Description

Single beet harvesters containing lifters, haulm cutting apparatus, elevator for picking cut tops, horizontally - a transverse conveyor for receiving the tops from the vertical elevator and transporting it to the bunker, diggers with rotary drums, longitudinal root conveyor, root bunker and the mechanism of the lifting of the working bodies, is known.

The peculiarity of the proposed combine is that, in order to better clean the beet roots from the ground, the longitudinal root conveyor is equipped with articulated keys. The bottom of the hopper-conveyor belt is a moving barbed chain web stretched between two (leading and driven) rollers, the left part of the conveyor belt together with the driven roller can be lifted upwards, forming with the side looms a bunker for aggregating beet roots. When lowering the blade into a horizontal position, it forms a moving conveyor belt that takes out the beet roots and places

them in the form of heaps on the left side of the combine.

FIG. 1 shows a general view of a single-side harvesting combine with devices according to the invention incorporated therein; on . 2-view of the combine in the plan; on fng. A 3-unit harvester containing diggers, rotary drums and longitudinal and transverse root conveyors CBeiuibi.

The pivotally suspended keys / are located above the web of the longitudinal conveyor 2. The other conveyor, hopper 3, is a bar chain tensioned between two rollers.

All mechanisms of the combine are mounted on a flat frame resting on a four-wheel pneumatic drive, with a car-like front end.

The combine operates on a tractor with power takeoff for driving its machinery into operation.

The process of harvesting beets proceeds in the following sequence.

When the combine moves, the combiner steers the beet combiner through the beet rows, with the middle row of beets going between lifters 4.

Lifters 4, spanning a variety of beets on both sides, straighten the tops and, in this state, when the machine moves forward, transmit it to the grooves 5 of the cutting unit, which regulate the cutting height of the root head; the head is cut by a flat knife 6.

The cut-off tops of the tops are picked up from the ground using a finger-mounted vertical elevator 7 of the tops, rotating from the ground, transported upwards and transferred to the horizontal-lateral conveyor 8 of the tops, which will transport the tops to a 0.3 and /. From the bunker, the combiner throws the tops on the cleaned side of the floor in the form of small heaps.

After pruning the tops, the pruned roots digging takes place, which is carried out by two paws of kopaci 9 of the lemesh type.

Paws digging dive into the ground to a depth of 90-100 mm and with the forward movement of the machine squeeze the beet roots up. The crusts squeezed out of the ground fall between rotating rotary, tactile drums 10, where they are partially cleaned from the ground and transferred to a longitudinal conveyor of 2 beet roots.

On the longitudinal conveyor, the roots are additionally cleaned from the ground with the / keys and transported upwards, from where they enter the conveyor-bunker 3. In the conveyor-bunker there is an accumulation

beet roots weighing up to 50 kg and their final cleaning from the ground. From the conveyor-bunker the combiner unloads the beets in the form of small heaps on the harvested side of the floor. This ends the mechanical process of harvesting the beets by machine.

Subject invention

Single-beet beet harvester consisting of lifters, haulm cutting apparatus, elevator for picking cut tops, horizontal transverse conveyor for receiving the foliage from the vertical elevator and transporting the latter to the bunker, rotting drum copers, longitudinal root transporter, root bunker and mechanisms raising the working bodies, characterized in that, in order to clean the beet roots from the ground, the longitudinal root transporter is provided with keys hinged above it, and the bottom of the bunker for the roots beetroot serves as a moving bar chain web stretched between the two leading and driven rollers, the left part of the conveyor belt together with the driven roller can be lifted up with the lever upwards, forming with the side walls a bunker to accumulate the beet roots, and when lowering it the horizontal position of the moving conveyor belt takes out the beet roots and lays them in the form of heaps on the left side of the combine.
