为了改善焊工的劳动条件,我們研究了这部半自动的土切割机,可使焊工切割时由蹲着工作改为坐着操作。这部切割机可进行直线与圓弧切割。它的特点是結构簡单,制造方便,同时操作方便,又可提高功效。具体构造如图所示。操作时,进行直线切割,只需把軌道放好(与切割线平行),把小车上的卡子卡好,以防轉动臂轉动。将切割器对准线后,开始切割、工人可坐軌道的一端摇动 In order to improve the working conditions of welders, we studied the semi-automatic earth cutting machine, allowing the welder to switch from squat work to sitting operation. This cutting machine can be straight and circular cutting. It is characterized by simple structure, easy manufacture, and easy operation, but also improve efficiency. Specific structure as shown. Operation, the straight line cutting, simply put the track (parallel to the cutting line), the car stuck on the card, to prevent rotation arm rotation. After aligning the cutter, start cutting and the worker can rock at one end of the track
