Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a portable corn fertilization device. Background Technology

[0002] Fertilization is a crucial step in ensuring healthy corn growth during cultivation. Corn fertilization typically involves multiple steps, including digging, sowing, applying fertilizer, and covering. Although modern agricultural automation equipment is widely available, relying solely on manual fertilization still consumes a significant amount of time and manpower, leading to low efficiency. However, in some parts of China, especially in geographically limited areas such as forests and mountains, most farmers still choose manual fertilization. Using small fertilizer applicators can improve fertilization efficiency and save labor to some extent.

[0003] The specific operating process is as follows: Growers carry fertilizer storage bags or boxes on their backs, introduce fertilizer into the storage tube through a flexible hose, and then press the control handle to allow the fertilizer to flow out of the tube. Intermittent fertilization is achieved through manual movement. However, due to the relatively simple internal structure of the storage tube, the outflow of fertilizer is difficult to control (i.e., it exhibits a direct flow effect), making quantitative fertilization difficult and failing to meet the requirements of precision fertilization. Therefore, although small fertilizer applicators improve efficiency to some extent, their accuracy and controllability still need improvement. Utility Model Content

[0004] This utility model provides a portable corn fertilization device. By innovatively improving the traditional fertilizer storage pipe, a flow-limiting and material-dispensing impeller is cleverly set at the discharge port. By precisely adjusting the number of rotations of the impeller, the amount of fertilizer discharged can be accurately controlled, thereby achieving the effect of scientific fertilization and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A feeding impeller is rotatably mounted inside the hollow cavity of the fertilizer storage tube, and a drive roller is mounted inside the fertilizer application sleeve. The drive roller is rotatably connected to the feeding impeller. By holding the fertilizer storage tube and pressing it against the ground, the drive roller drives the feeding impeller to rotate, thereby quantitatively controlling the amount of fertilizer discharged from the hollow cavity.

[0007] Preferably, the fertilizer sleeve is nested and slidably installed with the bottom of the fertilizer storage pipe. A sliding column is fixedly provided on the inner top wall of the fertilizer sleeve, and a sliding groove is provided on the side wall of the other end of the fertilizer storage pipe.

A gear is rotatably installed at one end of the drive roller, and the gear meshes with the rack.

[0010] Preferably, the drive roller is provided with an internal gear ring and a drive flywheel inside. The diameter of the drive flywheel is smaller than the diameter of the internal gear ring. One end of the drive flywheel is rotatably connected to the drive roller in the internal gear ring, and the other end of the drive flywheel is fixedly connected to a gear in the internal gear ring.

[0012] Preferably, a transverse short handle is provided on one end sidewall of the fertilizer storage tube, and the transverse short handle is threadedly rotatably connected to the fertilizer storage tube, with anti-slip textures arranged around its sidewall.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] like Figures 1 to 4 As shown, this utility model provides a portable corn fertilization device. The fertilizer storage tube 1 is configured as a long tubular structure with a hollow cavity 2 inside for fertilizer flow. Anti-slip textures 3 are arranged around one end of the side wall of the fertilizer storage tube 1. During use, the anti-slip textures 3 increase friction and provide a stable grip. The anti-slip textures 3 can be filled with rubber material or made concave by cutting grooves. Furthermore, to improve operational adaptability, a horizontal short handle 19 is provided on one end of the side wall of the fertilizer storage tube 1. The horizontal short handle 19 is threadedly connected to the fertilizer storage tube 1 and is detachable to meet different operational needs. Anti-slip textures 3 are also arranged around its side wall to ensure a comfortable grip.

[0022] A flexible hose 4 is connected to the side wall of the other end of the fertilizer storage tube 1. One end of the hose 4 is connected to the hollow cavity 2, and the other end is connected to a fertilizer storage bag or box in the prior art. To achieve quantitative fertilization, a fertilizer sleeve 5 is movably installed at the bottom of the fertilizer storage tube 1. A feeding impeller 6 is rotatably installed inside the hollow cavity 2 of the fertilizer storage tube 1. By driving the rotation of the feeding impeller 6, the fertilizer in the hollow cavity 2 is discharged. By setting the number of rotations of the feeding impeller 6, the flow rate of fertilizer discharged in one rotation can be guaranteed, thereby achieving quantitative fertilization. The driving principle is achieved by installing a drive roller 7 inside the fertilizer sleeve 5. The drive roller 7 is rotatably connected to the feeding impeller 6. In use, by holding the fertilizer storage tube 1 and pressing it onto the ground (i.e., the fertilization area), the drive roller 7 drives the feeding impeller 6 to rotate, thereby discharging the fertilizer in the hollow cavity 2. This operation method is not only flexible, efficient, and easy to operate, but also meets the requirements of precision fertilization.

[0023] Specifically, such as Figure 2 As shown, the fertilizer sleeve 5 is firstly nested and slidably installed with the bottom of the fertilizer storage tube 1. The sliding principle is achieved by the sliding column 8 fixedly installed on the inner top wall of the fertilizer sleeve 5 and the sliding groove 9 installed on the other side wall of the fertilizer storage tube 1. The sliding column 8 and the sliding groove 9 cooperate with each other, so that the sliding column 8 can be slidably installed in the sliding groove 9, thereby achieving the sliding effect.

