Technical Field

The invention relates to the field of gardening and greening, and in particular to a green plant watering system for gardening and greening management and maintenance, and also to a green plant watering method for gardening and greening management and maintenance.

Background technique

In landscaping, green plant seedlings will be cultivated to facilitate their later transplantation to garden landscapes for viewing. However, the maintenance equipment currently used in landscaping mostly adopts a jet structure for watering seedlings with large roots, but when watering delicate seedlings, another maintenance equipment is required for atomizing spraying, which is inconvenient to switch watering methods according to different seedlings. When watering newly planted seedlings, general staff will water them with a large amount of water to ensure that the roots of the seedlings absorb sufficient water, but watering a large amount of water may cause the newly planted seedlings to tilt.

The currently disclosed Chinese patent CN116439099A discloses a garden greening maintenance device, comprising a fixed frame; one end of the fixed frame is connected to a water pipe, and the end of the water pipe away from the fixed frame is connected to a water pump; the fixed frame comprises a long strip of water delivery part and a connecting part located at one end of the water delivery part close to the water pipe; water spraying ports are provided on both sides of the water delivery part of the fixed frame, and there are multiple groups of water spraying ports; the water pipe can be connected to multiple groups of water spraying ports through the inside of the water delivery part; a notch is formed at one corner of the connecting part, and a hose is connected to one side of the notch; one end of the hose away from the connecting part A conversion block is connected; the shape of the conversion block matches the shape of the notch; a conveying frame is fixedly connected to the top of the conversion block; a connecting block is fixedly connected to the outside of the conveying frame, and two groups of connecting blocks are provided; spray heads are fixedly connected to the outside of the two groups of connecting blocks; the conversion block, the conveying frame and the connecting block are all hollow structures to realize water flow; a switching mechanism is provided inside the fixed frame, and the switching mechanism is used to switch the water flow channel; finally, atomization spraying is performed at the spray head on the connecting block, which has the effect of atomization spraying of delicate seedlings, and is convenient for the maintenance and cultivation of different types of seedlings.

According to the above patent, the patent is fixed at the garden seedling cultivation place through the fixed frame, and the water flows to the multiple groups of water spraying ports opened by the fixed frame for spraying, which can spray and irrigate the seedlings with large roots, and the water switches to flow to the spray head for atomization spraying, which can irrigate the delicate seedlings, and play the effect of irrigating different seedlings. However, the patent cannot achieve uniform irrigation effect for each seedling, and the soil around the seedlings is unevenly irrigated, which makes it impossible for the seedling roots to fully absorb the appropriate amount of water. In addition, the direct impact on the seedlings during the irrigation process will also cause the seedlings to be skewed. Therefore, there is a need for an irrigation system that can ensure that the seedlings are protected from damage during the irrigation process and ensure that the seedling roots fully absorb water.

Detailed ways

In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Referring to FIGS. 1 to 7 , a system for watering green plants for landscaping management and maintenance includes a water supply pipeline, a water filter unit and an irrigation unit. The irrigation unit includes a fixed frame 1 and a sprinkler assembly 2. The fixed frame 1 has a matrix-arranged planting port 11. Each planting port 11 is provided with a sprinkler assembly 2. The sprinkler assembly 2 includes a casing 21 in which a seedling can be sleeved. The casing 21 has a water-filled chamber. A separation ring 22 is provided in the water-filled chamber. The water-filled chamber is divided into an upstream space 211 and a downstream space 212 by the separation ring 22. 12, the outer side of the casing 21 is respectively provided with an upper water inlet 2111 and a lower water inlet 2121 which are connected with the upstream space 211 and the downstream space 212, and the inner side of the casing 21 is respectively provided with a water mist spray hole 2112 and a water outlet channel 2122 which are connected with the upstream space 211 and the downstream space 212, the water mist spray hole 2112 and the water outlet channel 2122 are arranged around the casing 21, when the water pressure in the upstream space 211 and the downstream space 212 reaches a specified level, the water flow is in a state of being discharged through the water mist spray hole 2112 and the water outlet channel 2122.

