Description

FIELD OF THE INVENTION The invention relates to agricultural machine building, namely to machines for post-harvest and preplant processing of potatoes.

The aim of the invention is to increase productivity by reducing downtime.

FIG. 1 depicts a potato sortizer point (when sorting tubers

into three fractions), general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - the same, with displaced shafts with figured rollers; in fig. 5 is a fragment of the image in FIG. 2 with displaced shafts with figured rollers; in fig. 6 - a fragment of a potato sorting station moved in the E direction

The potato sortiranal ITEM includes a loading conveyor 1, an additional bunker 2 and one hopper 3 and A for storing unassorted and sorted potatoes in one row and a bunker 5 adjacent to the last one, sorting blocks 6 and 7 located under them, consisting of feeding conveyors 8 and 9, the sorting surfaces 10 and 11, made of shafts with shaped rollers 12 and 13, mounted for movement along the sorting surfaces and located under the sorting surfaces of the exporters 14 and 15, installed under the sorting surface with the possibility of movement in the longitudinal direction, pitched trays 16-19, Bunkers 2-5 are equipped with respectively receiving hatches with shutter-descenders One of the ends 24 of the conveyor 14 is located above the feeding conveyor 9 of the second sorting unit 7 and the other end 25 is located above the access hatch 20 of the additional bunker 2, the Conveyor 14 is reversible. The loading conveyor is perpendicular to the longitudinal axis of the transfer conveyor 14, and the hopper 5 is installed on the side of the loading conveyor,

The potato assortment is a hot item as follows.

It is common for all the considered items of work of the point that small non-commodity tubers with a width of less than 35 mm are allocated through the corresponding equipment at the beginning of the process flow, therefore, during the 1 s loading conveyor, the autumn and spring sizes in width from 35 mm and above.

During the work of the Xfthofelesrtiravalny point in the fall, according to the first / second, the tubers are divided into two fractions on the release of seed tubers with a width of 35-61 mm (Fig. 1, 3, 5, 6 and 7), while between the figured rollers 12 (Fig. 3) gaps 26 equal to 61 mm should be installed, and by moving the shafts with the figured rollers 13 in the D direction (Fig. 5) a gap 27 is formed between the similar end of the feeding conveyor 9 and the shaft with the Figured rollers 13.

The source material from the loading conveyor 1 p-opupag on the feed conveyor 8, sorting the surface 10, with which the largest (non-seed)

tubers with a width of more than 61 mm coming down through slit 28 through pitched tray 17 and receiving hatch 21 are diverted to bunker 3, and the passage (tubers 35–61 mm wide) goes through gaps 26 to transfer reversing conveyor 14, from the end of which further to the feeding-flanger 9, through the slit 27 through the pitched tray 18 to the transfer conveyor 15 and from its outgoing end 0 29 through the receiving hatch 23 - into the bunker 5. Seed tubers are fed into the bunker 4 by moving the transfer conveyor 15 in the direction of the arrow E (Fig. 6) with 5 tubers and cher Slit 27 (Fig. 7) through cattle chute 18 and receiving hatch 22 is fed to bunker 4. Bun / zra 2 loading is provided by reversing the transfer conveyor 14, in which the passage of seed tubers from the sorting surface Yu is directed from the end 25 of the conveyor 14 to the reception hatch 20.

During the operation of the potato sorting station in the fall according to the second variant, the corresponding filling of the bunkers with food tubers, separation into fractions is not performed, and the shafts with figured rollers 12 are moved in the direction of arrow G (Fig. 4) to form a slit 30 between the similar end of the feed conveyor 8 and the shaft with Figured rollers 12.

The source material from the loading conveyor 1 enters the additional conveyor 8 and from its similar end through the slit 30 through tray 16 to the transfer reversing conveyor 14. The subsequent movement of the flow of food tubers and filling them with bins 2, 4 and 5 0 is no different from the considered conditions in the first embodiment for the isolation of seed tubers.

During the operation of the potato sorter, in the spring according to the third variant, 5 bins are filled with tubers of certain planting fractions (Figs 1, 2 and 3), for which by moving the shafts with figured rollers 12 (Fig. 3) along the sorting surface 10 must be gaps 26 are set equal to 53 mm, and, respectively, for the sorting surface 11 between the shafts with figured rollers 13 (Fig. 2) - gaps 31, different 45 mm.

The source material (seed pits, selected for storage in the fall of 35–61 mm) from the feed conveyor 1 enters the feeding conveyor 8, grading surface 10, from which coarse tubers with widths of 53–61 mm are similar.

The pitched chute 17 and the receiving hatch 21 are retracted into the bunker 3, while the passage (tubers 35–53 mm) through the gaps 26 enters the transfer conveyor 14 and from its end 24 it goes to the feeding conveyor 9, which sorts the surface 11. tubers of medium size with a width of 45-53 mm coming down through slit 32 through cattle tray 19 and receiving hatch 22 are fed to bunker 4, and the passage (tubers of small fraction 35-45 mm) goes to transfer conveyor 25 and from its end 29 - 23 Bunkers 5 in the reception office.

If, on average, it is acceptable to assume that in the total mass of the initial potato, the fines are about 10%, then subject to other mandatory indicators of the demand for planting material, it is possible to use such a mixture of medium and fines for planting. In this potato-sorted item, such a mixture can be a sub-product of the sorting device 6 delivered to the transfer conveyor 14. By reversing the conveyor 14, this mixture of medium and fine fraction from the similar end 25 through the receiving hatch 20 enters the hopper 2.

Using the proposed potato assortment point, during the autumn post-harvest period, significantly reduce the time required for the breaks required to rearrange the processing equipment placed above the bunkers during the transition from isolating food tubers to sorting seed seed, and vice versa. The location above the bunkers 2-4 of the sorting devices 6 and 7 of the transfer conveyor 14, the receiving trays with descent dampers 20-22 remains unchanged both in the autumn and in the spring periods of the operation of the potato sorting station.
