Description
Technical Field
[0001] This utility model relates to the field of irrigation equipment technology, and in particular to a wheat irrigation device with adjustable angle. Background Technology
[0002] In the field of agricultural irrigation, the flexibility and adaptability of irrigation devices are crucial for irrigating crops such as wheat. Existing irrigation devices have a fixed irrigation height. However, in actual use, during the early stages of wheat growth, when the wheat plants are relatively short, if the irrigation height is too high, the irrigation water may not be able to accurately reach the wheat roots. In the later stages of growth, when the plants are taller, the fixed irrigation height may not be able to cover the upper part of the wheat plants. At the same time, the irrigation angle of existing irrigation devices can usually only perform circumferential uniform spraying, which is difficult to meet the needs of regional directional spraying irrigation. This can easily lead to over-irrigation in some areas and under-irrigation in others. This makes it difficult for existing irrigation devices to quickly and flexibly adjust the spraying angle according to the actual growth of wheat, resulting in a significant reduction in irrigation effectiveness.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 - Figure 3This utility model provides an embodiment of an angle-adjustable wheat irrigation device, comprising a water supply pipe 1, a guide pipe 2, a guide groove 3, a connecting pipe 4, and a guide strip 5. An irrigation component 6 is provided on the top surface of the connecting pipe 4. The irrigation component 6 includes a fixed pipe 61 threadedly connected to the top of the connecting pipe 4. A conical member 62 is rotatably connected inside the fixed pipe 61. An inlet 63 is uniformly provided through the bottom surface of the conical member 62, and a first outlet 64 is uniformly provided through the side wall surface of the conical member 62. Positioning grooves 65 are uniformly provided on the side wall surface of the conical member 62. An adjusting cover 66 is rotatably connected to the top surface of the conical member 62. An installation groove 67 is provided inside the adjusting cover 66, and a compression spring 68 is provided inside the adjusting cover 66, with the compression spring 68 located near the positioning groove 65. One end of the tube is fixedly connected to a positioning steel ball 69. A second water outlet 60 is opened on the side wall surface of the adjusting cover 66. A switching component 610 is installed inside the fixed tube 61. The guide tube 2 is evenly fixedly connected to the top surface of the water supply tube 1. The connecting tubes 4 are all slidably connected to the inside of the guide groove 3 through the guide strip 5. The connecting tube 4 is slidably connected to the inside of the guide tube 2. The top of the conical part 62 is open. The second water outlet 60 and the first water outlet 64 are on the same horizontal line. The end of the compression spring 68 away from the positioning steel ball 69 is fixedly connected to the inner wall surface of the mounting groove 67. The positioning steel ball 69 abuts against the inside of one of the positioning grooves 65. When the conical part 62 is inside the fixed tube 61, it can form a sealing structure with the inner wall of the fixed tube 61. The water supply tube 1 is connected to the outside. The water pump connection can be synchronized with a water pressure regulator. Both the water pump and the water pressure regulator are existing technologies and will not be elaborated further. After the water supply pipe 1 is connected to the external water pump, the water pressure can be adjusted using the water pressure regulator. Since the connecting pipes 4 are all slidably connected inside the guide groove 3 via guide strips 5, when irrigation water reaches the water supply pipe 1 through the water pump, it passes through the guide pipe 2 and reaches the inside of the connecting pipe 4. During this process, the water pressure of the irrigation water pushes the connecting pipe 4 to slide upward inside the guide pipe 2. By adjusting the water pressure using the water pressure regulator, the height at which the connecting pipe 4 slides upward inside the guide pipe 2 can be controlled, thereby controlling the height of vertical irrigation. For example, in the early stages of wheat growth, when the plants are relatively short, the irrigation height can be appropriately lowered to allow for more precise irrigation. This irrigation water is used for the wheat roots. Later in the wheat's growth, when the plants are taller, the irrigation height can be increased to ensure the water covers the upper part of the wheat plants, meeting the irrigation needs of wheat at different growth stages and improving irrigation efficiency and effectiveness. The irrigation water then reaches the fixed pipe 61. In the initial state, the water enters the conical part 62 through the inlet 63 and is then sprayed out through the first outlet 64 and the second outlet 60, thus achieving spray irrigation. Since there is only one second outlet 60, it can only achieve directional spray irrigation of the wheat. When the spray angle needs to be adjusted, the adjusting cover 66 can be rotated. The rotation of the adjusting cover 66 causes the second outlet 60 to rotate in a circular motion.The positioning steel ball 69 moves, pressing against the edge of the positioning groove 65, thus compressing the spring 68. When the adjusting cover 66 rotates to the appropriate position, the second outlet 60 and the first outlet 64 are on the same horizontal line, thereby adjusting the spraying angle. This is suitable for regional directional spraying irrigation.
