Description

Technical Field

[0001] This utility model relates to the field of fertilization equipment technology, specifically to a portable corn fertilization device that can be inserted into the soil for fertilization. Background Technology

[0002] When planting corn, fertilization is necessary to ensure its vigorous growth and increase yield. In mountainous areas or areas with small planting areas, fertilizer is usually applied manually by hand, then scattered across the entire field, allowing it to gradually nourish the corn roots through soil penetration and diffusion. However, this method of fertilization often results in uneven application due to the random placement of fertilizer during manual application, leading to missed areas and overlapping application.

[0003] In the prior art, such as Chinese Utility Model Application No. 202420103788.8, a corn planting fertilization device is specifically disclosed, including a fertilizer pipe, the bottom of which is slidably inserted into a sleeve. Both the fertilizer pipe and the sleeve have discharge ports on their outer walls, arranged vertically. A flow guide is fixed to the inner wall of the fertilizer pipe and corresponds to the discharge port on the fertilizer pipe. Two ends of an elastic compression component are connected to the outer walls of the fertilizer pipe and the sleeve, respectively. The bottom of the handle is connected to the top of the fertilizer pipe via a T-connector, and the fertilizer box is connected to the T-connector via a flexible hose. Fertilizer in the fertilizer box enters the fertilizer pipe sequentially through the flexible hose and the T-connector, accumulating on the flow guide. When the operator quickly presses the handle, the discharge port on the fertilizer pipe coincides with the discharge port on the sleeve, causing the fertilizer accumulated inside the fertilizer pipe to flow out sequentially through the discharge ports on the fertilizer pipe and the sleeve, thereby improving the uniformity of the fertilizer application. However, when applying fertilizer using this patent, the fertilizer is still piled up on the ground at fixed points. The fertilizer cannot quickly penetrate into the soil and will evaporate due to sunlight, making it difficult for the corn roots to fully absorb it, resulting in low fertilizer utilization. Summary of the Invention

The driving end of the second lever is movably connected to the lower middle part of the first lever, and the driven end of the second lever is movably connected to the limiting assembly. One end of the limiting assembly is fixedly connected to the outer wall of the storage tube, and a limiting part is provided on the side away from the storage tube. The driven end of the second lever is movably connected to the limiting part so that the driven end of the second lever slides in the limiting part. The shovel head is fixedly connected to the side wall of the second lever through a connecting rod so that when the second lever slides along the limiting part, it drives the shovel head to move, thereby realizing digging.

[0009] Preferably, the digging mechanism further includes a reset spring; one end of the reset spring is fixedly connected to the outer wall of the storage tube, and the other end is fixedly connected to the upper part of the first lever.

[0010] Preferably, a piston switch is provided inside the storage tube, which fits against the inner wall of the storage tube to control the amount of material discharged from the storage tube; the piston switch includes a storage part, a connecting part, and a spring; the upper part of the storage part is higher than the upper end of the discharge port on the side wall of the storage tube, the connecting part is located on the lower side of the storage part, one end of the spring is fixedly located at the bottom of the storage part, and the other end is fixedly connected to the bottom of the storage tube; a rectangular opening is opened on the side of the storage tube facing the digging mechanism, and the connecting part of the piston switch passes through the rectangular opening and rests on the upper part of the first lever.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In use, this invention involves first loading an appropriate amount of fertilizer into a storage box. The fertilizer then passes through a conveying pipe and a supporting mechanism, eventually accumulating in the storage pipe. The base is placed on the land where fertilization is needed. The digging mechanism is then activated to dig a hole. During digging, the fertilizer from the storage pipe enters the discharging mechanism and is discharged from its outlet into the hole dug by the digging mechanism. Releasing the digging mechanism covers the fertilizer with soil, achieving soil-buried fertilization. This method reduces direct contact between the fertilizer and the atmosphere, effectively preventing fertilizer volatilization and extending the fertilizer's time in the soil, thus increasing its sustained effectiveness and preventing nutrient deficiency in crops later in the season. Simultaneously, soil-buried fertilization promotes the adsorption of fertilizer by soil ions, thereby improving fertilizer utilization. Furthermore, soil-buried fertilization places the fertilizer in the soil surrounding the crop roots, a location conducive to root absorption. Since the root system of most crops is mainly distributed in the soil at a depth of 8-15 cm, burying fertilizer in the soil can make the fertility around the roots more vigorous. In addition, the deeper soil layer is relatively moist, which further promotes the roots' absorption of nutrients. Furthermore, burying fertilizer in the soil can also encourage the roots to grow deeper. The fertilizer below the roots will induce the roots to grow towards the fertilizer, and it can also promote the development of more fibrous roots and stabilize the root system.

