Description
Technical field
Main body is crushed the utility model relates to agricultural mechanical field more particularly to a kind of stalk and master is crushed using the stalk
The chopping and returning device of body.
Background technique
Straw-returning increases the soil organism, increases soil fertility, prevent crop straw burning and make with that can improve soil texture
At many merits such as atmosphere pollution, gradually popularized and produce good economic benefit, ecological benefits and social benefit.
The major way of northern China Dryland maize straw at present are as follows: corn harvesting machine is in harvesting corn fringe
While by stalk pulverization process and shedding in earth's surface, the later period is turned over by rotary tillage soil-working machinery bury again, is rotted to reach stalk
The purpose of decomposition.This is that the simplest method of current straw-returning and various regions are widelyd popularize, using most modes.But it is main
The corn harvesting machine of stream, all will high speed, efficiently picking corn fruit using operation from being designed into because operation timeliness, operating condition etc. limit
Fringe can not be really achieved the requirement of straw-returning to the pulverization process of stalk as emphasis.It is mainly shown as: 1, after crushing
Stalk too long (4~10 centimetres), excessively thick, shed concentration, when later period rotary tillage soil-working, concentrate blocked up stalk that cannot turn over and bury
And rake is not firm, influences site preparation quality；2, stalk hinders sowing when sowing, and causes the disconnected ridge that is short of seedling；3, too long excessively thick stalk is long-term
It can not rot, cause soil hanging, deep subsoil moisture is hindered to transmit upwards, influence emergence or growth of seedling.
Utility model patent if notification number is CN2879635Y discloses a kind of double side-edge drive corn straw smashing also
Field machine, including power input shaft are connect with gearbox, jack shaft left and right ends respectively with the first transmission mechanism and second
The connection of transmission mechanism top, the left and right ends of cutter shaft are connect with the first transmission mechanism and the second transmission mechanism lower part respectively, cutter shaft
