Abstract
The utility model discloses a novel non-excavation drill bit, which comprises a drill bit main body, wherein more than two smashing rods are uniformly distributed on the periphery of the rear part of the drill bit main body, and smashing teeth are distributed on the smashing rods; this novel non-excavation drill bit can effectually smash the earth that drills out for earth mobility is better, changes the extraction and derives.
Description
Technical Field
The utility model relates to a novel non-excavation drill bit.
Background
The non-excavation is a new construction technology for laying, replacing and repairing various underground pipelines by utilizing various rock-soil drilling equipment and technical means under the condition of excavating on a very small part of the earth surface (generally referred to as small-area excavation at an inlet and an outlet) in the modes of guiding, directional drilling and the like, does not obstruct traffic, does not damage green lands and vegetation, does not influence the normal life and work order of shops, hospitals, schools and residents, solves the problem that the traditional excavation construction interferes with the life of the residents, and damages and adverse effects on the traffic, environment and the foundation of surrounding buildings, and therefore has higher social and economic effects. And need use the drill bit to carry out the reaming in the non-excavation, the drilling of current drill bit is crossed the back, and the earth that the rear left has the too big condition of volume, and the smooth and easy derivation of earth that will drill out of being not convenient for leads to inside operating pressure big.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a novel non-excavation drill bit, it can be effectual smashes drilling out earth for earth mobility is better, changes the extraction and derives.
The utility model discloses the above-mentioned technical problem that will solve realizes through following technical scheme:
the utility model provides a novel non-excavation drill bit, includes the drill bit main part, the rear periphery evenly distributed of drill bit main part have more than two to break the pole, the pole of smashing distribute and break the tooth.
Preferably, the other side surfaces of the breaking rod except the outer side surface are distributed with breaking teeth. This structural design scheme makes to smash the tooth and can effectually smash the earth at drill bit rear, also can not cause the destruction to the pore wall after the drilling simultaneously.
Preferably, the crushing teeth on the adjacent side surfaces of the crushing rod are distributed in a staggered manner. The structure scheme ensures that the breaking effect of the breaking tooth is more excellent.
Has the advantages that: adopt structure after, because the rear periphery of drill bit main part distributes and has the pole of smashing, and smash and distribute on the pole and smash the tooth, the utility model discloses when drilling, smash the tooth of smashing on the pole and can effectively drill out earth with drill bit main part rear and smash, guarantee that earth is even tiny for earth mobility is better, follows the pipeline extraction of drill bit main part rear portion connection more easily and derives.
Drawings
Fig. 1 is a side view of the novel trenchless drill of the present invention.
Fig. 2 is a rear view of the novel trenchless drill of the present invention.
Wherein: 1-drill bit main body, 2-breaking rod, 3-breaking tooth.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, which are not intended to limit the invention in any manner.
Example 1
The novel trenchless drill bit comprises a drill bit main body (1), wherein more than two smashing rods (2) are uniformly distributed on the periphery of the rear portion of the drill bit main body (1), the smashing teeth (3) are uniformly distributed on other side surfaces except the outer side surface of the smashing rods (2), and the smashing teeth (3) on the adjacent side surfaces of the smashing rods (2) are distributed in a staggered mode.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is familiar with the technical scope of the present invention, according to the technical solution and the utility model, the concept of the present invention is equivalent to replace or change, and all should be covered within the protection scope of the present invention.
Claims (3)
1. The utility model provides a novel non-excavation drill bit, its characterized in that, includes drill bit main part (1), the rear periphery evenly distributed of drill bit main part (1) have more than two to break pole (2), break pole (2) distribute and break tooth (3).
2. The new trenchless drill bit of claim 1 wherein the side of the breaking bar (2) other than the outer side is evenly distributed with breaking teeth (3).
