Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a fertilizer transmission mechanism, a fertilizer application device, and agricultural equipment. Background Technology

[0002] Fertilizer applicators are common equipment in agricultural operations, used to apply fertilizer to crops to meet the needs of plant growth.

[0003] There are many fertilization devices on the market. For example, patent application number 201820057600.5 discloses the following technology: a seeder drive wheel, consisting of a wheel, wheel frame, wheel frame fixing plate, spring, frame, fertilizer box, hexagonal shaft, chain, and gear. There is one drive wheel on each side of the seeder, and the overall structure is symmetrical. The wheel frame has a V-shaped structure with the corners facing outwards. The wheel surface has vertical grooves, and the lower end of the wheel frame has a one-way transmission bearing structure, through which the wheel frame is connected to the wheel. The middle part of the wheel frame is connected to the wheel frame fixing plate, and the upper end of the wheel frame is connected to the spring. The wheel frame fixing plate has an inverted U-shaped structure with an elongated hole in the middle of the upper part. The spring passes through a long hole and is hooked onto the wheel frame fixing plate by a barb. The frame is rectangular, and the wheel frame fixing plate is welded to the front of the frame. The fertilizer box is mounted on the frame. The fertilizer box is cubic, and a hexagonal shaft passes through the fertilizer box and is mounted on it. There are four gears on each drive wheel, which are installed in different positions. One gear is installed at the upper end of the wheel frame, two gears are installed in the middle of the wheel frame, one gear is installed at the lower end of the wheel frame, and one gear is installed on the hexagonal shaft. There are two chains. One chain is driven by the gear in the middle of the wheel frame and the gear at the lower end of the wheel frame, while the other chain is driven by the gear in the middle of the wheel frame and the gear on the hexagonal shaft.

[0004] The aforementioned technical solution controls the fertilization control power unit of the fertilization operation mechanism through a drive wheel to achieve fertilization. During driving, the speed control of the hexagonal shaft is achieved through the outer diameter of the drive wheel and the gear meshing ratio. However, in this technology, the corresponding gears are not replaceable or disassembled, meaning that when different transmission ratios are required, this technology cannot achieve this through gears or chains.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0039] The following will be combined with the appendix Figure 2 To be continued Figure 8 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0040] Fertilizer applicators are common fertilizer application devices in agricultural equipment. This particular fertilizer applicator is prior art, and this specification is for illustrative purposes only; however, it should not be construed as insufficient disclosure. Figure 1 As shown, generally speaking, the fertilization mechanism includes a fertilizer hopper 01 and a feeder 02. The feeder 02 includes a fertilizer control power unit 021. The fertilizer control power unit 021 is connected to a power rod 03. When the power rod 03 rotates, it drives the fertilizer control power unit 021 to rotate, and the rotation of the fertilizer control power unit 021 realizes the fertilizer dispensing process.

[0041] This utility model proposes a fertilizer application transmission mechanism for effective control of the fertilizer application control power unit. Specifically, different transmission ratios can be achieved by changing the transmission gear set to obtain different rotational outputs, thereby realizing effective control of the fertilizer application control power unit.

[0042] Specifically, the different output controls of the fertilization control power unit can be achieved by conveniently changing the transmission ratio of the fertilization transmission mechanism.

[0043] Detailed, such as Figure 2 and Figure 3As shown, the fertilizer application transmission mechanism of this utility model is configured with a chain box 11, a transmission gear set 12, a driven member 13, and a transmission chain 14. The chain box 11 has a first end and a second end arranged in the length direction; the transmission gear set 12 has a driving gear 121 and a driven gear 122, which are mutually driven and meshed and detachably assembled at the first end of the chain box 11 and located outside the chain box 11; the driven member 13 is provided at the second end of the chain box 11; the transmission chain 14 is connected to the driven gear 122 and the driven member 13 to drive the driven member 13 to rotate.

[0044] The specific chain box 11 has two ends arranged along its length, namely the first end and the second end. The chain box 11 is preferably a flat plate structure.

[0045] In one embodiment, the chain box 11 is configured to have an inner cavity 111. The inner cavity 111 extends to the first end and the second end. Specifically, the inner cavity 111 extends from one end to the other along the length direction of the chain box 11, that is, from the first end to the second end.

[0046] In detail, the chain box 11 includes a first cover plate 112 and a second cover plate 113, which together form the inner cavity 111. In one embodiment, the first cover plate 112 and the second cover plate 113 have similar structures. Taking the first cover plate 112 as an example, as... Figure 4 As shown, the first cover plate 112 has a recess 1121 and a peripheral assembly portion 1122. When the first cover plate 112 and the second cover plate 113 are closed, the recesses of the two cover plates close to form the inner cavity 111, and are assembled into a whole through the corresponding assembly portions. Preferably, in this technical solution, the entire chain box 11 can be made of a metal material, such as iron or steel, to ensure sufficient strength.

