Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to an automatic irrigation device. Background Technology

[0002] Automatic irrigation devices are widely used in modern agriculture. They replace traditional manual irrigation with automation, effectively improving water resource utilization efficiency and management convenience. With the development of large-scale and intelligent agriculture, the requirements for the functionality and reliability of irrigation devices are constantly increasing, prompting continuous technological innovation and optimization in this field.

[0003] Currently, most common automatic irrigation devices on the market adopt a fixed structure design, with irrigation components installed at a fixed height. They rely on water pumps and pipeline systems to deliver water and complete irrigation operations through nozzles or drip irrigation tapes. In terms of heat dissipation and protection, some devices only have simple grid-like heat dissipation holes and are not equipped with effective insect and dust prevention structures, or they use non-removable filters, making it difficult to perform regular cleaning and maintenance.

[0004] Clearly, existing automatic irrigation devices have significant shortcomings. Because the height of the irrigation components is not adjustable, when crops grow to a higher stage, the fixed-height spraying equipment cannot cover all plants, resulting in uneven irrigation and insufficient water in some areas, which affects crop growth. At the same time, the heat dissipation holes of the equipment lack effective protection, and insects and debris can easily enter the equipment during operation, causing poor heat dissipation or even mechanical failure. This not only reduces the stability of equipment operation, but also significantly increases the cost of use and maintenance workload due to frequent repairs and replacements of parts. Therefore, an automatic irrigation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic irrigation device, which aims to improve the problem of insufficient irrigation range after plants grow tall in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic irrigation device includes a fixed column, a lifting column slidably connected inside the fixed column, a spraying component at the top of the fixed column, a fixing component at the bottom of the fixed column, and an adjusting component on the side of the fixed column.

[0008] The adjustment assembly includes a motor box, which is fixedly connected to the outer wall of the fixed column. A connecting rod is rotatably connected to the inner wall of the motor box. A gear is fixedly connected to the center of the outer wall of the connecting rod. A rack is fixedly connected to the outer wall of the lifting column along the vertical direction of the lifting column. The gear meshes with the rack. A power assembly is provided on one side inside the motor box. The power assembly is used to drive the gear to rotate.

[0009] As a further description of the above technical solution:

[0010] The power assembly includes a drive motor, the bottom of which is fixedly connected to the inner wall of the motor housing. A worm gear is fixedly connected to the output end of the drive motor, and the other end of the worm gear is rotatably connected to the inner wall of the motor housing. A worm wheel is provided above the worm gear, and the worm gear meshes with the worm wheel. The center of the worm wheel is fixedly connected to the outer wall of the connecting rod, and the worm wheel is located on one side of the gear. Multiple heat dissipation holes are provided on both sides of the outer wall of the motor housing, and the heat dissipation holes are distributed in a straight line.

[0011] As a further description of the above technical solution:

[0012] The spraying assembly includes a rotating base, and multiple sprayers are fixedly connected to the outer wall of the rotating base. The multiple sprayers are evenly distributed in a circumferential shape on the outer wall of the rotating base.

[0013] As a further description of the above technical solution:

[0014] The spraying assembly includes a rotating base, and multiple sprayers are fixedly connected to the outer wall of the rotating base. The multiple sprayers are evenly distributed in a circumferential shape on the outer wall of the rotating base.

[0015] As a further description of the above technical solution:

[0016] A base is provided below the rotating seat, the bottom of the base is fixedly connected to the top of the lifting column, and the bottom of the rotating seat is rotatably connected to the top of the base.

[0017] As a further description of the above technical solution:

[0018] A fixing plate is provided on the outer side of the heat dissipation holes on both sides. The side wall of the fixing plate is fixedly connected to the outer wall of the motor box. An insect-proof net is slidably connected inside the fixing plate, and a handle is fixedly connected to the top of the insect-proof net.

[0019] As a further description of the above technical solution:

[0020] Multiple limiting plates are provided on both sides of the interior of the fixed plate, and a limiting ball is fixedly connected to one side of the outer wall of each of the multiple limiting plates. The outer walls of the limiting plates and the limiting balls are slidably connected inside the fixed plate.

[0021] As a further description of the above technical solution:

[0022] Each of the limiting plates has a limiting spring on the other side of its outer wall. One end of the limiting spring is fixedly connected to the inside of the fixed plate, and the other end of the limiting spring is fixedly connected to the side wall of the limiting plate.

