[0002] With the progress of highway reconstruction and expansion, a large amount of inorganic recycled materials from the base layer are generated during the road widening process. The inorganic recycled materials after milling the base layer are simply referred to as water-stable milled materials. Due to their difficult compressibility and degradability, it will cause greater waste of land resources and building materials. At present, great attention is paid to ecological environmental protection. Therefore, research on the classification treatment and resource reuse of construction waste is carried out to reduce the environmental protection pressure. For the recycling of construction waste, the current highway development has entered the stage of equal emphasis on construction and maintenance.

[0003] In previous engineering practices, they were often discarded, which not only wasted materials but also polluted the environment. In view of this problem, it is necessary to mix the water-stable milled materials milled from the road surface with new materials, and prepare qualified concrete through experimental testing for the construction of small precast components to realize the recycling of old water-stable road surface materials.

The other end of the transmission shaft is located on one side of the double-shaft motor and a first bevel gear is fixedly sleeved on the outer wall.

[0009] Specifically, in this technical solution, a support block is sleeved on the transmission shaft. The bottom end of the support block is fixedly connected to the upper surface of the top plate by screws. Two telescopic rods are symmetrically provided on both sides of the sleeve. The telescopic ends of the two telescopic rods are fixedly connected to the top end of the partition board by screws. The top ends of the two telescopic rods are fixedly connected to the lower surface of the top plate by screws. One side of the partition board is in contact with the end face of the pouring pipe.

A second bevel gear is fixedly sleeved on the outer wall of one of the shaft rods, and the second bevel gear is meshed with a first bevel gear arranged in the blocking assembly.

[0011] Specifically, in this technical solution, the scraping assembly includes two winding rollers. The end faces of both shaft rods are fixedly connected to the ends of the winding rollers through flanges. The other ends of both winding rollers are rotatably connected to the inner side wall of the protective shell. And ropes are wound around both winding rollers. Both ropes penetrate through the top plate in an L shape and are connected to a U-shaped scraper. The outer walls of both U-shaped scrapers are in contact with the inner pipe wall of the pouring pipe. One side of both U-shaped scrapers is in contact with the end face of a partition board arranged in the blocking assembly.

[0012] Specifically, in this technical solution, a horizontal guide rod is provided at the bent part of both ropes.

The first bevel gear transmits the rotational force to the worm through the transmission shaft, and the worm drives the worm gear and the lead screw to rotate. The partition board moves downward through the sleeve under the restriction of the telescopic rod, and the sleeve pushes the partition board to move; At this time, the rotation of the take-up roller relaxes the wound drawstring, so that the partition plate drives the U-shaped scraper to move simultaneously when moving downward. The U-shaped scraper tightens the relaxed drawstring until the U-shaped scraper contacts the inner wall of the pouring pipe. The pouring pipe is closed by the partition plate to prevent the residual concrete from falling onto the production line through the replacement gap when replacing the mold plate, reducing the pollution of the mechanical surface and the workload of subsequent cleaning. At the same time, when it is necessary to wash the concrete attached to the inner wall of the hopper, the second electric telescopic cylinder can be used to push the U-shaped scraper to move along the inner wall of the pouring pipe to remove the firmly attached concrete. Then the processing mechanism resets, facilitating the washing of the scraped concrete away by the flowing water when washing the hopper, ensuring the cleanliness of the pouring pipe, preventing blockage caused by concrete solidification, and ensuring smoothness.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0019] The following will describe the embodiments according to the overall structure of the present invention. Embodiment

