[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, a stirring assembly driven by a driving assembly is arranged inside a fermentation tank body, and a first stirring rod and a second stirring rod in the stirring assembly can stir the culture medium in the fermentation tank body. The first stirring rod and the second stirring rod are arranged in a staggered and inclined state. During the stirring process, a part of the structure can be separated from the liquid surface of the culture medium. In the process of the stirring structure being separated from the culture medium, the stirring structure can draw an opening in the culture medium, allowing the air in the device to enter the interior of the culture medium from the opening, thereby playing a role in improving the solubility of oxygen, thereby solving the problem of slow oxygen diffusion speed and small range caused by high viscosity of the culture medium, and the stirring structure in the culture medium can stir the culture medium at a slower speed, allowing oxygen to diffuse to various parts of the culture medium.

[0020] 2. In the present invention, the servo motor in the driving assembly drives the transmission rod through the belt transmission assembly, and the transmission rod is used to continuously push the semicircular frame. The semicircular frame is connected to the movable block. The transmission rod will push the movable block up and down through the semicircular frame, and continuously remove the stirring assembly from the culture medium, thereby creating more gaps on the liquid surface of the culture medium, expanding the contact area between the culture medium and the air. A larger contact area means more opportunities for substance exchange. For the culture medium, the increase in the contact area with the air allows the substances therein to better interact with the oxygen in the air. In this case, the solubility of oxygen in the culture medium can be further improved.

[0021] 3. In the present invention, after the stirring assembly enters below the liquid surface, the connecting rod will push the cylinder through the guide groove, and drive the vertical rod through the cylinder to achieve the purpose of driving the entire stirring assembly to rotate, so that the stirring assembly is in a rotating state while stirring the culture medium.

DETAILED DESCRIPTION

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

[0032] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown: an edible fungus liquid deep fermentation device, comprising a fermentation box 1, a partition plate 5 is fixedly installed on the inner wall of the fermentation box 1, a support frame 7 is fixedly installed on the upper surface of the partition plate 5, a driving component 6 is fixedly installed on the top of the partition plate 5, and one end of the driving component 6 is fixedly connected to a stirring component 9;

[0033] The stirring assembly 9 includes a gear box 91, a first stirring rod 93 and a second stirring rod 94. The bottom of the gear box 91 is fixedly connected with a directional pipe 92. The two directional pipes 92 are symmetrically and tiltedly arranged along the center line of the gear box 91. The first stirring rod 93 is rotatably installed in one of the directional pipes 92, and the second stirring rod 94 is rotatably installed in the other directional pipe 92. The first stirring rod 93 and the second stirring rod 94 are staggered.

[0034] A sealing cover 2 is movably connected to the top of the fermentation box 1, a discharge chamber 4 is fixedly installed at the bottom of the fermentation box 1, a ventilation duct 3 is fixedly installed on one side of the sealing cover 2, a through hole 8 is opened inside the partition plate 5, and a stirring assembly 9 is located below the through hole 8.

At the same time, the ventilation pipe 3 is connected to the external oxygen production equipment to continuously add oxygen to the fermentation box 1. If the dissolved oxygen is insufficient, use the stirring component 9 to stir the culture medium. When the mycelium growth in the culture medium reaches a predetermined density, the fermentation is terminated and the fermented edible fungi are taken out from the discharge chamber 4;

[0036] The stirring assembly 9 is arranged below the partition plate 5, and the injected oxygen will pass through the through hole 8 and contact the culture medium. The power source of the stirring assembly 9 is provided by the driving assembly 6. The first stirring rod 93 and the second stirring rod 94 are arranged in an inclined and staggered state. During the fermentation process, the rotation of the first stirring rod 93 and the second stirring rod 94 can stir the culture medium to make the culture medium with higher viscosity flow. In this process, the first stirring rod 93 and the second stirring rod 94 with an inclined structure, the stirring blades are first in the culture medium, then separated from the liquid surface of the culture medium, and then enter the culture medium again. The purpose of stirring the culture medium can be achieved by reciprocating. In the process of the stirring blades of the first stirring rod 93 and the second stirring rod 94 being separated from the culture medium, the stirring blades can draw an opening in the culture medium. At this time, oxygen can enter the interior of the culture medium from the opening and dissolve into the culture medium, thereby playing a role in improving the solubility of oxygen, thereby solving the problem of slow oxygen diffusion speed and small range caused by high viscosity of the culture medium.

