Description

Technical Field

[0001] This utility model relates to the field of cut flower planting technology, specifically to a rainwater harvesting type drip irrigation component for planting sheds. Background Technology

[0002] Fresh-cut flowers refer to the stems, leaves, flowers, fruits, and other plant materials cut from living plants that have ornamental value and are used to make flower baskets, bouquets, wreaths, vase arrangements, wall decorations, and corsages. Fresh-cut flowers usually need to be grown inside a greenhouse, and drip irrigation is required during the growing process.

[0003] Patent CN220831171U discloses a drip irrigation device for tea cultivation, including a fixed frame. A water-passing plate is fixedly connected above the fixed frame at both ends. A limiting plate is fixedly connected between the fixed frames at both ends below the water-passing plate. A slider is slidably connected between the limiting plate and the water-passing plate. A movable box is fixedly connected to the front side of the slider. Several water-passing holes are opened on the front side of the water-passing plate. The interior of the water-passing plate has a hollow structure. A telescopic rod is fixedly connected to one side of the interior of the water-passing plate at the position corresponding to the position of the water-passing hole. A baffle is provided on the other side of the interior of the water-passing plate at the position corresponding to the position of the water-passing hole. A connecting plate is provided on one side of the upper end of the movable box.

[0004] Although the device, equipped with a water-passing plate, telescopic rod, second spring, baffle, water-passing hole, slider, screw, moving box, water-passing pipe, connecting plate, and first spring, facilitates adjusting the dripper position according to the growth of tea trees, it lacks a structure for adjusting the height of multiple drippers. This means it cannot adjust the height of multiple drippers according to the growth of cut flower plants, thus failing to ensure that water droplets accurately reach the crop root zone, resulting in uneven irrigation. Furthermore, in dry and hot climates, it does not reduce the time and area of ​​water droplets exposed to air, increasing water evaporation loss and wasting water resources. Additionally, the device cannot be moved while drip irrigation is being performed, making its applicability limited. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-9This utility model provides a technical solution: a rainwater harvesting type drip irrigation component for a planting shed, including a drip irrigation mechanism 7 and a shed body 1. The drip irrigation mechanism 7 is disposed between the inner walls of the left and right sides of the shed body 1. A door 2 is embedded on the left side surface of the shed body 1 and hinged thereto by two hinges. The drip irrigation mechanism 7 includes two rotating columns 71 that are rotatably connected to the inner walls of the left and right sides of the shed body 1 respectively, a screw 72 that is coaxially fixed between the two rotating columns 71 and located inside the shed body 1, and a screw 72 that is slidably connected to the inner top surface of the shed body 1 and connected to the screw 72. The components include: a threaded movable block 73; a mounting plate 75 fixed to the bottom surface of the movable block 73; an electric cylinder 76 with its cylinder body mounted on the bottom surface of the mounting plate 75; a water box 78 fixed to the piston rod of the electric cylinder 76 via a gasket 77; several drip irrigation heads 79 fixed to the bottom surface of the water box 78 and connected to its inner cavity; an outlet pipe 710 fixed to the left side surface of the water box 78 and connected to its inner cavity; and an inlet pipe 711 fixed to the left side surface of the shed body 1 and connected to its inner cavity. A water outlet pipe 710 extends through the left side surface of the greenhouse 1 and into the interior of the greenhouse 1 near the left end. The water outlet pipe 710 is connected to the water inlet pipe 711 via a corrugated pipe 712. The drip irrigation mechanism 7 also includes a rotating rod 714 coaxially fixed on the surface of one of the rotating columns 71 away from the screw 72, and a motor 716 installed on the outer wall of the greenhouse 1 to drive the rotating rod 714 to rotate. It should be added that a handle 3 is installed on the left side surface of the door 2. By setting up the drip irrigation mechanism 7, the fresh cut flower plants inside the greenhouse 1 can be drip irrigated. The design of the drip irrigation mechanism 7 allows several drip irrigation heads 79 to move while drip irrigating the fresh cut flowers. The design of the drip irrigation mechanism 7 also facilitates the adjustment of the height of several drip irrigation heads 79, so that the height of several drip irrigation heads 79 can be adjusted according to the height of the fresh cut flower plants. At the same time, it can also reduce the time and area of ​​water droplets exposed to the air, thereby reducing water evaporation loss and thus achieving the effect of saving water resources.

[0031] In this embodiment, a guide groove is provided on the inner top surface of the shed body 1, and a guide block 74 is fixed on the top surface of the moving block 73 and slidably connected to the guide groove on the inner top surface of the shed body 1. This can guide the movement of the moving block 73, and thus indirectly guide the movement of several drip irrigation heads 79.

