The fluidized solidified soil falls into the first groove of the discharge plate in the through groove. The discharge plate is rotatably connected to the box A through a pin shaft, and the inclination angle of the discharge plate can be adjusted, thereby realizing the adjustment of the discharge speed of the solidified soil.

[0038] By adopting the above technical solution, the motor A6 can drive the connecting shaft to rotate, thereby driving the rotating shaft 12 to rotate. Through the active rotation of the rotating shaft 12, the crushing effect of the stirring rod 11 is increased.

[0039] In some other embodiments of the present application, in order to achieve the effect of accurately backfilling the soil, devices such as a second groove 13 and a fixing block 16 are also provided.

[0040] Specifically, a second groove 13 is provided on the other side of the interior of the box body A1, a fixed block 16 is installed on the other side of the outer surface of the box body A1, an electric push rod A14 is installed on the upper end surface of the fixed block 16, a pressure plate 15 is fixedly connected to the lower end surface of the electric push rod A14, a U-shaped plate 17 is installed below one side of the outer surface of the fixed block 16, a horizontal groove 21 is provided below the second groove 13, a vertical groove 29 is provided on the lower end surface of the fixed block 16, slots 19 are provided below both sides of the inner wall of the vertical groove 29, and the inner side of the slot 19 is connected to a baffle 20 through an electric push rod B18.

[0042] By adopting the above technical solution, the solidified soil in the box B4 enters the through groove 3 through the guide groove A, and the solidified soil in the box B4 enters the second groove 13 through the guide groove B, and then enters the vertical groove 29 through the connecting groove.

[0043] One of the electric push rods B18 is fixedly connected to the U-shaped plate 17 , and the other electric push rod B18 is fixedly connected to the transverse groove 21 via a circular groove. The baffle 20 is matched with the transverse groove 21 and the U-shaped plate 17 .

[0047] When the device for backfilling the solidified soil around the deep foundation pit is in use, the solidified soil is added into the box body B4 through the feed hopper. During the whole backfilling process, the stirring rod 11 can continuously stir the solidified soil in the backfilling device, so that the fluid solidified soil can maintain fluidity, thereby achieving a better backfilling effect. The solidified soil falls into the inner side of the second groove 13 of the unloading plate 2. By controlling the switch of the motor B8, the motor B8 drives the short shaft to rotate, and the rotation of the short shaft drives the pin shaft 22 to rotate, thereby driving the unloading plate 2 to rotate, thereby adjusting the unloading speed of the solidified soil. When the pin shaft 22 rotates, it drives the horizontal shaft 24 to rotate, thereby driving the gear 23 to rotate. After the unloading plate 2 is adjusted to a suitable angle, the motor B8 is controlled to rotate. The switch of the push rod C28 causes the block 25 to be stuck in the tooth groove of the gear 23, limiting the gear 23, thereby limiting the horizontal axis 24 and the pin shaft 22, preventing the feed plate 2 from rotating during the backfilling process and affecting the feed speed. When precise backfilling is required, the switch of the electric push rod B18 can be controlled to retract the baffle 20 into the horizontal groove 21 and the U-shaped plate 17, and the solidified soil in the vertical groove 29 falls from the gap between the two baffles 20 and falls into the soil pit, achieving the effect of precise backfilling of the soil. The utility model can adjust the feed speed of the solidified soil by providing the feed plate 2, and can achieve the effect of precise backfilling of the soil by providing the fixed block 16, and is easy to use.
