Description

Technical Field

[0001] This utility model relates to fertilization tools, and more particularly to an air-blowing anti-clogging fertilization device for fruit and vegetable seedlings. Background Technology

[0002] Currently, when applying granular fertilizers such as urea and compound fertilizer to individual fruit and vegetable seedlings, fertilizer application tools such as fertilizer guns are often used to improve fertilizer utilization efficiency, ensure fertilizer effectiveness, and prevent fertilizer from being washed away by rainwater. The tool is inserted into the soil around the seedling, and then the urea or compound fertilizer is placed into the tool and falls into the soil through the outlet hole at the inserted end. The tool is then pulled out of the soil to complete the fertilization. However, when using these tools, the soil sometimes blocks the outlet hole, preventing the urea or compound fertilizer from falling smoothly into the soil, thus affecting soil fertilization of the fruit and vegetable seedlings. Utility Model Content

Below the connecting seat is a cone-shaped fertilizer head with the cone tip pointing downwards. There is a gap between the top end of the fertilizer head and the bottom end of the connecting seat, and the outer diameter of the top end of the fertilizer head is larger than the outer diameter of the connecting seat. Fertilization holes communicating with the cavity of the fertilizer tube are distributed on the connecting seat.

[0004] As a preferred technical solution, the air intake control device includes an air intake pipe connected between an air storage container and an air intake port, an air intake valve provided on the air intake pipe, an air intake lever connected between the air intake valve and a control handle, and an air intake return spring provided between the air intake lever and the bracket.

[0005] As a preferred technical solution, the bottom of the hopper is provided with a fertilizer outlet, the fertilizer inlet pipe is connected to the fertilizer outlet, a fertilizer discharge roller is rotatably provided at the fertilizer outlet, the edge of the fertilizer outlet is tightly attached to the fertilizer discharge roller, a plurality of fertilizer discharge grooves are provided in the circumferential recess on the outer circumferential surface of the fertilizer discharge roller, one end of the fertilizer discharge roller extends out of the fertilizer inlet pipe and is provided with a ratchet, the control handle is hinged to a fertilizer application lever, the fertilizer application lever slides through a sliding hole on the bracket near the ratchet end, and a pawl that engages with the ratchet teeth on the ratchet is connected to the fertilizer application lever by a pin, a drive spring is provided between the pawl and the fertilizer application lever to press the pawl against the ratchet, and a fertilizer return spring is provided between the fertilizer application lever and the bracket.

[0006] As a preferred technical solution, the top center of the connecting seat is provided with a material distribution protrusion, and the fertilizer holes are distributed around the material distribution protrusion.

[0007] As a preferred technical solution, the top of the fertilizer pipe is closed, the air inlet is higher than the opening of the fertilizer inlet pipe inside the fertilizer pipe, and the opening of the air inlet on the inner wall of the fertilizer pipe is inclined downward tangentially.

