Car, driven using the rotation of preceding runner and be stained with paint device, the hairbrush bar being stained with paint device rolls after being stained with paint, by the even paint of centre
Device rotates uniformly to stick on preceding runner paint and directly bear against and completes to rule on the ground.It is exactly to pass through wheel shaft in general
Rotate and drive line mutually, the even paint apparatus surface of use is the strong brush special bar of adsorptivity, and can be changed.Whole line
As long as process one man operation, convenient and simple, time saving and energy saving.
The application for a patent for invention of Application No. 201511035160.0 for another example, it is entitled《A kind of pen machine》, retouch
What is stated is exactly that a kind of paint is sprayed to the example on ground, the invention by nozzle provides a kind of pen machine, including car body, also
Including range line chi, one end of the range line chi is fixed on the car body, and the other end of the range line chi is provided with wheel, also wraps

Due to that using above-mentioned technical proposal, the distance of drawn line and other objects of reference can be accurately defined by range line chi, operates letter
It is single, it is time saving and energy saving.
The line that the line-marking vehicle of both the above type is done all has a disadvantage that, that is, does the edge wheel profile rule not
Neatly, this is that the profile of straight line forms serpentine bending sometimes, unintelligible, very unsightly, and falls in play still boundary on ball
It is outer sometimes indefinite, easily produce dispute.
Such as the former runner-driven ruling car, gravity is bigger when filling paint in railway carriage, and preceding runner stress is larger, hair
The degree of raw elastic deformation is larger, and the line made on the ground is relatively thick heavier；With the progress of line, the paint in railway carriage is got over
Come fewer, weight is more and more lighter, and preceding runner stress is less and less, occurs that the degree of elastic deformation is smaller, and that does on the ground draws
Line is relatively thin lighter.Further, operator applies thrust by car bar to line-marking vehicle, and thrust is unlikely to be uniform, small when big when understanding,
The line done when thrust is bigger is relatively thick heavier, and the line done when thrust ratio is smaller is relatively thin lighter.In a word, this line-marking vehicle
Line thickness, the weight done are uneven.
The nozzle-type line-marking vehicle of the latter for another example, the underface of nozzle is often sprayed denseer heavier, then sprays oily toward surrounding
Paint just tails off, and sprays thin relatively light, so the scribing edge profile that this line-marking vehicle is done is unsharp, scribing edge and line
Middle part often has a paint vehicle by light to dense intermediate zone.
What regional area sprayed sometimes is more, paints and is trickled to low-lying place, flows to beyond scribe area, cause contour line to fail to understand
Really.
The lines so generated, edge is uneven, very unsightly.
It is to go back in play in play if shuttlecock just falls on intermediate zone border if being divided into shuttlecock place
It is indefinite in out-of-bounds standard, often produces dispute, judge can not clearly adjudicates.
