Description

Technical Field

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

[0002] In rice cultivation, seedling trays are an important tool for raising seedlings. Rice seeds are evenly sown on specially prepared nutrient soil within the trays, and placed in a suitable environment, the seeds germinate and grow rapidly. The trays facilitate centralized management, provide a stable growing space for the seedlings, effectively control water and nutrients, and cultivate uniform and robust seedlings, laying a solid foundation for efficient transplanting and improved rice yield and quality.

[0003] Existing rice seedling trays are typically made of soft PVC plastic, which is prone to deformation and damage due to external pressure or impact during use. This not only affects the normal use of the tray and shortens its lifespan, but may also cause the seedlings inside to be squeezed, damaging the seedling growth environment and thus affecting the germination rate and growth quality of the seedlings.

[0004] Furthermore, some seedling trays currently have poor air permeability. Seedlings in the trays need sufficient air for respiration, but poor air permeability leads to poor air circulation, accumulation of waste gases such as carbon dioxide, and insufficient oxygen supply. This hinders root respiration, affects nutrient absorption and normal growth and development, resulting in slow and weak seedling growth and a reduction in the overall quality of the seedlings.

[0005] Therefore, we have made improvements to this and proposed a seedling tray for rice cultivation. Utility Model Content

[0035] To address the technical problems in the background section, the following rice seedling tray is provided:

[0036] Combination Figure 1 - Figure 5 As shown, the present invention provides a rice seedling tray for planting, comprising a tray body 1, with protruding strips 2 fixedly installed on both sides of the bottom of the tray body 1, and a sliding frame 3 slidably connected inside the tray body 1, with a tray plate 4 disposed inside the sliding frame 3, and several through holes 5 evenly opened on the surface of the tray plate 4; the tray body 1 includes a base strength bearing layer 101, a reinforcing layer 102 and a protective layer 103, with the reinforcing layer 102 disposed outside the base strength bearing layer 101 and the protective layer 103 disposed outside the reinforcing layer 102.

[0037] In this embodiment, the protruding strips 2 fixedly installed on both sides of the bottom of the tray body 1 provide stable support and anti-slip function during placement, ensuring the tray is placed stably and facilitating the stacking of the tray body 1 during storage. The sliding frame 3 with internal sliding connection facilitates the subsequent removal of seedlings planted on the tray 4. Several through holes 5 evenly opened on the surface of the tray 4 facilitate the circulation of water and air, creating a good environment for seedling growth. The multi-layer structure of the tray body 1, consisting of a base load-bearing layer 101, a reinforcing layer 102, and a protective layer 103, enhances the strength and durability of the tray.

[0038] As a preferred embodiment, based on the above method, the base strength bearing layer 101 is further made of high-density polyethylene material.

[0039] In this embodiment: High-density polyethylene has excellent mechanical properties, with high strength and good toughness, which enables the base strength bearing layer 101 to withstand greater pressure, providing a stable growth environment for the seedlings on the tray, effectively resisting external squeezing and collision during handling and storage, and avoiding the normal development of seedlings due to tray deformation.

[0040] Meanwhile, the material's excellent chemical corrosion resistance and wear resistance can resist the erosion of various common chemicals, further ensuring the pallet's performance and durability, and greatly extending the pallet's service life.

[0041] As a preferred embodiment, based on the above method, the reinforcing layer 102 is further made of glass fiber reinforced plastic, and the reinforcing layer 102 is tightly bonded to the outside of the base load-bearing layer 101.

[0042] In this embodiment, glass fiber reinforced plastic effectively improves the strength of the pallet. It has an extremely high strength-to-weight ratio, ensuring that the reinforcing layer 102 is sufficiently strong, effectively enhancing the overall compressive strength of the pallet and resisting external impacts, while not excessively increasing the weight of the pallet, making it convenient for handling and operation.

[0043] The reinforcement layer 102 is tightly bonded to the outside of the base strength load-bearing layer 101. Together, the base strength load-bearing layer 101 provides basic support for the tray, while the reinforcement layer 102 further strengthens the structure, providing reliable and durable load-bearing protection for rice seedlings.

[0044] As a preferred embodiment, based on the above method, the protective layer 103 is further made of polyurethane coating, and the protective layer 103 is uniformly coated on the outer surface of the reinforcing layer 102.

