Greenhouse mechanical rolling shutter technology

Greenhouse shed mechanical rolling shutter technology is a technology that uses roller blinds to automatically wind the greenhouse insulation cover (grass curtain, insulation, etc.). In the north of China, especially in the northeast region, in the early spring, late autumn and winter greenhouses, straw curtains and insulation are needed to increase the temperature inside the greenhouse. It takes time and effort to manually roll, and the labor intensity is high. The mechanical shutter can not only extend the lighting time, raise the temperature inside the booth, reduce labor intensity, but also increase the economic efficiency of greenhouses. From the perspective of the development of facility agriculture in recent years, the greenhouse rolling shutter technology has been recognized by a large number of planting households, and its role has become increasingly apparent. It has become one of the major engineering technologies for greenhouses.
First, the main role of greenhouse rolling shutter technology
1. Increase sunshine and increase greenhouse temperature. By shortening the revolving curtain time, it is generally possible to increase the sunshine time by nearly two hours per day and increase the temperature in the greenhouse by 3°C to 5°C.
2. Improve labor productivity and reduce labor intensity. It can generally increase labor productivity by 15 times.
3. Reduce the wear of the insulation curtain and extend the service life of the insulation curtain. Because the rolling process runs smoothly and there is no friction between the rope and the insulation curtain, the insulation curtain can be used for an extended period of 1 to 2 years.
4. Shorten the crop growth cycle, mention the morning market, and increase product economic efficiency. Due to the increase in temperature in the greenhouse, rapid growth, so that the crop is early maturity, shorten the crop growth period, generally allow the crop to be listed in advance for 5 to 10 days, due to the anti-season production, the size of the anti-seasonal volume is directly related to the price of the product.
5. Can get better economic benefits. By reducing the number of workers, reducing the damage of insulation curtains, increasing the yield of crops, and increasing the off-season volume, the economic benefits can be significantly improved.
Second, the type and working principle of shutters Blinds have a variety of classification methods, according to the form of power divided into manual and electric type, according to the form of work are divided into fixed and walk type. The fixed type shutter is fixed on the brick wall of the back wall of the greenhouse, and the grass curtain is rolled up with mechanical power. The grass curtain is rolled down by using the slope of the greenhouse and the weight of the straw curtain. The rolling machines of this type are all Early installations were expensive, and the greenhouse had to have a certain slope. If the slope was too flat, the straw curtain would not roll down. Walking type is that there is no brick wall on the back wall. The motor and the speed reducer move together on the shed surface. The power of the shutter is used to freely roll up and down the straw curtain, which is not limited by the slope size of the greenhouse. The installation is simple, the construction cost is low, and the efficiency is high. Neat and tidy, is a widely used form.
Three, cantilever self-propelled roller shutter machine is widely used in our city is now widely used is a self-propelled roller shutter, it consists of base, arm, swing arm, three-phase or single-phase motor, reducer, roller blind shaft and motor The seats are composed of single-phase motors with powers of 1.1-2.2kw and lengths of 30-80m. The arm, swing arm, and roller blind shaft are all 2?

2. To reduce labor intensity, turn on the power roller shutter and roll it on its own without manual operation.
3. Extend the lighting time, improve the quality and yield of crops, and promote the early maturing of crops.
4. Good security, high reliability, protection of greenhouses.
5. Neatly laid, the material on the shed is not damaged.
6. Easy to operate, can be stopped or started anywhere on the shed.
7. The structure is simple and the price is low.
Fourth, the use of attention The shutter in the use and maintenance should pay attention to the following issues:
1. Prevent the lack of a phase power supply when the power is turned on. If one phase power supply is missing, the motor will be burnt out.
2. The transmission part of the main engine (such as reducer, transmission bearings, etc.) should be added once a year, and the transmission should be added with antifreeze oil.
3. During the installation process, the length of the roller cord (elasticity) is adjusted, and the rolled straw curtain is placed in a straight line. During the use process, the roller blind cords should be adjusted frequently. If the ropes are of different lengths, the straw curtains will have different elasticities and the rolled grass curtains will appear curved. In use, the torque force of the shutters and reels will be increased. Affects the effect of use or damages the shutter and reels.
4. The bottom of the screen (ie where it is connected to the roller blind shaft) must not be too wet. Over-wetting will make the screen heavy and difficult to roll up. In use, it is best to cover the straw with a plastic sheet to prevent the rain and snow from wetting the straw curtains, as well as clear snow.
5. Paint anti-rust paint on parts every year.
V. Technical Standards for Rolling Blinds Although there are no clear technical standards for shutter devices, the following parameters should generally be referenced for cantilever self-propelled roller shutters:
(1) The length of a roller blind is ≤ 80m and the roller blind weight is <4000kg.
(2) Volume and curtain time <10min.
(3) Reel speed <1.5r/min.
Sixth, technology application effect The greenhouse shutter is the future of greenhouse equipment necessary for mechanical equipment and development direction, it changed the traditional manual shutter operation method, improve the efficiency of more than 15 times than manual operation, to solve the roll of the curtain labor intensity The problem has improved the open-air operating environment and improved labor efficiency. According to tests, in a 70-meter-long greenhouse, the rolling machine takes only 8 minutes to roll, and manual rolling requires 2 people to work for 2 hours. In contrast, mechanical shutters can extend the lighting time by nearly 2 hours per day. Make full use of the time difference to increase and maintain the temperature in the shed, so that the shed temperature is increased by 3 to 5, the plant growth cycle in the shed is shortened, early maturity, plant species are listed 5 to 10 days ahead of the artificial roller blind, and the price per kilogram increases by an average of 1 ~1.5 yuan. At the same time, it can reduce the damage of grass curtains, extend the service life of grass curtains, and save the labor force can engage in other work and create more output value.
