[0032] A plurality of intermittently opened and closed water replenishment holes 101 are provided on the outer wall of the column water distribution tank 1 .

[0033] The water distribution and diversion assembly 2 includes a vertical diversion pipe 201 threadedly matched with the column water distribution box 1, a water pressure piston is fixedly arranged at the bottom of the vertical diversion pipe 201, a limited position groove 202 is provided on the side of the vertical diversion pipe 201, a column diversion box 203 coaxial with the column water distribution box 1 is arranged above the column water distribution box 1, the top of the vertical diversion pipe 201 extends to the inside of the column diversion box 203 and the two are slidably matched, a U-shaped diversion pipe 204 is fixedly arranged on the side of the column diversion box 203 close to the bottom, and one end of the U-shaped diversion pipe 204 is fixedly arranged on the side of the column mixing box 3 close to the At the top position; when the vertical flow guide pipe 201 is controlled to rotate, the threaded cooperation between the vertical flow guide pipe 201 and the column water distribution box 1 is utilized to make the vertical flow guide pipe 201 gradually move downward. In this process, the water in the column water distribution box 1 is squeezed by the water pressure piston. Under the action of the squeezing force, the water in the column water distribution box 1 flows up along the vertical flow guide pipe 201 to the column flow guide box 203, and then flows by itself through the U-shaped flow guide pipe 204 to the column mixing box 3, thereby the quantitative water in the column water distribution tank 1 can be transported to the column mixing box 3 for dissolving the fertilizer.

[0034] A support frame 8 is fixedly installed on the outer wall of the column mixing box 3, and the support frame 8 is fixedly connected to the column water distribution box 1. A discharge pipe head 301 connected to the column mixing box 3 is fixedly arranged at the bottom of the column mixing box 3, and a first solenoid valve 302 is installed on the discharge pipe head 301. After the fertilizer and water are mixed and dissolved inside the column mixing box 3, the first solenoid valve 302 is opened by the controller so that the water and fertilizer in the column mixing box 3 are discharged along the discharge pipe head 301; the rotating mixing part includes a first rotating shaft 303 rotatably connected to the column mixing box 3, a first gear 304 is fixedly arranged on the top of the first rotating shaft 303, and mixing leaves located inside the column mixing box 3 are fixedly arranged on the peripheral side of the first rotating shaft 303. During the water and fertilizer configuration process, the reciprocating rotation of the mixing leaves realizes the continuous stirring of the raw materials inside the column mixing box 3.

[0035] The transmission assembly 4 includes a first mounting frame 401 fixedly arranged on the top of the column water distribution tank 1, a transmission sleeve 402 is rotatably arranged on the top of the first mounting frame 401, a transmission gear 403 coaxial with the transmission sleeve 402 is fixedly arranged on the side surface thereof, a limiting protrusion 404 is fixedly arranged on the inner wall of the transmission sleeve 402, the transmission sleeve 402 is slidably sleeved on the vertical flow guide pipe 201, the limiting protrusion 404 is slidably matched inside the corresponding limiting groove 202, a first transmission rack 405 meshing with the transmission gear 403 is arranged on one side thereof, and a second transmission rack 406 meshing with the first gear 304 is fixedly arranged on the top of the first transmission rack 405; through the above-mentioned specific structural design, when controlling the first transmission rack 405 to move closer to the column mixing box 3 When the cylinder 402 moves horizontally in the direction of rotation, the first transmission rack 405 is used to drive the transmission gear 403 to rotate, and the transmission sleeve 402 that rotates synchronously with the transmission gear 403 drives the vertical flow guide pipe 201 to rotate synchronously, so that the water pressure piston moves downward to squeeze the water in the column water distribution box 1, and the quantitative water is delivered to the column mixing box 3 under the action of the squeezing force. In this process, the first gear 304 is driven to rotate by the horizontal movement of the second transmission rack 406, thereby driving the mixing blades on the first rotating shaft 303 to rotate in the column mixing box 3. During the rotation of the mixing blades, the water in the column mixing box 3 generates a vortex water flow, so that the fertilizer delivered to the column mixing box 3 can be quickly dissolved, thereby greatly improving the rate of water and fertilizer configuration.

