Description
The utility model relates to employed device on a kind of tillage implement with the driving type rotary cultivating part, more specifically says so a kind ofly to plough on the machine cultivating apparatus under the employed middle driving box in the rotation of central driven type.
For a long time, both at home and abroad institute generally the rotovator of use mostly be the rotovator of side transmission, long and the complications of its drive path, complex structure, suspension centre-of gravity shift add that the rotovator working width widens year by year, have brought many unsurmountable shortcomings to side driving rotary cultivator.Since the seventies, the domestic and international rotovator that all begins one's study and use central transmission, but this rotovator all exists the problem of balking under the middle driving box.In the prior art, the way that addresses this problem mainly contains following three kinds: a kind of is to increase a movable cutter tooth device on rotovator, the structure of this device such as accompanying drawing 1, it is to draw an axle by middle driving box, an eccentric wheel 1 is installed on this axle, eccentric wheel 1 drivening rod 2, shifting lever 4 is shaken, and shifting lever 4 drives movable sleeve connecting rod 5, makes movable sleeve 6 move left and right, when eccentric wheel 1 off-centre is positioned at solstice, by the movable cutter tooth 7 farming lower box in a left side, when eccentric wheel 1 is positioned at solstice down, by the movable cutter tooth 3 farming lower box in the right side, the major defect of this device is that connecting portion is many, complex structure, easy to wear, transmission intensity is low.Second kind of way is a ploughshare to be installed come the farming lower box on middle driving box, and this is most popular a kind of both at home and abroad at present, but its shortcoming is easy especially extension grass and ploughs the back injustice.The third way is to come farming transmission case bottom by an oblique cutterhead is installed on rotovator, and shortcoming is that this cutterhead of tiltedly ploughing need come transferring power with an export-oriented joint, and the universal joint that exposes had both been hung grass easily, wearing and tearing easily again.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part and provides a kind of and can fit together with rotovator middle driving box and output shaft, grass not easy to hang, twines grass, not easy to wear, and cultivating apparatus under the high transmission case of transmission intensity.
For finishing above-mentioned purpose, the utility model provides cultivating apparatus under a kind of transmission case of central driven type rotovator, its special character is, this device has an inclination housing that can be installed on the middle driving box, cutterhead is tiltedly ploughed in one of installing in this housing, tiltedly plough to install on the cutterhead tiltedly to plough and revolve cutter, between inclination housing and tiltedly cultivated cutterhead, the bearing of tiltedly ploughing cutterhead in order to support is housed, described tiltedly ploughing in the cutterhead is provided with a spheroid, this spheroid can be installed on the output shaft of middle driving box, between the inwall of spheroid and tiltedly cultivated cutterhead, steel ball is housed, the part of this steel ball is positioned at the concave spherical surface on the spheroid, another part is positioned at vertical circular arc straight trough of tiltedly ploughing the cutterhead inwall, is provided with sealing device described tiltedly ploughing between cutterhead and the spheroid.
Promptly tiltedly cultivated cutterhead center line of said apparatus medium dip housing center line and output shaft axis are that the angle between the horizontal line can equal tiltedly to plough the angle between the vertical line that revolves cutter and tiltedly plough the cutterhead center line.Like this when tiltedly ploughing when revolving cutter and rotating to top, itself and output shaft axis are perpendicular, promptly are parallel to each other and can not influence each other with the rotary blade that is installed on the rotary ploughing cutter shaft.Learn that through test and calculating the farming effect is better when above-mentioned angle is between 11 °～13 °.
The accompanying drawing drawing is described as follows:
Fig. 1 is a kind of prior art constructions schematic diagram;
Fig. 2 is the structural representation of a preferred embodiment of the utility model.
Below with reference to accompanying drawing the utility model is further described below:
Prior art shown in Figure 1 had been done description in the specification third part.
Know referring to Fig. 2, this device has an inclination housing 11 that can be installed on the middle driving box power take-off lever bearing end cap 12, angle between this housing center line and power take-off 13 axis is 12 °, cutterhead 8 is tiltedly ploughed in one of installing in the inclination housing 11, the tiltedly cultivated cutter 9 that revolves is installed on the tiltedly cultivated cutterhead 8, tiltedly plough revolve cutter 9 and inclination housing 11 center lines that is tiltedly the angle between the vertical line of cultivated cutterhead 8 center lines also be 12 °, between inclination housing 11 and tiltedly cultivated cutterhead 8, be equipped with two in order to support the bearing 10 of tiltedly ploughing cutterhead 8, the outer end of two bearings 10 is provided with sealing device, described tiltedly ploughing in the cutterhead 8 is provided with a spheroid 16, this spheroid 16 can be installed on the output shaft 13 of middle driving box by internal spline, between the inwall of spheroid 16 and tiltedly cultivated cutterhead 8, be evenly equipped with 8 steel balls 15, the part of each steel ball is positioned at the concave spherical surface on the spheroid 16, another part is positioned at vertical straight trough 14 of tiltedly ploughing cutterhead 8 inwalls, the section of this straight trough is circular arc, spheroid 16 can be given transmission of power by steel ball 15 and tiltedly plough cutterhead 8 like this, and steel ball 15 also can vertically done longitudinal sliding motion and rolling in the straight trough 14, between described spheroid 16 and tiltedly cultivated cutterhead 8, be provided with sealing device 17, enter between the two to prevent earth.
During use cultivating apparatus under two identical transmission cases is installed in the middle driving box both sides of rotovator respectively, when rotovator is worked, output shaft 13 drives spheroid 16 and rotates, spheroid 16 drives by steel ball 15 and tiltedly ploughs cutterhead 8 rotations, because steel ball 15 can move in vertical straight trough 14 of tiltedly ploughing on cutterhead 8 inwalls, thereby tiltedly plough cutterhead 8 and can in inclination housing 11, do oblique rotation, revolve cutter 9 and turn to down solstice when tiltedly ploughing, its inclination angle will reach maximum 24 °, and extend into and carry out farming under the middle driving box, revolve cutter 9 and turn to solstice when tiltedly ploughing, the axis of itself and output shaft 13 is perpendicular, promptly parallel to each other with the rotary blade that is installed on the rotary ploughing cutter shaft.
The tiltedly cultivated cutter 9 that revolves also can be perpendicular with the center line of tiltedly ploughing cutterhead 8 in the foregoing description, 11 of inclination housings should have 24 ° of bigger inclination angles like this, to guarantee that the tiltedly cultivated cutter 9 that revolves is turning to solstice down, can tilt to fully and carry out farming under the central transmission case, must make when mounted simultaneously tiltedly to plough and revolve cutter 9 and stagger mutually in the axial direction, revolve cutter 8 and rotate to solstice and produce between the two and influence each other when tiltedly ploughing avoiding with the rotary blade that is installed on the rotary tillage shaft.
Can find out that in conjunction with above-described embodiment this implementation Novel photo has transmission intensity height to prior art, grass not easy to hang, twine grass, because transmission mechanism is sealed in the not easy to wear and advantages of simple structure and simple in inside.
