[0030] Each lifting mechanism comprises a fixed seat 13 fixed to the inner wall of the U-shaped frame 2, and two electric push rods 14 are symmetrically fixed to the upper end face of the fixed seat 13, and the distal end of the telescopic end of the electric push rod 14 is fixedly connected with the upper end face of the lifting plate 7.

[0031] In the initial state, the telescopic end of the electric push rod 14 is in the retracted state, when it is needed to move the lifting plate 7 downward with the mounting disc 8 and the breathable needle 9, at this time, the telescopic end of the electric push rod 14 is elongated, thereby pushing the lifting plate 7 to move downward with the mounting disc 8 and the breathable needle 9.

[0032] Each lighting unit comprises two translation plates 15, and a sliding through groove 16 is formed in the inner wall of the U-shaped frame 2 for cooperation with the translation plate 15, a plurality of light bars 17 are fixed to the lower end face of each translation plate 15, two rack plates 18 are symmetrically fixed to the upper end face of the translation plate 15, a gear 19 is rotatably arranged on the inner wall of each sliding through groove 16, the gear 19 is in meshing connection with the rack plate 18, a drive box 20 is arranged on the outer side wall of the U-shaped frame 2 for cooperation with the rotation of the gear 19, and a limiting piece is arranged between each sliding through groove 16 and the translation plate 15.

[0033] In the initial state, the translation plate 15 is located above the placing plate 3, and through the arranged light bar 17, the mycelium of the culture tank 5 located on the placing plate 3 can be illuminated, when it is needed to pierce the sealing film 6 on the culture tank 5 to be breathable, at this time, the drive box 20 drives the corresponding gear 19 to rotate, under the cooperation of the rack plate 18, the two translation plates 15 used in cooperation begin to move away from each other, thereby avoiding affecting the downward movement of the lifting plate 7.

[0034] Each limiting piece comprises a T-shaped sliding groove formed in the bottom of the sliding through groove 16, a T-shaped sliding block 21 is slidably arranged in the T-shaped sliding groove, and the T-shaped sliding block 21 is fixed to the lower end face of the translation plate 15.

[0035] Through the cooperation of the T-shaped sliding groove and the T-shaped sliding block 21, the translation of the translation plate 15 is limited, thereby avoiding the phenomenon that the translation plate 15 falls over when moving in the direction away from the U-shaped frame 2.

[0036] A plurality of lifting horizontal rods 22 are movably arranged on both sides of the U-shaped frame 2, and the upper end surface of each lifting horizontal rod 22 is obliquely fixed with a brush layer 23. A plurality of lifting mechanisms two are arranged on the U-shaped frame 2 and used in cooperation with the corresponding lifting horizontal rods 22. Two cleaning units are arranged on each fixed seat 13 and used in cooperation with the corresponding brush layer 23.

[0037] In the initial state, the lifting horizontal rod 22 and the brush layer 23 are located on one side of the corresponding fixed seat 13, so as to avoid affecting the placement and taking of the placement plate 3.

[0038] In use, the lifting horizontal rod 22 is moved downward by the lifting mechanism two until the lifting horizontal rod 22 and the brush layer 23 move below the corresponding translation plate 15. When the translation plate 15 translates, the light bar 17 moves with the translation plate 15. At this time, the brush layer 23 can wipe the dust on the surface of the light bar 17, so as to avoid affecting the lighting effect of the light bar 17. When the brush layer 23 finishes wiping and cleaning the light bar 17 on the translation plate 15, the translation plate 15 resets. At this time, the lifting horizontal rod 22 and the brush layer 23 also move upward to the initial position.

[0039] Each lifting mechanism two includes two driving members. Each driving member includes an upper mounting plate 24 and a lower mounting plate 25. The upper mounting plate 24 and the lower mounting plate 25 are fixed to the outer side wall of the U-shaped frame 2. A lifting block 26 is movably arranged between the upper mounting plate 24 and the lower mounting plate 25. The lifting block 26 is fixed to one side of the lifting horizontal rod 22. A lead screw 27 is rotatably arranged between the upper mounting plate 24 and the lower mounting plate 25. The lead screw 27 is threaded through the lifting block 26. The upper end surface of the upper mounting plate 24 is provided with a working motor 28 used in cooperation with the rotation of the lead screw 27.

[0040] When the working motor 28 rotates, the lead screw 27 is driven to rotate. The rotating lead screw 27 drives the lifting block 26 to move, thereby driving the lifting horizontal rod 22 and the brush layer 23 to move.

