“…In the Y direction, the potato plant performs an up-throwing motion with a velocity perpendicular to the conveying separation device, and the motion trajectory is shown in Figure 8. Equations ( 12)- (15) show that the state of motion of the potato plant is related to the forward speed of the tractor, the conveying speed to the forward speed ratio, and the rotational speed of the vibration device. Select the suitable forward speed, the ratio of conveying speed to the forward speed, and the rotational speed of the vibration device to ensure the integrity of the potato plant.…”

In order to solve the current problems of time-consuming manual work and low harvesting efficiency during the harvesting of potato breeding trials and the inability of traditional harvesting machinery to meet the requirements of potato single plant harvesting, a single plant harvester for potato breeding with a combined excavation device and a conveying and separating device with alternating concave and straight units is designed. This paper analyzes the force, motion, and collision of potato plants in the digging transition stage and conveying and separating stage. The key factors affecting the rate of single plant integrity and the rate of injured potatoes are determined. A three-factor quadratic regression orthogonal rotating combination experiment is conducted with the rate of single plant integrity and the rate of injured potatoes as experiment indexes, forward speed, conveying speed to forward speed ratio, and the rotational speed of the rear-vibration device as influencing factors. Based on the experiment results, a mathematical regression model is established, and response surface analysis and parametric analysis are conducted to determine that when the forward speed is 0.65 m∙s−1, the ratio of conveying speed to forward speed is 0.98, and the speed of the post-vibration device is 11.52 rad∙s−1, the single plant integrity rate is 97.14% and the rate of injured potatoes is 0.67%. The machine can better meet the requirements of potato single plant harvesting and solve the problem of plant mixing. From the perspective of potato damage rate, potato breeding harvesters are also suitable for traditional potato harvesting.

The process of digging potatoes is characterized by high energy costs due to the interaction of the potato digger's plowshares with the tuber-bearing soil layer. The study aims to substantiate the parameters of potato digger's lattice plowshare. In the proposed potato digger, the plowshare is made latticed and equipped with oscillating rods. This potato digger has a mechanism for transmitting torque to oscillating rods. The experiments were carried out using a special laboratory-field installation. Various lattice plowshares were manufactured, and single-factor experiments were carried out. During the experiments, the degree of damage and loss of the tuber and the traction resistance potato digger were taken as evaluation criteria. The results of experimental studies to determine the parameters of plowshare are presented. It is established that the optimal design scheme for a potato digger consists of torque transmission mechanisms, lattice plowshares, and forcibly oscillating rods. As a result, theoretical studies, analytical dependencies, and mathematical models were obtained to determine the parameters of a lattice plowshare. Studies have established that to destroy the tuber formation to the required extent with minimal damage and loss of tuber, as well as energy costs, the width lattice plowshare should be 55 cm, the angle plowshare installation relative to the horizon is 22°, the length plowshare is 38 cm, and the width gap between the bars is 3 cm.

The article substantiates the need for this study, analyzes the advantages and disadvantages of various working bodies of loading devices, as well as the results of the analysis on the prospects of a finger-type separating working body for uniform loading of a pile of seeds into dryers. The factors influencing the working process of leveling the material and the methodology of experimental research are given. The maximum number of factors influencing the process under study has been determined, the most likely areas of their change have been selected and the conditions characterizing the process of leveling the pile of fodder crops by the loader have been selected. The schemes of dependence of the coefficient of uneven leveling of the pile on the feed rate of the material and the speed of rotation of the drum, the dependence of uneven leveling on the length of the finger and the gap between them, the dependence of uneven leveling on the diameter of the drum and the number of rakes and the dependence of uneven leveling on the angle of the fingers and the thickness of the layer of the pile, as well as the influence of kinematic, structural and technological parameters of the working body are presented on the quality of leveling the pile.
