Description

Technical Field

[0001] This utility model belongs to the field of civil engineering and building materials technology, specifically relating to a mobile intelligent mixing equipment for fluidized solidified soil on site. Background Technology

[0002] In the field of civil engineering, fluidized solidified soil is an important building material that can be used for backfilling in building trenches or other locations. It can replace conventional backfill soil and does not require compaction, which is very convenient. The traditional mixing process of fluidized solidified soil often relies on mixing plants or manual operation, which has problems such as low efficiency or high transportation costs. In addition, due to the high viscosity of fluidized solidified soil, it is easy for it to adhere to the inner wall of the mixing tank during the mixing process of conventional mixing equipment, resulting in unstable mixing quality. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a mobile intelligent mixing equipment for fluidized solidified soil on site.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A mobile intelligent mixing equipment for fluidized solidified soil includes:

[0006] A mixing tank, wherein a top cover is detachably connected to the top of the mixing tank, the top cover is provided with a feed inlet and a water inlet pipe, and a discharge outlet is provided at the bottom of the mixing tank;

[0007] A stirrer is located inside the mixing tank, and the main shaft of the stirrer extends upward from the top cover and is connected to a drive device.

[0008] The agitator includes connecting rods and scrapers. Two scrapers are symmetrically distributed about the main axis of the agitator and extend along the generatrix of the inner wall of the mixing tank. The scrapers and the main axis of the agitator are fixed together by at least two connecting rods.

[0009] Preferably, the scraper is a columnar structure adapted to the mixing tank, and the connecting rod is connected to the scraper via an elastic element.

[0010] Preferably, an annular mounting plate is provided above the mixing tank, and the top cover is fixed to the mounting plate by bolts;

[0011] The top cover has a notch on its side to serve as a feed inlet, and a flap is hinged to the feed inlet.

[0012] Preferably, the water inlet pipe is disposed on the top cover, and an electromagnetic control valve is provided on the water inlet pipe;

[0013] The mixing tank is equipped with a spiral feeding device on its side. The discharge end of the spiral feeding device extends toward the inlet. The spiral feeding device is driven by a stepper motor.

[0014] Preferably, a support frame is provided above the top cover, and the support frame is fixed to the mounting plate by feet to support the drive device.

[0015] Preferably, the elastic element is a rubber column.

[0016] Beneficial effects: The close contact between the scraper and the inner wall of the mixing tank allows for the scraping of material from the tank wall through rotation, thus ensuring the stability and consistency of the mixing quality. The scraper is connected by an elastic element, which allows it to maintain a close contact with the inner wall of the mixing tank. Furthermore, the elastic element allows the scraper to deform and pass through the resistance point when it encounters large resistance during use, avoiding the reduction in equipment life caused by the scraper being subjected to hard force.
