Description

Technical Field

[0001] This utility model relates to a transmission structure, specifically to a mechanical in-situ steering tracked rotary tiller transmission structure. Background Technology

[0002] Traditional tracked rotary tillers typically use hydraulic or other steering mechanisms for steering. These mechanisms are complex in structure and have a large turning radius, making them difficult to operate flexibly, especially in narrow plots and complex terrain. They are inefficient and difficult to operate, particularly when turning on the spot.

[0003] During turning or moving forward, due to the lack of guidance on the movement trajectory of the track components, tracked rotary tillers may experience problems such as track deviation and jamming, affecting the stability and smoothness of their turning, and in severe cases, even causing the equipment to malfunction. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mechanical in-situ steering tracked rotary tiller transmission structure to solve the problems existing in the background art.

[0005] The transmission structure of this mechanical in-situ steering tracked rotary tiller is achieved through the following technical solution, including a mounting plate and track components;

[0006] The track assembly is located on both sides below the mounting plate, and the track assembly is connected to the mounting plate through a rotating structure; the rotary tiller body is mounted on the top of the mounting plate, and the land is cultivated by the rotary tiller body.

[0007] As a preferred technical solution, the rotating structure includes a rotary motor and a fixed plate;

[0008] The rotary motor is fixed above the mounting plate by a mounting base, and the output shaft of the rotary motor passes through the mounting plate;

[0009] The fixing plate is disposed on one side of the track assembly and is connected to the drive shaft of the track assembly; a connecting plate is provided at the upper end of the mounting plate, and the output shaft of the rotary motor is connected to the connecting plate; the track assembly is driven to rotate by the rotation of the rotary motor.

[0010] As a preferred technical solution, guide rods are provided on both sides of the connecting plate, and guide grooves corresponding to the track assembly are provided on the mounting plate;

[0011] The guide rod is placed in the guide groove. When the rotary motor drives the track assembly to rotate, the guide rod slides in the guide groove.

[0012] As a preferred technical solution, a limit block is provided on the guide rod to limit the upper end of the guide rod to the mounting plate.

[0013] As a preferred technical solution, the track assembly is driven by a bidirectional drive motor for forward and reverse rotation of the track assembly.

[0014] As a preferred technical solution, the track body of the track assembly is provided with V-shaped patterns, which provide an anti-slip effect.

[0015] The beneficial effects of this utility model are:

[0016] This invention, by employing a rotary motor and connecting plate, enables the tracked rotary tiller to turn in place under the action of the track assembly. Compared with traditional designs, this invention improves the operational flexibility of the rotary tiller and is particularly suitable for operations in narrow plots and complex terrains.

[0017] This invention features a guide rod and a corresponding guide groove. The guide rod slides within the guide groove, which guides the movement trajectory of the track assembly, ensuring the stability and smoothness of the rotary tiller during turning and preventing operational difficulties caused by track misalignment or jamming.

[0024] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0025] like Figures 1-3 As shown, the present invention discloses a mechanical in-situ steering tracked rotary tiller transmission structure, including a mounting plate 1 and a track assembly 2.

[0026] The track assembly 2 is located on both sides below the mounting plate 1, and the track assembly 2 is connected to the mounting plate 1 through a rotating structure; the rotary tiller body is installed on the top of the mounting plate 1, and the land is cultivated by the rotary tiller body.

[0027] The rotating structure includes a rotary motor 3 and a fixed plate 4;

[0028] The rotary motor 3 is fixed above the mounting plate 1 by the mounting base 6, and the output shaft of the rotary motor 3 passes through the mounting plate 1;

[0029] The fixing plate 4 is disposed on one side of the track assembly 2 and is connected to the drive shaft 10 of the track assembly 2; the upper end of the mounting plate 1 extends inward and is provided with a connecting plate 5, and the output shaft of the rotary motor 3 is connected to the connecting plate 5; the track assembly 2 is driven to rotate by the rotation of the rotary motor 3.

[0030] In order to serve as a guide, in this embodiment, guide rods 7 are provided on both sides of the connecting plate 5, and guide grooves 8 corresponding to the track assembly 2 are provided on the mounting plate 1.

[0031] The guide rod 7 is placed in the guide groove 8. When the rotary motor 3 drives the track assembly 2 to rotate, the guide rod 7 slides in the guide groove 8.

[0032] In order to achieve smooth steering, in this embodiment, a limiting block 9 is provided on the guide rod 7, and the upper end of the guide rod 7 is limited on the mounting plate 1 by the limiting block 9.

[0033] To facilitate forward movement and turning, in this embodiment, the track assembly 2 is driven by a bidirectional drive motor for forward and reverse rotation of the track assembly 2.

[0034] In order to achieve the anti-slip effect, in this embodiment, the track body 11 of the track assembly 2 is provided with V-shaped texture 12, which achieves the anti-slip effect.

[0035] The rotary motor is fixed above the mounting plate by a mounting bracket, and its output shaft passes through the mounting plate and connects to the connecting plate. When the rotary motor starts, the rotational motion of its output shaft is transmitted to the connecting plate, which in turn drives the drive shaft of the track assembly to rotate through the fixed plate, causing the track assembly to move.

[0036] The track assembly of this invention is driven by a bidirectional drive motor, which supports the forward and reverse rotation functions of the track assembly, allowing the track to move forward or backward to meet different work requirements.

[0037] When a turn is required, the bidirectional drive motors of the left and right track assemblies work in opposite directions; one track rotates forward while the other rotates backward, achieving a turn in place through relative motion; the power provided by the rotary motor is transmitted to the track assembly through the connecting plate and the fixing plate, making the turning operation smoother and more precise; this linkage design solves the problems of large turning radius and poor flexibility of traditional tracked rotary tillers, and is particularly suitable for the operation needs of narrow plots and complex terrain.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
