Physical-mechanical and technological properties of eroded soils

The process of smooth plowing with the turnover of layers within its own furrow is characterized by high energy costs due to the interaction of the plow body and the plow in conditions of blocked cutting. The purpose of the research is to substantiate the type of the second-rear body of the frontal plow. The proposed front plow for smooth plowing contains twin screw housings, first-row colliders, rear screw right- and left-turning plow housings, second-row colliders. Screw right- and left-turning plow housings are equipped with mirror-mounted screw shortened stabilizing plates. The transverse distance from the field cutoff to the front of the stabilizing plate is greater than the width of the body grip. As a result, the rear bodies work in a semi-open furrow, which helps to reduce the traction resistance of the plow. The results of experimental studies to substantiate the type of rear enclosures are presented. Experiments were carried out with the following types of rear housings: cultured, semi-screw, screw and screw housing with a guide plate. It is established that when performing the rear screw housings and equipping them with guide plates, the quality indicators of the plow fully comply with agro technical requirements. At the same time, the degree of embedding of plant residues and the height of irregularities is 92-95% and 4.3-5 cm, respectively.

The purpose of the study is to substantiate the parameters of the deep-loader of the mole-drainage gun. A diagram of a mole-drainage gun is given. The main working parts of the mole drainage tool are a deep loader, a knife, a rope and a drainer. Analytical dependences are obtained for determining the main parameters and traction resistance of the deep-loader of the mole-drainage gun. Theoretical studies have established that for high-quality loosening of the soil with minimal traction resistance, the height of the deep digger should be 90 cm, the width of its chisel is 7 cm, the angle of the chisel to the horizon is within 26-320, the length of the chisel is 11.5 cm, and the sharpening angle is 250. Installing a knife on a deep-loader increases the density of the dredge wall by 1.45-1.48 times, the depth of the dredge laying by 1.15 times, while the traction resistance of the mole-drainage gun decreases by 12.9%.

“…In some farms, feed grinding is done using manual feed grinding machines due to the lack of grinding machines. Due to the high power, metal and material volume of these feed grinding machines, their use dramatically increases energy consumption and other costs [11][12][13][14][15][16][17].…”

The rotary crusher allows you to qualitatively grind pressed roughage. The authors proposed and developed an improved technological scheme of an impact crusher equipped with two beaters for dosed transfer to the grinding chamber. The impact crusher consists of a transfer chute, metering beaters, a chopping chamber, a rotor, chopping knives, fixed knives, an exit chute, a feed bin and an electric motor. The efficiency of work is determined by the following parameters: length, width and thickness of knives, rotor speed. The purpose of the work is to substantiate the parameters of the rotor and its knives. Analytical dependencies are obtained to determine the parameters of the knife. Theoretical studies have established that the minimum length of the knife should be 6.9 cm, the width of the knife is 50 mm, and its thickness is 4 mm. A model for the theoretical calculation of the probability of grinding roughage of the required size within the limits of zootechnical requirements has been obtained. Based on the calculations, the probability of cutting the feed of the required size, depending on the number of rotation of the rotors, was established.
