4results about How to "Avoid spraying dead ends" patented technology

The application discloses a dustproof spraying device for building construction and belongs to the technical field of dustproof equipment for building construction. The device comprises a horizontal cavity, a water storage groove is symmetrically arranged on the upper surface of the horizontal cavity, a cavity is arranged on the upper surface of the horizontal cavity, a circular cavity is fixedly connected to the inside of the cavity, a central cavity is fixedly connected to the inside of the circular cavity, a motor is fixedly connected to the lower surface of the central cavity, an output end of the motor is fixedly connected with a rotating column, and a limiting block is arranged on the outer side wall of the rotating column. The device is driven to rotate by the motor, the rotating column is driven to rotate by the limiting block and the limiting groove, and the guiding sliding block is slid in the guiding curved groove to make the perforated turntable produce up-down reciprocating motion. The composite motion makes the liquid pumping circular plate slide up and down in the liquid pumping groove, and the efficient water pumping and water feeding are realized by cooperation of the one-way water valve, so that the spraying ring can continuously obtain water source.

The utility model belongs to the technical field of crop sprinkling irrigation, and discloses a water sprayer and a sprinkling irrigation spray gun, the water sprayer comprises a first connecting pipe, a second connecting pipe and at least two sprayer assemblies, the water inlet end of the first connecting pipe is used for being connected with external water supply equipment in a sealing mode; the second connecting pipe is in sealed through connection with the first connecting pipe and is provided with at least two water outlets; each spray head assembly comprises an adapter tube, a universal adjusting piece and a spray head, the first end of each adapter tube is detachably and hermetically connected with each water outlet of the second connecting tube, the second end of each adapter tube is connected with the universal adjusting piece, the universal adjusting piece can freely adjust the spraying angle in multiple directions, and the spray head is installed at the water outlet end of the universal adjusting piece. The device is used for directionally spraying water flow to a target area. The spraying device has a large spraying angle and a wider coverage area, can effectively avoid spraying dead angles, has good adaptability, and is suitable for irrigation requirements of different crops.

The utility model relates to a spraying device technical field, concretely relates to a kind of pipe inner wall automatic spraying device, including support, support one end is fixedly installed with No. 1 board and No. 2 board, No. 1 board surface is equipped with multiple No. 1 sliding slot, clamping jaw is slidably connected in No. 1 sliding slot, the surface of No. 2 board close to No. 1 board is rotatably connected with carousel, carousel surface is equipped with multiple arc sliding slot, the center of No. 1 board is fixedly installed with sliding bearing, sliding bearing is slidably connected with round bar, round bar is hollow inside, and paint spraying head is fixedly installed in round bar end close to clamping jaw, the upper surface of support is fixedly installed with slide rail, and the surface of slide rail is slidably connected with No. 3 board.The utility model adjusts the clamping jaw position, and different specifications pipe is stably clamped, and round bar and paint spraying head are in-depth pipe inner cavity, while round bar rotation drives paint spraying head to rotate when spraying, solve the problem that traditional equipment spray head is difficult to stretch into long pipe internal, can cover the whole segment inner wall of long pipe, avoid spraying dead angle.

The utility model relates to the technical field of pipeline anti-corrosion, and discloses an anti-corrosion spraying device for the inner wall of a pipeline, which comprises a bottom plate. A first inner support mechanism is fixedly connected to the top end of the bottom plate. The first inner support mechanism comprises a fixing plate which is fixedly connected to the top end of the bottom plate. One end of the fixing plate is fixedly connected with a first air cylinder. A first telescopic rod is slidably connected to the inner cavity of the first air cylinder. One end of the first telescopic rod is fixedly connected with a driving column. A first connecting shaft is rotatably connected to the outer side of the driving column. A first connecting plate is rotatably connected to the outer side of the first connecting shaft. An inner support plate is hinged to the outer side of the first connecting plate. A second connecting plate is hinged to one side of the inner support plate. A second connecting shaft is rotatably connected to the end of the second connecting plate far away from the inner support plate. The first inner support mechanism can adjust the opening amplitude of the inner support plate according to the inner diameter of the pipeline, so that the device is firmly supported on the inner wall of the pipeline, ensuring the stability of the device during the spraying process and avoiding uneven spraying caused by shaking.
