Greenhouse outside sunshade system introduction

First, the external shade system

External shade frame (column, beam, stringer), electric reducer, external shade net, black screen line, black screen curtain line, drive shaft, drive shaft, screen gear rack, rack push rod, support Hanging round, drive side aluminum profiles, positioning retainer, counter board and the corresponding connection accessories;

Second, external shade system brief

External shade system Compared with the internal sunscreen insulation system, the external sunshade system can effectively block the light outside the greenhouse, thus playing a role in cooling shade.

1, the system is mainly suitable for summer shading, cooling, so that part of the sun into the greenhouse, to ensure that crops avoid glare burns, while reducing greenhouse temperature.

2, by adjusting the shade net open close, to meet the greenhouse's demand for light.

3, high-intensity shade net with anti-hail protection.

Third, the outer shade system skeleton

Outer shade column column with 50 × 50 × 2.0 square tube, beam with 50 × 50 × 2.0 square tube, column and the second column between the columns are used Ф32 hot dip galvanized tube as a diagonal brace. All steel components are hot dip galvanized, with good outdoor rust and corrosion resistance.

Fourth, the outer sun screen

At the top of the greenhouse, the outer sunshade is installed 0.5m above the roof. The shading material adopts the air-permeable shading screen with 65% shading rate and 25% energy saving rate. The shading net adopts domestic black shading netting whose shading rate is 70 %. Using high-density polyethylene, UV stabilizers and anti-oxidation made after the treatment. With non-off-line, wind-resistant, anti-UV, anti-aging, smoothness and good, the service life of 8 years.

Fifth, the external shade drive system

Rack and pinion drive system, that is, gear and rack as the main driving traction material, the work of electric reducer through the rotating shaft driven gear movement, the gear driven rack engagement with its movement, which is connected to the racks at both ends of the push rod in Rack traction, driven by the activities of the system side to achieve the goal of opening and closing shade.

The greenhouse sunshade insulation system driven by rack and pinion drive system, stroke 3700mm, speed 0.4m / s. The system has the following features:

1, smooth operation, accurate walking;

2, Large control area, high control precision, good system airtightness;

3, long service life, easy maintenance; high-quality shade net effective life of five years, the actual use of playing more than five years.