[0041] Each cleaning unit includes a translation block 29 movably arranged on one side of the fixed seat 13. A blowing nozzle 30 is fixedly arranged on the translation block 29. A gas supply pump 31 is fixedly arranged on the fixed seat 13 and used in cooperation with the corresponding blowing nozzle 30. A telescopic air hose 32 is in communication between the gas outlet of the gas supply pump 31 and the blowing nozzle 30.

[0042] When the brush layer 23 needs to be cleaned after being used for a period of time, the gas supply pump 31 works to supply air to the blowing nozzle 30 through the telescopic air hose 32, so as to blow and clean the brush layer 23 through the blowing nozzle 30.

[0043] Each fixed base 13 has an electric slide rail 33 fixed on both sides, and an electric slider 34 is movably mounted on each electric slide rail 33. The translation block 29 is fixed to the upper end face of the electric slider 34.

[0044] During operation, the electric slide rail 33 can drive the electric slider 34 to move horizontally, thereby moving the translation block 29 and the air nozzle 30 to move horizontally, and cooperate to clean the brush layer 23.

[0045] In use, the present invention cultivates liquid bacteria in a culture tank 5. When the surface of the culture medium in the culture tank 5 has protrusions and forms millet-like primordia, it is necessary to reduce the humidity in the culture tank 5. At this time, the lighting unit moves horizontally, and then the lifting mechanism drives the lifting plate 7 to move downward, thereby moving the mounting plate 8 and the corresponding ventilating needle 9 toward the sealing film 6 until the ventilating needle 9 punctures the corresponding sealing film 6. It is not necessary to manually process each culture tank 5, which saves effort. Then the lifting mechanism drives the lifting plate 7 to move upward to the initial position, at which time the lighting unit is reset. In use, the culture tank 5 containing liquid inoculum and covered with a sealing film 6 is placed in the placement groove 4. The placement groove 4 positions and limits the culture tank 5, preventing displacement of the culture tank 5 on the placement plate 3 when it is placed or removed. The placement plate 3, which supports the culture tank 5, is pushed into the corresponding pull-out groove 10. The placement plate 3 moves within the pull-out groove 10. At this time, the side wall of the placement plate 3 presses against the abutment ball 12, and the abutment ball 12 compresses the spring. The spring stores elastic potential energy. When the abutment groove 35 on the placement plate 3 is aligned with the abutment ball 12, the placement plate 3 no longer applies force to the abutment ball 12. At this time, the abutment ball 12, under the action of the spring, abuts against the abutment groove 35, thereby limiting and positioning the placement plate 3, thus cooperating to position the culture tank 5 and causing the culture tank 5 to be located below the corresponding mounting plate 8. In the initial state, the translation plate 15 is located above the placement plate 3. The light strip 17 can provide light to the mycelium of the culture tank 5 located on the placement plate 3. When it is necessary to puncture the sealing film 6 on the culture tank 5 to allow air to pass through, the drive box 20 drives the corresponding gear 19 to rotate. With the cooperation of the rack plate 18, the two translation plates 15 used together start to move away from each other to avoid affecting the downward movement of the lifting plate 7. The translation of the translation plate 15 is limited by the cooperation of the T-shaped slide and the T-shaped slider 21 to prevent the translation plate 15 from flipping and falling off when it moves away from the U-shaped frame 2. In the initial state, the lifting crossbar 22 and the brush layer 23 are located on one side of the corresponding fixed base 13 to avoid affecting the placement and retrieval of the placement plate 3. During use, the lifting crossbar 22 can be moved downward by the lifting mechanism 2 until the lifting crossbar 22 and the brush layer 23 move to the bottom of the corresponding sliding plate 15. When the sliding plate 15 is slid, the light strip 17 moves with the sliding plate 15. At this time, the brush layer 23 can wipe the dust on the surface of the light strip 17 to avoid affecting the lighting effect of the light strip 17. When the brush layer 23 needs to be cleaned after a period of use, the air pump 31 works and supplies air to the air nozzle 30 through the telescopic air hose 32. The air nozzle 30 is used to clean the brush layer 23. During the operation of the air nozzle 30, the electric slide rail 33 can drive the electric slider 34 to move horizontally, thereby moving the translation block 29 and the air nozzle 30 to move horizontally, and working together to clean the brush layer 23.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
