Multifunctional automatic protection alternating-current brushless grooving machine

Abstract

The invention provides a multifunctional automatic protection alternating-current brushless grooving machine which comprises a machine head, a shell, a handle and a protective cover, a rotating shaftis arranged in the machine head, a cutting blade is arranged at the lower end of the rotating shaft, the protective cover is connected with the rotating shaft through a bearing and half surrounds thecutting blade, and the multifunctional automatic protection alternating-current brushless grooving machine further comprises an auxiliary protective cover. The movable end of the auxiliary protectivecover is inserted into the side edge of the protective cover and hinged to the protective cover to achieve rotating connection, and the two sides of the free end of the auxiliary protective cover areconnected with the protective cover through elastic parts to achieve automatic opening and closing of the auxiliary protective cover. According to the multifunctional automatic protection alternating-current brushless grooving machine, grooving can be effectively conducted on the two walls of the vertical plane. Meanwhile, continuous grooving can be conducted on uneven occasions or occasions withobstacles such as cement blocks, protection is provided in the whole process, more importantly, the grooving process is smooth, a cutting blade does not need to be pulled out, and therefore the grooving difficulty and burden are reduced.

Description

technical field [0001] The invention relates to the technical field of slotting machines, in particular to a multifunctional automatic protection AC brushless slotting machine. Background technique [0002] The traditional slotting machine is mainly used for asphalt, cement pavement pavement repair, drainage pipes, gas pipes, electric wire pipes and optical cable pipes. The road surface is quickly cut into uniform grooves by a rotary saw to form a new joint surface. Optimize the contact level between the filling material and the slot, and strengthen the tightness of the bonding between the filling material and the side wall of the slot. With the development of society and the advancement of science and technology, people have higher and higher requirements for office conditions and homes. In the process of place and home interior decoration, strong and weak current wiring, water and gas pipeline laying are required; at present, the most effective way for strong and weak curr...

Problems solved by technology

[0003] During the grooving process, it is often encountered that the two walls of the vertical surface are grooving, and in the case of unevenness or obstacles such as cement blocks, etc., the continuous grooving cannot be done, so it is necessary to stop and pull the cutting blade out of the cutting groove. Use your hands to open the auxiliary cover before slotting. This will not only increase the burden of slotting, but also easily cause injury to the staff and form a safety hazard.
