Technical Field
[0001] This utility model relates to the field of lawn planting and mowing technology, and in particular to a high-efficiency lawn planting and mowing robot. Background Technology
[0002] In recent years, with the rapid development of my country's economy, the traditional method of manually dragging lawnmowers for lawn mowing has become increasingly costly. Furthermore, the quality of lawn mowing and the thickness of vegetation lack long-term, effective management. Therefore, autonomous lawn mowing robots, which replace operators and lawnmowers, have emerged. In the field of modern garden maintenance and outdoor lawn management, lawn mowing robots are being used more and more widely, aiming to improve the efficiency and accuracy of lawn mowing and reduce labor costs.
[0003] Existing lawn mowing robots, due to the limitation that the blades cannot be too large, can only trim the central blade area when mowing the lawn. The remaining areas are only trimmed when the robot returns to its starting position. This not only increases the number of times the robot needs to trim but also increases its working time, thus reducing the efficiency of the lawn mowing robot. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a highly efficient lawn planting and mowing robot, which aims to improve the problem of the small mowing range of mowing robots when mowing lawns.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency lawn planting and mowing robot, comprising a chassis support, a drive motor fixedly connected to the top of the chassis support, a first bevel gear fixedly connected to the output end of the drive motor, a second bevel gear meshing with the tooth end of the first bevel gear, a transmission frame fixedly connected to the bottom end of the second bevel gear, a transmission gear rotatably connected to the outer wall of the transmission frame, an internal gear ring meshing with the tooth end of the transmission gear, a connecting shaft fixedly connected to the bottom end of the transmission gear, a mowing blade fixedly connected to the bottom end of the connecting shaft, and a swing assembly provided on the inner wall of the chassis support.
[0006] Preferably, the oscillating assembly includes a rotating disk, a rotating gear is slidably connected to the outer wall of the rotating disk, a movable frame is engaged with the tooth ends of the rotating gear, two connecting frames are fixedly connected to the right side of the movable frame, and a rake claw is fixedly connected to the far side of the two connecting frames.

[0011] Preferably, the rotating gear is rotatably connected to the outer wall of the chassis support, and the movable frame is slidably connected to the outer wall of the chassis support.
[0012] Preferably, one of the synchronous pulleys is rotatably connected to the outer wall of the chassis support.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, a planetary gear transmission mechanism is formed by a transmission frame, a transmission gear, and an internal gear ring. When the drive motor drives the first bevel gear and the second bevel gear to rotate, the transmission frame drives the transmission gear to rotate inside the internal gear ring through the second bevel gear.

Detailed Implementation
[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figure 1 - Figure 3 An embodiment of this utility model provides: a high-efficiency lawn planting and mowing robot, including a chassis support 1, a drive motor 3 fixedly connected to the top of the chassis support 1, a first bevel gear 4 fixedly connected to the output end of the drive motor 3, a second bevel gear 5 meshing with the tooth end of the first bevel gear 4, a transmission frame 6 fixedly connected to the bottom end of the second bevel gear 5, a transmission gear 7 rotatably connected to the outer wall of the transmission frame 6, an internal gear ring 10 meshing with the tooth end of the transmission gear 7, a connecting shaft 8 fixedly connected to the bottom end of the transmission gear 7, a mowing blade 9 fixedly connected to the bottom end of the connecting shaft 8, and a swing assembly provided on the inner wall of the chassis support 1.
[0024] Specifically, the drive motor 3 drives the first bevel gear 4 to rotate, which in turn drives the second bevel gear 5 to rotate the transmission frame 6. The transmission gear 7, through meshing with the internal gear ring 10, can drive the connecting shaft 8 and the trimming blade 9 to rotate. The trimming blade 9 rotates along with the transmission gear 7, thereby increasing the trimming range.
[0025] Reference Figure 2 - Figure 4 The swing assembly includes a rotating disk 13, a rotating gear 14 slidably connected to the outer wall of the rotating disk 13, a movable frame 15 meshing with the tooth ends of the rotating gear 14, two connecting frames 16 fixedly connected to the right side of the movable frame 15, and a rake claw 17 fixedly connected to the far side of the two connecting frames 16; a synchronous wheel 11 fixedly connected to the outer wall of the rotating disk 13, and a synchronous belt 12 meshing with the tooth ends of the synchronous wheel 11; one of the synchronous wheels 11 is fixedly connected to the outer wall of the transmission frame 6, and the rotating disk 13 is rotatably connected to the inner wall of the chassis support 1.
