[0046] The following will be combined with the appendix Figure 1 To be continued Figure 11 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.

[0047] This utility model proposes a fertilization and sowing module and a simplified fertilization and sowing device. The simplified fertilization and sowing device includes a walking mechanism and a fertilization and sowing module. The fertilization and sowing module is detachably assembled with the walking mechanism. When the walking mechanism moves, it drives the fertilization and sowing module to move synchronously, achieving automatic fertilization and sowing during the movement. The walking mechanism can be a tiller, a micro-tiller, or a tractor. For example, when the walking mechanism is a tractor, the fertilization and sowing module is mounted on the tractor and moves synchronously with the tractor.

[0048] In one specific embodiment, the walking mechanism can be a self-propelled device. That is, the walking mechanism has its own driving power, which drives the walking mechanism automatically, thereby moving the fertilization and sowing module. This walking mechanism can be, for example, a diesel tractor or an electric self-propelled vehicle. Of course, in addition to being a power unit, the walking mechanism can also be a non-powered mechanism, such as being driven by human hands or livestock (such as cattle).

[0049] Detailed, such as Figure 1 and Figure 2 The fertilization and sowing module of this utility model includes a mounting truss 10, at least one sowing device 20, a number of fertilization devices 30 equal to the number of sowing devices 20, and a fertilization floating device 40. The at least one sowing device 20 and the number of fertilization devices 30 equal to the number of sowing devices 20 are all mounted on the mounting truss 10.

[0050] In detail, in one specific embodiment, such as Figure 3 The mounting truss 10 shown is a strip-shaped tubular structure, such as a square tube. During assembly, at least one seeding device 20, an equal number of fertilizer application devices 30, and a fertilizer floating device 40 are all assembled onto the mounting truss 10. The mounting truss 10 can be a square tube or a round tube, or a combination of square and round tube structures. This design does not impose many restrictions on the mounting truss 10; anything that allows assembly is acceptable. Furthermore, the mounting truss 10 is not limited to a straight tube structure; for example... Figure 4 As shown, it can also be a stepped tube or any other suitable shape. Any technical solution that merely changes the shape of the mounting truss 10 should fall within the protection scope of this utility model.

[0051] The number of fertilization devices 30 and seeding devices 20 is selected based on the actual conditions of the hilly terrain. That is, it can include one set of fertilization devices 30 and one or more sets of seeding devices 20. Preferably, in one embodiment, such as... Figure 1 and Figure 2 As shown, the system includes two seeding devices 20 and two fertilizer application devices 30; along the length of the mounting truss 10, the two seeding devices 20 are located between the two fertilizer application devices 30; the fertilizer floating device 40 is located between the two seeding devices 20. This layout enables simultaneous seeding and fertilization operations in two rows, and is also suitable for the needs of mountainous and hilly terrain.

[0052] Detailed as Figure 5As shown, each of the seeding devices 20 includes a frame 201, a seeding mechanism 202 mounted on the frame 201, and a four-bar linkage 203 connected to the front side of the frame 201. The four-bar linkage 203 is detachably mounted on the mounting truss 10.

[0053] Specifically, during assembly, the four-bar linkage 203 is simply assembled onto the mounting truss 10.

[0054] like Figure 5 and Figure 6 As shown, the frame 201 has a through-hole 2011 extending through both sides, and an assembly crossbar 2012 is located above the through-hole 2011. The sowing mechanism 202 includes a seed metering device 2021 and a seed box 2022. The seed metering device 2021 forms a slot 2023. The assembly crossbar 2012 is installed in the slot 2023 to fix the entire sowing mechanism 202. The seed metering device 2021 passes through the through-hole 2011, and the seed box 2022 is located above the assembly crossbar 2012. The frame 201 also includes a front vertical bar 2013, a rear vertical bar 2014, and a bottom support bar 2015. The assembly crossbar 2012, the front vertical bar 2013, the rear vertical bar 2014, and the bottom support bar 2015 are used to form a rectangular frame structure.

[0055] In this design, the entire sowing mechanism 202 is attached to the assembly crossbar 2012 via the slot 2023. This method ensures the ease of assembly and disassembly of the sowing mechanism 202.

[0056] Specifically, such as Figure 7 As shown in this embodiment, the seed metering device 2021 is configured to have a seed metering device body 20211, a connecting part 20212, and an upper support part 20212. The slot 2023 is located between the seed metering device body 20211 and the upper support part 20212, and the connecting part 20212 is directly opposite the slot 2023. The seed metering device body 20211, the connecting part 20212, and the upper support part 20212 are an integral structure. Of course, the seed metering device 2021 and the seed box 2022 can be implemented using existing technology, that is, the structure of the seed metering device 2021 and the seed box 2022 can be an existing seed metering structure and seed box design. One of the key points of this solution is that the seed metering device body 20211, the connecting part 20212, and the upper support part 20212 are designed as an integral unit, which meets the requirement of quick assembly and disassembly.

[0057] like Figure 7As shown, the slot 2023 is open on one side in the lateral direction to facilitate the insertion of the assembly crossbar 2012 into the slot 2023. That is, the mounting truss 10 can be inserted into the slot 2023 in a straight line from the left side of the slot 2023. This facilitates the assembly of the sowing mechanism 202.

