Description

Technical Field

[0001] This invention belongs to the field of agricultural irrigation equipment technology, and in particular relates to a buried agricultural sprinkler irrigation device. Background Technology

[0002] Agricultural irrigation refers to agricultural techniques that use artificial means to deliver water to farmland, orchards, vegetable gardens, and other planting areas to supplement the water needed for crop growth.

[0003] Existing corn irrigation equipment mainly includes fixed above-ground sprinkler poles, buried pop-up sprinklers, and some semi-buried sprinkler systems. These systems are primarily used in cornfields, so an overall height of over 2.5 meters is required to meet irrigation needs. However, practical applications present several problems. Traditional buried sprinklers are mostly short-stroke pop-up structures, low in height and easily obstructed by crops, making it difficult to meet the spraying height and coverage requirements of tall corn stalks. Some liftable sprinkler systems require motors, electrical control systems, or manual operation, resulting in complex wiring, high failure rates, and unsuitability for long-term use in large areas of farmland. Erection and extension mechanisms are often independent, leading to asynchronous movements, complex structures, and a tendency to jam or misalignment over time. Above-ground sprinkler systems are easily damaged by collisions during agricultural machinery operations, resulting in high maintenance costs and disrupting agricultural production continuity. Therefore, we provide a buried agricultural sprinkler system to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a buried agricultural sprinkler irrigation device. This device relies on full water pressure to drive the erection, multi-stage extension and retraction of the sprinkler components, and to perform irrigation operations without the need for electricity or manual operation.

It also addresses the issues of existing agricultural sprinkler irrigation equipment, which mainly consists of above-ground fixed sprinkler poles, buried pop-up sprinklers, and some semi-buried sprinkler irrigation devices. Existing traditional buried sprinklers are mostly short-stroke pop-up structures, low in height, easily obstructed by crops, and unable to meet the spraying height and coverage requirements of orchards and tall crops. Some liftable sprinkler irrigation devices require motors, electrical control systems, or manual operation, resulting in complex wiring, high failure rates, and unsuitability for long-term use in large areas of farmland.

The positioning component fixes the sprinkler assembly through a mechanical locking structure. The entire device has no complex circuits or motor components, greatly reducing the failure rate. It is suitable for long-term continuous use in large areas of farmland. The buried installation mode can avoid collision damage during agricultural machinery tillage and harvesting, reducing equipment maintenance and replacement costs. The nozzle achieves 360° rotation under the reaction force of the water flow impacting the guide vanes, thereby improving the irrigation range and irrigation effect.

[0017] 3. After the sprinkler assembly completes its erection and multi-stage extension, the wedge-shaped block of the positioning assembly slides along the groove to the designated position. Under the action of the return spring, the locking rod automatically inserts into the locking hole to form a firm mechanical lock. This design can effectively counteract water pressure impact and field disturbance, prevent the sprinkler assembly from shaking or shifting, and ensure that the water pressure from the nozzle is stable and uniform, allowing crops to receive water more evenly, improving the overall irrigation quality, and reducing differences in crop growth caused by local over-irrigation or under-irrigation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1-12The present invention provides the following technical solution: a buried agricultural sprinkler irrigation device, comprising a shell assembly 1, an adjustment assembly 2 disposed on one side of the shell assembly 1, a power assembly 3 disposed inside the shell assembly 1, a sprinkler irrigation assembly 4 disposed on the power assembly 3, and a positioning assembly 5 disposed inside the shell assembly 1; the adjustment assembly 2 is used to adjust the water inflow, thereby adjusting the water pressure; the power assembly 3 uses water pressure to unfold the sprinkler irrigation assembly 4 to achieve sprinkler irrigation; the sprinkler irrigation assembly 4 is unfolded using water pressure; the positioning assembly 5 locks the unfolded sprinkler irrigation assembly 4 to ensure its stability during sprinkler irrigation; the shell assembly 1 includes a buried box 101, the top of the buried box 101 is hinged to a sealing cover plate 102 connected by a hinge spring to achieve automatic closure of the sealing cover plate; a first sliding groove 103 is opened in the bottom of the buried box 101, a second sliding groove 104 is opened in the bottom of the buried box 101, and horizontal plates 105 are fixedly connected to the two inner sides of the buried box 101, and an arc-shaped support plate 106 is fixedly connected between the two horizontal plates 105.

