[0023] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0024] As Figures 1-4 shown, the integrated water and fertilizer irrigation device provided by the embodiment of the present utility model includes a water inlet pipe 1, a shunt pipe 2 and an irrigation pipe 8. A mixing part 6 and a filtering part 7 are provided between the water inlet pipe 1 and the irrigation pipe 8. The filtering part 7 includes a filter pipe 10, a first filter screen 12 and a second filter screen 13. An installation frame 11 is provided on the upper side of the filter pipe 10. The installation frame 11 is communicated with the filter pipe 10. A mounting rack 14 is slidably installed in the installation frame 11. The first filter screen 12 and the second filter screen 13 are both provided on one side of the mounting rack 14, and both the first filter screen 12 and the second filter screen 13 are located in the filter pipe 10. A sealing cover 17 is provided on the upper side of the installation frame 11. A fixing mechanism 16 is provided between the sealing cover 17 and the installation frame 11.

[0025] Specifically, in this embodiment, the irrigation water and the fertilizer water enter the filtering part 7 after being mixed by the mixing part 6. The first filter screen 12 and the second filter screen 13 in the filtering part 7 can double-filter the irrigation water and the fertilizer water, improving the filtering effect on the irrigation water and the fertilizer water. Among them, the first filter screen 12 is located on the front side of the second filter screen 13, and the filter holes of the second filter screen 13 are smaller than those of the first filter screen 12. When it is necessary to clean and filter the first filter screen 12 and the second filter screen 13, by releasing the fixation of the fixing mechanism 16 and pulling up the sealing cover 17, the sealing cover 17 is separated from the mounting frame 11. Then, pull up the mounting rack 14, so that the mounting rack 14 drives the first filter screen 12 and the second filter screen 13 to move upward. Thus, the disassembly of the first filter screen 12 and the second filter screen 13 can be completed. After the user finishes cleaning, by operating the above steps in reverse, the first filter screen 12 and the second filter screen 13 are installed back into the filter pipe 10, and the sealing cover 17 is fixed on the mounting frame 11 through the fixing mechanism 16. Among them, a sealing rubber strip is provided between the sealing cover 17 and the mounting frame 11, and a sealing rubber strip is also provided on the periphery of the mounting rack 14. And a handle is provided on the upper side of the periphery of the mounting rack 14, which can facilitate the user to pull the mounting rack 14. After the sealing cover 17 is fixed to the mounting frame 11, the sealing cover 17 presses the upper side of the mounting rack 14.

[0026] For the integrated water and fertilizer irrigation device provided by the present utility model, the fixing mechanism 16 includes a fixing shell 18, a plug board 21 and a U-shaped clamping board 22. The fixing shell 18 is fixedly installed on one side of the mounting frame 11. The plug board 21 is fixedly installed on one side of the sealing cover 17. One end of the plug board 21 is movably inserted into the fixing shell 18. A mounting cavity 20 is provided in the fixing shell 18. The U-shaped clamping board 22 is slidably installed in the mounting cavity 20. One end of the U-shaped clamping board 22 corresponds to the plug board 21. A spring 23 is provided between the U-shaped clamping board 22 and the mounting cavity 20. A limiting sliding groove 25 is opened on one side of the fixing shell 18. The limiting sliding groove 25 is communicated with the mounting cavity 20. A pressing block 24 is slidably installed in the limiting sliding groove 25. The pressing block 24 is fixedly connected to the other end of the U-shaped clamping board 22.

