Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation equipment technology, and in particular relates to a drip nozzle for planting. Background Technology

[0002] In traditional agricultural irrigation practices, sprinkler irrigation and drip irrigation constitute the two main irrigation methods. Sprinkler irrigation, with its wide coverage area, can quickly replenish farmland with water in a short time; however, its water use efficiency is relatively low, with some water lost through evaporation or surface runoff. In contrast, drip irrigation technology, by precisely controlling water flow, delivers water directly to plant roots, effectively reducing water evaporation and waste, and significantly improving water use efficiency. Unfortunately, most irrigation equipment currently on the market only provides single sprinkler or drip irrigation functions, lacking comprehensive solutions that combine the advantages of both. Furthermore, in actual farmland operations, especially when using machinery for soil tillage, splashing soil particles and various impurities are inevitably generated. Due to their momentum and the inherent stickiness of wet soil, these splashes easily impact and adhere to the drippers or drip tube orifices, causing blockages and affecting irrigation efficiency and crop growth. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a drip nozzle for planting that integrates both spray and drip irrigation modes, effectively solves the clogging problem in the drip irrigation mode, and improves irrigation efficiency and water resource utilization.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a drip irrigation head for planting, comprising a drip irrigation body, wherein the drip irrigation body is installed on an irrigation pipe, and a pressurizing device is connected to the outside of the irrigation pipe; the drip irrigation body is a hollow structure, with an opening at one end for communicating with the irrigation pipe, and a channel opening at the other end; an installation plate is movably installed inside the drip irrigation body, the installation plate being slidably fitted inside the drip irrigation body and disposed without gap with the inner wall of the drip irrigation body, and is movable relative to the drip irrigation body; a drip tube is fixedly inserted through the installation plate, one end of the drip tube being fitted into the channel opening, and the liquid flow from the irrigation pipe flows to the outside through the drip tube; the drip irrigation body has a flow-through area, and when the installation plate moves into the flow-through area, the installation... A gap is formed between the plate and the inner wall of the drip irrigation body, increasing the flow area in that area. Spray holes are provided at the bottom of the drip irrigation body, angled downwards away from the body, and evenly distributed around its circumference. A reset element is provided on the mounting plate to limit its initial position. Through the internal structure and pressurization device of the drip irrigation body, the flow rate of liquid can be limited even with limited hydraulic pressure, allowing liquid to exit only from the drip tubes, thus creating a drip irrigation effect. When the hydraulic pressure reaches a certain threshold, the mounting plate is squeezed and moved. When the mounting plate moves to the flow area, the flow rate increases, and the liquid is guided by the spray holes to create a dispersed spray effect, achieving both sprinkler and drip irrigation modes, thus improving irrigation efficiency and water resource utilization.

[0005] Preferably, the reset element is a spring, with one end abutting against the mounting plate and the other end abutting against the bottom of the inner wall of the drip irrigation body; this is used to limit the movement of the mounting plate while ensuring the working reset of the mounting plate.

[0006] Preferably, a gap groove is formed on the inner wall of the drip irrigation body. The gap groove is located in the flow area. When the mounting plate moves into the flow area, a flow gap for liquid to pass through is always formed between the mounting plate and the drip irrigation body.

[0007] Preferably, a stop frame is provided in the flow area. When the mounting plate moves to a certain position, the mounting plate and the stop frame interfere with each other, and at this time the flow gap opens; so as to ensure the opening of the flow gap and ensure the normal operation of sprinkler irrigation.

[0008] Preferably, the stop frame is provided with a guide sleeve, and the drip tube is fitted inside the guide sleeve to further guide the movement of the drip tube, so as to ensure the normal movement of the mounting plate.

[0009] Preferably, the mounting plate has mounting holes, and the drip tube is inserted into the mounting holes. The detachable structure facilitates the maintenance and cleaning of the drip tube.

[0010] Preferably, one end of the mounting hole is provided with a baffle to limit the insertion depth of the drip tube, so as to ensure the fixed installation position of the mounting plate and the drip tube.

[0011] Preferably, a limiting platform is provided on the inner wall of the drip irrigation body. Multiple limiting platforms are evenly arranged along the inner wall of the drip irrigation body. The limiting platform is located at the end of the mounting plate away from the drip tube. When the mounting plate moves away from the channel opening, the mounting plate and the limiting platform will interfere. This allows the drip tube to be directly inserted through the channel opening without removing the drip irrigation body after it has been disassembled and pulled out. When the drip tube is inserted into the mounting hole, the mounting plate will be blocked by the limiting platform and will not be able to move further, thus facilitating the direct squeezing and insertion of the drip tube into the mounting hole.