Detailed Implementation

[0028] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figure 1 A portable corn fertilization device for soil application includes: a storage box 100, a conveying pipe 200, a support mechanism 300, a storage pipe 400, a base 500, a digging mechanism 600, and a discharging mechanism 700. The discharge port of the storage box 100 is connected to the conveying pipe 200. One end of the support mechanism 300 is connected to the conveying pipe 200, and the other end is connected to the storage pipe 400, so that the fertilizer in the storage box 100 enters the storage pipe 400 for application via the conveying pipe 200 and the support mechanism 300. The base 500 and the digging mechanism 600 are both connected to the outer wall of the storage pipe 400, and the base 500 and the digging mechanism 600 are arranged opposite to each other. The discharging mechanism 700 is connected to the discharge port on the side wall of the storage pipe 400, and the application port of the discharging mechanism 700 is located between the base 500 and the digging mechanism 600, so that the fertilizer falls into the pit dug by the digging mechanism 600.

[0030] In use, this invention involves first loading an appropriate amount of fertilizer into the storage box 100. The fertilizer in the storage box 100 then flows through the conveying pipe 200 and the supporting mechanism 300, eventually accumulating in the storage pipe 400. The base 500 is placed on the soil near the corn to be fertilized. The digging mechanism 600 is then activated to dig a hole. During digging, the fertilizer in the storage pipe 400 enters the discharging mechanism 700 and is discharged from its application port, falling into the hole dug by the digging mechanism 600. Releasing the digging mechanism 600 allows soil to cover the fertilizer, achieving soil-burying fertilization. This method reduces direct contact between the fertilizer and the atmosphere, effectively preventing fertilizer volatilization and extending the fertilizer's time in the soil, thus increasing its sustained effectiveness and preventing nutrient deficiency in later stages of crop growth. Simultaneously, soil-burying fertilization promotes the adsorption of fertilizer by soil ions, thereby improving fertilizer utilization. Furthermore, burying fertilizer in the soil places it within the soil surrounding the crop roots, which is beneficial for root absorption. Since the root system of most crops is primarily distributed within the 8-15 cm layer of soil, burying fertilizer in the soil enhances the fertility around the roots. Combined with the relatively moist deeper soil layer, this further promotes nutrient absorption. Additionally, burying fertilizer in the soil encourages deeper root growth; the fertilizer below the roots induces root growth towards the fertilizer, promotes the development of more fibrous roots, and stabilizes the root system.

[0031] In some embodiments, the base 500 is positioned opposite the digging mechanism 600, which can limit the position of the soil excavated by the digging mechanism 600. This ensures that when the digging mechanism 600 retracts, the excavated soil can cover the dug pit, preventing the applied fertilizer from evaporating. Furthermore, after fertilization, the base 500 can be used to smooth the soil covering the pit.

