Description

Mounted beet harvesters equipped with screw (auger) leveling conveyors are known.

A distinctive feature of the proposed machine is that its rotary working bodies (screw conveyors) are made in the form of asynchronous electric motors powered by alternating three-phase current from a generator mounted on a self-propelled chassis or tractor.

FIG. 1 shows a structural diagram of the machine, side view; in fig. 2 is a schematic diagram of the machine, a plan view; in fig. 3 - front view; in fig. 4 - screw equalizers in the section.

The machine can be trailed and can be mounted on a self-propelled chassis. The working bodies of the machine are: hauliers 2 (two for each row of roots) in the form of cone-shaped hollow bodies, facing tops 3 forward along the machine and sliding in between the floors on the soil. The outer sides of the 4 haulters are convex, and the sides 5 facing the beet roots are concave and slide along the heads of the roots, which lift towards the leaves (tops) and at the same time act as a tracking device for each section; undermining paws 6 (two for each row of roots) of a special form, providing extrusion (squeezing) of the undermined roots from the soil upwards; screw-leveling conveyors (one for each row of roots), each consisting of two hollow nakloppy parallel cylinders 7 with conical front ends 8. On the outer surface of each cylinder there is an edge 9 located on one cylinder along the right, and on the other on the left helix. The right and left cylinders rotate in opposite directions, as a result of which the tops of the undermined roots retract into the gap between the right and left cylinders and move in turns from the front (lower) end of the conveyor to the rear (BepxHejMy), dragging along with them the roots, which also abut with their heads in both cylinders, which gives them a uniform arrangement of

height. The cylinders 7 are at the same time movable magnetic shells (core-rotors) and, together with magnets 10 placed inside them (stators), form electric asynchronous motors; cutting devices that can be made in the form of cutting disks, straight knives, or steel tape; the root conveyor is a screw conveyor, which separates the tops separately and dumps it onto the surface of the floor, into bunkers or into vehicles. The rotating shells // and 12, as well as the shells of the cylinders 7, are also the cords rotated by the magnetic field created by the shells inside these shells, the stator magnets fed by three-phase current; haulm conveyor, also shchepekovy.

The machine is powered by an electric current from a generator 13 mounted on a tractor or self-propelled, if the tractor and the chassis are not electric.

Thus, the machine lacks a basic mechanical transmission and the usual scheme for moving the working shafts and working bodies by means of mechanical transmission, since its rotational working bodies are made in the form of electric motors and themselves transmit movements to the subsidiary bodies through a direct kinematic connection between we write.

Subject invention

An electrified beet harvesting machine consisting of two hollow cone-shaped boom lifters, characterized in that, in order to increase operational reliability, its rotary working bodies (screw conveyors) are made according to the principle of asynchronous electric motors powered by alternating three-phase current from a generator mounted on a self-propelled motor. tractor.
