Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse ventilation technology, and in particular to a ventilation device applied to agricultural greenhouses. Background Technology

[0002] In agricultural greenhouse cultivation, ventilation is an important means of regulating the internal environment of the greenhouse, which has a significant impact on the growth and yield of crops.

[0003] Chinese Patent CN221329678U discloses a ventilation device for vegetable greenhouses. The device features a detachable connection between the greenhouse roof and the greenhouse body via connectors. The greenhouse, consisting of a steel frame and glass structure, can be ventilated by removing the roof according to actual planting needs. Ventilation can be performed when outdoor temperatures are suitable, and during winter when temperatures are low, ventilation can be achieved through ventilation pipes. The first and second air inlets on the ventilation pipes can be connected to a hot air blower and a cold air blower, allowing for control of the intake of hot and cold air based on the actual temperature inside the greenhouse. This ventilation system helps control the temperature within the greenhouse, ensuring normal vegetable growth even in low temperatures. However, under varying environmental conditions and different crop growth requirements, the ventilation volume is difficult to adjust, leading to an unstable growing environment for crops. Therefore, this invention provides a ventilation device for agricultural greenhouses. Utility Model Content

[0004] The main purpose of this utility model is to provide a ventilation device for agricultural greenhouses, in order to solve the problem in related technologies that the ventilation volume of greenhouses is difficult to adjust under changing environmental conditions and different crop growth needs, resulting in an unstable crop growth environment.

[0005] To achieve the above objectives, according to one aspect of this utility model, a ventilation device for use in agricultural greenhouses is provided, comprising a greenhouse frame, the greenhouse frame including a base set on the soil, a greenhouse roof slidably disposed on the base, insert plates fixedly connected to both sides of the bottom of the greenhouse roof, the insert plates slidably mounted on the base, and a plurality of ventilation openings penetrating through the insert plates, ventilation ducts symmetrically embedded in the left and right sides of the greenhouse roof, a plurality of blowers symmetrically fixedly disposed on the outer wall of the greenhouse roof, the blowers being used to input airflow into the ventilation ducts, and a sunshade plate fixedly disposed on the greenhouse roof, the lower end of the sunshade plate being inclined outward.

[0006] Furthermore, the pedestal is provided with slots, the insert plate is slidably installed in the slots, and each vent is fixedly provided with a mesh plate for intercepting impurities.

[0007] Furthermore, fixing plates are symmetrically fixed to the outer walls of both ends of the upper end of the canopy, and a sliding groove is opened in the fixing plate, and a screw is threaded through the sliding groove of the fixing plate.

[0008] Furthermore, sliders are symmetrically fixed to the outer walls at both ends of the lower end of the canopy. The sliders are slidably installed in the slide grooves, and the screws pass through the sliders and are threadedly connected to them.

[0009] Furthermore, the outer side of the roof is a protective film, the inner side of the roof is an insulation film, a ventilation interlayer is provided between the protective film and the insulation film, and several through holes are provided through the protective film, the ventilation interlayer and the insulation film.

[0010] Furthermore, the ventilation duct is installed within a ventilation interlayer, and the ventilation interlayer is filled with lightweight foam near the perimeter of the ventilation duct. The ventilation duct is provided with several air outlets that communicate with it, and the diameter of the air outlets gradually increases.

[0011] Furthermore, each blower is fixedly connected to a duct, and one end of the duct is connected to a ventilation duct.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This ventilation device, applied to agricultural greenhouses, has ventilation openings on the insert plate. By sliding and adjusting the depth of the insert plate in the slot, the exposed area of ​​the ventilation opening can be adjusted, enabling flexible adjustment of the ventilation volume. This allows farmers to provide a more suitable growing environment for crops based on the environmental conditions inside the greenhouse and the growth needs of the crops.

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide a ventilation device for use in agricultural greenhouses, including a greenhouse frame 1. The greenhouse frame 1 includes a greenhouse base 11 set on the soil. A greenhouse roof 12 is slidably disposed on the greenhouse base 11. Insert plates 13 are fixedly connected to the bottom two sides of the greenhouse roof 12. The insert plates 13 are slidably installed on the greenhouse base 11, and a plurality of ventilation openings 131 are opened through the insert plates 13. Ventilation ducts 5 are symmetrically embedded in the left and right sides of the greenhouse roof 12. A plurality of blowers 4 are symmetrically fixedly disposed on the outer wall of the greenhouse roof 12. The blowers 4 are used to input airflow into the ventilation ducts 5. A sunshade 3 is fixedly disposed on the greenhouse roof 12, and the lower end of the sunshade 3 is inclined outward.

