FIG. one

The invention relates to agricultural machinery, in particular, to devices for isolating seeds from fruits, and mainly pumpkin crops.

The purpose of the invention is to reduce the loss of seeds.

FIG. Figure 1 shows a machine for isolating seeds from fruits, open, longitudinal section; in fig. 2 shows section A-A in FIG. one.

A machine for isolating seeds from fruits consists of a feed hopper, a chopping and separating device.

The grinding device 1 contains a drum 2 with teeth 3, a counter-tooth 4, a conveyor screw 5 with left and right windings, and a tray 6.

The separating device 7 consists of a perforated drum 8 with edges 9, the cross section of which has the shape of a regular polygon with a vertex angle of 120-150 °. The 15 unit 8 is mounted on the rollers 10 and the support 11 in the frame 12 mounted on the frame 13 with the pallet 14 by means of hinges 15 and the adjusting device 16. Inside the drum 8 there is a shower device 17 with a protective hood 18 installed above the damping device with its nozzles overlapping, outside - external shower device 19.

A machine for isolating seeds from fruits is as follows.

Fruits to be processed are fed to the feed hopper of the chopping device 1, where they are crushed by the drum 2 with the teeth 3. The chopped mass (pile) by the screw 5 goes through the tray 6 into the perforated drum 8 of the separating device 7. When the drum 8 rotates, the pile is caught by its edges moves up, held on to them by friction and centrifugal forces. Reaching the limiting angle

the ascent, the heap is detached from the face, turned over, falls, picked up by the next face and the process is repeated many times. In this case, the heap is intensively moved, the seeds are separated from the total mass, and are washed away under the action of water jets from the nozzles of the perforating device 17.

By tilting the rotating drum, the heap is moved to

The unloading zone, with the separated seeds passing through the perforations in the edges of the drum 8 and accumulating in the pan 14, and the waste leaves the drum and is sent to the waste collector.

Cleaning the drum 8 is carried out with water supplied through the nozzles of the external shower 19. At the same time, the protective visor 18 prevents the nozzles of the damper 17 from getting into

on them are plant fibers.

The angle of inclination of the drum 8 relative to the horizon is set by means of the adjusting device 16 and depends on the type of product being processed.

The use of a machine to isolate the seeds from the fruit reduces the loss of seeds.

Claims (2)

1. A machine for isolating seeds from fruits, containing a hopper, a chopper and a separator made in the form of a perforated drum with a douche device, characterized in that, in order to reduce seed losses, the cross section of the perforated drum has the shape of a regular polygon with an angle at verchune 120-150 °. 2. The machine according to claim 1, characterized in that the separator is provided with a protective visor mounted above the shower head. device with overlapping its nozzles. one nineteen to. 2
