[0025] A method for using a fermentation tank for cultivating shiitake mushroom strains comprises the following steps:

[0026] S1, stirring the bacterial raw materials, adding the bacterial raw materials into the tank through the top cover of the tank, starting the driving motor to drive the main shaft to rotate, and the main shaft drives the stirring blade body to stir the bacterial raw materials;

[0027] S2. Unlock the positioning block. When the foldable stirring frame needs to be disassembled, first discharge the bacterial strain material inside the tank body, then open the tank cover, press the button to drive the control main rod to descend, and the control main rod descends to drive the driving block to descend, and the driving block drives the connecting plate to descend and enter the inclined position of the driving groove. Along the trajectory of the driving groove, the connecting plate pulls the compression spring of the positioning block back, and at the same time, the slot inside the positioning block disengages from the positioning protrusion and the connecting plate enters the inside of the turnover groove, so that the stirring blade body is free from the restriction, and the stirring blade body can be driven by the control mechanism to be stored;

[0028] S3, driving the upward flipping driving frame, when the positioning block is out of the limit of the positioning protrusion, pressing button 2 drives the stabilizing bar to descend, because the two upward flipping driving frames are fixedly connected by the stabilizing bar, when the stabilizing bar descends, the two upward flipping driving frames will descend together, the rack in the upward flipping driving frame descends and meshes with gear 2, and gear 2 is connected to gear 1 through gear 3 and a transmission member on one side, so that gear 1 drives the rotating shaft and the stirring blade body to perform an upward flipping movement, so that the stirring blade bodies in the stirring blade group 1 at the bottom and the stirring blade group 2 at the bottom perform an upward flipping movement at the same time;

When the stabilizing bar is descending, the latch gear group 1 on the stabilizing bar meshes with the circulating gear, and the circulating gear rotates and meshes with the latch gear group 2, so that the latch gear group 2 drives the linkage rod to rise. When the linkage rod rises, it drives the transmission tooth to mesh with gear 2. Gear 2 is rotationally connected with gear 1 through gear 3 and the transmission member on one side thereof. Gear 1 drives the rotating shaft and the stirring blade body to flip downward, so that the stirring blade group 1 at the top and the stirring blade groups 2 at the top and the middle position move downward.

[0030] S5. Take out the foldable stirring frame. When the second push button is pressed down, turn the rotating plate to fit into the slot on the inner wall of the main shaft rod, and then pull the main shaft rod out from the top of the tank body.

[0031] Compared with the prior art, the present invention provides a fermentation tank for cultivating shiitake mushroom strains and a method of using the same, which has the following beneficial effects:

[0032] 1. The fermenter for cultivating Lentinula edodes strains and its usage method. By setting the stirrer frame and the tank body during folding, compared with the common Lentinula edodes strain fermenters on the market, the stirrer group one and the stirrer group two can be folded by pressing the button one and the button two, and the main shaft rod can be pulled out from the inside of the tank body. The operation method is simple and fast, and the stirrer group one and the stirrer group two can be fully cleaned, ensuring the fermentation quality of the strain raw materials.

[0033] 2. The fermenter for cultivating Lentinula edodes strains and its usage method.

Specific Embodiments

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] Please refer to Figures 1 - 15 , a fermentation tank for cultivating Lentinula edodes strains and its usage method, including:

[0052] A foldable stirring rack 1 for stirring strain raw materials. The foldable stirring rack 1 includes a main shaft rod 11, and a first stirring group 12 and a second stirring group 13 sequentially arranged on the main shaft rod 11. The first stirring group 12 includes not less than two groups of first stirring blade groups 14. The first stirring blade group 14 includes a stirring blade main body 141 fixedly installed on a circle of the main shaft rod 11 and a connecting plate 143. A heating sheet 142 is arranged inside the stirring blade main body 141. A positioning protrusion 144 is arranged at one end of the stirring blade main body 141. A hinge seat rotatably connected to one end of the stirring blade main body 141 is arranged on one side of the connecting plate 143. Stirring blade reset components are arranged on both sides of the inner wall of the hinge seat. A rotating shaft 1412 is fixedly arranged inside one end of the stirring blade main body 141.