When watering the seedlings of green plants, first, clean water enters the irrigation unit through the water supply pipe, and is purified by the water filtering unit on the way to ensure that the water quality is free of impurities and suitable for plant growth. The purified water is evenly distributed to each sprinkler assembly 2, and the seedlings in the planting port 11 are watered by the sprinkler assembly 2. The housing 21 of each sprinkler assembly 2 fills water into the upstream space 211 and the downstream space 212 through the upper water inlet 2111 and the lower water inlet 2121. When the water pressure in the upstream space 211 reaches the set value, the water passes through the water inside the housing 21. The mist spray hole 2112 sprays out to form a dense water mist, which directly acts on the leaf surface of the seedling and the surrounding air, helping to increase air humidity, reduce leaf surface temperature, promote photosynthesis, and reduce water evaporation loss. When the water pressure in the downstream space 212 reaches the set value, the water in the downstream space 212 is discharged through the water outlet channel 2122 on the inner side of the casing 21, and the water flow slowly and evenly penetrates into the soil around the roots of the seedlings, providing the root system with necessary moisture, promoting the healthy development of the root system, and avoiding soil compaction or root damage caused by direct impact of moisture on the roots of the seedlings.

As shown in Figures 3 to 7, the casing 21 is composed of an inner cover shell 213 and an outer cover shell 214. The gap between the inner cover shell 213 and the outer cover shell 214 is the water-filled chamber. The lower end of the outer cover shell 214 has a ring piece 2141 extending toward the lower end of the inner cover shell 213. The inner cover shell 213 can move relative to the outer cover shell 214 along its axial direction. When the lower end of the inner cover shell 213 does not contact the edge of the ring piece 2141, the water outlet channel 2122 is formed between the lower end of the inner cover shell 213 and the ring piece 2141.

When the inner cover shell 213 moves upward, the distance between the lower end of the inner cover shell 213 and the ring piece 2141 increases, forming an open water outlet channel 2122. The inner cover shell 213 moves downward until the lower end of the inner cover shell 213 contacts the edge of the ring piece 2141, and the water outlet channel 2122 is closed. When irrigation is needed, water is injected into the water filling chamber through the upper water inlet 2111 and the lower water inlet 2121. After the water filling chamber is full, the size of the water outlet channel 2122 is controlled by adjusting the position of the inner cover shell 213. When the lower end of the inner cover shell 213 is away from the ring piece 2141, water flows to the soil through the formed water outlet channel 2122 for root irrigation. At the same time, the water mist spray hole 2112 can also release water mist for leaf spraying.

3, 6 and 7, the upper end of the inner cover shell 213 has a ring sleeve 2131 in contact with the inner wall of the outer cover shell 214, and a compression spring 2132 coaxial with the outer cover shell 214 is fixedly connected between the ring sleeve 2131 and the outer cover shell 214. When the compression spring 2132 is in a state of no external force, the lower end of the inner cover shell 213 contacts the edge of the ring sheet 2141, causing the water outlet channel 2122 to be in a closed state.

When the compression spring 2132 is in a natural state without being acted upon by an external force, the lower end of the inner cover shell 213 is pressed against the edge of the ring piece 2141 at the lower end of the outer cover shell 214 due to the pressure of the compression spring 2132, which completely closes the water outlet channel 2122 formed between the inner cover shell 213 and the ring piece 2141, effectively preventing water from flowing out. At this time, water is filled into the upstream space 211 through the upper water inlet 2111 until it is released from the water mist nozzle 2112 after being pressurized, thereby realizing water mist spraying on the seedlings. When root watering is not needed, closing the water outlet channel 2122 avoids direct contact of water with the root soil, reduces the risk of excessive root moisture, helps prevent the occurrence of root diseases, and protects the healthy development of the seedling root system.

As shown in Figures 7 to 10, the separation ring sleeve 22 is fixedly connected to the inner cover shell 213, and an upper rubber sleeve 221 and a lower rubber sleeve 222 are fixedly connected between the upper and lower ends of the separation ring sleeve 22 and the outer cover shell 214 respectively. When the water outlet channel 2122 is closed, the upstream space 211 and the downstream space 212 are in a closed state.

