Description

Technical Field

[0001] The invention relates to the technical field of root waterers, in particular to a root waterer for seedlings in a central dividing strip of an expressway. Background Art

[0002] In order to soundproof and reduce noise and beautify the environment, green trees are usually planted in the central median of the highway. Trees can act as physical barriers, absorb and disperse some traffic noise, reduce visual interference between oncoming traffic, and reduce the risk of accidents caused by distracted drivers; secondly, trees can also beautify the environment of the highway, improve the road landscape, and make drivers and passengers feel more comfortable and pleasant during long-distance travel. Since the seedlings in the central median are not easy to be irrigated by sprinkler trucks, they are usually watered with the help of root waterers.

[0003] In the existing patent literature, there is a patent with publication number CN118318718B, entitled "A submerged potted seedling root waterer and watering method thereof". This patent and many existing waterers do not provide air or oxygen around the underground roots when supplying water to the roots. The roots will breathe when absorbing water. If the roots are in a humid and oxygen-deficient condition for a long time, it is easy to cause root rot, which is not conducive to the healthy growth of the seedlings. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a root waterer for seedlings in the central dividing strip of a highway. The root waterer is equipped with a semi-circular root air supply assembly. The outside air can directly pass through the semi-circular root air supply assembly to the root system of the seedlings, thereby increasing the oxygen content around the root system and facilitating the respiration of the root system. Therefore, when water is supplied to the root system for a long time, the root system will not easily rot, which is more conducive to the healthy growth of the seedlings.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0006] A root water supply device for seedlings in the central dividing strip of a highway comprises two semi-encircling root water supply components installed opposite to each other, wherein the two semi-encircling root water supply components can form a complete encircling root water supply component;

[0007] A semi-encircled root air supply assembly is also plugged and installed in each semi-encircled root water supply assembly, and both the semi-encircled root water supply assembly and the semi-encircled root air supply assembly are buried underground;

[0008] Each semi-encircled root water supply assembly is connected to a main water supply pipeline above, and the main water supply pipeline is installed on the ground;

[0009] A water-flushing transmission mechanism is installed between each main water supply pipeline and the semi-encircled root water supply assembly, and an intermittent air acceleration flow mechanism is installed above each semi-encircled root air supply assembly; the water-flushing transmission mechanism and the intermittent air acceleration flow mechanism are located at the same height and transmit the action to the intermittent air acceleration flow mechanism, and when there is water flow impact in the water-flushing transmission mechanism, the water-flushing transmission mechanism can act on the intermittent air acceleration flow mechanism to speed up the flow of air in the semi-encircled root air supply assembly.

[0010] By adopting the above scheme, firstly, the root waterer is provided with a semi-encircling root air supply assembly, and the outside air can directly pass through the root system of the seedlings through the semi-encircling root air supply assembly, so that the oxygen content around the root system is increased, which is conducive to the respiration of the root system. Therefore, when water is supplied to the root system for a long time, the root system is not easy to rot, which is more conducive to the healthy growth of the seedlings; secondly, after the semi-encircling root water supply assembly of the root waterer is plugged into the semi-encircling root water supply assembly, the entire encircling root water supply assembly will be more stable, which can restrain the roots of the seedlings, thereby preventing them from extending outward and damaging the foundation of the highway; finally, when the root waterer is supplying water, there will be water flow impact in the water-flushing transmission mechanism, and the intermittent air acceleration flow mechanism can act through the water-flushing transmission mechanism to accelerate the fluidity of the air in the semi-encircling root air supply assembly, provide air with faster fluidity when supplying water, further increase the oxygen content around the root system, and help the root system to breathe when absorbing water.

[0011] As a preferred embodiment of a root waterer for seedlings in the central dividing strip of a highway, the semi-circular root air supply assembly includes a linear air pipe, to which is connected a plurality of semi-circular air pipes that are horizontally arranged and distributed side by side up and down; all the semi-circular air pipes are commonly connected to a plurality of air supply pipes distributed in a circular array, and the air supply pipes are provided with a plurality of air supply holes distributed in a linear array along their length.

[0012] By adopting the above scheme, in order to achieve uniform air supply, air is supplied from the linear air supply pipe to each semi-circular air supply pipe, and then enters the air supply pipe, and finally the air is discharged from the air supply hole, so as to evenly supply air around the root system.

[0013] As a preferred embodiment of a root waterer for seedlings in the central dividing strip of a highway, a semi-encircling air pipe has a wall thereof provided with a plurality of grooves distributed in a circumferential array, each groove being filled with a water storage sponge segment; wherein the water storage sponge segment is cut off one third of its diameter in a radial direction, and an air vent is provided in the radial direction through the center of the water storage sponge segment.

