The country's latest patented product ZJ-I type portable greenhouse shutter.
With the rapid development of facility agriculture, the use of rolling machines in greenhouses is becoming increasingly widespread. These devices help retract curtains efficiently, significantly reducing labor intensity and saving time. By extending the effective light exposure by 1–2 hours, they enhance plant yield and quality while improving overall greenhouse productivity. Studies have shown that increasing daily light exposure can boost crop yields by 10% to 15%.
The latest national patent product, the ZJ-I portable greenhouse shutter, features a unique design with multiple advantages, including high power, compact size, lightweight construction, easy installation and removal, manual operation capability, secure connection rods, and long service life. This innovation overcomes the limitations of traditional roller shutters, which are often bulky, difficult to install, and prone to damage at the connecting points. It is suitable for a wide range of horticultural applications, such as vegetables, flowers, seedlings, fruit trees, and edible mushrooms.
Developed in collaboration with Professor Shannongda, this product has undergone on-site testing and practical application. It addresses the shortcomings of traditional systems, offering improved performance, reliability, and user-friendliness. The ZJ-I model allows for manual operation during power outages, ensuring that curtain adjustments can still be made without affecting the crops.
The product's working performance matches international standards and has been widely adopted in experimental farms. Currently, it represents one of the most advanced technologies in China. Compared to similar products, the ZJ-I offers several key advantages:
1. **Compact and Lightweight**: With dimensions of 50cm x 30cm x 25cm and a weight of just 29kg, it is highly portable. It supports a 1.7kW motor capable of driving 50–100m of straw curtains.
2. **Easy Installation and Removal**: Its lightweight structure makes it ideal for large-scale farming, reducing overall costs. It also helps prevent losses during nighttime operations.
3. **Flexible Operation**: The device includes an automatic locking mechanism, allowing users to stop the curtain at any position. Manual operation is also possible, ensuring continued use even during power failures.
4. **Low Installation Cost**: Unlike conventional systems, the ZJ-I does not require an additional operating bracket. It can run automatically along the side of the greenhouse, simplifying installation and eliminating the need for secondary roller blinds.
This innovative solution combines efficiency, durability, and user convenience, making it a valuable tool for modern greenhouse management.
