Description

Technical Field

[0001] This utility model relates to the field of sowing equipment technology, and in particular to a sowing device and agricultural operation equipment. Background Technology

[0002] Seeders for mountainous and hilly areas are agricultural machines specifically designed for sowing operations on complex terrains such as slopes, hills, and terraces. Because of the undulating terrain and complex soil conditions in mountainous and hilly areas, traditional seeders are ill-suited to these conditions, necessitating seeders with specialized functions and designs to complete the work.

[0003] Seeders designed for hilly and mountainous areas need a simplified structure for ease of use, assembly, and disassembly. However, existing hilly seeders still use the layout of traditional seeders, resulting in a complex structure and inconvenient assembly and disassembly.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a seeding device and agricultural operation equipment, which aims to simplify the structure of the seeder and achieve quick assembly and disassembly.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0007] A seeding device, configured to have:

[0008] The frame has a through-hole on both sides and a crossbar above the through-hole.

[0009] A seeding mechanism includes a seed metering device and a seed box that are integrally set together, wherein the seed metering device has a slot;

[0010] The assembly crossbar is installed in the slot to fix the entire sowing mechanism;

[0011] The seed metering device is inserted through the assembly through hole, and the seed box is located above the assembly crossbar.

[0012] Furthermore, the seed metering device is configured to have a seed metering device body, a connecting part, and an upper support part, with the slot located between the seed metering device body and the upper support part, and the connecting part facing the slot.

[0013] Furthermore, the seed metering device, the connecting part, and the upper support part are an integral structure, and the seed box is assembled on the upper support part.

[0014] Furthermore, the connecting part is detachably assembled with the assembly crossbar.

[0015] Furthermore, the slot is open on one side in the lateral direction to facilitate the insertion of the assembly crossbar into the slot.

[0016] Furthermore, the front end of the frame is connected to a four-bar linkage mounting mechanism to achieve a detachable connection with the walking mechanism.

[0017] Furthermore, the four-bar linkage includes a first connector, a second connector, and a first link and a second link, which are respectively hinged to the first connector and the second connector at both ends, and the first link and the second link are arranged in parallel.

[0018] The first connector is fixed to the frame; the second connector has a connection structure for detachable connection with the walking mechanism; a tension spring is connected to the first link and the second link, which causes the first connector to have a downward torque relative to the second connector.

[0019] Furthermore, the connecting structure is located above the two connecting rods. The connecting structure includes a first locking member fixedly connected to the second connecting member and a second locking member pivotally connected to the second connecting member. When the second locking member rotates to mate with the first locking member, it forms a locking space for assembly with the walking mechanism. The first locking member and the second locking member are locked or unlocked by a locking member.

[0020] Furthermore, a depth-limiting wheel is connected to the rear side of the frame, and the driving sprocket of the depth-limiting wheel is connected to the driven sprocket of the seed metering device via a transmission chain.

[0021] Another aspect of this utility model provides an agricultural operation device, including a walking mechanism and at least one set of seeding devices, wherein the at least one set of seeding devices is detachably assembled and connected to the walking mechanism; the seeding device is any of the seeding devices described above.

[0022] The beneficial effects of this utility model are:

[0023] The present invention provides a sowing device configured with a frame and a sowing mechanism. The frame has a through-hole extending through both sides, and an assembly crossbar is located above the through-hole. The sowing mechanism includes a seed metering device and a seed box, both integrally formed, with the seed metering device forming a slot. The assembly crossbar is installed at the slot to fix the entire sowing mechanism. The seed metering device passes through the through-hole, and the seed box is located above the assembly crossbar. In this solution, the sowing device achieves quick assembly by using the slot formed by the integrated seed metering device and seed box structure to match the assembly crossbar, simplifying the structure of the sowing device and facilitating its disassembly and use.

[0030] The following will be combined with the appendix Figure 1 To be continued Figure 6 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.

[0031] like Figure 1 and Figure 2 As shown, this utility model proposes a sowing device, which is configured to have a frame 10 and a sowing mechanism 20. The frame 10 is used to support the sowing mechanism 20 and for assembly and connection with a walking mechanism.

[0032] Specifically, the frame 10 has a through-hole 101 extending through both sides, and an assembly crossbar 102 is located above the through-hole 101. The sowing mechanism 20 includes a seed metering device 201 and a seed box 202, both of which are integrally structured. The seed metering device 201 has a slot 203. The assembly crossbar 102 is installed in the slot 203 to fix the entire sowing mechanism 20. The seed metering device 201 passes through the through-hole 101, and the seed box 202 is located above the assembly crossbar 102. In particular, the seed metering device 201 is an integral structure, which facilitates the assembly and fixation of the entire sowing device.

[0033] In this technical solution, during assembly, the seeding mechanism 20 only needs to be hung on the assembly crossbar 102 of the frame 10 to achieve assembly connection. When disassembly is required, the entire seeding mechanism 20 can be removed from the assembly crossbar 102. This technical layout greatly facilitates the customer's assembly, maintenance, and transportation needs.