[0029] The greenhouse base 11 has slots, and the insert plate 13 is slidably installed in the slots. Therefore, by sliding and adjusting the depth of the insert plate 13 in the slots, the exposed area of ​​the vent 131 can be adjusted. When the insert plate 13 is fully inserted into the slot, the vent 131 is completely blocked, and there is almost no ventilation inside the greenhouse. When the insert plate 13 is partially or completely slid out of the slot, the vent 131 is gradually exposed, allowing outside air to enter the greenhouse, thereby adjusting the ventilation volume. This allows farmers to flexibly adjust the ventilation volume according to the environmental conditions inside the greenhouse and the growth needs of the crops, providing a more suitable growing environment for the crops. In addition, each vent 131 is fixedly equipped with a mesh plate 132 for interception, preventing leaves, dust and other impurities from the outside environment from entering the greenhouse through the vent 131 and causing pollution or damage to the crops.

[0030] Fixing plates 111 are symmetrically fixed on the outer walls of both ends of the upper end of the canopy 11. The fixing plates 111 have grooves 112 inside, and the fixing plates 111 are threaded with screws 113 through the grooves 112.

[0031] Slider blocks 125 are symmetrically fixed to the outer walls of both ends of the lower end of the greenhouse roof 12. The sliders 125 are slidably installed in the slide grooves 112. The screws 113 pass through the sliders 125 and are threadedly connected to them. Therefore, when it is necessary to adjust the exposed area of ​​the vent 131, the farmer can rotate the screws 113 on both sides at the same time. Since the screws 113 and the sliders 125 are threadedly connected, the rotation of the screws 113 will drive the sliders 125 to move in the slide grooves 112. As the sliders 125 move, the insert plate 13 will also slide in the slot, thereby changing the exposed area of ​​the vent 131. Therefore, the farmer can flexibly adjust the depth of the insert plate 13 in the slot, thereby adjusting the ventilation volume. This not only improves the efficiency of ventilation management, but also provides more possibilities for environmental control inside the greenhouse.

[0032] It should be noted that in this embodiment, the power source for driving the screw 113 to rotate is a motor installed on the bracket 11. The output shaft of the motor is fixed coaxially with the screw 113 through a coupling, driving the screw 113 to rotate. The motors on both sides are controlled by the same switch, so they can start and stop synchronously, ensuring the synchronization of the two screws 113.

[0033] The outer side of the roof 12 is a protective film 121, which effectively blocks external factors such as ultraviolet rays, rain, and hail from damaging the interior of the greenhouse. The inner side of the roof 12 is an insulation film 122, which effectively reduces heat loss from the interior of the greenhouse and improves the insulation effect. A ventilation interlayer 123 is provided between the protective film 121 and the insulation film 122. In order to further enhance the air circulation effect inside the greenhouse, several through holes 124 are provided through the protective film 121, the ventilation interlayer 123 and the insulation film 122. These through holes 124 can serve as channels for air exchange between the inside and outside of the greenhouse.

[0034] Ventilation ducts 5 are installed within the ventilation interlayer 123, allowing them to be evenly distributed on the top of the roof 12. The ventilation interlayer 123 is filled with lightweight foam near the perimeter of the ventilation ducts 5, which not only enhances the structural strength of the roof 12, making the greenhouse more stable in the face of harsh external environments, but also fixes the position of the ventilation ducts 5, preventing them from shifting or being damaged in strong winds or other severe weather. Several air outlets 51 are provided on the ventilation ducts 5, which extend into the interior of the greenhouse frame 1. The diameter of the air outlets 51 gradually increases, allowing the air blown out from the air outlets 51 to be more evenly distributed inside the greenhouse, thus improving ventilation efficiency.

[0035] Each blower 4 is fixedly connected to a duct 41, and one end of the duct 41 is connected to the ventilation duct 5. Air is generated by the blower 4 and guided to the ventilation duct 5 through the duct 41. Then, it is blown into the greenhouse frame 1 through the air outlet 51, thereby realizing further air flow and exchange inside the greenhouse.

[0036] The main function of the sunshade 3 is to block sunlight and reduce the temperature and light intensity inside the greenhouse. However, in rainy weather, the lower end of the sunshade 3 is tilted outwards, so rainwater will quickly flow to the edge of the sunshade 3 and be discharged outside the greenhouse, thus avoiding the risk of rainwater entering the greenhouse through gaps such as the vent 131.

[0037] In practical use, this utility model firstly, the base 11 of the greenhouse frame 1 is firmly placed on the soil. According to the environmental conditions inside the greenhouse and the growth needs of the crops, the screws 113 on both sides are rotated, which drives the slider 125 to move in the groove 112, thereby driving the insert plate 13 to slide in the slot, thereby adjusting the depth of the insert plate 13 in the slot, thus changing the exposed area of ​​the ventilation opening 131. When further ventilation is needed, the blower 4 is started. The air generated by the blower 4 is guided to the ventilation duct 5 through the duct 41. The air flows in the ventilation duct 5 and is blown evenly into the greenhouse frame 1 through the air outlet 51, realizing further air flow and exchange inside the greenhouse.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
