Obstacle avoidance type trimmer

Abstract

The invention discloses an obstacle avoidance type trimmer. The obstacle avoidance type trimmer is characterized in that a shearing part is arranged at the front end of a swing arm; a supporting seat is arranged on the shearing part, a shearing driving part is arranged on the supporting seat, a fixing shaft is arranged at the bottom of the supporting seat, a cutting supporting frame capable of rotating around the fixing shaft and a driving wheel are arranged on the fixing shaft, and driving is achieved through connection of the driving wheel and the shearing driving part; a plurality of branches are arranged on the cutting supporting frame, a vertical sleeve is arranged at the end of each branch, a cutter head driving core is arranged in each vertical sleeve, a cutter head and a driven wheel are arranged at the two ends of each cutter head driving core respectively, and the driven wheels and the driving wheel are connected to achieve driving. Through the structural arrangement, the cutter head on the cutting supporting frame is driven by the driving wheel to achieve rotary cutting, and when an obstacle is encountered, the cutting supporting frame achieves avoidance around the fixing shaft; and a lead screw pair is further arranged on the supporting seat and matched with a hinge rod to achieve adjustment of lifting and lowering of the supporting seat.

Description

technical field [0001] The invention relates to the technical field of roadside green plant pruning equipment, in particular to an obstacle-avoiding pruning machine. Background technique [0002] As we all know, there are side roadblocks and green plants on the sides of the current national highways and expressways. When pruning green plants, pruning machines are usually used to repair branches and weeds. However, the actual problem encountered at present is that existing Advanced pruning machines can only mow large areas of ground weeds, but weed cutting operations cannot be achieved in areas with protective barriers on the roadside, and can only be repaired manually. [0003] As a technician in this industry, it is very necessary to design an obstacle-avoiding pruning machine, which can stably avoid roadblocks and realize obstacle avoidance while repairing weeds on the ground, so as to realize the removal of weeds around roadblocks. Cutting is a technical problem to be so...
