Description

Technical Field

[0001] This utility model relates to the field of fertilization equipment technology, and in particular to a device for fertilizing farmland. Background Technology

[0002] To supplement the nutrients needed for crop growth, chemical fertilizers are commonly used in farmland. A traditional and scientific fertilization method is to apply fertilizer in small pits near the crop roots ("hole application"). By digging small pits (generally 5-15 cm deep) near the roots, placing the fertilizer in, and then covering it with soil, fertilizer loss due to rainwater runoff is reduced. This concentrates the fertilizer around the roots, facilitating crop absorption (shortening nutrient diffusion distance and improving utilization). This method is particularly suitable for solid fertilizers (such as urea and compound fertilizers), preventing exposure to volatilization or decomposition by surface microorganisms, and also reducing the risk of root burn (the fertilizer is appropriately isolated from the roots after covering with soil). However, the equipment used for this fertilization is usually the most basic (e.g., shovels or hoes). Using such tools requires manual repetition of digging pits, spreading fertilizer, and covering with soil, necessitating hundreds of bending movements per acre, resulting in extremely low efficiency. Utility Model Content

[0003] The purpose of this invention is to address the problem that current farmland fertilization tools, such as shovels or hoes, require manual digging, spreading fertilizer, and covering with soil repeatedly, resulting in hundreds of bends per acre and extremely low efficiency. This invention proposes a device for farmland fertilization.

[0004] The technical solution of this utility model is as follows: A device for fertilizing farmland includes a hopper and a discharge pipe fixedly connected to the bottom of the hopper. A fine shovel is fixedly connected to the bottom end of the discharge pipe, and a discharge port for inserting into the farmland soil is also opened at the end of the discharge pipe near the fine shovel. A quantitative fertilization mechanism is slidably disposed at the bottom of the discharge pipe. A positioning rotating plate is rotatably connected to the middle of the fine shovel, and a switching mechanism is provided on the discharge pipe to drive the quantitative fertilization mechanism to open after the positioning rotating plate abuts against the farmland surface and bends the discharge pipe.

[0005] Optionally, the quantitative fertilization mechanism includes a pair of first sluices at the bottom of the discharge pipe, a second sluice at the bottom of the discharge pipe, a drive plate at the bottom of the discharge pipe, a first blocking plate whose end is inserted into the second sluice fixedly connected to the top of the drive plate, and a second blocking plate whose end is inserted into the first sluice fixedly connected to the bottom of the drive plate, and a material passage hole is provided on the second blocking plate.

[0006] Optionally, the switching mechanism includes a connecting rope, one end of which is fixedly connected to the upper surface of one end of the positioning rotating plate, a protrusion fixedly connected to one end of the second blocking plate near the driving plate, the protrusion being fixedly connected to the other end of the connecting rope, a support block fixedly connected to the bottom outer wall of the discharge pipe, and a second spring movably sleeved on one end of the connecting rope near the protrusion, one end of the second spring being fixedly connected to the protrusion, and the other end of the second spring being fixedly connected to the support block.

[0007] Optionally, a slide rod is slidably inserted on the support block, and a stop block is fixedly connected to the bottom end of the slide rod. A first spring is movably sleeved on the slide rod, with one end of the first spring fixedly connected to the lower surface of the support block and the other end of the first spring fixedly connected to the stop block.

[0008] Optionally, a foot pedal is fixedly connected to the bottom outer wall of the discharge pipe, and the foot pedal has multiple anti-slip grooves arranged in a linear pattern.

[0009] Optionally, a filter screen is fixedly connected inside the hopper.

[0010] Optionally, handles are fixedly connected to both outer walls of the hopper.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] The combination of the discharge pipe, fine shovel, discharge port, quantitative fertilizer application mechanism, positioning rotating plate, and switching mechanism in this utility model allows the quantitative fertilizer application mechanism to be driven by bending the discharge pipe after inserting the fine shovel into the farmland soil. This enables a fixed amount of fertilizer to flow into the inclined pit squeezed out by the fine shovel through the material penetration hole and discharge port. This eliminates the need for manual digging, spreading fertilizer, and covering with soil, reducing bending over and achieving quick, labor-saving, and efficient fertilization, thus improving fertilization efficiency and reducing labor intensity.

[0026] Example

[0027] like Figures 1 to 6 As shown, this utility model proposes a device for fertilizing farmland, including a hopper 1. A filter screen 11 is fixedly connected inside the hopper 1. The filter screen 11 filters fertilizer particles, preventing clumping or impurities from entering the discharge pipe 2. Handles 12 are fixedly connected to both outer walls of the hopper 1 for easy gripping and operation. The discharge pipe 2 is fixedly connected to the bottom of the hopper 1. A pedal 5 is fixedly connected to the bottom outer wall of the discharge pipe 2 for the user to step on, making it easier and faster for the fine shovel 21 to penetrate the soil. Multiple linearly arranged anti-slip grooves are provided on the pedal 5 to increase the friction between the foot and the pedal 5, achieving an anti-slip effect.

