Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, and specifically to a truss of a self-propelled sprinkler. Background Art

[0002] Sprinkler irrigation technology is one of the current advanced high-efficiency water use technologies, and it is also a high-tech that can be industrialized. It is an important feature of modern agricultural water-saving technology. It has the advantages of water saving, labor saving, soil conservation, fertilizer conservation, etc., with obvious yield-increasing effects, prominent economic and social benefits, and is widely applied and promoted in many agricultural planting areas. With the continuous progress of science and technology and the rapid development of society, the agricultural planting field has also developed rapidly. When planting crops, in case of a dry season, it is necessary to irrigate the crops to ensure the normal growth of the crops. Therefore, irrigation equipment is needed, and the reel-type sprinkler is one of the irrigation equipment. A reel-type sprinkler refers to a sprinkler that is supplied with water by a hose, winds the hose around a reel, and pulls a long-range sprinkler head to move the sprinkler head along the operation route during the sprinkler irrigation process.

[0003] Currently, the existing sprinkler's walking drive relies on a complex external traction device, which is inconvenient for automatic walking, resulting in poor mobility of the overall equipment. Moreover, when the truss equipment is pulled by the traction device and walks passively, it will repeatedly roll over the crops, causing relatively large damage and being unfavorable to the growth of the crops. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A truss of a self-propelled sprinkler, comprising: A vehicle frame, and a winding wheel installed on the top of the vehicle frame. Wheels are installed at the bottom of the vehicle frame, and a water pipe is wound around the surface of the winding wheel; A walking mechanism, which is used for irrigating crops and for self-walking, and is installed at the end of the vehicle frame surface; Among them, the walking mechanism includes a truss main body, driving wheels and auxiliary wheels. The truss main body is installed at the end of the surface of the vehicle frame. The driving wheels and auxiliary wheels are installed at the bottom of the truss main body. A transmission is fixedly installed at one end of the truss main body away from the vehicle frame. A power source is installed at the top of the surface of the transmission. A mud cleaning plate is fixedly installed at the side of the surface of the truss main body. An arc-shaped gradient plate is fixedly installed at the top of the inner side of the truss main body. An irrigation component is installed in the middle of the top of the truss main body. By the rolling of the wheels, the vehicle frame is driven to move, and the vehicle frame can be moved to a designated position in the farmland. Then, the pin shaft between the truss main body and the vehicle frame is removed, so that the truss main body is separated from the vehicle frame. Under the support of the driving wheels and auxiliary wheels, the truss main body stably supports the irrigation component. And through the transmission of the driving force by the transmission, the driving wheels roll. Combined with the rolling connection of the auxiliary wheels, the truss main body drives the irrigation component to move by itself without the traction of a traction device, and the crops are not easily crushed by the traction device, reducing the damage to the crops. The irrigation component includes a cylinder and a cylinder. The cylinder is hinged at the middle of the top of the truss main body. The cylinder is hinged at the side of the top of the truss main body. A connecting water channel is rotatably installed inside the cylinder. A water spray head is communicated at the top of the connecting water channel. A force-receiving tooth is fixedly connected to the bottom of the outer circular surface of the connecting water channel. A torsion spring is fixedly connected between the surface of the force-receiving tooth and the bottom of the cylinder. A rotating connector is installed between the bottom end of the connecting water channel and the water outlet of the water pipe. By connecting the water pipe with the connecting water channel, and through the water delivery of the water pipe, the water body enters the inside of the connecting water channel under the action of water pressure and sprays out from the water spray head to the position of the crops, so as to irrigate the crops.

[0005] Preferably, the output shaft of the power source is transmission-installed with the driving wheel through the transmission. The driving wheels and auxiliary wheels are evenly distributed at the bottom of the truss main body. The mud cleaning plate is installed directly above the driving wheel.

[0006] By the elongation of the telescopic end of the cylinder, a pulling force can be applied to the cylinder. The cylinder will drive the connecting water channel to rotate counterclockwise to adjust the angle, and then the water spray head can be driven to rotate together by the connecting water channel, so that the water spray port of the water spray head sprays water obliquely upward, making the water body sprayed by the water spray head farther, extending the spraying distance of the water spray head for the water body, and effectively irrigating the crops.

