Disclosed in CN203748275U, name is called the utility model patent of " for the movable arbor of stalk cutting and returning machine, stalk cutting and returning machine and Harvester for maize ", it includes: have the rotor of cylindrical surface, and this rotor rotates around the central axis of described periphery；Being arranged on the multiple tool rests on rotor, each tool rest is provided with bearing pin；And multiple cutting knife, it is arranged on the tool rest of correspondence respectively through bearing pin, and each cutting knife can rotate around the axis of corresponding bearing pin, the axis of bearing pin is each parallel to central axis, multiple tool rests are distributed uniformly and circumferentially on the cylindrical surface of rotor so that the interval angles between the axis of the bearing pin of two tool rests adjacent on the circumferencial direction of rotor is equal；And spacing distance between adjacent two tool rests is equal in central axial direction.
Although straw all can be pulverized by the straw-returning chipper in above-mentioned patent, but the straw-returning chipper in said structure is after to straw chopping, all exist and throw underspeed, shed uneven problem, cause that peasant brings inconvenience in overall, arable land, fertilising and seeding process, reduce the farming efficiency of peasant.
Utility model content
The purpose of this utility model is just to provide one and enables to the uniform stalk cutting and returning machine of straw scattering draught.
The purpose of this utility model is realized by such technical scheme, a kind of stalk cutting and returning machine, including housing, it is provided with cutter shaft in described housing, the drive system being connected with cutter shaft it is provided with in one end of described cutter shaft, the outer wall of described cutter shaft is provided with multiple equidistant tool rest with cutting blade by screwdriven track, on the outer wall of described cutter shaft and by each tool rest, is vertically arranged with an aerofoil.
Wherein, the run trace that the plurality of aerofoil is linked to be is parallel with the run trace of tool rest.
Further describing, described aerofoil is the arc of isosceles triangle or isosceles trapezoid.
Wherein, on the same circumference of described cutter shaft, angle a between vertical centrage and the tool rest longitudinal section of aerofoil is 100 °～130 °.
In order to support and reinforce aerofoil, it is provided with the reinforcing plate being connected with aerofoil at the vertical aerofoil in the back of described aerofoil.
In order to ensure stress equalization, described reinforcing plate is provided with circular hole, by arranging securing member on circular hole, it is possible to play satisfying dynamic equilibrium requirement.
Owing to have employed technique scheme, this utility model has smart structural design, with low cost, service-strong advantage, adopt it to enable to the straw after pulverizing to throw speed, shed uniformly, for follow-up whole, plough, fertilising and sowing bring convenience, and improve farming efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail; but this utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or replacement, still fall within this utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of stalk cutting and returning machine, including housing 1, it is provided with cutter shaft 2 in described housing 1, the drive system 3 being connected with cutter shaft 2 it is provided with in one end of described cutter shaft 2, the outer wall of described cutter shaft 2 is provided with multiple equidistant tool rest 5 with cutting blade 4 by screwdriven track, on the outer wall of described cutter shaft 2 and by each tool rest 5, is vertically arranged with an aerofoil 6.
Wherein, the run trace that the plurality of aerofoil 6 is linked to be is parallel with the run trace of tool rest 5.
As shown in Figure 4,5, in this utility model, described aerofoil 6 is the arc of isosceles triangle or isosceles trapezoid.
As shown in Fig. 6,7,8,9, in order to reach to throw speed preferably and make to throw more uniform, the angle a between the vertical centrage and tool rest 5 longitudinal section of aerofoil 6 on the same circumference of cutter shaft 2 is 100 °～130 °.
Wherein, when angle a is 125 °, its effect is best.
In order to reinforce aerofoil, at the back of described aerofoil 6, vertical aerofoil 6 is provided with the reinforcing plate 7 being connected with aerofoil 6.
Further, described reinforcing plate 7 is provided with circular hole 8.By being provided with securing member on circular hole so that the uniform force of cutter shaft, meet dynamically balanced requirement.
In this utility model, power is rotated by drive system 3 band movable arbor 2, and straw is pulverized by the cutting blade 4 on cutter shaft 2, and meanwhile, the straw after pulverizing is subject to longitudinally disposed aerofoil 6, is outwards shed by straw.Layout due to aerofoil 6 helically track so that shedding of the straw after pulverizing is more uniform, throws speed also faster.
