Embodiment 1

[0012] Embodiment 1, the present invention comprises drill bit 1, drill rod 2, conical baffle plate 3, drill bit seat 4, air channel 7, wherein, conical baffle plate 3 conical head is arranged on the lower end of drill bit seat 4 downwards, and drill bit seat 4 is provided with At the bottom of the drill rod 2, the drill rod 2 passes through the center of the tapered baffle plate 3 and the drill seat 4, the drill bit 1 is arranged at the bottom of the drill rod 2, and the inside of the drill bit 1 and the drill rod 2 is a hollow air passage 7. refer to figure 1 .

Embodiment 2

[0013] Embodiment 2, the top of the drill pipe 2 is connected to the exhaust fan or other devices, the air passage 7 runs through the entire drill bit 1 and the drill pipe 2, and the air is ejected from the air passage to blow the drill cuttings and dust generated by drilling to the outside of the hole, and at the same time It can also cool down the drill bit. refer to figure 1 , all the other are with embodiment 1.

Embodiment 3

[0014] Embodiment 3, the drill seat 4 is fixed on the guide mechanism 5 by using the connecting angle code 8, and the guide mechanism 5 is arranged on the mast 6, so that the direction and angle of the drill bit can be adjusted through the guide mechanism 5. refer to figure 1 , and the rest are the same as the above-mentioned embodiment.

Abstract

The invention discloses a deslagging device, which belongs to a deslagging device of a cut drilling machine and mainly solves the technical problems of high dust raising amount, high drilling cutting temperature and the like easily caused by the conventional air deslagging device in a drilling construction place. According to the key points of the technical scheme, the deslagging device comprises a drill bit (1), a drill rod (2), a conical baffle plate (3), a drill bit seat (4) and the like, wherein the conical baffle plate (3) is arranged at the lower end of the drill bit seat (4); the drill rod (2) penetrates through the conical baffle plate (3) and the drill bit seat (4); the drill bit (1) is arranged at the bottom of the drill rod (2); the drill rod (2) is connected with an exhaust blower or other devices, and air is exhausted from a hollow air channel (7) of the drill rod (2); and the direction or angle of the drill bit is adjusted by a guiding mechanism (5) arranged on a mast (6). The deslagging device is mainly used for finishing deslagging operation, controlling a deslagging dust raising condition and reducing the temperature of the drill bit during drilling operation of the cut drilling machine, has a simple structure and is convenient to use and maintain.

Description

technical field [0001] The invention relates to a slag discharge device of a cutting drilling machine, in particular to a slag discharge device. Background technique [0002] At present, the air exhaust device adopted by the drilling rig is likely to cause a lot of dust in the drilling construction site, which poses a hazard to the health of the construction workers. The drill bit is high in temperature, easy to damage, complex in structure, and inconvenient to use and maintain. Contents of the invention [0003] The purpose of the present invention is to provide a slag discharge device that can overcome technical problems such as large dust in the drilling construction site, high temperature of the drill bit, complex structure, and inconvenient use and maintenance of the air discharge device adopted by the current drilling rig. [0004] The technical solution adopted by the present invention to solve its technical problems is: it is made up of drill bit 1, drill rod 2, co...