[0036] The fertilizer storage component 5 includes a horizontal guide pipe 501 fixedly arranged on the side surface of the cylindrical mixing box 3, and the fertilizer storage box 502 is fixedly connected to the horizontal guide pipe 501 through a discharge pipe 503; the rotating discharge part includes a second rotating shaft 504 rotatably connected to the fertilizer storage box 502, and a second gear 505 is fixedly arranged on the top of the second rotating shaft 504, and an auger component located inside the discharge pipe 503 is fixedly arranged on the side surface of the second rotating shaft 504. When the second gear 505 is controlled to rotate, the auger component can be driven to rotate by the rotation of the second rotating shaft 504, thereby the granular fertilizer in the fertilizer storage box 502 can be transported to the horizontal guide pipe 501 along the discharge pipe 503.

[0037] The unloading control assembly 6 includes a second mounting frame 602 slidably arranged on the top of the fertilizer storage box 502, an unloading control motor 603 and an unloading control gear plate 601 for controlling the rotation of the rotating unloading part are fixedly installed on one side of the second mounting frame 602, the output shaft of the unloading control motor 603 is connected with a third gear 604, an inner gear ring 605 is rotatably arranged on the inner side of the second mounting frame 602, the third gear 604 is arranged on the inner side of the inner gear ring 605 and the two are meshed, and the unloading control gear plate 601 is fixedly connected to the inner gear ring 605 through a support rod 606; when the first transmission rack 405 is controlled to move horizontally in the direction close to the column mixing box 3, the quantitative water distribution is transported to the column mixing box 3 under the action of the extrusion force, and in this process, the water in the column mixing box 3 generates a vortex water flow through the rotation of the mixing blades, and at the same time moves horizontally synchronously with the first transmission rack 405. The moving feeding control tooth plate 601 drives the second gear 505 to rotate, thereby causing the quantitative fertilizer in the fertilizer storage box 502 to fall into the horizontal guide tube 501. When the feeding control tooth plate 601 moves to disengage from the second gear 505, the auger component on the second rotating shaft 504 no longer rotates. At this time, the quantitative fertilizer is transported into the horizontal guide tube 501. Then the feeding control motor 603 is controlled to start running to make the third gear 604 rotate 90°. The third gear 604 is used to drive the inner gear ring 605 to rotate synchronously, thereby rotating the feeding control tooth plate 601 to an upward position. During the process of controlling the feeding control component 6 to move in the opposite direction and reset, the feeding control tooth plate 601 will no longer drive the rotation of the second gear 505, that is, it will no longer cause a certain amount of fertilizer to fall into the horizontal guide tube 501, thereby achieving effective control of the feeding amount in the feeding pipe 503.

[0038] The water-fertilizer configuration control assembly 7 includes a push piston 701 that is slidably fitted inside the horizontal material guide tube 501 and can be elastically reset, a first air storage chamber 703, and a second air storage chamber 704; a closed elastic cover 702 located in the horizontal material guide tube 501 is fitted on one side of the push piston 701; the first air storage chamber 703 is arranged on a side close to the closed elastic cover 702 and the two are arranged coaxially, and the first air storage chamber 703 is connected to the closed elastic cover 702; the second air storage chamber 704 is arranged on a side away from the closed elastic cover 702 and the two are arranged coaxially, the second air storage chamber 704 is connected to the first air storage chamber 703 through a gas delivery pipe 705, and an elastically resettable pneumatic piston 706 is slidably arranged inside the second air storage chamber 704.

[0039] The third mounting frame 707 is horizontally slidably matched with the column mixing box 3, one end of the third mounting frame 707 extends to the inside of the horizontal guide tube 501 and is fixedly connected to the push piston 701, and a first elastic member 708 is arranged between the third mounting frame 707 and the column mixing box 3. The first elastic member 708 is in a natural state in the initial state, the push piston 701 is close to the position of the first air storage chamber 703, and the closed elastic cover 702 is inside the first air storage chamber 703. When the first transmission rack 405 is controlled to move horizontally in the direction close to the column mixing box 3, the quantitative water distribution is delivered to the column mixing box under the action of the extrusion force. 3, during this process, the water in the column mixing box 3 generates a vortex water flow through the rotating motion of the mixing blades, and at the same time, the unloading control tooth plate 601 that moves horizontally synchronously with the first transmission rack 405 drives the second gear 505 to rotate, thereby causing the quantitative fertilizer in the fertilizer storage box 502 to fall into the horizontal guide pipe 501, and when the pushing piston 701 is controlled to move horizontally in the direction close to the column mixing box 3, the fertilizer in the horizontal guide pipe 501 is pushed into the column mixing box 3 by the pushing piston 701, and the granular fertilizer that falls into the column mixing box 3 is mixed with the vortex water flow to achieve rapid dissolution;