[0027] In another embodiment provided by the present utility model, when it is necessary to fix the sealing cover 17 on the mounting frame 11, the sealing cover 17 is covered on the mounting frame 11. At the same time, when the insertion plate 21 on one side of the sealing cover 17 is inserted into the upper side of the fixed shell 18, one end of the insertion plate 21 is provided with a triangular clamping block, and one side of one end of the U-shaped clamping plate 22 is provided with a chamfered surface. Then, when the triangular clamping block contacts one end of the U-shaped clamping plate 22, the inclined surface on one side of the triangular clamping block fits with the chamfered surface on one side of one end of the U-shaped clamping plate 22. Then, by pushing the sealing cover 17 and the insertion plate 21, the insertion plate 21 drives the triangular clamping block to provide a squeezing force to the U-shaped clamping plate 22. The U-shaped clamping plate 22 will retract into the installation cavity 20 under the squeezing force, so that the insertion plate 21 can drive the triangular clamping block to be completely inserted into the fixed shell 18. When the insertion plate 21 and the triangular clamping block are completely inserted into the fixed shell 18, since the thickness of the insertion plate 21 is less than the thickness of the triangular clamping block, when one end of the U-shaped clamping plate 22 corresponds to the insertion plate 21, the U-shaped clamping plate 22 can extend out of the installation cavity 20 by the elastic force of the spring 23, so that the U-shaped clamping plate 22 can fit with the insertion plate 21. When the U-shaped clamping plate 22 can fit with the insertion plate 21, one side of the U-shaped clamping plate 22 will clamp one side of the triangular clamping block, thereby being able to quickly fix the sealing cover 17, so that the sealing cover 17 can be tightly covered on the mounting frame 11. When it is necessary to open the sealing cover 17, by pressing the pressing block 24, the pressing block 24 drives the U-shaped clamping plate 22 to retract into the installation cavity 20, releasing the clamping of the triangular clamping block. Then, the insertion plate 21 and the triangular clamping block are pulled out of the fixed shell 18, and the sealing cover 17 can be opened. Among them, a guide groove is provided on one side of the U-shaped clamping plate 22, and a guide post is provided on one side of the inner wall of the installation cavity 20. The guide groove is slidably connected with the guide post, and the guide groove and the guide post are used to improve the stability and smoothness when the U-shaped clamping plate 22 extends out of and retracts into the installation cavity 20.

[0028] The integrated water and fertilizer irrigation device provided by the present utility model, the mixing part 6 includes a mixing pipe 27 and a spiral plate 26. The spiral plate 26 is arranged inside the mixing pipe 27. One end of the mixing pipe 27 is fixedly connected with one end of the filtering pipe 10. The water inlet pipe 1 includes a connecting pipe 4 and a contraction throat pipe 5. One end of the contraction throat pipe 5 is fixedly connected with one end of the connecting pipe 4. The other end of the contraction throat pipe 5 is fixedly connected with one end of the mixing pipe 27. The shunt pipe 2 is arranged on one side of the contraction throat pipe 5. A valve 3 is arranged in the middle section of the shunt pipe 2. One end of the irrigation pipe 8 is fixedly connected with one end of the filtering pipe 10. A plurality of water outlets 9 are arranged on one side of the irrigation pipe 8.

[0029] In another embodiment provided by the present utility model, the connecting pipe 4 is connected to an external water pipe, and the shunt pipe 2 is connected to the fertilizer tank. Irrigation water flows in from the connecting pipe 4. When the control valve 8 is opened and the irrigation water flows through the contraction throat 5, since the pipe diameter at the contraction throat 5 decreases, the flow velocity of the water increases at the contraction throat 5, increasing the suction force at the shunt pipe 2. As a result, the fertilizer water enters the contraction throat 5 through the shunt pipe 2. Then, when the irrigation water and the fertilizer water enter the mixing part 6, the spiral plate 26 causes the irrigation water and the fertilizer water to flow spirally, and can increase the mixing time of the irrigation water and the fertilizer water, enabling the irrigation water and the fertilizer water to be fully mixed. After being filtered by the filtering part 7, the mixed irrigation water and fertilizer water flow into the irrigation pipe 8, and then, the water outlet head 9 on one side of the irrigation pipe 8 is used to perform integrated water and fertilizer irrigation on the crops.

[0030] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
