Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, specifically, it relates to a tracked chassis for a weeding robot. Background Technology

[0002] Weeds have extensive root systems and a strong ability to absorb nutrients and water from the soil. They often compete with crops for sunlight, water, nutrients, and space in the field, leading to a decline in crop yield and quality. Moreover, weeds carry diseases and pests, causing crop diseases and pests, resulting in huge losses to the agricultural economy. Currently, common weeding methods include manual weeding, chemical weeding, and mechanical weeding. Manual weeding is more precise and suitable for small-scale complex environments, but it is labor-intensive and inefficient. Chemical weeding uses herbicides to control weeds over large areas and is easy to operate, but excessive use of herbicides can lead to increased herbicide resistance in weeds, environmental pollution, and may cause soil compaction. Mechanical weeding is environmentally friendly and leaves no residue, but it can easily damage crops and has low weeding efficiency.

[0003] Chinese utility model patent CN220465650U discloses a tracked chassis for a laser weeding robot, including a load-bearing platform, a support frame, a track assembly, a chassis motor, and a chassis battery pack. The top surface of the track assembly has a mounting housing, and the support frame, chassis motor, and chassis battery pack are mounted on the top surface of the mounting housing. The chassis battery pack is connected to the chassis motor, and the output end of the chassis motor is connected to the track assembly via chain drive. The track assembly, support frame, chassis motor, and chassis battery pack constitute a track module. Two track modules are symmetrically arranged at the bottom of the load-bearing platform. The top of the support frame is mounted on the load-bearing platform. Multiple horizontally arranged positioning holes are opened at the connection between the load-bearing platform and the support frame, and the support frame is fixed to the positioning holes of the load-bearing platform by two sets of bolts.

[0004] The aforementioned existing technology also has the following drawbacks: when it is necessary to adjust the distance between the two tracks, the tracks need to be removed and then reinstalled, and the distance between the two tracks cannot be adjusted anytime and anywhere.

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when adjusting the distance between the tracks on both sides is required, the tracks must be removed and then reinstalled, making it impossible to adjust the distance between the tracks on both sides anytime and anywhere, the present invention adopts the following technical solution.

[0007] A tracked chassis for a weeding robot includes two opposing movable tracks. A connecting beam is detachably connected to the opposite surfaces of the two movable tracks. A mounting top plate is installed above the connecting beam. Lifting components are installed on the two connecting beams. The lifting components lift the two movable tracks upward. A moving component is installed at the bottom of the lifting components. The moving component enables the two movable tracks to move towards each other or in opposite directions.

[0008] Preferably, an adjustment assembly is installed on the top plate, which allows the two moving tracks to move simultaneously towards or in opposite directions.

[0009] Preferably, a support assembly is installed between the connecting beam and the mounting top plate.

[0011] Preferably, the movable component includes a mounting bracket and a movable wheel. Multiple mounting brackets are fixedly connected to the bottom of the connecting cross plate, and a movable wheel is rotatably connected inside each mounting bracket. Multiple sliding rods passing through the connecting beam are fixedly connected to the upper end of the connecting cross plate, and a limit plate is fixedly connected to the upper end of every two sliding rods.