[0040] The end of the sealed elastic cover 702 away from the push piston 701 is fixedly provided with a flange 709, and the flange 709 is connected to the horizontal guide pipe 501 by fasteners. A hollow air control box 710 is fixedly provided on the surface of the flange 709, and a partition plate 711 is fixedly provided inside the hollow air control box 710. The first air storage chamber 703 and the second air storage chamber 704 are respectively arranged on both sides of the partition plate 711. The surface of the pneumatic piston 706 is fixedly provided with a first hollow air control box 710 that slides with the hollow air control box 710. Linkage rod 712; gas delivery pipe 705 is fixedly mounted on the side of the central air control box 710, a second solenoid valve 713 is mounted on the gas delivery pipe 705, a pressure relief pipe head 714 and a pressure boost pipe head 715 are respectively fixedly mounted on the side of the central air control box 710, the pressure relief pipe head 714 is connected to the first gas storage chamber 703 and a third solenoid valve 716 is mounted on the pressure relief pipe head 714, the pressure boost pipe head 715 is connected to the second gas storage chamber 704 and a one-way valve 717 is mounted on the pressure boost pipe head 715;

[0041] The first linkage rod 712 is fixedly provided with a fourth mounting bracket 718 located outside the hollow air control box 710 on the side thereof, a second linkage rod 719 is fixedly provided on one side of the fourth mounting bracket 718, the first transmission rack 405 is fixedly sleeved on the second linkage rod 719, a special-shaped connecting plate 720 is fixedly provided on the side thereof, the second mounting bracket 602 is fixedly connected to the special-shaped connecting plate 720, and the mounting plate 721 fixed on the side of the hollow air control box 710 is connected to the fourth mounting bracket 718. The second air storage chamber 704 is connected by a second elastic member 722; a set of gas boosting equipment is installed on the external frame, and multiple exhaust pipes on the gas boosting equipment are connected to the corresponding boosting pipe head 715. After the gas boosting equipment is started, air is input into each second air storage chamber 704, so that the air pressure inside each second air storage chamber 704 increases, and the air pressure pushes the pneumatic piston 706 to move away from the partition plate 711 until the pneumatic piston 706 abuts against the first air storage chamber 703 away from the partition plate 711. The fourth mounting frame 718 which moves synchronously with the first linkage rod 712 drives the second linkage rod 719 and the special-shaped connecting plate 720 to move synchronously. The second linkage rod 719 which moves horizontally drives the first transmission rack 405 and the second transmission rack 406 to move toward the fertilizer storage box 502, thereby realizing the simultaneous driving of the transmission gear 403 and the first gear 304. At the same time, the horizontal movement of the special-shaped connecting plate 720 drives the unloading control assembly 6 to move together, and the unloading control tooth plate 601 drives the second gear 505 to rotate. In this process, the closed elastic cover 702 is always inside the first air storage chamber 703. At this time, the unloading control tooth plate 601 is horizontally separated from the second gear 505. Then, the unloading control motor 603 is started to drive the third gear 604 to rotate 90°, and the third gear 604 is used to drive the inner gear ring 605 to rotate synchronously, thereby rotating the unloading control tooth plate 601 to the upward position.

[0042] Then, the controller controls the second solenoid valve 713 to open. Under the strong elastic restoring force of the second elastic member 722, the first linkage rod 712 moves in the opposite direction to drive the pneumatic piston 706 to move in the opposite direction to reset. During the reset process, the pneumatic piston 706 is used to press the air in the second air storage chamber 704 into the first air storage chamber 703 along the gas delivery pipe 705, so that the air pressure in the first air storage chamber 703 gradually increases. Under the action of the gradually increasing air pressure, the closed elastic cover 702 in the first air storage chamber 703 is driven to move outward until the closed elastic cover 702 is closed. The cover 702 is completely moved into the horizontal guide tube 501. During this process, the sealed elastic cover 702 is used to push the push piston 701 to move horizontally toward the column mixing box 3. The push piston 701 moves horizontally in the horizontal guide tube 501 to completely push the granular fertilizer falling into the horizontal guide tube 501 into the column mixing box 3. The third mounting frame 707 that moves synchronously with the push piston 701 gradually stretches the first elastic member 708, and then the controller controls the second solenoid valve 713 to close, and the pneumatic piston 706 completes the reset.

