With the ash discharge mechanism in operation, the discharge port of the ash discharge assembly 210 is in communication with the feed port of the mixer 110 such that material can be transported between the ash discharge assembly 210 and the mixer 110.

Under the condition of adopting the technical scheme disclosed by the embodiment of the application, because the required driving force is relatively small, and then the driving wheel 310 can be a manual driving device, the number of the components in the ash discharging mechanism can be reduced, the reliability of the whole ash discharging mechanism is improved, and the energy consumption can be reduced.

Certainly, in order to further improve the automation degree of the ash discharging mechanism and save the labor of the workers, the ash discharging mechanism disclosed in the above embodiment may further include a driving motor, and the driving motor is in transmission connection with the driving wheel 310 to drive the driving wheel 310 to rotate through the driving motor, so as to drive the ash discharging assembly 210 to rotate relative to the mixer 110, so as to switch the ash discharging assembly between the working state and the non-working state. Specifically, the driving motor and the driving wheel 310 may be directly connected, or indirectly form a transmission relationship through a belt transmission member or a gear set 320, so as to ensure that the driving motor can transmit the driving force to the driving wheel 310.

In the case that the driving wheel 310 drives the ash discharging assembly 210 to rotate relative to the mixer 110 through the rotating shaft, the ash discharging mechanism disclosed in the embodiment of the present application may further include a gear set 320, and the driving wheel 310 is in transmission connection with the rotating shaft through the gear set 320, and the transmission ratio between the driving wheel 310 and the rotating shaft is greater than 1. In this case, the driving force required by the driving wheel 310 to rotate the hinge 220 via the shaft can be reduced, thereby reducing the difficulty in driving the ash discharging assembly 210.

In the case of driving the ash discharging assembly 210 by the winch 330 and the cable 340, a driving motor may be provided for the winch 330, and the driving motor is in transmission connection with the winch 330, so that the driving motor is used to drive the winch 330 to rotate, thereby increasing the automation degree of the ash discharging mechanism and further reducing the labor amount of the worker.

In another embodiment of the present application, a driving wheel 310 may also be disposed on the winch 330, the driving wheel 310 is in transmission connection with the winch 330, and the diameter of the driving wheel 310 is larger than that of the winch 330, so that the driving wheel 310 and the winch 330 form a labor-saving lever, and the driving force required by the winch 330 to drive the ash discharging assembly 210 to rotate is reduced. Alternatively, a gear set 320 may also be provided between the drive wheel 310 and the winch 330 to increase the gear ratio between the drive wheel 310 and the winch 330, which may also reduce the drive force of the drive wheel 310. In order to reduce the number of parts required to be disposed in the ash discharging mechanism, the driving wheel 310 can be manually rotated to rotate the ash discharging assembly 210 relative to the mixer 110 via the winch 330 and the cable 340 according to the above embodiments.

In another embodiment of the present application, the ash discharging mechanism may further include a damping member, which may be a damping gear set, and the damping member is disposed between the hinge base 120 and the hinge 220 to limit the rotation of the ash discharging assembly driven by its own weight.

More specifically, one end of the base can be rotatably mounted to the frame 400, and the driving end of the driving shaft can be rotatably mounted to the bottom ash assembly 210 by a pin, a bushing, and the like. Of course, during the installation of the linear driving assembly 350, the driving force direction of the linear driving assembly 350 is required to correspond to the turning direction of the ash discharging assembly, so as to ensure that the linear driving assembly 350 can drive the ash discharging assembly to turn relative to the mixer 110.