[0032] Furthermore, please also refer to Figure 2 and Figure 6The digging mechanism 600 includes a pedal 610, a lever transmission assembly 620, and a shovel head 630. The pedal 610, lever transmission assembly 620, and shovel head 630 are connected sequentially from top to bottom, and the lever transmission assembly 620 is connected to the outer wall of the storage pipe 400. The lever transmission assembly 620 includes a first lever 621, a second lever 622, and a limiting assembly 623. The pedal 610 is movably connected to the driving end of the first lever 621, and the driven end of the first lever 621 is movably connected to a lever seat 420 disposed on the outer wall of the storage pipe 400. The driving end of the second lever 622 is connected to the first lever 621. The lower middle part of 1 is movably connected, and the driven end of the second lever 622 is movably connected to the limiting component 623; one end of the limiting component 623 is fixedly connected to the outer wall of the storage pipe 400, and a limiting part 6231 is provided on the side away from the storage pipe 400. The driven end of the second lever 622 is movably connected to the limiting part 6231 so that the driven end of the second lever 622 slides in the limiting part 6231; the shovel head 630 is fixedly connected to the side wall of the second lever 622 through the connecting rod 631 so that when the second lever 622 slides along the limiting part 6231, it drives the shovel head 630 to move, thereby realizing digging a hole.

[0033] Specifically, when digging a hole, pressing the pedal 610 applies a downward force to the active end of the first lever 621. As the active end of the first lever 621 moves downward, its driven end rotates with the lever seat 420, causing the first lever 621 to rotate downward with the lever seat 420 as the fulcrum. During the downward rotation of the first lever 621, the second lever 622 is also subjected to a downward force, pushing the driven end of the second lever 622 to slide along the limiting part 6231. At the same time, the second lever 622 drives the shovel head 630 to move towards the base 500. Since the limiting part 6231 is arc-shaped, that is, the movement trajectory of the driven end of the second lever 622 is arc-shaped, the shovel head 630 moves towards the base 500 while moving downward. The shovel head 630 gradually contacts the ground and digs a hole, thus using the lever principle to quickly and effortlessly achieve the digging action. The digging mechanism adopts a lever structure, which is simple in structure and low in cost, does not require additional control devices or power supplies, and is easy for operators to use.

[0034] In some embodiments, the shovel head 630 is designed with an inwardly concave arc surface, and the arc length gradually decreases from top to bottom until it forms a pointed tip. Initially, the arc surface of the shovel head forms an acute angle with the ground; as digging progresses, the angle between the arc surface and the ground gradually increases. When digging begins, the pointed tip at the bottom of the shovel head 630 can better break through the soil and extend downwards, facilitating digging and allowing fertilizer to be applied around the crop roots. During digging, the excavated soil adheres to the arc surface of the shovel head as it moves. After digging and fertilizing, releasing the pedal causes the shovel head 630 to return to its original position. As the shovel head 630 retreats, the soil adhering to its arc surface covers the previously dug pit, burying the fertilizer underground and preventing its volatilization.

[0035] Further, please see Figure 2 and Figure 5 The digging mechanism 600 also includes a return spring 640; one end of the return spring 640 is fixedly connected to the outer wall of the storage tube 400, and the other end is fixedly connected to the upper part of the first lever 621. When the pedal is pressed to dig a hole, the return spring 640 is stretched, and the stretched return spring will generate a rebound force; when the pedal is released, the return spring 640 will contract due to the rebound force, thereby pulling the first lever 621 to rotate upward, which in turn drives the second lever 622 to move upward, and drives the shovel head 630 back to its original position, realizing the automatic reset of the digging mechanism.

[0036] Furthermore, please also refer to Figure 3 , Figure 4 and Figure 6 A piston switch 410 is installed inside the storage tube 400 and fits against the inner wall of the storage tube to control the amount of material discharged from the storage tube 400. The piston switch 410 includes a storage part 411, a connecting part 412, and a spring 413. The upper part of the storage part 411 is higher than the upper end of the discharge port on the side wall of the storage tube 400. The connecting part 412 is located on the lower side of the storage part 411. One end of the spring 413 is fixedly located at the bottom of the storage part 411, and the other end is fixedly connected to the bottom of the storage tube 400. A rectangular opening is opened on the side of the storage tube 400 facing the digging mechanism 600. The connecting part 412 of the piston switch passes through the rectangular opening and rests on the upper part of the first lever 621.

