DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 The utility model provides a technical solution: a rice seedling hydroponic device, comprising a base 1, a support plate 2, a water tank 3, a positioning bar 4, a seedling tray 5, a support block 6, a limit rod 7, a mounting bar 8, a waterproof spring 9, a water tank 10, a mounting plate 11, a heating lamp 12, a connecting ear 13, a threaded rod 14, a first motor 15, a first connecting piece 16, a belt 17, a second connecting piece 18, a water inlet 19, a connecting shaft 20, a second motor 21, a stirring rod 22, a stirring blade 23 and a hose 24. When the rice seedling hydroponic device is used, Figure 1 and Figure 4 The limiting structure includes a positioning bar 4, a support block 6, a limiting rod 7, a mounting bar 8 and a waterproof spring 9. Since the positioning bar 4 is engaged with the limiting rod 7 in the hollow structure of the support block 6, the mounting bar 8 and the support block 6 form a telescopic structure, and the left and right ends of the seedling tray 5 are integrally connected with the support block 6;

[0030] Therefore, the seedling tray 5 is nested and connected inside the water tank 3, so that the support block 6 symmetrically arranged on the left and right is overlapped on the upper end of the positioning bar 4, and the installation bar 8 is pulled to engage the limit rod 7 in the hollow structure between the positioning bar 4 and the support block 6. The waterproof spring 9 is set to pull the installation bar 8 downward so that the lower end of the installation bar 8 is attached to the upper end of the support block 6;

[0031] The liquid in the water tank 10 enters the water tank 3 through the hose 24, and the liquid in the water tank 3 is transferred to the seedlings in the seedling tray 5 through the porous structure at the bottom of the seedling tray 5, so that the position of the seedling tray 5 can be easily limited;

[0032] like Figure 1 and Figure 5, since the lower end of the connecting shaft 20 is fixedly connected with the stirring rod 22 at an equal angle, the outer surface of the middle end of the connecting shaft 20 is evenly inlaid with the stirring blade 23, the stirring blade 23 and the stirring rod 22 are both in a rotating structure inside the water tank 10 through the connecting shaft 20;

[0033] Therefore, clean water and nutrient solution are poured into the water tank 10 through the water inlet 19, and the second motor 21 drives the connecting shaft 20 to rotate inside the water tank 10 when working, so that the connecting shaft 20 drives the stirring rods 22 arranged at equal angles and the stirring blades 23 arranged evenly to rotate;

[0034] The stirring rods 22 and the stirring blades 23 arranged at equal angles are driven to stir and mix the liquid inside the water tank 10, so that the nutrient elements will not precipitate, thereby facilitating the nutrient elements to be fully mixed in the clean water and preventing different liquid concentrations;

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The height adjustment structure includes a connecting ear 13, a threaded rod 14, a first motor 15, a first connecting member 16, a belt 17 and a second connecting member 18. Since the inner end of the mounting plate 11 is evenly spaced with the heating lamps 12, the position of the mounting plate 11 corresponds to the position of the water tank 3 one by one, the first connecting member 16 and the second connecting member 18 are connected by the belt 17, and the front longitudinal section of the first connecting member 16 and the second connecting member 18 is an "I"-shaped structure, the diameter of the first connecting member 16 is greater than the diameter of the second connecting member 18, and the mounting plate 11 is a lifting structure on the upper side of the base 1 through the threaded rod 14 and the connecting ear 13;

[0036] Therefore, in the process of raising seedlings, in order to ensure the required temperature in raising seedlings, the first motor 15 needs to work to drive the left threaded rod 14 to rotate, and when the threaded rod 14 rotates, it drives the first connecting member 16 to rotate, and when the first connecting member 16 rotates, it drives the second connecting member 18 to rotate through the belt 17, so that the second connecting member 18 drives the right threaded rod 14 to rotate at the right end of the base 1, and when the left and right sets of threaded rods 14 rotate, the left and right symmetrically arranged connecting ears 13 move up and down, so that the mounting plate 11 moves on the upper side of the water tank 3;

[0037] The mounting plate 11 drives the heating lamp tubes 12 arranged at equal intervals to move back and forth vertically, which can improve the planting effect of rice seedlings in hydroponic culture. The "I"-shaped structure of the first connecting member 16 and the second connecting member 18 can prevent the belt 17 from falling off, thereby facilitating the adjustment of the height of the heating lamp tubes 12. The height adjustment structure is simple and reduces costs. The above electrical components are all existing technologies and will not be described in detail here.

[0038] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