[0024] Furthermore, to ensure the limiting function of the fertilizer sleeve 5 during sliding, two limiting blocks 18 are also provided on the side wall of the other end of the fertilizer storage tube 1. The two limiting blocks 18 abut against the inner top wall of the fertilizer sleeve 5. When both limiting blocks 18 abut against the inner top wall of the fertilizer sleeve 5, it indicates that the fertilizer sleeve 5 has reached the lowest point of the fertilizer storage tube 1. It should be noted that the length of the internal space of the fertilizer sleeve 5 is its length of movement (i.e., the length from the bottom of the fertilizer storage tube 1 to the bottom of the fertilizer sleeve 5, e.g., ...). Figure 2 The double arrow inside the fertilizer sleeve 5 indicates the number of times the feed impeller 6 rotates. Therefore, by setting the internal space length of the fertilizer sleeve 5, the number of rotations of the feed impeller 6 can be changed, thereby achieving different fertilizer application effects. The specific stroke length can be adjusted or customized according to actual production needs, and will not be limited here.

[0025] The reset of the fertilizer sleeve 5 is achieved by the built-in tension spring 11, such as... Figure 2As shown, an extension block 10 is fixedly installed on the side wall of the other end of the fertilizer storage tube 1. The extension block 10 does not move with the fertilizer sleeve 5, while the sliding column 8 moves with the fertilizer sleeve 5. A tension spring 11 is installed between the sliding column 8 and the extension block, with one end of the tension spring 11 connected to the bottom of the sliding column 8 and the other end connected to the top of the extension block 10. When the fertilizer sleeve 5 is pressed and slides, the tension spring 11 is simultaneously stretched and stores force. After the fertilizer storage tube 1 is lifted, the fertilizer sleeve 5 returns to its original position under the reaction force of the tension spring 11.

[0026] The driving principle of the feeding impeller 6 is as follows: Figure 3 As shown, a rack 12 is fixedly installed on the inner wall of the fertilizer sleeve 5. When the fertilizer sleeve 5 slides, the rack 12 also moves synchronously, while the drive roller 7 only rotates on the fertilizer storage tube 1. The drive roller 7 is installed on the outer side wall of the fertilizer storage tube 1 located inside the fertilizer sleeve 5. One end of the drive roller 7 is rotatably connected to the feed impeller 6 in the hollow cavity 2 via a rotating shaft. Its rotation is achieved by a gear 13 rotatably installed at one end, which meshes with the rack 12. When the rack 12 slides synchronously with the fertilizer sleeve 5, the rack 12 drives the gear 13 to rotate, thereby driving the drive roller 7 to rotate.

[0027] To better control the rotation of drive roller 7 and meet operational requirements, such as Figure 4As shown, an internal gear ring 14 and a drive flywheel 15 are arranged inside the drive roller 7. First, the diameter of the drive flywheel 15 is smaller than the diameter of the internal gear ring 14, so that the drive flywheel 15 can rotate within the internal gear ring 14. The connection characteristic of the drive flywheel 15 is that one end is rotatably connected to the drive roller 7 in the internal gear ring 14, and the other end is fixedly connected to the gear 13 in the internal gear ring 14. Thus, when the gear 13 rotates, the drive flywheel 15 also rotates synchronously, and then the drive flywheel 15 drives the drive roller 7 to rotate. The driving principle of the drive flywheel 15 is achieved by multiple unidirectional pawls 16 rotating on it. The unidirectional pawls 16 are engaged with the internal gear ring 14 and rotate in the same direction. The drive flywheel 15 also has multiple arc-shaped cavities 17 that can accommodate the unidirectional pawls 16. During operation, gear 13 first drives the drive flywheel 15 to rotate. Due to centrifugal force, the unidirectional claw 16, initially stored in the arc-shaped cavity 17, is thrown out and engages with the internal gear ring 14, driving the drive roller 7 to rotate. When the fertilizer sleeve 5 resets and gear 13 rotates in the same direction, it also drives the drive flywheel 15 to rotate in the opposite direction. However, the unidirectional claw 16 on it does not affect the drive roller 7. Due to the reverse rotation effect, the unidirectional claw 16 is stored back in the arc-shaped cavity 17, while the drive roller 7 remains stable, ensuring that the drive roller 7 has only a single set rotation direction. By setting the rotation of the feed impeller 6 in the hollow cavity 2 to have a certain tightness, the feed impeller 6 will not reverse under the influence of fertilizer gravity, thus ensuring the accuracy of final fertilization.

[0028] In summary, this utility model provides a portable corn fertilization device that innovatively improves upon the traditional fertilizer storage tube 1 by cleverly incorporating a flow-limiting and material-distributing impeller 6 at the discharge port. By precisely adjusting the number of rotations of the impeller, the amount of fertilizer discharged can be accurately controlled, thus achieving scientific fertilization. Simultaneously, the ergonomically designed fertilizer sleeve 5 features a simple and ingenious structure, offering convenient and smooth operation: simply pressing the fertilizer storage tube 1 onto the ground allows the fertilizer sleeve 5 to slide smoothly, ensuring quantitative and controllable fertilization. This innovative design not only enhances the enjoyment of manual fertilization, making the operation more labor-saving and efficient, but also significantly improves the accuracy and quality of fertilization, bringing a completely new experience to modern agricultural operations.
