Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and more particularly to a water-saving irrigation device for citrus. Background Technology

[0002] Crop farming is a major component of agriculture. It is a social production sector that utilizes the life functions of plants to obtain food, by-products, feed, and industrial raw materials through artificial cultivation. It includes the cultivation of various crops, trees, fruit trees, medicinal plants, and ornamental plants. Categories include food crops, cash crops, vegetable crops, green manure crops, forage crops, pasture grasses, and horticultural crops such as flowers.

[0003] Planting requires irrigation, and there are two existing irrigation methods: mechanical irrigation and manual irrigation. Mechanical irrigation mainly uses rotating sprinklers to spray water in a fan-shaped manner.

[0004] In the current citrus planting process, mechanical irrigation is mostly used. The method of sprinkling makes it difficult to determine the amount of water used for each irrigation, which easily leads to water waste. The land that needs irrigation does not receive sufficient water, so it is necessary to repeat the irrigation process multiple times. Also, the roots do not have direct contact with water, and very little water is absorbed from the top down to the roots. It also easily makes the walking path wet, resulting in a lot of water waste. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-saving irrigation device for citrus.

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

[0007] A water-saving irrigation device for citrus includes a trolley, a water tank fixed to one side of the top of the trolley, a base plate installed on the side of the top of the trolley away from the water tank, U-shaped frames at both ends of the top of the base plate, water pipes installed inside the U-shaped frames, a number of nozzles fixed at equal intervals on the outer wall of the water pipes, a water supply system for supplying water to the trolley, a swing mechanism for swinging the U-shaped frames installed on the base plate, and a stepper motor for operating the swing mechanism installed on the trolley.

[0008] The swing mechanism includes a second synchronous pulley, with first connecting rods coaxially fixed to both sides of the second synchronous pulley. A first turntable is fixed to the end of the first connecting rod away from the second synchronous pulley. First support rods are fixed to both ends of the top of the base plate. A swing plate is rotatably connected to the top of the first support rod. A guide rod is fixed to the top of the swing plate near the first turntable. The U-shaped frame is fixed to the swing plate away from the first turntable. A sliding sleeve is slidably fitted onto the outer wall of the guide rod. A top rod is fixed to the outer wall of the sliding sleeve. A hole for the top rod to pass through is opened on the first turntable, and the top rod has a portion that protrudes from the hole. A reinforcing bend is fixed to the top of the outer wall of the first support rod. A first fixing sleeve is fixed to the other end of the reinforcing bend. The first connecting rod passes through the first fixing sleeve. The outer wall of the first connecting rod... The fixed sleeve is equipped with limiting retaining rings near both ends of the first fixed sleeve. The stepper motor is fixed to the top of the vehicle plate. The output shaft of the stepper motor is fixed to the first synchronous pulley through a coupling. The first synchronous pulley is connected to the second synchronous pulley through the first synchronous belt. When the stepper motor is working, it directly drives the first synchronous pulley and the third synchronous pulley to rotate. The first synchronous pulley realizes the rotation of the second synchronous pulley through the first synchronous belt, thereby realizing the rotation of the first connecting rod. Since the first connecting rod passes through the second fixed sleeve and the first fixed sleeve, the second fixed sleeve and the first fixed sleeve form a support for the first connecting rod. The first connecting rod drives the first turntable to rotate. Under the action of the top rod, the sliding sleeve makes a circular motion, which drives the guide rod rotating on the first support rod synchronously. Finally, the U-shaped frame and the water pipe swing synchronously, so that the oscillating spray can be performed when the cart moves.

[0009] As a further embodiment of the present invention, the trolley includes a platform, with fixing blocks fixed at both ends of the platform near the water tank. A single handlebar is fixed to both fixing blocks. First mounting legs are fixed at both ends of the bottom of the platform near the handlebar. Each first mounting leg has a groove in which a roller is rotatably mounted. Two symmetrical second mounting legs are fixed at the bottom of the platform away from the first mounting legs. A caster wheel is fixed to the bottom of each second mounting leg. A second connecting rod is coaxially fixed between the two rollers. A hole is provided on each first mounting leg for the second connecting rod to pass through. A second gear with a centrally located hole is fixedly fitted onto the outer wall of the second connecting rod. The second gear meshes with a first gear. A fourth synchronous pulley is coaxially fixed to the first gear. Both the first gear and the fourth synchronous pulley have communicating holes, and a third connecting rod is fixedly inserted through the holes. The third connecting rod is rotatably positioned between the two first mounting legs. The third synchronous pulley is coaxially fixed to the first synchronous pulley. The third synchronous pulley is connected to the fourth synchronous pulley via a second synchronous belt. A stepper motor drives the third synchronous pulley to rotate, and the fourth synchronous pulley rotates under the action of the second synchronous belt. The first gear connected to it rotates synchronously. Since the second gear meshes with the first gear, the second gear rotates accordingly. The size of the second gear is smaller than that of the first gear, and the size of the fourth synchronous pulley is larger than that of the third synchronous pulley, thereby achieving a speed change effect. Under the action of the stepper motor, it helps the rotation of the roller and provides assistance to the trolley.

