[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] This invention provides a multi-functional sprinkler irrigation device integrating water and fertilizer, such as... Figures 1-5 As shown, the system includes a trolley 1 and a spraying assembly and a water-fertilizer assembly mounted thereon. The water-fertilizer assembly supplies water and fertilizer to the spraying assembly. In this embodiment, two sets of spraying assemblies are preferably provided and located on both sides of the water-fertilizer assembly. The spraying assembly includes:

[0036] The second turntable 22, which is rotatably mounted on the trolley 1, can be rotatably mounted via bearings. The trolley 1 is fixed with a second stepper motor 26 for driving the second turntable 22 to rotate. The output shaft of the second stepper motor 26 can be welded and fixed to the center of the second turntable 22.

[0037] A connecting plate 25 is vertically disposed on the outer side of the second turntable 22. The connecting plate 25 is fixed on the slide block 21. The slide block 21 is slidably mounted on the trolley 1. A sliding groove for the slide block 21 to slide and connect can be opened on the trolley 1. A second pin 29 is eccentrically fixed on the end face of the second turntable 22 near the connecting plate 25. It can be fixed by welding. A second movable groove is opened on the connecting plate 25 along its length direction for the second pin 29 to pass through and move.

[0038] A mounting plate 23 is vertically disposed on the outside of the connecting plate 25. Multiple nozzles 24 are installed on the mounting plate 23 at intervals. They can be installed by screws. The bottom end of the mounting plate 23 is hinged to the slide 21.

[0039] A rotating sleeve 27, which is rotatably connected to the end of the second pin 29 away from the second turntable 22, can be rotatably installed via a bearing. A connecting rod 28 is connected between the rotating sleeve 27 and the mounting plate 23. The two ends of the connecting rod 28 are respectively hinged to the rotating sleeve 27 and the mounting plate 23.

[0040] During operation, the second stepper motor 26 is started to drive the second turntable 22 to rotate. The second turntable 22 drives the second pin 29 to rotate. The second pin 29 drives the connecting plate 25 to reciprocate. The connecting plate 25 drives the slide 21 to reciprocate. The slide 21 drives the mounting plate 23 and the nozzle 24 to move back and forth, spraying water and fertilizer over a wide area. At the same time, when the second pin 29 moves, it drives the rotating sleeve 27 to move. The rotating sleeve 27 drives the mounting plate 23 to swing back and forth through the connecting rod 28, further expanding the spraying range and improving the spraying efficiency.

[0041] The outlet of the water and fertilizer component is connected to all nozzles 24 via a liquid supply pipe 2, and a booster pump 3 is installed on the liquid supply pipe 2.

[0042] Specifically, the water and fertilizer component includes:

[0043] A water and fertilizer tank 4 is fixed on the trolley 1. The top of the water and fertilizer tank 4 is equipped with a fertilizer hopper 9. The bottom of the water and fertilizer tank 4 is connected to a liquid supply pipe 2. A door can be installed on the water and fertilizer tank 4, which can be installed by hinges and buckles.

[0044] The mixing component is installed inside the water and fertilizer tank 4;

[0045] Fertilizer and water are added to the water-fertilizer tank 4 through the fertilizer hopper 9. Then, the fertilizer is fully dissolved in the water by the stirring component and mixed evenly to form water-fertilizer. When working, the booster pump 3 is started to draw the water-fertilizer in the water-fertilizer tank 4 into the liquid supply pipe 2 and then spray it out from the nozzle 24.

[0046] Specifically, the stirring assembly includes:

[0047] Net tube 5;

[0048] A grinding roller 7 is coaxially arranged inside the mesh cylinder 5, and the lower part of the grinding roller 7 is frustoconical.

