Description

Technical Field

[0001] This utility model relates to the field of seedling tray technology, specifically a bottomless rice seedling tray for rice cultivation. Background Technology

[0002] The seedling tray is an indispensable component of rice transplanters. Its main function is to realize the seedling raising process of rice seedlings. The seedling tray is made of polyvinyl chloride as raw material and is processed by special process formula to form a vacuum. Different transplanters are equipped with seedling trays of different specifications, usually divided into hard seedling trays and soft seedling trays.

[0003] A search revealed Chinese patent application number CN202322350199.8, which discloses a bottomless rice seedling tray for rice cultivation. The tray includes a main body, a placement groove inside the main body, a limiting unit inside the placement groove, and an adjustment unit at the bottom of the limiting unit. The limiting unit includes a dividing component at the top of the placement groove and a disassembly component at the bottom of the dividing component. The adjustment unit includes a rotating component at the bottom of the disassembly component and an adjustment component on the side of the rotating component.

[0004] The bottom of the aforementioned bottomless rice seedling tray for rice cultivation does not have drainage holes or other structures. When using the tray to cultivate rice seedlings, water will accumulate inside the tray, causing the roots of the rice seedlings to be soaked in the water for an extended period of time, resulting in root rot. Therefore, this utility model provides a bottomless rice seedling tray for rice cultivation. Utility Model Content

[0011] Preferably, a support foot pad is fixedly installed at the bottom of the U-shaped disk.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a bottomless rice seedling tray for rice cultivation, which has the following beneficial effects:

[0014] This bottomless rice seedling tray for rice cultivation uses a combination of a U-shaped tray, groove, drainage holes, slot, insert plate, grid support plate, seedling tray, and handle groove. In use, the insert plate is inserted into the slot, then the grid support plate is placed into the seedling tray, and the seedling tray is laid on the grid support plate. The seedlings are then sown using a seeder. Excess nutrient solution or water sprayed during cultivation flows from the holes at the bottom of the seedling tray into the groove and out through the drainage holes, effectively preventing water accumulation in the seedling tray and thus preventing root rot in the seedlings. The slot, insert plate, and seedling tray allow for easy removal of the seedlings by pulling out the insert plate and then removing the seedling tray. The rice seedlings are then laid down on the tray, facilitating the removal of the seedlings from the plastic film. Attached Figure Description

[0017] In the diagram: 1. U-shaped disk 2. Groove 3. Drain hole 4. Slot 5. Insert plate 6. Grid support plate 7. Incubation floppy disk 8. Handle groove 9. Support foot pad. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This utility model provides a technical solution: It includes a U-shaped disk 1, with a groove 2 formed at the bottom inner part of the U-shaped disk 1. The groove 2 is horizontally and vertically interconnected, forming a mesh. Several guide holes 3 are formed inside both the groove 2 and the U-shaped disk 1. Slots 4 are formed on both sides of the inner wall of the U-shaped disk 1, with insert plates 5 inserted into the slots 4. A grid support plate 6 is provided inside the U-shaped disk 1, and a cultivation floppy disk 7 is installed above the grid support plate 6. Through the coordinated arrangement of the U-shaped disk 1, groove 2, guide holes 3, slots 4, insert plates 5, grid support plate 6, cultivation floppy disk 7, and handle groove 8, in use, the insert plate 5 is inserted into the slot 3, and then the grid support plate 6 is placed into the cultivation disk. The seedling tray 7 is laid on the grid support plate 6, and then the seedling tray is sown by the seeder. Excess nutrient solution or water sprayed during cultivation will flow from the bottom holes of the seedling tray 7 into the groove and out through the guide hole, thus effectively preventing water accumulation in the seedling tray and causing seedling root rot. The surface of the insert plate 5 has a through handle groove 8. With the cooperation of the slot 4, insert plate 5 and seedling tray 7, the insert plate 5 is pulled out when in use, and then the seedling tray 7 is taken out. Then the rice seedlings on the tray are turned down, which makes it convenient for the cultivation personnel to remove the seedlings from the film. The U-shaped tray 1 and the insert plate 5 are used to form the whole seedling tray. The bottom of the U-shaped tray 1 is fixedly installed with a support foot pad 9.

[0020] In summary, this bottomless rice seedling tray for rice cultivation is designed with a U-shaped tray 1, a groove 2, a guide hole 3, a slot 4, an insert plate 5, a grid support plate 6, a seedling tray 7, and a handle groove 8. During use, the insert plate 5 is inserted into the slot 3, the grid support plate 6 is placed into the seedling tray, and the seedling tray 7 is laid on the grid support plate 6. Then, the seedling tray is sown using a seeder. Excess nutrient solution or water sprayed during cultivation flows from the holes at the bottom of the seedling tray 7 into the groove and out through the guide hole, effectively preventing water accumulation in the seedling tray and thus preventing root rot in the seedlings. The slot 4, insert plate 5, and seedling tray 7 allow for easy removal of the seedlings by pulling out the insert plate 5 and then removing the seedling tray 7. The rice seedlings on the tray are then laid down, facilitating the removal of the seedlings from the film by the cultivation personnel.