[0010] As a further embodiment of the present invention, a second support rod is fixed at both ends of the top of the base plate, a second fixing sleeve is fixed at the top of the second support rod, the first connecting rod passes through the second fixing sleeve, and the base plate is fixed to the top of the vehicle plate by bolts.

[0011] As a further embodiment of the present invention, the water supply system includes a water pump fixed to the top of the vehicle platform. The inlet of the water pump is connected to the outlet of the water tank through a pipe. A three-way connector is fixed to the outlet of the water pump. Corrugated hoses are fixed to the other two ports of the three-way connector. A rotary joint is fixed to the inlet of the water pipe. The rotary joint is fixed to the corresponding corrugated hose. A hole is opened on the outer wall of the U-shaped frame for the water supply pipe inlet port to pass through. When the water pump is working, it draws water from inside the water tank into the three-way connector. The water enters the water pipe through the three-way connector and the corrugated hose. Under the connection of the corrugated hose, the swinging water supply of the U-shaped frame is not affected.

[0012] As a further embodiment of the present invention, an adjustment mechanism is installed at the bottom of the U-shaped frame away from the water supply system. The adjustment mechanism includes a motor mounting plate fixed to the bottom of the U-shaped frame, a drive motor fixed to the outer wall of the motor mounting plate, and a second turntable fixed to the output shaft of the drive motor via a coupling. A guide head is fixed to the outer wall of the second turntable away from the center. A guide arm is coaxially fixed to the water pipe, and a hole for the shaft to pass through is provided on the U-shaped frame. A guide groove for the guide head to move is provided on the outer wall of the guide arm. An adjustment mechanism is provided, including a motor mounting plate, a drive motor, a guide arm, a guide groove, and a second turntable. By operating the drive motor, the second turntable rotates, and the guide head on the second turntable moves in the guide groove within the guide arm, forcing the guide arm to reciprocate. Since the water pipe is coaxially fixed to the guide arm, the water pipe can be oscillating and spraying. The spraying angle of the water pipe can also be locked, allowing the nozzle to be directed towards the roots of the citrus trees for irrigation, thus achieving a certain water-saving effect.

[0013] As a further embodiment of the present invention, a battery pack is fixed to the top of the vehicle platform, a control panel is fixed to the top of the water tank, a PLC controller is installed in the control panel, the PLC controller is electrically connected to the battery, and the PLC controller is electrically connected to the water pump, the drive motor and the stepper motor.

[0014] As a further embodiment of the present invention, the water tank is U-shaped, with a water inlet at the top and the water pump located in the U-shaped groove of the water tank.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention employs a trolley, water tank, water supply system, water pipes, nozzles, a second gear, and a first gear. As the trolley moves, it sprays the citrus trees planted on both sides. When the stepper motor operates, it rotates the first connecting rod, which in turn rotates the first turntable. Under the action of the push rod, the sliding sleeve performs a circular motion, ultimately achieving synchronous oscillation of the U-shaped frame and the water pipes. As the trolley moves, the stepper motor drives the third synchronous wheel to rotate. Because the second gear meshes with the first gear, it rotates accordingly, aiding the rotation of the rollers and providing assistance to the trolley. This effectively solves the problems raised in the background technology, enabling the trolley to move while simultaneously spraying the citrus trees on both sides of the path in a reciprocating oscillating motion. This avoids the waste and lack of targeting of existing widespread spraying methods, and allows for easy spraying on the path and in non-planting areas.

[0017] This invention features an adjustment mechanism that drives a motor to rotate a second turntable. A guide head on the second turntable moves within a guide groove in a guide arm, forcing the guide arm to reciprocate. Since the water pipe is coaxially fixed with the guide arm, the water pipe can be oscillating and spraying. The spraying angle of the water pipe can also be locked, allowing the nozzle to be directed towards the roots of the citrus trees for irrigation, thus achieving a certain water-saving effect.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-8 A water-saving irrigation device for citrus includes a trolley 1, a water tank 2 fixed on one side of the top of the trolley 1, a base plate 11 installed on the side of the top of the trolley 1 away from the water tank 2, a U-shaped frame 14 set at both ends of the top of the base plate 11, a water pipe 5 installed inside the U-shaped frame 14, a number of nozzles 6 fixed at equal intervals on the outer wall of the water pipe 5, a water supply system 4 for supplying water to the water pipe 5 installed on the trolley 1, a swing mechanism for swinging the U-shaped frame 14 installed on the base plate 11, and a stepper motor 7 for running the swing mechanism installed on the trolley 1.

