Description

The invention relates to a device for washing root and tuber crops and can be used in industrial production.

The purpose of the invention is to improve the quality of washing and simplify the design.

FIG. 1 shows a device for washing of root crops, the general view; in fig. 2 - section aa in figure 1

The device comprises a bath 1, a belt conveyor 2 partially disposed therein, the belt of which is equipped with brushes facing outwards, and a mesh conveyor 3 enclosing it with brushes 4 facing inward, a drive station common to both conveyors, consisting of an electric motor 5, a gearbox 6, chain drive 7, sprocket 8, drive sprocket 9 of the conveyor and drum 10 coaxially and rigidly mounted on a common drive shaft 11, and tension station 12, on a common shaft of which

the co-stars of 25 listed cleaning zones are also co-axially fixed in one daughter and the drum, the additional device significantly overlaps the cable transfer station 13, tera 3, loading device 14, Fixed fixing of the leading and

located on the tensioning device of the belt conveyor 2, the discharge device 15 installed in front of the tensioning device of the mesh conveyor 3, the shower device 16 above the upper branch of the conveyor 3 in zone 1 and the shower unit 17 located above the lower branch of the mesh conveyor 3 in the zone between the tension conveyor devices.

The machine works as follows

Through the loading device 14, the fruits are fed into the space between the conveyors 2 and 3, driven by the drive. During transportation, the fruit is exposed to the brushes of the conveyor 3, which moves in the same direction, but with a greater linear speed, as the diameter of its stars is greater than the diameter of the drum of the conveyor belt 2. Due to the different linear speeds of the belts of the conveyors 2 and 3, the fruit rotates. At the same time, they are moistened with water from the cooling unit 16. Subsequently, the fruits pass through bath 1, where they are thoroughly washed. In doing so, they turn over and fall on the lower branch of the conveyor 3, which is transported to the loading

to the device 15. Before unloading, the fruits are rinsed with water from a washing device 17.

With the aid of the coaxial arrangement of the two conveyors, zones of intensive two-sided processing of fruits are easily formed. Creating different cleaning zones is necessary to separate various types of soil from the fruit. For example, predry cleaning allows you to remove impurities that are easily associated with the fruit. To separate the adhering impurities, it is necessary to subject the roots in a wetted state to intense brushing. In the movement, particles of dirt serve as an abrasive working fluid, contributing to further effective cleaning. To remove light impurities, a calm water mirror is necessary, since only in this case the impurities will float up and can be removed. Presence of all

driven sprockets of the conveyor 3 on the shafts of the belt conveyor 2, the diameter of which is larger than the diameter of the drum 10, allows, firstly, to exclude either an individual drive of one of the conveyors or a chain or V-belt transmission, as well as a whole range of bearings, simplifies the design and reduces losses from friction in bearings; secondly, since the diameter of the stars is larger than the diameter of the drum, the speed of its transport branch is also linear. Due to the different linear speeds of the conveyors, the fruits rotate. In addition, when reloading from the belt conveyor 2 to the net 3, the fruit is turned over, therefore the possibility of one-sided cleaning is excluded.
