Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of agricultural machinery equipment, and provides a walking self-adaptive structure for agricultural machinery, which is high in land adaptability, low in cost, safe and reliable, and simple in maintenance. BACKGROUND

[0002] The existing agricultural machinery power walking structure is rigidly connected with the large frame of the rotary cultivator, such as the rotary cultivator scheme described in Chinese patents CN117296484A and CN220674294U. The walking structure of the existing harvester is also basically the scheme described in the foregoing rotary cultivator.

[0003] When the above-mentioned structure of agricultural machinery is used, when the land is uneven, the walking wheel drives the rotary cultivator to fluctuate, thereby driving the rotary cultivator to fluctuate, resulting in poor rotary cultivation quality; and the walking structure is high in manufacturing cost, complex in structure, and difficult to maintain in later period. SUMMARY

[0004] Therefore, the purpose of the application is to provide a walking self-adaptive structure for agricultural machinery, which is high in land adaptivity, low in cost, safe and reliable, and simple in maintenance.

[0005] To achieve the above-mentioned purpose, the application provides a walking self-adaptive structure for agricultural machinery, which comprises a shell, a shell side cover fixedly connected with the shell, a walking shaft rotatably connected with the shell, a driven gear provided on the walking shaft, a driving gear provided on a power input shaft and engaged with the driven gear, and a short shaft fixedly connected with the shell and symmetrically arranged on both sides of the shell with the power input shaft. The short shaft and the power input shaft are respectively located in the mounting holes of the rotary cultivator large frame on both sides of the shell. When used, the walking shaft is provided with walking wheels or a track.

[0006] To ensure the rotation of the walking shaft and the power input shaft after installation, in the above-mentioned scheme, further, the walking shaft is connected with the shell and the shell side cover through bearings a and b respectively, and the power input shaft is connected with the shell through a bearing c.

[0007] To make the transmission structure simple and stable in power transmission, and easy to maintain in later period, in the above-mentioned scheme, further, the axis of the walking shaft and the axis of the power input shaft are perpendicular to each other, and the driving gear and the driven gear are both umbrella gears.

[0008] To facilitate convenient maintenance in later period, in the above-mentioned scheme, further, the shell and the shell side cover are fixedly connected as a whole through bolts.

[0009] The beneficial effects of the present application are: when the rotary cultivator cultivates on uneven land, the walking device self-adapts to the uneven land conditions, and the walking structure is movably connected with the rotary cultivator frame, so that the rotary cultivator always maintains stable cultivation of the land. That is, when the left and right walking wheels travel on the high-low concave-convex soil surface, the walking wheels bounce up and down, and the rotary cultivator frame and the rotary cultivation part are movably connected with the walking shell in a longitudinal symmetrical shaft, so that the left and right walking wheels always rotate around the longitudinal symmetry of the shell, and the rotary cultivator frame and the rotary cultivator always maintain stability, which effectively ensures the rotary cultivation quality. In summary, the device described in the present application has the advantages of simple structure, low cost, safety and reliability, simple maintenance, and strong land adaptability.

[0014] like Figs. 1-2 As shown, the adaptive walking structure for agricultural machinery of the present invention includes a housing 2, a housing side cover 3 fixedly integrated with the housing 2, a walking shaft 6 rotatably connected to the housing 2, a driven gear 5 provided on the walking shaft 6, a driving gear 13 meshing with the driven gear 5 and provided on a power input shaft 4, the power input shaft 4 being rotatably connected to the housing 2, and a short shaft 7 fixed on the housing 2, the short shaft 7 being symmetrically arranged on both sides of the housing 2 with the power input shaft 4; The short shaft 7 and the power input shaft 4 are respectively located in the mounting holes 12 of the rotary tiller frame 1 on both sides of the housing 2; In use, the traveling shaft 6 is equipped with traveling wheels or tracks. In this embodiment, the gears and shafts are connected by conventional splines, and the short shaft 7 and the power input shaft 4 are intermittently fitted with the mounting hole 12. In this scheme, the agricultural machinery refers to a rotary tiller or a harvester. The rotary tiller blades of the rotary tiller or the agricultural machinery frame of the harvester are mounted on the rotary tiller frame 1. Taking a rotary tiller as an example, in this embodiment, external power is transmitted to the driving gear 13 through the spline on the power input shaft 4. The driving gear 13 transmits power to the driven gear 5 through its teeth. The driven gear 5 transmits power to the traveling shaft 6 through the spline in its gear center hole. The traveling shaft 6 drives the traveling wheels or tracks mounted on the left and right to realize the forward or backward movement of the rotary tiller. When the agricultural machinery is a harvester, its power transmission is the same as that of a rotary tiller.

[0017] All components in the above embodiments are commercially available products. The description of other functionalities of the agricultural machinery involved in this embodiment employs conventional technical means.

[0018] The working process of the structure described in the above embodiments is as follows: in actual rotary tillage, when the rotary tiller encounters a bump on the left side, the left side of the walking self-adapting device is lifted, the walking self-adapting device is tilted clockwise around the power input shaft 4 and the short shaft 7 of the driving gear 13, and the rotary tiller tool on the rotary tiller frame 1 remains horizontal. When a pit is encountered, the left side of the walking self-adapting device is lowered, the walking self-adapting device is tilted counterclockwise around the power input shaft 4 and the short shaft 7 of the driving gear 13, and the rotary tiller tool on the rotary tiller frame 1 remains horizontal.

[0019] In actual rotary tillage, when the right side encounters a bump, the right side of the walking self-adapting device is lifted, the walking self-adapting device is tilted counterclockwise around the power input shaft 4 and the short shaft 7 of the driving gear 13, and the rotary tiller tool on the rotary tiller frame 1 remains horizontal. When a pit is encountered, the right side of the walking self-adapting device is lowered, the walking self-adapting device is tilted clockwise around the power input shaft 4 and the short shaft 7 of the driving gear 13, and the rotary tiller tool on the rotary tiller frame 1 remains horizontal.

[0020] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions, and all of them should be covered in the scope of the claims of the present application.
