Embodiment Construction

[0026] see Figure 1-2 , shows the progressive drilling multi-head cutting drilling device of the present invention.

[0027] The progressive drilling multi-head cutting drilling device includes a cylindrical body. In order to facilitate loading and unloading and reduce costs, the cylindrical body can adopt a split structure, such as figure 1 As shown, the cylindrical body 1 at least includes an outer shell 101, a front cover 102 and a rear cover 108, the outer shell 101 is located in the middle, and the front cover 102 and the rear cover 108 are respectively provided at both ends to form a hollow structural strip Cylindrical structure.

[0028] The front end of the cylindrical body is provided with a drill bit 105 for drilling, the rear end of the cylindrical body is provided with an adapter rod 106, and the rear end of the adapter rod 106 is provided with an embedding groove 110. Groove 110 can be embedded by a driving rod, and the front end of described driving rod is pro...

Abstract

The invention discloses a progressive drilling-in type multi-drill-bit cutting and drilling device which comprises a cylindrical body. The front end of the cylindrical body is provided with drill bits for drilling. An adaptive rod is arranged at the rear end of the cylindrical body. An embedded groove is formed in the rear end of the adaptive rod. A transmission rod is arranged between the drill bits and the adaptive rod. The rear end of the transmission rod abuts against the front end of the adaptive rod. The outer side of the connection portion between the transmission rod and the adaptive rod is provided with a connecting sleeve. A spline groove is formed in the inner wall of the connecting sleeve. The outer surface of the rear end of the transmission rod and the outer surface of the front end of the adaptive rod are provided with splines embedded into the spline groove in a matched mode. The rear ends of the drill bits are provided with a connecting rod connected to the front end of the transmission rod. The rear end of the connecting rod is connected to the transmission rod in a concave-convex embedded mode. Accordingly, the progressive drilling-in type multi-drill-bit cutting and drilling device is simple in structure, convenient to match and operate, better in overall strength and better in guide effect during drilling-in, and ensures drilling-in precision.

Description

technical field [0001] The invention relates to a device for drilling into the ground, in particular to a progressive drilling multi-head cutting drilling device which can effectively improve drilling efficiency. Background technique [0002] In order to better detect, excavate, and extract resources from the underground layer, it is necessary to perform an effective and fast drilling operation on the underground layer, that is, to drill the underground layer through a drill bit to form a borehole of a predetermined depth in the underground layer. [0003] In order to achieve drilling, a drill bit that can cut underground rocks, soil, gravel, etc., a driving device that drives the drill bit to rotate, and a guide rod that guides the drill bit to drill are usually used to form a downward drill. Drilling device. [0004] However, as the situation in the underground layer becomes more and more complex, the requirements for drilling are higher, and the existing drilling equipme...
