Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Fig. 1-3, a kind of mechanical arm, the cylindrical shell 2 including arm end is arranged in, in the casing 2
Coaxially be equipped with columned impeller 4, the both ends of the shaft of impeller 4 stretch out behind the upper and lower end face of casing 2 respectively with driving motor master
Axis 1 is connected with drive bevel gear 6.It is radially provided with the air jet pipe 5 protruded into casing 2 in a wherein lateral edge casing 2 for casing 2, is sprayed
Tracheae 5 is connected with compressor and weld all around is fixed between 2 side wall of casing, and the puff prot of air jet pipe 5 towards impeller 4 is rectangular flat
Mouthful, the length direction of the flat mouth is axial parallel with impeller 4, and flat opening's edge is parallel to the direction alignment leaf of 4 tangent line of impeller
For the front part of wheel 4 to drive 4 high speed rotation of impeller, the length of flat mouth is not less than the axial length of impeller 4.The machine of flat mouth face
On the side wall of shell 2 and 4 rear section of impeller pair 2 rear wall of casing on be equipped with several ventholes 3 being evenly arranged.
The left and right sides of 6 lower section of the drive bevel gear is engaged with the first driven wheel of differential 7 and second from mantle tooth respectively
