Description

Known combine harvesters for cleaning kenaf on green bast, consisting of a mowing-type cutting apparatus and drum-decorticators, do not allow bast to be obtained in a single pass of the combine.

In the proposed combine, in contrast to the known, in order to obtain bast in a single pass of the combine, the following are jointly applied: the cutting unit of the mowing machine, gripping finger conveyors, feeding conveyor belts; leptoch o-roller clamping conveyor; a double drum decorticator for processing the tops of the stems and a clamping conveyor with a double drum decorticator for processing the butt portion of the stems.

FIG. 1 shows the proposed combine, side view; in fig. The same, top view.

The proposed combine is a trailed machine with a drive of working bodies from the tractor's power take-off shaft. It is designed for harvesting and processing freshly cut stalks of kenaf on bast in one pass. The combine consists of harvesting and lubriding parts mounted on a common frame equipped with transorting wheels.

The harvesting part of the combine consists of a cutting unit / mowing machine of the type, gripping finger conveyors 2, feeding belt conveyors 3 and a plate-cleaning drum 4. The lobe part of the combine consists of an apical cutting unit, intercepting mechanism and butt and I went to the whiteboard.

The apical pivotal apparatus and the processing of the tops of the stems. Oi consists of a table 5, three belt-roller conveyors 6 and a two-drum decorticator 7 with a deck.

The butt cutting machine consists of a clamping conveyor 8 and a two-drum decorticator 9.

No. 142099 - 2 -.i

The operation of the combine is as follows.

Finger conveyors seize one row of stems (two lines) at a height of 1 m. At the same time, cutting of captured stems-height, 4-9 cm from the soil surface, occurs. The cutting height is adjusted by the setting of the base (height).

The grabbed and cut stalks in an upright position are transported by dB; 5 belt conveyors and conveyors to a plate-cleaning drum, which, rotating in the direction of the movement of the stalks, knocks the leaves and grass with their fingers.

Upon further transportation, the peeled stems rest on the feeding table, bend and fall onto the belt-roller conveyors 6. The stems are fed by belt-roller conveyors in a horizontal position to the decorticator 7, which produces the branch separation of the upper part of the plants. When this occurs, the stalks are wringing with the preliminary flattening of the place of break and the processing of the upper part of the stems.

After processing the top part, the stems are intercepted by the intercepting mechanism via a clamping conveyor 8 of the commander. In the butt apparatus using the decorticator 9, the butt part is processed. After processing the stems over the entire length of the scutching machine 10, the bast received by the conveyor is dumped into the bunker.

Thus, in one pass of the combine, ready bast is obtained, which significantly reduces costs and speeds up the harvesting process.

A harvester for harvesting kenaf for green bast has been manufactured, tested, approved by the All-Union Scientific Research Institute of Agricultural Mashinostroeniya (VISHOM) and recommended for introduction into agricultural production.

Subject invention

A combine for cleaning kenaf on the green bast, consisting of a cutting unit of the mowing type and drums-decorticators, from the fact that, in order to obtain bast in one pass of the combine,; finger conveyors feeding conveyor belts; belt-roller clamping conveyor; a double-drum decorticator for processing the tops of the stems and a clamping conveyor with a double-drum decorticator for processing the butt portion of the stems.
