Description

Technical Field

[0001] The invention relates to the technical field of garden irrigation devices, and in particular to a garden seedling watering device. Background Art

[0002] In modern society, with the acceleration of urbanization and the improvement of people's environmental awareness, garden construction has received more and more attention and has become an important part of urban construction and ecological environment improvement. The large-scale emergence of gardens has made irrigation technology a focus of many people. By keeping the ground moist through reasonable irrigation, it can not only prevent garden seedlings from losing water, but also regulate the surface temperature and prevent sunburn.

[0003] The rooting and germination of seedlings require a large amount of water, especially when they have just begun to expand their leaves but have not yet fully taken root (the pseudo-active stage). The transpiration from the leaves is large and the soil moisture supply is small. Once the water supply is cut off, the plants will die. Timely irrigation is the key.

[0004] For watering seedlings, it is generally required to irrigate more times with less water each time. Drip irrigation can just meet the water requirements of seedlings. Drip irrigation is to drip water and the moisture and nutrients needed by plant seedlings evenly and slowly into the soil in the root zone of seedlings through a pipeline system and an emitter installed on a branch pipe. However, in the actual operation process, due to the existence of human operation errors, the actual planting row spacing of seedlings and the spacing of branch pipes in the pipeline system cannot correspond one-to-one, making it impossible for the branch pipes to accurately cover the root zone soil of the seedlings. It is necessary to adjust the position of the branch pipes according to the actual planting row spacing of the seedlings. In the traditional pipeline system, the branch pipes are always connected to the main pipeline at a fixed spacing. Therefore, there is a disadvantage that the branch pipes cannot correspond one-to-one with the seedling planting rows in real time. Summary of the invention

[0005] The purpose of the present invention is to provide a garden seedling watering device, which is based on setting a square seat with a spacing several times smaller than the row spacing of the garden seedlings and a semicircular water permeable hole. The semicircular water permeable hole and the semicircular plug are connected or disconnected by utilizing the different connections formed by the flipping state of the dual-purpose cannula assembly and the main water pipe, so that the branch pipe connecting component connected to the dual-purpose cannula assembly can be conveniently adjusted to the position corresponding to the seedling planting row, and the branch pipe connecting component is not only quickly connected with the dual-purpose cannula assembly before water supply, but also can be safely locked with the dual-purpose cannula assembly during water supply.

[0006] The object of the present invention is achieved through such a technical solution, a garden seedling watering device, comprising a main pipe component, a dual-purpose cannula assembly and a branch pipe connecting component, the main pipe component comprises a main water pipe, the dual-purpose cannula assembly comprises a buckle and a semicircular plug, and the branch pipe connecting component comprises a pressure stabilizing cylinder, a water hole, a piston rod and a plug-in connecting pipe;

[0007] The side wall of the main water pipe is arranged with square seats at certain intervals, and each group of square seats is provided with a semicircular water-permeable hole penetrating the inner wall of the main water pipe. An inner connecting pipe is fixed to one end of the buckle, and the semicircular plug is connected to the inner end surface of the inner connecting pipe. A dual-purpose clamping seat is fixed to the outer wall of the inner connecting pipe. The semicircular plug can be connected and disconnected with the semicircular water-permeable hole by turning over the buckle in coordination with the disassembly and assembly of the other end of the buckle and the positioning clamping of the dual-purpose clamping seat to the square seats.

[0008] The pressure-stabilizing cylinder is laterally connected and fixed in the middle part of the main body of the inner connecting tube, and the water-through hole is opened in the middle part of the pressure-stabilizing cylinder and is opposite to the semicircular plug. The inside of the pressure-stabilizing cylinder is also symmetrically fixed with inner clamping rings, and an inner piston is slidably connected inwardly in the cavity composed of each group of inner clamping rings and the pressure-stabilizing cylinder. The piston rod is connected and fixed to the outer end surface of the inner piston, and the head end of the plug-in connecting tube is symmetrically fixed with an inner C-shaped clamp, and after the head end of the plug-in connecting tube is inserted into the inner connecting tube and is in place, the inner C-shaped clamp can be elastically clamped on the outside of the pressure-stabilizing cylinder, and elastic insertion holes are symmetrically opened on both sides of the head end of the plug-in connecting tube, and after the semicircular plug and the semicircular water-permeable hole are connected and water is passed, the water pressure can push the inner piston to insert the piston rod into the elastic insertion hole.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] The spacing of the square seats in the side wall of the main water pipe is several times smaller than the row spacing of the garden seedlings, so that in the actual operation process, the branch pipe connecting component connected to the dual-purpose plug assembly can be plugged into the position facing the garden seedling planting row;

