With the improvement of urban and rural people's living standards, the cultivation of winter fresh vegetables, fresh fruit greenhouses flourish, increasing its size. However, in greenhouse operations, the volume is one of the major job shop Caolian most time consuming aspects, especially in the cold winter in the morning and evening, in harsh conditions bleak, rolling machine specifications, farmers stand greenhouses atop engaged in hard labor lay heavy volume of straws, the situation can be imagined. For a greenhouse is 80 meters long, every day in the morning and pull start, lay down in the evening, each take about 40 minutes. Strictly speaking, the winter sun and temperature are "fruit and vegetable greenhouses" in the normal growth of crops depend on scarce resources. Farmers to race against time, hard work is imagined. But this is still not solve the problem, labor since the "fruit and vegetable greenhouses" insulation curtain opening and closing time is relatively concentrated, caused by inadequate and elapsed time is too long, it has severely restricted the "fruit and vegetable greenhouses' production efficiency and development. Features Benefits back wall fixed greenhouses rolling machine: rolling machine body structure is simple, fixed bracket can buy their own triangle welding, rolling machine principle, easy to install. With respect to shed self-propelled surface greenhouses rolling machine, and low cost. Because the chassis on the back wall, insulation was put Luocao thatch or after, Roof and no obstructions, rolling machine, so the use of a plastic film as "scum" can be, and can be communicated or grass thatch insulation was together Pull release. Cons: Because of a rolling machine needed more rope, and are in the grass thatch or insulation was over, in the course of its use, once involved in the operator's clothes (wear a coat in winter), or rope wrapped fingers, often resulting in personal accident, a big security risk. In addition, since each rope uneven force, after a period of time, tightness, small rolling machines, often need to adjust rope tension, and almost every year to replace a rope. In addition, the type of rolling machine stand, some buried in the rear roof greenhouses, a long time, its destructiveness, or rain wet the back wall invasion, causing collapse. The new rolling machine, Tian Yun wholesale vegetable greenhouse construction (certified), rolling machine consists of Cangshan County Tianrun cultivation of professional cooperatives. Cangshan County Tianrun planting cooperatives (www.tianrun8.net) Shandong Linyi, fruits leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Run vegetable wholesale leadership in the field with the staff warmly welcome all inquiries negotiations to create Tianrun vegetable wholesale better future.