[0047] like Figure 2 and Figure 3As shown, the transmission gear set 12 has a driving gear 121 and a driven gear 122. The driving gear 121 and the driven gear 122 are mutually driven and meshed and detachably mounted on the first end of the chain box 11 and located on the outside of the chain box 11. The driving gear 121 and the driven gear 122 are meshed together, that is, when the driving gear 121 rotates, it drives the driven gear 122 to rotate. Importantly, the driving gear 121 and the driven gear 122 are detachably connected to the chain box 11, and they are located on the outside of the chain box 11. In other words, the driving gear 121 and the driven gear 122 are exposed to the environment. Thus, when different transmission ratios need to be changed, the driving gear 121 and the driven gear can be directly disassembled and their positions interchanged, thereby achieving different transmission ratios. Alternatively, the driving gear 121 and the driven gear can be directly disassembled and replaced with driving gears and driven gear sets with different transmission ratios.

[0048] Therefore, since the driving gear 121 and the driven gear 122 are exposed to the environment, disassembly and assembly are very convenient for users.

[0049] like Figure 3 and Figure 5 As shown, a first mounting shaft 123 and a second mounting shaft 124 are mounted in parallel on the chain box 11. The first mounting shaft 123 is used to mount the drive gear 121, and the second mounting shaft 124 is used to mount the driven gear 122.

[0050] In detail, the first mounting shaft 123 passes through the chain box 11 and extends to both outer sides of the chain box 11. The first end of the first mounting shaft 123 is detachably fitted with the drive gear 121 on the first outer side of the chain box 11, and the second end of the first mounting shaft 123 is located on the second outer side of the chain box 11 for assembly with an external drive wheel. The first end of the second mounting shaft 124 is located on the first outer side of the chain box 11, and the first end of the second mounting shaft 124 is detachably connected to the driven gear 122; a portion of the second mounting shaft 124 is located in the inner cavity 111 of the chain box 11 and meshes with the transmission chain 14 for transmission. Figure 2 and Figure 3 As shown in the diagram, the left side is the first outer side, and the right side is the second outer side.

[0051] In order to assemble the first mounting shaft 123 and the second mounting shaft 124 with the chain box 11, bearings are respectively provided at the two cover plates of the chain box 11. Then, the first mounting shaft 123 and the second mounting shaft 124 can be assembled by passing through the corresponding bearings.

[0052] The first mounting shaft 123 has a first end extending to a first outer side and a second end extending to a second outer side. This allows the first mounting shaft 123 to be assembled with the driving gear 121 from the first outer side. The first end of the second mounting shaft 124 extends to the first outer side for detachable assembly with the driven gear 122. A portion of the second mounting shaft 124 is located within the inner cavity 111 of the chain box 11 for easy engagement with the transmission chain 14. Specifically, a toothed first chain disc 1241 is provided outside the portion of the second mounting shaft 124 located within the chain box 11. The transmission chain 14 meshes with this gear for easy transmission connection.

[0053] In one specific embodiment, to better facilitate the direct replacement of the driving gear 121 and the driven gear 122, the portions of the first mounting shaft 123 and the second mounting shaft 124 located on the first outer side can be set to have the same shape and size. This allows for quick installation when the driving gear 121 and the driven gear 122 need to be swapped, reducing unnecessary assembly structure adaptations. The assembly of the driving gear 121 and the driven gear 122 with their corresponding mounting shafts can be achieved using existing gear assembly methods, which will not be elaborated upon in this embodiment.

[0054] like Figure 3 and Figure 6 As shown, the driven member 13 is located at the second end of the chain box 11. Specifically, the driven member 13 is mounted on the two cover plates of the chain box 11 via bearings. More specifically, the driven member 13 is arranged parallel to the first mounting shaft 123 and the second mounting shaft 124. A second chain disc 132 is provided in the portion of the driven member 13 located within the inner cavity 111 of the chain box 11. This second chain disc 132 is parallel to the first chain disc 1241 and arranged in the same plane. The corresponding drive chain 14 engages with the first chain disc 1241 and the second chain disc 132 for transmission.

[0055] In actual operation, the drive gear 121 rotates, driving the driven gear 122 to rotate. When the driven gear 122 rotates, it drives the first chain disk 1241 to rotate. The first chain disk 1241 drives the second chain disk 132 to rotate through the transmission chain 14. The second chain disk 132 drives the driven member 13 to rotate.

