CUTTING-LOADING MACHINE Russian patent published in 2020 - IPC E21C35/24 

FIELD: mining.

SUBSTANCE: invention relates to cutting-loading machines. Cutting-loading machine comprises running gear, lower baffle device, at least one actuator including two-rotor module, control means of said actuator, said two-rotor module is provided with at least one handle with a cutting device. Said cutting device has a cutting radius R_C and the rotation axis of said cutting device by said handle makes portable circular rotation with a radius R_P. Frequency of rotation of said cutting device is determined by formula: where coefficient K is ratio of cutting radius R_C to radius R_P, m; Vcut is cutting velocity of cutting device, m/s; Hwork is working height, m. Value of coefficient K is not less than 0.35, and said control means is configured to adjust the cutting speed n_D of the cutting device and/or the portable rotational frequency n_p of the handle such that the ratio n_D to n_p is in range of 7 to 12.

EFFECT: higher efficiency at minimum power inputs, as well as formation of optimum shape of working.
