[0021] 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.
[0022] Example 1:
[0023] Please see Figures 1 to 4This utility model provides a technical solution: a channel structure for farmland irrigation, including an irrigation channel 1 and a base 2. The irrigation channel 1 can be made of corrosion-resistant metal, plastic, or concrete. A retrieval device 3 is provided on the top of the base 2. Limiting grooves 4 are provided on both sides of the base 2. Limiting rods 5 are slidably connected inside the limiting grooves 4. One end of the limiting rod 5 is fixedly connected to a limiting plate 6. A drive wheel 7 is installed inside the limiting plate 6. A telescopic spring 8 is fixedly connected between the other end of the limiting rod 5 and the limiting groove 4. Through the deformation of the telescopic spring 8, the two limiting plates 6 can be stretched to a corresponding width according to the width of the irrigation channel 1, thus fixing the two limiting plates 6 onto the irrigation channel 1, in conjunction with the drive wheel 7. The system facilitates the movement of the base 2 and the retrieval device 3. Positioning plates 25 are installed on both sides of the base 2, corresponding to the top of the limiting rod 5. Bolts 26 are threaded into the internal parts of the positioning plates 25. A positioning hole 27 is provided at the top of the limiting rod 5, and one end of the bolt 26 is inserted into the positioning hole 27 to fix the position of the limiting rod 5. Guide grooves 20 are provided on both sides of the irrigation channel 1, and a groove 21 is provided on the inner side of the limiting plate 6. An auxiliary wheel 22 is rotatably connected inside the groove 21. The auxiliary wheel 22 fits into the guide groove 20, assisting the limiting plate 6 in moving while cooperating with the guide groove 20 to limit the movement of the limiting plate 6, preventing the device from easily detaching from the irrigation channel 1. The retrieval device 3... An internal groove 9 is provided, and a slider 10 is slidably connected inside the groove 9. A support shaft 11 is rotatably connected to one side of the slider 10. A bracket 12 is fixedly connected to one end of the support shaft 11, and a filter screen frame 13 is fixedly connected to the bottom of the bracket 12. The filter screen frame 13 has a U-shaped structure, which filters impurities in the water while allowing impurities to pass through without obstruction at both ends. A support ring 14 is sleeved on the outside of the support shaft 11. A support plate 24 is installed on one side of the retrieval device 3. An electric push rod 15 is installed on the bottom plate of the support plate 24. The output end of the electric push rod 15 is fixedly connected to the support ring 14. Through the sleeve of the support ring 14 and the support shaft 11, the support shaft 11 and the filter screen frame 13 are supported. The support ring 14 does not obstruct the rotation of the support shaft 11. The electric push rod 15 can drive the support ring 14 and the support shaft 11 to rise and fall, adjusting the height of the filter screen frame 13 so that the filter screen frame 13 can scoop up debris from the water in the irrigation channel 1. A gear 16 is installed on the outside of the support shaft 11 and on one side of the support ring 14. A rack 17 is installed on one side of the gear 16 in the scooping device 3. The rack 17 meshes with the gear 16, so that the gear 16 meshes with the rack 17 as the support shaft 11 and the filter screen frame 13 rise and fall. The gear 16 and the support shaft 11 rotate accordingly, causing the filter screen frame 13 to tilt, facilitating the discharge of debris from the filter screen frame 13 and cleaning the irrigation channel 1, which helps to prevent blockage of the irrigation channel 1.
[0024] Example 2:
[0025] Please see Figure 1 , Figure 2 , Figure 4 The base 2 houses a self-locking motor 18. A ventilation opening is located on the back of the base 2, next to the self-locking motor 18. The output of the self-locking motor 18 is connected to the center of the retrieval device 3, driving it to rotate. This facilitates adjustment of the direction of the filter frame 13, allowing it to be moved away from the irrigation channel 1. A brush plate 23 is installed on one side of the limiting plate 6. The bristles of the brush plate 23 are in contact with the top of the irrigation channel 1, allowing it to clean debris from the irrigation channel 1 as the base 2 moves, thus avoiding obstruction of the movement of the base 2 and the retrieval device 3. A waterproof switch 19 is installed on the surface of the retrieval device 3.
[0026] The instruction manual is required. The waterproof switch 19 is used to control the electric linear actuator and the self-locking motor. The electric linear actuator and the self-locking motor are powered by an external mobile power supply.
[0027] In summary, this channel structure for farmland irrigation operates as follows: During use, the limiting rods 5 on both sides of the sliding base 2 open the limiting plates 6 at one end of the two limiting rods 5. After releasing the limiting rods 5, the extension springs 8 at the other end of the limiting rods 5 reset the limiting rods 5, causing the two limiting plates 6 to press against and compress the irrigation channel 1. Simultaneously, the bolts 26 connected to the internal threads of the positioning plates 25 on both sides of the sliding base 2 are rotated, inserting one end into the positioning hole 27 at the top of the limiting rod 5. The drive wheel 7 inside the limiting plate 6 then presses against the irrigation channel 1. At the same time, the auxiliary wheel 22 in the groove 21 inside the limiting plate 6 enters the guide grooves 20 on both sides of the irrigation channel 1. The rotation of the drive wheel 7 causes the base 2 and the retrieval device 3 to move on the irrigation channel 1. Simultaneously, the bracket 12 at one end of the support shaft 11 on one side of the retrieval device 3 drives the filter frame 13 to move against the irrigation channel 1. After the debris in the inner water is filtered, the rack 17 is connected to the support ring 14 on the outside of the support shaft 11 through the output end. Under the action of the slider 10 sliding in the inner groove 9 of the retrieval device 3 and the rotational connection with the support shaft 11, the support shaft 11 is raised. After the debris is picked up, the self-locking motor 18 drives the retrieval device 3 to rotate, adjusting the direction of the filter screen frame 13 so that one end of the filter screen frame 13 is moved away from the irrigation channel 1. At the same time, since the gear 16 on the outside of the support shaft 11 meshes with the rack 17 on the retrieval device 3, the gear 16 contacts the rack 17 during the upward movement and drives the support shaft 11 to rotate. The filter screen frame 13 tilts accordingly. At this time, the lower end of the filter screen frame 13 is located outside the irrigation channel 1. After the debris is discharged, the filter screen frame 13 is reset and re-enters the inner water of the irrigation channel 1.
[0028] 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.