[0020] Please refer to Figures 1 to 2 As shown, the preparation process of the anti-drainage concrete precast member using the water-stable milling material includes the following steps: Step 1: Milling the old road surface. Use a water-stable milling machine to cut and mill the old water-stable road surface, remove the aged and damaged water-stable layer, collect the milling material, discard the large old materials with a particle size greater than 5 cm, and transport the collected milling material to the regeneration treatment bin by a transport vehicle to ensure the purity and reuse value of the milling material. Step 2: Regeneration treatment. Crush the transported milling material so that the particle size of the milling material is controlled within 4 - 5 mm, and then the crushed water-stable milling material is screened through a sieve mesh. The screened materials are transported to the stacking area by a conveyor belt to ensure the uniformity and stability of the materials. Step 3: Batching and mixing. Thoroughly mix the screened water-stable milling material with new materials in a mixer truck to form concrete that meets the requirements, and transport the prepared concrete to the intelligent automated production line for small precast members. The new materials include cement, water, machine-made sand, and water reducer, and are mixed with the water-stable milling material according to the mix ratio after laboratory testing. Step 4: Preparation and curing of the anti-drainage concrete precast member. The mixer truck pours the mixed concrete into the feeding bin of the batching system. The feeding bin moves up and laterally to above the batching hopper 1, and the concrete is poured into the batching hopper 1. The batching hopper 1 pours the concrete into the mold of the mold plate through the pouring pipe 101 and performs automatic vibration to form a preliminary shaping, and then it is transported to the stacking system where the mold plates are stacked together in sequence, and then transported to the curing kiln for curing to improve the flatness, density, and stability of the small precast members. Finally, the cured anti-drainage concrete precast members are palletized through an automatic palletizing system to complete the preparation.

[0021] Using this construction method, both the quality of the components and the process efficiency have been greatly improved compared with the traditional method. In the case of continuously increasing material costs, it reduces the demand for new materials, reduces carbon emissions, realizes conservation and green development, and can significantly reduce the overall project cost and improve the economic benefits of the project. It has received unanimous praise from the construction unit and the supervision unit, and realizes the recycling of water-stable road surface materials.

[0022] Please refer toFigures 2 to 5 As shown, there are two pouring pipes 101 which are symmetrically installed at the discharge opening of the hopper 1. Above the two pouring pipes 101, there is a top plate 102. One side outer wall of the top plate 102 is fixed to the bottom of the outer wall of the hopper 1 by three evenly arranged connecting rods 1021 with screws. At the top end of the top plate 102, two protective shells 1022 are installed with screws. Below the two pouring pipes 101, there are support plates 202 lapped. On one side of each of the two pouring pipes 101, there is a movable seat 201. The bottom ends of the two movable seats 201 are fixedly connected to the upper surface of the support plate 202 by screws. On both side walls at the bottom of the hopper 1, mounting blocks 103 are fixed by screws. A first electric telescopic cylinder 2 passes through each of the two mounting blocks 103. The telescopic ends of the two first electric telescopic cylinders 2 are fixedly connected to the movable blocks of the movable seats 201 with screws; In each of the two protective shells 1022, there is a treatment mechanism 3. The treatment mechanism 3 is composed of a blocking component 4, a double-shaft motor 5 and a scraping component 6. The double-shaft motor 5 is used to control the lifting of the blocking component 4 and the scraping component 6. The blocking component 4 is used to close the end face of the pouring pipe 101. The scraping component 6 is used to scrape off the concrete attached to the inner wall of the pouring pipe 101. The double-shaft motor 5 is fixed to the top plate 102 with screws. On both output ends of the double-shaft motor 5, a shaft rod 501 is installed by flange. On the outer wall of one shaft rod 501, a second bevel gear 502 is fixedly sleeved. The second bevel gear 502 is meshed and connected with the first bevel gear 4061 arranged in the blocking component 4. All the electrical components in this device are automatically controlled by the controller of the production line.

