Description

Technical Field

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

[0002] Mechanical fertilization devices are agricultural machinery used in agricultural production to replace manual labor and achieve efficient and precise application of fertilizers. Their core function is to store, quantitatively transport, and apply fertilizers such as chemical and organic fertilizers through the coordination of mechanical structure and power systems. In agricultural production, fertilization is a crucial step in ensuring crop growth and increasing yield. With the development of large-scale and mechanized agriculture, mechanical fertilization devices have been widely used because they can significantly improve fertilization efficiency and reduce the intensity of manual labor.

[0003] However, existing mechanical fertilization devices have significant shortcomings in fertilizer mixing. Traditional devices mostly employ a simple single-shaft mixing structure, relying solely on a single stirring rod or blade to agitate the fertilizer. Due to the diverse types of fertilizers, such as granular and powdered fertilizers, clumping may occur. This single structure makes it difficult to achieve comprehensive and thorough mixing of fertilizers, easily leading to localized accumulation and uneven mixing. Uneven fertilizer mixing results in uneven nutrient absorption by crops after fertilization. In some areas, crop growth is restricted due to insufficient nutrients, while in other areas, nutrient excess leads to waste and even soil pollution, seriously affecting crop growth and development and the effectiveness of fertilization.

[0004] Meanwhile, existing equipment has low mixing efficiency. When dealing with large amounts of fertilizer required for large-scale farmland, it often takes a long time to complete the mixing process, which is insufficient to meet the needs of efficient operations in agricultural production and restricts the overall progress of fertilization. Therefore, there is an urgent need for a mechanical fertilization device with efficient and thorough mixing capabilities to ensure uniform fertilizer mixing, improve fertilization efficiency, and help improve the quality and efficiency of agricultural production. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical fertilization device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a mechanical fertilization device, including a fertilizer truck body. A fertilizer box is fixedly installed on the top of the fertilizer truck body. A box cover is provided on the top of the fertilizer box. A servo motor is provided on the top of the box cover. A connecting rod is connected to the drive end of the servo motor. A first stirring rod, a second stirring rod, a second stirring blade, and a stirring component are fixedly installed on the outer wall of the connecting rod. A first stirring blade is fixedly installed between the first stirring rod and the second stirring rod. Another first stirring blade is fixedly installed between the second stirring rod and the stirring component.

[0007] Furthermore, the inner frame of the fertilizer box is wider at the top and narrower at the bottom.

[0008] Furthermore, the stirring component is composed of multiple third stirring rods, which are arranged in a radial pattern with the connecting rod near the bottom as the central meeting point, extending outward from the center.

[0009] Furthermore, the first stirring blade is S-shaped, and the upper and lower surfaces of the second stirring blade are wavy.

[0010] Furthermore, the length of the first stirring rod is greater than the length of the second stirring rod, and the length of the second stirring rod is greater than the length of the third stirring rod.

[0011] Furthermore, an installation block is fixedly installed on the outer wall of the fertilizer box, and a fixing bolt is threaded to the bottom of the installation block.

[0012] Furthermore, a pusher is fixedly installed on the body of the fertilizer applicator, a feed hopper is fixedly installed on the top of the box cover, and a cover is provided on the top of the feed hopper.

[0013] Furthermore, a discharge pipe is installed at the bottom of the fertilizer box, and an electric valve is installed inside the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the servo motor is started, and its drive end drives the connecting rod to rotate. The first and second stirring rods initially stir and disperse the fertilizer, while the first and second stirring blades further mix it. The stirring components assist from different angles to ensure that the fertilizer is fully and evenly mixed. Then, the electric valve of the discharge pipe at the bottom of the fertilizer box is opened, and the mixed fertilizer is discharged, completing the fertilization process.

[0018] 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.

[0019] Please see Figures 1-4 This utility model provides a technical solution: See Figures 1-4 As shown, a mechanical fertilization device includes a fertilizer truck body 1, a fertilizer box 2 fixedly installed on the top of the fertilizer truck body 1, a box cover 11 provided on the top of the fertilizer box 2, a servo motor 4 provided on the top of the box cover 11, a connecting rod 5 connected to the drive end of the servo motor 4, a first stirring rod 6, a second stirring rod 7, a second stirring blade 9, and a stirring component 10 fixedly installed on the outer wall of the connecting rod 5, a first stirring blade 8 fixedly installed between the first stirring rod 6 and the second stirring rod 7, and another first stirring blade 8 fixedly installed between the second stirring rod 7 and the stirring component 10.

