The pressure boosting component includes a piston tube. A second reciprocating screw is rotatably installed inside the piston tube. One end of the second reciprocating screw is fixedly connected to the other output end of the bidirectional motor. A threaded block is slidably connected to the second reciprocating screw. A second pipe is connected to one side of the piston tube. A block is slidably connected inside the second pipe. A push rod is fixedly connected to one side of the block. One end of the push rod is fixedly connected to one set of movable rods. One side of the second pipe is connected to one side of one set of telescopic pipes.

[0005] Preferably, a one-way clutch is provided at the connection between one set of output ends of the bidirectional motor and one end of the first reciprocating lead screw. The first reciprocating lead screw and the threaded sleeve are connected by a ball nut pair. A connecting frame is fixedly connected to one side of the threaded sleeve, and the connecting frame is fixedly connected to another set of moving frames of the adjustment component on one side.

[0006] Preferably, each pair of the telescopic pipes is connected by a connecting pipe, and one of the telescopic pipes is provided with a water inlet on one side.

[0007] Preferably, each of the two sets of fixed rods has a telescopic rod fixedly installed at one end, and a fixed frame is fixedly connected to one end of the telescopic rod. The fixed frame is fixedly connected to a set of movable frames of the adjustment component.

[0008] Preferably, the piston tube is fixedly installed on another set of movable frames of the telescopic bracket, and the piston tube has two sets of grooves inside. The threaded block has protrusions on both sides that slide on the two sets of grooves.

[0009] Preferably, the second reciprocating screw and the threaded block are connected by a ball nut pair, the threaded block is slidably connected to the inside of the piston tube, one end of the second reciprocating screw passes through the inside of the piston tube, and one end of the second reciprocating screw is fixedly connected to another set of output ends of the bidirectional motor.

[0011] Preferably, one end of the push rod penetrates the interior of the second pipe, and one end of the push rod is fixedly connected to one of the sets of movable rods.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In this invention, each set of movable rods extends each set of telescopic tubes via a telescopic frame, and each set of telescopic tubes extends the drip irrigation head. This allows each set of drip irrigation heads to be adjusted to a suitable distance according to the crop growth cycle, preventing the fixed spacing of drip holes in traditional drip irrigation tapes from being difficult to adapt to changes in plant spacing during the crop growth cycle. Furthermore, manual adjustment can easily lead to spacing errors, affecting irrigation uniformity.

[0013] In this invention, one set of movable rods in the adjusting component drives two sets of gears to rotate via one set of racks. Each set of gears drives a fixed rod to move downwards via another set of racks, causing the two sets of fixed rods to move into the soil as the adjusting component extends. This ensures that the two sets of fixed rods provide stable support for the adjusting component, preventing it from becoming less stable as it extends further, which could lead to the adjusting component tipping over, affecting the drip irrigation of crops, or even causing the adjusting component to crush the crops and kill them.

