Description

Technical Field

[0001] This invention relates to the field of sprinkler irrigation technology, specifically to a sprinkler head for sprinkler irrigation machines. Background Technology

[0002] A sprinkler irrigation machine sprays pressurized water into the air through specialized equipment, breaking it down into fine droplets that evenly sprinkle the fields like a light drizzle, providing water to crops, flowers, and seedlings. A sprinkler irrigation machine integrates pressurization, water delivery, spraying, and movement into a single, movable unit. Taking a hand-held lightweight sprinkler irrigation machine as an example, its structure mainly consists of a sprinkler head, sprinkler frame, water outlet pipe, power unit, water pump, water inlet pipe, filter screen, and frame. After the power unit drives the water pump, the impeller inside the pump, under the centrifugal force generated by its high-speed rotation, throws the water in the impeller channel outwards and forces it into the volute. A vacuum is created at the impeller inlet, and water from the pool or storage tank is drawn in along the suction pipe under atmospheric pressure, filling this space. The drawn-in water is then thrown out of the volute by the impeller, enters the water pipe, and is then forced into the sprinkler head, spraying it onto the crops in the field or pasture.

[0003] Existing sprinkler heads have certain drawbacks in actual use. For example, sprinklers generally spray water directly, and if chemicals need to be added, they need to be mixed at the source. However, this results in indiscriminate spraying of chemicals, making it impossible to add chemicals in the required amount. The only solution is to separate the water source and change the water location, which is inconvenient to operate. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows:

[0006] A sprinkler head for a sprinkler irrigation machine includes: an irrigation mechanism, a feeding mechanism, a feeding control mechanism, and an angle adjustment mechanism. The irrigation mechanism includes a main rod, a threaded ring disposed at the mounting end of the main rod, a water inlet pipe connected to the threaded ring for water supply, a sprinkler head connected to the main rod for irrigation, and a rocker arm mounted on the top of the main rod. The feeding mechanism includes a mounting block mounted on the sprinkler head, a side inlet formed in the inner wall of the sprinkler head for feeding, a feed pipe embedded in the mounting block and connected to the side inlet, a feed head connected to the feed pipe, a one-way valve mounted on the mounting block and connected to the feed head, and a feed pipe connected to the one-way valve for conveying feed. The feeding control mechanism is mounted on the path of the feed pipe for controlling the feeding of feed through the feed pipe. The angle adjustment mechanism is mounted on the threaded ring for adjusting the angle of the irrigation mechanism.

[0007] By adopting the above technical solution, the agent can be individually injected into the sprinkler head, and irrigation can be carried out differently according to the required area. Compared with the existing method of changing the water source, the agent application is more precise, the operation is more convenient, and the controllability is higher.

[0008] In a preferred embodiment, the present invention may be further configured such that: the material control mechanism includes a limiting plate installed on the outside of the material conveying pipe, an electric push rod fixed to the side of the limiting plate, a connecting plate connected to the driving end of the electric push rod, an mounting rod installed on the connecting plate, a pressing head connected to the mounting rod for controlling the extrusion of the material conveying pipe, and a limiting sleeve installed on the other side of the limiting plate to limit the connecting plate.

[0009] By adopting the above technical solution, the dosage of the feeding mechanism can be integrated and controlled, which is conducive to targeted drug use, convenient adjustment, and more rational.

[0010] In a preferred embodiment, the present invention may be further configured such that: the angle adjustment mechanism includes a positioning rod hinged to the middle of the threaded ring, a mounting base hinged to the other end of the positioning rod for positioning and installation, a double-headed push rod mounted on the mounting base, an adjusting rod hinged to the side of the threaded ring, a slide rail mounted inside the adjusting rod, and a hinge joint hinged to the output end of the double-headed push rod and engaged in the slide rail.

[0011] By adopting the above technical solution, the movement of the adjusting rod can be driven by the double-headed push rod, thereby tilting the main body of the sprinkler mechanism, changing the spraying angle of the sprinkler head, and the angle adjustment range is large, making it more practical.

[0012] In a preferred embodiment, the present invention may be further configured such that: the front end of the nozzle is detachably connected to an adjustment head, and a filter is installed on the inner side of the adjustment head.

[0013] By adopting the above technical solution, the irrigation area and water flow can be adjusted, making it easy to replace as needed.

[0014] In a preferred embodiment, the present invention may be further configured such that: an inner cavity is provided in the limiting plate for the material conveying pipe to be accommodated, and the diameter of the pushing head is equal to that of the top of the inner cavity.

[0015] By adopting the above technical solution, the feed pipe can be pre-fixed, which facilitates subsequent extrusion adjustment.

[0016] In a preferred embodiment, the present invention may be further configured such that: the mounting base has a mounting position for mounting the main rod on the sprinkler frame.

