Description

The invention relates to forest machine engineering, in particular to machines for digging up seedlings when they are grown in nurseries.

The aim of the invention is to improve the quality of digging up plants and increase productivity when they are sampled from the soil.

FIG. 1 shows a digging machine, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2 (tapes of the soil layer with seedlings); in fig. 4 - shaft with knives; in fig. 5 - plowshare extension.

The excavator machine contains a frame 1 with support wheels 2, on which an undercutting bracket 3 with plowshare 4 is mounted. Under the windows 6 posted shaft 7 with knives 8 triangular shape. Each window 6 has a diamond shape.

The shaft is driven by the drive mechanism 9.

The machine works as follows.

During the movement, the staple 3 with the plowshare 4 undermines the soil layer from the bottom and from the sides. The soil stratum on the plowshare 4 and extension 5 first rises and then smoothly slides into the furrow. On the path of the formation along the extension 5, knives 8 act on it and cut it into several strips 10 (in relation to the number of rows of seedlings). The latter have a trapezoidal cross section that corresponds to the nature of the placement of the root system of plants in the soil. At the same time, part of the soil passes through windows 6, and ribbons 10 with plants descend along the inclined part of extension 5 to the bottom of the furrow.

After passing the machine, the plants remain upright due to the preservation of the soil around the root system and the smooth descent of the soil tapes along the inclined plane of the extension 5.
