Description

Technical Field

[0001] The utility model relates to the technical field of yeast culture storage, in particular to a yeast culture storage device. Background Art

[0002] Yeast culture refers to a microecological product formed by yeast on a specific fermentation substrate after sufficient anaerobic fermentation under specific process conditions. It is mainly composed of yeast extracellular metabolites, fermented substrates and yeast active substances. Yeast culture was first used as a feed raw material as a nutritional enhancer for ruminants. Yeast culture is mainly used in ruminant and livestock breeding, playing a dual role of nutrition and health care. After yeast culture production and processing, it needs to be stored.

[0003] The related technology (publication number: CN205556674U) discloses an automated yeast culture production line, which discloses a technical solution: conveying devices are arranged between the feeding device and the mixing device, between the mixing device and the fermentation device, and between the fermentation tank and the storage device, respectively; quantitative screw conveyors are arranged at the bottom of the feeding device; an integrated device integrating feeding, stirring and discharging is arranged in the fermentation tank; the production line has a high degree of mechanized operation, the output is greatly improved, and the intensity of manual labor is significantly reduced.

[0004] In the above-disclosed technical solution, it was found that the following problems exist in the related technology: after the yeast culture is produced and processed, it will be stored in a storage bin. During the storage process, the yeast culture is in a relatively static state, so that the solid yeast culture is accumulated inside. As the storage time increases, the friction and adhesion forces between the yeast culture particles will increase, making it difficult for the yeast culture to flow smoothly. The yeast culture accumulated at the outlet will not be discharged during discharge, which brings inconvenience to the use process. In this regard, we have proposed a new storage device for yeast culture.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include prior art information that does not constitute known to ordinary technicians in the field. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology. In order to solve the problem of yeast culture storage in the above-mentioned prior art, the utility model provides a storage device for yeast culture, which adopts a storage mechanism combined with a dispersed discharge structure to achieve the effect of facilitating discharge and avoiding blockage. The specific technical solution is as follows:

[0007] A storage device for yeast culture comprises a storage bin, wherein a bin cover is arranged on the top of the storage bin, a supporting hopper for supporting materials is embedded in the inner cavity of the storage bin, a material discharge hole is opened at the bottom of the supporting hopper, a material discharge outlet is rotatably arranged in the inner cavity of the material discharge hole, a material discharge hopper is rotatably arranged below the supporting hopper, a rotating support assembly for preventing material from escaping is arranged on the outer periphery of the material discharge hopper, and a discharge pipe is circumferentially arranged on the outer wall of the material discharge hopper.

[0008] In the above technical solution, the outer wall of the storage bin is provided with a linkage mechanism for driving the material discharge outlet member and the discharge hopper to rotate synchronously.

[0009] The linkage mechanism includes a gear rotatably arranged on the outer wall of the storage bin, a through groove is opened on the outer wall of the storage bin, an inner annular seat is sleeved on the outer wall of the discharge hopper, and teeth are evenly arranged on the outer wall of the inner annular seat in a circumferential direction. The gear penetrates the through groove and meshes with the teeth, a movable shaft is inserted into the inner cavity of the discharge hopper, and the unloading outlet piece is sleeved on the outside of the movable shaft.

[0010] A bulk material tray is rotatably arranged between the supporting hopper and the discharging hopper, and the bulk material tray is sleeved on the outside of the movable shaft, and the movable shaft passes through the inner cavity of the discharge hole.

[0011] The rotating support assembly comprises an outer annular seat embedded in the inner cavity of the storage bin, the outer annular seat is rotatably arranged outside the inner annular seat, and balls are circumferentially arranged between the inner annular seat and the outer annular seat.

[0012] An annular material guiding seat is fixedly mounted on the top of the outer annular seat, and the annular material guiding seat is embedded in the inner wall of the material storage bin.

[0013] The edge connection between the annular material guiding seat and the material discharging hopper is an arc edge.