[0023] When pouring the prepared concrete through the hopper 1, whenever the pouring of the mold on one formwork is completed, the discharge pump of the hopper 1 stops, and the concrete remaining in the pouring pipe 101 may drip under the action of gravity. During the movement of replacing the new formwork, there will be a gap under the hopper 1, which may cause the dripping concrete to fall onto the production line. To avoid this phenomenon, whenever the formwork is replaced and moved, the double-shaft motor 5 is started. The output end of the double-shaft motor 5 drives the shaft rod 501 to rotate, so that the sleeved second bevel gear 502 rotates. The two rotating shaft rods 501 will drive the winding part (the winding roller 601 in the text) of the scraping component 6 to rotate. At the same time, the second bevel gear 502 will drive the meshed first bevel gear 4061 to rotate. Through the first bevel gear 4061, the actuator (the partition board 401 in the text) in the blocking component 4 is controlled to move downwards, thereby closing the end face of the pouring pipe 101, avoiding the remaining concrete from falling onto the production line through the replacement gap, reducing the pollution of the mechanical surface, and reducing the workload of subsequent cleaning; When it is necessary to wash and clean the inner wall of the cloth hopper 1 to remove the attached concrete, at this time, the blocking component 4 and the scraping component 6 will move downward under the control of the double-shaft motor 5 to contact the pouring pipe 101. Then, the actuator of the scraping component 6 (the U-shaped scraper 604 in the text) will move along the inner pipe wall of the pouring pipe 101 under the action of the driving component (the second electric telescopic cylinder 6051 in the text) to remove the more firmly attached concrete. Then, the whole processing mechanism 3 resets. At this time, the sewage flushing the inside of the cloth hopper 1 will flow through the pouring pipe 101 to wash away the scraped concrete together, ensuring the cleanliness of the pouring pipe 101, preventing the concrete from solidifying and causing blockage, and ensuring smoothness.

[0024] The blocking component 4 includes a partition board 401. A fixed sleeve 403 is fixed at the center of the top end of the partition board 401. A lead screw 404 is arranged in the sleeve 403. The top end of the lead screw 404 penetrates through the top plate 102 and is rotatably connected to the inner top wall of the protective shell 1022. A worm gear 4041 is fixedly sleeved on the outer wall of the top of the lead screw 404. A transmission shaft 406 is horizontally arranged on one side of the worm gear 4041. One end of the transmission shaft 406 is rotatably connected to the inner wall of the protective shell 1022. A worm 405 is fixedly sleeved on the outer wall of the transmission shaft 406 at the position of the worm gear 4041. The worm 405 is meshed with the worm gear 4041. The other end of the transmission shaft 406 is located on one side of the double-shaft motor 5 and a first bevel gear 4061 is fixedly sleeved on the outer wall. A support block 4062 is sleeved on the transmission shaft 406. The bottom end of the support block 4062 is fixedly connected to the upper surface of the top plate 102 by screws. Expansion rods 402 are symmetrically arranged on both sides of the sleeve 403. The telescopic ends of the two expansion rods 402 are fixedly connected to the top end of the partition board 401 by screws. The top ends of the two expansion rods 402 are fixedly connected to the lower surface of the top plate 102 by screws. One side of the partition board 401 is in contact with the end face of the pouring pipe 101; The scraping assembly 6 includes two winding rollers 601. The end faces of the two shaft rods 501 are fixedly connected to the ends of the winding rollers 601 through flanges. The other ends of the two winding rollers 601 are rotatably connected to the inner side wall of the protective shell 1022. And ropes 603 are wound around the two winding rollers 601. The two ropes 603 both pass through the top plate 102 in an L shape and are connected to U-shaped scraping plates 604. The outer walls of the two U-shaped scraping plates 604 are in contact with the inner pipe wall of the pouring pipe 101. One side of each of the two U-shaped scraping plates 604 is in contact with the end face of the partition plate 401 provided in the blocking assembly 4. A horizontal guide rod 602 is provided at the bent portion of the two ropes 603. One end of each of the two guide rods 602 is rotatably connected to the inner side wall of the protective shell 1022. A fixing plate 6021 is installed on the upper surface of the top plate 102 through screws at the end face of the guide rod 602. The other ends of the two guide rods 602 are rotatably connected to the plate surface of the fixing plate 6021. An inclined block 605 is installed on the side of the partition plate 401 away from the pouring pipe 101 through screws. Second electric telescopic cylinders 6051 are symmetrically embedded in the inclined block 605. The telescopic ends of the two second electric telescopic cylinders 6051 both pass through the partition plate 401 and are fixedly connected to the U-shaped scraping plate 604 by screws.