[0011] Furthermore, since the buckle can form a stable connection between the outer wall of the main water pipe and the square seat when it is turned over, and the semicircular plug and the semicircular water permeable hole can be connected or disconnected by turning the buckle, when it is necessary to use the dual-use cannula assembly facing the garden seedling planting row, the buckle can be turned over to connect the semicircular plug and the semicircular water permeable hole;

[0012] The head end of the plug-in connecting pipe can also be inserted into the interior of the inner connecting pipe, so that the inner C-shaped card is elastically connected to the pressure-stabilizing cylinder, so that the branch pipe connecting component and the dual-use plug-in pipe assembly in the use state can form a preliminary connection;

[0013] The end of each group of plug-in connecting pipes is connected to an irrigation pipeline corresponding to the seedling planting row, and the irrigation pipeline is connected to a water outlet corresponding to the plant spacing;

[0014] After water from the outside enters the main water pipe, it will enter the inner connecting pipe through the channel formed by the semicircular water permeable hole and the semicircular plug, and enter the interior of the pressure-stabilizing cylinder through the water hole. Due to the effect of water pressure, it will push the symmetrically distributed inner pistons to move outward, driving the piston rod to move outward, so that the piston rod can be inserted into the opposite spring-insertion hole.

[0015] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0016] (1) The present invention is designed with the spacing of the square seats in the side wall of the main water pipe being several times smaller than the row spacing of the garden seedlings. The purpose is to solve the problem that the actual row spacing of the garden seedlings and the irrigation water supply pipeline separated from the main water pipe are skewed or misaligned. Based on the semicircular water holes opened in the square seats connected to the side wall of the main water pipe and the semicircular plug connected to the inner end face of the inner connecting pipe, the semicircular plug and the semicircular water holes can be turned on and off by flipping the buckle. The buckle in actual use state can be flipped to the position where the semicircular plug and the semicircular water hole are connected. The operation is simple and can meet the actual irrigation work of each planting row of garden seedlings. There is no need to add valves and irrigation water supply pipelines, which saves costs.

[0017] (2) In the present invention, a pressure stabilizing cylinder is also fixed transversely in the main body of the inner connecting pipe. One of the purposes of providing the pressure stabilizing cylinder is to utilize the inner cavity of the pressure stabilizing cylinder and the inner piston that elastically slides in the inner cavity of the pressure stabilizing cylinder to achieve the effect of stabilizing the water pressure of the water source entering the inner connecting pipe;

[0018] (3) At the same time, another purpose of providing the pressure stabilizing cylinder is that when the plug-in connecting tube is connected to the inner connecting tube, the normal water pressure supplied by the inner connecting tube to the plug-in connecting tube can push the piston rod to move outward and insert it into the spring insertion hole, so that when the plug-in connecting tube is used, it can form a safe connection with the inner connecting tube;

[0019] (4) In addition, the present invention also symmetrically connects an inner C-shaped clip to the head end of the plug-in connecting pipe. The purpose of providing the inner C-shaped clip is that after the plug-in connecting pipe is inserted into the inner connecting pipe and installed in place, the inner C-shaped clip can form an elastic clamping effect with the pressure-stabilizing cylinder in the middle of the inner connecting pipe body, so that the plug-in connecting pipe will not easily fall off from the inner connecting pipe when no water is supplied.

[0043] like Figure 1-Figure 12As shown, a garden seedling watering device, the side wall of the main water pipe 101 in the main pipe component 1 is arranged with square seats 104 at a certain interval, each group of square seats 104 is provided with a semicircular water-permeable hole 105 that penetrates the inner wall of the main water pipe 101, one end of the buckle 402 is fixed with an inner connecting pipe 408, a semicircular plug 409 is connected to the inner end surface of the inner connecting pipe 408 and communicates with the inside of the inner connecting pipe 408, and a dual-purpose clamping seat 411 is fixed to the outer wall of the inner connecting pipe 408, and the dual-purpose clamping seat 411 is located in the inner circle of the buckle 402, and cooperates with the disassembly and assembly of the other end of the buckle 402, and the positioning clamping connection of the dual-purpose clamping seat 411 to the square seat 104, by flipping the buckle 402, the semicircular plug 409 can form a connection and disconnection with the semicircular water-permeable hole 105;

