Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and specifically relates to a steering wheel walking mechanism applied to ridged planting land. Background Technology

[0002] Ridging refers to turning over soil at intervals of a specific width in the field to form raised ridges and low-lying furrows. Ridging is widely used for vegetables and root crops, and has significant advantages such as improving soil structure, enhancing drainage efficiency, and optimizing the crop growing environment. However, when using agricultural machinery or robots to operate between ridges, the chassis height of most equipment is limited because it is designed for flat ground. The raised ridges can then become obstacles and interfere with the equipment chassis. Utility Model Content

[0003] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a steering wheel walking mechanism for ridged planting land. By increasing the chassis ground clearance and optimizing walking stability, agricultural machinery can adapt to complex terrain between two ridges.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The drive assembly drives the drive wheel to rotate. Two pairs of support wheels are provided at the bottom of the mounting frame. The track is wound around the drive wheel and the two pairs of support wheels and is driven by the drive wheel.

[0006] To better realize this utility model, the above structure is further optimized by providing guide wheels on both the left and right sides of the mounting frame, with the guide wheels abutting against the inner walls of both sides of the track.

[0007] To better realize this utility model, the above structure is further optimized. The drive component includes a walking motor and a transmission, and the walking motor drives the drive wheel to rotate through the transmission.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] The steering wheel walking mechanism provided by this utility model for use in ridged planting land utilizes a mounting frame set on the outer side of the bottom of the frame in combination with the track to raise the height of the frame, thereby increasing the height of the chassis mounted above the frame.

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 implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Please refer to Figure 1 and Figure 2 This utility model provides a steering wheel walking mechanism for ridged planting land, including a frame 1, a drive assembly 2, and a track 3. The drive assembly 2 is mounted on the frame 1. A mounting frame 4 is provided on the outer bottom of the frame 1, and a drive wheel 5 is provided on the top of the mounting frame 4. The drive assembly 2 drives the drive wheel 5 to rotate. Two pairs of support wheels 6 are provided at the bottom of the mounting frame 4 to support the ground. The track 3 is wound around the drive wheel 5 and the two pairs of support wheels 6, and is driven by the drive wheel 5. By placing the drive wheel 5 on the top of the mounting frame 4, this application avoids the transmission mechanism being too low and colliding with the ridge. The two pairs of support wheels 6 at the bottom are connected to the drive wheel 5 at the top through the track 3, thereby raising the height of the frame 1 while ensuring the height of the chassis mounted above the frame 1. When walking on ridged planting land, it can avoid the chassis above the frame 1 colliding with the ridge. By increasing the ground clearance of the chassis and optimizing the walking stability, the agricultural machinery can adapt to the complex terrain between the ridges.

[0023] In addition, in order to improve the stability of the track 3 when it is moving, guide wheels 7 are provided on both the left and right sides of the mounting frame 4. The guide wheels 7 abut against the inner walls of both sides of the track 3 to ensure smooth transmission of the track 3.

[0024] In this embodiment, the drive assembly 2 includes a walking motor 201 and a transmission 202. The walking motor 201 drives the drive wheel 5 to rotate through the transmission 202, providing greater torque to the walking mechanism. The walking motor 201 is a servo motor with high control precision.

[0025] This application also designs a component for steering the walking mechanism. A connecting frame 8 is provided on the top of the frame 1, and the frame 1 is rotatably connected to the connecting frame 8 via a slewing bearing. A steering component 9 is provided between the connecting frame 8 and the frame 1, and the steering component 9 controls the steering of the frame 1. The steering component 9 includes a gear disk 901 mounted on the connecting frame 8, a drive gear 902 mounted on the frame 1, and a steering motor 903. The steering motor 903 drives the drive gear 902 to rotate, and the drive gear 902 meshes with the gear disk 901 for transmission. When the drive gear 902 rotates, the drive gear 902 continuously meshes with the gear disk 901. Since the gear disk 901 is mounted on the connecting frame 8 and cannot move, the drive gear 902 carries the frame 1 to rotate around the center of the gear disk 901, thereby realizing the steering of the frame 1 and the track 3 below it.

[0026] To improve steering accuracy, an angle gear 10 is also installed on the frame 1. The angle gear 10 meshes with the gear disk 901 for transmission. An angle sensor 11 is installed on the angle gear 10. The rotation angle of the angle gear 10 is obtained through the angle sensor 11 to obtain the steering angle of the frame 1. By cooperating with the steering motor 903, more precise steering control is achieved.

[0027] During operation, the mounting frame 4 above the frame 1 is connected to the chassis. Since the track 3 below the frame 1 is arranged differently from the traditional transverse track vehicle structure, the track 3 in this application is arranged vertically, and the power source and transmission mechanism are placed at the top, ensuring the height of the chassis mounted above the frame 1. When walking on the ridged planting field, the chassis above the frame 1 can avoid collision with the ridge.

[0028] 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 variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