[0025] The two shaft rods 501 on the dual-axis motor 5 drive the connected winding rollers 601 to rotate. And the rotation of the second bevel gear 502 drives the meshing first bevel gear 4061 to rotate. The first bevel gear 4061 drives the penetrating transmission shaft 406 to rotate. The transmission shaft 406 drives the worm 405 to rotate. The worm 405 drives the meshing worm gear 4041 to rotate. The worm gear 4041 drives the penetrating lead screw 404 to rotate. The partition plate 401 moves downward along with the lead screw 404 under the restriction of the telescopic rod 402 through the sleeve 403. At the same time, the rotation of the two winding rollers 601 slackens the wound ropes 603. So that when the partition plate 401 moves downward, it drives the U-shaped scraping plate 604 to move simultaneously. The U-shaped scraping plate 604 tightens the slack ropes 603 until the U-shaped scraping plate 604 is in contact with the inner pipe wall of the pouring pipe 101. At this time, the partition plate 401 will be located at the end of the pouring pipe 101 and close it. When flushing the concrete adhering to the inner wall of the hopper 1, through the operation of the treatment mechanism 3, the U-shaped scraping plate 604 is located at the inner pipe wall of the pouring pipe 101, and the partition plate 401 is located at the end of the pouring pipe 101. At this time, the second electric telescopic cylinder 6051 is started, and its telescopic end pushes the U-shaped scraping plate 604 to move along the inner pipe wall of the pouring pipe 101 to remove the firmly adhered concrete. Then the treatment mechanism 3 resets, facilitating the flushing of the scraped concrete by the flowing water when flushing the hopper 1.

[0026] The working principle of the present invention is as follows: Whenever the model plate is replaced and moved, the double-shaft motor 5 is started. The output end of the double-shaft motor 5 drives the shaft rod 501 to rotate, causing the sleeved second bevel gear 502 to rotate. The two shaft rods 501 drive the connected winding rollers 601 to rotate, and the rotation of the second bevel gear 502 drives the meshing first bevel gear 4061 to rotate. The first bevel gear 4061 drives the penetrated transmission shaft 406 to rotate, and the transmission shaft 406 drives the worm 405 to rotate. The worm 405 drives the meshing worm gear 4041 to rotate, and the worm gear 4041 drives the penetrated lead screw 404 to rotate. The baffle plate 401 moves downward following the rotation of the lead screw 404 through the sleeve 403 under the restriction of the telescopic rod 402; At the same time, the rotation of the two winding rollers 601 will slacken the wound draw rope 603, so that when the baffle plate 401 moves downward, it drives the U-shaped scraper 604 to move simultaneously. The U-shaped scraper 604 tightens the slack draw rope 603 until the U-shaped scraper 604 contacts the inner wall of the pouring pipe 101. At this time, the baffle plate 401 will be located at the end of the pouring pipe 101 and close it; When flushing the concrete attached to the inner wall of the hopper 1, through the operation of the processing mechanism 3, the U-shaped scraper 604 is located at the inner wall of the pouring pipe 101, and the baffle plate 401 is located at the end of the pouring pipe 101. At this time, the second electric telescopic cylinder 6051 is started, and its telescopic end pushes the U-shaped scraper 604 to move along the inner wall of the pouring pipe 101 to remove the firmly attached concrete. Then the processing mechanism 3 resets, facilitating the flushing of the scraped concrete by the flowing water when flushing the hopper 1.
