The specific embodiment
It comprises head box 1, motor 11, main shaft 2, is located at the spindle drive and the tape handler of head box 1 top, cylinder 5 is installed in the head box 1, the piston rod 5a of cylinder is fixedlyed connected with the collar bush 3 that is installed in main shaft 2 lower ends by the gusset piece 4 of being located at head box 1 below, also be provided with depthkeeping bar 16 on the head box 1, depthkeeping bar 16 is installed on the gusset piece 4, depthkeeping bar 16 is provided with up stroke briquetting 18 and down stroke briquetting 17, and described up stroke briquetting 18 and down stroke briquetting 17 all are fastened on the depthkeeping bar 16; Also be provided with upper stroke switch 19 and lower stroke switch 15 on the head box 1; Described automatic feeder also is provided with one-way throttle valve 14 and two the adjustable speed regulators 6 that are installed on the head box 1.
The mechanism that controls feed, withdrawing stroke in the automatic feeder of the present utility model comprises upper stroke switch 19, lower stroke switch 15, up stroke briquetting 18, down stroke briquetting 17 and depthkeeping bar 16.When the up stroke briquetting 18 on the depthkeeping bar 16 was pressed onto upper stroke switch 19, two cylinders 5 stopped to move back and draw, and this moment, main shaft 2 was in the original position of stroke; When the down stroke briquetting 17 on the depthkeeping bar 16 was pressed onto lower stroke switch 15, two cylinders 5 stopped to advance, and this moment, main shaft 2 was in the final position of stroke.Down stroke briquetting 17 is fixed on the depthkeeping bar 16 by holding screw, by regulating the position of down stroke briquetting 17 on depthkeeping bar 16, the stroke of control main shaft 2, thereby the control of realization drilling depth.
