Abstract

The invention discloses a cutting blade which comprises a blade matrix, cutting edges and sliders. The blade matrix is provide with slide rails, the cutting edges are mounted on the blade matrix, the sliders can move on the slide rails, a groove is formed in the middle of each slider and comprises a bottom wall and a pair of side walls on two sides of the bottom wall, a grinding part is arranged on at least one side wall of each groove, and the cutting edges are clamped in the grooves. The cutting blade has the advantage that the cutting edges can be automatically ground when the sliders slide and accordingly can keep sharp.

Description

Cutting blade
Technical field
The present invention relates to a kind of cutting blade.
Background technology
A kind of cutting blade used on mower that is installed on, after repeatedly using, the cutter sector-meeting is worn and torn gradually.
On the basis that prior art has been carried out concentrating on studies, the inventor provides a kind of cutting blade of automatic grinding.
Summary of the invention
The purpose of the invention is: the cutting blade that a kind of automatic grinding is provided.
For achieving the above object, the invention provides a kind of cutting blade, comprise the blade base that is provided with slide rail, be installed on the cutting edge on blade base, described cutting blade also comprises the slide block that can move on slide rail, be provided with groove in the middle of described slide block, described groove comprises the pair of sidewalls of diapire and diapire both sides, and at least one sidewall is provided with abrasive article, and described cutting edge is fastened in groove.
Compared with prior art, the present invention at least has following beneficial effect:
Can the automatic grinding cutting edge when slide block slides, make cutting edge keep sharp state.
The accompanying drawing explanation
Fig. 1 is the structural representation of cutting blade of the present invention.
Fig. 2 is the cutaway view of cutting blade of the present invention
Embodiment
As depicted in figs. 1 and 2, a kind of cutting blade 1, comprise the blade base 11 that is provided with slide rail 10, be installed on the cutting edge 12 on blade base 11, also comprises the slide block 13 that can move on slide rail 10.
Cutting blade 1 is provided with installing hole 111 for fixedly mounting with driver part.At least one side of installing hole 111 is provided with above-mentioned blade base 11.The present invention is preferred, and installing hole 111 both sides are equipped with blade base 11.
Blade base 11 is provided with slide rail 10.Preferably, also be provided with limited block 112 on blade base 11.
Cutting edge 12 is for cutting lawns.Cutting edge 12 can be that blade base 11 directly puts the first edge on a knife or a pair of scissors, and can be also the separate part that split arranges.The cutting edge 12 of split setting is fixed on blade base 11 by mechanical docked mode such as welding or clampings.
Be provided with groove 131 in the middle of slide block 13.Cutting edge 12 is fastened in groove 131.Groove 131 comprises diapire and the pair of sidewalls be connected with diapire.At least one sidewall and cutting edge 12 interference fit.During cutting blade 1 rotation, cutting blade 1 when starting rotation or stopping the rotation because the variation of centrifugal force is slided on slide rail 10.When sliding, the grass bits that adhere on cutting edge 12 can be wiped off slide block 13.Therefore, what during cutting edge 12 work, the grass juice factor of contact can be very fast is air-dry, is not easy to occur corrosion.Preferably, at least one sidewall is provided with abrasive article, and when slide block 13 slides, abrasive article can automatically grind and make cutting edge 12 keep sharp state cutting edge 12.
Preferably, smooth in order to make slide block 13 slide, be connected with the elastic reset part between blade base 11 and slide block 13.This elastic reset part is generally spring.
Preferably, slide block 13 is provided with receiving space and passage.At least one sidewall of passage conducting receiving space and groove 131.Accommodate lubricant in receiving space.Lubricant is generally lubricating oil.Lubricating oil and water are immiscible, therefore can stop grass juice factor to touch cutting edge 12, have better anti-corrosion effect.
Preferably, accommodate grinding agent in receiving space.Can when slide block 13 slides, be ground cutting edge 12 simultaneously, make cutting edge 12 keep sharp.

Claims (6)