[0014] By adopting the above scheme, in order to store water around the root system, a water storage sponge segment is set up, and the excess water in the soil will be absorbed and stored by the water storage sponge segment, so as to facilitate the subsequent supply to the root system; and the water storage sponge segment is cut off one third of its diameter along its radial direction, so as to avoid the water storage sponge segment affecting the normal air transportation.

[0015] As a preferred embodiment of a seedling root watering device in the central dividing strip of a highway, the water-jet transmission mechanism includes a water flow box, the interior of which is rotatably connected to an impeller; a guide seat located above the impeller is fixed inside the water flow box; a transmission swing arm that can rotate with the impeller is fixed outside the water flow box, and the length of the transmission swing arm is greater than the length of the fan blade;

[0016] The guide seat is tilted in a "slide-like" manner, and an opening eccentric to one side of the impeller shaft is provided at the bottom of the guide seat, and the lower part of the opening corresponds to the blades of the impeller.

[0017] By adopting the above scheme, in order to realize the operation of the intermittent air acceleration flow mechanism, a water-jet transmission mechanism is set up. When there is water flow impact in the water-jet transmission mechanism, the transmission swing arm rotates with the impeller, and the transmission swing arm will act on the intermittent air acceleration flow mechanism, thereby realizing the operation of the intermittent air acceleration flow mechanism.

[0018] As a preferred embodiment of a seedling root watering device in the central dividing strip of a highway, the intermittent air acceleration flow mechanism includes an air box, a push block that can move up and down is installed inside the air box, and a corrugated air plug that is interference-fitted with the inner wall of the air box is installed on the outer limit of the push block; a vertically arranged main push rod is fixed above the push block; a guide seat is fixed on the top of the main push rod, and the guide seat is slidably installed on a guide shaft 1 fixed inside the air box, and a spring 1 is sleeved on the guide shaft 1 for pushing the guide seat to move upward; an auxiliary push rod that is horizontally arranged and penetrates the outside of the air box is fixed on the side wall of the main push rod, and the auxiliary push rod is located in an avoidance groove vertically opened on the side wall of the air box; the auxiliary push rod can conflict with the transmission swing arm when rotating, and the auxiliary push rod can press down when it conflicts with the transmission swing arm;

[0019] Among them, two mutually symmetrical one-way air intake valve assemblies are also installed at the lower end of the air box body. The bottom of the push block is connected to the one-way air intake valve assembly through two steel wires, and the opening and closing of the one-way air intake valve assembly are controlled by the steel wires; two sets of wire harness rollers located above the one-way air intake valve assembly are fixed on the inner side wall of the air box body, and the steel wire is simultaneously limited between the two sets of wire harness rollers;

[0020] Among them, the one-way intake valve assembly includes an intake valve housing, a center of which is provided with an intake valve port, a control valve core located at the intake valve port is installed inside the intake valve housing, and the control valve core can completely block the intake valve port; the control valve core is slidably installed and fixed on a guide shaft 2 in the intake valve port, and a spring 2 is mounted on the guide shaft 2 to push the control valve core to move toward the intake valve port, and a steel wire is traction-connected to the control valve core.

[0021] The above scheme is adopted to accelerate the flow of air in the semi-encircled root air supply assembly. When there is no water flow impact in the water-jet transmission mechanism, the transmission swing arm is stationary and cannot press down the auxiliary push rod. At this time, under the elastic action of spring one, the steel wire is taut, and the control valve core is pulled by the steel wire to open the air inlet valve port. At this time, the one-way air inlet valve assembly is in an open state, so that air can flow naturally inside and outside the air box; when there is water flow impact in the water-jet transmission mechanism, the transmission swing arm rotates with the impeller, and the transmission swing arm presses down the auxiliary push rod when rotating. At this time, spring one is compressed, the steel wire is relaxed, and the control valve core closes the air inlet valve port under the elastic action of spring two. At this time, the one-way air inlet valve assembly is in a closed state, and the air can be compressed downward through the corrugated air plug, so that the air can flow quickly inside and outside the air box.

[0022] As a preferred embodiment of a root waterer for seedlings in the central dividing strip of a highway, the semi-annular root water supply assembly includes a linear water pipe, to which is connected a horizontally arranged semi-annular water pipe; the semi-annular water pipe is connected to a plurality of water supply pipes distributed in a circular array, and the water supply pipe has a plurality of water supply holes distributed in a linear array along its length; when the semi-annular root water supply assembly and the semi-annular root air supply assembly are plugged into each other, the water supply pipe and the air supply pipe are spaced and staggered with each other.

