[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 , a scribing trigger for inoculating and separating microorganisms in the first area of the culture medium, including a frame table 1;

[0031] Both sides of the frame table 1 are equipped with turntables 2. Each turntable 2 rotates a petri dish storage rack 3. One group of petri dish storage racks 3 is used to place unprocessed petri dishes, and the other group is used to place processed petri dishes. A rotating motor 9 is fixed to the bottom side of the turntable 2, and the output shaft of the rotating motor 9 is fixedly connected to the center of the bottom side of the petri dish storage rack 3 for driving the petri dish storage rack 3 to rotate;

[0032] A petri dish inoculation scribing and separation device 4 is also provided on the frame table 1 between the two turntables 2;

[0033] A culture dish handling device 5 is also provided on the rack table 1. The culture dish handling device 5 is used to transfer the untreated culture dishes taken out from a group of culture dish storage racks 3 to the culture dish inoculation and streaking separation device 4 for inoculation and then transfer them to another group of culture dish storage racks 3.

[0034] Please refer to Figures 1-9 , a streaking machine for inoculating and separating microorganisms in the first area of the culture medium. A plurality of vertical bins 31 are provided on the periphery of the culture dish storage rack 3. The vertical bins 31 are used to stack a plurality of groups of culture dishes. The side of the vertical bin 31 is open. The bottom wall of the vertical bin 31 for placing untreated culture dishes is provided with a pushing channel opening 32. A culture dish slideway 21 is provided on the rear side of the turntable 2 close to the culture dish handling device 5. When the culture dish storage rack 3 rotates, a plurality of pushing channel openings 32 are driven to rotate in sequence to be directly opposite to the culture dish slideway 21 and located in the same plane. The bottom wall of the vertical bin 31 for placing the treated culture dishes is also provided with a pushing channel opening 32. As the culture dish storage rack 3 rotates, the pushing channel openings 32 at the bottoms of the plurality of vertical bins 31 move to the front end above the culture dish slideway 21 in sequence. The size of the pushing channel opening 32 of the vertical bin 31 for placing the treated culture dishes is larger than the size of the culture dish. Both the left and right sides and the front side of the top surface of the pushing channel opening 32 are hinged with a support plate 33. The stacked treated culture dishes are supported by the plurality of support plates 33. When the treated culture dishes move to the front end along the culture dish slideway 21, they are located directly below the pushing channel opening 32.

[0035] A horizontal pushing component 6 is provided at the bottom side of the turntable 2. The horizontal pushing component 6 is used to push the treated culture dishes from the rear end to the front end of the culture dish slideway 21 until they are pushed directly below the pushing channel opening 32, or to push the untreated culture dishes from a group of vertical bins 31 onto the opposite culture dish slideway 21 for pushing out the untreated culture dishes. A positioning groove 22 is provided at the rear end of the culture dish slideway 21 on the turntable 2 for placing the untreated culture dishes, so that the removed untreated culture dishes slide into the positioning groove 22 for positioning and clamping, which is convenient for the electric claw 53 in the culture dish handling device 5 to perform positioning and clamping.

[0036] On the rack table 1, a pushing-up component 7 is arranged at the bottom side of the culture dish bin. When the top end of the pushing-up component 7 located below the unprocessed culture dish penetrates through the bottom wall of a set of vertical bins 31 close to the culture dish slideway 21 and protrudes, it jacks up the stacked culture dishes in the vertical bins 31. When the pushing-up component 7 located below the processed culture dish extends, its top end pushes up the processed culture dish that has moved to directly below the pushing channel opening 32, and the processed culture dish passes through the pushing channel opening 32 and is pushed into the vertical bin 31. During the pushing-up process, the processed culture dish first jacks up the supporting plate 33 to swing upward, expanding the spacing for the processed culture dish to pass through. After the processed culture dish moves above the supporting plate 33, the supporting plate 33 falls back, and then the pushing-up component 7 retracts, so that the processed culture dish can fall back onto the supporting plate 33 again for lifting and bearing.

[0037] On the turntable 2 for placing unprocessed culture dishes, a limiting component 8 is fixed above the culture dish slideway 21. The limiting component 8 extends into the side opening of a set of vertical bins 31 close to the culture dish slideway 21 to laterally press and limit the culture dishes jacked up by the pushing-up component 7. The limiting component 8 corresponding to the culture dish bin rack 3 for placing unprocessed culture dishes is used to laterally press and limit the second group of culture dishes jacked up by the pushing-up component 7 from the bottom side. At this time, the transverse pushing component 6 moves into the pushing channel opening 32. After the pushing-up component 7 retracts, the lowermost unprocessed culture dish falls back to the bottom of the vertical bin 31. At this time, the transverse pushing component 6 pushes this group of unprocessed culture dishes out of the vertical bin 31 along the directly opposite and connected pushing channel opening 32 and culture dish slideway 21 to the end of the culture dish slideway 21, waiting for the culture dish handling device 5 to clamp and transfer them.

