ABSTRACT:
The drilling apparatus according to the invention contains a body (1) and rock-destroying organs (3) of the cutting and shearing type that are attached to the matrix (2) of the body. The body (1) is provided with a turbulence chamber (4) with tangentially aligned entry channels (5) and a central outlet channel (6). Tangentially arranged outlet channels (9) are designed in the lower part of the body (1). The part of the matrix (2) closest to the body (1) is designed in the form of a hollow truncated cone with its top surface (12) turned toward the body (1). The sphere is designed with a changing slope of the generatrices (10) of the conical surface and with the bottom surface (11) and the top surface (12) designed according to the Archimedean spiral. On the lateral surface of the matrix (2) there are continuous radial grooves (13) that are connected to the outlet channels (9) by a cavity (14) designed in the body (1).
