The use steps herein are described in detail below with reference to fig. 1-5:

in the initial state, the device housing 39 is at the lowermost side, the telescopic rod 47 and the articulated telescopic frame 29 are both in the contracted state, the sliding plate 40 is at the uppermost side, the wall surface protection device housing 74 is at the lowermost side, at this time, the pressure sensor 75 is not abutted to the plaster line 89, so the electromagnet 88 has no magnetism, the slide control block 83 and the pull block 76 are both at the rear side, and at this time, the motor is in the standby state.

When the device is used, the device is pushed to the lower side of the plaster line 89, at the moment, according to the installation angle of the plaster line 89, the angle adjusting hinged plate 61 is manually adjusted, the angle of the angle adjusting hinged plate 61 is parallel to the plaster line 89, at the moment, the manual rotating wheel 22 is manually rotated in the forward direction, the worm 24 is rotated, the worm wheel 26 and the threaded rod 25 are driven to rotate, due to the fact that the threaded rod 25 is in threaded fit with the sliding threaded block 28, the sliding threaded block 28 is lifted, the distance between the first section of the hinged telescopic frame 29 is increased, the corresponding distance between the following sections of the hinged telescopic frames 29 is increased, the lifting block 14 is lifted, the manual rotating wheel 22 is adjusted according to actual needs, and the distance between the angle adjusting hinged plate 61 and the plaster line 89 is kept in a proper state.

After the device is adjusted, at this time, the starting motor 30 is firstly started to rotate positively for a period of time, so that the power shaft 31, the cam 32 and the pinion 33 rotate together for a certain angle, the cam 32 moves from the minimum push stroke to the maximum push stroke, hydraulic oil in the hydraulic oil chute 17 enters the hydraulic lifting rod 70 through the connecting pipeline 41, the lifting piece 73 drives the wall surface protection device shell 74 to ascend, at this time, the pressure sensor 75 touches the lower side of a plaster line 89, an electric signal is sent to the electromagnet 88 to generate magnetism, so that the metal block 84 is attracted to drive the sliding control block 83 to move rightwards for a certain distance, at this time, the wall surface protection device shell 74 also moves rightwards for a certain distance under the action of the spring connecting rod 87, at this time, the winding rotating wheel 79 and the fixed connecting wheel 81 abut against the wall surface, and at the transmission gear 35 and the meshing transmission gear 36 rotate due to the rotation of the pinion 33, thereby make telescopic rack 38 said, make device shell 39 and roof 46 rise, after roof 46 supported the ceiling, the distance between the relative side on device shell 39 of roof 46 this moment shortens, connecting wire 44 was played out, thereby make telescopic rod 47 move to the right under the effect of spring, mounting 48 takes fixed round 49 to pull first protecting film 51 to the right this moment, make protecting film wind-up wheel 50 play first protecting film 51, first protecting film 51 shelters from between ceiling and gypsum line 89 this moment, can play the effect that blocks the spraying material.

When the first protective film 51 is opened, the driving motor 52 can be started to work for a period of time, when the driving motor 52 is started, the driving shaft 53 drives the small incomplete gear 54 and the large incomplete gear 55 to rotate, because the large incomplete gear 55 and the small incomplete gear 54 are both provided with partial gears, when a gear part is meshed with the first meshed gear 68 and the second meshed gear 57, transmission can be realized, when the gear part is separated, the first meshed gear 68 or the second meshed gear 57 can rotate reversely and return, firstly, when the small incomplete gear 54 is meshed with the first meshed gear 68, the reel 69 rotates forwards to withdraw the pull rope 66, the sliding piece 64 is pulled to the lowest side of the spraying chute 62 from the uppermost side of the spraying chute 62, the spraying device 65 is started to spray the paint, then the small incomplete gear 54 is separated from the first meshed gear 68, the reel 69 is reversed and returned, the sliding piece 64 is made to return to the original position, at the moment, the large incomplete gear 55 drives the second meshing gear 57 to rotate, the large gear 58 rotates to drive the meshing sliding block 59 and the angle adjusting hinged plate 61 to move forwards together, the angle adjusting hinged plate 61 moves forwards, the spraying device 65 moves up and down simultaneously, the coating is uniformly sprayed on the section of gypsum line 89, in the process that the meshing sliding block 59 moves forwards, the connecting rope 60 is retracted, the connecting rope 60 pulls the pulling block 76 forwards and synchronously moves forwards with the angle adjusting hinged plate 61, at the moment, the winding rotating wheel 79 emits the second protective film 80, so that the second protective film 80 is blocked between the wall surface and the gypsum line 89, and the spraying material is placed to pollute the wall surface.

After a period of movement, the large incomplete gear 55 is disengaged from the second meshing gear 57 at this time, so that the large gear 58 rotates reversely, the angle adjusting hinged plate 61 returns to the original position, the pulling block 76 also returns to the original position under the action of the spring connecting rod 87, at this time, due to the action of the torsion spring, the winding rotating wheel 79 retracts the second protective film 80, and the spraying device 65 does not work in the recycling process.

After the use is finished, the starting motor 30 is started reversely at the moment, so that the device shell 39 is reset, the wall surface protection device shell 74 is also reset together, the pressure sensor 75 is not abutted to the plaster line 89 any more at the moment, the electromagnet 88 loses magnetism, and the sliding control block 83 is reset.

The invention has the beneficial effects that: the invention relates to a device capable of specially spraying plaster lines, wherein a nozzle can be lifted to a spraying position through the device, the spraying angle between the plaster lines by a spray head can be adjusted according to the installation angle of the plaster lines, and after the device is started, the plaster lines can be separated from the area between a ceiling and a wall surface through the device, so that sprayed paint can not be sprayed on the ceiling or the wall surface during re-spraying, color mixing and later-stage treatment are avoided, the spraying efficiency is improved, the device can be automatically positioned, and the spraying is uniform through transmission control during spraying, so that excessive or insufficient paint sprayed at partial positions is not easily caused.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