[0007] Preferably, the cylinder and the connecting water channel are both vertically installed, and the connecting water channel passes through the center of the cylinder. The water spray head, the connecting water channel and the water pipe are communicated with each other. As the cylinder is pulled by the telescopic end of the air cylinder, when the telescopic end of the air cylinder drives the connecting water channel to rotate counterclockwise, the force-bearing tooth will be driven by the connecting water channel to move together, and the roller at the end of the force-bearing tooth contacts the arc-shaped gradient surface at the side of the arc-shaped gradient plate, so that the arc-shaped gradient plate applies an outward driving force to the force-bearing tooth, and then the connecting water channel can be rotated along the central axis of the cylinder. The torque spring is elastically deformed under the torque force, and the water spray head is driven to rotate together, so that the water spray range of the water spray head can be increased, the irrigation range of the crops is wide, and the water outlet of the water pipe is rotationally connected through the connecting water channel of the rotating connector, so that the connecting water channel drives the water spray head to rotate smoothly and the angle adjustment is smooth, and the situation of structural jamming is not easy to occur.

[0008] Preferably, the air cylinder is installed obliquely, and the telescopic end of the air cylinder is hinged to the outer circular surface of the cylinder. The bottom of the connecting water channel passes through the center of the torque spring.

[0009] Preferably, a guiding mechanism is installed at the side of the interior of the vehicle frame. The guiding mechanism includes a round rod support frame. Both ends of the round rod support frame are fixedly installed on the inner side surface of the vehicle frame by screws. A first guide wheel is installed on one side of the top of the round rod support frame in a rolling manner. A second guide wheel is installed on the top of the round rod support frame and far away from the first guide wheel in a rolling manner. One end of the water pipe extending to the outside of the winding wheel passes through the top of the first guide wheel and the top of the second guide wheel. Circular push pieces are fixedly connected to both sides of the outer circular surface of the second guide wheel. A cleaning component is installed in the middle of the top of the round rod support frame. The water outlet end of the water pipe extends outward from the bottom of the winding wheel and passes through the top of the first guide wheel and the top of the second guide wheel. Combined with the water pipe fitting with the groove in the middle of the first guide wheel and the groove in the middle of the second guide wheel, when the water pipe is driven to move out and retract, the first guide wheel and the second guide wheel can be driven to roll. By using rolling friction, the friction force is reduced, and the water pipe is guided, so that the water pipe moves smoothly and the situation of jamming is not easy to occur.

[0010] Preferably, the first guide wheel and the second guide wheel are installed at the same height, and the surface of the water pipe fits with the groove in the middle of the first guide wheel and the groove in the middle of the second guide wheel.

[0011] Preferably, the cleaning component includes a connecting guide rod. The connecting guide rod is fixedly connected to the top of the round rod support frame. A connecting tooth is slidably mounted on the surface of the connecting guide rod. A return spring is fixedly connected between the surface of the connecting tooth and the surface of the round rod support frame. The top of the connecting tooth is fixedly connected to a conical cleaning hopper. The water pipe passes through the center of the conical cleaning hopper. By using the water pipe passing through the center of the conical cleaning hopper and with the continuous movement of the water pipe, the sundries attached to the surface of the water pipe can be scraped off by the conical cleaning hopper, and the sundries on the surface of the water pipe can be cleaned.

[0012] Preferably, the connecting guide rod passes through the center of the return spring. The connecting tooth is inclined. There are two connecting teeth, and the two connecting teeth are symmetrically installed along the central axis of the middle of the conical cleaning hopper. By the rolling of the second guide wheel, the circular push piece can be driven to rotate together. By using the edge of the circular push piece contacting the surface of the connecting tooth, the connecting tooth is subjected to the driving force of the circular push piece, and under the guiding action of the connecting guide rod, the connecting tooth drives the conical cleaning hopper to slide, and the return spring is compressed. As the circular push piece continues to rotate, the circular push piece is separated from the connecting tooth, the driving force received by the connecting tooth disappears, and under the elastic force of the return spring, the connecting tooth drives the conical cleaning hopper to move in the reverse direction. By reciprocating movement of the conical cleaning hopper, the sundries on the surface of the water pipe can be scraped multiple times.

