Description

Technical Field

[0001] This invention relates to the field of water-saving irrigation technology, specifically a water-saving irrigation method. Background Technology

[0002] Irrigation refers to the artificial irrigation activities that utilize water resources in agriculture, landscaping, and plant cultivation. Landscape irrigation refers to a technique for providing water to green landscapes such as gardens, parks, and botanical gardens. Its main purpose is to ensure that plants receive adequate water to maintain their growth and health. Landscape irrigation can be carried out in various ways.

[0003] Application number CN202010768251.X discloses a water-saving irrigation system, which includes a frame. A support is mounted on the side of the frame away from the walking mechanism. A rotating component is rotatably mounted on the support, and the rotating component is connected to a drive mechanism mounted on the support. Two opposing nozzles are rotatably mounted on the rotating component away from the support. The nozzles are connected via a transmission assembly to a fixed shaft that passes through the rotating component and is fixed to the support. The rotating component has a hollow structure, and a buffer cavity is fixed inside it. The buffer cavity is connected to the inside of the nozzles via a connecting pipe. The drive mechanism drives the rotating component to rotate, causing the nozzles to move in a circular motion. When the rotating component rotates, the transmission assembly and the fixed shaft cause the nozzles to reciprocate up and down, thereby increasing the spraying range and effectively avoiding excessive water waste, achieving a water-saving effect.

[0004] For green plants growing in gardens, nutrient solutions need to be added regularly to replenish nutrients. However, the above-mentioned system can only spray water, requiring staff to provide additional nutrients, which increases labor costs. Furthermore, to improve the overall aesthetics of the garden, the green plants are arranged in different shapes and protected by stone steps. The above-mentioned system can only irrigate the green plants in a straight line, and cannot accurately irrigate the edges of the green plants that are arranged in an arc shape, which may result in uneven spraying or the use of more water for irrigation. Therefore, there is a need for a water-saving irrigation method on the market. Summary of the Invention

[0022] This invention further adjusts the irrigation range based on the current edge corner of the green plant. If the edge of the corner is aligned with the direction of the curved plate, the distance between the irrigation device and the edge of the green plant increases when the irrigation system turns. At this time, the rotating plate controls the movable groove to rotate upward through the connecting rod. The movable groove drives the irrigation device to rotate upward, increasing the irrigation range. When the corner direction is opposite to that of the curved plate, the transmission rod rotates in the opposite direction. The drive rod drives the movable groove to rotate downward, causing the irrigation device to move downward and spray precisely onto the roots of the green plant. This avoids problems such as uneven spraying or wasting water resources by using more water to spray the corner. Attached Figure Description

A rubber bottle 6 is provided on the upper side of the mounting bracket 9.

[0042] The mixing mechanism 40 includes a preparation cylinder 43, a magnetic ring 42 slidably connected to the surface of the preparation cylinder 43, and sliding rods 41 fixedly connected to the front and rear sides of the magnetic ring 42. The left side of the sliding rod 41 is movable to the right side of the eccentric wheel 31.

[0044] Limiting blocks 7 are fixedly connected to both the front and rear sides of the housing 1. The sliding rod 41 slides through the inside of the limiting block 7.

A limiting groove 5 is fixedly opened inside the limiting frame 4. The fixed rod 34 moves inside the limiting groove 5.

[0045] When irrigating the green plants in step 3, when the water-saving irrigation system moves to the corner of the stone steps, the arc plate 21 controls the rotating plate 27 to rotate through the connecting rod 22. The rotating plate 27 controls the guide frame 29 to rotate through the connecting frame 25, so that the rotation direction of the right moving wheel 3 corresponds to the edge of the corner, so that the irrigator 206 can always provide nutrient irrigation to the green plants.

