The sealing door 3 cooperates with the thermostatic box 2. The front and rear sides of the top of the thermostatic box 2 are fixedly connected with fixing plates 6 symmetrically. The guide tube 4 is fixedly connected between the four fixing plates 6 and the upper left side of the thermostatic box 2. Two osmotic drip valves 5 are fixedly connected to the right side of the bottom of the front and rear sides of the guide tube 4 and are connected. A placement mechanism 7 is provided in the lower part of the thermostatic box 2. The placement mechanism 7 is located below the osmotic drip valve 5. A liquid supply mechanism 8 is provided in the middle of the top left side of the base 1. The liquid supply mechanism 8 is fixedly connected and connected to the middle of the top left side of the osmotic drip valve 5.

[0027] The placement mechanism 7 includes a guide rail 71, a support frame 72, rollers 73 and positioning pins 74. The guide rails 71 are fixedly connected to the lower parts of the front and rear side surfaces in the constant temperature box 2. Four grooves are evenly spaced apart on the upper parts of the inner sides of the guide rails 71 on both sides. Rollers 73 are evenly spaced apart and slidingly placed inside the guide rails 71. The support frame 72 is rotatably connected between all the rollers 73 on both sides of the front and rear. Four positioning pins 74 are evenly spaced apart on the upper parts of the front and rear side surfaces of the support frame 72. The positioning pins 74 are located in the grooves of the guide rails 71 and cooperate with them.

[0028] The liquid supply mechanism 8 includes a liquid storage tank 81, a buffer tube 82, a positioning block 83 and a control ball valve 84. The liquid storage tank 81 is fixedly connected to the middle of the left top of the base 1, two positioning blocks 83 are fixedly connected to the left outer top of the constant temperature box 2, and a buffer tube 82 is fixedly connected between the left inner sides of the two positioning blocks 83.

[0029] First, the operator opens the sealing door 3, pulls the placement mechanism 7 to move rightward to the outside of the thermostat 2, then places four culture dishes with biological samples in the placement mechanism 7, pushes the placement mechanism 7 to move leftward to reset and drive the culture dishes to move leftward to the thermostat 2, and then pulls the sealing door 3 to close, and then an appropriate amount of nutrient water can be poured into the liquid supply mechanism 8. When nutrient water needs to be dripped into the culture dish, the liquid supply mechanism 8 is twisted so that the nutrient water is discharged into the guide tube 4, and the nutrient water in the guide tube 4 is discharged into the osmotic drip valve 5, and the nutrient water in the osmotic drip valve 5 drips into the culture dish. When an appropriate amount of nutrient water drips into the culture dish, the liquid supply mechanism 8 is twisted to close, and the nutrient water stops being discharged into the guide tube 4, and the osmotic drip valve 5 also stops dripping the nutrient water.

When the culture dish needs to drip nutrient water, the control ball valve 84 is twisted to not block the nutrient water, and the nutrient water is discharged into the guide tube 4, and the osmotic drip valve 5 also allows the nutrient water to drip into the culture dish. When a proper amount of nutrient water drips into the culture dish, the control ball valve 84 is twisted to close, and the nutrient water stops being discharged into the guide tube 4.

[0031] When the sealed door 3 is opened, the carrier 72 is pulled to move rightward through the roller 73, and the carrier 72 moves rightward to drive the positioning pin 74 to move rightward. When the carrier 72 moves rightward outside the thermostat 2, the carrier 72 is stopped from being pulled, and the positioning pin 74 fixes the carrier 72, and the culture dish containing the biological sample can be placed in the carrier 72. After the culture dish is placed, the carrier 72 is pushed to move leftward to reset, and the carrier 72 resets and drives the culture dish to move leftward into the thermostat 2, and the positioning pin 74 limits the carrier 72, and the sealed door 3 is closed. Similarly, when the culture dish needs to be taken out, the sealed door 3 is opened according to the above operation, the carrier 72 is pulled to move rightward to the outside of the thermostat 2, the culture dish is taken out, the carrier 72 is pushed to move leftward to reset, and the sealed door 3 is closed.