[0034] In detail, the sowing mechanism 20 is an integral structure, with the seed box 202 assembled on the seed metering device 201 to form the integral structure. It can be completely disassembled and assembled during disassembly and assembly; during transportation, the sowing mechanism 20 can be disassembled and transported as a whole, making it convenient for users to carry the sowing mechanism 20 and frame 10 separately, especially suitable for mountainous and hilly areas. It is also very convenient for various maintenance and replacement procedures.

[0035] It should be understood that in this solution, the seed metering device 201 is a structural implementation of existing technology. For example, it can be a pneumatic seed metering device with a replaceable seed tray to adapt to different sowing needs. This pneumatic seed metering device includes a sprocket 2011 for transmission. In actual operation, the sowing of the pneumatic seed metering device can be controlled by controlling the sprocket 2011.

[0036] The seed box 202 is located above the seed metering device 201 and is used to provide seeds to the seed metering device 201. The seed box 202 and the seed metering device 201 can be a fixed integrated structure or a separate structure. When a separate structure design is adopted, the seed box 202 and the seed metering device 201 can be disassembled and assembled. For example, assembly can be achieved by means of screws or other structures.

[0037] Specifically, such as Figure 4 The seed metering device 201 shown is configured with a seed metering device body 205, a connecting part 204, and an upper support part 206. A slot 203 is located between the seed metering device body 205 and the upper support part 206, and the connecting part 204 is directly opposite the slot 203. The seed metering device 201, the upper support part 206, and the connecting part 204 are an integral structure. The slot 203 formed in the seed metering device 201 allows the entire sowing mechanism 20 to be mounted on the assembly crossbar 102 of the frame 10. This method makes assembly simpler and faster. It should be noted that in this embodiment, the seed metering device 201 and the seed box 202 are implemented using existing technology.

[0038] The slot 203 is a straight groove, meaning it runs along the front-to-back direction. The slot 203 extends through the entire length of the machine, and has an open side in the lateral direction to facilitate the insertion of the assembly crossbar 102 into it. Figure 4As shown, the slot 203 is open on the left side. During assembly, the left open position of the slot 203 of the seeding mechanism 20 is aligned with the assembly crossbar 102, and then the assembly crossbar 102 is engaged into the slot 203. This method is simple and quick to operate.

[0039] In addition, in one embodiment, after the assembly crossbar 102 is inserted into the slot 203 and the connecting part 204, the assembly crossbar 102 is located at the middle position of the sowing mechanism 20 in the lateral direction, thus ensuring the stability of the sowing mechanism when it is hung on the assembly crossbar 102.

[0040] Specifically, the connecting part 204 is detachably connected to the mounting crossbar 102. That is, the connecting part 204 secures the entire sowing mechanism 20 to the frame 10. In a specific embodiment, the connecting part 204 and the mounting crossbar 102 can be connected by bolts. Specifically, corresponding bolt holes are provided on the connecting part 204 and the mounting crossbar 102, and then the two are connected together by a screw. Of course, any other suitable connection and assembly method can be used, as long as detachable assembly is achieved. For better assembly, when the mounting crossbar 102 is placed in the slot 203 and the upper surface of the mounting crossbar 102 contacts the top of the slot 203, the corresponding bolt holes of the mounting crossbar 102 and the connecting part 204 are at the same height, so only the position of the sowing mechanism 20 in the front-back direction needs to be adjusted.

[0041] In one specific embodiment, the shape of the surface of the connecting portion 204 facing the slot 203 is the same as the shape of the surface of the assembly crossbar 102 facing the connecting portion 204, for example, both are planar.

[0042] Furthermore, to better support the sowing mechanism 20, the bottom of the mounting through hole 101 of the frame 10 has a support portion 103 that matches the lower shape of the sowing mechanism 20. When assembling the sowing mechanism 20, the mounting crossbar 102 is fitted onto the corresponding slot 203, and the lower part of the sowing mechanism 20 is positioned at the support portion 103. At this time, both the support portion 103 and the mounting crossbar 102 can support the entire sowing mechanism 20. Simultaneously, when the sowing mechanism 20 is precisely inserted into the mounting through hole 101, the corresponding connecting portion 204 aligns perfectly with the bolt holes of the mounting crossbar 102. Therefore, this technical solution can improve assembly efficiency and reduce assembly complexity.

[0043] In one specific embodiment, such as Figure 3The frame 10 shown is a rectangular frame structure. A front vertical bar 104 and a rear vertical bar 105 are fixedly connected to both ends of the assembly crossbar 102. A bottom support bar 106 is connected to the lower ends of the front vertical bar 104 and the rear vertical bar 105. The assembly crossbar 102, the front vertical bar 104, the rear vertical bar 105, and the bottom support bar 106 form the frame 10. The assembly crossbar 102, the front vertical bar 104, the rear vertical bar 105, and the bottom support bar 106 are preferably made of metal materials to ensure sufficient strength; for example, they can be made of iron, steel, or aluminum. The support part 103 is located on the bottom support bar 106. A seeding and furrowing device 60 is mounted on the lower part of the bottom support bar 106. The seeding and furrowing device 60 is used to create furrows in the land. The seeding and furrowing device 60 preferably adopts an adjustable height structure. Specifically, the seeding and furrowing device 60 can be implemented using existing structures, which will not be elaborated in this embodiment.

