Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a tensioning mechanism for a seed box transmission component 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 sowing devices via a transmission mechanism. However, because the drive wheels are relatively far from the sowing device, the flexible transmission mechanism is prone to loosening. To prevent this loosening from affecting power transmission, a tensioning element is usually installed on one side of the transmission element. However, with existing tensioning elements, if the transmission element loosens again after tensioning, manual adjustment is usually required, thus affecting sowing efficiency. Utility Model Content

[0004] This utility model provides a tensioning mechanism for the transmission component of a seed box and a triangular seeder. The tensioning mechanism in this solution can adaptively tighten according to the looseness of the transmission component without manual adjustment, thereby improving the efficiency of seeding operations.

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

[0006] A tensioning mechanism for a seed box transmission component is provided for tensioning a transmission component, the transmission component being used to output power to the seeding assembly;

[0007] The tensioning mechanism includes a tensioning element, a tensioning connector, and a support assembly; the tensioning element is disposed on one side of the transmission component; both ends of the tensioning connector are connected to the support assembly, and the tensioning element is also connected to the tensioning connector;

[0008] The tensioning connector is elastic, and the elastic force applied by the tensioning connector to the tensioning element is opposite to the tensioning force applied by the transmission member to the tensioning element, and the tensioning element is movable under the action of the elastic force and the tensioning force.

[0009] As a further improvement, the support assembly includes a second support and a connecting frame connected together, with the other end of the second support connected to the main support.

[0010] As a further improvement, the tensioning connector includes a tensioning elastic element and a tensioning connecting rod connected together, with the tensioning element located at the connection between the tensioning elastic element and the tensioning connecting rod; the other end of the tensioning elastic element is connected to a second bracket, and the other end of the tensioning connecting rod is connected to a connecting frame.

[0011] As a further improvement, the tensioning connector includes a tensioning elastic element and a second elastic element connected together, with the tensioning element located at the connection between the tensioning elastic element and the second elastic element; the other end of the tensioning elastic element is connected to a second bracket, and the other end of the second elastic element is connected to a connecting frame.

[0012] As a further improvement, an elongated hole is provided at one end of the tensioning connecting rod that connects to the tensioning element, and the tensioning element is connected to the elongated hole and can move along the length of the elongated hole.

[0013] As a further improvement, the tensioning connecting rod is connected to the connecting frame via a rotating shaft, and the tensioning connecting rod can rotate around the rotating shaft.

[0014] As a further improvement, the tensioning element is a tensioning wheel.

[0015] As a further improvement, the tensioning wheel can rotate along the transmission member.

[0016] This utility model also provides a triangular seeder, including the tensioning mechanism of the seed box transmission component, and also includes a seeding component and a power wheel, wherein the seeding component and the power wheel are both connected to the main support.

[0017] The power wheel is connected to the main drive shaft, the main drive shaft is connected to the driven shaft, the driven shaft is connected to the transmission component, the transmission component is also connected to the first transmission wheel, and the first transmission wheel is connected to the second transmission wheel; when the second transmission wheel rotates, the sowing assembly performs sowing.

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] (1) The tensioning mechanism of the seed box transmission component of this utility model has a tensioning element on one side of the transmission component. The tensioning element is connected to an elastic tensioning connector. Under the combined action of the elastic force of the tensioning connector and the tensioning force of the transmission component, the tensioning element can move according to the tension of the transmission component. The tensioning element is always in the position of tensioning the transmission component, so that the tensioning element can adaptively perform real-time tensioning.

[0020] (2) In the tensioning mechanism of the seed box transmission component of this utility model, an elongated hole is opened at one end of the tensioning connecting rod connected to the tensioning element.

[0021] (3) The tensioning mechanism of the seed box transmission component of this utility model has a tensioning wheel as the tensioning element, and the tensioning wheel can rotate along the transmission component, which reduces the friction between the tensioning element and the transmission component and facilitates the movement of the tensioning element.

[0036] 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.

[0037] Combination 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.

