[0017] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Please see Figures 1 to 5 This application proposes a simplified variable fertilization device integrating water and fertilizer, including a water and fertilizer tank 11, a push-pull assembly 1, a lifting assembly 2, a spraying assembly 3, a transmission assembly 5, and a drive assembly 4. The push-pull assembly 1 includes a trolley 12 and a mounting box 13, with both the water and fertilizer tank 11 and the mounting box 13 mounted on the trolley 12. The lifting assembly 2 is located inside the mounting box 13. The spraying assembly 3 connects the lifting assembly 2 and the water and fertilizer tank 11. The transmission assembly 5 is connected to the spraying assembly 3. The drive assembly 4 is movably mounted in the mounting box 13 along the vertical direction. The drive assembly 4 connects the lifting assembly 2 and the transmission assembly 5 to cooperate with the lifting assembly 2 and the transmission assembly 5, so that the spraying assembly 3 can move in the vertical direction while rotating synchronously in the horizontal and vertical planes.

[0020] In the embodiments provided in this application, the trolley 12 is moved to the fertilization position by pushing and pulling the trolley 12, thereby moving the water and fertilizer tank 11 to the fertilization position, making it more convenient to use. The operation of the drive assembly 4 allows the lifting assembly 2 to move vertically and rotate simultaneously, thus moving the spraying assembly 3 vertically and horizontally, increasing the spraying range of the spraying assembly 3. The drive assembly 4 also moves the transmission assembly 5 while the lifting assembly 2 is moving, and in conjunction with the transmission assembly 5, it causes the spraying assembly 3 to rotate vertically, allowing it to move vertically and horizontally and vertically, further increasing the spraying range of water and fertilizer and improving the fertilization effect.

[0021] In some embodiments of this application, the lifting assembly 2 includes a lead screw 21 and a movable tube 22. One end of the lead screw 21 is fixedly connected to the inner bottom wall of the mounting box 13, and the other end extends out of the mounting box 13. The movable tube 22 is threadedly connected to the outer wall of the lead screw 21. The driving assembly 4 is connected to the movable tube 22 to make the movable tube 22 rotate. The movable tube 22 is connected to the spraying assembly 3.

[0022] The lead screw 21 extends vertically. When the drive assembly 4 drives the movable tube 22 to rotate, the movable tube 22 moves along the length of the lead screw 21 due to the threaded connection between the movable tube 22 and the lead screw 21. This allows the movable tube 22 to rotate while also moving vertically. Since the movable tube 22 is connected to the spraying assembly 3, the spraying assembly 3 can also rotate while moving vertically, increasing the spraying range of water and fertilizer.

[0023] In some embodiments of this application, the drive assembly 4 includes a square hole 47, a mounting base, a motor 41, a first bevel gear 45, and a second bevel gear 46. The square hole 47 is located on the side wall of the mounting box 13 and extends vertically. The mounting base is slidably connected to the inner wall of the square hole 47 and partially extends into the interior of the mounting box 13. The motor 41 is connected to the mounting base. The first bevel gear 45 is connected to the output shaft end of the motor 41. The second bevel gear 46 is fixedly connected to one end of the movable tube 22. The outer wall of the movable tube 22 is rotatably connected to the mounting base. The second bevel gear 46 meshes with the first bevel gear 45.

[0024] Start the motor 41 to make the first bevel gear 45 rotate. The first bevel gear 45 makes the second bevel gear 46 rotate, which in turn makes the movable tube 22 connected to the second bevel gear 46 rotate. When the movable tube 22 rotates, it will move along the length direction of the lead screw 21, and then move the mounting base and the motor 41 along the length direction of the square hole 47.

[0025] In some embodiments of this application, the spraying assembly 3 includes a liquid delivery chamber, a square box 36, a spray shell 32, a connecting pipe 37, a pressurized delivery pump 33, a liquid delivery hose 31, and a connecting pipe 34. The liquid delivery chamber is located on the wall of the movable pipe 22. The square box 36 is fixedly connected to the movable pipe 22, and the interior of the square box 36 communicates with the liquid delivery chamber. The spray shell 32 is provided with a plurality of atomizing nozzles 321 arranged at intervals along its length. The two ends of the connecting pipe 37 are respectively connected to the spray shell 32 and the square box 36. The pressurized delivery pump 33 is located on the water and fertilizer tank 11. One end of the liquid delivery hose 31 passes through the square hole 47 and connects to the movable pipe 22 and communicates with the liquid delivery chamber, and the other end is connected to the pressurized delivery pump 33. One end of the connecting pipe 34 extends into the interior of the water and fertilizer tank 11, and the other end is connected to the pressurized delivery pump 33.

