Description

Technical Field

[0001] The invention relates to the field of agricultural planting, and more specifically to a rice water-fertilizer integrated irrigation device. Background Art

[0002] The integrated water-fertilizer irrigation device for rice is a modern agricultural technology equipment integrating irrigation and fertilization.

[0003] The water-fertilizer integrated irrigation device in the prior art combines irrigation water with fertilizer solution through an integrated system. For example, a water-fertilizer integrated irrigation device disclosed in the prior art patent (publication number / announcement number: CN116569725A) controls the peristaltic pump and multiple solenoid valves to work through a control cabinet, pumps the fertilizer solution into a fertilizer mixing tank and mixes it with irrigation water, and then discharges the fertilizer water in the fertilizer mixing tank and implements irrigation through drip irrigation or sprinkler irrigation. This method can realize automatic irrigation, but the construction cost of the device is high. At the same time, as the use time increases, the water pipes and nozzles in the irrigation system will frequently become clogged, resulting in some areas being unable to irrigate with water, and later maintenance and repair are more troublesome;

[0004] At the same time, a walkable integrated water-fertilizer irrigation device has emerged in the prior art. For example, an existing patent (publication number / announcement number: CN116349586A) discloses an integrated water-fertilizer irrigation system. The device does not need to lay pipes and sprinklers over a large area like the above-mentioned irrigation system. The mixing unit of liquid fertilizer and irrigation water and the irrigation unit are designed to be movable, and the integrated water-fertilizer irrigation of crops is achieved by moving the driving device. Even if the sprinkler unit is blocked, it can be discovered and maintained in time. The device has a simple structure, and the construction cost and subsequent maintenance cost are low.

[0005] However, this type of movable integrated irrigation device usually needs to be equipped with a water tank for storing irrigation water and a fertilizer tank for storing a mixture of irrigation water and fertilizer. Since the irrigation water in the water tank and the fertilizer liquid in the fertilizer tank are heavy, it will be difficult to move the entire device, especially when the irrigation position needs to be changed frequently. At the same time, due to the presence of gullies in the fields and the soft soil, the irrigation device is prone to structural instability and tipping over when moving in the field, and the flexibility and operability of the device will be affected to a certain extent. Summary of the invention

[0006] In view of the problems existing in the prior art, the object of the present invention is to provide a rice water-fertilizer integrated irrigation device.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0013] Furthermore, a guide vane is fixedly connected to the inner wall of the conical diffusion end, which is used to prevent the vortex of the fluid in the shell four from driving the fluid in the shell three to form a vortex and to make the fluid flow even.

[0014] Furthermore, the static mixing element includes a shell body 2 fixedly connected to a lower end of the shell body, an inner barrel body rotatably connected to the inside of the shell body 2, limiting holes provided in the shell body 2 and the inner barrel body, limiting pins inserted in the limiting holes, a mixing element movably connected to the inner wall of the inner barrel body, a connecting seat fixedly connected to the lower end of the mixing element, and a limiting ring screwed to the lower end of the inner wall of the shell body 2 for limiting the mixing element.

[0016] Furthermore, a rod body is fixedly connected to the outer surface of the rotating rod, and an elastic paddle is fixedly connected to the outer surface of the rod. A flange for contacting the elastic paddle to cause the rod body and the rotating rod to vibrate is integrally formed on the four inner walls of the shell. A slide groove is opened on the inner wall of the inner barrel body, and a slide bar is slidably connected in the slide groove. One side of the slide bar is fixedly connected to the outer surface of the mixing element.

[0017] Furthermore, a pipeline positioning unit is also connected to the upper end of the frame, and the pipeline positioning unit includes two slide grooves opened inside the frame, a support bracket with one end fixed to the outer surface of the rotary joint, two movable grooves opened inside the support bracket, a slider movably connected inside the movable groove and with the lower end slidingly connected to the two slide grooves, a protrusion and multiple positioning blocks fixed to the upper end of the support bracket, a rubber gasket fixed inside the positioning block, an arc-shaped support plate movably connected inside one of the positioning blocks and with one end fixed to one side of the slider, and a step integrally formed on the inner wall of the second slide groove.

