[0028] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0029] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides a road marking device for road planning and construction, including a tank body 4, a discharge pipe 15, a brush holder 12, an air drying system 14, and a cart;

[0032] The cart includes a bottom plate 1, a push plate 2 is fixed on the bottom plate 1, and a handle 3 is fixed on the push plate 2. The handle 3 is provided to facilitate the staff to manually push the bottom plate 1. The tank body 4 is used to store powder. The tank body 4 is fixedly mounted on the bottom plate 1 through a bracket. The top end of the discharge pipe 15 is connected to the bottom outlet of the tank body 4. The bottom end of the discharge pipe 15 passes downward through the bottom plate 1 and is fixed to the brush holder 12. The discharge pipe 15 is connected to the inside of the brush holder 12. A horizontal brush roller 13 is installed in the brush holder 12. The brush roller 13 is in contact with the ground so that the brush roller 13 can roll along the ground. A discharge valve 16 is provided on the discharge pipe 15. The bottom of the tank body 4 can be a funnel-shaped structure, which is conducive to the powder in the tank body 4 being concentrated to the bottom. After the discharge valve 16 is opened, the powder in the tank 4 can enter the brush holder 12 through the discharge pipe 15 due to gravity, and then flow to the brush roller 13. Then, by pushing the cart, the bottom plate 1 moves forward and backward, and the brush roller 13 can roll the powder onto the ground, thus completing the road marking operation.

[0033] In order to speed up the drying of the powder, in this embodiment, the air drying system 14 includes a box body 1401 and a rotating mechanism. The box body 1401 is fixed to the bottom of the bottom plate 1, and the box body 1401 is located behind the brush holder 12. The bottom plate of the box body 1401 is penetrated with a first through hole, and a first rotating shaft 1403 is rotatably inserted in the first through hole. A fan blade 1404 is fixed on the side wall of the first rotating shaft 1403, and the fan blade 1404 is located below the box body 1401. The rotating mechanism is used to drive the first rotating shaft 1403 to rotate. When the rotating mechanism drives the first rotating shaft 1403 to rotate, it can drive the fan blade 1404 to rotate, similar to the function of a fan, to sweep the bottom, so that when the bottom plate 1 is pushed to draw a line, the fan blade 1404 can sweep the area behind the line, thereby speeding up the drying of the powder.

[0034] In some embodiments, the rotating mechanism may include an air-drying motor, which is fixed in the box body 1401, and the power output end of the air-drying motor is coaxially fixed with the first rotating shaft 1403. The air-drying motor can drive the first rotating shaft 1403 to rotate, thereby driving the fan blades 1404 to rotate, so as to achieve the blowing of the area below the box body 1401, which can accelerate the drying of the powder below.

[0035] In some embodiments, a connection seat 9 is fixed at each of the four corners of the bottom of the base plate 1, and a rotation hole is provided on the side wall of the connection seat 9. A connection shaft 10 is rotatably inserted in the rotation hole, and one connection shaft 10 simultaneously passes through the rotation holes of two connection seats 9. Moving wheels 11 are coaxially fixed at both ends of the connection shaft 10. When the base plate 1 is pushed to move, the moving wheels 11 roll along the ground, driving the connection shaft 10 to rotate.

[0036] Among them, Figure 3As shown, the rotating mechanism may include a second rotating shaft 1405, a first driven bevel gear 1406, a first active bevel gear 1407, a second active bevel gear 1408, and a second driven bevel gear 1409. The first active bevel gear 1407 is coaxially fixedly sleeved on the outside of the connecting shaft 10. A second through hole is opened on the side wall of the box body 1401. The second rotating shaft 1405 can be rotatably inserted in the second through hole. The first driven bevel gear 1406 is coaxially fixedly sleeved on the second rotating shaft 140 5, the first driven bevel gear 1406 is meshed with the first driving bevel gear 1407, the second driving bevel gear 1408 is coaxially fixedly sleeved on the outside of the second rotating shaft 1405, the second driven bevel gear 1409 is coaxially fixedly sleeved on the outside of the first rotating shaft 1403, the second driven bevel gear 1409 is meshed with the second driving bevel gear 1408, and the second driven bevel gear 1409 and the second driving bevel gear 1408 are both located in the box body 1401.

[0037] Based on the above structure, when the bottom plate 1 is pushed to move, the connecting shaft 10 rotates, and the first active bevel gear 1407 rotates synchronously, driving the first driven bevel gear 1406 to rotate, and then driving the second rotating shaft 1405 to rotate, and then driving the second active bevel gear 1408 to rotate, and then driving the second driven bevel gear 1409 to rotate, and finally driving the first rotating shaft 1403 to rotate, so that the area below the box body 1401 can be purged, and the drying of the powder below can be accelerated. When the bottom plate 1 stops being pushed, the first rotating shaft 1403 also stops rotating synchronously, thereby stopping the purging effect, without manual opening or closing, and the operation is more flexible and convenient. The outer side of the first rotating shaft 1403 can be sleeved with a bearing 1402, and the bearing 1402 is located between the second driven bevel gear 1409 and the bottom plate of the box body 1401, so that the first rotating shaft 1403 is more stable.

[0038] In order to prevent the powder in the tank 4 from settling, in this embodiment, Figure 2 , 4 As shown, the top end of the tank body 4 is covered with a cover plate 5, and a stirring motor 6 is installed on the top end of the cover plate 5. A stirring structure 8 is provided in the tank body 4, and the stirring structure 8 includes a stirring shaft 801. A stirring blade 802 is fixed on the side wall of the stirring shaft 801, and the top end of the stirring shaft 801 passes upward through the cover plate 5 and is coaxially fixed to the power output end of the stirring motor 6.

[0039] The stirring motor 6 can drive the stirring shaft 801 to rotate, thereby driving the stirring blade 802 to rotate, so as to stir and mix the powder in the tank body 4, thereby effectively preventing the powder in the tank body 4 from settling and causing poor line drawing effect in the later stage.

[0040] The cover plate 5 is provided with a feed port 7 through which materials can be directly fed into the tank body 4 .

[0041] A stirring hole 803 is provided on the stirring blade 802 near the stirring shaft 801. The provision of the stirring hole 803 can reduce the rotation resistance of the stirring blade 802, thereby improving the stirring efficiency.

[0042] Three stirring layers are arranged at intervals along the vertical direction on the side wall of the stirring shaft 801 , and each stirring layer includes four stirring blades 802 evenly spaced along the circumference of the stirring shaft 801 , so that the stirring effect is more uniform and the stirring efficiency is higher.

[0043] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.

[0044] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present utility model.