[0030] The swing mechanism includes a second synchronous pulley 10, with first connecting rods 17 coaxially fixed on both sides of the second synchronous pulley 10. A first turntable 18 is fixed to the end of the first connecting rod 17 away from the second synchronous pulley 10. First support rods 12 are fixed to both ends of the top of the base plate 11. A swing plate 13 is rotatably connected to the top of the first support rod 12. A guide rod 19 is fixed to the top of the swing plate 13 near the first turntable 18. A U-shaped frame 14 is fixed to the swing plate 13 away from the first turntable 18. A sliding sleeve 20 is slidably fitted onto the outer wall of the guide rod 19. A top rod 21 is fixed to the outer wall of the sliding sleeve 20. A hole for the top rod 21 to pass through is provided on the first turntable 18, and the top rod 21 has a portion extending out of the hole. A reinforcing bent tube 15 is fixed to the top of the outer wall of the first support rod 12. A first fixing sleeve 16 is fixed to the other end of the reinforcing bent tube 15. The first connecting rod 17 passes through the first fixing sleeve 16. A first fixing sleeve 16 is fixed to the outer wall of the first connecting rod 17 near the first fixing sleeve 18. The first fixed sleeve 16 has limiting rings 33 at both ends. The stepper motor 7 is fixed to the top of the vehicle plate 101. The output shaft of the stepper motor 7 is fixed to the first synchronous pulley 8 through a coupling. The first synchronous pulley 8 is connected to the second synchronous pulley 10 through the first synchronous belt 9. When the stepper motor 7 is working, it directly drives the first synchronous pulley 8 and the third synchronous pulley 24 to rotate. The first synchronous pulley 8 realizes the rotation of the second synchronous pulley 10 through the first synchronous belt 9, thereby realizing the rotation of the first connecting rod 17. Since the first connecting rod 17 passes through the second fixed sleeve 22 and the first fixed sleeve 16, the second fixed sleeve 22 and the first fixed sleeve 16 form a support for the first connecting rod 17. The first connecting rod 17 drives the first turntable 18 to rotate. Under the action of the top rod 21, the sliding sleeve 20 makes a circular motion, which drives the guide rod 19 rotating on the first support rod 12 synchronously. Finally, the U-shaped frame 14 and the water pipe 5 swing synchronously, and can swing and spray when the cart 1 moves.

[0031] In this embodiment, the trolley 1 includes a platform 101. Fixing blocks 107 are fixed at both ends of the platform 101 near the water tank 2. A handlebar 102 is fixed to both fixing blocks 107. First mounting legs 103 are fixed at both ends of the bottom of the platform 101 near the handlebar 102. A groove is formed in the first mounting leg 103, and a roller 104 is rotatably mounted in the groove. Two symmetrical second mounting legs 105 are fixed at the bottom of the platform 101 away from the first mounting legs 103. A caster wheel 106 is fixed to the bottom of each second mounting leg 105. A second connecting rod 29 is coaxially fixed between the two rollers 104. A hole is formed on the first mounting leg 103 for the second connecting rod 29 to pass through. A second gear 28 with a central opening is fixedly fitted onto the outer wall of the second connecting rod 29. The second gear 28 meshes with a first gear 27, which is coaxial. A fourth synchronous pulley 26 is fixedly provided. Both the first gear 27 and the fourth synchronous pulley 26 have communicating holes, and a third connecting rod 30 is fixedly inserted through the holes. The third connecting rod 30 is rotatably positioned between the two first mounting legs 103. The first synchronous pulley 8 is coaxially fixed with a third synchronous pulley 24. The third synchronous pulley 24 is connected to the fourth synchronous pulley 26 through a second synchronous belt 25. The stepper motor 7 drives the third synchronous pulley 24 to rotate. Under the action of the second synchronous belt 25, the fourth synchronous pulley 26 rotates. The first gear 27 connected to it rotates synchronously. Since the second gear 28 meshes with the first gear 27, the second gear 28 rotates accordingly. The size of the second gear 28 is smaller than that of the first gear 27, and the size of the fourth synchronous pulley 26 is larger than that of the third synchronous pulley 24, thereby achieving a speed change effect. Under the action of the stepper motor 7, it helps the roller 104 to rotate, which provides assistance to the trolley 1.

[0032] In this embodiment, a second support rod 23 is fixed at both ends of the top of the base plate 11, and a second fixing sleeve 22 is fixed at the top of the second support rod 23. The first connecting rod 17 passes through the second fixing sleeve 22, and the base plate 11 is fixed to the top of the vehicle plate 101 by bolts.