[0023] Adjustment component 2 includes an L-shaped plate 201 fixedly connected to an outer side of the underground box 101. A water inlet pipe 202 is fixedly connected through one side of the L-shaped plate 201. A disc 203 is fixedly connected to one end of the water inlet pipe 202. A hexagonal slot 204 is formed through the center of the disc 203. Six guide grooves 205 arranged in a circular array are formed on one side of the disc 203. The six guide grooves 205 form a hexagon. A sliding rod is slidably connected to the inner wall of the guide grooves 205. An adjustment plate 206 is fixedly connected to the end of the sliding rod. Adjacent adjustment plates 206 slide against each other. A connecting post 207 is fixedly connected to one side of the adjustment plate 206. An annular groove 208 is formed on the outer wall of the disc 203. The inner wall of the annular groove 208 is provided with a locking groove 209; the outer wall of the disc 203 is rotatably fitted with an annular cover 210, and the inner wall of the annular cover 210 is fixedly connected with an annular protrusion that slides with the annular groove 208. The outer wall of the annular groove 208 is evenly provided with a plurality of insertion holes 211. A pin 212 is inserted between the locking groove 209 and the insertion holes 211. A handle 213 is fixedly connected to the outer wall of the annular cover 210. A keyway plate 214 that is inclined and slides with the corresponding connecting post 207 is fixedly connected to the inner wall of the annular cover 210. An annular plate 215 that is adapted to the hexagonal slot 204 is fixedly connected between the six keyway plates 214. An extension tube 216 is connected to the end of the annular plate 215.

[0024] The operation process of this embodiment is as follows: After placing the device in the pre-dug pit, the protective cover that is compatible with the adjustment component 2 is then placed on the adjustment component 2 to prevent soil from burying it and hindering subsequent operation or adjustment. The underground box 101 in the shell component 1 provides an underground installation foundation for the entire device. The sealing cover 102 can protect the internal components and prevent soil and debris from entering. The first sliding groove 103 and the second sliding groove 104 at the bottom of the inner part provide guidance for the subsequent movement of the power component 3. The horizontal plate 105 and the arc-shaped support plate 106 play a supporting and limiting role. When the adjustment component 2 is working, first turn the handle 213 to drive the annular cover 21. With 0 rotation, the keyway plate 214 on the inner wall of the annular cover 210 will push the connecting column 207 to move. The connecting column 207 will drive the adjusting plate 206 to slide along the guide groove 205. The sliding cooperation of adjacent adjusting plates 206 can change the cross-sectional area of ​​the water inlet channel, thereby adjusting the water inlet volume and water pressure. After adjustment, the pin 212 is inserted into the locking groove 209 and the corresponding insertion hole 211 to lock the position of the annular cover 210 and ensure stable water pressure. This purely mechanical adjustment method does not require electric drive, has a low failure rate, and is suitable for use in large-area farmland. The extension pipe 216 and the connecting pipe 303 of the power component 3 rotate to ensure stable water flow without affecting the operation of the adjusting component 2.

[0025] Example 2, please refer to Figure 1-12 This second embodiment improves upon the first embodiment as follows: the power assembly 3 includes a pad 301 fixedly connected to the bottom of the housing; a rectangular tube 302 is fixedly connected to the inner wall of the pad 301; a connecting tube 303 is rotatably connected to one end of the rectangular tube 302; the connecting tube 303 rotatably engages with the extension tube 216; a movable tube 304 is slidably connected to the inner wall of the rectangular tube 302; a first mesh plate 305 is fixedly connected to the inner wall of the rectangular tube 302; a second mesh plate 306 is fixedly connected to one end of the movable tube 304; a first spring 307 is fixedly connected between the first mesh plate 305 and the second mesh plate 306; and a first spring 307 is fixedly connected to the top of the movable tube 304. The device includes a toothed plate 308, a guide plate 309 that slides inside the housing and is fixedly connected to the bottom of the moving tube 304, the guide plate 309 slides with the first sliding groove 103, a water outlet pipe 310 connected to the other end of the moving tube 304, a flexible hose 311 connected to the end of the water outlet pipe 310, a first pressure valve on the outer wall of the water outlet pipe 310, and a rotating shaft 312 rotatably connected between the two opposite sides of the housing. A spur gear 313 that meshes with the toothed plate 308 is fixedly connected to the outer wall of the rotating shaft 312, and ear plates 314 are symmetrically fixedly connected to the outer wall of the rotating shaft 312. A mounting plate 315 is fixedly connected between the two ear plates 314.

