Description

Technical Field

[0001] This invention belongs to the field of landscape structure technology, specifically a sponge city landscape structure. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept, referring to cities that can function like a sponge, exhibiting good resilience in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called a "water-resilient city." The internationally accepted term is "low-impact development stormwater system construction," which involves absorbing, storing, infiltrating, and purifying rainwater when it falls, and releasing and utilizing the stored water when needed.

[0003] In order to provide the trees with the planned growth environment during the growth process, it is necessary to artificially regulate the trees. The water stored in the sponge city needs to be used to irrigate the vegetation and trees in the garden so that the trees can get enough water and avoid dying.

[0004] Currently, when irrigating vegetation, sprayers are generally used to spray the vegetation surface directly, and the same applies when irrigating trees. However, some of this water only dissolves in the soil surface, and only a small amount of water penetrates the tree roots. This can lead to a waste of a lot of water during a single watering, as it cannot directly irrigate the tree roots and thus affects the tree's growth.

[0005] Therefore, the present invention provides a sponge city garden structure. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is: a sponge city garden structure as described in this invention; comprising...

[0008] The garden area on the ground contains several conveyor belts that run along guide rails.

[0009] It also includes at least one set of movable wheels, which are rotatably connected around the lower end face of the conveyor seat, and one of the movable wheels is connected to an external drive motor;

[0010] A water storage tank is fixedly attached to the upper end face of the conveyor seat;

[0011] The spray pipe is fixed to the side wall of the water storage tank and extends into the water storage tank. The spray pipe is controlled by an external water pump, which is installed in the delivery seat.

[0012] The mounting bracket is installed on the upper surface of the conveyor seat near the water storage tank.

[0013] The dredging mechanism is installed inside the mounting frame and is used to dredge the soil in the garden downwards.

[0014] During operation, when watering vegetation in the garden, the moving wheels under the conveyor seat are controlled to move the conveyor seat along a preset guide rail towards the vegetation. Then, the water pump is controlled to spray water from the water tank through the spray pipe to spray the vegetation. When watering some trees, the moving wheels are controlled to move the conveyor seat to the side of the tree. Then, the unblocking mechanism in the mounting frame is controlled to drill down the soil of the tree. After that, water can be directly sprayed onto the tree roots through the spray pipe. This solves the problem in the existing technology where watering trees in the garden is usually done by directly pouring water onto the soil surface. Some water only dissolves in the soil surface layer, and only a small amount of water penetrates into the tree roots, which may waste a lot of water in one watering. This technology not only waters the tree roots directly but also saves a lot of water.

[0015] Preferably, the dredging mechanism includes a fixed seat fixed to the end face of the mounting frame; a circular groove is opened in the fixed seat, and a drill rod is rotatably connected in the circular groove; the upper end of the drill rod is connected to an external motor through a gear set; during operation, when the conveyor seat moves the tree to a suitable watering position, the external motor is controlled to drive the drill rod to drill into the soil, which loosens the soil on the one hand and opens the soil on the other hand, so that water can be directly poured into the tree roots through the opened hole.

[0016] Preferably, the drill rod has a through groove inside; the shape of the through groove is adapted to the shape of the spray pipe; multiple rectangular grooves are formed on the outer circumference of the through groove; the rectangular grooves extend through the drill rod; the rectangular grooves are arranged sequentially from top to bottom; during operation, when the drill rod drills into the soil, the operator places the spray pipe in the through groove, and then water is delivered from the spray pipe into the through groove. Because rectangular grooves are set in the through groove, water will flow into the soil from the rectangular grooves at different positions. By designing multiple rectangular grooves, not only is the irrigation range of water to the soil increased, but water can also be directly poured into the soil, making it easier for water to come into contact with the tree roots.

[0017] Preferably, an installation groove is formed on the outer circumferential surface of the drill rod at a position corresponding to the rectangular groove; a crossbar is fixedly connected in each installation groove; a baffle plate is rotatably connected to the outer circumferential surface of the crossbar; the shape of the baffle plate matches the shape of the rectangular groove; the baffle plate has a downward opening design; an adjustment mechanism is provided in the through groove, which is used to open the baffle plate; in the initial state, the baffle plate blocks the installation groove, so that the installation groove and the rectangular groove are in a closed state, which can reduce the problem that some soil enters the through groove from the rectangular groove during the drilling process, making it difficult for the subsequent spray pipe to extend into the through groove; when the drill rod drills to a certain depth, the baffle plate is opened by adjusting the mechanism, which opens by rotating upward, so that it no longer blocks the installation groove and the rectangular groove, and then facilitates the water in the spray pipe to flow out from the rectangular groove.

