Description

Geological drill rod
Technical Field
The invention relates to a geological drilling tool, in particular to a geological drill rod.
Background
The drilling rod that generally uses at present is cylinder type drilling rod, and cylinder type drilling rod has with low costs, the advantage of easy processing, nevertheless at the in-process of rock debris of arranging, need rely on drill bit department spun cooling water to take away rock powder from the drilling, because the complicated change of drilling depth and geological structure, when the hole inner wall because geological structure is soft the local collapse that appears for a large amount of rocks and earth wrap the drilling rod, rock powder is piled up, is blockked up in the drilling, and the powder can not discharged fast, causes and embraces the brill accident.
In consideration of chip removal, an auger stem is provided, rock debris can be conveyed backwards and discharged gradually by a helical blade on the auger stem, cooling water enters from the center of the auger stem, but the helical blade is in contact with rock, the temperature of the helical blade is high, so that the cooling effect of the cooling water at the center of the auger stem on the helical blade is poor, the strength of the auger stem is reduced, and the service life of the auger stem is short.
Disclosure of Invention
In order to overcome the defects, the invention provides a geological drill rod with good chip removal and cooling effects, which comprises a drill rod body 1, wherein the bottom of the drill rod body 1 is provided with a hexagonal joint 2, the top of the drill rod body is provided with a hexagonal groove 3 corresponding to the hexagonal joint 2, the outer surface of the drill rod body 1 is also provided with two spiral lugs 4, a spiral chip removal groove 5 is formed between the two spiral lugs 4, and a spiral water channel 6 is arranged in each spiral lug 4.
According to the geological drill rod, the lower end opening of each spiral water channel 6 is provided with a flow guide opening 7, the flow guide openings 7 are smaller than the openings of the spiral water channels 6 and can be respectively and correspondingly inserted into the upper end openings of the two spiral water channels of the next geological drill rod, and after the flow guide openings are inserted into the spiral water channels, water can be prevented from flowing out of the connection position of the two drill rods, and the two connected drill rods can be clamped.
The invention relates to a geological drill rod, which is characterized in that a hexagonal joint 2, a spiral lug 4 and a drill rod body 1 are of an integrated structure.
According to the geological drill rod, the lengths of the hexagonal joint 2 and the hexagonal groove 3 are equal, at least one lower thread mounting hole 8 is formed in the hexagonal joint 2, the number of upper thread mounting holes 9 which is equal to that of the lower thread mounting holes 8 and corresponds to that of the lower thread mounting holes 8 in one-to-one mode are formed in the hexagonal groove 3, when the hexagonal joint is inserted into the hexagonal groove of the next geological drill rod, the upper thread mounting holes are matched with the lower thread mounting holes, and the two address drill rods can be connected and mounted through bolts.
According to the geological drill rod, the axes of the upper thread mounting hole and the lower thread mounting hole are perpendicular to the axis of the drill rod body 1.
The invention has the beneficial effects that:
the rock debris can be conveyed and discharged backwards step by the debris grooves, cooling water is introduced from the spiral water channel, the spiral lug can be effectively cooled, and the service life of the drill rod is greatly prolonged.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a schematic top perspective view of the present invention;
FIG. 2 is a schematic bottom perspective view of the present invention;
FIG. 3 is a schematic illustration of two geological drilling rods after connection;
fig. 4 is a cross-sectional view of the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
The geological drill rod shown in fig. 1-4 comprises a drill rod body 1, wherein a hexagonal joint 2 is arranged at the bottom of the drill rod body 1, a hexagonal groove 3 corresponding to the hexagonal joint 2 is arranged at the top of the drill rod body 1, two spiral protrusions 4 are further arranged on the outer surface of the drill rod body 1, spiral chip discharge grooves 5 are formed between the two spiral protrusions 4, and rock chips can be conveyed backwards and discharged gradually. A spiral water channel 6 is arranged in each spiral lug 4, cooling water is introduced from the spiral water channel, the spiral lugs can be effectively cooled, and the service life of the drill rod is greatly prolonged. The lower end opening part of each spiral water channel 6 is provided with a flow guide opening 7, the flow guide opening 7 is smaller than the opening of the spiral water channel 6 and can be respectively and correspondingly inserted into the upper end openings of the two spiral water channels of the next geological drill rod, and after the flow guide openings are inserted into the spiral water channels, water can be prevented from flowing out of the joint of the two drill rods, and the two connected drill rods can be clamped. The hexagonal joint 2, the spiral lug 4 and the drill rod body 1 are of an integral structure. The length of the hexagonal joint 2 is equal to that of the hexagonal groove 3, at least one lower thread mounting hole 8 is formed in the hexagonal joint 2, upper thread mounting holes 9 which are equal to the lower thread mounting holes 8 in number and correspond to the lower thread mounting holes 8 in one-to-one mode are formed in the hexagonal groove 3, and the axes of the upper thread mounting holes and the lower thread mounting holes are perpendicular to the axis of the drill rod body 1.
During installation, the hexagonal joint of the previous geological drill rod is inserted into the hexagonal groove of the next geological drill rod, the two flow guide ports of the previous geological drill rod are inserted into the upper end opening of the spiral water channel of the next geological drill rod, the upper thread mounting hole and the lower thread mounting hole at the joint of the two geological drill rods are matched, and the two address drill rods can be connected and installed through bolts, so that the structure is simple, and the installation is convenient.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
