[0027] Referring to Figures 1 - 5 , this embodiment proposes a wheat and corn germination test device, which includes a box body 1. Inside the box body 1, a first horizontal plate 4 and a second horizontal plate 5 are arranged in parallel. At the top inside the box body 1, a top spring 8 is connected, and at the bottom of the top spring 8, a top block 7 is connected. A through hole is opened in the middle of the first horizontal plate 4, and the middle of the top block 7 is stuck to the through hole through the top spring 8. Vertically connected to the middle of the second horizontal plate 5 is a vertical partition 6, and the bottom of the vertical partition 6 is connected to the bottom of the box body 1. The vertical partition 6 and the second horizontal plate 5 divide the box body 1 into two breeding spaces. At the connection position of the top of the vertical partition 6 and the second horizontal plate 5, a groove 61 is opened, and the bottom of the top block 7 contacts the bottom of the groove 61. The bottom of the groove 61 is flush with the bottom of the fluorescent lamp 94, and the fluorescent lamp 94 can pass through the groove 61 and shuttle in the two breeding spaces. The side of the top block 7 is in the shape of an inverted isosceles triangle, and the top angle of the isosceles triangle abuts against the bottom of the groove 61. The bottom of the second horizontal plate 5 is slidably connected to the fluorescent lamp 94, and the fluorescent lamp 94 is connected to the second horizontal plate 5 through a sliding assembly 9.
[0028] The sliding component 9 in this embodiment includes a through groove formed in the second cross plate 5 and communicating with two breeding spaces. Two racks 51 are oppositely connected to the through groove. Sliding grooves 52 are respectively formed at the bottoms of the two racks 51 along the direction of the racks 51. Two sliding blocks 96 are slidably connected in the two sliding grooves 52. A sliding frame 91 is connected between the two sliding blocks 96. The sliding frame 91 is perpendicularly provided with a through space. Two driving gears 92 are rotatably connected in the through space. The two driving gears 92 are respectively engaged with the racks 51 on both sides. The bottom of the driving gear 92 is connected to a transmission shaft 95, and the bottom of the transmission shaft 95 is connected to a driving motor 93. The driving motor 93 can drive the driving gear 92 to rotate, so that the sliding blocks 96 on the sliding frame 91 move horizontally along the sliding grooves 52. Since the pressing block 7 is beveled, when the sliding frame 91 moves to contact the top block and then moves again, it can lift the pressing block 7. The pressing block 7 moves upward. After the sliding frame 91 passes, under the action of the pressing spring 8, the pressing block 7 can fall back and then continue to press against the groove 61. At this time, the fluorescent lamp 94 moves from one breeding space to another breeding space.
[0029] A culture box 2 is detachably installed in the breeding space. A pH sensor and a humidity sensor are installed in the culture box 2. A box door 3 is rotatably connected to each side of the box body 1. The widths of the two box doors 3 are greater than the width of the breeding space. A control driving motor 93 and a display screen 10 for displaying humidity and pH are installed on the box door 3.
[0030] Usage method:
[0031] First, the fluorescent lamp 94 is located in one breeding space. Turn on the fluorescent lamp 94 and turn on the driving motor 93 through the display screen 10 to make the fluorescent lamp 94 move slowly horizontally. At this time, the movement of the simulated daylight on this side makes the seeds evenly irradiated in all directions, and the other breeding space simulates the state without daylight at night; when the sliding frame 91 contacts the pressing block 7 and slowly lifts the pressing block 7, at this time, the rising of the sun and the gradual strengthening of the daylight are simulated in the other breeding space; when the fluorescent lamp 94 passes through the pressing block 7, the pressing block 7 gradually falls. At this time, the setting of the sun and the gradual weakening of the daylight are simulated in the breeding space on this side, and the process of the sun rising in the east and setting in the west starts on the other side.
[0032] Although the specific implementation manners of the utility model are described above in conjunction with the drawings, it is not a limitation to the protection scope of the utility model. Based on the technical solution of the utility model, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the utility model.
