[0002] At present, cement mixers are widely used in the field of construction engineering, mainly for mixing cement, sand and gravel, etc. The existing cement mixers lack an emergency stop structure. When an emergency stop is required, the electric motor can only be stopped by turning off the main switch to stop the work. Stop the stirring blades to work, however due to the inertial force, it will take some time from turning off the switch to the complete stop of the blades, and it cannot be stopped immediately. In addition, since the electric motor and the blades are fixedly connected through a series of transmission devices, if it cannot be closed immediately at this time If the electric motor keeps rotating, it is very likely to cause the electric motor to burn out

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see figure 1 , figure 2 , image 3 and Figure 4 , an embodiment provided by the present invention: an emergency stop mechanism of a cement mixer with an illuminating device, including a third transmission shaft 1 for connecting multiple pairs of stirring blades 21 in the hood 22 and a third drive shaft 1 for connecting an electric motor. A transmission shaft 2, characterized in that: one end of the first transmission shaft 2 is fixed with a first r...

The invention discloses a cement mixer emergency stopscramming mechanism with a lighting device. A first turning body is fixed to one end of a first transmission shaft; a third turning body is fixed to one end, facing the first turning body, of a third transmission shaft; the middle of the third turning body is empty; a second transmission shaft inserted in the middle of the third turning body is connected to the middle through a connecting convex part; a second turning body is fixed to one end of the second transmission shaft; a plurality of guide rods are arranged at one end face, facing the first turning body, of the second turning body; the spacings and the interaxial angles of between the guide rods are the same; a plurality of guide holes are formed in one end face, facing the second turning body, of the first turning body; the guide rods can be inserted into the guide holes. According to the cement mixer scramming mechanism with the lighting device provided by the invention, when materials to be stirred are exceeded excessive or emergency stop is needed, a part for connecting can be separated in time, and at the time, an output shaft of an electric motor can rotate normally without being influenced by an exoteric force, so that the occurrence of the phenomenon that the electric motor is burnt is prevented.
