Description

Technical Field

[0001] This utility model relates to the field of edible fungus culture medium preparation technology, and in particular to an edible fungus culture medium stirring and scraping device. Background Technology

[0002] In the preparation of edible mushroom substrate, mixing is a crucial step, directly affecting the uniformity and quality of the substrate. Mainstream mixing equipment primarily uses rotating mixing plates within a container to achieve material mixing and output. However, to prevent friction and damage caused by container non-roundness or runout errors of the agitator's outer circumference, a safety gap of at least 15mm must be maintained between the outer circumference of the agitator and the inner circumference of the container. This results in a significant amount of material remaining in this safety gap, unable to be effectively mixed and utilized. This residual material not only wastes raw materials but may also deteriorate due to prolonged retention, thus affecting the overall quality of the substrate and the growth of the edible mushrooms. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a stirring and scraping device for edible fungi culture media in order to address the shortcomings of the existing technology. This device can effectively prevent material residue, improve material utilization, and ensure the high quality and stability of the culture media.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The air distribution mechanism includes an air inlet main pipe 7 disposed in the mixing shaft 3. One end of the air inlet main pipe 7 extends out of the end face of the mixing shaft 3 and is connected to an air inlet and an air outlet. The air inlet and the air outlet are respectively provided with an air inlet valve 20 and an air outlet valve 21. A plurality of air inlet branch pipes 8 are disposed on the outer periphery of the mixing shaft 3 and communicate with the air inlet main pipe 7. The other end of each air inlet branch pipe 8 is connected to one or more pneumatic scrapers 6 for air supply. The intake manifold 8 can be installed separately or inside the support rod 5. In this embodiment, the number of intake manifolds 8 corresponds to the number of support rods 5, and the intake manifolds 8 and support rods 5 are fixedly connected as one unit.

[0026] The stirring plate 4 is specifically a ribbon stirring plate, and one or more may be provided; the pneumatic scraper 6 is provided on the inner side of the stirring plate 4, including a guide groove 12 arranged radially on the stirring plate 4 along the stirring shaft 3 and a movable column 9 slidably arranged in the guide groove 12. Multiple sealing rings 18 are provided between the movable column 9 and the guide groove 12. The movable column 9 is provided with a scraping surface 10 for pressing against the inner wall of the tank body 1. The scraping surface 10 is specifically the outer end face of the movable column 9; the gas distribution mechanism also includes a gas distribution chamber 11 provided in the stirring plate 4. The gas distribution chamber 11 is connected to the other end of each air inlet branch pipe 8. At the same time, the gas distribution chamber 11 is also connected to each guide groove 12 to distribute the gas supplied in the air inlet branch pipe 8 to each guide groove 12, push the movable column 9 out, and make the scraping surface 10 press against the inner wall of the tank body 1.

[0027] The guide groove 12 is a through groove open at both ends. A sealing plug 13 is connected to the end of the guide groove 12 near the stirring shaft 3. A shim rod 14 is fixedly provided at the end of the movable column 9 near the stirring shaft 3. When the shim rod 14 abuts against the sealing plug 13, the air port of the air distribution chamber 11 connected to the guide groove 12 is located between the movable column 9 and the sealing plug 13, so as to apply an outward thrust to the inner end face of the movable column 9.

A stop ring 15 that cooperates with the anti-disengagement opening is fixedly provided on the outer side of the movable column 9 to prevent the movable column 9 from disengaging from the guide groove 12.

[0028] Working Principle: This utility model discloses a stirring and scraping device for edible fungi culture medium. In use, compressed air is first introduced into the main air inlet pipe 7 through the air inlet. The gas then enters the distribution chamber 11 through the branch air inlet pipe 8 and is distributed to each guide groove 12. As the gas pressure increases, the movable column 9 slides outward within the guide groove 12 until the scraping surface 10 is tightly attached to the inner wall of the tank 1. At this time, the stirring shaft 3 begins to rotate, driving the stirring plate 4 and the pneumatic scraper 6 to rotate together, thus achieving stirring and scraping of the material. When scraping needs to be stopped, the gas in the main air inlet pipe 7 can be extracted through the air extraction port, and the movable column 9 retracts into the guide groove 12 under negative pressure.

