Description

Technical Field

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

[0002] Drip irrigation is to use plastic pipes to send water to the roots of crops through orifices or drippers on the capillary for local irrigation. Drip irrigation is the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 95%.

[0003] The drip irrigation pipe is laid on the outdoor land. Due to different climates outdoors, there will be strong winds or rain, which will blow the drip irrigation pipe, resulting in the deviation of the drip irrigation pipe and the deviation of the water dripping position of the dripper, making it impossible to accurately drip the water source on the crops. And due to strong wind weather, the soil may be blown into the drippers of the drip irrigation pipe, which may cause blockage of one or more drippers of the overall drip irrigation device, affecting the subsequent irrigation work.

[0004] Therefore, those skilled in the art provide an underground drip irrigation device to solve the problems raised in the above background art. Content of the Utility Model

[0005] The purpose of the utility model is to provide an underground drip irrigation device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An underground drip irrigation device includes a water bucket, an anti-blocking mechanism and a fixing mechanism. An inlet is opened on the upper end surface of the water bucket, and a filter screen is fixedly connected to the inner wall of the inlet. One side wall of the water bucket is penetrated and connected with a main water pipe. The upper end of the main water pipe is penetrated and connected with a plurality of groups of branch drip irrigation pipes. A one-way valve is arranged at one end of the main water pipe close to the water bucket. Fixing mechanisms are arranged at both the left and right ends of the branch drip irrigation pipes. A plurality of groups of lower water pipes are penetrated and connected to the bottom ends of the branch drip irrigation pipes. The lower water pipes are arranged at equal intervals. A dripper is fixedly connected to the bottom end of the lower water pipe. An anti-blocking mechanism is arranged in the lower water pipe and the dripper.

[0008] As a further scheme of the utility model: Adjusting blocks are arranged at both the left and right ends of the branch drip irrigation pipes. Rotating blocks are rotatably connected to one side walls of the adjusting blocks. Transmission rods are fixedly connected to the ends of the rotating blocks close to the adjusting blocks, and after passing through the adjusting blocks, the transmission rods are fixedly connected with first bevel gears.

[0009] As a further solution of the present utility model: The bottom ends of the first bevel gears are all movably connected to the second bevel gears, the second bevel gears are all rotatably connected to the inner wall of the adjusting block, the bottom ends of the second bevel gears are all fixedly connected to the bidirectional lead screws, the bottom ends of the bidirectional lead screws are all rotatably connected to the inner wall of the adjusting block, both sides of the bidirectional lead screws are threadedly connected with threaded sleeves, one ends of the threaded sleeves close to the branch drip irrigation pipes are all fixedly connected with mounting sleeves, the two groups of mounting sleeves and the branch drip irrigation pipes are correspondingly arranged and abutted against each other, and sliding grooves are respectively formed in the inner walls of the adjusting blocks, and sliders are respectively slidably connected between the threaded sleeves and the adjacent sliding grooves, and the sliders are slidably clamped with the sliding grooves.

[0010] As a further solution of the present utility model: Ball grooves are respectively formed in the sewer pipes, floating balls are movably connected in the ball grooves, connecting rods are fixedly connected to the bottom ends of the floating balls, connecting plates are fixedly connected to the bottom ends of the connecting rods, multiple top blocks are fixedly connected to the bottom ends of the connecting plates, multiple water outlet holes are respectively formed in the inner bottom ends of the drip irrigation heads and are correspondingly arranged with the top blocks and the water outlet holes are vertically arranged with the adjacent top blocks, and the connecting plates and the top blocks are both located inside the drip irrigation heads.

[0011] As a further solution of the present utility model: The first bevel gears are all vertically arranged with the second bevel gears, and the first bevel gears are all meshed with the second bevel gears.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Due to the provision of the fixing mechanism, by fixing the branch drip irrigation pipes in the soil, it effectively prevents the pipes from shifting due to wind and rain, ensuring the stable operation of the drip irrigation device, contributing to maintaining the uniformity and efficiency of irrigation. Inserting the grounding conical heads into the soil helps improve the anti-interference ability of the drip irrigation device, especially in bad weather conditions, and the fixing mechanism can be disassembled, and each fixing mechanism can be adjusted to different degrees according to the terrain of the current position; Due to the provision of the anti-blocking mechanism, it can automatically control the water flow, adjust the opening and closing of the drip irrigation holes according to the position of the floating ball in the water level, without manual intervention. When the floating ball rises, the top block disengages from the water outlet hole, preventing the drip irrigation head from being blocked by soil and impurities when not working. When the stop block resets, it can also eject the impurities in the water outlet hole to keep the drip irrigation device unobstructed. The water flowing out through the gap can accurately drip to the roots of the crops, improving the water utilization efficiency, reducing waste, and also preventing excessive drip irrigation of the water flow through the control mechanism of the floating ball, ensuring that the irrigation amount meets the actual needs of the crops.

