DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 5 As shown, in the present embodiment, an automatic watering Rehmannia planting device comprises a water tank 1, wherein the water tank 1 is placed at a high place, a water inlet pipe 2 is installed at the top of the water tank 1, a floating plate 3 is placed inside the water tank 1, a fixing rod 4 is fixedly installed in the middle of the floating plate 3, a winding wheel 5 is rotatably installed on the outer side of one end of the fixing rod 4 through a bearing, a pull rope 6 is wound around the middle of the winding wheel 5, one end of the pull rope 6 is fixedly installed in the middle of the winding wheel 5, a water outlet 7 is opened at the bottom of the water tank 1, a plugging cover 8 is installed at a position corresponding to the water outlet hole 7 in the water tank 1, one end of the pull rope 6 away from the winding wheel 5 is fixedly connected to the top of the plugging cover 8, a water outlet pipe 9 is installed at a position corresponding to the water outlet hole 7 at the bottom of the water tank 1, the water outlet pipe 9 is arranged in multiple sections, and a sprinkler head 10 is installed in the middle of the water outlet pipe 9.

[0023] like Figures 1 to 5 As shown, the inner wall of the water storage tank 1 is symmetrically fixedly installed with limit rods 11, a lifting block 12 is slidably installed between the two limit rods 11, and the two lifting blocks 12 are fixedly connected to the fixing rod 4.

[0024] The four limiting rods 11 are used to limit the lifting and lowering of the floating plate 3 .

[0025] like Figures 1 to 5 As shown, a spiral spring 13 is sleeved on the outer side of the end of the fixed rod 4 , the inner ring of the spiral spring 13 is fixedly connected to the fixed rod 4 , and the outer ring of the spiral spring 13 is fixedly connected to one side of the winding wheel 5 .

[0026] When the float plate 3 rises, the volute spring 13 slows down the time for the plugging cover 8 to cancel the blockage of the water outlet 7. After the water in the water storage tank 1 drops, the float plate 3 will drop. However, in this process, the pull rope 6 will be first stored inside the winding wheel 5 through the action of the volute spring 13. As the float plate 3 drops, the time for the plugging cover 8 to block the water outlet 7 is slowed down, thereby increasing the water output of the water storage tank 1.

[0027] like Figures 1 to 5As shown, positioning holes 14 are symmetrically opened on the outer side of the blocking cover 8 , and a positioning rod 15 is fixedly installed at the bottom of the inner wall of the water storage tank 1 at a position corresponding to the positioning hole 14 , and the positioning rod 15 is slidably connected to the positioning hole 14 .

[0028] It is used to limit the lifting and lowering of the blocking cover 8.

[0029] like Figures 1 to 5 As shown, an anti-slip ring 16 is fixedly installed on the top of the positioning rod 15.

[0030] Prevent the blocking cover 8 from sliding out of the top of the positioning rod 15.

[0031] like Figures 1 to 5 As shown, a connecting pipe 17 is fixedly installed at an equal distance in the middle of the water outlet pipe 9, a water storage box 18 is rotatably installed on the outer side of the bottom end of the connecting pipe 17 through a mechanical seal, the interior of the water storage box 18 is connected to the connecting pipe 17, a rotating rod 19 is rotatably installed on the inner wall of the connecting pipe 17, the bottom end of the rotating rod 19 is fixedly connected to the bottom of the water storage box 18, an impeller 20 is fixedly installed on the top of the rotating rod 19, a diversion pipe 21 is symmetrically fixedly installed on the outer side of the water storage box 18, the interior of the water storage box 18 is connected to the diversion pipe 21, and the bottom of the diversion pipe 21 is fixedly connected to the sprinkler head 10.

[0032] The water will enter the connecting pipe 17 through the water outlet pipe 9 and then enter the water storage box 18. At this time, the water will squeeze the impeller 20 and drive the impeller 20 to rotate. Then the water will enter the diversion pipe 21 and be sprayed out from the sprinkler head 10. At this time, the rotation of the impeller 20 will drive the diversion pipe 21 to rotate, so as to expand the area of ​​water spraying.

[0033] like Figures 1 to 5 As shown, a solenoid valve 22 is installed on the outer side of the water inlet pipe 2.

[0034] The water inlet speed inside the water storage tank 1 is adjusted to change the frequency of watering the Rehmannia glutinosa.

[0035] The utility model provides an automatic watering Rehmannia root planting device, and the specific working principle is as follows:

[0036] When the device is in use, the water inlet speed of the water inlet pipe 2 is adjusted by the solenoid valve 22, and the water inlet pipe 2 will flow into the water storage tank 1. After the water reaches a certain height, the buoyancy of the floating plate 3 will drive the pull rope 6 to pull the plug cover 8. Before that, in the process of the pull rope 6 pulling out the winding wheel 5, the spiral spring 13 will be deformed until the buoyancy of the floating plate 3 completely drives the plug cover 8 to cancel the blockage of the water outlet 7. The water will enter the connecting pipe 17 through the water outlet pipe 9 and then enter the water storage box 18. At this time, the water will squeeze the impeller 20 and drive the impeller 20 to rotate. The water will enter the diverter pipe 21 and be sprayed out from the sprinkler head 10. At this time, the rotation of the impeller 20 will drive the diverter pipe 21 to rotate, so as to expand the area of ​​water spraying. After the water in the water tank 1 drops, the float 3 will drop. However, in this process, through the action of the volute spring 13, the pull rope 6 will be first stored inside the winding wheel 5. As the float 3 drops, the water flow at the water outlet 7 will pull the plugging cover 8, and then drive the plugging cover 8 to block the water outlet 7. The water inlet pipe 2 will fill the water tank 1 with water, and this cycle will be repeated to achieve the next water irrigation.

[0037] 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.
