Description

The proposed potato digger is designed for use in large farms with high productivity, for which purpose the machine is adapted for operation using tractor traction. In operation, the machine pre-cuts the tops under the root and throws it on two sides, after which the potatoes are excavated by a series of knives, set at intervals, in which double-sided turntables rotate, moving the excavated potatoes along the cuttings of the knives to the receiving bucket.

In the schematic drawing of FIG. 1 shows a side view of a potato patcher and FIG. 2 is a top view.

In front of the main frame there is a double-sided knife 1, which captures the width of three furrows of potatoes and is equipped with a double-sided blade 2. The blade of the knife is located at the depth of the tops of the tops from the ground and is intended to cut the tops of the tops and roll them to two sides. Behind the knife 1 there is a row of knives 3 with curved cuttings spaced at intervals, forming a type of grid,

curved upwards. On axis 10, driven by the chain transmission 11 from the axis of the running wheel of the machine, there is a double-sided row of fingers 4, which are included in the gaps of the knives 3, and designed to move the dug potato tubers up the grate up to the receiving bucket 5 of the bucket elevator 6, carrying tubers for endless ribbon grids 7, 8, 9, one above the other and intended for sifting off the ground and for sorting potato tubers.

The subject of the patent.

Potato digger with an elevator for lifting tubers on sorting screens, characterized in that the digging potato bushes are made in the form of a system of individual knives 3, forming a grid with its cuttings, in order to place the propellers of the wheels 4 rotated from the axis of the running wheels of the fingers 4, designed for transfer of tubers to the receiving bucket of 5 elevator 6.
