OBC-25CB Self-propelled grain cleaner with a cyclone and a hopper

Stationary grain cleaner OBC-25S performs cleaning of cereals, legumes, sunflower, sorghum, rapeseed, corn, etc. Grain cleaner OBC-25S is installed in existing grain cleaning units or mounted separately. OBC-25S is equipped with a receiving chamber, an air-cleaning part, sieves, a feed waste screw. All working bodies are mounted on the frame. OBC-25S performs cleaning of grain and seeds using an aspiration system and sieves. The distributor divides the grain with impurities into two equal parts and directs it to the air channels. Airflow through the fan carries off light impurities. Larger impurities from the air stream are captured by the settling chamber. Further, the grain purified by the aspiration system falls on the upper and lower sieves. On sieves, the process of cleaning grain from impurities that differ from grain in size occurs. The sieves are cleaned with brushes. If necessary, OBC-25S can be additionally equipped with loading and unloading elevators, as well as a cyclone.

ОВС-70L is a self-propelled high-performance hybrid of a grain cleaning machine and a grain loader. The main difference between ОВС-70L and ОВС-70M4 is that the ОВС-70L has an elongated unloading elevator, but there is no trimmer and sieves. Cleaning grain of any humidity or contamination is carried out using an aspiration system and a mesh conveyor. For better grain cleaning, a self-propelled grain cleaner OBC-70M4L is used. At ОВС-70L, the cleaned grain is not conveyed by the conveyor to the trimmer, but directly to the trailer, big-bag, hopper, or poured down. Functions performed by the self-propelled grain cleaner ОВС-70L: - cleaning grain heaps of legumes, grains, cereals, corn, sunflower, rapeseed, sorghum, etc .; - loading grain directly into vehicles with a side height of up to 3 m; - 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.

OBC-25CE is a stationary grain cleaning machine equipped with unloading elevator additionally. Presence of such kind of elevator simplifies grain cleaning process and makes it possible transferring grain into vehicles, grain vessels, trailers, big bag etc. Machine can also be equipped with a boot elevator and cyclone if necessary. On customer request wheels can be installed to OBC-25CE that turns the unit into mobile one. OBC-25CE performs grain and seeds cleaning using an aspiration system and sieves. Spreader separates impure grain in two equal parts and directs it to air channels. Fan airflow takes light impurities out. Larger impurities are captured with settling chamber from air stream. After that grain purified in aspiration system comes to upper and lower sieves. At these sieves grain gets cleared of impurities kind of different size. Pure grain is collected at the bottom of OBC-25CE and unloaded with built-in elevator.

The OBC-25SC grain cleaner cleans any grain using 8 sieves and an aspiration system with a built-in cyclone. The installation of a cyclone at OBC-25SC made it possible to solve the problem of cleaning the air emitted by the OBC-25SC fan from dust and light impurities (small parts of leaves, grains, insects, sand, etc.). Previously, this was solved by installing a separate cyclone near the OBC-25S, conducting an air duct from the OBC-25S fan to it, and installing a clean air exhaust system from the cyclone. This led to significant additional costs and required a large free space. Now OBC-25SC with an integrated cyclone that successfully copes with cleaning a heap of grain, saves space and money. Additional advantages of the grain cleaning machine OBC-25SC: - high productivity with small sizes; - simple, durable design; - quick sieve change; - automatic cleaning of sieves with built-in brushes; - can be equipped with lifts, cyclone pipe and wheels.
