Further, it as shown in Fig. 2, the side of upper cover plate 8 up extends to form side sheath 8.1, is set on gearbox-case
There is output shaft hole, one end of output shaft is stretched out by the output shaft hole, and output shaft hole is located in the sheath of side.In this way, being conducive to keep away
Exempt from weeds to be wound between output shaft hole and output shaft.
Specific embodiment two, remaining structure reference specific embodiment one of the present embodiment, the difference is that:
As shown in figure 3, brush cutter further includes floating sheath 11.Floating sheath is plugged in holding tank 3.1 and can be in holding tank
Depth direction on move, when the gear and blade of brush cutter up lift, to make floating sheath from recast
It is moved down with lower along holding tank, and is stretched out down by the notch of holding tank, to stop the weeds by throwing away on the cutter that rotates.It accommodates
The medial surface of slot is equipped with the guide groove 3.2 extended up and down, and the lateral surface of floating sheath is equipped with the limited block 14 cooperated with guide groove,
Limited block protrudes into guide groove.When limited block is against on the lower end of guide groove, the lower end of the floating sheath passes through the slot of holding tank
Mouth and the lower section for being located at holding tank.
It cuts weeds in operation process in brush cutter in field, when encountering ground protrusion, needs gear and knife
Piece up lifts, and during this, a part of weeds on cutter will be brushed by the notch high speed of holding tank under the action of the centrifugal force
Out, crops is struck, crops is caused to damage；This programme can not influence field cut weeds operation in the case where, effectively solve this
One problem.Since floating sheath is plugged in holding tank and can be moved on the depth direction of holding tank, cut weeds in field
In operation process, the lower end of floating sheath is against surface movement, cuts off weeds in field by blade, reaches the mesh that field is cut weeds
's；When encountering ground protrusion, when gear and blade are up lifted, floating sheath will be accommodated in Gravitative Loads lower edge
Slot moves down, and is stretched out down by the notch of holding tank, thus holding tank notch lower section formed one section of sheath, with stop by
The weeds thrown away on the cutter of rotation effectively avoid a part of weeds on cutter will be under the action of the centrifugal force by the slot of holding tank
The problem of mouth high speed brushes out, strikes crops, crops is caused to damage.
In the present embodiment, holding tank is coaxially distributed in cone, holding tank with output shaft.Floating sheath and holding tank are coaxial
Distribution.
Further, as shown in figure 3, the lower end of floating sheath 11 is located at the lower section of the notch of holding tank, floating sheath
Lower end is toward extending to form floating support plate 12 on the outside of floating sheath.Outer skew back of the outer edge of floating support plate toward floating sheath
It upwardly extends to form oriented plate 13.In this way, the lower end for being conducive to floating sheath is against surface movement, be conducive to field removal of impurities
Careless operation is gone on smoothly.
The above is only presently preferred embodiments of the present invention, is not intended to limit the invention in any way, it is all according to the present invention
Technical spirit any simple modification, change and equivalent transformation to the above embodiments, still fall within the technology of the present invention side
The protection scope of case.