[0026] Start the pressurized delivery pump 33 to deliver the water and fertilizer in the water and fertilizer tank 11 to the delivery chamber through the delivery hose 31. The water and fertilizer will then enter the interior of the square box 36, the interior of the connecting pipe 37, and the interior of the spray shell 32 in sequence through the delivery chamber and be sprayed out from multiple atomizing nozzles 321.

[0027] In some embodiments of this application, the mounting base includes a mounting body 42, a first mounting plate 44, and a second mounting plate 43. The first mounting plate 44 and the second mounting plate 43 are fixedly connected to both ends of the mounting body 42, respectively. The mounting body 42 is slidably connected to the inner wall of the square hole 47. The mounting body 42 is connected to the motor 41. The first mounting plate 44 is rotatably connected to the outer wall of the movable tube 22. The transmission assembly 5 includes a transmission tube 51, a third bevel gear 53, a fourth bevel gear 511, and a fifth bevel gear 52. The transmission tube 51 is rotatably inserted through the second mounting plate 43. The movable tube 22 passes through the transmission tube 51. The third bevel gear 53 is fixedly connected to one end of the transmission tube 51 and meshes with the first bevel gear 45. The fourth bevel gear 511 is fixedly connected to the other end of the transmission tube 51. The fifth bevel gear 52 is fixedly connected to the outer wall of the connecting tube 37 and meshes with the fourth bevel gear 511. The connecting tube 37 is rotatably connected to the square box 36.

[0028] When the motor 41 starts, it will not only cause the second bevel gear 46 and the movable tube 22 to rotate, but also the third bevel gear 53 and the transmission tube 51 to rotate. Since the first bevel gear 45 is located between the second bevel gear 46 and the third bevel gear 53, the rotation directions of the second bevel gear 46 and the third bevel gear 53 can be opposite, that is, the rotation directions of the movable tube 22 and the transmission tube 51 can be opposite. This allows the fifth bevel gear 52 to rotate on its own axis and around the transmission tube 51 during the meshing and transmission with the fourth bevel gear 511. When the fifth bevel gear 52 rotates, it can rotate the connecting tube 37 and cause the spray shell 32 to rotate in the vertical plane. When the movable tube 22 rotates, it can cause the spray shell 32 to rotate in the horizontal plane, thus realizing the synchronous rotation of the spray shell 32 in the vertical and horizontal planes.

[0029] In some embodiments of this application, the water and fertilizer tank 11 is provided with a stirring assembly 6, which includes a three-way pipe 61, a drive pipe 62, multiple spray pipes 621, a stirring rod 63, and multiple stirring blades 631. The three-way pipe 61 has a first connecting port, a second connecting port, and a third connecting port. The first connecting port end of the three-way pipe 61 is provided with a first solenoid valve 611 and connected to the infusion hose 31. The second connecting port end of the three-way pipe 61 is provided with a second solenoid valve 612 and is fixedly connected to the water and fertilizer tank 11. The third connecting port end of the three-way pipe 61 is connected to the pressurized delivery pump 33. The drive pipe 62 is located inside the water and fertilizer tank 11, and one end of the drive pipe 62 is rotatably connected to the second connecting port end of the three-way pipe 61. Multiple spray pipes 621 extend in an arc in the same direction and are arranged at intervals along the circumference of the drive pipe 62 on the outer peripheral wall of the drive pipe 62. The stirring rod 63 is fixedly connected to the other end of the drive pipe 62. Multiple stirring blades 631 are provided on the stirring rod 63.

[0030] When the first solenoid valve 611 is closed, the pressurized delivery pump 33 is started. The water and fertilizer in the water-fertilizer tank 11 enter the three-way pipe 61 through the third connecting port, and then enter the drive pipe 62 located inside the water-fertilizer tank 11 through the second connecting port. It is then sprayed out from multiple spray pipes 621. The reaction force of the water flow causes the drive pipe 62 to rotate, which in turn causes the stirring rod 63 and stirring blades 631 to rotate, thus stirring the water and fertilizer in the water-fertilizer tank 11. This makes the fertilizer and water mix more evenly and prevents the water and fertilizer from settling during transportation. The water-fertilizer solution sprayed from the multiple spray pipes 621 falls back into the water-fertilizer tank 11, which further improves the mixing effect of fertilizer and water.

