Description

Technical Field

[0001] This utility model relates to the field of vegetable seedling technology, and in particular to a water supply device for vegetable seedling cultivation. Background Technology

[0002] In modern agricultural production, vegetable seedling raising is a crucial step in ensuring crop survival rates and increasing yields, placing high demands on environmental conditions, especially water management. To meet the needs of precise water control and efficient water supply during seedling raising, various water replenishment devices are widely used in greenhouse seedling operations.

[0003] The existing patent "CN 222548185 U A Vegetable Seedling Water Supply Device" uses a sorting mechanism to retract and extend the connecting hose and connecting wire when the mobile trolley moves, and then uses the water supply pipe to supply water. Because the water supply pipe adopts a fixed distance water supply arrangement, it can only work in a single-width greenhouse and is difficult to flexibly adapt to the water supply needs of greenhouses of different widths. Secondly, the overall structure of the water supply pipe is not foldable, making it difficult to pass through greenhouse doors and other passages, and thus unable to carry out cross-area operations.

[0004] Therefore, it is necessary to provide a water supply device for vegetable seedling cultivation to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the aforementioned problems, this application provides a water replenishment device for vegetable seedling cultivation, thereby solving the issues raised in the background art, which limit water replenishment to vegetable seedlings to a single width of greenhouse and prevent cross-regional operations.

[0006] To achieve the objectives of this application, the following technical solution is provided:

[0007] This application provides a water supply device for vegetable seedling cultivation, comprising:

[0008] The greenhouses are configured in multiple units and arranged in a row. Each greenhouse is equipped with a closed door, and the lower end of each closed door is covered with a soft curtain.

[0009] Two tracks are configured and laid on the ground within the row of greenhouses. Limiting posts are fixedly installed on the ground at both ends of the tracks, and the tracks pass through the closed doors between adjacent greenhouses. The upper end of each track is flush with the lower end of the closed door.

[0010] An RGV trolley is movably mounted on the track, and a foldable water replenishment mechanism is installed at one end of the RGV trolley in the direction of travel; and

[0011] The pipe retraction mechanism is installed inside the shed at the head of the RGV trolley in the direction of travel, and the pipe retraction mechanism is detachably connected to the foldable water replenishment mechanism.

[0012] In one possible implementation, a handrail is fixedly provided on the upper end of the RGV trolley side away from the foldable water replenishment mechanism.

[0013] In one possible implementation, the foldable water replenishment mechanism includes:

[0014] A bracket is fixedly installed at one end of the RGV trolley in the direction of travel. A bracket is fixedly installed at the end of the bracket away from the RGV trolley. A bogie is rotatably installed on both sides of the bracket away from the bracket. An ear seat is fixedly installed at the end of the bogie away from the RGV trolley, and a support rod is fixedly installed at the bottom of the bogie.

[0015] Two guide pipes are configured symmetrically on both sides of the support, and each guide pipe is equipped with a valve body. Multiple nozzles are evenly installed on the guide pipe located at the lower end of the support rod. Each nozzle has a clamp fixedly attached to its upper end, and the clamps are fixedly attached to the support rod.

[0016] Two mounting plates are configured and symmetrically fixed at one end of the bracket away from the support. Hydraulic cylinders are rotatably mounted on the outer sides of both mounting plates, and the output ends of the hydraulic cylinders are hinged to the lugs.

[0017] In one possible implementation, both of the guide tubes are fixedly connected to the output end of the vacuum self-priming pump, and the outer end of the input end of the vacuum self-priming pump is provided with an external thread in the circumferential direction.

[0018] In one possible implementation, the tube delivery and take-up mechanism includes:

[0019] The cabinet has a rotatable winding wheel inside, on which a connecting pipe is wound, and a driven sprocket is coaxially fixed on one side of the winding wheel; and

[0020] A forward and reverse motor is fixedly installed inside the cabinet, and a drive sprocket is fixedly installed circumferentially at the output end of the forward and reverse motor. The drive sprocket is connected to the driven sprocket through a chain.

