Description

Technical Field

[0001] The utility model relates to the technical field of weeders, in particular to a mechanical obstacle-avoiding weeder. Background Art

[0002] A mechanical obstacle avoidance weeder is a weeding device that automatically avoids obstacles during weeding. Combining weeding and obstacle avoidance functions, it aims to improve the accuracy and safety of weeding operations while minimizing damage to crops, garden plants, and other obstacles.

[0003] Since mechanical obstacle avoidance is triggered by contact, the weeder may frequently trigger the obstacle avoidance mechanism in areas with a large mixture of weeds and obstacles. Each obstacle avoidance requires stopping the cutting blade or changing the walking direction, which will cause the weeding operation to be constantly interrupted, thus seriously affecting the overall weeding efficiency. To this end, we proposed a mechanical obstacle avoidance weeder. Utility Model Content

[0004] The purpose of the present invention is to provide a mechanical obstacle avoidance weeder to solve the problem raised in the above background technology that since the mechanical obstacle avoidance is triggered by contact, the weeder may frequently trigger the obstacle avoidance mechanism in areas where there are many weeds and obstacles. Each time the obstacle is avoided, the cutting blade needs to be stopped or the walking direction needs to be changed, which will cause the weeding operation to be continuously interrupted, thereby seriously affecting the overall weeding work efficiency. In order to achieve the above purpose, the present invention provides the following technical solutions: A mechanical obstacle avoidance weeder, comprising a weeder body, one side of the weeder body is fixedly connected to a connecting plate, the interior of the connecting plate is provided with two connecting holes, the two connecting holes are symmetrically distributed inside the connecting plate, and the interior of each of the connecting holes is movably connected to a rotating shaft, one side of the connecting plate is movably connected to two connecting frames through the rotating shaft, the two connecting frames are symmetrically distributed on one side of the connecting plate, and the two ends of each rotating shaft are fixedly connected to a limit plate, the two limit plates are symmetrically distributed at the two ends of the rotating shaft, the two limit plates are fixedly connected to the top and bottom of the connecting frame, and the other side of each connecting frame is fixedly connected to a telescopic rod, the two The telescopic rods are symmetrically distributed on the other side of the connecting frame, and the other end of each telescopic rod is fixedly connected to a transmission frame, and the side surfaces of each telescopic rod are respectively fixedly connected to a fixed spring. When the obstacle avoidance auxiliary structure of the lawn mower is used, a hydraulic adjustment structure is formed by the connecting frame, telescopic rod, transmission frame and fixed spring, and the connecting plate, connecting frame and rotating shaft form a rotation adjustment adaptation structure for adaptive adjustment. During the lateral movement for weeding, if there is an obstacle in the middle, the connecting plate, connecting frame and rotating shaft can form a rotation adjustment adaptation structure for adaptive adjustment. Under the action of stress, the connecting frame can be rotated through the rotating shaft, thereby preventing the lawn mower from being blocked by obstacles and reducing work efficiency when weeding.

[0005] Further preferably, one end of each of the fixing springs is connected to the other side of the connecting frame, and the other end of each of the fixing springs is connected to one side of the transmission frame, wherein a slot is provided on the top of one of the transmission frames.

[0006] Further preferably, the bottom of the other transmission frame is provided with a same slot, and the interiors of the two slots are fixedly connected to a fixing platform.

[0007] Further preferably, a connecting shaft is fixedly connected to the bottom of the fixed platform, the connecting shaft is located between the two transmission frames, and the bottom end of the connecting shaft is fixedly connected to the weeding knife body.
