Description

Technical Field

[0001] The present invention relates to the technical field of watering and irrigation for greenhouse planting, and particularly to an intelligent sprinkler irrigation system for vegetable planting greenhouses. Background Art

[0002] A vegetable greenhouse is a framed film-covered structure with excellent heat preservation performance. Its emergence enables people to eat out-of-season vegetables. Generally, bamboo structures or steel structures are used as the skeletons of vegetable greenhouses, and one or more layers of heat-preserving plastic films are covered on them, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide generated by the growth of internal vegetables, making the greenhouse have a good heat preservation effect.

[0003] The construction process of vegetable greenhouses is relatively simple, but the technology is relatively delicate. The vegetable supply in our country mainly relies on vegetable greenhouse planting. Therefore, the construction quality and design structure of vegetable greenhouses directly affect the yield and quality of vegetables in our country.

[0004] Structurally speaking, vegetable greenhouses mainly include load-bearing walls, structural steel frames, support columns, arched roofs, and plastic outer films, etc.; in terms of supporting facilities, modern greenhouse greenhouses usually include planting troughs, sprinkler irrigation systems, temperature control systems, auxiliary lighting systems, and humidity control systems. The planting troughs are set at the bottom of the windows or made into partition screens for planting vegetables; the sprinkler irrigation system automatically supplies water in due time and in appropriate amounts; the temperature control system includes exhaust fans, hot fans, temperature sensors, and a constant temperature system control box to adjust the temperature in due time; the auxiliary lighting system includes plant lights and reflectors, which are installed around the planting troughs to provide lighting when there is no sunlight, enabling plants to carry out photosynthesis; the humidity control system cooperates with the exhaust fan to adjust the humidity and reduce the indoor temperature.

[0005] Specifically for the irrigation of greenhouse vegetables, its main purpose is to ensure that greenhouse vegetables can obtain appropriate and sufficient water in different growth cycles through reasonable watering, so as to promote the healthy growth of vegetable crops and improve the crop yield. Therefore, the rationality of the design of the sprinkler irrigation system will directly affect the final yield and quality of vegetable crops.

[0006] However, most existing vegetable greenhouses adopt traditional manual sprinkler irrigation methods. Due to their own limitations, when applied on a large scale, there are often many problems, including: 1. The sprinkler irrigation method is single, and the parameters during the sprinkler irrigation process are not easy to adjust, making it difficult to achieve adaptive sprinkler irrigation for different types of vegetables in different growth cycles.

[0007] 2. The degree of automation of sprinkler irrigation is low. The control of the sprinkler irrigation water volume requires a large amount of manual participation, and restricted by the laying of water pipes, it can often only achieve fixed-point sprinkler irrigation and cannot cover all vegetables, resulting in easy omission of sprinkler irrigation dead spots during the overall sprinkler irrigation process, affecting the sprinkler irrigation effect.

[0008] 3. During the irrigation process, due to the long conveying distance, it is easy to cause untimely replenishment of irrigation water, resulting in uneven sprinkler irrigation.

[0009] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0046] When the present invention is in use: First, the rainwater collection tank 4 is used to recycle rainwater, and sundries are isolated by the isolation screen 5. The rainwater slides down along the outer film of the greenhouse and is stopped by the arc buffer baffle 6. When there is sufficient rainwater in the rainwater collection tank 4, the three-way valve 10 is opened, and the rainwater enters the transfer water pipe 11 from the rainwater collection tank 4 through the water pipe 9, and then supplies the supplementary water supply pump 12. When the rainwater in the rainwater collection tank 4 is insufficient, the conveying water pump 7 is started, and the conveying water pump 7 lifts the irrigation water along the water pipe 8 to the transfer water pipe 11 and also enters the supplementary water supply pump 12. In the initial state, the water supply pipe 13 and the water inlet pipe 28 are in a butted state. At the same time, the supplementary water supply pump 12 and the water inlet check valve 29 are opened to inject the irrigation water into the follow-up water storage tank 25. The water in the follow-up water storage tank 25 then enters the shunt box 26 through the corrugated pipe 27 and is then shunted to the fixed sprinkler pipe 32 and the rotating sprinkler pipe 33. At the same time, two sliding drive motors 15 are started. The sliding drive motors 15 drive the threaded drive rod 16 to rotate, thereby driving the sliding clamping seat 17 to slide horizontally along the limit slide rail 14. Two double-output shaft motors 21 are respectively started. The two double-output shaft motors 21 drive the four drive rollers 22 to rotate, thereby driving the fixed end cover 19, the horizontal support plate 20, and the square steering seat 24 to slide longitudinally along the two support guide beams 18. Through the superposition of the horizontal and vertical movements, the sprinkler irrigation can cover all areas inside the greenhouse. The transmission drive motor 34 is started. The transmission drive motor 34 drives the transmission wheel 35 to rotate. Through the transmission action of the transmission snap ring 36, the rotating sprinkler pipe 33 is driven to rotate around the axis. The fixed three-nozzle 37 is opened to realize rotary sprinkler irrigation. The rotation motor 38 is started. The rotation motor 38 drives the rotating three-nozzle 39 to rotate to realize circumferential sprinkler irrigation. The steering drive motor 23 is started. The steering drive motor 23 drives the square steering seat 24 to rotate, and the switching between the two sprinkler irrigation methods of rotary sprinkler irrigation and circumferential sprinkler irrigation can be realized, and the sprinkler irrigation range can be increased by steering. Further, by controlling the lifting and telescoping, the shunt box 26, the fixed sprinkler pipe 32, and the rotating sprinkler pipe 33 can be controlled to lift, so as to adjust the sprinkler irrigation height.