[0038] The drive wheel 3 is connected to the main drive shaft 301, which in turn is connected to the driven shaft 302. The driven shaft 302 is connected to the transmission component 201, which is also connected to the first transmission wheel 206. The first transmission wheel 206 is connected to the second transmission wheel 209. During the seeding process, the drive wheel 3 rolls on the ground. As the drive wheel 3 rolls, power is transmitted sequentially through the main drive shaft 301, the driven shaft 302, the transmission component 201, the first transmission wheel 206, and the second transmission wheel 209, ultimately driving the second transmission wheel 209 to rotate. When the second transmission wheel 209 rotates, the seeding assembly 2 begins to sow.

[0039] Regarding transmission component 201, transmission component 201 is a flexible transmission component. Flexible transmission components are a common type of transmission component, characterized by their flexibility or adaptability, such as transmission belts or transmission chains. In this solution, transmission component 201 is used as an example of a transmission chain for explanation.

[0040] To further explain, the transmission connections between the drive wheel 3 and the main drive shaft 301, between the main drive shaft 301 and the driven drive shaft 302, and between the first drive wheel 206 and the second drive wheel 209 are all made through a transmission chain. Both the first drive wheel 206 and the second drive wheel 209 are gears. Additionally, when necessary, connecting gears are fitted onto both the main drive shaft 301 and the driven drive shaft 302 to engage with the transmission chain.

[0041] To enable simultaneous sowing and fertilization, achieving integrated sowing and fertilization operations, the seeder in this design can also be equipped with a fertilization component 1, mounted above the main support 4. The drive shaft of the fertilization component 1 is also driven by a power wheel 3, which is connected to the main drive shaft 301 via a transmission chain. When the power wheel 3 rotates, it simultaneously drives the drive shaft to rotate, thereby performing fertilization.

[0042] In the seeder of this design, the transmission path between the drive shaft 302 and the first drive wheel 206 is relatively long. After prolonged operation, the transmission component 201 may become loose, thus affecting the transmission efficiency of the seeder. Therefore, this design also provides a tensioning mechanism for the transmission component of the seeder box.

[0043] Combination Figure 2-5 As shown, this embodiment provides a tensioning mechanism for a seeding box transmission component, which is used to tension the transmission component 201, and the transmission component 201 is used to output power to the seeding assembly 2.

[0044] Specifically, the tensioning mechanism includes a tensioning element 204, a tensioning connector, and a support assembly. The tensioning element 204 is disposed on one side of the transmission member 201. Both ends of the tensioning connector are connected to the support assembly, and the tensioning element 204 is also connected to the tensioning connector. The tensioning connector is elastic, and the elastic force applied by the tensioning connector to the tensioning element 204 is opposite to the tensioning force exerted by the transmission member 201 on the tensioning element 204. The tensioning element 204 is movable under the action of the elastic force and the tensioning force.

[0045] In this design, the tensioning mechanism of the seed box transmission component has an elastic force applied to the tensioning element 204 by the tensioning connector, which is opposite to the tensioning force exerted on the tensioning element 204 by the transmission component 201. Under the action of the elastic force and the tensioning force, the tensioning element 204 is movable. When the transmission component 201 becomes loose after prolonged operation, its tension decreases, resulting in a decrease in tension force. At this time, the elastic force applied to the tensioning element 204 by the tensioning connector causes the tensioning element 204 to move in the tensioning direction, further increasing the tension force and thus tensioning the transmission component 201. During this process, when the tension force of the transmission component 201 decreases, the elastic tensioning connector adjusts the position of the tensioning element 204 in real time, ensuring that the tensioning element 204 is always in the position that tensions the transmission component 201. This allows the tensioning element 204 to adaptively tension, reducing the frequency of maintenance or replacement of the tensioning mechanism.

[0046] like Figure 3 As shown, the support assembly includes a second support 203 and a connecting frame 205 connected together, with the other end of the second support 203 connected to the main support 4. A first drive wheel 206 is also mounted on the connecting frame 205. A first support 202 is also provided. One end of both the first support 202 and the second support 203 is connected to the main support 4, and the other end is connected to the connecting frame 205. The seeding assembly 2 is mounted on the connecting frame 205.