[0008] The air-blowing anti-clogging fertilizer application device for fruit and vegetable seedlings, which adopts the above-mentioned technical solution, includes a fertilizer application pipe. An air storage container is mounted on the top of the fertilizer application pipe via a bracket. The air storage container is connected to an air compression device. An air inlet is provided on the fertilizer application pipe. An air intake control device is provided between the air storage container and the air inlet. A control handle is hinged to the bracket, and the control handle connects to and controls the air intake control device. A hopper is also provided on the bracket, and the hopper is connected to the fertilizer application pipe via a fertilizer inlet pipe. A connecting seat for sealing the bottom opening of the fertilizer application pipe is detachably fixed to the bottom of the fertilizer application pipe. A cone-shaped fertilizer application head with a downward-pointing tip is connected below the connecting seat. A gap is left between the top of the fertilizer application head and the bottom of the connecting seat, and the outer diameter of the top of the fertilizer application head is larger than the outer diameter of the connecting seat. Fertilization holes communicating with the cavity of the fertilizer application pipe are distributed on the connecting seat. In use, this invention provides high-pressure air to the air storage container via an air compressor. The fertilizer applicator is inserted into the soil near the fruit and vegetable seedlings. Granular fertilizers such as urea and compound fertilizer are added to the hopper. The fertilizer particles enter the fertilizer tube and fall into the fertilizer hole at the bottom of the connecting seat. The control handle controls the air intake control device to blow high-pressure airflow from the air storage container into the fertilizer tube. Because there is a gap between the top of the fertilizer applicator and the bottom of the connecting seat, and the outer diameter of the top of the fertilizer applicator is larger than the outer diameter of the connecting seat, the gap between the top of the fertilizer applicator and the bottom of the connecting seat is small after insertion into the soil. The space between the fertilizer nozzles contains less and loose soil, which allows the high-pressure airflow to easily blow fertilizer particles from the fertilizer nozzles into the space between the top of the fertilizer head and the bottom of the connector. At the same time, the soil blocking the fertilizer nozzles is also blown out. After the fertilizer head is lifted out of the soil, fertilizers such as urea and compound fertilizer remain in the soil near the fruit and vegetable seedlings, preventing the fertilizer outlet of the fertilizer device from becoming blocked and ensuring normal fertilization. In addition, the high-pressure airflow will also blow off the fertilizer particles adhering to the inner wall of the fertilizer tube, so that the inner wall of the fertilizer tube is no longer covered with fertilizer particles.

Detailed Implementation

[0011] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0012] like Figure 1 and 2 As shown, the air-blowing anti-clogging fertilizer application device for fruit and vegetable seedlings includes a fertilizer pipe 1. An air storage container 3 is mounted on the top of the fertilizer pipe 1 via a bracket 2. The air storage container 3 is connected to an air compressor 4. Typically, the fertilizer pipe 1 is made of metal, and the bracket 2 can be made of welded flat metal strips to minimize weight while maintaining strength. The bracket 2 and fertilizer pipe 1 can be welded together. The air storage container 3 can be a high-pressure air cylinder made of plastic, and the air compressor 4 can be a manual pump mechanism, such as the pump mechanism of a common backpack manual sprayer. An air inlet is provided on the fertilizer pipe 1, and an air intake control device is provided between the air storage container 3 and the air inlet. A control handle 6 is hinged to the bracket 2, and the control handle 6 connects to and controls the air intake control device. The support 2 is also equipped with a hopper 7, which is connected to the fertilizer application pipe 1 through a fertilizer inlet pipe 8. A lifting handle 5 can be set on the support 2, and a control handle 6 can be hinged to the lifting handle 5. A return torsion spring is set between the control handle 6 and the lifting handle 5 to facilitate the use of the entire fertilizer application device and the operation of the control handle 6.

[0013] like Figure 1 and 4As shown, the bottom end of the fertilizer pipe 1 is detachably and fixedly connected to a connecting seat 9 for sealing the bottom opening of the fertilizer pipe 1. The detachable and fixed connection between the connecting seat 9 and the bottom opening of the fertilizer pipe 1 facilitates cleaning inside the fertilizer pipe 1. A cone-shaped fertilizer head 10 with the cone tip pointing downwards is connected below the connecting seat 9. There is a gap between the top end of the fertilizer head 10 and the bottom end of the connecting seat 9, and the outer diameter of the top end of the fertilizer head 10 is larger than the outer diameter of the connecting seat 9. Fertilization holes 11 that communicate with the cavity of the fertilizer pipe 1 are distributed on the connecting seat 9. The conical fertilizer head 10 facilitates the smooth insertion of the fertilizer applicator into the soil surrounding the seedlings. A gap is maintained between the top of the fertilizer head 10 and the bottom of the connecting seat 9, and the outer diameter of the fertilizer head 10's top is larger than that of the connecting seat 9. This results in less soil and looser soil in the space between the fertilizer head 10's top and the connecting seat 9 after insertion, allowing the high-pressure airflow to blow fertilizer particles from the fertilizer hole 11 into this space, while also reducing the likelihood of soil clogging the fertilizer hole 11. Furthermore, to facilitate the insertion of the fertilizer head 10 into the soil, a foot pedal 12 can be installed on the lower outer wall of the fertilizer tube 1 for foot assistance during insertion. Fertilizer can be manually added to the hopper 7 when the fertilizer head 10 is inserted into the soil near the seedlings, or alternatively, fertilizer can be added to the hopper 7 first, and then a controlled amount can be added into the fertilizer tube 1 when the fertilizer head 10 is inserted into the soil near the seedlings.

