Rotten influence later period sowing and germination, are not achieved agriculture requirement, after harvest corn, secondary returning to the field are also needed to handle, waste work
When.2, blade type installs Y type moving knife on cutter shaft, installs the trapezoidal stationary knife of multiple groups, in cutter shaft operation process, Y type on the rack
Moving knife is mutually inserted with trapezoidal stationary knife, so that stalk is ground into filiform, but consumption power is larger, on the other hand, in crushing process
In, the miscellaneous stone of hard plant or field is encountered, is easiest to make trapezoidal stationary knife damage deformation, touches Y type moving knife mutually with trapezoidal stationary knife
It hits, influences normal use, replacement, maintenance are more troublesome, and increase use cost.
Summary of the invention
Problem to be solved in the utility model is, 1, eliminate the crushing disadvantage of hob type, blade type；2, reach agronomy to want
It asks, reduces production and use cost.
The utility model precisely in order to the defect that solves the above problems, provide a kind of maize harvesting machine straw stalk pulverizing knife head and
Device.
The utility model adopts the following technical solution realizes.
Straw stalk pulverizing knife head used in a kind of maize harvesting machine, the utility model cutter head include there are three blade three
A blade is arranged side by side；Intermediate blade is set as straight knife in three blades, and the tool bit part that the blade on both sides is set as is outside
The shape of bending forms the Y word knife of " Y " font that is, after the blade unit on both sides；Three blades are fixedly connected at insert bottom；
The blade of three blades is provided with two side edges of blade or more.
It is further that three blades described in the utility model are fixedly connected at insert bottom, each blade in junction
Between be provided with fixed block.
Using a kind of device of straw stalk pulverizing knife head used in maize harvesting machine, the utility model device is arranged at this
On left and right supporting plate below the ceding of Taiwan of maize harvesting machine；It is provided with bearing block and bearing on the supporting plate inner wall of left and right, in bearing
It is equipped with the cutter shaft of rotation, tool apron is fixedly installed on cutter shaft, cutter head bottom is fixed on tool apron by pin shaft and is made
For moving knife setting.
It is further when the utility model is immediately ahead of tool apron forward rotating knife cutter shaft, to be arranged at the cutter head on cutter shaft
In the state perpendicular to ground.
It is further that moving knife is arranged in intervening portion on the position that the utility model cutter shaft outer surface is often rotated by 90 °.
It is further that the utility model device further includes several stationary knifes, i.e., it is fixed on the ceding of Taiwan rear wall at cutter shaft rear portion
It is provided with arc panel, square steel is fixedly installed on arc panel, cutter head is horizontally set on conduct on arc panel by square steel fixation
Stationary knife setting, stationary knife are located at the top of cutter shaft.
The beneficial effects of the utility model are 1) the utility model is fine to corn stover cutting effect, and it can be upright, vertical
Corn stover that is horizontal, tilting, skew effectively is crushed, and toothing rate is extremely low, good crushing effect, and it is smaller to consume power；
2) in operation, stationary knife, moving knife are mutually touched caused by can effectively reducing because of hard plant, tree root, miscellaneous stone in milpa etc.
It hits and forms deformation；3) the utility model production installation, maintenance and its conveniently, greatly reduces production cost, reduces portion
Part damage, service life are longer.4) the utility model can be simple with structure, easy to assembly, of less demanding to technical staff, can be with
It is promoted in vast corn planting area.
The utility model is further explained with reference to the accompanying drawings and detailed description.
