DETAILED DESCRIPTION

[0016] The following will be described in detail in combination with the accompanying drawings Figs. 1-3 The application will be further described in detail.

[0017] The application embodiment discloses an edible fungus culture medium stirring device. Figs. 1-3The utility model relates to an edible fungus culture medium stirring device which is mainly composed of a stirring tank 1 with a double-layer tank body and a heat preservation liquid cavity, an upper cover 2, a driving motor 3, a stirring shaft 4, a downflow mixing impeller 5, a mixed flow impeller 6, an upflow mixing impeller 7 and other components.

[0018] With reference to Fig. 2 The stirring tank 1 serves as the container body of the whole device, and the double-layer tank body structure with the heat preservation liquid cavity inside has multiple advantages. On the one hand, the double-layer tank body can effectively reduce heat loss and maintain the temperature stability of the culture medium in the tank, thus creating a suitable temperature environment for the growth of edible fungi, which is particularly important for some edible fungi varieties that are sensitive to temperature and helps to promote the growth, reproduction and metabolic activity of microorganisms and improve the quality and utilization rate of the culture medium. On the other hand, the presence of the heat preservation liquid cavity can to some extent buffer the influence of external temperature changes on the culture medium in the tank, enhance the environmental adaptability and stability of the whole stirring device, ensure that the stirring process is not disturbed by temperature fluctuations and guarantee the continuity and stability of the stirring operation.

[0019] With reference to Fig. 2 The upper cover 2 is installed on the stirring tank 1, which not only plays a role in sealing the stirring tank 1 to prevent impurities from entering the tank and contaminating the culture medium, but also provides a stable mounting platform for the driving motor 3. The driving motor 3 serves as the power source of the stirring device, and its output shaft is connected to the main shaft 401 of the stirring shaft 4, providing continuous and stable power for the whole stirring process through the rotation of the motor. After starting, the driving motor 3 can accurately control the rotation speed and direction of the main shaft 401, ensuring the stability and consistency of the stirring action, thus guaranteeing that the culture medium can be fully and uniformly stirred and laying a foundation for efficient mixing.

[0020] With reference to Fig. 2, the stirring shaft 4 is the key component to realize the stirring of the culture medium, and the main shaft 401 is rotatably arranged on the upper cover 2, which ensures the stability and precision of rotation. The downflow mixing impeller 5, the mixed flow impeller 6 and the upflow mixing impeller 7 sleeved on the main shaft 401 respectively undertake different direction stirring tasks, and realize all-round mixing through synergistic effect. The outer ring stirring rod 402 on the outer side of the main shaft 401 is connected with the main shaft 401 through the connecting rod, and this connection mode enables the outer ring stirring rod 402 to rotate synchronously with the main shaft 401, so as to effectively stir the culture medium in the outer ring, especially in the corner part inside the stirring tank 1. In the stirring process, the material accumulation dead angle often occurs in these corner parts, and the rotation of the outer ring stirring rod 402 can roll the material in these dead angle areas into the stirring range, so that the distribution of the culture medium in the whole stirring tank 1 is more uniform, the local material concentration is avoided to be too high or too low, the culture medium in each place can fully participate in the mixing process, the uniformity and completeness of mixing are improved, and a uniform and consistent nutrient environment is provided for the growth of edible fungi.

[0021] With reference to Fig. 3 , the several forward inclined blades 502 arranged on the shaft sleeve one 501 of the downflow mixing impeller 5 play a unique role when the main shaft 401 rotates. The inclination angle and shape of the forward inclined blades 502 are carefully designed, and when the main shaft 401 drives the rotation thereof, the blades can use the inclined surface structure thereof to push the culture medium from the top to the bottom, forming a top-down material flow. This downflow effect helps to break the stratification phenomenon of the culture medium in the vertical direction, promotes the mixing and circulation of the material. For example, when new culture medium ingredients are added or the material is initially mixed, the material at the top is often loose, while the material at the bottom may be accumulated due to gravity. The stirring of the forward inclined blades 502 can make the material at the top penetrate downward quickly, fully contact with the material at the bottom, speed up the mixing process, improve the mixing efficiency, and ensure uniform distribution of the culture medium ingredients, thereby providing balanced nutrient supply for the growth of edible fungi.

