Description

Technical Field

[0001] The invention relates to the technical field of water and fertilizer irrigation equipment, and in particular to a water and fertilizer integrated irrigation device and a use method thereof. Background Art

[0002] Irrigation refers to technical measures to supplement the water needed by crops. In order to ensure normal growth and high and stable yields of crops, crops need to be given sufficient water. Under natural conditions, the water requirements of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation is necessary to make up for the lack of natural rainfall.

[0003] When using the integrated water and fertilizer irrigation device, the prepared water and fertilizer are usually sprayed outward through the irrigation pipe to irrigate the crops. However, during irrigation, since the irrigation pipe is long and fixed, it is difficult to move the irrigation pipe whether it is laid on the muddy land to be irrigated or installed on a mobile cart. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a water-fertilizer integrated irrigation device, comprising a frame, a first fixed bracket is fixedly connected to the top of the frame, a second fixed bracket is fixedly connected to the top of the frame, and a third fixed bracket is fixedly connected to the top of the frame;

[0005] The filtering and stirring mechanism includes a fertilizer stirring barrel, a water and fertilizer control box for controlling the inflow and outflow of water and fertilizer in the fertilizer stirring barrel, a centrifugal filter, a water inlet, a double-net filter, a water outlet, a connecting pipe, a connecting pipe, and a telescopic irrigation mechanism for controlling the irrigation range of water and fertilizer in the fertilizer stirring barrel;

[0006] The bottom of the fertilizer mixing barrel is fixedly connected to the top of the frame, the bottom of the water and fertilizer control box is fixedly connected to the top of the frame, the bottom of the centrifugal filter is fixedly connected to the top of the fixed bracket one, the bottom of the double-net filter is fixedly connected to the top of the fixed bracket two, the outer wall of the connecting pipe is fixedly connected to the inner wall of the centrifugal filter, the outer wall of the connecting pipe is fixedly connected to the inner wall of the double-net filter, the outer wall of the connecting pipe is fixedly connected to the inner wall of the connecting pipe, and the outer wall of the connecting pipe is fixedly connected to the inner wall of the fertilizer mixing barrel.

[0007] Preferably, the telescopic irrigation mechanism includes a water outlet pipe fixedly connected to the inner wall of the fixed bracket three, the outer wall of the water outlet pipe is fixedly connected to the outer wall of the water outlet, the inner wall of the water outlet pipe is slidably connected with a telescopic tube 1, the outer wall of the telescopic tube 1 is fixedly connected with a discharge pipe, the inner wall of the telescopic tube 1 is slidably connected with a leak-proof component, and the inner wall of the discharge pipe is slidably connected with a root irrigation component. After the processed water and fertilizer come out through the water outlet, they will push the telescopic tube 1 to move outward through the water outlet pipe. When the telescopic tube 1 moves outward, it will simultaneously drive the discharge pipe to move, so that it moves to a specified distance, and then the water and fertilizer fall to irrigate the crops within the range.

[0008] Preferably, the telescopic irrigation mechanism also includes a fixed rod fixedly connected to the top of the fixed bracket three, a pulley is rotatably connected to the outer wall of the fixed rod, and the top of the fixed bracket three is fixedly connected to the fixed bracket four. The position of the pulley can be fixed by the fixed rod, so that the pulley can rotate normally at the specified position on the fixed rod to avoid its position deviation and affect the normal operation of subsequent components.

