The control box 2 is equipped with a controller 4, a memory 5 and a power supply 6. The heating and heat preservation module includes multiple heating wires 7, a temperature sensing resistor 8 and two symmetrically arranged support plates 9. The multiple heating wires 7 and the temperature sensing resistor 8 are all inserted between the two support plates 9 for monitoring the temperature and heating the slurry.

[0027] In this embodiment, a crossbeam 10 is fixedly connected to the inner top of the main shed 1 to support the slider 11. The crossbeam 10 is fixedly connected to the inner wall of the main shed 1 by multiple reinforcing plates 16. Multiple sliders 11 are slidably sleeved on the crossbeam 10. A connecting block 12 is fixedly connected to the bottom of the slider 11 to facilitate the connection of the spraying mechanism. Multiple connection ports are provided on the connecting block 12.

[0030] In this embodiment, the temperature of the slurry can be monitored by the temperature sensing resistor 8, and then the monitoring signal is sent to the controller 4. After processing the monitoring data, the controller 4 controls the electric heating wire 7 to start, so as to heat and keep the slurry warm. At the same time, the main shed body 1 can effectively play a protective and heat-preserving role. The position of the connecting block 12 can be adjusted by sliding the slider 11, and the position of the slider 11 can be fixed by the clamping mechanism. Then, the spraying mechanism is connected and fixed to the connecting block 12 through the connection port.
