Description

Technical Field

[0001] This invention relates to the field of irrigation sprinklers, and more particularly to a water and fertilizer irrigation spraying mechanism. Background Technology

[0002] In agricultural production, it is often necessary to apply water and fertilizer to crops to ensure their growth. The existing method is mostly to spray water and fertilizer on the crops through irrigation, which ensures the application of water and fertilizer while preventing the water flow from impacting the crops. However, the existing irrigation method mostly uses a single nozzle to spray water and fertilizer in a rotating manner. Although simple and convenient, the water pressure is basically constant during the rotation of the single nozzle, which causes the water flow to form a ring after rotation. This results in the crops near the nozzle not receiving sufficient irrigation, leading to uneven water and fertilizer application and uneven crop growth.

[0003] For example, CN202311607648.0 proposes an intelligent irrigation sprinkler head. Compared to existing irrigation sprinklers used in farmland and greenhouses, this intelligent sprinkler head uses water flow to enter the sprinkler body, which drives the impeller assembly to rotate. During the rotation of the impeller assembly, the sleeve moves back and forth along its axis within the sprinkler body. During the reciprocating sliding of the sleeve, several telescopic components drive several spheres to deflect. During the reciprocating deflection, the angle between the jet holes on the spheres and the axis of the sprinkler body changes periodically, ultimately achieving the function of uniformly spraying irrigation outward with the sprinkler body as the center. Compared to existing intelligent irrigation sprinklers, this intelligent sprinkler head has the advantages of simple structure and low manufacturing cost, so it can be installed on a large scale in pipelines. It can also obtain the water supply pressure inside the sprinkler body through a pressure detection module and control the water pump's water supply level to adjust the jet hole elevation angle change period and jet radius, thereby achieving intelligent irrigation. However, it does not completely solve the aforementioned problems.

[0004] The present invention can rotate and spray at multiple different locations through the provided spraying device, so that the land near and far can be irrigated, thus making the water and fertilizer spraying more even. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are just examples and are not intended to limit the present invention.

[0032] The water and fertilizer irrigation spraying mechanism according to an embodiment of the present invention will now be described with reference to the accompanying drawings, such as... Figure 1 - Figure 9 As shown, the water and fertilizer irrigation spraying mechanism includes a rod 1 with a conical structure at the bottom for easy insertion and fixing. It also includes a support device at the lower end of the rod 1, an adjustment device at the upper end of the rod 1, and a spraying device above the adjustment device.

[0033] like Figure 3 and Figure 4 As shown, the water and fertilizer irrigation spraying mechanism includes a support device, which includes an mounting ring 2, a threaded sleeve 3, a support plate 4, and a fixing rod 5. The mounting ring 2 is slidably mounted on the rod body 1, the threaded sleeve 3 is mounted on the mounting ring 2, the support plate 4 is rotatably distributed below the mounting ring 2, and the fixing rod 5 is slidably mounted on the outside of the support plate 4. A limit spring 6 is fixed on the support plate 4. The lower end of the fixing rod 5 has a tapered structure, and the upper end of the fixing rod 5 has a flat head structure. The support plate 4 has a groove that fits with the fixing rod 5, and the top of the groove has a recess that fits with the upper end of the fixing rod 5.

[0034] In a specific embodiment: during use, the tightness of the mounting ring 2 is adjusted by rotating the threaded sleeve 3, thereby adjusting the position of the support device on the rod 1. After adjusting to the appropriate position, the threaded sleeve 3 is tightened to fix the mounting ring 2. Then, the support plate 4 is rotated to adjust the angle of the support plate 4, so that the support plate 4 is supported on the ground. The flat-head structure at the upper end of the fixing rod 5 is used to press the fixing rod 5 to insert the fixing rod 5 into the ground, thereby providing better support for the rod 1.

[0035] When storing, the fixed rod 5 is pulled up by the flat-head structure at the upper end of the fixed rod 5, which compresses the limiting spring 6. Then the fixed rod 5 is rotated so that the platform structure at the upper end of the fixed rod 5 is placed into the groove on the support plate 4, and the fixed rod 5 is fixed in a certain way by the elastic force of the limiting spring 6.