[0009] Preferably, the telescopic irrigation mechanism also includes a rotating shaft rotatably connected to the inner wall of the fixed bracket, a rotating plate is fixedly connected to the outer wall of the rotating shaft, a pull rope is fixedly connected to the top of the rotating plate, the outer wall of the pull rope is fixedly connected to the outer wall of the telescopic tube, and the outer wall of the pull rope is rotatably connected to the inner wall of the pulley. Utilizing the characteristic that after water and fertilizer come out of the water outlet, they will pass through the water outlet pipe and then push the telescopic tube to move outward, a plurality of discharge pipes are arranged, and after the processed water and fertilizer come out through the water outlet, they will pass through the water outlet pipe and then push the telescopic tube to move outward. When the telescopic tube moves outward, the discharge pipe is synchronously driven to move, so that it moves to a specified distance, and then the water and fertilizer fall to irrigate the crops within the range. In addition, when the telescopic tube moves outward, the rotating plate can be pulled with the rotating shaft as the center through the pull rope and the pulley. The axis rotates, and then after the water and fertilizer are used up or the water and fertilizer delivery is stopped, the telescopic tube 1 is no longer subjected to the thrust of the water and fertilizer. Under the action of the counterweight block and the arc spring, the telescopic tube 1 is pulled to reset by the rotating plate and the pull rope. Through the operation of the above components, the discharge pipe can be automatically adjusted to the specified position to irrigate the crops when water and fertilizer are irrigated. At the end of irrigation, it can be automatically recovered to facilitate the normal movement of the equipment when not in use, avoiding the difficulty of moving the equipment due to the fixed irrigation pipe being too long. At the same time, the pulley, the rotating plate and the pull rope can also form a protective support for the telescopic tube 1, avoiding the telescopic tube 1 from being bent or damaged due to excessive pressure caused by the telescopic tube 1 moving too long and the presence of water and fertilizer inside, thereby affecting its normal telescopic movement.

[0010] Preferably, the telescopic irrigation mechanism also includes a counterweight block fixedly connected to the bottom of the rotating plate, the bottom of the rotating plate is fixedly connected to an arc spring, the outer wall of the arc spring is fixedly connected to the top of the fixed bracket three at one end away from the rotating plate, and the above-mentioned characteristics are utilized, when the telescopic tube 1 moves, the rotating plate can be pulled to rotate by the pull rope, when the telescopic tube 1 is moved outward by the thrust of water and fertilizer, the rotating plate can be pulled to rotate with the rotating shaft as the axis through the pull rope and the pulley, and when the rotating plate rotates upward, several pull ropes can be moved together, and when the telescopic tube 1 is moving, when a certain section of the telescopic tube 1 moves longer, the pull ropes on the remaining sections of the telescopic tube 1 The rope will be in a loose state, and at this time the water and fertilizer will give priority to pushing these sections of the telescopic tube 1, so that they maintain a relatively equal distance with another section of the telescopic tube 1. At the same time, when the rotating plate is rotated downward by the counterweight and the arc spring, each section of the telescopic tube 1 can also be pulled to move synchronously through the rotating plate and the pull rope. Through the operation of the above components, it is avoided that when the telescopic tube 1 moves, the moving distance of each section is uncontrollable, some moving distances are longer, and some moving distances are shorter, resulting in some discharge pipes starting to discharge water and fertilizer, while others have not yet discharged water and fertilizer, causing uneven irrigation when the equipment is irrigating water and fertilizer, thereby affecting the growth of crops.

[0011] Preferably, the leakage-proof component includes a sliding partition slidably connected to the inner wall of the telescopic tube, a fixed plate is fixedly connected to the top of the sliding partition, a telescopic spring is fixedly connected to the outer wall of the fixed plate, and one end of the outer wall of the telescopic spring away from the fixed plate is fixedly connected to the inner wall of the telescopic tube. When the water and fertilizer push the telescopic tube at the rear end to move outward, the sliding partition is synchronously driven to move through the fixed plate and the telescopic spring, so that the discharge pipe at the rear end remains in a closed state like the other discharge pipes.

