FAQ

　　First, the first greenhouse roller shutter machine power transmission operation, about 1 meter up, look at the straightening of the curtain, if the curtain is not straight, you can analyze the reason for the lack of straightening according to the specific situation, and take straightening measures. In this operation, whether the curtain is straight or not, the greenhouse roller shutter machine must be returned to the initial position, the purpose is to test run, one is to make the straw curtain roll, and the other is to lightly run in the greenhouse roller shutter machine.

Second, the second power transmission operation, the greenhouse roller shutter machine is rolled up to about 2/3, repeat step one, the purpose is still to promote its straw curtain to further roll and moderate running-in of the greenhouse roller shutter machine. Then, the greenhouse roller shutter machine is returned to its initial position again.

Third, see whether the straw curtain is rolled up neatly and straight, and whether there is any deviation; If the above phenomenon is found, it should continue to be adjusted until it meets the practical requirements. Finally, the self-adhesive safety mark is firmly posted in the appropriate part of the main rod of the greenhouse roller shutter machine to show that the user pays attention to the safety of operation.

Fourth, before the third power transmission, carefully check whether the motor, greenhouse roller shutter machine has obvious temperature rise phenomenon, abnormal sound, peculiar smell, if the temperature rise does not exceed the ambient temperature of 40 °C, and no greenhouse roller shutter machine is found to have abnormal sound, odor, can carry out the third power transmission operation, so that the greenhouse roller shutter machine in place.

During commissioning, attention must also be paid to:

First, before use, the body of the greenhouse roller shutter machine should be injected with an appropriate amount of engine oil (the specific amount is determined according to the size of the roller shutter), and it should be replaced once a year in the future.

Second, during the rolling process of the greenhouse roller shutter machine, the operator must stand on the two hills of the greenhouse with the switch in hand, and it is strictly forbidden to stand in front of the shed, and stay away from the host and the rotating straw curtain and insulation quilt.

3. When the greenhouse roller shutter machine rolls up to 30 cm on the roof of the shed, it must be stopped. If the brake fails, please quickly put the reverse switch in the reverse (reverse) direction so that the roller shutter machine can be put down normally and then repaired.

　　Fenggong said that the electric film reel is now a ventilation equipment, which brings a lot of convenience to the majority of growers, so it is loved by growers, and has also used and installed the electric film reel, the following will introduce you to the installation method of the electric film reel. Before installing the film reel, first prepare the necessary materials, steel pipes, laminating cards. The steel pipe is made of 25mm galvanized pipe, and the lamination card is also used 25.

After the material is ready, it is to start the installation, before installation, first determine whether the greenhouse is roof ventilation or measured ventilation, top ventilation first to make telescopic rod, telescopic rod production is relatively simple, that is, thin pipe inserted in the thick tube. If it is an installation test paper, it is relatively simple. A fixed wing root pole at one end of the greenhouse will do.

The electric film reel can also be connected to the automatic temperature controller, so that thousands of miles away, the use of mobile phones can know the temperature in the greenhouse, according to the needs of vegetables for temperature, according to the temperature to determine the opening or closing of the film winder, to achieve the whole automatic management.

　　The greenhouse film reel should be filled with antifreeze gear oil. During installation and use, it is necessary to frequently check whether the screws of the host and each connection are loose, and whether there are problems such as fracture or open welding at the welding place. After each use, cut off the total power supply outside the shed in time.

Here's a look at safe use:

1. According to the length, width, arch and weight of the agricultural film of the greenhouse, select the appropriate host according to the standard, pay attention to leaving a load margin, prohibit full load and overload operation, and take necessary safety and anti-theft measures for the motor.

2. According to the weight of the coil film, use the support rod, pusher, roll rod and bolt according to the standard to avoid the unreasonable configuration of the rod and screw rod.

3. The cables and other power distribution equipment purchased by the user should be qualified products that meet the national standards to ensure the safety of electricity and the safe operation of the host.

4. Fix the reverse switch on the main engine support rod, and add a control knife gate in front of the reverse switch to ensure that the power supply can be cut off in time when the reverse switch fails.

5. The host has added a sufficient amount of qualified lubricating oil when leaving the factory, and the user does not need to re-join.

6. In ice and snow weather, clean up the cold film and start the film reel to prevent damage to the agricultural film due to rain and snow freezing.

7. It is forbidden to touch the reel rod when the reel is reeled, and the reel should be turned off in time after the reel is rolled in place to prevent the reel from turning offside into the shed.

