Description

Technical Field

[0001] This application relates to the technical field of sprinkler irrigation machines, and in particular to a reel-type sprinkler irrigation machine. Background Technology

[0002] Reel-type sprinkler irrigation machines can irrigate large areas of farmland, and the amount of water sprayed can be controlled according to the nozzles to meet the different requirements of users for irrigation water volume, making them a suitable choice for water-saving irrigation of farmland.

[0003] The existing reel-type sprinkler includes a frame, a reel rotatably mounted on the frame, a delivery pipe wound around the reel, a water turbine coaxially mounted inside the reel, a water supply assembly mounted on the frame for supplying water to the reel, and a sprinkler carriage. The inner end of the delivery pipe is connected to the reel, and the outer end of the delivery pipe is connected to a pre-set sprinkler on the sprinkler carriage. The water turbine is fixedly connected to the reel. When the reel-type sprinkler is performing sprinkler operation, the water supply assembly supplies water to the reel, and the water in the reel flows to the sprinkler through the delivery pipe. During the flow of the water in the reel, the water turbine is driven to rotate, which in turn drives the reel to rotate, thereby causing the rotating reel to rewind the delivery pipe.

[0004] During the operation of the aforementioned reel-type sprinkler irrigation machine, the water source provided by the water supply component is mostly surface water. However, surface water contains many impurities, and these impurities can enter the reel, increasing the likelihood of the water turbine getting stuck. This, in turn, increases the need for maintenance during the use of the sprinkler irrigation machine, making it inconvenient for the operator to use. At the same time, during the water flow, some of its energy is transferred to the water turbine, resulting in lower water pressure at the nozzles, which is also inconvenient for sprinkler irrigation operations. Summary of the Invention

[0005] To improve the ease of use of sprinkler irrigation machines, this application provides a reel-type sprinkler irrigation machine.

[0006] This application provides a reel-type sprinkler irrigation machine, which adopts the following technical solution: A reel-type sprinkler system includes: A frame, on which a reel is rotatably mounted, and on which a rotating shaft is coaxially inserted, which is rotatably connected to the frame and fixedly connected to the reel; The conveyor pipe is wound on the reel; A water supply component, connected to the inner end of the delivery pipe and used to supply water into the delivery pipe; A sprinkler truck is equipped with nozzles that are connected to the outer end of a delivery pipe. The drive assembly includes a motor mounted on a frame for driving the rotating shaft to rotate.

[0007] By adopting the above technical solution, when the sprinkler is working, the sprinkler truck drives the delivery pipe to unwind and extend. When the delivery pipe needs to be wound up, the motor is started, and the output shaft of the motor drives the rotating shaft to rotate, realizing the winding process of the delivery pipe. This avoids the influence of impurities in the water on the rotation process of the reel, and at the same time reduces the energy lost by the water in the reel during the process, so that the water flow sprayed from the nozzle can have a higher water pressure, thereby improving the ease of use of the sprinkler.

[0008] Optionally, the driving component further includes: A slewing bearing is coaxially sleeved on a rotating shaft and fixedly connected to the rotating shaft; The clutch bearing is coaxially mounted on the slewing bearing, and the inner ring of the clutch bearing is fixedly connected to the slewing bearing. The turbine is coaxially mounted on the clutch bearing and is fixedly connected to the outer ring of the clutch bearing and rotatably connected to the frame. The worm gear is rotatably connected to the frame and works in conjunction with the turbine. The worm gear is coaxial with the motor output shaft and is fixedly connected to the motor output shaft.

[0009] By adopting the above technical solution, when the motor output shaft is directly connected to the rotating shaft, the motor needs to be in the starting state to cooperate with the movement of the sprinkler truck when the conveying pipe is unwinding and extending; the setting of the slewing bearing and the clutch bearing allows the motor to be in the off state when the conveying pipe is unwinding and extending, which is convenient for the operator to use the sprinkler machine.

