Abstract
The utility model discloses a kind of combining machine-cut grass arranging devices, including shell, cutting blade and moving knife bobbin, one end of the moving knife bobbin is equipped with belt pulley, saw blade is equipped with below cutting blade, the saw blade is mutually staggered with cutting blade, and cutting blade stretches between adjacent saw blade, and the saw blade is equidistantly fixed on saw blade axis, the both ends of saw blade axis are rotatablely connected with shell, the axis parallel of the axial line and moving knife bobbin of saw blade axis；With one end of belt pulley homonymy stretching shell and equipped with gear two is additionally provided on gear one, with the shell of belt pulley homonymy on saw blade axis, the gear two is fixed on the shell by shaft, and the shaft is connect with belt pulley co-rotating transmission；The gear ratio of two engaged transmission of gear one and gear, belt pulley and gear one is 19 ~ 30:1.On the contrary, saw blade rotation is slow, holding optimum speed is poor between cutting blade, best to stalk cutting effect for the direction of rotation of the utility model moving knife bobbin and saw blade axis.
Description
Technical field
The utility model is related to farm machineries, more particularly to combine harvester component.
Background technology
With social development, mechanization of agriculture is more and more universal, in crop harvestings such as wheat, rice, substantially in fact
Existing combine operation.In order to improve the utilization rate of wheat rice straw, avoid the fire hazard brought by crop straw burning, by
Straw millstone is configured on combine harvester, and the stalk exported from combine harvester is crushed, agriculture is then shed
In field, straw-returning is realized.Existing straw millstone be threshing chamber straw outlet setting cut grass arranging device, pass through spiral shell
Stalk after threshing is transported to by rotation conveying cuts grass arranging device, by being shed into farmland after cutting grass arranging device chopping.
Grass arranging device in the prior art of cutting generally includes cutting blade and ledger-plate, by the two relative motion straw powder
It is broken.But such " crushing " is equivalent to " pulling apart " actually, reason is then that the cutting edge of high-speed rotating cutting blade is fragile, is being used
The very short time will rust, so its cutting power substantially reduces.Occur ledger-plate being improved to later in the prior art
The technology of saw blade, but cut that Lysimachia sikokiana effect is still undesirable, and many stalks can be overstock is cutting in grass arranging device.This is because existing
There is the saw blade in technology identical as the rotation direction of cutting blade, the rotation of the two can not so that stalk is effectively shredded,
It has instead and does not have largely stalk chopped to be overstock under the collective effect of the sawtooth of saw blade and cutting blade to cut grass arranging device
Straw outlet, or even be wrapped on saw blade, generate failure.
Utility model content
In order to overcome drawbacks described above, the utility model provides a kind of combining machine-cut grass arranging device, saw blade and dynamic
The rotation direction of blade is on the contrary, cutting blade is big relative to the rotating ratio of saw blade so that crushing effect is protected, and cutting blade makes
Use longer life expectancy.
The utility model is achieved through the following technical solutions：
Combining machine-cut grass arranging device, including shell, cutting blade and moving knife bobbin, one end of the moving knife bobbin are set
There is belt pulley, is equipped with saw blade below cutting blade, the saw blade is mutually staggered with cutting blade, and cutting blade stretches into adjacent annular saw
Between piece, the saw blade is equidistantly fixed on saw blade axis, and both ends and the shell of saw blade axis are rotatablely connected, the axial line of saw blade axis
With the axis parallel of moving knife bobbin；Shell is stretched out with one end of belt pulley homonymy on saw blade axis and be equipped with gear one, with belt
It takes turns and is additionally provided with gear two on the shell of homonymy, the gear two is fixed on the shell by shaft, the gear two and belt pulley
Co-rotating transmission connects；The rotating ratio of two engaged transmission of gear one and gear, belt pulley and gear one is 19 ~ 30: 1.
It is additionally provided with drive pulley positioned at the outside of gear two in the shaft, the drive pulley passes through belt with belt pulley
Co-rotating transmission connects.
The saw blade axis is set to immediately below moving knife bobbin.
The rotating ratio of belt pulley and gear one is 20: 1.
The beneficial effects of the utility model：
One, the direction of rotation of the utility model moving knife bobbin and saw blade axis is on the contrary, dynamic between moving knife bobbin and saw blade axis
Power is driven by drive pulley and intermeshing gear one, gear two, and the rotating ratio of belt pulley and gear one is 19 ~ 30:1,
The rotating speed of saw blade on saw blade axis is very slow compared with the rotating speed of cutting blade, keeps optimum speed poor between the two, is cut to stalk
It is best to cut effect.
Two, therefore the rotation direction of the saw blade of the utility model and the rotation direction of cutting blade are on the contrary, be conducive to cut
Grass arranging device is cut in broken stalk submitting.

Specific implementation mode
As described in Figure 1, the utility model includes shell 1, cutting blade 2 and moving knife bobbin 3, and the one of the moving knife bobbin 3
End is equipped with belt pulley 4, and 2 lower section of cutting blade is equipped with saw blade 5, and the saw blade 5 is mutually staggered with cutting blade 2, and cutting blade 2 stretches into
Between adjacent saw blade 5, the saw blade 5 is equidistantly fixed on saw blade axis 6, and both ends and the rotation of shell 1 of saw blade axis 6 connect
It connects, the axis parallel of the axial line and moving knife bobbin 3 of saw blade axis 6.
As shown in figure 3, in the present embodiment, the saw blade axis 6 is set to immediately below moving knife bobbin 3.
As shown in Figures 2 and 3, shell 1 is stretched out with one end of 4 homonymy of belt pulley and be equipped with gear 1, tooth on saw blade axis 6
1 are taken turns to rotate coaxially with saw blade axis 6.
It is additionally provided with gear 28 on the shell 1 of 4 homonymy of belt pulley, the gear 28 is fixed on shell 1 by shaft 9
On, the shaft 9 is connect with 4 co-rotating transmission of belt pulley.
As shown in figure 4, in the present embodiment, the outside in the shaft 9 positioned at gear 28 is additionally provided with drive pulley 10,
Drive pulley 10 is rotated coaxially with gear 28.The drive pulley 10 is connect with belt pulley 4 by belt co-rotating transmission.
28 engaged transmission of gear 1 and gear, the rotating ratio between belt pulley 4 and gear 1 is 19 ~ 30: 1.
Optimal, the rotating ratio of belt pulley and gear one is 20:1, the chaffcutter effect for cutting grass arranging device at this time is best.
