Description

Technical Field

[0001] This utility model relates to the field of enoki mushroom broth feeding technology, specifically to a feeding structure for an expanded culture vessel of enoki mushroom broth. Background Technology

[0002] In the process of expanding the culture of enoki mushroom mycelium, the rationality of the feeding structure directly affects the uniformity of mixing between the mycelium and the culture medium, the utilization rate of raw materials, and the stability of the culture environment. It is a key factor in determining the yield and quality of the mycelium.

[0003] Currently, the commonly used feeding structures for expanding the culture tank of *Flammulina velutipes* spawn, while achieving basic spawn delivery, still suffer from numerous technical shortcomings in practical applications. Existing technologies mostly rely on a single hopper or straight pipe to directly inject the spawn into the culture tank, lacking precise guidance and graded dispersion design. This leads to problems such as spawn drift to one side and concentrated fall, resulting in localized accumulation of spawn on the culture medium surface (excessive concentration can cause anaerobic deterioration), while areas far from the inlet lack sufficient spawn coverage (low culture medium utilization). This uneven dispersion directly causes significant differences in the spawn growth environment in different areas of the culture tank, ultimately resulting in large batch quality fluctuations, reduced effective viable cell counts, and severely impacting the efficiency and stability of expanded culture. To address these issues, this invention provides a feeding structure for expanding the culture tank of *Flammulina velutipes* spawn. Utility Model Content

[0004] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a feeding structure for an expanded culture vessel of enoki mushroom mycelium. Through a guide pipe, a diversion plate, and a feeding plate, the mycelium can be evenly added into the interior of the culture vessel, achieving uniform distribution throughout the entire vessel, effectively avoiding localized concentration anomalies, ensuring a consistent culture environment, and thus improving the growth efficiency and quality of the mycelium.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a feeding structure for a large-scale culture vessel for enoki mushroom mycelium, comprising: A fixed cylinder is installed at the feed inlet of the culture vessel, and a feeding hopper is provided at the upper end of the fixed cylinder; The flow divider plate is installed inside the fixed cylinder, directly below the feeding hopper; Multiple material-discharging plates are used to collect the bacterial liquid flowing down from the distribution plate. The multiple material-discharging plates are located below the fixed cylinder, rotatably connected to the fixed cylinder, and evenly distributed along the circumference of the distribution plate.

[0006] Preferably, the shape of the diverter plate is an arch shape that is high in the middle and low around the edges.

[0007] Preferably, a diversion pipe is provided above the flow divider plate. The diversion pipe is fixedly installed inside the fixed cylinder and communicates with the feeding hopper. The distance between the flow divider plate and the diversion pipe is adjustable.

[0008] Preferably, the diverter plate is installed inside the fixed cylinder via a lifting frame, which is driven to rise and fall by an electric push rod installed on the upper end face of the fixed cylinder.

[0009] Preferably, the lifting frame includes: Multiple buffer rods are fixedly installed on the diverter plate, and the upper end of the buffer rods passes through the fixed cylinder; A connecting ring is fixedly installed on the upper end of multiple buffer rods and is fixedly connected to the output rod of the electric push rod.

[0010] Preferably, the buffer rod includes: The lower rod is fixedly installed on the distributor plate; The upper rod is fixedly connected to the connecting ring; The upper rod and the lower rod are connected by an elastic part.

[0011] Preferably, the elastic part includes two elastic arc rods, the openings of the two elastic arc rods facing each other, and one end of the elastic arc rod is fixedly connected to the lower rod and the other end is fixedly connected to the upper rod.

[0012] Preferably, an elastic ring is fixedly installed at the lower end of the drainage tube. The lower end of the elastic ring is inclined to form a cone shape that is thicker at the bottom and thinner at the top, and the lower end of the elastic ring abuts against the diversion plate.

[0013] Preferably, the material-slinging plate is an arch shape that is high in the middle and low around the edges.