[0049] An installation rod 13 is fixed to the top of the grinding roller 7 and is coaxially arranged therewith. The top of the installation rod 13 extends to the top of the water and fertilizer tank 4. The installation rod 13 is rotatably connected to the top of the water and fertilizer tank 4 so that the installation plate 23 can swing left and right. An outer spiral rod 11 is coaxially inserted inside the installation rod 13. The bottom end of the outer spiral rod 11 passes through the grinding roller 7 and is fixedly connected to the bottom of the mesh cylinder 5. The outer spiral rod 11 is spirally connected to the installation rod 13. An inner spiral groove that spirally engages with the outer spiral rod 11 can be provided on the installation rod 13.

[0050] The first turntable 10, which is rotatably mounted on the top of the water and fertilizer tank 4 and located on the rear side of the mounting rod 13, can be rotatably mounted by bearings and bearing seats. The top of the water and fertilizer tank 4 is fixed with a first stepper motor (not shown in the figure) for driving the first turntable 10 to rotate, which can be fixed by bolts. The output shaft of the first stepper motor can be welded and fixed to the center of the first turntable 10.

[0051] The first pin 12, which is eccentrically fixed to the first turntable 10, can be fixed in an integral manner. The mounting rod 13 has a first movable groove along its length for the first pin 12 to be inserted and moved. A connecting seat is hinged to the first pin 12. The connecting seat is rotatably connected to the top end of the outer spiral rod 11 located in the first movable groove.

[0052] During operation, fertilizer is placed into the mesh cylinder 5, and the first stepper motor is started. The first stepper motor drives the first turntable 10 to rotate, and the first turntable 10 drives the first pin shaft 12 to move. The first pin shaft 12 drives the grinding roller 7 to swing through the mounting rod 13. The grinding roller 7 swings synchronously with the mesh cylinder 5. At the same time, the first pin shaft 12 drives the outer spiral rod 11 to reciprocate relative to the mounting rod 13 in the length direction. The outer spiral rod 11 drives the mesh cylinder 5 to reciprocate relative to the grinding roller 7 in the length direction. Since the outer spiral rod 11 and the mounting rod 13 are spirally connected, the outer spiral rod 11 rotates in both directions. The outer spiral rod 11 drives the mesh cylinder 5 to rotate in both directions. The grinding roller 7 can repeatedly squeeze and grind the fertilizer in the mesh cylinder 5, so that the fertilizer becomes powder and can be fully and quickly dissolved in water, thus speeding up the water-fertilizer preparation speed.

[0053] Preferably, in order to improve the extrusion and grinding effect, protrusions are fixed on the lower inner wall of the mesh cylinder 5 and the lower outer wall of the grinding roller 7, which can be fixed by screws;

[0054] Furthermore, multiple stirring rods are circumferentially hinged to the outer wall of the mesh cylinder 5. When the mesh cylinder 5 rotates, the stirring rods deflect under centrifugal force and gravity, thus fully stirring the water and fertilizer.

[0055] Furthermore, the grinding roller 7 is provided with a fertilizer channel 6. One end of the fertilizer channel 6 is open at the lower part of the grinding roller 7, and the other end of the fertilizer channel 6 is open at the upper part of the grinding roller 7. The upper part of the grinding roller 7 is provided with a feed guide shell that communicates with the fertilizer channel 6. The feed guide shell is connected to the discharge port at the bottom of the fertilizer hopper 9 through a soft material tube 8.

[0056] During operation, the fertilizer in the fertilizer hopper 9 automatically enters the soft material pipe 8 from the discharge port, and then enters the fertilizer channel 6 from the feed guide shell. It falls from the fertilizer channel 6 into the space between the grinding roller 7 and the screen cylinder 5, and is continuously ground by the screen cylinder 5 and the grinding roller 7, and is evenly mixed with water to form water fertilizer.