[0028] Among them, such as Figures 1 to 6 As shown, a fine shovel 21 is fixedly connected to the bottom end of the discharge pipe 2. The fine shovel 21 is less likely to carry soil after digging because its sharp blade and smooth surface reduce friction when inserted into the soil. Furthermore, the fine shovel compresses the soil into a slanted pit, reducing soil adhesion rather than digging. A discharge port 3, which is inserted into the farmland soil, is also provided at the end of the discharge pipe 2 near the fine shovel 21. The discharge port 3 is the channel for fertilizer to flow out. A positioning plate 28 is rotatably connected to the middle of the fine shovel 21. The positioning plate 28 is used to press against the farmland surface for positioning and to trigger the switching mechanism. The switching mechanism is used to make the positioning plate 28 press against the farmland surface and bend the discharge pipe 2, thereby driving the quantitative fertilizer application mechanism to open.

[0029] Secondly, such as Figures 4 to 6As shown, a quantitative fertilizer application mechanism is slidably provided at the bottom of the discharge pipe 2. This mechanism includes a pair of first grooves 22 at the bottom of the discharge pipe 2, and a second groove 23 at the bottom of the discharge pipe 2. A drive plate 4 is located at the bottom of the discharge pipe 2. A first blocking plate 41, whose end is inserted into the second groove 23, is fixedly connected to the top of the drive plate 4. The first blocking plate 41, inserted into the second groove 23, cuts off the inner cavity of the discharge pipe 2, controlling the flow of fertilizer. A second blocking plate 42, inserted into the first groove 22, is fixedly connected to the bottom of the drive plate 4. The second blocking plate 42 has a material through hole 43, which controls the discharge of fertilizer. The material through hole 43 is aligned with the discharge port 3, allowing fertilizer to flow out of the discharge pipe 2.

[0030] In addition, such as Figures 2 to 6 As shown, the discharge pipe 2 is equipped with a switching mechanism, which includes a connecting rope 46 made of steel wire rope. One end of the connecting rope 46 is fixed to the positioning rotating plate 28, and the other end is fixed to the protrusion 44, transmitting the power for the rotation of the positioning rotating plate 28. One end of the connecting rope 46 is fixedly connected to the upper surface of one end of the positioning rotating plate 28. The second blocking plate 42 is fixedly connected to the protrusion 44 at one end near the driving plate 4. The protrusion 44 is fixedly connected to the other end of the connecting rope 46. A support block 24 is fixedly connected to the bottom outer wall of the discharge pipe 2. A second spring 45 is movably sleeved on the end of the connecting rope 46 near the protrusion 44. One end of the second spring 45 is fixed to the protrusion 44, and the other end is fixed to the support block 24, providing elastic thrust. One end of the second spring 45 is fixedly connected to the protrusion 44, and the other end of the second spring 45 is fixedly connected to the support block 24.

[0031] It is worth noting that, such as Figure 2 , Figure 5 and Figure 6 As shown, a sliding rod 25 is slidably inserted into the support block 24. The sliding rod 25 is slidably inserted into the support block 24, and its bottom end is connected to a stop block 27, stabilizing the auxiliary device. The stop block 27 is fixedly connected to the bottom end of the sliding rod 25, and the stop block 27 is fixed to the bottom end of the sliding rod 25, pressing against the ground, keeping the auxiliary device stable during fertilization. A first spring 26 is movably sleeved on the sliding rod 25. The first spring 26 is sleeved on the sliding rod 25, and through its elasticity, it keeps the stop block 27 pressed against the ground, enhancing the stability of the device. One end of the first spring 26 is fixedly connected to the lower surface of the support block 24, and the other end of the first spring 26 is fixedly connected to the stop block 27.

[0032] In this embodiment, when using the farmland fertilization device, fertilizer granules are first poured into the hopper 1. The fertilizer, under the influence of gravity, rotates and flows into the discharge pipe 2, where it is blocked by the second blocking plate 42. Then, holding the handles 12, the fine shovel 21 is inserted into the farmland soil, ensuring it is inserted next to the crops. Next, the positioning rotating plate 28 is pressed against the farmland surface, and the discharge pipe 2 is bent towards the second chute 23, causing the positioning rotating plate 28 to rotate towards the second chute 23. At this time, the taut connecting rope 46 loosens, and the protrusion 44, through the elastic thrust of the second spring 45, pushes the driving plate 4, the first blocking plate 41, and the second blocking plate 42 to move. The end of the first blocking plate 41 away from the driving plate 4 cuts off the inner cavity of the discharge pipe 2, preventing the fertilizer from continuing to flow towards the second blocking plate 42. The second blocking plate 42 also causes the material penetration hole 43 to slide into the discharge pipe 2, so that the fertilizer in the cut discharge pipe 2 flows sequentially from the material penetration hole 43 and the discharge port 3 to the fine shovel 21. Then, as the fine shovel 21 is inserted into the soil and tilted, it will squeeze the soil to create an inclined pit, and the fertilizer flowing into the fine shovel 21 will automatically fall into the inclined pit by gravity. Finally, the fine shovel 21 is directly pulled out of the soil, thus completing the fertilization of the crop quickly, labor-saving and efficient.

[0033] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