[0045] In this embodiment, the polyurethane coating possesses excellent protective properties, effectively resisting corrosion from external factors such as ultraviolet rays, rain, and acids and alkalis. The polyurethane coating, with its good weather resistance and chemical corrosion resistance, protects the reinforcing layer 102 from damage, thereby maintaining the overall stability of the pallet structure.

[0046] Moreover, the coating also has a certain degree of flexibility and wear resistance, which can reduce wear and extend the service life of the pallet when it rubs against external objects during pallet handling and placement.

[0047] As a preferred embodiment, based on the above method, the tray body 1 is further provided with first ventilation holes 6 on both sides, and handle grooves 11 are provided on the other two sides, and second ventilation holes 7 are uniformly provided on both sides of the sliding frame 3.

[0048] In this embodiment, the first vent 6 and the second vent 7 work together to greatly promote air circulation inside the tray, creating a more suitable microenvironment for seedling growth. Handle slots 11 on both sides of the tray body allow operators to easily reach their hands for handling and movement.

[0049] As a preferred embodiment, based on the above method, a support frame 8 is further fixedly installed inside the sliding frame 3, and a tray 4 is disposed on the upper side of the support frame 8, forming an engaging structure between the tray 4 and the sliding frame 3.

[0050] In this embodiment: the support frame 8 provides a reliable support platform for the tray 4, ensuring that the tray 4 can be placed stably, thereby ensuring a stable growth environment for the seedlings planted on it. The tray 4 and the sliding frame 3 form a locking structure, which facilitates the disassembly of the tray 4 and the removal of the seedlings.

[0051] As a preferred embodiment, based on the above method, the bottom of the tray body 1 is provided with a plurality of drainage holes 9, and the plurality of drainage holes 9 are connected to each other through drainage grooves 10.

[0052] In this embodiment: when the seedlings are overwatered or when it rains, the excess water can quickly seep down through the through holes 5 on the tray 4 and collect at the bottom of the tray body 1. Multiple drainage holes 9, together with the drainage groove 10, can quickly drain the accumulated water from the tray, preventing water from accumulating in the tray and causing the seedling roots to rot.

[0053] As a preferred embodiment, based on the above method, the sliding frame 3 is further provided with handles 12 slidably connected to both sides of the sliding frame 3, and the sliding frame 3 is provided with grooves 13 on both sides of the sliding frame 3. The sliding grooves 13 are slidably connected to the sliding strips 14, and both ends of the handles 12 are fixedly installed on the upper surface of the sliding strips 14.

[0054] In this embodiment, the handle 12 is designed as a telescopic structure. When it is necessary to move the sliding frame 3 or take out the seedlings on the tray 4, the operator can pull up the handle 12 to take out the seedlings in the sliding frame 3. When not in use, it can be retracted downwards. The handle 12 will not protrude outside the tray, making it easy to stack the trays and preventing the handle 12 from causing any obstruction.

[0055] Specifically, the working principle of this solution is as follows:

[0056] The raised strips 2 on both sides of the bottom of the tray body 1 provide stable support and anti-slip function, and facilitate stacking when not in use. The internal sliding frame 3 makes it easy to remove seedlings from the tray 4, and the through holes 5 on the surface of the tray 4 facilitate the circulation of water and air. The tray body 1 is composed of a multi-layer structure. The base load-bearing layer 101 is made of high-density polyethylene material, which has high strength and good toughness and can withstand compression and impact. The reinforcing layer 102 is made of glass fiber reinforced plastic, which is tightly bonded to the outside of the base load-bearing layer 101 to enhance the compressive strength without adding too much weight. The protective layer 103 is a polyurethane coating, which is evenly applied to the outside of the reinforcing layer 102 to resist external corrosion and wear.

[0057] The first vent 6 and the second vent 7 promote internal air circulation, while the handle groove 11 facilitates handling. The support frame 8 provides support for the tray 4, and the two interlock for easy disassembly. The bottom drainage hole 9 and the drainage channel 10 are connected to quickly drain accumulated water. The handles 12 on both sides of the sliding frame 3 are designed as telescopic structures, which extend and retract by sliding the sliding strip 14 within the sliding groove 13. They can be pulled up for easy operation when in use and retracted when not in use, without affecting the stacking of trays, providing a stable and suitable environment for the growth of rice seedlings.

[0058] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0059] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
