Description

Technical Field

[0001] The utility model relates to the technical field of irrigation and fertilization, in particular to an irrigation and fertilization device. Background Art

[0002] The process of fertilizer entering the field along with irrigation water is called fertigation. That is, while irrigating with water, drip irrigation, underground drip irrigation, etc., accurately add fertilizer and evenly apply it near the root system according to the nutrient needs of the crop at each growth stage and climatic conditions, and the root system directly absorbs and utilizes it. Fertigation can improve the utilization rate of fertilizers, save fertilizer usage, save labor for fertilization, flexibly, conveniently and accurately control the time and amount of fertilization, quickly absorb nutrients, improve the environmental conditions of the soil, and be particularly suitable for the application of trace elements, maximize the benefits of water and fertilizer, and help protect the environment.

[0003] Fertilization is often used in field crops, vegetable crops and fruit and vegetable crops. Commonly used fertigation devices include a liquid storage tank, a pressure pump and a drip irrigation pipe. The pump inlet of the pressure pump is connected to the liquid storage tank, and the pump outlet of the pressure pump is connected to the drip irrigation pipe. Some drip irrigation pipes are provided with multiple drippers at intervals, that is, drip irrigation technology. Drip irrigation uses plastic pipes to send water to the roots of crops through the orifices or drippers on the capillary tube with a diameter of about 10 mm for local irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation. At the same time, it can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas. Its disadvantage is that the dripper is easy to scale and clog because calcium carbonate, magnesium hydroxide and other impurities will precipitate in the water source to form scale, and there is also clogging of fertilizer sediment, so the water source should be strictly filtered and purified.

[0004] The dripper blockage of the drip irrigation system is also caused by biological blockage, such as the invasion of crop roots into the drip irrigation holes. The hydrotropism of crop roots and unbalanced irrigation will cause the roots to grow toward the drip irrigation holes. The dripper holes are usually small, and crop roots can easily extend into the dripper holes, causing the dripper blockage. The water source used for irrigation and fertilization is usually a natural water source, such as river water and well water. To deal with the blockage of drippers caused by water quality, the use of filtration and purification equipment to treat natural water sources is heavy and costly. Utility Model Content

[0005] The utility model aims to provide an irrigation and fertilization device to improve the problem that the drippers in the drip irrigation system are easily blocked by the crop roots.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0021] Example 1

[0022] An irrigation and fertilization device, referring to Figure 1 , Figure 2, including a liquid storage tank 1, a pressure pump 2 and a water pipe 3 which are connected in sequence. The liquid storage tank 1 is connected to the pressure pump 2 through a pipeline. A plurality of drain components are arranged at intervals on the water pipe 3. The drain component includes a drain pipe 4. One end of the drain pipe 4 is connected to the outer wall of the water pipe 3. A connecting rod 5 is arranged on the drain pipe 4. A mounting plate 6 is arranged on the connecting rod 5. The mounting plate 6 is located at one end of the drain pipe 4 away from the water pipe 3, and a distance is left between the mounting plate 6 and the drain pipe 4. A spring 7 is arranged on the mounting plate 6. A sealing block 8 is provided at one end of the spring 7 away from the mounting plate 6, and the sealing block 8 is used to block the water outlet of the drain pipe 4; a drain cylinder 9 is provided on the sealing block 8, the drain cylinder 9 extends into the drain pipe 4, and the drain cylinder 9 and the inner wall of the drain pipe 4 slide together along the central axis direction of the drain pipe 4, a drain hole 10 is provided on the side wall of the drain cylinder 9, and an installation groove is provided on the outer wall of the drain cylinder 9 above the drain hole 10, and a sealing ring 11 is provided in the installation groove, and a sliding seal is formed between the sealing ring 11 and the inner wall of the drain pipe 4.

