Description

: The invention relates to an elevator-type potato harvesting machine with a device for loosening a formation installed under an undermining tool and made in the form of a rotating drum with fingers. In the proposed potato harvester, gears rigidly connected to the fingers and rotatable by means of a planetary gear from the shaft of the drum are used to actuate the crushing of the loose star drum.

J; -l In FIG. 1 shows a side view of a potato harvester; FIG. 2 - the same top view. ;;, | In the proposed double-sided elevator-type machine, potatoes are equipped with plow bodies 5 with lattice dumps, moreover, in order to harvest two rows of potatoes to a common elevator, one of the buildings passes through the other, and the other is left-hand. Both housings are secured with racks 2 attached to the gr Yyl and 5 machine frames. In front of the hulls, along the line of the field board, circular knives b are attached to the same Tr DIL m 3, which are used to cut stems from the tops of the tops. Undercut layer with; potatoes

(169). gives under the action of a loose formation a device made in the form of a star-shaped drum with fingers / 7. Gears 23 are rigidly connected to the fingers and actuated by means of a planetary gear from the shaft of the drum 18 to actuate the drum fingers. The loosened layer flows onto an inclined elevator 27, the endless web of which is made of steel bars 38 forming a grid. The upper branch of the elevator web is driven by a star-shaped elliptical disk 44, thereby sifting the earth through the grating web of the elevator onto the ground, and the potato tubers and tops are dumped from the end of the elevator to the second elevator through a device separating the tops from the tubers. This device is located under the longitudinal grille 61 and consists of an endless chain 5 with teeth 60 arranged in a checkerboard pattern.

The distance between the teeth is determined on the basis of the passage between the teeth of the maximum tuber. When tubers and tops fall from the first

the elevator, the teeth 60 pick up the tops and unzuts her Nazazak machine, dropping it to the ground, and the tubers fall through

 , -Htf - -. The trellis and enter the lower elevator 63. The lower elevator is trellised and is also commenced to be motions by stellar elliptical discs 68. The earth is finally sifted through the elevator, and the tubers are transported to the appropriate assembly.

All working bodies are mounted on a 4-wheel trolley, with two front wheels mounted rotatably on semi-axles with vertical pillars that are connected to a 75/7 trailer. The movement of all working bodies receive from the tractor universal shaft 76 through the transmission box 79.

The raising and lowering of the bodies is carried out by the steering wheel JJ6, carrying a screw screw at its end // 7 coupled to the sector JJ8. The latter is mounted on a square shaft connected in grids / 25 with piles 5. | The worker, acting on the flywheel 727, can change the depth of the bodies, as well as raise them in a transport area.
