On rack both side plate outer wall lower part, pivot pin is inserted on rear side of rack both side plate on position, and elastic rack formula is kept off careless grid and is mounted on
On pivot pin；Its structure is simple, and manufacturing cost is cheap, manipulates simple and convenient, and using reliable, the buried effect of stalk is good, saves power
Consumption, ground flat degree is high after operation.
For another example, application No. is 2017108882371 Chinese invention patents, disclose a kind of straw stubble crushing and returning to field machine,
Including rack, power-transmission system, wedge-shaped furrowing blade, pick up disintegrating mechanism, covering suppression system；The power-transmission system position
In front end of rack top, wedge-shaped furrowing blade is located at front end of rack lower part, picks up disintegrating mechanism and is located at central rack, covering suppression system
System is located at rack rear portion, and power is reached by power-transmission system and picks up disintegrating mechanism and covering suppression system by complete machine power device
The straw stubble that the excavation of wedge-shaped furrowing blade is got up is carried out pickup crushing by picking up disintegrating mechanism, finally by covering town by system
Pressure system carries out overturning returning to the field.Simple, easy to operate, economic and practical, suitable for straw stubble the chopping and returning of its structure, before
Wedge-shaped furrowing blade be able to achieve the excavation to root stubble, behind pick up the pickup that had both been able to achieve to straw stubble of disintegrating mechanism can also
It realizes pulverization, then covers suppression system and the root stubble of crushing is overturned, be buried in the earth, then carry out prepartion of land town
Pressure.
The chopper of aforementioned two patent disclosure is able to satisfy the needs of chopping and returning substantially, but in actual use,
Since stalk is anyhow different, in chopping and returning, the stalk that not pulverized knife switches to is easy to upwarp, and is wrapped in and crushes knife handle and lead
On roller, cause the effect of subsequent straw-returning poor, stalk buried depth is inconsistent, must stop at regular intervals by the straw of winding
Stalk removal, it is time-consuming and laborious.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned prior art, provides a kind of high-efficient and can be reduced stalk winding