[0018] Furthermore, a connecting unit is fixedly connected to the outer surface of the frame, and the connecting unit includes connecting plates fixedly connected to the upper and lower ends of the frame, pin holes opened inside the connecting plates, two side plates fixedly connected to both sides of the connecting plates, and positioning holes opened inside the side plates. The irrigation unit includes a fixed frame fixedly connected to the outer surface of one side of the support plate, a pump body fixedly connected to the fixed frame and with its input end connected to the output end of the water-fertilizer mixing assembly, and a sprinkler assembly fixedly connected to one side of the support plate and connected to the output end of the pump body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This solution is provided with a water-fertilizer mixing assembly. The static mixer can directly mix the irrigation water in the rotary joint with the liquid fertilizer in the fertilizer pump quickly and evenly, ensuring that the fertilizer is fully dispersed and evenly distributed in the irrigation water, thereby improving the efficiency and accuracy of fertilization. In this way, the rotary joint is directly connected to the irrigation water supply pipe, and water-fertilizer integrated irrigation can be directly achieved through real-time water supply. The device does not need to carry a water tank and a mixing box, which improves the flexibility of the device and the stability of the device in the field. At the same time, before the liquid fertilizer is discharged from the drainage hole and enters the static mixer, it can be premixed with the irrigation water entering the shell one, thereby improving the mixing uniformity and reducing the mixing dead zone.

[0021] (2) This solution provides a speed increasing assembly downstream of the static mixer, and drives the propeller to rotate through a motor, which can not only increase the flow rate of the fluid inside the water-fertilizer mixing assembly, but also enhance the friction and shear force between the fluids, mix different fluids together faster and more evenly, shorten the time required for mixing, and at the same time reduce some of the pressure loss caused by the static mixer, improve the uneven mixing that may exist after the fluid passes through the static mixer, and improve the fluid mixing processing capacity of the water-fertilizer mixing assembly. The increase in flow rate can help reduce the precipitation and scaling inside the water-fertilizer mixing assembly and reduce the risk of blockage.

[0022] (3) In this solution, an isolation module is provided between the static mixer and the speed increasing component. When the fluid passes through the tapered convergent end of the isolation module, the flow velocity gradually increases, thereby reducing the flow cross-sectional area. This not only cooperates with the speed increasing component to increase the flow velocity, but also reduces the mutual interference of the fluid between the static mixer and the speed increasing component. At the same time, the guide vanes provided on the inner wall of the tapered diffusion end can help guide the fluid to flow along the expected path, making the flow direction of the fluid more stable and consistent, reducing the chaos of the fluid flow and the formation of vortices, and also increasing the kinetic energy of the fluid when passing through the diffusion end, thereby increasing the speed and pressure of the fluid. The guide vanes cooperate with the tapered convergent end to effectively solve the problem of mutual interference between the static mixer and the speed increasing component when used simultaneously.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 12 , a rice water-fertilizer integrated irrigation device, comprising a frame 1, a support plate 3 fixedly connected to the lower end of the frame 1, and a wheel body 4 rotatably connected to one side of the support plate 3, wherein a water-fertilizer mixing unit 5 is arranged at the upper end of the frame 1, and the water-fertilizer mixing unit 5 is used to transport irrigation water and liquid fertilizer into a water-fertilizer mixing component 6, and the water-fertilizer mixing component 6 is used to directly mix the liquid fertilizer with the irrigation water;

[0039] The water-fertilizer mixing assembly 6 includes a shell 61 fixedly connected to the lower end of the frame 1, a serpentine tube 611 fixedly connected to the inside of the shell 61, a drainage hole 612 provided inside the serpentine tube 611 for dispersing and discharging the liquid fertilizer so as to premix the liquid fertilizer with the irrigation water, and a static mixer 62 fixedly connected to the lower end of the shell 61 for generating a turbulent effect to promote the mixing and dissolution of the liquid fertilizer and the irrigation water;

[0040] The water-fertilizer mixing unit 5 includes a liquid fertilizer storage barrel 51 fixedly connected to the upper end of the frame 1, a rotary joint 52 rotatably connected to the upper end of the frame 1 for conveying irrigation water, a fertilizer pump 53 fixedly connected to the inside of the frame 1 and having its input end connected to the output port of the liquid fertilizer storage barrel 51, and a flow meter 54 arranged at the rotary joint 52 and the input end of the fertilizer pump 53. The shell 61 is fixedly connected to the lower end of the frame 1 and sleeved on the outer surface of the inner tube of the rotary joint 52. The output end of the fertilizer pump 53 passes through the shell 61 and is connected to the serpentine tube body 611. The outer surface of the support plate 3 is fixedly connected to an irrigation unit 7 connected to the water-fertilizer mixing component 6 for spraying and discharging the mixed water and fertilizer.