[0012] Preferably, the leak-proof component also includes a fixed block fixedly connected to the top of the sliding partition, an inclined sliding block is slidably connected to the inner wall of the fixed block, a telescopic spring 2 is fixedly connected to the top of the inclined sliding block, a groove is provided on the inner wall of the telescopic tube 1, and a sliding partition is provided by utilizing the characteristic that the water and fertilizer push the telescopic tube 1 to move outward. When the water and fertilizer push the telescopic tube 1 at the rear end to move outward, the sliding partition is synchronously driven to move through the fixed plate and the telescopic spring 1, so that the discharge tube at the rear end remains in a closed state like the other discharge tubes. When the telescopic tube 1 continues to move outward, the inclined sliding block will contact the groove. When the inclined sliding block contacts the groove, the telescopic spring 2 will cause the inclined sliding block to get stuck. When the telescopic tube 1 is in the groove, and the telescopic tube 1 continues to move outward, the discharge pipe on the telescopic tube 1 at the rearmost end will be changed from a closed state to an open state together with the other discharge pipes. At this time, the water and fertilizer can flow into the discharge pipe. When the telescopic tube 1 retracts, due to the design of the inclined surface of the inclined slider, the inclined slider will gradually retract and reset, and the telescopic tube 1 will reset at the same time. Through the operation of the above components, the discharge pipe at the rearmost telescopic tube can be opened and closed together with the other discharge pipes, so as to avoid the water and fertilizer from flowing out from the discharge pipe at the rearmost end when the telescopic tube 1 moves, which not only affects the uniformity of irrigation, but also causes waste of water and fertilizer and affects the speed of the telescopic tube 1 moving outward, thereby reducing work efficiency.

[0013] Preferably, the root irrigation assembly includes a telescopic tube 2 slidably connected to the inner wall of the discharge pipe, a nozzle is fixedly connected to the outer wall of the telescopic tube 2, a connecting rod is fixedly connected to the bottom of the telescopic tube 2, and a roller is rotatably connected to the outer wall of the connecting rod. After water and fertilizer flow into the discharge pipe through the telescopic tube 1, the telescopic tube 2 will be pushed to move downward. When the telescopic tube 2 moves downward, the roller is driven to move downward synchronously through the connecting rod until the roller contacts the ground, so that the nozzle is roughly directed to the root and stem position of the crop.

[0014] Preferably, the root irrigation assembly also includes a connecting block 1 fixedly connected to the inner wall of the discharge pipe, a connecting block 2 is fixedly connected to the inner wall of the telescopic tube 2, a telescopic spring 3 is fixedly connected to the top of the connecting block 2, and one end of the outer wall of the telescopic spring 3 away from the connecting block 2 is fixedly connected to the bottom of the connecting block 1. By utilizing the characteristic that water and fertilizer will push the telescopic tube 2 to move downward after entering the discharge pipe, a plurality of nozzles are provided. After the water and fertilizer flow into the discharge pipe through the telescopic tube 1, they will in turn push the telescopic tube 2 to move downward. When the telescopic tube 2 moves downward, the roller is driven to move downward synchronously through the connecting rod until the roller contacts the ground, so that the nozzle is roughly oriented to the root position of the crop. At the same time, when the water and fertilizer are pushed and moved, they will also enter the telescopic tube two, and then be sprayed out through the nozzle, so that the water and fertilizer can be directly irrigated to the root and stem position of the crop, so that the water and fertilizer can irrigate the crop more effectively. After the irrigation is completed, the top of the discharge pipe is closed, and the telescopic tube two is acted upon by the telescopic spring three to drive the roller to reset, so as to reduce the overall volume of the equipment and facilitate subsequent movement. In addition, the remaining water and fertilizer can also be discharged. Through the operation of the above components, the root and stem position of the crop can be irrigated more specifically, avoiding large-scale irrigation, and the effective water and fertilizer obtained by the crop is low, which will not only cause waste of water and fertilizer but also increase the overall cost.

