Description
Technical Field

[0002] With the development of railway transportation, the requirements for the stability and durability of sleepers are constantly increasing. Cold anchoring of sleepers is an important way to fix sleepers. The use of mixing equipment can ensure that materials such as anchoring agents are fully and evenly mixed, making the sleeper anchorage more firm, improving the stability and safety of the line, and reducing railway failures and safety hazards caused by problems such as loose sleepers.
[0003] Mixing equipment is typically powered by a motor, which transmits power to a mixing shaft via a transmission. Driven by the motor, the mixing shaft rotates at high speed. Various stirring components, such as blades and paddles, are mounted on the shaft. These components rotate as the shaft rotates, stirring the material. When materials such as anchoring agents are added to the mixing vessel, the high-speed rotation of the stirring components creates shear, impact, and friction forces on the material. The shear force disperses the different components in the material, the impact force causes collisions between the material particles, and the friction helps to renew and mix the surface of the material particles. Through these actions, the material is fully and evenly stirred in a short period of time.
[0004] However, most mixing equipment does not have the function of automatic loading, and still needs to be manually proportioned and then poured into the feed hopper into the mixing drum. The anchoring agent is usually in powder form and is easy to float when pouring, which reduces the total amount of well-proportioned anchoring agent and reduces its strength after solidification. In addition, materials such as anchoring agents are easy to adhere to the mixing container and mixing parts, which increases the maintenance workload of the equipment and affects the mixing quality of the next use.

[0031] Rotating the rotating block 26 causes the external threaded column 27 to move up and down, thereby driving the L-shaped plate 23 fixed thereto to move up and down, so that the position of the limit plate 22 inside the proportioning box 21 can be adjusted. The capacity of the anchoring agent or water that can be stored between the limit plate 22 and the bottom end of the proportioning box 21 can be clearly determined according to the scale 20 pointed to by the pointer 28 on the corresponding L-shaped plate 23.
