Technical field
The utility model is related to agricultural machinery engineering fields, and in particular to a kind of weeding dress for weeder between corn plants
It sets.
Background technology
Currently, crops field weeding is broadly divided into three kinds of artificial weeding, weeding by machine and chemical agent weeding.Manually remove
Careless seedling-damaging ratio is low, but can expend a large amount of cost of labor and time, and weeding ratio is not high.Chemical agent weeding is not in wound
Growth of cereal crop seedlings condition, herbicidal effect often spray herbicide using thick mad spray pattern in practice also than more significant, cause energy
Source wastes, if herbicide weeding is used for a long time, weeds in field can generate drug-resistant effect to herbicide, and weeding rate is caused to drop
Low, in addition a large amount of remaining herbicides can not only pollute soil, influence the growth of crops.And weeding by machine is can to hold
A key technology in continuous developing agricultural, starts more and more to be paid attention to, on the current technology, in the ranks weeding technique
More mature, weeding ratio can reach 90% or more, but existing weeding by machine's machine between corn plants for when weeding, hindering seedling
Rate is higher, thus the weeds between corn plants more often use when artificial weeding method.
Existing weeding by machine generally uses tillage and weeding or surface mowing two ways to carry out weeding.Tillage and weeding needs
Machinery carries out shallow-layer overturning, loose surface layer soil to soil, directly roots out inter-row weed, and that there are mechanical volumes is big, weeding is inadequate
Flexibly, the shortcomings that weeding seedling-damaging ratio is high between corn plants and is primarily adapted for use in plains region, can not promote suitable for different terrain
The area of landforms uses.So having prior art has proposed surface mowing formula weeder, this type weeder is usually expert at
The above or below for walking machinery hangs a weeder, and three corner graspers or the mode of rotary cutter are installed in weeder end
Weeding, the weeder of the structure still cannot solve the high technical problem of weeding seedling-damaging ratio between corn plants, and and intertillage
Weeding is compared, and surface mowing formula weeder cannot remove children's grass that just germination grows soil surface, and children's grass is grown up, influenced quickly
The growth of crops.It is low therefore, it is necessary to design a kind of seedling-damaging ratio, young grass can be removed and operation is flexible, the weeding of small volume and less weight
Device.