[0013] Preferably, an auxiliary mechanism is installed at one end of the top of the vehicle frame away from the truss main body. The auxiliary mechanism includes an electric telescopic rod and a pressing connecting rod. The bottom of the electric telescopic rod is hinged to the side of the inner surface of the vehicle frame. The bottom end of the pressing connecting rod is hinged to one end of the top of the vehicle frame away from the truss main body. The telescopic end of the electric telescopic rod is hinged to the surface of the pressing connecting rod. An elastic piece is fixedly installed at the top of the pressing connecting rod. A pressing roller is rotatably installed at one end of the elastic piece away from the top of the pressing connecting rod. The outer circumferential surface of the pressing roller is attached to the surface of the water pipe. By the contraction of the telescopic end of the electric telescopic rod, a pulling force can be applied to the pressing connecting rod, and the elastic piece and the pressing roller can be driven to rotate counterclockwise and adjust the angle by the pressing connecting rod, so that the outer circumferential surface of the pressing roller is attached to the surface of the water pipe, and the water pipe can be rolled and pressed. Thus, when the winding wheel winds and unwinds the water pipe, the water pipe in the middle of the winding wheel always remains in a tight state and will not be disordered. And by using the elastic piece to elastically support the pressing roller, the water pipe is elastically pressed, and it is not easy to damage the water pipe, playing a protective role.

[0014] Preferably, both the electric telescopic rod and the pressing connecting rod are inclined. There are two pressing connecting rods, and the two pressing connecting rods are symmetrically installed along the pressing roller. The elastic piece is arc-shaped.

[0015] The present invention provides a self-propelled sprinkler truss. It has the following beneficial effects: 1. The truss of the self-propelled sprinkler moves the vehicle frame through the rolling of the wheels, so that the vehicle frame can be moved to the designated position in the farmland. Then, the pin shaft between the truss main body and the vehicle frame is removed, separating the truss main body from the vehicle frame. Supported by the driving wheels and auxiliary wheels, the truss main body stably supports the irrigation components. With the transmission of the driving force by the transmission, the driving wheels roll, and combined with the rolling connection of the auxiliary wheels, the truss main body drives the irrigation components to move by itself without the traction of a traction device, and the crops are not easily crushed by the traction device, reducing damage to the crops.

[0016] 2. The truss of the self-propelled sprinkler uses a water pipe to communicate with the connecting water channel. Through the conveyance of water by the water pipe, water enters the interior of the connecting water channel under the action of water pressure and sprays from the sprinkler head towards the crops, thus irrigating the crops.

[0017] 3. The truss of the self-propelled sprinkler uses the elongation of the telescopic end of the cylinder to apply a pulling force to the cylinder. The cylinder drives the connecting water channel to rotate counterclockwise to adjust the angle, and then drives the sprinkler head to rotate together through the connecting water channel, making the water outlet of the sprinkler head spray obliquely upward, so that the water sprayed by the sprinkler head can be farther, extending the spraying distance of the sprinkler head for the water, and effectively irrigating the crops.

[0018] 4. The truss of the self-propelled sprinkler uses the arc-shaped gradient plate to apply an outward pushing force to the force-bearing teeth, so that the connecting water channel rotates along the central axis of the cylinder. The torque spring undergoes elastic deformation under the torque force, and the sprinkler head is driven to rotate together, increasing the spraying range of the sprinkler head, making the irrigation range of the crops wide. The water outlet of the water pipe is rotationally connected to the connecting water channel through a rotary connector, making the connecting water channel drive the sprinkler head to rotate smoothly and adjust the angle smoothly, and it is not easy to have a situation of structural jamming.

[0019] 5. The truss of the self-propelled sprinkler has the water outlet end of the water pipe extending outward from the bottom of the winding wheel and passing through the tops of the first guide wheel and the second guide wheel. Combined with the water pipe fitting into the grooves in the middle of the first guide wheel and the second guide wheel, as the water pipe is driven to move and wind up, it can drive the first guide wheel and the second guide wheel to roll. Using rolling friction to reduce the friction force, guiding the water pipe, making the water pipe move smoothly and not easy to get stuck.

