets 12 open, they are in the stage of waiting to be grabbed or feeding. If they are in the stage of waiting to be grabbed, the leveling roller 121 will push the mash to both sides of the pit to help fill the gaps that need to be filled on both sides. When the two grab buckets 12 close, they are in the stage of feeding. At this time, the leveling roller 121 will push the mash to the middle of the pit, that is, to the feeding position of the two grab buckets 12, so as to adjust and fill the low-lying areas formed by the grabs of the two grab buckets 12, making it easier for the two grab buckets 12 to grab the mash again.

[0089] The implementation principle of the raw material feeding and conveying system based on the double-bottom brewing process in this application embodiment is as follows: When it is necessary to transfer the mash to the corresponding fermentation pit, the conveying trolley 11 is controlled to move directly above the fermentation pit, and then the grab bucket 12 is controlled to descend to one end inside the fermentation pit. At this time, the telescopic member 23 extends, and the telescopic member 23 drives the sliding seat 22 to move downward. The sliding seat 22 drives the connecting rod 24 to rotate, so that the lower end of the grab bucket 12 opens in a direction away from each other, so as to realize the feeding of mash into the two grab buckets 12.

[0090] During the feeding process, the conveyor trolley 11 drives the two grab buckets 12 to move along the length of the fermentation pit, thereby achieving uniform feeding of the mash in the fermentation pit. During this process, the two leveling rollers 121 will spread and level the mash fed into the fermentation pit, making the mash in the fermentation pit more uniform, so as to ensure the fermentation effect of the mash in the fermentation pit.

[0091] During this process, the scraping mechanism 3 can scrape the mash inside the two grab buckets 12 when the two grab buckets 12 open to discharge the material, thereby reducing the residue of the mash inside the grab buckets 12 and enabling the two grab buckets 12 to discharge the material without opening the angle too large.

[0092] After the mash in the fermentation pit is fed and initially spread, the mash in the middle of the pit needs to be grabbed and moved to the two sides of the pit so that the lower areas on both sides of the pit are also filled with an equal amount of mash. At this time, the two grab buckets 12 grab the mash in the middle and move it to the two sides of the pit to feed the mash to the areas on the sides of the pit. During this process, the scraping mechanism 3 can scrape the mash in the two grab buckets 12 to reduce the residue of mash in the grab buckets 12, so that the two grab buckets 12 do not need to open a large angle to feed the mash, reducing the spillage of granular raw materials caused by excessive angle opening.

[0093] This application also discloses a method for conveying raw materials into the fermentation pit based on a double-bottom brewing process. The method uses the aforementioned raw material conveying system based on the double-bottom brewing process and includes the following steps:

[0094] S1: The opening and closing mechanism 2 on the conveying trolley 11 clamps and transfers the mash, moving it from the pile of materials to the top of the corresponding fermentation pit;

[0095] S2: Control the two grabs 12 on the conveying trolley 11 to open and feed the mash in the two grabs 12 into the fermentation pit. Repeatedly clamp and transfer the mash in the fermentation pit to the required amount.

[0096] S3: Control the two grab buckets 12 to open and grab the mash in the fermentation pit. Control the conveying trolley 11 to move the two grab buckets 12 to the edge of the fermentation pit, so that the middle position of the two grab buckets 12 is close to the sunken position in the fermentation pit.

[0097] S4: Control the two grab buckets 12 to open, so that the mash in the middle of the two grab buckets 12 fills the sunken position on the side of the pit. During the opening of the two grab buckets 12, the scraping mechanism 3 set in the two grab buckets 12 will automatically complete the scraping of the mash in the corresponding grab bucket 12 as the corresponding grab bucket 12 gradually opens, and repeatedly fill the sunken position in the pit until the mash in the pit is leveled.

[0098] 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 bottom of the two grab buckets 12 continuously presses and flattens the surface of the mash in the fermentation pit until the surface of the mash in the fermentation pit is flat.

[0099] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
