[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 9 The present invention provides a technical solution: including a frame 1, a drive wheel 2 rotatably mounted on the bottom of the frame 1, and a mixing drum 3 fixedly installed on one side of the top of the frame 1;

[0039] The front part of the frame 1 is equipped with a release irrigation mechanism 4, a positioning mechanism 5, a transmission mechanism 6, and a winding auxiliary mechanism 7.

[0040] The irrigation release mechanism 4 includes a conveying pipe 401 connected to the mixing drum 3. A valve body 402 is connected to the conveying pipe 401. The other end of the conveying pipe 401 is rotatably connected to a take-up roller 403. A connecting pipe 404 is provided on the take-up roller 403. One end of the connecting pipe 404 is connected to the conveying pipe 401 through the take-up roller 403, and the other end is connected to a micro-spraying tape pipe 405. The micro-spraying tape pipe 405 is wound up on the take-up roller 403, and the end away from the take-up roller 403 is sealed and connected to an installation head 406.

[0041] The positioning mechanism 5 includes a stand 501 fixedly connected to the front side of the frame 1, a pressure frame 502 slidably connected on the stand 501, and a drive motor 503 fixedly installed on the top of the stand 501. The drive motor 503 drives the pressure frame 502 to slide along the stand 501 through a lead screw.

[0042] A rod 504 is provided on the front side of the upright frame 501. The top of the rod 504 is movably inserted into the pressure frame 502. An installation ring 505 is fixedly connected to the middle of the rod 504. An installation head 406 is fixedly connected to the inner surface of the installation ring 505.

[0043] A support plate 506 is fixedly connected to the bottom of the upright frame 501. A through opening 507 is provided on the support plate 506. Clamping blocks 508 are provided on both sides of the upper part of the through opening 507. The clamping blocks 508 are used to clamp the middle part of the insertion rod 504. An inclined wedge block 509 is fixedly connected to the side of the clamping block 508. The inclined wedge block 509 is slidably connected to the support plate 506, and the ends of the inclined wedge block 509 that are far apart from each other are abutted against a first spring 510. The first spring 510 is movably sleeved on the support plate 506. An extrusion member 511 is fixedly connected to the bottom of the pressure frame 502. The extrusion member 511 abuts against the surface of the inclined wedge block 509.

[0044] In this embodiment, before the water and fertilizer sprinkler irrigation begins, water and fertilizer are injected into the mixing drum 3. Then, the drive wheel 2 is controlled to move the frame 1 to the irrigation site, positioning the insertion rod 504 in the center of the two irrigation points. The drive motor 503 drives the lead screw to rotate, causing the transmission pressure frame 502 to slide downwards towards the support frame 501. During the descent of the pressure frame 502, the insertion rod 504 descends synchronously. After a short time, the bottom of the insertion rod 504 contacts the soil surface. The pressure frame 502 continues to descend, contacting the top of the insertion rod 504, pressing it downwards. The sharp point at the bottom of the insertion rod 504 inserts into the soil. The insertion rod 504 descends through the mounting ring 505. The installation head 406 moves synchronously, and the maximum stroke of the insertion rod 504 into the soil is the distance between the support plate 506 and the ground. Before the support plate 506 contacts the ground, the extrusion piece 511 extrudes the inclined wedge block 509 as the pressure frame 502 descends. The inclined wedge block 509 moves to both sides and away, compressing the first spring 510. The two clamping blocks 508 contact the clamping of the insertion rod 504. At this time, the lower part of the insertion rod 504 is inserted into the soil, completing the positioning and fixing operation of the installation head 406. The insertion rod 504 is released. Subsequently, the pressure frame 502 remains in the bottoming state, and the drive wheel 2 drives the frame 1 to move away from the insertion rod 504.

[0045] In this embodiment, after the micro-sprinkler hose 405 is fully released, the frame 1 stops moving, the control valve body 402 opens, and the water and fertilizer in the mixing drum 3 enter the winding roller 403 through the transmission pipe. Under the conduction of the connecting pipe 404, the water and fertilizer are introduced into the micro-sprinkler hose 405 and sprayed outward for irrigation.

