Description
Technical field
The utility model belongs to small agricultural and graden machine field, more particularly, to one kind be used for clear up farmland, gardens,
The fast high-speed type grass-remover of the weeds velocity of rotation of ridge, roadside etc..
Background technology
Weeds in farmland can draw the fertilizer of land limited, and the growth to crops impacts, and causes it to yield poorly,
In order to root out weeds, weeds can be removed by way of artificial weeding, this mode efficiency of hoeing up weeds is low, and it is longer not only take up operator
Time, and the body of operator is caused damage.
Also there is small-sized grass-remover in the market, it can liberate the double of weeder by electronic mode weeding by machine
Hand, improves weeding ratio, but there is also it is following more the shortcomings that：1）Using worm reduction box structure, knife of hoeing up weeds installation
In reduction box both sides, its speed reducing ratio is typically 40：1, swivel speed of hoeing up weeds is relatively low, it is such machinery using portable miniature gasoline engine as
Power, its power points rotating speed is generally 6500-7000r/min, and after deceleration, the rotary speed for knife of hoeing up weeds is in 162-175 r/
Min, rotating speed is too low not to smash grass, particularly grass roots when causing to cut off grass, easily produces what part weeds were brought back to life again
Situation；2）There is no antiwind structure, weeds easily wind cutter shaft, cause machine cisco unity malfunction, and cleaning is wasted time and energy；3）Hoe up weeds
Knife is installed on the cutter shaft of reduction box both sides, is cantilever structure, can be because of both sides discontinuity equalization when running into the ground of out-of-flatness
And influence operation；In addition, influenceed by this structure, can be left among the tine of left and right a hoe less than area；4）Because of knife of hoeing up weeds
Rotating speed is relatively low to cause operating efficiency low.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides one kind and hoed up weeds thorough, efficient, labour-saving high-speed type hoe
Careless machine.
