METHOD OF TRANSPORT SERVICE OF SELF-PROPELLED GRAIN AND FORAGE HARVESTERS WITH SYSTEM OF MOBILE MEANS, MAINLY AUTO(TRACTOR) TRAINS Russian patent published in 2014 - IPC A01B59/04 A01D75/30 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to agriculture and can be used for the transport service of grain and forage self-propelled harvesters with loading the harvest to the vehicle in the process of harvesting and delivery of all of the biological harvest to the storage location. On the harvester hook 1 the trailer 3 is towed and it is loaded with the harvest. To the harvester 1 the empty auto(tractor) tractor-trailer 7 is moved and the loaded trailer 3 of the harvester is replaced to the empty trailer 7 without departure of the harvester 1 from the working area. In the process of replacement of the trailers the harvester 1 and the auto(tractor) tractor are stopped so that the empty trailer 7 is located opposite the loaded trailer 3 of the harvester 1. The loaded trailer 3 is transported to the storage area. In the first embodiment, the device for transport service comprises the harvester 1 with towing-hitch mechanism connected to the drawbar 4 of the trailer 3, and the auto(tractor) tractor with a trailer-towing device connected to the drawbar 4 of the trailer 7. The drawbar 4 of each trailer is equipped with a coupling link 8. The towing-hitch mechanism of the harvester 1 is made in the form of a manipulator 9 with gripping for the coupling link 8 of the drawbar 4. In another embodiment of the device for transport service the towing-hitch mechanism of the harvester is made in the form of a winch with a drive and a brake. The winch is provided with the assembly joint located on the end of the cable for connection with the drawbar of the trailer when changing of the loaded trailer to the empty one.

EFFECT: use of the group of inventions increases productivity and technological process reliability of transport service of harvesters.
