(54) COMBINE FOR CLEANING LARGE-STYLE FRESH CROPS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for harvesting large-strand bast crops.

According to the main author. St. No. 803892 is known for a combine for harvesting large-stemmed cultivars, including a driving apparatus installed on a lead, and their driven sprockets, a chain-finger conveyor with a guard, a clamping conveyor, forming a stream, feed rollers and decorticator, and a finger-chain and clamping conveyors are installed parallel to the feed rollers, the end of the clamping conveyor is placed under the beginning of the clamping zone of the feed rollers 1.

The disadvantage of this combine is the loss of bast when winding in the lead-in part of the mobile drums. Winding affects the stability of the combine's process. Winding occurs as a result of the fact that the small parts of the stems (usually thin), when lifted by the clamping conveyor to the mobile drum after cutting, are below the butts of the main mass of the stems. Hovering in the lower zone

bearing support, delayed. The apical part of the restrained stems lays down along the bilny drum, entangles the newly arriving stems and carries them into the zone of the lower support bearing, winding occurs. As a result of the windings, a valuable product is lost, the process is disturbed, since with significant windings from the blues on the metal parts, as they rotate, the bast may ignite. Elimination of windings causes great downtime of the combine and large labor costs.

The purpose of the invention is to increase the reliability of the combine and reduce bast losses.

The goal is achieved by the fact that in the lead-in part of the mobile drum there is a groove, in which the knife mounted on the frame passes, forming scissors with the ends of the mobile drum.

FIG. 1 shows a combine for harvesting large-stem-bearing bast crops, side view; in fig. 2 is a view A of FIG. one.

The harvester for harvesting coarse-grained bast cultures consists of a cutting apparatus 1 installed under the lead-in part of the chain-finger conveyor 2 and the clamping conveyor 3 installed parallel to the conveyors 2 and 3 of the feed rollers 4, under which the bilder drums 5 are located. rollers 4 installed lamellar bars 6. In the lead-in portion of the drum-5 drum there is a Groove, in which the knife 7 mounted on the frame passes, forming 5 shears with the ends of the bench drum 5.

The device works as follows.

The stems cut by the cutting device 1, captured by the clamping 3 and the chain-finger conveyor 2, are transported to the feed rollers 4, which feed the stems into the area of the action of the drum 5. The small parts of the stems are usually lower (mostly thin) as for example the stem 8, fall into the zone of the knife 7. The long butt of the stem 8 falls between the rotating beels and the knife, cut off, and the stem undergoes further processing together with other stems. The bulk of the stems with a valid

The crushing of the feed rollers 4 enters the action zone of the reel drum before the knife and is therefore processed without cutting off the butt part.

The reduction in the loss of the received bast occurs due to the elimination of the windings in the lead-in part of the bilder drum, which in turn has a positive effect on the reliability of the combine, as it requires the elimination of the winding requires significant downtime of the combine and greater labor intensity.
