The invention relates to agricultural machinery, in particular to machines for harvesting beet roots.

The purpose of the invention is to improve the quality of cleaning root vegetables.

Figure 1 shows a side harvesting machine; 2 is a view A of FIG. 1.

The root-harvesting machine contains a frame 1 mounted on the running 2, excavating the working bodies 3, the beater 4, separating the working body 5 made of cleaning rollers, over the receiving part of which two cylindrical brushes 6 with elastic blades are mounted, and the rear part is made in the form of an open loop, inside which is placed a transverse auger conveyor 7. Above the screw 7 and the last roller of the separating working body 5, the shield 8 is mounted, and the discharge conveyor 9 is brought to one of the ends of the screw 7 The working tool 5 above the screw 7 forms two pairs of cantilever shortened rollers 10 equipped with spiral windings 11. The rollers 10 are made in pairs counter-rotating, and their spiral windings 11 have a variable pitch increasing in the direction opposite to the unloading conveyor 9. Behind the rollers 10 is installed flap 12. Works korneborochna machine as follows. Moving along the rows of root crops, digging out working bodies 3 extract them from the soil and the beater 4 transfers it to a separating working body 5, on which the root crops are being cleaned from soil and plant impurities. Root crops, moving on the receiving part of the separating working body 5, simultaneously experience the impact of qiVJ

Lindric brushes 6, which disperse a pile of root crops through the rollers and clean their side surfaces from adhering soil. In the rear part of the separating working body 5, the beet roots from the side opposite the unloading conveyor 9 immediately reach the auger conveyor 7, and the rest of them get on top of the shortened rollers 10, which, by their spiral coils 11, clean the roots and transport them in the opposite direction unloading conveyor 9, and further to the screw 7, which, advancing a pile of root crops inside the rolls, having the form of an open loop, along their axes, finally clears the roots from impurities, and unloading the transport p 9 loads them into a vehicle traveling along with a root-harvesting machine. Since the rollers 10 form pairs of counter-rotating working bodies, this contributes to the effective tightening of vegetable impurities between them, which break off and slide along the shield 8 and leave the machine. Variable pitch of spiral windings 11

FIG.

Rollers 10, increasing as they approach the ends of the rollers 10, avoid congestion of root crops coming in from different rows of root crops.