[0015] A method for using a water-fertilizer integrated irrigation device comprises the following steps:

[0016] S1: Water and fertilizer modulation: Before using the device, first move the device to the required position, add water and fertilizer into the fertilizer mixing bucket, then connect the water inlet pipe to the water inlet, and start the water and fertilizer control box to modulate water and fertilizer. After the water and fertilizer are processed, disconnect the water inlet pipe;

[0017] S2: Start the equipment: After the processed water and fertilizer come out through the water outlet, they will push the telescopic tube 1 to move outward through the water outlet pipe. When the telescopic tube 1 moves outward, it will simultaneously drive the discharge pipe to move to the specified distance, and then the water and fertilizer will fall to irrigate the crops within the range.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that after water and fertilizer come out of the water outlet, they will push the telescopic tube 1 to move outward through the water outlet pipe, and set a plurality of discharge pipes. After the processed water and fertilizer come out of the water outlet, they will push the telescopic tube 1 to move outward through the water outlet pipe. When the telescopic tube 1 moves outward, it will synchronously drive the discharge pipe to move, so that it moves to a specified distance, and then the water and fertilizer fall to irrigate the crops within the range. In addition, when the telescopic tube 1 moves outward, the pull rope and the pulley can pull the rotating plate to rotate with the rotating shaft as the axis. Then, after the water and fertilizer are used up or the water and fertilizer delivery is stopped, the telescopic tube 1 is no longer subjected to the thrust of the water and fertilizer, and the counterweight block and the arc spring are used to irrigate the crops. Under the action of the spring, the telescopic tube 1 is pulled to reset by the rotating plate and the pull rope. Through the operation of the above components, the discharge pipe can be automatically adjusted to the specified position to irrigate the crops when water and fertilizer are irrigated. At the end of irrigation, it can be automatically recovered to facilitate the normal movement of the equipment when not in use, avoiding the difficulty of moving the equipment due to the fixed irrigation pipe being too long. At the same time, the pulley, the rotating plate and the pull rope can also form a protective support for the telescopic tube 1, avoiding the telescopic tube 1 from being bent or damaged due to excessive pressure due to the telescopic tube 1 moving too long and the presence of water and fertilizer inside, thereby affecting its normal telescopic movement.

[0020] (2) The present invention utilizes the above-mentioned characteristic that when the telescopic tube 1 moves, the rotating plate can be pulled to rotate by the pull rope. When the telescopic tube 1 is pushed outward by the water fertilizer, the rotating plate can be pulled to rotate with the rotating shaft as the axis through the pull rope and the pulley. When the rotating plate rotates upward, several pull ropes can be moved together. When the telescopic tube 1 moves, when a certain section of the telescopic tube 1 moves longer, the pull ropes on the remaining sections of the telescopic tube 1 will be in a relatively loose state. At this time, the water fertilizer will preferentially push these sections of the telescopic tube 1 to make them move with the other sections. A section of the telescopic tube maintains a relatively equal distance. At the same time, when the rotating plate is rotated downward by the counterweight and the arc spring, each section of the telescopic tube can be pulled to move synchronously through the rotating plate and the pull rope. Through the operation of the above components, it is avoided that the moving distance of each section of the telescopic tube is uncontrollable when it moves, and some moving distances are longer and some moving distances are shorter, resulting in some discharge pipes starting to discharge water and fertilizer while others have not yet discharged water and fertilizer, causing uneven irrigation when the equipment is irrigating water and fertilizer, thereby affecting the growth of crops.

[0021] (3) The present invention utilizes the characteristic that the water and fertilizer push the telescopic tube 1 to move outward, and sets a sliding partition. When the water and fertilizer push the telescopic tube 1 at the rear end to move outward, the sliding partition is synchronously driven to move through the fixed plate and the telescopic spring 1, so that the discharge pipe at the rear end is kept in a closed state like the other discharge pipes. When the telescopic tube 1 continues to move outward, the inclined slider contacts the groove. When the inclined slider contacts the groove, the inclined slider is stuck in the groove under the action of the telescopic spring 2. At this time, the telescopic tube 1 continues to move outward, and the discharge pipe on the telescopic tube 1 at the rear end is separated from the other discharge pipes. When the telescopic tube is retracted, due to the design of the inclined surface of the inclined slider, the inclined slider will gradually retract and reset, and the telescopic tube will reset at the same time. Through the operation of the above components, the discharge pipe at the very end of the telescopic tube can be opened and closed together with the remaining discharge pipes, so as to avoid the water and fertilizer from flowing out from the very end of the discharge pipe when the telescopic tube is moving, which not only affects the uniformity of irrigation, but also causes waste of water and fertilizer and affects the speed of the telescopic tube moving outward, thereby reducing work efficiency.

