Description

A trimming machine for pruning road surface and lawn juncture

Technical Field

The invention belongs to the field of greening pruning mechanical equipment, and particularly relates to a pruning machine for pruning a junction between a road surface and a lawn.

Background

The lawn trimmer is a mechanical tool for trimming lawns, vegetations and the like, and consists of a parallel four-rod lifting device, a rack, a left single-wing weeding device, a right single-wing weeding device, a whole machine deviation adjusting device, a comb tooth rotating conical gear speed increasing transmission mechanism and a comb tooth profiling depth adjusting device; the efficiency is improved by 8 to 10 times compared with the manual weeding, the seedling injury rate is low, and the seedling removing and cleaning rate is high. The weeding machine consists of a cutter head, an engine, a traveling wheel, a traveling mechanism, blades, handrails and a control part, wherein the cutter head is arranged on the traveling wheel, the engine is arranged on the cutter head, the blades are arranged on an output shaft of the engine, the blades are greatly improved in speed by utilizing the high-speed rotation of the engine, the operation time of weeding workers is saved, and a large amount of manpower resources are reduced.

At present, lawn trimmers produced at home and abroad can be divided into three types, namely a manual backpack lawn trimmer, a motorized walking lawn trimmer and a manual driving lawn trimmer, wherein the manual driving lawn trimmer is time-saving, labor-saving and high in working efficiency, but is not suitable for occasions with large inclined gradient. At present, the two lawn trimmers can only be adopted for operation, and the defects of low working efficiency, high labor intensity, short service life of the lawn trimmer and the like exist due to poor working conditions.

Common lawn mowers are mainly classified into power type lawn mowers and manual type lawn mowers, wherein an engine is mounted on the lawn mowers, and a cutting knife unit is driven to rotate by the engine, so that when a user pushes the lawn mowers on a lawn, the user can automatically perform mowing action, and even if the lawn mowers do not move, the engine and the cutting knife unit still keep running states; the manual mower has no power source such as an engine, and the manual mower has the advantages that when a user pushes the mower, wheels or friction wheels are made to rub on a lawn to roll, and then the wheels or the friction wheels are utilized to drive a cutting knife unit at the bottom of the mower to rotate simultaneously, so that only when the user pushes the mower forwards, the cutting knife unit can perform mowing action, if the mower is static, the cutting knife unit can not rotate, but the conventional manual mower is provided with a plurality of rotating shafts which are connected with each other and rotate, external gears which are mutually transmitted are arranged among the rotating shafts, and a plurality of external gears are respectively combined on the wheels and the rotating shafts, so that the cutting knife unit can rotate through the transmission of the plurality of external gears and the rotating shafts which are stacked layer by layer, so that the manual mower has a huge structure and a quite complex transmission mechanism, and parts at each part are easy to damage, which causes a quite troublesome maintenance, the manufacturing and maintenance costs are high.

However, the border between the lawn and the pedestrian road is usually divided by using curbs or shorter stones, the grass at the edge of the lawn can grow and extend to the pedestrian road surface due to the growth of the grass for a long time, which not only greatly affects the overall aesthetic degree but also hinders the walking of people.