[0041] The outer surface of the support plate 3 is fixedly connected to an irrigation unit 7 connected to the water-fertilizer mixing assembly 6 for spraying and discharging the mixed water and fertilizer; the irrigation unit 7 includes a fixing frame 71 fixedly connected to the outer surface of one side of the support plate 3, a pump body 72 fixedly connected to the fixing frame 71 and having an input end connected to the output end of the water-fertilizer mixing assembly 6, and a sprinkler assembly 73 fixedly connected to one side of the support plate 3 and connected to the output end of the pump body 72.

[0042] The outer surface of the frame 1 is also fixedly connected to a connecting unit 2, and the connecting unit 2 includes a connecting plate 21 fixedly connected to the upper and lower ends of the frame 1, a pin hole 22 opened inside the connecting plate 21, two side plates 23 fixedly connected to both sides of the connecting plate 21, and a positioning hole 24 opened inside the side plate 23.

[0043] By adopting the above technical solution, the connection unit 2 is designed to facilitate connecting the frame 1 with the hook pin of the tractor, and the hook pin of the tractor is inserted into the pin hole 22 in the connecting plate 21. When the tractor moves, it can pull the entire irrigation device to move. The positioning hole 24 in the connecting plate 21 is used to limit the hook pin. The positioning pin is inserted into the hook pin through the positioning hole 24, so that the hook pin cannot rotate and jump up and down in the pin hole 22, thereby ensuring the stability of the connection. The rotating joint 52 is externally connected to the irrigation water supply pipe, and the liquid fertilizer is stored in the liquid fertilizer storage barrel 51 in advance. The irrigation water enters the water-fertilizer mixing component 6 through the rotating joint 52, and the fertilizer pump 53 pumps the liquid fertilizer in the liquid fertilizer storage barrel 51 into the water-fertilizer mixing component 6. The irrigation water and the liquid fertilizer are mixed in the water-fertilizer mixing component. 6 can be mixed, the flow rate in the rotary joint 52 and the fertilizer pump 53 can be monitored by the flow meter 54, the fertilizer pump 53 can use a metering pump, by adding the flow meter 54, the speed of the fertilizer pump 53 is adjusted according to the information provided by the flow meter 54 to achieve the required water-fertilizer ratio, the irrigation water enters the static mixer 62 through the shell 1 61, the fertilizer pump 53 pumps the liquid fertilizer into the serpentine tube 611, and the liquid fertilizer is discharged from the drainage hole 612 on the serpentine tube 611, the mixing process can be started before the fluid enters the static mixer 62 (static mixer), so that the uniformity of the mixing can be improved, and at the same time, because the irrigation water and the liquid fertilizer have begun to contact and mix before entering the static mixer 62, this can reduce the mixing dead zone and improve the mixing efficiency.

[0044] like Figure 3 , Figure 8 and Fig. 9 As shown, the water-fertilizer mixing assembly 6 also includes a speed-increasing assembly 64 connected to the lower end of the static mixing element 62 for enhancing the friction and shear force between the fluids inside the static mixing element 62, and the speed-increasing assembly 64 includes a shell body 641, a cover body 642 movably connected to the lower end of the shell body 641, a motor 643 fixed to the lower end of the cover body 642, a rotating rod 644 rotatably arranged inside the shell body 641 and one end of which passes through the cover body 642 and is connected to the output shaft of the motor 643, and a propeller 645 fixed to the outer surface of the rotating rod 644.

[0045] By adopting the above technical solution, the rotation of motor 643 drives propeller 645 to rotate. The rotation of propeller 645 can increase the speed of the fluid inside shell four 641. Installing propeller 645 downstream of static mixer 62 can further increase the speed and kinetic energy of the fluid, which helps to improve the flow and transportation efficiency of the pipeline system. Increasing the fluid speed and kinetic energy helps to enhance the turbulent effect of the fluid, thereby promoting the mixing effect, improving the uniformity of the fluid, making the velocity distribution of the fluid on the cross section of the pipeline more uniform, and reducing the deviation and vortex of the fluid in the pipeline. At the same time, installing propeller 645 downstream of static mixer 62 can reduce the operating resistance of the pipeline system and reduce the pressure loss in the pipeline system. The increase in flow rate can help reduce the precipitation and scaling inside the water-fertilizer mixing component 6 and reduce the risk of blockage.

[0046] like Figure 3 , Figure 6 and Figure 7 As shown, the speed increasing assembly 64 also includes an isolation module 63 fixedly connected to the lower end of the static mixer 62 to connect the static mixer 62 with the shell 4 641, and the isolation module 63 includes a shell 3 631 connected between the static mixer 62 and the shell 4 641, a conical convergent end 632 and a conical diffuser end 633 respectively opened at the upper and lower parts of the shell 3 631, and a throat 634 opened at the shell 3 631 to connect the conical convergent end 632 with the conical diffuser end 633. The inner wall of the conical diffuser end 633 is fixedly connected with a guide vane 635 for preventing the vortex of the fluid in the shell 4 641 from driving the fluid in the shell 3 631 to form a vortex and making the fluid flow uniform.

