Description

Separators are known for separating soil lumps from sugar beet roots. In such separators, slaty conveyor feeders are used and the heap separation is made according to the size of the root diameter.

In the proposed separator, for separating small soil lumps with a diameter of less than 0.40-0.46 from the length of the smallest root on the length of the first group of feeder-feeders, a resetter is used, made in the form of two parallel conveyors with brackets attached to them, sequentially entering between the slats conveyor feeders.

To separate large soil clumps from the sugar beet roots, at the end of the second group of conveyor feeders, a flip valve with an electromagnetic actuator acting from the photo relay is placed.

FIG. 1 shows a structural diagram of the described separator, side view; in fig. 2 is a top view.

The separator consists of a frame /, two adjustable side shields 2, two parallel slatted conveyors-feeders 3 for the first cleaning, a separating movable comb 4, a leveler 5, a resetter 6, two parallel conveyors-feeders 7 for the second PTS-source, a photo relay 8 and a flip valve 9 .

The heap of roots along with soil lumps enters the slaty conveyor feeders of the first cleaning and is divided into two parallel streams by a movable comb, which moves in one direction with the conveyor feeders, but at a slightly higher speed. Due to the difference in speeds, as well as due to the presence of side shields, the beet roots are arranged so that their axes coincide with the flow direction on the feeder conveyors.

The single-layered arrangement of the beet roots and soil lumps on the feeder conveyors is provided by an equalizer, the rotating blades of which are provided with an elastic guide.

The ejector consists of two parallel conveyors with U-shaped brackets mounted on strut-and-roller chains. The distance between adjacent staples is approximately equal to one third of the length of the smallest beet root.

The conveyors of the dumper are moving in the direction of movement of the conveyor-feeders of the first cleaning and with equal speed. At the same time, the U-shaped brackets of the dumper enter the spaces between the slats of the feeder transporters, remove the last beet roots and large soil clumps, which are then transferred by means of rotating rollers 10 to the conveyor feeders of the second cleaning. The soil clumps left on the conveyor-feeders 3 of the first cleaning, having the size of the smallest root in the diameter up to 0.40-045, are dropped when the conveyors move further. Beet roots and large soil clumps, moving with second-feed transporters, pass under the photo relay. At the same time, they are illuminated by illuminators // and reflect light on photocells 12 connected to amplifiers 13 and electromagnet 14. Beet root, falling into the equipped conveyor belt of feeders, reflects a stronger light flow on the photocell than the soil bundle. the photoelectric beet root is triggered, the electromagnet 14 is turned off and the released flip valve 9 is under the action of a spring and its own weight is pulled to the lower position, sending the beet root to the bunker 15. Soil lumps, While there is less light, the photocell does not trigger, the electromagnet remains on and keeps the flap in the upper position (in Fig. 1 - shown by dotted lines). At the same time, soil lumps, approaching the end of the conveyor feeders, are dropped, mine is a bunker.

The described separator provides for the mechanization of the process of removing soil lumps from a pile of sugar beet roots when harvesting with the last beet-harvesting manshna with pruning the foliage on the vine.
