Description

Technical Field

[0001] This invention relates to the field of irrigation technology, and in particular to an automated irrigation device for paddy fields and its usage method. Background Technology

[0002] my country is a major agricultural country, cultivating a large number of crops. In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply crops with sufficient water. Under natural conditions, insufficient rainfall or uneven distribution often fails to meet the water requirements of crops. Therefore, artificial irrigation is necessary to supplement the lack of natural rainfall, which plays an important role in crop yield. With the continuous development of science and technology, irrigation methods have become more diverse, from the most primitive water carrying to water pumping for flood irrigation, to modern mechanized irrigation. Among them, drip irrigation is the most resource-saving method.

[0003] A search revealed that utility model CN217184193U discloses a water-saving and environmentally friendly automated irrigation device, comprising a base plate. An irrigation assembly is fixedly connected to the front upper part of the base plate. Telescopic rods are fixedly connected to the four corners of the lower part of the base plate. Support plates are fixedly connected to the lower ends of two longitudinal telescopic rods. Three crossbars are fixedly connected between the two support plates. Two rotating wheels are fixedly connected to the lower ends of the two support plates. A water tank and a second water pump are fixedly connected to the rear upper part of the base plate, with the second water pump located on the right side of the water tank. A tank cover is snapped onto the upper end of the water tank, and a first water pump is fixedly connected to the upper end of the tank cover. This utility model's water-saving and environmentally friendly automated irrigation device, through the arrangement of the irrigation device and motor, achieves high irrigation efficiency, good irrigation effect, and high stability, making it suitable for use in water-saving and environmentally friendly automated irrigation systems.

[0004] The device also has the following disadvantages during use: it is manually pushed to move and then spray irrigation, but its water tank capacity is limited, and it needs to be stopped to add water during the movement. In addition, it also needs to be manually stirred when adding liquid fertilizer, which is not only inconvenient to use, but also consumes manpower. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as limited water tank capacity, the need to stop and add water during movement, and the need for manual stirring when adding liquid fertilizer, which are not only inconvenient to use but also labor-intensive. Therefore, this invention proposes an automated irrigation device for paddy fields and its usage method.

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

[0007] An automated irrigation device for paddy fields includes a water tank and a base plate located on the ground on one side of the water tank. The top of the water tank has an inlet for feeding. Multiple stirring spoons for stirring the liquid are rotatably installed inside the water tank. A first motor is fixed on the top of the water tank. The output end of the first motor is connected to the stirring spoons to provide power to the stirring spoons.

[0008] A water bucket is fixedly installed inside a water tank. A sliding plate is slidably installed inside the water bucket. Two third connecting pipes are fixedly installed through the bottom of the water tank. One end of each third connecting pipe extends into the water bucket. The sliding plate can move to squeeze the water in the water bucket into the third connecting pipe for irrigation.

[0009] The first connecting pipe is slidably disposed on the top of the base plate. Two second connecting pipes are fixedly disposed through the outer wall of the first connecting pipe. Multiple spray pipes are fixedly disposed through the bottom of the second connecting pipes. The first connecting pipe is connected to the two third connecting pipes through a fourth connecting pipe for guiding water so that water is sprayed toward the plants.

[0010] The second motor is mounted on the base plate. Its output end is connected to the first connecting pipe to drive the first connecting pipe to move. It is also connected to the sliding plate to drive the sliding plate to reciprocate and squeeze water.

[0011] The blocking mechanism, located inside the water tank, is used to seal the top of the water bucket to prevent unmixed water and fertilizer from flowing into the bucket.

[0012] In one possible design, two side plates are fixedly provided on the top of the base plate, and two rotating rollers are rotatably provided through the two side plates. The outer walls of the two rotating rollers are connected to the same transmission belt, and the two ends of the transmission belt are fixedly provided with the same sliding block. The first connecting pipe is fixedly provided on the sliding block, and the output end of the second motor is fixedly connected to one of the rotating rollers.

[0013] In one possible design, grooves are provided on both sides of the sliding block, and guide bars are slidably arranged in the grooves. The guide bars are fixed on the inner side of the side plate and are used to support and guide the sliding block.

[0014] In one possible design, a reciprocating screw is rotatably mounted on one side of the water tank and located inside the water bucket. The sliding plate is threaded onto the reciprocating screw. The adjacent ends of the reciprocating screw and the rotating roller are fixedly fitted with meshing bevel gears. A one-way valve is provided on the third connecting pipe to prevent water backflow in the third connecting pipe.