[0010] Optionally, a water supply chamber is provided inside the rotating shaft, and the inner end of the delivery pipe communicates with the water supply chamber; the water supply assembly includes: The water supply pipe has one end coaxially inserted into the rotating shaft and connected to the water supply chamber, and the other end is equipped with a water source. The end of the water supply pipe near the rotating shaft is fixedly connected to the frame. A water pump is installed on the water supply pipe.

[0011] By adopting the above technical solution, when the sprinkler machine is working, the water pump is started, and the water pump transports external water through the water supply pipe to the water supply chamber and the delivery pipe in sequence, so that the water in the delivery pipe flows to the sprinkler head and is sprayed out from the sprinkler head.

[0012] Optionally, the sprinkler machine is equipped with a positioning component, which includes: The positioning box is tilted downwards along the direction of the frame closer to the sprinkler truck and is fixedly connected to the frame. The slide bar is set parallel to the positioning box. The top of the slide bar is inserted into the positioning box and located inside the positioning box. The slide bar is slidably connected to the positioning box along its own length. The slider is slidably disposed inside the positioning box along the tilt direction and is fixedly connected to the slide rod. The slider divides the inside of the positioning box into a first chamber and a second chamber from top to bottom. The water supply component is used to supply water to the first chamber. A spring is set parallel to the slide rod and located in the first chamber. The two ends of the spring are fixedly connected to the positioning box and the slider, respectively.

[0013] By adopting the above technical solution, after the sprinkler is placed in the designated position, the water supply component supplies water to the delivery pipe, enabling the sprinkler head to spray water for irrigation. At the same time, the water supply component supplies water to the delivery pipe and also supplies water to the first chamber, causing the water in the first chamber to gradually increase. This causes the slider and slide rod to slide downwards under the pressure of the water in the first chamber, allowing the bottom end of the slide rod to be inserted into the ground, thus keeping the frame stable and facilitating the operation of the sprinkler truck. During operation, the sprinkler truck applies force to the frame through the delivery pipe in its direction of travel, which disrupts the stability of the connection between the slide rod and the ground at the initial insertion depth. As the water in the first chamber gradually increases, the depth of the slide rod into the ground gradually increases, allowing new connections to be continuously established between the slide rod and the ground. This ensures that the frame of the sprinkler truck can be placed stably during operation, making it easier for the operator to use the sprinkler.

[0014] Optionally, the water supply assembly further includes a connecting pipe, one end of which is connected to the water supply pipe and the other end of which is connected to the first chamber.

[0015] By adopting the above technical solution, water in the water supply pipe can be supplied to the first chamber through the connecting pipe, so that the slider and the slide rod can slide downward under the support of the water.

[0016] Optionally, the frame is equipped with an adjustment assembly and a power assembly, the adjustment assembly including: A support tube is connected to the side wall of the connecting tube. An adjustment groove is formed in an S-shape along the circumference of the inner wall of the support tube, and the two ends of the adjustment groove are connected. The adjustable telescopic rod is coaxially set with the support pipe. The movable end of the adjustable telescopic rod is rotatably connected to the frame around its own axis. The fixed end of the adjustable telescopic rod is located at the connection between the support pipe and the connecting pipe and abuts against the inner wall of the support pipe. When the fixed end of the adjustable telescopic rod abuts against the inner wall of the connecting pipe, the two ends of the connecting pipe are isolated. The power component is used to drive the adjustable telescopic rod to rotate around its own axis. Two sliding balls are provided and symmetrically arranged on both sides of the fixed end of the adjusting telescopic rod. The sliding balls are slidably arranged in the adjusting groove along the length of the adjusting groove.

