Abstract
The invention discloses blades for a mower, which are characterized by being formed through processing two or more materials. Blade edge parts at both sides on the blades at least contain an abrasion-proof engineering plastics material, and blade body parts at least contain an elastic engineering plastics material. Parts in direct contact with grass are made of engineering plastics with better abrasion resistance; the rest parts are made of engineering plastics with better elasticity; the entire blades are represented as elastic blades; and moreover, the blades for the mower have good abrasion resistance and long service life and are not easy to rupture. The service life of a single blade is increased, and the use cost is lowered; the performance-price ratio of a complete machine can be enhanced; and therefore, the market competitiveness of the complete machine is greatly enhanced, and the competitiveness of a product is enhanced.
Description
Technical field
The present invention relates to a kind of blade that is used on the electric tool, relate in particular to a kind of mower blade.
Background technology
Mower realizes that the form that grass is cut is generally two kinds, and a kind of is the nylon rope formula, and a kind of is the plastic knife chip.In use the failure mode of blade mainly contains two kinds, and is a kind of for rupturing, a kind of for wearing and tearing; After the former because blade of fracture was run into hard thing, the elasticity of itself was not enough, causes fracture; The former wearability because of blade of wearing and tearing is not enough, and very quick-wearing is serious in use.Blade material in the market seldom has a kind of material can satisfy the elasticity of blade and the demand of wearability simultaneously.Therefore, the service life of the mower blade that uses at present is all shorter, or when using serious wear or run into hard thing when beating the grass and rupture.
Summary of the invention
The blade that the objective of the invention is to solve electric tool especially blade service life of mower short, easy to wear and run into the hard thing problem of fracture easily when beating the grass.
For solving the problems of the technologies described above, the present invention provides a kind of mower blade, it is characterized in that; Materials processing by two or more forms; Wherein, the tough part of two side tools comprises wear-resisting engineering plastic materials at least on the blade, and the blade body part comprises the elastic engineering plastics material at least.
Said wear-resisting engineering plastic materials is to have among material PA6-GF50, PA6-GF30 or the POM (polyformaldehyde) of toughness and increasing tougheness one or more.The PA6 polyamide is commonly called as nylon, adds a certain proportion of glass fibre and increases its toughness.
Said elastic engineering plastics material is one or both among ABS (acrylonitrile-styrene-butadiene copolymer) or the PVC (polyvinyl chloride).
Said wear-resisting engineering plastic materials and said elastic engineering plastics material are through injection mo(u)lding.Realize new blade through processing repeatedly, with the elasticity that satisfies blade and the demand of wearability.
The blade portion that in use directly contacts with grass is divided into the strong engineering plastics of wearability; To solve the serious wear problem of blade in use; Remaining part is that elasticity good engineering plastics constitute, and shows as elastic blade to guarantee whole blade, when blade is run into hard thing, can realize strain; Avoid the fracture of the blade that two rigid shocks cause.
The beneficial effect that the present invention reached:
This blade is made up of two or more material, and the part that its characteristics are with grass directly contacts is wearability good engineering plastics; Remaining part is elasticity good engineering plastics; Whole blade shows as elastic blade, and wearability is good, easy fracture not, long service life.
Increase the service life of single blade, reduced use cost; Can improve the cost performance of complete machine; Thereby the market competitiveness of complete machine is significantly promoted, improved competitiveness of product.
Description of drawings
Fig. 1 is a blade sketch map of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1; The present invention is a kind of blade that is formed by two kinds of materials processings at least; Present embodiment is that example describes with the mower blade that two kinds of materials constitute; The tough part 1 of two side tools that directly contact with grass on the blade is the strong PA6-GF50 material of wearability, and blade body 2 parts are elasticity PVC material preferably.
Two kinds of material injection mo(u)ldings, making the blade general performance is elasticity blade preferably, can realize strain when running into hard thing when beating the grass, and avoids the fracture of the blade that rigid shock causes; Tough part 1 wearability of two side tools that directly contacts with grass simultaneously is better, and in the process of use, wearing and tearing slower increased service life of blade.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
Claims (4)