[0038] Please refer to Figure 7 , a scribing trigger for inoculating and separating microorganisms in the first area of the culture medium. The pushing-up component 7 includes a screw motor 71 fixed on the rack table 1 and located below the culture dish bin rack 3. A screw fixed to the output shaft of the screw motor 71 is sleeved in an installation plate 72 through a threaded hole. At the same time, the installation plate 72 is also slidably connected to a slide bar fixed on the rack table 1. The top ends of the vertical rods 73 on both sides of the installation plate 72 are both fixed with top plates 74. When the two groups of top plates 74 located below the culture dish bin rack 3 for placing unprocessed culture dishes move upward, they slide through the bottom wall of the culture dish bin rack 3 and are located on both sides of the pushing channel opening 32 to jack up the culture dishes in the vertical bin 31. When the two groups of top plates 74 located below the culture dish bin rack 3 for placing processed culture dishes move upward, they jack up the processed culture dish at the front end of the culture dish slideway 2 and directly below the pushing channel opening 32, and push it up to pass through the pushing channel opening 32 and be pushed into the vertical bin 31.

[0039] An origin sensor 75 is provided on the frame table 1. At the same time, an induction piece 76 is provided on the mounting plate 72. When the mounting plate 72 moves down and resets, the induction piece 76 moves to the position of the origin sensor 75. The origin sensor 75 detects whether the induction piece 76 is reset, so as to detect whether the top plate 74 is reset. The origin sensor 75 is signal-connected to the screw motor 71, and the start and stop states of the screw motor 71 are controlled by the feedback signal.

[0040] Please refer to Figures 5-6 , a scriper for inoculating and separating microorganisms in the first culture medium area. The horizontal pushing component 6 includes a horizontal pushing electric screw rod 61 fixed on the frame table 1 and located at the bottom side of the turntable 2. A horizontal pushing plate 63 is fixed on the slider 62 in the horizontal pushing electric screw rod 61. The horizontal pushing plate 63 slides in the connecting pushing channel opening 32 and the culture dish slideway 21 at the place where the untreated culture dish is placed, so as to push the untreated culture dish from a group of vertical bins 31 onto the corresponding culture dish slideway 21 for pushing out the untreated culture dish, or push the treated culture dish from the rear end to the front end of the culture dish slideway 21 to the lower side of a group of vertical bins 31 for placing the treated culture dish; An origin sensor 64 is fixed on the turntable 2. At the same time, an induction piece 65 is fixed on the slider 62. When the slider 62 resets, the induction piece 65 moves to the position of the origin sensor 64. The origin sensor 64 detects whether the induction piece 65 is reset, so as to detect whether the horizontal pushing plate 63 is reset.

[0041] Please refer to Figure 2 , a scriper for inoculating and separating microorganisms in the first culture medium area. The limiting component 8 includes a motor fixing plate 81 fixed on the turntable 2 and located above the culture dish slideway 21. A side pressing motor 82 is fixed on the motor fixing plate 81. A gear 83 fixed on the output shaft of the side pressing motor 82 meshes with a linkage rack 85 fixed on a rack fixing plate 84 sliding on the motor fixing plate 81. By rotating the side pressing motor 82, the rack fixing plate 84 is driven to slide back and forth by the meshing of the gear teeth, so as to move closer to or away from the culture dish rack 3, and realize the lateral pressing of the culture dish in the culture dish rack 3; Two culture dish rollers 86 are rotatably installed on both sides of the front end of the rack fixing plate 84 close to the culture dish rack 3. When the rack fixing plate 84 moves forward, the two culture dish rollers 86 are used to penetrate into the vertical bin 31 and contact and press against the side wall of the culture dish therein.

[0042] On the motor fixing plate 81, there is a second origin sensor 87. At the same time, on the rack fixing plate 84, there is a second induction piece 88. When the rack fixing plate 84 moves backward and resets, the second induction piece 88 moves to the position of the second origin sensor 87. The second origin sensor 87 detects whether the second induction piece 88 is reset, thereby detecting whether the rack fixing plate 84 is reset. The second origin sensor 87 is signal-connected to the side pressure motor 82, and controls the start and stop state of the side pressure motor 82 through the feedback signal.
