Description

Technical Field

[0001] This utility model belongs to the technical field of brewing process equipment, specifically relating to a chain plate tunnel storage machine. Background Technology

[0002] In brewing, rice husks are a crucial auxiliary fermentation material and filler, diluting starch and alcohol concentrations and improving starch utilization. The quality of the brewed liquor is directly affected by the use of rice husks. Normally, rice husks need to be steamed, spread out, and dried before use, and then stored for later use. However, during fermentation, the stored rice husks need to be transferred to the cellar using transport vehicles. This method is inflexible, time-consuming, and labor-intensive. Furthermore, because the rice husks tend to clump together after storage, the clumps need to be broken up before being placed in the cellar, further reducing efficiency and limiting production capacity. A solution to this problem is urgently needed. Utility Model Content

[0003] This utility model provides a chain plate tunnel storage machine, which aims to improve the convenience of storing and using rice husks and enhance operational efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a chain plate tunnel storage machine, comprising:

[0005] The frame is used to fix and support the machine on the ground. The frame is equipped with a horizontally extending tunnel storage bin. The top of one end of the tunnel storage bin has a feed inlet and the bottom of the other end has a discharge outlet.

[0006] The chain conveyor mechanism is horizontally arranged on the frame and forms the bottom of the tunnel storage bin. The chain conveyor mechanism is used to receive the material falling from the feed port and convey the material to the discharge port.

[0007] Multiple feeding rollers are distributed vertically and vertically in the tunnel storage bin and are all located on the side above the discharge port. Both ends of each feeding roller are rotatably connected to the bin wall of the tunnel storage bin.

[0008] Each of the feeding rollers is used to jointly block the material on the chain conveyor mechanism in a static state, and to break up and feed the material to the discharge port in a rotating dynamic state.

[0009] In one possible implementation, a first rotary drive is connected to one side wall of the tunnel storage bin, one end of a feeding roller extends out of the tunnel storage bin and is connected to the output end of the first rotary drive; the end of each feeding roller away from the first rotary drive extends out of the tunnel storage bin and is fitted with a sprocket, and adjacent sprockets are connected by chain drive.

[0010] In some embodiments, adjusting seats are horizontally slidably connected to both sides of the tunnel storage bin, each adjusting seat is provided with a bearing seat, the two ends of each feeding roller are respectively connected to one of the bearing seats, and the first rotary drive component is fixedly connected to one of the adjusting seats.

[0011] In some embodiments, a material level sensor is installed inside the tunnel storage chamber, and a vent pipe is installed on the top wall of the tunnel storage chamber directly above the discharge port.

[0012] For example, the feeding roller has multiple sets of feeding rods spaced apart along its axial direction, and each set of feeding rods includes multiple feeding rods spaced apart along the circumferential direction of the feeding roller.

[0013] For example, a chain conveyor mechanism includes:

[0014] The second rotary drive component is fixedly connected to the frame;

[0015] The drive shaft is rotatably connected to the frame and located above the discharge port. The drive shaft is connected to the output end of the second rotary drive unit. Drive wheels are respectively sleeved at both ends of the drive shaft.

[0016] The driven shaft is rotatably connected to the frame and located below the feed inlet. Driven wheels are respectively fitted at both ends of the driven shaft, and the two driven wheels correspond to the two driving wheels respectively.

[0017] Two roller drive chains are respectively fitted onto the corresponding driving and driven wheels to drive the driven shaft to rotate synchronously with the driving shaft. Several load-bearing chain plates are connected between the two roller drive chains. Each load-bearing chain plate is sequentially hinged along the rotation trajectory of the roller drive chains to form the bottom of the tunnel storage bin.

[0018] In one possible implementation, two chain tracks are fixedly connected to the frame, with the two chain tracks located between corresponding driving and driven wheels, respectively. The chain tracks are flush with the upper rim of the driving wheel to support the roller drive chain.

[0019] For example, at least one intermediate beam is fixedly connected to the frame, the intermediate beam is located between two chain track, and rollers are rotatably connected to the connecting shaft of adjacent load-bearing chain plates, the rollers rolling on the intermediate beam.

[0020] For example, both the drive shaft and the driven shaft are equipped with a disc corresponding to the position of each intermediate beam, and the edge of the disc has grooves distributed circumferentially to accommodate the rollers.

