In order to help construction workers quickly observe and construct in the designated area, workers need to use a lime marking vehicle to sprinkle lime on the ground in the area to complete the planning and restriction of the construction area, so as to facilitate the subsequent construction workers to work and avoid construction errors. For example, the existing public document CN114622466B-A lime marking vehicle with automatic feeding function for roadbed construction discloses a lime marking vehicle; Although the existing public white lime marking vehicle for municipal road construction can realize white lime marking, it still has certain shortcomings in actual use: first, the existing white lime marking vehicle directly spreads white lime through the ash hopper when in use, and this method is prone to the situation that the white lime is piled up after being spread, resulting in white lime waste, and requires manual subsequent processing to ensure that the white lime is flat, which is inefficient and increases the subsequent workload; secondly, the existing white lime marking vehicle spreads white lime onto the surface of the construction soil through a fixed ash spreading port when in use, and on the construction site, the white lime on the surface will be worn out by the long-term work of the construction personnel and the operation of the construction equipment, making it impossible to distinguish the white lime construction area, affecting normal construction; finally, the existing white lime marking vehicle is mostly used by manual observation to see whether the ash spreading line is a straight line, and this method has certain errors in the ash spreading process, affecting the ash spreading accuracy; therefore, it is necessary to improve the existing technology to solve the above technical problems.

When the lime on the surface of the construction area is worn, the marking position can continue to be observed and judged through the lime in the groove to ensure normal construction.

[0044] Furthermore, the electric push rod 401 is used to push the lifting gear plate 401a down. The lowering of the lifting gear plate 401a causes the third gear plates 402 on both sides to rotate synchronously, and drives the two groups of telescopic sleeves 403 to rotate under the action of the connecting rod 402b in the eccentric position, thereby adjusting the width of the marking position and increasing the practical range. Under the elastic performance of the second spring 405, the telescopic sleeve 403 is elastically moved to increase its telescopic range. Example 3

[0045] Reference Figure 1 , Fig.11 and Fig.12, which is the third embodiment of the present invention, is based on embodiment 1, except that, in order to ensure the linear accuracy of marking, the lime marking vehicle is moved along the marking line between the two counterweight seats 504 to assist the lime marking vehicle in linear movement.

[0046] Specifically, it also includes a bidirectional positioning assembly 500 arranged at the front and rear ends of the upper surface of the base 100, the bidirectional positioning assembly 500 includes a rope winding roller 501 rotatably arranged above the base 100 and a fourth rotating shaft 501a limitedly sleeved on the inner wall of the rope winding roller 501, the marking line on the outer wall of the rope winding roller 501 is connected to the front counterweight seat 504, one end of the fourth rotating shaft 501a is rotatably mounted in a bearing on the surface of the first fixed plate 502, and the other end of the fourth rotating shaft 501a is rotatably mounted in a bearing on the inner wall of the mounting groove 503a, and a pressure plate 501b is fixedly arranged at one end of the outer wall of the fourth rotating shaft 501a, and a coil spring 505 is compressed between the pressure plate 501b and the inner wall of the mounting groove 503a; wherein the mounting groove 503a is located above the outer wall of the second fixed plate 503, and the bottoms of the first fixed plate 502 and the second fixed plate 503 are both fixedly arranged on the surface of the base 100; When the above arrangement is in use, before using the lime marking vehicle, the counterweight seats 504 at the front and rear ends of the lime marking vehicle are pulled out and placed at the front and rear ends of the marking area. During the process of pulling the counterweight seat 504 outward, the rope winding roller 501 will be driven to rotate under the action of the marking line. The rotation of the rope winding roller 501 will drive the fourth rotating shaft 501a and the pressure plate 501b at its end to rotate, and will squeeze the coil spring 505. When the lime marking vehicle moves, it is necessary to add a certain weight to the counterweight seat 504 to ensure that the counterweight seat 504 remains stationary when the lime marking vehicle moves to spread lime. As the lime marking vehicle moves to spread lime, it can move in a straight line along the marking line, thereby improving the accuracy of the lime marking and reducing the probability of bending of the marking line.

[0047] Furthermore, weight can be added to the counterweight seat 504 as needed to ensure that the counterweight seat 504 can be stably placed on the ground when the lime marking vehicle moves. The pressure plate 501b cooperates with the inner wall of the installation groove 503a to squeeze the coil spring 505, and the elastic performance of the coil spring 505 can drive the rope winding roller 501 to rotate, thereby realizing automatic winding after the marking line is pulled out. Example 4

[0048] This embodiment is the fourth embodiment of the present invention, which provides a marking method for a lime marking vehicle for municipal road construction, specifically, comprising the following steps: S1: First, the construction personnel put the lime into the lime marking vehicle, grind and filter the lime, and then adjust the angles of the two sets of telescopic sleeves 403 at the bottom of the lime hopper 109 to complete the adjustment of the lime marking width; S2: Then pull the front and rear counterweight seats 504 and place them at the end of the marking position, and then lower them to change the height of the support plate 102 so that the ground contacting wheels 301 contact the ground; S3: Then, the first motor 201 is used to adjust the distance between the first opening and closing plate 204 and the second opening and closing plate 205 to complete the adjustment of the size of the feed opening; S4: Then, the lime in the storage box 103 is pumped out under the action of the pump body 107. At the same time, the construction personnel push the lime marking vehicle to move along the marking line between the two sets of counterweight seats 504; S5: During this process, the ground contact wheel 301 follows the movement and realizes the falling of the white ash and evenly shakes it onto the ground. Meanwhile, a small amount of white ash falls into the groove scraped out by the telescopic sleeve 403 along the telescopic sleeve 403, completing the marking operation.
