[0005] In view of the shortcomings of the existing technology, the present invention provides a microbial substrate stirring and mixing device, which solves the problem of low substrate preparation efficiency in the existing technology.

[0006] According to an embodiment of the present invention, a microbial substrate mixing device includes a frame and a mixing box disposed on the frame. The mixing box is provided with a first mixing chamber and a second mixing chamber spaced apart. The first mixing chamber and the second mixing chamber are respectively provided with rotatable mixing shafts. The mixing box is provided with drive assemblies that are respectively connected to the two mixing shafts. The mixing box is also provided with a connecting pipe and a first conveying assembly. One end of the connecting pipe is connected to the first mixing chamber and the other end is connected to the second mixing chamber. The first conveying assembly includes a first conveying motor and a first conveying shaft disposed at the output end of the first conveying motor. The first conveying shaft is rotatably disposed on the connecting pipe and extends into the connecting pipe. The portion of the first conveying shaft located inside the connecting pipe is provided with a first spiral blade.

[0007] Furthermore, the stirring shaft is provided with a plurality of spiral stirring blades, which are spaced apart circumferentially along the stirring shaft.

[0008] Furthermore, a plurality of collars are provided at intervals along the axial direction of the stirring shaft, and a plurality of straight stirring blades are provided on each collar, with the straight stirring blades being spaced apart circumferentially along the stirring shaft.

[0009] Furthermore, scrapers are fixedly connected to the straight stirring blades, and the scrapers are located at the end of the straight stirring blades away from the collar.

[0010] Furthermore, the drive assembly includes a drive motor and a drive shaft disposed at the output end of the drive motor. A first bevel gear is sleeved on the drive shaft, and a second bevel gear is sleeved on the stirring shaft, with the second bevel gear meshing with the first bevel gear.

[0011] Furthermore, the mixing tank is also provided with a mounting frame, which is located between the first mixing chamber and the second mixing chamber, and the first bevel gear and the second bevel gear are respectively rotatably connected to the mounting frame.

[0012] Furthermore, the angle between the axial direction and the horizontal direction of the connecting pipe is an acute angle, and the height of the end of the connecting pipe connected to the first stirring chamber is lower than the height of the end of the connecting pipe connected to the second stirring chamber.

[0013] Furthermore, the mixing tank is also provided with a discharge pipe and a second conveying assembly.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a fungal substrate mixing device, which is used to mix materials such as sawdust, wheat bran, and straw with nutrients to form a culture substrate for subsequent fungal inoculation during the production of edible fungi.

[0023] Please refer to Figure 1 and Figure 2 The microbial substrate mixing device includes a frame 1 and a mixing tank 2 mounted on the frame 1. The mixing tank 2 has a first mixing chamber 21 and a second mixing chamber 22 spaced apart. Each of the first mixing chamber 21 and the second mixing chamber 22 has a rotatable mixing shaft 3. The mixing tank 2 is equipped with drive components 4 that are respectively connected to the two mixing shafts 3. The drive components 4 drive the mixing shafts 3 to rotate, thus mixing the materials in the first mixing chamber 21 and the second mixing chamber 22. The mixing tank 2 also has a connecting pipe 23 and a first conveying component 5. One end of the connecting pipe 23... One end of the first conveying assembly 5 is connected to the first stirring chamber 21, and the other end is connected to the second stirring chamber 22. The first conveying assembly 5 includes a first conveying motor 51 and a first conveying shaft 52 disposed at the output end of the first conveying motor 51. The first conveying shaft 52 is rotatably disposed on the connecting pipe 23 and extends into the connecting pipe 23. The portion of the first conveying shaft 52 located inside the connecting pipe 23 is provided with a first spiral blade 53. After the first conveying motor 51 is started, it drives the first conveying shaft 52 to rotate and drives the first spiral blade 53 to rotate, thereby inputting the material in the first stirring chamber 21 into the second stirring chamber 22.

[0024] Specifically, the operation steps for preparing the substrate using the microbial substrate mixing device provided in this embodiment are as follows: Materials are added to the first mixing chamber 21 in a specified ratio. After the materials are added, the drive assembly 4 is activated to drive the stirring shaft 3 to rotate. The stirring shaft 3 rotates to mix the materials in the first mixing chamber 21. After the materials in the first mixing chamber 21 have been mixed to a certain extent, the first conveying motor 51 is activated. The first conveying motor 51 drives the first conveying shaft 52 to rotate and rotates the first spiral blade 53 to transport the materials in the first mixing chamber 21 along the connecting pipe 23 to the second mixing chamber 22. At this time, the stirring shaft 3 in the second mixing chamber 22 rotates under the drive assembly 4 and performs secondary mixing of the materials to ensure uniform mixing. Furthermore, during the mixing process in the second mixing chamber 22, materials can be added back to the first mixing chamber 21 while simultaneously being stirred, thereby increasing the amount of substrate that can be prepared per unit time. The substrate mixing device provided in this embodiment ensures uniform mixing of materials by performing secondary mixing. While the materials are being mixed in the second mixing chamber 22, other materials can also be mixed in the first mixing chamber 21. This improves the substrate preparation efficiency and allows for the preparation of more substrate per unit time, meeting the needs of edible fungi production.

[0025] like Figure 2 and Figure 3As shown, the stirring shaft 3 is provided with a plurality of spiral stirring blades 31, which are spaced apart circumferentially along the stirring shaft 3. When the stirring shaft 3 rotates under the drive assembly 4, the spiral stirring blades 31 rotate in the first stirring chamber 21 or the second stirring chamber 22 as the stirring shaft 3 rotates, and agitate the material in the first stirring chamber 21 or the second stirring chamber 22, thereby accelerating the mixing of the material in the first stirring chamber 21 or the second stirring chamber 22.