[0023] By adopting the above scheme, in order to achieve uniform water supply, water flows from the linear water pipe to each semi-circular water pipe, and then enters the water supply pipe. Finally, the water flows out from the water supply hole, so as to evenly supply water around the root system.

[0024] After adopting the above technical solution, the beneficial effects of the present invention are:

[0025] 1. First, the root waterer is provided with a semi-encircling root air supply assembly, and the outside air can directly pass through the root system of the seedlings through the semi-encircling root air supply assembly, so that the oxygen content around the root system is increased, which is conducive to the respiration of the root system. Therefore, when the root system is watered for a long time, the root system is not easy to rot, which is more conducive to the healthy growth of the seedlings; secondly, after the semi-encircling root water supply assembly of the root waterer is plugged into the semi-encircling root water supply assembly, the entire encircling root water supply assembly will be more stable, which can restrain the roots of the seedlings, thereby preventing them from extending outward and damaging the foundation of the highway; finally, when the root waterer is supplying water, there will be water flow impact in the water-flushing transmission mechanism, and the intermittent air acceleration flow mechanism can act through the water-flushing transmission mechanism to accelerate the fluidity of the air in the semi-encircling root air supply assembly, provide air with faster fluidity during water supply, further increase the oxygen content around the root system, and help the root system to breathe when absorbing water;

[0026] 2. In order to achieve uniform air supply, air is supplied from the linear air supply pipe to each semi-circular air supply pipe, and then enters the air supply pipe, and finally the air is discharged from the air supply hole, so as to evenly supply air around the root system;

[0027] 3. In order to store water around the root system, a water storage sponge segment is set up, and the excess water in the soil will be absorbed and stored by the water storage sponge segment, so as to facilitate the subsequent supply to the root system; and the water storage sponge segment is cut off one-third of its diameter along its radial direction to avoid the water storage sponge segment affecting the normal transportation of air;

[0028] 4. In order to realize the operation of the intermittent air acceleration flow mechanism, a water-jet transmission mechanism is provided. When there is water flow impact in the water-jet transmission mechanism, the transmission swing arm rotates with the impeller, and the transmission swing arm acts on the intermittent air acceleration flow mechanism, thereby realizing the operation of the intermittent air acceleration flow mechanism;

[0029] 5. In order to speed up the flow of air in the semi-encircled root air supply assembly, when there is no water flow impact in the water-jet transmission mechanism, the transmission swing arm is stationary and cannot press down the auxiliary push rod. At this time, under the elastic action of spring 1, the steel wire is tight, and the control valve core is pulled through the steel wire to open the air inlet valve port. At this time, the one-way air inlet valve assembly is in an open state, so that the air can flow naturally inside and outside the air box; when there is water flow impact in the water-jet transmission mechanism, the transmission swing arm rotates with the impeller, and the transmission swing arm presses down the auxiliary push rod when rotating. At this time, the spring 1 is compressed, the steel wire is relaxed, and the control valve core closes the air inlet valve port under the elastic action of spring 2.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figures 1 to 4 As shown, a root water supply device for seedlings in the central dividing strip of a highway comprises two semi-encircling root water supply assemblies 1 installed opposite to each other, and the two semi-encircling root water supply assemblies 1 can constitute a complete encircling root water supply assembly; a semi-encircling root air supply assembly 2 is also installed in each semi-encircling root water supply assembly 1, and the semi-encircling root water supply assembly 1 and the semi-encircling root air supply assembly 2 are buried underground; a main water supply pipe 103 is connected to the top of each semi-encircling root water supply assembly 1, and the main water supply pipe 103 is installed on the ground; each A water-flushing transmission mechanism 4 is installed between the main water supply pipe 103 and the semi-encircled root water supply assembly 1, and an intermittent air acceleration flow mechanism 5 is installed above each semi-encircled root air supply assembly 2; the water-flushing transmission mechanism 4 and the intermittent air acceleration flow mechanism 5 are located at the same height and transmit the action to the intermittent air acceleration flow mechanism 5. When there is water flow impact in the water-flushing transmission mechanism 4, the water-flushing transmission mechanism 4 can act on the intermittent air acceleration flow mechanism 5 to speed up the flow of air in the semi-encircled root air supply assembly 2.

