Abstract

The utility model discloses a centrifugal mowing machine comprising a first rod body and a second rod body which is held by a user. The first rod body and the second rod body are movably connected with each other, a motor part internally provided with a motor is arranged below the first rod body, a tool bit is arranged at the tail end of the motor part, and a protective cover for preventing grass scraps from splashing is arranged above the tool bit. The blade comprises a first blade and a second blade, and vertical flanges are arranged on the edges of the first and second blades. According to the centrifugal mowing machine, the strength of the whole blade is improved greatly by virtue of the symmetrical first and second blades and the flanges arranged on the edges of the first and second blades, so that the blade is allowed to work at a high speed, and thus the grass scraps are effectively prevented from being accumulated on the blade.

Description

Centrifugal grass cutter

Technical field

The utility model relates to a kind of garden instrument, or rather, is a kind of centrifugal grass cutter.

Background technology

Existing grass cutter utilizes the blade of high speed rotating to realize mowing, because the insufficient strength of blade is usually stuck by the grass bits when causing blade under low speed, to rotate, even whole blade ruptures.

China's invention application 201010548632.3 discloses a kind of mower, comprising: housing; Be connected the motor on the housing, said motor has motor shaft; The blade that is used to mow, said blade is connected on the said motor shaft, and has at least one cutting edge; Power supplying apparatus, said power supplying apparatus are that motor provides energy when mower is worked, and rotate with a cutting speed thereby drive blade; Speed control unit selectablely is fixed at least one preset constant rotational speed with said cutting speed.The blade of this mower is still conventional design, and the obstruction of grass bits takes place easily.

201010261032.9 1 kinds of mower cutter sweeps of China's invention application disclose a kind of mower, comprise: a rotating speed output shaft; One blade; One is suitable for blade is clamped in the fast folder on the output shaft; Fast folder comprises: be suitable for being contained on the output shaft and lay respectively at the axle sleeve and the pressure head of blade both sides; Be provided with round table-like groove at axle sleeve towards an end of blade medial surface; Pressure head comprises one and can pass the blade installing hole and stretch into the torus of round table-like groove from the blade lateral surface, and first parts of tooth is positioned on the toric outer peripheral face; One is set to axle sleeve and applies the return mechanism towards the restoring force of blade medial surface; At least two joggle pieces, it is connected in output shaft and can be along moving perpendicular to the axial direction of output shaft, joggle piece has outer surface and towards inner surface, second parts of tooth be positioned on the inner surface of joggle piece and with the engagement of first parts of tooth.Equally, the blade of this mower is still conventional design, and the obstruction of grass bits takes place easily.

Summary of the invention

The utility model mainly is to solve the existing in prior technology technical problem, thereby provides a kind of grass bits that can effectively prevent to block the centrifugal grass cutter of cutter head.

The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:

A kind of centrifugal grass cutter; Comprise first body of rod and second body of rod that supplies the user to hand; Described first body of rod and described second body of rod are movably connected; The below of described first body of rod is provided with the motor section of establishing motor in, and the end of described motor section is provided with a cutter head, and described cutter head top is provided with one and prevents the over cap that the grass bits splash.

As the preferred embodiment of the utility model, described first body of rod is provided with first locating hole, and described second body of rod is provided with second locating hole that matches with described first locating hole, and described second locating hole is arranged on the inclined-plane.

As the preferred embodiment of the utility model, described cutter head comprises first blade and second blade, and described first blade and second blade are symmetricly set on the both sides of a rotating shaft.

As the preferred embodiment of the utility model, the edge of described first blade and second blade is equipped with a vertically disposed flanging.

Because the centrifugal grass cutter of the utility model utilizes symmetrically arranged first blade and second blade; With the flanging on the edge that is arranged on first blade and second blade; The intensity of whole blade can be provided greatly; Thereby allow blade work under at a high speed, effectively prevent the accumulation of grass bits on blade.