[0020] When the mechanical fertilization device is working, fertilizer is fed into the fertilizer box 2 through the feed hopper 12. Then, the servo motor 4 is started, and its drive end rotates the connecting rod 5. During the rotation of the connecting rod 5, the first stirring rod 6, the second stirring rod 7, the second stirring blade 9, the stirring element 10, and the first stirring blade 8, all fixed to its outer wall, rotate together. The first stirring rod 6 and the second stirring rod 7 initially agitate and disperse the fertilizer, while the first stirring blade 8 and the second stirring blade 9 further mix the fertilizer. The stirring element 10 assists in mixing from different angles, ensuring that the fertilizer in the fertilizer box 2 is thoroughly and evenly mixed under the combined action of these components. Afterward, the electric valve on the discharge pipe at the bottom of the fertilizer box 2 is opened, and the evenly mixed fertilizer is discharged from the discharge pipe, thus completing the fertilization operation.

[0021] The servo motor 4 drives the connecting rod 5 and various stirring components to rotate, ensuring that the fertilizer in the fertilizer tank 2 is thoroughly and comprehensively mixed. This prevents fertilizer from accumulating in certain areas or being unevenly mixed, ensuring that the discharged fertilizer has a uniform composition, allowing crops to absorb nutrients evenly and promoting their growth and development. Simultaneously, the coordinated operation of multiple stirring components results in high mixing efficiency, enabling fertilizer mixing to be completed in a short time, improving the operational efficiency of the fertilization device and meeting the needs of large-scale farmland fertilization.

[0022] See Figure 2 The inner frame of fertilizer box 2 is wider at the top and narrower at the bottom.

[0023] The inner frame of fertilizer box 2 is wider at the top and narrower at the bottom. When adding fertilizer to fertilizer box 2, the wider top makes it easier to pour the fertilizer in and reduces the possibility of fertilizer spilling outside the fertilizer box 2. The narrower bottom helps the fertilizer to gather towards the discharge pipe under its own weight. When fertilizer needs to be discharged, the fertilizer can flow out more smoothly from the bottom discharge pipe, avoiding fertilizer accumulation at the bottom of fertilizer box 2. This ensures the continuity and uniformity of fertilizer discharge during the fertilization process. It also facilitates the stirring component to fully mix the fertilizer, improves the fertilizer mixing effect, and makes the fertilization operation more efficient and smooth.

[0024] See Figure 2-3 The stirring component 10 is composed of multiple third stirring rods, which are arranged in a radial pattern with the connecting rod 5 near the bottom as the central meeting point, extending outward from the center.

[0025] The mixing component 10 consists of multiple third mixing rods, which converge at the center near the bottom of the connecting rod 5 and are distributed in a radial pattern, extending outward from the center. During fertilizer mixing, they can agitate the fertilizer at the bottom of the fertilizer tank 2 from different directions, enhancing the horizontal and radial flow of the fertilizer. This ensures that the fertilizer is fully dispersed and mixed even in the bottom accumulation area, preventing fertilizer from settling or clumping at the bottom of the fertilizer tank 2. It also helps to push the fertilizer evenly to the discharge port, ensuring the continuity and uniformity of fertilizer discharge and improving the efficiency and effectiveness of fertilization operations.

[0026] See Figure 3 The first stirring blade 8 is S-shaped, and the upper and lower surfaces of the second stirring blade 9 are wavy.

[0027] The size of the radial stirring element 10 directly affects the flow and mixing effect of fertilizer in the fertilizer box 2. A larger size provides a wider coverage area, can drive more fertilizer flow, and improves the overall mixing uniformity, but may increase the motor load; a smaller size limits the stirring range and may lead to uneven local mixing, but has lower operating resistance and lower energy consumption. The first stirring blade 8 is S-shaped, which can create multi-directional material pushing and shearing during rotation, promoting fertilizer exchange between different layers and enhancing the mixing effect; the upper and lower surfaces of the second stirring blade 9 are wavy, which can increase the contact area with fertilizer, improve the stirring shearing force, and at the same time create an up-and-down rolling flow effect, reducing fertilizer accumulation in local areas, and making different types and particle sizes of fertilizers more evenly mixed together, which is conducive to subsequent uniform fertilization and improves the crop's nutrient absorption efficiency.

[0028] See Figure 3 The length of the first stirring rod 6 is greater than the length of the second stirring rod 7, and the length of the second stirring rod 7 is greater than the length of the third stirring rod.