[0037] After the fertilizer is loaded into the storage box, it falls sequentially from the conveying pipe and the support mechanism into the storage pipe and onto the storage part of the piston switch. Although the weight of the fertilizer presses down on the storage part 411 as it enters the storage pipe 400, the weight of the fertilizer is insufficient to press down the first lever 621 of the digging mechanism 600 because the connecting part 412 of the piston switch 400 rests on the upper part of the first lever 621. Since the first lever 621 is equipped with a return spring 640, the digging mechanism 600 remains in its initial state after the fertilizer enters the storage pipe 400. When the pedal 610 is pressed, the first lever 621 rotates downwards, creating a distance between the first lever 621 and the connecting part 412 of the piston switch 400. The piston switch, under the weight of the fertilizer, moves downwards, ensuring that the connecting part 412 remains resting on the first lever 621. As pedal 610 is continuously depressed, the shovel head 630 begins digging a hole, while the piston switch 410 continues to descend. When the upper part of the storage section 411 of the piston switch is lower than the upper end of the discharge port on the side wall of the storage pipe 400, fertilizer flows from the discharge port to the discharge mechanism 700, and then falls from the discharge mechanism 700 into the hole dug by the shovel head, thus achieving fertilization. When digging and fertilization are finished, pedal 610 is released, and the reset spring 640 resets the digging mechanism 600. The first lever 621 rotates upward, simultaneously causing the connecting part 412 to rise and reset. Furthermore, when the piston switch moves downward, it compresses the spring 413, causing the spring 413 to generate a rebound force. When digging and fertilization are finished, the first lever rotates upward, and the spring 413 begins to rebound, resetting the piston switch 410.

[0038] In some implementations, such as Figure 4 As shown, the storage section 411 is roughly shaped like a cross-sectioned cylinder. Specifically, the cylinder is obliquely cut from the side away from the discharge mechanism to the side closer to the discharge mechanism, and then becomes transversely cut as it approaches the discharge mechanism, thus forming the storage section. Therefore, the upper part of the storage section 411, viewed from the side, is first oblique and then flat. This design of the storage section 411 allows fertilizer accumulated on it to slide down towards the discharge mechanism 700 under the guidance of the oblique surface during fertilization, thereby accelerating the fertilizer conveying speed. Simultaneously, the flat surface design allows fertilizer to flow more effectively from the discharge port of the storage pipe 400 to the discharge port of the discharge mechanism 700, preventing fertilizer from accumulating on the inner wall of the discharge port of the storage pipe 400.

[0039] Furthermore, please also refer to Figure 2 , Figure 7 and Figure 8The discharge mechanism 700 includes a discharge pipe 710 and a guide pipe 720. The discharge pipe 710 is sleeved on the storage pipe 400, and the discharge port on the side wall of the storage pipe 400 corresponds to the discharge port of the discharge pipe 710. The guide pipe 720 is connected to the discharge port of the discharge pipe 710, and the end of the guide pipe 720 is inclined towards the storage pipe 400 and has a feeding port located between the base 500 and the digging mechanism 600. More specifically, as shown... Figure 7 and Figure 8 As shown, the feeding port is located between the base 500 and the shovel head 630 to ensure that fertilizer can be delivered to the pit dug by the shovel head 630. When the pedal 610 of the digging mechanism 600 is pressed, the first lever 621 moves downward and the second lever 622 moves along the limiting part 6231, which in turn moves the shovel head 630 along the limiting part 6231 to begin digging. During the downward movement of the first lever 621, a distance is created between the connecting part 412 of the piston switch 410 resting on the first lever 621 and the first lever 621. Since the fertilizer is piled on the piston switch 410 of the storage pipe 400, the weight of the fertilizer presses down on the storage part 411 and the connecting part 412 of the piston switch 410, causing them to move downward as well. As the storage section 411 continues to move downwards, the height of its upper surface gradually decreases below the upper end of the discharge port of the storage pipe 400. Fertilizer then flows from the discharge port of the storage pipe 400 to the discharge port of the discharge mechanism 700, enters the discharge pipe 710, flows to the guide pipe 720, and is discharged from the application port of the guide pipe 720. Since the application port of the guide pipe 720 is located between the base 500 and the digging mechanism 600, it ensures that the fertilizer is delivered to the hole dug by the digging mechanism 600, thereby delivering the fertilizer to the soil around the crop roots, which is beneficial for the absorption by the crop roots.