[0017] By adopting the above technical solution, when the slide bar penetrates into the stratum and establishes a new connection with the stratum, the destructive effect exerted by the sprinkler truck on the frame through the delivery pipe will take a certain amount of time to break the connection between the slide bar and the stratum. As the water flows in the water supply pipe, the power component is activated, which drives the adjusting telescopic rod to rotate. This causes the fixed end of the adjusting telescopic rod to reciprocate along its own length under the action of the slider and the adjusting groove. During the reciprocating movement, the fixed end of the adjusting telescopic rod regulates the flow rate of the water in the connecting pipe. The flow rate regulation function of the connecting pipe at the fixed end of the telescopic rod allows the slide rod to slide down intermittently, thereby establishing a new connection between the slide rod and the ground. Then, the flow rate in the connecting pipe at the fixed end of the telescopic rod is gradually reduced until the two ends of the connecting pipe are completely isolated. This allows time for the sprinkler to break the new connection established between the slide rod and the ground, thus extending the positioning time of the slide rod on the frame.

[0018] Optionally, the power assembly includes: The power rod is set parallel to the adjusting telescopic rod. The power rod is rotatably connected to the frame around its own axis. The power rod is connected to the movable end of the adjusting telescopic rod via belt drive. The first bevel gear is fixedly sleeved on the rotating shaft; The second bevel gear is coaxially mounted with the power rod and fixedly connected to the top of the power rod. The second bevel gear meshes with the first bevel gear.

[0019] By adopting the above technical solution, the water in the water supply pipe drives the blades to rotate during the flow process, which in turn drives the power rod to rotate. The power rod, which is in a rotating state, drives the adjusting telescopic rod to rotate through belt transmission.

[0020] Optionally, the positioning box has an installation cavity inside its side wall; a slot is provided on the side of the slider near the installation cavity; a limiting groove is provided on the inner side wall of the first cavity to be aligned with the slot; the positioning box is provided with a limiting component and a transmission component, the limiting component including: The rotating rod is arranged parallel to the sliding rod and is rotatably mounted in the mounting cavity. The transmission assembly is used to drive the rotating rod to rotate around its own axis. The limiting block is slidably disposed in the slot along the direction of the slot close to the limiting slot, and one end of the limiting block can enter the limiting slot; The first magnetic sheet is fixedly mounted on the rotating rod. The first magnetic sheet can be positioned directly opposite the limiting block, and there is a mutual attraction between the first magnetic sheet and the limiting block. The second magnetic sheet is fixedly mounted on the rotating rod. The second magnetic sheet can be positioned directly opposite the limiting block, and there is a mutual repulsive force between the second magnetic sheet and the limiting block.

[0021] By adopting the above technical solution, when the rotating rod is in the initial static state, the first magnetic sheet and the limiting block are set opposite each other. At this time, one end of the limiting block is located in the limiting groove under the action of the first magnetic sheet, so that the position of the sliding rod is fixed. When the transmission component drives the rotating rod to rotate, the second magnetic sheet gradually approaches the limiting block, so that the limiting block slides into the slot under the action of the second magnetic sheet, thereby allowing the sliding rod to slide.

[0022] Optionally, the transmission assembly includes: The third bevel gear is coaxially sleeved on the rotating shaft and fixedly connected to the rotating shaft; The fourth bevel gear meshes with the third bevel gear; The fixed rod is coaxially arranged with the fourth bevel gear and fixedly connected to the fourth bevel gear. The fixed rod is rotatably connected to the frame around its own axis. The transmission rod is coaxially arranged with the rotating rod. One end of the transmission rod is inserted into the positioning box and fixedly connected to the rotating rod. The transmission rod is rotatably connected to the positioning box and connected to the fixed rod through belt drive.

[0023] By adopting the above technical solution, the rotating shaft drives the third bevel gear, the fourth bevel gear, and the fixed rod to rotate in sequence during the rotation process. The fixed rod, which is in a rotating state, drives the transmission rod and the rotating rod to rotate through belt transmission.