[0014] Preferably, the material throwing plate is fixedly connected to a drive shaft, the upper end of the drive shaft passes through the fixed cylinder and is fixedly connected to a gear, the gear meshes with a gear ring rotatably mounted on the fixed cylinder, any gear is fixedly connected to the output shaft of the motor, and the motor is mounted on the fixed cylinder.

[0015] The beneficial effects of this utility model are as follows: This invention, through the design of a drainage pipe, a distribution plate, and a dispensing plate, enables the drainage pipe to precisely guide the bacterial solution to the center of the distribution plate. The arched distribution plate, which is higher in the center and lower around the edges, allows the bacterial solution to flow evenly along the plate surface using gravity. The distributed bacterial solution falls onto the dispensing plate, which further dispenses the solution onto the inner wall of the culture vessel and different areas, achieving uniform distribution throughout the entire vessel. This effectively avoids localized concentration anomalies, ensures a consistent culture environment, and thus improves the growth efficiency and quality of the bacterial solution.

[0016] This invention, through the setting of an elastic ring and an electric push rod, enables the adjustment of the height of the diverter plate, thereby controlling the clamping force of the elastic ring against the diverter plate. This allows for the control of the feed rate based on real-time conditions. Furthermore, the setting of the elastic ring can prevent the bacterial liquid from impacting the diverter plate and splashing onto the inner wall of the fixed cylinder, thus avoiding waste of the bacterial liquid.

[0017] This invention, through the setting of an elastic arc rod, achieves the absorption of impact force through elastic deformation when the bacterial liquid impacts the diversion plate, which not only protects the diversion plate and connecting parts, but also reduces splashing when the bacterial liquid impacts the diversion plate, allowing the bacterial liquid to flow down the diversion plate more effectively.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a feeding structure for an expanded culture vessel of enoki mushroom mycelium, such as... Figures 1 to 6 As shown.

[0028] Example 1: A feeding structure for a large-scale culture vessel of enoki mushroom mycelium includes a fixed cylinder 1, a diversion plate 2, and multiple material throwing plates 3. The fixed cylinder 1 is a cylindrical metal cylinder, which is fixedly installed at the inlet of the culture vessel. A funnel-shaped feeding hopper is welded to its upper end. The lower outlet of the feeding hopper is connected to the inside of the fixed cylinder 1 and is used to receive the mycelium liquid transported from the outside.

[0029] A flow divider 2 is installed in the center of the interior of the fixed cylinder 1. The flow divider 2 is a rounded metal plate with a higher center and lower edges, made of 304 stainless steel (corrosion resistant and with a smooth surface to reduce bacterial liquid residue). A drainage pipe 4 is located directly above the flow divider 2. The drainage pipe 4 is a cylindrical pipe with its upper end welded to the lower outlet of the feeding hopper and its lower end extending directly above the flow divider 2. After the bacterial liquid enters from the feeding hopper, it falls vertically through the drainage pipe 4 to the center of the flow divider 2. The rounded shape of the flow divider 2 uses gravity to make the bacterial liquid flow evenly around the perimeter of the plate, avoiding concentrated deviation when the bacterial liquid falls directly.

[0030] Multiple material-throwing plates 3 are provided below the diversion plate 2. The multiple material-throwing plates 3 are evenly distributed along the circumference of the diversion plate 2 and are all located at the lower end outlet of the fixed cylinder 1. When the fixed cylinder 1 is installed on the culture vessel, the material-throwing plates 3 extend into the interior of the culture vessel. Each material-throwing plate 3 is a round arch shape with a high center and low periphery. A drive shaft is fixedly installed on the material-throwing plate 3. The upper end of the drive shaft passes through the upper end face of the fixed cylinder 1 and extends to the outside of the fixed cylinder 1 before a gear 11 is welded thereon. The gears 11 mesh with the gear ring 12 rotatably installed on the outer wall of the fixed cylinder 1. Any gear 11 is also fixedly connected to the output shaft of the motor 13 through a coupling. The motor 13 is fixed on the outer wall of the fixed cylinder 1 through a bracket.

