A roadbed lime soil automatic mixing and spreading machine

Abstract

The invention provides an automatic mixing and dispensing machine for roadbed lime-clay. The automatic mixing and dispensing machine for the roadbed lime-clay effectively solves the problems that prior roadbed lime-clay backfill operating technology needs excessive equipment, the ratio of components in the roadbed lime-clay is hard to control, humidity of the lime-clay cannot be controlled, constructing environment is poor, and efficiency is low. The automatic mixing and dispensing machine for the roadbed lime-clay comprises a towing tractor, a frame is arranged on the towing tractor, and a water tank is arranged on the frame; a first water pipe, a second water pipe and a third water pipe are arranged below the water tank; a mixing device located on the frame is arranged below the first water pipe, a buffering device is arranged at the right side of the mixing device, a humidifying device is arranged at the left side of the mixing device, a spreading device is arranged at the left side of the humidifying device, and a raised dust prevention device is arranged at the left side of the spreading device. the automatic mixing and dispensing machine for the roadbed lime-clay has the efficient and perfect blending function, the working process is simple, time and labor are saved, labor capacity of workers is significantly reduced, the problem of raised dust in the construction site is greatly alleviated, the compositional ratio in the lime-clay backfilling process is effectively controlled, engineering constructing efficiency is greatly improved, engineering quality is improved, so that lime-clay backfilling becomes convenient, fast, simple and easy to conduct.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an automatic mixing and spreading machine for roadbed lime soil. Background technique [0002] Lime soil is made by uniformly mixing clay and slaked lime powder according to a certain ratio, and the composition is mostly 2:8 or 3:7. Lime soil is widely used in roadbed construction, which can improve the tensile and shear strength of the road surface and significantly increase the life of the road surface. [0003] At present, most of the construction sites are carried out step by step by spreading, mixing, watering and rolling, which is not suitable for the rapid construction of buildings or paving. During construction in the prior art, in the backfilling operation of excavating the foundation, slaked lime powder and appropriate water are spread layer by layer, and then the agricultural cultivator is used for mixing, and rolling is carried out after mixing evenly. The...
