Description

Technical Field

[0001] The utility model relates to the technical field of irrigation devices, and particularly relates to a greenhouse irrigation device. Background Art

[0002] Peppers are annual or limited perennial herbaceous plants, with many processed products, a long industrial chain, and high added value. They are important industrial raw material crops, so they have become the vegetable with the largest planting area in China in greenhouse cultivation.

[0003] During the process of growing peppers in greenhouses, it is found that peppers are greatly affected by irrigation water. Both too high or too low humidity will directly affect the yield of pepper crops. Different from the natural planting environment in greenhouses, the internal environment needs to be manually regulated; Manual pipe irrigation lacks scientificity and accuracy, requires high irrigation experience, may lead to waste of water resources, and even have a negative impact on the environment and crops.

[0004] In summary, considering designing a device for irrigation to reduce water resource waste and provide irrigation needs more scientifically and accurately; In view of this, we propose a greenhouse irrigation device. Content of the Utility Model

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The greenhouse irrigation device is connected with a plurality of drip irrigation branch pipes and spraying components through an irrigation pipeline. The drip irrigation branch pipes can perform fixed-point drip irrigation on the roots of crops, reducing water resource waste caused by large-scale irrigation. At the same time, the provided spraying components can spray atomized water into the greenhouse environment, which is beneficial to quickly adjusting the temperature and humidity inside the greenhouse and maintaining a stable crop planting environment. The device can cooperate with multiple sensors and realize scientific irrigation based on a control system;

The diversion pipe 34 is vertically installed on the vertical fixing frame 1 through a fixed clamping ring 2. A shunt pipe 32 is conductively installed between the water inlet pipe 31 and the diversion pipe 34, and a first valve 33 is installed on the shunt pipe 32; a plurality of second valve pipes 36 are evenly distributed on the bottom pipe 35, and the drip irrigation branch pipe 4 is detachably installed on the second valve pipe 36. A drip irrigation emitter corresponding to the crop is installed on the drip irrigation branch pipe 4. The drip irrigation branch pipe 4 in this embodiment is used to drip water and fertilizer to the roots of the crop, providing a more accurate directional irrigation site.

A convex-shaped sprinkler pipe 54 is installed on the I-shaped bottom frame 52, and a plurality of atomizing nozzles 55 for spraying water into the greenhouse air are installed on the sprinkler pipe 54. The water inlet end of the sprinkler pipe 54 is conductively connected to the first valve 33 through a hose; it should be noted that the sprinkler pipe 54 adopts as Figure 5The convex structure shown can form a fan-shaped dispersion structure when spraying atomized irrigation water, enabling a larger spray range in the air. In this embodiment, the spraying assembly 5 sprays water into the air in the greenhouse, aiming to quickly regulate the temperature and environmental humidity inside the greenhouse, avoid the problem of crop stems and leaves being damaged by the high-temperature and scorching environment, and this structure can avoid excessive water resource waste.
