MPO-50: description, purpose, principle of operation

Today, do without grain cleaning machinespre-processing can not be any agricultural enterprise, focused on the cultivation of cereals. Among all the variety of mechanized means, the leading position is occupied by MPO-50 - a machine capable of working with a wide range of agricultural products.

Pre-treatment machine MPO-50

The presented equipment relates to technologygeneral purpose, which is designed for the primary removal from the grain mixture of various impurities - pieces of stems, leaves, chaff, large pollutants. It is the first "meets" harvest harvested harvesters, and the quality of its work depends on the condition of the product, ready for sale. Pre-treatment is carried out before the seeds are dried and stored for storage.

The machine MPO-50 is able to work with many kinds of cultivated plants, and in production it is often used for processing:

1. Croup: millet, buckwheat, rice, corn.
2. Legumes: peas, lentils.
3. Cereals: rye, wheat, oats.

Equipment can be used as a part ofa complex of means, a mechanized conveyor line of stationary type PRK-50. The main purpose is purification from foreign products, weedy contaminants of grain heaps, which comes directly from the fields.

Essential elements

The action of the station for preliminary cleaning of cereals is based on shaking, sifting and removing small contaminants by air draft.

The main elements of the MPO-50 apparatus are:

1. Distribution screw.
2. Mesh conveyor.
3. Shaker.
4. Diameter fan.
5. Pressure and suction channels.
6. A settling ditch.
7. Throttle.
8. Screw for pollutants.

Due to the high degree of unification,The submitted elements simply find a replacement. This determines the advantage of the technique over similar machines - high maintainability. At MPO-50 spare parts can be purchased at all major Russian dealer centers.

Operating principle

The processing of the grain heap begins withentering it into the distribution screw. Here, the products are evenly distributed over the entire width of the moving net conveyor, which is assisted by a shaker. Seeds pass through the lattice together with finely dispersed pollutants, and the large rubble is carried away from the machine by a separate stream.

Purified in MPO-50 from large pollutants massenters the suction channel, where the fan, pumping air pressure, selects small particles and sends them to a settling chamber. The grain is not carried away by air currents, but by gravity it enters the next machine of the stationary line.

To correct the cleaning process, adjust thea throttle valve that controls the pneumatic pressure pumped by the fan, and a mesh conveyor with different cell diameters is installed. The "honeycombs" are smaller, the better the treatment is.

The machine of preliminary clearing of grain МПО-50has proved itself in a complex with primary purification stations ЗВС-20 or installations BIS-100. Together they are used both in the full cycle of cleaning grain, and before drying them for storage.