[0014] This invention adjusts the opening size at the connection point between the second pipe and the first and third pipes based on the extension distance of each set of telescopic tubes driven by the adjusting component. Gas is transmitted through the first, second, and third pipes to one of the sets of telescopic tubes for internal use. The gas is then transmitted through each set of telescopic tubes and each set of connecting pipes to assist the water flow inside each set of telescopic tubes. This prevents the water pressure inside each set of telescopic tubes from becoming constant. When each set of telescopic tubes is extended and adjusted, the air pressure inside each set of telescopic tubes decreases, which leads to a slower water flow rate and a reduced water output, affecting the irrigation effect of the drip irrigation head and causing uneven irrigation. The pressurizing component can adjust the opening size at the pipe connection point according to the extension distance to assist the water flow. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] See Figures 1 to 4 As shown, the present invention provides an adjustable-spacing drip irrigation device for agricultural irrigation, including an adjustment component 1. The adjustment component 1 includes a telescopic bracket 101. A bidirectional motor 102 is fixedly installed on one set of movable frames of the telescopic bracket 101. A first reciprocating screw 104 is fixedly connected to one set of output ends of the bidirectional motor 102. A threaded sleeve 105 is slidably connected to the first reciprocating screw 104. One side of the threaded sleeve 105 is fixedly connected to another set of movable frames of the telescopic bracket 101. A telescopic frame 106 is installed on the movable rod 110 at the connection of every two sets of connecting rods of the telescopic bracket 101. A telescopic pipe 107 is fixedly installed on one side of each set of telescopic frames 106. A drip irrigation head 108 is provided on one side of each telescopic pipe 107. The operator starts the bidirectional motor 102 to rotate forward. The bidirectional motor 102 drives the first reciprocating screw 104 to rotate via the one-way clutch 103. Since the first reciprocating screw 104 is connected to the threaded sleeve 105 via a ball nut pair, the first reciprocating screw 104 drives the threaded sleeve 105 to move. The threaded sleeve 105 drives the telescopic bracket 101 to extend via the connecting frame. The movable rod 110 at the connection of every two sets of connecting rods of the telescopic bracket 101 is adjusted by the telescopic frame 106. Each set of movable rods 110 drives each... The telescopic pipes 107 are extended, and each telescopic pipe 107 drives the drip irrigation head 108 to extend, so that each drip irrigation head 108 is adjusted to a suitable distance according to the crop growth cycle. Then, the staff connects the water source to the inlet of one of the telescopic pipes 107. The water source is transported through each telescopic pipe 107 and the connecting pipe in sequence. The water source drips onto the crop through each drip irrigation head 108. This prevents the fixed spacing of the drip holes of the traditional drip irrigation tape from being difficult to adapt to the changes in plant spacing during the crop growth cycle. In addition, manual adjustment is prone to spacing errors, which affect the uniformity of irrigation. See Figure 5As shown, a fixing component 2 is installed on the adjusting component 1. The fixing component 2 includes a protective frame 201 fixedly installed on another set of movable frames of the telescopic bracket 101. A gear 202 is rotatably installed inside the protective frame 201. A rack 203 meshes with both sides of the gear 202. One set of racks 203 is fixedly connected to one set of telescopic brackets 101, and a fixing rod 204 is fixedly installed on one side of the other set of racks 203. When the adjusting component 1 extends, one set of movable rods 110 of the adjusting component 1 drives two sets of gears 202 to rotate through one set of racks 203. Each set of gears 202 drives the fixed rods 204 to move downward through the other set of racks 203, so that the two sets of fixed rods 204 move into the soil along with the extension distance of the adjusting component 1. This ensures that the two sets of fixed rods 204 provide stable support for the adjusting component 1, preventing the adjusting component 1 from becoming less stable as the extension distance increases, which could cause the adjusting component 1 to tip over, thereby affecting the drip irrigation of the crop, or even causing the adjusting component 1 to crush the crop and cause the crop to die. Additionally, two sets of telescopic rods 205 are provided on the two sets of fixed rods 204. The two sets of telescopic rods 205 are used to extend and retract as the fixed rods 204 move, and to fix the two sets of fixed rods 204 to ensure that the fixed rods 204 can operate normally. See Figures 6 to 7 As shown, a booster assembly 3 is fixedly installed on the adjusting assembly 1. The booster assembly 3 includes a piston tube 303. A second reciprocating screw 301 is rotatably installed inside the piston tube 303. One end of the second reciprocating screw 301 is fixedly connected to the output end of the other end of the bidirectional motor 102. A threaded block 302 is slidably connected to the second reciprocating screw 301. A second pipe 305 is connected to one side of the piston tube 303. A block 307 is slidably connected inside the second pipe 305. A push rod 308 is fixedly connected to one side of the block 307. One end of the push rod 308 is fixedly connected to one of the movable rods 110. One side of the second pipe 305 is connected to one side of one of the telescopic pipes 107. When the adjusting component 1 is fully extended, the operator starts the bidirectional motor 102 in reverse. The first reciprocating screw 104, adjusted by the one-way clutch 103, is no longer driven by the bidirectional motor 102, maintaining the stability of the adjusting component 1. The bidirectional motor 102 then drives the second reciprocating screw 301 to rotate. Since the second reciprocating screw 301 is connected to the threaded block 302 via a ball nut pair, and the protrusions on both sides of the threaded block 302 slide on the two sets of grooves in the piston tube 303, the threaded block 302 moves inside the piston tube 303, compressing the gas inside. Simultaneously, as one set of movable rods 110 of the adjusting component 1 drives two sets of gears 202 to rotate via one set of racks 203, the movable rod 110 drives the push rod 308 to move upwards. The push rod 308 then drives the block 307 inside the second pipe 305 to move upwards, opening the connection between the second pipe 305 and the first pipe 305. At the connection point of 04 and the third pipe 306, the push rod 308 follows the extension distance of the adjusting component 1, causing the block 307 to move internally. According to the extension distance of each set of telescopic pipes 107 driven by the adjusting component 1, the opening size of the connection point between the second pipe 305 and the first pipe 304 and the third pipe 306 is adjusted. Gas is transmitted through the first pipe 304, the second pipe 305, and the third pipe 306 to one of the sets of telescopic pipes 107 for internal use. The gas is then transmitted through each set of telescopic pipes 107 and each set of connecting pipes to assist the water flow inside each set of telescopic pipes 107. This prevents the water pressure inside each set of telescopic pipes 107 from being constant. When each set of telescopic pipes 107 is extended and adjusted, the air pressure inside each set of telescopic pipes 107 decreases, which will cause the water flow speed to slow down and the water output to decrease, affecting the irrigation effect of the drip irrigation head 108 and causing uneven irrigation. The pressurizing component 3 can adjust the opening size of the pipe connection point according to the extension distance to assist the water flow.