[0035] When nutrient water needs to be dripped into the culture dish, the control ball valve 84 is twisted to open and the servo motor 91 is started. The servo motor 91 rotates to drive the drive shaft 92 to rotate, and the drive shaft 92 rotates to drive the first transmission component 94 to rotate. The first transmission component 94 rotates to drive the fixed shaft 93 to rotate, and the fixed shaft 93 rotates to drive the eccentric groove wheel 95 to rotate. The rotation of the eccentric groove wheel 95 drives the sealing push block 96 to move forward and backward. When the sealing push block 96 moves forward, the sealing push block 96 moves forward through the upper one-way valve 97 to draw the nutrient water in the liquid storage tank 81 into the buffer tube 82. When the sealing push block 96 moves backward, the sealing push block 96 pushes the nutrient solution in the buffer cylinder into the control ball valve 84 through the lower one-way valve 97, and the nutrient solution also falls into the culture dish through the osmotic drip valve 5. This is repeated, and an equal amount of nutrient water can be dripped out each time. When an appropriate amount of nutrient water is dripped in the culture dish, the servomotor 91 is turned off, the drive shaft 92 stops rotating, and the sealing push block 96 also stops moving back and forth, and the nutrient water stops being discharged into the buffer tube 82. In this way, an equal amount of nutrient water can be dripped out each time.

[0036] When the servo motor 91 is started, the fixed shaft 93 rotates and also drives the second transmission assembly 102 to rotate. The rotation of the second transmission assembly 102 drives the positioning shaft 101 to rotate. The rotation of the positioning shaft 101 drives the stirring plate 103 to rotate. At the same time, the rotation of the positioning shaft 101 also drives the middle gear 107 to rotate. The rotation of the middle gear 107 drives the gears 107 on both sides to rotate inward. The inward rotation of the gears 107 on both sides drives the screw 108 to rotate. The rotation of the front screw 108 drives the guide wheel 1011 to move leftward. The guide wheel 1011 moves leftward and drives the swing straight rod 1010 to move leftward. The straight rod 1010 moves to the left, driving the guide magnetic block 1012 to move to the left. The guide magnetic block 1012 moves to the left, driving the guide iron frame 1015 to move to the left. When the guide magnetic block 1012 moves to the left and corresponds to the front strong magnetic block 1014, the front strong magnetic block 1014 drives the guide magnetic block 1012 to move backward because the strong magnetic block 1014 repels the guide magnetic block 1012. The guide magnetic block 1012 moves backward, driving the lower part of the swing straight rod 1010 to swing backward. The swinging of the lower part of the swing straight rod 1010 causes the upper part to swing forward. The swinging of the upper part of the swing straight rod 1010 forward drives the positioning rod 109 The hopper 105 is reversed and connected to the front of the discharge box 104. At the same time, the lower part of the swing straight rod 1010 swings backward, driving the guide wheel 1011 to swing backward and engage with the rear screw 108. The rear screw 108 rotates and drives the guide wheel 1011 to move right, which also makes the swing straight rod 1010 move right. When the guide magnetic block 1012 moves right and corresponds to the rear strong magnetic block 1014, the strong magnetic block 1014 drives the guide magnetic block 1012 to move forward and reset, which also makes the hopper 105 rotate forward and reset to the discharge box 104. 04 is connected to the rear part, the operator can pour the two liquids used to make nutrient water into the front and rear parts of the lower feed box 104 respectively. When the hopper 105 is reversed and connected to the front part of the lower feed box 104, the liquid in the front part of the lower feed box 104 is discharged into the hopper 105, and the liquid in the hopper 105 is discharged into the liquid storage tank 81. When the hopper 105 rotates forward and is connected to the rear part of the lower feed box 104, the liquid in the rear part of the lower feed box 104 is discharged into the hopper 105, and the liquid in the hopper 105 is discharged into the liquid storage tank 81. The stirring plate 103 stirs the two liquids, and the two liquids are stirred into nutrient water. When the servo motor 91 is turned off, the fixed shaft 93 stops driving the second transmission assembly 102 to rotate, the stirring plate 103 stops rotating, and the swing straight rod 1010 stops moving left and right. In this way, there is no need for the operator to stir the two liquids into nutrient water before pouring them into the liquid storage tank 81, which saves time and effort.

[0037] When the carrier 72 moves to the right outside the incubator 2, the operator can put the culture dish into the positioning block 111, the culture dish contacts the rubber force plate 117, push the culture dish downward to drive the rubber force plate 117 downward, the rubber force plate 117 moves downward to drive the positioning straight rod 118 downward, and the rubber force plate 117 moves downward to drive the connecting plate 114 downward, the support spring 116 is compressed, the connecting plate 114 moves downward to drive the clamping block 112 downward, and the clamping block 112 moves downward through the positioning wheel 113 so that the upper part moves inward.
