Detailed Description

As shown in fig. 1 to 6, an embodiment of the present utility model will be described in detail:

the utility model provides an irrigation shower nozzle, includes water supply pipe 11, support arm pipe 12 and injector head, and the lower extreme opening of water supply pipe 11, the upper end shutoff of water supply pipe 11, a plurality of support arm pipe 12 circumference evenly connect the side on water supply pipe 11 upper portion, and a plurality of injector heads are installed respectively in the end department of a plurality of support arm pipe 12.

When in use, the lower end of the water supply pipe 11 is connected with the water supply pipe, so that water enters the water supply pipe 11, and because the upper end of the water supply pipe 11 is blocked, the water flows into the plurality of support arm pipes 12 and is sprayed out through the plurality of spray heads for spray irrigation, and the water can be sprayed to the periphery uniformly in multiple directions through the uniform distribution of the plurality of spray heads, so that the spray irrigation area is increased compared with the traditional fixed spray heads.

Furthermore, the device can adapt to the sprinkling irrigation of different crops by adjusting the sprinkling state of the sprinkling head, such as sprinkling state or spraying state.

As shown in fig. 1-6:

the novel water supply pipe further comprises a connecting pipe 4, the upper end of the connecting pipe 4 is rotatably connected with the lower end of the water supply pipe 11, and the plurality of support arm pipes 12 are arc-shaped pipes.

Through the setting of connecting pipe 4, when using, the lower extreme of connecting pipe 4 is used for being connected with water supply end, because a plurality of support arm pipes 12 are the arced tube, so the spray head water spray direction of every support arm pipe 12 end is the horizontal direction and is crisscross with the central axis of connecting pipe 4, thereby when the spray head water spray, will produce the opposite force with the rivers direction, this force will be exerted on water pipe 11, make water pipe 11 rotate in the upper end of connecting pipe 4, thereby make a plurality of support arm pipes 12 when spraying water through the spray head, still use water pipe 11 as the axle rotation, and drive a plurality of support arm pipes 12 rotation, further enlarge the area that the device circumference sprinkling irrigation covered.

As shown in fig. 1-6:

the support leg comprises a support leg frame 1, a platform seat 2 and a fixing pipe 3, wherein the platform seat 2 is fixed at the upper end of the support leg frame 1, the fixing pipe 3 is fixed at the center of the platform seat 2, and the connecting pipe 4 is connected in the fixing pipe 3; the lower end of the supporting leg frame 1 is provided with a plurality of leg rods, and the lower end of each leg rod is provided with a conical tip.

The support leg frame 1 is used for supporting the platform seat 2, the platform seat 2 supports the connecting pipe 4 through the fixed pipe 3, and then the support for the water supply pipe 11 is formed;

moreover, by providing the lower ends of the plurality of leg bars with the taper points, the stability of the support of the leg frame 1 can be enhanced by using the taper points to prick into the ground in the field when the leg frame 1 supports the device.

As shown in fig. 1-6:

the eccentric cavity 5 is fixed on the connecting pipe 4 and is communicated with the connecting pipe 4, the rotating shaft 8 rotates at the center of the eccentric cavity 5, the cam plate 10 is fixed at one end of the rotating shaft 8, and the cam plate 10 is in sliding connection with the platform seat 2; the plurality of blades 9 are uniformly fixed on the rotating shaft 8, and the plurality of blades 9 are rotated in the eccentric cavity 5 and the connecting pipe 4.

When water flows in the connecting pipe 4 from bottom to top, the flowing water flows through the eccentric cavity 5, the flowing water flows push the blades 9 in the connecting pipe 4 to rotate upwards by taking the rotating shaft 8 as an axial direction, then the rotating shaft 8 is driven to rotate, and due to the arrangement of the blades 9, the blades 9 sequentially enter the connecting pipe 4 along with the pushing of the water flows, and the rotation of the rotating shaft 8 in the same direction is formed, so that the cam plate 10 is driven to rotate;

when the protrusion of the cam plate 10 rotates to the position of the platform seat 2, the cam plate 10 presses the platform seat 2 downwards, so that the eccentric cavity 5 is driven by the rotating shaft 8 to move upwards relative to the platform seat 2, namely the connecting pipe 4 slides upwards in the fixed pipe 3, then the connecting pipe 4 is driven to move upwards, the upper water pipe 11 moves upwards, the horizontal height of the spray head is improved, then the spray irrigation position is increased, and when the protrusion of the cam plate 10 rotates to the position of the platform seat 2, the connecting pipe 4 and the eccentric cavity 5 are subjected to self gravity, so that the connecting pipe 4 moves downwards in the fixed pipe 3, the horizontal height of the spray head is reduced, then the spray irrigation position is reduced, and the spray irrigation range is further enlarged through the reciprocating lifting transition of the horizontal position of the spray head.
