[0027] Please see Figure 1-5 This utility model provides a technical solution: a tracked orchard weeder, including a main body 1, a weeding component 2, and a buffer component 3. The weeding component 2 consists of two sets, which are arranged on both sides of the front end of the main body 1. The buffer component 3 is mounted on each weeding component 2. Each weeding component 2 includes a first adjusting arm 21, with a second adjusting arm 22 movably mounted on its upper end. The buffer component 3 is located at the lower end of the second adjusting arm 22. A weeding motor 23 is located at the lower front end of the buffer component 3. 3 includes a fixed base 31, which is installed on the lower front side of the second adjusting arm 22. An upper buffer bracket 32 ​​is fixed to the lower end of the fixed base 31, and a lower buffer bracket 33 is movably installed on the side of the upper buffer bracket 32. The upper buffer bracket 32 ​​and the lower buffer bracket 33 are hollow structures. A tension spring 34 is fixed to the lower end of the lower buffer bracket 33. An adjusting rod 35 is provided inside the fixed base 31. The adjusting rod 35 passes through the upper end of the upper buffer bracket 32, and the upper end of the tension spring 34 is connected to the lower end of the adjusting rod 35.

[0028] During use, the fixed base 31 secures the entire buffer assembly 3, ensuring a stable connection between it and the weeding assembly 2. The upper buffer bracket 32 ​​serves as the upper support structure for the buffer assembly 3, working in conjunction with the lower buffer bracket 33 to transmit the impact force and guide the rotation and bending of the lower buffer bracket 33. The tension spring 34 is stretched upon impact, absorbing impact energy through elastic deformation while providing restoring force, allowing the buffer assembly 3 to return to its original position after impact. By rotating the adjusting rod 35, the initial tension of the tension spring 34 can be adjusted, thereby controlling the buffering strength and flexibility of the buffer assembly 3 to adapt to different operating environments. The height and angle of the weeding assembly 2 can be adjusted through the movable connection of the adjusting arm.

[0029] A contact sensor 36 is provided on the lower side of the lower buffer bracket 33. When not in use, the contact sensor 36 is in contact with the lower end of the upper buffer bracket 32. When the contact sensor 36 detects a collision signal, it will immediately transmit the signal to the machine's control system. Based on the feedback from the sensor, the control system can quickly determine whether the machine needs to be shut down or slowed down.

[0030] The main body 1 of the device includes a support base 11, and a drive assembly 12 is provided on both sides of the support base 11. The drive assembly 12 includes a drive wheel 121, which is fixed on both sides of the support base 11. A drive track 122 is provided on the outer side of the drive wheel 121. The drive assembly 12 provides power and mobility to the weeder through the cooperation of the drive wheel 121 and the drive track 122.

[0031] A drive motor 125 is connected to the side of the drive wheel 121. Multiple sets of support wheels 123 are provided at the lower ends of both sides of the support base 11. The multiple sets of support wheels 123 are located inside the lower end of the drive track 122. A motor protective shell 126 is provided on the outside of the drive motor 125. The drive motor 125 provides a direct power source to the weeder through its connection with the drive wheel 121. The multiple sets of support wheels 123 are located inside the lower end of the drive track 122 and are mainly used to assist in supporting the weight of the weeder and provide additional balance support. The motor protective shell 126 is located on the outside of the drive motor 125 and can effectively protect the drive motor 125 from external environmental corrosion and damage.

[0032] A wheel baffle 124 is provided on the upper end of the drive track 122. The wheel baffle 124 is fixed on both sides of the upper end of the support base 11. The wheel baffle 124 is located on the upper end of the drive track 122 and can prevent debris in the orchard from being rolled into the drive track 122.

[0033] A control box 13 is installed on the upper end of the support base 11, and a power supply box 14 is installed inside the upper end of the support base 11. An upper protective shell 15 is installed on the upper end of the support base 11. The control box 13 and the power supply box 14 are located inside the upper protective shell 15. The control box 13 is used for centralized control and intelligent management, and the power supply box 14 is the power supply center of the weeder. The upper protective shell 15 can effectively protect the control box 13 and the power supply box 14 from the corrosion and damage of the external environment.

[0034] The lower buffer bracket 33 has a weeding motor 23 fixed at its lower end. The lower end of the weeding motor 23 has a motor drive disk 24 installed at its lower end. Weeding blades 241 are movably installed around the outer side of the motor drive disk 24. The weeding blades 241 are movably installed around the outer side of the motor drive disk 24, forming a circumferential blade structure. The weeding blades 241 can cut weeds in the orchard by rotating at high speed. When in use, they have a certain buffering effect in the event of a collision. When not in use, they reduce the danger caused by exposed blades.

[0035] As one embodiment of this utility model: when a collision occurs during the use of the tracked orchard weeder, the collision force is first transmitted to the buffer component 3 of the weeding component 2. Through the buffer component 3, the tracked orchard weeder can effectively absorb the impact force when encountering obstacles, reducing the damage caused by rigid collisions. The buffer component 3 includes a fixed base 31, an upper buffer bracket 32, a lower buffer bracket 33, and a tension spring 34. When in contact with an obstacle, the brackets relieve the impact by deforming and bending, and the tension spring 34 further absorbs energy, preventing damage to the machine or damage to surrounding objects. In addition, the adjusting rod 35 allows the spring tension to be adjusted according to the terrain, enhancing the adaptability and stability of the equipment.

[0036] When the contact sensor 36 detects a collision signal, it immediately transmits the signal to the machine's control system. Based on the feedback from the sensor, the control system can quickly determine whether the machine needs to be shut down or slowed down. After adjustment, the tension spring 34 absorbs energy and pulls the lower buffer bracket 33 back to its original position through its own restoring force, so that the buffer assembly 3 can quickly return to the non-collision state. The setting of the adjustment lever 35 allows users to adjust the initial tension of the tension spring 34 according to the terrain or operation requirements, thereby controlling the buffering strength and flexibility of the buffer assembly 3.
