Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, and in particular relates to a cotton topping machine chassis based on a six-wheel structure. Background Technology

[0002] A cotton laser topping machine is a mechanical device that uses laser technology to toggle cotton plants, aiming to improve the efficiency and accuracy of topping while reducing damage to the cotton. Topping is a crucial step in cotton cultivation; by removing the top of the cotton plant, it inhibits vegetative growth, promotes boll formation, and thus increases cotton yield and quality.

[0003] Currently, the uneven road surface in cotton fields makes it difficult for the laser topping machine to pass through, and the drive wheels are prone to slipping, which affects the topping effect on the cotton. Utility Model Content

[0004] The purpose of this utility model is to provide a cotton topping machine chassis based on a six-wheel structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A cotton topping machine chassis based on a six-wheel structure includes a support platform. The support platform includes an outer frame, a middle frame, and an inner frame. The middle frame is located inside the outer frame, and the inner frame is located inside the middle frame. A fixing rod is provided on one side of the inner wall of the outer frame, located on the middle frame. A support plate is provided between the fixing rod and the inner wall of the outer frame. An x-axis drive mechanism for driving the middle frame to rotate along the x-axis direction is provided on the support plate. The inner frame has a y-axis drive mechanism at both ends for driving the inner frame to rotate along the y-axis. The upper surface of the middle frame away from the x-axis drive mechanism is connected to the outer frame through an auxiliary rotation structure. The bottom of one end of the outer frame has a rear wheel set and the bottom of the other end has a front wheel set. The front wheel set includes a connecting axle. Both ends of the connecting axle are fixedly connected to a fixing rod by fixing parts. Both ends of the connecting axle are rotatably connected to a V-frame through bearings. Both ends of the V-frame are equipped with movable wheels.

[0006] Preferably, the upper surface of the internal frame is provided with four leak repair lasers and two main execution lasers.

[0007] Preferably, two batteries are mounted on the upper surface of the tray.

[0008] Preferably, the auxiliary rotating structure includes two connecting seats, which are respectively mounted on the upper surfaces of the outer frame and the middle frame, and a rotating shaft is rotatably connected between the two connecting seats via a bearing.

[0009] Preferably, the x-axis drive mechanism includes a stepper motor and two bearing seats. The two bearing seats are respectively mounted on the upper surface of the fixed rod and the middle frame. A rotating shaft is rotatably connected between the two bearing seats through bearings. The shaft of the stepper motor is connected to the rotating shaft. The rotating shaft and the rotating shaft of the auxiliary rotating structure are both fixedly connected to the bottom of the middle frame through a U-shaped frame. The structure of the y-axis drive mechanism is the same as that of the x-axis drive mechanism.

[0010] Preferably, the stepper motor of the x-axis drive mechanism is fixedly connected to the upper surface of the tray, and the stepper motor of the y-axis drive mechanism is fixedly connected to the upper surface of the internal frame.

[0011] Preferably, the rear wheel assembly includes a support frame, a wheel is mounted on one side of the support frame via a hub motor, a mounting frame is provided above the support frame, a steering motor is mounted inside the mounting frame, the shaft of the steering motor is fixedly connected to the upper surface of the support frame via a planetary reducer, and the structure of the movable wheel is the same as that of the front wheel assembly.

[0012] The cotton topping machine chassis based on a six-wheel structure of this utility model has the following advantages:

[0013] This invention utilizes two V-shaped frames on the front wheel assembly to rotate around a connecting shaft, ensuring that two moving wheels on each side are always in contact with the ground and have a certain driving capability during movement. Simultaneously, all six wheels of the chassis are driven by hub motors, each equipped with an identical steering mechanism to ensure the chassis's movement and steering. This keeps the wheels in contact with the ground, guaranteeing stability and maneuverability. It also provides additional stability and anti-rollover functionality when the vehicle traverses uneven surfaces or performs specific operations. Since uneven ground during driving may prevent the laser from effectively illuminating the top of the cotton bud, when the chassis tilts along the y-axis, the two stepper motors on the internal frame are adjusted to ensure the laser effectively illuminates the cotton bud. Similarly, when the chassis tilts along the x-axis, the stepper motors on the external frame are adjusted accordingly, ensuring the support platform remains horizontal. This ensures the actuator operates in a horizontal state, enabling real-time adjustment and stable control of the support platform. Attached Figure Description

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a cotton topping machine chassis based on a six-wheel structure.

