Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, specifically an energy-saving sprinkler irrigation device for greenhouse seedling cultivation. Background Technology

[0002] In greenhouse seedling production, scientific irrigation is key to ensuring uniform seedling growth and improving survival rate. Currently, fixed pipeline sprinkler irrigation systems are commonly used in greenhouses. The sprinkler heads of this type of system are usually fixedly installed on the pipeline at preset intervals to form a fixed spraying pattern.

[0003] However, different types of seedlings require different planting spacings, and even the same type of seedlings require different canopy space at different growth stages. Fixed-spacing sprinklers cannot be flexibly adjusted according to these changes, resulting in a mismatch between the spraying range and the seedbed layout. If the spacing is too large, irrigation blind spots will appear, affecting seedling growth. If the spacing is too small, water resources will be sprayed in an overlapping manner and wasted.

[0004] Secondly, a fixed spraying height makes it difficult to achieve precise delivery. The vertical distance between the nozzle and the seedbed directly affects the coverage area and impact force of the water flow. A fixed spraying height cannot simultaneously meet the different needs of the seedling stage and the growth stage. If the height is too high, the water droplets will easily scatter and the evaporation loss will be large. Moreover, the atomized water droplets may increase the humidity in the greenhouse and aggravate the risk of disease. If the height is too low, the coverage area will be limited, and the impact of the water flow may damage the soil structure or damage the delicate seedlings. Utility Model Content

[0007] Furthermore, the fixed cylinder has two mounting holes on its exterior, and the telescopic rod has several equidistant positioning holes.

[0008] Furthermore, a bolt is provided between the two mounting holes and the two positioning holes, and a nut is threaded onto one end of the bolt.

[0009] Furthermore, connecting rods are fixedly connected between the opposite sides of the fixed cylinder and the bottom of the frame, and reinforcing ropes are fixedly installed on the opposite sides of the frame, with the bottom ends of the two reinforcing ropes connected to the two limiting rings respectively.

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] As attached Figures 1 to 5 The energy-saving sprinkler irrigation device for greenhouse seedling cultivation shown includes: a frame 1, two fixed cylinders 11 fixedly installed at the bottom of the frame 1, telescopic rods 12 slidably connected inside the fixed cylinders 11, an installation rod 13 fixedly connected between the bottom ends of the telescopic rods 12, two limiting rings 14 threadedly connected to opposite ends of the installation rod 13, a number of nozzles 15 provided below the installation rod 13, and pipe clamps 16 fixedly installed at the top of each nozzle 15, with the pipe clamps 16 installed outside the installation rod 13.

[0025] Specifically: When irrigating seedlings in the greenhouse, the distance between several nozzles 15 is adjusted according to the planting spacing. First, the pipe clamp 16 is loosened to release the fixing of the installation rod 13. Then, the nozzles 15 are moved to adjust the spacing. After the adjustment is completed, the pipe clamp 16 is tightened to fix the nozzles 15. The water pipe for delivery is connected to the interface of several nozzles 15 respectively. By pulling the telescopic rod 12 out of the fixed cylinder 11, the distance between the installation rod 13 and the seedling can be adjusted, thereby ensuring that the sprayed water can fall accurately into the seedling soil and minimizing the waste of irrigation water.

[0026] In a preferred embodiment, the fixed cylinder 11 has two mounting holes 2 on its exterior, and the telescopic rod 12 has several equidistantly distributed positioning holes 21. A bolt 22 is provided between the two mounting holes 2 and the two positioning holes 21, and a nut 23 is threaded to one end of the bolt 22.

[0027] Furthermore, after adjusting the length of the telescopic rod 12, ensure that the positioning hole 21 is aligned with the two mounting holes 2, and then insert the bolt 22 into the positioning hole 21 and the mounting hole 2 to fix the length of the telescopic rod 12. Then screw the nut 23 onto the bolt 22 to fix the bolt 22 in place and prevent the bolt 22 from moving out of the positioning hole 21 and the mounting hole 2.

[0028] In a preferred embodiment, connecting rods 24 are fixedly connected between the two opposite sides of the fixed cylinder 11 and the bottom of the frame 1, and reinforcing ropes 25 are fixedly installed on the two opposite sides of the frame 1, with the bottom ends of the two reinforcing ropes 25 connected to the two limiting rings 14 respectively.

[0029] Furthermore, the stability of the fixing cylinder 11 is enhanced by the connecting rod 24 to prevent the fixing cylinder 11 from loosening after long-term use, and the stability of the mounting rod 13 is enhanced by the reinforcing rope 25 to keep the mounting rod 13 balanced.

[0030] In a preferred embodiment, a plurality of rotating rods 3 are rotatably connected to the frame 1. Rollers 31 are fixedly installed at opposite ends of the rotating rods 3. Guide rails 32 are provided on opposite sides of the frame 1. The rollers 31 on both sides are located inside the two guide rails 32. A drive motor 4 is fixedly installed in the frame 1. A drive bevel gear 41 is fixedly installed at the top of the drive shaft of the drive motor 4. A driven bevel gear 42 is fixedly installed on one of the rotating rods 3. The drive bevel gear 41 and the driven bevel gear 42 are meshed and connected. A protective cover 43 is fixedly installed on the top of the frame 1.

[0031] Furthermore, when spraying, the drive motor 4 is started, and the drive motor 4 drives the active bevel gear 41 to rotate. The active bevel gear 41 rotates and meshes with the driven bevel gear 42, which in turn drives the connected rotating rod 3 to rotate. The rotating rod 3 drives the rollers 31 at both ends to rotate. The rollers 31 rotate and move along the inside of the two guide rails 32, thereby driving the frame 1 to move forward. The two guide rails 32 are mounted on the frame at both ends of the greenhouse. Multiple pairs of rollers 31 can keep the frame 1 stable.

[0032] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
