Description

It is known to use trellised drums for root cleaning, as well as cleaning loaders.

A distinctive feature of the proposed combine is characterized by the use and cumulative use of a belt conveyor with a rotary divider, a beater with el | Sticelami and a scraper elevator of the roots with a cleansing drum.

In the SKEM-3 and SKP-2 combines there are no reliable mechanisms for cleaning the roots from the ground and tops, as well as for cleaning the tops from the ground. Therefore, the beet roots have to be unloaded from the bunker of the beet harvester into the field, for further bulkheads and manual refining, with the aim of bringing them to the existing receiving conditions, which requires 10-12 or more man-days per 1 ha. In addition, the beets unloaded by the SKEM-3 and SKP-2 combines for a long time are in the field in small piles, which leads to a decrease in the roots and a decrease in their raw qualities. These disadvantages are eliminated by the introduction of the continuous-transshipment method for harvesting with combine harvesters equipped with cleaning devices. FIG. 1 and 2 shows a harvester at the side and in the plan.

Mounted under the cutting unit of the combine, the receiving tape root conveyor / is an endless belt of rubberized fabric or other material. The roots trapped on this conveyor are fed to a rotary divider 2, made in the form of a grid vane, which is driven by a pair of bevel gears. The roots are transported from the conveyor to the divider and last to the bit 3 and then to the screw cleaner 4.

The beater 3 is a drum equipped with elastic bilami that partially beat the tops and ground from the roots and help the divider to feed the roots to the auger cleaner 4.

The latter is mounted at the rear of the main frame of the combine and is intended for additional cleaning of the roots from the ground and tops. Screw cleaner consists of four forcibly rotating

cylinder augers arranged parallel to the receiving root conveyor. The two middle augers rotate towards each other and form a working pair, and the two extreme ones are vras; they are correspondingly middle in the same directions and form an auxiliary pair for cleaning the working pair from adhering earth and tops to high soil moisture. The transfer of the vrach from the cardan drive 5 to the auger cleaner is dried through the chain gear 6, the side shaft 7 and the Scherten® system, enclosed in a common box.

The scraper elevator 8 of the roots consists of two endless stub-roller chains interconnected by bar scrapers. The scrapers of the working branch of the elevator slide along the guides and, with their protrusions, clear the space between the guides from sticking dirt. In the lower part, the grain of the elevator rests on a cleaning drum, where the beets fall from the auger cleaner and are additionally cleaned. In the upper leading part there is a hatch through which the beet roots fall onto the discharge conveyor of 9 roots.

Instead of the small-sized topper and topper, existing on the SKEM-3 combine, the proposed elevator-cleaner 10 tops of the tops and the trailed bunker 11 of greater capacity were supplied on the proposed combine. The cleaner elevator is hinged on brackets to the moving and main frames and in the working position is at a certain angle to the horizon. Elevator-ochI | Statel sifts the ground and transports the tops to the trailed bunker.

The topper bunker 11 is attached to the main frame at the back of the machine and consists of a welded frame 12 mounted on two pneumatic wheels 13, a swiveling rod bottom 14, a hinged-back wall 15, and an automatic closing machine.

The combine works as follows. A plant collected in a bundle of tops lifters 16 is sent to the open paws of the topping sections J7 for clamping. At the same time, the undermining paws 18 break the connection of the roots with the soil and lift them upwards. The roots, excavated and clamped behind the tops, are removed from the ground, brought to leveling devices 19, leveled in height, and fed to cutting disc knives 20 which cut the tops. The cut tops of the tops are dropped by the tips 5 to the elevator cleaner 10 of the tops, and the cut roots fall onto the receiving rubber conveyor / roots and are fed to the screw cleaner 4 by a rotary divider 2 and the beater 3. The cleaned and separated roots fall into the cleaning drum 21 of the scraper elevator 8 of the roots. The roots with uncircumcised tops are tightened with a working pair of augers and are fed to the cutting apparatus 22 of the auger cleaner, where the roots are cut and also fall into the cleaning drum of the scraper elevator of the roots. In the drum and on the scraper elevator, the remaining ones are separated from the roots and then they are fed to the unloading elevator 9, which directs them to the transporting means 23. The cut tops of the tops are cleaned off the ground from the elevator and fed to the hopper / tops, which, as it is filled unloaded.
