Abstract
Two-side-driven rotary tillage soil-preparing machine, comprising transmission assembly and knife roller assembly, wherein the transmission assembly comprises an intermediate transmission box and left and right two side transmission boxes. A power input shaft and a differential connected to rear power output of the tractor through cardan joint are fixed in the intermediate transmission box, wherein a transmission gear is fixed on casing of differential and an input bevel pinion is mounted on the power input shaft, and the transmission gear and the bevel pinion transmit through gears. The differential has a structure that four orthogonal angle gears are fixed in the casing, wherein each of the two angle gears at left and right is connected with an output half shaft respectively of which outer end is connected to a drive gear in each of the two side transmission boxes respectively. When tooth spaces of gears in the left and right two side transmission boxes are not on a same line, the two angle gears at left and right in the differential would be lightly turned under the action of torque to make the drive gears in the two side transmission boxes normally work, thereby making knife roller assembly normally rotate. The soil-preparing machine has the advantages of gravity balance in whole body, fine stability and flat ground surface after ploughing.
Description
Technical field
The present invention relates to a kind of rotary tillage machinery, particularly a kind ofly collect rotary tillage, bury stubble, raking the soil level is the both-side driven rotary tillage soil-working machine of one.
Background technology
Utilize rotary tillage machinery is a kind of mature technology wholely, also is the machinery that generally use in national rural area.This machinery mainly is divided into middle housing transmission rotor and side casing transmission rotor two big classes.The characteristics of middle transmission are that the rotary tillage rotor is in middle driving box body both sides, balk for fear of the middle housing bottom, the spy has installed one little colter, and little colter can only staticly be ploughed, the ability of digging is so very easily cause the phenomenon that harmony soil stops up and balks below the middle housing.The side transmission is by being located at the transmission case transmission of rotor one side, and opposite side is contained on the side plate by bearing.Its great advantage is not have Yong Tuhe to balk in the middle of the rotor, and the flatness on whole ground is also better, and shortcoming is: the end that rotor is equipped with the side case is heavy, and the end that side plate is housed is light, and complete machine is heavy uneven, is skewed, so the tilt phenomenon of the ground level after the rotary tillage; Finish by a side case owing to drive the power of rotor, so the intensity of monolateral side case design must satisfy the needs of total load, module is bigger, and the large module gear glue performance is poor, and it is big to form noise, and impact is big, and the oil temperature is high, and part is fragile; Monolateral driving has strengthened the moment of torsion of rotor side plate end, and rotor is flexible and fracture.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of stable drive, complete machine weight balancing, the smooth both-side driven rotary tillage soil-working machine in back, arable land.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of both-side driven rotary tillage soil-working machine, comprise drive assembly and rotor assembly, be characterized in: drive assembly comprise middle driving box and about two side transmission cases, rotor assembly two ends with about transmission output gear in two side transmission cases join, be provided with power input shaft and a differential mechanism of being connected with the back power output of tractor by universal joint in the middle driving box, on the housing of differential mechanism, be fixed with travelling gear, the input bevel pinion is housed on the power input shaft, between above-mentioned travelling gear and the bevel pinion by gear drive, differential mechanism adopts the structure of four mutually perpendicular bevel gears is housed in its housing, two bevel gears are connected with the output semiaxis respectively wherein, output semiaxis the outer end respectively with two side transmission cases in initiative driver join.
The technical problem to be solved in the present invention can also come further to realize that the travelling gear on the differential casing is a bevel gear wheel by the following technical programs, bevel gear wheel directly with power input shaft on bevel pinion mesh.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, travelling gear on the differential casing is a horizontal gear, bevel pinion and the one bevel gear engagement on the axle of passing a bridge on the power input shaft, the axle of passing a bridge are provided with the transmission horizontal gear that cooperates with horizontal gear on the differential casing.
The technical problem to be solved in the present invention can also be come by the following technical programs further to realize, be provided with intermediate drive gear between initiative driver and the transmission output gear in the side transmission case.
When tractor motive power output shaft is rotated by the power input shaft that universal joint drives in the middle housing, then drive the big or small Bevel Gear Transmission of engagement, driving differential mechanism simultaneously rotates synchronously, the bevel gear of four mutual Vertical Meshing is housed in differential mechanism, and with the static rotation of differential mechanism, wherein two bevel gears drive separately join with it about the rotation of output semiaxis, the output semiaxis drives the both sides transmission that gear in two side transmission cases is realized the tool setting axle assembly again.
When about the teeth groove of two main drive gears in two side transmission cases during not at same straight line, if there is not the effect of differential mechanism, rotor will be interfered stuck because of left and right sides gear asynchronous.Differential mechanism has been arranged now, and this phenomenon just is eliminated.This be because: when differential mechanism rotate, the interference of left and right sides transmission case gear was eliminated in the interaction meeting of four bevel gears that differential mechanism is interior automatically.When the teeth groove of left and right sides transmission case gear during not at same straight line, its left and right sides semiaxis will obtain the opposite moment of torsion of active force, two bevel gears will be in next only clockwise little commentaries on classics of torsional interaction about in the differential mechanism, little commentaries on classics that another is counterclockwise, when little teeth groove that forwards the driving gear in the left and right sides transmission case at same straight line and fully during run-in synchronism, perpendicular to about two other bevel gears of two bevel gears will be stabilized in a position, make left and right sides driving gear operate as normal, thereby the cutter shaft assembly is normally rotated.
The present invention's advantage compared with prior art is: rotovator left and right sides transmission case body is equal in weight, the complete machine gravitational equilibrium, and good stability, it is smooth that the back is ploughed on the face of land; Because with same cutter shaft of two side transmission case gear drive, the load that every side transmission case gear is born is 1/2nd of a total load, so module can be less, meshing performance is good between gear and the gear, and noise is little, and the oil temperature is relatively low, machine vibration is little, and part is not fragile; Driving torque is distributed in the cutter shaft two ends, the moment of torsion equilibrium that cutter shaft bore, and cutter shaft is flexible and fracture.
