Description
Technical field
The utility model relates to the steering mechanism of structure, particularly puncher of puncher of the punching ventilation of lawn maintenance, belongs to the lawn maintenance field of mechanical technique.
Background technology
Existing lawn puncher is made up of body, engine, transmission mechanism, front component, wheel assembly, crane arm etc., and puncher is by 4 supports.The transmission mechanism that constitutes by the sprocket wheel chain that is movably walking drives front component, and rearmounted punching cutterhead lifts liftoff.The punching cutterhead falls during punching work, front-wheel drive walking, cutterhead rotation punching.Existing puncher can not be turned while punch because 4 supports, can only directly walk, and reverse end for end necessary pull-up crane arm, lifts the punching cutterhead, firmly presses down handgrip then, and the front-wheel perk just can be turned to, and operates heavy extremely inconvenience; Want the perk front-wheel because turn, the weight of machine rolls on the lawn when turning to and destroys the lawn all on trailing wheel; The weight of lawn puncher can not be too heavy, and overweight turning is difficulty just relatively, in order to overcome in the market light partially of this shortcoming with the line puncher, and the performance deficiency that brings thus, the punching degree of depth does not generally reach the requirement of ventilation maintenance.
The utility model content
The purpose of this utility model is exactly the deficiency that will overcome existing puncher, provides a kind of turning easy to operate, the lawn puncher that drilling quality is good.
The purpose of this utility model realizes by the improvement to existing puncher, novel lawn puncher, comprise engine, cutter head assembly, transmission mechanism, wheel assembly, the crane arm installed on body and the body, universal wheel is installed in the front portion that it is characterized in that body, between cutter head assembly and the cutter axis, be respectively equipped with isolator between wheel assembly and the wheel shaft, engine connects by transmission mechanism and drives wheel assembly.Described universal wheel is by comprising that axis, bearing, thrust bearing, spike, trunnion axis, wheel form.Isolator between described cutter head assembly and the cutter axis is made of feather key and isolator spline housing, feather key is installed on the cutter axis, the isolator spline housing is installed in the cutterhead axis hole, evenly be provided with three first quarter moon tooth breach on the inner hole wall of isolator spline housing, the outer circle wall of isolator spline housing is provided with the groove that is used for fixing.Isolator between wheel assembly and the wheel shaft is made of feather key and isolator spline housing, feather key is installed on the wheel shaft, the isolator spline housing is installed in the axle hole, evenly be provided with three first quarter moon tooth breach on the inner hole wall of isolator spline housing, the outer circle wall of isolator spline housing is provided with the boss that is used for fixing.Being provided with isolator between described cutter head assembly and the cutter axis, is between the cutterhead of the central. set cutterhead both sides of cutter head assembly and cutter axis isolator to be installed.When the power that is transmitted by chain sprocket when cutter axis drove and makes inhour and rotate, feather key ordered about the isolator spline housing and rotates and drive cutter head assembly (having 5 groups of cutterheads) rotation with cutter axis, the cutterhead punching of fixing a cutting tool.When puncher was turned, cutter axis was around the rotation of one end, and the center of circle is on the left side or the right side of cutter head assembly, the rotating speed that surpasses cutter axis away from the rotating speed of the punching cutterhead in the center of circle, form feather key and slide, and become cutter head assembly and cutter axis slip, puncher is turned rapidly on the inclined-plane of first quarter moon tooth breach.
The utility model is rational in infrastructure simple, manufactures easily, and the front-wheel of puncher adopts universal wheel, use rear wheel drive instead, cutter head assembly is connected with cutter axis and wheel assembly connects with wheel shaft and adopts isolator, use easy to operate, it is convenient that punching and walking are turned, and drilling quality is good.
When the puncher punching moved ahead, cutter axis was driven by sprocket wheel, chain power transmission, and the feather key that is contained on the cutter axis drives rotation together by axle, and the interplanting of isolator spline is rotated counterclockwise, cutter head assembly rotation punching.When need turn to, be higher than cutter axis away from the cutterhead rotating speed of center of circle end, the feather key of isolator is under the effect on isolator spline housing inclined-plane, and feather key is slippage in cutter axis, and just isolator and cutter axis skid, thereby turn to purpose freely about reaching.
Puncher does not punch when moving ahead, wheel shaft is driven by sprocket wheel, chain power transmission, the feather key that is contained on the wheel shaft drives rotation together by axle, driving isolator spline interplanting by wheel shaft by feather key by the effect by the isolator spline housing is rotated counterclockwise, wheel speed apart from center of circle far-end when need turn to is higher than wheel shaft, under the effect on isolator spline housing inclined-plane, feather key is slippage in wheel shaft like this, thereby the isolator in the wheel and axle skid and turn to freely purpose about reaching.
