One side of the pair of mud scraping plates 502-4 away from the water hanging plate 502-3 contacts the upper and lower sides of the tape measure belt respectively. A water leakage groove 502-5 is provided on one side of the pair of mud scraping plates 502-4 close to the wiper blade 502-3. In the above, by providing the mud scraping plate 502-4, stubborn mud and dirt attached to the tape measure belt can be effectively scraped off, improving the cleaning effect.

[0067] In summary, when the tape measure belt is wound up, the driving motor 202-2, the water pump 501-3 and the hot air circulation system 402 are started. When the driving motor 202-2 runs, it drives the worm 202-3 to rotate, and the worm 202-3 drives the winding shaft 203 to rotate and wind up. The winding is limited by a pair of limit discs 204. During the winding process, when the water pump 501-3 runs, the water in the water storage tank 501-9 is introduced into the L-shaped water delivery pipe 501-4, then enters the C-shaped pipe 501-5 from the L-shaped water delivery pipe 501-4, and finally is sprayed onto the upper and lower surfaces of the tape measure belt by the nozzle 501-6 to achieve the effect of removing surface mud and loose dirt. After the tape measure belt is sprayed and rinsed, the stubborn mud and dirt on the upper and lower surfaces of the tape measure belt are scraped off by the obliquely arranged mud scraping plate 502-4, and then the water on the tape measure belt is scraped off by the wiper blade 502-3. After that, the tape measure belt enters the drying box 401 and is dried by the hot air circulation system. After drying, it is wound up by the winding shaft 203 between the two guide rollers 302.

The difference between this embodiment and the first embodiment is that the cleaning unit 500 further includes a linkage cleaning mechanism 503, which is connected to the winding and releasing unit 200, the spraying and rinsing mechanism 501 and the driving mechanism 202, and is used to intermittently wash the scraping mechanism 501.

[0070] Specifically, as Figure 7-8, the linkage cleaning mechanism 503 includes a connecting pipe 503-1 fixedly communicated with the U-shaped pipe 501-5. One end of the connecting pipe 503-1 away from the U-shaped pipe 501-5 is fixedly communicated with an opening and closing pipe 503-2. A first stabilizing plate is fixedly connected to the opening and closing pipe 503-2, and the first stabilizing plate is fixedly connected to the water storage tank 501-9 for fixing the opening and closing pipe 503-2. A fixed disk 503-3 is hermetically fixed inside the opening and closing pipe 503-2. A first water passing port 503-4 is opened near the edge of the fixed disk 503-3.

The movable disk 503-5 is hermetically and movably attached to the fixed disk 503-3. A second water passing port 503-6 is opened near the edge of the movable disk 503-5. During the rotation of the movable disk 503-5, the second water passing port 503-6 can intersect with the first water passing port 503-4. When they intersect, water flow can be delivered to the side of the movable disk 503-5 away from the fixed disk 503-3;

[0071] A connecting column 503-7 is fixedly connected to the center of the side of the movable disk 503-5 away from the fixed disk 503-3. One end of the connecting column 503-7 away from the movable disk 503-5 is fixedly connected to a rotating shaft 503-8. A second stabilizing plate is rotatably connected to the rotating shaft 503-8 through a bearing, and the second stabilizing plate is fixedly connected to the water storage tank 501-9 for stabilizing the rotating shaft 503-8 so that it can rotate smoothly. The rotating shaft 503-8 is hermetically and rotatably connected to the inside of the end of the opening and closing pipe 503-2 away from the connecting pipe 503-1. A first gear 503-9 is fixedly connected to the outer end of the rotating shaft 503-8. A linkage driving assembly 503-10 is connected to the top of the first gear 503-9, and the linkage driving assembly 503-10 is connected to the worm 202-3 for driving the first gear 503-9 to rotate;

[0072] As Figure 7 , a T-shaped pipe 503-11 is fixedly communicated with the side of the opening and closing pipe 503-2 facing the sludge scraping plate 502-4. Flushing nozzles 503-12 are fixedly communicated with both the upper and lower ends of the T-shaped pipe 503-11. A pair of the flushing nozzles 503-12 respectively correspond to the sides of a pair of sludge scraping plates 502-4 away from the tape. The diameter of the connecting column 503-7 is smaller than the inner diameter of the opening and closing pipe 503-2. The T-shaped pipe 503-11 is located between the movable disk 503-5 and the rotating shaft 503-8.

[0073] Furthermore, as Fig. 9, the linkage drive assembly 503-10 includes a second gear 503-101 meshingly connected to the top of the first gear 503-9 and a worm wheel 503-105 meshingly connected to the bottom of the worm 202-3;

[0074] A first connecting shaft 503-102 is fixedly connected at the center of the second gear 503-101, a third stabilizing plate 503-103 is rotatably mounted on one end of the first connecting shaft 503-102 away from the second gear 503-101, the third stabilizing plate 503-103 is fixedly connected to the water tank 501-9, and a first pulley 503-104 is fixedly sleeved on the first connecting shaft 503-102;

[0075] A second connecting shaft 503-106 is fixedly connected at the center of the worm wheel 503-105, and a fourth stabilizing plate 503-107 is rotatably installed on the end of the second connecting shaft 503-106 away from the worm wheel 503-105. A second pulley 503-108 is fixedly sleeved on the second connecting shaft 503-106 at a position corresponding to the first pulley 503-104. The second pulley 503-108 is connected to the first pulley 503-104 through a belt 503-109. A fifth stabilizing plate is rotatably sleeved on the second connecting shaft 503-106, and the fifth stabilizing plate is fixedly connected to the first fixed plate 201.

