Description

Technical Field

[0001] This application relates to the field of planting equipment, and in particular to an irrigation system for blueberry greenhouses. Background Technology

[0002] Existing large-scale blueberry production generally relies on greenhouse cultivation, where temperature, humidity, and light are artificially controlled to create a more suitable growing environment for the blueberry bushes. In actual cultivation, it has been found that timely water control and fertilization have a significant impact on blueberry quality. However, greenhouse irrigation still relies on traditional manual methods, which are labor-intensive, wasteful of water resources, and severely limit the improvement of greenhouse crop yield and quality. CN216452241U discloses a greenhouse circulating irrigation system that requires multiple sprinklers fixed at the bottom of the greenhouse for irrigation. However, the sprinkler positions are fixed and low during irrigation, making it impossible to cover the different growth stages of blueberry seedlings, resulting in low irrigation efficiency.

Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Current large-scale blueberry production typically utilizes greenhouse cultivation. Blueberries have high soil requirements; excessive watering or insufficient fertilization can negatively impact fruit set. Therefore, it's necessary to artificially regulate the blueberry growing environment to create a more suitable growing conditions for the seedlings. Generally, multiple sprinklers are fixed at the bottom of the greenhouse or at the base of the seedlings for irrigation. However, during irrigation, the fixed sprinkler positions and low installation height, coupled with the significant height difference of blueberry seedlings at different growth stages (up to 2 meters, and sometimes approaching 3 meters), prevents the fixed sprinklers from flexibly adjusting the spray height according to plant growth. Furthermore, if the sprinkler system is only fixed to the greenhouse roof, plants on the outer edges of the seedlings can obstruct water flow, resulting in uneven irrigation and failing to provide adequate watering and fertilization for different growth stages, thus affecting fruit set.

[0024] Based on the above, the following will combine... Figures 1 to 4 The embodiments of this utility model are described below.

[0025] This application provides a blueberry greenhouse irrigation system, which includes a greenhouse frame 100, an upper sprinkler assembly 200, a lower irrigation assembly 300, and a water supply assembly; the upper sprinkler assembly 200 is disposed inside the greenhouse frame 100 and located at the top of the greenhouse frame 100; the lower irrigation assembly 300 is disposed inside the greenhouse frame 100 and located at the bottom of the greenhouse frame 100; the water supply assembly is connected to the upper sprinkler assembly 200 and the lower irrigation assembly 300 respectively, and is used to supply water to the upper sprinkler assembly 200 and the lower irrigation assembly 300.

[0026] The water supply assembly is connected to the upper sprinkler assembly 200 and the lower irrigation assembly 300 through pipelines, so that water flows into the sprinkler head of the upper sprinkler assembly 200 and the sprinkler pipe 320 of the lower irrigation assembly 300 respectively. The upper sprinkler assembly 200 covers the top area, and the lower irrigation assembly 300 targets the bottom crop roots, so as to achieve bidirectional irrigation from top to bottom. The coverage is more comprehensive when spraying. Bidirectional irrigation can simultaneously meet the water needs of blueberry crop leaves and roots, improve the spraying efficiency, and eliminate the need to fix a large number of sprinkler heads.

[0027] In some embodiments, the upper sprinkler assembly 200 includes a base 211, a guide rail 213, guide wheels 214, a connecting rod 215, and a drive device 216. A sprinkler bracket 212 is fixed on the base 211, and a plurality of sprinkler heads are provided on the sprinkler bracket 212. The sprinkler heads are connected to the water supply assembly. The guide rail 213 is located inside the shed 100 and at the top of the shed 100. Guide wheels 214 are respectively provided on both sides of the base 211. The two guide wheels 214 are connected by the connecting rod 215. The guide rail 213 cooperates with the guide wheels 214. The drive device 216 is connected to the guide wheels 214 to drive the guide wheels 214 to move along the length direction of the guide rail 213.

[0028] In some embodiments, the drive device 216 includes a drive wheel 2161, a driven wheel 2162, a transmission belt 2163, and a motor 2164. The motor is fixed to one side of the base 211. The drive wheel 2161 is connected to the output shaft of the motor 2164. A transmission rod is provided on the outer side of the guide wheel 214. The driven wheel 2162 is fixed to one end of the transmission rod. The drive wheel 2161 and the driven wheel 2162 are connected by the transmission belt 2163. Thus, when the motor 2164 starts, it drives the drive wheel 2161 to rotate, which in turn drives the driven wheel 2162 and the guide wheel 214 to rotate via the transmission belt 2163. This causes the base 211 to reciprocate along the guide rail 213. As the base 211 moves, the sprinkler heads 218 on the sprinkler bracket 212 move synchronously, spraying water evenly downwards. The sprinkler head 218 is moved laterally on the top of the greenhouse to achieve dynamic spraying, while also expanding the spraying range and reducing the number and density of fixed sprinklers on the support of the upper sprinkler assembly 200.