[0040] Further, please see Figure 2 and Figure 3 The discharge mechanism 700 also includes an adjusting plate 730, which is located between the discharge port on the side wall of the storage pipe 400 and the discharge port of the discharge pipe 710. The upper end of the adjusting plate 730 has a slotted hole, through which a bolt 740 passes to fix the adjusting plate 730 to the outer wall of the storage pipe 400. Because the upper end of the adjusting plate 730 has a slotted hole, the position of the adjusting plate 730 can be adjusted by adjusting the position of the bolt 740 within the slotted hole. Since the adjusting plate 730 is located between the two discharge ports, adjusting its position adjusts the opening state of the discharge ports, thereby regulating the flow rate of fertilizer from the storage pipe to the discharge pipe. The position of the adjusting plate 730 can be arbitrarily adjusted according to the required amount of fertilizer to be applied.

[0041] Further, please see Figure 1A handheld part 310 is provided on the upper part of the support mechanism 300, away from the storage box 100. Specifically, the support mechanism 300 includes a handheld part 310, a straight cylindrical part 320, and a connecting part 330. The upper end of the straight cylindrical part 320 is sealed and hollow inside, and the lower end is connected to the storage pipe 400. The connecting part 330 is located on the upper side of the straight cylindrical part 320, and one end of the connecting part 330 is connected to the conveying pipe 200, and the other end is connected to the side wall of the straight cylindrical part 320. The handheld part 310 is located on one side of the upper end of the straight cylindrical part and is opposite to the connecting part 330. When the base 500 is placed on the ground, the operator holds the handheld part 310 and then steps on the digging mechanism 600 to dig a hole and apply fertilizer. By providing the handheld part 310, it is convenient for the operator to apply force when stepping on the digging mechanism, and it also ensures that the entire device remains stable during the digging process, allowing the digging action to be carried out stably.

[0042] Further, please see Figure 1 A vibration mechanism 110 is installed on one side of the storage bin 100. The vibration mechanism 110 is mounted on the outside of the storage bin, and a battery is installed inside the mechanism, while an operating switch is located on the outside. When fertilizing, the vibration mechanism 110 is activated to cause the storage bin 100 to vibrate, preventing fertilizer from clumping and clogging the discharge port, and facilitating discharge. A lid is also installed on top of the storage bin to reduce fertilizer volatilization.

[0043] Further, please see Figure 1 Each end of the storage box is equipped with a carrying strap 120. Specifically, the carrying strap 120 is positioned opposite the vibration mechanism 110. The carrying strap 120 allows the storage box 100 to be carried on the back of the operator. This is convenient for operators to carry the fertilization device, especially in mountainous areas or areas with small planting areas. Operators can also carry the storage box 100 on their backs while fertilizing, thus improving the convenience of fertilization operations. In some embodiments, the delivery pipe 200 is a flexible hose. The angle of the delivery pipe 200 can be adjusted during fertilization. Different angles of the delivery pipe 200 result in different orientations of the support mechanism 300, storage pipe 400, base 500, digging mechanism 600, and discharge mechanism 700. Therefore, the angle of the delivery pipe 200 can be adjusted according to the fertilization location to ensure that the fertilizer is applied to the correct position.

[0044] Furthermore, the storage bin is equipped with a spiral mechanism. The spiral mechanism includes a spiral rod and a rotating motor. The rotating motor is fixedly connected to the inner walls of the storage bin on both sides near the top via a fixed rod. The spiral rod is fixedly installed at the output end of the rotating motor, and the bottom end of the spiral rod extends into the storage bin and is close to the discharge port. This allows the rotating motor to precisely control the amount of fertilizer discharged, avoiding excessive fertilization that could damage the corn roots. At the same time, it also stirs the fertilizer in the storage bin, preventing it from clumping and clogging the discharge port.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
