Description

The subject of the invention is a harvester for harvesting beets and similar root crops, capable of undermining root crops, extracting roots from the soil for the tops, leveling the roots and trimming the tops, dividing the roots and the tops into two streams, cleaning the roots from the ground and laying in the field of trimmed roots separately from the tops.

FIG. 1 shows a schematic side view of a combine; in fig. 2-part of spike-toothed tape; in fig. 3 is a plan view of a leveling roots conveyor; in fig. 4 is a partial view of the three conveyors in section along the line LL in FIG. one.

The main working units of the beet combine are: guides of tops-lifters 1, a belt-lifting machine 2 with a copying wheel, a digging leg 4, a root leveling conveyor 5, a clamping conveyor 6, a knife 7, a separator beater 8, an elevator for roots and tops 9.

When the combine is moving, the tops are guided by lifters / into the topping conveyor 2, consisting of two inclined endless belts stretched over the shchiki and rollers. The topping tapes on the inner sides have guide pins 10 interacting with the grooves of the guide rollers to ensure the stable operation of the tapes.

The plant, which is guided into a lifting platform, is clamped between the belts, and at the same time the root of the beets is digging down with the paw 4.

The root of the beets, half digged and grabbed by the tops, are removed from the soil with topping tapes and the beets are directed upwards to the leveling conveyor 5 and the clamping conveyor 6.

The conveyor belt 5, located at a certain angle to the top-lifting conveyor, is made of two chains.

having protruding strips 11, which form a movable lattice.

The clamping conveyor 6 installed under the leveling consists of two chains. A wavy elastic tape is attached to each chain along the outer contour. The leading branches of the chains with the help of the rollers and the springs are pressed against each other, while the belts of the chains mate with each other along a wave-like contour.

The hanging beading tapes are caught by the straps of the chains of the leveling conveyor for the bottom part of the tops. At the same time, the beet root is captured by the leading branches of the clamping conveyor. Thus, in a certain area of movement, the beets are clamped simultaneously by three paired conveyors arranged U-shaped among themselves: for the upper part of the tops-tapes of the topping conveyor 2, for the lower part of the tops of the conveyor 5 and for the root-clamping conveyor 6. With further movement of the beets puffing up the root from the top of the tops, while simultaneously pressing it from the bottom with the clamping conveyor. The cut of the tops from the top of the head is made in a plane perpendicular to the root axis.

The trimmed root is transferred by the clamping conveyor to the first section of the transverse elevator 9, and the tops lifted by two rotating rollers 12 mounted above the root leveling conveyor are discarded by the beater 8 to the second section of the elevator 9. From the elevator, the roots and tops go to the guide sleeves. By corresponding turns of the guide sleeves, the roots of the beet and tops are placed in several rows in separate rolls. The guide sleeve for tops can be replaced by a hopper.

The beet roots are cleared from the ground by a clamping conveyor and an elevator during the beet movement.

Claims (3)

1. Combine for harvesting beets and similar root crops, equipped with three paired conveyors for pulling beets behind tops, leveling and clamping the roots while transporting them to the knife with a device for separate stacking of roots and tops, characterized in that for stable clamping of root crops, regardless their sizes, and leveling the roots before feeding them to the knife, three paired conveyors are arranged U-shaped with each other, of which the topping conveyor is equipped with tapes with pincers interacting with grooves in the direction of rollers, a chain conveyor equipped with roots leveling strips, set in spaces between conductive strips steam circuit, and a clamping conveyor is in the form of elastic tapes, mounted on chains waves so that a bulge of one belt included in the cavity other paired tape 2. A combine according to claim 1, characterized in that its device for stacking tops tops separately from root crops is made in the form of paired rollers mounted above the root-leveling conveyor, in order to grab the cut tops and transport it, the beater, located behind the same a conveyor and intended to separate the tops of the root crops and the elevator with two longitudinal sections jM and. 3. In the elevator of claim 2, for the purpose of laying down root crops or tops of several rows in one roll, a terminal sleeve sleeve is used.
