Abstract
The utility model discloses a connection structure of a knife shaft of a rotary cultivator and a power shaft, the connection structure adopts a structure which comprises the power shaft, a knife shaft and a connecting shaft sleeve, wherein, the connecting shaft sleeve is arranged between the power shaft and the knife shaft of the rotary cultivator, the end part of the power shaft is cone-shaped, a fastening screw is arranged at the shaft end, the connecting shaft sleeve adopts a cone-shaped hole, a connecting flange plate is arranged at the end part of the connecting shaft sleeve, the shaft sleeve is connected with the power shaft through the fastening screw and a fastening nut, and a flange plate is also arranged at the end part of the knife shaft of the rotary cultivator. The utility model has the advantages that the structure is reasonable, the clearance between the power shaft and the shaft sleeve is eliminated, the abrasion is greatly reduced, and the service life is prolonged, thereby saving maintenance and replacing cost.
Description
Technical field
This use is novel to relate to a kind of mechanical connecting structure, particularly relates to a kind of rotary tiller shaft and line shaft syndeton.
Background technology:
Mostly agricultural machinery is to drive the operation part by power section, connected mode therebetween is to determine according to the function of operation part, its rotovator is as operating farm tool, comprise a cutter shaft that rotary blade is installed, be male connection between this cutter shaft and the line shaft, be accustomed to by people for a long time, but in the long-term production operation, the inventor finds that existing male connection is column type, transmission of power is a spline shaft structure, because the agricultural machinery machining accuracy is not high, bigger in gap radially, continuous operation meeting accelerated wear test between axle and the axle sleeve, reduce the service life of machinery, often maintenance, change, can increase production cost, but do not have effective solution.
Summary of the invention:
The utility model is at the deficiencies in the prior art, a kind of rotary tiller shaft and line shaft syndeton are provided, can eliminate the gap between cutter shaft and the line shaft, reduce wearing and tearing, prolong its service life, technical problem to be solved is simple in structure, connect, easy accessibility, technical solution adopted in the utility model is as follows, the utility model comprises line shaft, cutter shaft and connecting bushing structure, it is characterized in that being provided with connecting bushing between line shaft and rotary tiller shaft, the line shaft end is taper, and axle head is established fastening screw, connecting bushing is a bellmouth, its end is provided with mounting flange, axle sleeve is connected with line shaft with nut by fastening screw, and the rotavator knife shaft end also is a flange.
This practicality, at first is installed in axle sleeve on the line shaft when installing and using novel, by flange cutter shaft is installed on the connecting bushing then.
Compared with prior art, the utility model is rational in infrastructure, has eliminated the gap between line shaft and the axle sleeve, greatly reduces wearing and tearing, has prolonged service life, thereby saves maintenance, renewal cost.
