Description

The invention relates to agricultural engineering, in particular, to devices for washing root crops.

A device for washing root crops is known, including a washing bath, a disk with activator blades and an auger enclosed in a casing, and also an upper additional and a lower main nozzle installed on a vertical drive shaft. At the same time, the intake part of the casing is made in the form of a perforated cylinder passing through the hole of the upper additional nozzle. The lower main nozzle is located under the upper nozzle and is made to form a cavity for water supply from the pump through the pipeline. The inner wall of the main nozzle is perforated with holes, thereby forming a cone annular sprinkler. From below, a cylindrical guide is attached to the lower main nozzle, connected by a side window made in it. A loading window is located in front of the guide. (Utility model patent of the Republic of Belarus No. 9873, A23N 12/02, 07/17/2017) [1].

The main disadvantage of this device is its complexity of design.

The closest technical solution, chosen as a prototype, is a device for washing root crops, including a washing bath, mounted in it on a vertical drive shaft auger with an unloading window enclosed in a casing, as well as an intake bell, made driven and in the form of a hollow truncated cone, facing down with a large base, equipped with blades from its inner surface and installed with a gap relative to the screw casing (AS USSR No. 1184516, A23N 12/02, 06/02/1983) [2].

The disadvantage of this device is that it does not provide high quality washing of root crops.

The objective of the invention is to create a device that improves the quality of washing root crops.

The essence of the invention lies in the fact that a bar is fixed in the lower part of the shaft, and two nozzles in the form of tubes are connected to the bottom part of the bath, from its outer side, vertically and symmetrically with respect to the axis of rotation of the shaft, with the possibility of supplying fluid under pressure in the form of jets through them. having the ability to interact with the bar. At the same time, a pipeline with a valve is connected to the free ends of the nozzles. Taken together, this allows you to create a device that provides improved quality of washing root crops due to the additional impact on root crops with a pulsating fluid medium - compressed air or water.

In FIG. a device for washing root crops is shown, in particular, its general view in section is given, the dashed line shows the water level in the bath, the vertical arrows indicate the supply of fluid (air or water) under pressure P).

A device for washing root crops includes a washing bath 1 with a drain hole (not shown) and a loading window, an auger 5 installed in it on a vertical drive shaft 3, enclosed in a casing 2, and an intake socket 6, made driven and in the form of a hollow truncated a cone facing down with a large base, equipped with blades from its inner surface (not shown) and installed with a gap relative to the casing 2 of the screw 5. A bar 7 is fixed in the lower part of the shaft 3, and to the bottom of the bath 1, from its outer side, vertically and symmetrically with respect to the axis of rotation of the shaft 3, two nozzles 8 in the form of tubes are connected with the possibility of supplying fluid under pressure through them in the form of jets that can interact with the bar 7. At the same time, a pipeline with a valve (not shown) is connected to the free ends of the nozzles.

Device for washing root crops works as follows. Bath 1 is filled with water to the level (in Fig. it is shown by a dashed line) of the drain hole (not shown). At the same time, the loader conveyor (not shown) evenly feeds root crops into the tub 1, which, under the action of gravity, descend to its bottom part. The bar 7 and the screw 5, rotating with the drive shaft 3, create a rotational movement of water in the tub 1. The intake bell 6, capturing the water, supplies it from the bottom up, providing circulation. Root crops float up and are captured by auger 5, and water through the gap between socket 6 and casing 2 enters the zone of active washing of root crops, where it meets water flows that are in rotational motion from bar 7. Root crops, making a chaotic movement, are intensively washed. In addition, through the nozzles 8 in the direction of the rotating bar 7 is supplied under excess pressure fluid in the form of jets of air or water, which, intersecting with this bar 7, are interrupted. As a result, pulsating fluid flows are formed, which additionally act on the root crops and clean them. At the end of the washing process, the peeled root crops are fed through the 5 auger to the 4 unloading window.

Taken together, this allows you to create a device that provides improved quality of washing root crops due to the additional impact on root crops with a pulsating fluid medium - compressed air or water.
