Description

Technical Field

[0001] This utility model relates to the field of tomato cultivation technology, specifically to a drip irrigation flow control device for tomato cultivation. Background Technology

[0002] Drip irrigation tape uses plastic tubing (drip irrigation pipe) to deliver water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10mm for localized irrigation. It delivers water drop by drop, evenly and slowly, to the soil near the roots of the crop through drippers or drip tape with very small outflow orifices. It is commonly used in tomato cultivation.

[0003] Chinese patent application number 202210626265.7 discloses a drip irrigation device suitable for tomato cultivation, including a water supply tank and multiple sets of concave frames. Each set of concave frames has a drip irrigation pipe at its bottom, and multiple sets of water outlet holes are formed on one side wall of each drip irrigation pipe. A mixing box is fixedly connected to the top center of each concave frame. The mixing box is connected to both the water supply tank and the drip irrigation pipes. A drive box is fixedly connected to the top of the mixing box. A rotating rod is rotatably connected inside the drive box. An impeller is fixedly connected to the upper end of the rotating rod. The component extends through the drive box and mixing chamber into the concave frame. Multiple sets of stirring rods are installed on the outer wall of one end of the rotating rod inside the mixing chamber. The mixing chamber is connected to the drip irrigation pipe. A water pump is fixedly connected to the outer wall of one side of the water supply tank. The water pump's input end is connected to the water supply tank, and its output end is connected to the drive box. The rotating rod drives the stirring rods to rotate inside the mixing chamber, stirring the water and fertilizer flowing from the water supply tank into the mixing chamber. This avoids the problem of sediment in the water and fertilizer failing to flow out due to the slow flow rate of the drip irrigation, thus improving the effectiveness of water and fertilizer application.

[0004] The drip irrigation device used for tomato cultivation is inconvenient to control the drip volume of different zones during zonal irrigation, and the cost of installing solenoid valves separately is high. Therefore, we propose a drip irrigation flow control device for tomato cultivation. Utility Model Content

An outer protective filter sleeve 22 is fixedly connected to the bottom of the second ring block 21. The outer protective filter sleeve 22 is sleeved on the outside of the drip irrigation pipe 18. Inside the mixing tank 1, a rotating roller 3 is rotatably connected via bearings. Multiple stirring blades 4 are fixedly connected to the outside of the rotating roller 3 and inside the mixing tank 1. An electromechanical box is fixedly installed on the top of the mixing tank 1. A servo motor 5 is fixedly installed inside the electromechanical box. The output end of the servo motor 5 is fixedly connected to the rotating roller 3 via a coupling. The servo motor 5 can drive the rotating roller 3 and the stirring blades 4 to rotate, thereby stirring the water and fertilizer inside the mixing tank 1 to dissolve the fertilizer in the water, thus facilitating irrigation. A first control valve 9 is provided at the connection between the water distribution pipe 8 and the first water supply pipe 6. A second control valve 12 is provided on the outside of the connecting pipe 11. The first control valve 9 facilitates the injection of water into the metering bag 10, and the second control valve 12 facilitates the control of the flow rate inside the connecting pipe 11, thereby controlling the dripping speed of the drip irrigation pipe 18. The outer side of the metering bag 10 is provided with a scale strip 13, which facilitates the measurement of the amount of water and fertilizer injected into the metering bag 10. An annular locking block 14 is sleeved on the outside of the water distribution pipe 8. A connecting rod 15 is fixedly connected to the bottom of the annular locking block 14. A fixed base plate 16 is fixedly connected to the bottom of the connecting rod 15.
