After the top block leaves the road surface, the torsion spring loses pressure and begins to reset. After the torsion spring resets, it drives the material storage door to reset. At this time, excess material in the material storage box is stored until next use, saving resources. The secondary utilization makes paving faster and improves the efficiency of resource utilization.

[0008] Cold mix semi-flexible pavement construction method, including: Step 1: Drive the device to the place where it is needed. The long support plate and the short support plate prevent the mixing tank from falling during transportation. Then, deliver the material to the feeding port of the mixing tank on the vehicle plate. When the material enters the mixing tank, start the servo motor. At this time, the servo motor drives the stirring rod to rotate. Then the stirring rod drives the long support rod and the short support rod to rotate. The rotation of the long support rod drives the U-shaped stirring plate to rotate. The U-shaped stirring plate drives the connecting column and the tension torsion spring to rotate. At the same time, the U-shaped stirring plate also drives the push plate and the resisting plate to rotate. Finally, the connecting column drives the arched brush plate to rotate. The rotation of the short support rod drives the stirring support plate to rotate. The rotation of the stirring support plate drives the stirring blade to rotate, so as to fully stir the material. Step 2: When the material mixing is completed, the output power of the servo motor increases and drives the stirring rod to rotate rapidly. The rapid rotation of the stirring rod generates a large centrifugal force. The arched brush plate rotates right around the connecting column under the influence of the centrifugal force. When the arched brush plate rotates to a certain angle, it contacts the push plate. The push plate pushes the L-shaped scraper along the scraper groove of the arched brush plate. After the arched brush plate is parallel to the U-shaped stirring plate, the push plate stops pushing. At this time, the L-shaped scraper and the arched brush plate are close to the inner wall of the stirring tank and clean up the residual material attached to the inner wall of the stirring tank. When the L-shaped scraper encounters a residual material that is difficult to clean, the L-shaped scraper is blocked and approaches the push plate, so that the push plate provides support for the L-shaped scraper to clean up the attached residual material. When the stirring rod rotates slowly, the L-shaped scraper and the arched brush plate are reset. After the L-shaped scraper is reset, it is close to the push plate. The push plate prevents the L-shaped scraper from slipping from the arched brush plate during stirring, thereby improving the cleaning efficiency. Automatic cleaning saves time and prevents excessive residual material from being attached to the inner wall of the stirring tank, causing waste. Step 3: The stirring rod rotates to drive the wheel to rotate. When the wheel rotates, it contacts the T-shaped control rod. Due to the special structure of the outer side of the wheel, the T-shaped control rod is pushed forward. The T-shaped control rod is pushed forward along the support block. The movement of the T-shaped control rod drives the short slot column to move. The short slot column moves upward along the short inclined slot. The short inclined slot is pushed upward by the force of the short slot column. Then the short inclined slot is pushed upward to drive the lifting rod upward, and the connecting rod finally drives the discharge door upward. When the discharge door is pushed upward, the material flows out from the discharge port and flows along the discharge port to the control plate. The guide plate evenly transports the material to the road surface to be paved. Step 4: When the stirring rod stops rotating, the wheel stops rotating, and the T-shaped control rod loses the force of the wheel and gradually resets. The reset of the T-shaped control rod drives the short slot column to move downward, and the short slot column moves downward to drive the short inclined slot to move downward. The movement of the short inclined slot drives the connecting rod and the lifting rod to move downward, and the lifting rod moves downward to drive the discharge door to move downward. When the discharge door moves downward to a certain extent, pressure is applied to the deformable material at the bottom. The deformable material is pressed to further seal the internal space to prevent the remaining material in the mixing tank from flowing out at will and causing environmental pollution. The automatic opening and closing of the discharge door provides a certain degree of convenience. Step 5: When the lifting rod moves upward, it drives the long column to move, and the long column moves along the curved slot rod. The curved slot rod moves upward due to the force of the long column, and at the same time, the curved slot rod rotates around the hinged column. The upward movement of the curved slot rod drives the short column to move, and the short column moves downward along the small short slot. The small short slot moves