Description

A kind of intelligent grass-removing cutter head structure

Technical field

The utility model relates to a kind of mower, relates in particular to that a kind of efficiency of mowing is high, low in energy consumption, the intelligent grass-removing cutter head structure of lawn care natural beauty.

Background technology

Existing mower cutterhead and blade are metalwork, blade wherein is generally on the edge that cruciform shape is fixed on cutterhead, again by the blade High Rotation Speed on driven by motor cutterhead and cutterhead, and cut off weeds to realize the object on finishing lawn by blade, when use because blade is perpendicular cuts, therefore while there is mower cutting, resistance is large, energy consumption is high, the problems such as blade frangibility, and because the top, lawn after cutting is neat hairbrush shape, lack the aesthetic feeling under self-sow state, therefore lawn landscaping effect is poor.

Chinese patent discloses a kind of hand-held electric motor mower quotation (CN2781743Y), this cutterhead is made up of disk body, blade and torsion spring, described disk body centre bore is connected with the output shaft of mower, disc surfaces is along the circumferential direction distributed with blade shaft, the end of described blade is hinged on disk body by blade shaft, its blade launches to surrounding, described torsion spring set be located on blade shaft and act on blade and disk body between, restriction freely the rotating of blade.This device reduces the impulsive force of blade by sheathed torsion spring on blade shaft, but the blade in this device is also perpendicular cuts, therefore when same existence is cut, blade resistance is large, energy consumption is high, blade frangibility, and top, lawn after cutting is neat hairbrush shape, lack the aesthetic feeling under self-sow state, the technical problem of the poor grade of lawn landscaping effect.

Summary of the invention

The utility model has mainly been to provide a kind of simple in structure, when cutting, blade resistance is little, mowing efficiency is high, energy consumption is low, blade long service life, and the intelligent grass-removing cutter head structure of lawn care natural beauty, while having solved the cutting existing in prior art, blade resistance is large, energy consumption is high, blade frangibility, and lawn after cutting lacks the aesthetic feeling under self-sow state, the technical problem of the poor grade of lawn landscaping effect.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of intelligent grass-removing cutter head structure, comprise and on circular disk body and disk body, extend to several blades outside disk body, middle part at disk body is provided with locating hole, the outside integral type in edge of described disk body extends to form annular insert retention disk, in insert retention disk, be provided with several blade locating slots, between the median plane of blade locating slot and corresponding disk body axial centre face, be provided with angle, blade is fixed in blade locating slot.Blade locating slot is provided with angle with corresponding disk body axial centre face, be blade in insert retention disk to a direction slant setting, not only increase thus the location area of blade, blade can be firmly fixed in insert retention disk, improve the rigidity of blade, extend the service life of blade, and in cutting process due to blade of grass on blade sliding distance increase, therefore good cutting effect, mowing efficiency is high, lawn care natural beauty, and Cutting Drag is little simultaneously, energy consumption is low, and overall structure is simple.

As preferably, described blade locating slot tilts in the same way in insert retention disk, and the median plane of blade locating slot is 20 ゜ to 40 ゜ with the angle between corresponding disk body axial centre face, and the blade of blade is in oblique outside is fixed on blade locating slot.When blade is obliquely installed in the same way on the edge of insert retention disk, the each blade cuts resistance of cutting process is consistent, has both ensured the stability in use of mower, makes again lawn care natural beauty; Reasonably blade inclination angle, can make blade reasonable stress, further extends the service life of blade.

As more preferably, the blade of described blade parallels with cylindrical tangent line corresponding on disk body.In the time that blade parallels with cylindrical tangent line corresponding on disk body, in cutting process, blade of grass can carry over the cutting of sliding from inside to outside of blade direction, mowing maximizing efficiency, and ensured cutting effect.

As preferably, described insert retention disk is towards oliquely downward extending on the edge of disk body, and the angle of the horizontal surface of insert retention disk and disk body is 3 ° to 13 °.The impulsive force of blade when blade keeps rational inclination angle to reduce to cut, reduces energy consumption, makes to reach natural aesthetic feeling after lawn care.

Can be on the edge of disk body uniform multiple insert retention disk be set, as preferably, on the edge of described disk body, be laid with four insert retention disk.By four insert retention disk are set on the edge of disk body, and four insert retention disk are on the edge that cruciform shape is symmetrically distributed in disk body, can cut in turn by four blades, leak careless probability thereby reduce, improve mowing cleanliness and cutting effect, four blades are beneficial to disk body maintenance dynamic equilibrium simultaneously, improve the stability of mower operation.

Blade locating slot can be arranged on the end face of insert retention disk, and as preferably, described blade locating slot is arranged on the bottom surface of insert retention disk.When blade locating slot is positioned at the bottom surface of blade location-plate, be convenient to blade dismounting.

As preferably, on the insert retention disk surface relative with described blade locating slot, be provided with welded nut, blade is fixed on blade locating slot bottom by screw horizontal-clamping.Blade fixed form is simple and reliable.

As preferably, described disk body is made up of nylon material.Nylon material is lightweight, and intensity is high, can reduce the power consumption of mowing system, improves energy utilization rate, realizes energy-saving and emission-reduction object.

Therefore, a kind of intelligent grass-removing cutter head structure of the present utility model has following advantage:

1, blade tilts to be fixed in insert retention disk in the same way, not only increase the location area of blade, improve the rigidity of blade, Cutting Drag is little simultaneously, extends the service life of blade, and has increased cutting process blade of grass sliding distance on blade, good cutting effect, efficiency is high, and energy consumption is low, lawn care natural beauty;

2, blade and level mowing plane are low-angle folder degree, realize mowing maximizing efficiency, and power consumption is lower, more natural beauty of mowing effect;

3, blade is crossing distribution, can cut in turn, leaks careless probability thereby reduce, and improves mowing cleanliness, realizes better cutting effect;

4, adopt the cutterhead of the nylon material that lightweight intensity is high, combine with short and thin manganese vanadium steel blade, make whole cutter head structure lightweight, reduced mowing system power dissipation, improve energy utilization rate, realize energy-saving and emission-reduction object.