[0029] like Figure 1-7As shown, this utility model discloses a cotton topping machine chassis based on a six-wheel structure, including a support platform 1. The support platform 1 includes an outer frame 9, a middle frame 10, and an inner frame 4. The middle frame 10 is located inside the outer frame 9, and the inner frame 4 is located inside the middle frame 10. Four leak-filling lasers 6 and two execution lasers 7 are respectively arranged on the upper surface of the inner frame 4. A fixing rod 13 is arranged on the inner wall of the outer frame 9 on one side of the middle frame 10. A support plate 5 is arranged between the fixing rod 13 and the inner wall of the outer frame 9. Two batteries 8 are installed on the upper surface of the support plate 5. The support plate 5 is provided with a mechanism for driving the middle frame 10 along the x-axis direction. The rotating x-axis drive mechanism 11 has two y-axis drive mechanisms 12 at both ends of the inner frame 4 for driving the inner frame 4 to rotate along the y-axis. The upper surface of the middle frame 10 away from the x-axis drive mechanism 11 is connected to the outer frame 9 through an auxiliary rotation structure. The auxiliary rotation structure includes two connecting seats, which are respectively installed on the upper surfaces of the outer frame 9 and the middle frame 10. A rotating shaft is rotatably connected between the two connecting seats through a bearing. When the x-axis drive mechanism 11 drives the middle frame 10 to rotate along the x-axis, the middle frame 10 can rotate stably under the action of the auxiliary rotation structure.

[0030] The x-axis drive mechanism 11 includes a stepper motor 14 and two bearing seats 15. The two bearing seats 15 are respectively mounted on the upper surface of the fixed rod 13 and the middle frame 10. A rotating shaft 16 is rotatably connected between the two bearing seats 15 via bearings. The shaft of the stepper motor 14 is connected to the rotating shaft 16. The rotating shaft 16 and the rotating shaft of the auxiliary rotating structure are both fixedly connected to the bottom of the middle frame 10 via a U-shaped frame 27. The U-shaped frame 27 ensures that no relative rotation occurs. The structure of the y-axis drive mechanism 12 is the same as that of the x-axis drive mechanism 11. By starting the stepper motor 14, the rotating shaft 16 can be rotated, so that the middle frame 10 or the inner frame 4 can rotate around the axis of the rotating shaft 16 connected to it. The stepper motor 14 of the x-axis drive mechanism 11 is fixedly connected to the upper surface of the support plate 5, and the stepper motor 14 of the y-axis drive mechanism 12 is fixedly connected to the upper surface of the inner frame 4.

[0031] The outer frame 9 has a rear wheel assembly 2 at one end and a front wheel assembly 3 at the other end. The front wheel assembly 3 includes a connecting axle 17, both ends of which are fixedly connected to a fixing rod 13 via fasteners 20. Both ends of the connecting axle 17 are rotatably connected to a V-frame 18 via bearings, and both ends of the V-frame 18 are fitted with movable wheels 19. The rear wheel assembly 2 includes a support frame 22, one side of which is fitted with a wheel 21 via a hub motor 26. A mounting frame 23 is located above the support frame 22, and a steering motor 24 is mounted inside the mounting frame 23. The shaft of the steering motor 24 is fixedly connected to the upper surface of the support frame 22 via a planetary reducer 25. The movable wheels 19 have the same structure as the rear wheel assembly 2. By activating the hub motor 26, the wheel 21 can roll; by activating the steering motor 24, the wheel 21 can be steered.

[0032] The working principle of this six-wheeled cotton topping machine chassis is as follows: The two V-shaped frames 18 of the front wheel assembly 3 can rotate around the connecting shaft 17 to a certain extent. During travel, it ensures that two moving wheels 19 on each side are in contact with the ground and have a certain driving capability. Simultaneously, all six wheels 21 of the chassis are driven by hub motors 26, and each wheel is equipped with the same steering mechanism to ensure the chassis's movement and steering. Six solid-state lasers are installed on the internal frame 4, with the central laser being the main actuator and the two side lasers serving as fillers. Because uneven ground during travel may prevent the lasers from effectively illuminating the top of the cotton bud, when the chassis tilts in the y-axis direction, the two stepper motors 14 of the internal frame 4 are adjusted to ensure the lasers effectively illuminate the cotton bud. Similarly, when the chassis tilts in the x-axis direction, the stepper motors 14 of the external frame are adjusted accordingly.

[0033] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
