SU40080A1 - Sunflower harvesting machine - Google Patents

Description

The invention relates to cleaning machines / sunshafts with a rotating drum, equipped with gripping and automatically, at the time of seizure, shear devices. In the proposed machine, the devices that cut off the heads are scissors fixed with recesses in the recesses of the shaped slats and with scuffing on the curved legs, which end with the hinged cheeks fitted with a spring, try to keep the scissors in the open position. The contractions are folded so that they move towards each other at an angle, first moving from the stop of the cheeks to the head of the sunflower, and then from pulling the stem of the sunflower. Under the scissors in the notch of the blade, there are installed catching devices consisting of one or two triangles on the spring legs, which serve to trap the stem of the sunflower and hold it until the head is cut.

In the schematic drawing of FIG. 1 shows a side view of the header of the proposed machine; FIG. 2-view drum reel (reel); FIG. 3 and 3 view in two projections of scissors, cutting off sunflower heads; FIG. 4 is a side view of the scissors during the cut; FIG. five

(448)

And there is a 6-top view of the catching device in two versions.

The proposed sunflower harvesting machine is mainly a conventional grain harvester, in which part of the working bodies is replaced with special sunflower harvesting equipment.

The machine cleans the sunflower according to the double cut principle, which means that first shafts that are automatically fed into the threshing bar are banned, and then the stems that fall to the ground below the combine in front of the cutting unit are cut, a sunflower stalk cutting machine is a common grain combine machine, and the device cutting the sunflower is placed specifically in place of the combine reel and is a drum (reel) 1 rotating in the opposite direction In normal rotation, the reel in the combines, i.e., so that the stalks of the sunflower do not lean towards the cutting apparatus 12, but are pushed forward from it by the movement of the machine.

The reel 1 is equipped instead of the usual slats shaped slats 2

3. The form of the machine according to paragraphs. 1 and 2, characterized in that the trap consists of one triangle 19 with a spring leg 20.

4. The form of the machine according to paragraphs. 1, 3, characterized in that the reel blades are set tangentially.
