Description

Technical Field

[0001] This utility model belongs to the field of spray irrigation technology, specifically an automated spray irrigation device. Background Technology

[0002] Polygonatum, also known as chicken-head polygonatum, yellow chicken vegetable, pen-tube vegetable, claw ginseng, tiger ginger, and chicken claw ginseng, is a plant of the Polygonatum genus. Its rhizome is horizontal, cylindrical, with swollen nodes, and its leaves are whorled and sessile. Medicinally, it has the effects of tonifying the spleen, moistening the lungs, and promoting the production of body fluids. Polygonatum can be cultivated outdoors or in greenhouses. Greenhouse-grown Polygonatum requires regular watering. Currently, most greenhouse watering is done manually using hoses. Manual watering is slow, inefficient, and labor-intensive, requiring the movement of hoses. Furthermore, manual watering is uneven, which is detrimental to the growth of Polygonatum. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: an automated spraying and irrigation device, comprising a moving mechanism, a power end, a first steel wire rope, a conveying hose, a moving stabilizing mechanism, and an upper and lower spraying mechanism. The power end is located at one end of the moving mechanism and is connected to the moving mechanism for transmission. The first steel wire rope is located directly below the moving mechanism.

[0006] Preferably, one end of each of the two first rotating shafts is fixedly connected to a worm gear, and the power end includes a reversible motor and an L-shaped connecting strip. The reversible motor and the L-shaped connecting strip are both installed on the top inside the planting greenhouse. A worm is connected between the output end of the reversible motor and the bottom of the inner side of the L-shaped connecting strip. The worm meshes with the two worm gears, thereby enabling effective transmission and adjustment of the moving mechanism.

[0007] Preferably, the moving stabilizing mechanism includes a convex half-strip, with vertical rods fixedly connected at equal intervals to the top of the convex half-strip. The tops of the vertical rods are all fixedly connected to the top of the planting greenhouse. A horizontal plate is provided at the bottom of the convex half-strip, and the horizontal plate is fixedly connected to the top of the fixing block. Two fixing rods are fixedly connected to both ends of the top of the horizontal plate. Rollers are installed on the top of the fixing rods, and the rollers are located on the side of the top of the convex half-strip. This effectively supports the first steel wire rope, the conveying hose, and the upper and lower spraying mechanism, thus facilitating stable movement.

[0008] Preferably, a metal U-shaped rod is fixedly connected to the bottom of the fixing block, the first steel wire rope is located inside the metal U-shaped rod, a metal connecting pipe is fixedly connected to the middle of the bottom of the metal U-shaped rod, and one end of the conveying hose is connected to the metal connecting pipe.

[0009] Preferably, the surface of the first wire rope is movably sleeved with a first collar at equal intervals, and the surface of the first wire rope near the metal U-shaped rod is movably sleeved with a second collar. The conveying hose is fixedly connected to the surfaces of the first collar and the second collar by a fixing buckle. A connecting rod is fixedly connected between the top of the second collar and the bottom of the fixing block, so that the conveying hose can be effectively moved and adjusted.

[0010] Preferably, the upper and lower spraying mechanism includes a horizontal pipe, which is fixedly connected to the bottom of a metal connecting pipe. A first connecting conduit is fixedly connected to the surface of the horizontal pipe. A first horizontal long pipe is fixedly connected to the bottom of the first connecting conduit. Vertical pipes are fixedly connected at equal intervals to the bottom of the first horizontal long pipe. Low-position sprinkler heads are fixedly connected to the bottom of each vertical pipe. A first valve is installed in the middle of the first connecting conduit.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a moving mechanism, a power end, a first steel wire rope, a conveying hose, a moving stabilizing mechanism, and an upper and lower spraying mechanism, this spraying and irrigation device can automatically spray and irrigate the Polygonatum planted in the greenhouse. It can also effectively spray and irrigate according to the size of Polygonatum at different growth stages. At the same time, this spraying and irrigation device can carry out spraying and irrigation operations over a large area, thereby effectively improving the speed and efficiency of watering and irrigation, greatly reducing labor intensity, and enabling uniform spraying and irrigation operations, which is beneficial to the planting and growth of Polygonatum. The spraying and irrigation device has a simple structural design, low manufacturing cost, and is convenient to use and operate. The spraying and irrigation is stable and reliable, and its performance can meet the usage requirements of Polygonatum planting and irrigation.

[0013] By starting the forward and reverse motor, the worm gear rotates, which in turn drives the two worm wheels to rotate. The rotation of the two worm wheels drives the two first rotating shafts to rotate, which in turn drives the two winding wheels on them to rotate. This causes the two winding wheels on one of the first rotating shafts to wind up the two second wire ropes, and the two winding wheels on the other first rotating shaft to unwind the two third wire ropes. The movement of the second and third wire ropes causes the fixed block to move horizontally.

[0014] When the fixed block moves horizontally, it will drive the metal U-shaped rod and the metal connecting pipe to move. At the same time, the movement of the fixed block will drive the second ring to move through the linkage rod, so that the second ring will slide on the surface of the first wire rope. The movement of the second ring will drive the conveying hose to move, and the movement of the conveying hose will drive the first ring to slide on the surface of the first wire rope, so that the conveying hose can be effectively moved and adjusted, and the conveying hose can effectively transport water.

