The stepped holes are opposite to the fastening screw holes in position. The tooth crown blade is fastened onto the drill rod through the compression screws. The connection strength of the tooth crown blade and a cutter body is improved through in-groove locking.

Inner core mounting structure of roller bristle sleeve machine
The invention discloses an inner core mounting structure of a roller bristle sleeve machine. The inner core mounting structure is characterized in that N supporting shafts are uniformly arranged on the circumference of a first rotary disc; a discharging mechanism conveys bristle sleeve rods to a first station supporting shaft of the first rotary disc; a first cutter cuts the bristle sleeve rods in a fixed length manner; a disc replacing device horizontally pushes bristle sleeves from the supporting shafts into sleeves of a second rotary disc; the second rotary disc is provided with a clamping station and an off-line station, and the second rotary disc is rotated to enable the bristle sleeves to complete clamping of inner cores; and a positioning plate is arranged on the front side of the clamping station, a vibration disc, a first core clamping groove and a second core clamping groove are arranged on the rear side of the clamping station, the first core clamping groove is connected with an inner core output rail of the vibration disc, displacement mechanisms are arranged beside the first core clamping groove and at the rear end of the second core clamping groove, the displacement mechanisms are used for enabling the inner cores to enter the second core clamping groove from the first core clamping groove and to be inserted into the bristle sleeves from the second core clamping groove, and the positioning plate is used for preventing the bristle sleeve from falling off from a cylinder sleeve. The structure is simple and effective and has low cost and compact and reasonable equipment layout.
