Description

Technical Field

[0001] This invention relates to the field of water and fertilizer irrigation technology, specifically to an integrated water and fertilizer irrigation device. Background Technology

[0002] Water and fertilizer are two crucial factors affecting crop growth, and researching and exploring technologies and methods to improve crop productivity through fertilization and irrigation has always been a hot topic in agricultural research. With the development of irrigation technology, modern agriculture is gradually moving towards the use of integrated water and fertilizer drip irrigation systems. Fertilization through irrigation systems allows crops to absorb nutrients while absorbing water, easily achieving small, frequent applications of fertilizer. Fertilization can be done according to the crop's nutrient requirements. Furthermore, it reduces fertilizer waste caused by volatilization and spraying, thus greatly improving fertilizer utilization. Liquid fertilizers have been widely used in modern agricultural production. Integrated water and fertilizer technology is a new agricultural technology that combines irrigation and fertilization. Irrigation is achieved through pipes and nozzles, uniformly, regularly, and quantitatively soaking the crop's root development area, keeping the soil around the main root system loose and with suitable moisture content. This fertilization method saves labor costs, improves fertilizer utilization, increases yield and income, and enhances production efficiency.

[0003] Chinese patent application CN117242970A discloses a water and fertilizer irrigation device and method for planting shrubs and grasses in mines. The water and fertilizer irrigation device for planting shrubs and grasses in mines includes a vehicle-mounted pallet, a mixing drum installed on the vehicle-mounted pallet, a liquid outlet pipe connected to the mixing drum and perpendicular to the side of the mixing drum, and a water pump connected to the liquid outlet pipe at the water inlet side. A spraying system located on the side of the vehicle-mounted pallet is installed on the water outlet side of the water pump. The spraying system includes a spray pipe connected to the water outlet side of the water pump, a first spray pipe and a second spray pipe connected to the spray pipe via a hose. While the first spray pipe and the second spray pipe, carrying these nozzles, move frequently in a straight line on the side of the vehicle-mounted pallet, the sprayed fertilizer mixture can be sprayed more evenly onto the vegetation or soil, achieving uniform application and improving the irrigation quality during fertilizer irrigation.

[0032] The following will be combined with the appendix Figures 1 to 10 The technical solutions of the present invention have been clearly and completely described. 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.

[0033] This invention provides an integrated water and fertilizer irrigation device through improvements, such as... Figures 1-10As shown, the device includes a vehicle body 1, on which a water tank 2 is mounted. A motion mechanism 8 is movably mounted on the top of the water tank 2. The motion mechanism 8 includes a rotating ring 9, with a suspension 15 fixedly mounted at the bottom of the rotating ring 9 and two sets of symmetrical crossbeams 14 fixedly mounted at the top of the rotating ring 9. Two sets of sliding rods 16 are arranged between the suspension 15 and the crossbeams 14. Symmetrical swinging components 17 are mounted on the crossbeams 14, and a swing frame 22 is movably mounted between the sliding rods 16. An active swing shaft 18 is also eccentrically mounted on the two sets of swinging components 17. Swing shafts 23 are arranged on both sides of the swing frame 22, and the active swing shaft 18 is movably connected to the swing shafts 23. A mesh cage frame 25 is also connected to both sides of the swing shaft 23. A soaking tank 27 is detachably mounted on the outer wall of the mesh cage frame 25. When the swinging component 17 drives the soaking tanks 27 on both sides to swing back and forth, the fertilizer in the soaking tanks 27 is fully dissolved into the water in the water tank 2.

[0034] In this embodiment, the integrated water and fertilizer irrigation equipment mainly consists of three parts: a vehicle body 1, a water tank 2, and a soaking tank 27. When using the equipment, various solid fertilizers and additives are first added to the soaking tank 27. Then, the soaking tank 27 is installed onto the track 26 of the mesh frame 25 via the quick-connect boss 28. Next, the swing motor 38 is started, and the worm gear 40 on the drive rod 39 drives the second drive gear 36 and the left swinging component 17 to rotate. The moving worm 41 on the drive rod 39 drives the second drive gear 36 and the right swinging component 17 to rotate, thereby causing the swing frame 22 and the soaking tank 27 to move up and down along the slide rod 16 while swinging left and right. Then, the rotary motor 12 is started. When the entire motion mechanism 8 rotates, multiple sets of brushes 32 clean the filter screen 6 repeatedly to prevent clogging.

