Problems solved by technology
[0002] In the process of seismic exploration, forming holes in thick soil is an important link. It needs to be excavated several meters to tens of meters deep to place explosives to achieve good seismic effects. In the past, Luoyang shovels were commonly used to form holes. It usually takes a long time to form holes more than ten meters deep, which is laborious and expensive. Mining efficiency is low

Embodiment Construction
[0021] Below in conjunction with embodiment, the present invention is described in further detail:
[0022] A ground excavation drilling device, such as Figure 1-3 As shown, it includes a drilling unit and a transport unit disposed above the drilling unit. like figure 1 As shown, the drilling unit includes a drill bit 14 fixed on the end of the drill pipe 13 and a drive motor 10 connected with the drill pipe 13. The drive motor 10 with waterproof protection rotates to drive the drill pipe 13 to rotate at a high speed, thereby driving the drill The drill bit 14 below the rod 13 rotates to achieve drilling. The drill bit 14 is a diamond triangular bit, the diamond has high hardness, and the triangular-shaped configuration makes it easier to drill. The drilled broken soil, mud, etc. are brought out of the wellbore with the transport unit to facilitate deeper drilling.
[0023] The transport unit includes a conveyor belt 1 disposed above the drive motor 10 and one-way blades ...

The invention discloses a ground excavation well drilling device, and belongs to the field of seismic exploration. The ground excavation well drilling device comprises a well drilling unit and a transportation unit arranged above the well drilling unit. The well drilling unit comprises a drill bit fixedly arranged on the end part of a drill rod and a driving motor connected with the drill rod. The conveying unit comprises a conveying belt arranged above the driving motor and a one-way blade fixedly arranged on the conveying belt, and the conveying belt conveys crushed soil turned up by the drill bit below a double-layer shaft to a shaft opening of the double-layer shaft to throw out the crushed soil in the double-layer shaft. The ground excavation well drilling device is novel in design, reasonable in structure and capable of achieving rapid excavation, the hole forming speed is high, the field construction efficiency is greatly improved, the double-layer shaft and the conveying belt with the one-way blade can be lengthened according to needs, excavation is smoothly achieved, if hard and difficult-to-crush objects exist in the well excavation process, the bevel shaft can be connected, the drilling direction is slightly changed, and the construction requirement is met.
Description
technical field [0001] The invention relates to the field of seismic exploration, in particular to a ground excavation drilling device. Background technique [0002] In the process of seismic exploration, the formation of holes in thick soil is an important part. It is necessary to excavate a few meters to tens of meters deep to place explosives for the seismic effect. In the past, Luoyang shovels were commonly used for excavation, and it generally took a long time to form holes more than ten meters deep, which was laborious and difficult. Mining efficiency is low. [0003] In order to drive quickly and efficiently, it is necessary to develop an easy-to-use and fast excavation drilling equipment. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a ground excavation drilling device, which greatly shortens the hole forming time, has fast excavation speed, and has high explosive placement efficiency. [0005] For sol...