[0026] The sprinkler assembly 4 includes a first sprinkler pipe 401 fixedly inserted into the mounting plate 315, the first sprinkler pipe 401 being connected to a hose 311, a second sprinkler pipe 402 slidably connected to the inner wall of the first sprinkler pipe 401, a first pipe body 403 connected to the bottom end of the second sprinkler pipe 402, a second pressure valve 404 provided on the outer wall of the first pipe body 403, a second spring 405 fixedly connected between the second sprinkler pipe 402 and the first sprinkler pipe 401, and a third sprinkler pipe 402 slidably connected to the inner wall of the second sprinkler pipe 402. The irrigation pipe 406 has a second pipe body 407 connected to its bottom end. A third pressure valve 408 is installed on the outer wall of the second pipe body 407. A third spring 409 is fixedly connected between the third irrigation pipe 406 and the second irrigation pipe 402. A water spray pipe 410 is rotatably connected to the top end of the third irrigation pipe 406. A water pressure driven 360° automatic rotating nozzle 411 is installed on the water spray pipe 410. The nozzle has guide vanes inside, which are inclined and rotate by using the reaction force of the water jet.

[0027] The operation process of this embodiment is as follows: Water from the regulating component 2 flows into the rectangular tube 302 through the connecting pipe 303. The water pressure pushes the moving tube 304 to slide along the first slide groove 103, stretching the first spring 307. The toothed plate 308 at the top of the moving tube 304 drives the spur gear 313 to rotate. Before the water pressure exceeds the threshold of the first pressure valve, the rotating shaft 312 rotates accordingly and, through the ear plate 314 and the mounting plate 315, turns the sprinkler assembly 4 from a horizontal state to a vertical state. This pure water pressure driven design does not require electricity or a complex electronic control system, has a low failure rate, and is suitable for large-area farmland. After the water pressure exceeds the threshold of the first pressure valve, the water flows into the first sprinkler pipe 401 through the outlet pipe 310 and the hose 311. When the water pressure does not reach the threshold of the second pressure valve 404, the water pressure continues to increase. Before the water pressure rises, the second sprinkler pipe 402 slides out along the first sprinkler pipe 401, stretching the second spring 405. When the water pressure further increases beyond the threshold of the second pressure valve 404 but not higher than the threshold of the third pressure valve 408, the third sprinkler pipe 406 slides out along the second sprinkler pipe 402, stretching the third spring 409. The three-stage telescopic structure significantly increases the sprinkler height and coverage radius, meeting the irrigation needs of orchards and tall crops. The water finally sprays out through the nozzle 411 on the sprinkler pipe 410. The water impacts the guide vanes, using the reaction force of the water jet to achieve 360° rotation, realizing multi-angle sprinkler irrigation and improving irrigation uniformity. By using water pressure to drive the device, maintenance-free operation can be achieved, further improving the convenience of use.

[0028] Example 3, please refer to Figure 1-12This embodiment three is an improvement on the first embodiment as follows: the positioning component 5 includes two fixed plates 501 fixedly connected to the outer wall of the first irrigation pipe 401, a rotating rod 502 fixedly connected between the two fixed plates 501, a support plate 503 rotatably connected to the outer wall of the rotating rod 502, a wedge block 504 that slides with the bottom of the housing fixedly connected to one end of the support plate 503, the wedge block 504 slides with the second sliding groove 104, a locking hole is provided on the inclined surface of the wedge block 504, the positioning component 5 also includes a locking rod 505 slidably inserted into one side of the housing, the locking rod 505 is inserted into the locking hole, a baffle 506 fixedly connected to one end of the locking rod 505, and a return spring 507 sleeved on the locking rod 505 fixedly connected between the baffle 506 and the housing.

[0029] The operation process of this embodiment is as follows: After the sprinkler assembly 4 completes its erection and multi-stage extension, it is mechanically locked to ensure the stability of the sprinkler process. When the sprinkler assembly 4 rotates with the mounting plate 315 to a vertical position and is fully extended, the first sprinkler pipe 401 synchronously drives the two fixed plates 501 on the outer wall to move. The rotating rod 502 between the fixed plates 501 will pull the support plate 503, thereby pulling the wedge block 504 to slide along the second sliding groove 104. When the wedge block 504 slides to the designated position, the locking rod 505 will... Under the elastic force of the return spring 507, it automatically inserts into the locking hole on the inclined surface of the wedge block 504 to complete the positioning of the sprinkler assembly 4. This purely mechanical locking method requires no additional power, responds quickly and is firm and reliable. It can effectively avoid the problem of the sprinkler assembly 4 shaking or shifting due to water pressure impact or external force disturbance during sprinkler irrigation, and ensure the uniformity of irrigation. When the water pressure drops after the sprinkler irrigation ends, it can be unlocked simply by pulling the baffle 506 at the end of the locking rod 505. The operation is convenient and can quickly realize the reset and storage of the sprinkler assembly 4.
