[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this extrusion device, when the motor is working, it drives the first rotating shaft to rotate. The first rotating shaft drives the second rotating shaft to rotate through the second pulley, the belt and the first pulley. The second rotating shaft drives the agitator to rotate. As the agitator rotates, it facilitates the material to fall quickly into the extrusion box. The first rotating shaft drives the screw rod to rotate. The screw rod pushes the material to move. The material is extruded through the connecting pipe to the first extrusion head.

[0017] When the first extruder head needs to be replaced, the first electric push rod retracts, and the first electric push rod drives the third support plate to move. The third support plate drives the second support plate to move upward through the first connecting rod and the second connecting rod. The second support plate drives the concave connecting plate to move upward, so that the top of the concave connecting plate abuts against the first extruder head, and the first connector head is disassembled. The disassembled first connector head is caught by the top of the concave connecting plate, which makes it easy to quickly put down the first connector head.

[0018] The second electric push rod extends, and the second electric push rod drives the concave connecting plate to move through the third connecting block. The concave connecting plate drives the first connecting head to leave the connecting tube. The first electric push rod extends, and the first electric push rod drives the concave connecting plate to move downward through the third support plate, the first connecting rod, the second connecting rod, and the second connecting plate. The concave connecting plate drives the first extrusion head to move downward and remove the first extrusion head.

[0019] The second extruder head is placed on the concave connecting plate. The first electric push rod retracts, driving the third support plate to move. The third support plate, through the first and second connecting rods, drives the second support plate upward. The second support plate drives the concave connecting plate upward. The concave connecting plate drives the second extruder head upward to a suitable height. The second electric push rod retracts, driving the concave connecting plate through the third connecting block. The concave connecting plate drives the second connecting head to move towards the connecting tube, so that the second extruder head and the connecting tube fit together, facilitating quick fixation of the second extruder head and the connecting tube, and facilitating quick replacement of the first extruder head.

[0020] The application of the above-mentioned extrusion device in the production of coal gangue sintered bricks can reduce the number of people required to change the extrusion head in emergency situations such as rush production. This allows more people to do other production work and reduces the pressure of rush production. Attached Figure Description