[0058] Specifically, the outer shell of the seed metering device body 20211, the connecting part 20212, and the upper support part 20212 is an integral structure. The slot 2023 is formed on the side of the connecting part 20212. The connecting part 20212 is connected to the assembly crossbar 2012. More specifically, the connecting part 20212 and the assembly crossbar 2012 can be detachably assembled, for example, by bolt connection. Bolt through holes are provided at corresponding positions on the connecting part 20212 and the assembly crossbar 2012; during assembly, bolts are passed through the corresponding bolt through holes to assemble the assembly crossbar 2012 with the connecting part 20212.

[0059] In addition, in order to provide sufficient support for the sowing mechanism 202 by the frame 201, a support part 2026 is provided on the bottom support rod 2015 of the frame 201. The support part 2026 contacts the seed metering device 2021 to support the seed metering device 2021, so that the force of the sowing mechanism 202 can be effectively distributed on the entire frame 201.

[0060] A depth-limiting wheel 60 is connected to the rear side of the frame 201. Specifically, the depth-limiting wheel 60 is assembled and connected to the frame 201 via a bracket 70. The depth-limiting wheel 60 ensures the movement of the sowing device and prevents it from sinking too deeply into the soil, thus ensuring that the sowing device is positioned appropriately above the ground. To further facilitate the movement of the depth-limiting wheel 60, radially outward-extending insertion pieces 601 are provided on both sides of the depth-limiting wheel 60. During the movement of the depth-limiting wheel 60, these insertion pieces 601 will insert into the ground, ensuring effective movement of the depth-limiting wheel 60 and preventing slippage. Specifically, the depth-limiting wheel 60 is drivenly connected to the seed metering device 2021. Specifically, as... Figure 11 As shown, the driving sprocket 602 of the depth limiting wheel 60 is connected to the driven sprocket 20211 of the seed metering device 2021 via a transmission chain 70. When the depth limiting wheel 60 rolls along the ground, its driving sprocket 602 rotates accordingly. The driving sprocket 602 drives the driven sprocket 20211 to rotate via the transmission chain 70. The rotation of the driven sprocket 20211 controls the sowing process of the seed metering device.

[0061] The four-bar linkage 203 includes a first connector 2031, a second connector 2032, and a first link 2033 and a second link 2034, both hinged to the first connector 2031 and the second connector 2032 respectively. The first link 2033 and the second link 2034 are arranged in parallel. The first link 2033, the second link 2034, the first connector 2031, and the second connector 2032 form a parallelogram, that is, a four-bar linkage structure.

[0062] The first connecting member 2031 is fixed to the frame 201; the second connecting member 2032 has a connection structure for detachable connection with the mounting truss 10; a tension spring 2035 is connected to the first link 2033 and the second link 2034, which causes the first connecting member 2031 to have a downward torque relative to the second connecting member 2032. The first connecting member 2031, the second connecting member 2032, the first link 2033, and the second link 2034 constitute a four-bar linkage. The tension spring 2035 generates a downward torque relative to the second connecting member 2032 on the entire four-bar linkage. This helps to ensure that the entire sowing mechanism 202 generates a downward torque so that the sowing mechanism 202 can make better contact with the ground and avoid the sowing mechanism 202 jumping off when encountering a protrusion during operation.

[0063] Specifically, such as Figure 5 The connecting structure shown is located above the two connecting rods. This structure includes a first locking member 20341 fixedly connected to the second connecting member 2032 and a second locking member 20342 pivotally connected to the second connecting member. When the second locking member 20342 rotates to mate with the first locking member 20341, it forms a locking space 20343 for assembly with the walking mechanism. The first locking member 20341 and the second locking member 20342 are locked or unlocked by a locking member 20344. The shape of the locking space 20343 is adapted to the shape of the connection position of the walking mechanism. The locking member 20344 can be, for example, a bolt structure. That is, the first locking member 20341 and the second locking member 20342 are locked or unlocked by a bolt structure.

[0064] like Figure 1 and Figure 2The embodiment shown includes two fertilizer applicators 30. The two fertilizer applicators 30 are located on opposite sides and are assembled and connected to the mounting truss 10. Each fertilizer applicator 30 includes a fertilizer hopper 301 and a feeder 302. Both the fertilizer hopper 301 and the feeder 302 can be implemented using existing technology. The feeder 302 includes a fertilizer control power unit (not shown in the figure). The fertilizer control power unit is connected to a transmission rod. When the transmission rod rotates, it drives the fertilizer control power unit to rotate, and the rotation of the fertilizer control power unit achieves fertilizer application. The fertilizer control power unit is a built-in control structure of the feeder 302 and is considered existing technology.

