[0023] like Figure 1 and Figure 3 As shown, this embodiment proposes a line-drawing device for land planning surveying, including a base plate 1, a hopper 2 bolted to the top of the base plate 1, a material spreading component 3 for uniformly spreading material inside the hopper 2, a moisture-proof component 4 for preventing lime from getting damp and clumping at the top of the hopper 2, a moving component 5 for moving this device for land planning surveying at the bottom of the base plate 1, a control component 6 for controlling the material spreading component 3 at the top of the base plate 1, and a gripping component 7 for facilitating measurement by workers on one side of the hopper 2. like Figure 4 and Figure 5 As shown, the uniform material spreading component 3 includes a servo motor 301 fixedly installed on the bottom of the base plate 1. A rotating roller 302 is installed at the output end of the servo motor 301. The rotating roller 302 passes through the ash hopper 2 and is connected to the bearing of the ash hopper 2. Multiple sets of stiff bristles 303 are fixedly connected to the rotating shaft. Driven by the servo motor 301, the roller 302 stirs and agitates the lime during rotation. The multiple sets of stiff bristles 303 are evenly distributed around the circumference of the roller 302. In use, lime is poured into the ash hopper 2 from the top, and the servo motor 301 is started. The servo motor 301 drives the roller 302 to rotate. The multiple sets of stiff bristles 303 come into contact with the lime and stir and agitate it during rotation, effectively preventing local accumulation or uneven distribution of lime during spreading. At the same time, the speed at which the lime falls can be controlled by adjusting the servo motor 301 to adapt to different line drawing speed requirements, making it easy to use.

[0024] like Figure 5As shown, the moisture-proof component 4 includes a cover plate 401 rotatably connected to the top of the ash hopper 2. A storage box 402 is provided on one side of the cover plate 401. The storage box 402 passes through the cover plate 401 and is fixedly connected to the cover plate 401 by bolts. An opening and closing door 403 is connected to the top of the storage box 402, and multiple sets of grooves are formed on the side wall of the storage box 402. In use, desiccant can be placed in the storage box 402 to absorb moisture and reduce the problem of lime caking in the ash hopper 2 due to moisture. When the desiccant is saturated with moisture, simply open the opening and closing door 403, take out the old desiccant, and put in new desiccant. There is no need to perform complicated disassembly or modification of the ash hopper 2, saving time and labor costs.

[0025] like Figure 4 As shown, the movable component 5 includes small wheels 501 that are bolted to the bottom of the base plate 1. A connecting rod 502 is bolted to the bottom of the base plate 1, and large wheels 503 are threaded to both ends of the connecting rod 502. The large wheels 503 are located on one side of the base plate 1. In use, the device can be easily moved using the small wheels 501 and the large wheels 503, facilitating land planning surveys.

[0026] like Figure 2 As shown, the control component 6 includes a control module 601 bolted to the top of the base plate 1. A display panel 602 is bolted to the control module 601. Multiple operation buttons 603 are provided at the bottom of the display panel 602. When in use, the operator can adjust the rotation speed of the servo motor 301 through the control module 601, thereby adjusting the speed at which the white powder falls to meet the needs of measurement and line drawing.

[0027] like Figure 5 As shown, the grip assembly 7 includes a telescopic rod 701 bolted to the top of the base plate 1. A crossbar 702 is fixedly connected to the top of the telescopic rod 701. Handles 703 are fixedly installed at both ends of the crossbar 702. When in use, the operator can hold the handles 703 and push the device to perform measurement and line drawing work.

[0028] like Figure 1 As shown, a lighting lamp 8 is bolted to the top of the base plate 1. There are two sets of lighting lamps 8, which are symmetrically arranged. When the ambient light is dim, the lighting lamps 8 can be turned on, which facilitates measurement and line drawing operations in dimly lit environments.

[0029] like Figure 1 As shown, three sets of reinforcing ribs 9 are welded to the outside of the ash hopper 2. The bottom of the three sets of reinforcing ribs 9 is welded to the top of the base plate 1. The three sets of reinforcing ribs 9 welded together improve the structural strength of the ash hopper 2, enabling it to bear more lime and meet the requirements for marking lines.

[0030] Specifically, when using the land planning surveying line marking device: such as Figure 4 and Figure 5 As shown, quicklime is poured into the ash hopper 2 from the top. The servo motor 301 is then started, driving the rotating roller 302 to rotate. Multiple sets of stiff bristles 303 contact the quicklime, stirring and agitating it during rotation. This effectively prevents localized accumulation or uneven distribution of the quicklime during spreading. The control module 601 adjusts the rotation speed of the servo motor 301, thereby adjusting the speed at which the quicklime falls to meet the needs of measurement and line marking. Figure 5 As shown, a desiccant can be placed in the storage box 402 to absorb moisture and reduce the problem of lime caking in the ash hopper 2 due to moisture. When the desiccant is saturated with moisture, simply open the door 403, take out the old desiccant, and put in the new desiccant. There is no need to disassemble or modify the ash hopper 2, saving time and labor costs. The staff can hold the handle 703 to push this device to carry out measurement and marking work. The lighting 8 can be turned on to facilitate measurement and marking work in a dimly lit environment.