[0036] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the water and fertilizer irrigation spraying mechanism includes an adjustment device, which includes a connecting rod 7, a mounting rod 8, a first clamping plate 9, a second clamping plate 10, and a limiting block 11. The connecting rod 7 is rotatably mounted on the top of the rod body 1, and the mounting rod 8 is rotatably mounted on the top of the connecting rod 7. The first clamping plate 9 is slidably mounted inside the connecting rod 7, and a spring is provided between the first clamping plate 9 and the connecting rod 7. The second clamping plate 10 is slidably mounted inside the rod body 1, and the limiting block 11 is rotatably mounted on the second clamping plate 10. The lower end of the mounting rod 8 is provided with a gear structure, and the upper end of the first clamping plate 9 is provided with a toothed plate structure. The lower end of the first clamping plate 9 and the upper end of the second clamping plate 10 are provided with mutually meshing cam structures. The two ends of the limiting block 11 are slidably mounted on the rod body 1, and an "L"-shaped groove is opened on the rod body 1. The middle part of the second clamping plate 10 is provided with a limiting plate, and a spring is provided below the second clamping plate 10 to connect with the rod body 1.

[0037] In a specific embodiment: during adjustment, the limiting plate is rotated to disengage from the upper part of the slide groove, and then the limiting plate is pulled down to move the second clamping plate 10 downward and compress the spring, thereby disengaging the first clamping plate 9 from the second clamping plate 10. Then the mounting rod 8 is rotated to move the first clamping plate 9 downward, thereby adjusting the tilt angle of the mounting rod 8. The connecting rod 7 can also be rotated to change the tilt direction of the mounting rod 8.

[0038] like Figure 2 , Figure 7 , Figure 8 and Figure 9As shown, the water and fertilizer irrigation spraying mechanism includes a spraying device, which includes a plug 12, a sealing ring 13, a valve 14, a housing 15, an impeller 16, a reduction gear set 17, a turntable 18, and a spray pipe 19. The valve 14 is installed in the middle of the rod 1, the housing 15 is installed above the mounting rod 8, the impeller 16 is rotatably installed on the bottom inner side of the housing 15, a partition 20 is provided above the impeller 16, the partition 20 has a through hole, and the reduction gear set 17 is located above the partition 20. The reduction gear set 17 and the impeller 19 are connected. Wheel 16 is connected for transmission. Turntable 18 is rotatably mounted on housing 15. Spray pipe 19 is fixed on turntable 18. Gear is provided at the lower end of turntable 18 and is connected to reduction gear set 17 for transmission. Opening at the lower end of turntable 18 is provided to connect to spray pipe 19. Spray pipe 19 has an arc-shaped structure in the middle and multiple spray holes on the outer side of the arc-shaped structure. Interface is provided on one side of the lower end of housing 15 and is connected to one end of valve 14 through a hose. The other end of valve 14 is connected to plug 12 through a hose. Sealing ring 13 is installed on plug 12.

[0039] In a specific embodiment: during use, the pre-drilled male pipe is connected to the plug 12 and the sealing ring 13 to supply water and fertilizer. Then, the valve 14 is opened to allow water and fertilizer to enter the housing 15 through the hose, thereby driving the impeller 16 to rotate. In turn, the reduction gear set 17 drives the turntable 18 to rotate. At the same time, after the water and fertilizer enter the housing 15, they enter the spray pipe 19 through the through hole on the partition plate 20 and are sprayed out from multiple spray holes of the spray pipe 19. Thus, under the rotation of the turntable 18, multiple different positions are rotated and sprayed.

[0040] Working principle: In use, the rod 1 is inserted into the soil. Then, the tightness of the mounting ring 2 is adjusted by rotating the threaded sleeve 3, thereby adjusting the position of the support device on the rod 1. After adjusting to the appropriate position, the threaded sleeve 3 is tightened to fix the mounting ring 2. Then, the support plate 4 is rotated to adjust the angle of the support plate 4, so that the support plate 4 is supported on the ground. The flat-head structure at the upper end of the fixing rod 5 presses the fixing rod 5 to insert the fixing rod 5 into the soil. Then, the pre-drilled male pipe is connected to the plug 12 and the sealing ring 13 to supply water and fertilizer. Then, by rotating the limiting plate, the limiting plate is disengaged from the upper part of the slide groove. Then, the limiting plate is pulled down, thereby driving the second clamping plate 10 downward. The spring is moved and compressed, causing the first clamping plate 9 to disengage from the second clamping plate 10. Then, the mounting rod 8 is rotated, causing the first clamping plate 9 to move downward, thereby adjusting the tilt angle of the mounting rod 8. The connecting rod 7 can also be rotated to change the tilt direction of the mounting rod 8. After adjusting the appropriate tilt angle and direction, the valve 14 is opened to allow water and fertilizer to enter the housing 15 through the hose, thereby driving the impeller 16 to rotate. This, in turn, drives the turntable 18 to rotate through the reduction gear set 17. At the same time, after the water and fertilizer enter the housing 15, they enter the spray pipe 19 through the through hole on the partition plate 20 and are sprayed out from multiple spray holes in the spray pipe 19. Thus, under the rotation of the turntable 18, multiple different positions are rotated and sprayed.