[0053] A fixing block 15 is fixedly arranged inside the main shaft rod 11. Not less than one control cavity 151 and a transmission cavity 152 communicating with the control cavity 151 are opened inside the fixing block 15. The transmission cavity 152 is arranged opposite to the connecting plate 143. A control main rod 16 passing through the inside of the fixing block 15 is movably arranged inside the main shaft rod 11. Driving blocks 161 with one end extending into the control cavity 151 and not less than one are arranged on the control main rod 16. A positioning block 17 with one end penetrating to the outside of the connecting plate 143 is movably arranged inside the transmission cavity 152. The end of the positioning block 17 away from the transmission cavity 152 is arc-shaped and provided with a slot 171 inserted with the positioning protrusion 144. A driving groove 172 is opened on one side of the positioning block 17. A connecting plate 162 with one end extending into the driving groove 172 is fixedly arranged at one end of the driving block 161;

[0054] The main shaft 11 is provided with an upward turning driving frame 18 and a downward turning driving frame 19 which is connected to the upward turning driving frame 18 by transmission. The upward turning driving frame 18 and the downward turning driving frame 19 are used to drive two groups of stirring blades 14 respectively. The upward turning driving frame 18, the downward turning driving frame 19, the gear 1 1413 and the gear 2 146 constitute a control mechanism.

[0055] The tank body 2 is used to cooperate with the foldable stirring frame 1 to stir the mushroom spawn. A driving motor is arranged at the bottom of the tank body 2, and the output end of the motor extends to the interior of the tank body 2 and is transmission-connected to the bottom of the main shaft rod 11. The tank body 2 has an outer shape of a combination of large and small circles. The bottom of the main shaft rod 11 is provided with a slot matching the output end of the driving motor, which can be directly plugged into the output end of the driving motor.

[0056] As a specific technical solution of this embodiment, the stirring group 2 13 includes no less than two stirring blade groups 2, and the stirring blade group 2 has the same structure as the stirring blade group 1 14, but the stirring blade body 141 in the stirring blade group 1 14 is longer than the stirring blade body 141 in the stirring blade group 2;

[0057] The number of the stirring blade groups 14 is two, the stirring blade bodies 141 in the two stirring blade groups 14 are staggered and the two stirring blade groups 14 are driven by the control mechanism to perform flipping motion towards or away from each other, and the distance between the two stirring blade groups is consistent with the length of the stirring blade assembly inside them;

[0058] The number of the stirring blade groups 2 is three, the top and bottom stirring blade groups 2 are arranged opposite to each other, and the stirring blade groups 2 in the middle are staggered with the top and bottom stirring blade groups 2, and the top and bottom stirring blade groups 2 are driven by the control mechanism to perform flipping motion towards each other or flipping motion away from each other;

[0059] The three groups of stirring blades are arranged on the main shaft 11 at equal intervals, and the distance between two adjacent groups of stirring blades is consistent with the length of the stirring blade body 141 inside them. Figure 3The two groups of stirring blade groups 14 are driven by the upward turning driving frame 18 and the downward turning driving frame 19 respectively. The stirring blade group 14 at the bottom is close to the bottom of the inner wall of the large circle of the tank body 2, so it is driven by the upward turning driving frame 18. If it is driven by the downward turning driving frame 19, the stirring blade group 14 at the bottom will hit the bottom of the inner wall of the tank body 2. The stirring blade group 14 at the top is close to the top of the inner wall of the large circle of the tank body 2, so it is driven by the downward turning driving frame 19. If it is driven by the upward turning driving frame 18, the stirring blade group 14 at the top will conflict with the top of the inner wall of the large circle of the tank body 2. The upward turning driving frame 18 and the downward turning driving frame 19 can make the two groups of stirring blade groups 14 perform opposite turning movements and opposite turning movements. At the same time, the two groups of stirring blade groups 14 can be respectively located at the bottom and top of the large circle of the tank body 2 after being unfolded, so as to fully stir the bacterial strain raw materials inside the large circle of the tank body 2.

