Description

Technical Field

[0001] This utility model relates to the field of greenhouses, specifically a watermelon greenhouse with adjustable temperature and humidity. Background Technology

[0002] In traditional watermelon cultivation, greenhouses are typically built to control temperature and humidity in order to ensure a suitable environment for watermelon growth. However, the temperature and humidity regulation in traditional greenhouses mainly relies on manual operation, such as opening and closing vents and spraying water. This is not only cumbersome to operate, but also has limited regulatory effect, making it difficult to meet the precise needs of watermelon growth, thus affecting the quality and yield of watermelons.

[0003] A search revealed a watermelon cultivation greenhouse with publication number CN205962052U. This greenhouse uses vine-guiding poles to encourage watermelon vine growth, and suspends the growing watermelons in the air using nets to ensure they receive adequate sunlight and reduce the chance of pests and diseases. By using plant growth lights to periodically illuminate the watermelons, supplemental light is provided, promoting fruit setting and nutrient absorption, and increasing the sugar content and quality of the watermelons.

[0004] While the watermelon greenhouse can provide some protection and insulation, it is difficult to regulate the temperature, which is inconvenient to use. Furthermore, its irrigation efficiency is low, which can easily lead to waste. Utility Model Content

[0005] To address the existing problems, this utility model provides a watermelon greenhouse with adjustable temperature and humidity, thereby solving the problems mentioned in the background art, such as the difficulty in regulating temperature, low irrigation efficiency, and easy waste caused by the greenhouse.

[0006] To address the aforementioned problems, this utility model provides a watermelon greenhouse with adjustable temperature and humidity, comprising a main wall, with a set of greenhouse side walls symmetrically arranged on both sides of the main wall, a keel set on the side of the greenhouse side wall away from the main wall, the keel covered with a film greenhouse body, a cold-proof blanket rolling device set at the top of the greenhouse side wall, and an irrigation device and a drainage device set inside the main wall and the greenhouse side walls; the irrigation device includes a water tank, with several water outlet pipes connected to the lower side of the water tank, a water outlet valve set at the connection between the water outlet pipes and the water tank, several capillary drippers arranged sequentially on the upper side of the water outlet pipes, and a set of water tank supports symmetrically arranged at both ends of the lower side of the water tank; the drainage device includes several drainage channels, with several drainage outlets arranged sequentially at the bottom of the drainage channels, and drainage pipes connected to the lower ends of the drainage outlets, and several drainage pipes connected together to a main drainage pipe.

[0007] Furthermore, the cold-proof blanket winding device includes a motor, the output end of which is connected to a winding roller, the winding roller is fixedly connected to one side of the cold-proof blanket, a winding drum is installed on the outer side of the winding roller and the cold-proof blanket, and a counterweight bar is provided on the other side of the cold-proof blanket.

[0008] Furthermore, ventilation holes are provided on the side wall of the greenhouse, and ventilation fans are installed on the ventilation holes.

[0009] Furthermore, a cold-proof groove is provided on the outer side of the keel.

[0010] Furthermore, a filter screen is provided at the connection between the drainage ditch and the drainage outlet.

[0011] Furthermore, the main drain pipe can be connected to the farm's drainage system or discharged directly into the frost protection ditch.

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

[0013] 1. Strong temperature and humidity regulation capability: The installed frost protection blanket rewinding device can effectively regulate the temperature inside the greenhouse by rolling up or lowering the blanket via a motor-driven roller, based on changes in the outside temperature. Simultaneously, the ventilation holes and fans on the greenhouse side walls further regulate humidity and air circulation, providing a more suitable growing environment for the watermelons.

[0014] 2. High-efficiency water-saving irrigation: The design of the irrigation device, especially the use of capillary drippers, allows for precise control of the irrigation water volume, directly targeting the watermelon roots, greatly improving irrigation efficiency and reducing water waste. The outlet valves allow for flexible control of the opening and closing of each outlet pipe, adjusting the irrigation area according to actual needs.