[0037] The first stirring rod 93 and the second stirring rod 94 are rotatably installed in the directional pipe 92, and the directional pipe 92 is arranged below the gear box 91 to ensure the structural stability of the first stirring rod 93 and the second stirring rod 94. The positions of the stirring assembly 9 and the driving assembly 6 are jointly determined by the partition plate 5 and the support frame 7.

[0038] Embodiment 2: According to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the driving assembly 6 includes a servo motor 61, which is fixedly mounted on the upper surface of the partition plate 5, and the output end of the servo motor 61 is fixedly connected to a belt transmission assembly 62, and a transmission rod 69 is fixedly connected to one side of a pulley in the belt transmission assembly 62, and the transmission rod 69 is rotatably connected to the support frame 7, and a guide frame 610 is fixedly mounted on one side of the support frame 7, and a movable block 64 is slidably connected to the inner side of the guide frame 610, and a semicircular frame 67 is fixedly connected to one side of the movable block 64, and the semicircular frame 67 is slidably connected to one end of the transmission rod 69, and the bottom of the movable block 64 is rotatably connected to a vertical rod 66, and the bottom of the vertical rod 66 is fixedly connected to the top of the gear box 91, and a cylinder 65 is slidably connected to the outer wall of the vertical rod 66, and the vertical rod 66 passes through the cylinder 65, and a guide convex strip 68 is fixedly mounted on the outer wall of the vertical rod 66, and the guide convex strip 68 is slidably connected to the inner wall of the cylinder 65, and the cylinder 65 is rotatably mounted on the bottom of the support frame 7.

[0039] In this embodiment, the connection terminal of the servo motor 61 in the driving component 6 is connected to the external power supply. When the driving component 6 is used, the servo motor 61 drives the transmission rod 69 through the belt transmission component 62, and the transmission rod 69 is used to push the semicircular frame 67, and the semicircular frame 67 is used to drive the movable block 64 up and down. When the movable block 64 moves up, the stirring component 9 will be taken away from the culture medium through the vertical rod 66. When the movable block 64 moves downward, the stirring component 9 will be reinserted into the culture medium. This process is mainly to allow the stirring component 9 to create more openings in the culture medium to allow oxygen to enter;

[0040] The arc structure in the semicircular frame 67 is mainly used to provide a period of time when the transmission rod 69 does not push the movable block 64. During this period of time, the stirring assembly 9 can be stably located in the culture medium or stay in the air for a period of time to allow the culture medium to recover. The vertical rod 66 is arranged in the cylinder 65, and a guide convex strip 68 is arranged between the vertical rod 66 and the cylinder 65 to prepare for the rotation of the entire stirring assembly 9, and the existence of the guide convex strip 68 will not affect the normal movement of the vertical rod 66.

[0041] A guide frame 610 is provided on the side of the support frame 7 to install the movable block 64 so as to determine the moving route of the movable block 64 .

[0042] Embodiment 3: According to Figure 4 and Figure 8 As shown, a double-headed rod 63 is fixedly connected to one side of the other pulley of the belt transmission assembly 62, and a connecting rod 612 is fixedly installed at the edge of the double-headed rod 63. The connecting rod 612 is symmetrically distributed along the center line of the double-headed rod 63, and the connecting rod 612 and the double-headed rod 63 are perpendicular to each other.

During the rotation of the pulley, the double-headed rod 63 is synchronously driven, and the double-headed rod 63 leaves the cylinder 65 from the notch 613. During this process, the cylinder 65 does not rotate. After the double-headed rod 63 leaves the cylinder 65, the connecting rod 612 enters the guide groove 611. During the subsequent rotation, the cylinder 65 is pushed, and the cylinder 65 is used to drive the vertical rod 66, so as to achieve the purpose of driving the entire stirring assembly 9 to rotate.

