The outer surface of the fermentation tank 1 close to the bottom is fixedly installed with a discharging pipe 22 in communication with the interior of the fermentation tank 1.

[0020] In use, the yellow mealworm nutrient material to be fermented is injected into the fermentation tank 1 from the feed pipe 21 for fermentation, the first gear 20 is driven to rotate intermittently by the stepping motor 19, the first gear 20 drives the auger pipe 2 to rotate through the second gear 17 engaged with the first gear 20, and the auger blade 3 installed on the outer side of the auger pipe 2 stirs the material in the fermentation tank 1, so as to avoid that the temperature at the center position of the material is too high and affects the fermentation effect.

[0021] In this embodiment, the cooling mechanism includes the first conduit 6 and the second conduit 7, the ends of the first conduit 6 and the second conduit 7 away from each other are respectively arranged through the two end portions of the auger pipe 2, and the other ends of the first conduit 6 and the second conduit 7 are respectively arranged in the two ends of the auger pipe 2, the inside of the auger pipe 2 is installed with a lifting mechanism for driving the temperature sensor 12 to move up and down, the lifting mechanism includes a piston block 8 movably installed in the inside of the auger pipe 2, the temperature sensor 12 is installed on the piston block 8, the first conduit 6 and the second conduit 7 are arranged through the outer surface of the piston block 8, the inside of the auger pipe 2 is installed with a lifting assembly for driving the piston block 8 to move, a swing assembly is installed between the piston block 8 and the temperature sensor 12, the lifting assembly includes a support frame 5 fixedly installed on the bottom of the fermentation tank 1, a reciprocating screw rod 4 is fixedly installed on the upper surface of the support frame 5, the reciprocating screw rod 4 is arranged through the inside of the auger pipe 2, and the reciprocating screw rod 4 is arranged on the same axis as the auger pipe 2, and the reciprocating screw rod 4 is arranged through the outer surface of the piston block 8 and is threadedly connected with the piston block 8.

[0022] The piston block 8 is driven to rotate synchronously with the auger pipe 2 through the first conduit 6 and the second conduit 7 while the auger pipe 2 rotates, the reciprocating screw rod 4 installed in the inside of the auger pipe 2 is fixedly installed with the fermentation tank 1 through the support frame 5, and the piston block 8 is threadedly connected with the reciprocating screw rod 4, so that the piston block 8 can move up and down along the axis of the reciprocating screw rod 4 while rotating, and the temperature sensor 12 installed on the piston block 8 can move up and down synchronously, so as to comprehensively monitor the temperature of the upper and lower layers in the inside of the fermentation tank 1, so as to ensure the comprehensiveness of the temperature monitoring of the material in the inside of the fermentation tank 1; when the piston block 8 moves up and down, the piston block 8 draws air and exhausts air into the inside of the auger pipe 2 through the first conduit 6 and the second conduit 7 respectively, so as to suck the cold air outside the fermentation tank 1 into the auger pipe 2 and exhaust the heat in the feed pipe 21 to the outside of the fermentation tank 1, so as to cool the temperature sensor 12 by the sucked cold air, avoid the heat in the inside of the fermentation tank 1 from being conducted to the temperature sensor 12, and gradually increase the temperature of the temperature sensor 12, which affects the subsequent detection effect of the temperature sensor 12.

[0023] In this embodiment, the swinging assembly includes an arc-shaped groove 9 opened on the outside of the piston block 8, and a sealing block 10 is rotatably installed on the inner wall of the arc-shaped groove 9. A rotatable sealing structure is formed between the sealing block 10 and the arc-shaped groove 9, so that the sealing block 10 can ensure rotation while having a certain sealing effect with the piston block 8, thereby separating the upper and lower sides of the piston block 10; a friction assembly is installed between the sealing block 10 and the inner wall of the auger tube 2, and a scaling assembly is installed between the sealing block 10 and the temperature sensor 12. The friction assembly includes two friction wheels 15 rotatably installed on the inner walls of the opposite sides of the arc-shaped groove 9. The friction wheels 15 are made of flexible sponge and have a certain deformation ability; a driving gear 16 is fixedly installed between the two friction wheels 15, and a transmission gear 14 is fixedly installed at the rotation center of the sealing block 10, and the transmission gear 14 is meshed with the driving gear 16.

