Description

(54) SETTING FOR TREATMENT OF ROOT FROZEN BEFORE BOOKMARK THEM FOR LONGARY STORAGE

one

The invention relates to a device for processing root crops before laying them for long-term storage and can be used in agriculture.

A known device for treating root crops before laying them for long-term storage comprises a receiving hopper, a pressurized water supply system, a device for washing root crops, a conveying and rinsing device 1.

A disadvantage of the known device is the low processing efficiency.

The aim of the invention is to increase the processing efficiency.

The goal is achieved by the fact that a coating unit, made in the form of a container with a rotary conveyor with blades and trellised sections, is placed in it behind the rinsing device.

FIG. 1 shows the installation installation diagram; in fig. 2 - equipment layout; in fig. 3. - section A-A in FIG. one.

The installation includes a receiving bunker 1, a sorting unit 2, trays 3 and 4 washing of root and tuber crops and a coating unit 5.

Along the perimeter of the bunker 1, which has inclined walls at its top, collectors 6 are located for supplying pressurized water, in the lower part on one of the walls there is a hole 7 connecting the bunker 1 to the water supply 8, and on the opposite side is a narrow hatch 9.

In tray 3 of the prewash, the bottom of which is inclined and stepwise with respect to the horizontal plane, conveyors 10 and 11 are installed, having transverse elastic pegs, one of the conveyors is located under the unloading hatch 9 of the bunker 1, and the other is at an angle to the sorting unit 2

The sorting unit 2 contains a belt sorting surface 12 with

20 adjacent unloading conveyors. 13, to which the bulkhead tables 14 are installed, equipped with side conveyors 15 and inclined grooves 16 for feeding the root and tuber crops to the tray 4

final wash. Chute 16 and tray 4 are pressurized with water.

Under the belt sorting surface 12 and the lateral conveyors 15, conveyors 17 and 18 are installed to feed the uncortical roots to the bunker 19.

In tray 4 of the final washing, the bottom of which is made with respect to the horizontal surface inclined and stepped, a conveyor 20 for feeding the root and tuber crops to the coating unit 5 is installed.

Trays 3 and 4 are connected to the water supply system 8 and have drainage holes for the dumping of water into the sump.

The coating unit 5 is made up of a rotary conveyor 21 mounted on a rotating shaft, the lower part of which is immersed in a solution bath 22.

The blades 23 (Fig. 3) are located on the outer surface of the rotary conveyor 21, and transverse ribs 24, which form sections with the side surfaces, are located on the inner surface.

The rotary conveyor 21 is equipped with a discharge funnel 25, under which is installed the belt conveyor 26 unloading of root and tuber crops into the hopper 27.

The bath is equipped with a conveyor 28 (Fig. 2) for feeding the powder from the hopper 29 and an opening 30 connecting it to the water supply system.

In the lower part of the bath there is a rotating blade shaft 31 and a cleaning hatch 32.

The device works as follows.

Root and tuber crops are poured into the receiving bin 1, in which they are moistened with water that flows through the collectors 6 and. an opening 7 connecting the hopper 1 to the water supply 8. The sticking soil softens and a partial washing takes place. Wetting promotes better slipping of root and tuber crops along the walls of the bunker to the discharge hatch 9. By pressing water through the opening 7, the root and straw fields are displaced from the bunker 1 through the discharge hatch 9 to the conveyor 10, the speed of web movement of which is set depending on the plant capacity.

From the conveyor 10, the root crops are fed to the tray 3 of the prewash and the water flow is directed to the lifting bar conveyor 11 and the belt sorting surface 12, where the small fraction of the root crops is separated, to the bunker 19 along the conveyor 17,

and the remaining large roots are divided into two streams by discharge conveyors 13 and directed to bulkhead tables 14.

On the bulkhead tables 14, damaged and non-standard root and tuber crops are separated, which are sent to the bunker 19 along the side conveyors 15 and conveyor 18.

Large root crops from the pereboroh table 14 fall into the inclined chute 16 and the water flow is directed into the tray 4 of the final washing.

The rootstocks, moving along the tray 4 of the final wash, under the action of the water flow, undergo a final wash and enter the bar conveyor 20, where the water is separated and the root crops are fed into the sections of the rotary conveyor 21.

When the rotary conveyor 21 is rotated, the sections with the roots are submerged in the solution, lifted out of it and poured out of the sections into the discharge funnel 25 in the upper position, from which they are fed to the conveyor belt 26 and the store 27, and then into the vegetable store for long-term storage.

For preparing the solution forming the protective film, from the hopper 29 through the conveyor 28, for example, chalk powder is supplied to the bath and water in corresponding proportions through the opening 30. The resulting solution is continuously moved by the blades 23 of the rotary conveyor and the blades by the shaft 31.

The installation conducts effective processing of the root crops, which increases the IC preservation during long-term storage.
