Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0018] like Figure 1-Figure 5As shown, a road marking equipment for construction engineering comprises a cart 1, a rotating shaft 101 is rotatably connected to the rear side of the bottom of the bottom plate of the cart 1, rollers are connected to both ends of the rotating shaft 101, a universal wheel is connected to the front side of the bottom of the bottom plate of the cart 1, a storage tank 2 is fixedly connected to the rear side of the top of the bottom plate of the cart 1, a pump 3 is installed on the top of the bottom plate of the cart 1, the input end of the pump 3 is connected to the bottom of the storage tank 2 through a connecting pipe, the input end of the pump 3 is connected to a connector 4 through a connecting pipe, a spray gun 5 is detachably connected to the connector 4, and the spray gun 5 can be replaced according to the marking width requirement, a through hole 102 for the spray gun 5 to pass through is opened at the front part of the bottom plate of the cart 1, a limit plate 12 is fixedly connected to the connector 4, a card slot 103 matching the limit plate 12 is opened on the bottom plate of the cart 1, a line plate 9 is slidably connected to the bottom of the bottom plate of the cart 1 left and right, and an adjustment component for adjusting the distance between the two line plates 9 is provided at the bottom of the bottom plate of the cart 1.

[0019] A stirring rod 6 is rotatably connected inside the storage tank 2. The lower end of the stirring rod 6 rotates and passes through the bottom of the storage tank 2 and the bottom plate of the cart 1, and is fixedly connected to a worm gear 7. A worm 8 is provided in the middle of the rotating shaft 101, and the worm 8 is meshed with the worm gear 7. When the cart 1 moves, the roller drives the rotating shaft 101 to rotate, and then drives the worm gear 7 and the stirring rod 6 to rotate through the worm 8, thereby realizing the stirring function of the stirring rod 6 and effectively preventing the precipitation of the marking material.

[0020] The adjustment component includes a bidirectional screw rod 10, which is rotatably connected to the bottom of the base plate of the cart 1. The two alignment plates 9 are respectively threadedly connected to the two threaded sections of the bidirectional screw rod 10. A hand-cranked turntable 11 is fixedly connected to one end of the bidirectional screw rod 10. The bidirectional screw rod 10 is adjusted by the hand-cranked turntable 11, so that the spacing between the two alignment plates 9 can be flexibly adjusted to meet the marking requirements of different widths.

[0021] The limiting plate 12 is U-shaped, and two ends of the limiting plate 12 are slidably connected to two clamping columns 13. An elastic member 14 is connected between the clamping column 13 and the limiting plate 12. A clamping groove 104 matching the clamping column 13 is opened in the clamping groove 103. When the connecting head 4 is inserted into the clamping groove 103, the clamping column 13 is clamped into the clamping groove 104 under the elastic action of the elastic member 14, thereby maintaining the stability of the connecting head 4 and the spray gun 5.

[0022] The left and right ends of the through opening 102 are rotatably connected with baffle plates 15, and the two baffle plates 15 are provided with movable grooves for the connecting head 4 to pass through. The bottom plate of the cart 1 is provided with limiting grooves 105 matching the baffle plates 15, and the front and rear sides of the two alignment plates 9 are fixedly connected with baffle plates 16. The two baffle plates 16 belonging to the two alignment plates 9 and on the same side are staggered. The design of baffle plates 15 and baffle plates 16 can form a relatively closed space for the spraying operation of the spray gun 5, thereby reducing the risk of spray overflow.

[0023] A transparent window 17 is provided in the storage tank 2 to facilitate observation of the remaining amount of the marking material and timely replenishment.

[0024] Working principle: When in use, according to the requirements of the width of the marking, select a spray gun 5 of appropriate width to connect with the connector 4, rotate and open the two baffles 15, and move the spray gun 5 through the opening 102 by holding the connector 4, and then rotate the two baffles 15 in the opposite direction to close the opening 102, and then insert the limit plate 12 on the connector 4 into the card slot 103, and the card column 13 on the limit plate 12 is kept in the card slot 2 104 under the elastic action of the elastic member 14, so as to maintain the stability of the connector 4 and the spray gun 5, and then adjust the hand-cranked turntable 11. The bidirectional screw rod 10 is adjusted to make the spacing between the two alignment plates 9 match the width of the selected spray gun 5, and then the cart 1 is pushed to move along the predetermined route. At the same time, the pump 3 pumps the marking material to the spray gun 5 for spraying on the ground. The two alignment plates 9 and the baffle plate 16 thereon form a relatively closed space for the spray gun 5 to spray, which can reduce the risk of spray overflow. During the movement of the cart 1, the roller and the rotating shaft 101 rotate, so that the worm 8 on the rotating shaft 101 drives the worm wheel 7 and the stirring rod 6 to rotate, so as to achieve uniform stirring of the marking material and prevent precipitation.
