DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figures 1 to 5 , an intelligent water-saving irrigation device for seedling cultivation, comprising a placement plane 1, on which seedling trays 2 are evenly and equidistantly laid, and seedlings are laid on the seedling trays 2 for normal growth and development;

[0025] Two lead screws 5 are rotatably installed inside the placement plane 1, and the two lead screws 5 are both connected with lead screw nuts 10 through threads, and the two lead screw nuts 10 are fixedly installed with a moving frame 6;

[0026] By rotating the two lead screws 5 , the rotation of the lead screws 5 causes the lead screw nut 10 to move, and the movement of the lead screw nut 10 drives the moving frame 6 to move synchronously.

[0027] Two mounting blocks 18 are slidably mounted on the moving frame 6. A hollow tube 11 is rotatably mounted between the two mounting blocks 18, and nozzles 12 are evenly and equidistantly mounted on the hollow tube 11.

[0028] The height of the mounting block 18 can be adjusted, and thus the height of the nozzle 12 from the seedling tray 2 can also be adjusted. The optimal height of the nozzle 12 can be adjusted according to the size and growth conditions of the plants to achieve a water-saving effect.

[0029] Moreover, the hollow tube 11 can be rotated on the mounting block 18, so that the water spraying angle of the nozzle 12 can also be adjusted. When the angle between the nozzle 12 and the placement plane 1 is large, spraying activities can cover a wider range. When the angle between the nozzle 12 and the placement plane 1 is small, refined drip irrigation activities can be carried out. The most suitable and water-saving irrigation method can be selected according to actual needs.

[0030] Threaded rods 16 are rotatably installed at both ends of the hollow tube 11, and the two threaded rods 16 are connected by a conveyor belt 19. Nut pairs 17 are threadedly connected to the two threaded rods 16, and the nut pairs 17 are fixedly connected to the mounting blocks 18. One of the threaded rods 16 passes through the movable frame 6 and is fixedly installed with a handwheel 14.

[0031] By manually rotating the handwheel 14, one of the threaded rods 16 can be rotated, and the two threaded rods 16 can be rotated synchronously through the conveyor belt 19, and then the nut pair 17 drives the mounting block 18 to move vertically on the threaded rod 16, which can change the distance between the nozzle 12 and the seedling tray 2.

[0032] A motor 3 is arranged on the placement plane 1 , wherein one of the lead screws 5 passes through the placement plane 1 and is fixedly connected to the shaft output end of the motor 3 , and the two lead screws 5 are connected via a synchronous belt 4 .

[0033] When the motor 3 is started, one of the lead screws 5 will rotate, and the two lead screws 5 will rotate synchronously through the synchronous belt 4, so that the moving frame 6 moves on the placement plane 1 to irrigate the seedling trays 2 at different positions.

[0034] Two fixed rings 15 are fixedly installed on the hollow tube 11, and limiting grooves 23 are evenly and evenly provided in semicircular shapes on the two fixed rings 15. A moving block 13 is slidably installed on the moving frame 6, and a through groove 22 is provided on the moving block 13. The through groove 22 is adapted to the limiting groove 23, and a limiting rod 20 is movably installed on the through groove 22 and the two limiting grooves 23 in the same straight line.

[0035] When the limiting rod 20 is located on the through groove 22 and the limiting groove 23, the hollow tube 11 cannot rotate, so that the sprinkler head 12 can be stably maintained at a fixed angle for continuous watering activities.

[0036] When the limit rod 20 is taken out, that is, the limit rod 20 is not in the through groove 22 and the limit groove 23, the fixed ring 15 can be rotated, and then the hollow tube 11 can be rotated, and the angle of the nozzle 12 can be adjusted. When the nozzle 12 is adjusted to the required angle, the limit rod 20 is placed in the through groove 22 and the limit groove 23 which is in the same line as the through groove 22, so as to maintain the stability of the rotation angle of the nozzle 12.

[0037] A thread groove is formed at one end of the limiting rod 20 , and a nut 21 is threadedly connected to the end of the limiting rod 20 . The thread groove and the nut 21 prevent the limiting rod 20 from being easily separated from the through groove 22 and the limiting groove 23 .

[0038] A water tank 7 is fixedly installed at the bottom of the placement plane 1, and a water pump 8 is arranged on the water tank 7. The water tank 7 is connected to the water pump 8. A delivery pipe 9 is embedded in the output end of the water pump 8, and the other end of the delivery pipe 9 is fixedly installed on the hollow tube 11.

[0039] The water inside the water tank 7 is pumped out by the water pump 8, and then transported to the inside of the hollow tube 11 through the delivery pipe 9, and sprayed out through the nozzle 12 on the hollow tube 11, thereby performing irrigation activities. The delivery rate obtained by the water pump 8 can be adjusted according to actual needs.

[0040] The working process of the utility model is as follows: first, the height of the nozzle 12 is adjusted according to the growth condition of the plant, and the two threaded rods 16 are rotated synchronously by manually rotating the hand wheel 14 through the conveyor belt 19, and then the nut pair 17 drives the mounting block 18 to move vertically on the threaded rod 16, so that the distance between the nozzle 12 and the seedling tray 2 can be changed.

[0041] Then, according to actual needs, the rotation angle of the nozzle 12 is adjusted, and the limit rod 20 is taken out so that the fixed ring 15 can be rotated, and then the hollow tube 11 can be rotated, and the angle of the nozzle 12 can be adjusted. When the nozzle 12 is adjusted to the required angle, the limit rod 20 is placed into the through groove 22 and the limit groove 23 which is in the same line as the through groove 22, and the nut 21 is screwed on one end of the limit rod 20 to maintain the stability of the rotation angle of the nozzle 12.

[0042] After that, the motor 3 is started, and the two lead screws 5 rotate synchronously through the synchronous belt 4, and then the movable frame 6 moves on the placement plane 1. At this time, the water inside the water tank 7 is pumped out by the water pump 8, and then transported to the inside of the hollow tube 11 through the delivery pipe 9, and sprayed out through the nozzle 12 on the hollow tube 11 to irrigate the seedling trays 2 at different positions.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