[0022] Please see Figure 1 - Figure 3 The switching component 610 includes a mounting bracket 611 fixedly connected between the inner wall surfaces of the fixed tube 61. A connecting rod 612 is movably connected inside the mounting bracket 611. A limit plate 613 is rotatably connected to the bottom surface of the connecting rod 612. A tension spring 614 is fixedly connected between the opposing surfaces of the limit plate 613 and the mounting bracket 611. A guide groove 615 is evenly distributed on the bottom surface of the conical member 62. A lever 616 is fixedly connected to the side wall surface of the conical member 62. An L-shaped limit block 617 is fixedly connected to the bottom surface of each lever 616. A connecting groove 618 is formed on the top surface of the fixed tube 61. The top surface of 61 is provided with a snap-fit groove 619. The top surface of the connecting rod 612 is fixedly connected to the bottom surface of the conical part 62. The guide grooves 615 are all arc-shaped and are circumferentially formed on the bottom surface of the conical part 62. The L-shaped limiting block 617 is movably connected inside the connecting groove 618. The connecting groove 618 and the snap-fit groove 619 are interconnected. When it is necessary to spray irrigation for wheat, the lever 616 can be moved in the opposite direction of the arc of the guide groove 615. The lever 616 drives the conical part 62 to rotate, causing the L-shaped limiting block 617 to disengage from the inside of the snap-fit groove 619. At this time, the tension spring 614 contracts. Since the mounting bracket 611 is fixedly connected to the inner wall surface of the fixed pipe 61, and the connecting rod 612 is movably connected to the mounting bracket 611, the tension spring 614 contracts, causing the limiting plate 613 to move upward. At the same time, the connecting rod 612 pushes the conical piece 62 upward, thereby causing the L-shaped limiting block 617 to slide upward out of the interior of the connecting groove 618. At this time, under the impact of irrigation water, most of the irrigation water will spray out through the outlet formed by the guide channel 615 and the top edge of the fixed pipe 61. Since the guide channel 615 is arc-shaped and circumferentially opened on the bottom surface of the conical piece 62, the irrigation water... Under the impact, the conical part 62 will rotate, causing the guide channel 615 to rotate as well. This allows irrigation water to be sprayed out through the guide channel 615, achieving comprehensive and uniform spray irrigation for wheat. When directional spray irrigation is needed, simply align the L-shaped limiting block 617 with the connecting groove 618 and press down the lever 616. At this time, the tension spring 614 will stretch, causing the L-shaped limiting block 617 to slide into the interior of the connecting groove 618. Then, move the lever 616 in the arc direction of the guide channel 615. The lever 616 will drive the conical part 62 to rotate, causing the L-shaped limiting block 617 to re-engage into the locking groove 619.
[0023] Working principle: In use, the water supply pipe 1 is connected to an external water pump and equipped with a water pressure regulator. After the irrigation water reaches the water supply pipe 1 via the pump, it flows through the guide pipe 2 to the connecting pipe 4. Since the connecting pipe 4 is slidably connected to the guide groove 3 via the guide bar 5, the water pressure of the irrigation water pushes the connecting pipe 4 to slide upward within the guide pipe 2. The sliding height of the connecting pipe 4 can be controlled by adjusting the water pressure through the water pressure regulator, thereby controlling the vertical irrigation height. After the irrigation water reaches the inside of the fixed pipe 61, in the initial state, the water enters the conical part 62 through the inlet 63. The water is then sprayed through the first outlet 64 and the second outlet 60 to achieve directional spray irrigation. When the spray angle needs to be adjusted, the adjusting cover 66 is rotated. The adjusting cover 66 drives the second outlet 60 to rotate circumferentially, and at the same time, it drives the positioning steel ball 69 to move. The positioning steel ball 69 presses against the edge of the positioning groove 65, which compresses the compression spring 68. The positioning steel ball 69 and the positioning groove 65 serve to fix the adjusting cover 66. After rotating to the appropriate position, the positioning steel ball 69 will be locked into the corresponding positioning groove 65. Because the second outlet 60 and the first outlet 64 are in the same water... The guide channel 615 is aligned horizontally, allowing for adjustment of the spray irrigation angle. When full spray irrigation is required, the guide lever 616 is moved in the opposite direction of the arc of the guide channel 615. The lever 616 drives the conical part 62 to rotate, causing the L-shaped limiting block 617 to disengage from the locking groove 619. At this time, the tension spring 614 contracts, causing the limiting plate 613 to move upward. The connecting rod 612 pushes the conical part 62 upward, causing the L-shaped limiting block 617 to slide out of the connecting groove 618. Under the impact of irrigation water, most of the water is sprayed out through the outlet formed by the guide channel 615 and the top edge of the fixed pipe 61. Because the guide channel 615 is arc-shaped and circumferentially located at the bottom of the conical part 62, the conical part 62 rotates, causing the guide channel 615 to rotate and spray water, achieving comprehensive and uniform spray irrigation. When it is necessary to restore directional spray irrigation, align the L-shaped limiting block 617 with the connecting groove 618, press down the lever 616, stretch the spring 614, and let the L-shaped limiting block 617 slide into the connecting groove 618. Then, move the lever 616 in the arc direction of the guide channel 615 to drive the conical part 62 to rotate, so that the L-shaped limiting block 617 can be re-engaged into the locking groove 619.
