Abstract: The article is aimed at substantiating the need for the use of executive bodies of a helical geokhod. The relevance of the study is noted, which consists in ensuring the lowest values of cutting and feeding forces for a more energy-efficient destruction process. The features of the geokhod's executive body are given. Using the example of a knife executive body of a geokhod with various cutting edge shapes, a study was conducted on the effect of the geolicoid executive body of a geokhod on its power parameters. A mathematical model of the interaction of the knife executive body of a geokhod with various cutting edge shapes with the face rock is presented. The initial data for the study has been accepted. According to the results of the work, the helicoid nature of the executive body reduces the force of the geokhod feed to the face by 25% with a straight cutting edge, by 26% with an inclined one, by 45% with a convex one and 35% with a semi-convex one. Cutting forces are reduced by 12%, 19%, 17% and 15%, respectively. The torque on the actuator will decrease by 11% for straight, by 9% for inclined, by 15% for convex and 10% for semi-convex cutting edges. The conducted research confirms the need to create executive bodies of the geokhod of a helical shape, based not only on the features of the geokhod, but also on the influence of the helical nature of the executive body of the geokhod on its power parameters. The greatest influence of helicoidityis observed on the knife-like executive organs of the geokhod with an inclined shape of the cutting edge.
