Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology and fluid control technology, specifically relating to a pressure regulating structure for a winch-type sprinkler irrigation machine. Background Technology

[0002] The pressure regulating structure of a winch-type sprinkler irrigation machine is a key component that ensures the stable and efficient operation of the sprinkler irrigation system under different working conditions. It ensures that the sprinkler irrigation machine can provide stable irrigation pressure under different working conditions, thereby achieving uniform irrigation effect, improving the growth quality and yield of crops, and avoiding energy waste caused by excessively high or low pressure.

[0003] In the existing technology, winch-type sprinkler irrigation machines are usually operated by electric drive. The pressure of the sprinkler system usually needs to be preset before operation. The preset pressure value is appropriate when the sprinkler irrigation machine starts to operate, but when moving the water pipe to irrigate a distant location, insufficient pressure may be encountered, which will result in insufficient spray pressure when moving to a distant location, thus affecting the uniformity and effectiveness of irrigation.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This is an embodiment of the present invention, which provides a pressure regulating structure for a winch-type sprinkler irrigation machine, including:

[0028] The water pipe body 100 includes a flexible hose 101, a first rigid pipe 102 connected to the flexible hose 101, a conduit 103 connected to the other end of the first rigid pipe 102, a second rigid pipe 104 connected to the other end of the conduit 103, an adjustment mechanism 200 disposed on the top of the conduit 103, and an auxiliary mechanism 300 disposed on the end of the second rigid pipe 104 away from the conduit 103.

[0029] The adjustment mechanism 200 includes a fixed frame 201 fixedly installed on the surface of the conduit 103, a cylinder 202 fixedly installed on the inner wall of the fixed frame 201, a sliding block 203 fixedly connected to the output end of the cylinder 202, a limiting groove 204 formed on the surface of the sliding block 203, a valve disc 205 rotatably connected to the inner wall of the conduit 103, and a limiting block 206 fixedly installed on the top of the valve disc 205 and used in conjunction with the limiting groove 204.

[0030] Specifically, a sealing gasket for use with valve disc 205 is fixedly connected to the inner surface of conduit 103, sliding block 203 is slidably connected to the inner surface of fixed frame 201, and bottom of limit block 206 is rotatably connected to the inner surface of conduit 103.

[0031] The valve disc 205 has the same inner diameter as the conduit 103, and its contact with the sealing gasket ensures that water will not flow out.

[0032] Furthermore, the auxiliary mechanism 300 includes a fixed plate 301 fixedly installed on the outer end face of the second rigid tube 104, a turntable 302 rotatably connected to the inner surface of the fixed plate 301, a first guide groove 303 formed on the surface of the turntable 302, and a second guide groove 304 formed on the surface of the fixed plate 301.

[0033] Furthermore, the auxiliary mechanism 300 also includes a sealing block 305 slidably connected to the inner wall of the first guide groove 303, a guide post 306 fixedly installed on the outer surface of the sealing block 305 and used in conjunction with the second guide groove 304, a handle 307 fixedly installed on the outer surface of the turntable 302, a friction block 308 fixedly installed on the outer surface of the turntable 302, a limiting component 309 provided on the outer surface of the fixed plate 301 and used in conjunction with the friction block 308, and a nozzle 310 fixedly installed on the outer surface of the fixed plate 301.

[0034] Furthermore, the throttle 307 extends to the outside of the fixed plate 301, and the outer surface of the throttle 307 slides in contact with the inner surface of the fixed plate 301.

[0035] Preferably, the limiting component 309 includes a shaped fixing block 309a fixedly installed on the outer surface of the fixing plate 301, a sliding column 309b slidably connected to the inner surface of the shaped fixing block 309a, a sleeve plate 309c fixedly sleeved on the outer surface of the sliding column 309b, a spring 309d sleeved on the outer surface of the sliding column 309b, and a friction plate 309e fixedly installed on the outer end face of the sliding column 309b and used in conjunction with the friction block 308.

[0036] It should be noted that one end of the spring 309d is fixedly connected to the outer surface of the sleeve 309c, and the other end of the spring 309d is fixedly connected to the outer surface of the irregular fixing block 309a.

[0037] The force of the spring 309d ensures that the sliding column 309b automatically resets without the influence of external force.

[0038] In use, when pressure adjustment is required, the cylinder is activated, causing the sliding block 203 to move linearly. As the sliding block 203 moves, it causes the limit block 206 to rotate, adjusting the pressure angle. When the adjusted angle releases the contact with the sealing gasket, water flows into the inner cavity of the second rigid pipe 104. The sleeve 309c is manually turned to release the friction plate 309e from the contact with the friction block 308. The handle 307 is then manually adjusted, causing the turntable 302 to rotate. 02 The rotation drives the sealing block 305 to expand outward in the first guide groove 303. At the same time, the guide post 306 slides in the second guide groove 304 to adjust the nozzle 310 diameter, completing the manual press adjustment. The sleeve 309c is released, and the sleeve 309c, due to the force of the spring 309d, causes the friction plate 309e on the outer end face of the sliding post 309b to be in contact with the friction block 308 again, ensuring that the handle 307 moves due to excessive pressure.

[0039] In summary, the coordinated operation of the various components in the regulating mechanism 200 ensures precise control of water pressure and flow rate. Furthermore, the auxiliary mechanism 300 allows operators to manually adjust the pressure of the sprinkler head without having to travel back and forth to readjust the pressure setting, ensuring sufficient spray pressure even at remote locations. The cooperation between the regulating mechanism 200 and the auxiliary mechanism 300 enhances the overall flexibility and reliability of the irrigation system.
