Description

one

The invention relates to the mechanization of work in nurseries, in particular to machines for digging up plants.

Digging machines with active detachments are known, which include an undermining working body, a bar conveyor and a separating drum.

Also known vykonochnye machine, including digging a working body, bar conveyor and separating drum, made in the form of a cylinder with plate-shaped beams installed on its forming.

However, the low quality of root cultivation is characteristic of the known digging machines.

When seedlings and saplings of deciduous trees are undermined, the soil layer is strongly reinforced by the roots of plants and is poorly destroyed. Having passed through the separating drum, it, together with the plants, lies on the ground, and the soil sprinkles the plants again, making them difficult to select.

The purpose of the invention is to improve the separation of seedlings from the soil, which is achieved by separating the flow of plants from the soil flow so that the soil crumbles earlier, and the plants pushed out of the soil and raised by the children fall to the ground somewhat later and appear on the surface.

For this, the separating device is made as separate for each row of plant rippers - lifts, containing an annular base and

on both sides in chess order, the blades protruding beyond the base.

The machine comprises a frame 1 with a digging tine 2 and two bar conveyors 3, support wheels 4, a drive mechanism including a propeller shaft, a gearbox 5 and chain gears 6 and 7.

In the rear of the machine on the brackets 8 mounted shaft 9, driven in rotation by a chain drive 10.

Blade rippers-lifters are mounted on the shaft, including an annular base 11, on which blades 12 are fixed on both sides in a staggered manner, with the blades protruding beyond the cylindrical part and increasing the width of the ripper-lifter.

During operation, the layer of soil cut by the plowshare enters the conveyor 3, is partially destroyed on it and transported to the ripper by m-lifts. Acting on rippers elevators, seedlings pushed out

they rise above the reservoir. Soil, times3

the loose blade is loose, showered, and the seedlings, which are larger in comparison with each other. fall to the ground later on, the soil of the soil, thereby facilitating their selection.