[0035] See appendix Figure 1 and attached Figure 5 A gear ring 11 is installed on the outer wall of the rotating ring 9, and a rotary motor 12 is installed on the water tank 2. A drive gear 13 that meshes with the gear ring 11 is installed at the output end of the rotary motor 12.

[0036] In this embodiment: to drive the motion mechanism 8 to rotate as a whole, thereby further improving the dissolution efficiency and cleaning the filter screen 6, a rotatable rotating ring 9 structure is designed. To drive the rotating ring 9 to rotate, a rotary motor 12 structure is designed.

[0037] See appendix Figure 6 The top of the crossbeam 14 is provided with symmetrical rotating seats 35, and the two outer walls of the swing member 17 are provided with drive shafts 19. The swing member 17 is rotatably disposed between the rotating seats 35 through the drive shafts 19. The active swing shaft 18 is movably mounted with a linkage arm 24, and the bottom of the linkage arm 24 is movably connected to the swing shaft 23.

[0038] In this embodiment, the two swinging members 17 are symmetrically installed between the rotating seats 35, but they maintain asynchronous movement, so that the swing frame 22 can be driven to swing back and forth.

[0039] See appendix Figure 6 -Appendix Figure 8 A horizontal mounting bracket 37 is provided on the outer wall of one of the crossbeams 14. A swing motor 38 is mounted on the mounting bracket 37. A drive rod 39 is provided at the output end of the swing motor 38. A second drive gear 36 is mounted on the outer side of the drive shaft 19. A worm gear part 40 is provided on the drive rod 39 to mesh with one of the second drive gears 36. A moving worm cylinder 41 that meshes with another set of second drive gears 36 is also movably sleeved on the drive rod 39.

[0040] In this embodiment: when the swing motor 38 starts and drives the drive rod 39 to rotate, the worm gear 40 drives the second drive gear 36 and the left swing member 17 to rotate, and the moving worm 41 drives the second drive gear 36 and the right swing member 17 to rotate.

[0041] See appendix Figure 7 -Appendix Figure 8 Multiple sets of sliding grooves 44 are provided on the outer wall of the drive rod 39, and a linkage through hole 42 is provided in the middle of the moving worm 41. A limiting protrusion 43 that cooperates with the sliding groove 44 is provided on the inner wall of the linkage through hole 42.

[0042] In this embodiment: when the moving worm 41 moves along the drive rod 39, in order to keep it in a linked state, the drive rod 39 can drive the moving worm 419 to rotate synchronously, so a mutually cooperating slide groove 44 and limiting protrusion 43 structure is designed.

[0043] See appendix Figure 6 -Appendix Figure 8 An adjusting motor 45 is also installed on the mounting bracket 37. The output end of the adjusting motor 45 is provided with a threaded rod 46, and a threaded sleeve 47 is threadedly installed on the threaded rod 46. A connecting arm 48 is provided at the end of the threaded sleeve 47, and the end of the connecting arm 48 is fixedly connected to the moving worm gear 41.

[0044] In this embodiment: When dissolving solid fertilizer and additives, an adjusting motor 45 is designed to adjust the swing amplitude of the swing frame 22 and the soaking tank 27 as needed. The tops of the two side linkage arms 24 move in a circular motion relative to the crossbeam 14, with high and low points in their trajectory. When the adjusting motor 45 starts and adjusts the threaded sleeve 47 inward, the connecting arm 48 drives the moving worm gear 41 to slide inward, that is, towards the left swing member 17. Since the moving worm gear 41 meshes with the drive gear 36, the right swing member 17 swings clockwise at this time.

