Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler irrigation machines, in particular to a water-saving and efficiency-enhancing nozzle of a DYP large-scale sprinkler irrigation machine. Background Art

[0002] A sprinkler is a machine that sprays water with a certain pressure into the air through a special machine and equipment from a nozzle, which is scattered into small water droplets and evenly sprinkled on the field like a drizzle to supply the water needs of crops, flowers, seedlings and other plants. The pressurization, water delivery, spraying, walking and other devices are connected into a movable whole, which is called a sprinkler. The structure of the machine is explained by taking a hand-lift light sprinkler as an example. It is mainly composed of a nozzle, a spray rack, a water outlet pipe, a power machine, a water pump, a water inlet pipe, a filter, a frame and the like. After the power machine drives the water pump to operate, the impeller in the pump is operated at a high speed. The centrifugal force generated, the water in the impeller flow channel is thrown around and pressed into the volute, and a vacuum is formed at the impeller inlet. The water in the pool or water tank is sucked along the suction pipe under the action of the external atmospheric pressure, which fills this space. Then the sucked water is thrown out of the volute by the impeller, enters the water pipe, and then pressed into the sprinkler to spray on the crops in the field or grassland.

[0003] A common sprinkler head on the market is a symmetrical structural design with a circular spraying range. Due to the symmetrical structural design, the spraying ranges on both sides are the same, and the spraying ranges are relatively repeated. There is more water in a certain circular range, and relatively speaking, there is less water in other parts of the circular range. For vegetation, the sprinkler irrigation effect does not meet the ideal requirements, nor does it achieve the requirements of spraying uniformity.

[0004] In summary, the utility model proposes a DYP large-scale sprinkler irrigation machine water-saving and efficiency-enhancing sprinkler head. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A DYP large-scale sprinkler water-saving and efficiency-enhancing nozzle comprises a water inlet pipe 1, characterized in that: one end of the water inlet pipe 1 is rotatably connected to a bevel gear 2, one end of the water inlet pipe 1 and located above the bevel gear 2 is fixedly connected to a bevel gear 2 3, one end of the water inlet pipe 1 close to the bevel gear 2 3 is fixedly connected to a rotating member 4, and one end of the rotating member 4 away from the bevel gear 2 3 is provided with an umbrella-shaped nozzle 5;

[0026] Example 1

[0027] See also Figure 1-4 In this embodiment, a common sprinkler head currently on the market is of symmetrical structural design, and the spraying range is circular. Due to the symmetrical structural design, the spraying ranges on both sides are the same, and the spraying ranges are relatively repeated. There is more water in a certain circular range, and relatively, there is less water in other circular ranges. For vegetation, the sprinkler irrigation effect does not meet the ideal requirements, nor does it meet the requirements of spraying uniformity.

[0028] In order to avoid the above situation, the nozzle is first connected to the water pipe through the threaded section of the water inlet pipe 1, so that the water in the water pipe passes through the water inlet pipe 1 and then sprayed out through the nozzle, which is beneficial to irrigating the crops.

[0029] When the sprinkler head is threadedly connected to the water pipe, the staff manually rotates the circular ring 3 8. Since the circular ring 3 8 is fixedly connected to the bottom end of the bevel gear 1 2, and the bevel gear 1 2 is rotationally connected to the water inlet pipe 1, the circular ring 3 8 is rotated to drive the bevel gear 1 2 to rotate, and the bevel gear 3 11 is meshed with the bevel gear 1 2 and the bevel gear 2 3 respectively, so that the bevel gear 1 2 is moved and the bevel gear 2 3 and the bevel gear 3 11 are rotated. Since the circular ring 2 70 is fixedly connected to the ratchet 2 72 through the connecting rod 2 71, and the circular ring 2 70 is fixedly connected to the bevel gear 2 3, the bevel gear 2 3 is moved and the ratchet 2 72 is driven to move in the ratchet 401, thereby limiting the water inlet. The angle of rotation of the umbrella-shaped sprinkler 5 is limited to prevent it from rotating, thereby reducing the possibility of repeated spraying range; in addition, the ring 160 is fixedly connected to the bevel gear 2 through a sleeve, and the ring 160 is fixedly connected to the pawl 162 through a connecting rod 161, while limiting the angle of rotation of the bevel gear 2, and further limiting the angle of rotation of the umbrella-shaped sprinkler 5, so that the umbrella-shaped sprinkler 5 can rotate unidirectionally, thereby achieving a more uniform water flow coverage area, ensuring that crops or plants can be fully irrigated or sprayed; at the same time, through the unidirectional rotation of the sprinkler, the direction and range of the water flow can be accurately controlled to avoid water waste, thereby achieving the effect of saving water and energy.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
