Inside Shading System

Inside shading and heat preservation system in greenhouse. Shading net insulation consists of aluminum foil and polyester woven. Special aluminum foil and polyester to give superior radiation reflection and transmission function, so as to ensure the daytime indoor temperature is low and the energy saving effect is very good, at night, the crop temperature and the surrounding environment temperature is basically equivalent. A good indoor climate conditions to avoid foliar condensation, reduce disease, and reduce the cost of energy.

In the net structure in the abundant water vapor through the curtain to prevent lower condensation; because the screen is a kind of high intensity UV resistant, anti-static products, it can stay clean and efficient in many years. The ultraviolet stabilizers added in the material have a resistance to common chemicals in the greenhouse.

Drive system using a rack and pinion drive system, the specific breakdown as the following:

1. The curtain line: support, pressure line for the ф2.2mm diameter polyester thread, tensile strength 270kgf, support line spacing is 0.5m, the pressure line spacing is 1 meters; support, pressure line adopts transparent curtain line, with excellent ageing resistance moisture;

2.Rack and pinion: use the greenhouse special pull screen rack, L=3965mm ,T=2.75mm, reliable quality, stable operation;

3. Transmission shaft: use the national standard 1.0 "hot galvanized steel pipe, the central part of the chain coupling and motor connected, and the rest of the rack, rack spacing 4.0m. The circular motion of the drive shaft is converted into a uniform linear motion through a rack;

4. Push rod: galvanized steel pipe with φ32 x 1.5mm, each rack is connected with 1 columns, and the same direction of the roof; and the pushing rod is connected to the drive rod for special aluminum curtain, transverse along the span direction, to drive the curtain to open and close.

5. The connectors: used hot dip galvanized layer thickness not less than 60um;

6. Motor: use domestic motor, power 0.55Kw, speed ratio 300:1, limit 5-55 turns, the power supply using three-phase common frequency, AC three-phase 380V, frequency 50Hz.

Opening and closing method

Greenhouse system hoist adopts automatic and manual control mode, along the direction of opening and closing the greenhouse bays, the system has the advantages of simple operation, stable operation;

Control system

The cabinet is equipped with a greenhouse automatic / manual switch, the motor can realize opening and closing in the shade under the command of the operator. The motor comes with working limit and safety switch to achieve safe and reliable action.
