Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouses, in particular to a circulating ventilation type greenhouse for agriculture. Background Art

[0002] Agriculture is an industry that utilizes the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The labor object of agriculture is organisms such as plants and animals, and the obtained products come from the organisms themselves, such as silk and musk. Agriculture is a basic industry that provides support for the construction and development of the national economy; and agricultural greenhouses are relatively commonly used in agricultural planting.

[0003] The patent with the publication number of CN217850476U discloses a circulating ventilation type greenhouse for agriculture, which includes a greenhouse body. A fixed frame is fixedly connected to the top of the greenhouse body, and a ventilation opening is provided above the fixed frame on the top of the greenhouse body. A second ventilation component is provided on the fixed frame. The second ventilation component includes a cover plate adapted to the ventilation opening. The device drives the worm to rotate by driving the second motor, and then drives the worm wheel to drive the rack to rise. The rack drives the cover plate away from the ventilation opening, and the ventilation opening is opened, realizing the rapid ventilation and air exchange of the greenhouse body, eliminating the operation of manually opening and closing the ventilation opening, reducing the workload of the staff, and improving work efficiency;

[0004] However, the ventilation opening of this device is vertically downward. When the cover plate is lifted for ventilation by using structures such as the worm wheel and the second motor, the wind entering from the ventilation hole will be directly transported downward and blocked by the fixed frame, resulting in the difficulty of the entering wind to quickly transport to both sides of the greenhouse after entering the greenhouse, thus affecting the ventilation efficiency. Therefore, a circulating ventilation type greenhouse for agriculture is proposed to solve the problem that it is difficult to quickly ventilate the interior of the existing agricultural greenhouse.

[0026] Furthermore, there is a certain distance between the rain shelter ceiling 3 and the top of the greenhouse main body 1. The rain shelter ceiling 3 is larger than the ventilation opening 2. The vertical plates 14 are fixedly connected to the lifting plate 9. During ventilation, the rain shelter ceiling 3 can be used to achieve ventilation on rainy days. After ventilation, the electric push rod 8 is used to drive the lifting plate 9 to move downward and reset. Then, in cooperation with the vertical plates 14, the rain shelter ceiling 3 moves downward to fit with the top of the greenhouse main body 1, thereby blocking the ventilation opening and ensuring the airtightness of the greenhouse to prevent rainwater or impurities from entering.

[0027] Furthermore, the electric push rod 8 penetrates through the fixed seat 6 and is fixedly connected to the lifting plate 9. The guide wind plates 10 are movably connected to the top of the fixed seat 6.

[0028] Furthermore, the water collecting and adjusting mechanism 12 includes water collecting hoppers 121 fixedly connected to both sides of the upper position of the greenhouse main body 1. A water tank 122 is arranged at one end of the greenhouse main body 1. A heating pipe 128 is arranged at the bottom of the inner cavity of the water tank 122. A water inlet pipe 125 is arranged on one side of the water collecting hopper 121. The water inlet pipe 125 communicates with the water tank 122.

The connecting pipes 124 communicate with both the water pump 123 and the water guide pipe 126. The rainwater can be introduced into the water tank 122 for collection through the cooperation of the water collecting hopper 121 and the water inlet pipe 125. If the temperature inside the greenhouse main body 1 is relatively high due to hot weather, the water in the water tank 122 can be pumped into the water guide pipe 126 inside the water collecting hopper 121 by the water pump 123, and then the water is sprayed onto the outer wall of the greenhouse main body 1 by the water guide nozzles 127 to isolate the external heat and play a role in cooling the inside of the greenhouse. When the weather is relatively cold, the heating pipe 128 is used to heat the water tank 122, and the above process is repeated to spray hot water onto the outer wall of the greenhouse main body 1 to play a certain heat preservation role and improve the practicability of this agricultural circulating ventilation greenhouse.

After the ventilation is over, the electric push rod 8 drives the lifting plate 9 to move down and reset, and cooperates with the vertical plate 14, and the rain shelter 3 moves down to fit with the top of the greenhouse main body 1, thereby blocking the ventilation opening and ensuring the airtightness of the greenhouse to prevent rainwater or impurities from entering.
