Description

Technical Field

[0001] This utility model relates to the field of cotton irrigation technology, and in particular to a cotton drip irrigation device. Background Technology

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of plants through orifices or drippers on capillary tubes with a diameter of about 10 mm. It is one of the most effective water-saving irrigation methods in arid and water-scarce areas.

[0003] Chinese patent document CN115316241 B discloses an insert-type drip irrigation device for crops, comprising: a drip irrigation pipe assembly and a protective cover assembly. The drip irrigation pipe assembly includes multiple drip irrigation pipes for drip irrigation of the soil around the roots of crops. The multiple drip irrigation pipes are arranged around the roots of the crops. The protective cover assembly is disposed on the drip irrigation pipe assembly to cover the soil around the roots, thereby reducing water evaporation. The protective cover assembly includes a protective cover body and a telescopic cover assembly, wherein the telescopic cover assembly can extend and retract to cover the soil around the roots. The advantages of this application compared to existing technologies are: it can evenly irrigate the area around the plant roots, improving irrigation efficiency, and it can retain soil moisture around the plant roots, reducing water evaporation and improving water use efficiency.

[0004] However, in actual use, the device requires a main pipe to connect multiple drip irrigation pipes to drip irrigate crops. However, when a water pipe is equipped with several branch pipes and the branch pipes are opened at the same time, the flow rate and velocity of the branch pipe at the front end of the water pipe are large, while the flow rate of the tap at the rear end is very small or even interrupted. This will result in different waters being received by crops located in different positions, making the device unstable during use. Utility Model Content

[0005] The main purpose of this invention is to provide a cotton drip irrigation device that can effectively solve the problem that different crops in different locations receive different amounts of water, making the device unstable during use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cotton drip irrigation device includes a water storage tank and a water pump, wherein the input end of the water pump is connected to the water storage tank;

[0008] A water supply pipe, the outer surface of which is provided with multiple drip irrigation components, and the water supply pipe and the drip irrigation components are connected through the drip irrigation components.

[0009] Preferably, a grounding rod is also fixed to the outer surface of the tee pipe.

[0010] Preferably, the drip irrigation assembly includes a connecting pipe, a sealing platform is fixed to the end of the connecting pipe away from the water supply pipe, a frustum-shaped groove is formed at one end of the sealing platform and the frustum-shaped groove communicates with the outside, an installation bracket is fixed to the side of the connecting pipe near the water supply pipe, a return spring is fixed to the end of the installation bracket away from the water supply pipe, a sealing frustum adapted to the sealing platform is also provided at the end of the return spring away from the installation bracket, a plurality of through grooves are formed on the outer surface of the sealing frustum, and a drip irrigation pipe is fixed to the end of the connecting pipe away from the tee pipe.

[0011] Preferably, when the return spring is in its natural state, the sealing frustum sidewall does not fit against the frustum-shaped groove sidewall.

[0012] Preferably, the drip irrigation pipe is S-shaped.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention employs a drip irrigation component design. Through the cooperation between the sealing frustum, the return spring, and the frustum-shaped groove, the device automatically controls the distance between the sealing frustum and the frustum-shaped groove according to the liquid flow rate, thereby controlling the amount of liquid entering the drip irrigation pipe. This ensures that the liquid flow rate entering the drip irrigation pipe remains constant regardless of changes in liquid flow rate or pressure. Furthermore, the drip irrigation pipe design prevents water from directly hitting the cotton roots after passing through the sealing frustum, thus avoiding damage to the cotton seedlings and increasing the stability of the device during use.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1As shown, a cotton drip irrigation device includes a water storage tank 1 and a water pump 2. The input end of the water pump 2 is connected to the water storage tank 1, and the output end of the water pump 2 is connected to a water delivery pipe 3, so that water in the water storage tank 1 can be delivered to the water delivery pipe 3. The water delivery pipe 3 has multiple drip irrigation components 5 on its outer surface. The drip irrigation components 5 are connected to the water delivery pipe 3 through a T-connector 4. The T-connector 4 is existing technology, which can facilitate the connection between multiple water delivery pipes 3 and facilitate the installation of the drip irrigation components 5 on the outer surface of the water delivery pipe 3.

[0021] In addition, a ground-insertion rod 6 is fixed to the outer surface of the three-way pipe 4. When the device is in use, the ground-insertion rod 6 is inserted next to the cotton seedlings to facilitate drip irrigation of the cotton seedlings. At the same time, it also serves to fix the three-way pipe 4 and prevent the position of the three-way pipe 4 from shifting, which would lead to inaccurate drip irrigation and waste of water resources.