downward due to the force of the short column, and then the small short slot drives the paving board to move downward, and the paving board rotates downward around the button plate. When the paving board contacts the road surface, the roller also contacts the road surface, and the paving board flattens the materials spilled on the ground; Step six: When the collecting plate rotates, the excess material on the paved road surface is cleaned up, and the material cleaned up by the collecting plate is sent into the interior of the storage box from the feeding trough opened on the storage box. After the top block contacts the road surface, it is subjected to the pressure from the road surface and squeezes the torsion spring to rotate upward. The upward rotation of the torsion spring drives the storage door to rotate upward. When the storage door rotates upward, the material stored in the storage box begins to fall on the road surface, and the fallen material is flattened by the paving plate again. The roller moves up and leaves the road surface and stops rotating. After the roller stops rotating, the long connecting column and the roller plate lose the force of the roller and also stop rotating. After the long connecting column and the roller plate stop rotating, the roller and the collecting plate lose the force and also stop rotating. After the top block leaves the road surface, the torsion spring loses pressure and begins to reset. After the torsion spring resets, it drives the storage door to reset. At this time, the excess material in the storage box is stored until the next use, saving resources. The secondary utilization makes paving faster and improves the efficiency of resource utilization.

[0018] Working principle: Drive the device to the place where it is needed, and use the long support plate 5 and the short support plate 6 to prevent the mixing tank 201 from falling during transportation. Then, transport the material to the feed port 202 of the mixing tank 201 on the vehicle plate 1. When the material enters the mixing tank 201, start the servo motor 203. At this time, the servo motor 203 drives the stirring rod 204 to rotate, and then the stirring rod 204 drives the long support rod 205 and the short support rod 213 to rotate. The rotation of the long support rod 205 drives the U-shaped stirring plate 206 to rotate, and the U-shaped stirring plate 206 then rotates. The connecting column 207 and the tension torsion spring 208 are driven to rotate, and the U-shaped stirring plate 206 also drives the push plate 211 and the abutment plate 212 to rotate. Finally, the connecting column 207 drives the arched brush plate 209 to rotate, and the short support rod 213 rotates to drive the stirring support plate 214 to rotate, and the stirring support plate 214 rotates to drive the stirring blade 215 to rotate, so as to fully stir the material. When the material stirring is completed, the output power of the servo motor 203 increases and drives the stirring rod 204 to rotate rapidly. The rapid rotation of the stirring rod 204 generates a large centrifugal force. The arched brush plate 209 is affected by the centrifugal force and rotates to the right around the connecting column 207. When the arched brush plate 209 rotates to a certain angle, it contacts the push plate 211. The push plate 211 pushes the L-shaped scraper 210 along the scraper groove of the arched brush plate 209. After the arched brush plate 209 is parallel to the U-shaped stirring plate 206, the push plate 211 stops pushing. At this time, the L-shaped scraper 210 and the arched brush plate 209 are close to the inner wall of the stirring tank 201 and clean up the residual material attached to the inner wall of the stirring tank 201. The L-shaped scraper 210 encounters a hard-to-clean When the L-shaped scraper 210 is blocked by residual materials, it approaches the push plate 211 after being blocked, so that the push plate 211 provides support for the L-shaped scraper 210 to clean the residual materials attached. When the stirring rod 204 rotates slowly, the L-shaped scraper 210 and the arched brush plate 209 are reset. After the L-shaped scraper 210 is reset, it is tightly attached to the abutment plate 212. The abutment plate 212 prevents the L-shaped scraper 210 from sliding off the arched brush plate 209 during stirring, thereby improving the cleaning efficiency, saving time in automatic cleaning, and preventing excessive residual materials from being attached to the inner wall of the stirring tank 201, causing waste. The stirring rod 204 rotates to drive the rotating wheel 311 to rotate. When the rotating wheel 311 rotates, it contacts the T-shaped control rod 306. Due to the special structure of the outer side of the rotating wheel 311, the T-shaped control rod 306 is pushed forward. The T-shaped control rod 306 is pushed forward along the support block 307. The movement of the T-shaped control rod 306 drives the short slot column 305 to move. The short slot column 305 moves upward along the short inclined slot 304. The short inclined slot 304 is pushed upward by the force of the short slot column 305. Then the short inclined slot 304 is pushed upward to drive the lifting rod 303 to push upward, and the connecting rod 308 finally drives the lifting rod 303 to push the discharge door 302 upward. When the discharge door 302 is pushed upward, the material flows out from the discharge port 301 and flows along the discharge port 301 to the control plate 309, and the guide plate 303 is pushed upward. 