Through the above setting, the cooperation between the material transfer column 63 and the discharge tank 21 can ensure that the amount of concrete in the pre-storage groove 64 remains within a certain value after the material transfer column 63 rotates.

[0021] Work flow: when pouring concrete, first feed, fill the inside of the storage tank 32 with concrete, at this time the cover plate 4 is in an open state, canning concrete into the inside of the storage tank 32, due to the sealing of the rubber sealing ring 38 between the push disc 37 and the storage tank 31, it can prevent concrete from flowing out between the push disc 37 and the storage tank 31, until the concrete is located at a distance of ten centimeters below the lower end of the rubber pad 33, then place the cover plate 4 on the upper end of the storage tank 31, fix the cover plate 4 with the storage tank 31 by screws 5, seal between the cover plate 4 and the storage tank 31 by the storage tank 32, at this time the concrete flows into the inside of the pre-storage groove 64 through the discharge port 39 and the upper through groove 26, due to the gap cooperation between the material transfer column 63 and the material transfer groove 25, and the gap cooperation between the material transfer column 63 and the two partitions 28, so that the concrete flowing out from the gap between the material transfer column 63 and the discharge tank 21 is minimal, when pouring concrete, start the servo motor 22 to drive the worm 23 to rotate, the worm 23 rotates in the inside of the discharge tank 21, the worm 23 drives the engaged turbine 62 to rotate, the turbine 62 drives the built-in shaft 61 and the material transfer column 63 to rotate, the built-in shaft 61 rotates in the inside of the inner rotating plate 24 through the bearing, the connection between the worm 23 and the turbine 62 can prevent the built-in shaft 61 from rotating, in the process of rotating the material transfer column 63, the upper through groove 26 of the discharge tank 21 is scraped to remove the concrete at the upper end of the pre-storage groove 64 and store it in the inside of the upper through groove 26, so as to ensure the amount of concrete in the inside of the pre-storage groove 64, when the pre-storage groove 64 filled with concrete is behind the lower through groove 27, at this time the concrete will fall from the inside of the pre-storage groove 64 to the road surface, so as to ensure the amount of concrete poured at a time, and thus control the uniformity of the concrete pouring effect; When the amount of concrete inside the storage tank 32 is reduced and the flow speed is slow, the multi-stage electric hydraulic rod 36 is started to drive the push disc 37 to move to the right. At this time, the air inside the push groove 34 at the right end of the push disc 37 will flow out through the groove of the support disc 35. At this time, the external air will enter the inside of the storage tank 32 and the push groove 34 through the upper through hole 7 and the inside of the check valve 8. Since the check valve 8 has the effect of controlling the one-way flow of gas, the gas inside the storage tank 32 cannot flow out from the check valve 8. Therefore, when the push disc 37 is controlled to move to the left by the multi-stage electric hydraulic rod 36, the gas inside the storage tank 32 expands. Through the expansion effect, the concrete inside the storage tank 32 will quickly flow into the pre-storage groove 64 in order to reduce the occupation of the internal space of the storage tank 32. In this way, not only the control of the flow speed of the concrete and the control of the speed of the canning are increased, but also the concrete filled in the pre-storage groove 64 can be ensured to have no gaps, further improving the uniformity of the canning. After the canning is completed, the push disc 37 is controlled by the multi-stage electric hydraulic rod 36 to move to the left all the time. Through the push disc 37 and the rubber sealing ring 38, the concrete on the inner wall of the storage tank 32 is scraped off, so that the concrete on the inner wall of the storage tank 32 is quickly discharged from the discharge port 39, and at the same time, the effect of cleaning the inside of the storage tank 32 is achieved. In this way, the convenience of the staff for cleaning the inside of the device is improved, and the workload is reduced.