[0024] In summary, this application includes at least one of the following beneficial technical effects: By setting up drive and water supply components, when the sprinkler is working, the sprinkler truck drives the delivery pipe to unwind and extend. When the delivery pipe needs to be wound up, the motor is started, and the output shaft of the motor drives the rotating shaft to rotate, realizing the winding process of the delivery pipe. This avoids the impact of impurities in the water on the rotation of the reel, and at the same time reduces the energy lost by the water in the reel during the process, so that the water flow sprayed from the nozzle can have higher water pressure, thereby improving the ease of use of the sprinkler. By setting up positioning components, the sprinkler truck applies force to the frame through the delivery pipe in its running direction during operation, which disrupts the connection stability between the slide rod and the ground at the initial insertion depth. As the water in the first chamber gradually increases, the depth of the slide rod into the ground gradually increases, allowing new connections to be continuously established between the slide rod and the ground. This ensures that the frame of the sprinkler truck can be placed stably during operation, making it easier for the operator to use the sprinkler. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0028] This application discloses a reel-type 11 sprinkler irrigation machine. (Refer to...) Figure 1 and Figure 2 The reel-type sprinkler includes a frame 1, a delivery pipe 2, a water supply assembly 3, a sprinkler carriage 5, and a drive assembly 4. A reel 11 is rotatably mounted on the frame 1, and a rotating shaft 12, rotatably connected to the frame 1 and fixedly connected to the reel 11, is coaxially inserted on the reel 11. The delivery pipe 2 is wound around the reel 11. The water supply assembly 3 is connected to the inner end of the delivery pipe 2 and is used to supply water to the delivery pipe 2. A nozzle 51 is mounted on the sprinkler carriage 5 and is connected to the outer end of the delivery pipe 2. The drive assembly 4 is used to drive the rotating shaft 12 to rotate.

[0029] When using a sprinkler irrigation machine for irrigation operations, first, place the frame 1 in the designated position, then start the sprinkler truck 5. The sprinkler truck 5 moves in a straight line along its own running direction. When the sprinkler truck 5 reaches the preset position, start the water supply component 3. The water supply component 3 supplies water to the nozzles 51 on the sprinkler truck 5, so that water is sprayed from the nozzles 51 to irrigate the corresponding work area. When the sprinkler truck 5 needs to approach the frame 1, the drive component 4 can be started. The drive component 4 drives the rotating shaft 12 and the reel 11 to reverse, so that the delivery pipe 2 is in the winding state, and then the sprinkler irrigation machine approaches the frame 1 under the driving action of the delivery pipe 2 to complete the reset.

[0030] Reference Figure 1 and Figure 3 The rotating shaft 12 is located in the horizontal plane; a water supply chamber 121 is provided inside the rotating shaft 12 along its own length; the water supply assembly 3 includes a water supply pipe 31 and a water pump 33, wherein one end of the water supply pipe 31 is coaxially inserted into the rotating shaft 12 and communicates with the water supply chamber 121, and the other end is provided with a water source, and the end of the water supply pipe 31 near the rotating shaft 12 is fixedly connected to the frame 1; the water pump 33 is installed on the water supply pipe 31; the inner end of the delivery pipe 2 communicates with the water supply chamber 121.

[0031] When irrigation is required, the water pump 33 is started. The water pump 33 transports external water to the water supply chamber 121 through the water supply pipe 31. The water in the water supply chamber 121 flows to the delivery pipe 2 and the nozzle 51, so that external water can be sprayed out from the nozzle 51 and irrigation can be carried out.

