The invention provides an energy-saving type mud-head-free automatic green
brick cutting device. A green
brick cutting frame right faces an opening of an extruding
machine and is fixedly arranged in the mud strip conveying direction of a mud strip conveyor, a mud strip positioning wheel is arranged in front of the green
brick cutting frame, a tackle is arranged on the lower portion of the interior, a self pressing type rolling press roller is arranged on the upper portion of the interior, the tackle is provided with a cutting device, the cutting device is connected with a
speed reduction motorthrough a
crank connecting rod mechanism and is continuously driven by the
speed reduction motor to periodically reciprocate up and down to
cut green bricks, the
speed reduction motor intermittentlydrives the tackle to retreat and reset through a
clutch, the tackle and the mud strip conveyor are in automatic intermittent disconnection or connection through a
ratchet-pawl mechanism, the
crank connecting rod mechanism achieves engaging and disengaging switching of the
clutch through the
cam mechanism and a shifting fork, the self pressing type rolling press roller is attached to the mud stripand the upper end faces of the green bricks all the time and is matched with all devices to
cut the green bricks. The device is compact in structure, small in occupied area, energy-saving, and capableof reducing consumption and emissions. In the green brick cutting process, no mud head exists, no remaining materials are generated, the cost is low, maintaining is easy, and the device is easy to popularize.
