Description

Technical Field

[0001] This utility model relates to the field of edible fungi cultivation mixing technology, and in particular to a fungi culture medium mixing device. Background Technology

[0002] The edible mushroom industry is a quick and profitable rural economic development project that integrates economic, ecological, and social benefits. Currently, most of it is cultivated and propagated artificially. At present, the mixing of raw materials for the mushroom spawn culture medium is mainly done manually using hand tools. Because the raw materials consist of agricultural and forestry by-products, some wild materials rich in lignocellulose, and water, the mixture becomes viscous during manual mixing, preventing thorough mixing and making it difficult to package and shape the mixture.

[0003] A search revealed a utility model patent document with publication number CN219042500U, which discloses a mixing device for edible fungi cultivation. The device includes a second support platform, with a mixing cylinder bolted to the center of the top of the platform. A transmission shaft is movably connected to the center of the bottom inner wall of the mixing cylinder via a bearing. The beneficial effects of this utility model are that the transmission shaft drives the mixing blades to stir the edible fungi culture medium inside the mixing cylinder. The mixing blades can also drive a scraper to rotate against the inner wall of the mixing cylinder, effectively preventing the edible fungi culture medium from adhering to the inner wall and causing difficulty in cleaning. A second motor drives a conveying auger to rotate inside the unloading cylinder, transporting the evenly mixed edible fungi culture medium from the inlet trough to the unloading cylinder and discharging it through the outlet pipe, thus facilitating the bagging of the edible fungi culture medium.

[0004] In the process of mixing the above-mentioned mixing device, the inoculum material is directly mixed with water and then stirred. Since the inoculum material is composed of a variety of materials, directly mixing it with water without pre-mixing will result in uneven mixing of the various auxiliary materials of the inoculum material with the water, leading to poor mixing effect of the inoculum material.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] Please see Figure 1-8 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0031] A microbial culture medium mixing device includes a mixing frame 1, a pretreatment mixing frame 2 fixedly installed near the upper opening of the mixing frame 1, a discharge frame 3 installed below the mixing frame 1, a first mixing component installed in the pretreatment mixing frame 2, a second mixing component installed in the mixing frame 1, water adding components symmetrically installed on the front and rear sides of the mixing frame 1, a screw feeder 31 for discharging is rotatably installed in the discharge frame 3, a drive motor 32 with an output shaft fixedly installed on the left side of the discharge frame 3 and a downward-facing feeding frame 5 is fixedly installed on the right side of the discharge frame 3, the discharge frame 3 and the feeding frame 5 are connected, and the screw feeder 31 extends into the feeding frame 5;

[0032] A first discharge valve is provided below the pretreatment mixing frame 2. After the first discharge valve is opened, the pretreatment mixing frame 2 is connected to the mixing frame 1.

[0033] A second discharge valve assembly is provided below the mixing and stirring frame 1. When the second discharge valve is opened, the mixing and stirring frame 1 is connected to the discharge frame 3 below.

[0034] After being stirred by the first stirring component, the inoculum material enters the stirring chamber of the mixing frame 1 below through the first discharge valve. Then, the water adding component adds water to the mixing frame 1 for wet mixing. After being stirred by the second stirring component in the mixing frame 1, the inoculum material enters the discharge frame 3 below through the second discharge valve, is conveyed by the screw feeder 31, and is discharged through the discharge frame 5.

[0035] Specifically, the pretreatment mixing frame 2 first mixes the inoculum material, and after mixing, it enters the mixing frame 1. Then, water is added to the mixing frame 1 through the water addition component for further mixing. This mixing sequence can pre-crush large particles of auxiliary materials in the inoculum material in the pretreatment mixing frame 2, making the particle size of the inoculum material more uniform and improving the uniformity of subsequent wet mixing in the mixing frame 1.

[0036] In this embodiment, the first stirring component includes a second rotating shaft 8, which is rotatably disposed in the pretreatment stirring frame 2. A stirring cage 82 is fixedly disposed on the circumferential surface of the second rotating shaft 8. The rotation of the second rotating shaft 8 drives the stirring cage 82 to rotate, thereby stirring the bacterial raw materials in the pretreatment stirring frame 2.

[0037] In this embodiment, the first discharge valve includes symmetrically arranged arc-shaped plates 22. The two arc-shaped plates 22 can be merged after rotation. Horizontal support plates 21 are fixedly arranged on both outer sides of the pretreatment mixing frame 2. The arc-shaped plates 22 are arranged below the support plates 21. Support shafts 222 are symmetrically fixed between the left and right sides of the pretreatment frame. The arc-shaped plates 22 are rotatably arranged on the circumferential surface of the support shafts 222.