[0022] (4) The present invention utilizes the characteristic that after water and fertilizer enter the discharge pipe, they will push the telescopic tube 2 to move downward, and sets a plurality of nozzles. After water and fertilizer flow into the discharge pipe through the telescopic tube 1, they will push the telescopic tube 2 to move downward. When the telescopic tube 2 moves downward, the roller is driven to move downward synchronously through the connecting rod until the roller contacts the ground, so that the nozzle is roughly oriented to the root and stem position of the crop. At the same time, when the water and fertilizer are pushed to move, they will also enter the telescopic tube 2, and then be sprayed outward through the nozzle, so that the water and fertilizer can be directly irrigated to the root and stem position of the crop, so that the water and fertilizer can irrigate the crop more effectively. After the irrigation is completed, the top of the discharge pipe is closed, and the telescopic tube 2 is acted on by the telescopic spring 3 to drive the roller to reset, so as to reduce the overall volume of the equipment and facilitate subsequent movement. In addition, the remaining water and fertilizer can be discharged. Through the operation of the above components, the root and stem position of the crop can be irrigated more specifically, avoiding large-scale irrigation. The effective water and fertilizer obtained by the crop is low, which not only causes waste of water and fertilizer but also increases the overall cost. BRIEF DESCRIPTION OF THE DRAWINGS

After the processed water and fertilizer come out through the water outlet 206, they will pass through the water outlet pipe 301 and then push the telescopic tube 1 302 to move outward. When the telescopic tube 1 302 moves outward, it will simultaneously drive the discharge pipe 303 to move, so that it moves to a specified distance, and then the water and fertilizer fall to irrigate the crops within the range.

After the processed water and fertilizer come out through the water outlet 206, they will push the telescopic tube 302 outward through the water outlet pipe 301. When the telescopic tube 302 moves outward, the discharge pipe 303 is driven to move synchronously, so that the discharge pipe 303 moves to a specified distance, and then the water and fertilizer fall to irrigate the crops within the range. In addition, when the telescopic tube 302 moves outward, the pull rope 309 and the pulley 305 can be used to pull the crops. The movable rotating plate 308 rotates with the rotating shaft 307 as the axis. Then, after the water and fertilizer are used up or the water and fertilizer delivery is stopped, the telescopic tube 302 is no longer subjected to the thrust of the water and fertilizer. Under the action of the counterweight block 310 and the arc spring 311, the telescopic tube 302 is pulled to reset by the rotating plate 308 and the pull rope 309. Through the operation of the above components, when water and fertilizer are irrigated, the discharge pipe 303 can be automatically adjusted to the specified position to irrigate the crops. At the end of irrigation, it can be automatically recovered to facilitate the normal movement of the equipment when not in use, avoiding the difficulty of moving the equipment due to the fixed irrigation pipe being too long. At the same time, the pulley 305, the rotating plate 308 and the pull rope 309 can also form a protective support for the telescopic tube 302, avoiding the telescopic tube 302 from moving too long and the presence of water and fertilizer inside it, causing the telescopic tube 302 to be bent or damaged due to excessive pressure, thereby affecting its normal telescopic movement.

[0043] The telescopic irrigation mechanism 3 also includes a counterweight block 310 fixedly connected to the bottom of the rotating plate 308, and an arc spring 311 is fixedly connected to the bottom of the rotating plate 308. The end of the outer wall of the arc spring 311 away from the rotating plate 308 is fixedly connected to the top of the fixed bracket 3103.