[0020] 6. The truss of the self-propelled sprinkler uses the water pipe to pass through the center of the conical cleaning hopper. As the water pipe continues to move, the conical cleaning hopper can scrape off the debris attached to the surface of the water pipe, thus cleaning the debris on the surface of the water pipe.

[0021] VII. For the truss of the self-propelled sprinkler, by utilizing the driving force of the circular push piece on the connecting teeth, the connecting teeth drive the conical cleaning bucket to slide. As the driving force of the circular push piece on the connecting teeth disappears and under the elastic force of the return spring, the connecting teeth drive the conical cleaning bucket to move in the reverse direction. Thus, through the reciprocating movement of the conical cleaning bucket, the sundries on the surface of the water pipe can be scraped multiple times.

[0022] VIII. For the truss of the self-propelled sprinkler, by utilizing the telescopic end of the electric telescopic rod to pull the pressing connecting rod, the outer circumferential surface of the pressing roller is attached to the surface of the water pipe, so that the water pipe can be rolled and pressed. Therefore, when the winding wheel winds and lowers the water pipe, the water pipe in the middle of the winding wheel always remains in a tight state and will not be disordered. Moreover, by using the elastic piece to elastically support the pressing roller, the water pipe is elastically pressed, which is not easy to damage the water pipe and plays a protective role.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0026] The first embodiment is as Figures 1 to 5 shown, the present invention provides a technical solution: A self-propelled sprinkler truss, comprising: A vehicle frame 1, and a winding wheel 2 installed on the top of the vehicle frame 1. Wheels 3 are installed at the bottom of the vehicle frame 1, and a water pipe 4 is wound on the surface of the winding wheel 2; A traveling mechanism 5, which is used to irrigate crops and move by itself. The traveling mechanism 5 is installed at the end of the surface of the vehicle frame 1; Among them, the traveling mechanism 5 includes a truss main body 51, a driving wheel 52 and a auxiliary wheel 53. The truss main body 51 is installed at the end of the surface of the vehicle frame 1. The driving wheel 52 and the auxiliary wheel 53 are installed at the bottom of the truss main body 51. A transmission 54 is fixedly installed at one end of the truss main body 51 away from the vehicle frame 1. A power source 55 is installed at the top of the surface of the transmission 54. A mud cleaning plate 56 is fixedly installed at the side of the surface of the truss main body 51. An arc-shaped gradient plate 57 is fixedly installed at the top of the inner side of the truss main body 51. An irrigation component 58 is installed at the middle of the top of the truss main body 51. By the rolling of the wheels 3, the vehicle frame 1 is driven to move, so that the vehicle frame 1 can be moved to a designated position in the farmland, and the pin shaft between the truss main body 51 and the vehicle frame 1 is removed, so that the truss main body 51 is separated from the vehicle frame 1. Under the support of the driving wheel 52 and the auxiliary wheel 53, the truss main body 51 stably supports the irrigation component 58, and the staff turns on the power source 55 to work. Using the driving force exerted by the power source 55 and the transmission of the driving force by the transmission 54, the driving wheel 52 rolls, and in combination with the rolling connection of the auxiliary wheel 53, the truss main body 51 drives the irrigation component 58 to move by itself without the traction of a traction device, and the crops are not easily crushed by the traction device; The output shaft of the power source 55 and the driving wheel 52 are installed through transmission by the transmission 54. The driving wheel 52 and the auxiliary wheel 53 are evenly distributed at the bottom of the truss main body 51. The mud cleaning plate 56 is installed directly above the driving wheel 52.

[0027] The irrigation assembly 58 includes a cylinder 581 and a cylinder 582. The cylinder 581 is hinged at the middle of the top of the truss body 51, and the cylinder 582 is hinged at the side of the top of the truss body 51. A connecting water channel 583 is rotatably installed inside the cylinder 582. A water spray head 584 is communicated with the top of the connecting water channel 583. A force-receiving tooth 585 is fixedly connected to the bottom of the outer circumferential surface of the connecting water channel 583. A torsion spring 586 is fixedly connected between the surface of the force-receiving tooth 585 and the bottom of the cylinder 582. A rotating connector 587 is installed between the bottom end of the connecting water channel 583 and the water outlet of the water pipe 4. By using the water pipe 4 to communicate with the connecting water channel 583, and during the conveyance of water by the water pipe 4, the water enters the inside of the connecting water channel 583 under the action of water pressure and is sprayed from the water spray head 584 towards the position of the crops to irrigate the crops.

