As a further optimization of the present embodiment, as shown in fig. 3, the opening 3 extends along the width direction of the moving platform 2, and the paint spraying mechanism includes: an outer cylinder 5 fixed in the moving platform 2 and extending along the width direction of the moving platform 2, wherein a material conveying pipe 6 is communicated with the outer cylinder 5, and one end of the material conveying pipe 6, far away from the outer cylinder 5, is communicated with the bottom of the paint storage box 1;
The lower part of urceolus 5 is arc structure, as shown in fig. 6, urceolus 5 internal rotation is connected with a cylinder pole 7, cylinder pole 7 and the arcwall face contact of urceolus 5, be equipped with on the arcwall face along urceolus 5 axial extension's bar hole 8, be equipped with a plurality of bar recess 9 on the outer wall of cylinder pole 7, each bar recess 9 extends and all bar recess 9 are equidistant along the circumference of cylinder pole 7.
In this embodiment, the feed conveyor pipe 6 is a PVC hose. In the arrangement of the strip-shaped groove 9 on the cylindrical rod 7 in the embodiment, after the paint is injected into the outer cylinder 5 through the feed conveying pipe 6, the strip-shaped groove 9 on the arc is in a sealing state because the bottom of the cylindrical rod 7 and the bottom of the outer cylinder 5 are in the same arc shape; in the process of rotating the cylindrical rod 7, a certain amount of paint can be filled in the strip-shaped groove 9, and when the strip-shaped groove 9 rotates to the strip hole 8, the paint is discharged from the strip hole 8 and can fall onto the target ground; therefore, in the rotating process of the cylinder, the coating is loaded and unloaded, and the unloading convenience is improved; the strip-shaped grooves 9 of the present embodiment are typically provided with six; next, in order to allow the paint in the paint storage tank 1 to normally and automatically flow into the outer tube 5, the outer tube 5 is not completely sealed, and a water-blocking and air-permeable film (the water-blocking and air-permeable film is a conventional technology in the art, and is not shown in the drawings) is provided on the top of the outer tube 5.
In this embodiment, since the mobile platform 2 can be dragged and moved by the constructor, the moving speed of the mobile platform 2 is not uniform; in addition, in the case of remote control, the speed of the mobile platform 2 may be uneven, and the amount of discharged material needs to be dynamically adjusted along with the change of the moving speed. In this embodiment, the transmission shaft of the cylindrical rod 7 is connected with the wheel transmission of the mobile platform 2, and the transmission structure adopts sprocket transmission, that is, a first sprocket 38 is arranged on the transmission shaft of the cylindrical rod 7, a second sprocket is also arranged on the axle of the mobile platform 2, and the first sprocket 38 and the second sprocket are connected through a chain (the transmission structure is not shown in the drawing). Therefore, when the moving platform 2 moves, the rotation of the wheels drives the second sprocket wheel to rotate, and simultaneously drives the first sprocket wheel 38 to rotate, so that the rotation of the cylindrical rod 7 is realized; at this time, the cylindrical rod 7 and the wheels keep rotating synchronously, when the moving speed of the moving platform 2 increases, the rotating speed of the cylindrical rod 7 also increases, the frequency of the coating material loading and unloading of the strip-shaped groove 9 increases, and the amount of the coating material discharged per unit time also increases; when the moving speed of the moving platform 2 is reduced, the rotating speed of the cylindrical rod 7 is also reduced, the frequency of the coating material loading and unloading of the strip-shaped groove 9 is reduced, and the amount of the coating material discharged per unit time is also reduced; the paint spraying mechanism of the present embodiment is therefore capable of adaptively adjusting the amount of paint discharged with the moving speed; the amount of the discharged paint is small under the condition that the moving speed of the moving platform 2 is not uniform, so that the influence on the uneven scraping and coating of the target ground paint can be avoided.
As a further optimization of this embodiment, since the amount of material taken in each time of the strip-shaped groove 9 is constant, the blade coating thickness requirements of a part of the target ground are not consistent, and the rotation of the cylindrical rod 7 is consistent with the wheel; at this time, it is necessary to adjust the amount of discharged material according to the amount actually required for the thickness of the blade coating, that is, to adjust the volume of the bar-shaped groove 9 for loading and unloading the coating.
