[0032] In the technical scheme, the concrete enters the mixing box, is stirred by the first stirring helical blade, enters the discharging barrel, and then falls into the discharging bin, passes through the guide plate, falls to the road surface through the discharging hole, the inner wall of the discharging bin is provided with the scraping plate extending out of the lower end of the discharging bin, the concrete on the road surface can be further scraped, the labor cost is reduced, and the construction efficiency is improved. It should be noted that the roadbed construction pouring device needs to be installed on the moving device for pouring operation. In addition, the first stirring helical blade 9 is arranged on the rotating shaft 8, and the rotating shaft 8 rotates by relying on the motor 25.
[0033] Further, the scraping plate 16 is provided with two scraping plates, the lower end of the scraping plate 16 is formed with an inclined scraping surface, a plurality of support columns 24 are fixedly arranged between the two scraping plates 16, and the upper ends of the two scraping plates 16 are fixedly connected through a plurality of connecting blocks 30. In the technical scheme, the scraping plate 16 is provided with two scraping plates, and the inclined scraping surface formed at the lower end of the scraping plate 16 can further ensure the scraping effect of the concrete. The arrangement of the plurality of support columns and the plurality of connecting blocks improves the structural strength of the two scraping plates and prolongs the service life of the scraping plate.
[0034] Further, the side wall of the discharging bin 11 is fixedly connected with a support plate 20, a plurality of threaded columns 21 are fixedly arranged on the support plate 20 and correspond to the connecting blocks 30, the threaded columns 21 are threadedly connected with bolts 22, the lower ends of the bolts 22 extend into the two scraping plates 16 and are threadedly connected with the connecting blocks 30, and the upper ends of the bolts 22 are provided with nuts 23. In the technical scheme, the height of the scraping plate relative to the road surface can be adjusted through the threaded cooperation of the bolts and the connecting blocks, and the height can be adjusted according to the falling height of the concrete and the required pouring height.

In addition, the limiting plate 31 can limit the lower end of the bolt, preventing the bolt from being detached from the connecting block.
[0035] Further, the side wall of the discharging bin 11 is provided with adjusting holes 19 corresponding to the plurality of bolts 22. In the technical scheme, the adjusting holes are arranged to facilitate the staff to act on the nuts through the adjusting holes to adjust the height of the scraping plate.
[0036] Further, the plurality of discharging holes 13 gradually increase in diameter from the middle to the two sides. In the technical scheme, the discharging hole in the middle is smaller but the concrete falls faster, so that the plurality of discharging holes 13 gradually increase in diameter from the middle to the two sides, so that the concrete falls more uniformly, and the flatness is improved after the concrete is scraped.
[0037] Further, the material guide plate 12 is configured as a downwardly recessed arc shape. In this technical solution, the material guide plate 12 is configured as a downwardly recessed arc shape, which can enable the concrete falling on the material guide plate to be guided out of the arc-shaped discharge hole, improve the pouring area, and make the pouring more uniform. In addition, the arc-shaped material guide plate can facilitate the installation of the second stirring spiral blade close thereto, thereby providing a certain installation space.
[0038] Further, the discharge bin 11 is rotatably provided with a roller shaft 14 above the material guide plate 12, two second stirring spiral blades 15 are fixedly sleeved on the two sides of the roller shaft 14, and the rotation directions of the two second stirring spiral blades 15 are opposite.

In this technical solution, the partition plate can separate the concrete falling from the discharge cylinder to the two sides, and the concrete is uniformly thrown out by the second stirring spiral blades on the two sides, thereby preventing the falling amount of the concrete from being too large and concentrated in the middle of the material guide plate, and affecting the uniformity of the concrete pouring.
[0040] Further, a plurality of bosses 5 are fixedly arranged on the two side walls of the stirring box 1, a lead screw 7 is fixedly arranged on the upper ends of the two sides of the discharge bin 11, the lead screw 7 passes through the bosses 5, a plurality of adjusting nuts 6 are threadedly connected to the lead screw 7, the adjusting nuts 6 are arranged on the two sides of the bosses 5, and the discharge cylinder 10 is a telescopic cylinder.

The height of the material scraping plate can be further adjusted, and the height of the concrete after falling can be adjusted, thereby improving the construction efficiency.
[0041] Further, a feeding pipe 3 is fixedly arranged on the upper end of the material inlet 2, and a flange plate 4 is fixedly arranged on the upper end of the feeding pipe 3. In this technical solution, the flange plate can be effectively fixed with an external pipeline conveying concrete, thereby improving the structural strength.
[0042] In the specific embodiment, the existing roadbed pouring device still needs manual concrete scraping after discharging the concrete, which is time-consuming and labor-intensive and affects the construction progress. The above-mentioned solution sets a material scraping plate extending out of the lower end of the discharge bin on the inner wall of the discharge bin,
[0043] After entering the mixing box, concrete is stirred by the first stirring spiral before entering the discharge barrel and falling into the discharge hopper. It then passes through the guide plate and the discharge hole onto the road surface. The scraper plate further smoothes the concrete on the road surface, reducing labor costs and improving construction efficiency. The height of the scraper plate is adjustable, allowing adjustments to be made to the concrete's smoothing height and the required pouring height. Furthermore, the guide plate is curved, the discharge hole gradually widens along its sides, and a second stirring spiral is added, ensuring a more even distribution of falling concrete. Furthermore, by adjusting the screw nut and screw rod, configuring the discharge barrel as a telescopic barrel, and securing the mixing box to a mobile device, the height of the discharge hopper can be adjusted by acting on the adjusting nut. This not only further adjusts the height of the scraper plate, but also the height of the concrete after it has fallen. This can be adjusted based on the pouring height of the road surface, improving construction efficiency.