This solves the problem of insufficient irrigation range after the plants grow taller and improves the effectiveness and adaptability of irrigation.

[0025] 2. In this utility model, the operator can pull the insect-proof net out of the fixed plate for cleaning by using the handle. When it is reinserted, the outer wall of the insect-proof net squeezes the limiting ball, which compresses the limiting spring.

This achieves the effect of quickly disassembling the insect-proof net, solves the problem of airflow obstruction caused by the insect-proof net being blocked, and causes the equipment to overheat. It also improves the stability of equipment operation and service life. Attached Figure Description

[0033] 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.

[0034] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automatic irrigation device, including a fixed column 1, which serves as a support component. The fixed column 1 is made of seamless steel pipe of Q235B material and has a hot-dip galvanized surface, providing good structural strength and corrosion resistance. A spraying assembly is installed at the top, a fixed assembly is located at the bottom, and an adjustment assembly is configured on the side. A lifting column 2, also made of Q235B seamless steel pipe and hot-dip galvanized, is slidably connected inside the fixed column 1. Its outer wall forms a clearance fit with the sliding cavity inside the fixed column 1, ensuring that the lifting column 2 can slide smoothly within the fixed column 1. The lifting column 2 is used to adjust the height of the spraying assembly to meet the irrigation needs of plants at different growth stages. A through hole is provided inside the lifting column 2, and a connecting water pipe is installed within the through hole. This water pipe is used to connect to an external water supply pipe to provide a water source for the spraying assembly. The fixed column 1 supports the lifting column 2, the spraying assembly, and other components, providing a stable installation foundation for the entire irrigation device.

[0035] The spraying assembly installed on the top of the fixed column 1 is responsible for spraying irrigation water. The spraying assembly includes a base 5, which serves as the mounting carrier for the spraying assembly. The bottom of the base 5 is fixedly connected to the top of the lifting column 2 by bolts, supporting the rotating seat 6 and the sprayer 7. The rotating seat 6 is made of aluminum alloy, and its outer wall is fixedly connected by bolts to multiple sprayers 7 arranged in a circular pattern. The sprayer 7 is made of ABS engineering plastic injection molding and has an adjustable nozzle inside. The nozzle is made of 304 stainless steel and can adjust the spraying angle and range according to irrigation needs, so as to evenly spray pressurized water onto the surrounding plants. The bottom of the rotating seat 6 is rotatably connected to the top of the base 5 through a bearing, and can rotate under the drive of the base 5, driving the sprayer 7 to rotate and expand the irrigation coverage area. The base 5, the rotating seat 6, and the sprayer 7 are all existing technologies and will not be described in detail in this article.

[0036] The fixing component at the bottom of the fixing column 1 is used to securely install the irrigation device on the ground. The fixing component is mainly composed of the base plate 3, which is made of Q235B steel plate. The top center of the base plate is connected to the bottom of the fixing column 1 by welding. Multiple fixing holes 4 are drilled inside the base plate 3 in a circular pattern. The fixing holes 4 are used to insert ground nails to fix the base plate 3 to the ground, thereby ensuring the stability of the entire irrigation device.

[0037] An adjustment assembly located on the side of the fixed column 1 is used to adjust the height of the lifting column 2. The adjustment assembly has a motor box 8 as its outer shell, which is made of 304 stainless steel plate bent and welded. The side wall is fixedly connected to the outer wall of the fixed column 1 by bolts. A drive motor 10 is fixedly connected to the bottom of the inner wall of the motor box 8. The drive motor 10 is used to provide power to the adjustment assembly. The drive motor 10 is existing technology and will not be described in detail here. The motor box 8 is used to house and protect the drive motor 10 and other components. The output end of the drive motor 10 is fixedly connected to the worm gear 11 through a coupling. The worm gear 11 meshes with the worm wheel 12 to power the drive motor 10. The rotational motion is transmitted to the worm gear 12, which is fixed to the connecting rod 14 by a key. The connecting rod 14 is rotatably connected to the inner wall of the motor box 8 by a bearing, which supports the worm gear 12 and the gear 13 and transmits the rotational motion. The gear 13 is fixed to the side of the worm gear 12 by a key. The gear 13 is used to convert the rotational motion of the worm gear 12 into the linear motion of the rack 15. The tooth pitch of the rack 15 on the side of the gear 13 matches the module of the gear 13. It is fixed inside the lifting column 2 by welding and meshes with the gear 13. It is used to convert the rotational motion of the gear 13 into the linear displacement of the lifting column 2, so as to realize the height adjustment of the lifting column 2.