[0015] When the metal connecting pipe moves, it will drive the horizontal pipe, the first connecting conduit, the second connecting conduit, the first horizontal long pipe, the vertical pipe, the low-level sprinkler head, the second connecting conduit, the second horizontal long pipe, and the high-level sprinkler head to move, thereby enabling the low-level sprinkler head and the high-level sprinkler head to move effectively.

[0016] External water is pressurized by an external water pump and delivered through a flexible hose to the interior of the metal connecting pipe. Then, through the first connecting pipe, the second connecting pipe, the first horizontal pipe, and the vertical pipe, low-level sprinkler heads spray water at a low level, while high-level sprinkler heads spray water at a high level through the second connecting pipe and the second horizontal pipe. The vertical pipe allows the low-level sprinkler heads to reach deep into the interior of the Polygonatum plant, effectively spraying water close to the ground, thus ensuring that the tall, lush roots of the Polygonatum are also effectively irrigated. The high-level sprinkler heads effectively spray water onto the tall, lush branches and leaves of the Polygonatum, ensuring even and effective irrigation and promoting its growth.

The power end 2 is located at one end of the moving mechanism 1 and is connected to the moving mechanism 1 for transmission. The first steel wire rope 3 is located directly below the moving mechanism 1. The conveying hose 4 is installed on the surface of the first steel wire rope 3. The moving stabilizing mechanism 5 is located in the middle of the moving mechanism 1, and the lower part of the moving stabilizing mechanism 5 is connected to the moving mechanism 1. The upper and lower spraying mechanism 6 is connected to the bottom of the moving stabilizing mechanism 5, and the upper and lower spraying mechanism 6 is connected to one end of the conveying hose 4. The moving mechanism 1, the power end 2, the first steel wire rope 3, and the moving stabilizing mechanism 5 are all installed inside the planting greenhouse.

The two second steel wire ropes 11 pass through the two second rotating shafts 8 simultaneously. Two pulleys 10 at the end are fixedly connected to one end of two third steel wire ropes 12, and a fixing block 13 is fixedly connected between one end of the two third steel wire ropes 12; one end of each of the two first rotating shafts 7 is fixedly connected to a worm gear 14; the power end 2 includes a forward and reverse motor 15 and an L-shaped connecting strip 16, both of which are installed on the top inside the planting greenhouse; a worm 17 is connected between the output end of the forward and reverse motor 15 and the bottom of the inner side of the L-shaped connecting strip 16; the worm 17 meshes with the two worm gears 14, thereby enabling effective transmission and adjustment of the moving mechanism 1;

[0029] By starting the forward and reverse motor 15, the worm gear 17 rotates. The rotation of the worm gear 17 drives the two worm wheels 14 to rotate. The rotation of the two worm wheels 14 drives the two first rotating shafts 7 to rotate. The rotation of the two first rotating shafts 7 drives the two winding wheels 9 on them to rotate. This causes the two winding wheels 9 on one of the first rotating shafts 7 to wind up the two second wire ropes 11, and causes the two winding wheels 9 on the other first rotating shaft 7 to unwind the two third wire ropes 12. The movement of the second wire ropes 11 and the third wire ropes 12 causes the fixed block 13 to move horizontally.

[0030] In Example 2, based on Example 1, the moving stabilizing mechanism 5 includes a convex half-strip 18. Vertical rods 19 are fixedly connected at equal intervals to the top of the convex half-strip 18, and the tops of the vertical rods 19 are all fixedly connected to the top of the planting greenhouse.

Two fixing rods 21 are fixedly connected to both ends of the top of the horizontal plate 20. Rollers 22 are installed on the top of each fixing rod 21, and the rollers 22 are located on the side of the top of the convex half-strip 18, thus effectively supporting the first wire rope 3, the conveying hose 4, and the upper and lower spraying mechanism 6, which is beneficial for stable movement. The bottom of the fixing block 13 is fixed... A metal U-shaped rod 23 is fixedly connected to the conveying hose 4. A first steel wire rope 3 is located inside the metal U-shaped rod 23. A metal connecting pipe 24 is fixedly connected to the middle of the bottom of the metal U-shaped rod 23. One end of the conveying hose 4 is connected to the metal connecting pipe 24. A first collar 25 is movably sleeved at equal intervals on the surface of the first steel wire rope 3. A second collar 26 is movably sleeved on the side of the first steel wire rope 3 near the metal U-shaped rod 23. The conveying hose 4 is fixedly connected to the surfaces of the first collar 25 and the second collar 26 by a fixing buckle 27. A connecting rod 28 is fixedly connected between the top of the second collar 26 and the bottom of the fixing block 13, so that the conveying hose 4 can be effectively moved and adjusted.

[0031] When the fixed block 13 moves horizontally, it will drive the metal U-shaped rod 23 and the metal connecting pipe 24 to move. At the same time, the movement of the fixed block 13 will drive the second ring 26 to move through the linkage rod 28, so that the second ring 26 slides on the surface of the first wire rope 3. The movement of the second ring 26 will drive the conveying hose 4 to move. The movement of the conveying hose 4 will drive the first ring 25 to slide on the surface of the first wire rope 3, so that the conveying hose 4 can effectively move and adjust its extension and retraction, and can effectively convey water.

[0034] External water, pressurized by an external water pump, is delivered through a flexible hose 4 to the metal connecting pipe 24. Water is then sprayed from the low-level sprinkler head 33 via the first connecting pipe 30, the second connecting pipe 35, the first horizontal pipe 31, and the vertical pipe 32, and from the high-level sprinkler head 39 via the second connecting pipe 35 and the second horizontal pipe 38.