[0031] Furthermore, the side wall of the water-fertilizer tank 11 is provided with an arc-shaped cleaning port 111, and a sealing plate 112 is provided at the arc-shaped cleaning port 111. The inner peripheral wall of the water-fertilizer tank 11 is connected to a filter screen 113 located below multiple spray pipes 621, and the stirring rod 63 rotates through the filter screen 113. In this way, the water-fertilizer sprayed from the spray pipes 621 will pass through the filter screen 113 below, and the filter screen 113 will filter out large particulate impurities in the water-fertilizer. When the water-fertilizer is sent to the atomizing nozzle 321, it can prevent large particulate impurities in the water-fertilizer from clogging the atomizing nozzle 321. By opening the sealing plate 112, the large particulate impurities accumulated on the filter screen can be cleaned away through the arc-shaped cleaning port 111.

[0032] The filter screen 113 is shaped like a frustum, and the bottom of the filter screen 113 can correspond to the arc-shaped cleaning port 111. In this way, large particles of impurities filtered on the filter screen 113 will automatically slide down to the position near the arc-shaped cleaning port 111, preventing impurities from clogging the filter screen 113. Furthermore, when the sealing plate 112 is opened, the large particles of impurities accumulated at the bottom of the filter screen 113 can be cleaned more quickly and conveniently.

[0033] A brush plate 622 is fixedly connected to the outer wall of the drive tube 62 and abuts against the filter screen 113. When the drive tube 62 rotates, the brush plate 622 will rotate. During the rotation process, the brush plate 622 will clean the large particles of impurities accumulated on the filter screen 113, further preventing large particles of impurities from clogging the filter screen 113 and improving the filtration effect of the filter screen 113.

[0034] Working principle: Before spraying the fertilizer solution, before moving the fertilizer tank 11 to the fertilization position or during the movement of the trolley 12, close the first solenoid valve 611 and open the second solenoid valve 612, starting the pressurized delivery pump 33. The pressurized delivery pump 33 causes the fertilizer solution in the fertilizer tank 11 to enter the drive pipe 62 through the three-way pipe 61 and be sprayed out from multiple spray pipes 621, thereby causing the drive pipe 62 and the half-rod to rotate, causing the stirring blades 631 to stir the fertilizer solution in the fertilizer tank 11, making the fertilizer and water mix more evenly and preventing sedimentation of the fertilizer solution during transportation. The fertilizer solution sprayed from the multiple spray pipes 621 is filtered through the filter screen 113 to prevent large particles of impurities in the fertilizer solution from clogging the atomizing nozzles 321.

[0035] When the water and fertilizer tank 11 is in the fertilization position, the second solenoid valve 612 is closed and the first solenoid valve 611 is opened. After the pressurized delivery pump 33 is started, the water and fertilizer will be sent through the delivery hose 31 to the delivery chamber of the movable tube 22, and finally sprayed out from the multiple atomizing nozzles 321 on the spray shell 32. Simultaneously, the motor 41 is started, causing the first bevel gear 45 to rotate, which in turn causes the second bevel gear 46 and the third bevel gear 53 to rotate, thus rotating the movable tube 22 and the transmission tube 51. When the movable tube 22 rotates, it moves along the length of the lead screw 21, thereby allowing the spray shell 32 to move vertically and horizontally, increasing the spraying range. During the rotation of the movable tube 22, the fifth bevel gear 52 will rotate around the transmission tube 51. The rotation of the transmission tube 51 will cause the fourth bevel gear 511 and the fifth bevel gear 52 to rotate in opposite directions in the horizontal plane, thereby causing the fifth bevel gear 52 to rotate and drive the connecting tube 37 to rotate, so that the spray shell 32 rotates in the vertical plane. Thus, the spray shell 32 can move vertically and simultaneously rotate in the horizontal and vertical planes, which can further effectively increase the spraying range of water and fertilizer and improve the fertilization effect.
