specific Embodiment approach 1

[0048] Combine below Figure 1-15Describe this embodiment, a self-rotating farmland irrigation nozzle with variable diameter, including a nozzle base 1, a rotating pipe 2, a nozzle pipe 3, a diameter reducing device 4, a nozzle 5 and a connecting piece 6, and the nozzle base 1 includes a bottom pipe 1 -1 and the socket head 1-2, the upper end of the bottom pipe 1-1 is welded and connected to the socket head 1-2, and the outer diameter of the socket head 1-2 is smaller than the outer diameter of the bottom pipe 1-1;

[0049] The rotating tube 2 includes a rotating tube body 2-1, an annular boss 2-2, a water outlet hole 2-3 and a plurality of rotating blades 2-4. The rotating tube body 2-1 is a cylindrical structure with an open lower end and a hollow interior. The lower end of the rotating tube body 2-1 is welded to the annular boss 2-2, the upper end of the side wall of the rotating tube body 2-1 is provided with a water outlet hole 2-3, and the middle end of the inner side wa...

specific Embodiment approach 2

[0055] Combine below Figure 1-15 Describe this embodiment, this embodiment will further explain the first embodiment, the outer side of the socket head 1-2 is provided with a sealing ring insertion groove I1-2-1, and the lower end of the inner wall of the rotating pipe body 2-1 is provided with Sealing ring inlay groove Ⅱ2-1-1, ring inlay groove Ⅰ1-2-1 is set opposite to ring inlay groove Ⅱ2-1-1, ring inlay groove Ⅰ1-2-1 is snapped into ring inlay groove Ⅱ2-1-1 There is a rubber sealing ring to ensure the sealing between the nozzle base 1 and the rotating tube 2 at one time, and the rubber sealing ring will not hinder the relative rotation between the nozzle base 1 and the rotating tube 2.

specific Embodiment approach 3

[0056] Combine below Figure 1-15 This embodiment will be described. This embodiment will further describe the first embodiment. The inserting sleeve 4-1 and a plurality of blades 4-2 constitute an impeller mechanism, and the rotation direction of the impeller mechanism is the same as that of the spiral chute 3-1. Similarly, when the blade 4-2 is subjected to the action of the water flow to rotate the diameter reducing device 4, the insertion column 4-5 can slide along the spiral chute 3-1.

Abstract

The present invention relates to the field of agricultural irrigation, more specifically, a variable-diameter self-rotating farmland irrigation nozzle, including a nozzle seat, a rotating pipe, a nozzle pipe, a diameter-changing device, a nozzle and a connecting piece; the nozzle pipe is provided with a spiral chute and rectangular chute, the number of turns of the spiral chute is one circle, and the two ends of the rectangular chute communicate with the upper and lower ends of the spiral chute; the diameter reducing device includes a socket sleeve, multiple blades, multiple supports Rod, variable-diameter plug core and plug-in column, multiple blades are arranged in the plug-in sleeve, the right end of the plug-in sleeve is connected to the variable-diameter plug core through a plurality of support rods, and the right end of the outer wall of the plug-in sleeve is provided with a plug-in column; A variable-diameter self-rotating sprinkler head for farmland irrigation, which has the beneficial effects of continuously changing the direction of sprinkling irrigation through self-rotation, and uniformly changing the distance of sprinkling irrigation and the range of sprinkling irrigation, which solves the problem of low service life of the sprinkler head and the range of sprinkling irrigation in the existing sprinkling irrigation technology. And the problem that the amount of sprinkler irrigation water is not easy to control.

Description

technical field [0001] The invention relates to the field of agricultural irrigation, in particular to a variable-diameter self-rotating sprinkler for farmland irrigation. Background technique [0002] Since there are many water-deficient areas in our country, the annual rainfall in individual areas is not enough to ensure agricultural production, so people usually use sprinkler irrigation or drip irrigation to irrigate crops. Sprinkler irrigation has been widely promoted due to its low irrigation cost and uniform irrigation. However, the sprinkler irrigation equipment on the market needs to be improved in the scope and uniformity of sprinkler irrigation. Therefore, people usually improve the sprinkler head to achieve the purpose of uniform irrigation. [0003] For example, the patent application number is CN201510287932.3, which is an evenly sprinkled irrigation sprinkler head, including a water spray device, an evenly sprinkled device and a pipe joint, the water spray devi...