[0046] Working principle: such as Figure 9As shown, A represents the system's driving route, B represents the planting area, and C represents the irrigation area before the irrigation system's angle is adjusted. A protective stone step is installed at the edge of B. The curved plate 21 remains in close contact with the stone step at the edge of B, keeping the elastic block 24 in a semi-compressed state, driving the irrigation system to move beside the stone step. The left moving wheel 2 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the eccentric wheel 31 to rotate via the belt 12. The eccentric wheel 31 drives the drive shaft 32, which is fixedly connected to it, to rotate. When the drive shaft 32 rotates, it drives the driven rod 33, which is movably connected to it, to reciprocate up and down. The driven rod 33 drives... The fixed rod 34, which is movably connected to it, moves up and down reciprocally. The fixed rod 34 drives the squeezing block 35 and the active piston rod 36, which are fixedly connected to it, to move up and down reciprocally. The active piston rod 36 draws water out through the reciprocating piston movement in the liquid storage cylinder 10 and enters the preparation cylinder 43 through the hose. When the squeezing block 35 moves downward, it applies pressure to the rubber bottle 6. After the rubber bottle 6 is squeezed, the internal nutrient solution is squeezed out and enters the preparation cylinder 43 through the hose. When the active piston rod 36 moves upward, the rubber bottle 6 resets under its own elasticity, thereby completing the intermittent input of water and nutrient solution by the infusion mechanism 30.

[0047] When the eccentric wheel 31 rotates, it applies a thrust to the sliding rod 41. The sliding rod 41 reciprocates left and right under the cooperation of the eccentric wheel 31 and the spring. The sliding rod 41 drives the magnetic ring 42, which is fixedly connected to it, to reciprocate left and right. The magnetic ring 42 drives the sliding frame 46, which is fixedly connected to it, to reciprocate left and right. At the same time, the magnetic force drives the stirring plate 44 in the preparation cylinder 43 to reciprocate left and right. The stirring plate 44 is threadedly connected to the lead screw 45 while moving left and right. Therefore, the lead screw 45 rotates under the thread drive while moving, thereby stirring the mixed water and nutrient solution. The sliding frame 46 drives the driven piston rod 47, which is fixedly connected to it, to reciprocate left and right. The driven piston rod 47 controls the preparation cylinder 43 to input the stirred mixture into the connecting part 205 through the liquid outlet pipe 48 and spray it out through the irrigation device 206, thereby realizing the irrigation of the green plants.

[0048] like Figure 9As shown, when the irrigation system moves to the corner of B, the arc plate 21 slides backward under the limit of the arc groove 8. The connecting rod 22 drives the hinge plate 23, which is rotatably connected to it, to swing. The hinge plate 23 drives the rotating plate 27, which is rotatably connected to it, to rotate clockwise. The rotating plate 27 drives the driven plate 28, which is rotatably connected to it, to rotate clockwise. The driven plate 28 drives the connecting frame 25, which is rotatably connected to it, to rotate counterclockwise. The connecting frame 25 drives the front and rear guide frames 29 to rotate counterclockwise, so that the rotation direction of the right moving wheel 3 is aligned with the arc shape of B. In a consistent manner, the rotating plate 27 drives the movable frame 26 fixedly connected to it to rotate, the movable frame 26 drives the transmission rod 201 fixedly connected to it to swing in the arc groove 8, the transmission rod 201 drives the drive rod 202 fixedly connected to it to move in the front side inside the movable groove 204, and the rotating frame 203 drives the irrigator 206 to rotate downward and upward under the drive of the drive rod 202. At this time, the irrigation system moves to area C, and the distance between the irrigator 206 and the green plants is the farthest. By controlling the irrigator 206 to rotate upward, the spraying range is increased to achieve the irrigation of the green plants.

[0049] If the irrigation system is irrigating at a corner opposite to the current arc B, the directional mechanism 20 works in the opposite direction to achieve the same direction as the edge of B, while the drive rod 202 controls the irrigator 206 to swing downward, so that the irrigator 206 can accurately irrigate the roots of the green plants.