[0028] Both the cylinder 582 and the connecting water channel 583 are vertically installed, and the connecting water channel 583 passes through the center of the cylinder 582. The water spray head 584, the connecting water channel 583 and the water pipe 4 are communicated. The staff starts the cylinder 581 to work. By using the elongation of the telescopic end of the cylinder 581, a pulling force can be applied to the cylinder 582. The cylinder 582 will drive the connecting water channel 583 to rotate counterclockwise to adjust the angle. Then, the water spray head 584 can be driven to rotate together by the connecting water channel 583, so that the water spray port of the water spray head 584 sprays water obliquely upward, making the water sprayed by the water spray head 584 farther, extending the spraying distance of the water spray head 584 for the water, and effectively irrigating the crops.

[0029] As the cylinder 582 is pulled by the telescopic end of the cylinder 581 and the connecting water channel 583 is driven to rotate counterclockwise, the force-receiving tooth 585 will be driven to move together by the connecting water channel 583. Combining with the contact between the roller at the end of the force-receiving tooth 585 and the arc-shaped gradient surface at the side of the arc-shaped gradient plate 57, the arc-shaped gradient plate 57 applies an outward pushing force to the force-receiving tooth 585, enabling the connecting water channel 583 to rotate along the central axis of the cylinder 582. The torsion spring 586 undergoes elastic deformation under the torque force, and the water spray head 584 is driven to rotate together, increasing the spraying range of the water spray head 584, making the irrigation range for the crops wider. And by using the connection between the water outlet of the water pipe 4 and the connecting water channel 583 through the rotating connector 587, the connecting water channel 583 drives the water spray head 584 to rotate smoothly and adjust the angle smoothly.

[0030] The cylinder 581 is installed obliquely, and the telescopic end of the cylinder 581 is hinged to the outer circumferential surface of the cylinder 582. The bottom of the connecting water channel 583 passes through the center of the torsion spring 586.

[0031] Second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 7 as shown: A guiding mechanism 6 is installed at the side inside the vehicle frame 1. The guiding mechanism 6 includes a round rod support frame 61. Both ends of the round rod support frame 61 are fixedly installed on the inner side surface of the vehicle frame 1 by screws. A first guide wheel 62 is rotatably installed on one side of the top of the round rod support frame 61, and a second guide wheel 63 is rotatably installed on the top of the round rod support frame 61 and away from the first guide wheel 62. One end of the water pipe 4 extending outside the winding wheel 2 passes through the tops of the first guide wheel 62 and the second guide wheel 63. Circular push pieces 64 are fixedly connected to both sides of the outer circumferential surface of the second guide wheel 63. A cleaning assembly 65 is installed at the middle of the top of the round rod support frame 61. The water outlet end of the water pipe 4 extends outward from the bottom of the winding wheel 2 and passes through the tops of the first guide wheel 62 and the second guide wheel 63. Combining with the water pipe 4 fitting into the grooves in the middle of the first guide wheel 62 and the second guide wheel 63, as the water pipe 4 is driven to move out and retract, the first guide wheel 62 and the second guide wheel 63 can be driven to roll, guiding the water pipe 4 and making the movement of the water pipe 4 smooth.

[0032] The first guide wheel 62 and the second guide wheel 63 are installed at the same height. The surface of the water pipe 4 fits into the grooves in the middle of the first guide wheel 62 and the second guide wheel 63. The water pipe 4 passes through the center of the conical cleaning hopper 654. As the water pipe 4 continuously moves, the sundries attached to the surface of the water pipe 4 can be scraped off by the conical cleaning hopper 654, cleaning the sundries on the surface of the water pipe 4.