[0029] [Example 2] In Example 1, the pneumatic scraper 6 is located inside the mixing plate 4, which increases the thickness of the scraper plate and slightly reduces the mixing effect. Example 2 differs from Example 1 in that it provides a different structure for the pneumatic scraper 6 to reduce the thickness of the scraper plate and enhance the mixing effect.

[0030] Please refer to Figure 5-7 A mixing and scraping device for edible fungi culture medium includes a tank body 1 and a mixer 2. The mixer 2 includes a mixing shaft 3 disposed in the tank body 1, a mixing plate 4 disposed on the outer periphery of the mixing shaft 3, a plurality of support rods 5 fixedly connected between the mixing shaft 3 and the mixing plate 4, a plurality of pneumatic scrapers 6 disposed on one side of the mixing plate 4, and an air distribution mechanism for driving the pneumatic scrapers 6 to pop out. The air distribution mechanism includes an air inlet main pipe 7 disposed in the mixing shaft 3. One end of the air inlet main pipe 7 extends out of the end face of the mixing shaft 3 and is connected to an air inlet and an air outlet. The air inlet and the air outlet are respectively provided with an air inlet valve 20 and an air outlet valve 21. A plurality of air inlet branch pipes 8 are disposed on the outer periphery of the mixing shaft 3 and communicate with the air inlet main pipe 7. The other end of each air inlet branch pipe 8 is connected to one or more pneumatic scrapers 6 for air supply. The intake manifold 8 can be installed separately or inside the support rod 5. In this embodiment, the number of intake manifolds 8 corresponds to the number of support rods 5, and the intake manifolds 8 and support rods 5 are fixedly connected as one unit.

[0031] The mixing plate 4 is specifically a ribbon mixing plate, and one or more may be provided; the pneumatic scraper 6 is provided on one side of the mixing plate 4, including a support seat 16 mounted on the end of each support rod 5 away from the mixing shaft 3. The support seat 16 and the support rod 5 are detachably connected by bolts. The support seat 16 is provided with a plurality of guide grooves 12 parallel to the axis of the support rod 5. The guide grooves 12 are evenly spaced. Each guide groove 12 is slidably provided with a movable column 9. The end of each movable column 9 away from the mixing shaft 3 is fixedly connected to a scraper 17. The scraper 17 is provided on one side of the mixing plate 4. The scraper 17 is provided with a scraping surface 10 for pressing against the inner wall of the tank body 1. The scraping surface 10 is specifically the outer end face of the scraper 17. The support seat 16 is also provided with guide bolts 19 fixedly connected to the scraper 17.

[0032] The gas distribution mechanism also includes a gas distribution chamber 11 located in each support 16. Each gas distribution chamber 11 is connected to the other end of an air inlet branch pipe 8 and connected to each guide groove 12 in the support 16 to supply gas, so as to distribute the gas supplied in the air inlet branch pipe 8 to each guide groove 12, push the movable column 9 to extend, and make the scraping surface 10 of the scraper 17 press against the inner wall of the tank 1.

[0033] Working Principle: This utility model discloses a stirring and scraping device for edible fungi culture medium. In use, compressed air is first introduced into the main air inlet pipe 7 through the air inlet. The gas then enters the gas distribution chamber 11 through the air inlet branch pipe 8 and is distributed to each guide groove 12. As the gas pressure increases, the movable column 9 slides outward within the guide groove 12, pushing out the scraper plate 17 until its scraping surface 10 is tightly against the inner wall of the tank body 1. At this time, the stirring shaft 3 begins to rotate, driving the stirring plate 4 and the pneumatic scraper 6 to rotate together, achieving stirring and scraping of the material. When scraping needs to be stopped, a vacuum can be drawn into the main air inlet pipe 7 through the air extraction port, and the movable column 9 retracts into the guide groove 12 under negative pressure. Compared with Embodiment 1, in this embodiment, the pneumatic scraper 6 is located on one side of the stirring plate 4, which can effectively reduce the local thickness of the stirring plate 4, thereby potentially enhancing the stirring effect and optimizing the overall structure.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
