Description

Technical Field

[0001] This utility model relates to the field of fertilization device technology, and in particular to a multi-mode integrated backpack variable fertilization device. Background Technology

[0002] In current agricultural production, fertilization of many crops, including flue-cured tobacco, generally relies on traditional manual methods. This method requires operators to bend over for long periods of time, manually applying fertilizer to the crop roots or into the soil.

[0003] This operational mode is not only extremely labor-intensive, leading to operator fatigue, but also inefficient in fertilization, making it difficult to meet the needs of large-scale planting. More importantly, crops have specific requirements for fertilization methods at different growth stages. Taking flue-cured tobacco as an example, during the transplanting period, ring fertilization is usually required to avoid direct contact between fertilizer and seedlings; during the growing season, deep burial of fertilizer in holes may be necessary; and at other stages, strip fertilization may be suitable.

[0004] However, existing fertilization tools are generally limited in function and lack the ability to easily switch between multiple fertilization modes. A single device typically only performs one fertilization method, such as a single broadcast or spot applicator, and cannot be flexibly adjusted according to the actual needs of crops at different growth stages. This forces growers to either frequently change different specialized tools, significantly increasing costs and operational complexity, or compromise by using suboptimal fertilization methods, affecting fertilization effectiveness and crop yield.

[0005] Therefore, there is an urgent need for a multi-mode integrated backpack variable fertilizer application device to solve the above-mentioned technical pain points. Utility Model Content

[0048] Optionally, two carrying straps are installed on the outer wall of the fertilizer storage tank 1.

[0049] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the strip fertilizer application device 4 has a tubular outlet, which can directly apply fertilizer near the crop roots and is suitable for root fertilization of most crops. The strip fertilizer application device 4 includes a strip fertilizer delivery pipe 402, a strip application sleeve 403, a strip fertilizer outlet 404, a strip application regulator 408, and a strip application baffle 409. The first end of the strip fertilizer delivery pipe 402 is detachably connected to the second end of the fertilizer delivery hose 3. The strip application sleeve 403 is installed at the second end of the strip fertilizer delivery pipe 402. The axis of the strip fertilizer outlet 404 is set at an angle to the axis of the strip application sleeve 403. The strip application regulator 408 is installed inside the strip fertilizer outlet 404. The strip application regulator 408 has a material passage and a chute. The chute extends along the axial direction of the strip fertilizer delivery pipe 402. The strip application baffle 409 is slidably connected in the chute. The strip application baffle 409 slides along the axial direction of the strip fertilizer delivery pipe 402 to block or guide the material passage.

[0050] Furthermore, the strip application fertilizer dispensing device 4 also includes a strip application spring tube 405, a strip application spring 406, a strip application slider 407, and a pull rope 8. The strip application spring tube 405 is installed on the outer wall of the strip application sleeve 403, and one end of the strip application spring tube 405 is connected to the strip application fertilizer outlet 404. The strip application spring 406 and the strip application slider 407 are both installed inside the strip application spring tube 405. The strip application slider 407 is connected to the strip application baffle 409. One end of the strip application spring 406 is connected to the side of the strip application slider 407 facing away from the strip application baffle 409, and the other end is connected to the strip application spring tube 405.

The pull rope 8 extends out of one end of the strip application spring tube 405 and is connected to the trigger handle 7.

[0052] When using the strip application fertilizer device 4, by holding the trigger handle 7 and pulling the pull rope 8, the strip application slider 407 slides towards the side closer to the fertilizer delivery hose 3, which in turn drives the strip application baffle 409 to slide towards the side closer to the fertilizer delivery hose 3, thus opening the material passage of the strip application regulator 408. After fertilization is completed, the trigger handle 7 is released, and the strip application spring 406 pushes the strip application slider 407 and the strip application baffle 409 to reset, covering the material passage of the strip application regulator 408.

[0053] Optionally, such as Figure 1 , Figure 5 and Figure 6 As shown, during the tobacco growing season, a hole-applying fertilizer device is used, which inserts the fertilizer inlet directly into the soil to apply fertilizer. This not only applies fertilizer directly into the soil but also reduces the need for covering it with soil. The hole-applying fertilizer device includes a hole-applying fertilizer delivery pipe 502, a hole-applying fertilizer outlet pipe 503, a hole-applying shovel 504, a hole-applying regulator 508, and a hole-applying regulating ball 509.

The hole-applying regulating ball 509 is set inside the conical channel. The diameter of the hole-applying regulating ball 509 is larger than the bottom diameter of the conical channel. The hole-applying regulating ball 509 can block or open the conical channel.