[0021] In one possible implementation, the RGV trolley is equipped with a controller, a battery, and a drive mechanism for driving the RGV trolley to move forward and backward along the track. The controller is connected to the battery and the hydraulic cylinder, respectively. The forward and reverse motors are connected to the control unit, and the controller is synchronously connected to the control unit, the drive mechanism, and the vacuum self-priming pump.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means three or more.

[0036] Figures 1-5 A water supply device for vegetable seedling cultivation provided in this application embodiment includes:

[0037] The greenhouses are configured in multiple units and arranged in a row. Each greenhouse is equipped with a closed door, and the lower end of each closed door is covered with a soft curtain.

[0038] Track 1 is configured as two tracks, which are laid on the ground inside the row of greenhouses. Limiting posts 2 are fixedly installed on the ground at both ends of the track 1, and the track 1 passes through the closed door between adjacent greenhouses. The upper end of the track 1 is flush with the lower end of the closed door.

[0039] An RGV trolley 3 is movably mounted on the track 1, and a foldable water replenishment mechanism 4 is installed at one end of the RGV trolley 3 in the direction of travel; and

[0040] The pipe retraction mechanism 5 is installed inside the shed at the head end of the RGV trolley 3 in the direction of travel, and the pipe retraction mechanism 5 is detachably connected to the foldable water replenishment mechanism 4.

[0041] It should be added that the distance between the seedling area at both ends of each greenhouse and the closed door is equal, and the distance between each greenhouse is equal. After the closed door closes the greenhouse, a gap is formed between the closed door and track 1. At this time, a soft curtain can be placed on track 1 and soil can be covered on the soft curtain to ensure the temperature and humidity inside the greenhouse. When the closed door needs to be opened, the soil can be pushed to other positions and then the closed door can be opened. In addition, the RGV trolley 3 is existing technology and will not be described in detail.

[0042] Using the above technical solution, the pipe retraction mechanism 5 is first connected to the foldable water replenishment mechanism 4. The opening angle of the foldable water replenishment mechanism 4 is adjusted according to the width of the greenhouse. Then, the moving distance and speed of the RGV trolley 3 are set according to the length of the greenhouse. The foldable water replenishment mechanism 4 and the pipe retraction mechanism 5 are started simultaneously. The RGV trolley 3 moves along the track 1 while replenishing water to the vegetable seedlings in the greenhouse. When the RGV trolley 3 moves to a fixed distance, it stops. The foldable water replenishment mechanism 4 is controlled to return to its initial state. The closed door of the greenhouse on this side and the closed door of the adjacent greenhouse are opened. The RGV trolley 3 is pushed to move along the sealed door and the track 1 to the next greenhouse. The above steps are repeated to replenish water until the water replenishment work in the last greenhouse in the single row is completed.

[0043] Based on the above technical solution, the foldable water replenishment mechanism 4 can be adjusted according to the width of the greenhouse to make it compatible with the width of the greenhouse and replenish water to the vegetable seedlings in the greenhouse as the RGV trolley 3 moves. This allows users to adjust the position of the foldable water replenishment mechanism 4 according to the specific width and layout of each greenhouse, ensuring uniform and comprehensive spraying and avoiding spraying blind spots or overlapping areas caused by fixed structures, thus improving the versatility and applicability of the device.

[0044] In one possible implementation, a handrail 6 is fixedly provided on the upper end of the RGV trolley 3 on the side away from the foldable water replenishment mechanism 4, and the RGV trolley 3 can be pushed to move along the track 1 by the handrail 6.

[0045] In one possible implementation, the foldable water replenishment mechanism 4 includes:

[0046] A bracket 401 is fixedly installed at one end of the RGV trolley 3 in the direction of travel. A bracket 402 is fixedly installed at the end of the bracket 401 away from the RGV trolley 3. A bogie 403 is rotatably installed on both sides of the end of the bracket 402 away from the bracket 401. A lug 411 is fixedly installed at the end of the bogie 403 away from the RGV trolley 3. A support rod 404 is fixedly installed at the bottom of the bogie 403.

[0047] Two guide pipes 405 are configured symmetrically on both sides of the bracket 401. Each guide pipe 405 is equipped with a valve body 406. Multiple nozzles 407 are evenly mounted on the guide pipe 405 located at the lower end of the support rod 404. Each nozzle 407 has a clamp 408 fixedly mounted on its upper end, and the clamps 408 are fixedly mounted to the support rod 404.

