Self-mobile cleaner of heap grain thrower ОВС-70МP

ОВС-70МP heap cleaner works as follows:

1. From the pile, a heap of grain through the loading elevator enters the receiving chamber, from which it enters the mesh conveyor in a uniform layer.
2. A grain pile passes through a mesh conveyor and is separated from large impurities.
3. Large impurities are discharged from the machine to the left and right along the ОВС-70МP conveyor.
4. Grain heap containing light impurities, after the conveyor enters the divider, which shares the outgoing flow of grain with light impurities to improve the cleaning of the grain material in the suction channel. The air stream created by the fan passes through the grain stream, picking up light impurities. Airflow is adjustable. This is the most effective way to remove light impurities, the so-called fluidized bed of grain.
5. In the sedimentation chamber, light impurities are separated from the air flow due to centrifugal force. Clean air enters the fan again, and light impurities are removed by a screw from the machine to the right in the direction of movement of the machine.
6. After the suction channel, the cleaned grain is unloaded from the machine through a special chute to a height of 3 meters or flies through the trimmer pipe to a height of up to 9 meters (adjustable).
7. The ОВС-70МP operator can change the direction of grain unloading by turning a special trough 360 degrees or a trimmer 254 degrees around its axis.
8. Grain from the gutter can be sent directly to big bags, bins, etc.

Advantages of ОВС-70МP in comparison with ОВС-70M and ОВС-70P:

• ОВС-70МP - a more versatile self-propelled grain cleaning and loading complex, combining the advantages of both ОВС-70M and ОВС-70P;
• from ОВС-70МP, the cleaned grain can not only fly out through the trimmer pipe as in ОВС-70M, but can fall out down into the trailer, big-bag, hopper or to the sides along a special trough like ОВС-70P;
• less power consumption and less damage to grain in comparison with ОВС-70M when unloading grain from ОВС-70МP through the gutter;
• unlike ОВС-70P, the ОВС-70МP machine has a trimmer with a pipe that allows unloading grain to a height of 9 meters and a distance of up to 25 meters.

Advantages of ОВС-70МP in comparison with other machines for cleaning and loading grain:

1. A pile of grain from the pile through the loading elevator enters the ОВС-70МP receiving chamber, from which it enters the mesh conveyor in a uniform layer.
2. A grain pile passes through a mesh conveyor and is separated from large impurities.
3. Large impurities are discharged from the machine to the left and right along the ОВС-70МP conveyor.
4. Grain heap containing light impurities, after the conveyor enters the divider, which shares the outgoing flow of grain with light impurities to improve the cleaning of the grain material in the suction channel.

6. After the suction channel, the cleaned grain is unloaded by the conveyor from the machine either into the trimmer, from where it flies out through the trimmer pipe, or poured down into the trailer or to the sides along a special chute that rotates 360 degrees.