When the rotating plate 308 rotates upward, several pull ropes 309 can be moved together. When the telescopic tube 302 is moving, when a certain section of the telescopic tube 302 moves longer, the remaining The pull ropes 309 on the several sections of the telescopic tube 302 will be in a loose state, and at this time the water and fertilizer will give priority to pushing these sections of the telescopic tube 302 to keep a relatively equal distance with another section of the telescopic tube 302. At the same time, when the rotating plate 308 is rotated downward by the counterweight block 310 and the arc spring 311, each section of the telescopic tube 302 can also be pulled to move synchronously through the rotating plate 308 and the pull rope 309.

[0044] For example 2, please refer to Figure 5 - Fig.10 The present invention is a water-fertilizer integrated irrigation device. On the basis of the first embodiment, the leakage-proof component 4 includes a sliding partition 401 slidably connected to the inner wall of the telescopic tube 302, the top of the sliding partition 401 is fixedly connected to the fixed plate 402, the outer wall of the fixed plate 402 is fixedly connected to the telescopic spring 403, and the end of the outer wall of the telescopic spring 403 away from the fixed plate 402 is fixedly connected to the inner wall of the telescopic tube 302. When the water and fertilizer push the telescopic tube 302 at the rear end to move outward, the sliding partition 401 is synchronously driven to move through the fixed plate 402 and the telescopic spring 403, so that the discharge pipe 303 at the rear end remains in a closed state like the other discharge pipes 303.

[0045] The anti-leakage component 4 also includes a fixed block 404 fixedly connected to the top of the sliding partition 401, and an inclined slider 405 is slidably connected to the inner wall of the fixed block 404. A telescopic spring 2 406 is fixedly connected to the top of the inclined slider 405. A groove 407 is provided on the inner wall of the telescopic tube 1 302. By utilizing the characteristic that the water and fertilizer push the telescopic tube 1 302 to move outward, a sliding partition 401 is set. When the water and fertilizer push the telescopic tube 1 302 at the rear end to move outward, the sliding partition 401 is synchronously driven to move through the fixed plate 402 and the telescopic spring 1 403, so that the discharge pipe 303 at the rear end is kept in a closed state like the other discharge pipes 303. When the telescopic tube 1 302 continues to move outward, the inclined slider 405 is brought into contact with the groove 407. When the inclined slider 405 is brought into contact with the groove 407, the telescopic spring 2 406 acts to make the inclined slider 405 When the hopper 302 is in the open position, the water and fertilizer can flow into the hopper 303. When the hopper 302 is in the open position, the water and fertilizer can flow into the hopper 303. When the hopper 302 is in the open position, the water and fertilizer can flow into the hopper 303. When the hopper 302 is in the open position, the water and fertilizer can flow into the hopper 303. When the hopper 302 is in the open position, the water and fertilizer can flow into the hopper 303.

[0046] The root irrigation assembly 5 includes a telescopic tube 501 slidably connected to the inner wall of the discharge pipe 303, a nozzle 502 is fixedly connected to the outer wall of the telescopic tube 501, a connecting rod 503 is fixedly connected to the bottom of the telescopic tube 501, and a roller 504 is rotatably connected to the outer wall of the connecting rod 503. After water and fertilizer flow into the discharge pipe 303 through the telescopic tube 1 302, the telescopic tube 501 is pushed to move downward. When the telescopic tube 501 moves downward, the roller 504 is driven to move downward synchronously through the connecting rod 503 until the roller 504 contacts the ground, so that the nozzle 502 is roughly oriented towards the root and stem position of the crop.

