Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a seeding opening and closing mechanism and a triangular seeder. Background Technology

[0002] The function of a triangular seeder (seeder) is to evenly sow crop seeds into furrows of a certain depth at a specific seed rate or plant spacing, cover them with an appropriate amount of fine, moist soil, and compact them appropriately, providing favorable conditions for seed germination to achieve high and stable yields, improve labor productivity in sowing operations, and reduce the labor intensity of users. Existing seeders mainly consist of a main frame, wheels, furrowing device, seed metering device, transmission mechanism, soil covering and compaction device, and fertilization mechanism.

[0003] Current seeders use drive wheels, which transmit power to the fertilization and seeding devices via a transmission system. To improve efficiency, multiple seeding units are typically installed, each capable of sowing one row of seeds per round trip. However, in the final stages of sowing in each plot, some remaining land cannot be sown by the seeder. In such cases, manual sowing is often necessary, hindering the improvement of agricultural mechanization efficiency. Utility Model Content

[0004] This utility model provides a sowing opening and closing mechanism and a triangular-shaped seeder, which can open and close the sowing components during the sowing process, so that the seeder can still sow the remaining ground in the final stage of sowing, thereby improving the efficiency of mechanized operations.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A seeding start-up and shut-down mechanism for starting and stopping the seeding assembly;

[0007] The device includes an opening and closing assembly, which includes a transmission wheel and a transmission disc arranged opposite to each other. A secondary stop is provided on one side of the transmission wheel, and a main stop is provided on one side of the transmission disc.

[0008] The transmission disc is used to connect to the first transmission shaft of the seeding assembly, and the transmission wheel is used to connect to the second transmission shaft of the seeding assembly.

[0009] When the main stop and the auxiliary stop are in contact, the first drive shaft can drive the second drive shaft to rotate, thereby activating the sowing assembly; when the main stop and the auxiliary stop are separated, the first drive shaft and the second drive shaft are disconnected, thereby shutting down the sowing assembly.

[0010] As a further improvement, the main stop member is movably connected to the transmission disc, so that the main stop member can be moved to a position that interferes with or does not interfere with the secondary stop member;

[0011] Alternatively, the secondary stopper can be movably connected to the transmission wheel, allowing the secondary stopper to be moved to a position that interferes with or does not interfere with the main stopper.

[0012] As a further improvement, when the main stop member is movably connected to the transmission disk, a stop block is also provided on the side of the transmission disk where the main stop member is located; the stop block is set off from the active center of the main stop member.

[0013] As a further improvement, a movable limiting rod is also connected to the transmission disc, and the main stop can be moved to the side where the limiting rod is away from the transmission wheel.

[0014] As a further improvement, the limiting rod is connected to an elastic element, and the other end of the elastic element is connected to the transmission disc.

[0015] As a further improvement, a connecting member is connected to the limiting rod, and the connecting member is connected to the transmission disc.

[0016] As a further improvement, the connector is elastic.

[0017] As a further improvement, the connector and the transmission disk are rotatably connected via a connecting shaft.

[0018] As a further improvement, a torsion spring is connected to the connecting shaft, with one end of the torsion spring connected to the transmission disc and the other end connected to the connecting piece.

[0019] This utility model also provides a triangular seeder, including the aforementioned seeding opening and closing mechanism, and further including a seeding component and a power wheel, wherein the seeding component and the power wheel are both connected to the main support.

[0020] The power wheel can drive the first transmission shaft to rotate. The transmission disc is connected to the first transmission shaft of the seeding assembly, and the transmission wheel is connected to the second transmission shaft of the seeding assembly. The second transmission shaft is also connected to the seeding box transmission shaft used to drive the seeding box in the seeding assembly to rotate.

[0021] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0022] (1) A sowing opening and closing mechanism of the present invention realizes whether the first drive shaft and the second drive shaft are connected through the opening and closing component, thereby controlling the start and stop of a certain sowing component, so that the seeder can sow for plots of different sizes.

[0023] (2) The seeding opening and closing mechanism of this utility model controls the connection between the opening and closing components by adjusting the position of the main stop and the auxiliary stop, thereby controlling the connection between the first drive shaft and the second drive shaft. The structure is simple and the operation is easy.

