[0021] A method for using a tray stacking machine for plant stem cell culture trays, comprising the following steps:

[0022] Step 1: multiple groups of culture dishes containing plant stem cells are placed on the second conveyor belt, and the multiple groups of culture dishes are moved by the second conveyor belt so that the culture dishes can enter the moving box through the inclined panel in sequence, and the culture dishes fall on the third conveyor belt;

[0023] Step 2: Start the third conveyor belt, and drive the multiple groups of culture dishes to move in sequence in the moving box through the third conveyor belt until the multiple groups of culture dishes move to the slotted position, stop the third conveyor belt, start the multiple groups of propulsion cylinders, and the air intake pump sucks the external gas into the propulsion cylinders, thereby pushing the push plate to move, so that the push plate pushes the multiple groups of culture dishes;

[0024] Step 3: The culture dish passes through the slot and enters a group of collection boxes. When the culture dish moves in the collection box, it pushes the moving plate to move. The moving plate moves to squeeze the air in the collection box, so that the air in the collection box enters the conduit through the air inlet, and finally ejects through the air jet slot along the conduit, and performs air jet treatment on the outside of the culture dish;

[0025] Step 4: Reversely start the air intake pump to extract the gas in the propulsion cylinder and return the push plate to its original position.

[0026] Step 5: When one set of collection boxes is filled, the push plate cannot push the multiple sets of culture dishes into the collection boxes, but the air intake pump will continue to operate according to the set program, and the outside air will continue to enter the propulsion cylinder. The air pressure in the propulsion cylinder will continue to increase until it exceeds the elastic limit of the limit spring in the interception valve, so that the interception plate slides along the limit rod, and the multiple sets of interception valves open, and the air flow will enter the first air pipe and the second air pipe;

[0027] Step 6: The length of the first air pipe is much smaller than that of the second air pipe. The airflow will first enter the shielding cylinder and push the blocking rod to move to the outside of the push plate to intercept the push plate.

[0028] Step 7: The remaining gas enters the control mechanism through the second gas pipe and pushes the power board to move. The power board connects the drive motor to the external power supply. The drive motor drives the outer lifting belt to move through the rotating shaft. The lifting belt drives the collection box to move upward through the outer lifting plate.

[0029] Step 8: After the air intake pump runs for a period of time according to the program, it will reset. At this time, the air intake pump will extract the air in the propulsion cylinder. During the reset process, the return spring will push the stopper back to its position, and the buffer spring will push the power board back to its position. In the process of returning to its position, the gas in the first air pipe and the second air pipe will be pushed back to the propulsion cylinder through the interception valve, and the propulsion cylinder will return to its position;

[0030] Step 9: While the propulsion cylinder is returning, start the first conveyor belt, move the empty collection box to the outside of the slot again, and engage the connecting plates on both sides of the collection box with a set of lifting plates to facilitate subsequent collection.

[0031] In summary, the present invention mainly has the following beneficial effects:

[0032] The present invention provides multiple groups of conveyor belts, lifting belts, collecting boxes and propulsion cylinders. When replacing culture dishes, the multiple groups of culture dishes are first placed on the second conveyor belt, and the multiple groups of culture dishes are transported by the second conveyor belt, so that the culture dishes are moved on the second conveyor belt and enter the moving box.

After the collecting box is fully installed, the propulsion cylinder is self-locked by the shielding cylinder, and the continuous operation of the propulsion cylinder can start the driving motor, and the lifting belt is moved by the driving motor, so that the lifting belt can drive the collecting box to move, and the empty collecting box is moved by the first conveyor belt, so that more culture dishes can be conveniently collected, and the problem of poor efficiency in replacing culture dishes is effectively solved.

[0033] The present invention, through the provided collecting box and the moving plate, can push the moving plate through the culture dish when collecting the culture dish, the moving plate squeezes the air in the collecting box, the air enters the duct through the air inlet, and is ejected from the air jet slot along the duct, thereby jetting the air to the outside of the culture dish, so that when collecting the culture dish, the air flow can clean the culture dish, thereby reducing the external dust from entering the collecting box, improving the cleanliness of the culture dish, and effectively solving the problem of inconvenience in isolating from the outside.