[0057] Preferably, in order to avoid the fertilizer channel 6 from being blocked by continuous fertilizer feeding, a valve plate 16 is installed on the feed guide shell. The valve plate 16 moves up and down through the feed guide shell. A tension spring 17 is connected between the top of the valve plate 16 and the grinding roller 7. The two ends of the tension spring 17 can be hooked to the valve plate 16 and the grinding roller 7 respectively. The bottom end of the valve plate 16 abuts against the top of the mesh cylinder 5. A through hole 20 is opened on the valve plate 16 for the fertilizer in the feed guide shell to pass through.

[0058] During the reciprocating motion of the mesh cylinder 5, the mesh cylinder 5 pushes the valve plate 16 upward. With the cooperation of the tension spring 17, the valve plate 16 reciprocates, so that the through hole 20 on the valve plate 16 intermittently communicates with the inner cavity of the feed guide shell, so that the fertilizer intermittently enters the fertilizer channel 6, avoiding blockage caused by excessive feeding speed or too much material.

[0059] In specific implementation, in order to prevent the fertilizer channel 6 from being blocked, a piston 14 chamber is provided inside the mounting rod 13 along its length direction. The piston 14 is rotatably mounted on the rod section of the outer spiral rod 11 located in the piston 14 chamber. It can be rotatably mounted through a sealed bearing. The bottom end of the piston 14 chamber is connected to the fertilizer channel 6 through a connecting channel 18. A water suction pipe is connected to the bottom end of the piston 14 chamber. The water suction pipe is connected to the inner cavity of the water and fertilizer tank 4. A one-way valve is installed on both the connecting channel 18 and the water suction pipe.

[0060] It needs to be explained that when the piston 14 moves upward relative to the mounting rod 13, it draws the water and fertilizer in the water and fertilizer tank 4 into the piston 14 chamber through the suction pipe. Then, the piston 14 moves downward relative to the mounting rod 13, and the piston 14 pushes the water and fertilizer in the piston 14 chamber into the fertilizer channel 6 through the connecting channel 18, impacting the fertilizer in the fertilizer channel 6 and preventing blockage.

[0061] In summary, this invention provides a multi-functional sprinkler irrigation device integrating water and fertilizer, the working principle of which is as follows:

[0062] Fertilizer is added to fertilizer hopper 9. The fertilizer in fertilizer hopper 9 automatically enters the soft material pipe 8 from the discharge port, and then enters the fertilizer channel 6 from the feed guide shell. From the fertilizer channel 6, it falls between the grinding roller 7 and the screen cylinder 5. The first stepper motor is started, which drives the first turntable 10 to rotate. The first turntable 10 drives the first pin shaft 12 to move. The first pin shaft 12 drives the grinding roller 7 to swing through the mounting rod 13. The grinding roller 7 and the screen cylinder 5 swing synchronously together. At the same time, the first pin shaft 12 drives the outer spiral rod 11 to reciprocate relative to the mounting rod 13 in the length direction. The outer spiral rod 11 drives the screen cylinder 5 to reciprocate relative to the grinding roller 7 in the length direction. Since the outer spiral rod 11 and the mounting rod 13 are spirally connected, the outer spiral rod 11 rotates in both directions. The outer spiral rod 11 drives the mesh cylinder 5 to rotate in both directions. The grinding roller 7 can repeatedly squeeze and grind the fertilizer in the mesh cylinder 5, turning the fertilizer into powder. After the water and fertilizer are prepared, the booster pump 3 starts, sucking the water and fertilizer in the water and fertilizer tank 4 into the liquid supply pipe 2, and then spraying it out from the nozzle 24. The second stepper motor 26 is started to drive the second turntable 22 to rotate. The second turntable 22 drives the second pin 29 to rotate. The second pin 29 drives the connecting plate 25 to reciprocate. The connecting plate 25 drives the slide 21 to reciprocate. The slide 21 drives the mounting plate 23 and the nozzle 24 to move back and forth, spraying water and fertilizer over a wide area. At the same time, when the second pin 29 moves, it drives the rotating sleeve 27 to move. The rotating sleeve 27 drives the mounting plate 23 to swing back and forth through the connecting rod 28.
