SELF-PROPELLED MACHINE Russian patent published in 2021 - IPC A01B51/02 

FIELD: agriculture.

SUBSTANCE: present invention relates to a self-propelled machine for agriculture having load-bearing structure (T), which accepts various attachments and has at least one drive unit (3) having control module (4). The load-bearing structure is mounted on supports (B, B') on the ground at the end, and it forms an agricultural portal system with at least one main load-bearing element (6) designed to perform various work tasks. The portal system can be converted from a road position with a width for driving on the road (size FB) to a working position with a significantly larger working width (AB). The load-bearing structure (T) contains corresponding side load-bearing elements (ST, ST') containing supports (B, B') to the ground. The load-bearing structure, which has a longitudinal orientation in the road position, has a vertical longitudinal central plane (M) in a zone of its two supports (B, B') to the ground at its end passing between them. Functional frame (FR, FR') located in a spatial orientation relatively to it, having asymmetric main load-bearing element (6'), is proposed as the load-bearing structure. In accordance with the present invention, main load-bearing element (6), based on the size (FB) of the possible width when driving on the road, in the outer third (TD, TD') of the specified size (FB) is connected to at least one side load-bearing element (ST, ST').

EFFECT: invention will increase the universality of the machine for agricultural application and corresponding phases of transportation by road.