[0029] Furthermore, the base 211 is provided with a limiting guide wheel 217 at its top, and the frame 100 is provided with a limiting slide groove, which is located above the guide rail 213. The limiting guide wheel 217 is connected to the limiting slide groove. Thus, the cooperation between the limiting guide wheel 217 and the limiting slide groove ensures that the base 211 moves smoothly, preventing the base 211 from shifting or derailing, and further improving the stability of the sprinkler bracket 212 during spraying.

[0030] In some embodiments, the upper sprinkler assembly 200 includes a drive motor 222, a transmission shaft 223, a traction rope 224, and a sprinkler frame 225. The drive motor 222 is fixed to the shed 100. The transmission shaft 223 is arranged laterally and connected to the output shaft of the drive motor 222. One end of the traction rope 224 is fixed and wound around the transmission shaft 223, and the other end of the traction rope 224 is fixed to the sprinkler frame 225. The sprinkler frame 225 is provided with a plurality of nozzles 226, and the nozzles 226 are in communication with the water supply assembly.

[0031] When the motor rotates forward, the drive shaft 223 winds the traction rope 224, pulling the sprinkler frame 225 to one side; when the motor rotates in reverse, the traction rope 224 is released, and the sprinkler frame 225 moves in the opposite direction. Thus, by driving the motor 222 to raise and lower the traction rope 224, the height of the sprinkler frame 225 can be adjusted to spray water at close range above the blueberry crops. After irrigation, it is raised back to the top to avoid blocking sunlight and reduce humidity inside the greenhouse.

[0032] In some embodiments, multiple baffles 227 are spaced apart along the length of the drive shaft 223, and multiple traction ropes 224 are provided, each traction rope 224 being positioned between two adjacent baffles 227. The baffles 227 are fixed to the drive shaft 223, separating the traction ropes 224. Multiple traction ropes 224 are connected to the spray frame 225, driving it to move up and down, so that the traction ropes 224 do not tangle with each other, thereby enabling multiple traction ropes 224 to work synchronously, ensuring the smooth movement of the spray frame 225 and preventing tilting.

[0033] In some embodiments, the irrigation assembly 300 includes branch pipes 310 and spray pipes 320, and there are multiple branch pipes 310 and spray pipes 320. The multiple branch pipes 310 are spaced apart along the length direction of the bottom of the shed 100, and each branch pipe 310 is provided with multiple spray pipes 320.

[0034] In relevant technical solutions, surface irrigation often involves uniformly distributing pipes without considering the environmental differences between the greenhouse edges and the center. During actual irrigation, the soil on the sides of the greenhouse near the frame 100 experiences higher moisture levels due to greater water infiltration from outside the greenhouse and the dripping of water droplets from the greenhouse film, resulting in significantly higher soil moisture in the outer areas compared to the central area. Since dry and humid areas have different water requirements, and the soil moisture within the greenhouse is unevenly distributed, this uneven soil moisture distribution will be further exacerbated if a uniform irrigation method is applied without differentiation, leading to significant differences in seedling growth across different areas. Therefore, in some embodiments, the interval between adjacent branch pipes gradually decreases from the outer edge of the frame 100 inwards; that is, the closer to the outer edge of the frame, the larger the interval between branch pipes. This differentiated interval setting optimizes water resource allocation to address the differences in soil moisture and water requirements in different areas.

[0035] In some embodiments, a fertilizer supply component is further included, comprising a fertilizer pump, a fertilizer solution tank, and a valve. The inlet of the fertilizer pump is connected to the fertilizer solution tank, and the outlet of the fertilizer pump is connected to the water supply component. The valve is located on the pipeline between the fertilizer pump and the fertilizer solution tank to adjust the fertilizer concentration to meet the needs of crops at different growth stages. In this way, the fertilizer pump draws the nutrient solution from the fertilizer tank into the water supply pipeline, mixes it with irrigation water, and then applies the fertilizer simultaneously through upper and lower sprinkler systems, achieving integrated water and fertilizer management without the need for manual fertilization in the greenhouse or additional fertilizer supply devices. For example, topdressing is required, with controlled watering and the application of a low-concentration high-phosphorus fertilizer, such as approximately 0.5% potassium dihydrogen phosphate, combined with a long-acting potassium sulfate compound fertilizer, to encourage the blueberry seedlings to form more calyxes and increase the fruit set rate.

[0036] In some embodiments, the water supply assembly includes a water storage tank, a water pump, a one-way valve, and a filter. The inlet of the water pump is connected to the water storage tank, the outlet of the water pump is connected to the filter, and the one-way valve is located on the outlet pipe of the filter.

[0037] Optionally, the filter includes a sand filter and a disc filter. During operation, the suction pump starts, drawing liquid from the storage tank and sending it through the inlet pipe to the sand filter to remove large particles. It then enters the disc filter for further filtration of finer impurities, before flowing through a one-way valve into the upper and lower sprinkler components to supply water to them. This multi-stage filtration prevents clogging of the sprinkler heads and pipes, extending the lifespan of the upper and lower sprinkler systems.

[0038] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present disclosure.
