Description

A kind of multi-film double-skeleton built-in thermal insulation quilt plastic shed

technical field

The utility model relates to an agricultural greenhouse, in particular to a multi-membrane double-skeleton built-in insulation for cultivating vegetables, flowers, fruit trees, fruits and other crops, which can prevent insects and adjust temperature and humidity according to seasons.

Warm quilt plastic shed.

Background technique

The spring and autumn greenhouse is a necessary configuration for growing vegetables, flowers, fruits and other crops under the condition of artificially changing the small environment. It is generally a steel frame greenhouse. In the traditional spring and autumn greenhouse, there are generally poor thermal insulation, poor ventilation, and excessive summer temperature. High temperatures are not conducive to crop growth, and crops cannot grow when the temperature is too low in winter. The use time can only be limited to early spring and late autumn, and the use time is very limited, so that the crops cannot grow year-round in the shed, and it is far from reaching the "three highs" of facility vegetables, namely high quality, high yield, and high benefit.

Utility model content

The problem to be solved by the utility model is aiming at the above-mentioned problems existing in the traditional steel frame greenhouse, providing

The utility model relates to a multi-film double-frame built-in thermal insulation quilt plastic shed that can adjust temperature and humidity according to seasons.

In order to solve the above problems, the utility model adopts the following technical solutions:

A multi-film double-skeleton built-in thermal insulation quilt plastic shed, comprising an outer shed skeleton, an inner shed skeleton is arranged inside the outer shed skeleton, there is a certain space interval between the outer shed skeleton and the inner shed skeleton, the outer shed skeleton is The outer layers of the arch shed skeleton and the inner arch shed skeleton are respectively covered with plastic films, and several ventilation devices are arranged above the outer arch shed skeleton.

Below is the further improvement of the utility model to above-mentioned scheme:

The left and right sides of the outer shed skeleton are respectively equipped with manual film rolls for opening windows and ventilating the outer shed.

Further improvement: electric film rolls for rolling and unwinding the plastic film are provided above the left and right sides of the inner arch shed skeleton.

Further improvement: the inner arch shed skeleton is covered with a thermal insulation quilt, and the left and right sides of the inner arch shed skeleton are respectively provided with a shutter machine and a roller shutter rod for rolling out the thermal insulation quilt.

Further improvement: an outer shed sliding door is provided at both ends of the outer arch shed skeleton, and an inner shed sliding door is respectively provided at both ends of the inner arch shed skeleton.

The utility model adopts the above scheme and has the following advantages:

1. It occupies a small area, saves land, and improves the utilization rate of planting area.

2. Wind resistance can resist ten-level winds, and the snow load capacity is strong with 30cm thick floating snow (in the case of hanging vegetables and fruits in the shed).

3. Strong load-bearing capacity, can hang vegetables, not only can produce leafy vegetables, but also produce tomatoes, cucumbers and other vegetables that need hanging vines.

4. Good thermal insulation and adjustable temperature: According to the observation at 7:00 in the morning in Shouguang, the temperature outside the shed is -16°C, the temperature inside the shed is +6°C, and the temperature difference between inside and outside the shed can reach 22°C. Generally, the temperature inside the shed is 40°C in spring and autumn, but the temperature inside this shed is 30°C.

5. Strong light transmission: Because there are no walls on three sides like the east-west solar greenhouse, it has strong light transmission, and the temperature and light in the shed are well controlled, which is conducive to the growth of crops. Even in the smoggy weather in late winter, the insulation quilt can be pulled normally, the temperature in the shed will also rise, and the vegetables will grow normally. Generally, pulling the curtain at this time in the warm-winter greenhouse will cause the temperature in the shed to drop.

6. Labor saving: This shed is not afraid of "wind, rain, and snow". What's more valuable is that this shed does not need manual snow removal, which greatly saves manpower and material resources.

7. The shed has high value preservation: The main frame of the shed is all made of hot-dip galvanized steel, which is anti-corrosion and has a service life of more than 20 years.

8. The shed is easy to be automatically controlled, and is convenient for large-scale industrial planting of agriculture.

9. Detachable and relocated, easy to install, no column, easy to work.

10. Strong adaptability, not affected by the thickness of the soil, the strength of the viscosity, and the depth of the water level under the soil.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.
