Technical Field

[0001] This utility model relates to the field of fertilizer applicator technology, and in particular to the structure of a fertilizer applicator for precise quantitative fertilization. Background Technology

[0002] A fertilizer applicator is a tool used in agriculture or horticulture to apply fertilizer to the soil or around plants in a specific dosage and manner, which can improve fertilization efficiency and accuracy and reduce the intensity of manual labor.

[0003] The precision quantitative fertilizer applicator mainly includes a fertilizer storage bin, a metering device, a delivery pipeline, and a fertilization component. The metering device controls the amount of fertilizer applied each time. The fertilizer is taken out from the storage bin according to the set dosage, and then the delivery pipeline is used to transport the fertilizer to the fertilization component, and finally it is accurately applied to the target area.

[0004] In existing technologies, some fertilizer applicators rely heavily on the experience and physical strength of operators due to traditional fertilization methods, which involve manual application. This makes it difficult to accurately control the amount of fertilizer applied each time, resulting in uneven fertility in farmland and seriously affecting the uniformity of crop growth and yield stability. Therefore, a fertilizer applicator structure for precise quantitative fertilization is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fertilizer applicator structure for precise quantitative fertilization, aiming to improve the problem of uneven farmland fertility in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The structure of the precision quantitative fertilizer applicator includes a housing and a rod. A fixing ring is fixedly connected to the bottom of the inner wall of the rod. A spring is fixedly connected to the bottom of the inner wall of the fixing ring. A connecting ring is fixedly connected to the top of the spring. A carrier box is fixedly connected to the top of the connecting ring. A cover plate is detachably connected to the bottom of the inner wall of the carrier box. A connecting rod is fixedly connected to the top of the cover plate. A rotating column is rotatably connected to the top of the inner wall of the rod. A baffle is fixedly connected to the top of the carrier box. A fixing box is fixedly connected to the right side of the housing. A fixing component for fixing the fixing strap is provided inside the fixing box.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a first slide groove, a slider is slidably connected inside the first slide groove, a second slide groove is opened inside the slider, a second spring is fixedly connected to the right side of the inner wall of the second slide groove, a trapezoidal block is fixedly connected to the left side of the second spring, a fixing block is fixedly connected to the right side of the housing, i.e. the bottom of the fixing box, and a strap is rotatably connected to the bottom of the fixing block. Multiple fixing holes are opened inside the fixing box and inside the strap.

[0010] As a further description of the above technical solution:

[0011] The outer part of the connecting ring is slidably connected to the inside of the fixed ring, and the outer part of the connecting rod is rotatably connected to the bottom of the rotating column;

[0012] As a further description of the above technical solution:

[0013] The outer side of the carrier box is slidably connected to the top of the fixed ring via the connecting ring. Both the inside of the rod and the inside of the carrier box are provided with feed inlets. The outer side of the baffle is in contact with the inner wall of the rod.

[0014] As a further description of the above technical solution:

[0015] The inner bottom is provided with a discharge port, which is in contact with the bottom of the cover plate;

[0016] As a further description of the above technical solution:

[0017] The outer side of the fixing block is slidably connected to the inside of the fixing box, and the left side of the fixing box is fixedly connected to the right side of the housing;

[0018] As a further description of the above technical solution:

[0019] A connecting pipe is fixedly connected to the front right side of the housing, and the right side of the connecting pipe is fixedly connected to the inner wall of the feed inlet.

[0020] As a further description of the above technical solution:

[0021] The trapezoidal block is slidably connected to the inside of the second groove, and the outside of the trapezoidal block is in contact with the inner wall of the fixing hole.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the fertilizer container is filled with fertilizer, it will descend due to its own weight. It will slide within the fixed ring via the connecting ring, thereby causing the baffle to block the discharge port. The rotating column will then drive the connecting rod and the cover plate to rise, allowing the fertilizer in the container to be discharged from the discharge port. Simultaneously, the connecting ring will compress the first spring during the descent of the container. After fertilization is complete, the elasticity of the first spring will push the connecting ring and the container back to their original positions. This ensures that the amount of fertilizer applied each time is within the container's capacity, improving the accuracy and consistency of fertilizer application, meeting different fertilization needs, reducing human error, and increasing the precision and efficiency of fertilization operations.

[0024] 2. In this utility model, by sliding the slider, the inclined surface of the trapezoidal block is squeezed by the first groove, and then squeezed back into the second groove. At this time, the position of the strap can be adjusted. When the strap moves to the appropriate position, the slider is slid again, and the trapezoidal block will be reset under the elastic action of the second spring and locked into the fixing hole, thereby fixing the strap. This realizes that the position of the strap can be flexibly adjusted according to the comfort of the operator, improving the comfort and convenience of use, and the stability of the fertilizer applicator during use, thus facilitating the smooth progress of fertilization operations.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a fertilizer applicator structure for precise quantitative fertilization, comprising a housing 1 and a rod 2. The housing 1 provides fixation and support for the internal device, and the rod 2 provides fixation and support for the internal quantitative component. A fixing ring 3 is fixedly connected to the bottom of the inner wall of the rod 2. The fixing ring 3 provides fixation and support for a spring 4. The spring 4 has an elastic function and provides elastic support for a connecting ring 5. The connecting ring 5 is fixedly connected to the top of the spring 4. The connecting ring 5 connects the carrier box 6 and the spring 4. The carrier box 6 is fixedly connected to the top of the connecting ring 5 and is used to hold fertilizer.