[0060] See also Figure 1 and Figure 3 Since the length of the small circle of the tank body 2 is greater than the large circle of the tank body 2, the number of the stirring blade group 2 is greater than the number of the stirring blade group 1 14. The number of the stirring blade group 2 is three. In order to enable the stirring blade group 2 to fully stir the bacterial strain raw material inside the small circle of the tank body 2, the top and bottom stirring blade groups 2 and the two stirring blade groups 14 adopt the same driving principle. Since the distance between the two adjacent groups of the stirring blade groups 2 is consistent with the length of the stirring blade body 141 inside them, the stirring blade group 2 located in the middle position can adopt the upward turning drive frame 18 or the downward turning drive frame 19, which will not affect the stirring of the bacterial strain raw material. The number of the stirring blade group 1 14 and the stirring blade group 2 is mainly determined by the length of the large circle and the small circle of the tank body 2, and is not limited to two and three.

[0061] As a specific technical solution of this embodiment, the number of the upward-turning driving frames 18 is at least two and they are respectively connected to the bottom stirring blade group 1 14 and the bottom stirring blade group 2 in transmission connection, and the number of the downward-turning driving frames 19 is at least three and they are respectively connected to the top stirring blade group 1 14, the top stirring blade group 2 and the stirring blade group 2 located in the middle position in transmission connection;

[0062] The flip-up driving frame 18 includes a rack 181 meshing with one of the gears 146, and a stabilizing plate 183 and a stabilizing bar 182 disposed on the top of the rack 181. The number of the rack 181 is not less than one, and two adjacent flip-up driving frames 18 are fixedly connected by the stabilizing bar 182.

[0063] The downward flipping driving frame 19 includes a linkage rod 191, one end of which is provided with a transmission tooth 192 meshing with one of the gears 146, and two adjacent downward flipping driving frames 19 are fixedly connected by the linkage rod 191, see Figure 6The stabilizing bar 182 in the uppermost up-flipping driving frame 18 passes through the fixed block 15 and is connected to the stabilizing bar 182 in the lower up-flipping driving frame 18, so that the two up-flipping driving frames 18 can operate synchronously, please refer to 12 and 13. The linkage rod 191 in the uppermost down-flipping driving frame 19 passes through the fixed block 15 and is connected to the linkage rod 191 in the lower down-flipping driving frame 19.

[0064] As a specific technical solution of this embodiment, a connecting slot 111 is provided at the connection between the main shaft rod 11 and the connecting plate 143, and a sealing ring 112 is provided inside the connecting slot 111 to fit the outside of the connecting plate 143. The top and bottom of the connecting plate 143 are both provided with an edge plate, and the edge plate is fixedly connected to the main shaft rod 11 by screws.

[0065] A stabilizing platform 113 is fixedly provided on the inner wall of the main shaft rod 11, and the stabilizing platform 113 is movably sleeved with the surface of the linkage rod 191. A circulating gear 114 is rotatably provided inside the main shaft rod 11, and a latching tooth group 184 and a latching tooth group 2 193 that mesh with the circulating gear 114 are respectively provided between the stabilizing bar 182 and the linkage rod 191.

The top of the stabilizing bar 182 at the top extends to the outside of the main shaft rod 11 and is provided with a pressing button 2 185. A rotating plate 186 is rotatably provided on the top of the pressing button 2 185. A slot matching the rotating plate 186 is provided on the top of the inner wall of the main shaft rod 11, see Figure 6 , Figure 10 , Figure 12 as well as Figure 13 When the positioning block 17 is out of the limit of the positioning protrusion 144, the second button 185 is pressed to drive the stabilizing bar 182 to descend. Since the two upward-turning driving frames 18 are fixedly connected by the stabilizing bar 182, when the stabilizing bar 182 descends, the two upward-turning driving frames 18 will descend together, and the rack 181 in the upward-turning driving frame 18 will descend and mesh with the second gear 146. The second gear 146 is connected to the first gear 1413 through the third gear 147 and the transmission member on one side, so that the first gear 1413 drives the rotating shaft 1412 and the stirring blade body 141 to perform an upward movement. Figure 15, the stirring blade groups 14 at the bottom and the stirring blade main bodies 141 in the bottommost stirring blade group two perform upward turning movements simultaneously. With the setting of the circulating gear 114, when the stabilizing bar 182 descends, the first set of engaging teeth 184 on the stabilizing bar 182 meshes with the circulating gear 114, and the circulating gear 114 rotates and meshes with the second set of engaging teeth 193, causing the second set of engaging teeth 193 to drive the linkage rod 191 to rise. When the linkage rod 191 rises, it drives the transmission gear 192 to mesh with the second gear 146. The second gear 146 is rotationally connected to the first gear 1413 through the third gear 147 on one side thereof and a transmission member. The first gear 1413 drives the rotating shaft 1412 and the stirring blade main body 141 to perform downward turning movements. Refer to Figure 15 , the topmost stirring blade group 14 and the topmost and middle-position stirring blade groups two perform downward movements. Since the two stirring blade groups 14 are staggered from each other, and the three stirring blade groups two are also staggered from each other, it will not cause the situation that the multiple stirring blade main bodies 141 conflict with each other when being turned over and stored. Please continue to refer to Figure 15 , after the multiple stirring blade main bodies 141 are turned over and stored, their volume is reduced a lot, and they can be directly taken out from the outlet at the top of the tank body 2. Since the downward turning drive frame 19 is driven by the upward turning drive frame 18, the downward turning drive frame 19 does not need to be provided with a control structure, and it can be stably lifted and lowered through the stabilizing platform 113.