[0014] A material separator is arranged circumferentially on the top of the bulk material tray.

[0015] A discharge port is arranged at the bottom of the storage bin, and a valve is arranged on the discharge port.

[0016] The discharge pipe is obliquely arranged between the outer wall of the discharge hopper and the inner wall of the storage bin.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the storage device for yeast culture:

[0018] 1. When it is necessary to take out the internal yeast culture, the yeast culture near the discharge hole is allowed to fall from the discharge hole in sequence as the auger blades rotate through the rotating discharge outlet, avoiding the accumulation of yeast culture near the discharge hole, thereby ensuring the smoothness of the discharge process.

[0019] 2. The yeast culture discharged from the discharge hole falls on the discharge hopper. The rotating discharge hopper allows the yeast culture in the hopper to be discharged to the outside through multiple circumferential discharge pipes. The rotating discharge hopper prevents the yeast culture from being retained on the bottom inner wall of the discharge hopper through centrifugal force, thereby avoiding waste.

[0020] 3. When discharging the yeast culture inside the storage bin, the teeth meshing with the gear drive the inner annular seat to rotate, so that the discharge hopper drives the discharge outlet located inside the discharge hole to rotate through the movable shaft, so that the discharge outlet rotates synchronously with the discharge hopper, which can ensure the discharge of the yeast culture flow while avoiding blockage in the discharge process, thereby ensuring the efficiency of the discharge process.

[0021] 4. The yeast culture discharged from the discharge hole falls on the rotating bulk disc. The centrifugal force formed by the bulk disc causes the yeast culture to scatter circumferentially onto the inner wall of the discharge hopper, avoiding the accumulation of directly fallen materials, thereby ensuring the smoothness of the yeast culture discharge process.

[0022] 5. During the rotation of the inner annular seat, the inner annular seat drives the slide groove to slide against the outer wall of multiple circumferential balls. At the same time, each ball slides on the inner wall of each movable groove respectively. The stability of the rotation process of the inner annular seat is ensured by the multiple circumferential balls, thereby ensuring the stability of the rotation process of the discharge hopper, and further ensuring the stability of the discharge process.

[0023] 6. In the process of the bulk disc driving the yeast culture that has fallen on the surface to scatter to the periphery, the material scattered to the outside of the discharge hopper falls from the storage bin onto the annular guide seat, and the material slides into the discharge hopper through the inclined surface of the annular guide seat. Then, the yeast culture is sent into the discharge port through the rotating discharge hopper, thereby preventing the yeast culture from being retained in the storage bin and causing waste.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The following is a combination of specific implementation cases and attached Figure 1-6 The present invention is further described below, but the present invention is not limited to these embodiments.

[0033] A storage device for yeast culture includes a storage bin 1, and a bin cover 2 is provided on the top of the storage bin 1. The bin cover 2 is put on the outside of the top of the storage bin 1, and then fixed on both sides of the bin cover 2 by bolts 14 to ensure the sealing of the storage bin 1 during the storage process. When loading, the bin cover 2 is removed by removing the bolts 14, making the operation process more convenient. The inner cavity of the storage bin 1 is embedded with a hopper 8 for supporting materials. The hopper 8 is fixedly embedded and installed inside the storage bin 1, and the circumferential edge of the hopper 8 is attached to the inner wall of the storage bin 1. The storage space is formed by the hopper 8 and the space of the storage bin 1 above.

[0034] A discharge hole 23 is provided at the bottom of the hopper 8. Since the hopper 8 is hopper-shaped, the stored yeast culture is discharged through the discharge hole 23 at the center of the bottom and falls on the bulk tray 6. The inner cavity of the discharge hole 23 is rotatably provided with a discharge outlet 22. The discharge outlet 22 can be an auger blade. When the discharge outlet 22 is stationary, it forms the bottom of the storage space with the hopper 8, so that the yeast culture is stored in the storage bin 1. When discharging the yeast culture, the discharge outlet 22 is attached to the inner wall of the discharge hole 23 and rotates continuously, so that the yeast culture near the discharge hole 23 rotates with the auger blade, so that the yeast culture falls from the discharge hole 23 in sequence.