[0022] like Figure 2 and Figure 3 As shown, the drip irrigation assembly 5 includes a connecting pipe 51, which is connected to a three-way pipe 4, allowing liquid passing through the three-way pipe 4 to enter the connecting pipe 51. A sealing platform 52 is fixed to the end of the inner surface of the connecting pipe 51 away from the water supply pipe 3. A frustum-shaped groove is formed at one end of the sealing platform 52, and the frustum-shaped groove communicates with the outside. A mounting bracket 53 is fixed to the side of the connecting pipe 51 near the water supply pipe 3. A return spring 54 is fixed to the end of the mounting bracket 53 away from the water supply pipe 3. The mounting bracket 53 is used to install the return spring 54. A sealing frustum 55 adapted to the sealing platform 52 is also provided at the end of the return spring 54 away from the mounting bracket 53. When the side wall of the sealing frustum 55 is in contact with the inner wall of the frustum-shaped groove, the sealing frustum 55 seals the frustum-shaped groove, and the liquid cannot be discharged from the connecting pipe 51.

[0023] In addition, multiple through grooves 56 are provided on the outer surface of the sealing frustum 55, so that when the side wall of the sealing frustum 55 is in contact with the inner wall of the frustum-shaped groove, the liquid can be discharged from the connecting pipe 51 through the through grooves 56 (at this time, the liquid pressure entering the connecting pipe 51 from the three-way pipe 4 is extremely high, and the liquid will push the sealing frustum 55 to move away from the three-way pipe 4, so that the side wall of the sealing frustum 55 is tightly in contact with the inner wall of the frustum-shaped groove. At this time, due to the design of the through grooves 56, a small amount of liquid will pass through multiple through grooves 56 and then be discharged into the drip irrigation pipe 57). The end of the connecting pipe 51 away from the three-way pipe 4 is also fixed with a drip irrigation pipe 57, wherein the drip irrigation pipe 57 is connected to the inside of the connecting pipe 51, so that the liquid in the connecting pipe 51 can enter the drip irrigation pipe 57, and then the drip irrigation pipe 57 drips to the side of the cotton seedling.

[0024] When the return spring 54 is in its natural state, the side wall of the sealing frustum 55 is not in contact with the side wall of the frustum-shaped groove. At this time, the flow rate and pressure of the liquid entering the connecting pipe 51 are relatively small. Because the gap between the sealing frustum 55 and the frustum-shaped groove is large, all the liquid passes through the frustum-shaped groove and then enters the drip irrigation pipe 57. When the flow rate and pressure of the liquid increase, the liquid pushes the sealing frustum 55 away from the mounting bracket 53, thereby shortening the distance between the side wall of the sealing frustum 55 and the side wall of the frustum-shaped groove. With the increased flow rate, a small portion of the liquid flows through the frustum-shaped groove into the drip irrigation pipe 57, while the remaining liquid stays in the connecting pipe 51. The device automatically controls the distance between the sealing frustum 55 and the frustum-shaped groove based on the liquid flow rate, thereby controlling the amount of liquid entering the drip irrigation pipe 57. This ensures that the flow rate of liquid entering the drip irrigation pipe 57 remains constant regardless of changes in flow rate and pressure, increasing the stability of the device during use. Figure 2 As shown, the drip irrigation pipe 57 is S-shaped. The S-shaped drip irrigation pipe 57 can store some liquid inside, which can prevent water from directly rushing to the roots of cotton after passing through the sealing platform 52, thereby causing damage to the cotton seedlings.

[0025] The specific implementation method of this embodiment is as follows: When using the device, first fill the water storage tank 1 with the liquid to be dripped (such as water, or a nutrient solution mixed with medicine), then start the water pump 2, the water pump 2 pumps the liquid into the water delivery pipe 3, and then enters the connecting pipe 51 through the three-way pipe 4. Due to the impact force during liquid transmission, the sealing frustum 55 is pushed to move away from the three-way pipe 4 (water with different pressures has different impact forces, so the distance the sealing frustum 55 moves is also different). Due to the design of the side wall of the sealing frustum 55 and the frustum-shaped groove cooperating with each other, the sealing frustum 55 is kept away from the installation support. The further away the bracket 53 is, the smaller the gap between the sealing frustum 55 and the frustum-shaped groove (when the water pressure increases, the distance between the sealing frustum 55 and the mounting bracket 53 will increase, thereby reducing the liquid flow rate accordingly; when the water pressure decreases, the distance between the sealing frustum 55 and the mounting bracket 53 will decrease, thereby increasing the liquid flow rate accordingly, so that the liquid flow rate entering the drip irrigation pipe 57 remains the same regardless of whether the liquid flow rate entering the connecting pipe 51 is large or small). This ensures that the water dripped onto multiple cotton balls is the same, making the device more stable and the drip irrigation more precise.

[0026] It should be noted that the specific installation methods, circuit connection methods, and control methods of the water pump 2, the three-way pipe 4, and the grounding rod 6 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
