Abstract
The utility model discloses a turnover and reversing arrangement used for a rotary cultivator. The utility model is composed of a central transmission case body (7) and a supporting shaft sleeve (2) connected with the case body, wherein, a half shaft (1) and a through shaft (6) are vertically supported in the central transmission case body (7), and a bevel gear pair which is composed of a bevel gear (3) and a bevel gear (9) is respectively installed on the half shaft and the through shaft; the through shaft (6) has a symmetrical structure corresponding to the shaft line of the half shaft, in order to realize integral turnover or the replacement and the installation of the bevel gears; therefore, the purpose of reversing a rotary cultivation shaft is realized. The utility model not only can conveniently realize positive rotation, contrarotation and reversing operation, but also has the advantages of simple structure and easy fabrication and installation.
Description
The utility model belongs to a kind of agricultural tillage machine tool, relates in particular to the improvement of rotovator actuating unit.
Rotovator is present widely used agricultural driving tillage machinery, and can be divided into by the rotation direction of its rotovator rotary tillage shaft is just changeing rotovator and counter-rotating rotovator two big classes.Just change the deficiency that rotovator has solved cultivation operation with tractor uses, realized soil turn over and fragmentation is carried out simultaneously; The counter-rotating rotovator is on the basis of just changeing rotovator its rotary tillage shaft to be transformed into reverse rotation, to reach stubble-cleaning, to bury blue or green purpose.Though this two big class rotovator differs from one another, they all exist function singleness, and the rotation direction of rotovator can't conversion, can not have both turn over hack and stubble-cleaning and bury blue or green these two kinds of requisite farmland elemental operations.Chinese patent application 96246058.3 discloses a kind of rotovator rotating device, and it is made up of bevel gear group and double sided clutch etc., stirs the purpose that clutch reaches commutation by shift fork.But this apparatus structure complexity, always there is a bevel gear to be in idling conditions and to increase power consumption in the course of work, double sided clutch on the clutch shaft is subject to responsive to axial force and forms play, particularly concerning the rotovator rotary tillage shaft of often not changing rotation direction, adopt clutch, fork structure to seem more complicated, loaded down with trivial details.
The purpose of this utility model will provide a kind of structure more simple exactly, and the reversing arrangement easily of operating, commutate makes the positive and negative rotation direction of rotary tillage function according to operation needs conversion rotovator.
In order to achieve the above object, the technical scheme that the utility model adopted is: in rotovator central authorities transmission case, vertical support semiaxis and two rotating shafts of axis, being installed on two bevel gears on semiaxis and the axis is meshing with each other and constitutes the bevel gear pair, its axis has symmetrical structure for the semiaxis axis, promptly this axis both can be partly symmetrical for the semiaxis axis, also can be all symmetrical, like this when this central authorities' transmission case installs to the axis other end with symmetrical structure around 180 ° of installations of semiaxis axis upset or with the accent of the bevel gear on the axis, the relative rotation direction conversion of two bevel gears that are meshed, thus reach the purpose that conversion rotovator rotary tillage shaft commutates.
After adopting this structure, because the axis that is supported on the casing has symmetrical structure, under the situation that does not change the power shaft rotation direction, by the upset of casing or the accent dress of bevel gear position, just can change turning to of rotary tillage shaft, and need not on axis, to install clutch and bevel gear group, it is simple in structure, compact, action accurately for the rotovator of often not changing rotation direction, seems particularly convenient, reliable; Again since whole device drive path rationally, part economizes, have make easy to maintenance, the advantage that fault rate is low, the life-span is long.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of an embodiment of the upset reversing arrangement of the utility model rotovator;
Fig. 2 is the structural representation of structure shown in Figure 1 around 180 ° of semiaxis axis upsets;
Fig. 3 is the structural representation of another embodiment of the utility model rotovator upset reversing arrangement;
Fig. 4 is the structural representation of structure shown in Figure 3 around 180 ° of semiaxis axis upsets.
Shown in Figure 1, on central transmission case body 7, pass through garden taper roller bearing 4, be vertically installed with semiaxis 1 and axis 6, axis 6 is a power input shaft, semiaxis 1 is a power take-off, axis 6 has axle head external splines, bearing guard and the bevel gear shelves of symmetry for the semiaxis axis, the internal spline of universal joint 5 matches with the external splines of axis 6, with transferring power, the bevel gear pair that is made of bevel gear 3 and bevel gear 9 is installed on semiaxis 1 and the axis 6, and central transmission case body 7 links by supporting sleeve 2 and rotary tillage frame.When axis 6 clockwise directions rotated, semiaxis 1 also was output clockwise.The axle head of axis 6 adopts the spline structure of symmetry, can install the conversion rotation direction by the casing upset easily; And symmetrical fully axis structure both can have been installed by upset, can come the conversion rotation direction by transferring the bevel gear of adorning on the axis again.Fig. 2 installs or bevel gear 9 is transferred the installation site figure of the other end that is loaded on axis 6 around the upset of semiaxis axis for whole box body shown in Figure 1, and axis 6 still be to drive clockwise, and 1 of semiaxis be counterclockwise output.Sealing ring 8 is loaded between the end face of casing 7 and supporting sleeve 2, to prevent the seepage of lubricating oil in the casing.
Shown in Figure 3, semiaxis 1 is a power input shaft, axis 6 is connected with power take-off 11, axis 6 has axle head half a coupler, bearing guard and the bevel gear shelves of symmetry for the semiaxis axis, power take-off 11 links by shaft coupling 10 with axis 6, shaft coupling adopts positive coupling, also can adopt the shaft coupling of other corresponding constructions certainly.The internal spline of universal joint 5 matches with the external splines of semiaxis 1 end, with transferring power.The bevel gear pair that is made of bevel gear 3 and bevel gear 9 is installed on semiaxis 1 and the axis 6, and central transmission case body 7 links by axle sleeve 2 and rotary tillage frame, and when semiaxis 1 clockwise direction rotated, axis 6 is output clockwise also.Fig. 4 transfers the installation site figure that is loaded on axis 6 other ends for complete machine shown in Figure 3 around 180 ° of installations of semiaxis axis upset or with bevel gear 9, and semiaxis 1 still is the clockwise direction rotation, and 6 of axises are output counterclockwise.