[0021] In some embodiments, the frame is provided with two receiving slots, which are located below the two ends of the chain conveyor mechanism respectively; the frame is also provided with a feed scraper and a discharge scraper, the feed scraper is located below the feed inlet and slides against the upper surface of the chain conveyor mechanism, and the discharge scraper is located above the discharge outlet and slides against the lower surface of the chain conveyor mechanism.

[0022] The beneficial effects of the chain plate tunnel storage machine provided by this utility model are as follows: Compared with the prior art, the chain plate tunnel storage machine of this utility model has dual functions of conveying and storage. The steamed and cooled rice husk material can fall directly from the inlet into the chain plate conveying mechanism in the tunnel storage bin. It is continuously conveyed towards the outlet by the chain plate conveying mechanism, and the various material-pulling rollers form a baffle above the outlet until the material fills the entire tunnel storage bin, thereby realizing the storage of material. When the fermentation process requires the addition of rice husk material, the material can be pushed into the outlet by rotating the various material-pulling rollers. The rotation of the material-pulling rollers can also evenly disperse the material and eliminate lumps, so that the material discharged from the outlet can be directly used in the cellar. This not only saves the process of material entering and leaving the storage bin, but also eliminates the process of additional dispersion of material before use. This greatly improves the convenience of storing and using rice husk material, which is conducive to improving the efficiency and capacity of the brewing process production line.

In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0030] Please refer to the following: Figures 1 to 4The chain plate tunnel storage machine provided by this utility model will now be described. The chain plate tunnel storage machine includes a frame 10, a chain plate conveying mechanism 30, and multiple material-pushing rollers 40. The frame 10 is fixedly supported on the ground, and a horizontally extending tunnel storage bin 20 is provided on the frame 10. One end of the tunnel storage bin 20 has a feed inlet 201 at the top, and the other end has a discharge outlet 202 at the bottom. The chain plate conveying mechanism 30 is horizontally arranged on the frame 10 and forms the bottom of the tunnel storage bin 20. The chain plate conveying mechanism 30 is used to receive the material falling from the feed inlet 201 and convey the material to the discharge outlet 202. Multiple material-pushing rollers 40 are distributed vertically at intervals in the tunnel storage bin 20 and are all located above the side of the discharge outlet 202. Both ends of each material-pushing roller 40 are rotatably connected to the bin wall of the tunnel storage bin 20. The material-pushing rollers 40 are used to jointly block the material on the chain plate conveying mechanism 30 in a static state and to disperse and push the material to the discharge outlet 202 in a rotating dynamic state.

[0031] It should be noted that in this embodiment, wall panels are provided on both sides and the top of the frame 10, thereby forming a horizontally extending tunnel storage silo 20 in conjunction with the upper surface of the chain conveyor mechanism 30. Rice husk material can directly fall onto the chain conveyor mechanism 30 through the feed inlet 201. It should be understood that there are two possible application methods here. One is that the chain conveyor mechanism 30 continuously operates during the feeding process, thereby causing the material to be evenly spread on the surface of the chain conveyor mechanism 30. This allows the rice husks to be directly fed into the chain conveyor mechanism 30 after steaming, spreading evenly and cooling down as they travel from the feed inlet 201 to the discharge outlet 202. One method involves directly discharging the material through the outlet 202 into the storage pit. Another method involves the chain conveyor 30 continuously conveying the material to the outlet 202 during the feeding process, while the material-pushing rollers 40 remain stationary. This allows the material to be blocked in front of the outlet 202 by the various material-pushing rollers 40, thus storing the material in the tunnel storage silo 20. When the material is needed, the material-pushing rollers 40 are activated to push the material to the outlet 202. Considering that the material may be compressed and agglomerated during storage, the rotation of the material-pushing rollers 40 can also break up the agglomerates, ensuring that the material discharged from the outlet 202 can be used directly.

[0032] The chain plate tunnel storage machine provided in this embodiment has both conveying and storage functions compared with the prior art. The steamed and cooled rice husk material can fall directly from the inlet 201 onto the chain plate conveyor 30 in the tunnel storage silo 20. The chain plate conveyor 30 continuously conveys the material towards the outlet 202, and each material-pushing roller 40 forms a baffle above and to the side of the outlet 202 until the material fills the entire tunnel storage silo 20, thus realizing the storage of the material. When the fermentation process requires the addition of rice husk material, the material can be pushed into the outlet 202 by rotating each material-pushing roller 40. The rotation of the material-pushing roller 40 can also evenly disperse the material and eliminate lumps, so that the material discharged from the outlet 202 can be directly used in the cellar. This not only saves the process of material entering and leaving the storage, but also eliminates the process of additional dispersion before the material is used. This greatly improves the convenience of storing and using rice husk material, which is conducive to improving the efficiency and capacity of the brewing process production line.

