Description

Technical Field

[0001] The utility model belongs to raw material screening equipment for lime soil roadbed construction, in particular to a raw material screening device for lime soil roadbed construction. Background Art

[0002] Lime soil roadbed is a roadbed structure that uses lime materials to improve soil. This type of roadbed is commonly found in infrastructure projects such as highways, railways, and airports, and is used to improve the bearing capacity, stability, and durability of the roadbed. In the construction of lime soil roadbed, raw material screening is an important step. By screening the raw materials, the appropriate size and quality of soil particles can be ensured, thereby improving the stability and bearing capacity of the roadbed. Raw material screening is usually carried out using a screening machine, which can effectively screen and classify the raw materials to meet the needs of raw materials of different particle sizes in roadbed projects; According to Chinese patent application number: 202322238773.0, a method for the construction of lime soil roadbed is disclosed. The raw material screening device relates to the technical field of screening raw materials mixed with ash and soil, and comprises a shell, a crushing sleeve is rotatably connected to the inner wall of the shell, a driving shaft is fixedly connected to the inner wall of the crushing sleeve, a bracket is provided on the outer wall of the left end of the shell, and the driving shaft is connected to the driven shaft through a belt drive. When the raw material enters the cavity, the upper end crushing sleeve preliminarily crushes the agglomerated raw material through a rack, and agglomerates of different sizes can be uniformly crushed into broken pieces. When the screen rotates, the broken raw materials on the surface of the screen are squeezed by the crushing sleeve into raw materials with standard sizes. In this way, the raw materials that are incompletely crushed and missed after the upper end is crushed can be completely crushed, which saves cost and time.

[0003] The existing technology effectively solves the problem that the screening machine lacks the function of crushing the agglomerated raw materials and the screened raw materials are easily accumulated on the filter surface. It has the advantages of being able to crush the agglomerated raw materials and reduce the accumulation on the filter surface. However, in actual use, although the crushing sleeve can crush larger plate sediment, the crushing sleeve is likely to compact the sediment into the filter holes, which can easily cause the filter to become blocked and affect the screening efficiency.