[0044] Embodiment 4: According to Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a connecting gear 96 is rotatably installed on the inner wall of the gear box 91, and an external gear 95 is fixedly connected to one side of the connecting gear 96 through an axis, and the external gear 95 is rotatably installed on the outer wall of the gear box 91. A toothed plate 10 is fixedly installed on the bottom of the support frame 7, and the external gear 95 is meshingly connected with the toothed plate 10. A first gear 97 is meshingly connected to the bottom of the connecting gear 96, and a second gear 98 is meshingly connected to one side of the first gear 97, and the second gear 98 does not contact the connecting gear 96. A second bevel gear 910 is fixedly installed on one end of the rod body of the first stirring rod 93 and one end of the rod body of the second stirring rod 94, and a first bevel gear 99 is fixedly installed on one side of the first gear 97 and one side of the second gear 98, and the first bevel gear 99 is meshingly connected with the second bevel gear 910.

[0045] In this embodiment, during the up and down movement of the stirring assembly 9, the external gear 95 will rotate under the action of the tooth plate 10, and synchronously drive the connecting gear 96 in the gear box 91, the connecting gear 96 pushes the first gear 97, and the first gear 97 pushes the second gear 98. In this process, the first bevel gear 99 on the side of the first gear 97 and the second gear 98 will push the second bevel gear 910, so as to achieve the purpose of driving the first stirring rod 93 and the second stirring rod 94, and the second gear 98 will not contact the connecting gear 96, and there will be no obstruction to rotation.

[0046] The method of use and working principle of the device: when in use, first clean and disinfect the fermentation box 1, remove the sealing cover 2 on the top of the fermentation box 1, put the liquid culture medium into the fermentation box 1, and then put the strain into the culture medium, and control the inoculation amount to 5% to 10%. Set the fermentation temperature according to the needs of the user, and connect the ventilation pipe 3 with the external oxygen production equipment to continuously add oxygen to the fermentation box 1. The injected oxygen will pass through the through hole 8 and contact the culture medium. If the dissolved oxygen is insufficient, use the stirring component 9 to stir the culture medium;

[0047] The power source of the stirring component 9 is provided by the driving component 6. The terminal of the servo motor 61 in the driving component 6 is connected to the external power supply. The servo motor 61 drives the transmission rod 69 through the belt transmission component 62, and the transmission rod 69 is used to push the semicircular frame 67 to achieve the purpose of driving the movable block 64 up and down. When the movable block 64 moves up, the stirring component 9 will be taken away from the culture medium through the vertical rod 66. When the movable block 64 moves downward, the stirring component 9 will be reinserted into the culture medium. This process is mainly to allow the stirring component 9 to create more openings in the culture medium to allow oxygen to enter.

[0048] During the up and down movement of the stirring assembly 9, the toothed plate 10 pushes the external gear 95, and the external gear 95 pushes the first gear 97 through the connecting gear 96 in the gear box 91, and the first gear 97 pushes the second gear 98. During this process, the first bevel gear 99 on the side of the first gear 97 and the second gear 98 will push the second bevel gear 910 to achieve the purpose of driving the first stirring rod 93 and the second stirring rod 94, and the first stirring rod 93 and the second stirring rod 94 are arranged obliquely and staggered. During the fermentation process, the rotation of the first stirring rod 93 and the second stirring rod 94 can stir the culture medium and make the culture medium with higher viscosity flow, and in this process, the stirring blades continuously separate from the liquid surface of the culture medium and then enter the culture medium. During this process, the stirring blades will draw an opening in the culture medium, and oxygen can enter the interior of the culture medium from the opening and dissolve into the culture medium.

[0049] When the mycelium growth in the culture medium reaches a predetermined density, the fermentation is terminated and the fermented edible fungi are taken out from the discharge chamber 4 .
