Abstract

The invention relates to agriculture, namely to machines for harvesting tall stem bast crops, such as kenaf. The aim of the invention is to improve the quality of the bast and increase the productivity of the machine by reducing the coagulation and entanglement of the stems. A combine harvester for harvesting tall-stemmed bast crops contains wound 1, under which a cutting apparatus is mounted in front of it

2, on top of which a clamping conveyor 3 is located. Behind the cutting unit there is a grass separating drum 4 and an inclined plate 5 mounted on the front part of the feeding table 6, in the slots of which there are transverse chain-finger conveyors 7 for feeding the stems 8 to the plastic and supporting rollers, adjacent to which is a single drum decorticator and a remote conveyor. During operation of the combine from the clamping conveyor 3, the stalks 8 at the time of laying on the feeding table 6 interact with the front part of the feed plate 5, which is set at an angle of 40.. .so, and begin to move. The invention relates to agriculture, namely to machines for harvesting high-stemmed bast crops, such as kenaf.

The purpose of the invention is to improve the quality of bast and increase machine productivity by reducing the laxity and entanglement of the stems.

The harvester for harvesting tall-stemmed pebble crops contains frame 1, under which B of the front part there is a cutting device 2, above which a clamping conveyor 3 is located. Behind the cutting device there is a grass separator 4 and an inclined plate 5 mounted on the front of the feeding table 6, in grooves which are placed transverse chain-finger conveyors 7 for feeding the stems 8 to flatting 9 and supporting 10

from down, overcoming the power of friction. As a result, the speed of movement of the butt-part of the stems along the surface of the inclined plate will be somewhat less than the speed of the feeding apical part. Due to this, simultaneous laying of the butt and top part of the stems on the feeding table is ensured. This ensures parallel stacking of the stems relative to each other and is oriented to transport them to the separating part of the combine. When the stems are moved along the inclined plate 5, they become obstructed, which leads to an improvement in the quality of the lumbar, excluding the possibility of finishing the butt part. 3 il.

Butt part of the stems is installed inclined plate 5 at an angle N to the surface of the table (figure 2).

The angle of-, providing non-stop sliding of the end part of the stems from the surface of the inclined gshastina, can be determined by the expression: oi arct h / a (fig. 3), where h and a are the installation coordinates of the inclined plate.

The best-quality work shows an inclined plate in conjunction with the front part of the stems with great

an angle of 40 ... 50.

In order to reduce the stalk breaking of the stems that are formed at the time of picking up and moving in the clamping conveyor, the size h is taken to be equal to the average value of chattering, which is 20 cm, then

size limit 16, V ... 24 cm.

The harvester is a trailer mounted to a tractor. Working bodies are activated

from the tractor's power take-off shaft (not yet shown).

clamping conveyor 3, transports and dumps them on the table 6 filing. When moving in the belt conveyor, the butt part of the cut stalks is found with a grass separator 4, which separates the weeds and underdeveloped stems (trim).

The stems laid on the supply table 6 continue to move in a continuous stream by chain-pin conveyors 7 and are received by the flattening 9 and supporting 10 rollers to be fed into the treatment area of the decortator 11. The bast received is taken out of the treatment area by the clamping belt conveyor 12 and is formed into a portion that is dropped onto the stubble portion by spreader 13 to dry.

The stalks, dropped from the clamping conveyor, 3 at the moment of laying on the supply table 6 interact with the surface of the inclined plate 5 and begin to move downward, overcoming the force of friction. As a result, the speed of movement of the computer part of the stems along the surface of the inclined plate will be slightly less than the speed of the freely falling apical part. This ensures the simultaneous laying of the butt and top of the stalk part on the feeding table. This ensures parallel stacking of the stems relative to each other and is oriented to transport them to the separation section of the combine. This prevents slaughtering in front of the feed rollers and improves the quality of lumbar release.

Due to the installation of an inclined plate at the place of reception of the combo part of the stems, which arrived with the steadiness of the stems, when moving along its

 the surfaces are plugged up, and, therefore, the magnitude of ripple is reduced to a minimum, which leads to an improvement in the quality of Luba Q divisions, excluding the possibility of under-processing the computer part. Moreover, the bunching (alignment of the butt part) of the stems will be carried out very effectively, since

5, the apical part of these stems is in a free state, thereby weakening the bond between them.