[0032] Reference Figure 2 and Figure 4The drive assembly 4 is located on the side of the frame 1 away from the water supply assembly 3. The drive assembly 4 includes a motor 41, a rotary bearing 44, a clutch bearing 45, a turbine 43, and a worm gear 42. The rotary bearing 44 is coaxially sleeved on the rotating shaft 12 and fixedly connected to the rotating shaft 12. The clutch bearing 45 is coaxially sleeved on the rotary bearing 44, and the inner ring of the clutch bearing 45 is fixedly connected to the rotary bearing 44. The turbine 43 is coaxially sleeved on the clutch bearing 45 and fixedly connected to the outer ring of the clutch bearing 45. The turbine 43 is rotatably connected to the frame 1 around its own axis. The worm gear 42 is horizontally arranged above the turbine 43. The length direction of the worm gear 42 is the same as the radial direction of the rotating shaft 12. The worm gear 42 is rotatably connected to the frame 1 around its own axis and works in conjunction with the turbine 43. The motor 41 is mounted on the frame 1. The output shaft of the motor 41 is coaxially arranged with the worm gear 42 and fixedly connected to the output shaft of the motor 41.

[0033] When the sprinkler truck 5 moves away from the frame 1 under its own power, the sprinkler truck 5 drives the delivery pipe 2 to unwind, and the delivery pipe 2 drives the reel 11 and the rotating shaft 12 to rotate in the forward direction during the unwinding process. When the sprinkler truck 5 needs to be reset, the motor 41 is started. The output shaft of the motor 41 drives the screw to rotate. During the rotation of the screw, the screw drives the turbine 43 to rotate, so that the turbine 43 drives the rotating shaft 12 to rotate through the clutch bearing 45 and the slewing bearing 44. During the rotation of the rotating shaft 12, the reel 11 is driven to rotate, so that the delivery pipe 2 is wound up and reset. During the winding process, the delivery pipe 2 drags the sprinkler truck 5 to reset.

[0034] Reference Figure 1 and Figure 5The frame 1 is equipped with a positioning component 6 and a support component 13. The positioning component 6 is located on the side of the frame 1 near the water supply component 3. The positioning component 6 includes a positioning box 61, a slider 63, a sliding rod 62, and a spring 64. The positioning box 61 is elongated and is inclined downward along the direction of the frame 1 near the sprinkler truck 5, and is fixedly connected to the frame 1. The slider 63 is slidably disposed inside the positioning box 61 along the inclined direction of the positioning box 61, and the slider 63 divides the interior of the positioning box 61 into a first chamber 613 and a second chamber 614 from top to bottom. The spring 64 is located in the first chamber 613 and is arranged parallel to the inclined direction of the positioning box 61. The two ends of the spring 64 are respectively connected to the positioning box 61 and the slider. 63 is fixedly connected; the slide rod 62 is arranged parallel to the inclined direction of the positioning box 61, the top end of the slide rod 62 is inserted into the bottom end face of the positioning box 61 and located in the second chamber 614, the slide rod 62 is slidably connected to the positioning box 61 along its own length direction, and the top end of the slide rod 62 is fixedly connected to the slider 63; a first positioning shovel 65 is fixedly installed at the bottom end of the slide rod 62; the support member 13 is a telescopic rod structure, the support rod is located on the side of the frame 1 away from the positioning component 6, the support member 13 is arranged parallel to the slide rod 62, the fixed end of the support member 13 is fixedly connected to the frame 1, and a connecting rod 132 is fixedly installed between the movable end of the support member 13 and the slide rod 62; a second positioning shovel 131 is fixedly installed at the bottom of the movable end of the support member 13.

[0035] Reference Figure 1 and Figure 5 The water supply component 3 also includes a connecting pipe 32. One end of the connecting pipe 32 is inserted into the side wall of the water supply pipe 31 and is connected to the water supply pipe 31. The other end of the water supply pipe 31 is inserted into the top end face of the positioning box 61 and is connected to the first chamber 613. An adjustment component 7 and a power component 8 are provided on the frame 1. Both the adjustment component 7 and the power component 8 are located on the side of the frame 1 close to the water supply component 3.

