Referring to fig. 1 and 2, the scribing device for road construction includes a vehicle body 1, a paint bucket 31 is provided in the vehicle body 1, and a shower head 34 communicating with the paint bucket 31 is provided on a side of the vehicle body 1 close to a road surface. One end of the vehicle body 1 forward to the advancing direction is hinged with a push plate 21 with the bottom edge being flush with the road surface, and a driving mechanism for driving the bottom edge of the push plate 21 to abut against/be away from the road surface is arranged on the vehicle body 1.

When the road marking operation is performed, the vehicle body 1 advances, the paint in the paint bucket 31 is sprayed from the spray head 34 to the road surface, and at the same time, the push plate 21 pushes away the large foreign matter in front of the vehicle body 1. When the push plate 21 is abutted against the immovable protrusions on the road surface, the driving mechanism drives the bottom edge of the push plate 21 to be away from the road surface, and the push plate 21 can avoid the immovable protrusions on the road surface, so that the vehicle body 1 is not blocked from advancing, and the problem that the protrusions on the road surface prevent the vehicle body 1 from being inconvenient to feed and scribe is solved.

Referring to fig. 2, a connection pipe 32 is connected to the paint bucket 31, the connection pipe 32 extends to a side of the vehicle body 1 near the road surface and is connected to a spray head 34, and a solenoid valve 33 is mounted to the connection pipe 32. In the present embodiment, there are a plurality of the spray heads 34, and the direction of arrangement of the plurality of spray heads 34 is orthogonal to the direction in which the vehicle body 1 advances.

In the course of the road marking operation, the paint in the paint bucket 31 passes through the connecting pipe 32, and when the electromagnetic valve 33 is opened, the paint is released and sprayed to the road surface through the spray head 34, and mark lines are marked on the road surface along with the advancing of the vehicle body 1; when the solenoid valve 33 is closed, paint is not ejected from the ejection head 34.

Referring to fig. 1, a support frame 22 is hinged on a vehicle body 1, a support rod 23 is fixedly connected to one side of the support frame 22 away from the vehicle body 1, one end of the support rod 23 away from the vehicle body 1 is fixedly connected with a push plate 21, and a driving mechanism is used for driving the support frame 22 to turn over in a direction approaching/separating from a road surface. Specifically, the driving mechanism comprises an electric push rod 26 arranged on the vehicle body 1, a cylinder body of the electric push rod 26 is hinged on the vehicle body 1, and a piston rod is hinged on the support frame 22.

Further, referring to fig. 3, the support rod 23 includes a main rod 231 and a sub rod 232 which are slidably coupled, one end of the main rod 231 near the push plate 21 is provided with a receiving groove 233 into which the sub rod 232 is inserted, and a control mechanism for sensing the push plate 21 abutting against an obstacle and driving the piston rod of the electric push rod 26 to retract/extend is provided in the receiving groove 233.

Specifically, referring to fig. 3, the control mechanism includes a pressure sensor 24 mounted on the bottom wall of the housing groove 233 and connected to the electric push rod 26 in a controlled manner, and a spring 25 fitted around the pressure sensor 24 is provided in the housing groove 233. One end of the spring 25 is fixedly connected to the main rod 231 in the accommodating groove 233, and the other end is fixedly connected to one end of the auxiliary rod 232 away from the push plate 21. The axial length of the spring 25 in the natural state is greater than the thickness of the pressure sensor 24 in the axial direction of the spring 25, and the axial length of the spring 25 when fully compressed is less than the thickness of the pressure sensor 24 in the axial direction of the spring 25.

In the process of advancing the vehicle body 1, the push plate 21 pushes the large sundries on the road surface, the pressure of the sundries on the push plate 21 drives the auxiliary rod 232 to slide in the accommodating groove 233 towards the direction of the vehicle body 1, and at the moment, the compression deformation of the spring 25 is insufficient to enable the end part of the auxiliary rod 232 to abut against the pressure sensor 24, so that the piston rod of the electric push rod 26 does not move.

When the push plate 21 abuts against the immovable protrusions on the road surface, the pressure applied to the push plate 21 increases, the auxiliary rod 232 continues to compress the spring 25 until the end of the auxiliary rod 232 abuts against the pressure sensor 24, and at the moment, the electric push rod 26 in control connection with the pressure sensor 24 retracts to drive the support frame 22 to overturn in a direction away from the road surface, so that the bottom edge of the push plate 21 is driven to be away from the road surface.

After the bottom edge of the push plate 21 is far away from the road surface, the push plate 21 is not stressed, the spring 25 is reset under the action of deformation force, the stress stressed by the pressure sensor 24 becomes zero, and at the moment, the electric push rod 26 in control connection with the pressure sensor 24 extends out of the piston rod of the electric push rod, so that the support frame 22 is driven to overturn towards the direction close to the road surface, and the bottom edge of the push plate 21 is driven to be abutted against the road surface.

Specifically, the bottom edge of the push plate 21 is integrally formed with a convex portion along its contour, and the wear-resistant strip 27 is a rubber sleeve wrapped on the convex portion.

The wear resistance of the bottom edge of the push plate 21 is improved by the wear-resistant strips 27, and as the wear-resistant strips 27 are clamped at the bottom end of the push plate 21, when the wear-resistant strips 27 are worn, the wear-resistant strips 27 can be replaced, so that the situation of excessive wear of the bottom edge of the push plate 21 is reduced.

Referring to fig. 2, an exhaust fan 41 is installed in the vehicle body 1, an air inlet 42 communicated with an air inlet end of the exhaust fan 41 is formed in the bottom of the vehicle body 1, the air inlet 42 is located at one side of the vehicle body 1 close to the push plate 21, an air outlet end of the exhaust fan 41 is communicated with a glove box 43, and an air inlet cover 44 is fixedly connected at the air inlet 42 at one side of the vehicle body 1 close to a road surface.

During the forward movement of the vehicle body 1, light impurities and dust which are not pushed away by the push plate 21 on the road surface are pumped into the impurity box 43 by the exhaust fan 41 through the air inlet cover 44, so that the influence of the impurities and dust on the road surface scribing work is reduced.

Further, referring to fig. 2, a blower 51 is further installed in the vehicle body 1, an air outlet 52 communicating with the air outlet end of the blower 51 is provided at the bottom of the vehicle body 1, the air outlet 52 is located at one side of the vehicle body 1 away from the push plate 21, and an air outlet cover 54 is fixedly connected at the air outlet 52 at one side of the vehicle body 1 close to the road surface.
