[0027] Reference Figure 2 , 5 , further, the uniform scraping mechanism is composed of a feeding frame 503, an electric telescopic rod A504, an electric telescopic rod B505 and a scraping frame 506;

[0028] A feeding rack 503 is embedded in the middle of the other end of the outer wall of the feeding chamber 5.

The other end of the electric telescopic rod A504 is provided with a scraper rack 506 through a rotating shaft, and the scraper rack 506 is arranged in an arc shape. An electric telescopic rod B505 is provided between the other end of the top of the outer wall of the scraper rack 506 and the outer wall of the feeding rack 503 through a rotating shaft. When a small amount of cement concrete slurry is evenly transported to the other end of the feeding rack 503 through the rotating spiral feeding rod 601, The staff controls the screw rail B4 to drive the feeding chamber 5 to move to the left through the slider, and drives the feeding rack 503 to slide into the casting chamber 201. The staff then controls the screw rail B4 to drive the feeding rack 503 at the other end of the feeding chamber 5 to continuously move left and right inside the casting chamber 201 through the slider, so that the cement concrete slurry is evenly spread on the inner wall of the casting chamber 201. At the same time, the staff turns on the service motor A2 to drive the casting chamber 201 to rotate at a high speed, so that the cement concrete slurry is evenly contacted with the inner wall of the casting chamber 201 by the centrifugal force generated by the high-speed rotating casting chamber 201.

[0030] Reference Figure 1 , 2, 3, 5, further, the inner wall material of the casting chamber 201 is modified PVC. Since the modified PVC material has the characteristics of waterproof and moisture-proof, the inner wall of the casting chamber 201 will not be easily damaged by moisture when it contacts the cement concrete slurry for a long time.

[0031] like Figure 1 , 2 As shown in Figures 3 and 5, in addition to the embodiment in which the inner wall material of the casting chamber 201 is modified PVC, the utility model also has another embodiment in which the inner wall material of the casting chamber 201 is made of polytetrafluoroethylene. Since polytetrafluoroethylene has the characteristics of corrosion resistance, water resistance and moisture resistance, the inner wall of the casting chamber 201 will not be easily damaged by moisture when in contact with cement concrete slurry for a long time. At the same time, the inner wall of the casting chamber 201 made of polytetrafluoroethylene with high lubricity and non-stick properties can be in contact with cement concrete slurry for a long time without causing adhesion between the cement concrete slurry and the inner wall of the casting chamber 201 after drying.

[0032] Working principle: First, when a large number of culverts need to be produced, the staff will introduce the prepared cement concrete slurry from the feed port 501 into the feeding chamber 5, and then turn on the servo motor B6 to drive the spiral feeding rod 601 and the outer wall bevel gear 602 to rotate, so that the teeth of the bevel gear 602 and the other bevel gear 602 are engaged and transmitted, which will drive the rotating rod A507 through the bearing transmission. At this time, the rotating rod A507 drives the rotating rod B7 through the top outer chain through the bearing transmission, and drives the bottom stirring frame 701 of the rotating rod B7 to rotate in the prepared cement concrete slurry through the bearing, so that the cement concrete slurry continuously passes through the convex blocks 703 between the opposite blades 702, is squeezed and dispersed, and the static cement concrete slurry produces a After the fluidity is determined, the cement concrete slurry can be prevented from agglomerating due to being left standing for too long. Then, the staff turns on the servo motor C8 and drives the feeding wheel 801 through the bearing to rotate inside the guide trough 508 through the chain on the outer side of the output shaft. Part of the cement concrete slurry will be filled into the trapezoidal feeding trough 802, and after the feeding trough 802 filled with cement concrete slurry rotates to the bottom, the cement concrete slurry will be evenly discharged from the feeding trough 802 to the bottom of the inner side of the feeding chamber 5. A small amount of cement concrete slurry will be evenly transported to the other end through the rotating spiral feeding rod 601, which can prevent the cement concrete slurry from being discharged too much and causing waste. Finally, the staff controls the screw slide rail B4 to drive the feeding chamber 5 to move to the left through the slider. After driving the feeding rack 503 to slide into the casting chamber 201, the staff controls the screw slide rail B4 to drive the feeding rack 503 at the other end of the feeding chamber 5 to continuously move left and right inside the casting chamber 201 through the slider, so that the cement concrete slurry is evenly spread on the inner wall of the casting chamber 201. At the same time, the staff turns on the service motor A2 to drive the casting chamber 201 to rotate at a high speed, so that the cement concrete slurry is evenly contacted with the inner wall of the casting chamber 201 by the centrifugal force generated by the high-speed rotating casting chamber 201. At the same time, the staff controls the electric telescopic rod A504 and the electric telescopic rod B505 to drive the scraper rack 506 to change its angle through the rotating shaft and extend it or extend it in parallel with the inner wall of the casting chamber 201, so as to contact a large amount of cement concrete on the inner wall of the casting chamber 201. After the slurry surface is smoothed, the cement concrete slurry is scraped flat, and after the cement concrete slurry gradually hardens and the pouring production of one of the culverts is completed, the staff controls the screw slide rail B4 to drive the feeding chamber 5 to move left and right through the slider, and drives the feeding rack 503 to slide out of the pouring chamber 201. The staff controls the screw slide rail A3 to drive the bottom limit plate 302 of the hydraulic rod 301 to move to the inner side of the groove 203 on the surface of the stop cover 202 through the slider. The staff then controls the hydraulic rod 301 to retract the limit plate 302, and drives the limit groove 303 on the surface of the limit plate 302 to slide on the surface of the limit block 204. After the staff controls the screw slide rail A3 to drive the stop cover 202 to slide out of the pouring chamber 201 through the slider, and removes the stop cover 202.The staff takes out the cement culvert after pouring in the pouring chamber 201, and performs pouring production processing on the next culvert in the same way.