[0015] In one possible design, the blocking mechanism includes a limiting frame fixed to the inner wall of the water tank, a sealing plate located at the top of the limiting frame inside the water tank, a sliding rod fixedly mounted on the top of the sealing plate, a rotating shaft rotatably mounted through the top of the water tank, the output end of the first motor fixedly connected to the rotating shaft, a stirring spoon fixedly mounted on the rotating shaft, the top of the sliding rod extending into the rotating shaft, a rotating plate rotatably mounted on the inner wall of the rotating shaft, a spring mounted inside the rotating shaft, the two ends of the spring being fixedly connected to the adjacent sides of the rotating plate and the sliding rod, respectively, and a wedge block for cooperating with the sliding plate fixedly mounted at the bottom of the sealing plate.

[0016] In one possible design, two connecting plates are fixedly provided on one side of the water tank, and a fixed shaft is fixedly provided between the two connecting plates. A receiving roller is rotatably sleeved on the outer wall of the fixed shaft. One end of the fourth connecting pipe is fixed and wound around the receiving roller. A torsion spring is sleeved on the outer wall of the fixed shaft, and the two ends of the torsion spring are fixedly connected to the outer wall of the fixed shaft and the inner wall of the receiving roller, respectively.

[0017] In one possible design, a filter plate is slidably mounted on the inner wall of the water tank, and a reciprocating threaded area is provided on the rotating shaft. The filter plate is threaded onto the reciprocating threaded area to drive the filter plate to move up and down reciprocally to clean the inside of the water tank.

[0018] A method for using an automated irrigation device for paddy fields includes the following steps:

[0019] S1. First, add an appropriate amount of water and fertilizer to the water tank, and start the first motor to stir and mix.

[0020] S2. Then, start the second motor to drive the reciprocating screw to rotate, which in turn drives the sliding plate to move, squeezing the water in the bucket through the fourth connecting pipe and spraying it onto the plants through the nozzle.

[0021] S3. At the same time, the second motor drives the first connecting pipe to move, which in turn drives the spray pipe to move on one side of the plant, spraying water while moving.

[0022] S4. Finally, by starting the second motor to rotate in the opposite direction, the first connecting tube is driven to reset and move, while the fourth connecting tube automatically retracts.

[0023] In this application, firstly, an appropriate amount of water and fertilizer are added to the water tank, and the first motor is started to drive the rotating shaft to rotate. The mixing is carried out by the stirring spoon, and at the same time, the filter plate is moved up and down through the reciprocating thread area to clean the inner wall of the water tank and filter out impurities.

[0024] Then, the second motor is started to drive the rotating roller to rotate. The rotating roller drives the reciprocating screw to rotate through the bevel gear. The rotation of the reciprocating screw can drive the sliding plate to move inside the water bucket. When the sliding plate contacts the wedge, it will drive the sealing plate to move upward. At this time, the water will flow downward into the water bucket through the sealing plate and the limiting frame. As the sliding plate continues to move, it can squeeze the water in the water bucket through the fourth connecting pipe and spray it onto the plant through the spray pipe. At the same time, after the sliding plate moves away from the wedge, the wedge can move downward under the action of the spring to seal the limiting frame. Then, the first motor is started to drive the stirring spoon to stir.

[0025] At the same time, when the rotating roller is driven by the second motor, it will drive the first connecting pipe to move through the transmission belt, drive the spray pipe to move on one side of the plant, spray water while moving, and pull the fourth connecting pipe to move.

[0026] Finally, by starting the second motor to rotate in the opposite direction, the first connecting tube is driven to reset and move, while the fourth connecting tube can automatically retract under the force of the torsion spring.

[0027] In this invention, the automated irrigation device for paddy fields can not only drive multiple nozzles to move simultaneously by starting the second motor, but also drive the sliding plate to move inside the water bucket to squeeze water, so that the water is sprayed out through the nozzles for irrigation. This makes it convenient to use, requiring no manual pushing, and also eliminating the need for an additional water pump, thus saving manufacturing costs.

[0028] In this invention, the automated irrigation device for paddy fields can not only drive the stirring spoon to rotate and mix water and fertilizer by starting the first motor, but also drive the filter plate to move up and down to filter impurities in the water, and clean the inner wall of the water tank, effectively preventing the spray pipe from becoming blocked.