[0024] (3) The sowing opening and closing mechanism of this utility model limits the main blocking component by a limiting component when the sowing component is closed; and blocks the main blocking component by a stop block when the sowing component is started; both of these measures ensure the stability and reliability of the mechanism.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0036] Furthermore, terms such as "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention. These terms are primarily for better describing this application and its embodiments and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation. Moreover, some of the aforementioned terms, besides indicating orientation or positional relationships, may also have other meanings; for example, the term "upper" may, in some cases, indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0038] like Figure 1 As shown, the embodiment of this invention provides a triangular seeder, which includes a seeding component 2 and a power wheel 3. Both the seeding component 2 and the power wheel 3 are connected to a main support 4, which provides support for the seeding component 2 and the power wheel 3.

[0039] The drive wheel 3 is connected to the main drive shaft 31, which in turn is connected to the sowing drive shaft 32, which is connected to the first drive shaft 21. During the sowing process, the drive wheel 3 rolls on the ground. As it rolls, power is transmitted sequentially through the main drive shaft 31, the sowing drive shaft 32, and the first drive shaft 21, ultimately driving the sowing box drive shaft 23 in the sowing assembly 2 to rotate, thus initiating the sowing process.

[0040] Alternatively, the drive shafts can be connected by transmission components. For example, the sowing drive shaft 32 and the first drive shaft 21 are connected by a first transmission component 24. The first transmission component 24 is a flexible transmission component, a common type of transmission component that is flexible or adaptable, such as a drive belt or drive chain. In this embodiment, the first transmission component 24 is used as a drive chain. Similarly, all other transmission components in this embodiment use drive chains.

[0041] To further explain, when each drive shaft is connected to the drive chain, a connecting gear is fitted on the drive shaft for engagement with the drive chain.

[0042] To enable simultaneous fertilization during sowing, achieving integrated sowing and fertilization operations, this solution also includes a fertilization component 1 mounted on the seeder above the main support 4. The fertilization component 1 contains a fertilization drive shaft, which is also driven by the power wheel 3. This fertilization drive shaft is connected to the main drive shaft 31 via a transmission chain. When the power wheel 3 rotates, it simultaneously drives the fertilization drive shaft to rotate, thereby performing fertilization.

[0043] In this solution, the seeder is equipped with two sowing components 2 to improve its operating efficiency. Each sowing component 2 can sow one row of seeds after one round trip of the seeder. Of course, other numbers of sowing components 2 can be used in other situations. However, in the final stage of sowing each plot, the remaining ground may not be able to be sown by each sowing component; the remaining ground may only accommodate one row of seeds. In this case, manually sowing the remaining ground is not conducive to improving the efficiency of agricultural mechanization. Continuing to use the seeder results in seed waste and overly dense sowing in some areas.

[0044] Therefore, this utility model also provides a sowing opening and closing mechanism, which can control the start and stop of a certain sowing component 2. In the final stage of sowing, some sowing components can be shut down according to the condition of the remaining ground, so that the seeder can continue to sow on the remaining ground.

[0045] Combination Figure 2-5As shown, this embodiment provides a sowing opening and closing mechanism for starting and closing a sowing assembly 2. It includes an opening and closing assembly 5, which comprises a transmission wheel 51 and a transmission disk 53 disposed opposite to each other. A secondary stop 52 is provided on one side of the transmission wheel 51, and a main stop 54 is provided on one side of the transmission disk 53. The transmission disk 53 is connected to the first transmission shaft 21 of the sowing assembly 2, and the transmission wheel 51 is connected to the second transmission shaft 22 of the sowing assembly 2. When the main stop 54 abuts against the secondary stop 52, the first transmission shaft 21 drives the second transmission shaft 22 to rotate, thus starting the sowing assembly 2. When the main stop 54 separates from the secondary stop 52, the first transmission shaft 21 and the second transmission shaft 22 are disconnected, thus closing the sowing assembly 2.

[0046] The drive wheel 3 is connected to the main drive shaft 31, which is connected to the sowing drive shaft 32. The sowing drive shaft 32 is connected to the first drive shaft 21, and the drive wheel 3 can drive the first drive shaft 21 to rotate. The transmission disc 53 is connected to the first drive shaft 21 of the sowing assembly 2, and the transmission wheel 51 is connected to the second drive shaft 22 of the sowing assembly 2. The second drive shaft 22 is connected to the sowing box drive shaft 23, which drives the sowing box in the sowing assembly 2 to rotate, through the second transmission component 25.

[0047] During the sowing period, each sowing assembly 2 needs to sow seeds. At this time, the positions of the main stop 54 and the secondary stop 52 interfere with each other. When the first drive shaft 21 rotates, the drive disk 53 rotates synchronously, and the main stop 54 rotates at the same time. When the main stop 54 rotates to abut against the secondary stop 52, the main stop 54 drives the secondary stop 52 to rotate, causing the drive wheel 51 and the second drive shaft 22 to rotate, thereby driving the sowing box drive shaft 23 to rotate, and the sowing assembly 2 sows seeds.

