Abstract

The invention relates to agriculture, in particular to machines for liquid processing of root and tuber crops with protective-stimulating and other substances. The aim of the invention is to improve the reliability of the process. The device consists of a housing 1 in which the feeding device 2 is installed, an inclined conveyor 3 above which the sprayer 4 is located, behind which elastic blinds 5 are located. In the feed zone of the tubers a brush 6 is installed, enclosed in housing 7 with a scraper 8. When the tubers are made of the feeding devices are guided onto the conveyor 3 and roll along it and enter the spray zone, covered with the working fluid. As the upper branch of the conveyor 3 moves, the liquid preparation trapped on the belt between the tubers is continuously removed from it by means of a scraper 8 and a rotating brush and the same brush is re-applied to the surface of the tubers. Then, the processed tubers, moving to the end of the conveyor 3, meet with elastic curtains, meet with elastic curtains 5, and additional processing of the tubers occurs as a result of their interaction with the petals of the curtains. 2 Il.

The invention relates to agriculture, in particular to machines for liquid processing of root and tuber crops with protective-stimulating and other substances.

A device for liquid treatment of root crops is known, which contains a device for feeding tubers, a sprayer of the preparation and an element of additional redistribution of the preparation over the surface of the tubers, made in the form of brushes.

A disadvantage of the known device is the low reliability of the technological process, due to the fact that during operation of the device it is possible that the brush remains clogged with soil residues. i

The aim of the invention is to improve the reliability of the process.

This goal is achieved by the fact that in a device for liquid processing of root and tuber crops containing a device for feeding tubers, a dispenser of the preparation and an element of additional redistribution of the drug over the surface of tubers are made in the form of at least two elastic curtains with slits offset from each other with overlapping slits of one curtain petals another.

With this design, the reliability of the technological process is improved by eliminating the loss of the etching substance re-applied by the rotating brush and its more uniform distribution over the tuber surface.

Fig. 1 shows schematically the proposed device for liquid processing of root and tuber crops; Fig. 2 shows section A-A in Fig. 1.

The device consists of a housing 1 in which a feeding device 2 is installed, an inclined conveyor 3 above which a sprayer is located. At least two elastic curtains 5 in contact with the tubers are installed behind the spray gun in the course of the tuber movement. The shutters 5 are located across the conveyor 3 sequentially one after the other, are made with slits and are offset relative to each other with overlapping of the slits of one shutter by the petals of the other

In the feeding zone of the root crops i, the brush 6 is rotatably mounted, equipped with a drive 4, which serves to clean the conveyor belt 3 and pretreat the root and tuber crops. The brush 6 is encased in a casing 7 with a scraper 8. The upper branch of the belt conveyor 3 moves in the direction opposite to that of the tubers.

The device works as follows.

Potato tubers or any other j root crops are transported from the feeder, for example the inclined tray onto the conveyor 3, the CKa is drained along it, and once in the spray zone formed by the sprayer, 0 is covered with dispersed working fluid.

As the upper branch of the conveyor 3 moves, the liquid preparation that has fallen on the belt between tubers is continuously removed from it by means of a scraper 8 and a rotating brush 6 and the same brush is re-applied to the surface of the tubers. The casing 7 prevents the working fluid from getting on the walls of the housing 1. Next, the treated tubers, moving to the end of the conveyor 3, encounter elastic curtains 5 along the side surface of which flow the settled droplets of the working fluid applied by the rotating brush 6 when the tubers are reprocessed. Under the action of its own weight, the rolling tubers open the blinds 5, their petals are deflected, as a result of which a uniform re-; (the distribution of the liquid preparation with the curtain leaves on the surface of the tubers and their additional processing. The processed potato tubers roll off the conveyor 3 and are loaded into container 5 to receive the processed tubers or vehicles.

A device for liquid treatment of root crops makes it possible to prevent losses of a pre-chemical or protective-stimulating drug, to make more rational use of the preparation and to carry out additional processing of tubers by uniformly distributing the working fluid over the surface of tubers and to increase the productivity of the seed dresser by increasing the reliability of the technological process.