[0048] Mounting plates 409 are configured in two, and are symmetrically fixed at one end of the bracket 402 away from the support 401. Hydraulic cylinders 410 are rotatably mounted on the outer side of both mounting plates 409, and the output ends of the hydraulic cylinders 410 are hinged to the lugs 411.

[0049] In one possible implementation, both of the guide pipes 405 are fixedly connected to the output end of the vacuum self-priming pump 412, and the outer end of the input end of the vacuum self-priming pump 412 is provided with an external thread in the circumferential direction.

[0050] Using the above technical solution, the pipe retraction mechanism 5 is first connected to the vacuum self-priming pump 412. According to the width of the greenhouse, the hydraulic cylinder 410 is adjusted, the bogie 403 deflects on the bracket 402, and the angle of the bogie 403 is adjusted to match the width of the greenhouse. After the vacuum self-priming pump 412 is started, the vacuum self-priming pump 412 supplies water to each nozzle 407 along the pipe retraction mechanism 5 and the guide pipe 405. During the movement of the RGV trolley 3, it can ensure that the spraying of the nozzles 407 is uniform and comprehensive. When the RGV trolley 3 is moved from one greenhouse to the next, the bogie 403 can be controlled to move towards each other (closer) and fold, which is conducive to the transfer of the whole device through narrow channels. Thus, the continuous water replenishment task between multiple greenhouses can be completed, improving work efficiency.

[0051] In one possible implementation, the tube receiving and releasing mechanism 5 includes:

[0052] The cabinet 51 has a rotatable winding wheel 52 inside, on which a connecting pipe 53 is wound, and a driven sprocket 54 is coaxially fixed on one side of the winding wheel 52; and

[0053] A forward and reverse motor 55 is fixedly installed inside the cabinet 51, and a drive sprocket 56 is fixedly installed circumferentially at the output end of the forward and reverse motor 55. The drive sprocket 56 is connected to the driven sprocket 54 through a chain 57.

[0054] It should be added that a brake is installed on the cabinet 51 (this is existing technology and will not be described in detail). The brake can be used to brake the winding wheel 52, thereby effectively preventing the connecting tube 53 from unwinding. That is, after the forward and reverse motor 55 is started, the brake is closed. The forward and reverse motor 55 drives the driven sprocket 54 to rotate through the drive sprocket 56 and the chain 57, and performs winding and unwinding work on the connecting tube 53. During this process, it can prevent the connecting tube 53 from getting tangled and knotted, and also prevent the connecting tube 53 from affecting the movement of the RGV trolley 3. After each winding and unwinding operation is completed, the brake is activated again to prevent the connecting tube 53 from unwinding.

[0055] In one possible implementation, the RGV trolley 3 is equipped with a controller, a battery, and a drive mechanism for driving the RGV trolley 3 to move forward and backward along the track 1. The controller is connected to the battery and the hydraulic cylinder 410, respectively. The forward and reverse motor 55 is connected to the control unit, and the controller is synchronously connected to the control unit, the drive mechanism, and the vacuum self-priming pump 412.

[0056] It should be noted that, on the one hand, the lower controller can control the extension and retraction of the hydraulic cylinder 410, and on the other hand, the lower controller is connected to the control unit. Through the controller, the forward and reverse rotation and start and stop of the forward and reverse motor 55 can be indirectly controlled by the control unit. At the same time, the forward and reverse rotation and start and stop of the drive mechanism and the pump pressure and start and stop of the vacuum self-priming pump 412 can be controlled by the controller. The controller can also synchronously control the start of the forward and reverse motor 55, the drive mechanism and the vacuum self-priming pump 412. When the forward and reverse motor 55 starts, the brake is closed, and when the forward and reverse motor 55 is closed, the brake is activated.