[0045] When the linkage arm 24 on the left swing member 17 moves to the highest point, the linkage arm 24 on the right swing member 17 moves to the lowest point. After the right swing member 17 swings clockwise, the height difference between the linkage arms 24 on both sides becomes smaller, so the swing amplitude of the swing frame 22 and the soaking tank 27 will also become smaller.

[0046] See appendix Figure 6 and attached Figure 9 A sliding sleeve 20 is slidably mounted on the sliding rod 16, and a connecting rod 21 is fixedly connected between the sliding sleeves 20. The middle part of the swing frame 22 is movably connected to the connecting rod 21.

[0047] In this embodiment: when the swing member 17 moves in a misaligned manner, under the linkage action of the linkage arm 24, the linkage arm 24 rotates relative to the rotating seat 35, so the sliding sleeve 20 moves up and down along the slide rod 16. Since there is an angular difference when the two swing members 17 move, the two ends of the swing frame 22 swing back and forth, and the middle part of the swing frame 22 is movably connected to the connecting rod 21. Therefore, the movement trajectory of the swing frame 22 is: moving up and down along the slide rod 16 while swinging left and right.

[0048] See appendix Figure 6 and attached Figure 10 The cage frame 25 has a track 26 in the middle, and the soaking tank 27 has a quick-connect boss 28 that is slidably installed in the track 26 on the inner side; the top of the soaking tank 27 is movably installed with a flip cover 29, and a rope ring 30 is provided on the flip cover 29.

[0049] In this embodiment: when the net cage frame 25 swings, it also synchronously drives the soaking tank 27 to reciprocate. To facilitate the installation and quick disassembly of the soaking tank 27, a matching track 26 and a quick-connect boss 28 structure are designed. When it is necessary to remove the soaking tank 27, the rope is pulled upward to lift the soaking tank 27 out of the water. A rope (not shown) is connected to the rope loop 30.

[0050] See appendix Figure 3 -Appendix Figure 5 The bottom of the water tank 2 is equipped with multiple sets of spray pipes 5, and multiple filter screens 6 located at the water inlet end of the spray pipes 5 are installed at the bottom of the water tank 2; the bottom of the suspension 15 is fixedly equipped with a linkage shaft 31, and multiple sets of brushes 32 are installed on the linkage shaft 31; the bottom of the water tank 2 is also equipped with a slag discharge pipe 33.

[0051] In this embodiment: when the motion mechanism 8 rotates relative to the water tank 2, multiple sets of brushes 32 at the bottom will reciprocate to clean the filter screen 6, preventing residual sediment in the water from clogging the filter screen 6 and thus affecting the spraying operation of the nozzle 5. The vehicle body 1 is also equipped with multiple water pumps (not shown) that independently control each individual nozzle 5.

[0052] See appendix Figure 1 -Appendix Figure 5 The top of the water tank 2 is provided with a rotating cavity 3, and a limiting seat 4 is provided on the rotating cavity 3. A limiting ring 10 that cooperates with it is provided on the outer wall of the rotating ring 9. Multiple observation windows 7 are provided on the water tank 2. A control panel 34 is provided on the vehicle body 1.

[0053] In this embodiment: when the motion mechanism 8 rotates relative to the water tank 2, a limiting seat 4 structure is designed to improve stability during rotation. An observation window 7 is designed to facilitate observation of the interior of the water tank 2. A control panel 34 structure is designed to control the operation of the equipment.

[0054] The working principle of this invention is as follows: When using the device, various solid fertilizers and additives are first added to the soaking tank 27. Then, the soaking tank 27 is installed onto the track 26 of the mesh frame 25 via the quick-connect boss 28. Next, the swing motor 38 is started. The worm gear 40 on the drive rod 39 drives the second drive gear 36 and the left swinging component 17 to rotate. The moving worm 41 on the drive rod 39 drives the second drive gear 36 and the right swinging component 17 to rotate, thereby causing the swing frame 22 and the soaking tank 27 to move up and down along the slide rod 16 while swinging left and right. Then, the rotary motor 12 is started. When the entire motion mechanism 8 rotates, multiple sets of brushes 32 clean the filter screen 6 repeatedly to prevent clogging.

[0055] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
