Building wall surface spraying device capable of preventing coating from drifting away

Abstract

The invention relates to a building wall surface spraying device capable of preventing paint from drifting away, and relates to the field of paint spraying technologies, the building wall surface spraying device comprises a rack, a spraying gun is installed on the rack, the feeding end of the spraying gun communicates with a feeding pipe, and the end, away from the spraying gun, of the feeding pipe is connected with a raw material supply assembly; a protection cover is arranged on the rack, and a spraying protection space is defined by the protection cover on the peripheral side of the spraying gun; the protection cover is provided with a first position adjusting mechanism suitable for driving the spray gun to move transversely and vertically in the spraying protection space. The rack is provided with a position adjusting mechanism suitable for driving the protection cover to transversely and longitudinally move along the plane where the wall face is located. The rack is provided with an obstacle recognizing and avoiding mechanism suitable for scanning obstacles on the wall and controlling the protective cover to avoid the obstacles. The paint spraying device has the advantages that paint airflow sprayed by the spraying gun is not prone to being opposite to air in the protective cover to form turbulent flow, and the protective cover is not prone to colliding with obstacles on the wall in the moving process.

Description

technical field [0001] The present application relates to the field of paint spraying technology, in particular to a spraying device for preventing paint from drifting away on building walls. Background technique [0002] In the construction of construction projects, it is often necessary to spray paint on the surface of the building wall, and to decorate and protect the wall by spraying paint on the wall. [0003] A Chinese patent document whose notification number is CN213626508U discloses a paint spraying device for construction engineering. The spray gun is connected with the paint equipment, the outside of the spray gun is fixedly connected with a protective cover, and the inside of the protective cover is fixedly connected with a mounting plate. The movable plate is connected with the spring, and the top edge of the protective cover is plugged with a scraper. The side of the scraper away from the movable plate is fixedly connected with a screw extending to the outside...

Problems solved by technology

[0004] For the above-mentioned related technologies, the inventor thinks that there is the following defect: when the spray gun is carrying out the paint spraying operation on the wall, under the partition of the inner wall of the protective cover, the air flow of the paint sprayed by the spray gun is easily connected with the air in the protective cover. Air hedging forms turbulent flow, which makes it difficult for the paint sprayed by the spray gun to be evenly sprayed on the wall; in other related technologies, the protective cover with the spray gun can also move by itself along the surface of the wall through the driving component. The protective cover is easy to collide with obstacles on the wall during the moving process, so that the spraying effect of the spray gun on the wall is not good
