Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, and in particular to a precision fertilization device with adjustable fertilizer application rate. Background Technology

[0002] Fertilizers used in agricultural arable land are usually solid fertilizers, which can be further divided into granular fertilizers and powder fertilizers. Granular fertilizers usually have better physical properties, such as fluidity and stability, making them suitable for mechanical fertilization and long-lasting fertilization. Powder fertilizers, on the other hand, have a larger surface area and release nutrients faster, making them suitable for rapid nutrient replenishment and small-area manual application.

[0003] Determining the amount of fertilizer applied during mechanical fertilization is crucial for ensuring normal crop growth. Currently, fertilizer dispensers are commonly used to quantify fertilizer application. However, traditional fertilizer dispensers have a fixed capacity, meaning the amount of fertilizer applied per cycle is fixed. The only way to increase or decrease the amount of fertilizer is by changing the frequency of operation, making the adjustment method rather limited. When it is necessary to increase the amount of fertilizer, adjusting the fertilizer application by changing the speed of the dispenser is prone to errors. This is because fertilizer needs to slide down from the hopper and fill the dispenser by gravity, a process that takes time. The larger the capacity of the dispenser, the longer it takes to fill. If the speed is too fast, the fertilizer particles may be discharged before the dispenser is fully filled, resulting in a deviation in the amount of fertilizer applied and affecting the fertilization effect.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] See Figure 1-9 A precision fertilization device with adjustable fertilizer application rate, comprising:

[0042] The frame 1 is made of welded steel. A connector 11 is provided at the front end of the frame 1 for easy connection to mobile equipment such as tractors. A bracket 12 is fixedly connected to the frame 1. A hopper 2 for holding fertilizer granules is fixedly installed on the top of the bracket 12. The bottom of the hopper 2 has a funnel-shaped structure to facilitate the sliding of fertilizer granules. The bottom of the hopper 2 has multiple fertilizer discharge ports evenly opened. The number of fertilizer discharge ports can be increased or decreased according to actual needs. In this embodiment, four fertilizer discharge ports are provided. A rotating shaft 4 is also rotatably installed on the bracket 12, and the rotating shaft 4 can slide left and right on the bracket 12 along its axial direction.

[0043] Fertilizer applicator 3; Fertilizer applicator 3 includes a fertilizer discharge box 31 and a fertilizer discharge wheel 32. The fertilizer discharge box 31 is fixedly connected to the fertilizer discharge port of the hopper 2. A feed inlet 311 corresponding to the fertilizer discharge port is opened on the top of the fertilizer discharge box 31. The fertilizer discharge wheel 32 is rotatably connected inside the fertilizer discharge box 31. The fertilizer discharge wheel 32 is fixedly connected to a rotating shaft 4, and the rotating shaft 4 drives the fertilizer discharge wheel 32 to rotate. Further details can be found in the following sections. Figure 5 A partition 33 is provided in the middle of the fertilizer dispensing wheel 32, which divides the fertilizer dispensing wheel 32 into two equal parts, left and right. The left side of the wheel has a first groove 321 evenly distributed, and the other side has a second groove 322 evenly distributed. The first groove 321 and the second groove 322 have different capacities, which can be adjusted according to needs. The width of the first groove 321 and the second groove 322 is the same as the width of the fertilizer box 31, thereby ensuring the sealing between the fertilizer box 31 and the fertilizer dispensing wheel 32 and preventing fertilizer particles from leaking out from the gaps. An adjustable limiting claw 44 is also installed on the bracket 12. The limiting claw 44 can drive the rotating shaft 4 to slide along its axial direction, thereby changing the position of the fertilizer dispensing wheel 32 in the fertilizer box 31, so that the first groove 321 or the second groove 322 is aligned with the feed inlet 311, thereby adjusting the capacity of the fertilizer dispensing mechanism 3 and thus adjusting the amount of fertilizer applied.

