After the quartz crucible is broken, it is separated from the carbon-carbon crucible, and the carbon-carbon crucible is reused. However, during the knocking process, it is difficult to control the manual knocking force, and the knocking point is unique. The carbon-carbon crucible is indirectly or directly knocked by the hammer, which will cause damage to the carbon-carbon crucible wall and reduce the service life of the carbon-carbon crucible wall.

A set of inclined rods is fixed on the outer wall of the guide seat. The inclined rods are evenly distributed along the axial direction of the guide seat and are arranged directly below the connecting ears. One end of the third rod is hinged to the inclined rod to form a linkage mechanism.

[0008] The ends of the second rods are all connected to a hammer head. The height and angle of each hammer head are the same. The hammer heads are arranged facing the L corner of the quartz crucible to knock the quartz crucible at equal angles and equal heights.

[0009] Furthermore, a material receiving device is provided at the lower part of the base. A placement platform is provided at the top of the material receiving device.

[0017] Furthermore, the lifting cylinder is connected to an external air compressor through an air pipe, and a pressure reducing valve is connected at the joint to provide power for the lifting cylinder.

[0018] In the technical solution of the present invention, an air compressor is used as the air source device to provide the power source for this tooling. The air compressor transmits the gas pressure to the cylinder, and the cylinder converts the air pressure into mechanical energy. Through lifting, the hammer heads strike the L corner of the quartz crucible at the same angle and height simultaneously, and a pressure reducing valve is used to control the pressure magnitude. After the L corner of the quartz crucible is broken, it falls out from the lower edge of the crucible wall, and the quartz crucible above the L corner drops, ending the knocking of the crucible. The device of the present invention reduces the manual labor consumption required for knocking the quartz crucible, reduces the working hours for disassembling and cleaning the hot field, increases the service life of the carbon-carbon crucible wall, reduces the production cost, and improves the work efficiency.