[0066] As a specific technical solution of this embodiment, the stirring blade reset assembly includes reset grooves 1451 opened on both sides of the inner wall of the connecting seat 145 and the paddles 1411 installed on both sides of one end of the stirring blade main body 141. The reset grooves 1451 are arranged in a C shape. Two sets of compression springs 1452 are arranged inside the reset grooves 1451. One end of the paddle 1411 away from the stirring blade main body 141 extends into the reset grooves 1451 and is located between the two sets of compression springs 1452. A spring 1521 with one end connected to one side of the positioning block 17 is arranged inside the transmission cavity 152. A turnover groove 153 is also opened on one side of the inner wall of the control cavity 151 for accommodating the connecting plate 162 in the descending state;

[0067] The upper and middle parts of the driving groove 172 are vertical, and the lower and middle parts are inclined, so that when the driving block 161 drives the connecting plate 162 to descend, the connecting plate 162 slides inside the driving groove 172 to realize that the positioning block 17 is pulled by the connecting plate 162 to disengage from the connection with the positioning protrusion 144. The main purpose of the stirring blade reset assembly is to keep the stirring blade body 141 in place, so that the stirring blade body 141 can remain in place when it is not driven by the control mechanism. When the gear 1413 drives the rotating shaft 1412 to rotate, the rotating shaft 1412 drives one end of the stirring blade body 141 to rotate, and the stirring blade body 141 drives the paddle 1411 to compress the compression spring 1452 on one side thereof. This design scheme enables the compressed compression spring 1452 to rebound and resist the paddle 1411 when the gear 1413 is out of the driving state, so that the paddle 1411 drives the stirring blade body 141 to reset, see Figure 6 and 7 A driving groove 172 is provided on one side of the positioning block 17. When the push button 164 is pressed, the main rod 16 is controlled to descend and drive the driving block 161 to descend. The driving block 161 drives the connecting plate 162 to descend and enter the inclined position of the driving groove 172. Along the trajectory of the driving groove 172, the connecting plate 162 pulls the compression spring 1521 of the positioning block 17 to retreat. At the same time, the slot 171 inside the positioning block 17 is separated from the positioning protrusion 144 and the connecting plate 162 enters the inside of the turnover groove 153, so that the stirring blade body 141 is free from the restriction, and the stirring blade body 141 can be driven by the control mechanism to be stored. When the push button 185 is pressed, When the driving control mechanism drives the stirring blade body 141 to rotate, the stirring blade body 141 drives the positioning protrusion 144 to disengage from the slot 171 and conflict with the arc on one side of the positioning block 17, so that the positioning block 17 cannot be reset. At this time, there is no need to press button 164 and the arc angle on one side of the positioning block 17 is large, so that when the stirring blade body 141 flips over and conflicts with the main shaft rod 11, the positioning protrusion 144 thereon will not disengage from the arc on the positioning block 17. This design scheme makes it possible to directly operate button 2 185 without operating button 164 when the stirring blade body 141 is reset horizontally in the later stage.