[0051] Firstly, the root waterer is provided with a semi-circular root air supply assembly 2, so that the outside air can directly pass through the root system of the seedlings through the semi-circular root air supply assembly 2, so that the oxygen content around the root system is increased, which is helpful for the root system to respire. Therefore, when the root system is watered for a long time, the root system is not easy to rot, which is more conducive to the healthy growth of the seedlings; secondly, after the semi-circular root water supply assembly 1 of the root waterer is plugged into the semi-circular root water supply assembly 1, the entire circular root water supply assembly will be more stable, which can restrain the roots of the seedlings, thereby preventing them from extending outward and damaging the foundation of the highway; finally, when the root waterer is supplying water, there will be water flow impact in the water-flushing transmission mechanism 4, and the intermittent air acceleration flow mechanism 5 can act through the water-flushing transmission mechanism 4 to accelerate the fluidity of the air in the semi-circular root air supply assembly 2, providing air with faster fluidity when supplying water, further increasing the oxygen content around the root system, and helping the root system to breathe when absorbing water.

[0052] like Figure 5 As shown, the semi-circular root gas supply assembly 2 includes a linear gas pipe 201, to which multiple semi-circular gas pipes 202 arranged horizontally and arranged side by side in the upper and lower parts are connected; all the semi-circular gas pipes 202 are connected together with multiple gas supply pipes 203 arranged in a circumferential array, and multiple gas supply holes 204 arranged in a linear array along the length of the gas supply pipe 203 are provided. In order to achieve uniform gas supply, air is supplied from the linear gas pipe 201 to each semi-circular gas pipe 202, and then enters the gas supply pipe 203, and finally the air is discharged from the gas supply hole 204, so as to uniformly supply gas around the root system.

[0053] like Figure 6 to Figure 7As shown, the wall of the semi-encircling air delivery pipe 202 is provided with multiple grooves 205 distributed in a circumferential array, and each groove 205 is filled with a water storage sponge segment 206; wherein the water storage sponge segment 206 is cut off one-third of its diameter along its radial direction, and a vent hole 207 is opened through the center of the water storage sponge segment 206 along its radial direction. In order to store water around the root system, by providing the water storage sponge segment 206, excess water in the soil will be absorbed and stored by the water storage sponge segment 206, so as to facilitate the subsequent supply to the root system; and the water storage sponge segment 206 is cut off one-third of its diameter along its radial direction, so as to avoid the water storage sponge segment 206 affecting the normal air delivery.

[0054] like Figures 8 to 9 , Figure 12 to Figure 13 As shown, the water jet transmission mechanism 4 includes a water flow box 401, the interior of the water flow box 401 is rotatably connected to the impeller 402; a guide seat 403 located above the impeller 402 is fixed inside the water flow box 401; a transmission swing arm 404 that can rotate with the impeller 402 is fixedly installed outside the water flow box 401, and the length of the transmission swing arm 404 is greater than the length of the fan blade; wherein the guide seat 403 is inclined in a "slide-like" manner, and an opening eccentric to the side of the impeller 402 rotating shaft is opened at the bottom of the guide seat 403, and the lower side of the opening corresponds to the fan blade of the impeller 402. In order to realize the operation of the intermittent air acceleration flow mechanism 5, a water jet transmission mechanism 4 is set. When there is water flow impact in the water jet transmission mechanism 4, the transmission swing arm 404 rotates with the impeller 402, and the transmission swing arm 404 acts on the intermittent air acceleration flow mechanism 5, thereby realizing the operation of the intermittent air acceleration flow mechanism 5.

[0055] like Figure 10 to Figure 11 , Figure 14 to Figure 15 As shown, the intermittent air acceleration flow mechanism 5 includes an air box 501, a push block 502 that can move up and down is installed inside the air box 501, and a corrugated air plug 503 that is interference-fitted with the inner wall of the air box 501 is installed on the outer limit of the push block 502; a vertically arranged main push rod 504 is fixed above the push block 502; a guide seat 505 is fixed on the top of the main push rod 504, and the guide seat 505 is slidably installed on a guide shaft 505 fixed inside the air box 501. 06, a spring 507 is sleeved on the guide shaft 506 to push the guide seat 505 to move upward; an auxiliary push rod 508 is fixed on the side wall of the main push rod 504, which is horizontally arranged and penetrates the outside of the air box 501, and the auxiliary push rod 508 is located in a avoidance groove 509 vertically opened on the side wall of the air box 501; the auxiliary push rod 508 can conflict with the transmission swing arm 404 when rotating, and the auxiliary push rod 508 can be pressed down when conflicting with the transmission swing arm 404;

[0056] Among them, two mutually symmetrical one-way air intake valve assemblies 6 are also installed at the lower end of the air box 501, and the bottom of the push block 502 is respectively connected to the one-way air intake valve assembly 6 by two steel wires 510, and the opening and closing of the one-way air intake valve assembly 6 are controlled by the steel wires 510; two groups of wire tie rollers 511 located above the one-way air intake valve assembly 6 are fixed on the inner side wall of the air box 501, and the steel wire 510 is simultaneously limited between the two groups of wire tie rollers 511;