[0014] like Figure 2 and 3 As shown, the air intake control device includes an air intake pipe 13 connected between the air storage container 3 and the air intake port. An air intake valve 14 is installed on the air intake pipe 13. An air intake lever 15 is connected between the air intake valve 14 and the control handle 6. An air intake return spring 16 is installed between the air intake lever 15 and the bracket 2. The air intake valve 14 can be a pull-type on / off valve that controls the opening and closing of the air passage. By manipulating the control handle 6, the air intake lever 15 pulls the valve stem of the air intake valve 14 to open the air intake valve 14, allowing the high-pressure gas in the air storage container 3 to be blown at high speed into the fertilizer pipe 1 through the air intake pipe 13 and the air intake valve 14 from the air intake port. Afterwards, the control handle 6 is released, and under the action of the air intake return spring 16, the control handle 6 and the air intake lever 15 return to their original positions, and the air intake valve 14 returns to its closed position.

[0015] like Figure 3 and 5As shown, the bottom of the hopper 7 is provided with a fertilizer outlet 17, and the fertilizer inlet pipe 8 is connected to the fertilizer outlet 17. A fertilizer outlet roller 18 is rotatably installed at the fertilizer outlet 17. The edge of the fertilizer outlet 17 is tightly fitted to the fertilizer outlet roller 18. An elastic rubber plate 19 can be installed around the fertilizer outlet 17. The rubber plate 19 is tightly fitted to the surface of the fertilizer outlet roller 18 to ensure that the fertilizer particles in the hopper 7 do not leak out from the gaps around the fertilizer outlet roller 18. Several circumferentially recessed grooves are provided on the outer circumferential surface of the fertilizer outlet roller 18. The fertilizer outlet trough 20 has one end of the fertilizer outlet roller 18 extending out of the fertilizer inlet pipe 8 and equipped with a ratchet 21. The control handle 6 is hinged to a fertilizer application lever 23. The fertilizer application lever 23 slides through a sliding hole on the bracket 2 near the end of the ratchet 21. A pawl 22 that engages with the ratchet teeth on the ratchet 21 is connected to the fertilizer application lever 23 by a pin. A driving spring is provided between the pawl 22 and the fertilizer application lever 23 to press the pawl 22 against the ratchet 21. A fertilizer return spring 25 is provided between the fertilizer application lever 23 and the bracket 2. The control handle 6 pulls the fertilizer application lever 23, which drives the pawl 22 to rotate the ratchet 21 and the fertilizer discharge roller 18. During use, fertilizers such as urea and compound fertilizer are added to the hopper 7. The fertilizer fills the fertilizer discharge slot 20 in the hopper 7. By manipulating the control handle 6, the fertilizer application lever 23 drives the pawl 22 to rotate the ratchet 21 and the fertilizer discharge roller 18. The fertilizer discharge slot 20, which is filled with fertilizer, rotates out of the hopper 7 and enters the fertilizer inlet pipe 8. The fertilizer falls from the fertilizer discharge slot 20 into the fertilizer inlet pipe 8 and into the fertilizer application pipe 1. Then, under the action of the fertilizer return spring 25, the fertilizer application lever 23 returns to its original position, and the fertilizer discharge slot 20 in the hopper 7 on the fertilizer discharge roller 18 is refilled, waiting for the next fertilization. Furthermore, to prevent the fertilizer from accumulating too densely at the fertilizer outlet 17, which would make it difficult to fill the fertilizer outlet 20, an elastic plate 26 can be installed on the inner wall of the hopper 7, with its end extending into the fertilizer outlet 20. In this way, the outer circumference of the fertilizer outlet roller 18 and each recessed fertilizer outlet 20 will repeatedly move the elastic plate 26, causing the elastic plate 26 to vibrate and return to its original position, thereby vibrating and stirring the fertilizer at the fertilizer outlet 17 and preventing the fertilizer from accumulating too densely at the fertilizer outlet 17, which would make it difficult to fill the fertilizer outlet 20.

