SEED EXTRACTOR FROM THE PUMPKIN FRUITS Russian patent published in 2018 - IPC A23N4/24 

FIELD: agriculture; machine building.

SUBSTANCE: invention refers to agricultural machinery, in particular to the machines, which are intended for the processing of pumpkin fruits. Seed separator comprises the frame, the drive, the hopper, the knife with the guide, the locking mechanism, which contains the lower and upper conveyors, the working branches of which move in the same direction and at the same speed, the water supply unit and the drip tray for collecting the separated seeds. Upper conveyor is designed in order to fix several halves of fruits on the lower conveyor and its working branch is spring-loaded with the copying rollers. Lower conveyor consists of a plurality of transport cells including the rigidly fixed conveying rods and the support rods, which are freely rotating in the tines. Support rods are made in the form of the cranked axis and form the supporting surface for the halves of the fruit. Water supply unit contains two narrow nozzles. Nozzles are installed under the working branch of the lower conveyor and are connected to the pumping station by the water supply pipeline. In the water supply line there is the water flow control valve, which is communicated by the system of levers with the copying rollers of the upper conveyor. Lower conveyor is made in the form of the closed chain contour, which is mounted on four shafts. Working branch of the contour, which is located between the upper shafts, serves as the supporting surface for the halves of the fruit. Non-working branch of the contour between the lower shafts moves below the level of the seed collection tray.

EFFECT: use of the invention will allow to reduce the loss of seeds, when they are separated from the pumpkin fruit.