[0038] Reference Figures 3-5The motor box 8 serves as a protective shell for components such as the drive motor 10 in the adjustment assembly. Multiple heat dissipation holes 9 are arranged in an array on both sides of its outer wall through a drilling process. The heat dissipation holes 9 adopt a strip-shaped design. This layout maximizes the heat dissipation area while ensuring the structural strength of the motor box 8. The heat dissipation holes 9 are mainly used to accelerate the air circulation inside the motor box 8, dissipating the heat generated by components such as the drive motor 10 in a timely manner, and preventing the components from overheating due to heat accumulation, which could affect performance or shorten service life. Fixing plates 16 are provided on the outer sides of the heat dissipation holes 9 on both sides. The fixing plates 16 are made of 304 stainless steel sheet, bent and formed, and fixedly connected to the outer wall of the motor box 8 by welding. Rectangular guide grooves are machined inside the fixing plates 16 to provide a sliding track for the insect net 17, while also protecting the edges of the heat dissipation holes 9 and preventing damage from external impacts. The insect net 17, which is slidably connected inside the fixing plates 16, is woven from 304 stainless steel wire. It effectively blocks insects, leaves, dust, and other debris from entering the motor box 8, while ensuring smooth airflow for heat dissipation. A handle 18 is fixedly connected to the top of the insect net 17 by welding. The insect-proof net 17 is treated with an anti-slip coating to facilitate the pulling and retraction of the net by workers. Multiple limiting plates 20 are installed on both sides of the inner side of the fixing plate 16. A limiting ball 21, made of bearing steel, is welded to one side of the outer wall of the limiting plate 20 to secure it in place. Both the outer walls of the limiting plates 20 and the limiting balls 21 slide against the guide grooves inside the fixing plate 16, ensuring the stability of the net. The limiting ball 21 can slide smoothly within the fixed plate 16. A limiting spring 19 is provided on the other side of the outer wall of the multiple limiting plates 20. The limiting spring 19 is made of spring steel. One end of the limiting spring 19 is welded to a spring seat preset inside the fixed plate 16, and the other end is welded to the side wall of the limiting plate 20. It is used to provide a reset force for the limiting plate 20 and the limiting ball 21, ensuring that the limiting ball 21 can always maintain the engagement state with the groove of the insect net 17, and ensuring the stability of the insect net 17 during operation.

[0039] Working principle: When using this automatic irrigation device, the staff first fixes the device to the ground by using ground nails and fixing holes 4. Then, the water supply pipe is connected to the water pipe in the through hole of the lifting column 2 inside the device. The water pump inside the device pressurizes the water and sprays it out through the sprayer 7. At the same time, the micro motor inside the base 5 drives the rotating seat 6 to rotate. The rotation of the rotating seat 6 also causes multiple sprayers 7 to rotate, spraying and irrigating the surrounding plants.

[0040] As the plant grows taller, the drive motor 10 inside the motor box 8 drives the worm gear 11 to rotate. The rotation of the worm gear 11 drives the worm wheel 12 to rotate through the meshing relationship. The rotation of the worm wheel 12 drives the gear 13 to rotate synchronously through the connecting rod 14. The rotation of the gear 13 drives the rack 15 to move upward through the meshing relationship, which in turn drives the lifting column 2 to move upward as a whole. The displacement of the lifting column 2 causes the rotating seat 6 and the sprayer 7 to move upward as well, thereby achieving the effect of adjusting the height of the device.

[0041] During normal operation, the equipment dissipates heat through the heat dissipation holes 9 on both sides of the motor box 8. Insects and debris in the environment are attracted and stuck to the surface of the insect-proof net 17. The staff can pull the insect-proof net 17 out of the fixed plate 16 through the handle 18 for cleaning. After cleaning, the staff inserts the insect-proof net 17 back into the fixed plate 16. At this time, the outer wall of the insect-proof net 17 will squeeze the multiple limiting balls 21 on both sides of the fixed plate 16, causing the limiting balls 21 to drive the limiting plate 20 back into the fixed plate 16 and squeeze the limiting spring 19. When the insect-proof net 17 is fully inserted, the limiting spring 19 pushes the limiting plate 20 and the limiting balls 21 back to their original positions. The limiting balls 21 are locked into the grooves on the side wall of the insect-proof net 17, completing the limiting of the fixed plate 16, thus achieving the effect of quick installation and removal of the insect-proof net 17.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