[0018] Preferably, each of the shielding plates has a breaking rod fixed to its outer surface, and there are two breaking rods on the surface of each shielding plate. Each breaking rod is conical in shape. The breaking rods are arranged linearly on the end face of the shielding plate. The conical end of the breaking rod is facing downward. During operation, when the drilling rod drills into the soil, the breaking rods on the outer surface of the shielding plate can loosen the soil to a certain extent, which is conducive to the growth of trees.

[0019] Preferably, the adjusting mechanism includes a through rod slidably disposed inside the through groove; a vertical groove is formed inside the through rod; multiple flow grooves are formed on the outer circumferential surface of the through rod; a fixed rod is fixedly connected to each flow groove; a deflection pressure rod is rotatably connected to the outer circumferential surface of the fixed rod; a limit spring is fixedly connected to the side wall of the deflection pressure rod; the side of the limit spring away from the deflection pressure rod is fixedly connected to the side wall of the through rod; during operation, in the initial state, the through rod is not in the through groove. When the drill rod drills to a certain depth in the soil, the operator moves the through rod downward from above the through groove. Due to the deflection of the deflection pressure rod... As the deflector moves downwards along the inner wall of the through-groove, it approaches the side closer to the through-bar. The deflector then contacts the inner wall of the through-groove and is compressed, thus compressing the limiting spring. When the deflector aligns with the baffle at different positions, a gap exists between them, and the compressive force on the limiting spring decreases. Consequently, the deflector rotates towards the baffle, applying pressure to it and causing it to rotate towards the soil. This prevents the baffle from blocking the rectangular groove, allowing water to flow freely and directly irrigate the tree roots.

[0020] Preferably, the diameter of the through rod is smaller than the diameter of the through groove; the shape of the flow groove is adapted to the shape of the rectangular groove; the deflecting pressure rod and the baffle are arranged in a one-to-one correspondence; during operation, when the deflecting pressure rod pushes out the baffle, the spray pipe is placed in the vertical groove, and then water can be poured onto the roots of the tree through the flow groove and the rectangular groove in the vertical groove.

[0021] Preferably, there is a gap between the deflecting rod and the shielding plate; during the downward movement of the deflecting rod, its end will press against the side wall of the shielding plate; since there is a gap between the deflecting rod and the shielding plate, the deflecting rod can easily press against the shielding plate, causing the shielding plate to rotate towards the side closer to the soil.

[0022] Preferably, an electric push rod is fixedly connected to the side of the deflecting rod near the shield; a push plate is fixedly connected to the telescopic end of the electric push rod; when it is necessary to increase the distance between the soil on one side of the deflecting rod and the drill rod, the operator controls the electric push rod on one side of the deflecting rod to move the push plate towards the soil side, compressing the loose soil and increasing the distance between the soil and the drill rod. This allows more water to be delivered to the gap between the soil and the drill rod, regulating the amount of water used for irrigation, which is beneficial to the growth of tree roots. This solves the problem in the prior art where watering trees in gardens is generally done directly on the soil surface, with some water only dissolving in the soil surface and only a small amount of water reaching the tree roots, potentially wasting a lot of water in one watering session. This method not only allows direct irrigation of the tree roots but also saves a significant amount of water.

[0023] Preferably, the outer circumferential surface of the through rod is fixed with multiple hinge frames; the fixed rod is disposed inside the hinge frames; the width of the deflecting pressure rod is smaller than the width of the hinge frames; during operation, the hinge frames facilitate the movement of the deflecting pressure rod within the inner wall of the through groove, thereby facilitating the pushing out and rotating of the baffle plate.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The sponge city garden structure described in this invention directly waters the roots of trees through spray pipes, solving the problem in the prior art where watering trees in gardens is generally done by directly watering the soil surface, with some water only dissolving in the soil surface layer and only a small amount of water reaching the tree roots, resulting in a large waste of water in a single watering. This invention not only waters the tree roots directly but also saves a significant amount of water.

