A circular moving layout structure of stacked biological culture trays on a ground, comprising display areas, a waiting transfer area and an operation area, wherein each of the display areas comprises a plurality of tray array areas, each of the tray array areas comprises a plurality of tray body areas, and the plurality of tray body areas are arranged in a single row along a first direction, and one of stacked biological culture tray bodies is correspondingly placed in each of the tray body areas in each of the tray array areas, and the stacked biological culture tray bodies are used for cultivating preset organisms, vertical projection areas of each of stacked biological culture tray bodies in each of the tray array areas on a ground are connected in a rectangular outline, each of the tray array areas is rectangular with long sides in the first direction, and a plurality of the tray array areas are arranged as the display areas along a second direction, and the first direction and the second direction are vertically arranged;
- the waiting transfer area comprises a temporary tray array area and at least one tray reversing area, wherein the temporary tray array area is used for temporarily accommodating all the stacked biological culture tray bodies in at least one of the tray array areas, and the tray reversing area is used for temporarily accommodating at least one of the stacked biological culture tray bodies;
- the tray reversing area is arranged at an end of the temporary tray array area and communicates with the temporary tray array area from one side, or, the tray reversing area is arranged in a middle of the temporary tray reversing area to divide the temporary tray array area into two sections and communicate with the temporary tray array area from two sides;
- the temporary tray array area is used in cooperation with the tray reversing area, so as to perform preset operation on each of the stacked biological culture tray bodies;
- vertical projection areas of all the stacked biological culture tray bodies accommodated in the waiting transfer area on the ground are connected in a rectangular outline, the waiting transfer area is rectangular with long sides in the second direction, and a length of the waiting transfer area is greater than a sum of a length of at least one of the tray array areas and a length of the tray reversing area;
- a long side of the waiting transfer area corresponds to a short side of each of the tray array areas in each of the display areas, a width of the waiting transfer area is greater than or equal to a maximum side length of each of the tray body areas, the waiting transfer area is interconnected with each of the tray array areas in each of the display areas, and all the stacked biological culture tray bodies in each of the tray array areas perform barrier-free sequential circular movement between the tray array areas and the waiting transfer area in a full-in and full-out manner;
- the waiting transfer area is connected with the operation area for use;
- the operation area is used for arranging a reciprocating operation device of being capable of moving back and forth, and the reciprocating operation device moves back and forth on two long sides of the waiting transfer area in the second direction;
- vertical projection areas of the reciprocating operation device on the ground are connected in a rectangular outline during reciprocating movement;
- the operation area covers the waiting transfer area;
- a width of the operation area is greater than a width of the waiting transfer area;
- a length of the operation area is greater than or equal to a length of the waiting transfer area, so that the reciprocating operation device is capable of riding across the waiting transfer area for reciprocating movement, and during reciprocating movement, preset operation is performed on the stacked biological culture tray bodies in any position of the temporary tray array area by the tray reversing area, and a barrier-free movement of the stacked biological culture tray bodies between each of the tray array areas and the waiting transfer area is not hindered;
- or, the operation area is used for arranging reciprocating operation device of being capable of moving reciprocally, and the reciprocating operation device moves reciprocally along a long side of the waiting transfer area in the second direction, and vertical projection areas of the reciprocating operation device on the ground during reciprocating movement are connected in a rectangular outline, and the operation area is adjacent to the waiting transfer area, and a length of the operation area is greater than or equal to a length of the waiting transfer area, so that the reciprocating operation device is capable of moving reciprocally along a side of the waiting transfer area, and during reciprocating movement, preset operation is performed on the stacked biological culture tray bodies in any position of the temporary tray array area by the tray reversing area, and a barrier-free movement of the stacked biological culture tray bodies between the tray array areas and the waiting transfer area is not hindered;
- one of the display areas is configured in one waiting transfer area and one operation area, and one of the display areas is arranged on one side of one long side of the waiting transfer area and the operation area;
- or, two the display areas are configured in one waiting transfer area and one operation area, and one of the display areas is respectively arranged on each side of two long sides of the waiting transfer area and the operation area.
