Description

Technical Field

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

[0002] Vegetable seedling cultivation is the entire process of cultivating vegetable seeds until they grow into seedlings. Especially for vegetables grown in greenhouses, it is necessary to cultivate seeds in batches, bury the seeds in the soil of the seedling planting area, and irrigate them by spraying water through a water spraying device.

[0003] A search revealed Chinese patent CN222340138U, which discloses a water spraying device for a vegetable seedling greenhouse, relating to the field of water spraying technology for vegetable seedling greenhouses. The device includes a movable block, a drive assembly, a swing assembly, and a support frame. The drive assembly includes a drive motor and a second gear. The output shaft of the drive motor is fixedly connected to a first gear via a coupling. A connecting shaft is fixedly connected to the upper end of the second gear, and a disc is fixedly connected to the upper end of the connecting shaft. A stop block is fixedly connected to the upper end of the disc. The swing assembly includes a connecting frame. This invention uses a drive motor to rotate the first gear, which in turn drives the second gear. The rotation of the second gear drives the connecting shaft, which in turn drives the disc and the stop block to rotate around the center of the disc. This causes the stop block to slide inside a groove and causes the connecting frame to swing repeatedly, thereby causing the spray head to swing repeatedly to spray water at different angles. This facilitates operation by staff and provides a degree of automation.

[0004] The vegetable seedling greenhouse water spraying device in the above patent has the following shortcomings: it is difficult to move, can only spray water on vegetable seedlings within a certain angle range, the spraying range is limited, and the limitations of the device may cause some seedlings to not receive enough water, affecting the quality and survival rate of the seedlings. Therefore, it is necessary to design a vegetable seedling greenhouse water spraying device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water spraying device for a vegetable seedling greenhouse includes a fixed frame, inside which is a movable seat. A U-shaped seat is fixedly connected to the bottom of the movable seat, and a connecting seat is rotatably connected to the U-shaped seat. Two round rods are fixedly connected to the bottom of the connecting seat, each round rod being fitted with a sleeve. The sleeves are slidably connected to the round rods. A common mounting frame is fixedly connected to the bottom of the two sleeves, and a nozzle is fixedly connected to the mounting frame. A common I-shaped rod is fixedly connected to the two sleeves, and a round tube is fitted onto the I-shaped rod. The round tube is rotatably connected to the I-shaped rod. A square plate is fixedly connected to the outer wall of the round tube, and a fixed seat is fixedly connected to one side of the square plate. A roller is rotatably connected to the fixed seat, and slide rails are fitted at both ends of the roller, which are slidably connected to the slide rails. The slide rails are fixedly connected to... The fixed frame, by employing a technology that allows the spray nozzles to oscillate back and forth during movement, increases the spraying range. The reciprocating movement, combined with linear motion, further expands the water spraying area, covering a wider region and ensuring more vegetable seedlings are sprayed. This effectively solves the problem mentioned in the background technology: existing equipment is difficult to move, can only spray water on seedlings within a certain angle range, and has a limited spraying range. The limitations of the equipment may result in some seedlings not receiving enough water, affecting seedling quality and survival rate. Therefore, this design ensures that most vegetable seedlings in the seedling area receive water, reducing drought or insufficient water caused by limited spraying range, thereby improving seedling growth quality and health, and enhancing the flexibility of the equipment.

[0009] As a further embodiment of this utility model, two fasteners are fixedly connected to the outer walls on both sides of the top of the fixing frame, and the fasteners are provided with mounting holes.

[0010] As a further embodiment of this utility model, sleeves are fixedly connected to the inner walls of both sides of the top of the connecting seat, and the two sleeves are rotatably connected to the same drive screw. A screw nut is sleeved on the drive screw, and the screw nut is adapted to the drive screw. A motor is fixedly connected to one side of the fixing frame, and the output end of the motor is connected to the drive screw through a coupling.

[0011] As a further embodiment of this utility model, the lead screw nut is fixedly connected to the movable seat, and guide rods are provided at both ends of the movable seat. The movable seat is slidably connected to the guide rods, and the guide rods are fixedly connected to the inner wall of the fixed frame.

