Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, specifically to a translational rotary sprinkler irrigation machine for agricultural irrigation. Background Technology

[0002] In agricultural irrigation, scientific water management is the core of improving crop yield, saving water resources, and ensuring soil health. Sprinkler irrigation is a commonly used method in the irrigation process. The translational rotary sprinkler is a high-efficiency agricultural irrigation equipment that combines linear movement and sprinkler rotation. It is mainly used for uniform irrigation of large areas of farmland. Its core feature is that the overall movement direction is controlled by the translational track system, and the sprinkler can rotate at multiple angles to achieve flexible, water-saving, and precise irrigation.

[0003] In the prior art, Chinese Patent Application No. CN202311574421.0 discloses a translational sprinkler irrigation device, including a sprinkler irrigation mechanism for irrigating farmland. The sprinkler irrigation mechanism includes a connecting pipe, with mounting pipes installed at both ends of the connecting pipe. Several sprinkler irrigation components are installed at the bottom of the mounting pipe. Each sprinkler irrigation component includes a water spraying element, a traveling element on the outside of the water spraying element, a water supply element fixed on the water spraying element, and a guide element on the water supply element. The guide element is located on the mounting pipe. This invention is a translational sprinkler irrigation device.

[0004] For example, in the prior art, Chinese Patent Application No. CN202011544910.8 discloses a translational sprinkler irrigation machine. In view of the problem of uneven irrigation in existing sprinkler irrigation machines, the following solution is proposed: it includes two movable frames, multiple movable wheels are fixed at the bottom of the movable frames, an opening is opened through the movable frames, a first support rod is fixed in the opening, a second support rod is fixed between the two first support rods, a connector pipe is fixed through one side of the movable frames, a main water pipe is fixed between the two movable frames, and a rotating mechanism includes a water distribution pipe. Two support rods are fixed on both sides of the water distribution pipe, a force plate is fixed at the top of the support rods, a water distribution plate is connected to the top of the water distribution pipe, and multiple first nozzles are connected to the outer circumference of the water distribution plate.

[0005] For example, in the prior art, Chinese patent application number CN201610484845.1 discloses a translational sprinkler irrigation machine, which consists of one or more spans. Each span includes a main sprinkler irrigation water supply pipe, a support frame, sprinkler head branch pipes, and a traveling support. The bottom of the traveling support is equipped with traveling wheels, and the traveling support is equipped with a power system and a support frame. The two ends of the main sprinkler irrigation water supply pipe are rigidly connected to the support frames on the two traveling supports. Multiple water spray pipes are evenly spaced on the main sprinkler irrigation water supply pipe. It also includes a fertilizer main pipe. A vertical support rod is provided on the support frame. The fertilizer main pipe and the vertical support rod are connected in an adjustable manner. Multiple micro-fertilizer spray pipes are evenly spaced on the fertilizer main pipe.

[0006] Based on the above information, it can be seen that existing translational sprinkler irrigation machines generally use drive rollers on both sides to move the irrigation nozzles that span across the farmland, achieving the purpose of translational irrigation. However, in actual use, since the two moving rollers have two drive systems and the terrain and water conditions on both sides of the farmland are different, it is impossible to ensure that the drive rollers on both sides move in unison. When there is a difference in movement speed, the entire spanning mechanism will be twisted, which can easily damage the overall structure of the device. Summary of the Invention

[0007] The purpose of this invention is to provide a translational rotary sprinkler irrigation machine for agricultural irrigation, so as to solve the problem of cross-span twisting and damage caused by inconsistent movement speeds on both sides as mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a horizontally arranged support base, with movable rollers rotatably mounted on the side of the support base, and a mounting frame fixedly mounted on the upper surface of the support base. A filter box is fixedly mounted at the middle position of the upper surface of the support base, and a conveying pipe spanning the left and right sides of the farmland is fixedly installed above the filter box. A conveying pump is installed at the bottom end of the conveying pipe, and a stabilizing frame is provided below the conveying pipe. The stabilizing frame is divided into a first frame and a second frame, and a telescopic mechanism is provided between the first frame and the second frame. The first frame is fixedly mounted on the upper surface of the support turntable, and an arc-shaped limiting baffle located outside the support turntable is fixedly mounted on the upper surface of the mounting frame, and an alarm mechanism is provided between the limiting baffle and the support turntable. A water outlet pipe is installed through the lower end of the second frame, and an irrigation nozzle is rotatably mounted at the lower end of the water outlet pipe.

