Description

one

The invention relates to agricultural machines, in particular to machines for harvesting cabbage.

Cabbage harvesting devices are known, comprising guides and a disk knife with a vertical axis of rotation.

However, when harvesting the heads of cabbage with such a device, damage to heads of cabbages may occur, both when they are removed from the soil and when moved to a disk knife.

The purpose of the invention is to move the heads of cabbage to a disk knife without damage.

This is achieved by installing a beater with curved blades covered with an elastic material over the guides in front of the disk knife.

FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view.

The device consists of guides 1, a dropping paw 2 mounted above the guides of the finger beater 3 with elastic strips 4 rotating above the guides, a segment-disk knife 5 and a conveyor 6. The knife is provided with cutting segments 7, and the counter-part 8 is fixed on the device frame .

The ends of the guides 1 are gently bent upwards and move directly along the floor surface. As undermining paw 2, for example, can be applied.

flat cutting paw razor. The beater 3 is provided with curvilinear fingers covered with an elastic material and planks 4 of an elastic material, which are installed with a backward slope relative to the direction of their movement. The shape of the fingers is chosen such that at any point of intersection of the finger with the axial line between the guides, the angle between the axial line and the tangent to the finger is

equal to 90 °. In this case, the fingers will not push the cabbies to the side.

The beater is set so that its fingers move over the guides with a small gap, and the paw digs up the stump after the beater's finger grasps it. The rotational speed of the knife is selected depending on the distance of the heads in a row so that there is only one stump per segment. Transporter made

from elastic material, so that the heads that fall on its surface after cutting are not damaged.

When the device moves, cabbages with stumps fall into the gap between the guides 1. The fingers of the beater 3 pick up the heads of the cabbage from the bottom, and the slats 4 support it from falling out. The paw 2 then digs up the head of the head of the head in the soil, and the head is directed by the guides 1 and the beater 3 is removed from

soil and is sent to the cutting disk 5. At the moment of approaching the disk 5, the stalk separates from the head with segment 7, counter part 8. Beater 3, supporting the head with bar 4, after cutting the stalk drops it onto the conveyor 6, which is mixed, head out into collection or vehicle. During the entire time of contact of the parts of the beater 3 with a head of cabbing, they have a minimal effect on it, which excludes damage to the head when it is moved to the cutting unit.

Subject invention

A cabbage harvesting device comprising guides and a disk knife with a vertical axis of rotation, characterized in that, in order to move the cabbage heads to the disk knife, a beater with curvilinear blades covered with an elastic material is installed above the guides in front of the knife.
