The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a hand-push cold spray marking machine, such as Figure 1-4 As shown, it includes a cold spray road marking machine body 1, two hand push handles 2 are symmetrically fixedly connected to the outer wall of one side of the cold spray road marking machine body 1 by bolts, and a nozzle fixing frame 3 is fixedly connected to the outer wall of one side of the cold spray road marking machine body 1 adjacent to the two hand push handles 2 by bolts, the bottom of the nozzle fixing frame 3 is fixedly connected to the marking nozzle 4 by bolts, and a spray pipe 5 is embedded in the top of the nozzle fixing frame 3 near the upper position of the marking nozzle 4, the bottom of the nozzle fixing frame 3 is rotatably connected to the first ball screw 61 in the dust blocking assembly 6 at a position near the side of the marking nozzle 4, one end of the first ball screw 61 is provided with a second ball screw 62, and the other end of the first ball screw 61 is provided with an adjusting disk 63, the nut seats on the first ball screw 61 and the second ball screw 62 are fixedly connected to the baffle 64 by nuts, and the bottom of the baffle 64 is fixed with a rubber pad 65 by adhesive.

[0021] It should be noted that, since the existing cold spray marking sprayer will inevitably generate wind during spraying, the dust on its bottom surface will be blown, so that the spray and dust are mixed together, which not only affects the smoothness of the sprayed surface, but more importantly, reduces the quality after spraying. In this embodiment, the two baffles 64 in the dust blocking component 6 are blocked on both sides of the marking nozzle 4, which can not only be adjusted according to the width of the spraying marking line, but also can block the wind on both sides of the marking nozzle 4, thereby preventing the wind from causing the ground dust to be lifted up and mixed with the spray material, and the dust and sand and gravel particles on the ground along the spraying line are removed through the dust cleaning component 7, thereby ensuring the smoothness of the ground spraying surface and improving the quality of the spraying.

[0022] Specifically, in the present embodiment, the scheme mainly includes a dust blocking component 6 and a dust cleaning component 7. Before spraying and marking, the distance between the two baffles 64 is adjusted according to the width of the spraying and marking line, so that the baffles 64 are located on both sides of the marking line, and the adjusting disk 63 is rotated. The adjusting disk 63 drives the first ball screw 61 and the second ball screw 62 to rotate, and the baffles 64 on the first ball screw 61 and the second ball screw 62 move toward or oppositely to achieve the adjustment of the distance. When spraying, the hand push handle 2 is held to push the cold spray marking machine body 1 to move along the marking line, and the spray material enters the marking nozzle 4 through the spray pipe 5. The marking nozzle 4 sprays the spray material on the ground to achieve marking. When spraying, the vacuum pump 71 works, and the suction hood 73 generates negative pressure. The negative pressure sucks away the dust and sand and gravel particles on the spraying track, and discharges them to the other side of the cold spray marking machine body 1 through the connecting pipe 74 and the air injection pipe 72, so as to ensure the smoothness of the ground spraying surface and improve the quality of spraying.

[0023] In a further preferred embodiment of the present invention, Figure 1-2 and Figure 4 As shown, an air suction pump 71 in a dust cleaning assembly 7 is fixedly connected to an outer wall of one side of a cold spray marking machine body 1 by bolts, an air jet pipe 72 is fixedly connected to the output end of the air suction pump 71 by bolts, an air suction hood 73 is fixedly connected to the bottom of the nozzle fixing frame 3 at a position close to the marking nozzle 4 by bolts, and a connecting pipe 74 is fixedly connected between the air suction hood 73 and the air inlet end of the air suction pump 71 by bolts.

[0024] In this embodiment, dust and sand and gravel particles are removed from the ground along the spraying line by the dust cleaning component 7, so as to ensure the smoothness of the spraying surface of the ground and improve the quality of the spraying.

[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the cross-section of the nozzle fixing bracket 3 is a "cross" shaped structure, and grooves are provided at the bottom of the nozzle fixing bracket 3 near the outer sides of the first ball screw 61 and the second ball screw 62; the screw threads on the first ball screw 61 and the second ball screw 62 have opposite rotation directions, and the nut seats of the first ball screw 61 and the second ball screw 62 are fixedly connected to the two baffles 64 through nuts, and the two baffles 64 are perpendicular to the ground.

[0026] In this embodiment, the grooves are arranged to ensure smooth rotation of the first ball screw 61 and the second ball screw 62, and the two baffles 64 can be moved toward or away from each other by screws with opposite threads, thereby adaptively adjusting according to the width of the spray line.

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 4As shown, one end of the spray pipe 5 is inserted into the material barrel in the cold spray marking machine body 1, and the spray pipe 5 is provided with pneumatic pressure by the air compressor in the cold spray marking machine body 1, and the marking nozzle 4 and the spray pipe 5 are connected; the air hood 73 and the connecting pipe 74 are connected, and the bottom cross-section of the air suction hood 73 is a circular structure.

[0028] In this embodiment, the spray material is provided for spray marking through a material barrel, and the pneumatic pressure is provided by an air compressor to realize cold spraying.