[0076] The remaining structures are the same as those of Example 1.

[0077] In summary, during the winding process, the worm 202-3 drives the worm wheel 503-105 to rotate, the worm wheel 503-105 rotates through the second connecting shaft 503-106, the second connecting shaft 503-106 drives the second pulley 503-108 to rotate, the second pulley 503-108 drives the first pulley 503-104 to rotate through the belt 503-109, the first pulley 503-104 drives the first connecting shaft 503-102 to rotate, the first connecting shaft 503-102 drives the second gear 503-101 fixedly connected thereto to rotate, the second gear 503-101 drives the first gear 503-9 meshing with it at the bottom to rotate. 03-9 drives the connecting column 503-7 to rotate through the rotating shaft 503-8, and the connecting column 503-7 drives the movable disk 503-5 to rotate. When the second water port 503-6 on the movable disk 503-5 intersects with the first water port 503-4 on the fixed disk 503-3, the water flow in the opening and closing pipe 503-2 on the fixed disk 503-3 toward the connecting pipe 503-1 side can enter the side of the movable disk 503-5 away from the fixed disk 503-3 through the intersection, and then enter the flushing gun head 503-12, and is sprayed toward the scraper plate 502-4 by the flushing gun head 503-12, which can flush away the accumulated mud on the scraper plate 502-4, and prevent the accumulated mud from affecting the scraping effect of the scraper plate 502-4. When the second water opening 503-6 on the movable disk 503-5 does not intersect with the first water opening 503-4 on the fixed disk 503-3, the flushing stops, and the scraper 502-4 can be flushed at regular intervals during the continuous rotation of the movable disk 503-5, thereby ensuring the scraping effect of the scraper 502-4. In addition, if the measuring tape is released, the water pump 501-3 does not run, so the flushing gun head 503-12 will not spray water, thereby not causing a waste of water resources.

[0078] The measurement method using the above land planning area measurement device is as follows: When winding the tape, start the drive motor 202-2, the water pump 501-3, and the hot air circulation system 402. When the drive motor 202-2 operates, it drives the worm 202-3 to rotate, and the worm 202-3 drives the winding shaft 203 to rotate and wind. The winding is limited by a pair of limit disks 204. During the winding process, when the water pump 501-3 operates, it introduces the water in the water storage tank 501-9 into the L-shaped water supply pipe 501-4, then enters the U-shaped pipe 501-5 from the L-shaped water supply pipe 501-4, and finally sprays onto the upper and lower surfaces of the tape through the nozzle 501-6 to achieve the effect of removing surface soil and loose dirt. After the tape is sprayed and rinsed, the stubborn soil and dirt on the upper and lower surfaces of the tape are scraped off by the inclined mud scraping plate 502-4, and then the water on the tape is scraped off by the water scraping plate 502-3. After that, the tape enters the drying box 401 and is dried by the hot air circulation system. After drying, it is wound by the winding shaft 203 between the two guide rollers 302. During the winding process, the worm 202-3 simultaneously drives the worm gear 503-105 to rotate. The worm gear 503-105 rotates through the second connecting shaft 503-106, and the second connecting shaft 503-106 drives the second pulley 503-108 to rotate. The second pulley 503-108 drives the first pulley 503-104 to rotate through the belt 503-109. The first pulley 503-104 drives the first connecting shaft 503-102 to rotate. The first connecting shaft 503-102 drives the second gear 503-101 fixedly connected thereto to rotate. The second gear 503-101 drives the first gear 503-9 meshed with its bottom to rotate. The first gear 503-9 drives the connecting column 503-7 to rotate through the rotating shaft 503-8. The connecting column 503-7 drives the movable disk 503-5 to rotate. When the second water passing port 503-6 on the movable disk 503-5 intersects with the first water passing port 503-4 on the fixed disk 503-3, the water flow in the opening and closing pipe 503-2 on the side of the fixed disk 503-3 facing the connecting pipe 503-1 can enter the side of the movable disk 503-5 away from the fixed disk 503-3 through the intersection, and then enter the flushing gun head 503-12. It is sprayed from the flushing gun head 503-12 onto the mud scraping plate 502-4, which can wash away the accumulated mud on the mud scraping plate 502-4 and prevent the accumulated mud from affecting the scraping effect of the mud scraping plate 502-4. When the second water passing port 503-6 on the movable disk 503-5 does not intersect with the first water passing port 503-4 on the fixed disk 503-3, the flushing stops. During the continuous rotation of the movable disk 503-5, the mud scraping plate 502-4 can be flushed at regular intervals, rather than continuously flushing the mud scraping plate 502-4, which can save water resources.

[0079] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