[0026] 2. The sponge city garden structure described in this invention uses an external motor to drive a drilling rod to drill into the soil, which loosens the soil and opens up the soil, making it easier to directly irrigate the tree roots through the drilled holes.

[0027] 3. The sponge city garden structure described in this invention uses a deflecting pressure bar to rotate towards the side closer to the shielding plate, applying a certain pressure to the shielding plate, causing it to rotate towards the side closer to the soil. This prevents the shielding plate from blocking the rectangular groove, allowing water to flow out of the rectangular groove and enabling direct irrigation of the tree roots.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Example

[0039] like Figures 1 to 3 As shown in the figure, a sponge city garden structure according to an embodiment of the present invention includes a garden area on the ground, and several conveyor seats 1 running along guide rails are arranged inside the garden area;

[0040] It also includes at least one set of movable wheels 2, which are rotatably connected around the lower end face of the conveyor seat 1, and one of the movable wheels 2 is connected to an external drive motor;

[0041] Water storage tank 3 is fixedly connected to the upper end face of the conveyor seat 1;

[0042] Spray pipe 4 is fixed to the side wall of the water storage tank 3 and extends into the water storage tank 3. The spray pipe 4 is controlled by an external water pump, which is installed in the delivery seat 1.

[0043] Mounting bracket 5 is installed on the upper end face of the conveying seat 1 near the water storage tank 3;

[0044] The dredging mechanism is installed inside the mounting frame 5 and is used to dredge the soil in the garden downwards.

[0045] During operation, when watering vegetation in the garden, the moving wheels 2 under the conveyor seat 1 are controlled to move the conveyor seat 1 closer to the vegetation via a preset guide rail. Then, the water pump is controlled to spray water from the water tank 3 through the spray pipe 4 to spray the vegetation. When watering some trees, the moving wheels 2 are controlled to move the conveyor seat 1 to the side of the tree. Then, the dredging mechanism in the mounting frame 5 is controlled to drill the soil of the tree downwards. After that, water can be directly applied to the roots of the tree through the spray pipe 4. This solves the problem in the existing technology where watering trees in the garden is usually done by directly watering the soil surface. Some water will only dissolve in the soil surface layer, and only a small amount of water will penetrate into the roots of the tree, which may waste a lot of water in one watering. This technology can not only directly water the roots of the tree, but also save a lot of water.

[0046] like Figures 2 to 6 As shown, the dredging mechanism includes a fixed base 501 fixed to the end face of the mounting frame 5; a circular groove is opened in the fixed base 501, and a drill rod 6 is rotatably connected in the circular groove; the upper end of the drill rod 6 is connected to an external motor through a gear set, which is not shown in the figure; during operation, when the conveyor seat 1 moves the tree to a suitable watering position, the external motor is controlled to drive the drill rod 6 to drill into the soil, which loosens the soil on the one hand and opens the soil on the other hand, so that water can be directly poured into the tree roots through the opened hole.

[0047] like Figures 2 to 6As shown, the drill rod 6 has a through groove 601 inside; the shape of the through groove 601 is adapted to the shape of the spray pipe 4; multiple rectangular grooves 7 are formed on the outer circumference of the through groove 601; the rectangular grooves 7 extend through the drill rod 6; the rectangular grooves 7 are arranged sequentially from top to bottom; during operation, when the drill rod 6 drills into the soil, the operator places the spray pipe 4 into the through groove 601, and then water is delivered from the spray pipe 4 into the through groove 601. Because rectangular grooves 7 are set in the through groove 601, water will flow into the soil from the rectangular grooves 7 at different positions. By designing multiple rectangular grooves 7, not only is the irrigation range of water to the soil increased, but water can also be directly poured into the soil, making it easier for water to come into contact with the tree roots.

[0048] like Figures 3 to 7 As shown, an installation groove 8 is provided on the outer circumferential surface of the drill rod 6 at a position corresponding to the rectangular groove 7; a crossbar 9 is fixedly connected in each installation groove 8; a baffle plate 10 is rotatably connected to the outer circumferential surface of the crossbar 9; the shape of the baffle plate 10 is adapted to the shape of the rectangular groove 7; the baffle plate 10 is designed to open downwards; an adjustment mechanism is provided in the through groove 601, which is used to open the baffle plate 10; in the initial state, the baffle plate 10 blocks the installation groove 8, so that the installation groove 8 and the rectangular groove 7 are in a closed state, which can reduce the problem that some soil enters the through groove 601 from the rectangular groove 7 during the drilling process of the drill rod 6, making it difficult for the subsequent spray pipe 4 to extend into the through groove 601; when the drill rod 6 drills to a certain depth, the baffle plate 10 is opened by adjusting the mechanism, which opens by rotating upwards, so that it no longer blocks the installation groove 8 and the rectangular groove 7, and then facilitates the water in the spray pipe 4 to flow out from the rectangular groove 7.

