The roller blind machine goes wrong? Three measures to adjust
Vegetable farmers often encounter such a situation, when the roller shutter machine moves upwards, the head of the machine heads southeast. When the nose was under the shed, it was on the east side of the pole, and when it reached the roof of the shed, the nose was far west. This causes the vertical pole and the floating pole to crook and tilt. How should it be adjusted?
In fact, this kind of "skewing" is caused by deviation, and there are many reasons for deviation, such as the inconsistency of the weight, thickness, and tightness of the straw curtains on both sides of the rollers, etc., but the main reason is the thickness of the straw curtain covered by the vegetable farmers. Unevenness, leading to inconsistent pace when rolling the grass curtain on the roller shutter machine, some are fast, some are slow, and the phenomenon of deviation gradually appears.
Vegetable farmers can take the following three measures to correct:
One is to thicken the grass thatch on both sides of the greenhouse, and increase the radius of the grass thatch at both ends of the roller.
The second is to set the grass thatch at both ends of the greenhouse on the bottom layer to make it contact with the greenhouse film to reduce friction and increase the winding speed.
The third is to learn from the method of installing heat preservation quilts, and connect the grass thatch of the whole greenhouse with nylon ropes and fix them together. For rear-mounted roller blinds, adjusting the tension of the drawstring to the same level can prevent "deviation". Of course, you can also stretch one side of the grass curtain in the shed to make temporary adjustments.
In addition, after the roller shutter machine deviates, it is recommended to select the rods reasonably according to the weight of the shed cover. In order to avoid the rod breakage caused by external forces such as strong wind, the vertical rod can be double rod form, welded into a triangle, or set on the top of the vertical rod The rope or steel wire is diagonally pulled on both sides to ensure the stability of the pole.