When it is necessary to open the water outlet channel 2122 to irrigate the roots of the seedlings, water is filled into the downstream space 212 through the lower water inlet 2121 until the separation ring sleeve 22 is pushed up after pressurization, thereby causing the inner cover shell 213 to move upward, and the compression spring 2132 is compressed accordingly. The distance between the inner cover shell 213 and the ring piece 2141 increases, forming an open water outlet channel 2122, maintaining a constant pressurized state, so that water can flow out of the water outlet channel 2122 according to the appropriate opening to perform irrigation operations. Once the pressurized state is stopped, the elastic force of the compression spring 2132 will automatically push the inner cover shell 213 downward back to its original position, and the water outlet channel 2122 will be closed again, thereby automatically stopping watering the roots of the seedlings. The upper rubber sleeve 221 and the lower rubber sleeve 222 are respectively located at The upper and lower ends of the separation ring sleeve 22 are fixedly connected to the outer cover shell 214 to form a sealing structure. When the water outlet channel 2122 is closed, the upper rubber sleeve 221 and the lower rubber sleeve 222 ensure that the upstream space 211 and the downstream space 212 are independently in a closed state, effectively controlling the pressurization of the water flow, ensuring that the water flow can flow out from the water mist spray hole 2112 and the water outlet channel 2122 respectively. When foliar spraying is not required, the water outlet channel 2122 is opened to ensure the precise supply of water. Due to the way of opening the water outlet channel 2122 after pressurization, the water flow can circle around and irrigate the soil around the seedlings, achieving a uniform watering effect, which is beneficial to the full absorption of the roots of the seedlings, improves the spraying efficiency, and at the same time saves water resources and promotes the healthy growth of plants.

As shown in FIG. 6 , the inner side of the outer cover shell 214 has a step 2142 that can contact the ring sleeve 2131 . When the ring sleeve 2131 contacts the step 2142 , the water outlet channel 2122 is in a closed state.

When the compression spring 2132 between the inner housing shell 213 and the outer housing shell 214 is in a state of being free from external force, the ring sleeve 2131 on the inner housing shell 213 is in contact with the step 2142 on the outer housing shell 214, and the gap between the inner housing shell 213 and the ring sheet 2141 is closed, ensuring the tight closure of the water outlet channel 2122, effectively preventing water leakage when there is no need for irrigation. When irrigation is required, pressurization is applied through the upper water inlet 2111 or the lower water inlet 2121, water is filled and sufficient pressure is applied. As the pressure increases, the water pressure acts on the ring sleeve 21 31, it overcomes the constraint of the compression spring 2132 or its own gravity, moves upward and separates from the step 2142 of the outer cover shell 214, and the inner cover shell 213 moves upward accordingly, and the distance between it and the ring piece 2141 increases, and the water outlet channel 2122 is immediately opened to allow water to flow through, and the root irrigation process begins. When the root irrigation is completed, the external pressurization is cancelled, the water pressure naturally decreases, and the ring sleeve 2131 is reset under the action of elastic force and contacts with the step 2142 of the outer cover shell 214 again, and the water outlet channel 2122 is closed again, returning to the initial closed state, waiting for the next root irrigation instruction.

1 to 7 , each implantation opening 11 on the fixing frame 1 is provided with a base 12 for supporting the casing 21 , and the base 12 has a groove capable of contacting and fitting with the ring piece 2141 .

When the sleeve 21 is placed into the planting opening 11, the ring piece 2141 is just embedded in the groove of the base 12, thereby achieving stable support and positioning of the sleeve 21. The close fit between the groove and the ring piece 2141 not only ensures the stability of the sleeve 21 during irrigation and prevents displacement or falling off due to water flow impact or external force, but also enables the sleeve 21 to withstand a certain soil pressure and the thrust generated by plant growth to maintain stable irrigation operation. When the inner cover shell 213 moves upward under pressure, the water outlet channel 2122 is immediately opened, and the water flows smoothly through the gap between the ring piece 2141 and the inner cover shell 213 and is evenly distributed to the soil at the roots of the seedlings, thereby ensuring the precise guidance of the water flow, avoiding random splashing or concentrated discharge of water, and further improving the uniformity and efficiency of irrigation.