[0057] Among them, the one-way intake valve assembly 6 includes an intake valve shell 601, an intake valve port 602 is opened at the center of the intake valve shell 601, and a control valve core 603 located at the intake valve port 602 is installed inside the intake valve shell 601, and the control valve core 603 can completely block the intake valve port 602; the control valve core 603 is slidably installed and fixed on a guide shaft 2 604 inside the intake valve port 602, and the guide shaft 2 604 is sleeved with a spring 2 605 that pushes the control valve core 603 to move toward the intake valve port 602, and the steel wire 510 is traction-connected to the control valve core 603.

[0058] In order to speed up the flow of air in the semi-encircled root air supply assembly 2, when there is no water flow impact in the water-jet transmission mechanism 4, the transmission swing arm 404 is stationary and cannot press down the auxiliary push rod 508. At this time, under the elastic action of the spring 1 507, the steel wire 510 is tightened, and the control valve core 603 is pulled by the steel wire 510 to open the air inlet valve port 602. At this time, the one-way air inlet valve assembly 6 is in an open state, so that air can flow naturally inside and outside the air box 501; When there is water flow impact in the water-jet transmission mechanism 4, the transmission swing arm 404 rotates with the impeller 402. The transmission swing arm 404 will press down the auxiliary push rod 508 when rotating. At this time, the spring 1 507 is compressed, the steel wire 510 is relaxed, and the control valve core 603 closes the air intake valve port 602 under the elastic action of the spring 2 605. At this time, the one-way air intake valve assembly 6 is in a closed state, and the air will be compressed downward through the corrugated air plug 503, so that the air can circulate quickly inside and outside the air box 501.

[0059] like Fig.16 As shown, the semi-circular root water supply assembly 1 includes a linear water pipe 101, to which a horizontally arranged semi-circular water pipe 102 is connected; the semi-circular water pipe 102 is connected with a plurality of water supply pipes 103 distributed in a circumferential array, and the water supply pipe 103 is provided with a plurality of water supply holes 104 distributed in a linear array along its length; when the semi-circular root water supply assembly 1 and the semi-circular root air supply assembly 2 are plugged into each other, the water supply pipe 103 and the air supply pipe 203 are staggered and spaced from each other. In order to achieve uniform water supply, water flows from the linear water pipe 101 to each semi-circular water pipe 102, and then enters the water supply pipe 103, and finally the water flows out from the water supply hole 104, so as to uniformly supply water around the root system.

[0060] Working principle of the present invention:

[0061] The root waterer is used to supply water and air to seedlings in the central dividing strip of expressways.

[0062] When in use, first connect the semi-circular root water supply component 1 and the semi-circular root air supply component 2 to each other, and then set the two sets of connected semi-circular root water supply components 1 and semi-circular root air supply components 2 opposite to each other to form a complete encircling water supply and air supply device, and then bury the semi-circular root water supply component 1 and the semi-circular root air supply component 2 together in the ground where the seedlings are located.

[0063] When there is no water supply, such as Figures 8 to 11 As shown, there is no water flow impact in the water-flushing transmission mechanism 4. At this time, the transmission swing arm 404 is stationary and cannot press down the auxiliary push rod 508. At this time, under the elastic action of the spring 507, the steel wire 510 is tightened, and the control valve core 603 is pulled by the steel wire 510 to open the air intake valve port 602. At this time, the one-way air intake valve assembly 6 is in an open state, so that air can flow naturally inside and outside the air box 501. At this time, the roots can be exposed to the naturally flowing air, which increases the oxygen content around the roots, making the roots less likely to rot, and is more conducive to the healthy growth of seedlings.

[0064] When water is supplied, Figures 12 to 15 As shown, there is water flow impact in the water-jet transmission mechanism 4, and the transmission swing arm 404 rotates with the impeller 402. The transmission swing arm 404 will press down the auxiliary push rod 508 when rotating. At this time, the spring 1 507 is compressed, the steel wire 510 is relaxed, and the control valve core 603 closes the air inlet valve port 602 under the elastic action of the spring 2 605. At this time, the one-way air inlet valve assembly 6 is in a closed state, and the air will be compressed downward through the corrugated air plug 503, and this cycle is repeated, so that the air can circulate quickly inside and outside the air box 501. At this time, the roots can be exposed to the air that accelerates the natural flow, further increasing the oxygen content around the roots, and helping the roots to breathe when absorbing water.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
