Description
Technical field
The invention belongs to weeding apparatus technical fields, and in particular to a kind of multipurpose weed harvesters.
Background technique
Weeds refer to the plant for being grown in and being harmful to human survival and space for activities, be generally non-cultivation wild plant or
The plant that the mankind are hindered.
Grass trimmer（Lawn mower）Also known as weeder, grass mower, lawn mower etc..Grass trimmer is a kind of for trimming
The machine tool of lawn, vegetation etc., it is by cutterhead, engine, traveling wheel, walking mechanism, blade, handrail, control unit grouping
At.
Cutterhead is equipped with engine, blade is housed on the output shaft of engine, blade utilizes hair on traveling wheel on cutterhead
The high speed rotation of motivation improves much in terms of speed, saves the activity duration of weeding worker, reduces a large amount of manpower money
Source.
Currently there are the grass trimmers of numerous species, but part grass trimmer needs palm top, and inconvenience carries out for a long time
Work, part grass trimmer in operation can be because of the work of excessive effect of jitter operator.
Summary of the invention
The purpose of the present invention is to provide a kind of maintenance cost is low, shockproof properties are excellent, and it is high that weeds gather in clean degree, harvesting
It is high-efficient, it is conducive to soil resource and develops and uses, and can realizes the multipurpose weed harvesters of the management care to lawn.
The technical solution that the present invention is taken to achieve the above object is：Multipurpose weed harvesters, including motor, motor
