Spraying gun water spot adjusting device

Abstract

The invention relates to a spraying gun water spot adjusting device. The spraying gun water spot adjusting device comprises an inner casing pipe installed at the end portion of a spraying gun water pipe, a dabber connected with the interior of the inner casing pipe and a shell with one end arranged on the outer wall of the inner casing pipe in a sleeved mode; the dabber and the inner casing pipe are parallel in the axial direction, and a gap is reserved between the dabber and the inner wall of the inner casing pipe; one end of the dabber is connected with the inner wall of the inner casing pipe through a dabber frame with a through hole; the other end of the dabber is a free end; the free end extends out of the inner casing pipe; a horn-shaped water dispersing device is arranged at the free end of the dabber; the diameter of the horn-shaped outer edge of the water dispersing device is greater than the diameter of the dabber; the shell and the inner casing pipe are in sliding connection; when the shell gets close to one side of the spraying gun water pipe, the water dispersing device is located outside the shell; and when the shell slides to be away from the spraying gun water pipe,the water dispersing device is completely located inside the shell, and an electric push rod device controls the shell to slide. The size and shape of water spots of a spraying gun can be electrically controlled and adjusted in a cab, the working efficiency is improved, and the working environment is improved.

Description

technical field [0001] The invention relates to the field of sprinkler spray guns for sanitation gardens, in particular to an automatic spray gun water spray adjustment device. Background technique [0002] At present, the water spray adjustment device of the spray gun used in the sprinkler cannot be conveniently operated in the cab, and manual adjustment is required during the use process, the working conditions are harsh, and the adjustment efficiency is low. When it is necessary to wash the road surface, the columnar water flow is used to wash the road surface. When it is necessary to spray flowers and plants, it needs to be manually adjusted to a mist-like water flow, and then spray the trees. The work efficiency is low, and the size of the water spray and the range of the water column are limited. The automatic conversion of the size of the water splash has brought a lot of inconvenience to the sanitation staff. Contents of the invention [0003] The technical proble...