[0031] When the motor 13 starts, the output shaft drives the gear 11 connected to it to rotate. The gear 11 drives the other gears 11 to rotate synchronously through the gear ring 12, thereby causing multiple throwing plates 3 to rotate synchronously. The bacterial liquid flowing down from the periphery of the diversion plate 2 falls evenly onto the four rotating throwing plates 3. The arched throwing plates 3 use centrifugal force to throw the bacterial liquid out in all directions, which is thrown into different areas inside the culture vessel, so as to achieve uniform distribution of the bacterial liquid throughout the culture vessel and avoid local accumulation.

[0032] Example 2: Based on Example 1, in order to control the flow rate of the bacterial liquid, the diverter plate 2 is installed inside the fixed cylinder 1 through a lifting frame. The lifting frame is driven by an electric push rod 5. The cylinder of the electric push rod 5 is fixed to the upper end face of the fixed cylinder 1 by bolts, and its output rod is fixedly connected to the connecting ring 6.

[0033] The connecting ring 6 is a circular metal plate with multiple buffer rods evenly fixed on its lower surface. The lower end of the buffer rod passes through the fixed cylinder 1 and is fixedly connected to the upper surface of the diversion plate 2, thereby connecting the diversion plate 2 and the electric push rod 5. By controlling the extension length of the output rod of the electric push rod 5, the height of the diversion plate 2 can be controlled, thereby controlling the distance between the diversion plate 2 and the lower end of the drainage pipe 4, and thus controlling the flow rate of the bacterial solution.

[0034] The buffer rod consists of a lower rod 7, an upper rod 8, and an elastic part. The lower end of the lower rod 7 is vertically welded to the upper surface of the diversion plate 2, and the upper end of the upper rod 8 is welded to the lower surface of the connecting ring 6. The elastic part is located between the lower rod 7 and the upper rod 8 and consists of two opposing elastic arc rods 9. The elastic arc rods 9 are made of spring steel, with one end welded to the upper end of the lower rod 7 and the other end welded to the lower end of the upper rod 8. When the bacterial liquid impacts the diversion plate 2 from the drainage pipe 4, the impact force is transmitted to the elastic arc rods 9 through the lower rod 7. The two elastic arc rods 9 bend and deform in opposite directions due to the force, absorbing the impact energy. This not only prevents damage to the diversion plate 2 and the lifting frame due to rigid impact but also reduces splashing caused by the impact of the bacterial liquid, allowing the bacterial liquid to flow more smoothly down the diversion plate 2.

[0035] Example 3: To prevent bacterial liquid from splashing and remaining on the inner wall of the fixed cylinder 1, thus wasting the bacterial liquid, an elastic ring 10 is fixedly installed at the lower opening of the drainage pipe 4. The elastic ring 10 is made of food-grade silicone and has good elasticity. The lower end of the elastic ring 10 is always pressed against the upper side of the diversion plate 2. When the electric push rod 5 drives the diversion plate 2 to rise and fall, the conical lower end of the elastic ring 10 will adapt to the change in the height of the diversion plate 2: if it is necessary to increase the feed rate, the electric push rod 5 drives the diversion plate 2 to rise, the contact force between the elastic ring 10 and the diversion plate 2 decreases, and the bacterial liquid can flow out more quickly.

[0036] If the feed rate needs to be reduced, the electric push rod 5 drives the diversion plate 2 to descend, the elastic ring 10 is compressed, and the flow rate of the bacterial liquid slows down.

[0037] The lower end of the elastic ring 10 is inclined to form a conical structure that is thinner at the top and thicker at the bottom. The conical structure can completely guide the bacterial liquid flowing out of the drainage tube 4 to the diversion plate 2, avoiding the bacterial liquid from splashing onto the inner wall of the fixed cylinder 1 and reducing the waste of bacterial liquid.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