[0033] In this embodiment, the water supply system 4 includes a water pump 401 fixed to the top of the vehicle platform 101. The inlet of the water pump 401 is connected to the outlet of the water tank 2 through a pipe. A three-way connector 402 is fixed to the outlet of the water pump 401. Corrugated hoses 403 are fixed to the other two ports of the three-way connector 402. A rotary joint 404 is fixed to the inlet of the water pipe 5. The rotary joint 404 is fixed to the corresponding corrugated hose 403. A hole is opened on the outer wall of the U-shaped frame 14 for the water supply pipe 5 to pass through. When the water pump 401 is working, it draws water from inside the water tank 2 into the three-way connector 402. The water enters the water pipe 5 through the three-way connector 402 and the corrugated hose 403. Under the connection of the corrugated hose 403, the swinging water supply of the U-shaped frame 14 will not be affected.

[0034] In this embodiment, an adjustment mechanism 32 is installed at the bottom of the U-shaped frame 14, away from the water supply system 4. The adjustment mechanism 32 includes a motor mounting plate 320 fixed to the bottom of the U-shaped frame 14. A drive motor 321 is fixed to the outer wall of the motor mounting plate 320. The output shaft of the drive motor 321 is fixed to a second turntable 324 via a coupling. A guide head 325 is fixed to the outer wall of the second turntable 324, away from the center. A guide arm 322 is coaxially fixed to the water pipe 5. A hole for the shaft to pass through is provided on the U-shaped frame 14. A guide groove 323 for the guide head 325 to move is provided on the outer wall of the guide arm 322. An adjustment mechanism 32 is provided, which includes a motor mounting plate 320, a drive motor 321, a guide arm 322, a guide groove 323, and a second turntable 324. The second turntable 324 is rotated by the operation of the drive motor 321. The guide head 325 located on the second turntable 324 moves in the guide groove 323 in the guide arm 322, forcing the guide arm 322 to reciprocate. Since the water pipe 5 is coaxially fixed with the guide arm 322, the water pipe 5 can be oscillating and spraying. The spraying angle of the water pipe 5 can also be locked, so that the nozzle 6 can be directed to irrigate the roots of the citrus, which has a certain water-saving effect.

[0035] In this embodiment, a battery pack 31 is fixed to the top of the vehicle plate 101, and a control panel 3 is fixed to the top of the water tank 2. A PLC controller is installed in the control panel 3. The PLC controller is electrically connected to the battery and is also electrically connected to the water pump 401, the drive motor 321, and the stepper motor 7.

[0036] In this embodiment, the water tank 2 is U-shaped, with a water inlet at the top and the water pump 401 located in the U-shaped groove of the water tank 2.

[0037] Working principle: The system includes a trolley 1, water tank 2, water supply system 4, water pipe 5, nozzle 6, second gear 28, and first gear 27. When in use, water is injected into the water tank 2 through the inlet, pushing the trolley 1 onto the orchard path. The angle of the water pipe 5 and nozzle 6 is adjusted via the adjustment mechanism 32. This starts the water pump 401 and stepper motor 7. The water pump 401 draws water from the water tank 2 into the three-way connector 402. The water then flows through the three-way connector 402 and the corrugated flexible... Pipe 403 enters water pipe 5, allowing spraying from nozzle 6. The two symmetrical nozzles 6 spray the citrus trees planted on both sides as the cart 1 moves. Simultaneously, when stepper motor 7 operates, it directly drives the first synchronous pulley 8 and the third synchronous pulley 24 to rotate. The first synchronous pulley 8, via the first synchronous belt 9, drives the second synchronous pulley 10 to rotate, thereby rotating the first connecting rod 17. Since the first connecting rod 17 passes through the second fixed sleeve 22 and the first fixed sleeve 16, the second fixed sleeve 22 and the first fixed sleeve 16 form a support to the first connecting rod 17. Supported by 7, the first connecting rod 17 drives the first turntable 18 to rotate. Under the action of the top rod 21, the sliding sleeve 20 makes a circular motion, which drives the guide rod 19 rotating on the first support rod 12 synchronously. Finally, the U-shaped frame 14 and the water pipe 5 swing synchronously. When the cart 1 moves, it can swing and spray. At the same time, the stepper motor 7 drives the third synchronous wheel 24 to rotate. Under the action of the second synchronous belt 25, the fourth synchronous wheel 26 rotates. The first gear 27 connected to it rotates synchronously. Since the second gear 28 meshes with the first gear 27, the second gear 28 rotates accordingly. The size of the second gear 28 is smaller than that of the first gear 27, and the size of the fourth synchronous wheel 26 is larger than that of the third synchronous wheel 24, so as to achieve a speed change effect. Under the action of the stepper motor 7, it helps the roller 104 to rotate, which has an assisting effect on the cart 1. It effectively solves the problems raised in the background technology, and realizes the reciprocating swing spraying of citrus on both sides of the path while assisting the movement of the cart 1. It avoids the waste and lack of targeting of the existing extensive spraying and is easy to spray on the path and non-planting areas.
