[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Existing tracked chassis 1, such as Figure 1 As shown, the chassis 1 includes a chassis motor 11, tracks 12, drive wheels 14, and guide wheels 13. These are existing technologies with their own structures and principles, which will not be elaborated here. Agricultural equipment such as harvesting, tilling, and spraying can be installed on this chassis 1 to carry out corresponding agricultural operations, and it is especially suitable for agricultural operations in mountainous and hilly areas.

[0016] The tracked chassis provided in this embodiment adds a set of cleaning brush assemblies to each side of the existing chassis 1 for cleaning operations corresponding to the side tracks, such as... Figure 2 As shown. The sweeping brush assembly includes a mounting bracket 4, a brush platform 3, a sweeping brush 5, a brush platform motor 6, a pressure sensor 2, a microcontroller, etc.

[0017] A mounting frame 4 is fixed to the side of the chassis 1 corresponding to the track 12. The brush platform 3 is mounted on the mounting frame 4 in a linearly lifting manner. Several cleaning brushes 5 are installed side by side on the brush platform 3 at equal intervals. The brush heads of the cleaning brushes 5 are located below the brush platform 3 and correspond to the upper track 121 (e.g., ...). Figure 2As shown, the upper track referred to in this article is the track section located above the guide wheel and drive wheel. As the track rotates, the travel surfaces of each track with attached mud will successively change position to the upper position, forming the aforementioned upper track, thereby completing the cleaning of the travel surfaces around the entire circumference of the track. Above the upper surface, each sweeping brush 5 is rotatably connected and assembled with the brush platform 3, and a transmission wheel 7 is fixed at the upper end of each sweeping brush 5. The brush platform motor 6 is fixed on the brush platform 3, and the output end of the brush platform motor 6 is connected to each transmission wheel 7 in sequence through a transmission belt. Starting the brush platform motor 6 can drive each transmission wheel 7 to rotate, thereby driving each sweeping brush 5 to rotate.

[0018] Of course, in order to improve the transmission effect, the transmission belt is connected to each transmission wheel in an S-shape. In addition, a tension wheel 9 is installed on the outer side of each transmission wheel on both sides of the brush table 3. The transmission belt passes around the tension wheel 9 and is connected to the transmission wheel 7.

[0019] The brush table 3 and the mounting frame 4 can be linearly and reciprocally slidably connected. An electric telescopic drive device, such as an electric telescopic rod 10, is fixed on the mounting frame 4 to drive the brush table 3 to rise and fall. In order to improve the stability of the brush table 3 rising and falling, a guide rod 8 is installed on the mounting frame 4 to guide the brush table 3.

[0020] In this embodiment, the cleaning brush 5 is not in constant contact with the upper track. Only after detecting that the amount of dirt adhering to the upper track 121 reaches a certain value is the electric telescopic drive device activated to move the brush platform 3 downward, and the brush platform motor 6 activated to drive the cleaning brush 5 to perform a cleaning operation on the upper track 121 for a certain period of time. The specific parameters of the aforementioned certain amount of dirt and the certain period of cleaning operation can be adaptively set according to different needs during the implementation of the scheme. After the cleaning operation for a certain period of time is completed, the cleaning operation stops, the brush platform 3 rises and resets, and the brush platform motor 6 stops operating, so that a reasonable distance is maintained between the cleaning brush 5 and the upper track 121, avoiding component wear and energy consumption caused by excessive cleaning.

[0021] To monitor the amount of soil adhering to the upper track in real time, this embodiment installs a pressure sensor 2 on the chassis 1 at a position corresponding to the lower surface of the upper track 121. This pressure sensor can be a SparkFun load cell, a technology already in use, and is equipped with a microcontroller. Specifically, an STM32F103C8T6 microcontroller is used, connecting the pressure sensor to the microcontroller. The microcontroller executes the corresponding function control program through function code written on the host computer. Based on the data monitored by the pressure sensor, it can generate a cleaning start command. These commands are transmitted wirelessly to each electric telescopic drive device and brush motor. This wireless communication transmission technology and components are existing knowledge and will not be elaborated here. The brush platform lifting device is lowered, and the cleaning operation begins. When the cleaning reaches a preset reasonable value, the system automatically stops the cleaning operation, and the brush platform resets.

[0022] The tracked chassis provided in this embodiment is equipped with a device that can intelligently clean the tracked driving surface. This device automatically adjusts the cleaning frequency based on the amount of mud adhering to the track, ensuring normal operation of the tracked chassis in complex terrains such as mountains and hills, improving work efficiency, and extending equipment lifespan. Through real-time monitoring and intelligent control, this device achieves high efficiency and energy saving, reduces manual intervention, and improves the automation level of agricultural operations.
