Description

Beet-packing machines are known, for example, for over-wetted areas of beetroot, equipped with circular knives for trimming tops, haulm holders, a topping section, a digging foot, leveling and cutting devices, conveyors and bunkers.

The described beet harvester differs from the known ones in that the haulm conveyor is a pair of V-shaped belts with a grooved outer surface. The conveyor is driven by double-sheave pulleys simultaneously with the straps of the topping section, with which the conveyor forms a single stream, which directs the trimmed tops to the bunker. Such a device allows to obtain clean tops and more efficiently use the bunker capacity. In addition, for better cleaning of beet roots from impurities, a longitudinal root transporter-root cleaner from the soil and a transverse scraper elevator are used in the combine, forming a vertical adjustable slit cleaning the roots from leaves and other plant debris. The conveyor-cleaner is made in the form of a movable upper shaking branch of the web with a fixed rod web above it.

FIG. 1 shows a beet harvester, side view; in fig. 2 - the same, top view; in fig. 3 - topper conveyor and terebilny section; in fig. 4-transverse scraper elevator; ka fig. 5 - conveyor root cleaner.

The beet harvester includes the following main knots: circular knives / for cutting leaves that fall to the leaves, the leaflet 2, the digging leg 3, the topping section 4, the leveling machine 5, the cutting unit 6, the conveyor 7 tops, bun-ker 8

No. 148983- 2 tops, cross-scraper elevator 9, conveyor-cleaner 10, bunker with 11 roots. .

The corrugated V-belts 12 and 13 of the topping section 4 are driven by two-sheave pulleys 14 and 15, which simultaneously result;; movement and grooved belts 16 and 17 of the conveyor 7 tops. A trinsnorter haulm forms a stream, which is the continuation of a topping section stream. The inner parts of the belts 16 and 17 are pressed against each other by the pressure rollers 18, and the tension of the belts is provided by the tension rollers 19. Under the carrying upper branch of the conveyor-cleaner 10, elliptical sprockets 20 are mounted, which shake the upper web. Above the canvas is a rod cleaner 21 made of two chains interconnected by rods.

The plant collected in the bundle by the lifter 2 is sent to the lifting part 4. At the same time, the paw 3 breaks the connection of the roots with the soil and lifts them up. The roots, excavated and clamped by the topping section, are extracted from the ground, brought to the leveling device, leveled in height, and fed to the disc blades of the cutting unit, which cut the tops. The cut tops of the tops are captured by the conveyor 7 and retracted into the bunker 8. The cut roots fall on the transverse scraper elevator 9. Having a different trajectory of movement, the roots "fly over the slot and fall on the conveyor cleaner 10, and the tops and crop residues fall off into the slot. On the conveyor-cleaner, the roots are retained by the rods, which leads to their accumulation and repeated agitating with the shaken cloth; this removes the ground from the roots, breaks up the clods and sifts through the conveyor belt. Purified roots fall into the bunker 11.

Subject invention

.. 1. Beet harvester, for example, for wet areas of beetroot, including circular knives for trimming the leafy leaves of the haulm, tops tops, dragging, digging paw, leveling and cutting apparatus, conveyors and hoppers of the tops and roots, in that the purpose of obtaining clean tops and more efficient use of the capacity of the bunker, the conveyor of the tops of it is made of a pair of V-belts with a grooved outer surface, driven by two-fold pulleys simultaneously with the belts A separate section forms a single stream that guides the cut tops at an angle to the axis of the combine into the bunker.

2. A combine harvester according to claim 1, characterized in that, in order to better clean the beet roots from impurities, it collectively applied a longitudinal root-belt transporter, made in the form of a movable upper agitated branch of the web with a fixed rod web above it , and. The transverse scraper elevator, forming with the cleaner a vertical adjustable slot for cleaning the roots from leaves and other plant residues.
