Vlasenko I. Decrease of resistance filling of the scraper bucket by employment of the soil track appliance and reasons him rational of parameters.

By object of the scraper bucket, equipped of soil track ap- pliance (STA). The purpose of work is decrease of resis- tance to filling of the scraper bucket and increase efficiency of scraper, for account of use STA. The methods of re- searches and instruments - main rules of theory of soil cut- ting, laboratory installation, equipped tensometric by de- vices, scraper ДЗ-20В, PECM. The signification of received results for theories and practice consists in decision of tech- nical problem of decrease of resistance filling of the scraper bucket and increase of efficiency of scraper at the expense of use of new way of filling of the scraper bucket (branchy of process), by application of soil track appliance. The physical essence of process of filling of the scraper bucket with STA, which consists in branchy of this process. The in- crease of efficiency is justified of law of filling of the scraper bucket and scientifically well-founded the increase of efficiency of scraper with offered design STA. In par- ticular: the mathematical model of process of filling is de- veloped, which is different from by existing accounts of size particle of soil and their distribution; the rational capacity of bucket in dependence on regime digging and transport re- gime is determined; the rational areas of application various intensificators in dependence on parameters of bucket are established; the size decrease of resistance of dragging prism and resistance of cutting at application STA is installed. The main results of work are introduced in development and creation of research sample STA in MMC-50. The area of use - building and road engineering.
