Embodiment Construction

[0013] Accompanying drawing is a kind of concrete embodiment of the present invention, and this embodiment dial pin 1 is fixed on the middle part of drill shaft 4, drill bit 5 is arranged at the lower end of drill shaft, two bushings up and down are arranged outside the drill shaft, and upper bushing 2 is fixed on the connection. On the plate 6, the lower bushing 3 is supported on the two ends of the connecting plate 6 by two braces, and the connecting plate is fixed on the beam 12 by screws. Shift fork 7 is fixed on the support 13, and support 13 is fixed on the right saw tool holder 11.

[0014] When the groove sawing machine works, the saw blade frame 11 reciprocates left and right, and the bracket 13 fixed on the saw blade frame 11 and the shift fork 7 also reciprocate left and right. During the left and right movement of the shift fork 7, the dial needle 1 swings left and right, so the drill Axle 4 and drill bit 5 also swing from side to side, and the formation is drilled...

Abstract

The invention discloses an oscillating drill for a trench saw. A poking pin is fixed in the middle of a drill spindle; the lower end of the drill spindle is provided with a drill bit; an upper spindle sleeve and a lower spindle sleeve are arranged outside the drill spindle; the upper spindle sleeve is fixed to a connecting plate; the lower spindle sleeve is supported to two ends of the connecting plate through two diagonal bracings; the connecting plate is fixed to a crossbeam through a screw; a poking fork is fixed to a bracket; and the bracket is fixed to a right saw blade frame. The oscillating drill is a drill special for an underground impervious wall trench saw.

Description

1. Technical field [0001] The invention relates to a grooving machine drill, in particular to an oscillating drill for an underground anti-seepage wall sawing a grooving machine. 2. Background technology [0002] The working principle of the groove saw machine is: the submersible motor drives the crank to rotate, the crank passes through the connecting rod, and the rocker arm pushes the left and right saw blades to face each other, synchronously and reciprocatingly, cutting the stratum into grooves. [0003] During the grooving process of the grooving machine, if the force on the two saw blades is uneven, it will cause the grooving machine to vibrate or shift. , to prevent the grooving machine from shaking or deflecting. [0004] At present, the grooving machine drills are all non-rotating. If there is a hard soil layer, the drills are difficult or impossible to excavate because they cannot rotate. 3. Contents of the invention [0005] In order to make up for the deficie...
