DEVICE AND SYSTEM FOR SUPPLY OF MATERIAL TO PLACE OF ITS APPLICATION AND USE OF SUCH DEVICE AND SYSTEM Russian patent published in 2019 - IPC B05B13/04 A62C33/04 E04G21/04 

FIELD: spraying; pulverisation.

SUBSTANCE: group of inventions relates to a device for supply of hardening and pourable, or blowing, or spraying construction material to a place of its application. Proposed device comprises hose (11) to feed material from material source to operator (13) to manually distribute material at application point by means of device. Device for supply comprises load distribution belt (12) made with possibility of connection with operator (13) and containing one or more connecting devices (15). Device also comprises connector (14) connected to hose (11) and made with possibility of connection with one or more connecting devices (15) of load distribution belt (12) to obtain hinged connection between belt (12) and hose (11) so that hose (11) rests on operator (13) through hinged connection, when operator (13) controls device (10) for distribution of material in place of its application. Besides, the device comprises flexible tube (18) connected to hose (11). Hose (11) is located between material source and flexible tube (18). Flexible tube (18) is more flexible than hose (11). System for supply of hardening and transferable, or blowing, or spraying construction material to place of its application comprises device, which contains first load distribution zone (12a), used by first operator (13a), laying material in place of its application. System comprises second load distribution belt (12a) used by second operator (13b), control position of part of hose (11), and appliance with connector (14) for connection with connection device (15) of second load distribution belt (12b). Device and system for supply of hardening and transferable, or blowing, or spraying construction material to place of its application are used for distribution of hardening building material on surface by pumping, or blowing, or spraying.

EFFECT: technical result of the group of inventions is improved working conditions and reduced risk of musculoskeletal injuries for at least one of the operators.