[0047] By adopting the above technical scheme, when the fluid is discharged from the static mixer 62 and enters the interior of the shell three 631, when the fluid passes through the tapered convergent end 632 and the throat 634, the flow velocity of the fluid gradually increases when passing through the tapered convergent end 632, thereby reducing the flow cross-sectional area. This can not only cooperate with the speed increasing component 64 to accelerate the fluid flow velocity, but also reduce the mutual interference of the fluid between the static mixer 62 and the speed increasing component 64 (avoiding the influence of the fluid vortex on the static mixer 62 when the speed increasing component 64 is working). At the same time, the guide vanes 635 arranged on the inner wall of the tapered diffusion end 633 can help guide the fluid to flow along the expected path, making the flow direction of the fluid more stable and consistent, reducing the chaos of the fluid flow and the formation of vortices, and can also increase the kinetic energy of the fluid when passing through the diffusion end, thereby increasing the speed and pressure of the fluid. The guide vanes 635 cooperate with the tapered convergent end 632 to effectively solve the problem of mutual interference between the static mixer and the speed increasing component 64 when used simultaneously.

[0048] like Figure 5As shown, the static mixer 62 includes a second shell 621 fixedly connected to the lower end of the first shell 61, an inner barrel 622 rotatably connected to the inside of the second shell 621, a limiting hole 623 provided inside the second shell 621 and the inner barrel 622, a limiting pin 624 inserted in the limiting hole 623, a mixing element 627 movably connected to the inner wall of the inner barrel 622, a connecting seat 629 fixedly connected to the lower end of the mixing element 627, and a limiting ring 628 screwed to the lower end of the inner wall of the second shell 621 for limiting the mixing element 627. A slide groove 625 is provided on the inner wall of the inner barrel 622, and a slide bar 626 is slidably connected in the slide groove 625, and one side of the slide bar 626 is fixedly connected to the outer surface of the mixing element 627.

[0049] By adopting the above technical scheme, the inner barrel body 622 can rotate in the shell 621. When the static mixer 62 needs to mix irrigation water and liquid fertilizer, the inner barrel body 622 is limited by the limit pin 624 to prevent the inner barrel body 622 from rotating in the shell 621. After the limit pin 624 is pulled out, the mixing element 627 and the inner barrel body 622 are driven to rotate in the shell 621 through the driving mechanism. At this time, cleaning liquid is introduced into the static mixer 62. Through the rotation of the mixing element 627, the cleaning liquid can more evenly cover the surface inside the inner barrel body 622, and can remove dirt or residues attached to the surface. At the same time, after the limit ring 628 is screwed out of the shell 621, the slide bar 626 is moved out of the slide groove 1 625, and the mixing element 627 can be directly taken out of the inner barrel body 622, so that the leaf surface of the mixing element 627 can be directly cleaned.

[0050] like Fig. 9 - Fig.11 As shown, a movable groove 649 is provided inside the shell 641, and one end of the cover body 642 is movably inserted in the movable groove 649, a guide rod 6492 is fixedly connected to the inner wall of the movable groove 649, and one end of the guide rod 6492 passes through and is inserted into the cover body 642, a spring 6491 is sleeved on the outside of the guide rod 6492, and the two ends of the spring 6491 are respectively connected to the inner wall of the movable groove 649 and one side of the cover body 642, one end of the rotating rod 644 passes through the guide blade 635 and extends into the inner barrel body 622, and one end of the rotating rod 644 is integrally formed with a cross cam for inserting into the connecting seat 629 and driving the connecting seat 629 to rotate.

[0051] By adopting the above technical solution, the cover body 642 can move at the lower end in the shell body four 641. By manually pushing the cover body 642 to move upward, the cover body 642 squeezes the spring 6491 in the movable groove one 649 to shrink the spring 6491. At this time, the cover body 642 will drive the rotating rod 644 to move upward as well. The cross flange on the rotating rod 644 can be inserted into the connecting seat 629 at the lower end of the mixing element 627. The rotating rod 644 rotates to drive the mixing element 627 to rotate, thereby cleaning the inside of the static mixing element 62. At the same time, the speed of the fluid in the water-fertilizer mixing assembly 6 can be increased while cleaning, thereby improving the cleaning effect. It should be noted here that the contact surface between the movable groove one 649 and the cover body 642 must be provided with a sealing ring to prevent the liquid in the shell body four 641 from flowing out from the connection between the shell body four 641 and the cover body 642.