[0044] See Figure 2-4A limiting frame 48 is fixedly connected to the bracket 12. A first gear 45 is rotatably mounted on the limiting frame 48. The first gear 45 is provided with a limiting protrusion 451. A groove 41 is opened at the end of the rotating shaft 4. The limiting protrusion 451 is slidably connected in the groove 41, so that the first gear 45 can drive the rotating shaft 4 to rotate while also sliding along the axial direction of the rotating shaft 4. A motor 47 is also fixedly mounted on the bracket 12. A second gear 46 that meshes with the first gear 45 is fixedly connected to the output shaft of the motor 47. In use, the motor 47 can drive the rotating shaft 4 to rotate, thereby driving the fertilizer discharge wheel 32 to rotate in the fertilizer discharge box 31. When the first groove 321 or the second groove 322 on the fertilizer discharge wheel 32 is connected to the feed port 311, the fertilizer particles fill the groove under the action of gravity, realizing quantitative distribution. As the fertilizer discharge wheel 32 rotates, when the groove is connected to the discharge port 312 at the bottom of the fertilizer discharge box 31, the fertilizer particles are discharged under the action of gravity. The amount of fertilizer discharged by the fertilizer discharge wheel 32 in one rotation is equal to the sum of the capacities of the first groove 321 or the second groove 322.

[0045] When fertilizing, the smaller capacity second groove 322 is used first. When it is necessary to increase the amount of fertilizer, the amount of fertilizer is increased by increasing the speed of the fertilizer discharge wheel 32. When increasing the speed affects the filling of the fertilizer granules into the second groove 322, the larger capacity first groove 321 is switched to fertilize.

[0046] In some embodiments, the switching method between the first groove 321 and the second groove 322 is as follows: A telescopic rod 43 is fixedly connected laterally to the bracket 12. The telescopic rod 43 is an electric telescopic rod. During installation, it is necessary to ensure that the axial direction of the telescopic rod 43 is parallel to the axial direction of the rotating shaft 4. An adjusting plate 42 is set on the rotating shaft 4. A limiting claw 44 corresponding to the adjusting plate 42 is fixedly connected to the end of the telescopic rod 43. The limiting claw 44 has a U-shaped structure. The groove on the limiting claw 44 locks the left and right sides of the adjusting plate 42, so that the adjusting plate 42 can rotate normally, but cannot slide along the axial direction of the rotating shaft 4. By adjusting the extension of the telescopic rod 43, the limiting claw 44 can drive the adjusting plate 42 to move left and right along the axial direction of the rotating shaft 4, thereby switching between the first groove 321 and the second groove 322. Compared with traditional fertilizer applicators that can only adjust the fertilizer application rate by relying on the rotation speed, this method increases the means of fertilizer application rate adjustment by directly adjusting the capacity of the fertilizer applicator 3, thus alleviating the problem of fertilizer application rate deviation caused by the rotation speed.

[0047] See Figure 8 , 9A crossbeam 13 is fixedly connected to the frame 1. A soil-breaking mechanism 6 corresponding to the fertilization mechanism 3 is installed on the crossbeam 13. The soil-breaking mechanism 6 includes a slider 61, fixing bolts 62, shock absorbers 63, connecting blocks 64, and soil-breaking discs 65. The slider 61 is slidably connected to the crossbeam 13, and the corresponding fixing bolts 62 of the crossbeam 13 are installed on the slider 61 by bolts. The position of the slider 61 can be fixed by tightening the fixing bolts 62. A connecting block 64 is installed at the bottom of the slider 61 by shock absorbers 63. Soil-breaking discs 65 are symmetrically installed on the connecting block 64. The two soil-breaking discs 65 are arranged in a conical shape, with the narrower end located in front of the direction of travel to break the soil. The wider end is located in the rear of the direction of travel to facilitate fertilization. A clamp 66 is also provided on the slider 61. One end of the fertilizer discharge pipe 5 is connected to the discharge port 313 of the fertilizer discharge box 31, and the other end is fixed to the clamp 66. During use, as the frame 1 moves, the surface soil is separated to both sides by the breaking plate 65. The fertilizer particles enter the fertilizer discharge pipe 5 from the discharge port 313 and are discharged from the rear side of the breaking plate 65, falling into the deep soil. Finally, the land is flattened again by the compaction wheel 7, so that the fertilizer particles are buried deep in the soil.

[0048] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0049] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
