Description

Technical Field

[0001] This utility model relates to the field of fertilizer additive technology, specifically a fertilizer additive device. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production.

[0003] Chinese patent CN222283953U discloses a fertilizer additive device, relating to the field of fertilizer addition technology. The patent includes an additive body with a liquid delivery pipe fixedly connected to its top. A spraying pipe is rotatably connected to the top of the liquid delivery pipe. A spraying assembly is located on the top of the additive body. The spraying assembly includes an impeller, a force-bearing rod, and a sleeve. When rotational spraying is required, the sleeve is moved, causing the force-bearing block to move to the power block. This causes the impeller to rotate, which in turn rotates the first bevel gear (coordinated with the power rod), which in turn rotates the force-bearing rod. The power block then drives the sleeve to rotate, and a belt rotates the spraying pipe. When rotational spraying is not required, the sleeve is reset, preventing the spraying pipe from rotating. This allows for automatic adjustment of the spraying mode, improving the ease of use of the device.

[0004] In the above technical solution, when the force-bearing block of the sleeve does not meet the power block, the spraying pipe is rotatably connected to the infusion pipe and is not fixed, which makes the spraying pipe easy to shake when spraying fertilizer, resulting in poor spraying effect of the device.

[0005] Based on this, the present invention proposes a fertilizer additive. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a fertilizer additive device that can limit the spray pipe in a stationary state through a limiting rack and limiting gear, preventing the spray pipe from shaking during fertilizer spraying and affecting the spraying effect. When the spray pipe needs to rotate, the limiting rack and limiting gear separate, the piston moves out of the fixed box, allowing fertilizer to enter the limiting box, driving the impeller to rotate, thereby driving the spray pipe to rotate and spray, thus improving the practicality of the device.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a fertilizer additive, including a shell, an infusion tube fixedly connected inside the shell, a sleeve rotatably connected to the infusion tube, an impeller and a spraying pipe fixedly connected to the sleeve, and further comprising;

[0008] A limiting gear is fixedly connected to the spray pipe. A limiting rack is slidably connected to the outer shell. The limiting gear meshes with the limiting rack. A connecting pipe is fixedly connected to the infusion pipe. A fixing box is fixedly connected to the connecting pipe. The fixing box is fixedly connected inside the outer shell. A connecting pipe is fixedly connected to the fixing box. A limiting box is fixedly connected to the connecting pipe.

[0009] Preferably, a piston is slidably connected inside the fixed box, and a rack is fixedly connected to the piston.

[0010] Preferably, a protective shell is fixedly connected to the outer shell, and a support plate is fixedly connected to the protective shell.

[0011] Preferably, an electric push rod is fixedly connected to the support plate, and the output shaft of the electric push rod is fixedly connected to a rack.

[0012] Preferably, a rotating column is rotatably connected inside the protective shell, and a drive gear is fixedly connected to the rotating column, with a rack meshing with the drive gear.

[0013] Preferably, a rack two is slidably connected inside the housing, the rack two meshes with the drive gear, and the rack two is fixedly connected to the limiting rack.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, in this utility model, the combination of rack one, rotating column, drive gear, rack two, limiting rack and limiting gear ensures that the spray pipe is fixed during fixed-point spraying, thus preventing the spray pipe from shaking during fertilizer spraying and affecting the spraying effect.

[0016] Secondly, in this utility model, when it is necessary to rotate the sprayer, the electric push rod is activated, which drives the rack and piston to move upward, allowing the fertilizer to enter the limiting box and drive the impeller to rotate. At the same time, the limiting rack moves away from the limiting gear under the action of the drive gear and the rack, so that the limiting rack and the limiting gear are no longer meshed. The spray pipe can rotate with the rotation of the impeller, which allows the device to quickly switch the spraying state and improves the practicality of the device. Attached Figure Description

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved fertilizer additive. The technical solution of this utility model is as follows:

[0026] like Figures 1-4 As shown, a fertilizer additive includes a housing 1, an infusion pipe 2 fixedly connected inside the housing 1, the infusion pipe 2 being connected to the output end of a pump, the pump drawing fertilizer from inside the housing 1 into the infusion pipe 2, and incidentally spraying the fertilizer from the infusion pipe 2 and the spray pipe 5, a sleeve 3 being rotatably connected to the infusion pipe 2, an impeller 4 and the spray pipe 5 being fixedly connected to the sleeve 3, and also includes;