[0022] With reference to Fig. 3 , the reverse inclined blades 702 on the shaft sleeve three 701 of the upflow mixing impeller 7 cooperate with the downflow mixing impeller 5 to realize the flow of the material in the opposite direction. When the main shaft 401 rotates, the reverse inclined blades 702 push the culture medium from the bottom to the top, and the main function thereof is to prevent the solid particles from depositing at the bottom. In the stirring process, the solid components in the culture medium, such as sawdust and wheat bran, may gradually sink due to gravity, and if not timely moved, the material at the bottom will be accumulated, which affects the mixing effect and the quality of the culture medium. The upflow effect of the reverse inclined blades 702 can bring the material at the bottom back to the upper part, so that the solid particles at the bottom participate in the overall mixing process again, avoid the material from sinking to the bottom, ensure the uniformity and stability of the culture medium in the vertical direction, and also be beneficial to the uniform distribution of microorganisms in the whole culture medium, thereby promoting the uniform growth of edible fungi.

[0023] Referring to Fig. 3 The V-shaped stirring plates 602 outside the shaft sleeve two 601 of the mixed flow impeller 6 are fixedly connected with the outer ring stirring rods 402, and this connection mode enhances the overall structural strength and stability of the stirring device. When the main shaft 401 rotates, the V-shaped stirring plates 602 can keep the passing culture medium flowing in the horizontal direction, and ensure that the material is uniformly distributed in the horizontal direction. In the actual stirring process, the flow of the culture medium in the vertical direction may cause uneven distribution of the material in the horizontal direction, and the stirring action of the V-shaped stirring plates 602 can effectively make up for this deficiency, so that the material forms a stable circulation in the horizontal plane, further promotes the omnidirectional mixing of the culture medium, and improves the uniformity and fineness of the mixing, thereby providing a more stable and balanced nutrient environment for the growth of edible fungi.

[0024] The implementation principle of the edible fungus culture medium stirring device according to the embodiment of the application is as follows: in the preparation process of the edible fungus culture medium, various raw materials are put into the stirring tank 1 according to a certain proportion and order, the upper cover 2 is closed, and the sealing of the stirring tank 1 is ensured to prevent the material from spilling out and foreign matters from entering.

[0025] The driving motor 3 is started, and the driving motor 3 transmits power to the main shaft 401 through a coupling or other connection mode, so that the main shaft 401 starts to rotate at a high speed. The main shaft 401 drives the outer ring stirring rod 402 to rotate together, and the outer ring stirring rod 402 can effectively stir the culture medium in the corner parts of the inside of the stirring tank 1 due to its position close to the inner wall of the stirring tank 1. These corner parts are often neglected by the traditional stirring device, but the device can disperse the material accumulated in the corners and make it fully participate in the overall stirring and mixing process through the arrangement of the outer ring stirring rod 402, thereby avoiding the deposition and caking of the material in the corners and ensuring the uniformity of the culture medium.

[0026] With the rotation of the main shaft 401, the shaft sleeve one 501 of the downflow mixing impeller 5 drives the forward inclined blades 502 to rotate. The special shape and angle design of the forward inclined blades 502 enable them to generate a downward thrust on the culture medium during rotation, and push the culture medium at the top of the stirring tank 1 to the bottom. This top-down material flow can effectively mix the newly added raw material at the top with the existing material at the bottom, promote the circulation and uniform distribution of the material in the whole stirring tank 1, speed up the mixing speed, and improve the mixing efficiency.

[0027] At the same time, the shaft sleeve three 701 of the up-flow mixing impeller 7 drives the reverse inclined blade 702 to rotate. The inclination direction of the reverse inclined blade 702 is opposite to that of the forward inclined blade 502, and the reverse inclined blade 702 pushes the culture medium at the bottom of the stirring tank 1 upwards during rotation. This action has multiple benefits: first, it can prevent heavier materials such as solid particles from depositing at the bottom, avoiding uneven mixing caused by material deposition; second, it brings the material at the bottom to the upper part, so that the material at the bottom can also fully participate in the entire stirring process, further enhancing the mixing effect and ensuring the uniformity of the culture medium in the vertical direction.

[0028] The shaft sleeve two 601 of the mixed-flow impeller 6 drives the V-shaped stirring plate 602 to rotate, and the V-shaped stirring plate 602 is fixedly connected with the outer circle stirring rod 402, so that it can generate a horizontal force on the passing culture medium during rotation. This horizontal stirring action can make the culture medium uniformly distributed in the horizontal plane, avoiding the stratification of materials in the horizontal direction, and further improving the mixing uniformity of the culture medium.

[0029] Through the coordinated action of the down-flow mixing impeller 5, the mixed-flow impeller 6 and the up-flow mixing impeller 7 in the vertical and horizontal directions, and the effective stirring of the outer circle stirring rod 402 on the corner parts, the edible mushroom culture medium in the stirring tank 1 can be mixed in all directions and efficiently in a short time, ensuring the stability of the culture medium quality and providing a strong guarantee for the good growth of edible mushrooms.