[0029] In this invention, the automated irrigation device for paddy fields can block the water in the water tank by using wedges and sliding plates in combination, which can effectively prevent water and fertilizer from flowing into the water bucket and affecting the mixing effect, thereby improving the degree of mixing between water and fertilizer.

[0030] In this invention, starting the second motor can simultaneously drive multiple nozzles to move, and can also drive the sliding plate to squeeze water, so that it does not require manual pushing. Furthermore, the water tank remains stationary, which can reduce the weight of the first connecting pipe, making it easy to move. It can also be stirred with a stirring spoon to ensure uniform mixing, making it convenient to use. Attached Figure Description

[0039] 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.

[0040] Example 1

[0041] Reference Figures 1-7 An automated irrigation device for paddy fields, used in agricultural planting, includes: a water tank 1 and a base plate 5 located on the ground on one side of the water tank 1. The top of the water tank 1 is provided with a feed inlet 2 for feeding. Multiple stirring spoons 20 for stirring the liquid are rotatably installed inside the water tank 1. A first motor 3 is fixedly installed on the top of the water tank 1. The output end of the first motor 3 is connected to the stirring spoons 20 to provide power to the stirring spoons 20.

[0042] A water bucket 23 is fixedly installed inside a water tank 1. A sliding plate 26 is slidably installed inside the water bucket 23. Two third connecting pipes 27 are fixedly installed through the bottom of the water tank 1. One end of the third connecting pipe 27 extends into the water bucket 23. The sliding plate 26 can move to squeeze the water in the water bucket 23 into the third connecting pipe 27 for irrigation.

[0043] The first connecting pipe 7 is slidably disposed on the top of the base plate 5. Two second connecting pipes 8 are fixedly disposed through the outer wall of the first connecting pipe 7. Multiple spray pipes 9 are fixedly disposed through the bottom of the second connecting pipes 8. The first connecting pipe 7 is connected to the two third connecting pipes 27 by a fourth connecting pipe 32 for guiding water so that water is sprayed toward the plants.

[0044] The second motor 12 is mounted on the base plate 5. Its output end is connected to the first connecting pipe 7 for driving the first connecting pipe 7 to move. It is also connected to the sliding plate 26 for driving the sliding plate 26 to reciprocate and squeeze water.

[0045] An intercepting mechanism, installed inside the water tank 1, seals the top of the water bucket 23 to prevent unmixed water and fertilizer from flowing into the bucket 23. Water and fertilizer are poured into the water tank 1, and the first motor 3 drives the stirring spoon 20 to rotate for mixing. Simultaneously, the intercepting mechanism blocks the mixing of water and fertilizer, improving the mixing effect. The second motor 12 moves the sliding plate 26, squeezing out water from the bucket 23 and spraying it onto the plants through the spray pipe 9. It also moves the first connecting pipe 7, allowing it to spray while moving, eliminating the need for manual pushing and improving irrigation efficiency.

[0046] Two side plates 11 are fixedly installed on the top of the base plate 5. Two rotating rollers 14 are rotatably installed between the two side plates 11. The outer walls of the two rotating rollers 14 are connected to the same transmission belt 13. The two ends of the transmission belt 13 are fixedly installed with the same sliding block 6. The first connecting pipe 7 is fixedly installed on the sliding block 6. The output end of the second motor 12 is fixedly connected to one of the rotating rollers 14. By starting the second motor 12, the rotating roller 14 can be driven to rotate. The rotation of the rotating roller 14 can drive the transmission belt 13 to move, thereby driving the first connecting pipe 7 to move through the sliding block 6. No manual pushing is required, saving manpower.

[0047] A reciprocating screw 24 is rotatably mounted on one side of the water tank 1, located inside the water bucket 23. A sliding plate 26 is threaded onto the reciprocating screw 24. A meshing bevel gear 10 is fixedly mounted on the adjacent ends of the reciprocating screw 24 and the rotating roller 14. A one-way valve 28 is provided on the third connecting pipe 27 to prevent water from flowing back into the third connecting pipe 27. When the second motor 12 drives the rotating roller 14 to rotate, it can drive the reciprocating screw 24 to rotate through the bevel gear 10. The rotation of the reciprocating screw 24 can drive the sliding plate 26 to move, squeezing out the water in the water bucket 23, so that no additional water pump is needed and maintenance is convenient.

