A kind of cement mixer emergency stop device
Technical field
The present invention relates to mixer field, specially a kind of cement mixer emergency stop device.
Background technology
At present, cement mixer is widely used in building engineering field, is mainly used in mixing cement, sandstone etc., existing
Cement mixer lacks emergent stopping structure, can only stop electric notor by closing master switch in the case of needing emergent stopping
Work stops, thus stopping stirring vane work, yet with inertia force, stopping completely needing one section from closing switch to blade
Time is it is impossible to realize stopping immediately, in addition, because electric notor is fixedly connected by a series of transmission devices with blade, such as
Fruit now can not be closed electric notor at once and so that it is persistently rotated it is most likely that causing electric notor to burn.

Further, whole specifications of described double wedge and whole specifications of described recess are identical.
Further, the centre of described 3rd swivel has been provided with spiral shell in place in the inner between wall and the end of second driving shaft
Spring.
Further, described helical spring is in impaction state.
Further, the specification of described guide post is less than the specification of described pilot hole.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is used for connecting the output shaft of electric notor and the axostylus axostyle of stirring vane, when occur standby stirring material excess phenomenon or
When needing emergent stopping, the position for connecting can disengage in time, and now, the output shaft of electric notor can normally rotate, and
Will not be affected by external forces, thus preventing electric notor from burning the generation of phenomenon.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of embodiment that the present invention provides:A kind of cement mixer emergency stop device,
Including for connecting multipair stirring blade 21 the 3rd power transmission shaft 1 in hood 22 and the first power transmission shaft for connecting electric notor
2 it is characterised in that:One end of described first power transmission shaft 2 is fixed with the first swivel 17, and described 3rd power transmission shaft 1 is towards described
One end of first swivel 17 is fixed with the 3rd swivel 3, and for sky in the middle of described 3rd swivel 3, and centre is connected by connection protuberance 5
There is the second driving shaft 4 being plugged in the middle of the 3rd swivel 3, one end of described second driving shaft 4 is fixed with the second swivel 7, described
Second swivel 7 is being provided with many guide posts 9 towards the described first swivel 17 end face, and the spacing of many guide posts 9 and between centers
Angle is identical, and described first swivel 17 is provided with multiple pilot holes 20 in the end face turning 7 in the face of described second, and described many are led
Can be plugged in the plurality of pilot hole 20 to bar 9, the outer ring surface of described second swivel 7 is fixing with the inner layer of supporting member even
Connect, the surface of the outer layer of described supporting member is fixed with connecting plate 8, and the bottom of described connecting plate 8 is fixed with armed lever 10, described armed lever 10
