the present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a sectional view of a front view of the present invention.

Fig. 2 is a plan view of the present invention.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the following embodiments:

the mixer for uniformly mixing the improved soil as shown in fig. 1 and 2 comprises a mixer case 1, a motor control box 3, a driving motor 4, a mixing rod main shaft 5, an upper flat mixer 6 and a lower claw mixer 7, the driving motor 4 is fixedly arranged at the bottom of the stirrer box body 1, the stirring rod main shaft 5 is rotatably arranged on the bottom wall of the stirrer box body 1, the stirring rod main shaft 5 is connected with an output shaft of the driving motor 4 through a transmission mechanism, the upper flat plate type stirrer 6 and the lower claw type stirrer 7 are fixedly arranged at the upper part and the lower part of the stirring rod main shaft 5, the upper flat plate type stirrer 6 is of a flat plate-shaped structure, and the upper flat plate type stirrer 6 is used for primarily smashing and dispersing soil (raw materials) and additives, so that the purpose of primary mixing is achieved, and most of the additives are prevented from being retained at the same position. The flat plate is slightly twisted according to the aerodynamic principle, so that the stirrer is enabled to make a small airflow with a downward direction when rotating, soil on the screen is subjected to downward air pressure, the situation that fine particles in soil materials and additives are blown out of the lower part of the stirrer can be guaranteed, stirring claws on two sides of the claw-shaped stirrer 7 are obliquely arranged towards the stirring rod main shaft 5, the claw-shaped structure of the lower claw-shaped stirrer 7 is similar to that of the existing cement stabilized dirt road mixer, and soil can be effectively mixed and improved. The claw-shaped structures on the left side and the right side of the claw-shaped stirrer are staggered with each other, so that a better stirring effect is ensured; in order to prevent the unbalance stress of the main shaft, the left and right moments are consistent by arranging the block body with certain mass at the right side supporting rod. The fixed setting in 1 outside of agitator box 3 of motor control box, motor control box 3 is connected to driving motor 4 through the circuit, and motor control box 3 controls driving motor 4's switch and stirring speed, 1 top of agitator box is provided with water inlet 11, 11 internal connection showerheads of water inlet, and the external connection water pipe sets up water gauge and accuse water valve on the water pipe, and the valve control velocity of flow, water gauge record velocity of flow and total inflow, 1 bottom of agitator box is provided with discharge gate 10, discharge gate 10 uses puddler main shaft 5 to set up two as central symmetry, discharge gate 10 passes through the sealed shutoff of shrouding, the shrouding is rotated and is installed on the diapire of agitator box 1, 1 bottom of agitator box is provided with the action bars, can open the shrouding of shutoff discharge gate easily through the action bars.

The bottom of the stirrer box body 1 is fixedly provided with supporting legs 2 which are used for stabilizing the stirrer, and the bottom of the stirrer box body is provided with a damping spring to reduce vibration and noise.

The upper flat plate type stirrer 6 and the lower claw type stirrer 7 are arranged perpendicular to each other, and the stirring claws at both sides of the lower claw type stirrer 7 are directed clockwise toward the upper flat plate type stirrer 6.

The top of the stirrer box body 1 is provided with an annular accepting platform 9, the annular accepting platform 9 is provided with a screen 8, the annular accepting platform 9 is used for accepting the screen 8, the screen 8 is ensured not to fall into the stirrer box body 1, the screen 8 can be conveniently placed and taken out, the screen 8 is used for preliminarily dispersing soil blocks, when the materials are fed, the soil materials and the mixture firstly pass through the screen and then are rotationally beaten by a flat plate stirrer on the upper part, and the flat plate stirrer can play the roles of preliminarily mixing, dispersing soil (raw materials) and additives. Meanwhile, the screen can prevent the flat-plate stirrer from throwing the soil (raw materials) out of the stirrer. If no screen is arranged, the soil material directly enters the bottom of the box body, and the flat plate type stirrer is not ready for preliminary mixing. Screens with different calibers can be replaced according to specific conditions. The screen is a specially-made screen, and the net-shaped structure is formed by interlacing vertical steel sheets with the thickness of about 2-3mm, so that the rigidity and the bearing capacity of the screen are ensured.
