Soil crushing and mixing device for road construction and use method thereof

Abstract

The invention discloses a soil crushing and mixing device for road construction and a use method thereof. The soil crushing and mixing device comprises a pretreatment feeding mechanism, a crushing and stirring mechanism, a weighing mechanism, a turning and mixing mechanism and a storage bin which are sequentially arranged on a rack. The pretreatment feeding mechanism is used for pretreating to-be-crushed soil. The crushing and stirring mechanism is used for crushing and stirring the pretreated soil. The weighing mechanism is used for weighing other quantitative powder materials required by road construction and conveying out the weighed powder materials. The turning and stirring mechanism is used for turning and stirring the crushed soil and the weighed powder materials. The storage bin is used for accommodating and storing the soil and the powder materials which are finally and uniformly turned and mixed. The soil crushing and mixing device for road construction is provided with the pretreatment feeding mechanism, large stones, large soil blocks and the like in soil can be screened and removed in the feeding process, the situation that the large stones enter a pretreatment hopper and damage equipment is avoided, the difficulty of later soil crushing operation is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a soil crushing and mixing device for road construction and its application method. Background technique [0002] Entering the new era, with the great change of the national development concept, the intensity of environmental protection has increased unprecedentedly, and the emphasis on environmental protection in all walks of life has reached an unprecedented height; as the basic guarantee industry for the development of the national economy, road construction has also Entering a new round of great development period, under this background, optimizing and innovating road construction technology has become a major issue in the industry. Based on this, the construction technology and equipment used for road construction bottom stabilized soil need to be improved and optimized. At present, road bottom The construction process of stabilized soil includes the following steps: soil extraction - ginseng powder (cement, lime) - paving...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a soil crushing and mixing device for road construction and its use method, so as to solve the problem that the soil crushing and mixing device proposed in the background technology is rarely equipped with a pretreatment feeding mechanism and a turning mechanism at the same time, and cannot be screened out. Large clods and rocks in the soil are not only easy to damage the equipment, but also increase the difficulty of the later crushing operation and increase the cost; due to the accumulation of powder and soil thicker, if there is no pre-mixing, and the direct turning Mixing, it is easy to have uneven and incomplete mixing, which requires secondary rework, which is time-consuming and labor-intensive.