[0026] Please combine Figure 2 and Figure 3 The stirring shaft 3 has multiple collars 32 spaced apart along its axial direction. Each collar 32 has multiple straight stirring blades 33 spaced apart circumferentially along the stirring shaft 3. When the stirring shaft 3 rotates, it drives the straight stirring blades 33 to rotate, thereby agitating the material in the first stirring chamber 21 or the second stirring chamber 22. This further improves the stirring effect of the stirring shaft 3 and facilitates rapid and uniform mixing of the material in the first stirring chamber 21 or the second stirring chamber 22.

[0027] In detail, scrapers 34 are fixedly connected to the straight stirring blades 33, and the scrapers 34 are located at the end of the straight stirring blades 33 away from the collar 32. The scrapers 34 provided at the end of the straight stirring blades 33 are used to scrape off the material adhering to the inner wall of the first stirring chamber 21 or the second stirring chamber 22, so as to avoid material loss caused by material adhering to the inner wall of the first stirring chamber 21 or the second stirring chamber 22.

[0028] Please refer to Figure 2 The driving assembly 4 includes a driving motor 41 and a driving shaft 42 disposed at the output end of the driving motor 41. A first bevel gear 43 is sleeved on the driving shaft 42, and a second bevel gear 35 is sleeved on the stirring shaft 3, with the second bevel gear 35 meshing with the first bevel gear 43. The driving motor 41 drives the driving shaft 42 to rotate, which in turn drives the first bevel gear 43 to rotate. Through the engagement of the first bevel gear 43 and the second bevel gear 35, the power output by the driving motor 41 is transmitted to the stirring shaft 3, causing the stirring shaft 3 to rotate. The two stirring shafts 3 rotate in opposite directions under the drive of the driving assembly 4, so that the direction in which the material is stirred in the first stirring chamber 21 is opposite to the direction in which the material is stirred in the second stirring chamber 22. This helps to improve the uniformity of material mixing and avoids uneven mixing caused by the material being stirred in a single direction.

[0029] In this embodiment, the mixing tank 2 is further provided with a mounting bracket 24. The mounting bracket 24 is located between the first mixing chamber 21 and the second mixing chamber 22, and the first bevel gear 43 and the second bevel gear 35 are respectively rotatably connected to the mounting bracket 24. The mounting bracket 24 provided on the mixing tank 2 is used to install the first bevel gear 43 and the second bevel gear 35, and to ensure the stable engagement between the first bevel gear 43 and the second bevel gear 35, thereby improving the structural stability of the microbial substrate mixing device.

[0030] like Figure 1 and Figure 2 As shown, the angle between the axial direction and the horizontal direction of the connecting pipe 23 is an acute angle, and the height of the end of the connecting pipe 23 connected to the first stirring chamber 21 is lower than the height of the end of the connecting pipe 23 connected to the second stirring chamber 22. The connecting pipe 23 is inclined on the mixing tank 2, and the connection point of the connecting pipe 23 and the first stirring chamber 21 is located at the bottom of the first stirring chamber 21. This allows the material in the first stirring chamber 21 to fall into the connecting pipe 23 under the action of gravity and then be smoothly fed into the second stirring chamber 22 by the first conveying component 5. At the same time, it prevents the material from sliding into the second stirring chamber 22 when the first conveying component 5 is not turned on, ensuring the stable operation of the microbial substrate mixing device.

[0031] Please combine Figure 1 and Figure 2 The mixing tank 2 is also equipped with a discharge pipe 25 and a second conveying assembly 6. The discharge pipe 25 is connected to the second mixing chamber 22 and extends away from the mixing tank 2. The second conveying assembly 6 includes a second conveying motor 61 and a second conveying shaft 62 disposed at the output end of the second conveying motor 61. The second conveying shaft 62 is rotatably disposed on the discharge pipe 25 and extends into the discharge pipe 25. A second spiral blade 63 is provided on the portion of the second conveying shaft 62 located inside the discharge pipe 25. The discharge pipe 25 is used to discharge the mixed material in the second mixing chamber 22 out of the mixing tank 2. When it is necessary to discharge the material in the second mixing chamber 22, the second conveying motor 61 is turned on to drive the second conveying shaft 62 to rotate. The second conveying shaft 62 drives the second spiral blade 63 to rotate to convey the material in the second mixing chamber 22 along the discharge pipe 25, thereby stably discharging the mixed material in the mixing tank 2.

[0032] Specifically, the angle between the axial direction and the horizontal direction of the discharge pipe 25 is an acute angle, and the height of the end of the discharge pipe 25 connected to the second mixing chamber 22 is lower than the height of the end of the discharge pipe 25 away from the mixing tank 2. The discharge pipe 25 is inclinedly arranged on the mixing tank 2, and the connection between the discharge pipe 25 and the second mixing chamber is located at the bottom of the second mixing chamber 22, so that the material in the second mixing chamber 22 can fall into the discharge pipe 25 under the action of gravity. This ensures that the material in the second mixing chamber 22 can be smoothly discharged from the mixing tank 2 when the second conveying component 6 is turned on, while preventing the material from falling out of the second mixing chamber 22 along the discharge pipe 25 when the second conveying component 6 is not turned on.

[0033] like Figure 2 As shown, a guide pipe 26 is provided at the end of the discharge pipe 25 away from the mixing tank 2, and the axial direction of the guide pipe 26 is perpendicular to the axial direction of the discharge pipe 25. The guide pipe 26, located at the end of the discharge pipe 25, is used to guide the material discharged from the discharge pipe 25 to a designated position, facilitating the transfer of the mixed material to the next process.
