Self-mobile cleaner of heap grain loader  ОВС-70П

Serves as a grain cleaning machine
and grain loader. The main difference between ОВС-70П and ОВС-70M
lies in the fact that the refined grain is fed
conveyor not to the trimmer, but directly to the trailer,
big run or sleep enough. The advantage of such a machine
is minimal grain injury. However there is
and the disadvantage is the maximum possible height
for loading - up to 3,5 meters.

ОВС-70П - is a self-propelled high-performance hybrid of a grain cleaning machine and a grain loader. The main difference between ОВС-70П and ОВС-70M is that the ОВС-70П has an elongated unloading elevator, but there is no trimmer. At ОВС-70П, the cleaned grain is not conveyed by the conveyor to the trimmer, but directly to the trailer, big-run, hopper, or poured down.

Functions performed by the self-propelled heap cleaner ОВС-70П:

  • cleaning grain heaps of legumes, grains, cereals, ears, corn, sunflower, rapeseed, sorghum, etc .;
  • loading grain directly into vehicles with a side height of up to 3 meters;
  • loading grain into big bags, bags, bins, loader buckets, etc .;
  • mechanical shoveling of grain, accompanied by its simultaneous cleaning, as well as partial drying in open areas or granaries.

 ОВС-70П  operates in the following sequence:

  • a pile of grain from the pile along the loading elevator is fed into the receiving chamber, from there it enters the conveyor in an even layer;
  • when passing through a mesh conveyor, the grain material is cleaned of large impurities;
  • large impurities are discharged by the conveyor to the left and to the right of the ОВС-70П;
  • the pre-cleaned grain heap, which still contains light impurities, is sent to the divider, where the flow of grain material is divided to ensure better grain handling in the suction channel. Light impurities are picked up by the stream of air created by the built-in fan. This method is most effective for separating light impurities. Air flow rate adjustable;
  • getting into the sedimentation chamber, light impurities are released from the air stream under the influence of centrifugal force. The purified air is again supplied to the fan, and light impurities are discharged by a screw to the right of the ОВС-70П;
  • from the suction channel, the cleaned grain enters the conveyor and is further discharged from the machine through the chute;
  • ОВС-70П operator can quickly change the direction of grain unloading by turning the gutter.

Heap cleaner ОВС-70П self-propelled has a number of advantages, in comparison with other grain cleaning machines:

  • ОВС-70П independently loads grain into the car body, container or trailer or stores it. The participation of grain throwers, loaders, nori is not required.
  • ОВС-70П is a self-propelled (not stationary) grain cleaning and loading machine. For the introduction of its operation does not require additional costs.
  • ОВС-70П is a mobile ZAV, which can easily be moved to another current, granary, or even to another farm.
  • It features great performance. Depending on the type of grain, its moisture content and the degree of contamination, it can process from 50 to 90 tons / hour.
  • It carries out high-quality grain cleaning and its separation: according to specific gravity (using adjustable air flow, by the type of aerodynamic separators) and by size (using a grid with cells of different sizes).
  • The energy consumption for cleaning and loading is minimal and amounts to 0.2 kW / h per 1 ton of grain.
  • ОВС-70П performing grain cleaning, also performs its drying. The moisture content of the grain material is reduced to 2%.
  • During the operation of ОВС-70П, expensive maintenance is not required.
  • Provides minimal grain damage.

ОВС-70П2 ― аn improved model of a heap cleaner - ОВС-70П grain loader. ОВС-70П2 differs from ОВС-70П in the presence of an additional motor gearbox and an advanced remote control for turning ОВС-70П2 when moving. This facilitates the control of the ОВС-70П2 and allows you to easily change the direction of movement of the machine without the use of physical force. In ОВС-70П2 there is also the same steering wheel as on ОВС-70П (for manual control of ОВС-70M2 if necessary).
