Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of fertilization technology, and more specifically, to a crop fertilization device for agricultural planting. Background Technology

[0002] Currently, agricultural fertilization in my country still relies on manual spreading and small-scale mechanical spraying, making it difficult to accurately control the amount of fertilizer applied. This often results in fertilizer application far exceeding the actual needs of crops, leading to fertilizer waste and pollution of water and soil. Furthermore, these outdated methods cause uneven distribution of fertilizer in the field, affecting crop yields. Moreover, they are highly dependent on manual labor, inefficient, and fail to improve economic benefits.

[0003] With population growth and social development, the demand for food is constantly increasing. Traditional farming methods are inefficient, costly, and severely damage the soil, making it difficult to meet the needs of modern agriculture for high efficiency and precision. The research and application of mechanized planting equipment has become an important direction for current agricultural production. Both domestic and foreign countries are actively researching and applying various agricultural mechanized fertilization devices, such as no-till grain planters with furrowing fertilization devices, in order to improve fertilization efficiency and quality and reduce labor intensity. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a crop fertilization device for agricultural planting, which solves the problems of existing technologies that still rely on manual spreading and small mechanical spraying, resulting in difficulty in accurately controlling the amount of fertilizer applied. This often leads to situations where the amount of fertilizer applied far exceeds the actual needs of crops, causing not only fertilizer waste but also pollution of water and soil due to excess fertilizer. In addition, the old-fashioned operation methods cause uneven distribution of fertilizer in the field, affecting farmland yield. Furthermore, they are highly dependent on manual labor, inefficient, and difficult to improve economic benefits.

[0005] According to one aspect, at least one embodiment of this disclosure provides a crop fertilization device for agricultural planting, comprising: A fertilizer bucket, the upper end of which is equipped with a fertilizer cover; A fertilizer application drive assembly is disposed inside the fertilizer application tank; A linkage limiting component is disposed inside the fertilizer tank; The driving fertilizer application component includes a centrifugal disc disposed inside the fertilizer application tank. The centrifugal disc has a collection trough inside and a separation plate inside. The upper end face of the centrifugal disc has a centrifugal agitator bar, and the lower end face of the centrifugal disc has a drive shaft.

[0006] As a further technical solution, the outer wall of the fertilizer tank is provided with a fertilizer inlet, the fertilizer inlet is positioned corresponding to the centrifugal disc, and the side wall of the fertilizer inlet is provided with an expansion plate, the expansion plate being located at opposite ends of the fertilizer inlet.

[0007] As a further technical solution, the linkage limiting component includes a support frame, which is disposed on the inner side wall of the fertilizer tank. A limiting ring is disposed inside the support frame, and a limiting connecting ring is disposed inside the limiting ring. The limiting connecting ring is fitted onto the drive shaft.

[0008] As a further technical solution, the inner sidewall of the limiting ring is provided with a connecting shaft, a connecting wheel is fitted on the connecting shaft, a limiting piece is attached to the sidewall of the connecting wheel, and the limiting piece is disposed on the drive shaft.

[0009] As a further technical solution, the upper end face of the fertilizer bucket has an insertion interface, and the fertilizer cover is embedded inside the fertilizer bucket.

[0010] As a further technical solution, the lower end of the fertilizer hood is provided with a drop-out port, which is located directly above the collection trough.

[0011] As a further technical solution, an output motor is provided at the lower end of the drive shaft, and the output motor is located at the inner bottom of the fertilizer tank.

[0012] As a further technical solution, the number of the connecting wheels is several, and the several connecting wheels are arranged at the upper and lower ends of the limiting plate.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: This invention utilizes centrifugal force to achieve rapid fertilizer application. Compared to traditional manual fertilization, it can cover a larger area in a short time, significantly improving fertilization efficiency. It is particularly suitable for large-scale agricultural planting scenarios. The centrifugal disc's separating plates can break up clumps of fertilizer, and together with the centrifugal agitator strips, the fertilizer is evenly ejected under centrifugal force. The expansion plates at the fertilizer inlet further expand the application range and optimize the distribution, reducing the problem of localized fertilizer accumulation or sparse distribution, ensuring uniform fertilization of crops, which is beneficial to crop growth. The device is driven by a motor to achieve automated fertilization, reducing the intensity of manual operation and labor costs. The fertilizer is precisely guided into the working area by the fertilizer hood. The operation process is simple, making it easy for farmers to quickly master the usage method.

