Stone crusher for railway construction system provided with dust reducing mechanism

Abstract

The invention relates to the field of stone crushers in railway construction systems, in particular to a stone crusher for a railway construction system provided with a dust reducing mechanism. The stone crusher comprises a transmission structure, a screening structure, a dust preventing structure, a dust removing structure and a sealing structure; the dust removing structure is arranged in the transmission structure; when sandy stones are crushed, water currents are adopted for wet dust removal again, so that dust in the crushing process is quickly settled; meanwhile, primary-crushed small sand particles are conveniently stored in the dust removing structure, so that the influence on the railway pavement by nonuniform crushing of the sandy stones in secondary crushing of small sand particles is prevented; through arrangement of the dust removing structure, a sandy stone blockage preventing effect is achieved, so that the discharge effect of crushed sandy stones is better; and the screening structure for screening the sandy stones is arranged in the transmission structure, so that the sandy stones are conveniently screened during crushing, the space utilization efficiency and the sandy stone crushing efficiency and quality are greatly improved, and meanwhile, the secondary dust rise is prevented.

Description

technical field [0001] The invention relates to the field of stone crushers in railway construction systems, in particular to a stone crusher provided with a dust reduction mechanism and used in railway construction systems. Background technique [0002] With the rapid development of society, railway transportation has become one of the main modes of transportation. Railways are the tracks for trains and other means of transportation. The gravel under railway sleepers is usually called gravel. The main function of gravel is to disperse the load borne by sleepers The pressure prevents the sleepers from sinking easily. At the same time, the stone slag is easy to adjust the height of the sleepers to keep the rail surface flat. It has good water permeability and wind and rain resistance. It also has the effect of buffering the vibration of the train. The stones of the railway are mostly processed by the crocodile crusher Crushing, and then use the sieve to screen the crushed san...

Problems solved by technology

[0003] However, most of the motor and other electrical components of the traditional crocodile crusher are exposed outdoors. Long-term use is likely to cause sand and gravel jams. The motor itself accumulates dust, which affects the performance of electrical components. At the same time, the dust is large during the crushing process. During the wet crushing process after the marble is watered, dust will still be generated at the moment of crushing. The dust will easily affect the health of the operator. At the same time, the sewage after the marble is poured is not easy to handle. Due to the hardness of the marble during the crushing process, it is easy to get stuck. It is plugged in the inside of the crushing equipment, which affects the discharge of the crushed sand. When the crushed sand continues to be crushed, the uniformity of the crushed sand will vary greatly, which will affect the laying effect. At the same time, the crushed stone needs to be used Screening equipment for secondary screening wastes a lot of manpower and material resources and takes up space, and it is easy to cause new dust
