UNIT FOR SELECTIVE HARVESTING OF VEGETABLES, MELONS AND GOURDS Russian patent published in 2011 - IPC A01D45/00 A01D46/00 

FIELD: agriculture.

SUBSTANCE: unit comprises a central section with support wheels, horizontal side sections, carrying conveyor webs of closed chain contours, a conveyor belt, braces, hydraulic cylinders and a drive. At the same time the central section, acting as a loading conveyor, and side sections with a drive and braces are mounted on the rear suspension system of a tractor with the help of a support frame. The central section is a double-stream conveyor with fruit-picking blades, having an elastic partition in the middle part. The inclined part of the loading conveyor is coupled with the sections, and the horizontal part - with a fruit layer. The sections are side chute conveyors with a single-chain drive. In the middle part of the sections there is a hinged joint and a support stand with a self-centring wheel. The chute conveyors have a hinged-rotary fixation to a support frame and are mounted in bearing girders retained by ropes. The girders are made of corner sides, which fix the chute conveyor position with support and thrust rollers. Each chute conveyor is made of elastic material fixed to metal arcs, connected to the driving chain links. In the middle part of the bearing girder there is a guiding path that serves a support for a driving chain. In the lower part of the middle section there is a sloping chute to lay fruit into a roll. All working elements of the unit are driven by a power takeoff shaft via a reducer.

EFFECT: increased efficiency, process reliability and simplified technology.
