Description

The subject of the invention is a self-propelled continuous combine for harvesting double-cut sunflower nods and feeding them to the blades by means of paired endless conveyors arranged one above the other by pa separators.

FIG. 1 shows a diagram of a combine for harvesting sunflower, side view; in fig. 2-combine, top view; in fig. 3-node trimming and picking baskets; in fig. 4-node pruning and see tees.

The combine consists of a header and a threshing device. The header includes lifters /, an upper needle conveyor 2 for grasping stems, a conveyor 3 for clamping gum equipped with circular blades, internal conveyors 4 and .5, a transiorter 6 for removing stems, circular knives 7 for cutting the stems inside / machine, circular knives 8 for basket shears and lifters .9 for removing baskets from a needle transnorter.

The thresher of the described device does not “differ from the usual combine thresher adapted for harvesting sunflower.

The upper needle conveyor 2, intended for the h: stalk grab, is a paired chain located in a plane inclined to the horizon at an angle of 45 °. The chain link of the upper conveyor is provided with radial fingers 10 with a pitch, which are relatively free for the position of the stems between the fingers along the whole way of their transportation to the cutterbar.

In addition, the chain link of the upper conveyor. They are equipped with vertical needles, which are punctured with the rear part of the basket when they are cut, and are fed to a cutting-detachable apparatus.

On the rollers of the sprockets of the upper conveyor 2, rotating disk knives 8 are installed to separate the baskets from the stalks. At the end of the shed of the valuable branches, spiral steel .NO 74952 is installed

py lifters 9 for removal from the needles of the basket conveyor and individual stubble leaves and weeds. Instead of lifters, special beaters can be installed.

The lower transnorter 3 is a paired, worn sprocket, s plane inclined to the horizon at an angle of 15. The forward sprocket of the conveyor is developed into special corrugated rollers 12 of the same diameter: meter with asterisks. The two rollers, rotating inward, form a constant entrance target between them; The path through it, the stems are crushed to a certain set} of the first size.

Getting between the loose branches of the lower conveyor, the ends of the smoth stalks are equally trapped all along the bottom of the transport to the blade unit.

From below to the ends of the rollers 12, sawtooth overlapping discs 13 have been fixed, which, simultaneously with the removal of the stems by the rollers, cut them. Cutting the stems at the moment of their smothing with rollers can be replaced by punching the stems with sieciali paws, then the lower transnorter will work as a pulling and cutting unit. At the time of cutting the stems into parts, the root part of them will separate from the main stem and can be removed from the ground.

Aligning the stalks to the baskets is achieved by having an angle between the upper needle and lower conveyor, the free position of the stalks in the upper and middle conveyors, pinching of the ends of the stalks in the lower conveyor and the speed mode of the conveyor; : i header.

The secondary auxiliary conveyors 4 and 5 are single-link chains worn on sprockets located on the same shafts with sprockets on the lower conveyors. Medium conveyors are designed to consistently receive shorter stems and eliminate the effect of large lengths of stems when leveling and feeding them to the stem cutting machine and the conveyor 6 for stem removal.

The inner stem cutting apparatus is circular knives 7 mounted in three rusas on shafts of sprockets of lower and middle conveyors.

Claims (2)

1. Ca 1-way nr coil harvester for harvesting sunflower with double cut stalks and feeding them to the cutter blades by means of paired endless chain conveyors placed one above the other on the other, characterized in that, in order to keep the torn sunflower baskets, the upper conveyor is equipped with needles located normally to the movement of the chain and interacting in the upper part of the conveyor with spiral pullers, removing the sunflower baskets from the conveyor. 2. In the combine according to claim 1, in order to simultaneously cut the stems into several parts, several transporters of different lengths arranged one above the other and parallel to each other, equipped with relative devices and installed at an angle to the upper conveyor, are used. -.feis  .-, v-r -; -: i; ., -txC --4 ::; --- - :: - r-f Ui ., - f; -;: .---,;:  S v - ,:, lg lpg -T- t-- l% &m; F “// 1  ViV-t ::.  r7 -m
