Jianda Agricultural Venlo Glass Vegetable Growing Tomato with Hydaroponic Soilless Cultivation System

Second, greenhouse program description Greenhouse foundation: Combined with the local geography and natural conditions, the greenhouse foundation is slotted at a depth of about 1.5 meters, and C20 coagulation is poured on-site (it can be adjusted appropriately according to the local address conditions). Inside the greenhouse is a point foundation, surrounded by a strip foundation, pouring the ring beam on site to improve the overall strength of the greenhouse, the greenhouse is surrounded by a 0.5-meter-high brick wall above the ground, and cement mortar plaster, to provide heat preservation and prevention of winter sweeping winds. The internal foundation of the greenhouse adopts point-type foundation, and the depth reaches below the frozen upper layer. Outdoor water dispersion: A circle of 150# loose water, 5 cm thick and 0.5 m wide with a slope of 5%, is made around the outside of the greenhouse to prevent the foundation from being directly washed away. (i) Main skeleton The greenhouse adopts light steel structure of small roof multi-drainage phase main skeleton. The main structure model has been tested and calibrated by stress software, and the structure is very stable. And has a unique roof drainage structure (ii) Gutter dew collection A wider hot-dip galvanized dew collection tank is installed under the inner side of the gutter, and the dew drops formed on the covering material and the inner surface of the gutter will flow into the dew collection tank and be guided to one end of the greenhouse to be drained away, which effectively reduces the problem of greenhouse dew dripping. (iii) Greenhouse exterior covering---sunshine boards

(D) External sunshade system 1、Skeleton of external sunshade 2、Sunshade mesh is selected as black color sunshade mesh. 3、To curtain line 4. Transmission mechanism: The motor drives the drive shaft through the transmission mechanism, and the drive shaft drives the drive rod to move parallel to the curtain wire through the connecting parts, and the drive rod pulls one end of the curtain to unfold slowly, and after all the unfolding touches the travel limiter switch, the motor stops, and the operation of the trip ends. The control box is equipped with manual control, if you need to stop in the middle, you can If you need to stop in the middle, you can press the stop button to stop the operation. (E) Inner shade insulation system 1、Thermal insulation shade curtain Choose the slow slow slow inside the aluminum heat preservation shade screen Summer shade water retention and moisturizing, winter heat preservation, regulating the rate of shade. 2、To curtain line 3、Transmission mechanism: The motor drives the transmission shaft through the transmission mechanism, the transmission shaft drives the driving rod to move parallel to the curtain wire through the connecting parts, the driving rod pulls one end of the curtain to unfold slowly, all unfolded after touching the travel limiter switch, the motor stops, the end of the travel operation. The control box is equipped with manual control, if you need to stop in the middle, you can press the stop button, you can stop l run.

(vi) Greenhouse natural ventilation system (top opening window system) 1. Design conditions: Excluding the residual heat in the greenhouse, so that the ambient temperature in the greenhouse is maintained within the range suitable for crop growth. Excluding excess water in the greenhouse, so that the ambient humidity in the greenhouse is maintained in the range suitable for crop growth. Adjust the air composition inside the greenhouse, expel harmful gases, and keep the freshness of the air inside the greenhouse. 2, system composition: Set the insect-proof net at the skylight. Press the control box start switch button, the motor starts. The motor drives the drive shaft through the transmission mechanism, the drive shaft drives the rack and pinion movement through the connecting components, the skylight opens and touches the trip limiter switch, the motor stops and the trip operation ends. The control box is equipped with manual control, if you need to stop in the middle, you can press the stop button to stop the operation.
