Description

Technical Field

[0001] The utility model belongs to the technical field of drip irrigation tape patch emitters, and specifically refers to a drip irrigation tape patch emitter with a double water inlet channel. Background Art

[0002] Irrigation is a technical measure to supplement the water required by crops. In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply sufficient water to crops. Under natural conditions, due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, it is necessary to artificially irrigate to make up for the deficiency of natural rainfall. Irrigation means watering the land. The irrigation principle is that the irrigation amount, irrigation frequency and time should be determined according to the water demand characteristics, growth stages, climate and soil conditions of medicinal plants, and it should be timely, appropriate and reasonable. Its types mainly include pre-sowing irrigation, seedling-promoting irrigation, growth-period irrigation and winter irrigation, etc. Drip irrigation is a way or means of irrigation.

[0003] At present, the buried drip irrigation tapes on the market only have a single-sided water inlet channel. When the channel is slowly blocked by sediment or other sundries in the pipeline, the holes are often blocked, resulting in insufficient water flow and low irrigation efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is:

[0005] The existing drip irrigation tape only has a single-sided water inlet and is prone to blocked holes.

[0006] To solve the above technical problem, the technical solution proposed by the utility model is: a drip irrigation tape patch emitter with a double water inlet channel, including a patch emitter body. The patch emitter body is integrally arranged in a stepped shape and is divided into an upper step and a lower step. One end of the back surface of the lower step is provided with a water outlet. One side of the water outlet is provided with two groups of water inlet channels. The two groups of water inlet channels are communicated through a connecting groove. The water outlet and the water inlet channels are communicated through a labyrinth flow channel. The water outlet and the labyrinth flow channel are communicated.

[0007] Furthermore, the upper step is provided with filter grooves arranged in a linear array. The connection part between the filter grooves and the water inlet channels forms water inlet through holes. The lower step is provided with water inlet holes arranged in a linear array. The water inlet holes are communicated with the water inlet channels.

[0008] Furthermore, a retaining platform is arranged at a position of the water outlet close to the labyrinth flow channel.

[0009] Furthermore, the back surface of the lower step is arranged in an arc shape.

[0010] Furthermore, the labyrinth flow channel is arranged in a V shape with two rows connected.

[0011] The beneficial effects obtained by the utility model adopting the above structure are as follows:

[0012] Add an additional water inlet channel at the water inlet position of the product, and set two groups of water inlet channels. When one of the water inlet channels is blocked by impurities and fine sand, the other water inlet channel can still work, thus ensuring the smooth operation of the drip irrigation tape, further ensuring the drip irrigation efficiency, and reducing the drip irrigation cost.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Such as Figures 1-3As shown in the figure, a patch drip head of a drip irrigation tape with a double water inlet channel proposed by the present utility model includes a patch drip head body 1. The patch drip head body 1 is integrally arranged in a stepped shape and is divided into an upper step 10 and a lower step 11. One end of the back surface of the lower step 11 is provided with a water outlet 2. On one side of the water outlet 2, there are two groups of water inlet channels 3. The two groups of water inlet channels 3 are communicated through a connecting groove 5. The water outlet 2 and the water inlet channels 3 are communicated through a labyrinth flow channel 4. The water outlet 2 and the labyrinth flow channel 4 are communicated. In order to achieve dual-channel water inlet, the upper step 10 is provided with filter grooves 6 arranged in a linear array. An inlet through hole 8 is formed at the connection between the filter grooves 6 and the water inlet channels 3. The lower step 11 is provided with water inlet holes 7 arranged in a linear array. The water inlet holes 7 are communicated with the water inlet channels 3.

[0020] In order to facilitate installation, reduce dirt blockage of the holes, and increase the obstruction of dirt, a retaining platform 9 is provided at a position of the water outlet 2 close to the labyrinth flow channel 4. In order to facilitate adaptation to the drip irrigation tape, the back surface of the lower step 11 is arranged in an arc shape. In order to reduce dirt from entering the water outlet 2 and blocking the water outlet holes, the labyrinth flow channel 4 is arranged in a V shape with two rows connected.

[0021] During specific use, understanding the deficiencies of the prior art, currently, the buried drip irrigation tapes on the market often have blocked holes, resulting in insufficient water flow and low irrigation efficiency. Based on the principles of chemistry, physics, mechanics, etc., this application starts from various angles such as shape, space, and structure among various products on the market. An additional water inlet channel is added at the water inlet position of the product. When one of the flow channels is blocked by debris, the other water inlet channel can still function normally, thereby ensuring the irrigation efficiency and reducing unnecessary losses of the irrigation system.

[0022] Fix the back surface of the lower step 11 on the inner wall of the drip irrigation tape, with the water outlet 2 facing the water outlet holes. Water flows into the two water inlet channels 3 from the water inlet holes 7 and the inlet through holes 8. The filter grooves 6 and the water inlet holes 7 will filter some of the debris in the water, reducing the possibility of impurities entering the water inlet channels 3. The water flows along the labyrinth flow channel 4 into the water outlet 2 and finally flows out from the water outlet holes of the drip irrigation tape for irrigation. The impurities entering the device will be intercepted and blocked in the labyrinth flow channel 4 to prevent blockage again. The above is the entire usage process of the patch drip head of the drip irrigation tape with a double water inlet channel.
