Description

Technical Field

[0001] The present invention relates to the field of irrigation nozzles, and particularly to a water and fertilizer irrigation spraying mechanism. Background Art

[0002] In agricultural production work, it is often necessary to apply water and fertilizer to crops to ensure their growth. The existing methods mostly irrigate by spraying water and fertilizer above the crops, so as to ensure the sprinkling of water and fertilizer and prevent the impact of water flow on the crops. However, the existing irrigation methods mostly rotate and spray water and fertilizer through a single-hole nozzle. Although it is simple and convenient, during the rotation of the single-hole nozzle, due to the basically constant water pressure, the landing point of the water flow forms a ring after rotation, resulting in the crops near the nozzle not being fully irrigated, causing uneven spraying of water and fertilizer and uneven growth of crops.

[0003] For example, an intelligent irrigation nozzle proposed in CN202311607648.0. Compared with the existing irrigation nozzles used for farmland and greenhouses, when water enters the nozzle body, it drives the impeller kit to rotate. During the rotation of the impeller kit, it drives the sleeve to reciprocate axially in the nozzle body. During the reciprocating sliding of the sleeve, several telescopic members drive several spheres to deflect. During the reciprocating deflection, the included angle between the jet holes on the spheres and the axis of the nozzle body changes periodically, and finally realizes the function of uniformly spraying and irrigating outward with the nozzle body as the center. Compared with the existing intelligent irrigation nozzles, it has the advantages of simple structure and low manufacturing cost, so it can be widely installed on the pipe network, and can obtain the water supply pressure in the nozzle body through the pressure detection module and control the water supply gear of the water pump, so as to adjust the change period of the elevation angle of the jet holes and the jet radius to achieve intelligent irrigation, but it does not completely solve the above problems.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the 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 only examples and are not intended to limit the present invention.

[0032] Next, a water and fertilizer irrigation injection mechanism according to an embodiment of the present invention will be described with reference to the accompanying drawings, as Figure 1 - Figure 9 shown. The water and fertilizer irrigation injection mechanism includes a rod body 1. A conical structure is provided below the rod body 1 for easy insertion and fixation. It also includes a support device provided at the lower end of the rod body 1; an adjustment device provided at the upper end of the rod body 1; and an injection device provided above the adjustment device.

[0033] As Figure 3 and Figure 4 shown, the water and fertilizer irrigation injection mechanism includes a support device. The support device includes a 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 plates 4 are rotatably and evenly distributed below the mounting ring 2. The fixing rod 5 is slidably mounted outside the support plate 4. A limiting spring 6 is fixed on the support plate 4. The lower end of the fixing rod 5 is provided with a conical structure, the upper end of the fixing rod 5 is provided with a flat head structure, and a chute that fits the fixing rod 5 is provided on the support plate 4, and a groove that fits the upper end of the fixing rod 5 is provided at the top of the chute.

[0034] In a specific embodiment: during use, the tightness of the mounting ring 2 is adjusted by rotating the threaded sleeve 3, so as to adjust the position of the support device on the rod body 1. After debugging to a suitable 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 supports on the ground, and the fixing rod 5 is pressed by the flat head structure at the upper end of the fixing rod 5 to insert the fixing rod 5 into the soil, so as to better support the rod body 1.

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

[0036] Such as Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown in

[0037] In a specific embodiment: during adjustment, by rotating the limiting plate, the limiting plate is disengaged from the upper part of the chute, and then the limiting plate is pulled down, driving the second clamping plate 10 to move downward and compressing the spring, so that the first clamping plate 9 is disengaged from the second clamping plate 10, and then the mounting rod 8 is rotated to make the first clamping plate 9 move downward, thereby adjusting the inclination angle of the mounting rod 8, and the connecting rod 7 can also be rotated to change the inclination direction of the mounting rod 8.

[0038] Such as Figure 2 、 Figure 7 、 Figure 8 and Figure 9As shown in the figure, the water and fertilizer irrigation spraying mechanism includes a spraying device. The spraying device 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 nozzle 19. The valve 14 is installed in the middle of the rod body 1. The housing 15 is installed above the mounting rod 8. The impeller 16 is rotatably installed at the bottom inside the housing 15. There is a partition 20 above the impeller 16. The partition 20 is provided with through holes. The reduction gear set 17 is arranged above the partition 20. The reduction gear set 17 is in transmission connection with the impeller 16. The turntable 18 is rotatably installed on the housing 15. The nozzle 19 is fixed to the turntable 18. The lower end of the turntable 18 is provided with a gear in transmission connection with the reduction gear set 17. The lower end of the turntable 18 is provided with an opening communicating with the nozzle 19. The middle of the nozzle 19 is provided with an arc structure. A plurality of spray holes are arranged on the outer side of the arc structure. One side of the lower end of the housing 15 is provided with an interface and is connected to one end of the valve 14 through a hose. The other end of the valve 14 is connected to a plug 12 through a hose. The sealing ring 13 is installed on the plug 12.

[0039] In a specific embodiment: During use, the plug 12 is connected to the pre-opened male pipe through the sealing ring 13 to supply water and fertilizer. Then the valve 14 is opened so that the water and fertilizer enter the housing 15 through the hose, thereby driving the impeller 16 to rotate. Then the turntable 18 is driven to rotate through the reduction gear set 17. At the same time, after the water and fertilizer enter the housing 15, they enter the nozzle 19 along the through holes on the partition 20 and are ejected from the multiple spray holes of the nozzle 19. Thus, under the rotation of the turntable 18, the water and fertilizer are sprayed in a rotating manner at multiple different positions.

[0040] Working principle: During use, the rod body 1 is inserted into the soil. Then the screw sleeve 3 is rotated to adjust the tightness of the mounting ring 2, thereby adjusting the position of the support device on the rod body 1. After adjusting to a suitable position, the screw 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 supports on the ground. And the flat head structure at the upper end of the fixing rod 5 is used to press the fixing rod 5 so that the fixing rod 5 is inserted into the soil. Then the plug 12 is connected to the pre-opened male pipe through the sealing ring 13 to supply water and fertilizer. Then the limiting plate is rotated, so that the limiting plate disengages from the upper part of the sliding groove. Then the limiting plate is pulled down, thereby driving the second clamping plate 10 to move downward and compressing the spring, so that the first clamping plate 9 disengages from the second clamping plate 10. Then the mounting rod 8 is rotated, so that the first clamping plate 9 moves downward, thereby adjusting the inclination angle of the mounting rod 8. The connecting rod 7 can also be rotated to change the inclination direction of the mounting rod 8. After adjusting to a suitable inclination angle and direction, the valve 14 is opened so that the water and fertilizer enter the housing 15 through the hose, thereby driving the impeller 16 to rotate. Then the turntable 18 is driven to rotate through the reduction gear set 17. At the same time, after the water and fertilizer enter the housing 15, they enter the nozzle 19 along the through holes on the partition 20 and are ejected from the multiple spray holes of the nozzle 19. Thus, under the rotation of the turntable 18, the water and fertilizer are sprayed in a rotating manner at multiple different positions.
