A drainage pipeline inner wall mortar sprayer according to claim 3, wherein: the front frame is also provided with a proximity sensor which is connected with the programmable controller and used for detecting obstacles; the programmable controller is also connected with an alarm, the proximity sensor detects the obstacle in front of the front frame in real time and sends a detected real-time distance signal to the programmable controller, and the programmable controller compares the real-time detected distance signal with a corresponding distance threshold value after data conversion and controls the alarm to give out an alarm according to the comparison result; when the real-time detected distance value is smaller than a preset distance threshold value, the programmable controller controls the alarm to give out alarm sound; otherwise, the message is not sent out.
6. A method of using a drain pipe inner wall mortar sprayer according to any of claims 1-5, comprising:
1) Pretreatment: the inner wall surface of the drainage pipeline is washed clean by high-pressure water before spraying operation, so that the inner wall of the pipeline is clean, mud-free and greasy dirt-free;
2) And (3) assembling: after the cleaning of the inner wall of the drainage pipeline is completed, the mortar spraying machine is assembled, a mortar conveying power assembly, a walking power assembly, a mortar spraying power assembly and a mortar trowelling power assembly are sequentially hoisted, and the mortar spraying power assembly, the walking power assembly, the mortar spraying power assembly and the mortar trowelling power assembly are combined into a whole in a detachable mode to complete the underground assembly of the whole machine;
3) And (3) mortar spraying construction: filling mortar into the mortar storage cylinder assembly, controlling the mortar conveying rod to rotate for pre-stirring the mortar, preventing the mortar from segregating, and controlling the front wheel set and the rear wheel set to move the spraying machine to a preset position; when the mortar is moved to a preset position, a mortar conveying rod is controlled to convey mortar to a mortar spraying disc, after the mortar spraying disc is used for spraying mortar, a mortar trowelling power assembly is simultaneously opened, a spraying machine is controlled to advance or retreat, the mortar is sprayed to the periphery of the pipe wall at a high speed, so that the mortar is uniformly adhered to the pipe wall, and meanwhile, a trowelling sheet of the mortar trowelling power assembly trowells the pipe wall to form a mortar coating with a smooth surface and uniform thickness; and (5) supplementing mortar into the slurry storage barrel assembly in time in the whole spraying process, so as to complete the whole pipeline spraying process.
