Obstacle avoidance rack of hedge shears

Abstract

The invention discloses an obstacle avoidance rack of a pair of hedge shears. The obstacle avoidance rack comprises a tool holder, a measuring arm, a measuring rod, an angle detection device, a swing arm, a rack, a second rotating shaft and a driving mechanism, wherein the tool holder is used for mounting the shears; a measuring seat is arranged on the front side of the left end of the tool holder; the left end of the measuring arm is fixedly connected with a first rotating shaft; the first rotating shaft is arranged on the measuring seat in a rotating manner; the right end of the measuring arm is connected with the tool holder through an elastic mechanism; the measuring rod is transversely arranged in front of the tool holder; the left end of the measuring rod is fixedly connected with the right end of the measuring arm; the angle detection device is connected with the first rotating shaft; the right end of the swing arm is fixedly connected with the top of the tool holder; the rack is positioned on the upper side of the swing arm; the lower end of the second rotating shaft is fixedly connected with the left end of the swing arm; the second rotating shaft can sleeve the left end of the rack in the rotating manner; the driving mechanism is used for driving the second rotating shaft to rotate. According to the obstacle avoidance rack, automatic obstacle avoidance can be flexibly realized; the obstacle avoidance rack has a simple structure and is convenient to use.

Description

technical field [0001] The invention relates to the field of hedge trimmers, in particular to an obstacle avoidance frame for hedge trimmers. Background technique [0002] The trimming of hedges on both sides of the road has a long journey and a large workload. Therefore, vehicle-mounted hedge trimmers are often used for trimming hedges, which have high work efficiency and good trimming quality. However, the vehicle-mounted hedge trimmers are less flexible than manual trimming. The pruning tool does not have the function of automatic obstacle avoidance. For some obstacles such as utility poles or light poles in the hedge, its avoidance mainly depends on the driver's observation to avoid them in advance. When the driver is negligent or unable to observe the thick and hard When there are obstacles such as broken branches or tree trunks, the pruning tool cannot automatically avoid obstacles flexibly, which may easily cause the pruning tool to directly hit the obstacle, resultin...
