Description

Technical Field

[0001] This utility model belongs to the field of rice field irrigation technology, and particularly relates to rice field irrigation devices. Background Technology

[0002] Rice is one of the most important food crops for humankind and is widely cultivated in southern regions. Due to its unique growth characteristics, rice requires a large amount of water in the early stages of growth to achieve rapid growth, which means that rice paddies need to be irrigated in the early stages of rice cultivation.

[0003] Current mainstream rice irrigation equipment generally adopts a combined structure of traditional water pumps and connecting pipes, which has significant structural defects in actual operation. The core problem lies in the lack of a filtration system, allowing algae and solid impurities carried by the water during irrigation to easily enter the pump body through the inlet. This intrusion of impurities causes two operational failures: firstly, the high-speed rotating impeller assembly experiences an entanglement effect when it comes into contact with fibrous aquatic plants, leading to drive shaft jamming and abnormal bearing wear; secondly, quartz gravel creates turbulent friction within the pipes, causing honeycomb-like erosion damage on the surface of the flow components. More seriously, the mixed fluid that is not effectively intercepted will clog the sprinkler irrigation device at the end of the delivery process, causing a decrease in the cross-sectional area of ​​the nozzle flow channel, ultimately resulting in a significant density gradient and coverage blind spots in the irrigation water curtain.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 3 This utility model discloses a paddy field irrigation device, comprising: a cabinet 1, a walking part on the bottom surface of the cabinet 1, a telescopic part on the top surface of the cabinet 1, a water storage chamber 14 inside the cabinet 1, one end of the water storage chamber 14 being connected to a pumping component, the other end of the pumping component being connected to a filter component, and a spraying component being connected to the water storage chamber 14, the spraying component being mounted on the telescopic part; the filter component includes a connecting box 4 connected to the pumping component, a first filter screen 5 being circumferentially fixed inside the connecting box 4, one end of a hollow tube 6 being connected to the connecting box 4, and the first filter screen 5 being located between the hollow tube 6 and the pumping component;

[0031] One end of the first flexible tube 7 is connected to the outer wall of the hollow tube 6, and the other end of the first flexible tube 7 is provided with a second filter screen 9. The mesh number of the first filter screen 5 is greater than that of the second filter screen 9.

[0032] The first flexible hose 7 is placed in the water, and the pumping assembly is activated. The water undergoes preliminary filtration through the second filter screen 9 and then flows through the first flexible hose 7 and the hollow tube 6 into the connecting box 4. The first filter screen 5 in the connecting box 4 performs further filtration before the water is pumped into the storage chamber 14. The traveling mechanism moves the cabinet 1 through the paddy field. Once it reaches the designated location, the telescopic mechanism is activated to deploy the sprinkler assembly, which irrigates the rice. The double filtration of algae and solid impurities ensures clean water is stored in the storage chamber 14, preventing clogging of the irrigation device and a reduction in the nozzle flow area.

[0033] The design is further optimized by setting the lower part of the connecting box 4 as an inverted frustum shape, and the bottom end of the connecting box 4 is connected to the drain pipe 12, which is equipped with a valve 13.

[0034] When algae and solid impurities carried by the water pass through the connecting box 4, they will be deposited at the bottom of the connecting box 4 and discharged by the control valve 13.

[0035] In a further optimized design, the hollow tube 6 is rotatably connected to the connecting box 4, and a section of the hollow tube 6 away from the connecting box 4 extends out of the cabinet 1 and is fixedly installed with a handle 10. The hollow tube 6 is rotatably connected to the cabinet 1, and the first flexible hose 7 is wrapped around the outer wall of the hollow tube 6.

[0036] When pumping water, turn the handle 10 to release the first hose 7 wrapped around the hollow tube 6 downwards. The first hose 7 passes through the reserved opening at the bottom of the cabinet 1 and enters the water body. The water body passes through the first hose 7 and the hollow tube 6 and enters the connecting box 4.

[0037] Further optimization of the scheme: the water pumping assembly includes a first water pump 2, which is fixedly installed on the inner wall of the cabinet 1. The input end of the first water pump 2 is connected to one end of the water pumping pipe 3, and the other end of the water pumping pipe 3 is connected to the top of the connecting box 4. The output end of the first water pump 2 is connected to one end of the first drain pipe 11, and the other end of the first drain pipe 11 is connected to the water storage chamber 14.

[0038] The first water pump 2 draws water out of the connecting box 4 and delivers it to the water storage chamber 14 through the first drain pipe 11.

[0039] The design is further optimized so that the telescopic part includes a support 18 fixedly installed on the top surface of the cabinet 1, and a motor 19 is fixedly installed on the support 18.