[0016] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0017] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] like Figures 1-3 As shown, it illustrates an agricultural crop fertilization device of this disclosure, comprising: Fertilizer bucket 1, with a fertilizer cover 2 installed at the top of fertilizer bucket 1; The fertilizer application component 3 is driven and installed inside the fertilizer tank 1. Linkage limit component 4 is installed inside fertilizer tank 1; The driving fertilizer application component 3 includes a centrifugal disc 3-1, which is located inside the fertilizer application tank 1. A collection trough 3-2 is provided inside the centrifugal disc 3-1, and a separation plate 3-3 is provided inside the collection trough 3-2. A centrifugal agitator bar 3-4 is provided on the upper end face of the centrifugal disc 3-1, and a drive shaft 3-5 is provided on the lower end face of the centrifugal disc 3-1.

[0023] The linkage limiting component 4 includes a support frame 4-1, which is set on the inner side wall of the fertilizer tank 1. A limiting ring 4-2 is set inside the support frame 4-1, and a limiting connecting ring 4-3 is set inside the limiting ring 4-2. The limiting connecting ring 4-3 is fitted on the drive shaft 3-5.

[0024] In some examples, the driving fertilizer assembly 3 is the core part of realizing the fertilization function. It includes a centrifugal disc 3-1 installed inside the fertilizer tank 1. The centrifugal disc 3-1 has a collection tank 3-2 inside to receive fertilizer falling from the drop port 6. A separating plate 3-3 is installed in the collection tank 3-2 to disperse the fertilizer in the collection tank 3-2 and prevent fertilizer from accumulating. The upper end of the centrifugal disc 3-1 is provided with a centrifugal agitator 3-4. When the centrifugal disc 3-1 rotates, the centrifugal agitator 3-4 can help the fertilizer to be thrown out better.

[0025] The linkage limiting assembly 4 is used to limit and assist the rotation of the drive shaft 3-5. It includes a support frame 4-1 fixed to the inner wall of the fertilizer tank 1. A limiting ring 4-2 is installed inside the support frame 4-1. A limiting connecting ring 4-3 is provided inside the limiting ring 4-2. The limiting connecting ring 4-3 is fitted on the drive shaft 3-5 and plays a preliminary limiting role on the drive shaft 3-5.

[0026] like Figures 1-3 As shown in the figure, this embodiment proposes to provide a fertilizer inlet 3-6 on the outer side wall of the fertilizer tank 1. The fertilizer inlet 3-6 corresponds to the position of the centrifugal disc 3-1. An expansion plate 3-7 is provided on the side wall of the fertilizer inlet 3-6, and the expansion plate 3-7 is located at the opposite ends of the fertilizer inlet 3-6.

[0027] In some examples, the fertilizer tank 1 serves as the main body of the device, and its outer wall is provided with a fertilizer inlet 3-6. The fertilizer inlet 3-6 corresponds to the position of the centrifugal disc 3-1, which facilitates the discharge of fertilizer from the fertilizer tank 1. On the side wall of the fertilizer inlet 3-6, at its opposite ends, expansion plates 3-7 are installed. The expansion plates 3-7 can expand the fertilizer spreading range and improve fertilization efficiency.

[0028] For example, such as Figure 3 As shown, the inner sidewall of the limiting ring 4-2 is provided with a connecting shaft 4-4, and a connecting wheel 4-5 is fitted on the connecting shaft 4-4. The sidewall of the connecting wheel 4-5 is fitted with a limiting piece 4-6, and the limiting piece 4-6 is set on the drive shaft 3-5.