[0012] The beneficial effects of this utility model are as follows: By employing a technique that allows the nozzle to oscillate back and forth during movement, the spraying range is increased. The reciprocating motion, combined with linear movement, further expands the spraying area, covering a wider region and ensuring more seedlings are sprayed. This effectively solves the problem raised in the background technology: existing equipment is difficult to move, can only spray seedlings within a certain angle range, and has a limited spraying range. The limitations of the equipment may result in some seedlings not receiving enough water, affecting seedling quality and survival rate. This technology ensures that most seedlings in the seedling area receive water, reducing drought or insufficient water caused by limited spraying range, thereby improving seedling growth quality and health, and enhancing equipment flexibility.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-6 A water spraying device for a vegetable seedling greenhouse includes a fixed frame 1. A movable seat 2 is installed inside the fixed frame 1. A U-shaped seat 3 is fixedly connected to the bottom of the movable seat 2. A connecting seat 4 is rotatably connected to the U-shaped seat 3. Two round rods 5 are fixedly connected to the bottom of the connecting seat 4. Each round rod 5 is fitted with a sleeve 6, which slidably connects to the round rods 5. A common mounting frame 7 is fixedly connected to the bottom of the two sleeves 6. A nozzle 8 is fixedly connected to the mounting frame 7. A common I-shaped rod 9 is fixedly connected to the two sleeves 6. A round tube 10 is fitted onto the I-shaped rod 9, which rotatably connects to the I-shaped rod 9. A square plate 11 is fixedly connected to the outer wall of the round tube 10. A fixed seat 13 is fixedly connected to one side of the square plate 11. A roller 14 is rotatably connected to the fixed seat 13. Slide rails 15 are fitted at both ends of the roller 14, which slidably connect to the slide rails 15. The 15 fixed connection frame 1, by employing a technique that allows the nozzle to swing back and forth during the movement of the nozzle, increases the spraying range. Simultaneously, the nozzle moves linearly, further expanding the water spraying area and covering a wider region, ensuring more vegetable seedlings are sprayed. This effectively solves the problem mentioned in the background technology that existing equipment is difficult to move, can only spray water on vegetable seedlings within a certain angle range, and has a limited spraying range. The limitations of the equipment may cause some seedlings to not receive enough water, affecting seedling quality and survival rate. This design ensures that most vegetable seedlings in the seedling area receive water, reducing drought or insufficient water due to limited spraying range, thereby improving seedling growth quality and health, and enhancing the flexibility of the equipment.

[0017] In this embodiment, a square groove 12 is provided on the square plate 11, and a limiting plate 16 is provided in the square groove 12. The square plate 11 is slidably connected to the limiting plate 16. Through the cooperation of the square groove 12 and the limiting plate 16, the square plate 11 will move along the limiting plate 16 when it moves. When the square plate 11 moves laterally, it is restricted by the limiting plate 16, and the square plate 11 will only move on one plane and will not deviate.

[0018] In this embodiment, a hose 17 is fixedly connected to the input end of the nozzle 8, and the hose 17 is connected to an external water supply device.

[0019] In this embodiment, two fasteners 18 are fixedly connected to the outer walls on both sides of the top of the fixing frame 1. The fasteners 18 have mounting holes, and bolts can be used to pass through the mounting holes on the fasteners 18 to fix the device to the top frame of the vegetable shed.

[0020] In this embodiment, sleeves 19 are fixedly connected to the inner walls of both sides of the top end of the connecting seat 4. The two sleeves 19 are rotatably connected to the same drive screw 20. A screw nut 21 is sleeved on the drive screw 20. The screw nut 21 is adapted to the drive screw 20. A motor 22 is fixedly connected to one side of the fixing frame 1. The output end of the motor 22 and the drive screw 20 are connected by a coupling.

[0021] In this embodiment, the lead screw nut 21 is fixedly connected to the movable seat 2. Guide rods 23 are provided at both ends of the movable seat 2. The movable seat 2 is slidably connected to the guide rods 23. The guide rods 23 are fixedly connected to the inner wall of the fixed frame 1. When the movable seat 2 moves, it will move along the guide rods 23 to ensure the stability of the movable seat 2 when it moves.

[0022] Working Principle: When in use, an external power supply is used. The motor 22 is started by the external controller, and water is supplied to the hose 17 through the external water supply device. Water is injected into the nozzle 8 through the hose 17 and sprayed out through the nozzle 8. The rotation of the output end of the motor 22 causes the drive screw 20 to rotate, which in turn moves the screw nut 21. The screw nut 21 then moves the moving seat 2 along the guide rod 23. The movement of the moving seat 2 moves the U-shaped seat 3, which in turn moves the connecting seat 4. The connecting seat 4 then moves the round rod 5, which in turn moves the sleeve 6. The sleeve 6 then moves the mounting bracket 7, which in turn moves the nozzle 8. The movement of the sleeve 6 also moves the I-shaped rod 9, which in turn moves the round tube 10. The round tube 10 then moves the square plate 11, which in turn moves the fixed seat 13. The fixed seat 13 then moves the roller 14 along the slide rail 15. The roller 14 then moves... During the process, the roller 14 moves back and forth towards the I-shaped rod 9, causing the fixed seat 13 to move back and forth. The fixed seat 13 then moves the square plate 11 along the limiting plate 16. The square plate 11 moves on the same horizontal plane, which in turn moves the round tube 10. The round tube 10 then moves the I-shaped rod 9, which in turn moves the sleeve 6. The sleeve 6 tilts around the connection between the connecting seat 4 and the U-shaped seat 3, causing it to swing back and forth. The sleeve 6 slides on the round rod 5, which in turn causes the round rod 5 to swing back and forth, allowing the connecting seat 4 to rotate back and forth on the U-shaped seat 3. The swinging of the sleeve 6 causes the mounting frame 7 to swing back and forth, which in turn causes the nozzle 8 to swing back and forth during the movement, increasing the spraying range. This causes the output end of the motor 22 to rotate in the opposite direction, returning the moving seat 2 to its initial position. This process is repeated to spray water onto the vegetables.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