[0019] In an optional embodiment, a one-way clutch 103 is provided at the connection between one set of output ends of the bidirectional motor 102 and one end of the first reciprocating lead screw 104. The first reciprocating lead screw 104 is connected to the threaded sleeve 105 through a ball nut pair. A connecting frame is fixedly connected to one side of the threaded sleeve 105, and the connecting frame is fixedly connected to another set of moving frames of the adjusting assembly 1 on one side.

[0020] It should be noted that when the operator starts the bidirectional motor 102 to reverse, the first reciprocating screw 104 is adjusted by the one-way clutch 103, and the bidirectional motor 102 no longer drives the first reciprocating screw 104 to rotate, thus maintaining the stability of the adjustment component 1. Since the first reciprocating screw 104 and the threaded sleeve 105 are connected by a ball nut pair, the first reciprocating screw 104 drives the threaded sleeve 105 to move.

[0021] In an optional embodiment, every two sets of telescopic pipes 107 are connected by a connecting pipe, and one set of telescopic pipes 107 has a water inlet on one side.

[0022] It should be noted that the staff connects the water source to the inlet of one set of telescopic pipes 107, and the water source is transported through each set of telescopic pipes 107 and the connecting pipe in sequence. The water source is drip-irrigated to the crops through each set of drip irrigation heads 108.

[0023] In an optional embodiment, each of the two sets of fixed rods 204 has a telescopic rod 205 fixedly installed at one end, and a fixed frame is fixedly connected to one end of the telescopic rod 205. The fixed frame is fixedly connected to a set of movable frames of the adjustment component 1.

[0024] It should be noted that two sets of telescopic rods 205 are provided on the two sets of fixed rods 204. The two sets of telescopic rods 205 are used to extend and retract as the fixed rods 204 move, to fix the two sets of fixed rods 204 and ensure that the fixed rods 204 can operate normally.

[0025] In an optional embodiment, the piston tube 303 is fixedly mounted on another set of movable frames of the telescopic bracket 101. The piston tube 303 has two sets of grooves inside, and the threaded block 302 has protrusions on both sides that slide on the two sets of grooves.

[0026] It should be noted that since the protrusions on both sides of the threaded block 302 are provided to slide on the two sets of grooves of the piston tube 303, the threaded block 302 moves inside the piston tube 303 and compresses the gas inside the piston tube 303.

[0027] In an optional embodiment, the second reciprocating screw 301 is connected to the threaded block 302 via a ball nut pair, the threaded block 302 is slidably connected to the inside of the piston tube 303, one end of the second reciprocating screw 301 passes through the inside of the piston tube 303, and one end of the second reciprocating screw 301 is fixedly connected to another set of output ends of the bidirectional motor 102.