[0017] By adopting the above technical solution, the main rod can be installed on the sprinkler frame, making it convenient to use.

[0018] In a preferred embodiment, the present invention may be further configured such that the middle section of the feed pipe has a concave bend.

[0019] By adopting the above technical solutions, backflow pressure can be reduced and smooth material discharge can be ensured.

[0020] In a preferred embodiment, the present invention can be further configured such that both ends of the side inlet are located inside the nozzle, for carrying material out.

[0021] By adopting the above technical solution, the medicine can be carried into the nozzle by the side water flow and mixed, thereby reducing the water flow pressure.

[0022] The above-described technical solution of the present invention has the following beneficial technical effects:

[0023] 1. In this invention, the agent can be individually fed into the nozzle through the feeding mechanism, and irrigation can be carried out differently according to the required area. Compared with the existing method of changing the water source, the agent is more precise, easier to operate, more controllable, and easier to promote and use.

[0024] 2. In this invention, the dosage of the feeding mechanism can be integrated and controlled through the material control mechanism, which is conducive to targeted drug use by the feeding mechanism, convenient adjustment, and more reasonable.

[0025] 3. In this invention, the angle adjustment mechanism can drive the adjustment rod to move through the double-headed push rod, thereby tilting the main body of the sprinkler mechanism and changing the spray angle of the nozzle. Moreover, the angle adjustment range is large, making it more practical. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0037] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0038] The following describes, with reference to the accompanying drawings, some embodiments of a sprinkler head for an irrigation machine.

[0039] Example 1:

[0040] Combination Figure 1-4 As shown, the present invention provides a sprinkler head for a sprinkler irrigation machine, comprising: a sprinkler irrigation mechanism 100, a feeding mechanism 200, and a feeding control mechanism 300. The sprinkler irrigation mechanism 100 includes a main rod 110, a threaded ring 120 disposed at the mounting end of the main rod 110, a water inlet pipe 130 connected to the threaded ring 120 for water supply, a sprinkler head 140 connected through the main rod 110 for sprinkler irrigation, and a swing arm 150 installed on the top of the main rod 110. The main rod 110 is the main pipe. The threaded ring 120 can be unscrewed after being inserted into the water inlet pipe 130 for secondary fixation. The water inlet pipe 130 is connected through multiple sprinkler irrigation mechanisms 100. In use, water enters the main rod 110 through the water inlet pipe 130 and is then sprayed out through the sprinkler head 140. The swing arm 150 disperses the water flow sprayed from the sprinkler head 140, making the sprayed water flow a mist, which is an existing structure.

[0041] Furthermore, an adjustment head is detachably connected to the front end of the nozzle 140, and a filter 141 is installed inside the adjustment head. By installing the filter 141 inside the nozzle 140, some impurities can be filtered to prevent the end of the nozzle 140 from becoming clogged.

[0042] like Figure 1-3As shown, the feeding mechanism 200 includes a mounting block 210 installed on the nozzle 140, a side inlet 220 formed on the inner wall of the nozzle 140 for feeding, an inlet pipe 230 embedded in the mounting block 210 and passing through the side inlet 220, an inlet head 240 connected to the inlet pipe 230, a one-way valve 250 installed on the mounting block 210 and connected to the inlet head 240, and a conveying pipe 260 connected to the one-way valve 250 for conveying. The feeding mechanism 200 allows for the individual input of pesticides into the nozzle 140, enabling differentiated irrigation according to the required area. Compared to existing methods that change water sources, this method offers more precise pesticide application, easier operation, and higher controllability. Specifically, the mounting block 210 is detachably installed on the nozzle 140, and the inlet pipe 230 is installed on the mounting block 210. The nozzle 140 is connected to the hole on the side water outlet 220. Both ends of the side water outlet 220 are located inside the nozzle 140. It is used to carry the material out and facilitate the main water flow in the nozzle 140 to split off a portion of the water flow through the side water outlet 220, thereby mixing with the medicine discharged from the feed pipe 230 and entering the nozzle 140. This prevents the main water flow pressure from being too great and making it difficult for the medicine to be discharged, thus improving the rationality of the device. The one-way valve 250 is detachably installed on the mounting block 210. When it is necessary to clean and maintain the inside of the mounting block 210, the one-way valve 250 is unscrewed to allow the water flow in the nozzle 140 to enter the mounting block 210 to flush out the debris, which is quite convenient. The feed pipe 260 is also a series of feeding mechanisms 200 connected together, which can prepare materials at the same time, thus improving the rationality of the device.

[0043] Furthermore, the middle section of the feed pipe 230 is provided with a concave bend. This bend can reduce the backflow pressure of the feed pipe 230 to a certain extent, thereby improving the feasibility of the device.