10 The materials are uniformly transported to the road surface to be paved. When the stirring rod 204 stops rotating, the wheel 311 stops rotating, and the T-shaped control rod 306 loses the force of the wheel 311 and gradually resets. The T-shaped control rod 306 resets and drives the short slot column 305 to move downward. The short slot column 305 moves downward and drives the short inclined slot 304 to move downward. The movement of the short inclined slot 304 drives the connecting rod 308 and the lifting rod 303 to move downward. The lifting rod 303 moves downward and drives the discharge door 302 to move downward. When the discharge door 302 moves downward to a certain extent, pressure is applied to the deformable material at the bottom. The deformable material is pressed to further seal the internal space to prevent the remaining material in the stirring tank 201 from flowing out at will and causing environmental pollution. The automatic opening and closing of the discharge door 302 provides a certain degree of convenience. When the lifting rod 303 moves upward, it drives the long column 401 to move, and the long column 401 moves along the curved slot rod 402. The curved slot rod 402 moves upward due to the force of the long column 401, and at the same time, the curved slot rod 402 rotates around the hinge column 416. The upward movement of the curved slot rod 402 drives the short column 403 to move, and the short column 403 moves downward along the small short slot 404. The small short slot 404 moves downward due to the force of the short column 403, and then the small short slot 404 drives the paving board 405 to move downward, and the paving board 405 rotates downward around the button plate 406. The downward rotation of the paving board 405 drives the storage box 407 to move downward, and the storage box 407 moves downward and drives the roller 408 to move downward. The downward movement of the roller 408 drives the roller 409 to move downward, and the downward movement of the roller 409 drives the collecting plate 410 to move downward , then roller 409 drives roller 411 downward, roller 411 drives long connecting column 412 downward, long connecting column 412 moves downward and drives roller 413 downward, storage box 407 moves downward and drives storage door 415 downward, storage door 415 moves downward and drives top block 414 downward, paving board 405 contacts the road surface while roller 413 also contacts the road surface, after paving board 405 flattens the materials scattered on the ground, roller 413 rotates along the road surface and drives long connecting column 412 to rotate, and drum 408 remains stationary, long connecting column 412 rotates and drives roller 411 to rotate, roller 411 rotates and drives roller 409 to rotate, and then roller 409 rotates and drives collecting plate 410 to rotate, and collecting plate 410 rotates to flatten the road surface The excess material on the top is cleaned up, and the material cleaned up by the collecting plate 410 is sent into the interior of the storage box 407 from the feeding trough opened on the storage box 407. After the top block 414 contacts the road surface, it is pressed by the pressure from the road surface and squeezes the torsion spring to rotate upward. The upward rotation of the torsion spring drives the storage door 415 to rotate upward. When the storage door 415 rotates upward, the material stored in the storage box 407 begins to fall onto the road surface, and the fallen material is paved again by the paving board 405. When the lifting rod 303 moves downward, the long column 401 moves downward, and the long column 401 moves downward to drive the curved inclined groove rod 402 to move downward. The curved inclined groove rod 402 moves downward to drive the short column 403 to move, and the short column 403 moves upward along the small short groove 404. The upward movement of the small short groove 404 drives the paving board 405 to move upward. The paving board 405 moves up and drives the storage box 407 to move up. The storage box 407 moves up and drives the roller 408 to move up. Then the roller 408 moves up and drives the roller 413 to move up. After the roller 413 moves up and leaves the road surface, it stops rotating. After the roller 413 stops rotating, the long connecting column 412 and the roller 411 lose the force of the roller 413 and also stop rotating. After the long connecting column 412 and the roller 411 stop rotating, the roller 409 and the collecting plate 410 also stop rotating after losing the force. After the top block 414 leaves the road surface, the torsion spring loses pressure and begins to reset. After the torsion spring resets, it drives the storage door 415 to reset. At this time, the excess material in the storage box 407 is stored until the next use, saving resources. The secondary utilization makes paving faster and improves the efficiency of resource utilization.

