SU148625A1 - Beet harvester harvester type - Google Patents

Description

Beet harvesters are known to have active or passive dividers, dropping legs, topping and leveling machines, hydraulic machines to guide working bodies in rows with copying wheels on a movable frame, conveyor-cleaners of tops and roots, haulters of roots and roots, elongated (fitted ) root elevator.

However, they do not completely clean the beets from the leaves and the ground.

In the proposed beet harvester, in the system of the conveyor-cleaner (between the horizontal conveyor and the grate adjacent to the inclined conveyor), a fender roller of reverse rotation is installed. At the same time, a screen made of chains is installed above the baffle roller of the horizontal conveyor. The drum, mounted on the driven shaft of a horizontal conveyor, has on its surface knives with an angle between the cheeks of up to 60 °, located between the rods of the conveyor.

In addition, the toothed disk of the leveling apparatus with teeth in the form of triangles with a limited thickness of workers

surfaces made double. Between the discs there passes a passive guide fork, terminating at the cutting edge of the disk knife.

Thanks to this design, good grounding of the beets from the tops and the ground is provided, as well as high-quality cut of the tops and prevents clogging of the tops and the ground.

FIG. 1 and 2 schematically shows the device of the proposed combine; in fig. 3 is a view along arrow A in FIG. one; in fig. 4 - device of conveyor-cleaners of the pile with the baffle roller; in fig. 5 - device leveling apparatus; in fig. 6 is a section along BB in FIG. five.

The proposed beet harvester is essentially a multi-purpose harvester and includes active or passive dividers 1, paws 2, top-3 and leveling devices 4, hydraulic automatic machine 5 for guiding the combine in rows, copy wheels on a moving frame, conveyor-cleaners 6 roots and tops, hoppers 7 and 5 (respectively) of roots and tops.

In the conveyor-cleaner 6 between the horizontal conveyor 9 (Fig. 4) and the grate // adjacent to the inclined conveyor 10, a bogie roller 12 of reverse rotation is installed, located below the axes of rotation of the conveyor shafts 13 and 14. Above the roller 12 is set the screen 15 of the chains. The drum 16, mounted on the driven shaft 14 of the horizontal conveyor 9, bears on its surface knives 17 with an angle between the cheeks of up to 60 ° C, located between the rods 18 of the conveyor.

The harvester has an elongated composite elevator for feeding roots to vehicles (FNG. 3), which ensures the use of the proposed combine for harvesting sugar beet in a continuous-transshipment way without the cost of manual labor for the additional cleaning of the roots.

The finger-toothed disk of the leveling device 4 is made double (Figs. 5 and 6), and between the disks 19 and 20 there passes a passive guide fork 21, ending at the cutting edge of the disk knife 22.

The work of the proposed combine differs from the work of combines of the brands SKEM-ZG, SKP-2 using new working bodies. For example, better cleaning of beets from tops and earth is carried out in two conveyors-cleaners 6. At the same time, the impurities in the heap of roots are drawn into the active gap formed between the roller 12 and the drum 16. The removal of impurities is additionally accomplished by the second baffle roller mounted on the elevator roots (not shown).

The grate 11 thus facilitates the cleaning of the roller 12 from the ground and eliminates the loss of roots. In addition, the presence of the screen 15 creates conditions for the best selection of impurities, and the knives 17 cut the tops from the roots and prevent the roller 12 from being poured with earth and weeds wrapping on it.

The plant is cut by a double palmate-toothed disk with a new form of intake teeth

(fingers). This provides a more stable fixation of the roots, better cutting of heads with tops at the roots with the least waste of sugar-bearing mass into the tops. In addition, the leveling discs are not clogged with earth in wet weather conditions.
