Description

The subject of the invention is an improved potato harvesting machine having a delivered inclined trellis screen of conical shape.

In the known potato harvesters of this type, equipped with knives for cutting tops, with a plow body for digging up potatoes and with an elevator for transporting the earth and tubers to the screen, the separation of potato tubers from the ground is not sufficient, and the screening device does not prevent small tubers from loss.

In the proposed potato harvester, the second rotating screen and a number of cylindrical rotating brushes are used as additional shaking devices, the conical screen is equipped with internal ribs, a cylindrical wall, and a shield with a potato outlet.

FIG. Figure 1 shows a perspective view of a potato harvester with a removed cutter; in fig. 2 is a plan view of the main screen and brushes.

The machine is mounted on frame 1, which rests on the front wheels 2 and rear wheels 3. Between the front wheels 2 there is a profile roller 4, designed for movement along potato crests and used to crush clods on its surface.

The front wheels are connected to the stand 5. With the help of a lifting mechanism enclosed in the casing 6, the frame 1 can be raised and lowered to regulate its height above the front wheels 2.

Behind the front wheels is plowshare 7, the leading edge of which can be straight or arcuate; The blade is mounted on frame 1 on supports 5, and its curved edge serves to trim the furrow.

The main screen 9 has the shape of a truncated cone, the smaller diameter of which, denoted by the number 10, is open for potato production. The roar is formed by concentric ring circles, separated from each other and attached to

slats 11, evenly distributed around the axis of the rumble.

The screen 9 is mounted so that it can rotate on an inclined forward axis 12 in the direction indicated by the arrow A. The screen 9 is provided with a central cylindrical wall 13 with radial ribs 14 set equal distances from each other and passing between the wall of the screen 9 and the cylindrical wall 13.

The ribs 14, which are partitioned, divide the screen 9 into several receivers, separated from one another and facilitating the movement of the tubers.

The space between the screen of the screen 9 and the cylindrical wall 13 at a distance from the plowshare 7 to the point where the potatoes are passed to the second screen 16, overlaps the bottom panel (bottom) 15 (Fig. 2). Thus, the tubers are retained from the receivers between the ribs 14 until they are unloaded from these receivers.

In order to avoid the heaping of the earth in the place where earth and potatoes arrive at the screen 9 from the coulter, a shaking device is provided.

The shaking attachment serves to better separate the land from the potatoes and pass it through the screen and consists of a mechanically driven brush mounted on axis 17.

The brush has a cylindrical shape and consists of three sections: section 18 having coarse bristles, sections 19 with thinner bristles and sections 20 with even thinner bristles.

For further sifting and separation from the tubers of the earth, a second rotating screen 16 is placed in the machine, which takes the potato tubers from the main screen.

The screen 16 (Fig. 2) is made in the form of a flat disk consisting of concentric ring hoops, which can be separated and strengthened in the same way as the screen hoops 9. With the screen 16, a mechanically driven brush 21 is brushed, potatoes are swept across the screen for transferring it from the screen to the base of the elevator 22, mounted on the back of the frame 1.

There are four main potato processing points in the machine: the first is the rising potato and the earth goes to screen 9; the second is where the ground and tubers are brushed. 18, 19, 20; a third — where potato tubers, along with a known amount of earth, fall on the second screen, 16; and a fourth — where a brush of 21 sweeps the tubers off the screen.

To clean the screen 9 from the ground, another cylindrical brush 23 is installed, rotating around the axis 24 and located directly behind the plow.

All working parts of the machine are driven by an engine located on the back of the frame 1.