[0048] The blocking mechanism includes a limiting frame 21 fixedly mounted on the inner wall of the water tank 1. A sealing plate 22 is located at the top of the limiting frame 21 inside the water tank 1. A sliding rod 33 is fixedly mounted on the top of the sealing plate 22. A rotating shaft 17 is rotatably mounted through the top of the water tank 1. The output end of the first motor 3 is fixedly connected to the rotating shaft 17. A stirring spoon 20 is fixedly mounted on the rotating shaft 17. The top of the sliding rod 33 extends into the rotating shaft 17. A rotating plate 34 is rotatably mounted on the inner wall of the rotating shaft 17. A spring 35 is located inside the rotating shaft 17. The two ends of the spring 35 are respectively close to the rotating plate 34 and the sliding rod 33. The sealing plate 22 is fixedly connected to the side, and a wedge 25 is fixedly provided at the bottom of the sealing plate 22 to cooperate with the sliding plate 26. When the sliding plate 26 moves, it will drive the sealing plate 22 to move upward through the wedge 25, so that the sealing plate 22 moves away from the limiting frame 21. At this time, the water in the water tank 1 can flow into the water bucket 23 through the gap between the limiting frame 21 and the sealing plate 22. When the sliding plate 26 moves away from the wedge 25, the sealing plate 22 can move downward under the action of the spring 35 to seal the limiting frame 21, so as to facilitate the stirring of water and fertilizer, improve the mixing effect, and prevent unmixed water and fertilizer from flowing into the water bucket 23.

[0049] A method for using an automated irrigation device for paddy fields includes the following steps:

[0050] S1. First, add an appropriate amount of water and fertilizer to the water tank 1, and start the first motor 3 to stir and mix.

[0051] S2. Then, start the second motor 12 to drive the reciprocating screw 24 to rotate, drive the sliding plate 26 to move, squeeze the water in the bucket 23 through the fourth connecting pipe 32, and spray it onto the plants through the spray pipe 9.

[0052] S3. At the same time, the second motor 12 drives the first connecting pipe 7 to move, which in turn drives the spray pipe 9 to move on one side of the plant, spraying water while moving.

[0053] S4. Finally, by starting the second motor 12 to rotate in the opposite direction, the first connecting tube 7 is reset and moved, while the fourth connecting tube 32 is automatically retracted.

[0054] Example 2

[0055] refer to Figure 3 , Figure 4 and Figure 7 Improvements based on Example 1:

[0056] Sliding blocks 6 have grooves 16 on both sides, and guide bars 15 are slidably installed in the grooves 16. The guide bars 15 are fixed on the inner side of the side plate 11 and are used to support and guide the sliding blocks 6. The cooperation between the guide bars 15 and the grooves 16 enables the sliding blocks 6 to be supported and guided, making them more stable during movement.

[0057] A filter plate 19 is slidably mounted on the inner wall of the water tank 1. A reciprocating threaded area 18 is provided on the rotating shaft 17. The filter plate 19 is threaded onto the reciprocating threaded area 18, which is used to drive the filter plate 19 to move up and down reciprocally to clean the inside of the water tank 1. When the first motor 3 is started and the rotating shaft 17 is rotated, the filter plate 19 will move up and down through the reciprocating threaded area 18, which can filter impurities in the water and clean impurities on the inner wall of the water tank 1, making it easy to clean.

[0058] Two connecting plates 4 are fixedly installed on one side of the water tank 1. A fixed shaft 30 is fixed between the two connecting plates 4. A collecting roller 29 is rotatably sleeved on the outer wall of the fixed shaft 30. One end of the fourth connecting pipe 32 is fixed and wound around the collecting roller 29. A torsion spring 31 is sleeved on the outer wall of the fixed shaft 30. The two ends of the torsion spring 31 are fixedly connected to the outer wall of the fixed shaft 30 and the inner wall of the collecting roller 29, respectively. When the first connecting pipe 7 moves, it will drive the fourth connecting pipe 32 to move. The movement of the fourth connecting pipe 32 will drive the collecting roller 29 to rotate and compress the torsion spring 31. When the first connecting pipe 7 returns to its original position, the collecting roller 29 can rotate repeatedly under the force of the torsion spring 31 to automatically collect the excess fourth connecting pipe 32.