[0009] Preferably, a water pipe is fixedly installed through the side of the filter box and extends into the water channel, and a sponge filter cotton is fixedly installed inside the filter box.

[0010] Preferably, a rotating sleeve and a telescopic sleeve are symmetrically installed at the left and right ends of the conveying pipeline. The rotating sleeve is sealed to the conveying pipeline during rotation (the rotating sleeve is fitted onto the outside of the conveying pipeline, and the two can rotate and are sealed by an internal sealing ring), and the telescopic sleeve is sealed to the conveying pipeline during telescopic movement (the telescopic sleeve is also fitted onto the outside of the conveying pipeline, and the two can slide relative to each other and are sealed by an internal sealing ring).

[0011] Preferably, the telescopic mechanism includes a connecting frame installed between the first frame and the second frame, and a connecting sleeve is fixedly installed at the top of the connecting frame, and the connecting sleeve slides through both the first frame and the second frame.

[0012] Preferably, the alarm mechanism includes an audible and visually synchronized alarm fixedly installed on the upper surface of the support turntable, and the side of the support turntable slides against the inner wall of the limiting baffle, and an energized contact electrically connected to the alarm is fixedly installed on the outer surface of the support turntable.

[0013] Preferably, the lower surface of the support turntable contacts friction balls rotatably mounted on the upper surface of the mounting bracket, and an energized contact strip is fixedly installed on the inner side wall of the limiting baffle.

[0014] Preferably, when the energized contact strip contacts the energized contact point, it connects to supply power to the alarm, and a storage battery for supplying power to the energized contact strip is fixedly installed on the lower surface of the mounting bracket.

[0015] Preferably, a connecting ring with a groove structure is fixedly installed at the middle position of the upper surface of the mounting bracket, and a buffer pad made of spring material is fixedly installed inside the connecting ring. A limit slider is fixedly installed on the lower surface of the support turntable, and the limit slider and the connecting ring form a sliding structure.

[0016] Preferably, the water outlet pipe and the first frame form a through-type vertical sliding structure, and a telescopic cylinder is rotatably installed between the upper end of the water outlet pipe and the first frame. The water outlet pipe is connected to the delivery pipe via a connecting hose at its upper end.

[0017] Preferably, a drive blade is fixedly installed on the upper surface of the irrigation nozzle, and a diversion nozzle is fixedly installed on the lower side of the water outlet pipe, and the outlet of the diversion nozzle has an inclined structure corresponding to the drive blade.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This translational rotary agricultural irrigation sprinkler machine adopts a novel structural design, the specific details of which are as follows:

[0019] 1. The drive mechanism drives the moving rollers to rotate, thereby moving the entire device horizontally in the farmland. During this process, water is drawn from the corresponding irrigation canal through the pumping pipe and sprayed out from the irrigation nozzle to achieve the purpose of irrigating the crops. When the moving rollers on both sides are not at the same speed, the connection between the conveying pipe and the rotating sleeve can rotate, and the connection between the conveying pipe and the telescopic sleeve can extend and retract, thereby avoiding the twisting of the conveying pipe.

[0020] Furthermore, a telescopic mechanism is also installed in the stabilizing frame below the conveying pipeline. The stabilizing frame is divided into two parts: a first frame and a second frame. A connecting frame is installed between the first frame and the second frame. When the speeds on both sides are inconsistent, the first frame can drive the support turntable to rotate. At the same time, the first frame and the second frame slide relative to the connecting sleeve at the top of the connecting frame, thereby preventing the stabilizing frame from twisting.

[0021] 2. During the rotation of the support turntable, the energized contacts on its outer side move. When the energized contacts move to the inside of the limit baffle (indicating that the rotation angle of the support turntable is large, thus reflecting that the speed difference between the two sides is too large), the energized contacts come into contact with the energized contact strip on the inner wall of the limit baffle. At this time, the power supply of the battery, combined with the conduction between the energized contacts and the energized contact strip, activates the alarm to emit an audible and visual signal to remind the staff to adjust the device and prevent the speed difference between the two sides from increasing and causing danger.

