Description

one

The invention relates to agricultural machinery.

Beet harvesters are known, including a main frame and successively located topper-removing device mounted on a movable frame, a root HEAD cleaner associated with the main frame, and digging a working member.

A disadvantage of the known combines is the installation of the root head cleaner on the main frame, as a result of which the cleaner copies the soil relief by means of the traveling wheels of the combine. Since the wheels are located at the back of the cleaner at a considerable distance, such a copy of the soil relief cleaner is insufficient.

The aim of the invention is to improve the quality of copying the topography of the soil with the cleaner HEAD of the roots.

For this, in the proposed combine, the HEAD cleaner is connected with the main frame by the hinge and additionally, by means of a tie, is also hingedly connected to the frame of the boom-removing device.

As a result, the soil relief is copied using the averaged signals from the traveling wheels of the combine and the copying wheel of the topper-removing device located in front of the cleaner. Since the relief of the soil is randomly intermittent2

nature, such a cleaner cleaner improves copy quality.

FIG. 1 shows the proposed beet harvester, side view; in fig. 2 and 3 - root head cleaner with a suspension mechanism for a combine.

The harvester includes a main frame 1 supported on the running wheels 2, a device 3 for automatic control over the rows,

a topper-removing device with a cutting device 4, a copying wheel 5 and a topper receiving elevator 6 mounted on a movable frame 7 pivotally connected to the main frame 1; conveyor 8 for loading the tops into a trolley attached to the combine, movable frame 9 pivotally attached to frame 1, with disc roots digging working body 10 and cam separator 11, auger cleaner

12, load elevator 13 roots in vehicles and rotary cleaner 14 HEAD roots from residues of tops in the root. The rotors of the cleaner are installed across the rows of beets and are located directly in front of the disk working body 10. The cleaner is hingedly suspended to the main frame 1 by means of link 15 and to frame 7 by means of link 16. Links 15 and 16 are fixed from the bottom on the sides of the U-shaped frame 17 of cleaner

14 and form an angle between them which changes with relative vertical displacements of the frame 7 and the main frame 1.

The lift of the cleaner to the transport position is carried out together with the lifting of the frame movement 7 by the hydraulic cylinder. Link 15 for adjusting the location of the cleaner above the soil surface, depending on the height of the root heads, is made of two screws, which are fastened with a nut. Works harvester as follows.

The cutting apparatus 4 cuts off the heads of the roots with the tops and supplies them to an elevator 6, which diverts them to the conveyor 8 for loading into a cart. Before digging, the roots are cleaned of the residues of the tops by the cleaner 14, which copies the soil relief by the running wheels 2 and by the copying wheel 5 of the topper-removing device. The treatment by the root cleaner, in addition to cleaning the heads from the residues of the tops, weakens the interrelation of the roots with the soil and reduces the amount of soil sticking to the roots. The roots dug out by disk horses are cleaned of soil and vegetable impurities on the cam 11 and screw 12 cleaners and are loaded into transport by an elevator 13.

Subject invention

A beet harvester comprising a main frame and successively arranged tops and toppers, mounted on a moving frame, a root head cleaner associated with the main frame and a working tool digging, characterized in that, in order to improve the quality of soil relief copying by head cleaner, It is connected with the main frame and additionally, by means of a pull, is also hingedly connected to the frame of the topper-removing device.