[0026] Specifically, two synchronous wheels 11 are fixed to the outer walls of the transmission frame 6 and the rotating disk 13, respectively, and mesh with the synchronous belt 12. This allows the transmission frame 6 to drive the rotating disk 13 to rotate via the synchronous wheels 11 and the synchronous belt 12. As the rotating disk 13 rotates, the slider at the top of the rotating disk 13 drives the rotating gear 14 to swing. The right end of the rotating gear 14 meshes with the left end of the moving frame 15, allowing the moving frame 15 to drive the rake claw 17 to move back and forth via the connecting frame 16. During the movement, the rake claw 17 sweeps the scattered stems and leaves on the lawn towards the center, causing the stems and leaves to pile up in the middle of the mowing path, thus facilitating the collection and processing of the stems and leaves.
[0027] Reference Figure 1 and Figure 2 The outer wall of the chassis bracket 1 is fixedly connected to the outer shell 2, the inner wall of the chassis bracket 1 is rotatably connected to the drive wheel 18, and the inner wall of the chassis bracket 1 is rotatably connected to the driven wheel 19.
[0028] Specifically, the outer shell 2 is mounted on the chassis support 1, which can protect the internal structure of the robot from damage caused by external factors. At the same time, the drive wheel 18 can drive the chassis support 1 and the driven wheel 19 to move and turn the robot, so as to facilitate the robot to perform lawn mowing work.
[0029] Reference Figure 3 The second bevel gear 5 is rotatably connected to the outer wall of the chassis support 1, the transmission frame 6 is rotatably connected to the inner wall of the chassis support 1, and the internal gear ring 10 is fixedly connected to the outer wall of the chassis support 1.
[0030] Specifically, the bottom end of the second bevel gear 5 rotates on the outer wall of the top end of the chassis support 1, and the outer wall of the top end of the transmission frame 6 is rotatably connected to the inner wall of the top end of the chassis support 1. This allows the transmission gear 7 to rotate stably through the transmission frame 6, enabling the transmission gear 7 to drive the connecting shaft 8 and the trimming blade 9 to rotate through the internal gear ring 10. This not only increases the rotational speed of the trimming blade 9, but also increases the trimming range of the trimming blade 9.
[0031] Reference Figure 1 and Figure 4 The rotating gear 14 is rotatably connected to the outer wall of the chassis support 1, and the movable frame 15 is slidably connected to the outer wall of the chassis support 1; one of the synchronous pulleys 11 is rotatably connected to the outer wall of the chassis support 1.
[0032] Specifically, through the synchronous pulley 11 and synchronous belt 12, the rotating disk 13 can drive the rotating gear frame 14 to move through the transmission frame 6. The middle part of the rotating gear frame 14 is rotatably connected to the sliding column on the right side of the chassis support 1, so that the rotating gear frame 14 can rock back and forth through the rotation of the rotating disk 13, thereby driving the moving frame 15 to move back and forth on the right side of the chassis support 1, so that the rake claw 17 can sweep the stems and leaves towards the middle of the pruning channel, achieving the effect of facilitating the collection and processing of stems and leaves.
[0033] Working principle: When the trimming robot is started, the first bevel gear 4 drives the second bevel gear 5 to rotate through the drive motor 3. The second bevel gear 5 drives the transmission frame 6 to rotate on the inner wall of the chassis support 1. The transmission gear 7 rotates at the bottom of the transmission frame 6 and rotates with the transmission frame 6 in the internal gear ring 10. By meshing with the tooth end of the internal gear ring 10, it can drive the connecting shaft 8 and the trimming blade 9 to rotate. During the process of trimming the lawn, the connecting shaft 8 and the trimming blade 9 will rotate around the internal gear ring 10 with the transmission gear 7, thereby increasing the trimming range.
[0034] While the transmission frame 6 rotates, the left synchronous wheel 11 is fixedly connected to the transmission frame 6. Through meshing with the synchronous belt 12, it can drive the right synchronous wheel 11 to rotate, thereby driving the rotating disk 13 to rotate. The inner wall of the left side of the rotating gear frame 14 contacts the sliding column at the top of the rotating disk 13, the middle part is rotatably connected to the chassis support 1, and the tooth end on the right side meshes with the second bevel gear 5. When the rotating disk 13 rotates, it drives the rotating gear frame 14, causing its right side to drive the moving frame 15, connecting frame 16, and rake claw 17 to move back and forth, so that the rake claw 17 can sweep the stems and leaves, achieving the effect of facilitating the collection and processing of stems and leaves.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
