| Popis: | The cost of production of sunflower is determined by the number of operations for its cultivation as well as the manufacturing charges for them. The extraneous matter content of the hopper sunflower heap is the factor that can increase the cost of sunflower production. In connection with that, it is advisable to reach the minimum values of the extraneous matter content in the hopper heap during sunflower harvesting. The article substantiates the design of the sieve with additional holes which is installed as an additional cleaning stage in the combine harvester. Adjustable sieve holes have a shape similar to the longitudinal shape of oilseeds. The area of the sieve hole can be adjusted depending on the type or variety of sunflower, which will significantly reduce the extraneous matter content in the hopper heap. To analyze the sieve performance, a check sample was made which was installed as an additional cleaning stage on the “Niva” SK-5-M-1 and “Vector 410” grain combine harvesters. The analysis is presented of the extraneous matter content in the hopper heap with the use of an additional sieve with a different area of adjustable holes and without it. |