[0049] Furthermore, the design of the shield 10, which opens by rotating upwards from the bottom, can further reduce the amount of soil entering the through groove 601 from the installation groove 8.

[0050] like Figures 3 to 7 As shown, each of the shielding plates 10 has a breaking rod 11 fixed to its outer surface. There are two breaking rods 11 on the surface of a single shielding plate 10, and each breaking rod 11 is conical in shape. The breaking rods 11 are arranged linearly on the end face of the shielding plate 10. The conical end of the breaking rod 11 is facing downward. During operation, when the drilling rod 6 drills into the soil, the breaking rods 11 are set on the outer surface of the shielding plate 10. Under the action of the breaking rods 11, the soil can be loosened to a certain extent, so that the loosened soil is conducive to the growth of trees.

[0051] like Figures 3 to 7As shown, the adjusting mechanism includes a through rod 12 slidably disposed inside the through groove 601; a vertical groove 13 is formed inside the through rod 12; multiple flow grooves 14 are formed on the outer circumferential surface of the through rod 12; a fixed rod 15 is fixedly connected to each flow groove 14; a deflection pressure rod 16 is rotatably connected to the outer circumferential surface of the fixed rod 15; a limit spring 17 is fixedly connected to the side wall of the deflection pressure rod 16; the side of the limit spring 17 away from the deflection pressure rod 16 is fixedly connected to the side wall of the through rod 12; during operation, in the initial state, the through rod 12 is not in the through groove 601. When the drill rod 6 drills to a certain depth in the soil, the operator moves the through rod 12 downward from above the through groove 601, as... Figure 5 As shown, since the deflection direction of the deflection rod 16 is towards the side closer to the through rod 12, when the through rod 12 moves downward along the inner wall of the through groove 601, the deflection rod 16 will contact the inner wall of the through groove 601, and the deflection rod 16 will be in a compressed state, compressing the limiting spring 17. When the deflection rod 16 at different positions corresponds to the baffle plate 10, there is a gap between the deflection rod 16 and the baffle plate 10, and the squeezing force on the limiting spring 17 becomes smaller. Therefore, the deflection rod 16 will rotate towards the side closer to the baffle plate 10 and give the baffle plate 10 a certain pressure, causing the baffle plate 10 to rotate towards the side closer to the soil, thereby preventing the baffle plate 10 from blocking the rectangular groove 7. This allows water to flow out of the rectangular groove 7, realizing the function of directly irrigating the tree roots.

[0052] The diameter of the through rod 12 is smaller than the diameter of the through groove 601; the shape of the flow groove 14 is adapted to the shape of the rectangular groove 7; the deflecting pressure rod 16 and the baffle plate 10 are arranged in a one-to-one correspondence; during operation, when the deflecting pressure rod 16 pushes out the baffle plate 10, the spray pipe 4 is placed in the vertical groove 13, and then water can be poured onto the roots of the tree through the flow groove 14 and the rectangular groove 7 in the vertical groove 13.

[0053] There is a gap between the deflecting rod 16 and the shielding plate 10; during the downward movement of the deflecting rod 16, its end will press against the side wall of the shielding plate 10; since there is a gap between the deflecting rod 16 and the shielding plate 10, the deflecting rod 16 can easily press against the shielding plate 10, causing the shielding plate 10 to rotate towards the side closer to the soil.

[0054] like Figures 4 to 7As shown, an electric push rod 18 is fixedly connected to the side of the deflecting rod 16 near the shielding plate 10; a push plate 19 is fixedly connected to the telescopic end of the electric push rod 18; when it is necessary to increase the distance between the soil on one side of the deflecting rod 16 and the drill rod 6, the operator controls the electric push rod 18 on one side of the deflecting rod 16, so that the electric push rod 18 drives the push plate 19 to move towards the soil side, so that the loose soil is squeezed, thereby increasing the distance between the soil and the drill rod 6. In this way, more water can be delivered to the gap between the soil and the drill rod 6, and the amount of water for irrigation can be adjusted, which is beneficial to the growth of tree roots. This solves the problem in the prior art that when watering trees in gardens, water is generally poured directly onto the soil surface, and some water will only dissolve in the soil surface layer, and only a small amount of water will be absorbed into the tree roots, which may waste a lot of water in one watering. This method can not only directly irrigate the roots of trees, but also save a lot of water.