[0019] Cold mix semi-flexible pavement construction method, including: Step 1: Drive the device to the place where it is needed, and use the long support plate 5 and the short support plate 6 to prevent the mixing tank 201 from falling during transportation. Then, transport the material to the feed port 202 of the mixing tank 201 on the vehicle plate 1. When the material enters the mixing tank 201, start the servo motor 203. At this time, the servo motor 203 drives the stirring rod 204 to rotate, and then the stirring rod 204 drives the long support rod 205 and the short support rod 213 to rotate. The long support rod 205 rotates to drive the U-shaped stirring plate 206 to rotate, and the U-shaped stirring plate 206 then drives the connecting column 207 and the tension torsion spring 208 to rotate. At the same time, the U-shaped stirring plate 206 also drives the push plate 211 and the abutment plate 212 to rotate. Finally, the connecting column 207 drives the arched brush plate 209 to rotate, and the short support rod 213 rotates to drive the stirring support plate 214 to rotate. The stirring support plate 214 rotates to drive the stirring blade 215 to rotate, so as to fully stir the material. Step 2: When the material mixing is completed, the output power of the servo motor 203 increases and drives the stirring rod 204 to rotate rapidly. The rapid rotation of the stirring rod 204 generates a large centrifugal force. The arched brush plate 209 rotates to the right around the connecting column 207 under the influence of the centrifugal force. When the arched brush plate 209 rotates to a certain angle, it contacts the push plate 211. The push plate 211 pushes the L-shaped scraper 210 along the scraper groove of the arched brush plate 209. After the arched brush plate 209 is parallel to the U-shaped stirring plate 206, the push plate 211 stops pushing. At this time, the L-shaped scraper 210 and the arched brush plate 209 are close to the mixing tank 2 01 and clean up the residual materials attached to the inner wall of the mixing tank 201. When the L-shaped scraper 210 encounters the obstruction of the residual materials that are difficult to clean up, the push plate 211 will lend force to the L-shaped scraper 210 to clean it up. When the stirring rod 204 slows down, the L-shaped scraper 210 and the arched brush plate 209 are reset. After the L-shaped scraper 210 is reset, it is tightly attached to the abutment plate 212. The abutment plate 212 prevents the L-shaped scraper 210 from sliding off the arched brush plate 209 during stirring, thereby improving the cleaning efficiency, saving time through automatic cleaning, and preventing excessive residual materials from being attached to the inner wall of the mixing tank 201, causing waste. Step 3: The stirring rod 204 rotates to drive the rotating wheel 311 to rotate. When the rotating wheel 311 rotates, it contacts the T-shaped control rod 306. Due to the special structure of the outer side of the rotating wheel 311, the T-shaped control rod 306 is pushed forward. The T-shaped control rod 306 is pushed forward along the support block 307. The movement of the T-shaped control rod 306 drives the short slot column 305 to move. The short slot column 305 moves upward along the short inclined slot 304. The short inclined slot 304 is pushed upward by the force of the short slot column 305. Then the short inclined slot 304 is pushed upward to drive the lifting rod 303 to push upward, and the connecting rod 308 finally drives the lifting rod 303 to push the discharge door 302 upward. When the discharge door 302 is pushed upward, the material flows out from the discharge port 301 and flows along the discharge port 301 to the material control plate 309. The guide plate 310 evenly transports the material to the road surface to be paved. Step 4: When the stirring rod 204 stops rotating, the rotating wheel 311 stops rotating, and the T-shaped control rod 306 loses the force of the rotating wheel 311 and gradually resets. The reset of the T-shaped control rod 306 drives the short slot column 305 to move downward, and the short slot column 305 moves downward to drive the short inclined slot 304 to move downward. The movement of the short inclined slot 304 drives the connecting rod 308 and the lifting rod 303 to move downward, and the lifting rod 303 moves downward to drive the discharge door 302 to move downward. When the discharge door 302 moves downward to a certain extent, pressure is applied to the deformable material at the bottom. The deformable material is compressed to further seal the internal space to prevent the remaining material in the stirring tank 201 from flowing out at