[0033] The cleaning assembly 65 includes a connecting guide rod 651. The connecting guide rod 651 is fixedly connected to the top of the round rod support frame 61. A connecting tooth 652 is slidably installed on the surface of the connecting guide rod 651. A return spring 653 is fixedly connected between the surface of the connecting tooth 652 and the surface of the round rod support frame 61. A conical cleaning hopper 654 is fixedly connected to the top of the connecting tooth 652. The water pipe 4 passes through the center of the conical cleaning hopper 654. By the rolling of the second guide wheel 63, the circular push piece 64 can be driven to rotate together. Using the edge of the circular push piece 64 to contact the surface of the connecting tooth 652, the connecting tooth 652 is pushed by the circular push piece 64. Under the guiding action of the connecting guide rod 651, the connecting tooth 652 drives the conical cleaning hopper 654 to slide, and the return spring 653 is compressed. As the circular push piece 64 continuously rotates, the circular push piece 64 is separated from the connecting tooth 652, the pushing force received by the connecting tooth 652 disappears, and under the elastic force of the return spring 653, the connecting tooth 652 drives the conical cleaning hopper 654 to move in the reverse direction. Thus, the conical cleaning hopper 654 reciprocates to scrape the sundries on the surface of the water pipe 4 multiple times.

[0034] The connecting guide rod 651 passes through the center of the return spring 653. The connecting teeth 652 are installed obliquely. There are two connecting teeth 652, and the two connecting teeth 652 are symmetrically installed along the central axis in the middle of the conical cleaning hopper 654.

[0035] Third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 8 as shown in: At the top of the vehicle frame 1 and at one end far from the truss main body 51, an auxiliary mechanism 7 is installed. The auxiliary mechanism 7 includes an electric telescopic rod 71 and a pressing link 72. The bottom of the electric telescopic rod 71 is hinged to the side of the inner surface of the vehicle frame 1. The bottom end of the pressing link 72 is hinged to the top of the vehicle frame 1 and at one end far from the truss main body 51. The telescopic end of the electric telescopic rod 71 is hinged to the surface of the pressing link 72. At the top of the pressing link 72, an elastic sheet 73 is fixedly installed. At one end of the elastic sheet 73 far from the top of the pressing link 72, a pressing roller 74 is rotatably installed. The outer circumferential surface of the pressing roller 74 is attached to the surface of the water pipe 4. When the staff turns on the electric telescopic rod 71 to work, by using the contraction of the telescopic end of the electric telescopic rod 71, a pulling force can be applied to the pressing link 72, and then the elastic sheet 73 and the pressing roller 74 can be driven by the pressing link 72 to rotate counterclockwise to adjust the angle, so that the outer circumferential surface of the pressing roller 74 is attached to the surface of the water pipe 4, and the water pipe 4 can be rolled and pressed, so that when the winding wheel 2 winds and unwinds the water pipe 4, there will be no disorder; And the elastic sheet 73 is used to elastically support the pressing roller 74, so that the water pipe 4 is elastically pressed and is not easily damaged.

[0036] The electric telescopic rod 71 and the pressing link 72 are both installed obliquely. There are two pressing links 72, and the two pressing links 72 are symmetrically installed along the pressing roller 74. The elastic sheet 73 is arc-shaped.