[0065] like Figure 8 The fertilization floating device 40 shown includes a drive wheel 401, a fertilization transmission mechanism 402, and a transmission rod 403. The drive wheel 401 is driven by the active end of the fertilization transmission mechanism 402, and the output end of the fertilization transmission mechanism 402 is driven by the transmission rod 403. The transmission rod 403 is connected to the fertilization control power unit of each fertilization device 30 and drives the fertilization control power unit to work when the transmission rod 403 is driven to rotate. In specific operation, the drive wheel 401 is in contact with the ground and rolls with the movement of the walking mechanism. During the rolling process of the drive wheel 401, it drives the fertilization transmission mechanism 402 to move, which in turn drives the transmission rod 403 to rotate. When the transmission rod 403 rotates, it drives the fertilization control power unit of the feeder 302 to rotate, thereby realizing the driving of the fertilization action.

[0066] Very important, such as Figure 9 and Figure 10The fertilizer application transmission mechanism 402 shown includes a chain box 4021, a transmission gear set 4022, a driven member 4023, and a transmission chain 4024. The chain box 4021 has a first end and a second end arranged along its length; the transmission gear set 4022 has a driving gear 40221 and a driven gear 40222, which are mutually driven and meshed and detachably assembled at the first end of the chain box 4021 and located outside the chain box 4021; the driven member 4023 is located at the second end of the chain box 4021; the transmission chain 4024 is drivenly connected to the driven gear 40222 and the driven member 4023 to drive the driven member 4023 to rotate; the driven member 4023 is drivenly assembled to the transmission rod 403; the drive wheel 401 is drivenly connected to the driving gear 40221; the chain box 4021 is mounted on the mounting truss 10 via a mounting bracket 404. In operation, the drive wheel 401 rolls along the ground, driving the drive gear 40221 to rotate. This drive gear 40221 then drives the driven gear 40222 to rotate. The driven gear 40222, through the transmission chain 4024, drives the transmission component 4023 to rotate. The transmission component 4023 drives the transmission rod 403 to rotate, which in turn drives the fertilizer control power unit of the feeder 302, thus achieving the fertilization effect. Importantly, in this embodiment, the drive gear 40221 and the driven gear 40222 are detachably mounted on the outside of the chain box 4021. When the transmission ratio of the drive gear and driven gear needs to be changed, the drive gear 40221 and driven gear 40222 can be disassembled and their positions swapped, or a gear combination with a different transmission ratio can be used. This design allows users to easily change the transmission ratio of the drive gear and driven gear according to their needs in agricultural operations.

[0067] In one specific embodiment, the chain box 4021 has an inner cavity 40211, within which the transmission chain 4024 is located. This helps protect the transmission chain 4024 from external foreign objects affecting its meshing with the corresponding driven member 4023 and driven gear 40222. Of course, the driven member 4023 and driven gear 40222 can be equipped with corresponding chain discs, and power transmission is achieved through the meshing of the transmission chain 4024 with the chain discs.

[0068] The driven member 4023 is provided with a sleeve hole (not shown in the figure); the transmission rod 403 is sleeved in the sleeve hole to realize the transmission connection with the driven member 4023.

[0069] See Figure 8 and Figure 9As shown, the mounting bracket 404 has a rearward-facing crossbar 4042. An adjusting rod 405 is provided between the chain box 4021 and the crossbar 4042. The lower end of the adjusting rod 405 is pivotally connected to the chain box 4021, and the other end is slidably sleeved with the crossbar 4042. A spring 406 is sleeved on the adjusting rod 405. The spring 406 is located between the chain box 4021 and the crossbar 4042 to provide elastic buffering force. However, when the drive wheel 401 encounters unevenness during rolling, the entire fertilization transmission mechanism and the drive wheel 401 move upward and downward as a whole. During the upward and downward movement, the adjusting rod 405 can slide up and down along the crossbar 4042. When moving upward, it compresses the spring 406, which exerts downward pressure on the drive wheel 401, ensuring that the drive wheel 401 maintains good contact with the ground.

[0070] In summary, the technical solution of this utility model integrates a modular seeding device and a fertilizing device, and can be assembled in different quantities according to different needs, making it suitable for applications in hilly and mountainous areas. Furthermore, the modular seeding device design facilitates simple and rapid assembly. The externally mounted driving and driven gears of the floating fertilizing device 40 allow for convenient changes in the transmission ratio to meet different operational requirements.

[0071] Example 2

[0072] This utility model also proposes a lightweight and simplified fertilization and sowing device, including a walking mechanism and a fertilization and sowing operation module, wherein the fertilization and sowing operation module is the fertilization and sowing operation module described in Embodiment 1.

[0073] The fertilization and sowing module is detachably assembled with the walking mechanism. When the walking mechanism moves, it drives the fertilization and sowing module to move synchronously, enabling automatic fertilization and sowing during the movement. The walking mechanism can be a tiller, a micro-tiller, or a tractor. For example, when the walking mechanism is a tractor, the fertilization and sowing module is mounted on the tractor and moves synchronously with it. The modular integration of the sowing and fertilization devices, and the ability to assemble different quantities according to different needs, adapts to hilly and mountainous terrain. Furthermore, the modular design of the sowing device facilitates simple and quick assembly. The externally mounted drive and driven gears of the fertilization floating device 40 allow for convenient changes in the transmission ratio to meet different operational requirements.

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.
