| 首先呢是草帘厚薄不一致造成的大棚卷帘机跑偏。有些菜农每年都要进行草帘的更换，淘汰一部分破旧的草帘，有的菜农将新旧草帘混在一起使用，新的草帘往往紧实较厚，旧草帘相对宽松较薄，若搭配不合理，出现一侧草帘较厚一侧草帘较薄的情况，在卷帘机同步卷速的情况下，较厚的一侧更快一些，这样就逐渐向着较薄的一侧倾斜，慢慢地在较薄的一侧会出现突出。 First of all, the difference in the thickness of the straw curtain results in the deviation of the curtain rolling machine in the greenhouse. Some vegetable farmers have to change the curtain every year to eliminate part of the worn curtain. Some vegetable farmers mix the old curtain with the new one. The new curtain is often compact and thicker. The old curtain is relatively loose and thin. If the matching is not reasonable, one side of the curtain is thicker and the other side of the curtain is thinner. In the case of synchronous rolling speed of the curtain machine, the thicker side is faster, so one by one. Gradually tilt toward the thinner side, and gradually appear prominent on the thinner side. 像这种情况可采用在较薄一侧铺垫草帘增厚的办法改善。在较薄一侧视情况添加部分新的或旧的草帘，使这一侧达到与另一侧一样的厚度，在卷帘机上卷时两侧能够达到同步，这样就能很好地改善跑偏的情况。 Such a situation can be improved by laying a thick straw curtain on the thinner side. Adding some new or old curtains on the thinner side according to the situation, so that the thickness of one side is the same as that of the other side, and synchronization can be achieved on both sides of the curtain winding machine, so that the running deviation can be improved very well. 再有呢就是草帘长短不一或者在固定时远近不一。草帘铺好以后需要把垂在棚前脸的草帘与大棚卷帘机的卷杆固定起来。不仅仅是固定好就可以了，需要进行试卷才能及时发现跑偏情况。有的菜农在安装草帘的时候请短工安装，其草帘固定松紧度不一致，若不及时检查，在使用过程中就会出现有的草帘尼龙绳被挣断，有的草帘却因松散出现褶皱。这样松紧度不一的草帘也会导致大棚卷帘机在拉放草帘时出现跑偏。 What's more, the length of the straw curtain varies, or when it's fixed, the distance varies. After the curtain is laid, it is necessary to fix the curtain hanging in front of the shed with the reel of the curtain rolling machine. Not only is it fixed, but it needs a test paper to find out the deviation in time. Some vegetable farmers in the installation of straw curtain, please install short-time, the straw curtain fixed tightness is inconsistent, if not checked in time, there will be some curtain nylon rope broken in the use process, and some curtain because of loose folds. This kind of straw curtain with different tightness will also cause the curtain rolling machine in the greenhouse to run off when pulling the straw curtain. 关键的还有就是棚面不平造成的大棚卷帘机跑偏。大棚的两侧墙体高度不一致的情况下，大家往往会因为影响不到大棚的采光而忽视这个问题，但两侧棚墙高度不一致会导致大棚棚面不平整，安装好草帘和卷帘机后就会出现卷起的草帘向一边跑的情况。假如这种由于棚面不平整造成的跑偏是短时间内难以调整的。这需要从大的方面来改善，即将棚墙的高度调整到一致，保证棚面的平整。这样在使用大棚卷帘机的时候才能让两侧卷杆保持平衡和同步。 The key is also the deviation of the curtain rolling machine caused by the uneven surface of the greenhouse. In the case of inconsistent wall heights on both sides of the greenhouse, people tend to ignore this problem because they can not affect the daylighting of the greenhouse. However, inconsistent wall heights on both sides will lead to uneven greenhouse surface. When the curtain and the curtain roller are installed, the curtain will roll up and run to one side. If this kind of deviation caused by uneven shed is difficult to adjust in a short time. This needs to be improved in a big way, that is, to adjust the height of the shed wall to the same level, to ensure the level of the shed. Only in this way can the rollers on both sides be balanced and synchronized when using the curtain rolling machine in the greenhouse. |