[0035] A discharge hopper 3 is rotatably provided below the supporting hopper 8, and a rotating support assembly for preventing material from running away is provided on the outer periphery of the discharge hopper 3. The rotating support assembly 3 is sleeved on the outer periphery of the discharge hopper 3, so that the yeast culture falling from the discharge hole 23 falls on the discharge hopper 3. When the yeast culture splashes onto the inner wall of the storage bin 1, the yeast culture falls into the discharge hopper 3 through the inclined inner wall of the rotating support assembly. The outer wall of the discharge hopper 3 is provided with discharge pipes 17 in sequence in a circumferential direction, and the discharge pipes 17 are successively embedded and installed in a circle on the outer wall of the discharge hopper 3 near the bottom. The inclined fixture at one end of the discharge pipe 17 is embedded and installed on the outer wall of the discharge hopper 3 near the bottom, and the other end of the discharge pipe 17 is inclined toward the inner wall of the storage bin 1 near the bottom. When the yeast culture is discharged, it slides through the surroundings to the inside of the discharge port 10, and then the valve 11 on the discharge port 10 is opened to discharge the yeast culture to the outside.

[0036] The outer wall of the storage bin 1 is provided with a linkage mechanism that drives the material discharge outlet 22 to rotate synchronously with the discharge hopper 3. The linkage mechanism causes the material discharge outlet 22 and the discharge hopper 3 to rotate simultaneously. One end of four legs 18 is fixedly mounted on the outer wall of the storage bin 1, and a universal wheel 12 is mounted at the bottom of each leg 18. The four universal wheels 12 at the bottom make the movement of the storage bin 1 more convenient. After the yeast culture is put into the storage bin 1, the storage bin 1 is moved to a suitable storage position through the universal wheels 12 at the bottom. The top of the storage bin 1 is opened and closed by installing and removing the bolts 14, and the yeast culture is placed in the storage bin 1 for storage.

[0037] When the yeast culture inside needs to be taken out, the discharging hopper 3 and the discharge outlet 22 are rotated synchronously through the linkage mechanism, and the yeast culture near the discharge hole 23 is caused to fall from the discharge hole 23 in sequence as the auger blade rotates through the rotating discharge outlet 22. This prevents the yeast culture from accumulating near the discharge hole 23, thereby ensuring the smoothness of the discharge process.

[0038] The yeast culture discharged from the discharge hole 23 falls on the discharge hopper 3. The yeast culture in the hopper is discharged to the outside through multiple circumferential discharge pipes 17 by the rotating discharge hopper 3, so that multiple outlets respectively sprinkle the yeast culture onto the bucket-shaped inner wall near the bottom of the storage bin 1. Then, the discharge port 10 is opened by the valve 11 to collect and use the discharged yeast culture. The rotating discharge hopper 3 prevents the yeast culture from being retained on the bottom inner wall of the discharge hopper 3 by centrifugal force, thereby avoiding waste.

[0039] The linkage mechanism includes a gear 5 rotatably arranged on the outer wall of the storage bin 1. The motor 15 is fixed to the outer wall of the storage bin 1 through a motor seat, and the gear 5 is fixedly sleeved on the outside of the output shaft of the motor 15 through a mounting hole opened in the center, and the motor 15 is electrically connected to the external power supply through a wire. A through groove 13 is opened on the outer wall of the storage bin 1, and an inner ring seat 16 is sleeved on the outer wall of the discharge hopper 3. The outer wall of the inner ring seat 16 is evenly provided with teeth 19 in the circumferential direction, and the gear 5 is meshed with the teeth 19 after passing through the through groove 13. The inner ring seat 16 is fixedly sleeved on the outer wall of the discharge hopper 3 through the central mounting through hole, and a circle of teeth 19 is sequentially installed on the circumferential outer wall of the inner ring seat 16.

