Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation, in particular to a water applicator with segmented flow regulation. Background Art

[0002] The drip irrigation of crops generally uses plastic pipes to send water through water applicators on a capillary with a diameter of about 10 mm to the roots of crops for local irrigation. Drip irrigation can greatly improve the utilization rate of water resources, has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can combine fertilization to increase the fertilizer efficiency by more than double. It is applicable to fruit trees, vegetables, cash crops, and greenhouse irrigation, and can also be used for field crop irrigation in arid and water-scarce areas. The role of the water applicator is to cause energy loss after the water flow passes through the maze flow channel, reduce its pressure, and make it drip into the soil in a dripping manner.

[0003] At present, the phenomenon of mixed planting of many different types of plants with different water requirements is very common. The existing water applicators cannot achieve individual water output adjustment. They can only adjust the water output by adjusting the total valve or water pressure adjustment device of the drip irrigation system, resulting in a unified water output. The water output cannot be adjusted separately according to the water requirements of different plants, and there will be a situation of "adult's food being eaten by children and children's food being eaten by adults", causing problems such as excessive or too little water consumption of plants, which not only is not conducive to the growth of plants but also greatly reduces the effective utilization rate of water resources.

[0031] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific embodiments.

[0032] As Figure 1-8As shown in the figure, the utility model includes an upper housing 1, a lower housing 2 and an elastic labyrinth body 3. A receiving cavity 11 is arranged on the lower side of the upper housing 1, and a water inlet plug 12 for connecting a water pipe is arranged on the upper side. A water inlet channel 13 is arranged in the water inlet plug 12, and the water inlet channel 13 is communicated with the receiving cavity 11. A water storage chamber 21 is arranged on the upper side of the lower housing 2, and a water outlet channel 22 is arranged on one side of the lower housing 2. The elastic labyrinth body 3 is embedded in the receiving cavity 11 of the upper housing 1. The water storage chamber 21 of the lower housing 2 is inserted into the receiving cavity 11 to limit the elastic labyrinth body 3, and the lower housing 2 and the upper housing 1 are rotationally matched. The elastic labyrinth body 3 is limited by a limiting mechanism to realize synchronous rotation with the upper housing 1.

[0033] A labyrinth flow channel communicated with the water inlet channel 13 is arranged on the elastic labyrinth body 3. The labyrinth flow channel includes a straight turbulent flow section 31 arranged along the radial direction of the elastic labyrinth body 3 and an arc turbulent flow section 32 arranged along the circumferential direction of the elastic labyrinth body 3. The head end of the straight turbulent flow section 31 is communicated with the water inlet channel 13, and the tail end of the straight turbulent flow section 31 is communicated with the head end of the arc turbulent flow section 32. A plurality of water outlet through holes 33 matched with the water outlet channel 22 are arranged on the arc turbulent flow section 32. The apertures of the water outlet through holes 33 are different. Rotating the upper housing 1 or the lower housing 2 can make the water outlet channel 22 communicate with each water outlet through hole 33.

[0034] In this embodiment, there are four water outlet through holes 33. The length of the arc turbulent flow section 32 is three-quarters of a circle. A water outlet through hole 33 is arranged at each of the head end and the tail end of the arc turbulent flow section 32, and a water outlet through hole 33 is arranged at one-third and two-thirds of the arc turbulent flow section 32 respectively.

[0035] When adjusting the water outlet flow rate, by rotating the upper housing 1 or the lower housing 2, the water outlet channel 22 is communicated with the corresponding water outlet through hole 33. Every time it rotates 90°, a different water outlet through hole 33 is communicated with the water outlet channel 22. In order to facilitate accurately aligning and communicating the water outlet channel 22 with the water outlet through hole 33 when rotating the upper housing 1 or the lower housing 2, indicating letters A, B, C, D are arranged on the outer side wall of the upper housing 1 along its circumferential direction. The indicating letters A, B, C, D respectively correspond to the four water outlet through holes 33 inside and outside one by one. In this embodiment, the aperture of the water outlet through hole 33 indicated by the indicating letter A is 2 mm, and the corresponding water output is 12 L / h. The aperture of the water outlet through hole 33 indicated by the indicating letter B is 1.5 mm, and the corresponding water output is 8 L / h. The aperture of the water outlet through hole 33 indicated by the indicating letter C is 1 mm, and the corresponding water output is 4 L / h. The aperture of the water outlet through hole 33 indicated by the indicating letter D is 0.5 mm, and the corresponding water output is 2 L / h. In order to facilitate rotating the upper housing 1 or the lower housing 2, anti-slip patterns are arranged on the outer side wall of the upper housing 1 and the outer side wall of the lower housing 2.

[0036] In this embodiment, a limit card slot 14 is provided on the side wall of the accommodation cavity 11 of the upper housing 1, and a limit projection 23 is provided at the top end of the outer wall of the water storage chamber 21 of the lower housing 2. The limit projection 23 is fitted and snapped into the limit card slot 14 to connect the upper housing 1 and the lower housing 2 together.

[0037] The limiting mechanism includes two symmetric semi-circular bumps 15 provided at the bottom of the accommodation cavity 11, and two semi-circular card slots 34 which are matched with the semi-circular bumps 15 are provided on the elastic labyrinth body 3. The semi-circular bumps 15 are embedded into the semi-circular card slots 34 to realize the limitation of the elastic labyrinth body 3. The elastic labyrinth body 3 is made of silicone rubber.

[0038] During the specific irrigation operation, the irrigation water conveyed by the water delivery capillary enters the labyrinth flow channel through the water inlet channel 13. After the irrigation water fills the labyrinth flow channel, a part of the water enters the water outlet flow channel through one of the water outlet through holes 33 to flow out, and the other part enters the water storage chamber 21 through the other three water outlet through holes 33 until the water storage chamber 21 is filled with irrigation water. During normal operation, the water storage chamber 21 is always filled with water, which generates a force on the elastic labyrinth body 3. Therefore, it can offset part of the water pressure and play a role in pressure compensation and voltage stabilization. The irrigation water turbulently flows through the labyrinth flow channel and then stably flows out through the water outlet channel 22. According to the requirements of different plants for water consumption, the upper housing 1 or the lower housing 2 is rotated to adjust the water outlet position of the labyrinth flow channel. Since the apertures of the water outlet positions of the labyrinth flow channel are different, the purpose of adjusting the water output is achieved.

[0039] The utility model can realize the segmented adjustment of the water output flow by rotating the upper housing 1 or the lower housing 2. The operation is convenient, the water output can be adjusted according to the different water requirements of plants, the problem that the water output of the current water emitter cannot be adjusted is solved, which is beneficial to the growth of plants and improves the utilization rate of water resources.
