COMBING DEVICE Russian patent published in 2020 - IPC A01D41/08 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to combing cones of cereals and fodder crops. Stripping device comprises frame 1, on which cowl 16 is installed, combing drum 2 with cover 5 with openings 7, closed by screen, screw 4, on end sections of which there are spirals of left and right directions of turns. Stripping drum 2 is made in the form of a pipe with cylindrical surface, on which there are combs 3 in staggered order, teeth of which are made in the form of a spoon with a base shaped to a circle sharpened in circumferential direction. Combs 3 are rigidly attached to the pipe or at operation on stony soils they are hinged and spring-loaded to protect the combs and the whole drum from breakdowns. Cover 5 of combing drum 2 at the level of drum axis tightly adjoins surface of rotation of combs 3 of drum with further formation of gap and its increase to create air flow in proportion to its increasing volume according to the principle of fan operation. Drum cover 5 is made in the internal part of rubber-coated grains for softening the impact.

EFFECT: combing device ensures load equalization on combing drum and reduction of failures at operation on stony soils.
