Problems solved by technology

[0002] With the continuous development of my country's railway technology, mechanized maintenance of ballasted railways has been a long-standing railway policy in my country. However, due to the construction technology of large-scale railway maintenance machinery in my country, it has been developed on the basis of introducing foreign technology. At present, It is mainly used in the grid plate structure of the sieve cleaning machine. The main components are all castings, the processing cost is high, and there are many weak links in actual use, the service life of the components is short, and the replacement rate is high.

Abstract

The invention relates to the technical field of railway maintenance equipment, in particular to a scrabbling plate device for loosening and excavating the railway ballast. The scrabbling plate devicecomprises scrabbling plates, link holes are arranged in the lower positions of the scrabbling plates, the scrabbling plates can be linked through an intermediate link board and link pins, the scrabbling palm surfaces of the scrabbling plates are each of a concave structure, scrabbling tooth mounting holes are arranged in the backs of the scrabbling palm surfaces, and scrabbling teeth are arrangedin the scrabbling tooth mounting holes. The scrabbling plate device has the advantages of simple structure, low processing cost and long service life, and the concave structure design of the scrapingpalm parts of the scrabbling plates is more conducive to the retention and movement of the ballast in the scrabbling plates.

Description

technical field [0001] The invention relates to the technical field of railway maintenance equipment, in particular to a scraper device for loosening and excavating ballast on a railway track bed. Background technique [0002] With the continuous development of my country's railway technology, mechanized maintenance of ballasted railways has been a long-standing railway policy in my country. However, due to the construction technology of large-scale railway maintenance machinery in my country, it has been developed on the basis of introducing foreign technology. At present, It is mainly used in the grid plate structure of the sieve cleaning machine. The main components are all castings, the processing cost is high, and there are many weak links in actual use, the service life of the components is short, and the replacement rate is high. Contents of the invention [0003] The present invention aims to solve the above problems, thereby providing a grilling device with simple ...
