我站测沙装置主要是如何控制采样器击锤的问题。在这方面,我们是利用晶体管开关电路(见图一)来控制击锤下击,击锤控制器(见图二)系由晶体开关控制、动力玩具马达、减速齿轮组、脱锤器等组成。如图三,如果在室内以3伏的直流电正极接循环索,负极接主索,晶体管开关电路GB_1导通时,GB_2随即导通,小马达便工作, My station sand measurement device is how to control the sampler hammer problem. In this regard, we use the transistor switch circuit (see Figure I) to control the hammer hit, the hammer controller (see Figure II) by the crystal switch control, power toy motor, reduction gear set, hammer and other components . As shown in Figure 3, if the room with a positive DC 3V then loop cable, the negative then the main cable, the transistor switch circuit GB_1 conduction, GB_2 then turn on the small motor will work,