[0023] Example 2

[0024] Refer to Figure 1 、 2 、3. This embodiment is based on the previous embodiment. The difference from the previous embodiment is that adjusting blocks 8 are provided at both the left and right ends of the branch drip irrigation pipe 6. Rotating blocks 10 are rotatably connected to the side walls of one ends of the adjusting blocks 8. Transmission rods 11 are fixedly connected to the ends of the rotating blocks 10 close to the adjusting blocks 8. After passing through the adjusting blocks 8, the transmission rods 11 are fixedly connected to first bevel gears 12. Second bevel gears 13 are movably connected to the bottoms of the first bevel gears 12. The second bevel gears 13 are rotatably connected to the inner walls of the adjusting blocks 8. Bidirectional lead screws 14 are fixedly connected to the bottoms of the second bevel gears 13. The bottoms of the bidirectional lead screws 14 are rotatably connected to the inner walls of the adjusting blocks 8. Threaded sleeves 15 are threadedly connected to both sides of the bidirectional lead screws 14. Mounting sleeves 7 are fixedly connected to the ends of the threaded sleeves 15 close to the branch drip irrigation pipe 6. The two groups of mounting sleeves 7 are correspondingly arranged and abutted against the branch drip irrigation pipe 6. Sliding grooves 17 are formed in the inner walls of the adjusting blocks 8. Sliders 16 are slidably connected between the threaded sleeves 15 and the adjacent sliding grooves 17. The sliders 16 are slidably clamped with the sliding grooves 17. The first bevel gears 12 are perpendicular to the second bevel gears 13. The first bevel gears 12 are meshed with the second bevel gears 13;

[0025] Place the two groups of mounting sleeves 7 on the upper and lower sides of the branch drip irrigation pipe 6. Shake the rotating blocks 10. The rotating blocks 10 drive the transmission rods 11 to rotate. The transmission rods 11 drive the first bevel gears 12 to rotate. The first bevel gears 12 drive the second bevel gears 13 to rotate. The second bevel gears 13 drive the bidirectional lead screws 14 to rotate. The bidirectional lead screws 14 can drive the threaded sleeves 15 on the left and right sides to move towards one end of the branch drip irrigation pipe 6 at the same time. The branch drip irrigation pipe 6 is fixed through the mounting sleeves 7. When the threaded sleeves 15 move, the sliders 16 assist in sliding in the sliding grooves 17;

[0026] After fixing, insert the grounding conical head 9 into the soil, so as to prevent the branch drip irrigation pipe 6 from running off track and being offset by strong winds and rain.

[0027] Example 3

[0028] Refer to Figure 1 、 2 、4, 5. This embodiment is based on the previous embodiment. The difference from the previous embodiment is that ball grooves 25 are formed in the sewer pipes 18. Floating balls 20 are movably connected in the ball grooves 25. Connecting rods 21 are fixedly connected to the bottoms of the floating balls 20. Connecting plates 22 are fixedly connected to the bottoms of the connecting rods 21. Multiple top blocks 23 are fixedly connected to the bottoms of the connecting plates 22. Multiple water outlet holes 24 are formed in the bottoms of the drip irrigation heads 19 and are correspondingly arranged with the top blocks 23. The water outlet holes 24 are perpendicular to the adjacent top blocks 23. The connecting plates 22 and the top blocks 23 are both located inside the drip irrigation heads 19;

[0029] Before the water enters the water bucket 1, it will be filtered through the filter screen 3 in the water inlet 2 to prevent impurities from clogging in the main water pipe 4 and the branch drip irrigation pipes 6.

[0030] Start the one-way valve 5. The water in the water bucket 1 flows into the branch drip irrigation pipes 6 through the main water pipe 4 respectively. When the water flows into the sewer pipe 18, due to the buoyancy of the water flow, the float ball 20 floats up under the influence of the buoyancy, which can drive the connecting rod 21 and the connecting plate 22 to move upward. The top block 23 in the connecting plate 22 is located in the sewer hole 24 before floating. After floating, the top block 23 disengages from the sewer hole 24. The float ball 20 floats up in the ball groove 25, thereby generating a gap. The water will flow out through the gap and through the sewer hole 24 to drip-irrigate the crops at the bottom. When there is no water, the float ball 20 naturally falls, and the connecting rod 21, the connecting plate 22 and the top block 23 are reset to block the sewer hole 24, thus preventing the drip irrigation head 19 from being clogged by soil and impurities when not working. And at the moment when the stop block is reset, the impurities in the sewer hole 24 are pushed out.
