FIG.

: The invention relates to agricultural machinery, in particular, to I machines for preparing the arable horizon of the soil for planting and combine harvesting potatoes.

The purpose of the invention is to improve the quality of crumbling and soil separation.

FIG. 1 shows schematically the proposed machine for preparing the floor for planting and combine harvesting potatoes; ; in fig. 2 - the same, top view; in fig. 3 - installation diagram of knives; in fig. 4 is a graph of the separation completeness e versus the ratio of the length of the knife Ln and the distance from the axis of turn of the disk to the first axis of the hinged attachment of the knife Re.

Masha) 1a to prepare the floor for planting and combine harvesting of potatoes includes successively mounted on the; I 1 supporting-copying rollers 2, working post 3, bar elevators 4 and 5 with rods 7. A cross conveyor 8 is installed behind the Elevat IpoM 6, directly below it, for laying stones in a pre-opened furrow. A cumulative device 9 is installed above the elevator 4, consisting of sections 10 and 11 symmetrically and mirrored relative to the longitudinal axis of the machine, consisting of 12 disks 13 mounted at an angle and to the axis of rotation of the shaft, on each of which knives are hinged 4, with the distance Emezda between the blades of the knives 14 of the adjacent disks 12 being 1.5 lumen d between the adjacent rod-: Kami of the elevator 4, and the ratio between the length of the knife Lii and the distance from the axis of rotation of the disk 11 to the axis of the hinge knife mounting 12 Ro is in the range of 2.3-2.5. Comrade device installed with the ability to adjust its height using, for example, the adjusting mechanism 15.

Maschina works as follows. When the machine moves, the undermining working body 3 cuts the soil layer and transfers it to the first elevator 4, where the soil lumps are separated and crushed by a lump-breaking device 9. The hinged knives 14 act on the soil layer, thus crushing the soil lumps to a size commensurate with the gap between the bars 7 elevators 4-6. At the same time, the knives 14 provide alternating displacements of the soil mass in the transverse direction, which also increases the separating ability of the elevator 4. The operation of the com-destructive device 9 takes place in the most favorable mode, when the knives 14 have a relative rotational speed, which coincides in direction c the angular velocity of rotation of the comradeal device 9.

The soil that has not yet reached the soil mass enters the elevator 5 for secondary separation. Thereafter, the remaining soil mass is transferred to the third elevator 6 for final separation, rather than sifted stones and hard soil clumps fall into. transverse conveyor 8, which lays them in a pre-opened furrow.

Claims (2)

1. A machine for preparing the floor of the planting and combine harvesting of potatoes, including a frame, supporting-copying rollers, digging up the working body, bar elevators, a transverse conveyor and. comrade device, characterized in that, in order to improve the quality of crumbling and soil separation, the comrade device is made in two symmetrically and mirror-like with respect to the machine longitudinal axis of the sections of the working members, each working member of the section is made in the form of a disk with hingedly mounted on it knives, the distance f between the blades of knives of adjacent discs and the distance d between adjacent rods of the elevator is determined from the ratio I l, 5d, and the ratio of the length of the knife to the distance from the axis Sheni shaft to the hinge axis attachment blade is in the range of 2.3 ... 2.5. 2. The machine according to claim 1, characterized in that the com-destructive device is installed with the possibility of its height adjustment. Fig.Z g, 5 fia. J g ////