[0022] Furthermore, as the support turntable rotates, it drives the limiting slider fixedly installed on its lower surface to move synchronously. At this time, the limiting slider slides in the groove above the connecting ring. After the limiting slider slides to a certain position, it will squeeze the buffer pad, and the elasticity of the buffer pad will be used to achieve the purpose of buffering.

[0023] 3. By opening the telescopic cylinder, the water outlet pipe can be moved up and down, thereby changing the height of the irrigation nozzle to adapt to the irrigation operation of crops at different stages. During irrigation, a small portion of the water in the outlet pipe is pressurized and sprayed out from the diversion nozzle, so that the sprayed water impacts the driving blades, and the driving blades drive the irrigation nozzle to rotate when impacted, thereby improving the uniformity of irrigation.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Example 1: Please refer to Figures 1-4 To achieve the purpose of translational and rotating irrigation, this embodiment provides the following technical solution, specifically: a horizontally positioned support base 1, with movable rollers 101 rotatably mounted on the side of the support base 1, and a mounting frame 2 fixedly mounted on the upper surface of the support base 1. A filter box 3 is fixedly mounted in the middle of the upper surface of the support base 1, and a conveying pipe 4 spanning the left and right sides of the farmland is fixedly installed above the filter box 3. A conveying pump 401 is installed at the bottom of the conveying pipe 4, and a stabilizing frame 5 is provided below the conveying pipe 4. A water pumping pipe 301 extending into the irrigation ditch is fixedly installed on the side of the filter box 3, and the interior of the filter box 3 is fixedly... A filter cotton 302 made of sponge material is fixedly installed. The water outlet pipe 6 and the first frame 501 form a through-type up-and-down sliding structure. The water outlet pipe 6 is installed through the lower end of the second frame 502. The water outlet pipe 6 is rotatably installed at the lower end of the water outlet pipe 6. The telescopic cylinder 22 is rotatably installed between the upper end of the water outlet pipe 6 and the first frame 501. The water outlet pipe 6 is connected to the delivery pipe 4 through the upper connecting hose 23. The driving blade 24 is fixedly installed on the upper surface of the water outlet pipe 7. The diversion nozzle 25 is fixedly installed on the lower side of the water outlet pipe 6. The outlet of the diversion nozzle 25 is inclined to correspond to the driving blade 24.

[0038] When using the device, first turn on the drive unit (electric drive or internal combustion engine drive) to rotate the moving roller 101, causing the moving roller 101 to move the support base 1. The support bases 1 on both sides move synchronously under the drive of the moving roller 101, thereby causing the conveying pipe 4 spanning the farmland to move horizontally. During this process, turn on the conveying pump 401 to pump water from the canal into the filter box 3 through the water pumping pipe 301. The lower end of the water pumping pipe 301 extends into the corresponding dedicated canal. After the water is filtered by the filter cotton 302 in the filter box 3, it is delivered to the conveying pipe. In step 4, the water is then transported to the outlet pipe 6 via the connecting hose 23, and finally sprayed out from the irrigation nozzle 7 at the lower end to achieve the purpose of irrigation of crops. During this process, the telescopic cylinder 22 is activated according to the height of the crops. The telescopic cylinder 22 drives the outlet pipe 6 to slide up and down relative to the stabilizer 5, thereby changing the up and down movement of the irrigation nozzle 7. During irrigation, a small portion of the water in the outlet pipe 6 is pressurized and sprayed out from the diversion nozzle 25. The sprayed water impacts the drive blade 24, causing the drive blade 24 to drive the irrigation nozzle 7 to rotate, improving the uniformity of irrigation.