[0038] The outer side of the arc plate 22 is linearly fixed with several support plates 221. A telescopic cylinder 23 is provided between the support plate 221 and the support plate 21. The fixed end of the telescopic cylinder 23 is hinged to the support plate 21, and the movable end of the telescopic cylinder 23 is hinged to the support plate 221. Driven by the telescopic cylinder 23, the arc plate 22 can move in a circle around the support shaft 222, so as to put the inoculum material in the pretreatment mixing frame 2 into the mixing frame 1.

[0039] In this invention, the second stirring assembly includes a rotating shaft 7, a spiral stirring blade 73, and symmetrically arranged L-shaped stirring rods 75. Several stirring rods 72 are fixedly arranged on the circumferential surface of the rotating shaft 7. The spiral stirring blade 73 is sleeved on the surface of the rotating shaft 7 and fixed to the stirring rods 72. Connecting sleeves 74 are symmetrically fixedly arranged on the surfaces of the rotating shaft 7 near both ends. Two L-shaped stirring rods 75 are symmetrically fixedly arranged on the circumferential surfaces of the two connecting sleeves 74. The rotating shaft 7 drives the stirring rods 72, the spiral stirring blade 73, and the L-shaped stirring rods 75 to rotate synchronously, thereby stirring the inoculum material in the mixing frame 1.

[0040] In this embodiment, a groove 751 is provided on the outer side of the L-shaped stirring rod 75. A scraper 76 is slidably arranged in the groove 751. Several springs 752 are fixedly connected between the scraper 76 and the inner bottom surface of the groove 751. The scraper 76 is used to clean the inner wall of the mixing frame 1 to prevent the inoculum from adhering to the inner wall of the mixing frame 1 during the mixing process, thus affecting the mixing effect.

[0041] In this embodiment, the water supply component includes a water spray frame 6 fixedly disposed on the outer side of the mixing frame 1. The water spray frame 6 is fixedly disposed on the inclined surface of the inner cavity of the mixing frame 1 with a plurality of nozzles 62 communicating with the water spray frame 6. The water inlet pipe 61 communicating with the water spray frame 6 is fixedly disposed on the outer end face of the water spray frame 6. The outer end of the water inlet pipe 61 is connected to the water inlet mechanism. Water is supplied to the water spray frame 6 through the water inlet mechanism, and then water is sprayed into the mixing frame 1 through the nozzles 62.

[0042] The above-mentioned nozzle 62 and water inlet mechanism are existing technologies and will not be drawn or described in detail here.

[0043] Specifically, the symmetrically arranged water spray frame 6 and several linearly arranged nozzles 62 can evenly spray water onto the inoculum material in the mixing frame 1, improving the uniformity of wet mixing.

[0044] In this embodiment, a drive motor 15 is fixedly installed on the left side of the mixing frame 1. The output shaft of the drive motor 15 is fixed to one end of the rotating shaft 7. Rotating shaft 7 and rotating shaft 8 are respectively fixedly installed on the circumferential surface of the right side of the mixing frame 1, with a transmission belt 9 connecting them. The drive motor 15 drives the rotating shaft 7 to rotate, and then the transmission belt 9 drives the rotating shaft 8 to rotate synchronously.

[0045] In this embodiment, the second discharge valve includes a rotating shaft 11. A closed block 12 with a fan-shaped cross-section is fixedly arranged on the circumferential surface of the rotating shaft 11. A discharge port 13 is opened on the lower surface of the mixing frame 1, and ear plates 14 are symmetrically fixedly arranged on the lower end face of the mixing frame 1. The rotating shaft 11 is rotatably arranged between the two ear plates 14. A second drive motor 16 is fixedly arranged on the outer side of the left ear plate 14. The output shaft of the second drive motor 16 is fixed to one end of the rotating shaft 11. The position of the closed block 12 corresponds to the position of the discharge port 13.

[0046] The arc-shaped surface of the sealing block 12 can seal the discharge port 13, and when the scraper 76 moves to the position of the sealing block 12, the scraper 76 will retract into the groove 751, which will not affect the cleaning of the inner wall of the mixing frame 1 by the scraper 76.

[0047] Specifically, after the inoculum material in the mixing frame 1 is mixed, the drive motor 2 16 drives the rotating shaft 11 to rotate 180°, which causes the sealing block 12 to release the seal on the discharge port 13, so that the mixed inoculum material enters the discharge frame 3 below.