[0047] The root irrigation assembly 5 also includes a connecting block 1 505 fixedly connected to the inner wall of the discharge pipe 303, a connecting block 2 506 fixedly connected to the inner wall of the telescopic tube 2 501, a telescopic spring 3 507 fixedly connected to the top of the connecting block 2 506, and an end of the telescopic spring 3 507 at the outer wall away from the connecting block 2 506 is fixedly connected to the bottom of the connecting block 1 505. By utilizing the characteristic that the water and fertilizer will push the telescopic tube 2 501 to move downward after entering the discharge pipe 303, a plurality of nozzles 502 are arranged. After the water and fertilizer flow into the discharge pipe 303 through the telescopic tube 1 302, the telescopic tube 2 501 will be pushed downward. When the telescopic tube 2 501 moves downward, the roller 504 is driven to move downward synchronously through the connecting rod 503 until the roller 504 contacts the ground, so that The general direction of the nozzle 502 is the root and stem position of the crop. At the same time, when the water and fertilizer push 501 to move, they will also enter the telescopic tube 2 501, and then be sprayed outward through the nozzle 502, so that the water and fertilizer can be directly irrigated to the root and stem position of the crop, so that the water and fertilizer can irrigate the crop more effectively. After the irrigation is completed, the top of the discharge pipe 303 is closed, and the telescopic tube 2 501 is acted upon by the telescopic spring 3 507 to drive the roller 504 to reset, so as to reduce the overall volume of the equipment and facilitate subsequent movement. In addition, the remaining water and fertilizer can also be discharged. Through the operation of the above components, the root and stem position of the crop can be irrigated more specifically to avoid large-scale irrigation. The effective water and fertilizer obtained by the crop is low, which not only causes waste of water and fertilizer but also increases the overall cost.

[0048] The method for using the water-fertilizer integrated irrigation device comprises the following steps:

[0049] S1: Water and fertilizer modulation: before using the device, first move the device to the required position, add water and fertilizer into the fertilizer mixing barrel 201, then connect the water inlet pipe to the water inlet 204, and start the water and fertilizer control box 202 to modulate water and fertilizer. After the water and fertilizer are processed, disconnect the water inlet pipe;

[0050] S2: Start the equipment: After the processed water and fertilizer come out through the water outlet 206, they will push the telescopic tube 302 to move outward through the water outlet pipe 301. When the telescopic tube 302 moves outward, it will simultaneously drive the discharge pipe 303 to move to a specified distance, and then the water and fertilizer will fall to irrigate the crops within the range.

[0051] A specific application of this embodiment is: before using the device, first move the device to the required position, add water and fertilizer into the fertilizer mixing barrel 201, then connect the water inlet pipe to the water inlet 204, and start the water and fertilizer control box 202 to adjust the water and fertilizer. After the water and fertilizer are processed, disconnect the water inlet pipe. After the processed water and fertilizer come out through the water outlet 206, they will push the telescopic tube 1 302 to move outward through the water outlet pipe 301. When the telescopic tube 1 302 moves outward, it will synchronously drive the discharge pipe 303 to move, so that it moves to a specified distance, and then the water and fertilizer fall to irrigate the crops within the range. In addition, when the telescopic tube 1 302 moves outward, the pull rope 309 and the pulley 30 5, the rotating plate 308 can be pulled to rotate with the rotating shaft 307 as the axis. Then, after the water and fertilizer are used up or the water and fertilizer delivery is stopped, the telescopic tube 302 is no longer subjected to the thrust of the water and fertilizer. Under the action of the counterweight block 310 and the arc spring 311, the telescopic tube 302 is pulled to reset through the rotating plate 308 and the pull rope 309. Through the operation of the above components, when water and fertilizer are irrigated, the discharge pipe 303 can be automatically adjusted to the specified position to irrigate the crops. At the end of irrigation, it can be automatically recovered to facilitate the normal movement of the equipment when it is not used for irrigation, avoiding the difficulty of moving the equipment due to the excessive length of the fixed irrigation pipe. At the same time, through the pulley 305, the rotating plate 308 and the pull rope 309 can also form a protective support for the telescopic tube 302 to prevent the telescopic tube 302 from being bent or damaged due to excessive pressure on the telescopic tube 302 due to its excessive movement and the presence of water and fertilizer inside, thereby affecting its normal telescopic movement. When the telescopic tube 302 is pushed outward by the water and fertilizer, the pull rope 309 and the pulley 305 can pull the rotating plate 308 to rotate around the rotating shaft 307. When the rotating plate 308 rotates upward, several pull ropes 309 can move together. When the telescopic tube 302 is moving, when a certain section of the telescopic tube 302 moves longer, the pull ropes 309 on the remaining sections of the telescopic tube 302 will be in a loose position. state, and at this time the water and fertilizer will give priority to pushing these sections of the telescopic tube 302 to keep a relatively equal distance with another section of the telescopic tube 302. At the same time, when the rotating plate 308 is rotated downward by the counterweight block 310 and the arc spring 311, each section of the telescopic tube 302 can also be pulled to move synchronously through the rotating plate 308 and the pull rope 309. Through the operation of the above components, it is avoided that when the telescopic tube 302 moves, the moving distance of each section is uncontrollable, some moving distances are longer, and some moving distances are shorter, resulting in some discharge pipes 303 starting to discharge water and fertilizer, while some have not yet discharged water and fertilizer, causing the equipment to have uneven irrigation when irrigating water and fertilizer, thereby affecting the growth of crops.

