Description
Technical Field
The utility model relates to the field of horizontal drilling equipment, in particular to a horizontal guiding drill.
Background
The existing horizontal pilot drill which is most widely used at present mainly comprises an inclined palm face pilot bit and a roller bit. The inclined palm face guiding drill bit is mainly applied to soil layer construction and is provided with a guiding plate, the interface of the guiding plate is rectangular, and the guiding principle is as follows: 1) When the rotation is stopped and the drill bit is pushed, the inclined guide plate is contacted and extruded with the soil body to receive radial component force, so that the advancing direction is changed. 2) When the drill bit is rotated, the guide plate can generate surface crushing to the front soil body, the influence of radial force is eliminated, the guide plate linearly moves, the guide plate is a main stress part during excavation, the abrasion resistance of the edge part of the existing guide plate is poor, the edge of the guide plate is worn, the stress of the guide plate is changed, normal work cannot be performed, and the service life is short.
Disclosure of Invention

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a horizontal guiding drill, includes the guide bar, the slope is equipped with the deflector, characterized by can be dismantled to the guide bar: the edge of the end face of one side above the guide plate is provided with a carbide hard alloy layer in a surfacing mode, and carbide hard alloy blocks are orderly arranged on the side face of the guide plate.
The present utility model having the above-described features: the carbonized hard alloy has good wear resistance and corrosion resistance, and has high hardness, and the arrangement of the carbonized hard alloy layer and the carbonized hard alloy block on the edge of the guide plate increases the wear resistance of the edge of the guide plate and prolongs the service life of the device.
The utility model is further provided with the following steps: the carbide hard alloy block comprises an arc surface and a connecting surface, and the connecting surface is fixedly connected with the side surface of the guide plate.
The present utility model having the above-described features: the cambered surface is arranged more smoothly, so that soil materials can pass through conveniently, and the blocking is avoided.
The utility model is further provided with the following steps: the guide plate comprises a mounting part and a cooling part, wherein the mounting part is provided with a mounting hole, one end of the guide rod is provided with a mounting surface, the mounting surface is provided with a mounting hole matched with the mounting hole, and the mounting hole is connected with the mounting hole through a connecting piece.
The present utility model having the above-described features: the assembly holes and the mounting holes are connected through the connecting pieces, so that the guide plate can be detachably mounted.
The utility model is further provided with the following steps: the cooling part is provided with a cooling hole.
The present utility model having the above-described features: the guide plate can be cooled after the cooling holes are filled with water.
The beneficial effects of the utility model are as follows: through the arrangement of the carbonized hard alloy layer and the carbonized hard alloy block at the edge of the guide plate, the abrasion resistance of the edge of the guide plate is improved, and the service life of the device is prolonged.
The utility model is described in further detail below with reference to the drawings and examples.
