Recently, a new type of warm-shed roller blind machine, different from the traditional concept, was jointly developed by a farmer technician and the agricultural machinery department in Tieling County and has been recognized by the majority of farmers. The machine is unique in structure, reliable in performance, high in efficiency, low in cost, suitable for a variety of heating sheds, and it is also suitable for a greenhouse without considering the provision of a shutter machine in civil works. A machine can take a few sheds and do not need to move the mainframe. The cost of a single machine can be reduced by more than half year-on-year. If a single machine with multiple sheds is used, the cost will be lower. At present, this technology has applied for national patents, and several companies want to purchase the technology. According to relevant sources, the technology has a lot of room for development.
