Description

Technical Field

[0001] The utility model relates to the technical field of breeding devices, in particular to a breeding device for corn cultivation that is convenient for seedling extraction. Background Technique

[0002] In order to increase the survival rate of corn and improve the growth rate of corn, generally, corn seedlings are raised. At present, when raising corn seedlings, a seedling tray, which is an easy-to-operate device, is mostly used to raise corn seedlings.

[0003] As in the prior art, a patent with the patent authorization announcement number CN212786800U discloses a seedling tray, which includes a tray body. A number of downwardly concave holes are provided on the tray body. The bottom of the hole is recessed inward to form a groove. A ventilation hole is provided at the bottom of the hole, and the ventilation hole communicates with the inside of the hole. Fixing grooves are provided on the upper four peripheral edges of the hole, and the fixing grooves communicate two adjacent holes. A connecting plate is fixedly provided at the lower part of the tray body, and the connecting plate is fixedly arranged between the bottoms of two adjacent holes along the short side direction of the tray body. Support plates are fixedly provided on both sides of the lower part of the tray body, and a limiting plate is fixedly provided at the lower part of the tray body. The limiting plate is fixedly arranged between the support plate and the hole close to the support plate side; when in use, the lower end of the connecting plate can be snapped into the fixing groove on the upper tray body to fix the tray bodies of the upper and lower two seedling trays. With the cooperation of the support plate and the connecting plate, the tray body has strong supporting force and is more stable when being carried, and the water distribution of the tray body can be made more uniform when in use.

[0004] Although the water distribution of the tray body can be made more uniform when the seedling tray in the above patent is in use, the seedling tray has certain defects; since the roots and stems of corn seedlings are relatively numerous, sometimes the roots of corn seedlings will be entangled in the water-permeable holes at the bottom of the seedling tray. This leads to that after the seedling raising is completed, in order to take out the corn seedlings from the seedling tray, the roots of the corn seedlings must be carefully removed from the water-permeable holes, and then the corn seedlings can be completely taken out for cultivation. If brute force is used to directly pull, it is easy to cause the roots of the corn seedlings to break, thereby damaging the corn seedlings. Therefore, the existing seedling trays need to be improved. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a breeding device for corn cultivation that is convenient for seedling extraction to solve the problems raised in the background technique and make it easier to take out corn seedlings.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 of the embodiments.

[0019] Please refer to Figures 1 - 3 , a breeding device for corn cultivation that facilitates seedling extraction, including a lower layer frame 1. A plurality of lower side plates 4 are placed in the middle position of the lower layer frame 1. A positioning frame 5 is fixedly connected to the outer wall of the lower side plate 4. The upper end of the lower side plate 4 is slidably connected to an upper side plate 6. A push plate 9 is fixedly connected to the lower end inside the upper side plate 6. The lower end inside the lower side plate 4 is hinged to a bottom plate 7. A water permeable hole is opened in the middle position between the two bottom plates 7. The bottom plate 7 is located above the push plate 9.

[0020] In the breeding device for corn cultivation that facilitates seedling extraction in the present utility model, when it is necessary to extract corn seedlings, only the upper side plate 6 needs to be lifted upward. During the upward movement of the upper side plate 6, the push plate 9 will push the bottom plate 7 upward, causing the bottom plate 7 to flip upward, thereby expanding the diameter of the water permeable hole on the bottom plate 7. In this way, even if the roots of the corn seedlings are entangled in the water permeable hole, it is easy to extract them, making the seedling extraction of the breeding device simpler and more convenient.

[0021] As Figure 3 shown, placement grooves 8 are opened at both ends of the bottom plate 7. A top block 10 that matches the placement groove 8 is fixedly connected to the middle position of the push plate 9.

[0022] Specifically, during the normal seedling raising process, both ends of the bottom plate 7 will rest on the top block 10 to prevent the culture medium from leaking out from the bottom. When transplanting by extracting the corn seedlings, since the roots of the corn seedlings are entangled in the culture medium, the culture medium and the corn seedlings form a whole. During the upward movement of the upper side plate 6, it will drive the culture medium and the corn seedlings to move upward together. At the same time, the top block 10 will push the bottom plate 7 upward, causing the bottom plate 7 to rotate, facilitating the roots of the corn seedlings to disengage from the water permeable hole. Finally, only the corn seedlings need to be taken out between the upper side plates 6.

[0023] As Figure 1 and Figure 2 shown, a middle layer frame 2 is provided at the top of the lower layer frame 1. The middle layer frame 2 is located below the upper side plate 6 and matches the edge at the top of the upper side plate 6. The upper side plate 6 is placed on the middle layer frame 2. Therefore, when extracting seedlings, multiple groups of lower side plates 4 and upper side plates 6 can be directly separated through the middle layer frame 2 at one time, making the operation simpler and more convenient.

[0024] As Figure 1 and Figure 2As shown, an upper frame 3 is provided at the top of the middle frame 2. The upper frame 3 is located above the upper side plate 6, and the upper frame 3 matches the edge at the top of the upper side plate 6. After the upper frame 3 and the middle frame 2 are connected to each other, the upper side plate 6 will be fixed to prevent the upper side plate 6 from moving during the seedling cultivation process and causing damage to the corn roots.

[0025] As Figure 1 and Figure 2 shown, strong magnetic blocks are fixedly connected inside the lower frame 1, the middle frame 2, and the upper frame 3. The lower frame 1, the middle frame 2, and the upper frame 3 are connected and fixed to each other through the strong magnetic blocks, which is convenient for disassembly at any time. At the same time, the edges at the top of the positioning frame 5 and the upper side plate 6 are made of iron materials, making it easier to fix the lower side plate 4 and the upper side plate 6 inside the lower frame 1, the middle frame 2, and the upper frame 3.

[0026] As Figure 3 shown, the sides of the lower side plate 4 and the upper side plate 6 are both inclined. The inclined lower side plate 4 and upper side plate 6 make it easier to take out the seedlings.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