[0044] In detail, in some embodiments, the front end of the frame 10 is connected to a four-bar linkage 30 to achieve a detachable connection with the walking mechanism. This four-bar linkage 30 is used for detachable assembly with, for example, a tractor, enabling modularity and fulfilling the function of a replaceable module design.

[0045] Detailed, such as Figure 5 The four-bar linkage 30 shown includes a first connecting member 301, a second connecting member 302, and a first connecting rod 303 and a second connecting rod 304, both ends of which are respectively hinged to the first connecting member 301 and the second connecting member 302. The first connecting rod 303 and the second connecting rod 304 are arranged in parallel. The first connecting member 301 is fixed to the frame 10. The second connecting member 302 has a connecting structure 306 for detachable connection with the walking mechanism. Tension springs 305 are connected to the first connecting rod 303 and the second connecting rod 304, and the tension springs 305 give the first connecting member 301 a downward torque relative to the second connecting member 302. This four-bar linkage 30 achieves buffering between the entire sowing device and the walking mechanism, avoiding rigid force transmission and ensuring the stability of the sowing device during operation.

[0046] The first connector 301 includes two opposing clamping parts 3011, which are clamped and fixed to the front vertical bar 104 of the frame 10.

[0047] To ensure the stability of the four-bar linkage 30, each of the first link 303 and the second link 304 comprises two links, which are respectively clamped and hinged to the first connector 301 and the second connector 302. Each pair of first and second links is arranged in parallel and adopts the same structure.

[0048] The connecting structure 306 is located above the two connecting rods. This connecting structure 306 is used to assemble with the traveling mechanism to link the seeding device with the traveling mechanism.

[0049] In detail, the connection structure 306 includes a first locking member 3061 fixedly connected to the second connecting member 302 and a second locking member 3062 pivotally connected to the second connecting member 302. When the second locking member 3062 rotates to mate with the first locking member 3061, it forms a locking space 3063 for assembly with the walking mechanism. The first locking member 3061 and the second locking member 3062 are locked or unlocked by a locking member 3064. Figure 4 As shown, the first locking member 3061 includes a vertical portion 30611 and a rotating portion 30612 pivotally connected to the vertical portion 30611. When the rotating portion 30612 and the second locking member 3062 are brought together and closed, the locking space 3062 is formed. The locking member 3064 can lock the rotating portion 30612 and the second locking member 3062. Specifically, the locking member 3064 can be, for example, a bolt structure, including a stud and a nut, with the stud passing through the second locking member 3062 and the rotating portion 30612 and then locked by the nut. This technical solution enables rapid locking assembly with the crossbeam of the traveling mechanism.

[0050] like Figure 1 and Figure 2 As shown, a depth-limiting wheel 40 is connected to the rear side of the frame 10. Specifically, the depth-limiting wheel 40 is assembled and connected to the frame 10 via a bracket 50. The depth-limiting wheel 40 ensures the movement of the sowing device and prevents it from sinking too deeply into the soil, thus ensuring that the sowing device is placed in a suitable position above the ground. To facilitate the movement of the depth-limiting wheel 40, radially outward-extending inserts 401 are provided on both sides of the depth-limiting wheel 40. During the movement of the depth-limiting wheel 40, these inserts 401 will insert into the ground, ensuring the effective movement of the depth-limiting wheel 40 and preventing slippage. In detail, the driving sprocket 402 of the depth-limiting wheel 40 is connected to the driven sprocket 2011 of the seed metering device 201 via a transmission chain 50. When the depth-limiting wheel 40 rolls along the ground, the driving sprocket 402 of the depth-limiting wheel 40 rotates accordingly. The driving sprocket 402 drives the driven sprocket 2011 to rotate via the transmission chain 50. The rotation of the driven sprocket 2011 enables seeding control of the seed metering device.

[0051] Example 2

[0052] like Figure 6As shown, another aspect of this utility model proposes an agricultural operating device, including a walking mechanism and at least one set of seeding devices 100, which are detachably connected to the walking mechanism; the seeding devices 100 are any of the seeding devices described in Embodiment 1. The seeding devices of this agricultural operating device can be quickly disassembled and assembled, which is beneficial for operating needs in hilly and mountainous areas. Specifically, during assembly, the seeding devices 100 are mounted on a crossbar 200 via a four-bar linkage; the crossbar 200 is used for fixed connection with the walking mechanism. Of course, the walking mechanism can be, for example, a micro-tiller, a tractor, or other agricultural equipment.