[0055] Multiple hinge frames 20 are fixed to the outer circumferential surface of the through rod 12; the fixed rod 15 is disposed inside the hinge frame 20; the width of the deflection pressure rod 16 is smaller than the width of the hinge frame 20; during operation, the hinge frame 20 is provided to facilitate the movement of the deflection pressure rod 16 on the inner wall of the through groove 601, thereby facilitating the push-out rotation of the baffle plate 10.

[0056] During operation, when watering the vegetation in the garden, the moving wheels 2 under the conveyor seat 1 are controlled to move the conveyor seat 1 closer to the vegetation via the preset guide rail. Then, the water pump is controlled to spray the water in the water tank 3 from the spray pipe 4 to spray the vegetation. When watering some trees is needed, the moving wheels 2 are controlled to move the conveyor seat 1 to the side of the tree. The external motor is controlled to drive the drilling rod 6 to drill into the soil, which loosens the soil and opens it up, making it easier to water the tree roots directly through the drilled holes.

[0057] In the initial state, the baffle plate 10 seals the mounting groove 8, keeping the mounting groove 8 and the rectangular groove 7 closed. This reduces the problem that some soil may enter the penetration groove 601 from the rectangular groove 7 during the drilling process, making it difficult for the subsequent spray pipe 4 to extend into the penetration groove 601. When the drilling rod 6 drills to a certain depth, the baffle plate 10 is opened by adjusting the mechanism by rotating upwards, so that it no longer blocks the mounting groove 8 and the rectangular groove 7, allowing water in the spray pipe 4 to flow out from the rectangular groove 7.

[0058] Furthermore, the design of the shield 10, which opens by rotating upwards from the bottom, can further reduce the amount of soil entering the through groove 601 from the installation groove 8.

[0059] Initially, the penetrating rod 12 is not inside the penetrating groove 601. When the drill rod 6 drills to a certain depth in the soil, the worker moves the penetrating rod 12 downward from above the penetrating groove 601, as shown in the figure. Since the deflection direction of the deflection pressure rod 16 is towards the side closer to the penetrating rod 12, the deflection pressure rod 16 will contact the inner wall of the penetrating groove 601 when the penetrating rod 12 moves downward along the inner wall of the penetrating groove 601, and the deflection pressure rod 16 is in a compressed state, compressing the limiting spring 17. When the deflection pressure rod 16 at different positions corresponds to the baffle plate 10, the deflection pressure rod 16... There is a gap between the shielding plate 10 and the limiting spring 17, and the squeezing force is reduced. Therefore, the deflecting rod 16 will rotate towards the side closer to the shielding plate 10 and apply a certain pressure to the shielding plate 10, causing the shielding plate 10 to rotate towards the side closer to the soil. This prevents the shielding plate 10 from blocking the rectangular groove 7, allowing water to flow out of the rectangular groove 7 and enabling direct irrigation of the tree roots. When the deflecting rod 16 pushes the shielding plate 10 out, the spray pipe 4 is placed in the vertical groove 13. Water can then be irrigated to the tree roots through the flow channel 14 in the vertical groove 13 and the rectangular groove 7.

[0060] When it is necessary to increase the distance between the soil on one side of the deflection rod 16 and the drill rod 6, the operator controls the electric push rod 18 on one side of the deflection rod 16. The electric push rod 18 drives the push plate 19 to move towards the soil, compressing the loose soil and increasing the distance between the soil and the drill rod 6. This allows more water to be delivered to the gap between the soil and the drill rod 6, regulating the amount of water used for irrigation. This is beneficial for the growth of tree roots and solves the problem in existing technologies where watering trees in gardens is usually done directly on the soil surface. Some water only dissolves in the soil surface, and only a small amount of water penetrates the tree roots, which may result in a large amount of water being wasted during a single watering. This method not only allows for direct irrigation of the tree roots but also saves a significant amount of water.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