8. During the installation and use of the user, when the pole and roll rod deviate, the bolt should be adjusted, straightened and tightened in time to ensure the normal operation of the main engine and members and prolong the service life.

Facility greenhouses are buildings that use daylighting covering materials as all or part of the envelope material for cultivation of plants in winter or other unsuitable growing seasons for open-field plants.

1. Common facilities: greenhouses

The facility greenhouse can be divided into single building and continuous building according to the layout of the plan, metal structure and non-metal structure according to the main structural material, and soft covering material and hard covering material according to the type of covering material. In Zhejiang and other southern provinces, commonly used facilities greenhouses are steel frame sheds, glass greenhouses, solar panel (PC) greenhouses, rain shelters, shade sheds, characteristic sheds, etc.

(1) The most widely used steel frame greenhouse is the prefabricated hot-dip galvanized steel pipe greenhouse. (1) Single steel frame greenhouse, the span of the greenhouse is 6~8 meters, the shoulder height is 1.5~1.8 meters, the top height is 2.5~3.3 meters, and the length is 30~70 meters, and its basic skeleton composition includes arches, poles, poles (for shedheads at both ends), diagonal braces, referred to as "three poles and one brace". (2) Continuous steel frame greenhouse, a single span of 6~8 meters, gutter height of 2.5~3 meters, top height of 4.2~5 meters, length of 30~60 meters, there are main and auxiliary columns, and some are equipped with internal and external shading and insulation curtains. The pipe diameter of the steel frame greenhouse is 22 mm, 25 mm, 32 mm, the pipe wall thickness is 1.2~1.5 mm, and the inner and outer walls are hot-dip galvanized, and plastic film is used as the covering material.

(2) Glass greenhouse commonly used 5 mm thick float glass or double-layer insulating glass as transparent covering material, glass inlay material using aluminum alloy profile, the edge of the glass and aluminum alloy profile connection with anti-aging rubber strip sealing. The span of glass greenhouse is usually 6.4 meters, 9.6 meters, 12.8 meters, the height of the gutter is 3~4 meters, and the bay is mostly 4 meters. The advantages are good light transmission, good heat preservation, easy cleaning of dust accumulation, and long life. The disadvantages are poor impact resistance, high cost, and the structure is mostly Monolo spire.

(3) Sunshine panel (PC) greenhouse solar panel is a transparent covering material with polycarbonate as the main raw material, including single-layer corrugated board, double-layer or three-layer transparent hollow solar panel, and the skeleton adopts hot-dip galvanized steel frame assembly. The advantages are good heat preservation, sealing and impact resistance, and the disadvantages are that the surface is easy to accumulate dust, not easy to clean, and high cost.

(4) The rain shelter is composed of cement columns, steel pipes, etc., mostly "Y" or "umbrella" shaped structures, the top covering material is mostly plastic film, and the surrounding is ventilation without buckle film or insect net. In the rainy spring and summer, crops can be protected from direct rain showers, thereby reducing disease. It is mostly used for rain-sheltered cultivation or summer seedlings of fruit trees, fast-growing leafy vegetables, etc.

(5) Shade sheds are cultivation facilities that provide shade for plant growth. The pillars and rungs are made of hot-dip galvanized steel pipes, which are fixed to the ground and covered with shading nets with different light transmittance according to the different needs of plants, with a height of about 2 meters. Simply put, the function of the shade shed is to shade and cool down in the summer and autumn strong light and high temperature seasons; In the frost season of early spring and late autumn, it plays a certain protective role on the plant from the harm of frost.

(6) Characteristic shed Characteristic shed refers to a shed specially designed and made for some agricultural production, such as bayberry steel frame net shed, aquatic facilities breeding greenhouse, loquat shed, etc.

1. The newly purchased mattress may have the smell of new products due to long-term sealing and packaging, as long as the indoor air circulation is maintained or placed in a ventilated and cool place for 72 hours, the odor will be significantly reduced. 

2. Flat on a smooth and breathable bed surface to make the mattress evenly supported and breathable. 

3. When using, avoid local force and heavy pressure on the cushion surface, so as not to cause local depression and deformation of the mattress and affect the service life. 

4. Avoid scratching fabrics such as sharp-angle utensils or knives when using. 

5. Keep it dry during use to avoid damage to the surface of the mat such as liquid leakage, high temperature ironing or open flame. 

6. It is recommended to put on mattress covers or better quality sheets when using to avoid staining the surface of the mattress.