[0024] As the piston block 8 moves up and down, the friction wheel 15 will rotate upward or downward under the friction with the inner wall of the auger tube 2, so that the friction wheel 15 drives the driving gear 16 to rotate, and the driving gear 16 drives the sealing block 10 to deflect in the opposite direction through the transmission gear 14 meshing therewith. After one side of the sealing block 10 is against the inner wall of the auger tube 2, the transmission gear 14 will not be able to rotate, so that the friction wheel 15 also stops rotating. Since the friction wheel 15 is made of flexible sponge, the friction wheel 15 will produce a certain deformation when the piston block 8 moves again, thereby ensuring the smoothness of the movement of the piston block 8; when the sealing block 10 flips, it will drive the temperature sensor 12 to swing synchronously, so that the temperature sensor 12 is in contact with the cold air entering the inside of the auger tube 2, so that the cold air can better cool the temperature sensor 12.

[0025] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, the mealworm nutrient material to be fermented is injected from the feed pipe 21 into the fermentation tank 1 for fermentation; The first gear 20 is intermittently driven by the stepping motor 19 to rotate, so that the first gear 20 drives the auger tube 2 to rotate through the second gear 17 meshing with it, so that the auger blades 3 installed on the outside of the auger tube 2 turn the material inside the fermentation tank 1 to prevent the temperature at the center of the material from being too high, which affects the fermentation effect; As the auger tube 2 rotates, the piston block 8 is driven to rotate synchronously through the first conduit 6 and the second conduit 7. Since the reciprocating screw 4 provided inside the auger tube 2 is fixedly installed with the fermentation tank 1 through the support frame 5, and the piston block 8 is threadedly connected to the reciprocating screw 4, the piston block 8 can also reciprocate up and down along the axis direction of the reciprocating screw 4 while rotating, so that the temperature sensor 12 installed on the piston block 8 can move up and down synchronously, so that the temperature sensor 12 can comprehensively monitor the upper and lower temperatures inside the fermentation tank 1, so as to ensure the comprehensiveness of the temperature monitoring of the material inside the fermentation tank 1; When the piston block 8 moves up and down, the piston block 8 will draw air into and exhaust air out of the auger pipe 2 through the first conduit 6 and the second conduit 7 respectively, so as to suck cold air outside the fermentation tank 1 into the auger pipe 2 and exhaust heat in the feed pipe 21 to the outside of the fermentation tank 1, so that the sucked cold air cools the temperature sensor 12, avoids the heat in the fermentation tank 1 from being conducted to the temperature sensor 12, and gradually increases the temperature of the temperature sensor 12, which affects the subsequent detection effect of the temperature sensor 12; When the temperature detection operation is performed, the auger pipe 2 stops rotating, and the temperature sensor 12 is stopped at any height for a certain period of time, so that the temperature sensor 12 detects the temperature of the material at this height, and ensures the accuracy of temperature detection; When the piston block 8 moves up and down, the friction wheel 15 will rotate upward or downward under the friction with the inner wall of the auger pipe 2, so that the friction wheel 15 drives the drive gear 16 to rotate, and the drive gear 16 drives the sealing block 10 to reverse deflect through the transmission gear 14 engaged with the drive gear 16. After the sealing block 10 is abutted against the inner wall of the auger pipe 2 on one side, the transmission gear 14 cannot rotate, so that the friction wheel 15 also stops rotating. Since the friction wheel 15 is made of flexible sponge, when the piston block 8 moves again, the friction wheel 15 will deform to ensure the smoothness of the movement of the piston block 8. The sealing block 10 will drive the temperature sensor 12 to swing synchronously when it is turned over, so that the temperature sensor 12 is in contact with the cold air entering the inside of the auger pipe 2, so that the cold air can better cool the temperature sensor 12.

[0026] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