[0056] Detailed, such as Figure 7 As shown, the driven member 13 has a sleeve hole 131 arranged coaxially with its rotation axis, and the transmission rod 21 is sleeved in the sleeve hole 131 to achieve transmission connection. In specific application, the transmission rod is inserted into the sleeve hole 131 to achieve power transmission. Preferably, the sleeve hole 131 is a hexagonal hole, and the part of the transmission rod 21 that is used for transmission engagement with the sleeve hole 131 is a hexagonal shaft structure.

[0057] Detailed, such as Figure 2 and Figure 3 As shown, the fertilizer application transmission mechanism also includes an assembly plate 15, a crossbar 16, and an adjusting rod 17. The crossbar 16 is fixed to the assembly plate 15 at a set angle. The lower end of the adjusting rod 17 is pivotally connected to the chain box 11, and the other end is slidably sleeved with the crossbar 16. A spring 18 is sleeved on the adjusting rod 17, and the spring 18 is located between the chain box 11 and the crossbar 17 to provide elastic buffering force. Specifically, when the chain box 11 is subjected to upward force, it moves in the direction of compressing the spring 18, at which time the spring 18 generates a downward elastic force on the chain box. When the chain box is subjected to downward force, it pulls the adjusting rod 17 downward. This technology is mainly designed to adapt to uneven ground when the chain box 11 is used in conjunction with the drive wheel, so as to achieve buffering. Preferably, the crossbar 16 is arranged horizontally; the crossbar 16 is arranged perpendicularly to the assembly plate 15.

[0058] In summary, the technical solution of this utility model allows users to easily change the position of the drive gear 121 and driven gear 122 located on the outside of the chain box 11, thereby changing the transmission ratio and enabling different fertilization controls for the fertilization device.

[0059] Example 2

[0060] like Figure 8 As shown, this utility model also proposes a fertilization device, including at least two fertilization mechanisms 2 arranged along a straight line; the fertilization device also includes a transmission rod 21, a fertilization transmission mechanism 4, and a drive wheel 3. The specific structure of the fertilization transmission mechanism is the same as that in Embodiment 1, and will not be described in detail in this embodiment.

[0061] The transmission rod 21 is connected to the driven member 13 of the fertilization transmission mechanism and to the fertilization control power unit of the at least two fertilization mechanisms 2; the drive wheel 3 is coaxially connected to the drive gear 121; when the transmission rod 21 rotates, the driven member 13 follows and drives the fertilization control power unit of the at least two fertilization mechanisms 2 to work to realize the fertilization operation.

[0062] Specifically, the drive wheel 3 is coaxially connected to the drive gear 121 via a first mounting shaft 123. That is, the drive wheel 3 is mounted on the second end of the first mounting shaft 123 located on the second outer side.

[0063] In operation, the drive wheel 3 rotates along the ground. During this rotation, the drive wheel 3 drives the drive gear 121 via the first mounting shaft 123. The drive gear 121 drives the driven gear 122, which in turn drives the second mounting shaft 124, which in turn drives the first chain disc 1241. The first chain disc 1241 then drives the second chain disc 131 via the transmission chain 14. The second chain disc 131 drives the driven member 13, which in turn drives the transmission rod 21. The transmission rod 21, during its rotation, drives the fertilization control power unit to rotate, thereby controlling the fertilization process.

[0064] In detail, the core of this technical solution is to detachably assemble the drive gear 121 and the driven gear 122 on the outside of the chain box 11. This makes it convenient for users to swap the positions of the drive gear 121 and the driven gear 122 or replace them directly to adapt to different transmission ratios, thereby ensuring the fertilization control requirements of the fertilization mechanism.

[0065] Example 3

[0066] This embodiment proposes an agricultural device, including a walking device and a working mechanism, wherein the working mechanism is a fertilization device as described in Embodiment 2. The walking device can be, for example, a tiller, a micro-tiller, an automatic tractor, or a manual tractor. The working mechanism is mounted on the walking device. In operation, the walking device moves, driving the working mechanism along with it, and the working mechanism performs automatic fertilization during the movement.

[0067] In detail, the key technical feature of this embodiment is the adoption of the fertilization device of Embodiment 2. The core feature is that the driving gear 121 and the driven gear 122 are detachably assembled on the outside of the chain box 11. This allows the user to easily interchange or directly replace the driving gear 121 and the driven gear 122 to adapt to different transmission ratios, thereby ensuring the fertilization control requirements of the fertilization mechanism.

[0068] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
