Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of guide drill, in particular to a guide plate and roller bit combined guide drill. BACKGROUND
[0002] The guide drilling construction method is widely applied to laying various underground pipelines, especially in the case of limited site conditions, can effectively avoid the construction difficulty and cost problem caused by excavating soil, and the soil-sand layer drilling guide drill is a construction method for drilling and pipeline laying by the directional drilling machine without excavating soil. Figure 1 As shown in the drawings, the original guide drill relies on the guide inclined plate drilling and guiding, can only be used in soft soil layer and soft sand layer, is easy to be damaged when meeting hard soil layer or relatively hard sand layer, and even cannot drill; when meeting the mixed soft and hard soil layer or mixed soft and hard sand layer, the drill bit specially used for drilling hard stratum needs to be replaced, so that the back-and-forth replacement of the drill bit affects the construction efficiency. UTILITY MODEL CONTENTS
[0003] To solve the above technical problems, the utility model provides a guide plate and roller bit combined guide drill suitable for different soil layers, improves the construction efficiency and practicality.
[0004] The guide plate and roller bit combined guide drill of the utility model, including drill bit main part, guide component and drilling component, the excavating end lower part of drill bit main part is equipped with guide component, and the upper part is equipped with drilling component, and the guide component and drilling component are combined and installed on the drill bit main part; through the combination of the guide component and drilling component, the guide drill can be used for drilling soft soil layer and soft sand layer, and also can be used for hard soil layer and relatively hard sand layer; especially suitable for the mixed soft and hard soil layer or mixed soft and hard sand layer, improves the construction efficiency and practicality.
[0005] Preferably, the guide component includes a guide inclined plate, which is installed at the bottom of the excavating end of the drill bit main part, and the end of the guide inclined plate away from the drill bit main part is inclined to the center line of the drill bit main part; the drill bit main part can be suitable for soft soil layer and soft sand layer through the guide inclined plate.
[0006] Preferably, the drilling component includes an alloy tooth roller, which is installed at the excavating end of the drill bit main part and is arranged opposite to the guide inclined plate; the alloy tooth roller can be suitable for hard soil layer and relatively hard sand layer, thereby being suitable for the mixed soft and hard soil layer or mixed soft and hard sand layer.
[0007] Preferably, an internal thread hole is formed at the end of the drill bit main part away from the guide inclined plate and the alloy tooth roller, and the thread is a standard thread connected with the drill rod; the guide drill is convenient to connect and install with the directional drilling machine and is convenient to use.
[0008] Compared with the prior art, the beneficial effects of the utility model are that: through the combination of the guide component and the drilling component, it can be used for drilling soft soil layer and soft sand layer, and also can be used for hard soil layer and hard sand layer, especially suitable for mixed soft and hard soil layer or mixed soft and hard sand layer, improves the construction efficiency and improves the practicability.
