Description

The invention relates to beet harvesting machines equipped with conveyors for transporting beets and cut tops. In the proposed machine, a conical drum equipped with spring teeth and a closed row c is used for removing the beets from the ground and feeding it under the knife for cutting the head. digging tool.

In the schematic drawing of FIG. 1 shows a view of the beet harvester from the side; FIG. the same from above. :

On the frame, resting on the crankshaft on the front and on the straight axle on the rear, two pillars are fastened close to the front end. On the left, if viewed from the direction of travel, the rack 7 is reinforced in a vertical position by a digging tool / in the form of a cutting knife, directed by the blade forward and passing into the paw in the lower part for cutting the beets from below. In the back of the knife this goes into a curved lattice-shaped wall, like a blade in a circle. In the right pillar, a drum 2 rotating on a vertical axis is fixed, arranged to resemble a bevel gear tapering downwards. The teeth are made very dull so that the beetroot roots cannot be injured, and, in addition, springy. Step

between the teeth is approximately equal to the diameter of the smallest roots. Springing teeth are made so that, if roots of a larger diameter fall between them, they can diverge and contain these roots between them. The curved strips of the grating wall, as they move away from the cuttings of the knife, are slightly raised upwards. At the upper edge of the upper strip, the bead is embedded, crossing as it approaches the end of knife 6.

The described device performs two basic operations: cutting the roots out of the ground and cutting the tops with the crown, for which the knife blade goes in the ground very close to the row of beet roots on the left side and, breaking them with the soil, paws the roots from below, and on the right side, the coupling with the soil has already been disturbed by the plow passed in front. Thus, when moving this device forward, a narrow strip of earth, along with the beet roots, cut from all sides, but staying in a standing position, falls through the drum and the grating wall of the knife. A part of the earth immediately falls down, a part through the lattice wall to the side, and the crunch of beets inevitably falls into a hundred position

in one of the sockets between the two adjacent teeth of the drum 2 and with it continues, rotation from front to back. Pressing / springing teeth of the drum to the curved wall of the knife and sliding along the strips of this wall going from the bottom up, root, beets | 1 is raised from bottom to top, like. on the thread. The upper part of the wall is provided with a side from the inside, the side, why, and the beet root rises upward until it is pressed against the head, and then continues to slide at the level of this side. At some distance from the end, the bead goes into knife 6, which, when it moves further, carried along by the drum, cuts off the head together with the tops:

Such a device fully guarantees both the removal of the roots from the ground and the cutting of all heads with tops, and the possibility of placing the knife at any level relative to the board decides

the task of pruning heads of the desired size. After pruning, the root and the head with tops fall separately onto conveyors J and are placed in separate boxes 4.5. Cleaning the roots from sticking earth also continues on the conveyor. Since both the rotation of the drum and the movement of the conveyor do not require much effort, both of them receive movement from the rear travel wheels of the mandina.

The subject matter of the invention.

A beet harvesting machine with conveyors for moving beets and cut tops, characterized in that, next to a digging tool 7, a drum 2 equipped with teeth and reinforced with a bevel gear is strengthened, which serves to remove the beets from the ground and feed it under the knife for cutting the head.
