Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-4, the utility model discloses a dig drilling tool soon with arc tooth row, including barrel 1 and install the tooth row mechanism 2 in barrel 1 bottom, tooth row mechanism 2 includes tooth row spare 3 and tunnelling tooth 4, a plurality of installation breach 5 that are used for installing tunnelling tooth 4 are seted up to the longer one side of main part of tooth row spare 3, fixedly connected with tunnelling tooth 4 on the installation breach 5, the main part of tooth row spare 3 is the fan-shaped structure of circular arc, the sunken cambered surface opposite direction of at least two sets of tooth row spare 3 is fixed at the bottom soil material entrance 6 of barrel 1, the outside end face of tooth row spare 3 and the bottom edge fixed connection of barrel 1, the inboard terminal surface fixed connection of adjacent two sets of tooth row spare 3, be equipped with the middle part that the feed inlet connects barrel 1 between a plurality of tooth row spare 3.
Referring to fig. 5, the tooth row member 3 shown in fig. 6 is a tooth row of the prior art, the height of the tooth row in the middle is gradually reduced toward the outer side, the tooth row is a flat plate, the middle is firstly tunneled during tunneling, a broken soil layer moves toward the outer ring along the arrow direction shown in the figure, the broken soil layer just enters the opening of the cylinder body 1 during moving, so that the broken soil layer enters the cavity of the cylinder body 1, when the cavity of the cylinder body 1 is filled with the soil layer, the drilling tool is lifted out of the hole through the drill rod, the soil layer in the cavity of the cylinder body 1 is poured. However, the direction of the drilling tool which is arranged by the tooth row piece 3 and matched with the tunneling tooth 4 is along the outer ring, if the drilling tool meets clay or a strongly weathered stratum, the viscosity of a soil layer is large, the soil feeding speed is slow, and the soil layer is extruded on the hole wall when the cavity of the cylinder body 1 is not in time yet. Later, a method for scraping the hole wall is needed, and the construction efficiency is seriously influenced.
Through the drilling tool that above-mentioned technical scheme improved, the tooth row mechanism 2 of barrel 1 bottom installation, because the longer one side of the main part of tooth row spare 3 is the arc that has certain radian, form a fan-shaped structure, install and be fan-shaped the arranging equally in the tunnelling tooth 4 in the main part of tooth row spare 3, like individual tongs, like the arrow direction of fig. 1, the drilling tool advances soil along tunnelling tooth 4 to the centre in the soil layer, soil material gets into the middle part of barrel 1 at the bottom soil material entrance 6 of barrel 1, avoided advancing soil to a direction of barrel 1, barrel 1 advances soil more smoothly, there is better efficiency of construction in clay soil layer and strong morals and manners soil layer.
Fixedly connected with installation piece 7 between adjacent tooth row spare 3, the welding has the tunnelling tooth 4 that the tooth head opposite direction on installation piece 7, and the efficiency of dialling protruding to the cavity of barrel 1 is strengthened in 6 central authorities of the soil material entrance of barrel 1. The tooth head directions of the tunneling teeth 4 on the adjacent tooth row pieces 3 face different directions, and the rear part of the circular arc tunneling teeth 4 on the concave side is a soil inlet 6 at the bottom of the barrel body 1, so that a large amount of soil is pushed into the soil inlet 6 from the bottom of the barrel body 1, and the cavity of the barrel body 1 is filled rapidly.
The side opposite to the end face of the outer side of the gear row piece 3 is welded with one side of the connecting block 8, the other side of the connecting block 8 is fixedly connected with the edge of the bottom of the barrel 1, the connecting block 8 arranged at the position enables the gear row to rotate to the position of the connecting block 8, and the connecting block plays a role in limiting.
The middle part of barrel 1 and bottom soil material entrance 6 intercommunication have the cavity, have seted up through-hole 9 on the lateral wall of barrel 1, can follow through-hole 9 and discharge when the moisture in the soil material is more.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