[0034] The bottom of the inner wall of the carrier box 6 is detachably connected to a cover plate 7, which is used to block the discharge hole. The top of the cover plate 7 is fixedly connected to a connecting rod 8, which is used to pull the cover plate 7 to discharge material. The top of the inner wall of the rod body 2 is rotatably connected to a rotating column 9. Pulling the rotating column 9 causes the connecting rod 8 to rise. The top of the carrier box 6 is fixedly connected to a baffle 10, which is used to block the discharge port. The right side of the housing 1 is fixedly connected to a fixing box 11, which provides fixation and support for the internal fixing components. The inside of the fixing box 11 is provided with fixing components for fixing the fixing strap.

[0035] Reference Figure 1 , Figure 2 and Figure 5The fixing component includes a first slide groove 12, which provides guidance and limiting for the slider 13. The slider 13 is slidably connected inside the first slide groove 12, and the slider 13 provides space for a second slide groove 14. The second slide groove 14 is formed inside the slider 13, and it provides fixing and support for a second spring 15. A second spring 15 is fixedly connected to the right side of the inner wall of the second slide groove 14. The second spring 15 has an elastic function, providing elastic support for the trapezoidal block 16. The left side of the second spring 15 is fixed... A trapezoidal block 16 is fixedly connected to the housing 1, which is used to cooperate with the fixing hole 19 to complete the fixation. A fixing block 17 is fixedly connected to the right side of the housing 1, that is, the bottom of the fixing box 11, to provide fixation and support for the fixing block 17. A strap 18 is rotatably connected to the bottom of the fixing block 17, which makes it easy for the operator to place the housing 1 on their back. Multiple fixing holes 19 are opened inside the fixing box 11 and inside the strap 18. As above, the fixing holes 19 cooperate with the trapezoidal block 16 to complete the fixation.

[0036] Reference Figures 1 to 3 The connecting ring 5 is externally slidably connected to the inside of the fixed ring 3, providing guidance and limiting for the connecting ring 5. The connecting rod 8 is externally rotatably connected to the bottom of the rotating column 9. When the rotating column 9 is pulled, the connecting rod 8 can adapt to the movement of the rotating column 9. The outer part of the carrier box 6 is slidably connected to the top of the fixed ring 3 through the connecting ring 5, providing limiting and guiding for its carrier box 6. Both the inside of the rod body 2 and the inside of the carrier box 6 are provided with feeding ports. The feeding ports are used to cooperate with the connecting pipe 20 to feed the inside of the carrier box 6. The outer part of the baffle 10 is in contact with the inner wall of the rod body 2. When the carrier box 6 descends, it drives the baffle 10 to descend, thereby blocking the feeding port to complete the quantitative feeding. The bottom of the inside of the carrier box 6 is provided with a discharge port, which is used to discharge fertilizer. The discharge port is in contact with the bottom of the cover plate 7. The cover plate 7 is moved by the connecting rod 8, which can be used to place fertilizer for fertilization.

[0037] The external of the fixing block 17 is slidably connected to the inside of the fixing box 11, providing fixation and support for the fixing block 17. The left side of the fixing box 11 is fixedly connected to the right side of the housing 1, providing fixation and support for the fixing box 11. A connecting pipe 20 is fixedly connected to the front right side of the housing 1. The connecting pipe 20 is used to transport fertilizer inside the housing 1. The right side of the connecting pipe 20 is fixedly connected to the inner wall of the feed inlet, transporting the fertilizer inside the connecting pipe 20 to the rod 2 and the carrier box 6. The external of the trapezoidal block 16 is slidably connected to the inside of the second slide groove 14. When the slider 13 slides, the trapezoidal block 16 moves simultaneously and is squeezed by the first slide groove 12, thus retracting into the inside of the second slide groove 14. The external of the trapezoidal block 16 contacts the inner wall of the fixing hole 19, and fixation is completed by the cooperation of the trapezoidal block 16 and the fixing hole 19.

[0038] Working principle: During use, when fertilizer needs to be metered, the container 6, once full of fertilizer, will descend due to its own weight, sliding within the fixed ring 3 via the connecting ring 5. This, in turn, causes the baffle 10 to block the discharge port. When fertilization is needed, pulling the rotating column 9 causes the connecting rod 8 and the cover plate 7 to rise, allowing the fertilizer in the container 6 to be discharged from the discharge port. Simultaneously, the connecting ring 5 compresses the spring 4 during the descent of the container 6. After fertilization, the elasticity of the spring 4 pushes the connecting ring 5 and the container 6 back to their original positions, ensuring that the amount of fertilizer applied each time is within the capacity of the container 6. Through this structure and the elasticity of the spring 4, precise metering of fertilizer is achieved.

[0039] When the strap 18 needs to be adjusted according to the operator's comfort, the inclined surface of the trapezoidal block 16 is squeezed by the first groove 12 by sliding the slider 13, and then squeezed back into the second groove 14. At this time, the position of the strap 18 can be adjusted. When the strap 18 moves to the appropriate position, slide the slider 13 again, and the trapezoidal block 16 will be reset under the elastic action of the second spring 15 and locked into the fixing hole 19, thereby fixing the strap 18. In this way, the housing 1 can be conveniently fixed to the operator's back, meeting the carrying needs during operation and ensuring the stability and convenience of the fertilizer applicator during use.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