[0046] The transmission mechanism 6 includes a first pulley assembly 601 connected to one of the drive wheels 2 located at the front of the frame 1. The top of the first pulley assembly 601 is connected to a rotating shaft 602. The other end of the rotating shaft 602 is fixedly connected to one end of a bevel gear assembly 603. The bevel gear assembly 603 has two parts that mesh with each other. One part is fixedly connected to the rotating shaft 602, and the other part is rotatably connected to the frame 1. The top of the bevel gear assembly 603 is fixedly connected to a lower pair of shafts 604.

[0047] A top plate 605 is fixedly connected to the back of the upright frame 501. A rotating shaft 606 is rotatably connected to the top plate 605. An upper pair of shafts 607 is slidably connected to the lower part of the rotating shaft 606. A second spring 608 is movably sleeved on the bottom of the upper pair of shafts 607. The top of the second spring 608 abuts against the upper pair of shafts 607.

[0048] A lower pressure frame 609 is slidably connected to the top plate 605. The bottom of the lower pressure frame 609 abuts against the upper shaft member 607, and the top of the lower pressure frame 609 abuts against the back of the pressure frame 502. The upper shaft member 607 and the lower shaft member 604 are movably engaged.

[0049] The top of the rotating shaft 606 is connected to a second pulley group 610, the end of the second pulley group 610 is connected to a vertical shaft 611, the vertical shaft 611 is rotatably connected to the frame 1, the top of the vertical shaft 611 is connected to a third pulley group 612, and the third pulley group 612 is drively connected to the mixing shaft of the mixing drum 3.

[0050] A drive gear 613 is fixedly connected to the bottom of the vertical shaft 611, and a conversion gear 614 meshes with the side of the drive gear 613. The conversion gear 614 is fixedly connected to the bottom of the take-up roller 403.

[0051] In this embodiment, during the positioning operation of the insertion rod 504, when the pressure frame 502 presses down to the bottom, it presses the lower pressure bracket 609 downward, causing the upper shaft member 607 to be squeezed and slide downward, compressing the second spring 608, causing the upper shaft member 607 to engage with the lower shaft member 604, and this state is maintained. After the two shaft members are engaged, the drive wheel 2 runs, driving the frame 1 to move away from the insertion rod 504. The drive wheel 2 drives the vertical shaft 611 to rotate through the first pulley group 601, the bevel gear group 603, and the second pulley group 610. The bottom of the vertical shaft 611 drives the take-up roller 403 to rotate through the drive gear 613 and the conversion gear 614. The take-up roller 403 refers to... Figure 1 The device rotates counterclockwise as shown. During this process, the mounting head 406 pulls the end of the micro-spraying pipe 405, which, in conjunction with the take-up roller 403, gradually releases the micro-spraying pipe 405. The top of the vertical shaft 611 drives the mixing shaft of the mixing drum 3 to rotate through the third pulley group 612. When the frame 1 moves to release the micro-spraying pipe 405, the water and fertilizer are stirred to prevent the fertilizer components from settling to the bottom and causing uneven distribution of fertilizer components.

[0052] In this embodiment, the transmission ratio between the first pulley group 601, the second pulley group 610, the drive gear 613 and the conversion gear 614 is one to one, ensuring that the micro-spray hose 405 will not get stuck during the walking and releasing process.

[0053] A ring 701 is fixedly connected to the top surface of the take-up roller 403. The ring 701 and the take-up roller 403 are coaxial. Several paddles 702 are arranged around the outer surface of the ring 701.

[0054] A mounting frame 703 is provided on the front side of the take-up roller 403. Squeeze rollers 704 are slidably connected to both sides of the mounting frame 703. The bottom of the squeeze rollers 704 is slidably connected to the frame 1. A trigger spring 705 is movably sleeved on the mounting frame 703 and a pusher 706 is slidably connected to the top of the mounting frame 703. Rubber wheels 707 are rotatably connected to both sides of the pusher 706. The rubber wheels 707 are in frictional contact with the top of the squeeze rollers 704.

