The invention relates to the sorting of objects, in particular agricultural products, for example potatoes.

The purpose of the invention is to increase sorting efficiency by reducing fruit damage.

In FIG. 1 shows a fruit sorting apparatus in a general view; figure 2 is the same, a top view.,

The device for sorting fruits comprises a frame 1, a sorting surface in the form of rollers 2 mounted on the frame 1 with the possibility of rotation in one direction, devices for loading 3 and unloading 4 fruits and for cleaning the sorting surface in the form of pushers 5 mounted on both sides of the sorting surface with the possibility of reciprocating movements, with each roller 2 is installed with the possibility of alternating rotation around adjacent to

it faces 2 towards the discharge end of the sorting surface and vice versa by interacting with the pushers 5. The pushers 5 are mounted with the possibility of reciprocating movements by means of an endless traction member 6, enveloping the driven 7 and the leading 8 drums, the latter being connected to the drive 9 by means of a reversing mechanism 10. The axis 11 of rotation of the rollers 2 are mounted on levers 12, the axis of rotation 13 of which are mounted on the frame 1 coaxially to the axis 11 of rotation of the adjacent rollers 2. The frame 1 is made with polo latches 14 married rollers 2 located on opposite sides of the sorting surface. The latches 14 are made in the form of latches interacting with the stop 15, fixed on the endless traction body 6 in front of the pushers 5. The limit switches are installed on the frame00

16, 17 interacting with pushers 5 and associated with a reversing mechanism 10.

The device operates as follows ..

The sortable mass comes from the loading device 3 onto the rollers 2 of the sorting surface, which sort the mass into small to large fractions and feed it to the respective devices for unloading A of the fruit. When the fruits clog the sorting surface, the operator turns on the electromagnetic clutch of the reversing mechanism 10, which connects the actuator 9 to the drive drum 8 of the traction member 6. In this case, the pushers 5, acting on the rollers 2, rotate them around adjacent ones, the fruits sunk between the rollers 2 due to the displacement their center of gravity away from the deployable roller 2 to the axis of the adjacent one transfers the vehicle to the adjacent roller 2 and moves it into the next sorting cell between the rollers 2. After turning all the rollers 2 one after the other lenii to the discharge end of the sorting abutment surface 15 affects the position of the roller clamps 14 that secure the rollers 2 in the upper position. After that, the pusher 5 acts on the limit switch 16, which, using the reversing mechanism 10, changes the direction of rotation of the drive drum 8 and, consequently, the direction of movement of the pushers 5. When the catheters 5 return, when the latter move from the zone of interaction with rollers 2 emphasis 15 returns the latch 14 to its original position. In this case, the latches 14 come out of interaction with the rollers 2 and the latter, under the action of return springs (not shown), rotate to the initial (lower) position. After that, the pushers 5 act on the limit switch 17, which, using the electromagnetic clutch

the reversing mechanism 10 disables the drive 9 of the driving drum 8 of the traction member 6 of the pushers 5. Next, the operation cycle of the device is repeated in the same sequence CfH.

Using the proposed device allows for efficient and quality sorting of fruits.