[0054] When the device is used, firstly, multiple groups of culture dishes containing plant stem cells are placed on the second conveyor belt 4, and the multiple groups of culture dishes are moved by the second conveyor belt 4, so that the culture dishes can enter the moving box 1 through the inclined panel 101 in sequence, and then the third conveyor belt 5 is started, and the multiple groups of culture dishes are driven to move in sequence in the moving box 1 by the third conveyor belt 5 until the multiple groups of culture dishes move to the slot 102 position, at this time, the third conveyor belt 5 is stopped, and the multiple groups of propulsion cylinders 8 are started, and the air intake pump 804 sucks the external gas into the propulsion cylinder 8, thereby pushing the push plate 805 to move, so that the push plate 805 pushes the multiple groups of culture dishes, so that the culture dishes pass through the slot 102 and enter a group of collecting boxes 7, and when the culture dishes move in the collecting box 7, The movable plate 12 is pushed to move, and the movable plate 12 moves to squeeze the air in the collecting box 7, so that the air in the collecting box 7 enters the conduit 705 through the air inlet 706, and is finally ejected through the air jet slot 703 along the conduit 705, and the air entering the outside of the culture dish is subjected to air jet treatment, thereby reducing the external dust from entering the collecting box 7.

5. The method for using the tray stacking machine for plant stem cell culture trays according to claim 1, characterized in that: The following steps are involved: Step 1: placing multiple groups of culture dishes containing plant stem cells on the second conveyor belt, and moving the multiple groups of culture dishes through the second conveyor belt so that the culture dishes can enter the moving box through the inclined panel in sequence, and the culture dishes fall on the third conveyor belt; Step 2: Start the third conveyor belt, and drive the multiple groups of culture dishes to move in sequence in the moving box through the third conveyor belt until the multiple groups of culture dishes move to the slotted position, stop the third conveyor belt, start the multiple groups of propulsion cylinders, and the air intake pump sucks the external gas into the propulsion cylinders, thereby pushing the push plate to move, so that the push plate pushes the multiple groups of culture dishes; Step 3: The culture dish passes through the slot and enters a group of collection boxes. When the culture dish moves in the collection box, it pushes the moving plate to move. The moving plate moves to squeeze the air in the collection box, so that the air in the collection box enters the conduit through the air inlet, and finally ejects through the air jet slot along the conduit, and performs air jet treatment on the outside of the culture dish; Step 4: Reversely start the air intake pump to extract the gas in the propulsion cylinder and return the push plate to its original position. At this time, start the third conveyor belt again to drive the multiple groups of culture dishes to move to the side of the push plate again, and fill the multiple groups of culture dishes again; Step 5: When one set of collection boxes is filled, the push plate cannot push the multiple sets of culture dishes into the collection boxes, but the air intake pump will continue to operate according to the set program, and the outside air will continue to enter the propulsion cylinder. The air pressure in the propulsion cylinder will continue to increase until it exceeds the elastic limit of the limit spring in the interception valve, so that the interception plate slides along the limit rod, and the multiple sets of interception valves open, and the air flow will enter the first air pipe and the second air pipe; Step 6: The length of the first air pipe is much smaller than that of the second air pipe. The airflow will first enter the shielding cylinder and push the blocking rod to move to the outside of the push plate to intercept the push plate. Step 7: The remaining gas enters the control mechanism through the second gas pipe and pushes the power board to move. The power board connects the drive motor to the external power supply. The drive motor drives the outer lifting belt to move through the rotating shaft. The lifting belt drives the collection box to move upward through the outer lifting plate. Step 8: After the air intake pump runs for a period of time according to the program, it will reset. At this time, the air intake pump will extract the air in the propulsion cylinder. During the reset process, the return spring will push the stopper back to its position, and the buffer spring will push the power board back to its position. In the process of returning to its position, the gas in the first air pipe and the second air pipe will be pushed back to the propulsion cylinder through the interception valve, and the propulsion cylinder will return to its position; Step 9: While the propulsion cylinder is returning, start the first conveyor belt, move the empty collection box to the outside of the slot again, and engage the connecting plates on both sides of the collection box with a set of lifting plates to facilitate subsequent collection.