[0044] The pressure-stabilizing cylinder 501 is laterally connected to the middle of the main body of the inner connecting tube 408, and the water hole 502 is opened in the middle of the pressure-stabilizing cylinder 501 and is opposite to the semicircular plug 409. The inner clamping ring 503 is symmetrically fixed inside the pressure-stabilizing cylinder 501, and the inner clamping ring 503 is outside the opening range of the water hole 502. In the cavity formed by each group of inner clamping rings 503 and the pressure-stabilizing cylinder 501, there is an inner piston 504 that slides inwardly, and the piston rod 505 is connected to the outer end surface of the inner piston 504. The head end of the plug-in connecting tube 508 is symmetrically fixed with an inner C-shaped card 512, and after the head end of the plug-in connecting tube 508 is inserted into the inner connecting tube 408 and is in place, the inner C-shaped card 512 can be elastically clamped on the outside of the pressure-stabilizing cylinder 501, and spring-insertion holes 513 are symmetrically opened on both sides of the head end of the plug-in connecting tube 508, and after the semicircular plug 409 is connected to the semicircular water-permeable hole 105 and water is passed through, the water pressure can push the inner piston 504 to insert the piston rod 505 into the spring-insertion hole 513.

[0045] Here’s how it works:

[0046] The external water supply source is connected to the main water pipe 101, and the spacing of the square seats 104 in the side wall of the main water pipe 101 is several times smaller than the row spacing of the garden seedlings, so that in the actual operation process, the branch pipe connecting member 5 connected to the dual-purpose cannula assembly 4 can be plugged into the position facing the garden seedling planting row;

[0047] And because the buckle 402 can form a stable connection between the outer wall of the main water pipe 101 and the square seat 104 when it is turned over, at the same time, by turning over the buckle 402, the semicircular plug 409 and the semicircular water permeable hole 105 can be connected or disconnected. Therefore, when it is necessary to use the dual-purpose cannula assembly 4 facing the garden seedling planting row, the buckle 402 is turned over until the semicircular plug 409 is connected to the semicircular water permeable hole 105. It should be noted that the turning over of the buckle 402 is manually adjusted according to needs, that is, the buckle 402 is rotated 180° perpendicular to the main water pipe 101 as the axis and then clamped on the main water pipe 101 again, so that the semicircular plug 409 can be connected with the semicircular water permeable hole 105.

[0048] The head end of the plug-in connecting tube 508 can be inserted into the inner connecting tube 408, so that the inner C-shaped clamp 512 is elastically clamped into the pressure-stabilizing cylinder 501, so that the branch pipe connecting member 5 can form a preliminary connection with the dual-use cannula assembly 4 in the use state;

[0049] The end of each set of plug-in connecting pipes 508 is connected to an irrigation pipeline corresponding to the seedling planting row, and the irrigation pipeline is connected to a water outlet corresponding to the plant spacing;

[0050] After the water from the outside enters the main water pipe 101, it will enter the inner connecting pipe 408 through the channel formed by the semicircular water permeable hole 105 and the semicircular plug 409, and flow through the water hole 502 to enter the interior of the pressure-stabilizing cylinder 501. Due to the effect of water pressure, the symmetrically distributed inner pistons 504 will be pushed outward, driving the piston rod 505 to move outward, so that the piston rod 505 can be inserted into the opposite spring insertion hole 513;

[0051] That is to say, when the plug-in connecting pipe 508 is connected to the inner connecting pipe 408 and used as an irrigation water supply pipeline, the piston rod 505 can be inserted into the spring insertion hole 513 to achieve a safe and stable connection between the plug-in connecting pipe 508 and the pressure stabilizing cylinder 501;

[0052] The other unused dual-purpose cannula assemblies 4 are in a state where the buckle 402 is flipped over to the semicircular plug 409 and is disconnected from the semicircular water-permeable hole 105 .

[0053] The specific structure of the main component 1 is as follows Figure 2 and Figure 3 As shown, a water inlet elbow 102 is connected to the middle of the main body of the main water pipe 101, and a water inlet valve 103 is installed in the water inlet elbow 102;

[0054] A circular insertion hole 106 is also provided in the middle of the outer end surface of the square seat 104 , and the opening radius of the circular insertion hole 106 is greater than the opening radius of the semicircular water-permeable hole 105 .

