Kholodyuk Oleksandr - Ph.D, Senior Lecturer of the Department of "Operation of a machine-tractor park and technical service" of Vinnytsia National Agrarian University (3, Sonychna St., Vinnytsia, 21008, Ukraine, e-mail: holodyk@vsau.vin. ua).

Annotation

The process of cutting is widely used during the stockpiling and preparation of fodder - the processing of stems by the direct application of the force that arises at the cutting edge of the knife. Almost 85% of stem fodder are ground fodder for the stockpiling of which the forage harvesters are used.

Grinding of leaf mass is one of the most energy-consuming operations in the general process of stockpiling and the final quality of the fodder depends on it. The energy intensity of the grinding process is influenced by both the constructive and operating parameters of the machine, the cutting pair, and the physical and mechanical properties of the leaf-stem mass. Therefore, the development of grinding machines, the biter-knife in particular, should be carried out on the basis of detailed studies of the process of cutting grass mass, taking into account the current power and energy parameters.

The object of the study in this article was the process of cutting a herbal mass with a biter-knife grinding machine containing an active disk knives.

The purpose of the work was to establish the analytical dependence of the destructive cutting force in the interaction of the blade of the disk knive of biter-knife grinding machine with herbal mass.

The task of the work was: to analyze the researches and publications on establishing the effort of cutting a layer of leaf stem and influence of various factors on its magnitude; to establish a mathematical model of calculation the critical effort of cutting a layer of grass mass with a cutting pair: double finger of the feed rotor - a disk knife during the cutting with sliding.

The research methodology was based on the analysis of the interaction of the working parts of the grinding machine with herbal mass using the methods of theoretical mechanics.

In the scientific work the interaction of single-blade blade of a disk knife of a biter-knife grinding machine with a leaf-stem mass is considered under the condition of double-backed cutting with sliding. The force interaction of the knife`s blade with the grass mass was analyzed and the dependence (3) of the calculation of the critical destructive cutting force Rkr was determined. From the obtained expression it is established that its magnitude is influenced by both the constructive parameters of the cutting steam and the technological parameters of the grinding machine. Also the magnitude of the destructive force is affected by the transformed angle of sharpening of the blade of the disk knife and the sliding angle.

Keywords: grinding, cutting, destructive effort, the energy consumption, disc knife, sharpening angle, sliding angle, grinding machine, stalk feed.