[0057] Through the above technical solution, after setting the moving distance and speed of the RGV trolley 3 according to the length of the greenhouse, during the process of the RGV trolley 3 moving from the water replenishment starting point to the water replenishment endpoint of the greenhouse, the controller synchronously controls the start of the forward and reverse motor 55, the drive mechanism and the vacuum self-priming pump 412. That is, when the drive mechanism starts, the vacuum self-priming pump 412 and the forward and reverse motor 55 start synchronously, and the winding wheel 52 unwinds the connecting pipe 53; when the drive mechanism stops, the vacuum self-priming pump 412 and the forward and reverse motor 55 stop synchronously. After the drive mechanism stops, the unwinding length of the connecting pipe 53 by the winding wheel 52 should be equal to the water replenishment length of the greenhouse plus the distance between the water replenishment endpoint of the greenhouse and the water replenishment starting point in another greenhouse, so as to facilitate moving the device to the next greenhouse and avoid the unwinding length of the connecting pipe 53 being too long or too short.

[0058] In one possible implementation, one end of the connecting pipe 53 is connected to the water tank, and the other end of the connecting pipe 53 is fixedly provided with an adapter. The adapter is provided with an external thread II in the circumferential direction. The external thread II is threadedly connected to one end of the adapter, and the other end of the adapter is threadedly connected to the external thread I. That is, in the process of connecting the connecting pipe 53 to the vacuum self-priming pump 412, the external thread II on the adapter of the connecting pipe 53 is first threadedly connected to the adapter, and then the adapter is threadedly connected to the external thread I on the vacuum self-priming pump 412.

[0059] In one possible implementation, the RGV trolley 3 is provided with a charging port for charging the battery. After charging the battery in the RGV trolley 3 through the charging port, it can be ensured that the RGV trolley 3 has sufficient power when it is working.

[0060] Working principle:

[0061] First, connect the external thread 2 on the adapter of the connecting pipe 53 to the adapter thread. Then, connect the adapter to the external thread 1 on the vacuum self-priming pump 412. Adjust the hydraulic cylinder 410 according to the width of the greenhouse to make the bogie 403 deflect on the bracket 402. Adjust the angle of the bogie 403 to match the width of the greenhouse. Then, set the moving distance and speed of the RGV trolley 3 according to the length of the greenhouse. Synchronously control the forward and reverse motor 55, drive mechanism and vacuum self-priming pump 412 to start through the controller. The vacuum self-priming pump 412 supplies water to each nozzle 407 along the connecting pipe 53 and guide pipe 405. The water flow can be adjusted through the valve body 406. The RGV trolley 3 moves along the track 1. While moving, the vegetable seedlings inside the greenhouse are watered. At this time, the brake is closed, and the forward and reverse motor 55 is also started simultaneously. The forward and reverse motor 55 drives the driven sprocket 54 to rotate through the active sprocket 56 and the chain 57. After the winding wheel 52 rotates, it loosens the connecting pipe 53. When the RGV trolley 3 moves to a fixed distance and stops, the hydraulic cylinder 410 is manually controlled to reset. The two side bogies 403 move towards each other to fold. Then the closed door of the greenhouse on this side and the closed door of the adjacent greenhouse are opened. The personnel push the RGV trolley 3 along the sealed door and track 1 through the handrail 6 to move to the next greenhouse. The above steps are repeated to water the seedlings until the RGV trolley 3 moves to the last greenhouse in the single row and completes the watering work.

[0062] When the next watering operation is needed, the angle of the bogie 403 is adjusted to match the width of the greenhouse. The controller synchronously controls the start of the forward and reverse motor 55, the drive mechanism, and the vacuum self-priming pump 412. At this time, the forward and reverse motor 55 rotates in the opposite direction, the winding wheel 52 winds up the connecting pipe 53, and the drive mechanism drives the RGV trolley 3 to move in the opposite direction along the track 1 and waters the vegetable seedlings through the nozzle 407. After the RGV trolley 3 moves in the opposite direction to a fixed distance and stops, the hydraulic cylinder 410 is manually controlled to reset, and the two bogies 403 move towards each other to fold. Then the closed door of the greenhouse on this side and the closed door of the adjacent greenhouse are opened. Personnel push the RGV trolley 3 along the sealed door and track 1 through the handrail 6 to move to the next greenhouse and repeat the above steps to water the seedlings until the RGV trolley 3 moves to the last greenhouse in the single row and completes the watering operation. This process is repeated to form a cyclical watering operation.

[0063] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