[0033] In some embodiments, see Figure 4 A first rotary drive 50 is connected to one side wall of the tunnel storage 20. One end of a feeding roller 40 extends out of the tunnel storage 20 and is connected to the output end of the first rotary drive 50. The end of each feeding roller 40 away from the first rotary drive 50 extends out of the tunnel storage 20 and is fitted with a sprocket 41. Adjacent sprockets 41 are connected by a chain 42.

[0034] The first rotary drive component 50 can be a motor, which directly drives one of the feeding rollers 40 to rotate. At the same time, the chain drive causes the feeding roller 40 to drive the remaining feeding rollers 40 to rotate in sequence, thereby realizing the synchronous rotation and stopping of each feeding roller 40. The structure is simple and the transmission is smooth.

[0035] For some possible implementations, please refer to [link / reference]. Figure 4 On both sides of the tunnel storage silo 20, there are horizontally sliding adjustment seats 21. Each adjustment seat 21 is equipped with a bearing seat 22. The two ends of each feeding roller 40 are respectively connected to one of the bearing seats 22, and the first rotary drive component 50 is fixedly connected to one of the adjustment seats 21. By adjusting the position of each adjustment seat 21, the tension of the chain 42 can be adjusted, and the relative position of each feeding roller 40 can be adjusted, thereby adjusting the amount of material being moved and the dispersing effect of the feeding roller 40, so as to meet the uniform discharge requirements of materials of different qualities and improve the flexibility of use.

[0036] It should be noted that, please refer to Figure 1The aforementioned tunnel storage silo 20 is equipped with a material level sensor 23, and a vent pipe 24 is installed on the top wall of the tunnel storage silo 20 directly above the discharge port 202. The material level sensor 23 allows for real-time monitoring of the material level within the tunnel storage silo 20. The vent pipe 24 serves two purposes: firstly, it prevents negative pressure from forming above the discharge port 202 during the discharge process, thus ensuring smooth material flow; secondly, it removes dust generated during the discharge process, improving environmental friendliness.

[0037] For example, such as Figure 1 As shown, the feeding roller 40 has multiple sets of feeding rods 43 spaced apart along its axial direction. Each set of feeding rods 43 includes multiple feeding rods 43 spaced apart circumferentially along the feeding roller 40. For rice husk materials required in the brewing process, clumping is likely to occur after steaming. The circumferentially and axially spaced feeding rods 43 can complete the feeding and dispersing action during rotation, allowing the material to be evenly distributed to the discharge port 202 for discharge. Simultaneously, when the feeding roller 40 is stationary, the feeding rods 43 can also form barriers around the material, allowing it to gradually accumulate from the discharge port 202 to the inlet 201 under the drive of the chain conveyor mechanism 30, thus realizing the storage function of the tunnel storage silo 20.

[0038] As one specific embodiment of the aforementioned chain conveyor mechanism 30, please refer to Figure 2 and Figure 4 The chain conveyor mechanism 30 includes a second rotary drive 31, a drive shaft 32, a driven shaft 33, and two roller drive chains 34. The second rotary drive 31 is fixedly connected to the frame 10. The drive shaft 32 is rotatably connected to the frame 10 and located above the discharge port 202. The drive shaft 32 is drively connected to the output end of the second rotary drive 31, and drive wheels 321 are respectively sleeved at both ends of the drive shaft 32. The driven shaft 33 is rotatably connected to the frame 10 and located below the feed port 201. In the case of the driven shaft 33, driven wheels 331 are respectively fitted at both ends of the driven shaft 33, and the two driven wheels 331 correspond to the two driving wheels 321 respectively; two roller transmission chains 34 are respectively fitted on the corresponding driving wheels 321 and driven wheels 331, which are used to drive the driven shaft 33 to rotate synchronously with the driving shaft 32. Several load-bearing chain plates 35 are connected between the two roller transmission chains 34. Each load-bearing chain plate 35 is sequentially hinged along the rotation trajectory of the roller transmission chain 34 to form the bottom of the tunnel storage bin 20.

