Description
Technical field
The invention belongs to agricultural machinery technological fields, and in particular to a kind of portable mowing stump extractor.
Background technology
The weeds grown therewith during crop growth can influence the development of itself, therefore weeding operation becomes
An essential measure in crop-planting can provide excellent growing conditions by weeding operation to crop.
Farmland weeding mode mainly has artificial weeding, chemical weed control and weeding by machine at present.Wherein, artificial weeding labour is strong
Degree is big, and speed is slow, and efficiency is low, therefore cost of labor is high, and large-scale farm is it occur frequently that because artificial deficiency leads to the speed of weeding
Less than weeds the speed of growth the case where, seriously affect the speed of growth of crop, even result in part plot total crop failure.Chemical weed control
It is the growth applied herbicide during plant growth and inhibit weeds, efficient although effect is good, at low cost, agriculture
Medicine remains the quality that can reduce crops, and contaminated soil and water source, destroys ecological environment.Existing small portable weeding
Machinery is sheared mainly for stem of the weeds more than soil and blade, is also easy to send out during weeds are cleared up in shearing
Life twines careless situation, causes weeding ratio low, there are security risk, and such small portable weeding machine not to weeds in soil
Root system inside earth is cleared up, and causes the speed that weeds regrow fast, needs to be removed again again after certain interval of time
Grass.The large-scale weeding machine having in the market can either shear the stem and blade of weeds, and can destroy the root of weeds, and
Work efficiency is high, but since its own volume is big, weight is big, can only be promoted the use of in plains region, can not be applied to
The vast Mountain Area of Southwest knob in China.Solving problem above becomes the task of top priority.
Invention content
In order to solve the above technical problems, the present invention provides a kind of light-weight, small, and operation is flexible, and weeding ratio is high, both
Weeds stem blade, which can be removed, again can remove the portable mowing stump extractor of weeds root system.
To achieve the above object, technical solution of the present invention is as follows：
