Description

The invention relates to agricultural machinery and can be used in machines for harvesting root crops.

Known harvesting machines [Beet harvesting machines / Yu.B. Avanesov, V.I. Bessarabov, I.I. Rusanov. - M .: Kolos, 1979.- 351 p., Ill. P.206-247], including the main frame, a rack with a digger fixed on it, two beaters, root-collection discs for transferring root crops to a screw cleaner made in the form of two sets installed in series, each consisting of two screws, a roller and a support bracket.

The disadvantage of such machines is the insufficient cleaning of the mass of root crops on the screw cleaner due to the lack of structural elements that change the direction of movement of root crops after the beater.

The purpose of the invention is to improve the quality of cleaning heap of root crops.

To do this, in the root harvesting machine, which includes the main frame, a rack with kopach mounted on it, root-picking discs, two beaters and a screw cleaner, made in the form of two sets installed in series, consisting of two screws, a roller and a support bracket, above the second screw of the front set a spring-loaded guide in the form of a gear partition is installed. The guide is placed above the second screw of the front set so that the small beets do not spread over the front of the cleaner, the toothed partition is the most advantageous guide design, because it does not allow dirt to stick.

Figure 1 shows a screw cleaner, side view; figure 2 is a guide, view a in figure 1.

The harvester consists of a movable frame 2, on which a stand 1 with a digger 14, a root intake 15, beaters 3 and 6 and a screw cleaner with a guide 4 are installed. The screw cleaner consists of two parts of the front and rear mounted on the movable frame 2, each part a set consisting of two screws 8 (12) and 9 (13), one drum 5 (10) and a supporting bracket 7 (11). Behind the rollers 5 of the rear section of the screw cleaner, a transmission beater is mounted 6. The guide 4 is mounted above the screw 12 of the front set.

The machine operates as follows.

When the machine moves, the diggers 14 dig and squeeze the roots, which are captured by the root-picking disks 15, are lifted by them and with the help of a beater 3 are transferred to the guide 4, then to the working surface of the screws 13, 12, 9, 8, being separated from the soil as they move along the screws and plant residues, the roots fall on the transfer beater 6, and from it to the longitudinal elevator.

The tops before the passage of the harvesting machine are cut off by the tops, loaded into the nearby transport and taken out of the field.
