Description

Technical Field

[0001] This application relates to the field of irrigation technology, and more specifically, to water-saving irrigation devices for agricultural technology. Background Technology

[0002] In agricultural planting, external equipment is needed to irrigate crops. Existing patent document CN215957571U discloses a water-saving irrigation device for agricultural technology promotion. This device, through a novel water-saving structure, allows irrigation water to directly enter the soil around the crop roots through a buried pipe, resulting in minimal water remaining on the surface. This reduces evaporation, saving water consumption and improving water utilization. The central rod structure allows the device to be sealed when not in use, reducing the risk of crop roots entering the buried pipe and preventing blockages, thus increasing its practicality. However, despite these advantages, the device still has the following drawback: it cannot be shut off promptly after the soil becomes wet, resulting in a relatively poor water-saving effect.

[0003] The prior art publication CN 217184185 U provides a water-saving irrigation device for agricultural technology promotion. This device uses a water-absorbing and expanding material in the filter box. When water diffuses in the soil, the water-absorbing and expanding material absorbs water from the soil and expands, pushing a piston to seal the connecting pipe A, thereby controlling the amount of irrigation water. This solves the problem that the original device could not be shut off in time after the soil was wetted, resulting in poor water-saving effect.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] Superabsorbent polymer (SAP) is a polymer with a certain degree of cross-linking. It can quickly absorb hundreds of times more water than its own weight to form a gel. This gel can retain moisture under certain pressure and does not separate. Therefore, SAP is not easy to dehydrate, which leads to the problem of irreversibility. As a result, the connecting tube is always in a closed state and cannot be used normally.

[0006] In view of this, we propose a water-saving irrigation device for agricultural technology. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of this application is to provide a water-saving irrigation device for agricultural technology, which solves the technical problems mentioned in the background art and achieves a better technical effect in terms of the opening and closing effect of the connecting pipe.

[0009] 2. Technical Solution

[0010] This application provides a water-saving irrigation device for agricultural technology, including a water supply pipe and multiple connecting pipes with drainage holes. Multiple branch pipes are connected through the water supply pipe, and vertical pipes are connected through the branch pipes. A water storage tank is connected through the lower end of the vertical pipe. An L-pipe is connected through one side of the water storage tank, and a water collection hopper placed directly below the connecting pipe is connected through the L-pipe. Multiple thin absorbent cotton ropes are installed at the bottom of the water storage tank. A float is installed inside the water storage tank, and a piston rod that slides into the vertical pipe is fixed to the float. The piston rod has a water outlet hole that is coaxial with the branch pipe.

[0011] By adopting the above technical solution, the float drives the piston rod to descend, and the water outlet and branch pipe are connected accordingly. Then, water is used to irrigate the soil through the drainage hole of the connecting pipe. During the irrigation process, after the soil is thoroughly irrigated, excess water will seep into the water collection hopper under the action of gravity, and then flow back into the water storage tank through the L-pipe. When the rate of return is greater than the water absorption rate of the thin absorbent cotton rope, the water level in the water storage tank rises, supporting the piston rod upward and causing the water outlet to rise. At this time, the piston rod blocks the branch pipe, which can realize the automatic closure of the branch pipe. When the thin absorbent cotton rope gradually absorbs water and wets the soil, the water level in the water storage tank drops, the float and piston rod descend, and the water outlet aligns with the branch pipe, which can then be reopened.

[0012] As an optional solution to the technical solution in this application, guide rods are symmetrically fixed inside the water storage tank, and guide holes adapted to the guide rods are symmetrically opened on the float.

[0013] By adopting the above technical solution, and through the cooperation of the guide rod and the guide hole, when the float is a cylindrical structure, it can guide the float when it floats up and down, thus avoiding the misalignment of the water outlet and the branch pipe.

[0014] As an optional solution to the technical solution of this application, a limiting plate is fixed on the guide rod. The limiting plate is larger than the inner diameter of the guide hole. The limiting plate is placed at the upper end of the connection between the L-tube and the water storage tank. The water storage tank is placed in the area below the limiting plate to form a sedimentation tank.

[0015] By adopting the above technical solution, when the lower surface of the float abuts against the limiting plate, the water outlet corresponds to the branch pipe, and the lower end opening of the L-pipe is placed below the float, while a sedimentation tank is formed below to facilitate the sedimentation of sludge.

[0016] As an optional solution to the technical solution in this application, the water collection hopper is an inverted frustum-shaped structure.

[0017] By adopting the above technical solution, an inverted frustum-shaped water collection hopper is used to facilitate the centralized recycling of water.

[0018] As an optional solution to the technical solution in this application, a filter plate is fixed to the upper opening of the water collection hopper, and filter cotton is fixed to the lower surface of the filter plate.

[0019] By adopting the above technical solution, a filter plate is used to intercept large particles, and then a filter cotton is used to intercept small particles, thus avoiding blockage of the L-tube.

