Description
Technical field
The present invention relates to grass dressing machine technical fields, and in particular to a kind of detent mechanism that realizing blade assembly fast assembling-disassembling,
Assembly and disassembly methods and grass dressing machine.
Background technology
Lawn growth for a period of time after, the blade of grass of a part of bottom is covered by the blade of grass on top, because without participate in it is photosynthetic
Effect, easily withers, can go mouldy for a long time rotten, and a portion becomes organic fertilizer, and part meeting mould growth causes
Entire lawn is withered, at this moment cannot solve the problems, such as this if only sprinkling drug, should timely comb out withered grass.Lawn grass dressing machine is
A kind of trimming machinery, movable blades effectively remove litter layer under the action of mechanical centrifugal power, enhance the disease resistance on lawn.
Lawn comb grass after can reduction shoot density appropriate, improve lawn aeration, promote lawn healthy growth.
Grass dressing machine is usually made of components such as blade assembly, driving wheel, motors, drives driving wheel operating to drive by motor
Blade assembly rotates, and realizes combing out for withered grass.Part grass is easily adhered but after grass dressing machine works long hours, on blade assembly
Bits need regular dismounting to get off cleaning, or long-time wear damage occurs using rear blade assembly, needs replacing new component,
At this moment it just needs to remove previous blade assembly.The blade assembly of existing grass dressing machine is directly anchored to by 2 screws
On grass dressing machine, need to exit 2 screws completely with special spanner when such as needing to change blade assembly, and screw need to be taken good care of, then
Blade assembly is installed other one.Whole process is comparatively laborious, and to prevent blade assembly from falling off, fixation spiral shell herein
It is larger to follow closely torsion, the problems such as thread fracture occurs in frequent easy disassembling, and dismounting is harder, prevents the screw removed from losing again
It loses, user's operation is more inconvenient.
Therefore, in view of problem above, it is necessary to propose a kind of mechanism of achievable blade assembly fast assembling-disassembling, be not necessarily to tool
Auxiliary dismounting simplifies dismounting step, facilitates the fast assembling-disassembling of blade assembly to replace, fixed without screw, avoid the occurrence of spiral shell
Loss problem is followed closely, disassembling operations are convenient, improve the comfort used the product by the user.