[0036] Once the frame 1 is placed in the designated position, the water pump 33 is started, allowing external water to enter the water supply pipe 31. The water in the water supply pipe 31 can then enter the first chamber 613 through the connecting pipe 32. Under the pressure of the water, the slider 63 and the sliding rod 62 slide downwards, causing the first positioning shovel 65 to move downwards and insert into the stratum under the drive of the sliding rod 62. During the movement, the sliding rod 62 drives the movable end of the support rod to move through the connecting rod 132, allowing the second positioning shovel 131 and the first positioning shovel 65 to move synchronously and insert into the stratum together. Thus, the frame 1 is stably positioned by the first positioning shovel 65 and the second positioning shovel 131.

[0037] Reference Figure 6 and Figure 7The adjusting assembly 7 includes a support tube 71, an adjusting telescopic rod 72, and a slider 73. The support tube 71 is located above the connecting tube 32 and is vertically inserted into the side wall of the connecting tube 32. The support tube 71 is connected to and fixedly connected to the connecting tube 32. (Refer to...) Figure 7 and Figure 8 An adjustment groove 711 is formed in an S-shape on the inner wall of the support pipe 71 along its circumference, and the two ends of the adjustment groove 711 are connected. The adjustment telescopic rod 72 is coaxially arranged with the support pipe 71. The movable end of the adjustment telescopic rod 72 is located above the connecting pipe 32. The movable end of the adjustment telescopic rod 72 is rotatably connected to the frame 1 around its own axis. The fixed end of the adjustment telescopic rod 72 is located at the connection between the support pipe 71 and the connecting pipe 32 and abuts against the inner wall of the support pipe 71. When the fixed end of the adjustment telescopic rod 72 abuts against the inner wall of the connecting pipe 32, the two ends of the connecting pipe 32 are isolated. Two sliding balls 73 are provided and symmetrically arranged on both sides of the fixed end of the adjustment telescopic rod 72. The sliding balls 73 are fixedly connected to the fixed end of the adjustment telescopic rod 72 and are slidably arranged in the adjustment groove 711 along the length direction of the adjustment groove 711.

[0038] Reference Figure 6 and Figure 9 The power assembly 8 includes a power rod 81, a first bevel gear 82, and a second bevel gear 83. The first bevel gear 82 is coaxially sleeved on the rotating shaft 12 and located on the side of the water pump 33 near the frame 1. The first bevel gear 82 is fixedly connected to the rotating shaft 12. The second bevel gear 83 is horizontally arranged below the rotating shaft 12 and located between the water pump 33 and the first bevel gear 82. The second bevel gear 83 meshes with the first bevel gear 82. The power rod 81 is coaxially arranged below the second bevel gear 83. The top end of the power rod 81 is fixedly connected to the second bevel gear 83. The power rod 81 is rotatably connected to the frame 1 around its own axis. The power rod 81 and the movable end of the adjusting telescopic rod 72 are both fixedly sleeved with first pulleys, and a first belt is wound between the two first pulleys.

[0039] During the movement of the sprinkler truck 5, the rotating shaft 12 is always rotating. When the rotating shaft 12 rotates, it sequentially drives the first bevel gear 82, the second bevel gear 83, and the power rod 81 to rotate. The power rod 81 drives the adjusting telescopic rod 72 to rotate via belt drive. During the rotation of the adjusting telescopic rod 72, it drives the slider 73 to rotate in the adjusting groove 711, so that the fixed end of the adjusting telescopic rod 72 moves back and forth in the vertical direction during the rotation. When the slider 73 moves to the bottom of the adjusting groove 711, the bottom surface of the adjusting telescopic rod 72 abuts against the inner wall of the connecting pipe 32. At this time, the two ends of the connecting pipe 32 are isolated. Thus, by moving the fixed end of the adjusting telescopic rod 72, external water enters the first chamber 613 intermittently, thereby allowing the slider 63 and the slider 62 to slide downward intermittently.

