Figure 1 and Figure 2 As shown, the transmission rod 8 at the lower end and the spiral rod 5 for limiting the flow state of the liquid can be supported by the second fixing frame 11;

[0027] In this embodiment, if Figure 1As shown, second stirring rods 9 are arranged on both sides of the first stirring rod 3, and the upper ends of the two second stirring rods 9 are fixedly connected by a second transmission ring 21, and a fourth fixing frame 15 is arranged on one side outside the second transmission ring 21, and the fourth fixing frame 15 and the housing 1 are an integral structure, and the fourth fixing frame 15 and the second transmission ring 21 are rotatably connected by a second bearing 24, and the second stirring rod 9 can be suspended and fixed by welding and fixing the fourth fixing frame 15 and rotating connection of the second bearing 24, so as to avoid restricting the subsequent rotation of the second stirring rod 9;

[0030] Working principle: when using the device and paving the construction location, the material is first put into the shell 1, and the stirring is completed by rotating the second stirring rod 9 and the first stirring rod 3. The lateral movement of the equipment is achieved by moving the mobile frame 2. During the movement, the second motor 14 is started, and the output shaft of the second motor 14 drives the first gear 19 to rotate. The rotation of the first gear 19 can drive the first transmission ring 17 to rotate through the first tooth groove 18. The first transmission ring 17 can drive the connecting piece 6 to rotate through the extension piece 7 and the transmission rod 8. The rotation of the connecting piece 6 can drive the spiral rod 5 to rotate, and the valve 4 is opened. After the valve 4 is opened, the material inside the shell 1 will slide down due to gravity. During the sliding process, it will be pushed by the clockwise rotating spiral rod 5 and will be restricted by the counterclockwise rotating spiral rod 5, thereby limiting the falling speed of the material and adjusting the required paving requirements by rotating the direction.
