[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. Irrigation fertilization is a commonly used fertilization method in modern agriculture. Soluble solid or liquid fertilizers are usually applied according to the nutrients required by different crops and the characteristics of crop nutrient requirements. This fertilization method saves labor costs, improves fertilizer utilization, increases yield and income, and improves production efficiency.

[0003] According to Chinese Patent No. CN219555656U, a liquid fertilizer application device with good fertilization effect is disclosed, including a main body. A stirring mechanism is arranged in the middle of the main body, and a moving mechanism is arranged at the bottom of the main body. A solution tank is arranged at the left edge of the top of the main body. An inlet pipe is arranged at the top of the solution tank. A first groove is formed in the middle of the top of the inlet pipe. A piston is arranged at the top of the first groove. The stirring mechanism includes a drive motor. A first rotating shaft is arranged in the middle of the bottom of the drive motor. A first rotating column is arranged in the middle of the bottom of the first rotating shaft. Several sets of stirring blades are arranged on the outer wall of the first rotating column. The operator can aim the nozzle at the soil to be fertilized and spray fertilizer. The direction of the nozzle is controlled by pushing and using a second water pipe.

[0004] The liquid fertilizer application device in the above technical solution is convenient for controlling the nozzle. The worker can put himself inside the handrail and apply fertilizer to the land while pulling the application device. However, when using the device to apply fertilizer, the worker needs to hold the second water pipe. The location and amount of fertilizer application depend on the worker's experience, which can easily lead to uneven application.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crop fertilizer applicator that features uniform fertilization and saves manpower.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a crop fertilizer applicator, comprising a frame, a handle, and several wheels, wherein the wheels are rotatably connected to the side of the frame, the handle is fixedly connected to one side of the frame, a mixing tank is fixedly connected to the frame, a mixing device for mixing water and fertilizer is provided inside the mixing tank, a water pump is fixedly connected to the frame, the inlet of the water pump is connected to the inside of the mixing tank, the outlet of the water pump is connected to a water pipe, an adapter is connected to the end of the water pipe away from the water pump, and two water pipes are connected to the end of the adapter away from the water pipe, the two water pipes being corrugated pipes, each of the two water pipes being interconnected with the water pipe, and a spraying device is connected to the end of each water pipe away from the adapter.

[0008] By adopting the above technical solution, when fertilization is needed, water and fertilizer are first loaded into the mixing tank in proportion, and then the mixing device is started to fully mix the water and fertilizer in the mixing tank. The operator pushes the handle to turn the wheels and moves to the place where fertilization is needed. After arriving at the fertilization site, the water pump is started first. The water pump draws out the mixed solution in the mixing tank and sends it into water pipe one. Then, through the adapter, the solution in water pipe one is sent into water pipe two. Finally, it enters the spraying device through water pipe two and sprays the solution onto the place where fertilization is needed. Water pipe two can extend and swing back and forth during the spraying process, so that the spraying device can spray a wider and more uniform range. Fertilizer can be applied to the land on both sides at the same time while the fertilizer applicator is moving forward, which improves the spraying efficiency.

[0009] The present invention is further configured such that: the stirring device includes a motor, a stirring shaft and a plurality of stirring blades, the motor is disposed above the stirring tank, the stirring shaft is fixedly connected to the output end of the motor and extends into the interior of the stirring tank, and the plurality of stirring blades are fixedly connected to the stirring shaft.

[0010] By adopting the above technical solution, after water and fertilizer are put into the mixing tank, the motor is started. The motor drives the mixing shaft to start rotating, and several mixing blades on the mixing shaft start to stir the solution in the mixing tank, so that the fertilizer and water are fully mixed. The mixing can be carried out continuously while fertilizing, avoiding fertilizer sedimentation. No manual stirring is required, saving manpower.

