However, in actual farmland operation, especially when soil ploughing is carried out by using machine, splashing soil particles and various impurities will inevitably be produced. These splashes are easy to directly impact and adhere on the dripper or drip pipe hole of drip irrigation pipe due to their momentum and the viscosity of wet soil. Considering that the aperture of drip pipe hole is designed relatively small to ensure accurate water flow control, this design also means that they are particularly sensitive to blockage. Once the drip pipe hole is blocked by soil, impurities and the like, not only irrigation efficiency will be affected, but also water resource waste and crop growth limitation can be caused. More troublesome is that due to the small size of drip pipe hole, manual cleaning is not only time-consuming and laborious, but also has limited effect.

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] like Figures 1-3 As shown, a clog-resistant drip irrigation head for planting includes a drip irrigation body 1, which is fixedly installed on an irrigation pipe 11. The irrigation pipe 11 is externally connected to a pressurizing device, which is existing technology and can be a commonly used pressurizing pump.

[0021] Specifically, the drip irrigation body 1 has a hollow shell structure, with an opening 12 at the top for communicating with the irrigation pipe 11, and a channel opening 13 at the bottom; the outer wall of the top of the drip irrigation body 1 has an external thread 14, which can be a thread directly integrally formed on the drip irrigation body 1, or a thread embedded in a standard metal part on the drip irrigation body 1 during production; the irrigation pipe 11 is a pipe set in sections, and the pipe sections are connected by an internal thread tee, and the drip irrigation body 1 can be threadedly connected to the internal thread tee.

[0022] Furthermore, a regular hexagonal frustum 15 is provided on the outer wall of the middle part of the drip irrigation body 1. The drip irrigation body 1 can be disassembled and assembled by turning the regular hexagonal frustum 15 with a wrench. When the regular hexagonal frustum 15 is installed, one end face will abut against the end face of the opening of the internal thread tee.

[0023] Furthermore, the drip irrigation body 1 is provided with a drip irrigation part 16 at the end away from the irrigation pipe 11. The drip irrigation part 16 is an arc-shaped cover structure, and an arc surface 17 is formed on its outer wall by an arc chamfer 25. A channel opening 13 is opened in the center of its bottom.

[0024] Furthermore, an installation rod 2 is inserted through the channel opening 13, and a gap is provided between the installation rod 2 and the channel opening 13.

[0025] Furthermore, one end of the mounting rod 2 extends out of the channel opening 13, and a baffle 21 is integrally fixed to this end. The baffle 21 has an arc-shaped structure, and the curvature of its arc is towards the channel opening. The baffle 21 covers the channel opening 13 and has multiple blocking holes 22. The end face of the blocking hole 22 is tangent to the arc surface of the baffle 21, that is, the blocking holes 22 are oriented outward from the center of the arc-shaped baffle 21.

[0026] Furthermore, the baffle 21 is a rigid baffle 21, the outer wall of the drip irrigation part 16 and the inner wall of the baffle 21 abut against each other, the outer edge of the inner wall of the baffle 21 presses against the arc surface 17 of the drip irrigation part 16, and the outer wall of the drip irrigation part 16 and the inner wall of the baffle 21 surround and form a closed area.

[0027] Furthermore, one end of the mounting rod 2 is inserted into the drip irrigation body 1, and a mounting plate 23 is fixedly connected to that end. The mounting plate 23 is made of hard rubber, and the mounting rod 2 and the mounting plate 23 are interference-fitted or threaded. The mounting plate 23 and the inner wall of the drip irrigation body 1 are slidably connected, and the mounting plate 23 can move relative to the inner wall of the drip irrigation body 1. An overflow hole 24 is provided on the mounting plate 23. The overflow hole 24 has a tapered hole structure with a gradually decreasing diameter in the direction of the mounting plate 23 pointing towards the mounting rod 2, so as to form a gap space for liquid to pass through to the channel opening 13.

[0028] Furthermore, the mounting plate 23 has a rounded chamfer 25 at one end edge away from the mounting rod 2.

[0029] Furthermore, a spring 26 is provided between the mounting plate 23 and the drip irrigation part 16, with the two ends of the spring 26 abutting against the inner walls of the mounting plate 23 and the drip irrigation part 16, respectively.

[0030] Furthermore, the drip irrigation body 1 has a flow-through area 3 located in the region of the regular hexagonal frustum 15. The inner wall of the drip irrigation body 1 in the flow-through area 3 has multiple gap grooves 31. The gap grooves 31 are arc-shaped grooves evenly spaced along the inner wall of the drip irrigation body 1. When the mounting plate 23 moves to the flow-through area 3, a flow-through gap for liquid to pass through is always formed between the mounting plate 23 and the drip irrigation body 1.

[0031] Furthermore, a stop 4 is provided on the side wall of the mounting rod 2. The stop 4 is a protrusion fixed to the mounting rod 2. When the mounting rod 2 moves to a certain position in the flow area 3, the protrusion will interfere with the side edge of the channel opening 13, preventing the mounting rod 2 from continuing to move. At this time, the mounting plate 23 is located in the height area between the upper and lower groove walls of the gap groove 31.

[0032] The specific implementation process of this utility model is as follows: When drip irrigation is performed, the pressure pump does not work, and the drip irrigation water is discharged from the channel opening 13 through the overflow hole 24 to achieve drip irrigation; when sprinkler irrigation is performed, the pressure pump works, and the water pressure squeezes the mounting plate 23. The mounting plate 23 resists the pressure of the spring 26 and is pressed down to a certain position. The stop 4 and the side edge of the channel opening 13 abut against each other, opening the flow gap. The water flows through the flow gap and sprays out from the channel opening 13; during this process, the mounting rod 2 drives the baffle 21 to move away from the channel opening 13. The sprayed water flows through the baffle 21 and is guided and dispersed for spraying. At the same time, the baffle 21 is rinsed to clean the mud and sand on it.

[0033] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
