Description

Reaming bit structure of drilling machine

The invention relates to a drill bit of an excavator, in particular to a drill bit structure of the excavator capable of reaming and cutting without changing the drill bit.

The drilling machine is a large-scale machine tool used for drilling shafts or tunnels. The drilling work of the drilling machine is usually a two-stage operation. After the first drilling, the expansion machine will be replaced. However, when the drill bit is pulled out to replace the reaming bit, the wall of the drilled hole will collapse due to the soft soil, resulting in the failure of the drilling work. Moreover, the action of replacing the drill bit between the secondary drilling and cutting is time-consuming and laborious, so it is quite time-consuming in engineering construction.

From the above, there are still quite a lot of problems when the drilling machine is drilling. Therefore, in view of the above problems, the inventor of this case is eager to improve and innovate. After years of painstaking research, he finally successfully developed and completed this drill. The reaming drill bit structure of the excavator.

In order to solve the problems of the prior art, an object of the present invention is to provide a reaming drill bit structure of an excavator capable of reaming and cutting operations without changing the drill bit.

In order to solve the problems of the prior art, another object of the present invention is to provide a reaming drill bit structure of an excavator that utilizes a control panel to adjust the flank bit penetration and retraction of the side edge of the drill bit.

In order to achieve the above object, the reaming drill structure of the drilling machine provided by the present invention mainly includes a drill main body, a control panel and a plurality of flank drill bits, one side of the drill main body is provided with multiple grinding machines, and the drill main body is oppositely provided with The other side of these grinders is provided with a plurality of grooves extending from the position near the center of the drill body to the periphery.

The flank drill bits are arranged respectively in the grooves. The flank drill bits all include a guide seat and a grinding drill bit. A receiving groove is provided at the intersection of the guide bases, and a guide groove is provided on the other surface of the guide seats opposite to the groove-through direction, and the grinding drill bits are respectively set in the receiving grooves, and the grinding drill bits One side outer edge of the drill bit passes out of the accommodating grooves.

The control panel is located on one side of the drill main body provided with grooves. One surface of the control panel is provided with a plurality of guide rails respectively docked with the guide grooves, and the guide rails are located near the center of the control panel to The arc curve extends toward the periphery of the control panel.

Wherein, the through grooves are equidistantly recessed and distributed on one surface of the drill body.

The reaming drill bit structure of the drilling machine provided by the present invention mainly uses the grinder installed on the drill bit main body to carry out the drilling and cutting action while the drill bit main body is being driven to drill, and when the reaming drill is required When cutting, it is not necessary to pull out the main body of the drill bit. It is only necessary to rotate the control panel so that the guide seat is pushed by the guide rail of the control panel and pushed out along the groove to the periphery of the drill bit body. The grinding drill bit is exposed on the outer edge of the drill bit body, so as to carry out the action of reaming and cutting through the grinding drill bit. Therefore, compared with the conventional drilling machine, which needs to perform two-stage drilling operations, the present invention uses the flank drill The setting of the head, so the reaming drilling and cutting action can be performed without replacing the drill bit, thereby increasing the drilling efficiency and avoiding the collapse of the hole wall when the drill bit is replaced.