[0011] The present invention is further configured such that: the spraying device includes a connecting pipe and a plurality of nozzles, one end of the connecting pipe is connected to and communicates with the second water pipe, the nozzles are fixedly connected to the side of the connecting pipe away from the second water pipe, the nozzles and the interior of the connecting pipe are in communication, the end of the connecting pipe away from the frame is bent upward, the frame is provided with a control mechanism for controlling the rotation of the connecting pipe, and a plug is detachably connected to the end of the connecting pipe away from the second water pipe.

[0012] By adopting the above technical solution, after arriving at the location where fertilization is needed, the solution in the mixing tank enters water pipe one through a water pump, and then enters two water pipes two through an adapter. From water pipe two, it enters the connecting pipe, and the solution is sprayed out from the nozzle. The end of the connecting pipe away from the frame bends upward to make the spraying range of the nozzle wider and prevent the solution from being sprayed onto the frame. The connecting pipe swings back and forth through a control mechanism to make the solution spray more evenly. When the connecting pipe is blocked or the nozzle is damaged, the plug can be opened to repair the connecting pipe or nozzle.

[0013] The present invention is further configured such that: a protective shell is fixedly connected to the frame, the protective shell is sleeved on the outside of the mixing tank, a cover is detachably connected to the top of the protective shell, the motor is fixedly connected to the top of the cover, and an opening is provided on the protective shell for the connecting pipe to extend out.

[0014] By adopting the above technical solution, when using this fertilizer applicator, the protective shell protects the internal parts of the fertilizer applicator, with only the connecting pipe extending out of the protective shell to fertilize the soil. This protects the parts and also the safety of the workers. When internal parts malfunction or are damaged, the cover can be opened to repair them.

[0015] The present invention is further configured such that: the control mechanism includes a ring and a gear; the ring is disposed near the bottom of the cover on the stirring shaft; a plurality of gear teeth are provided on 1 / 4 of the ring surface; the gear is slidably connected to the bottom of the cover; gear teeth are fixedly connected to the inner side of the cover; the gear meshes with gear teeth and gear teeth respectively; two connecting cylinders are disposed below the cover; one connecting cylinder is fixedly connected to the gear via a connecting shaft; the other connecting cylinder is disposed inside the protective shell on the side away from the gear; the connecting tube is detachably connected to the connecting cylinder; and a reset component for resetting the connecting tube is disposed below the connecting cylinder.

[0016] By adopting the above technical solution, when using the fertilizer applicator for fertilization, the solution is sprayed onto the soil through the nozzle. When the stirring shaft rotates, it drives the ring to rotate. When several gear teeth on the ring mesh with the gear, the gear begins to make a circular motion along the direction of the ring's rotation. While making a circular motion, the gear meshes with gear teeth on its own rotation. Gear teeth on both sides simultaneously engage the gear, making the gear's movement more stable. While the gear is making a circular motion, it drives the connecting cylinder to move. The connecting pipe is connected inside the connecting cylinder and moves with the connecting cylinder. When gear teeth no longer mesh with the gear, the reset component starts to work, sending the connecting pipe back to its initial position, realizing the back-and-forth swing of the connecting pipe, making the fertilizer applicator apply fertilizer more evenly.

[0017] The present invention is further configured such that: the reset assembly includes a connecting rod and a moving wheel; the connecting rod is fixedly connected to the bottom of the connecting cylinder; the moving wheel is connected to the end of the connecting rod away from the connecting cylinder by a spring; a groove for the moving wheel to move is provided on the frame; the length of the groove is equal to the distance the moving wheel can move; and the bottom of the groove forms an inclined surface from low to high along the rotation direction of the stirring shaft.

[0018] By adopting the above technical solution, when the fertilizer applicator is applying fertilizer, the connecting rod moves under the drive of the connecting cylinder. The moving wheel is in close contact with the bottom of the groove. When the connecting rod moves, the moving wheel moves in the same direction as the connecting rod. The bottom of the groove forms an inclined plane from low to high along the direction of stirring rotation, and the spring begins to be compressed. When the connecting rod stops moving, the spring begins to rebound, and the movement begins from high to low along the bottom of the groove until it returns to the lowest point of the groove. The connecting cylinder is connected to the connecting rod. When the connecting rod moves, it drives the connecting cylinder to move, realizing the back-and-forth swing of the connecting pipe, so that the spray nozzle sprays more evenly, achieving the purpose of more even fertilization by the fertilizer applicator.

