流动排灌站在移动前,需要机手下水或提出吸水管将其中的存水放掉,这样既不方便,劳动强度又大,贫下中农迫切要求解决这个问题。广东顺德农机修配厂根据贫下中农的要求,在底阀上加一杠杆(见图),很好地解决了这个问题。对原有底阀不需要作任何改动,只需加个如图所示的杠杆,杠杆一端铰接在角钢上,该角钢固定在法兰盘螺钉上,杠杆另一端栓一条绳子,在排灌机组移动前,提拉绳子通过杠杆突起部分顶开底阀,放掉吸水管中存水,然后提出吸水管,搬动排灌机组。这种机构通过几年的实践证明,安全可靠,使用
Before the mobile irrigation and drainage station is moving, it is necessary for the pilot to launch or absorb the water to release the water therein, which is inconvenient and labor-intensive. The poor middle peasants are urgently required to solve this problem. Shunde, Shandong Agricultural Machinery Plant in accordance with the requirements of poor middle peasants at the end of the valve plus a lever (see Figure), a very good solution to this problem. The original valve at the end does not need to make any changes, just add a lever as shown, one end of the lever hinged on the angle, the angle plate is fixed on the flange screw, the lever at the other end of a rope tied to move in the irrigation and drainage units Before pulling the rope through the protruding part of the lever to open the bottom valve, let go of the suction pipe to store water, and then put forward the suction pipe to move the drainage and irrigation unit. This body proved by several years of practice, safe and reliable, use
