Description

Technical Field

[0001] This utility model relates to a greenhouse sprinkler irrigation structure and belongs to the field of greenhouse planting technology. Background Technology

[0002] Sprinkler irrigation is an important agricultural irrigation technology that delivers water evenly to plants inside the greenhouse through spraying to meet the needs of crop growth. The sprinkler system can precisely irrigate according to the crop's water requirements, avoiding water waste and improving water resource utilization efficiency. It can ensure that every corner of the greenhouse receives adequate water, promoting balanced crop growth. It can also be automated, reducing the labor intensity of manual irrigation and improving production efficiency. Furthermore, it can increase air humidity and regulate temperature inside the greenhouse, providing a better growing environment for crops.

[0003] Most greenhouse sprinkler irrigation systems use pipes installed on the frame at the top of the greenhouse, with multiple nozzles for targeted irrigation. However, it is difficult to ensure uniform spraying and it can affect the overall structure of the greenhouse, increasing initial investment costs. Furthermore, when irrigating different crops in the greenhouse, the high position of the sprinkler makes it difficult to operate and target specific crops, reducing the effectiveness of the irrigation. It is also difficult to adjust the number of sprinklers. Utility Model Content

[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0030] like Figure 1-6 As shown, the greenhouse sprinkler irrigation structure includes:

[0031] Track 1, with a horizontal plate 5 at the bottom of the track 1, a walking mechanism fixedly installed on the surface of the horizontal plate 5, and fixed frames 7 fixedly installed at both ends of the horizontal plate 5, with the walking mechanism located inside the fixed frames 7. The fixed frames 7 and the horizontal plate 5 are both inserted through the lifting mechanism.

[0032] The fixed block 15 is fixedly connected to the lifting mechanism and fixedly connected to both ends of the spray pipe 22. The bottom of the spray pipe 22 is provided with a number of evenly distributed nozzles 23. The surface of the nozzles 23 is rotatably connected to an adjustment mechanism, and the adjustment mechanism is connected to a transmission mechanism installed on the fixed block 15.

[0033] There are two tracks 1, which are symmetrically distributed on both sides of the greenhouse. Each track 1 is fixedly connected to a pole 2 at both ends. The side walls of the pole 2 are fixedly connected to hooks 3 by inclined reinforcing rods 4, and the hooks 3 are fixedly connected to both ends of the track 1.

[0034] Both ends of the horizontal plate 5 are fixedly connected to the limiting plate 6, and the limiting plate 6 is correspondingly arranged below the track 1 and is attached to the bottom surface of the track 1.

[0035] In this technical solution, after the track 1 is installed, the horizontal plate 5 can move at the bottom of the track 1, and the track 1 is installed on both sides of the greenhouse by the uprights 2. The stability is improved by the reinforcing rod 4, and the hooks 3 are used to fix it to the top frame of the greenhouse, so as to achieve stable installation of the uprights 2 and the track 1.

[0036] There are two fixing frames 7, which are symmetrically distributed on both sides of the horizontal plate 5 and located between the two tracks 1. Each fixing frame 7 has a U-shaped cross-section, and each fixing frame 7 has two symmetrically distributed supports 8 fixedly connected inside.

[0037] The walking mechanism includes a dual-axis motor 11, which is fixedly installed at the top center of the horizontal plate 5. The output end of the dual-axis motor 11 is fixedly connected to the transmission shaft 10. A walking wheel 12 is fixedly installed at the end of the transmission shaft 10, and the walking wheel 12 is located inside the track 1.

[0038] In this technical solution, the cooperation between the fixing frame 7 and the bracket 8 enables the installation of the bearing 9, allowing the drive shaft 10 to rotate inside the bearing 9, thereby driving the traveling wheel 12 to rotate stably. During irrigation, the dual-axis motor 11 is started, causing it to drive the drive shaft 10 to rotate, which in turn drives the traveling wheel 12 to rotate on the surface of the track 1. The traveling wheel 12 drives the horizontal plate 5 to move, and the limiting plates 6 on both sides of the horizontal plate 5 move below the track 1, achieving stable movement of the horizontal plate 5.

[0039] The bracket 8 has an L-shaped cross-section. A bearing 9 is fixedly installed on the side wall of the bracket 8, and a transmission shaft 10 is rotatably connected inside the bearing 9. The bearing 9 can realize the stable rotation of the transmission shaft 10. The bracket 8 can be used to install the bearing 9 and at the same time limit the gear shaft 14.

[0040] The lifting mechanism includes a long screw 13, which is inserted through the inside of the fixed frame 7 and the support 8. A gear shaft 14 is threaded onto the surface of the long screw 13. The gear shaft 14 is located between the horizontal plate 5 and the support 8. A first motor 16 is fixedly installed at the bottom of the horizontal plate 5. The output end of the first motor 16 is fixedly connected to the output gear 17, and both sides of the output gear 17 are meshed with the gear shaft 14.

[0041] In this technical solution, when adjusting the height of the spray pipe 22, the first motor 16 is started, which drives the output gear 17 to rotate. When the output gear 17 drives the gear shaft 14 to rotate, the gear shaft 14 rotates between the horizontal plate 5 and the bracket 8. Because the gear shaft 14 is restricted, when the gear shaft 14 rotates, it drives the long screw 13 to move, thereby driving the fixed block 15 and the spray pipe 22 to adjust their height.

[0042] The top of both ends of the fixing block 15 are fixedly connected to the long screws 13, and the spiral directions of the two long screws 13 are opposite. A transmission mechanism is fixedly installed on the top of the fixing block 15. The transmission mechanism includes a second motor 18, which is fixedly connected to the top of the fixing block 15. The inside of the fixing block 15 is rotatably connected to the worm gear 19. The output end of the second motor 18 and the worm gear 19 are both fixedly connected to the pulleys 20, and the pulleys 20 are connected to each other by a belt 21.

[0043] The adjustment mechanism includes a sleeve 25, which is rotatably connected to the surface of the nozzle 23. Fine holes 24 are provided on both sides of the surface of the nozzle 23. A baffle 27 is fixedly connected to the bottom of the sleeve 25. The baffle 27 is attached to the bottom surface of the nozzle 23 and is distributed correspondingly to the fine holes 24.

[0044] The top of the sleeve 25 is fixedly connected to a worm gear 26 with an annular structure, and the worm gear 26 is meshed with the worm 19. The worm 19 is correspondingly arranged on one side of the spray pipe 22. The spray pipe 22 is connected to the water pump 28 through the hose 29, and the water pump 28 is fixedly installed on the top of the horizontal plate 5.

[0045] In this technical solution, the second motor 18 is started, and the worm gear 19 is rotated through the cooperation of the belt 21 and the pulley 20. When the worm gear 19 drives the worm wheel 26 to rotate, the worm wheel 26 drives the sleeve 25 to rotate on the surface of the nozzle 23. When the sleeve 25 rotates, it drives the baffle 27 to move to the vicinity of the fine hole 24, thereby blocking the fine hole 24. The spray quantity is adjusted by adjusting the rotation angle of the sleeve 25, and the water mist spray range is kept constant by changing the water pressure to ensure uniform irrigation.
