Determination of the parameters of the canonical working body of the straw chopper

The purpose of the research is to substantiate the parameters of the straw separator elevator. The scheme of the straw separator and its principle of operation are given. The proposed straw separator consists of elevators, a web, a shaker, a motion transmission mechanism, a sewing machine, a support and an electric motor. The results of experimental studies to determine the effect of the parameters of the straw separator on the friction composition of straw and its loss are presented. It is established that slope angles of the upper and lower blades of the elevators relative to the horizon are 360 and 560, respectively, the ratio of the slope angles of the elevators is 1.1, the ratio of the straw separator diameters is 0.74 and the number is 3, the sum of the lengths of the elevators is 2.75 m, and the frequency of the blade rotations is 400 m−1 should be.

The purpose of the research is to determine the power consumption of the process of grain grinding with a grinder. When conducting theoretical studies to determine the amount of energy spent on grinding grain during the operation of the grinder, the physical and mechanical properties of the grain, the parameters and mode of operation of the grinder, the energy consumption to overcome harmful resistances, to grind grain and to discard the crushed mass were taken into account. The technological scheme of the grain grinder is given. A mathematical dependence is proposed to determine the power consumption of the grain grinding process by a grinder. It has been established that the power consumption of a hammer grinder is mainly influenced by the number of hammers, the angular velocity of the hammer, the area of the front part of the hammer, the radius of the grinding chamber, and the physical and mechanical properties of the grain. As a result of the research, graphical dependences of power consumption and productivity on the number of revolutions of the hammer propeller were built.

“…As a result, sliding cutting is performed, according to the scheme of Fig. 3b, the active knife cuts like a punch [6][7][8][9][10][11][12][13][14][15]. In our case, we believe that the main factors in cutting the stem are the sliding cutting mode, with the pressure of the blade on the stem.…”

Analysis of the process of cutting the stem with a knife of a disk chopping apparatus

Jumatov

2022

The paper presents the results of the analysis of the process of cutting the stem with a disk-shaped knife, taking into account the physical and mechanical properties of stalk feed. The shell of corn stalks grown in the hot climate of our country is thicker and harder, and its coefficient of friction is somewhat lower. The smaller the angle of friction, the more difficult it is to clamp such a rigid piece of rod between the active and fixed blades. To avoid this condition, the stem must be pinched and sheared between the active blade and the passive blade. On the basis of kinematic studies, the conditions for ensuring the sliding of the rod along the blade of the grinding knife are determined in the work. Based on the physical and mechanical properties of corn stalks, the conditions for ensuring the sliding movement of the stalk along the chopper knife blade are considered.