[0040] One end of a first connecting rod 20 and one end of a second connecting rod 21 are rotatably connected to the support 18 via two first short shafts. The other ends of the first connecting rod 20 and the second connecting rod 21 are rotatably connected to the first connecting member 23 via two second short shafts. The first connecting rod 20 and the second connecting rod 21 are arranged in parallel. The first connecting rod 20 or the second connecting rod 21 is fixedly connected to the output shaft of the motor 19. The output shaft of the motor 19 is coaxial with the first short shaft.

[0041] One end of a third connecting rod 24 and a fourth connecting rod 25 are rotatably connected to the first connecting member 23 via two third short shafts. The other ends of the third connecting rod 24 and the fourth connecting rod 25 are rotatably connected to the second connecting member 28 via two fourth short shafts. The third connecting rod 24 and the fourth connecting rod 25 are arranged in parallel. A second gear 26 is fixedly connected to one end of the third connecting rod 24 or the fourth connecting rod 25. The second gear 26 is coaxially arranged with one of the third short shafts. A first gear 22 is fixedly connected to one end of the first connecting rod 20 or the second connecting rod 21. The second gear 26 is coaxially arranged with one of the second short shafts. The second gear 26 meshes with the first gear 22.

[0042] The second connecting member 28 is rotatably connected to one end of the fifth connecting rod 29 via the fifth short shaft. The end of the fifth connecting rod 29 is fixedly connected to the fourth gear 30, which is coaxial with the fifth short shaft. The end of the third connecting rod 24 or the fourth connecting rod 25 away from the first connecting member 23 is fixedly connected to the third gear 27, which is coaxial with one of the fourth short shafts and meshes with the fourth gear 30.

[0043] Motor 19 drives one end of the first link 20 or the second link 21 to rotate. The first gear 22 and the second gear 26 at the other end of the second link 21 mesh, thereby driving the fourth link 25 to rotate. When the fourth link 25 rotates, the fourth gear 30, which meshes with the third gear 27 at the other end, rotates, thereby driving the fifth link 29 to rotate.

[0044] Support 18, motor 19, first link 20, and second link 21 form a planar four-bar linkage through first connector 23, and third link 24 and fourth link 25 form a planar four-bar linkage through first connector 23 and second connector 28.

[0045] The solution is further optimized. The spray assembly includes several fixing rings 31 fixedly connected to the first connecting rod 20, the third connecting rod 24 and the fifth connecting rod 29. A second drain pipe 16 is inserted inside the several fixing rings 31. Several nozzles 17 are provided on the pipe wall of the second drain pipe 16.

[0046] One end of the second drain pipe 16 extends into the water storage chamber 14 and is connected to the output end of the second water pump 15.

[0047] Multiple nozzles are installed on the second drain pipe 16, and the nozzles are arranged at equal intervals along the length of the second drain pipe 16. As the first link 20, the third link 24 and the fifth link 29 are deployed, the spray coverage area can be increased.

[0048] The design is further optimized so that the walking part includes a base 32, and both sides of the base 32 are connected to the track 33 for transmission. The top surface of the base 32 is fixedly connected to the bottom surface of the cabinet 1.

[0049] A drive motor is installed inside the base 32. The output shaft of the drive motor extends out of the base 32. A drive wheel is coaxially fixed to the output shaft of the drive motor. Multiple support wheels are also provided on both sides of the base 32. The multiple support wheels are evenly distributed on both sides of the base. The track 33 is wrapped around the drive wheel and the multiple support wheels. A tensioning device is also provided at the front end of the base 32. By adjusting the tension of the track, the tight engagement between the track and the drive wheel is ensured, and unnecessary energy loss is reduced.

[0050] The scheme is further optimized by fixing a counterweight 8 on the first flexible tube 7. The counterweight 8 is located at the end away from the hollow tube 6.

[0051] The counterweight 8 provides counterweight for the first hose 7, making it easier for the first hose 7 to sink into the water.

[0052] The design is further optimized by adding an inspection door 34 to one side of the cabinet 1, which is correspondingly set with the connection box 4.

[0053] An inspection opening is provided on the cabinet 1, and the inspection door 34 is connected to the cabinet 1 by a hinge. The accumulation of debris in the connecting box 4 can be checked through the inspection door 34.

[0054] During the pumping process, the first hose 7 with the counterweight 8 is inserted into the water body by manually turning the handle 10, and the first water pump 2 is started. The water body passes through the second filter screen 9, the first hose 7, the hollow tube 6, and the first filter screen 5 in the connecting box 4, and then enters the water storage chamber 14 for storage.

[0055] In use, the device moves across the paddy field via the tracks 33 of the walking unit. The track design increases the device's mobility and stability in muddy fields. The operator moves the cabinet 1 to the designated location according to the layout of the paddy field and irrigation needs. Activating the motor 19 of the telescopic unit extends the second drain pipe 16, and activating the second water pump 15 located in the water storage chamber 14 causes the stored water to flow through the second drain pipe 16 and be sprayed from the nozzle 17 to irrigate the rice.