[0055] A mounting base 708 is fixedly mounted on the other side of the mounting bracket 703. A slide rod 709 is slidably connected inside the mounting base 708. A guide wheel 710 is rotatably connected to one end of the slide rod 709 near the take-up roller 403. The middle part of the slide rod 709 passes through the mounting base 708 and is fixedly connected to a slide block 711. An extension spring 712 that is movably sleeved on the mounting base 708 is abutted against the side of the slide block 711 away from the guide wheel 710.

[0056] A pull-back plate 713 is fixedly connected to the end of the slide rod 709 away from the guide wheel 710, and the pull-back plate 713 abuts against the middle of the push frame 706;

[0057] In this embodiment, after irrigation is completed, the drive wheel 2 drives the frame 1 to approach the insertion rod 504. When the drive wheel 2 rotates in the reverse direction, it drives the take-up roller 403 to rotate in the reverse direction, so that during the return process, the micro-spraying tape 405 is automatically wound up. Previously, when the take-up roller 403 releases the micro-spraying tape 405, the paddle 702 on the outside of the ring 701 will continuously push the guide wheel 710 when it makes a circular motion. The guide wheel 710 drives the slide rod 709 to slide towards the upright frame 501. During the process, the slide block 711 moves synchronously and compresses the extension spring 712. After each paddle 702 passes the guide wheel 710, the slide block 711 drives the guide wheel 710 to automatically return to its original position under the action of the extension spring 712, and is pushed again by another paddle 702, so that the guide wheel 710 performs a return operation after being pushed. When the take-up roller 403 winds up the micro-spraying tape 405, the paddle 702 moves with the take-up roller 403. In reverse rotation, the lever 702 pulls the guide wheel 710 to move horizontally. During this process, the other end of the slide rod 709 drives the pull plate 713 to contact the push frame 706. The pull plate 713 pulls the push frame 706, and the rubber wheels 707 on both sides disconnect from the extrusion rollers 704. Under the action of the trigger spring 705, the two extrusion rollers 704 quickly approach each other, reducing the space between the micro-spray tubes 405. The outer surface of the micro-spray tubes 405, which expand outward under water pressure, contacts the extrusion rollers 704. During the winding process of the micro-spray tubes 405, the two extrusion rollers 704 perform a water-squeezing operation to squeeze out excess water and fertilizer from the micro-spray tubes 405. The middle part of the two extrusion rollers 704 rotates as the micro-spray tubes 405 move to prevent friction from damaging the micro-spray tubes 405. When the frame 1 approaches the insertion rod 504, the automatic winding operation of the micro-spray tubes 405 is completed.

[0058] The method of use and advantages of this invention: The working process of this water and fertilizer irrigation device for smart agriculture is as follows:

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown:

[0060] S1: Before the sprinkler irrigation begins, water and fertilizer are injected into the mixing drum 3. The sharp end of the bottom of the insertion rod 504 is inserted into the soil. The insertion rod 504 descends and the installation head 406 is lowered through the installation ring 505. At the same time, the insertion rod 504 is removed from the frame. At this time, the lower part of the insertion rod 504 is inserted into the soil, completing the positioning and fixing operation of the installation head 406.

[0061] S2: When the pressure frame 502 is pressed down to the bottom, the upper shaft 607 is squeezed and slides downward, causing the upper shaft 607 to engage with the lower shaft 604. The drive wheel 2 runs and moves away. The drive wheel 3 drives the vertical shaft 611 to rotate through the first pulley group 601, the bevel gear group 603, and the second pulley group 610. The winding roller 403 cooperates to gradually release the micro-spraying pipe 405. The mixing shaft of the mixing drum 3 rotates to stir and mix the water and fertilizer.

[0062] S3: After the micro-sprinkler hose 405 is fully released, water and fertilizer are introduced into the micro-sprinkler hose 405 and sprayed outward for irrigation;

[0063] S4: After the water and fertilizer irrigation is completed, the drive wheel 2 drives the frame 1 to approach the insertion rod 504. The micro-spraying hose 405 is automatically wound up. During the process, the paddle 702 rotates in the opposite direction with the winding roller 403. The pull plate 713 pulls the push frame 706. The two squeezing rollers 704 quickly approach each other under the action of the trigger spring 705. The two squeezing rollers 704 perform water squeezing operation on the micro-spraying hose 405 to squeeze out the excess water and fertilizer in the micro-spraying hose 405.
