Gap spray coating device and road marking machine comprising same

Abstract

The invention discloses a gap spray coating device. The gap spray coating device comprises a driving wheel, a speed reducer, a left guide pipe and a rotary pipe, wherein one end of the driving wheel is connected with a bottom plate, and the other end of the driving wheel is provided with a first belt pulley; the speed reducer is arranged on the bottom plate, and the power input end of the speed reducer is provided with a second belt pulley; the second belt pulley and the first belt pulley are sleeved with a driving belt; the power output end of the speed reducer is connected with a speed reduction wheel; the left guide pipe communicates with a right guide pipe; the rotary pipe is arranged between the left guide pipe and the right guide pipe. Through arrangement of the driving wheel, the gap spray coating device records the moving distance of a road marking machine and transmits the moving distance to the speed reducer. The speed reducer drives the rotary pipe to rotate, so that the rotary pipe communicates with the left guide pipe and the right guide pipe at a full line to implement spray coating on the marking line and closes the left guide pipe and the right guide pipe at a dotted line to stop marking coating. There is no need to manually and repeatedly place markers and turn on and turn off a valve. The labor intensity is greatly reduced. The spray coating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of marking machine equipment, in particular to a gap spraying device and a road marking machine thereof. Background technique [0002] Traffic markings refer to signs that convey traffic information such as guidance, restrictions, and warnings to traffic participants on the road surface with lines, arrows, text, facade marks, raised road signs, and contour marks. Its function is to control and guide traffic, and it can be used in conjunction with signs or alone. Because traffic marking plays a very important role in traffic safety, there are high requirements for its performance, and the marking operation is generally carried out by a special marking machine.

Problems solved by technology

[0003] For the standard painting of lane boundaries in urban roads, since it is composed of dotted lines, the solid line is 2 meters long and the interval is 4 meters, workers first need to continuously place markers at the starting point and end point of the solid line; During the process, the workers who operate the marking machine need to continuously open the marking machine valve at the starting point of the solid line, and close the marking machine valve at the end point of the solid line. Repeatedly, the operation is cumbersome and labor-intensive. low efficiency
