TECHNICAL FIELD

[0001] The utility model relates to the technical field of vegetable planting, and in particular to a water-saving drip irrigation device for vegetable planting. BACKGROUND

[0002] With global climate change and population growth, water resource shortage has become one of the important factors restricting the sustainable development of agriculture. Especially in the field of vegetable planting, traditional irrigation methods such as flooding irrigation and furrow irrigation not only consume a large amount of water, but also have low water use efficiency, which can easily cause soil salinization and water resource waste. In order to solve these problems, drip irrigation technology is gradually widely used because of its water-saving and efficient characteristics. Drip irrigation directly delivers water to the plant roots, reducing water evaporation and deep seepage, and improving irrigation efficiency.

[0003] However, the existing drip irrigation system still has some deficiencies in practical application. First of all, the water output of most drip irrigation devices is not flexible enough, and it is difficult to accurately control according to the different growth stages of crops and weather changes. Secondly, the traditional drip irrigation system often lacks effective water flow control mechanism, which affects the uniformity and stability of drip irrigation under high or low water pressure conditions. In addition, the structure of some drip irrigation equipment is complex, and the installation and maintenance cost is high, which limits its popularization among small-scale farmers. SUMMARY

[0004] The purpose of the utility model is to provide a water-saving drip irrigation device for vegetable planting to solve the problem that the traditional drip irrigation system cannot accurately control the irrigation amount under different water pressure conditions and has low water resource utilization efficiency.

[0005] To achieve the above purpose, a water-saving drip irrigation device for vegetable planting is provided, which comprises a water outlet mechanism, a plurality of symmetrically arranged drip irrigation mechanisms are arranged on one side of the water outlet mechanism, the drip irrigation mechanisms are connected in communication through a third connecting pipe, the drip irrigation mechanism comprises a plurality of shower heads, an elastic control mechanism is arranged at the upper end of the drip irrigation mechanism inside the third connecting pipe, the elastic control mechanism comprises a plurality of water plugging columns arranged inside the third connecting pipe, and each water plugging column is arranged corresponding to each shower head.

[0006] As a further improvement of the technical scheme, the elastic control mechanism further comprises a sliding plate arranged at the upper end of the water plugging column, and the sliding plate is fixedly connected with a spring in the direction of the water outlet mechanism in the pipe.

[0007] As a further improvement of the technical scheme, the third connecting pipe comprises an inner cavity, a fixed block is fixedly connected with the spring at the corresponding position of the spring, and the fixed block is fixedly connected with the spring.

[0008] As a further improvement of the technical solution, the water outlet mechanism comprises a water tank arranged at one side of the drip irrigation mechanism, the water tank is connected with a water pump at one side of the drip irrigation mechanism through a first connecting pipe, and the other end of the water pump is communicated with the drip irrigation mechanism in the third connecting pipe through a second connecting pipe.

[0009] As a further improvement of the technical solution, the third connecting pipe is connected with a fourth connecting pipe at the other end, and the fourth connecting pipe is communicated with the water tank at the other end.

[0010] Compared with the prior art, the utility model has the advantages of:

[0011] 1、The water-saving drip irrigation device for vegetable planting, through the design of the elastic control mechanism and the sliding plate, the drip irrigation water volume can be flexibly adjusted according to the actual demand of crops and external environmental conditions. When it is necessary to increase the irrigation volume, the power of the water pump is enhanced to push the sliding plate to move, so that the water blocking column is moved away from the water leakage hole, and the number of water leakage holes is increased. Conversely, when it is necessary to reduce the irrigation volume, the power of the water pump is reduced, so that the sliding plate is reset under the action of the spring tension, and the water blocking column reseals part of the water leakage hole. This precise control mechanism not only ensures that the crops are supplied with appropriate water, but also effectively avoids the waste of water resources and improves the overall water resource utilization efficiency.

[0012] 2、The water-saving drip irrigation device for vegetable planting, through the design of the elastic control mechanism and the sliding plate, the drip irrigation water volume can be flexibly adjusted according to the actual demand of crops and external environmental conditions. When it is necessary to increase the irrigation volume, the power of the water pump is enhanced to push the sliding plate to move, so that the water blocking column is moved away from the water leakage hole, and the number of water leakage holes is increased. Conversely, when it is necessary to reduce the irrigation volume, the power of the water pump is reduced, so that the sliding plate is reset under the action of the spring tension, and the water blocking column reseals part of the water leakage hole.

Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0021] Please refer to Figs. 1-3 The present embodiment aims to provide a water-saving drip irrigation device for vegetable planting, which comprises a water tank 1, a first connecting pipe 2, a water pump 3, a second connecting pipe 4, a drip irrigation mechanism 5, a shower head 6, a third connecting pipe 7, a fourth connecting pipe 8, an elastic control mechanism 9, an inner cavity 10, a fixed block 11, a spring 12, a sliding plate 13 and a water blocking column 14. Through the coordinated work of these components, the efficient, flexible and water-saving drip irrigation function is realized.

[0022] In terms of specific structure, the water tank 1 serves as a water source storage device and is located on one side of the drip irrigation mechanism 5. The water tank 1 is connected to the water pump 3 through the first connecting pipe 2, and the water pump 3 functions to draw water out of the water tank 1 and deliver it to the drip irrigation mechanism 5 in the third connecting pipe 7 through the second connecting pipe 4. The drip irrigation mechanism 5 is symmetrically arranged on one side of the water outlet mechanism 15, and each drip irrigation mechanism 5 contains several shower heads 6 for uniformly distributing water flow to the plant roots.

[0023] An elastic control mechanism 9 is provided inside the third connecting pipe 7, which includes a plurality of water blocking columns 14, each corresponding to a respective sprinkler 6. The upper end of each water blocking column 14 is provided with a sliding plate 13, which is fixedly connected with a spring 12 inside the pipe towards the water outlet mechanism 15. When the impact force of the water flow provided by the water pump 3 increases, the water flow will push the sliding plate 13 to move, causing the water blocking column 14 to move away from the water leakage hole, increasing the number of water leakage holes and thus increasing the amount of drip irrigation. This design ensures that when more water is needed, the irrigation amount can be quickly increased.

[0024] Conversely, when it is necessary to reduce the amount of drip irrigation water, the power of the water pump 3 can be reduced to reduce the impact force of the water. At this time, under the action of the pulling force of the spring 12, the sliding plate 13 will be pulled back to the initial position, and the water blocking column 14 will reseal part of the water leakage hole, reducing the overall flow of drip irrigation. In this way, even under different irrigation needs, precise control can be achieved to avoid waste of water resources.

[0025] In addition, the third connecting pipe 7 also includes an inner cavity 10, and a fixed block 11 is fixedly connected at the corresponding position of the spring 12, and the fixed block 11 is fixedly connected with the spring 12 to ensure that the spring 12 remains stable during operation. The other end of the third connecting pipe 7 is connected with a fourth connecting pipe 8, and the other end of the fourth connecting pipe 8 is connected to the water tank 1, forming a circulation system, so that the unused water can be returned to the water tank 1, further improving the utilization rate of water resources.

[0026] The installation and maintenance of the device are very convenient. Through the above design, not only the intelligent adjustment of the amount of drip irrigation water is achieved, but also the flexibility of irrigation and the efficiency of water resource utilization are greatly improved, which is very suitable for application in various vegetable planting bases.

[0027] Working principle: The water in the water tank 1 is pumped out by the water pump 3 through the first connecting pipe 2, and is sent into the drip irrigation mechanism 5 in the third connecting pipe 7 through the second connecting pipe 4. Inside the third connecting pipe 7, the elastic control mechanism 9 adjusts the position of the water blocking column 14 through the action of the sliding plate 13 and the spring 12 according to the impact force of the water flow. When the water pressure provided by the water pump 3 increases, the water flow pushes the sliding plate 13 to move, causing the water blocking column 14 to move away from the water leakage hole, increasing the number of water leakage holes and the area of the water leakage holes, thereby increasing the amount of drip irrigation water. Conversely, when it is necessary to reduce the amount of drip irrigation water, the power of the water pump 3 is reduced, the impact force of the water flow is reduced, and under the action of the pulling force of the spring 12, the sliding plate 13 is reset, and the water blocking column 14 reseals part of the water leakage hole, reducing the flow of drip irrigation. In addition, the fourth connecting pipe 8 returns the unused water to the water tank 1, forming a circulation system, further improving the utilization efficiency of water resources. Through this intelligent adjustment mechanism, the device can flexibly and accurately control the amount of drip irrigation water, ensuring that crops receive an appropriate amount of water supply.

It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
