Description

Hand-held mower anti-sticking grass device based on gardens are pruned

Technical Field

The invention relates to the technical field of mowing equipment, in particular to a grass clamping prevention device of a hand mower based on garden pruning.

Background

Mowers are also known as weed trimmers, lawnmowers, lawn trimmers, and the like. The mower is a mechanical tool for trimming lawn and vegetation, and is composed of cutter head, engine, walking wheels, walking mechanism, blades, handrail and control unit. The cutter head is arranged on the travelling wheel, the engine is arranged on the cutter head, the blade is arranged on the output shaft of the engine, the blade is 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. With the rapid rise of the lawn industry, china began to use power-storing reciprocating mowers in the 21 st century. At the end of the 19 th century, it was a very physical effort to protect a lawn. For example, in a large farm in a village in the west of bavaria, germany, 50 of these people are lawn care if 200 workers are employed. In the season of grassland overgrowing, grass cutting is required approximately once every ten days. Mowers hold very long implements, sickles: the blade is serrated, requiring a sharpening stone to sharpen it, often used, to cut grass (in effect, working more like sawing grass with a saw). After the work is finished, the lawn is full of sawn grass leaves, and then the grass leaves on the ground are picked up to be used for feeding cattle and sheep on the farm, so that the time is saved, and the damage to the lawn is reduced. Consists of a parallel four-bar lifting device, a frame, a left single-wing weeding device, a right single-wing weeding device and a whole machine deviation adjusting device.

For example, patent No. CN111771515A discloses an anti-grass-jamming mechanism of a hand mower for garden trimming, which comprises a control block, a holding rod is fixedly connected to the top of the control block, a rotating shaft is movably connected to the bottom of the control block, and a blade is fixedly connected to the bottom of the control block. This a hand-held lawn mower anti-sticking grass mechanism for gardens are pruned rotates the carousel and makes the carousel drive the dwang motion, further makes three gears drive two rotations of gear, and the axis of rotation can up-and-down motion under the effect of loop bar this moment, further makes the tool bit can up-and-down motion to the effect that the tool bit height of lawn mower can be adjusted has been reached. When the rotating disc rotates under the drive of the rotating shaft, the blades can cut the plastic bags and the weeds close to the rotating shaft, and then the plastic bags and the weeds are thrown away under the action of centrifugal force, so that the effect that sundries cannot be wound on the cutter head is achieved.

In the present anti-sticking grass device use, prevent that grass winding is on the cutting knife mostly, can't be better prevent that the plastic bag winding is on the cutting knife, because of the elasticity and the tensile properties of plastic bag are stronger, still can twine in the cutting knife pivot very easily, increase the resistance when pivot rotates, cause motor speed to reduce, the electric current increase leads to the motor to burn out, finally causes the unable normal use of anti-sticking grass device.
