Description

The invention relates to agricultural machinery, in particular to machines for harvesting bulbs of flower crops, and can be used for harvesting other root crops.

The purpose of the invention is to improve the quality of digging the bulbs and reducing the amount of soil in the excavated mass.

FIG. 1 shows a machine for harvesting root crops, predominantly bulbs of flower crops, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; in fig. 5 shows a section B-B in FIG. 3

The flower crop cleaning machine consists of a main frame 1 supported on the running wheels 2 and carrying successively installed devices 3 for removing the topsoil and forming a ridge above a row of bulbs, equipped with knives 4, onresravschik 5, digging up the working body - ploughshare 6, Battery separator 7, packer 8.

Adjusting the course of the tillage organs is carried out by changing the position of the pivot frame 9 by means of a lever mechanism 10. The front part of the pivot frame is equipped with a pivot scrap 11 for adjusting the direction of movement and is supported on a copying mechanism-wheel 12. The device 3 is made in the form of an auger, i-iero direction of rotation opposite to the working stroke of the machine, and carrying the way out from the outside

in the middle part of the auger there is a constant height lower than the height of the auger end windings, while the knives 4 are mounted on the winding in the transition zones from the middle part to the end parts of the auger with the protrusion of one end of the knives beyond the maximum outer diameter of the latter.

The machine works as follows. When the machine moves across the field, the copying wheel 12 (Fig. 1 and 2), located in the aisle, supports the established depth of processing by all working bodies. Rotating against the direction of the working movement of the unit, the cutting step auger with the edges of the turns of the central part, which has a smaller outer diameter, cuts off the soil layer with the sheet part of the spread parallel to the plane of the bulbs and together with the knives 4 (Fig. 5) and the end turns made with a large outer diameter, they form a crest of a flat-cutaneous shape with grooves at the base, saturated with bulbs. Stems, leaves and plant residues along with the surface layer of the soil are thrown into

 between (fig. 3). The formed comb is easily captured by the roller presses.

5 in the grooves at the base and evenly compressed, which allows to obtain a loosened soil layer with bulbs, which is fed to the digging depth

6 (Fig. 4). Elevator separator 7 produces a separation of the pile and delivers the bulbs in the filling device 8.
