Abstract
A through shaft type rotary tiller capable of tilling thoroughly and making farmland flatting comprises an integral vehicle frame, a protection plate, a gear case, and a rotary tillage shaft assembly. The shaft through type rotary tiller is characterized in that a I level gear case consisting of an axial cone gear and an angle gear is positioned on the upper part of the vehicle frame and is connected with the power take-off shaft of a tractor, the output end of the angle gear is connected through a universal joint drive shaft with the lower part of a II level side gear case positioned at the side wall of the vehicle frame, the output end of the II level side gear case is connected with the end part of the rotary tillage shaft of the rotary tillage shaft assembly, the I level gear case is fixed in the center of the integral vehicle frame, the II level side gear case is fixed at the side of the vehicle frame, the upper part of the rotary tiller is provided with a protection plate, and the back part is provided with a high-pressure support plate. The utility model has characteristics that the rotary tiller is a through shaft type rotary tiller, rotary tillage can be performed all around within the tillage range, rotary tillage blind area caused by the lower part of a middle gear case of a rotary tiller having two rotary tillage shafts at the left side and the right side can be prevented by adopting the through shaft type rotary tiller which has characteristics of compact conformation, safety, reliability, complete rotary tillage, sufficient earth-breaking and farmland flatting.
Description
Technical field
The utility model belongs to the farm machinery technical field, specifically a kind of shaft type rotovator.
Background technology
Traditional middle driving rotary cultivator is middle driven type, and both the transmission case assembly was arranged on complete machine central authorities, about rotary tillage shaft then has two, is arranged in the left and right sides.In use there are a lot of problems in this structure.The one, because structure causes the middle driving box bottom to occupy 140 millimeters width rotary blade can not be installed, form the rotary tillage blind area, can't plough; The 2nd, for remedying the problems referred to above, share beak is installed in the middle driving box front lower place, be used for the immature soil of blind area is dug, but do not have the effect of rotary tillage; The 3rd, because the existence of blind area is revolved ground and is left one groove mark, soil out-of-flatness, impact effect afterwards.
Summary of the invention
The purpose of this utility model provide a kind of in the working width scope abundant, the smooth wholely shaft type rotovator of rotary tillage.
The purpose of this utility model is achieved in that it comprises the integral frame vehicle frame, protective plate, transmission case, the rotary tillage shaft assembly, it is characterized in that: be provided with the I level middle driving box that an axial cone tooth that is connected with tractor rear portion power take-off and bevel gear are formed on the top of integral frame vehicle frame, the output of this bevel gear links to each other with the II level side transmission case input that is arranged on integral frame vehicle frame sidewall by a Cardan shaft, and the output of this II level side transmission case is connected with the rotary tillage shaft end flange of axis rotary tillage shaft assembly.
The angle of the power shaft of I level middle driving box is horizontal versions or raises the dihedral formula that the angle of wherein raising the dihedral formula is the 10-15 degree.This is because the rear power output shaft of the large and middle tractor of new production is overhead highly more and more high, it is excessive to have influence on the Cardan shaft use angle that is connected with tractor, easily cause drive shafts fracture, raising angle 10-15 degree can make the power shaft angle lift, the power transmission shaft loading angle dwindles, guaranteed to use reliably, therefore unlikely fracture is specially adapted to the overhead higher large and middle tractor of power take-off.
Because I level middle driving box and side II level side transmission case in the middle of transmission case is divided into, can realize that rotary tillage shaft is a shaft type, in the working width scope, accomplish omnibearing rotary tillage during operation, two rotary tillage shaft rotary tillage blind areas that cause whole transmission case bottom in the centre about having overcome in the past, rotary tillage is more abundant after the operation, and the soil is more smooth.
In addition, the utility model also is useful for stubble-cleaning, rotary tillage combined soil preparing machine, can once finish four operations such as stubble-cleaning, rotary tillage, ridging, suppression.
Description of drawings
Fig. 1 is a side-looking structure diagram of the present utility model;
Fig. 2 is a transmission system schematic diagram of the present utility model.
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
Shown in Fig. 1-2,3 is the integral frame vehicle frame among the figure, 4 is protective plate, be provided with the I level middle driving box 1 that an axial cone tooth 8 that is connected with tractor rear portion power take-off and bevel gear wheel 9 are formed on the top of integral frame vehicle frame 3, the output of this bevel gear wheel links to each other with II level side transmission case 2 inputs that are arranged on integral frame vehicle frame 3 sidewalls by a Cardan shaft 7, and the output of this II level side transmission case 2 is connected with the rotary tillage shaft end flange of axis rotary tillage shaft assembly 6.The angle of the power shaft of above-mentioned I level middle driving box is for raising dihedral formula (as shown in Figure 1), and the angle of wherein raising the angle is 12 degree; Also be provided with at the rear portion of axis rotary tillage shaft assembly direction of advance and suppress supporting plate 5, this is suppressed supporting plate and is connected with integral frame vehicle frame rear sidewall.
By shown in Figure 2, I level transmission case 1 is made up of I axial cone tooth 8 and bevel gear wheel 9.It changes direction with the power of tractor input through slowing down, and by Cardan shaft 7, is sent to II level side transmission case 2 again; This II level side transmission case is by input splined shaft 10, driving gear 11, and idler gear 12, reduction gearing 13, driving shaft 14 are formed; Last power reaches shaft type rotary tillage shaft assembly 6.
Its operation principle is: the power (torque) from tractor slows down by I level transmission case 1, by Cardan shaft 7, drives to II level side transmission case 2 again, drives 6 rotations of shaft type rotary tillage shaft assembly.Integral frame vehicle frame 3 fixedly secures I level transmission case 1 in central authorities, is fixing II level side transmission case 2 at side.Suppress supporting plate 5 and not only the soil block that flies out after the rotary tillage further can be smashed refinement, and lean on the pressure of spring, with the soil compaction after the rotary tillage.Protection supporting plate 4 designs for preventing that soil from flying to spray.
