Terrain-adaptive parallel lifting mechanism for weeding robot cutter

Abstract

The invention discloses a terrain-adaptive parallel lifting mechanism for a weeding robot cutter, the terrain-adaptive parallel lifting mechanism for the weeding robot cutter comprises a frame, a cutter is arranged on one side of the frame, a lifting mechanism for lifting the cutter is arranged between the frame and the cutter, and the lifting mechanism is arranged on the other side of the frame. A rotating mechanism for realizing swinging of the cutter relative to the frame is arranged between the lifting mechanism and the cutter; in the advancing process of the frame, along with the concave-convex fluctuation of the working slope surface, the cutter is matched with the lifting mechanism and the rotating mechanism, so that the cutter can adapt to different terrain conditions, the function of automatically adjusting the posture of the cutter according to the gravity on the uneven terrain is provided for the cutter, and the service life of the cutter is prolonged.

Description

technical field [0001] The invention relates to the field of special emergency equipment, in particular to a terrain-adaptive parallel lifting mechanism for weeding robot knives. Background technique [0002] At present, the flood control pressure of various water systems in China is increasing day by day, but there is still no reliable and efficient special equipment for clearing obstacles on embankments. At the same time, in all kinds of emergency rescue operations on large slopes with complex terrain such as mountain forest firefighting, which are covered with vegetation (mostly vegetation in the category of shrubs and herbs), front-line personnel often have to face huge Hidden dangers to personal safety, low operating efficiency, and great safety hazards; therefore, problems such as unsatisfactory effects of special operations such as weeding and obstacle removal work under such complex terrain need to be resolved urgently. [0003] There is not yet a series of work eff...

AI Technical Summary

Problems solved by technology

Most of the existing similar working devices are working tools that directly contact the terrain, in which the ground effect of the complex terrain is transmitted back through the direct contact of the tool, and the reaction forces of various directions and sizes often bring huge movement resistance to the overall traveling work of the equipment. , it often needs to consume more unnecessary power to overcome the resistance. At the same time, in the process of overcoming such resistance, it will cause different degrees of stress accumulation and fatigue damage to the tool and various connection structures attached to the tool, which will eventually lead to structural damage. The service life is not ideal, and failures and damage accidents occur frequently
