This invention discloses an inter-plant weeding machine, belonging to the technical field of weeding equipment. It includes: a frame with rotatable wheels on both sides; a crossbar located at the front of the frame, with two connecting frames slidably mounted on the crossbar. A rotating shaft is rotatably connected to each connecting frame, and a main weeding roller is mounted on the rotating shaft. A driven roller adapted to the main weeding roller is also mounted on each connecting frame; two drive mechanisms and two linkage mechanisms are all mounted on the frame. This invention uses the drive mechanisms to rotate the rotating shaft and the main weeding roller, which, in conjunction with the driven rollers, clamps and pulls out weeds, achieving continuous weeding without the use of herbicides and pesticide residues. It also better replaces manual weeding, significantly improving work efficiency. The driving wheels drive the linkage mechanisms, causing the two connecting frames to reciprocate along the crossbar in opposite directions / away from each other, allowing the main weeding roller and driven roller to enter between crop plants to remove weeds in the gaps between plants, significantly improving the weeding effect.
