Specific embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment: Refer to Figures 1-6 A corn breeding germination device shown, including a germination box 1. A water pump for pumping water is provided outside the germination box 1, and three groups of water spraying pipes are provided inside the germination box 1. The water inlet of the water pump is connected to a water supply device, and the water outlet of the water pump is connected to the water spraying pipes. Through the design of the above structure, the seedlings on the germination tray 9 placed inside the germination box 1 are supplemented with nutrient solution and water source; Hook-shaped rails 4 are provided on the inner wall of the germination box 1. Every two rails are in a group, and a total of three groups are provided vertically. A jacking mechanism that is slidably connected to the bottom of the germination tray 9 is slidably connected to the rails 4, and an auxiliary mechanism for assisting in removing seedlings is provided in each germination groove 92 of the germination tray 9. The auxiliary mechanism cooperates with the top-out mechanism to assist the staff in taking seedlings.

[0025] Lifting mechanism: The bottom plate 6 is located below the germination tray 9, and connecting grooves 91 with a "convex" - shaped cross - section are provided at the four corners of the germination tray 9. A connecting piece 7 is threadedly connected to the top of the bottom plate 6. The connecting piece 7 is slidably connected to the connecting groove 91, and part of the thread is provided at the top of the connecting groove 91. This thread is threadedly connected to a nut. A reset spring 10 for resetting is press - fitted between the connecting piece 7 and the nut. Therefore, through the structural design in the connecting groove 91, after the germination tray 9 is pressed downward, the push rod 62 on the bottom plate 6 cooperates with the auxiliary mechanism in the germination groove 92 to push the auxiliary mechanism upward, releasing the limit on the seedlings. After the seedlings are taken away, and then after releasing the downward pressure on the germination tray 9, the compressed reset spring 10 exerts force, and with the bottom plate 6 as the base, the germination tray 9 is lifted, separating the two.

[0026] To avoid, during the seedling - raising process, the germination tray 9 moving downward due to the replenishment of nutrient solution and water source, thus activating the auxiliary mechanism. Therefore, a horizontal limiting hole 71 is provided on the connecting piece 7, and a pin 8 is inserted into the limiting hole 71 (the limiting hole 71 is located below the germination tray 9 in the normal state). The pin 8 limits the position to prevent the germination tray 9 from moving downward.

[0027] A guiding groove 61 is provided on the outer wall of the bottom plate 6. The guiding groove 61 is adapted to the rail 4. Through the cooperation of the guiding groove 61 and the rail 4, the bottom plate 6 is placed on the rail 4 and abuts against the push - plate 2 inside the germination box 1, and at the same time, the push - plate 2 compresses the push - out spring 3. This process causes the push - out spring 3 to be compressed. To prevent the bottom plate 6 from being pushed out, a cam - shaped limiting member 5 is hinged at the end of the rail 4. Under the action of the push - out spring 3, the bottom plate 6 abuts against the limiting member 5 outward. Thus, through the cooperation of the above - mentioned structures, when the bottom plate 6 needs to be taken out, the limit of the limiting member 5 is released, and the push - out spring 3 pushes the push - plate 2 out to assist in taking out.

[0028] Auxiliary mechanism: A leakage plate 15 is slidably connected to the bottom of the germination tank 92. The function of the leakage plate 15 is to support the seedlings from the bottom. At the same time, the leakage plate 15 is slidably connected in the germination tank 92 and can push out the seedlings. On the left and right inner walls of the germination tank 92, chute 93s (the chute 93s are trapezoid-like right-angle structures) are provided. A hole communicating with the outside is provided at the top inside the chute 93. The hole is inclined so that the guide rod 13 can be inserted into the inside of the chute 93. A connecting rod 12 is slidably connected to the guide rod 13. One end of the connecting rod 12 is C-shaped and is buckled on the guide rod 13 (the connecting rod 12 with a C-shaped end is convenient for replacement during subsequent maintenance). The other end is connected to an L-shaped adjusting plate 11. Therefore, during the upward movement of the leakage plate 15, the adjusting plate 11 is pushed upward. The upward-moving adjusting plate 11 gradually approaches the inner wall of the germination tank 92 through the cooperation between the connecting rod 12 and the guide rod 13 and finally fits between the two, increasing the distance between the two groups of adjusting plates 11 so as to take out the seedlings. And a return spring 14 is press-fitted between the top surface of the connecting rod 12 and the chute 93. After the seed taking is completed, automatic reset can be carried out.

[0029] During the above use process, in order to prevent the need for staff to constantly press the germination tray 9 against the bottom plate 6, a U-shaped clamping member can be used, and its inner top surface and inner bottom surface respectively abut against the top surface of the pressed germination tray 9 and the bottom surface of the bottom plate 6.

[0030] The working principle of this utility model: Align the guiding groove 61 on the bottom plate 6 with the rail 4, then push the bottom plate 6 inward and abut against the push plate 2, then squeeze the push spring 3 connected to the push plate 2, then rotate the limiting member 5, limit the bottom plate 6 through the limiting member 5, then under the action of the water pump, pump out the water from the water supply equipment and send it into the spray pipe to spray the seedlings on the germination tray 9. After the spraying task is completed, rotate the limiting member 5 again. After the limit is released, under the action of the push spring 3, push the bottom plate 6 outward through the push plate 2 to assist the staff in taking out the bottom plate 6;

[0031] After removing the bottom plate 6, by removing the pin 8 in the limit hole 71 of the connecting member 7, after releasing the limit of the germination tray 9 by the pin 8, by squeezing the germination tray 9 downward, the connecting member 7 slides in the connecting groove 91 and squeezes the return spring 10. After the germination tray 9 and the bottom plate 6 are fitted, a U-shaped clamping member is used to limit the germination tray 9 and the bottom plate 6. During this process, the push rod 62 at the top of the bottom plate 6 pushes the leakage plate 15 in the germination groove 92 upward, and the leakage plate 15 pushes the adjusting plate 11 to slide upward. Under the action of the connecting rod 12, while the adjusting plate 11 moves upward, the connecting rod 12 slides on the guide rod 13, and the adjusting plate 11 gradually approaches the inner wall of the germination groove 92 and fits with it. Subsequently, the limit on the seedlings is released so that the staff can take out the seedlings. Then, the U-shaped clamping member is removed to release the limit between the bottom plate 6 and the germination tray 9. Subsequently, under the action of the return spring 10, the two are separated, and with the assistance of the return spring 14 on the guide rod 13, the adjusting plate 11 is reset so that new seedlings can be placed again.
