Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to exterior wall paint spraying equipment. Background Art

[0002] Exterior wall paint is used to paint the exterior walls of buildings, so the most important indicator is resistance to ultraviolet radiation, which requires it to not change color under long-term exposure. Since 2013, energy-saving and environmentally friendly liquid stone water-based paint has attracted more and more attention. Some exterior wall paints are also required to have water resistance and self-cleaning properties.

[0003] During the paint spraying process, the raw material liquid will gradually solidify, which will not only easily cause the nozzle to be blocked, but also affect the spraying effect. The existing exterior wall spraying equipment generally does not have the function of quickly stirring the paint, so corresponding improvements are made to address this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an exterior wall paint spraying device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The cam is fixed on the bottom of the cylinder and a handle is fixed on the base. A plurality of universal wheels are installed at the bottom of the base. A pair of stirring frames are arranged in the cylinder. The central axis of the stirring frame is rotatably connected with the cylinder. A gear is fixed on the central axis of the stirring frame. A U-shaped pull rod that can move laterally is provided on the top of the cylinder. A pair of support frames sliding on the cylinder are provided at the bottom of the pull rod. The inner walls on both sides of the pull rod are provided with tooth surfaces meshing with the gears. There are flat surfaces on both sides of the tooth surfaces. The cylinder is connected with a spraying assembly. The pull rod is pulled quickly to one side first. The pull rod drives the gear to rotate through the engagement of the tooth surfaces. The gear synchronously drives the stirring frame to rotate until one of the planes moves to the gear and the pull rod is stopped. At this time, the stirring frame will rotate due to inertia, thereby stirring the paint in the cylinder to prevent the paint from solidifying. After the speed of the stirring frame becomes very slow or stops, the pull rod can be pushed back quickly until the other plane moves to the gear and stops, thereby repeatedly driving the stirring frame to rotate.

[0007] Preferably, a feed pipe is provided on the top of the cylinder, a tube cover is threadedly connected to the feed pipe, and a transparent plate is embedded in the outer wall of the cylinder. The amount of paint in the cylinder can be visually checked through the transparent plate. When the paint is insufficient, the paint can be added to the cylinder through the feed pipe.

[0008] Preferably, a fixing plate is fixed on the top of the cylinder, and a limiting rod is inserted in the limiting hole on the fixing plate. One end of the limiting rod is fixedly connected to the pull rod, and both ends of the limiting rod are sleeved with springs, one end of the spring is fixed on the limiting rod. The maximum stroke of the pull rod to the left and right can be determined by the limiting rod. When it moves to the maximum stroke, the plane is just at the gear, which makes it more convenient to operate the pull rod, and the spring can buffer the limiting rod, so that excessive force on the pull rod will not cause a violent collision.

[0009] Preferably, an auger is rotatably connected to the top of the cylinder, and pulleys are fixedly sleeved on the central axis of the auger and one of the stirring frames. The two pulleys are connected by a belt. When the stirring frame rotates, the auger is driven to rotate through the transmission cooperation of the pulley and the belt. The auger stirs the settled paint at the bottom of the cylinder upward, thereby preventing the paint from settling.

[0010] Preferably, the spray assembly includes a liquid pump, which is connected to the cylinder by a hose, and to the nozzle by a delivery pipe. When the liquid pump is powered on, the paint in the cylinder is extracted through the hose, and the paint enters the nozzle through the delivery pipe and is sprayed out, and the wall can be sprayed.

[0011] Preferably, a slide rail is fixed on the base, an electric slider is slidably connected to the slide rail, and the electric slider is fixedly connected to the liquid pump. During the spraying process, the electric slider will drive the liquid pump and the nozzle to move back and forth along the slide rail, so that the wall can be evenly sprayed.

[0012] The beneficial effects of the utility model are:

[0013] 1. The device is equipped with a stirring frame. First, pull the pull rod quickly to one side. The pull rod drives the gear to rotate through the tooth surface engagement. The gear synchronously drives the stirring frame to rotate until one of the planes moves to the gear and then stops pulling the pull rod. At this time, the stirring frame will rotate due to inertia, thereby stirring the paint in the cylinder to prevent the paint from solidifying. After the speed of the stirring frame becomes very slow or stops, the pull rod can be pushed back quickly until the other plane moves to the gear and stops, thereby repeatedly driving the stirring frame to rotate.

[0014] 2. A limit rod is provided in the device, which can determine the maximum stroke of the pull rod to the left and right. When it moves to the maximum stroke, the plane is just at the gear, which makes it more convenient to control the pull rod, and the spring can buffer the limit rod, so that excessive force on the pull rod will not cause a violent collision.

[0015] 3. The device is equipped with an auger. When the stirring frame rotates, the auger is driven by the transmission of the pulley and the belt. The auger stirs the precipitated paint at the bottom of the cylinder upward to avoid the sedimentation of the paint. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the stirring frame 2 will rotate due to inertia, thereby stirring the paint in the cylinder 1 to prevent the paint from solidifying. After the speed of the stirring frame 2 becomes very slow or stops, the pull rod 4 can be pushed back quickly until the other plane 6 moves to the gear 3 and stops, so that the stirring frame 2 can be driven to rotate repeatedly.

[0023] Furthermore, a feed pipe 8 is provided on the top of the cylinder 1, and a pipe cover 9 is threadedly connected to the feed pipe 8. A transparent plate is embedded in the outer wall of the cylinder 1. The amount of paint in the cylinder 1 can be visually viewed through the transparent plate.