[0023] When using the fertilization device, first assemble the fertilization device, then lay the water pipe 3 in the area to be irrigated and fertilized, so that multiple waterproof components are located above the area to be irrigated, then add water to the liquid storage tank 1, and dissolve the fertilizer in the liquid storage tank 1, start the pressure pump 2, and the pressure pump 2 transports the mixed liquid to multiple water discharge components through the water pipe 3. The water pressure inside the water discharge pipe 4 squeezes the sealing block 8, so that the sealing block 8 and the water discharge cylinder 9 move downward, the spring 7 is compressed, and the water discharge hole 10 on the water discharge cylinder 9 is exposed from the water discharge pipe 4, and the water is discharged. The water in the water pipe 4 can drip and discharge to the ground through the drain hole 10 on the drain cylinder 9, thereby realizing irrigation; when the irrigation is finished, the pressure pump 2 is turned off, the water pressure in the drain pipe 4 gradually decreases to zero, and the drain cylinder 9 and the sealing block 8 move upward under the action of the spring 7, so that the drain hole 10 of the drain cylinder 9 moves to the position inside the drain pipe 4. At this time, the sealing block 8 and the drain pipe 4 can seal and protect the drain hole 10 of the drain cylinder 9, which can reduce the situation where the crop roots extend into the drain hole 10 and cause the drain hole 10 to be blocked.

[0024] Further, refer to Figure 1 , Figure 2, a threaded hole is provided on the mounting plate 6, and an adjusting bolt 12 is connected to the thread in the threaded hole. The head of the adjusting bolt 12 is located on the side of the mounting plate 6 away from the drain pipe 4, and the other end passes through the mounting plate 6 and faces the sealing block 8; the side wall of the drain cylinder 9 is provided with a plurality of drain holes 10 along the length direction of the drain cylinder 9, and the plurality of drain holes 10 are all located below the sealing ring 11. Since the amount of water and fertilizer required by different crops is different, the distance between the adjusting bolt 12 and the outlet of the drain pipe 4 can be changed by rotating the adjusting bolt 12, and then the limit position of the downward movement of the sealing block 8 can be adjusted, and then the number of drain holes 10 on the drain cylinder 9 exposed to the drain pipe 4 can be adjusted, and then the irrigation flow of the corresponding irrigation part can be adjusted. The more water and fertilizer are required, the more drain holes 10 can be exposed. It should be noted that when the distance between the adjusting bolt 12 and the sealing block 8 is far enough, the booster pump 2 is started, and all the drain holes 10 on the drain cylinder 9 can be exposed outside the drain pipe 4.

[0025] Further, refer to Figure 1 , Figure 2 A groove 13 is provided on the side of the sealing block 8 away from the drain pipe 4, and the end of the spring 7 close to the sealing block 8 is connected to the inner bottom wall of the groove 13. A protective tube 14 is provided on the mounting plate 6, and the end of the protective tube 14 away from the mounting plate 6 extends into the groove 13. There is a gap between the protective tube 14 and the inner bottom wall of the groove 13, and the protective tube 14 is sleeved on the outside of the spring 7. The spring 7 is connected to the inner wall of the groove 13 below the sealing block 8, which can reduce the situation where water flows onto the spring 7. The protective tube 14 can also protect the spring 7 and reduce the situation where the spring 7 rusts due to too much water. In addition, since there is a gap between the protective tube 14 and the inner bottom wall of the groove 13, when the adjusting bolt 12 is turned downward, the sealing block 8 can be easily moved downward under the action of the water pressure inside the drain pipe 4.

[0026] Further, refer to Figure 1 , Figure 2 The adjusting bolt 12 and the mounting plate 6 are both made of plastic. Since the adjusting bolt 12 and the mounting plate 6 are close to the ground, the threaded holes of the adjusting bolt 12 and the mounting plate 6 are easily stained with water during irrigation and rain. The use of plastic material can prevent the adjusting bolt 12 and the mounting plate 6 from rusting.

[0027] Further, refer to Figure 1 , Figure 2 The end of the water pipe 3 away from the pressure pump 2 is connected to the liquid storage tank 1, and the conventional drip irrigation pipe or water pipe 3 is not directly connected to the liquid storage tank 1. The advantage of this is that the mixed liquid containing fertilizer can be kept flowing in the water pipe 3, which is conducive to reducing the precipitation of fertilizers and other substances in the mixture in the water pipe 3 and thus clogging the water discharge hole 10 of the water discharge barrel 9.

[0028] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