[0029] In some examples, when the drive shaft 3-5 rotates, the limiting plate 4-6 rotates accordingly, and the connecting wheel 4-5 rotates on the connecting shaft 4-4, further ensuring the stability of the rotation of the drive shaft 3-5, reducing the shaking of the drive shaft 3-5 during high-speed rotation, and ensuring the stable progress of fertilization operations. The connecting shaft 4-4 is installed on the inner side wall of the limiting ring 4-2, and the connecting wheel 4-5 is fitted on the connecting shaft 4-4. There are several connecting wheels 4-5, and these several connecting wheels 4-5 are placed at the upper and lower ends of the limiting plate 4-6. The side wall of the connecting wheel 4-5 is in close contact with the limiting plate 4-6 set on the drive shaft 3-5.

[0030] For example, such as Figure 2As shown, the fertilizer bucket 1 has an insertion interface 5 on its upper end face, the fertilizer cover 2 is embedded inside the fertilizer bucket 1, and the fertilizer cover 2 has a drop hole 6 at its lower end, which is located directly above the collection trough 3-2.

[0031] In some examples, the upper end of the fertilizer bucket 1 has an insertion interface 5, the fertilizer cover 2 is embedded inside the fertilizer bucket 1, and the lower end of the fertilizer cover 2 is provided with a drop outlet 6, which is located directly above the collection tank 3-2. In this way, the fertilizer put in from the fertilizer outlet 3-6 can fall accurately into the collection tank 3-2 of the centrifugal disc 3-1 through the drop outlet 6 of the fertilizer cover 2.

[0032] For example, such as Figure 2 As shown, an output motor 7 is installed at the lower end of the drive shaft 3-5, and the output motor 7 is located at the inner bottom of the fertilizer tank 1.

[0033] In some examples, the lower end face of the centrifugal disc 3-1 is connected to a drive shaft 3-5, and the lower end of the drive shaft 3-5 is equipped with an output motor 7. The output motor 7 is fixed to the inner bottom of the fertilizer tank 1. When the output motor 7 is working, it drives the centrifugal disc 3-1 to rotate at high speed through the drive shaft 3-5, and uses centrifugal force to throw the fertilizer in the collection tank 3-2 out of the fertilizer port 3-6 to complete the fertilization operation.

[0034] For example, such as Figure 3 As shown, there are several connecting wheels 4-5, and several connecting wheels 4-5 are placed at the upper and lower ends of the limiting plate 4-6.

[0035] When in use, the operator puts the fertilizer into the fertilizer inlet 3-6 at the top of the fertilizer tank 1. After the fertilizer is collected by the fertilizer cover 2, it falls precisely into the collection tank 3-2 of the centrifugal disc 3-1 through the drop outlet 6 at the bottom.

[0036] The design of the fertilizer hood 2 can prevent fertilizer from scattering into other areas inside the device during the application process, ensuring that the fertilizer is concentrated in the working area. After the output motor 7 is started, the motor drives the centrifugal disc 3-1 to rotate at high speed through the drive shaft 3-5. The fertilizer in the collection tank 3-2 moves outward under the action of centrifugal force. During the process, it is broken up by the separation plate 3-3 in the collection tank 3-2 to prevent clumping. When the fertilizer moves to the edge of the centrifugal disc 3-1, it is quickly thrown out of the centrifugal disc 3-1 with the assistance of the centrifugal agitator 3-4.

[0037] The fertilizer ejected is discharged through the fertilizer inlet 3-6 on the side wall of the fertilizer tank 1. The expansion plate 3-7 at the fertilizer inlet 3-6 further spreads the fertilizer to both sides, expanding the coverage area and ensuring that the fertilizer is evenly distributed in the crop planting area. During the high-speed rotation of the drive shaft 3-5, the linkage and limiting assembly 4 works synchronously: the limiting connecting ring 4-3 forms a radial constraint on the drive shaft 3-5 to prevent large deviations; the limiting plate 4-6 on the drive shaft 3-5 is tightly fitted with the linkage wheel 4-5, and the linkage wheel 4-5 generates rolling support as it rotates with the drive shaft 3-5, reducing axial sway.

[0038] This combined structure ensures that the drive shaft 3-5 and the centrifugal disc 3-1 always maintain a stable rotation state, avoiding uneven fertilizer spreading or damage to the device due to vibration.