[0068] As a specific technical solution of this embodiment, the heating plate 142 is in a mountain shape, and the top and bottom of both sides of the stirring blade body 141 are both arranged in an arc shape. An elastic wire 1421 connected to the internal heating plate 142 is arranged on one end of the stirring blade body 141, and the end of the elastic wire 1421 away from the stirring blade body 141 passes through the connecting plate 143 and extends to the inside of the main shaft rod 11 and is provided with a conductive plug 1422. The inner wall of the main shaft rod 11 is fixedly provided with a conductive plug 1422 connected to the stirring blade body 141. The elastic wire 1421 is electrically connected to the power supply cable through the conductive plug 1422. The top of the fixed block 15 is fixedly provided with a wire harness enclosure 156 for shielding the elastic wire 1421. The bottom of one side of the wire harness enclosure 156 is provided with an elastic rope 157 with one end connected to the elastic wire 1421. The mountain-shaped heating plate 142 is covered with the top, middle and bottom of the stirring blade body 141, which can fully heat the stirring blade body 141, so that the stirring blade body 141 can heat the stirring blade body 141. The bacterial strain raw material inside the tank body 2 is heated. Compared with the conventional bottom heating method, the bacterial strain raw material can reach the set temperature more quickly by heating the stirring blade body 141 and the inner wall of the tank body 2, thereby ensuring the raw material fermentation efficiency and more uniform heating. The arc-shaped settings of the top and bottom on both sides of the stirring blade body 141 reduce resistance, making the rotation of the stirring blade body 141 more labor-saving. The setting of the elastic wire 1421 can be unaffected by the bending of the stirring blade body 141 and can still provide stable power supply. The elastic wire 1421 is connected to the power supply cable inside the main shaft rod 11 through the conductive plug 1422, which facilitates the independent disassembly of the connecting plate 143 at a later time, further ensuring the usability of the device. The elastic rope 157 can pull the elastic wire 1421. When the connecting plate 143 is connected to the main shaft rod 11, the elastic rope 157 resets and pulls the elastic wire 1421 close to the wire harness enclosure 156, thereby avoiding the elastic wire 1421 from shaking around and getting entangled inside the main shaft rod 11.

[0069] As a specific technical solution of this embodiment, a protective cover 1432 is provided on one side of the connecting plate 143, and the interior of the protective cover 1432 is fixedly sleeved with the surface of one end of the stirring blade body 141, and a gear three 147 with a diameter smaller than that of the gear two 146 is provided on one side of the gear two 146, and the gear three 147 is connected to the gear one 1413 through a transmission member, and a slide groove 154 and a stabilizing groove 155 located on one side of the slide groove 154 are provided inside the fixed block 15, and the rack 181 is movably arranged inside the slide groove 154, and one end of the stabilizing bar 182 is fixedly connected to the top end of the rack 181, and the other end passes through the interior of the stabilizing groove 155 and is fixedly connected to the stabilizing plate 183 in the other flip-up driving frame 18, so as to realize the transmission connection between the two flip-up driving frames 18;

[0070] A linkage groove 158 is further formed inside the fixed block 15. One end of the linkage rod 191, which is provided with a transmission gear 192, extends into the linkage groove 158, and the other end is bent in a U shape and then penetrates through the fixed block 15 again and is fixedly connected to the linkage rod 191 in another downward turning drive frame 19, so as to realize the transmission connection of the three downward turning drive frames 19. The protective cover 1432 is made of rubber to protect the connection seat 145 from being eroded by the strain material. The third gear 147 is used for the transmission between the second gear 146 and the first gear 1413. The transmission member can adopt a chain and a transmission belt 192. The chute 154 and the stable groove 155 are formed for passing through the rack 181 and the stable bar 182 respectively. The linkage groove 158 is arranged in a U shape for passing through the linkage rod 191.

