Description

The invention relates to a beet harvester with a movable wheel, equipped with grippers for pulling out beets and with beet cutting machines, made in the form of ticks.

In the proposed machine, the knives mounted on a rotating wheel are equipped with broken, hinged levers, the ends of which roll along guide rails on the wheel.

In the schematic drawing of FIG. Fig. 1 shows a view of the (wheel shown on the side of Fig. 2, top view of the machine; Fig. 3, the side view of the machine; and Fig. 4-9, of the machine.

The proposed beet harvesting card consists of a pulling apparatus made in the form of a wheel 3 with two pairs of concentric rims, 2 and / 2. The rings of the inner rim 2, 2 are interconnected by a special connecting part, the middle part 4 of which is toothed., Outer rings rims /, / are provided with holes in which the lower ends of the one-horned forks-ticks 5 are passed, the tin of which rotates on the axis 7 attached to the rim 2, 2.

The ends 5 of the pincers 5, bending around the inner rim of the rim, are directed to the wheel axis.

These ends are equipped with ball bearings that move along rails W (Figs. 1, 2, 4, 5), which have a winding path, due to which the ticks are squeezed and opened at the right moment, i.e. in the moments of seizure of beets and its release.

Removed from the soil, the beets are exposed to the brush 72 (Fig. 1), which cleans it from the ground and fine roots. The root of the beets is pulled out of the clamps with the 5/5 piece, and the beets fall out into the bucket of the elevator 14. Broken levers 75 hinged at point 16 are located, the ends 9 of which are directed to the wheel axis carry the rollers included in the guide 7 7 on wheel 3.

The other end of the lever 75 is provided with a probe 78 1l to the same end of the lever attached, using spring holder J9, knife 2. The latter is equipped with a cutting 32 and consists of a steel plate, the front end of which is bifurcated, with the blade of one half covering the blade 22 with the other. The stalk 32 of the knife 20 is mounted in the holes 33 of the holder J9 so that the knife can rotate around the longitudinal axis depending on the height of the stylus, adapted

to the curvature of the beet crown. Roller-screw 24 is rotated by means of gear 23 and teeth 4 and serves to lift the beet leaves, which are then fed by elevator 27 to hopper 30.

The machine consists of three working sections, inserted into a common frame, having four wheels and an automobile engine,

The subject matter of the invention.

1. Beet-harvesting machine with a movable wheel, equipped with grippers for pulling out beets and with pruning

beetroot crowns with apparatuses made in the form of mites, characterized in that the knives 20 are mounted on a rotating wheel 3 and are equipped with broken hingedly reinforced levers 75, the ends 9 of which roll along guide rails 77 on the wheel 3.

2. The shape of the beet harvesting machine according to W 1, / is characterized in that, in order to obtain a tapered cut of the cutting head, 32 knives 20 are mounted in holes JJ of holder 19 pivotally about its longitudinal axis.
