Description

Technical Field

[0001] This utility model relates to an adjustable flow drip irrigation device, belonging to the technical field of drip irrigation devices. Background Technology

[0002] To conserve water resources, sprinkler or drip irrigation is generally used in fruit and vegetable cultivation. Drip irrigation, in particular, can greatly save irrigation water for fruit and vegetable cultivation due to its continuous, quantitative, and targeted nature.

[0003] Existing drip irrigation devices simply involve drilling holes in a flexible tube for drip irrigation. This method makes it difficult to align the tubes precisely with the fruits and vegetables. This is because after each use, when the tube is recycled and reused to irrigate a new batch of fruits and vegetables, there will be misalignment issues. Furthermore, flexible tube drip irrigation cannot be used for in-soil drip irrigation, making it less adaptable. To address these shortcomings, this invention proposes a drip irrigation device with adjustable flow rate. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable flow drip irrigation device, the structure of which includes an irrigation pipe, a plurality of drip irrigation devices are connected at intervals on the irrigation pipe, each drip irrigation device includes an adjusting valve body, the outlet end of the adjusting valve body is connected to a diverter connector, and the inlet end of the adjusting valve body is connected to a first connecting hose for communicating with the irrigation pipe, and the other end of the diverter connector is connected to a drip irrigation plug through a plurality of second connecting hoses;

[0006] Each of the drip irrigation plugs includes a plug, and the top surface of the plug is sealed and locked with a rod by a sealing ring. The top surface of the rod is connected to a pipe connector, and the plug, rod, and pipe connector are interconnected.

[0007] A further improvement is that the plug is integrally formed by the plug body, the abutment and the external thread locking edge, the top surface of the plug has a through groove in the middle, and the left side of the through groove has a first drip irrigation hole, and the lower end of the plug body has a tapered surface.

[0008] A further improvement is that a channel is provided through the middle of the top surface of the insertion rod, and an internal thread is provided at the upper end of the channel to connect with the pipe joint thread. A second drip irrigation hole is provided on the left side of the channel, and an internal thread locking groove is provided on the periphery of the bottom surface of the insertion rod to connect with the external thread locking edge.

[0009] A further improvement is that the plug, insert, and pipe fitting are all made of plastic.

[0010] A further improvement is that the vertical tilt angle of the insertion rod on the top surface of the plug is 20-30º.

[0011] Further improvements are made to the fact that the irrigation pipe, regulating valve body, and diversion joint are all existing technologies, and their structures will not be described in detail here.

[0012] The beneficial effects of the utility model are:

[0013] This utility model provides an adjustable flow drip irrigation device. The device consists of a regulating valve body, a diverter, a first connecting hose, a second connecting hose, and drip irrigation plugs, which are then quickly connected to an irrigation pipe to form an adjustable flow drip irrigation device. This device uses multiple drip irrigation plugs that extend freely and are precisely aligned and inserted into the sides of fruit and vegetable plants. The regulating valve body adjusts the flow rate of each drip irrigation plug accordingly, enabling precise drip irrigation of the plant body and the soil around its roots. This drip irrigation device can be used repeatedly and is highly practical. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1-4 The present invention discloses a schematic diagram of an adjustable flow drip irrigation device: its structure includes an irrigation pipe 1, on which multiple drip irrigation devices 2 are connected at intervals. Each drip irrigation device 2 includes a regulating valve body 3, and the outlet end of the regulating valve body 3 is connected to a diverter 4. The inlet end of the regulating valve body 3 is connected to a first connecting hose 5 for communicating with the irrigation pipe 1. The other end of the diverter 4 is connected to a drip irrigation plug 7 through multiple second connecting hoses 6. Each drip irrigation plug 7 includes a plug 71, and the top surface of the plug 71 is sealed and inclinedly locked with a rod 72 by a sealing ring 74. The top surface of the rod 72 is connected to a pipe connector 73. The plug 71, the rod 72, and the pipe connector 73 are interconnected.

[0020] The plug component 71 is integrally formed by the plug body 711, the abutment edge 712 and the external thread locking edge 713. A through groove 714 is provided in the middle of the top surface of the plug component 71, and a first drip irrigation hole 715 is provided on the left side of the through groove 714. A tapered surface 716 is provided at the lower end of the plug body 711.

[0021] The top surface of the insertion rod 72 has a through channel 721, and the upper end of the channel 721 has an internal thread 722 that is threaded to the pipe connector 73. The left side of the channel 721 has a second drip hole 723. The bottom surface of the insertion rod 72 has an internal thread locking groove 724 that is threaded to the external thread locking edge 713.

[0022] The plug 71, the insert 72, and the pipe connector 73 are all made of plastic.

[0023] The vertical tilt angle of the insertion rod 72 to the top surface of the plug 71 is 20-30º.

[0024] Working principle:

[0025] In use, water is quickly connected to the irrigation pipe 1 via the first connecting hose 5. The drip irrigation device 2 is pre-assembled at this time. Then, the drip irrigation plug 7 is inserted into the soil on the side of the fruit and vegetable plant, with the plug 71 deeply embedded in the soil. The second drip irrigation hole 723 on the plug 72 is tilted above the fruit and vegetable plant. The flow rate of a single drip irrigation device 2 is adjusted by the regulating valve body 3, so that water enters the channel 714 and the passage 721 through the first connecting hose 5, the regulating valve body 3, the second connecting hose 6, and the pipe connector 73. Water flows out from the second drip irrigation hole 723 and drips into the soil at the root of the fruit and vegetable plant, respectively.

[0026] Because each drip irrigation plug 7 of the drip irrigation device 2 can freely extend and move, it can be accurately positioned for repeated use on fruit and vegetable plants.
