Description

Machines are known for the formation of a ridge, on the frame of which there are two ploughshares, selecting the soil between the ridges, the conveyors feeding the soil from the plowshares, and the grinders used for sifting the soil. In the proposed machine, in order to lift the soil from the furrow and feed it to the ridges, an excavator was used, which guided the soil into two cylindrical mesh drums, installed with a slope in opposite directions and used for sifting the soil.

In the schematic drawing of FIG. 1 is a side view of the machine; FIG. 2- view of the excavator from above; FIG. 3 shows the layout of two excavators on the gr de, top view.

The machine consists of an excavator / equipped with scoops 73 digging up, the spool is equal to the distance between the middle of two adjacent rows. The excavator is equipped with a loading roller 2. The depth of the scoops is done by lowering the lower end of the excavator. The earth, lifted by an excavator, is poured into the funnel 3, from which the finger drums 4 5 are fed to the sides rotating in opposite directions. The fingers on the drums are arranged so that the fingers of one drum pass between the fingers of the other drum.

The ground loosened by the drums enters the craters, 6 and 7, which guide it into the cylindrical net drums 8 and 9. The drums are set with an inclination in opposite directions and serve to sift the soil. The small part of the soil passes through the mesh drums for a wreck, and clumps of earth through the edges of the drums enter the grooves. Instead of the funnels 6, 7, conveyors T4 can be supplied to feed the earth into the mesh drums, the use of which allows a significant reduction in the height of the machine. The drum is aligned with a rotating drum W, placed at the rear of the machine. The drum is provided with radially set fingers, the circumference of which is more than the translational speed of the maschina, due to which loosening and leveling of the ridge is performed. The walls of the furrow are aligned and compacted with shields // and 12. These shields, depending on the height, may be rearranged in one way or another, vertically.

In order to use the machine, for example, on such soils where boulders occur that are not placed in excavator buckets, the latter is set obliquely with respect to the line of movement of the machine (Fig. 2). With this installation of the excavator, its buckets are 13 to the side, thanks to which the stone picked up by the bucket will be thrown sideways. Instead of a single excavator, two excavators (Fig. 3) can be put on the cage with a tilt in opposite directions. Each of these excavators plowed only half a mill.

The arrows indicate the direction of movement of the machine.

The subject matter of the invention.

A machine for the formation of a string, characterized in that, in order to lift the soil from the furrow and feed it to the ridge, it employs an excavator that guides the soil into two cylindrical mesh drums installed in opposite directions with HaKJiO and sifting the soil .