[0044] like Figure 1 and 4 As shown, the material control mechanism 300 is installed on the path of the conveying pipe 260 to control the feeding of the conveying pipe 260. The material control mechanism 300 can be used to integrate and regulate the dosage of the feeding mechanism 200, which is conducive to the targeted use of the feeding mechanism 200 and easy to adjust.

[0045] Specifically, the material control mechanism 300 includes a limiting plate 310 installed on the outside of the conveying pipe 260, an electric push rod 320 fixed to the side of the limiting plate 310, a connecting plate 330 connected to the drive end of the electric push rod 320, a mounting rod 340 installed on the connecting plate 330, a push head 350 connected to the mounting rod 340 for controlling the extrusion of the conveying pipe 260, and a limiting sleeve 360 ​​installed on the other side of the limiting plate 310 to limit the connecting plate 330. The electric push rod 320 drives the connecting plate 360 ​​to move the connecting plate 330. The push head 350 installed on the 30 descends, thereby squeezing the conveying pipe 260 passing through the limiting plate 310. Squeezing to the bottom completes the closure of the conveying pipe 260. The amount of medicine can be controlled by adjusting the squeezing depth, which is more reasonable. Meanwhile, the limiting sleeve 360 ​​limits the movement of the connecting plate 330, ensuring that the connecting plate 330 moves stably up and down under the drive of the electric push rod 320. This improves the control of the amount of material used in the conveying pipe 260, thereby improving the rationality and feasibility of the device.

[0046] Furthermore, the limiting plate 310 has an inner cavity for accommodating the material conveying pipe 260, and the diameter of the pushing head 350 is equal to that of the top of the inner cavity. The limiting plate 310 can be used to initially fix the material conveying pipe 260 to achieve wire bundling.

[0047] Example 2:

[0048] Combination Figure 1 and 5 As shown, based on Embodiment 1, the angle adjustment mechanism 400 is installed on the threaded ring 120 for adjusting the angle of the irrigation mechanism 100. Through the angle adjustment mechanism 400, the double-headed push rod 430 can drive the adjustment rod 440 to move, thereby causing the main body of the irrigation mechanism 100 to tilt and change the irrigation angle of the nozzle 140. The angle adjustment range is large and the application range is wider.

[0049] Specifically, the angle adjustment mechanism 400 includes a positioning rod 410 hinged to the middle of the threaded ring 120, a mounting base 420 hinged to the other end of the positioning rod 410 for positioning and installation, a double-headed push rod 430 mounted on the mounting base 420, an adjusting rod 440 hinged to the side of the threaded ring 120, a slide rail 450 mounted inside the adjusting rod 440, and a hinge joint 460 hinged to the output end of the double-headed push rod 430 and locked in the slide rail 450. The mounting base 420 has a mounting position for mounting the main rod 110 on the sprinkler frame. The angle adjustment mechanism 400 can be adjusted via the mounting base 420. The sprinkler irrigation mechanisms 100 are installed side by side on the sprinkler irrigation machine mounting frame for unified irrigation. When adjusting the angle, the double-headed push rod 430 pushes the adjusting rod 440 to tilt through the connected hinge joint 460, which in turn drives the sprinkler irrigation mechanism 100 to move, changing the angle of the nozzle 140 and altering the irrigation path. The slide rail 450 allows the adjusting rod 440 on one side to move when the adjusting rod 440 on the other side moves, making the movement of the sprinkler irrigation mechanism 100 smoother. The positioning rod 410 improves the stability of the main body of the sprinkler irrigation mechanism 100.

[0050] The working principle and usage process of this invention are as follows: First, the sprinkler irrigation mechanism 100 is installed on the sprinkler irrigation machine mounting frame via the mounting base 420. Then, the water inlet pipe 130 is connected to the lower part of the threaded ring 120 to supply water. When the sprinkler irrigation angle needs to be adjusted, the double-headed push rod 430 drives the adjusting rod 440 to move, causing the sprinkler irrigation mechanism 100 to tilt. During irrigation, the water flow enters the interior of the main rod 110 through the water inlet pipe 130 and then sprays out from the nozzle 140. When it is necessary to apply pesticides to local areas, the electric push rod 320 drives the push head 350 to squeeze the feed pipe 260, closing the feeding mechanism 200 corresponding to the area that does not need pesticides. The pesticide enters the feed head 240 through the feed pipe 260 and the one-way valve 250, and then enters the interior of the side water outlet 220 along the feed pipe 230. As the water in the nozzle 140 sprays out, the angle adjustment mechanism 400 can be used to achieve swing irrigation during the spraying process, and the swing arm 150 can be used to disperse the water.
