Description

Potato harvesters are known in which screen vibrations are communicated to sieves for better sifting of the earth.

The peculiarity of the potato potato described here is the presence of oscillatory movements in the podkapyvayush, their plowshares.

FIG. 1, 2 and 3 a two-row vibrating potato digger is shown in three projections.

The machine consists of the following main components: rollers /, vibrating sharers 2, screens 3, transverse conveyor 4, box 5 with rods, frame 6, transmission 7 and hydraulics 8.

In front of the plowshares 2 are rollers I, one for each row of potatoes.

The rollers 1 are connected to a screw device for adjusting the depth of stroke of the plowshares 2.

Ploughshare 2 vibrating consists of two twisted twin trough-shaped plowshares, hinged on frame 6 with the help of metal hangers and shock absorbers. Each of the plowshares 2 is welded from bars and right and left.

blades with double-sided sharpening. The gap between the rods 30 mm.

The vibrating shares of the plowshares 2 are connected by rods hinged on the plowshares and connected to the eccentrics located on the shaft of the box of the rods 5.

The transverse conveyor 4 consists of rubber-coated rods fixed on two parallel chains with a step of 38 mm. The chains are guided by special rollers and driven by sprockets mounted on the elevator drive shaft.

The frame 6 is welded from rectangular tubes.

Box 5 with shatunami is a gearbox with a conical pair. On the shaft of the box, eccentrics are rigidly mounted, which are connected to the plowshare 2 and the roar 3 pivotally. Thanks to eccentrics, the shaft of the box informs the ploughshare 2 and rumble 3 reciprocating motion.

Movement to the potato digger is transmitted from the tractor through a cardan transmission and sprockets.

bush roller chains. The potato digger rises to the transport position and lowers to the working position using hydraulics 8, controlled by the operator.

The two-row vibratory potato digger is designed for digging potatoes, separating the tubers (from the ground, tops and large stones) and placing them in a narrow ribbon.

When the machine moves along potato wards, the rollers crush soil clumps and partially destroy the relationship of tubers with stolons.

The layer destroyed by rollers is cut by blades of vibrating shares and mixed up along the inclined grate surface due to the pressure in front of the lying layers of soil and the inertial forces imparted by the vibrator.

In the process of moving upwards, the soil is partially sifted in the gaps (between the grate bars) at the share of the ploughshare.

Thus, the plowshares, undermining two clumps of potatoes at the same time, separate part of the ground, partially tear off the tubers from the stolons, and transfer the tubers with the remaining soil and tops to the vibrating screen.

On a roar, the ground is sifted, and the tubers with tops are inertia moving upwards.

At the end of the rumble, the tubers fall into the gaps between the topper-removing scallops, fall into the transverse elevator, where the earth is finally sifted, and the tubers are laid in the tape.

The botva, cut off from the tubers of potatoes, moves by inertia along the surface of the tops-removing scallops and is thrown back towards the harvested floor.

Large stones and lumps, moving along the surface of the toothed comb, are also thrown in the direction of the floor-0.

Described potato digger

can be used when harvesting turnips, carrots and table beets. When digging turnips and beets, there is no need to use a transverse elevator. The design of the described two-row vibratory potato-bakers has several advantages compared with the known potato-bakers: the wear resistance of parts is increased; provides work on all types of soils without sticking, as well as the separation of the tops and tearing of tubers from stolons; the labor required to harvest tubers after the passage of a potato-bastard is halved; The machine is serviced by a single tractor driver, which allows the trailer to be released,:;

The subject invention,

Claims (3)

1. A double-row vibratory potato digger consisting of two rollers, two paired bar trough-shaped plowshares, a screen, a transverse elevator, with a theme. That, in order to reduce traction resistance and better sifting of the earth, oscillatory movements (vibrations) are communicated to the engine using a cleat-crank mechanism, thereby ensuring that the ploughshares work on all types of soil without sticking and better formation, and also removes the tops and tearing tubers from stolons due to inertial forces., 2. The form of execution according to claim 1, is different from the fact that, in order to destroy lumps of earth, rollers having a concave surface are installed in front of the digging pins. 3. The form of execution according to claim 1, characterized in that, in order to reduce the vibration of the potato-bakers, rubber bushings are placed on the hanging fingers of the shares and the rumble.
