Multifunctional green fence pruning manipulator capable of reconfiguring rapidly

Abstract

The invention discloses a multifunctional green fence pruning manipulator capable of reconfiguring rapidly. The multifunctional green fence pruning manipulator capable of reconfiguring rapidly comprises a rotary chassis, a base, a large arm, a rear arm, an overload protective mechanism, a front arm, a small arm connecting frame, a rotary shaft, a small arm, a trimming cutter head connecting frame, a trimming cutter head, a large arm push rod, a rear arm push rod, a small arm push rod as well as a rotary power motor, wherein the rotary chassis is fixedly installed on a bearing vehicle; the base is fixedly installed on the upper end surface of the rotary chassis; the large arm is articulated with the base; the rear arm is articulated with the large arm; the overload protective mechanism is connected with the tail end of the rear arm; the front arm is connected with the overload protective mechanism; the small arm connecting frame is articulated with the tail end of the front arm; the rotary shaft is installed on the small arm connecting frame; the small arm is fixed on the tail end of the rotary shaft; the trimming cutter head connecting frame is articulated to the tail end of the small arm; the trimming cutter head is fixed below the trimming cutter head connecting frame; the large arm push rod is used for driving the large arm to swing back and forth; the rear arm push rod is used for driving the rear arm to pitch up and down; and the small arm push rod is used for driving the small arm to overturn up and down; and the rotary power motor is used for driving the rotary shaft to rotate. The multifunctional green fence pruning manipulator capable of reconfiguring rapidly provided by the invention has an overload protection function of trimming load, replaces different tools according to different trimming types, and can trim and mold landscape trees with any shape.

Description

technical field [0001] The invention relates to a machine for pruning and modeling of road hedges and gardening landscape trees, in particular to a machine capable of automatically trimming hedgerows and gardening landscape trees in any shape such as plane, wave, conical, cylindrical, spherical, etc. A rapidly reconfigurable multifunctional hedge seedling pruning manipulator. Background technique [0002] Greening pruning is a heavy work, especially hand-held pruning. Greening workers hold or carry hedge trimmers to carry out pruning operations, which consumes a lot of energy and low work efficiency. For example, pruning a ball with a diameter of 1.2 meters requires 2 to 3 It takes 5 to 10 minutes for a pruning worker to carry out together, and pruning taller cylindrical, conical trees, etc., also needs to build a platform, etc., which is more time-consuming and laborious. In addition, the noise and vibration of the machine have a greater impact on the health of the pruning ...

AI Technical Summary

Problems solved by technology

[0005] In addition, due to the pruning process, some unscheduled factors will cause the pruning machine to bear a larger load than normal pruning operations, such as pruning tool wear, cutting to branches larger than the maximum allowable branch diameter, pruning speed too high Fast and so on, all lead to a sharp increase in cutting resistance

Excessive cutting resistance will shorten the life of the parts of the trimmer or even cause catastrophic consequences such as fracture and damage
