Description

A laser cotton topping machine based on a gimbal structure Technical Field

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

[0002] Topping cotton is an agronomic technique that involves manually or mechanically removing the apical meristem to break apical dominance and promote lateral branching. This technique directs nutrients towards reproductive growth, thereby increasing the number of bolls and cotton yield.

[0003] Currently, laser topping machines are available to replace manual topping of cotton. However, the unevenness of the cotton field road surface can cause changes in the vehicle's posture, which in turn causes changes in the position of the laser head 6 at the end. As a result, the laser spot cannot fall on the target, which cannot guarantee the precise and stable operation of the topping machine and affects the topping efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a laser cotton topping machine based on a gimbal 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 laser cotton topping machine based on a gimbal structure includes a support platform. Steering columns are provided at the four corners of the bottom of the support platform. A steering connecting rod is fixedly connected to the side wall of each steering column. A damping spring shock absorber is provided at the end of each steering connecting rod. An L-shaped frame is provided at the bottom of the damping spring shock absorber. Wheels are mounted on the L-shaped frame. A horizontal adjustment mechanism is provided on one side of the upper surface of the support platform. An end laser head is provided in the middle of the horizontal adjustment mechanism. A laser generator is provided on the other side of the upper surface of the support platform. A tilt sensor is provided in the middle of the front side of the upper surface of the support platform.

[0006] Preferably, the bottom of the support platform is provided with a connecting frame on the outside of each steering column, and a drive motor for driving the steering column to rotate is installed at the bottom of each connecting frame.

[0007] Preferably, battery racks are provided at the bottom of both ends of the support platform, and each battery rack contains a battery.

[0008] Preferably, the horizontal adjustment mechanism includes a Y-axis rotating gimbal motor, a bracket, and a frame. One end of the frame is rotatably connected to the bracket via a rotating shaft, and the other end of the frame is connected to the shaft of the Y-axis rotating gimbal motor. The end laser head is vertically disposed in the middle part of the frame, and one side of the end laser head is rotatably connected to one side of the frame via a rotating shaft. An X-axis rotating gimbal motor is installed on the other side of the frame, and the shaft of the X-axis rotating gimbal motor is connected to the side wall of the end laser head.

[0009] Preferably, the bottom of the Y-axis rotating gimbal motor is provided with a motor frame, and the bottom of both the motor frame and the bracket are fixedly connected to the upper surface of the support platform.

[0010] Preferably, the surface of the support platform is provided with a rectangular opening, the horizontal adjustment mechanism is located above the rectangular opening, and the bottom of the end laser head extends to below the rectangular opening.

[0011] Preferably, the laser generator is connected to the end laser head via an optical fiber.

[0012] The laser cotton topping machine based on a gimbal structure of this utility model has the following advantages:

[0013] 1. This utility model uses a tilt sensor to detect changes in the vehicle's posture in real time. When the vehicle tilts, the gimbal motors in two directions control the end laser head to make corresponding adjustments to counteract the effect of the vehicle tilt on the laser operation, thereby maintaining the stability of the laser beam and ensuring that the laser spot always falls on the target. This enables the top-attacking machine to operate accurately and stably during travel, improving the top-attacking efficiency.

[0014] 2. This utility model, by installing an independently driven wheel motor on each wheel and setting each of the four wheels to have an independent steering linkage, makes the topping machine more flexible in complex cotton field environments, enabling precise adjustment of the driving direction. When changing rows, it can reduce the turning radius and improve passability. When the topping machine is traveling in the cotton field, the independent damping spring shock absorbers of each wheel can reduce the interference of uneven road surface on the topping operation.
