A handle 5 for conveniently pushing the device is welded to the rear part of the body 1, the rear part of the body 1 is rotatably connected to the mounting plate 6, the end of the mounting plate 6 away from the body 1 is installed with a paint sprayer 7 through a fixing piece, and the body 1 is symmetrically provided with a fixing mechanism for fixing the mounting plate 6.

[0020] like Figure 1 and Figure 2 As shown, the fixing mechanism includes a first guide block 8, a two-way inclined block 9 and a connecting spring 10. The rear part of the vehicle body 1 is connected to the first guide block 8, and the two-way inclined block 9 is slidably connected to the first guide block 8. The two-way inclined block 9 is symmetrically provided with inclined surfaces. The first guide block 8 and the two-way inclined block 9 are connected by a connecting spring 10 through a spring seat. When the mounting plate 6 is disconnected from the first guide block 8 on the other side, the first guide block 8 on the other side is reset to re-fix the mounting plate 6. At this time, the paint sprayer 7 is located on the other side of the device, thereby completing the position change operation of the paint sprayer 7, which enables the device to change the marking orientation of the device without moving the device itself.

[0021] Specifically, the bidirectional inclined block 9 includes a plate and a column, one end of the connecting spring 10 is connected to the lower surface of the first guide block 8, the other end of the connecting spring 10 is connected to the upper surface of the plate, one end of the column is connected to the upper surface of the plate, the other end of the column passes through the spring, the first guide block 8 and extends out of the upper surface of the vehicle body 1, and the inclined surface is symmetrically established on the part of the column extending out of the upper surface of the vehicle body 1.

[0022] like Figure 3As shown, it also includes a second guide block 11, a screw 12, a scraper 13 and a first turntable 14. The second guide block 11 is symmetrically connected to the bogie 4. The second guide block 11 is rotatably connected to the screw 12. The scraper 13 is threadedly connected to the screw 12. The scraper 13 is made of rubber. The first turntable 14 is fixedly connected to the screw 12. When the first turntable 14 is rotated, the first turntable 14 will rotate with the screw 12, so that the scraper 13 moves down and contacts the ground. The operator pushes the device to move through the handle 5 and drives the paint sprayer 7. The paint sprayer 7 will draw lines on the ground as the device moves, thereby performing the marking work. During this process, the scraper 13 will move along the ground, and the scraper 13 will remove sand and impurities in front of the device's moving route.

[0023] like Figure 1-Figure 2 and Figure 4 As shown, it also includes a worm wheel 15, a second connecting shaft 16, a worm 17, a second turntable 18 and a transmission assembly 19. The worm wheel 15 is fixedly connected to the outer wall of the first connecting shaft 3, and the second connecting shaft 16 is rotatably connected to the vehicle body 1. The front part of the second connecting shaft 16 is welded with a worm 17, and the worm 17 is engaged with the worm wheel 15. The second turntable 18 is rotatably connected to the handle 5, and a transmission assembly 19 is arranged between the second turntable 18 and the second connecting shaft 16. The transmission assembly 19 is composed of a pulley and a belt. After rotating the second turntable 18, the second turntable 18 will rotate with the transmission assembly 19, and the transmission assembly 19 will rotate with the second connecting shaft 16. At this time, the worm 17 on the second connecting shaft 16 will rotate with the worm wheel 15, and the worm wheel 15 will rotate with the first connecting shaft 3 and the bogie 4, and the bogie 4 will rotate with the front moving wheel 2.

[0024] like Figure 1 and Figure 4 As shown, it also includes a pointer 20 and a scale ring 21. The pointer 20 is welded to the upper end of the first connecting shaft 3, and the scale ring 21 is provided on the vehicle body 1. The pointer 20 is located on the inner side of the scale ring 21. When the moving wheel 2 rotates, the pointer 20 will rotate together. The angle that the front moving wheel 2 has rotated is judged according to the value of the scale ring 21 pointed by the pointer 20, thereby ensuring the accuracy of adjusting the angle of the moving wheel 2 and effectively improving the accuracy of the marking of the device.

[0025] When the device is to be used, first fill the paint sprayer 7 with the marking paint liquid, then move the device to the place of use by the moving wheel 2, and then decide the direction of rotating the second turntable 18 according to the bending direction of the marking line. After rotating the second turntable 18, the second turntable 18 will rotate with the transmission assembly 19, and the transmission assembly 19 will rotate with the second connecting shaft 16. At this time, the worm 17 on the second connecting shaft 16 will rotate with the worm gear 15, and the worm gear 15 will rotate with the first connecting shaft 3 and the bogie 4, and the bogie 4 will rotate with the front moving wheel 2. When the moving wheel 2 rotates, the pointer 20 will rotate together, and it can be judged that the front moving wheel 2 has rotated according to the value of the scale ring 21 pointed by the pointer 20. The angle of movement of the front moving wheel 2 is adjusted, thereby ensuring the accuracy of the angle adjustment of the moving wheel 2 and effectively improving the accuracy of the marking of the device; when the pointer 20 rotates to the scale ring 21 of the preset value, stop rotating the second turntable 18, which completes the adjustment of the front moving wheel 2. After the adjustment is completed, the worm gear 15 and the worm 17 can achieve self-locking, so that the device can quickly adjust the angle of the front moving wheel 2. The operation is simple and there is no need for the operator to bend down to manually adjust the front moving wheel 2, which effectively reduces the burden on the operator; after completing the angle adjustment of the front moving wheel 2, rotate the first turntable 14, and the first turntable 14 will rotate with the screw 12, so that the scraper 13 moves down and contacts the ground, and the operator pushes the device to move by the handle 5. , and drive the paint sprayer 7, which will draw lines on the ground as the device moves, thereby performing the marking work. During this process, the scraper 13 will move along the ground, and the scraper 13 will remove the sand and impurities in front of the device's moving route, thereby ensuring that the paint liquid can be closely attached to the ground during subsequent marking, making it difficult for the subsequent paint liquid to separate from the ground, thereby ensuring the marking quality of the device; when the ground on the other side of the device is to be marked, the mounting plate 6 is rotated toward the side close to the handle 5. When the mounting plate 6 rotates, the paint sprayer 7 will rotate together with it, and the mounting plate 6 will slide along the inclined surface on the first guide block 8. At this time, the first guide block 8 will be pressed down, and the connecting spring 10 will be compressed. When the mounting plate 6 is pressed down, the connecting spring 10 will be compressed. After the contact with the first guide block 8 is disconnected, the connecting spring 10 will bring the first guide block 8 back to its original position, and the mounting plate 6 will continue to rotate. The mounting plate 6 will contact the first guide block 8 on the other side and move along the inclined surface of the first guide block 8 on the other side. After the mounting plate 6 is disconnected from the first guide block 8 on the other side, the first guide block 8 on the other side is reset to re-fix the mounting plate 6. At this time, the paint sprayer 7 is located on the other side of the device, thereby completing the position change operation of the paint sprayer 7. This enables the device to change the marking orientation of the device without moving the device itself, and the above steps of replacing the paint sprayer 7 are simple to operate. It only requires rotating the mounting plate 6, which effectively improves the marking efficiency of the device and saves time.After the work is completed, the first rotary disc 14 is rotated to move the scraper 13 upward along the screw 12 and to disconnect the lower surface of the scraper 13 from the ground. This ensures that when the device is in operation, the scraper 13 does not contact the ground, reducing wear on the scraper 13. The device is then closed.