[0016] like Figure 1 and 4 As shown, a material distribution protrusion 27 is provided at the top center of the connecting seat 9, and the fertilizer holes 11 are distributed around the material distribution protrusion 27. In this way, after the fertilizer falls to the bottom of the fertilizer tube 1 under the action of the material distribution protrusion 27, it will not accumulate in the middle. The airflow will also be guided to the fertilizer holes 11 on the periphery under the action of the material distribution protrusion 27, thereby improving the air blowing effect.

[0017] like Figure 2 and 3As shown, the top of the fertilizer pipe 1 is closed, which can improve the sealing performance of the fertilizer pipe 1. The air inlet is higher than the opening of the fertilizer inlet pipe 8 inside the fertilizer pipe 1, so that the airflow can accelerate the falling of fertilizer at the opening of the fertilizer inlet pipe 8 inside the fertilizer pipe 1, and at the same time, it can blow away and clean the fertilizer adhering to the opening of the fertilizer inlet pipe 8 inside the fertilizer pipe 1, ensuring that the fertilizer enters the fertilizer pipe 1 smoothly. The opening of the air inlet on the inner wall of the fertilizer pipe 1 is tangentially inclined downward, so that the airflow will blow downward spirally along the inner wall of the fertilizer pipe 1, improving the cleaning effect on the inner wall of the fertilizer pipe 1 and preventing fertilizer from adhering to the inner wall of the fertilizer pipe 1.

[0018] In this invention, a storage battery can also be installed on the bracket 2, and the air inlet valve 14 can be an electrically controlled solenoid valve, and the fertilizer outlet roller 18 can be driven by a motor. The storage battery provides power to the electrically controlled solenoid valve and the motor, and a control button is provided on the handle for convenient control.

[0019] In use, this invention provides high-pressure air to the air storage container 3 via the air compressor 4. Urea, compound fertilizer, and other fertilizers are added to the hopper 7, filling the fertilizer outlet 20 within the hopper 7. The fertilizer applicator 10 is inserted into the soil near the fruit and vegetable seedlings. The control handle 6 is operated to pull the fertilizer applicator lever 23 and the air intake lever 15. The fertilizer applicator lever 23 drives the pawl 22, which in turn drives the ratchet 21 and the fertilizer outlet roller 18 to rotate. The fertilizer outlet 20, now filled with fertilizer, rotates out of the hopper 7 and into the fertilizer inlet pipe 8. The fertilizer falls from the outlet 20 into the fertilizer inlet pipe 8 and then into the fertilizer applicator pipe 1. Simultaneously, the air intake lever 15 pulls the valve stem of the air intake valve 14, opening the air intake valve 14. The high-pressure gas in the gas storage container 3 is blown into the fertilizer pipe 1 at high speed through the air inlet through the air inlet pipe 13 and the air inlet valve 14. The high-pressure airflow blows the fertilizer particles out from the fertilizer hole 11 and into the space between the top of the fertilizer head 10 and the bottom of the connecting seat 9. At the same time, the soil blocking the fertilizer hole 11 is also blown out. Then, the control handle 6 is released. Under the action of the air inlet return spring 16 and the fertilizer return spring 25, the control handle 6, the fertilizer pull rod 23, and the air inlet pull rod 15 return to their original positions, and the air inlet valve 14 returns to its original position and closes. Then, the fertilizer head 10 is lifted out of the soil, and the fertilizer outlet trough 20 located in the hopper 7 on the fertilizer outlet roller 18 is refilled for the next fertilization.