[0015] 3. Comprehensive Drainage System: The drainage system, including drainage ditches, outlets, pipes, and a main drain, ensures that excess water can be drained promptly during heavy rains or over-irrigation, preventing waterlogging from negatively impacting watermelon growth. Filter screens also prevent debris from clogging the outlets, keeping the drainage system unobstructed. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 A watermelon greenhouse with adjustable temperature and humidity includes a main wall 1, with a set of greenhouse side walls 2 symmetrically arranged on both sides of the main wall 1. A keel 3 is installed on the side of the greenhouse side wall 2 away from the main wall 1, and the keel 3 is covered with a plastic film greenhouse body 4. A cold-proof blanket retracting device 5 is installed at the top of the greenhouse side wall 2. An irrigation device 6 and a drainage device 7 are installed inside the main wall 1 and the greenhouse side walls 2. The irrigation device 6 includes a water tank 601, and several water outlet pipes 602 are connected to the lower side of the water tank 601. A water outlet valve 603 is provided at the connection between the water outlet pipe 602 and the water tank 601. Several capillary drippers 604 are arranged sequentially on the upper side of the water outlet pipe 602. A set of water tank supports 605 are symmetrically arranged at both ends of the lower side of the water tank 601. The drainage device 7 includes several drainage channels 701. Several drain outlets 702 are arranged sequentially at the bottom of the drainage channels 701. The lower end of the drain outlets 702 is connected to a drain pipe 703. Several drain pipes 703 are connected to a main drainage pipe 704.

[0025] By adopting the above technical solutions, the design of the irrigation device 6, especially the use of the capillary dripper 604, can precisely control the irrigation water volume, directly acting on the watermelon roots, greatly improving irrigation efficiency and reducing water waste. The outlet valve 603 can flexibly control the opening and closing of each outlet pipe 602, adjusting the irrigation area according to actual needs.

[0026] The cold-proof blanket winding device 5 includes a motor 501, and a winding roller 502 is driven and connected to the output end of the motor. The winding roller 502 is fixedly connected to one side of the cold-proof blanket 503. A winding drum 504 is installed on the outside of the winding roller 502 and the cold-proof blanket 503. A counterweight rod 505 is provided on the other side of the cold-proof blanket 503.

[0027] By adopting the above technical solution, the frost protection blanket winding device 5 can effectively regulate the temperature inside the greenhouse by driving the winding roller 502 to roll up or unroll the frost protection blanket 503 according to changes in the outside temperature through the motor 501. At the same time, the ventilation holes 8 and ventilation fans on the greenhouse side wall 2 can further regulate the humidity and air circulation inside the greenhouse, providing a more suitable growing environment for watermelons.

[0028] Ventilation holes 8 are provided on the side wall 2 of the greenhouse, and ventilation fans are installed on the ventilation holes 8.

[0029] The outer side of the keel 3 is provided with a cold-proof groove 9.

[0030] A filter screen is provided at the connection between the drainage ditch 701 and the drainage outlet 702.

[0031] The main drainage pipe 704 can be connected to the farm's drainage system or discharged directly into the frost protection ditch 9.

[0032] By adopting the above technical solution, the drainage device 7, including the drainage ditch 701, drainage outlet 802, drainage pipe 703, and main drainage pipe 704, ensures that excess water can be discharged in time during heavy rain or excessive irrigation, avoiding the adverse effects of waterlogging on watermelon growth. The filter screen also prevents debris from clogging the drainage outlet, keeping the drainage system unobstructed.

[0033] Specific embodiments of this utility model:

[0034] Under the condition that the greenhouse is closed in winter, there is no problem with the watermelons overwintering. However, at night, the frost protection blanket 504 needs to be lowered in advance. When the temperature drops suddenly, the control motor 501 rotates to drive the winding roller 502 to rotate inside the winding drum 504. The rotation of the winding roller 502 lowers the frost protection blanket 503 on the surface, thus covering the greenhouse and providing insulation. When the temperature inside the greenhouse is too high, the motor 501 rotates in the opposite direction to drive the winding roller 502 to roll up the frost protection blanket 503, thereby lowering the temperature.

[0035] When cultivating watermelons in this greenhouse, the ventilation holes 8 on the greenhouse need to be closed during the first and second overwintering years after the watermelon seedlings are planted; from the third overwintering year onwards, the ventilation holes 8 no longer need to be closed for overwintering management.

[0036] Inside this greenhouse, there are multiple water outlet pipes 602 connected to the lower end of the water tank 601 to extend the water in the water tank 601 outward. The specific structure of the water outlet pipe 602 includes a water outlet valve 603 and a capillary dripper 604. When the water outlet valve 603 is opened, the water flows from the water tank 601 along the water outlet pipe 602 into the capillary dripper 604 and slowly flows out from the capillary dripper 604. Several drainage outlets 702 are arranged sequentially at the bottom of the drainage ditch 701. The lower end of the drainage outlet 702 is connected to the drainage pipe 703. Several drainage pipes 703 are connected to the main drainage pipe 704. Excess water after a thorough watering enters the drainage outlet 702 through the drainage ditch 701 and is discharged through the main drainage pipe 704. For watermelon irrigation, after planting, the water is thoroughly watered through the irrigation device 6. Excess water needs to be discharged through the drainage device 7. After the watermelons have established themselves, watering needs to be strictly controlled, 3-4 times per growing season.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