[0020] 3. Beneficial effects

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] 1. This application uses a float to drive a piston rod to descend, with the outlet and branch pipe connected accordingly. Water is then used to irrigate the soil through the drain hole of the connecting pipe. During irrigation, excess water seeps into the sump under gravity after the soil is thoroughly irrigated, and then flows back into the storage tank through the L-pipe. When the rate of return is greater than the absorption rate of the absorbent cotton rope, the water level in the storage tank rises, supporting the piston rod upward and causing the outlet to rise. At this time, the piston rod blocks the branch pipe, thus automatically closing the branch pipe. When the absorbent cotton rope gradually absorbs water and wets the soil, the water level in the storage tank drops, the float and piston rod descend, and the outlet aligns with the branch pipe, allowing it to reopen.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] A water-saving irrigation device for agricultural technology includes a water supply pipe 1 and multiple connecting pipes 2 with drainage holes 21. Multiple branch pipes 3 are connected through the water supply pipe 1. A vertical pipe 4 is connected through the branch pipes 3. A water storage tank 5 is connected through the lower end of the vertical pipe 4. An L-pipe 61 is connected through one side of the water storage tank 5. A water collection hopper 6 located directly below the connecting pipe 2 is connected through the L-pipe 61. Multiple thin absorbent cotton ropes 7 are installed at the bottom of the water storage tank 5. A float 8 is installed inside the water storage tank 5. A piston rod 81 is fixed in the float 8 and slidably inserted into the vertical pipe 4. The piston rod 81 has a water outlet hole 811 that is coaxial with the branch pipes 3.

[0030] Reference Figures 1-4 After the entire structure is buried in the soil, when the water level in the water tank 5 is low, the float 8 drives the piston rod 81 to descend under the action of gravity, and the outlet 811 and the branch pipe 3 are connected accordingly. Then, water is used to irrigate the soil through the drain hole 21 of the connecting pipe 2. During the irrigation process, after the soil is thoroughly irrigated, the excess water will seep into the water collection hopper 6 under the action of gravity, and then flow back into the water tank 5 through the L pipe 61. When the rate of return is greater than the rate of water absorption of the thin absorbent cotton rope 7, the water level in the water tank 5 rises, supporting the piston rod 81 upward and causing the outlet 811 to rise. At this time, the piston rod 81 blocks the branch pipe 3, which can realize the automatic closure of the branch pipe 3. When the thin absorbent cotton rope 7 gradually absorbs water to wet the soil, the water level in the water tank 5 drops, the float 8 and the piston rod 81 descend, and the outlet 811 is aligned with the branch pipe 3, which can then be reopened.

[0031] Guide rods 52 are symmetrically fixed inside the water storage tank 5, and guide holes 82 adapted to the guide rods 52 are symmetrically opened on the float 8.

[0032] Reference Figures 2-3 Through the cooperation of guide rod 52 and guide hole 82, when the float 8 is a cylindrical structure, it can guide the float 8 when it floats up and down, so as to avoid the water outlet 811 from being misaligned with the branch pipe 3.

[0033] A limiting plate 53 is fixed on the guide rod 52. The limiting plate 53 is larger than the inner diameter of the guide hole 82. The limiting plate 53 is placed at the upper end of the connection between the L pipe 61 and the water storage tank 5. The water storage tank 5 is placed in the area below the limiting plate 53 to form a sedimentation tank 51.

[0034] Reference Figure 2 and Figure 3 When the lower surface of the float 8 abuts against the limiting plate 53, the outlet hole 811 corresponds to the branch pipe 3, and the lower end opening of the L pipe 61 is placed below the float 8, while a sedimentation tank 51 is formed below to facilitate the sedimentation of sludge.

[0035] The water hopper 6 is an inverted frustum-shaped structure.

[0036] Reference Figure 2 The water collection hopper 6, with its inverted frustum-shaped structure, facilitates the centralized recycling of water.

[0037] A filter plate 62 is fixed to the upper opening of the water collection hopper 6, and a filter cotton 63 is fixed to the lower surface of the filter plate 62.

[0038] Reference Figure 2 Large particles are intercepted by the filter plate 62, and small particles are intercepted by the filter cotton 63, thus preventing the L-tube 61 from becoming clogged.

[0039] Working principle: After the entire unit is buried in the soil, when the water level in the water tank 5 is low, the float 8 drives the piston rod 81 to descend under the action of gravity. The lower edge of the float 8 abuts against the limiting plate 53. The water outlet 811 and the branch pipe 3 are connected accordingly. At this time, the water supply pipe 1 can be transported through the branch pipe 3, through the water outlet 811, to the connecting pipe 2, and then flow out through the drain hole 21. After the soil is thoroughly watered, the water will be filtered by the filter plate 62 and the filter cotton 63, and flow into the water tank 5 through the L pipe 61. When the water level in the water tank 5 rises, the float 8 will drive the piston rod 81 to rise. When the piston rod 81 blocks the branch pipe 3, the connecting pipe 2 will be automatically closed. At the same time, as the water in the soil gradually evaporates, the thin absorbent cotton rope 7 absorbs the water in the water tank 5, causing the water level to drop. The float 8 drives the piston rod 81 to descend and rest on the limiting plate 53, which can then be reopened.
