Technical Field

[0001] The utility model relates to the technical field of slurry proportioning and mixing, in particular to a slurry proportioning device for foundation pit construction. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be decided based on geological and hydrological data and the conditions of nearby buildings on site. The slurry proportioning device for foundation pit construction is a device specially used for foundation pit support and foundation treatment projects. It can mix cement, bentonite, water and other additives into slurry in a specific proportion. This slurry is used in construction processes such as strengthening the foundation, lowering the groundwater level, and preventing soil landslides. The proportioning device usually includes components such as a metering system, a mixing tank, a stirring device, a pumping system and a control system to ensure that the slurry is accurately proportioned and evenly mixed, thereby ensuring the quality and efficiency of construction.

[0003] At present, slurry is mixed with cement, fly ash and stabilizer in a proportioned manner. However, there are some particulate matter in these mixed materials including the slurry. These particulate matter is also part of the mixed materials, but these particulate matter has a certain mass, so the particles are affected by gravity and accumulate at the bottom of the proportioning mixing box. These particles cannot be effectively stirred and mixed, affecting the uniform mixing of the slurry, thereby resulting in the quality of the slurry in subsequent use. Therefore, a slurry proportioning device for foundation pit construction is proposed. Utility Model Content

These particles cannot be effectively stirred and mixed, affecting the uniform mixing of the slurry, thereby leading to the quality problem of the slurry in subsequent use.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: a slurry proportioning device for foundation pit construction, comprising a proportioning mixing box, a drive motor, a rotating shaft, a stirring rod, a discharge pipe and a valve, wherein a particle processing mechanism is provided inside the proportioning mixing box;

[0007] Furthermore, a guide seat is fixedly installed on the inner peripheral wall of the proportioning and mixing box. The guide seat is located on the bottom inner wall of the proportioning and mixing box. The guide seat is annular and has a triangular cross section.

[0008] Furthermore, the distance between the outer walls of the two arc-shaped grinding plates on the opposite sides is the same as the minimum inner diameter of the inner peripheral wall of the guide seat.

[0009] Furthermore, the outer wall of the connecting shaft is provided with two adjustment slots, the limit block is slidably connected inside the adjustment slots and is adapted in size, and the bottom of the connecting shaft is rotatably connected inside the base.

[0010] Furthermore, the two arc-shaped grinding plates form a semicircular grinding plate, the lowest height to which the two arc-shaped grinding plates can move downward is the same as the height of the inner wall of the bottom of the proportioning mixing box, and the distance between the outer walls on opposite sides of the two arc-shaped grinding plates is greater than the diameter of the base.

[0011] Furthermore, the driving motor is fixedly mounted on the top of the proportioning and mixing box, the rotating shaft is fixedly mounted on the output shaft of the driving motor and is located inside the proportioning and mixing box, there are six stirring rods and they are fixedly mounted on the outer peripheral wall of the rotating shaft, the discharge pipe is fixedly mounted on the bottom of the proportioning and mixing box, and the valve is sleeved on the outer peripheral wall of the discharge pipe.

The two arc-shaped grinding plates 14 form a semicircular grinding plate. The lowest height to which the two arc-shaped grinding plates 14 can move downward is the same as the height of the bottom inner wall of the proportioning and mixing box 1. The distance between the outer walls on the opposite side of the two arc-shaped grinding plates 14 is greater than the diameter of the base 15.