[0054] Furthermore, the hole-applying fertilizer device also includes a hole-applying handle 501, a hole-applying spring tube 505, a hole-applying spring 506, a hole-applying slider 507, a trigger handle 7, and a pull rope 8. The hole-applying spring tube 505 is installed at an angle downwards on the hole-applying fertilizer pipe 503. The hole-applying spring 506 and the hole-applying slider 507 are both installed inside the hole-applying spring tube 505. The hole-applying slider 507 is connected to the hole-applying adjusting ball 509. One end of the hole-applying spring 506 is connected to the side of the hole-applying slider 507 facing away from the hole-applying adjusting ball 509, and the other end is connected to the hole-applying spring tube 505. The hole-applying handle 501 is installed on the hole-applying fertilizer delivery pipe 502. The trigger handle 7 passes through the hole-applying handle 501 and is installed on the hole-applying fertilizer delivery pipe 502. One end of the pull rope 8 is connected to the trigger handle 7, and the other end is connected to the hole-applying slider 507.

[0055] When using the fertilization device, the pull rope 8 is pulled by holding the trigger handle 7, causing the fertilization slider 507 to slide upward. The fertilization slider 507 drives the fertilization regulating ball 509 to rise, opening the conical channel of the fertilization regulator 508. After fertilization is completed, the trigger handle 7 is released, and the fertilization spring 506 pushes the fertilization slider 507 to reset. After the fertilization slider 507 resets, the fertilization regulating ball 509 descends into the conical channel of the fertilization regulator 508 through gravitational potential energy, blocking the conical channel.

[0056] Optionally, such as Figure 1 , Figure 7 and Figure 8 As shown, the ring-shaped fertilizer application device is suitable for use during tobacco transplanting. By designing the fertilizer inlet in a ring shape, the tobacco seedlings are covered inside the ring during fertilization. This can prevent fertilizer from being applied to the seedlings and thus avoid burning them. The ring-applying fertilizer dispensing device includes a ring-applying fertilizer delivery pipe 602, a ring-applying discharge pipe 603, a ring-applying outer sleeve 604, a ring-applying inner baffle 605, a ring-applying regulator 609, and a ring-applying regulating ball 610. The first end of the ring-applying fertilizer delivery pipe 602 is detachably connected to the second end of the fertilizer delivery hose 3. The first end of the ring-applying discharge pipe 603 is installed at the second end of the ring-applying fertilizer delivery pipe 602. The ring-applying outer sleeve 604 is connected to the second end of the ring-applying discharge pipe 603. The ring-applying inner baffle 605 is installed inside the ring-applying outer sleeve 604, and a material drop space is formed between the ring-applying inner baffle 605 and the ring-applying outer sleeve 604. The ring-applying regulator 609 is installed inside the ring-applying discharge pipe 603. The ring-applying regulator 609 has a conical channel. The ring-applying regulating ball 610 is set inside the conical channel and can block or open the conical channel.

[0057] Furthermore, the ring fertilizer application device also includes a trigger handle 7, a pull rope 8, a ring application grip 601, a ring application spring tube 606, a ring application spring 607, and a ring application slider 608. The ring application spring tube 606 is installed inclined downwards on the ring application discharge pipe 603. The ring application spring 607 and the ring application slider 608 are both installed inside the ring application spring tube 606. The ring application slider 608 is connected to the ring application adjusting ball 610. One end of the ring application spring 607 is connected to the side of the ring application slider 608 facing away from the ring application adjusting ball 610, and the other end is connected to the ring application spring tube 606. The ring application grip 601 is installed on the ring application fertilizer delivery pipe 602. The trigger handle 7 passes through the ring application grip 601 and is installed on the ring application fertilizer delivery pipe 602. One end of the pull rope 8 is connected to the trigger handle 7, and the other end is connected to the ring application slider 608.

[0058] When using the ring-applying fertilizer device, by holding the trigger handle 7 and pulling the rope 8, the ring-applying slider 608 slides upward. The ring-applying slider 608 drives the ring-applying regulating ball 610 to rise, opening the conical channel of the ring-applying regulator 609, and the fertilizer slides down between the inner ring-applying stop 605 and the outer ring-applying stop 604. After fertilization is completed, the trigger handle 7 is released, the ring-applying spring 607 pushes the ring-applying slider 608 to return to its original position, and the ring-applying regulating ball 610 descends into the conical channel of the ring-applying regulator 609 through gravitational potential energy, blocking the conical channel.