[0047] like Figure 5 As shown, the main support 4, the first support 202, the second support 203, and the connecting frame 205 roughly form a quadrilateral structure. During the sowing process, due to uneven ground, the sowing assembly 2 will vibrate, leading to uneven sowing. To reduce the degree of vibration, a shock-absorbing elastic element 211 is also provided. One end of the shock-absorbing elastic element 211 is connected to the second support 203, and the other end is connected to the first support 202, reducing the vibration of the connecting frame 205, thereby further reducing the vibration of the sowing assembly 2. In a specific embodiment, the shock-absorbing elastic element 211 can be a spring, using the elastic force of the spring to balance the degree of vibration.

[0048] Combined Figure 5 As shown, as a further improvement, the tensioning connector includes a tensioning elastic element 207 and a tensioning connecting rod 212 connected together, with a tensioning element 204 located at the connection between the tensioning elastic element 207 and the tensioning connecting rod 212. The other end of the tensioning elastic element 207 is connected to the second bracket 203, and the other end of the tensioning connecting rod 212 is connected to the connecting frame 205.

[0049] In one configuration, the tensioning connecting rod 212 is connected to the connecting frame 205 via a rotating shaft 210, and the tensioning connecting rod 212 can rotate around the rotating shaft 210. For example... Figure 5In this design, the tensioning elastic element 207 is a spring with a hook at one end. A support rod 208 is connected to the second bracket 203, and the hook can be attached to the support rod 208 for quick connection. A detailed explanation of the tensioning process is provided: for example, the tension of the newly replaced transmission component 201 is at its maximum, at which point the tensioning elastic element 207 and the tensioning connecting rod 212 form a certain angle. After prolonged operation, as the transmission component 201 gradually loosens, the tension gradually decreases, the tensioning elastic element 207 pulls the tensioning element 204 to move, and the tensioning connecting rod 212 rotates clockwise. Figure 5 (From the center view direction), the tensioning element 204 tensions the transmission component 201 in real time. The tensioning element 204 continues to move until the tensioning elastic element 207 and the tensioning connecting rod 212 are aligned in a straight line. After this, the transmission component 201 can be replaced or the number of chain links reduced for maintenance.

[0050] In another configuration, one end of the tensioning connecting rod 212 connected to the tensioning element 204 has an elongated hole. The tensioning element 204 is connected to this elongated hole and can move along its length. In this configuration, under the action of the elastic force of the tensioning elastic member 207 on the tensioning element 204 and the tensioning force of the transmission member 201 on the tensioning element 204, the tensioning element 204 moves along the elongated hole, thereby tensioning the transmission member 201 in real time until the tensioning element 204 moves to the maximum length of the elongated hole. In this configuration, the tensioning connecting rod 212 can rotate around the rotating shaft 210 or be fixedly connected to the rotating shaft 210; however, when the tensioning connecting rod 212 rotates around the rotating shaft 210, the tensioning element 204 can have a larger movable stroke.

[0051] In other embodiments, the tensioning connector includes a tensioning elastic element 207 and a second elastic element connected together, with a tensioning element 204 located at the connection between the tensioning elastic element 207 and the second elastic element; one end of the tensioning elastic element 207 is connected to a second bracket 203, and the other end of the second elastic element is connected to a connecting frame 205. Both the tensioning elastic element 207 and the second elastic element are springs; for example, the tensioning elastic element 207 applies a pulling force to the tensioning element 204, and the second elastic element applies a pushing force to the tensioning element 204. Figure 5 (The setting of the tensioning element 204 is illustrated as an example.) The tensioning effect is improved under the action of dual elastic forces.

[0052] In a preferred embodiment, the tensioning element 204 is a tensioning wheel. Furthermore, the tensioning wheel can rotate along the transmission member 201, thereby reducing the friction between the tensioning element 204 and the transmission member 201 when the tensioning element 204 moves, thus facilitating the movement of the tensioning element 204.

[0053] The tensioning mechanism of the seed box transmission component provided by this utility model, through the combined action of the elastic force applied to the tensioning element 204 by the tensioning connector and the tensioning force of the tensioning element 204 on the transmission component 201, enables the tensioning element 204 to adaptively and in real time tension the transmission component 201, eliminating the need for frequent manual adjustment of tension and improving the efficiency of seeding operations.

[0054] 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.

[0055] 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.