[0032] In addition, the width of the water box 78 is matched with the inner width of the greenhouse 1, and the several drip irrigation heads 79 on the bottom surface of the water box 78 are arranged in a linear and equidistant manner, which can smoothly drip irrigate the cut flower plants inside the greenhouse 1.

[0033] Furthermore, the drip irrigation mechanism 7 also includes two gears 715 located outside the greenhouse 1 and meshing with each other, and a rotating shaft 717 coaxially connected to the output shaft of the motor 716. The two gears 715 are respectively coaxially fixed on the outer circumference of the rotating shaft 717 and the rotating rod 714, which can smoothly drive the rotating rod 714 to rotate, and thus smoothly drive the screw 72 to rotate.

[0034] Furthermore, a collection box 4 is fixed on the top surface of the shed 1. A filter screen 5 with a cavity size that is adapted to the inside of the collection box 4 is installed near the top. The collection box 4 is connected to the water inlet pipe 711 through the water pipe 6, so that the whole device can have the function of rainwater collection.

[0035] Specifically, the longitudinal cross-sectional shape of the guide groove on the inner top surface of the shed body 1 is convex, and the shape of the guide block 74 is convex, which matches the shape of the guide groove on the inner top surface of the shed body 1. This makes the connection between the guide block 74 and the guide groove on the inner top surface of the shed body 1 tighter, thereby indirectly making the water box 78 and several drip irrigation heads 79 more stable during movement.

[0036] It is worth noting that the drip irrigation mechanism 7 also includes a protective box 718 fixed to the outer wall of the greenhouse 1 and a protective cylinder 713 fixed to the bottom surface of the mounting plate 75. The cylinder body of the electric cylinder 76 is located inside the protective cylinder 713, the piston rod of the electric cylinder 76 passes through the bottom surface of the protective cylinder 713, the motor 716 is located inside the protective box 718, and the rotating shaft 717 passes through the outer wall of the protective box 718 on the side away from the screw 72, which can protect the electric cylinder 76 and the motor 716, thereby extending the service life of the electric cylinder 76 and the motor 716.

[0037] It is worth noting that sealing rings are provided at the contact points between the water pipe 6 and the collection box 4 and the inlet pipe 711, and sealing rings are provided at the contact points between the corrugated pipe 712 and the inlet pipe 711 and the outlet pipe 710. Sealing rings are also provided at the contact points between the water box 78 and several drip irrigation heads 79 and the outlet pipe 710. This can improve the sealing of the entire device and prevent water leakage.

[0038] Finally, it should be noted that the components involved in this utility model, such as the shed body 1, electric cylinder 76, and motor 716, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0039] In this embodiment, when drip irrigation is needed for the cut flower plants inside the greenhouse 1, the electric cylinder 76 is first started by the external PLC. The piston rod of the electric cylinder 76 moves, driving the water box 78 fixed to it through the gasket 77. The movement of the water box 78 drives the movement of several drip heads 79 fixed to it. When the several drip heads 79 move to the appropriate height position, the electric cylinder 76 is turned off by the external PLC. Then, an appropriate amount of water is added into the collection box 4. The water in the collection box 4 enters the inlet pipe 711 through the water pipe 6. The water entering the inlet pipe 711 then flows into the corrugated pipe 712 and into the outlet pipe 710. The water entering the outlet pipe 710 then enters the water box 78. The water entering the water box 78 then flows into the several drip heads 79 and drips out from the several drip heads 79.

[0040] Simultaneously, an external PLC starts and controls the output shaft of motor 716 to rotate alternately in both directions. The rotation of the output shaft of motor 716 drives the rotating shaft 717, which is coaxially connected to it, to rotate. The rotating shaft 717 then drives the gear 715, which is coaxially fixed to it on the same side, to rotate. This gear 715 then drives another gear 715 meshing with it, which in turn drives the rotating rod 714, which is coaxially fixed to it, to rotate. The rotating rod 714 then drives the rotating column 71, which is coaxially fixed to it on the same side, to rotate. This rotating column 71 then drives the screw 72, which is coaxially fixed to it, to rotate. The screw 72 then drives the moving block 73, which is threadedly connected to it, to move. The moving block 73 moves under the guidance of the guide block 74 and the guide groove on the top surface of the greenhouse 1. Because the output shaft of the motor 716 rotates alternately in both directions, it indirectly drives the screw 72 to rotate alternately in both directions. The screw 72 rotates alternately in both directions, which drives the moving block 73 to make linear reciprocating motion in the left and right direction inside the greenhouse 1. The movement of the moving block 73 indirectly drives the water box 78 and several drip irrigation heads 79 to make linear reciprocating motion in the left and right direction inside the greenhouse 1. During the process of the several drip irrigation heads 79 making linear reciprocating motion in the left and right direction inside the greenhouse 1, the cut flower plants inside the greenhouse 1 can be drip-irrigated.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