[0040] Reference Figure 5 and Figure 10The positioning box 61 has an installation cavity 611 inside its side wall, located on the side of the positioning box 61 away from the frame 1; the slider 63 has a slot 631 on its side near the installation cavity 611; the inner side wall of the first chamber 613 has a limiting groove 612 that is directly opposite the slot 631; the positioning box 61 is provided with a limiting component 9, which includes a rotating rod 91, a limiting block 92, a first magnetic piece 93, and a second magnetic piece 94, wherein the length direction of the rotating rod 91 is the same as the length direction of the slider 62, the rotating rod 91 is located in the installation cavity 611, and rotates around its own axis relative to the positioning box 61. The limiting block 92 is slidably disposed in the slot 631 along the direction of the slot 631 near the limiting groove 612, and the end of the limiting block 92 near the limiting groove 612 can slide into the limiting groove 612; the first magnetic sheet 93 and the second magnetic sheet 94 are symmetrically disposed on both sides of the rotation and are fixedly connected to the rotating rod 91. The first magnetic sheet 93 and the second magnetic sheet 94 can be directly opposite the limiting block 92. There is a mutual attraction between the first magnetic sheet 93 and the limiting block 92, and there is a mutual repulsion between the second magnetic sheet 94 and the limiting block 92. When the conveying pipe 2 is not extended, the first magnetic sheet 93 is directly opposite the limiting block 92.

[0041] It should be noted that the side of the limiting block 92 closest to the mounting cavity 611 can abut against the bottom surface of the limiting groove 612, and there is a distance between the limiting block 92 and the side of the limiting groove 612 to facilitate one end of the limiting block 92 entering the limiting groove 612.

[0042] Reference Figure 9 and Figure 10 A transmission assembly 0 is provided on the side of the frame 1 near the positioning box 61. The transmission assembly 0 includes a third bevel gear 01, a fourth bevel gear 02, a fixed rod 03, and a transmission rod 04. The third bevel gear 01 is coaxially sleeved on the rotating shaft 12 and fixedly connected to the rotating shaft 12. The fourth bevel gear 02 is located on the side of the third bevel gear 01 near the sprinkler truck 5 and meshes with the third bevel gear 01. The length direction of the fixed rod 03 is the same as the length direction of the rotating rod 91, and the fixed rod 03 is connected to the fourth bevel gear. 02 is coaxially arranged and located on the side of the fourth bevel gear 02 away from the third bevel gear 01. The top of the fixed rod 03 is fixedly connected to the fourth bevel gear 02 and rotatably connected to the frame 1 around its own axis. The transmission rod 04 is coaxially arranged with the rotating rod 91. One end of the transmission rod 04 is inserted into the positioning box 61 and fixedly connected to the rotating rod 91. The transmission rod 04 is rotatably connected to the positioning box 61. A second pulley is fixedly sleeved on both the transmission rod 04 and the fixed rod 03. A second belt is wound between the two second pulleys.

[0043] During the rotation of the rotating shaft 12, the third bevel gear 01, the fourth bevel gear 02, and the fixed rod 03 are driven to rotate in sequence. During the rotation of the fixed rod 03, the transmission rod 04 is driven to rotate through the belt drive, which in turn drives the rotating rod 91, the first magnetic piece 93, and the second magnetic piece 94 to rotate. This causes the limiting block 92 to enter the slot 631 under the action of the second magnetic piece 94, thereby allowing the water in the connecting pipe 32 to enter the first chamber 613 and drive the slider 63 and the sliding rod 62 to slide downwards.

[0044] After the sprinkler irrigation operation is completed, the water pump 33 is started. The water pump 33 discharges the water in the water supply pipe 31 and the connecting pipe 32, so that the stretched spring 64 can restore its elastic deformation. In turn, the spring 64 drives the slider 63 and the slide rod 62 to move upward and return to the initial position. After the slider 63 returns to the initial position, one end of the limiting block 92 enters the limiting groove 612 under the action of the first magnetic piece 93, completing the positioning function of the slider 63 and the slide rod 62.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