[0019] The present invention is further configured such that the two connecting rods are connected by a connecting rod.

[0020] By adopting the above technical solution, when the gear moves, it drives one of the connecting rods to move. The two connecting rods are connected by a connecting rod, so that the two connecting rods move at the same time, and the connecting rods on both sides can swing back and forth at the same time.

[0021] In summary, this utility model has the following beneficial effects: When fertilization is needed, water and fertilizer are first put into the mixing tank in proportion, and then the mixing device is started to fully mix the water and fertilizer in the mixing tank. The operator pushes the handle to turn the wheels and move to the place where fertilization is needed. After arriving at the fertilization site, the water pump is started first. The water pump draws out the mixed solution in the mixing tank and sends it into water pipe one. Then, through the adapter, the solution in water pipe one is sent into water pipe two. Finally, it enters the spraying device through water pipe two and sprays the solution onto the place where fertilization is needed. Water pipe two can extend and swing back and forth during the spraying process, so that the spraying device can spray a wider and more uniform range. Fertilizer can be applied to the land on both sides at the same time while the fertilizer applicator is moving forward. Moreover, the spraying device eliminates the need for manual spraying, saving manpower and improving spraying efficiency. Attached Figure Description

After water and fertilizer are added to the stirring tank 4, the motor 9 is started, and the motor 9 drives the stirring shaft 10 to start rotating. The several stirring blades 11 on the stirring shaft 10 begin to stir the solution in the stirring tank 4, so that the fertilizer and water are fully mixed. The stirring can be continuous while fertilizing, avoiding fertilizer sedimentation. No manual stirring is required, saving manpower.

[0034] In one embodiment, the spraying device includes a connecting pipe 12 and several nozzles 13. One end of the connecting pipe 12 is connected to and communicates with a second water pipe 8. The nozzles 13 are fixedly connected to the side of the connecting pipe 12 away from the second water pipe 8, and are internally communicated with the connecting pipe 12. The end of the connecting pipe 12 away from the frame 1 is bent upwards. A control mechanism for controlling the rotation of the connecting pipe 12 is provided on the frame 1. A plug 14 is detachably connected to the end of the connecting pipe 12 away from the second water pipe 8. After reaching the location where fertilization is needed, the solution in the mixing tank 4... The solution enters through pump 5 into pipe 6, then through adapter 7 into two pipes 8, and then into connecting pipe 12. The solution is sprayed out from nozzle 13. The end of connecting pipe 12 away from frame 1 is bent upwards, so that the spraying range of nozzle 13 is wider and the solution is prevented from being sprayed onto frame 1. Connecting pipe 12 swings back and forth through control mechanism to make the solution spray more evenly. When connecting pipe 12 is blocked or nozzle 13 is damaged, plug 14 can be opened to repair connecting pipe 12 or nozzle 13.

[0035] In one embodiment, a protective shell 15 is fixedly connected to the frame 1. The protective shell 15 is fitted over the outside of the mixing tank 4. A cover 16 is detachably connected to the top of the protective shell 15. The motor 9 is fixedly connected to the top of the cover 16. An opening 27 is provided on the protective shell 15 for the connecting pipe 12 to extend out. When using this fertilizer applicator, the protective shell 15 protects the internal parts of the fertilizer applicator. Only the connecting pipe 12 extends out of the protective shell 15 to fertilize the soil. This protects the parts and also protects the safety of the workers. When the internal parts malfunction or are damaged, the cover 16 can be opened to repair the internal parts.

