When the mixing vehicle body 1 moves forward or backward, the raw materials in the inner cavity of the mixing box 4 tend to be stable under the multiple buffering and shock absorption of the front end buffer assembly 10, the rear end buffer assembly 11 and the first hydraulic damper 12, so that the mixing box 4 is buffered and shock-absorbed. A reversible vibrating screen is provided on the upper part of the inner cavity of the hopper box 6, and the reversible vibrating screen allows the materials on it to be flipped and put into the inner cavity of the mixing box 4 for mixing.

[0023] Specifically, the mixer body 1 is the main structure of the entire mixer truck and carries all components. The L-shaped chassis 2 provides a stable basic platform for installing key components such as the mixing box and the reducer. The mixing box 4 is installed on the top of the L-shaped chassis, and a mixing shaft is provided inside for mixing raw materials. The reducer 5 connects the motor and the mixing shaft to adjust the mixing speed to ensure uniform mixing. The hopper box 6 is used to store the raw materials to be mixed and is equipped with a flip-type vibrating screen to facilitate the raw materials to enter the mixing box.

[0024] Specifically, the front-end buffer assembly 10 includes a buffer box 9 fixedly mounted on the inner wall of the longitudinal vertical plate of the L-shaped chassis 2, a second hydraulic damper 16 movably mounted in the inner cavity of the buffer box 9, and a buffer shock-absorbing abutment plate 14 fixedly mounted on the damping end of the second hydraulic damper 16, the buffer shock-absorbing abutment plate 14 abuts against the outer wall of the second support frame 8, a plurality of air spring components 19 are symmetrically and laterally installed in the inner cavity of the buffer box 9, and a shock-absorbing support plate 15 is fixedly connected to the free end of the air spring component 19, so that the shock-absorbing support plate 15 moves in the inner cavity of the buffer box 9 for buffering under the driving buffering of the air spring component 19.

A compression spring 21 is sleeved on the circumference of each third hydraulic damper 20. The buffer damping end of the third hydraulic damper 20 and the elastic free end of the compression spring 21 are elastically abutted against the outer wall of the first support frame 7. The bottom surfaces of the mixing box 4, the first support frame 7 and the second support frame 8 are all installed on the top surface of the L-shaped chassis 2 by bolts, and a rubber buffer pad is filled between the bottom surfaces of the mixing box 4, the first support frame 7 and the second support frame 8 and the top surface of the L-shaped chassis 2.

[0027] The multiple buffer shock absorption system effectively reduces vibration, improves mixing efficiency and raw material mixing quality, and ensures stable mixing. Even when driving on uneven roads, it can keep the raw materials in the mixing box stable, avoid separation or agglomeration of raw materials, reduce vibration wear on various parts of the mixer truck, and extend the service life of the equipment.

[0028] The hopper box 6 size corresponds to 35 excavator, 60 excavator, 120 excavator, 160 excavator, 200 excavator, 220 excavator, 240 excavator, 270 excavator, 300 excavator, 400 excavator and 450 excavator bucket capacities.

[0029] Working principle: The mobile fluidized solidified soil mixer truck with batch weighing has a front buffer component 10 and a rear buffer component 11 installed at the front and rear of the mixing box, respectively. The first hydraulic damper 12, the buffer box 9, the air spring component 19 and other components are used to effectively absorb the impact force from the front or rear to maintain the stability of the mixing box. The first hydraulic damper 12 and the second hydraulic damper 16 slow down the vibration of the mixing box in the horizontal direction, and produce a damping effect through liquid flow to suppress vibration transmission. The air spring component 19 and the compression spring 21 provide elastic support in the vertical direction to absorb vertical vibration and ensure the smooth operation of the mixing box. The raw materials enter the mixing box 4 through the hopper box 6. The reversible vibrating screen ensures that the raw materials enter evenly. The reducer 5 controls the rotation of the mixing shaft to mix the raw materials. At the same time, the front buffer assembly 10 and the rear buffer assembly 11 start to work. The shock-absorbing support plate 15, the air spring component 19 and the first hydraulic damper 12 work together to absorb and disperse the vibration from the road surface to ensure a smooth mixing process. During the driving process of the vehicle, the first hydraulic damper 12 and the second hydraulic damper 16 continue to work to reduce the horizontal vibration of the mixing box 4; while the air spring component 19 and the compression spring 21 handle the vertical vibration to ensure that the raw materials inside the mixing box are not affected and the mixing quality is maintained. After the mixing is completed, the mixer truck arrives at the destination and controls the reverse rotation of the mixing shaft to discharge the fluidized solidified soil from the mixing box 4.