[0040] A through slot 13 communicating with the interior of the storage bin 1 is provided on the outer wall of the storage bin 1, and the gear 5 located outside the storage bin 1 meshes with the teeth 19 on the inner annular seat 16 after passing through the through slot 13. The inner cavity of the discharge hopper 3 is plugged with the movable shaft 4, and the material discharge outlet 22 is sleeved on the outside of the movable shaft 4. The discharge hopper 3 is fixedly sleeved on the outside of the movable shaft 4 through the mounting hole provided in the center, and the material discharge outlet 22 is fixedly sleeved on the outer wall of the movable shaft 4.

[0041] When the yeast culture inside the storage bin 1 is discharged, the motor 15 is connected to a power source, so that the output shaft of the motor 15 drives the gear 5 to rotate. The teeth 19 meshing with the gear 5 drive the inner annular seat 16 to rotate, so that the inner annular seat 16 drives the discharge hopper 3 to rotate, so that the discharge hopper 3 drives the discharge outlet 22 located inside the discharge hole 23 to rotate through the movable shaft 4. The discharge outlet 22 rotates synchronously with the discharge hopper 3, which can ensure the discharge of the yeast culture flow while ensuring the discharge of the material, avoiding blockage in the discharge process, thereby ensuring the efficiency of the discharge process.

[0042] It is worth noting that a bulk material tray 6 is rotatably arranged between the supporting hopper 8 and the discharging hopper 3, and the bulk material tray 6 is sleeved on the outside of the movable shaft 4, and the movable shaft 4 passes through the inner cavity of the discharge hole 23. The discharge outlet 22, the bulk material tray 6 and the discharging hopper 3 are fixedly sleeved on the outside of the movable shaft 4 from top to bottom in sequence. The discharge outlet 22, which is the auger blade, is fixedly sleeved on the outside of the movable shaft 4 from top to bottom in sequence, so that both ends of the discharge outlet 22 extend to the outside of both sides of the discharge hole 23. The upper end of the movable shaft 4 passes through the discharge hole 23 and extends to the upper space of the storage bin 1, and the lower end of the movable shaft 4 passes through the discharging hopper 3 and extends to the outside, so that the bulk material tray 6 rotates synchronously with the discharging hopper 3 and the discharge outlet 22.

[0043] The yeast culture discharged from the discharge hole 23 falls on the rotating bulk disc 6. The centrifugal force generated by the bulk disc 6 causes the yeast culture to scatter circumferentially onto the inner wall of the discharge hopper 3, avoiding accumulation of directly fallen materials, thereby ensuring the smoothness of the yeast culture discharge process.

[0044] In addition, the rotating support assembly includes an outer annular seat 9 embedded in the inner cavity of the storage bin 1. The outer annular seat 9 is rotatably arranged outside the inner annular seat 16, and balls 21 are circumferentially arranged between the inner annular seat 16 and the outer annular seat 9. The stepped outer annular seat 9 fits the inner wall of the storage bin 1 and is fixed in the inner cavity. The inner cavity aperture of the outer annular seat 9 corresponds to that of the inner annular seat 16, so that the outer annular seat 9 is sleeved on the outside of the inner annular seat 16. A circle of movable grooves 25 are continuously opened in sequence on the inner wall of the outer annular seat 9 relative to the inner annular seat 16, and a circle of slide grooves 24 are opened on the outer wall of the inner annular seat 16 and at a position corresponding to the movable grooves 25, and balls 21 are movably embedded in the movable cavity formed by each movable groove 25 and the slide groove 24.

[0045] During the rotation of the inner annular seat 16, the inner annular seat 16 drives the slide groove 24 to slide against the outer wall of the plurality of circumferential balls 21, and at the same time, each ball 21 slides on the inner wall of each movable groove 25. The plurality of circumferential balls 21 ensure the stability of the rotation process of the inner annular seat 16, thereby ensuring the stability of the rotation process of the discharge hopper 3, and further ensuring the stability of the discharge process.