[0055] The specific structure of the dual-purpose cannula assembly 4 is as follows Figure 4, Figure 5 and Figure 6 As shown, the sealing flat gasket 401 is fixedly connected to the inner bottom surface of the round plug hole 106 and does not intersect with the semicircular water-permeable hole 105;

[0056] When the semicircular plug 409 is disconnected from the semicircular water-permeable hole 105, the semicircular plug 409 just contacts and abuts against the sealing flat gasket 401, and the sealing flat gasket 401 can achieve a sealing effect on the entrance of the semicircular plug 409;

[0057] The other end of the buckle 402 is an open structure, a slot 403 is provided at the other end of the buckle 402, an insert 404 is also fixed to the other end of the buckle 402, and the insert 404 can be inserted into the slot 403, an inner lock seat 406 is fixed to the outside of the insert 404, an adjustment slot 407 is provided in the inner lock seat 406, side lock seats 405 are symmetrically provided on both sides of the slot 403, and the side lock seats 405 are fixed to the outside of the other end of the buckle 402; it should be noted that the buckle 402 is an integrally formed material with a certain toughness, such as TPU, EVA and the like, so as to ensure that the opening structure can open a sufficiently large opening, so as to be easily stuck on the outer wall of the main water pipe 101;

[0058] A fixed connection can be formed between the inner lock seat 406 and the two sets of side lock seats 405 by standard bolts and nuts, and the degree of locking connection between the buckle 402 and the square seat 104 and the main water pipe 101 can be adjusted by moving the bolts in the adjustment slot 407;

[0059] The plug-in sealing ring 410 is fixed to the inner end surface of the inner connecting tube 408, and after the inner connecting tube 408 is inserted into the round plug hole 106, the plug-in sealing ring 410 forms a sealing connection with the inner bottom surface of the round plug hole 106;

[0060] The sealing connection formed by inserting the sealing ring 410 can also ensure that when the semicircular plug 409 is connected to the semicircular water hole 105, the water source can only flow from the semicircular water hole 105 into the semicircular plug 409, and will not be discharged from other positions;

[0061] The two sides of the buckle 402 are respectively engraved with a water-on mark 412 and a water-off mark 413. When the semicircular plug 409 is connected to the semicircular water-permeable hole 105, the water-on mark 412 faces upward, and when the semicircular plug 409 is disconnected from the semicircular water-permeable hole 105, the water-off mark 413 faces upward, so that the operator can visually inspect and perform the correct flipping operation on the buckle 402.

[0062] The specific structure of the branch pipe connecting member 5 is as follows: Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the outer sleeve 506 is symmetrically fixedly connected to the outer end opening of the pressure-stabilizing cylinder 501, and the piston rod 505 is slidably connected in the outer sleeve 506. A compression spring 516 is sleeved and installed in each group of piston rods 505. One end of the compression spring 516 is clamped on the side of the outer sleeve 506, and the other end is clamped on the side of the inner piston 504. The compression spring 516 can form an elastic support effect on the inner piston 504 inward;

[0063] The side card slots 507 are symmetrically arranged on both sides of one end of the buckle 402, and a card seat 509 is fixed on the outer wall of the plug-in connecting tube 508. A side card post 510 is symmetrically fixed on one side of the card seat 509. The plug-in sliding fit formed between the side card post 510 and the side card slots 507 can guide the plug-in connecting tube 508 to be inserted into the inner connecting tube 408, thereby preventing the plug-in connecting tube 508 from twisting during the insertion process, which may cause the problem that the inner C-shaped card 512 cannot be accurately inserted into the outer wall of the voltage-stabilizing cylinder 501.

[0064] The elastic insertion hole 513 is provided at the middle of the head end of the side clamp column 510, the inner operation groove 511 is symmetrically provided at the head end of the plug-in connecting tube 508, and the inner end of the inner C-shaped clamp 512 is fixedly connected to the inner operation groove 511. By providing the inner operation groove 511, space can be provided for the elastic deformation of the inner C-shaped clamp 512;

[0065] A branch pipe connection sealing ring 515 is fixedly installed at the outer end of the inner connecting tube 408, and a sealing pressure ring 514 is fixedly connected between the front end of the socket 509 and the outer wall of the plug-in connecting tube 508. After the head end of the plug-in connecting tube 508 is inserted into the inner connecting tube 408 and is in place, the sealing pressure ring 514 contacts and abuts against the branch pipe connection sealing ring 515 to form a sealing effect.

[0066] Branch pipe watering components used for watering each garden seedling Fig.11 and Fig.12 As shown, the branch pipe 601 is connected to one end of the outlet of the plug-in connecting pipe 508, and a branch pipe valve 602 is also installed in the inlet pipeline of the branch pipe 601;

[0067] The water outlet seat 603 is fixedly connected to the side wall of the branch pipe 601 according to the spacing arrangement of the garden seedlings;

[0068] The inner end of the watering connecting seat 604 is fixedly connected with a connecting seat connecting pipe 605, and the inner end of the connecting seat connecting pipe 605 is fixedly connected with a head seat 606 whose outer diameter is larger than that of the connecting seat connecting pipe 605. The sealing ring 607 is sleeved and fixed on the outside of the head seat 606. The head seat 606 can be inserted into the inner hole of the water outlet seat 603, and forms a sealed connection with the inner hole of the water outlet seat 603 through the sealing ring 607;

