The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical solution of the present invention is done further nonrestrictive detailed description.
Seeing figures.1.and.2, is chipper 10 in the garden instrument corresponding to the cutting tool of preferred embodiment of the present invention, and it is used for the chopping of branch so that the transportation of the branch after the chopping, bury or other processing, mainly comprises head part 12 and bracing frame 14.The driver part (not shown) is set in head part 12, by the cutting part 1 of 12 high-speed driving of driver part, so that material to be cut branch 7 is shredded.
With further reference to Fig. 3 to Fig. 5, above-mentioned cutting part 1 comprises cutterhead support 3 and is installed in several blade 5 on the described cutterhead support 3.This cutterhead support 3 is roughly disc, and its center arranges axle sleeve 32 and is positioned at the rotation E of axle sleeve 32, and has periphery wall F, and this periphery wall F has the first diameter L1.Described cutterhead support 5 is formed in one, and is provided with the equal erecting bed 36 of a plurality of spacings so that corresponding blade 5 to be installed at the periphery wall F of cutterhead support 3.As shown in Figure 6 and Figure 7, each erecting bed 36 comprises that several locating surfaces 33 are to support above-mentioned blade 5.Described locating surface 33 comprises a vertical plane 37 and a pair of horizontal plane 38, described horizontal plane 38 and described vertical plane 37 are thin-and-long, contact with bottom surface and the side of described blade 5 respectively, this just contacts with the sub-fraction of the bottom surface 57 of described blade 5 to horizontal plane 38 like this, and vertical plane 37 and horizontal plane 38 all are parallel to each other with described rotation E.Also one-body molded between this is to horizontal plane 38 have an a pair of installing hole 39, and its shape is roughly U-shaped, is distributed in the inside and outside both sides of periphery wall F.And blade 5 arranges screw hole 54, and installing hole 39 interconnects by screw 56 with screw hole 54.In addition, erecting bed 36 also is provided with and described blade 5 non-contacting inclined planes 53, and corresponding to preferred embodiment of the present invention, plane 38 is 1: 5 with the area on inclined plane 53 than probably; Like this, be the contacting of facet area between blade 5 of the present invention and the cutterhead support 3, because if the area of plane that should contact is too big, depanning difficulty or do not go out mould in the time of can causing 3 depannings of cutterhead support is because need very big withdrawing pattern power; And if all make the inclined plane, depanning meeting ratio is easier to, but blade 5 will be installed also need the later stage machined, causes manufacturing cost to rise.So the way of contact of this small size has guaranteed the one-body molded smoothly of cutterhead support 5, need not following process, and is so manufacturing process is simple, with low cost.