[0012] Preferably, the drip irrigation body is provided with external threads, and the irrigation pipe is provided with internal threaded holes, and the drip irrigation body and the irrigation body are connected by threaded engagement.

[0013] Preferably, a regular hexagonal truncated pyramid is fixed to the outer wall of the drip irrigation body, and one end of the regular hexagonal truncated pyramid abuts against the outer wall of the irrigation pipe.

[0014] The technical effects of this utility model are as follows: By setting the internal structure of the drip irrigation body and the pressurization device, the flow rate of liquid can be limited under limited hydraulic pressure, and the liquid can only be discharged from the drip tube to form a drip irrigation effect; when the hydraulic pressure reaches a certain threshold, the mounting plate is squeezed to move. When the mounting plate moves to the flow area, the flow rate increases and is guided by the spray hole to form a dispersed spray effect, so as to realize two irrigation modes of spraying and drip irrigation, thereby improving irrigation efficiency and water resource utilization.

[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 dual-purpose sprinkler and drip irrigation head 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 bottom of the drip irrigation body 1 is provided with a rounded chamfer 16, and the arc surface of the rounded chamfer 16 is provided with a spray hole 17 whose axis is consistent with the diameter direction of the rounded chamfer 16 and is inclined downward in a direction away from the drip irrigation body 1. Multiple spray holes 17 are evenly provided along the circumference of the drip irrigation body 1.

[0024] Furthermore, a channel opening 13 is provided in the bottom of the drip irrigation body 1, and a drip tube 2 is inserted into the channel opening 13. The bottom end of the drip tube 2 passes through the channel opening 13, and its top end passes into the drip irrigation body 1 and its height is higher than the regular hexagonal truncated pyramid 15. An installation plate 21 is provided on it.

[0025] Furthermore, the mounting plate 21 and the inner wall of the drip irrigation body 1 are slidably connected and are configured without gaps between them, allowing them to move relative to each other along the drip irrigation body 1. The mounting plate 21 has a mounting hole 22, and a stop 23 is provided at the top of the mounting hole 22. The drip tube is inserted into the mounting hole 22 and its end presses against the stop 23. A limiting platform 24 is fixedly connected to the inner wall of the drip irrigation body 1. Multiple limiting platforms 24 are evenly arranged along the inner wall of the drip irrigation body 1. The limiting platforms 24 are located above the mounting plate 21. When the mounting plate 21 moves away from the channel opening 13 to a certain position, the mounting plate 21 and the limiting platform 24 will interfere with each other.

[0026] Furthermore, a spring is provided between the mounting plate and the bottom of the drip irrigation body, with the two ends of the spring 4 respectively abutting against the inner wall of the bottom of the mounting plate and the drip irrigation body.

[0027] Furthermore, the drip irrigation body 1 has a flow area 3 located in the region of the regular hexagonal frustum 15. The inner wall of the drip irrigation body 1 in the flow 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 21 moves into the flow area 3, a flow gap for liquid to pass through is always formed between the mounting plate 21 and the drip irrigation body 1.

[0028] Furthermore, a stop frame 32 is fixedly connected within the flow area 3. When the mounting plate 21 moves to a certain position, the mounting plate 21 and the stop frame 32 interfere with each other, and at this time the flow gap is opened. A guide sleeve 33 is fixedly connected to the center of the stop frame 32, and the drip tube is inserted into the guide sleeve 33.

[0029] 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 flows out through the drip tube 2 to achieve drip irrigation; when sprinkler irrigation is performed, the pressure pump works, and the water pressure squeezes the mounting plate 21. The mounting plate 21 resists the pressure of the spring and is pressed down to a certain position. The mounting plate 21 and the stop plate abut against each other, opening the flow gap. The water flows through the flow gap and sprays out from the spray hole 17; if the drip tube 2 needs to be cleaned, it can be pulled out directly and cleaned separately. When installing, the drip tube 2 is inserted through the channel 13. When the drip tube 2 is inserted into the mounting hole 22, the mounting plate 21 will be blocked by the limiting platform 24 and cannot continue to move, thus making it easy to directly squeeze the drip tube 2 into the mounting hole 22. The drip tube is inserted into the mounting hole 22 and its end abuts against the baffle 23.

[0030] 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.