[0046] In addition, an annular guide seat 7 is fixedly installed on the top of the outer annular seat 9, and the annular guide seat 7 is embedded in the inner wall of the storage bin 1. The longitudinal section of the annular guide seat 7 is triangular, and the annular guide seat 7 is fitted to the inner wall of the storage bin 1 and is fixed to the top of the outer annular seat 9. The inner wall of the annular guide seat 7 between the inner wall of the storage bin 1 and the discharge hopper 3 is an inclined surface. The discharge hopper 3 is embedded in the central through hole of the annular guide seat 7, and the connection between the annular guide seat 7 and the discharge hopper 3 is an arc.

[0047] In the process of the scattering disc 6 driving the yeast culture falling on the surface to scatter to the periphery, the material scattered to the outside of the discharge hopper 3 falls from the storage bin 1 onto the annular guide seat 9, and the material slides into the discharge hopper 3 through the inclined surface of the annular guide seat 9. Then, the yeast culture is sent into the discharge port 10 through the rotating discharge hopper 3, thereby preventing the yeast culture from being retained in the storage bin 1, thereby avoiding waste.

[0048] Furthermore, the connection between the annular guide seat 7 and the discharge hopper 3 is an arc-shaped edge. The arc-shaped edge allows the yeast culture flying out of the bulk material tray 6 to slide onto the discharge hopper 3, and the arc-shaped edge of the connection makes the slide more smooth, thereby ensuring the smoothness of the yeast culture discharge process.

[0049] The top of the bulk material tray 6 is circumferentially provided with a material separator 20. The material separator 20 allows the yeast culture falling on the rotating bulk material tray 6 to fall into the inside of the discharge hopper 3 more evenly, thereby ensuring the smoothness of the yeast culture discharge process.

[0050] The bottom of the storage bin 1 is provided with a discharge port 10, and a valve 11 is provided on the discharge port 10. The valve 11 may be a solenoid valve or a manual valve. The discharge port 10 is fixed at the bottom of the storage bin 1 and is sealed and connected to the inside of the storage bin 1. The opening and closing of the discharge port 10 is controlled by the valve 11, thereby bringing convenience to the operation process of relevant personnel.

[0051] The discharge pipe 17 is arranged obliquely between the outer wall of the discharge hopper 3 and the inner wall of the storage bin 1. The smoothness of the yeast culture discharge process is ensured by the obliquely arranged discharge pipe 17.

[0052] The present embodiment is a storage device for yeast culture, and its working principle is as follows: when storing yeast culture, screw the bolt 14 to remove the bin cover 2. After opening the top of the storage bin 1, put the yeast culture inside, and then cover the bin cover 2 on the top of the storage bin 1 and fix it with the bolt 14.

[0053] When the yeast culture in the storage bin 1 needs to be taken out, the motor 15 is connected to a power source so that the output shaft of the motor 15 drives the gear 5 to rotate. The teeth 19 meshing with the gear 5 drive the inner annular seat 16 to rotate, and the inner annular seat 16 drives the discharge hopper 3 to rotate. The discharge hopper 3 drives the discharge outlet 22 located inside the discharge hole 23 to rotate through the movable shaft 4. The yeast culture located near the discharge hole 23 is sequentially dropped from the discharge hole 23 by the rotating discharge outlet 22 as the auger blades rotate. The dropped yeast culture falls on the surface of the rotating bulk material disc 6, and the centrifugal force formed by the bulk material disc 6 causes the yeast culture to be scattered circumferentially onto the inner wall of the discharge hopper 3.

[0054] The yeast culture then falls onto the discharge hopper 3 , and the yeast culture in the hopper is discharged to the outside through a plurality of circumferential discharge pipes 17 by the rotating discharge hopper 3 . Finally, the discharge port 10 is opened by the valve 11 to collect and use the discharged yeast culture.