[0069] A water cylinder 608 is fixedly connected to the cavity of the watering seat 604, and the water cylinder 608, the seat and pipe 605 and the head seat 606 are in water communication. The watering head 609 is threadedly connected to the watering seat 604, and the conical column 610 is fixedly connected to the middle of the inner cavity of the watering head 609 and inserted into the inner hole of the water cylinder 608;

[0070] A slow-flow water outlet cylinder 611 is also fixed in the middle of the inner cavity of the watering head 609, and the water cylinder 608 is inserted into the slow-flow water outlet cylinder 611. A water outlet hole 612 communicating with the inner cavity is opened in the outer end body of the watering head 609;

[0071] By screwing the irrigation head 609, the conical column 610 and the water cylinder 608 can be moved relative to each other. When the conical column 610 moves toward the water cylinder 608, the gap between the outer surface of the conical column 610 and the inner hole of the water cylinder 608 decreases. When the conical column 610 moves away from the water cylinder 608, the gap between the outer surface of the conical column 610 and the inner hole of the water cylinder 608 increases. Thus, by screwing the irrigation head 609, the flow rate of water source passing through the inner hole of the water cylinder 608 and the outer surface of the conical column 610 can be adjusted.

[0072] The purpose of setting the slow-flow water outlet 611 is to prevent the water flowing out from the inner hole of the water tube 608 and the outer surface of the conical column 610 from flowing out directly from the water outlet 612, but to block and reflect the water outlet 611 before flowing out through the water outlet 612, which can slow down the dripping speed of irrigation per unit time to a certain extent, thereby achieving the purpose of water saving;

[0073] The main body of the water outlet seat 603 is also provided with a latch hole 613 connected to the inner hole of the water outlet seat 603. After the head seat 606 is inserted into the inner hole of the water outlet seat 603, the latch 614 is inserted into the latch hole 613, and the latch 614 can be used to snap onto the outside of the connecting seat and connecting pipe 605, thereby forming a safe connection between the head seat 606 and the water outlet seat 603.

[0074] Furthermore, since the plug buckle 614 is pluggable, it can not only form a safe connection between the head seat 606 and the water outlet seat 603, but also realize the rapid disassembly of the head seat 606 and the water outlet seat 603.

[0075] A water reservoir 2 is also provided on one side of the main pipe component 1, and the water inlet end of the water inlet elbow 102 is connected to the water channel of the water reservoir 2. A water pump is also installed in the pipeline connecting the water inlet elbow 102 and the water reservoir 2, so that the water reservoir 2 can supply water to the main pipe component 1. An electric control box 3 is also provided on one side of the water reservoir 2, and the water inlet valve 103 and the branch pipe valve 602 are both electrically connected to the electric control box 3, and the electric control box 3 can automatically control the opening and closing of the water inlet valve 103 and the branch pipe valve 602;

[0076] A temperature and humidity sensor 7 is also provided on one side of each group of branch pipes 601. The temperature and humidity sensor 7 is electrically connected to the electric control box 3 and is mainly used for real-time monitoring of garden seedlings in different planting rows. The number of temperature and humidity sensors 7 can be increased or decreased according to the number of garden seedlings in different planting rows, so as to more accurately monitor the garden seedlings in different planting rows. When the temperature and humidity sensor 7 detects that the temperature and humidity of the corresponding garden seedling planting row is lower than the lower limit setting value, it will be judged as water shortage. At this time, the temperature and humidity sensor 7 will automatically start the branch pipe valve 602 corresponding to the group of garden seedling planting rows;

[0077] After the branch valve 602 is opened, the water source in the main water pipe 101 will enter the semicircular plug 409 from the semicircular permeable hole 105, and enter the plug-in connecting pipe 508 from the inner connecting pipe 408. After filling the branch pipe 601, it will slowly flow out from the water outlet holes 612 opened in each group of watering heads 609, so as to achieve the purpose of watering the garden seedlings.

[0078] Similarly, when the temperature and humidity sensor 7 detects that the temperature and humidity of the garden seedling planting row has reached the upper limit setting value, the branch valve 602 of the group will be automatically closed, and when it is lower than the lower limit setting value, the branch valve 602 of the group will be automatically opened, thereby realizing the automatic watering of garden seedlings in different planting rows. In addition, the switch of the branch valve 602 can also be remotely controlled, which is a prior art and will not be described in detail.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