[0048] In this embodiment, the transmission wheel 51 is a gear, which is connected to the second transmission component 25, which is a transmission chain.

[0049] When it is necessary to shut down a certain seeding component 2, the main stop 54 and the auxiliary stop 52 are separated, and there is no positional interference between them. The first drive shaft 21 and the second drive shaft 22 are disconnected, and the power of the first drive shaft 21 cannot be output to the second drive shaft 22, thereby shutting down the seeding component 2.

[0050] Furthermore, combining Figure 4 and Figure 5 As shown, the main stop 54 is movably connected to the transmission disc 53, allowing the main stop 54 to be moved to a position where it interferes with or does not interfere with the secondary stop 52. Alternatively, in other embodiments, the secondary stop 52 may be movably connected to the transmission wheel 51, allowing the secondary stop 52 to be moved to a position where it interferes with or does not interfere with the main stop 54.

[0051] In this embodiment, the main stop 54 and the transmission disk 53 are movably connected. The transmission disk 53 is provided with a stop 542 on the side of the main stop 54. The stop 542 is set off from the center of motion of the main stop 54.

[0052] The sides and contact surfaces where the main stopper 54 and the auxiliary stopper 52 abut. Regarding the position and function of the stopper 542, see... Figure 5 The orientation of the view is explained below. In one case, the stop block 542 is located on the side away from the contact surface of the main stop member 54, and in another case, the stop block 542 is located on the side closer to the contact surface of the main stop member 54. However, in both cases, the stop block 542 is set so that when the main stop member 54 and the secondary stop member 52 abut against each other and drive the transmission wheel 51 to rotate, the main stop member 54 is not pushed by the reaction force of the secondary stop member 52, and the main stop member 54 rotates further away from the secondary stop member 52, causing the two to separate, resulting in the failure of the seeding component 2 to start and causing missed seeding.

[0053] Furthermore, a movable limiting rod 57 is also connected to the transmission disc 53, and the main stop 54 can be moved to the side where the limiting rod 57 is away from the transmission wheel 51. Figure 5 As shown, the end of the main stop 54 furthest from its connection with the transmission disc 53 is the free end 541 of the main stop, and the end of the limiting rod 57 is the free end 571 of the limiting rod. When the sowing assembly 2 is closed, the main stop 54 can be rotated 90° counterclockwise. Figure 5 (View orientation), the free end 541 of the main stop member rotates to the left side of the free end 571 of the limit rod, and the main stop member 54 falls off and interferes with the auxiliary stop member 52 when the seeder is bumpy.

[0054] Preferably, the limiting rod 57 is connected to the elastic element 58, and the other end of the elastic element 58 is connected to the transmission disk 53. Through the setting of the elastic element 58, the limiting rod 57 can be disengaged from the transmission disk 53. When the free end 541 of the main stop member 54 rotates toward the limiting rod 57, it first disengages from the limiting rod 57, causing the free end 541 of the main stop member to rotate past the limiting rod 57, and then lowers the limiting rod 57, thereby causing the free end 541 of the main stop member to rotate to the left side of the free end 571 of the limiting rod.

[0055] The limiting rod 57 is connected to the connecting piece 56, and the other end of the connecting piece 56 is connected to the transmission disk 53. In this design, the connecting piece 56 is elastic. Of course, in some cases, the connecting piece 56 may not be elastic, in which case the connecting piece 56 and the transmission disk 53 are rotatably connected through the connecting shaft 55.

[0056] In another configuration, the connector 56 and the transmission disk 53 are rotatably connected via a connecting shaft 55. A torsion spring is connected to the connecting shaft 55, with one end of the torsion spring connected to the transmission disk 53 and the other end connected to the connector 56.

[0057] Regardless of how the limiting rod 57 is connected to the transmission disc 53, the purpose is to enable the limiting rod 57 to be lifted off and lowered again, thereby limiting the main stop 54.

[0058] The present invention provides a sowing start-stop mechanism that can control the start and stop of a certain sowing component 2. In the final stage of sowing, some sowing components can be shut off according to the condition of the remaining ground, so that the seeder can continue to sow on the remaining ground and realize fully mechanized sowing.

[0059] The terms "installation," "setup," "equipped with," and "connection" used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0060] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
