[0019] Since the cone bottom 7 at the bottom of the material cylinder 6 can be adjusted up and down, the storage space formed by the material cylinder 6 and the cone bottom 7 is adjustable in size, which can be used to measure the heat preservation covering agent. According to different riser specifications, the discharge amount of heat preservation covering agent is adjusted to play a role while avoiding waste.

[0020] A first motor 10 for driving the turntable 3 is provided at the bottom of the fixed table 1. The first motor 10 controls the rotation of the turntable 3 to switch the barrel 6 corresponding to the position of the riser, and stops running when adding materials to ensure that the thermal insulation covering agent accurately covers the riser. The thermal insulation covering agent is added to the barrel 6 away from the end of the riser, and the material is added when it rotates to the riser position.

[0021] A horizontal rotating shaft 11 is provided above the turntable 3 for rotation. A second motor 12 for driving the rotating shaft 11 is provided above the turntable 3.