will and causing environmental pollution. The automatic opening and closing of the discharge door 302 provides a certain degree of convenience. Step 5: When the lifting rod 303 moves upward, it drives the long column 401 to move, and the long column 401 moves along the curved slot rod 402. The curved slot rod 402 moves upward due to the force of the long column 401, and at the same time, the curved slot rod 402 rotates around the hinge column 416. The upward movement of the curved slot rod 402 drives the short column 403 to move, and the short column 403 moves downward along the small short slot 404. The small short slot 404 moves downward due to the force of the short column 403, and then the small short slot 404 drives the paving board 405 to move downward, and the paving board 405 rotates downward around the button plate 406. When the paving board 405 contacts the road surface, the roller 413 also contacts the road surface, and the paving board 405 flattens the materials spilled on the ground; Step 6: When the collecting plate 410 rotates, the excess material on the paved road surface is cleaned up, and the material cleaned up by the collecting plate 410 is sent into the interior of the storage box 407 from the feeding trough opened on the storage box 407. After the top block 414 contacts the road surface, it is pressed by the pressure from the road surface and squeezes the torsion spring to rotate upward. The upward rotation of the torsion spring drives the storage door 415 to rotate upward. When the storage door 415 rotates upward, the material stored in the storage box 407 begins to fall onto the road surface, and the fallen material is paved again by the paving plate 405 and moves away from the roller 413. After the road surface is opened, it stops rotating. After the roller 413 stops rotating, the long connecting column 412 and the roller 411 also stop rotating after losing the force of the roller 413. After the long connecting column 412 and the roller 411 stop rotating, the roller 409 and the collecting plate 410 also stop rotating after losing the force. After the top block 414 leaves the road surface, the torsion spring loses pressure and starts to reset. After the torsion spring resets, it drives the storage door 415 to reset. At this time, the excess material in the storage box 407 is stored until the next use, saving resources. The secondary utilization makes paving faster and improves the efficiency of resource use.

The long support plate (5) and the short support plate (6) prevent the mixing tank (201) from falling during transportation. Then, the material is transported to the feed port (202) of the mixing tank (201) on the vehicle plate (1). When the material enters the mixing tank (201), the servo motor (203) is started. At this time, the servo motor (203) drives the mixing rod (204) to rotate. Then, the mixing rod (204) drives the long support rod (205) and the short support rod (213) to rotate. The long support rod (205) The U-shaped stirring plate (206) is driven to rotate by the rotation of the connecting column (207) and the tension torsion spring (208). At the same time, the U-shaped stirring plate (206) also drives the push plate (211) and the stop plate (212) to rotate. Finally, the connecting column (207) drives the arched brush plate (209) to rotate. The short support rod (213) drives the stirring support plate (214) to rotate. The stirring support plate (214) drives the stirring blade (215) to rotate, thereby fully stirring the material. Step 2: When the material is stirred, the output power of the servo motor (203) increases and drives the stirring rod (204) to rotate rapidly. The stirring rod (204) rotates rapidly to generate a large centrifugal force. The arched brush plate (209) rotates rightward around the connecting column (207) under the influence of the centrifugal force. When the arched brush plate (209) rotates to a certain angle, it contacts the push plate (211). The push plate (211) pushes the L-shaped scraper (210) along the scraper groove of the arched brush plate (209). After the arched brush plate (209) and the U-shaped stirring plate (206) are parallel, the push plate (211) stops pushing. At this time, the L-shaped scraper (210) and the arched brush plate (209) are close to the stirring tank. The inner wall of the mixing tank (201) is cleaned and the residual material attached to the inner wall of the mixing tank (201) is cleaned. When the L-shaped scraper (210) encounters residual material that is difficult to clean, the push plate (211) will lend force to the L-shaped scraper (210) to clean it. When the stirring rod (204) rotates slowly, the L-shaped scraper (210) and