Description

Technical Field

[0001] This utility model belongs to the field of corn planting technology, and specifically relates to a seedling cultivation rack for corn after selection and breeding. Background Technology

[0002] After corn seeds germinate into seedlings, they need to be selected based on their growth; seedlings with poor growth are discarded. To ensure the selected corn seedlings grow healthier, we first place nutrient-rich, fresh soil on new cultivation racks, and then plant the selected superior seedlings in the new soil for further cultivation. After the seedlings have grown for a period of time, we transplant them into open fields. However, after transplanting the cultivated corn into the fields, some corn plants exhibited malnutrition.

[0003] After ensuring the soil in the field met the requirements for corn growth, we found that during the transplanting of corn seedlings grown on the cultivation racks to the field, the roots of some corn seedlings were cut off, and the cut roots could not absorb enough nutrients. The root cause of this problem is that the planting troughs on the cultivation racks in the existing technology cannot be disassembled, so we must remove or separate the soil from the planting troughs by cutting them, which inadvertently cuts off some of the corn seedling roots.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1:

[0032] The corn seedling cultivation rack provided in this embodiment includes two uprights 1 and a planting trough. The planting trough is formed by a left side plate 2, a right side plate 3, a front side plate 4, a rear side plate 5 and a bottom plate 6. Soil for cultivating corn is placed in the planting trough.

[0033] A first connecting rod 7 is integrally formed on the left end face of the left side plate 2, and a second connecting rod 8 is integrally formed on the right end face of the right side plate 3. Each of the first connecting rod 7 and the second connecting rod 8 is connected to a slider 9, and there are multiple first connecting rods 7 and multiple second connecting rods 8 connected to other sliders 9. The two sliders 9 are slidably mounted on the two pillars 1, allowing the left side plate 2 and the right side plate 3 to slide between the two pillars 1.

[0034] A locking device is also installed between the slider 9 and the column 1. When the locking device is locked, the slider 9 cannot slide up and down on the column 1. When the locking device is unlocked, the slider 9 can slide up and down on the column 1.

[0035] Two vertical sliding grooves, one in front and one behind, are formed on the right end face of the left side plate 2 and the left end face of the right side plate 3, respectively. That is, both the left side plate 2 and the right side plate 3 have two vertical sliding grooves, distributed one in front and one behind on each side plate. A through groove is formed at the bottom of both the left side plate 2 and the right side plate 3, located at the bottom end of the vertical sliding grooves. The base plate 6 is slidably inserted into the through groove, the front side plate 4 is slidably inserted into the two vertical sliding grooves located on the front side, and the rear side plate 5 is slidably inserted into the two vertical sliding grooves located on the rear side. The bottom ends of the front side plate 4 and the rear side plate 5 overlap the base plate 6. Specifically, the left and right ends of the front side plate 4 are slidably inserted into the vertical sliding grooves on the front side of the left side plate 2 and the right side plate 3, respectively, and the left and right ends of the rear side plate 5 are slidably inserted into the vertical sliding grooves on the rear side of the left side plate 2 and the right side plate 3, respectively.

[0036] With the above structure, the entire planting trough is first locked at a suitable height using locking devices. Then, selected corn seedlings are planted in the soil within the planting trough. Once the seedlings have grown to a certain size, planting pits are dug in the field. The entire assembly is then moved to the field, the locking devices are released, and the planting trough is slid down to align with the planting pit. The bottom plate 6, front side plate 4, and rear side plate 5 are then removed, and the two uprights 1 are moved to the sides. The soil in the planting trough falls into the planting pit under its own weight, and subsequent backfilling and other operations are then performed. Using the seedling cultivation frame provided in this embodiment, when transplanting corn seedlings from the planting trough to the field, only the planting trough needs to be disassembled; there is no need to cut the soil within the trough. This avoids severing the roots of the corn seedlings, thus ensuring their healthy growth after transplanting.

[0037] Optionally, ear plates 11 are provided at both ends of the base plate 6. Each ear plate 11 has a square hole into which a locking pin 12 is inserted, with both ends of the locking pin 12 extending out. The two locking pins 12 are respectively attached to the left end face of the left side plate 2 and the right end face of the right side plate 3. Thus, the base plate 6 is securely connected to the bottom of the left side plate 2 and the right side plate 3 using the two locking pins 12. When it is necessary to remove the base plate 6, the locking pins 12 can be removed.

[0038] An optional implementation of this embodiment is as follows: The locking component is a bolt 10, with a through hole on the column 1 and a threaded hole on the slider 9. The bolt 10 passes through the through hole and is screwed into the threaded hole. When the bolt 10 is tightened, the slider 9 is locked onto the column 1. When the bolt 10 is loosened and removed from the through hole, the slider 9 can slide up and down on the column 1.

[0039] A shim 13 is also installed between the nut of the bolt 10 and the column 1. The surface of the shim 13 that contacts the column 1 has anti-slip texture. When the bolt 10 is tightened, the shim 13 is pressed against the outer wall of the column 1. The anti-slip texture increases the coefficient of friction, preventing the shim 13 from shifting. Furthermore, the shim 13 increases the pressure application area, thus making the bolt 10 more securely lock the slider 9 onto the column 1. The shim 13 has a through hole through which the bolt 10 passes.

[0040] Optionally, a vertical long groove is formed on the column 1. The pad 13 includes a first square and a second square. The second square is located in the middle of the first square to form a T-shaped structure. The second square is inserted into the long groove, and the first square is tightly attached to the column 1. A through hole passes through the first square and the second square. In this way, the long groove positions the pad 13 for installation. The column 1 includes a square column 101 and a guide rail 102. The long groove is located on one outer wall of the square column 101, and the guide rail 102 is fixed on the other outer wall of the square column 101. The guide rail 102 is parallel to the long groove. A track groove is formed on the slider 9, and the guide rail 102 is slidably inserted into the track groove. In this way, the slider 9 can only slide up and down on the column 1 and cannot rotate. A through hole passes through the square column 101 and the guide rail 102, and a screw hole is formed on the side wall of the track groove.

[0041] An optional implementation of this embodiment is as follows: A support plate 14 is fixed at the bottom of the square column 101. A ground plug 15 is detachably installed on the support plate 14. With the help of the ground plug 15, when the entire cultivation frame is placed in the field, the ground plug 15 is inserted into the soil of the field. When the planting trough is disassembled, it can be ensured that the entire cultivation frame will not tip over.

[0042] Specifically, the support plate 14 has threaded holes, and the floor plug 15 is screwed into the threaded holes. This allows the user to easily install and remove the floor plug 15. When the floor plug 15 is no longer needed, it can be removed.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