[0052] By utilizing the characteristic that the water and fertilizer push the telescopic tube 1 302 to move outward, a sliding partition 401 is provided. When the water and fertilizer push the telescopic tube 1 302 at the rear end to move outward, the sliding partition 401 is synchronously driven to move through the fixed plate 402 and the telescopic spring 1 403, so that the discharge pipe 303 at the rear end is kept in a closed state like the other discharge pipes 303. When the telescopic tube 1 302 continues to move outward, the inclined slider 405 is brought into contact with the groove 407. When the inclined slider 405 is brought into contact with the groove 407, the telescopic spring 2 406 causes the inclined slider 405 to be stuck in the groove 407. At this time, the telescopic tube 1 302 continues to move outward, and the discharge pipe on the telescopic tube 1 302 at the rear end is closed. When the telescopic tube 302 is retracted, due to the design of the inclined surface of the inclined slider 405, the inclined slider 405 will gradually retract and reset, and the telescopic tube 302 will reset at the same time. Through the operation of the above components, the discharge pipe 303 at the rearmost telescopic tube 302 can be opened and closed together with the rest of the discharge pipes 303, so as to avoid the water and fertilizer from flowing out from the rearmost discharge pipe 303 when the telescopic tube 302 is moving, which not only affects the uniformity of irrigation, but also causes waste of water and fertilizer and affects the speed of the telescopic tube 302 moving outward, thereby reducing work efficiency.

[0053] By utilizing the characteristic that the water and fertilizer will push the telescopic tube 2 501 to move downward after entering the discharge tube 303, a plurality of nozzles 502 are arranged. After the water and fertilizer flow into the discharge tube 303 through the telescopic tube 1 302, the telescopic tube 2 501 will be pushed downward. When the telescopic tube 2 501 moves downward, the roller 504 is driven to move downward synchronously through the connecting rod 503 until the roller 504 contacts the ground, so that the nozzle 502 is roughly oriented to the root and stem position of the crop. At the same time, when pushing 501 to move, the water and fertilizer will also enter the telescopic tube 2 501, and then be sprayed outward through the nozzle 502, so that Water and fertilizer can be directly irrigated to the root and stem of the crop, so that the water and fertilizer can irrigate the crop more effectively. After the irrigation is completed, the top of the discharge pipe 303 is closed, and the telescopic tube 2 501 is acted upon by the telescopic spring 3 507 to drive the roller 504 to reset, so as to reduce the overall volume of the equipment and facilitate subsequent movement. In addition, the remaining water and fertilizer can be discharged. Through the operation of the above components, the root and stem of the crop can be irrigated in a more targeted manner, avoiding large-scale irrigation. The effective water and fertilizer obtained by the crop is low, which not only causes waste of water and fertilizer but also increases the overall cost.