[0052] like Fig. 9 and Fig.10 As shown, the outer surface of the rotating rod 644 is also fixedly connected to the rod body 646, and the outer surface of the rod body 646 is also fixedly connected to the elastic paddle 647, and the inner wall of the shell 641 is integrally formed with a flange 648 for contacting the elastic paddle 647 to cause the rod body 646 and the rotating rod 644 to vibrate.

[0053] By adopting the above technical solution, when the cover body 642 moves upward and drives the rotating rod 644 to move upward, it can also drive the rod body 646 and the elastic paddle 647 to move upward. The elastic paddle 647 moves upward and can contact the flange 648. The rotating rod 644 rotates to drive the rod body 646 and the elastic paddle 647 to rotate. The elastic paddle 647 rotates and contacts the flange 648 to produce deformation. The elastic paddle 647 is reset after separating from the flange 648, so that the rod body 646 and the rotating rod 644 vibrate. The vibration of the rotating rod 644 can drive the mixing element 627 to vibrate, thereby improving the cleaning effect of the inside of the static mixing element 62 and shortening the cleaning time.

[0054] like Figure 1 and Fig.10 As shown, the upper end of the frame 1 is also connected to a pipeline positioning unit 8, and the pipeline positioning unit 8 includes a second slide groove 81 opened inside the frame 1, a support bracket 82 with one end fixed to the outer surface of the rotary joint 52, a movable groove 88 opened inside the support bracket 82, a slider 87 movably connected inside the movable groove 88 and slidingly connected to the second slide groove 81 at the lower end, a protrusion 83 and a plurality of positioning blocks 84 fixed to the upper end of the support bracket 82, a rubber gasket 85 fixed inside the positioning block 84, an arc-shaped support plate 89 movably connected inside one of the positioning blocks 84 and fixed to one side of the slider 87 at one end, and a step 86 integrally formed on the inner wall of the second slide groove 81.

[0055] By adopting the above technical solution, since the frame 1 moves with the tractor, the water pipe connected to the rotary joint 52 may be pulled and loosened. In order to prevent the water pipe from detaching from the rotary joint 52, the water pipe is supported by the support bracket 82, and the slider 87 on the support bracket 82 can slide along the slide groove 81, so that the support bracket 82 can rotate on the frame 1, and support the rotation of the rotary joint 52 and the water pipe. The contact area with the water pipe can be increased by the protrusion 83, and the water pipe in the support bracket 82 can be increased. The stability of the bracket 82 is improved, and the friction between the bracket 82 and the water pipe is increased by the rubber gasket 85 to prevent the water pipe from moving in the positioning block 84. When the slider 87 moves in the second slide groove 81, the step 86 in the second slide groove 81 can push the slider 87 into the second movable groove 88. The rise of the slider 87 can lift the arc support plate 89, so that the arc support plate 89 squeezes the water pipe and presses and positions the water pipe. In this way, when the support bracket 82 moves, the water pipe in the support bracket 82 can be prevented from moving and falling off from the connection with the rotary joint 52.

[0056] Instructions for use: First, connect the rotary joint 52 to the irrigation water supply pipe, store the liquid fertilizer in the liquid fertilizer storage barrel 51 in advance, then insert the hook pin of the tractor into the pin hole 22 in the connecting plate 21, and drive the tractor to move and drive the device to move. During the movement, the pump body 72 and the fertilizer pump 53 are controlled to work. The pump body 72 can pump the water-fertilizer integrated fertilizer liquid mixed in the water-fertilizer mixing component 6 to the sprinkler irrigation component 73. The sprinkler irrigation component 73 sprays the fertilizer liquid to realize water-fertilizer integrated irrigation. The mixing principle of the water-fertilizer mixing component 6 for irrigation water and liquid fertilizer is that the irrigation water enters the static mixing component 62 through the shell 1 61, and the fertilizer pump 53 pumps the liquid fertilizer into the snake The liquid fertilizer is premixed in the shell 61 and then enters the static mixer 62 from the shell 61. The fluid enters the isolation module 63 and the speed increasing component 64 after turbulent mixing in the mixing element 627 inside the static mixer 62. The speed increasing component 64 mixes the fluid again through vortex mixing and increases the speed of the fluid. After being discharged from the speed increasing component 64, the fluid enters the irrigation unit 7. The isolation module 63 can reduce the mutual interference of the fluid between the static mixer 62 and the speed increasing component 64, thereby reducing the chaos of the fluid flow and the formation of vortices.
