SU1542466A1 - Appliance to grain harvester for harvesting sunflower - Google Patents

Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce the loss of grain and stems. The adaptation to the combine harvester for the harvesting of sunflower comprises an upper cutting apparatus, made of left 3 and right 4 parts relative to the longitudinal axis of the combine, with the possibility of their counter-rotation. Shafts with knives 6 and cutting elements 12 mounted on them are fixed on comb 2. Element 12 is installed to form a 90 ° C angle between its edge and the straight line connecting the middle of the front side of the conveyor 13 and the middle of this edge. On the non-working side of the knives 6, perpendicular to the plane of their rotation, flexible strips are installed. Under the upper cutting apparatus, intended for cutting sunflower baskets, there is a segment-finger cutting apparatus, which provides a double cut of the stem baskets left after cutting. When the combine moves, the plants are brought to the shear elements 12 and the knives 6 cut the baskets. Then, by flexible slats and due to the counter-rotation of the knives 6, the baskets are guided through plane 14 to the conveyor 13. The stalks remaining after cutting the baskets are cut by the knives of the lower cutting unit. 5 il.

Description

a cutting machine for cutting stem-35 directional plant to the upper cutting

lei. The lower cutting apparatus is made of the upper 15 and lower rows of knives, with a row of 15 shifted back relative to the row 16.

Under the lower cutting unit, the bottom 17 is installed, connected to the conveyor 13. A transverse auger 18 is installed above the bottom cutting unit above the bottom 17 to remove the stems. Under the middle, the poppier and conveyors for separate removal of baskets and stems, characterized in that, in order to reduce the loss of grain and stems, on the non-working side of the knives of the upper cutting unit, flexible planks are installed perpendicular to their plane of rotation, and an angle of 90 ° between its edge and the straight line connecting the center of the front relative to the direction

the river auger 18 on the bottom 17 is made -5 movement of the combine side of the conveyor

an unloading window 19. The drive of the upper 15 and lower 16 rows of knives and the screw 18 is carried out from a combine engine (not shown).

The adaptation to the grain harvesting unit for removal of baskets and the middle of this edge, while the upper cutting apparatus is made of left and right relative to the longitudinal axis of the combine parts, and the knives of the left part are installed with

for sunflower harvesting 50 counter-rotation with respect to the knives

in the following way.

At the start of operation, by means of the hydraulic motors 8 and 9, the shafts 5 with knives 6 of the upper cutting apparatus are driven into rotation. The engine of the combine is driven in the right part, and the lower cutting apparatus is made in the form of rows of knives arranged one above the other, with the upper row of knives being shifted back along the stroke of the combine relative to the lower row of knives.

apparatus and conveyors for separate removal of baskets and stems, characterized in that, in order to reduce - the loss of grain and stalks, on the non-working side of the knives of the upper cutting unit perpendicular to the plane of their rotation, flexible strips are installed, and each countering element is installed to form a 90 ° angle between its edge and the straight line connecting the center of the front relative to the direction

conveyor side combine movements

for removal of baskets and the middle of this edge, while the upper cutting apparatus is made of left and right relative to the longitudinal axis of the combine parts, and the knives of the left part are installed with the possibility

the right parts, and the lower cutting apparatus are made in the form of rows of knives arranged one above the other, with the upper row of knives being shifted backwards along the movement of the combine relative to the lower row of knives.
