This paper reports a study aimed at increasing the intensity of grinding of the stems of coarse-stemmed crops by establishing the influence of the orientation of the cutting edge of the cutter-shredder knives on the quality of the technological grinding operations.
Analytical dependences of the planar movement of the roller-shredder were established and it was determined that for rollers with knives, the cutting edge of which is directed in the direction opposite to the direction of rotation:
– exceeding the value of the vertical components of the total forces of resistance of the knives, which made it possible to increase the values of forces, and, as a result, more intensive destruction of the layer of plant remains;
– exceeding the values of the driving force of the knives based on the dependence of the driving force on structural and kinematic parameters (roller weight, drum radius, blade height, blade inclination angle, acceleration).
Experimental studies have established an excess of up to 20 % of the quality indicators of milling sunflower and corn stems with roller knives, the cutting edge of which is directed in the direction opposite to the direction of rotation.
The average number of crushed pieces of corn stalks in the range of less than 50 mm is 13.6 % higher in the combined unit, the cutter blades of which are directed with the cutting edge in the direction opposite to the direction of rotation.
It was established that with zero and 3.92 kN (400 kg) additional loading, an increase in speed from 7.45 km/h to 13.6 km/h leads to a decrease in the values of the average traction resistance. The highest value of traction resistance was set at a speed of 13.6 km/h and an additional load of 7.84 kN (800 kg). The lowest value of traction resistance was established at zero additional load and a speed of 22.0 km/h, which is 21.5 % less than at a speed of 7.45 km/h and 14.1 % less than at a speed of 13.6 km/h.