the arched brush plate (209) are reset. After the L-shaped scraper (210) is reset, it is tightly attached to the abutment plate (212). The abutment plate (212) prevents the L-shaped scraper (210) from sliding off the arched brush plate (209) during stirring, thereby improving the cleaning efficiency, saving time through automatic cleaning, and preventing excessive residual material from being attached to the inner wall of the mixing tank (201) and causing waste; Step 3: The stirring rod (204) rotates to drive the rotating wheel (311) to rotate. When the rotating wheel (311) rotates, it contacts the T-shaped control rod (306). Due to the special structure of the outer side surface of the rotating wheel (311), the T-shaped control rod (306) is pushed forward. The T-shaped control rod (306) is pushed forward along the support block (307). The movement of the T-shaped control rod (306) drives the short slot column (305) to move. The short slot column (305) moves upward along the short inclined slot (304). The short inclined slot (304) The material is pushed upward by the force of the short slot column (305), and then the short inclined slot (304) is pushed upward to drive the lifting rod (303) to be pushed upward, and the connecting rod (308) finally drives the lifting rod (303) to drive the discharge door (302) to be pushed upward. While the discharge door (302) is pushed upward, the material flows out from the discharge port (301) and flows along the discharge port (301) to the material control plate (309), and the guide plate (310) evenly transports the material to the road surface to be paved; Step 4: When the stirring rod (204) stops rotating, the rotating wheel (311) stops rotating, and the T-shaped control rod (306) gradually resets after losing the force of the rotating wheel (311). The T-shaped control rod (306) resets and drives the short slot column (305) to move downward. The short slot column (305) moves downward and drives the short inclined slot (304) to move downward. The movement of the short inclined slot (304) drives the connecting rod (308) and the lifting rod (303) to move downward. The lifting rod (303) moves downward and drives the discharge door (302) to move downward. When the discharge door (302) moves downward to a certain extent, pressure is applied to the deformable material at the bottom. The deformable material is pressed to further seal the internal space, thereby preventing the remaining material in the stirring tank (201) from flowing out at will and causing environmental pollution. The automatic opening and closing of the discharge door (302) provides a certain degree of convenience. Step 5: When the lifting rod (303) moves upward, it drives the long column (401) to move, and the long column (401) moves along the curved slot rod (402). The curved slot rod (402) moves upward due to the force of the long column (401). At the same time, the curved slot rod (402) rotates around the hinge column (416). The upward movement of the curved slot rod (402) drives the short column (403) to move, and the short column (403) moves downward along the small short slot (404). The small short slot (404) moves downward due to the force of the short column (403), and then the small short slot (404) drives the paving plate (405) to move downward, and the paving plate (405) rotates downward around the button plate (406). When the paving plate (405) contacts the road surface, the roller (413) also contacts the road surface, and the paving plate (405) flattens the materials spilled on the ground; Step 6: When the collecting plate (410) rotates, the excess material on the paved road surface is cleaned up. The material cleaned up by the collecting plate (410) is fed into the interior of the storage box (407) from the feeding slot provided on the storage box (407). After the top block (414) contacts the road surface, it is pressed by the pressure from the road surface and squeezes the torsion spring to rotate upward. The upward rotation of the torsion spring drives the storage door (415) to rotate upward. When the storage door (415) rotates upward, the material stored in the storage box (407) begins to fall onto the road surface. The fallen material is again paved by the paving plate (405), and the roller (413) moves upward to leave. After the top block (414) leaves the road surface, the torsion spring loses pressure and starts to reset. After the torsion spring resets, the storage door (415) is driven to reset. At this time, the excess material in the storage box (407) is stored until the next use, thereby saving resources. The secondary use makes the paving faster and improves the use efficiency of resources.