[0028] It should be noted that, since the second reciprocating screw 301 and the threaded block 302 are connected by a ball nut pair, and the protrusions on both sides of the threaded block 302 are provided to slide on the two sets of grooves of the piston tube 303, the second reciprocating screw 301 drives the threaded block 302 to slide inside the piston tube 303.

[0029] In an optional embodiment, a first pipe 304 is connected to one side of the piston tube 303, one end of the first pipe 304 is fixedly connected to a second pipe 305, a third pipe 306 is connected to one side of the second pipe 305, and one end of the third pipe 306 is connected to one side of one set of telescopic pipes 107.

[0030] It should be noted that the gas is transmitted through the first pipe 304, the second pipe 305, and the third pipe 306 to one of the sets of telescopic pipes 107 for internal use.

[0031] In an optional embodiment, one end of the push rod 308 penetrates the interior of the second pipe 305, and one end of the push rod 308 is fixedly connected to one of the sets of movable rods 110.

[0032] It should be noted that the movable rod 110 drives the push rod 308 to move upward, which in turn causes the push rod 308 to move the block 307 inside the second pipe 305 upward.

[0033] Working principle: The operator starts the bidirectional motor 102 to rotate forward. The bidirectional motor 102 drives the first reciprocating screw 104 to rotate through the one-way clutch 103. The first reciprocating screw 104 drives the threaded sleeve 105 to move. The threaded sleeve 105 drives the telescopic bracket 101 to extend through the connecting frame. The movable rod 110 at the connection of each pair of connecting rods of the telescopic bracket 101 is adjusted by the telescopic frame 106. Each movable rod 110 drives each telescopic pipe 107 to extend through the telescopic frame 106. Each telescopic pipe 107 drives the drip irrigation head 108 to extend, so that each drip irrigation head 108 is adjusted to a suitable distance according to the crop growth cycle. Then the operator connects the water source to the inlet of one of the telescopic pipes 107. The water source is transported through each telescopic pipe 107 and the connecting pipe in sequence. The water source drips onto the crop through each drip irrigation head 108. When the adjusting component 1 extends, one set of movable rods 110 of the adjusting component 1 drives two sets of gears 202 to rotate through one set of racks 203. Each set of gears 202 drives the fixed rods 204 to move downward through another set of racks 203, so that the two sets of fixed rods 204 move into the soil along with the extension distance of the adjusting component 1, ensuring that the two sets of fixed rods 204 provide stable support for the adjusting component 1. When the adjusting component 1 is fully extended, the operator starts the bidirectional motor 102 in reverse. The first reciprocating screw 104, adjusted by the one-way clutch 103, is no longer driven by the bidirectional motor 102 to rotate, maintaining the stability of the adjusting component 1. The bidirectional motor 102 then drives the second reciprocating screw 301 to rotate. Since the second reciprocating screw 301 is connected to the threaded block 302 via a ball nut pair, and the protrusions on both sides of the threaded block 302 slide on the two sets of grooves in the piston tube 303, the threaded block 302 moves inside the piston tube 303, compressing the gas inside. Simultaneously, one set of movable rods 110 of the adjusting component 1 drives two sets of gears 202 to rotate via one set of racks 203, while the movable rods 110... The push rod 308 moves upward, causing the block 307 inside the second pipe 305 to move upward. The block 307 moves and opens the connection between the second pipe 305, the first pipe 304, and the third pipe 306, allowing the push rod 308 to follow the extension distance of the adjusting component 1 and move the block 307 inside. According to the extension distance of each set of telescopic pipes 107 driven by the adjusting component 1, the opening size of the connection between the second pipe 305 and the first pipe 304 and the third pipe 306 is adjusted. Gas is transmitted through the first pipe 304, the second pipe 305, and the third pipe 306 to one of the sets of telescopic pipes 107 for internal transmission. The gas is then transmitted through each set of telescopic pipes 107 and each set of connecting pipes, assisting the flow of water inside each set of telescopic pipes 107.
