Description
Technical field
The present invention relates to agricultural machinery technological field, specially a kind of rotary cultivator attachment of rotary cultivator.
Background technology
The annual output of the current stalk in China is about more than 6.2 hundred million tons, and only 6% stalk is by returning to the field.It largely discarded, burnt
It burns, environmental pollution and fire hazard is caused to cause damages seriously to national economy.Straw-returning is classified as " rich by the Ministry of Agriculture in recent years
Receipts plan " and the main contents of " fertile_soil plan ", and repeatedly send out emergency notice, it is desirable that crop straw burning is forbidden in various regions, does conscientiously
Good straw-returning and comprehensive utilization work.
Current single-shaft rotary cultivator tilling depth is shallow（Less than 16cm）, the stalk ratio in soil is too high, influences the normal life of wheat
It is long.There are mainly two types of the schemes of solution, a kind of to use ploughing, and also needs multiple working procedure that could plant after ploughing, and spent time is long,
Efficiency is low, is not easy to realize compoundization of operation.It is another still to use rotary tillage, realize stalk by increasing the tilling depth of rotary tillage
Total crop return, can also realize compoundization of operation.Therefore it is still preferable selection using rotary tillage.And existing rotary cultivator,
Such as application No. is 201410243083.7 Chinese invention patent described in a kind of central transmission among the layering of vertical milling formula twin shaft