[0037] When in use, first, by rolling the wheels 3, the vehicle frame 1 is driven to move, and the vehicle frame 1 can be moved to the designated position in the farmland. Then, the pin shaft between the truss main body 51 and the vehicle frame 1 is removed, so that the truss main body 51 is separated from the vehicle frame 1. Under the support of the driving wheel 52 and the auxiliary wheel 53, the truss main body 51 stably supports the irrigation assembly 58; And when the staff turns on the electric telescopic rod 71 to work, by using the contraction of the telescopic end of the electric telescopic rod 71, a pulling force can be applied to the pressing link 72, and then the elastic sheet 73 and the pressing roller 74 can be driven by the pressing link 72 to rotate counterclockwise to adjust the angle, so that the outer circumferential surface of the pressing roller 74 is attached to the surface of the water pipe 4, and the water pipe 4 can be rolled and pressed, so that when the winding wheel 2 winds and unwinds the water pipe 4, there will be no disorder; Meanwhile, the staff turns on the power source 55 to work. By using the driving force exerted by the power source 55 and the transmission of the driving force by the transmission 54, the driving wheel 52 rolls. Combined with the rolling connection of the auxiliary wheel 53, the truss main body 51 drives the irrigation assembly 58 to move by itself without the traction of a traction device, and the crops are not easily crushed by the traction device. Moreover, as the truss main body 51 moves as a whole, the water pipe 4 is pulled to move. The water outlet end of the water pipe 4 extends outward from the bottom of the winding wheel 2, passes through the top of the first guide wheel 62 and the top of the second guide wheel 63. Combined with the grooves in the middle of the water pipe 4 and the first guide wheel 62 and the grooves in the middle of the second guide wheel 63 being fitted, as the water pipe 4 is driven to move and wind up, the first guide wheel 62 and the second guide wheel 63 can be driven to roll to guide the water pipe 4, making the movement of the water pipe 4 smooth. And by using the connection between the water pipe 4 and the connecting water channel 583 and the conveyance of water by the water pipe 4, the water enters the interior of the connecting water channel 583 under the action of water pressure and is sprayed from the sprinkler head 584 to the position of the crops for irrigation of the crops. Meanwhile, the staff turns on the cylinder 581 to work. By using the elongation of the telescopic end of the cylinder 581, a pulling force can be applied to the cylinder 582. The cylinder 582 will drive the connecting water channel 583 to rotate counterclockwise to adjust the angle. Then, the sprinkler head 584 can be driven to rotate together by the connecting water channel 583, so that the water outlet of the sprinkler head 584 sprays water obliquely upward, making the water sprayed by the sprinkler head 584 farther, extending the spraying distance of the sprinkler head 584 for water, and effectively irrigating the crops. As the cylinder 582 is pulled by the telescopic end of the cylinder 581 and the connecting water channel 583 is driven to rotate counterclockwise by the telescopic end of the cylinder 581, the force-bearing tooth 585 will be driven to move together by the connecting water channel 583. Combined with the contact between the roller at the end of the force-bearing tooth 585 and the arc-shaped gradient surface on the side of the arc-shaped gradient plate 57, the arc-shaped gradient plate 57 exerts an outward pushing force on the force-bearing tooth 585, so that the connecting water channel 583 rotates along the central axis of the cylinder 582. The torque spring 586 undergoes elastic deformation under the torque force, and the sprinkler head 584 is driven to rotate together, increasing the spraying range of the sprinkler head 584, making the irrigation range of the crops wide. And by using the connection between the water outlet of the water pipe 4 and the connecting water channel 583 through the rotating connector 587, the connecting water channel 583 drives the sprinkler head 584 to rotate smoothly and adjust the angle smoothly. Moreover, by using the water pipe 4 passing through the center of the conical cleaning hopper 654, along with the continuous movement of the water pipe 4, the sundries attached to the surface of the water pipe 4 can be scraped off by the conical cleaning hopper 654 to clean the sundries on the surface of the water pipe 4. By the rolling of the second guide wheel 63, the circular push piece 64 can be driven to rotate together. By using the contact between the edge of the circular push piece 64 and the surface of the connecting tooth 652, the connecting tooth 652 is subjected to the driving force of the circular push piece 64. Under the guiding action of the connecting guide rod 651, the connecting tooth 652 drives the conical cleaning hopper 654 to slide, and the return spring 653 is compressed. As the circular push piece 64 continues to rotate, the circular push piece 64 is separated from the connecting tooth 652, the driving force received by the connecting tooth 652 disappears, and under the elastic force of the return spring 653, the connecting tooth 652 drives the conical cleaning hopper 654 to move in the reverse direction. Thus, through the reciprocating movement of the conical cleaning hopper 654, the sundries on the surface of the water pipe 4 can be scraped multiple times. After the irrigation is completed, by the rolling of the driving wheel 52, the truss main body 51 can be driven to move towards the side close to the vehicle frame 1, and the truss main body 51 is fixed to the vehicle frame 1 through the pin shaft. Then, by the rolling of the wheels 3 again, the whole device can be driven away.
