Abstract
The utility model discloses a kind of grass breaking devices of mowing grass chopper, including the hammer cutter shaft, arc-shaped material retaining hood, the stationary knife for being arranged on material retaining hood and matching with hammer edge being made of several hinged hammer knives；The material retaining hood semi-surrounding is on hammer cutter shaft top；Stationary knife is located at hammer cutter shaft back side top.Using the technical solution of the utility model, by the way that the shaft for being hinged with hammer knife, the stationary knife to match with hammer knife is arranged, it is used cooperatively using hammer knife with stationary knife, the weeds after cutting off carry out secondary chopping, can prevent longer weeds from mutually winding, and blade is stuck.
Description
Technical field
The utility model relates to grass trimmer fields, and in particular to a kind of grass breaking device of mowing grass chopper.
Background technique
With the development of modern agriculture, miniature grass trimmer using very universal, since its is small in size, using flexible,
Convenient, walk-behind greensmower has obtained the favor of user.
Existing walk-behind greensmower includes cylinder lawnmower and rotating disc type grass trimmer, and cylinder lawnmower is generally equipped with
1~4 vertical type cylinder shape arranged side by side or scroll drum.Roller is by adhesive tape or Bevel Gear Transmission, adjacent two rollers relative rotation,
The weeds cut off are under the pulling over of a pair of of roller, and laying is at neat small swath backward.It is able to satisfy close mowing requirement, but structure is inadequate
It is compact.Horizontal cutterhead is provided on rotating disc type grass trimmer, for cutterhead generally by gear drive, the steering of adjacent cutterhead is opposite.Knot
Structure is compact, stable drive, reliable.
But the form of a blade of existing grass trimmer is more single, the weeds longer dimension after being cut off, between weeds mutually
Winding, it is easy that blade is stuck, and larger-size weeds decomposition rate is slower, is unfavorable for go back to field.
Utility model content
To solve the problems, such as that the weeds after cutting off mutually wind, and blade is stuck, it is broken that the utility model provides a kind of mowing
The grass breaking device of careless machine is cooperated by the way that the shaft for being hinged with hammer knife, the stationary knife to match with hammer knife is arranged using hammer knife and stationary knife
It uses, the weeds after cutting off carry out secondary chopping, can prevent longer weeds from mutually winding, and blade is stuck.
The technical solution of the utility model is as follows:
A kind of grass breaking device of mowing grass chopper, including the hammer cutter shaft, arc-shaped gear being made of several hinged hammer knives
Material cover, the stationary knife for being arranged on material retaining hood and matching with hammer edge；The material retaining hood semi-surrounding is on hammer cutter shaft top；Stationary knife
Positioned at hammer cutter shaft back side top.
The technical principle of the utility model is, during shaft rotation, the hammer knife in shaft first cuts off weeds, cuts
The weeds having no progeny enter between shaft and material retaining hood with hammer knife；Shaping is carried out to weeds, so that weeds is flocked together, then
Weeds, by being cooperated at stationary knife by stationary knife and shaft, carry out secondary chopping, Neng Goufang to weeds under the drive of hammer knife
Only longer weeds mutually wind, and blade is stuck；And the weeds after shredding are decomposed comparatively fast, and field is conducive to go back to.
Preferably, it is the strip blade of angle steel shape that the stationary knife, which has cross section,；Blade is fixed on the backgauge on one side
On cover；Another side is equipped with jagged blade；Blade is towards the hammer cutter shaft.Convenient for the dismounting and maintenance of stationary knife.
Preferably, the blade is arranged on blade；The strip-shaped hole perpendicular with blade is offered on blade；Blade passes through
Bolt is fixed on the blade.It is detachable between blade and knife plate, it is conveniently replaceable after edge wear；And knife can be adjusted
Sword stretches out the distance of blade, meets different chopping demands.
Preferably, the material retaining hood is equipped with side baffle；Side baffle is mounted on the both ends of hammer cutter shaft.It can prevent weeds four
It splashes at place.
Preferably, the blade both ends of the setting blade are equipped with positioning protrusion, and positioning protrusion, which is connected on side baffle, to be determined
In the hole of position.Stationary knife is supported by side baffle, the deformation velocity of stationary knife can be slowed down, extend the service life of stationary knife.
The beneficial effects of the utility model are that can prevent longer weeds from mutually winding, and blade is stuck；Weeds can
Fast decoupled；Be conducive to go back to field；And stationary knife convenient for disassembly and assembly, easy access, long service life.
