Examples

As shown in fig. 1, an irrigation device for a vegetable planting greenhouse comprises a greenhouse frame 10 arranged on a dome, a partition 11 is arranged on the top of the inner side of the frame 10, a water spray pipe 20 in an L shape is arranged in the center of the partition 11, the transverse part of the water spray pipe 20 is positioned below the partition 11, the top end of the longitudinal part of the water spray pipe 20 extends to the upper part of the partition 11 through the partition 11, a bearing 12 is arranged between the longitudinal part of the water spray pipe 20 and the partition 11, and a plurality of nozzles 21 are arranged on the side wall of the transverse part of the water spray pipe 20 at equal intervals along the axial direction of the transverse part; a water tank 30 is arranged outside the greenhouse, the water tank 30 is connected with a water conveying pipeline 32 through a water pump 31, and the water conveying pipeline 32 is connected with the top end of the longitudinal part of the water spraying pipe 20 in a rotating and sealing mode; a circle of water collecting grooves 13 are formed in the periphery of the dome, the water collecting grooves 13 are obliquely arranged, the lowest position of each water collecting groove 13 is located right above the water tank 30, a drain hole 14 is formed in the lowest position of each water collecting groove 13, a water collecting hopper 33 is arranged below the drain hole 14, and the water collecting hopper 33 is arranged at the top of the water tank 30.

When watering is needed, water in the water tank 30 is delivered to the water spraying pipe 20 through the water delivery pipe 32 by the water pump 31, the water is sprayed out from each nozzle 21, and the nozzles 21 are all arranged obliquely below the transverse part of the water spraying pipe 20, when the nozzles 21 spray water, a horizontal reaction force is given to the transverse part of the water spraying pipe 20, and the transverse part of the water spraying pipe 20 rotates around the longitudinal part of the water spraying pipe 20 as an axis under the drive of the reaction force, so that all the vegetables in the greenhouse are watered. By using the reaction force when the nozzle 21 sprays water, the spray pipe 20 can rotate without additionally configuring a rotating motor, and the cost and the failure rate are greatly reduced.

Rainwater can be collected to the water tank 30 through the water collecting tank 13 and the water collecting hopper 33 for irrigation, and water resources are saved. The inclined arrangement of the water collecting tank 13 can facilitate the concentrated rainwater to be drained into the water tank 30 completely.

In one embodiment, a plurality of the nozzles 21 are provided with a plurality of water jet holes, and the diameter of the water jet holes of the plurality of nozzles 21 gradually increases from a longitudinal portion near the water jet pipe 20 to a direction away from the longitudinal portion.

The more distant the nozzle 21 from the longitudinal portion, the larger the area to be irrigated and the more water is naturally required due to the larger turning radius, so the more distant the nozzle 21 from the longitudinal portion, the larger the hole diameter of the water jet hole.

In one embodiment, a relief valve 22 is respectively arranged between every two adjacent nozzles 21 in the transverse part of the sprinkler pipe 20, and the opening pressure of each relief valve 22 is gradually increased from the longitudinal part close to the sprinkler pipe 20 to the direction far away from the longitudinal part; a booster valve 34 is arranged on the water pipe 32 near the connection part of the water pipe and the water spraying pipe 20.

Because the planting area in the greenhouse may be different according to market demands, in some cases, the whole greenhouse may not need to be watered, and the cooperation of the overflow valve 22 and the pressure increasing valve 34 is adopted, so that when the planting area is small or only an area close to the center needs to be watered, a small water pressure can be used, and only the nozzle 21 close to the longitudinal part is communicated with the water conveying pipeline 32 for watering; when the planting area is large or the large area is irrigated, larger water pressure can be used, so that more nozzles 21 are communicated with the water pipeline 32 for irrigation.

In one embodiment, the bottom of the water collecting hopper 33 is provided with a filter screen 35 detachably connected with the water collecting hopper 33.

All contain partial impurity in the rainwater usually, filter impurity through filter screen 35, can avoid the impurity in the rainwater to cause the jam to the pipeline. The filter screen 35 is detachably connected with the water collecting hopper 33, so that the filter screen 35 can be replaced conveniently.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