[0036] like Figure 3 and Figure 6As shown, the control mechanism includes a ring 17 and a gear 18. The ring 17 is located near the bottom of the cover 16 on the stirring shaft 10. A number of gear teeth 19 are provided on a quarter-circle surface of the ring 17. The gear 18 is slidably connected to the bottom of the cover 16. A second gear tooth 20 is fixedly connected to the inner side of the cover 16. The gear 18 meshes with both gear teeth 19 and gear teeth 20. Two connecting cylinders 21 are located below the cover 16. One connecting cylinder 21 is fixedly connected to the gear 18 via a connecting shaft. The other connecting cylinder 21 is located inside the protective shell 15 on the side away from the gear 18. The connecting pipe 12 is detachably connected to the connecting cylinder 21. A reset assembly for resetting the connecting pipe 12 is located below the connecting cylinder 21. When using the fertilizer applicator for fertilization, the solution flows through the nozzle 1... 3. Spraying onto the soil, the mixing shaft 10 rotates, driving the ring 17 to rotate as well. When several gear teeth 19 on the ring 17 mesh with the gear 18, the gear 18 begins to move in a circular motion along the rotation direction of the ring 17. While moving in a circular motion, the gear 18 meshes with the gear teeth 20 through its own rotation. The gear teeth 19 and 20 on both sides simultaneously engage the gear 18, making the movement of the gear 18 more stable. While the gear 18 is moving in a circular motion, it drives the connecting cylinder 21 to move. The connecting pipe 12 is connected inside the connecting cylinder 21 and moves with the connecting cylinder 21. When the gear teeth 19 no longer mesh with the gear 18, the reset component starts to work, sending the connecting pipe 12 back to its initial position, realizing the back-and-forth swing of the connecting pipe 12, making the fertilizer application by the fertilizer applicator more uniform.

[0037] In one embodiment, the reset assembly includes a connecting rod 22 and a moving wheel 23. The connecting rod 22 is fixedly connected to the lower part of the connecting cylinder 21.

The length of the groove 25 is equal to the distance that the moving wheel 23 can move. The bottom of the groove 25 forms an inclined surface from low to high along the rotation direction of the stirring shaft 10. When the fertilizer applicator is fertilizing, the connecting rod 22 moves under the drive of the connecting cylinder 21, and the moving wheel 23 is in close contact with the bottom of the groove 25. When the connecting rod 22 moves, the moving wheel 23 moves in the same direction as the connecting rod 22. The bottom of the groove 25 forms an inclined plane from low to high along the direction of stirring rotation, and the spring 24 is compressed. When the connecting rod 22 stops moving, the spring 24 begins to rebound, and the movement begins from high to low along the bottom of the groove 25 until it returns to the lowest point of the bottom of the groove 25. The connecting cylinder 21 is connected to the connecting rod 22. When the connecting rod 22 moves, it drives the connecting cylinder 21 to move, realizing the back-and-forth swing of the connecting pipe 12, so that the nozzle 13 sprays more evenly, achieving the purpose of more even fertilization by the fertilizer applicator. The two connecting rods 22 are connected by the connecting rod 26. When the gear 18 moves, it drives one of the connecting rods 22 to move. The two connecting rods 22 are connected by the connecting rod 26, so that the two connecting rods 22 move simultaneously, realizing that the connecting rods 22 on both sides can swing back and forth at the same time.

[0038] The method of using this utility model is as follows:

[0039] When fertilization is needed, water and fertilizer are first put into the mixing tank 4 in proportion. Then, the mixing device is started to mix the water and fertilizer thoroughly in the mixing tank 4. The worker pushes the handle 2 to turn the wheel 3 and moves to the place where fertilization is needed. After arriving at the fertilization site, the water pump 5 is started. The water pump 5 draws out the mixed solution in the mixing tank 4 and sends it into the first water pipe 6. Then, the solution in the first water pipe 6 is sent into the second water pipe 8 through the adapter 7. Finally, the solution enters the connecting pipe 12 through the second water pipe 8 and is sprayed from the nozzle 13 onto the place where fertilization is needed. The connecting cylinder 21 is driven to make a circular motion by the gear 18. The spring 24 on the connecting rod 22 uses elastic potential energy to make the connecting cylinder 21 return to its original position, so that the connecting pipe 12 swings back and forth, which improves the fertilization efficiency and saves manpower.