1 to 7 , a movable frame 3 capable of controlling the movement of all inner cover shells 213 is provided on the fixed frame 1 and is movable relative to the fixed frame 1 .

Through the driving device, which is not shown in the figure, the operator can control the up and down movement of the movable frame 3, thereby driving all the inner cover shells 213 to move up or down synchronously. When the movable frame 3 drives the inner cover shells 213 to move up collectively, the water outlet channels 2122 of all the shells 21 are opened at the same time, and the root irrigation mode can be quickly switched. On the contrary, when the movable frame 3 moves down, the inner cover shells 213 contact the annular piece 2141, all the water outlet channels 2122 are closed, and the irrigation is stopped or switched to the foliar spraying mode, thereby realizing a rapid and unified conversion of the irrigation mode. It is also possible to simultaneously perform the root irrigation and liquid surface spraying modes when the water outlet channels 2122 are opened, thereby ensuring the synchronous processing of all seedlings during the irrigation process, avoiding the tediousness and time delay of individual operations, and greatly improving the efficiency of irrigation operations.

1 to 7 , a rod 31 fixedly connected to the inner cover shell 213 is provided at each planting opening 11 on the movable frame 3 .

When the height of the green plants grows to the point where the irrigation position needs to be adjusted, the drive device is activated to move the fixed frame 1 together with the movable frame 3 and all the rods 31 and the inner cover shell 213 connected thereto upward as a whole to adapt to the new height of the green plants. During the upward movement, ensure that each inner cover shell 213 maintains an appropriate distance from the roots of the green plants. Without affecting the green plants, effectively ensure that the water flowing out of the water outlet channel 2122 drips onto the soil around the green plants, ensuring that the irrigation water can accurately reach the root area. After adjusting to the appropriate position, lock the movable frame 3 and the fixed frame 1 to ensure stable irrigation.

1 , 2 and 5 , a guide rail 4 is provided around the fixed frame 1 to guide the movable frame 3 to move, so that each housing 21 can be aligned with a corresponding planting opening 11 .

Through the precise guidance of the guide rail 4, it is ensured that each plant can get accurate and uniform water supply during the irrigation process. Even after multiple height adjustments, the high efficiency and precision of irrigation can be maintained. Compared with the traditional method of extensive watering, precise positioning of irrigation for each plant is achieved, ensuring that water directly and fully acts on the leaves and roots of green plants, reducing water waste and improving irrigation efficiency.

A method for watering green plants in a garden greening management and maintenance is applied to a green plant watering system in a garden greening management and maintenance, comprising the following steps:

S1. According to the layout of the garden and the distribution of plant planting, rationally plan and install water supply pipelines, water filtration units and irrigation units;

S2, start the water supply of the upstream space 211, and after the water pressure reaches the set value, spray fine water mist through the water mist spray hole 2112 to provide moisture and a moderate humidity environment for the leaf surface;

S3, start the water supply of the downstream space 212, and the water slowly penetrates into the soil at the roots of the seedlings through the water outlet channel 2122, ensuring that the roots are adequately hydrated and promoting healthy growth of the roots;

S4. Check the growth of plants regularly and adjust the irrigation amount according to the actual needs of the plants.

The present invention divides the water-filled chamber in the casing 21 into an upstream space 211 and a downstream space 212 by means of a separation ring 22, so that water can be sprayed with water mist and watered at the roots through the casing 21. By independently controlling the water volume and water pressure of the upstream space 211 and the downstream space 212, the watering of the seedlings by direct impact of water flow is avoided according to the different growth stages and actual needs of the seedlings, and the amount of foliar spraying and root watering is adjusted respectively. Compared with traditional irrigation methods, the ineffective loss of water is reduced, and the utilization efficiency of water resources is significantly improved.