[0039] Example 2: Please refer to Figures 5-7 In order to prevent torsion and deformation, this embodiment provides the following technical solution, which specifically discloses: the stabilizer 5 is divided into two parts, a first frame 501 and a second frame 502, and a telescopic mechanism is provided between the first frame 501 and the second frame 502; the first frame 501 is fixedly installed on the upper surface of the support turntable 12, and an arc-shaped limiting baffle 14 located outside the support turntable 12 is fixedly installed on the upper surface of the mounting frame 2; a rotating sleeve 8 and a telescopic sleeve 9 are symmetrically installed at the left and right ends of the conveying pipe 4; the rotating sleeve 8 rotates in a sealed manner with the conveying pipe 4, and the telescopic sleeve 9 extends and seals with the conveying pipe 4; the telescopic mechanism includes a connecting frame 10 installed between the first frame 501 and the second frame 502, and a connecting sleeve 11 is fixedly installed at the top of the connecting frame 10, and the connecting sleeve 11 slides through both the first frame 501 and the second frame 502.

[0040] When the rotational speeds of the two moving rollers 101 become inconsistent due to various factors (such as terrain, power, etc.), the entire device will tilt. During this process, the connection between the conveying pipe 4 and the rotating sleeve 8 rotates. The rotating sleeve 8 is fitted onto the outside of the conveying pipe 4, and both can rotate and are sealed by an internal sealing ring. At the same time, the connection between the conveying pipe 4 and the telescopic sleeve 9 slides and extends. The telescopic sleeve 9 is also fitted onto the outside of the conveying pipe 4, and both can slide relative to each other and are sealed by an internal sealing ring. By using rotation and sliding to prevent the conveying pipe 4 from twisting and deforming, the first frame 501 drives the support turntable 12, which is fixedly installed thereto, to rotate above the mounting frame 2. The support turntable 12 contacts the friction balls 13 below, using rolling friction to reduce friction, while the limiting baffle 14 limits the support turntable 12. At the same time, the first frame 501 and the second frame 502 slide relative to the connecting sleeve 11 at the top of the connecting frame 10, which also prevents the overall twisting and deformation of the stabilizing frame 5, thereby protecting the device to the greatest extent when the speeds on both sides are different.

[0041] Example 3: Please refer to Figures 8-11 To achieve timely alarm, this embodiment provides the following technical solution, specifically: an alarm mechanism is provided between the limiting baffle 14 and the supporting turntable 12; the alarm mechanism includes an audible and visually synchronized alarm 15 fixedly installed on the upper surface of the supporting turntable 12, and the side of the supporting turntable 12 slides against the inner wall of the limiting baffle 14, and an energized contact 16 electrically connected to the alarm 15 is fixedly installed on the outer surface of the supporting turntable 12, and a friction ball 13 rotatably installed on the upper surface of the mounting bracket 2 on the lower surface of the supporting turntable 12. The inner wall of the limiting baffle 14 is fixedly installed with an energized contact strip 17. When the energized contact strip 17 contacts the energized contact 16, it connects the power supply to the alarm 15. The lower surface of the mounting bracket 2 is fixedly installed with a battery 18 for supplying power to the energized contact strip 17. The middle position of the upper surface of the mounting bracket 2 is fixedly installed with a connecting ring 19 having a groove structure. The connecting ring 19 has a spring material buffer pad 21 fixedly installed inside. The lower surface of the supporting turntable 12 is fixedly installed with a limiting slider 20. The limiting slider 20 and the connecting ring 19 form a sliding structure.

[0042] During the rotation of the support turntable 12, the limiting slider 20 fixedly installed on its lower surface slides inside the connecting ring 19. When the limiting slider 20 moves to a certain position, it squeezes the buffer pad 21 inside the connecting ring 19, using the elasticity of the buffer pad 21 to achieve the purpose of buffering. During the rotation of the support turntable 12, the energized contact 16 on its outer side moves synchronously. When the energized contact 16 rotates to the inner side of the limiting baffle 14, it indicates that the support turntable 12 has rotated at least 30°. 30° is the maximum safe range obtained through testing; it needs to be stopped if it exceeds 30°. At this time, the energized contact 16 contacts the energized contact strip 17 on the inner side of the limiting baffle 14 to conduct current. At this time, the electrical energy in the battery 18 below the mounting bracket 2 powers the alarm 15 through the energized contact strip 17 and the energized contact 16, thereby activating the alarm 15 and emitting an audible and visual signal to remind the staff to stop the device in time and adjust its position.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
