Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Such as Figures 1 to 4As shown in the figure, this embodiment includes a base 1. A groove 12 is formed inside the base 1. A main hollow gear 13 is installed at the center of the groove 12. A support base 2 is arranged above the main hollow gear 13. The lower end of the support base 2 does not contact the main hollow gear 13. A fixed sleeve 15 is installed at the upper end of the support base 2. A lifting pipe 8 is slidably connected inside the fixed sleeve 15. A circular channel is arranged inside the support base 2 and is communicated with the fixed sleeve 15. The lifting pipe 8 has a certain length and can slide inside the fixed sleeve 15 and the support base 2. A bellows 17 is installed at the lower end of the lifting pipe 8. The bellows 17 penetrates through the support base 2 and the base 1 and is connected to the underground water pipe. After the underground water enters the inside of the bellows 17, it then enters the inside of the lifting pipe 8. It should be noted that most of the bellows 17 is located in the channel inside the support base 2, which can prevent the bellows 17 from shaking in other directions during the water supply process. A lifting head 10 is installed at the upper end of the lifting pipe 8. Four atomizing nozzles 11 are arrayedly installed on the surface of the lifting head 10. The four atomizing nozzles 11 can spray the underground water outward to irrigate the vegetables. Four sub-gears 14 are meshed and connected to the surface of the main hollow gear 13. The upper ends of the sub-gears 14 are installed with threaded rods 3 through rotating shafts. The upper ends of the threaded rods 3 are threadedly connected to lifting sleeves 4. A connecting plate 6 is installed at the upper end of the lifting sleeve 4. A protective cover 5 is jointly installed among the four connecting plates 6. The protective cover 5 is located above the lifting head 10. By rotating the main hollow gear 13, the four sub-gears 14 are driven to rotate. The sub-gears 14 drive the rotating shafts and the threaded rods 3 to rotate. The lifting sleeves 4 on the surface of the threaded rods 3 will move up and down along the length direction of the threaded rods 3 as the threaded rods 3 rotate. The four lifting sleeves 4 drive the four connecting plates 6 and the protective cover 5 to move up and down synchronously. By lowering the height of the protective cover 5, the lifting head 10 is covered by the protective cover 5, avoiding excessive contact between the lifting head 10, the atomizing nozzles 11 and the external environment, and reducing the probability of damage to the atomizing nozzles 11.

[0022] Specifically, a sealing plate 7 is installed at the opening of the groove 12. Four through holes are formed on the surface of the sealing plate 7. The sizes of the four through holes are adapted to the sizes of the rotating shafts. It should be noted that a rotating shaft is first arranged at the upper end of the sub-gear 14. The rotating shaft passes through the through hole and extends above the sealing plate 7. A threaded rod 3 is installed at the upper end of the rotating shaft. A sealing gasket needs to be arranged at the connection between the rotating shaft and the through hole to enhance the sealing performance and prevent the sprayed water from entering the inside of the groove 12.

[0023] Furthermore, a lifting structure 9 is commonly installed between the lifting pipe 8 and the four lifting sleeves 4. The lifting structure 9 includes a lifting ring 901, a connecting rod 902, and a fixing ring 903. A fixing ring 903 is installed on the surface of each of the four lifting sleeves 4. A lifting ring 901 is slidably sleeved on the surface of the lifting pipe 8. The lifting ring 901 and the four fixing rings 903 are connected by a connecting rod 902 respectively. The size of the lifting ring 901 is smaller than that of the lifting head 10. Through the lifting movement of the four lifting sleeves 4, the four fixing rings 903 will be driven to move up and down synchronously. The four fixing rings 903 drive the four connecting rods 902 and the lifting ring 901 to move up and down synchronously. When the upper end of the lifting ring 901 contacts the lower end of the lifting head 10, the lifting head 10 and the lifting pipe 8 will be driven to move up and down synchronously inside the fixed sleeve 15, thereby changing the height of the four atomizing nozzles 11 to meet the irrigation requirements at different heights. It should be noted that there is a certain distance between the lifting structure 9 and the protective cover 5, and this distance is greater than the total height of the lifting head 10, so that when the lifting structure 9 contacts the lifting head 10, the protective cover 5 must be located above the lifting head 10 at this time, and it will not affect the use of the atomizing nozzles 11.

[0024] Furthermore, a driving gear 16 is meshed and connected to a position on the surface of the main hollow gear 13 that is not adjacent to the secondary gear 14. A driving motor is installed at the lower end of the driving gear 16 inside the base 1. The driving motor is a common servo motor on the market and is connected to an external power supply. The driving motor drives the driving gear 16 to rotate, the driving gear 16 drives the main hollow gear 13 to rotate, and the main hollow gear 13 drives the four secondary gears 14 to rotate. It should be noted that the secondary gear 14 is rotatably connected to the groove 12, and the position of the secondary gear 14 cannot be changed.

[0025] Furthermore, the four atomizing nozzles 11 and the four lifting sleeves 4 are arranged in an alternating manner. The four corners at the lower end of the support base 2 are connected to the surface of the groove 12 through support columns. The support base 2 and the groove 12 are connected by the four support columns. The main hollow gear 13 is located between the support base 2 and the groove 12. The four atomizing nozzles 11 and the four lifting sleeves 4 are arranged in an alternating manner, which can avoid the situation that the lifting sleeve 4 blocks the atomizing nozzle 11.

[0026] The usage method of this embodiment is as follows: By rotating the main hollow gear 13, the four secondary gears 14 are driven to rotate. The secondary gears 14 drive the rotating shaft and the threaded rod 3 to rotate. The lifting sleeve 4 on the surface of the threaded rod 3 will move up and down along the length direction of the threaded rod 3 as the threaded rod 3 rotates. The four lifting sleeves 4 drive the four connecting plates 6 and the protective cover 5 to move up and down synchronously. Groundwater enters the inside of the lifting pipe 8 and the lifting head 10 through the corrugated pipe 17, and finally is sprayed out through the four atomizing nozzles 11 to irrigate the vegetables. After irrigation, by lowering the height of the protective cover 5, the lifting head 10 is covered by the protective cover 5, so as to avoid excessive contact between the lifting head 10 and the atomizing nozzles 11 and the external environment, and reduce the probability of damage to the atomizing nozzles 11.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