[0071] As a specific technical solution of this embodiment, a conductive slide plate 115 is arranged on the main shaft rod 11. A tension spring 159 is arranged on the top of the fixed block 15, and the inner part of the tension spring 159 sleeved on the surface of the control main rod 16. A pressing plate 163 is arranged on the surface of the control main rod 16 and located on the top of the tension spring 159. The surface of the tank body 2 is provided with at least one heating block 21. The outer shell of the tank body 2 is of a three-layer structure, and the three-layer structure includes a heat insulation layer 25, a metal heat conduction layer 26 and an anti-sticking layer 27. An electromagnet 23 magnetically connected to the heating block 21 is arranged on the heat insulation layer 25. The heating block 21 is internally provided with at least one heating head 24, and one end of the heating head 24 extends into the metal heat conduction layer 26. When pressing the first push button 164 to drive the control main rod 16 to descend, the pressing plate 163 on the control main rod 16 compresses the tension spring 159. The arrangement of the tension spring 159 enables the tension spring 159 to rebound and push up the pressing plate 163 when the user releases the first push button 164, so that the pressing plate 163 drives the control main rod 16 to rise and reset. When the control main rod 16 rises, it will drive the driving block 161, the connecting plate 162 and the positioning block 17 to reset. The heating head 24 adopts an electric heating tube or an electric heating plate. When the heating head 24 is started, the heating head 24 transfers heat to the metal heat conduction layer 26, and can quickly heat the strain material inside the tank body 2. The anti-sticking layer 27 adopts a common food anti-sticking coating on the market. The metal heat conduction layer 26 adopts a copper plate. The conductive slide plate 115 and the conductive slip ring 292. The conductive slip ring 292 is electrically connected to the power supply cable. The arrangement of the conductive slip ring 292 enables electrical conduction to be achieved after the conductive slide plate 115 contacts the conductive slip ring 292, without affecting the rotation of the main shaft rod 11, and at the same time, stable power supply can still be carried out.

[0072] As a specific technical solution of this embodiment, the tank body 2 is also provided with at least one observation window 28. The top of the tank body 2 is provided with a top cover 29. The bottom of the top cover 29 is provided with a pressing cylinder 291 with one end extending into the interior of the tank body 2. The top end of the main shaft rod 11 extends into the interior of the pressing cylinder 291. The bottom of the pressing cylinder 291 is movably connected with a conductive slip ring 292 through a bearing. The bottom of the conductive slip ring 292 is in contact with the top of the conductive slide plate 115. Through the observation window 28, the stirring condition of the strain raw materials inside the tank body 2 can be observed. Through the top cover 29, the strain raw materials can be added. The setting of the pressing cylinder 291 presses the conductive slide plate 115 through the conductive slip ring 292. The setting of the bearing enables the conductive slip ring 292 not to affect the rotation of the conductive slip ring 292. The inside of the pressing cylinder 291 is used to place the first push button 164 and the second push button 185. When disassembling the top cover 29, the folding stirring frame 1 can be disassembled. The top cover 29 and the top of the tank body 2 can be connected by threads or a buckle. The bottom of the tank body 2 is provided with a valve for discharging the strain raw materials. Through the valve, the fermented strain raw materials can be discharged.

The driving block 161 drives the connecting plate 162 to descend into the inclined position of the driving groove 172. Along the track of the driving groove 172, the connecting plate 162 pulls the positioning block 17 to compress the spring 1521 and retreat. At the same time, the slot 171 inside the positioning block 17 disengages from the positioning protrusion 144 and the connecting plate 162 enters the interior of the turnover groove 153, so that the stirring blade body 141 is released from the restriction, and then the stirring blade body 141 can be driven by the control mechanism to be retracted.

[0076] S3, drive the upward flip driving frame 18, when the positioning block 17 is out of the limit of the positioning protrusion 144, press the second button 185 to drive the stabilizing bar 182 to descend, because the two upward flip driving frames 18 are fixedly connected by the stabilizing bar 182, when the stabilizing bar 182 descends, the two upward flip driving frames 18 will descend together, and the rack 181 in the upward flip driving frame 18 will descend and mesh with the second gear 146, and the second gear 146 is connected to the first gear 1413 through the third gear 147 and the transmission member on one side, so that the first gear 1413 drives the rotating shaft 1412 and the stirring blade body 141 to perform an upward flipping movement, so that the stirring blade group 1 14 at the bottom and the stirring blade body 141 in the second stirring blade group at the bottom perform an upward flipping movement at the same time;
