FIELD: building machines. SUBSTANCE: the mixer uses muscle force; it is intended for use mainly on objects where there is not electric power supply or its supply is unsuitable. The feet can transmit power exceeding that by the hands by 3 to 5 times; therefore the drive is accomplished by the worker's feet. The drum rotation drive is made in the form of two pedals connected through links to unidirectional rotating mechanisms; to provide the continuity of the drum rotation cycle, the pedals with links are furnished with a locking link in the form of a two-arm lever. EFFECT: improved design. |