[0039] The second rotary drive component 31 can be a motor, and the roller drive chain 34 can be a drive chain with a large-diameter roller sleeve rotatably connected to the connecting shaft. The corresponding links of the two chains 42 are connected to a common load-bearing chain plate 35, which serves as the bottom of the tunnel storage bin 20. The second rotary drive component 31 can drive the drive wheel 321 and then drive the drive shaft 32 to rotate by gear or chain drive. At the same time, the two roller drive chains 34 drive the driven wheel 331 and then drive the driven shaft 33 to rotate. This enables each load-bearing chain plate 35 to form a rotary motion trajectory around the drive shaft 32 and the driven shaft 33 in sequence, so that the material is continuously transported from the feed port 201 to the discharge port 202, thereby realizing the function of mobile storage.

[0040] In some embodiments, please refer to Figure 2 and Figure 3 Two chain support tracks 11 are fixedly connected to the frame 10. The two chain support tracks 11 are located between the corresponding driving wheel 321 and driven wheel 331, respectively. The upper rim of the chain support track 11 is flush with the upper rim of the driving wheel 321 to support the roller drive chain 34. Since the tunnel storage bin 20 is relatively long, it is difficult to obtain sufficient load capacity by relying solely on the tension of the roller drive chain 34. Therefore, the chain support tracks 11 are set to support the roller drive chain 34, so that the roller drive chain 34 can bear only rotational tension as much as possible and not downward pressure. This can improve the smoothness of operation of the roller drive chain 34, reduce energy consumption, and also improve the load-bearing capacity of the load-bearing chain plate 35.

[0041] See here. Figure 3 The specific structure of the roller drive chain 34 is understood, with each link shaft fitted with a large-diameter roller sleeve for rolling the support chain track 11. The large-diameter roller sleeves rolling on the support chain track 11 provide upward support for the roller drive chain 34, improving load-bearing capacity while ensuring smooth operation.

[0042] To further improve load-bearing capacity, please refer to Figure 3 At least one intermediate beam 12 is fixedly connected to the frame 10. The intermediate beam 12 is located between two chain track 11. Rollers 351 are rotatably connected to the connecting shafts of adjacent load-bearing chain plates 35, and the rollers 351 roll on the intermediate beam 12. In order to ensure that the load-bearing chain plates 35 can smoothly move around the drive shaft 32 and the driven shaft 33, the adjacent load-bearing chain plates 35 are connected by hinges to each other. By setting rollers 351 at intervals on the connecting shafts and rolling them on the corresponding intermediate beams 12, the intermediate beams 12 support the middle of the load-bearing chain plates 35, which can prevent the load-bearing chain plates 35 from bending and deforming under the pressure of the material's weight.

[0043] To ensure transmission stability, such as Figure 3As shown, both the drive shaft 32 and the driven shaft 33 are equipped with a disc 36 corresponding to the position of each intermediate beam 12. The edge of the disc 36 has grooves 361 spaced along its circumference, suitable for the rollers 351 to be inserted sequentially. The disc 36 provides support for the load-bearing chain plate 35 in the middle of the drive shaft 32 and the driven shaft 33. At the same time, the interlocking structure between the grooves 361 and the rollers 351 allows the disc 36 to output traction force to the load-bearing chain plate 35, thereby ensuring the overall force balance of the load-bearing chain plate 35 and improving the transmission stability.

[0044] It should be noted that you should refer to [link / reference]. Figure 2 In some embodiments, the frame 10 is provided with two receiving slots 13, which are located below both ends of the chain conveyor mechanism 30 respectively; the frame 10 is also provided with a feeding scraper 14 and a discharging scraper 15, the feeding scraper 14 is located below the feeding port 201 and slides against the upper surface of the chain conveyor mechanism 30, and the discharging scraper 15 is located above the discharging port 202 and slides against the lower surface of the chain conveyor mechanism 30.

[0045] For the conveying surface of the chain conveyor mechanism 30, namely the load-bearing chain plate 35, when discharging material around the driven shaft 33, there may be situations where the adhered material cannot fall smoothly. Therefore, the discharge scraper 15 is provided to scrape the adhered material into the receiving trough 13. The function of the feed scraper 14 is, on the one hand, to perform secondary scraping on the surface of the chain conveyor mechanism 30, and on the other hand, to form a barrier on the side of the feed inlet 201 away from the discharge outlet 202, thereby ensuring that the material entering through the feed inlet 201 can fall onto the conveying surface of the chain conveyor mechanism 30, avoiding material spillage and waste.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
