Description
Technical Field
The utility model relates to a drilling machine, especially drilling tool of drilling machine belongs to underground foundation construction machinery technical field.
Background
The existing multi-shaft underground diaphragm wall drilling machine, single-shaft drilling machine and other foundation treatment drilling machines have the advantages that generally only one channel is arranged on each drill rod for conveying cement slurry, a cement slurry nozzle is generally positioned at the bottom of a drilling tool, when the drilling tool is drilled to a set depth, the drilling machine rotates the drilling tool while lifting upwards, and the cement slurry is sprayed, but the cement slurry is not uniformly mixed with soil due to the fact that the cement slurry nozzle is positioned at the bottom of the drilling tool if the up-and-down reciprocating stirring times are not enough, and construction quality is affected. But if the up-down reciprocating stirring frequency is ensured, the construction quality is ensured, but the construction efficiency is influenced. Therefore, it is necessary to research and develop a drilling tool which can ensure the stirring frequency of cement slurry and soil, ensure the uniform mixing of the cement slurry and the soil, ensure the construction quality and improve the construction efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the not enough that exists among the prior art, invented a side spout valve plate drilling tool, this drilling tool is equipped with the whitewashing mouth in the top of stirring wing, and the outside of whitewashing mouth is equipped with the valve plate, and when the drilling tool up-rotated lifting, the whitewashing mouth was opened, and the thick liquid is spout from this spout, and the spun thick liquid is stirred by this stirring wing, makes the homogeneous mixing between thick liquid and the soil to construction quality has been ensured when improving the efficiency of construction.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a side-spraying valve plate drilling tool comprises a circular drill rod 1, a valve plate 2 and a stirring wing 3, wherein a valve plate frame 13 is arranged on the outer circumference of the drill rod 1, the inner side surface of the valve plate frame 13 is arc-shaped and is fixedly connected with the circular drill rod 1 in a concentric mode, a slurry spraying port 12 is arranged on the outer side surface of the drill rod 1 and above the stirring wing 3, the slurry spraying port 12 is arranged between an upper guide groove 131 and a lower guide groove 132 of the valve plate frame 13, the slurry spraying port 12 is communicated with a slurry pipe 11 in the drill rod 1, and the valve plate 2 is arranged in the upper guide groove 131 and the lower guide groove 132 of.
In a preferred embodiment, the upper and lower guide grooves 131 and 132 of the valve plate frame 13 have a rectangular cross section.
As another preferred embodiment, the valve plate 2 includes a valve plate body 21 and a vertical plate 22, and the vertical plate 22 is perpendicular to the tangential direction of the outer circumferential surface of the valve plate body 21.
As another preferred embodiment, the valve plate 2 further comprises a rib plate 23, and the rib plate 23 is arranged perpendicular to the vertical plate 22.

Detailed Description
The side spray valve plate drilling tool shown in the attached drawing comprises a circular drill rod 1, a valve plate 2 and a stirring wing 3, wherein a slurry pipe 11 is arranged inside the circular drill rod 1, a slurry spraying port 12 is formed in the outer side surface of the circular drill rod 1, which is positioned above the stirring wing 3, a valve plate frame 13 is arranged on the outer circumference of the circular drill rod 1, the inner side surface of the valve plate frame 13 is arc-shaped and is concentrically arranged with the circular drill rod 1, the sections of an upper guide groove 131 and a lower guide groove 132 of the valve plate frame 13 are rectangular, the slurry spraying port 12 is positioned between the upper guide groove 131 and the lower guide groove 132 of the valve plate frame 13, and the slurry spraying port 12 is further communicated with the slurry pipe. The valve plate 2 comprises a valve plate body 21, a vertical plate 22, a rib plate 23 and a barrier strip 24, wherein the vertical plate 22 is perpendicular to the tangential direction of the outer circumferential surface of the valve plate body 21, the rib plate 23 is perpendicular to the vertical plate 22, and the barrier strip 24 is positioned at the end parts of an upper guide groove 131 and a lower guide groove 132; the valve plate 2 is arranged in the upper guide groove 131 and the lower guide groove 132 of the valve plate frame 13; the stirring wing 3 is fixedly connected with the drill rod 1.
During construction, as the drilling tool rotates downwards in the forward direction to form a hole, at the moment, the valve plate 2 is stopped by a mixture of cement slurry and soil after stirring, so that the valve plate 2 rotates along the upper guide groove 131 and the lower guide groove 132, and the grout spraying port 12 is closed when passing through the grout spraying port 12; when the drilling machine rotates reversely and lifts up, the valve plate 2 rotates along the upper guide groove 131 and the lower guide groove 132 due to the blocking of the mixture of the cement grout and the soil after being stirred, the grout spraying port 12 is changed from a closed state to an open state when passing through the grout spraying port 12, so that the cement grout is sprayed out from the grout spraying port 12, the sprayed cement grout is stirred by the stirring wings 3, the cement grout is uniformly mixed with the soil, and the mixing effect between the cement grout and the soil can be greatly improved. Because the stirring is not required to be carried out repeatedly up and down, the construction quality is ensured, and the construction efficiency is improved.
The cement slurry of the utility model belongs to a curing agent, and the curing agent can be other liquid or solid curing substances.