[0027] A limiting gear 19 is fixedly connected to the spray pipe 5. A limiting rack 18 is slidably connected to the outer shell 1. The limiting gear 19 meshes with the limiting rack 18. The limiting gear 19 and the limiting rack 18 work together to limit the spray pipe 5, preventing the spray pipe 5 from shaking during the fixed-point spraying of fertilizer and affecting the spraying effect. A connecting pipe 1 6 is fixedly connected to the infusion pipe 2. A fixing box 7 is fixedly connected to the connecting pipe 1 6. The fixing box 7 is fixedly connected to the outer shell 1. A connecting pipe 2 8 is fixedly connected to the fixing box 7. A limiting box 9 is fixedly connected to the connecting pipe 2 8. When the fertilizer enters the limiting box 9 through the connecting pipe 2 8, it will hit the impeller 4, thereby pushing the impeller 4 to rotate, causing the spray pipe 5 to rotate, thus realizing rotational spraying.

[0028] Furthermore, such as Figure 3 and Figure 4As shown, a piston 10 is slidably connected inside the fixed box 7, and a rack 14 is fixedly connected to the piston 10. In the fixed-point spraying state, the piston 10 is located inside the fixed box 7, blocking the connecting pipe 6, so that the fertilizer cannot enter the fixed box 7 through the connecting pipe 6.

[0029] Furthermore, such as Figures 1-4 As shown, a protective shell 11 is fixedly connected to the outer shell 1. The protective shell 11 encloses the drive gear 16, rack 17, limiting rack 18 and limiting gear 19, thereby achieving the effect of dust protection. A support plate 12 is fixedly connected to the protective shell 11. The cross-section of the support plate 12 is "L".

[0030] Furthermore, such as Figures 1-4 As shown, an electric push rod 13 is fixed to the support plate 12 by bolts. The output shaft of the electric push rod 13 is fixed to the rack 14 by bolts. The electric push rod 13 drives the rack 14 to move, thereby controlling the movement of the piston 10.

[0031] Furthermore, such as Figure 4 As shown, a rotating column 15 is rotatably connected inside the protective shell 11, and a drive gear 16 is fixedly connected to the rotating column 15. A rack 14 meshes with the drive gear 16, and the drive gear 16 is driven to rotate by the movement of the rack 14.

[0032] Furthermore, such as Figure 4 As shown, a rack 17 is slidably connected inside the outer casing 1. The rack 17 meshes with the drive gear 16 and is fixedly connected to the limiting rack 18. When the device switches from fixed-point spraying to rotary spraying, the rack 14 moves upward, causing the drive gear 16 to rotate, which in turn drives the rack 17 to move, causing the limiting rack 18 to move accordingly. This separates the limiting rack 18 from the limiting gear 19, releasing the limitation on the spray pipe 5, allowing the spray pipe 5 to rotate with the impeller 4.

[0033] The specific working method is as follows: During fixed-point spraying, the limiting gear 19 meshes with the limiting rack 18 to fix the spray pipe 5, preventing the spray pipe 5 from shaking during fertilizer spraying and affecting the spraying effect. When rotation spraying is required, the electric push rod 13 is activated, and its output shaft pulls the rack 14 upward, causing the piston 10 to move upward as well. The piston 10 moves out of the fixed box 7, no longer blocking the connecting pipe 6, allowing the fertilizer to enter the fixed box 7 through the connecting pipe 6, then enter the connecting pipe 8 through the fixed box 7, and finally enter the limiting box 9. Inside, the flowing fertilizer drives the impeller 4 to rotate. As rack 14 moves upward, the drive gear 16 meshes with rack 14, and the drive gear 16 meshes with rack 17. Therefore, the drive gear 16 rotates with the movement of rack 14, driving rack 17 to move. This causes the limiting rack 18 to move away from the limiting gear 19, and the limiting rack 18 and the limiting gear 19 no longer mesh. At this time, the spray pipe 5 is released from restriction and can rotate with the rotation of the impeller 4, thereby realizing rotational spraying.

[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