[0029] The length of the first stirring rod 6 is greater than the length of the second stirring rod 7, and the length of the second stirring rod 7 is greater than the length of the third stirring rod. This allows the stirring rods of different lengths to be distributed at different radii within the fertilizer box 2. When the connecting rod 5 rotates, the first stirring rod 6 can stir the fertilizer in the upper and outer middle areas of the fertilizer box 2, the second stirring rod 7 can stir the fertilizer in the inner middle area, and the third stirring rod can stir the fertilizer in the bottom center and surrounding areas. This achieves all-round stirring of fertilizer at different heights and radii within the fertilizer box 2, preventing local fertilizer from being unable to be effectively mixed. It also reduces fertilizer retention near the box walls, making the fertilizer mixture more uniform and facilitating the even distribution of nutrients during subsequent fertilization, thus improving the fertilization effect.

[0030] See Figure 4A mounting block 14 is fixedly installed on the outer wall of the fertilizer box 2. A fixing bolt 13 is threadedly connected to the bottom of the mounting block 14. A throttle handle is fixedly installed on the fixing bolt 13. The fertilizer box 2 and the box cover 11 are fixedly connected by the fixing bolt 13.

[0031] An installation block 14 is fixedly installed on the outer wall of the fertilizer box 2. A fixing bolt 13 is threadedly connected to the bottom of the installation block 14. A handle is fixedly installed on the fixing bolt 13. The fertilizer box 2 and the box cover 11 are fixedly connected by the fixing bolt 13. When it is necessary to open the box cover 11 to add fertilizer or to repair the internal parts of the fertilizer box 2, the operator only needs to turn the handle to loosen the fixing bolt 13. No additional tools are required, which is convenient and saves time. During the fertilization operation, the fixing bolt 13 can firmly fix the box cover 11 to the fertilizer box 2, preventing the box cover 11 from loosening or shifting due to the movement of the fertilizer vehicle body 1 or the vibration caused by the rotation of the stirring parts. This prevents fertilizer from leaking out of the gaps or external dust and impurities from entering the fertilizer box 2 and contaminating the fertilizer, ensuring the smooth progress of the fertilization operation.

[0032] See Figure 1 The fertilizer truck body 1 is fixedly equipped with a pusher 3, and the top of the box cover 11 is fixedly equipped with a feed hopper 12, and the top of the feed hopper 12 is equipped with a cover.

[0033] A push handle 3 is fixedly installed on the top of the fertilizer applicator body 1. The operator can easily move the fertilizer applicator body 1 in the field by holding the push handle 3, which facilitates flexible adjustment of the fertilization position according to the crop planting area, reduces the physical consumption of moving the fertilizer applicator, and improves the flexibility of operation. A feed hopper 12 is fixedly installed on the top of the box cover 11. When adding fertilizer into the fertilizer box 2, the feed hopper 12 can guide the fertilizer to fall accurately into the box, reducing the possibility of fertilizer spilling outside the box. At the same time, the feeding can be completed without fully opening the box cover 11, reducing the probability of external impurities entering the fertilizer box 2. The top of the feed hopper 12 is equipped with a cover. When no fertilizer is added, the cover can close the feed hopper 12 to prevent dust and debris from entering the fertilizer box 2 through the feed hopper 12 during the fertilization operation and contaminating the fertilizer. It can also reduce the amount of dust generated by the fertilizer being stirred from overflowing from the feed hopper 12, ensuring the purity of the fertilizer and the cleanliness of the working environment, and helping to carry out fertilization operations efficiently.

[0034] See Figure 1-2 The bottom of fertilizer box 2 is equipped with a discharge pipe, and an electric valve is installed inside the discharge pipe.

[0035] The bottom of fertilizer tank 2 is equipped with a discharge pipe, inside which is an electric valve. When fertilizer needs to be discharged for fertilization, the opening of the electric valve allows the evenly mixed fertilizer in fertilizer tank 2 to flow smoothly out along the discharge pipe without the need for manual opening or closing of the discharge structure, making operation more convenient. At the same time, the opening degree of the electric valve can be adjusted to control the fertilizer discharge speed and flow rate, adapting to different crop planting densities and fertilizer application requirements, avoiding excessive or insufficient fertilizer discharge that would affect the fertilization effect. When fertilization is paused or the fertilizer in fertilizer tank 2 is insufficient, the electric valve can be quickly closed to prevent fertilizer from continuing to leak out and causing waste. It also prevents external soil and impurities from entering fertilizer tank 2 through the discharge pipe and contaminating the remaining fertilizer, ensuring the controllability of the fertilization process and the purity of the fertilizer, and helping to complete fertilization operations efficiently.

[0036] The electric valve is powered by an external power source.