[0043] After the granular fertilizer that has fallen into the horizontal guide tube 501 is completely pushed into the column mixing box 3, the controller controls the third solenoid valve 716 to open to achieve pressure relief inside the first air storage chamber 703. During the pressure relief process, with the help of the elastic restoring force of the first elastic member 708 and the pressure relief inside the first air storage chamber 703, the closed elastic cover 702 retracts into the first air storage chamber 703, and the pushing piston 701 also returns to its initial position. Finally, the controller controls the third solenoid valve 716 to close.

[0044] The irrigation control assembly 9 includes a water supply box 901, and a plurality of columnar mounting cavities 902 are provided on the outer wall of the water supply box 901. The columnar water distribution box 1 is fixedly installed inside the corresponding columnar mounting cavity 902, and a first flow port 903 communicating with the inside of the water supply box 901 is provided inside the columnar mounting cavity 902; the output shaft of the water supply control motor 904 fixedly installed at the bottom of the water supply box 901 is connected to a connecting frame 905 located inside the water supply box 901, and a closed ring 906 provided inside the water supply box 901 is attached to its inner wall, and the connecting frame 905 is fixedly provided inside the closed ring 906, and a second flow port 907 corresponding to the first flow port 903 is provided on the side surface of the closed ring 906. Only when the second flow port 907 is aligned with the first flow port 903, can the water in the water supply box 901 flow into the columnar water distribution box 1 through the second flow port 907 and the first flow port 903 in turn.

[0045] The water supply box 901 is fixedly installed on the external frame and a pouring box 908 is arranged below it, and a plurality of pouring holes are provided at the bottom thereof. The pouring box 908 is connected to the water supply box 901 by a fixed plate, and the pouring box 908 and each drainage pipe head 301 on its surrounding side are connected by a confluence pipe, one end of the confluence pipe is connected to the top of the pouring box 908, and a booster pump 909 is fixedly installed on the top of the pouring box 908. After completing the configuration of water and fertilizer in each column mixing box 3, each first solenoid valve 302 is controlled to be opened by a controller at the same time, and the water and fertilizer in each column mixing box 3 flows downward along the confluence pipe into the inside of the pouring box 908. When the water and fertilizer in each column mixing box 3 are discharged into the pouring box 908, Close each first solenoid valve 302, and start the water supply control motor 904 to drive the closed ring 906 to rotate, so that each second flow port 907 is realigned with the corresponding first flow port 903. At this time, the water in the water supply box 901 flows into the column water distribution tank 1 through the second flow port 907, the first flow port 903 and the water replenishment hole 101 in turn. After completing the water replenishment in each column water distribution tank 1, control the closed ring 906 to rotate again so that the second flow port 907 is misaligned with the first flow port 903, so that the column water distribution tank 1 is completely isolated from the irrigation box 908, and then start the booster pump 909 to increase the pressure inside the irrigation box 908, thereby spraying the mixed water and fertilizer in the irrigation box 908 to realize the irrigation operation.

[0046] Working process: control the first transmission rack 405 to move horizontally in the direction close to the column mixing box 3, and under the action of the extrusion force, the quantitative water is transported to the column mixing box 3, and the water in the column mixing box 3 generates a vortex water flow through the rotating movement of the mixing blades. At the same time, the unloading control tooth plate 601 that moves horizontally synchronously with the first transmission rack 405 drives the second gear 505 to rotate, so that the quantitative fertilizer in the fertilizer storage box 502 falls into the horizontal guide tube 501. When the unloading control tooth plate 601 moves to disengage from the second gear 505, the auger component on the second rotating shaft 504 no longer rotates, and the quantitative fertilizer is transported to the horizontal guide tube 501 at this time. Then control the unloading control motor 603 to start running so that the third gear 604 rotates 90°, and the third gear 604 drives the inner gear ring 605 to rotate synchronously, thereby rotating the unloading control tooth plate 601 to the upward position, and then controlling the unloading control component 6 to reverse During the reset process of movement, the feeding control tooth plate 601 will no longer drive the rotation of the second gear 505, and will not cause a certain amount of fertilizer to fall into the horizontal guide pipe 501. The effective control of the feeding amount in the feeding pipe 501 is realized, and the first transmission rack 405 is used to drive the transmission gear 403 to rotate, and the transmission sleeve 402 that rotates synchronously with the transmission gear 403 drives the vertical guide pipe 201 to rotate synchronously, so that the water pressure piston moves downward to squeeze the water in the column water distribution box 1, and under the action of the squeezing force, the quantitative water is delivered to the column mixing box 3, and the horizontal movement of the second transmission rack 406 drives the first gear 304 to rotate, driving the mixing blades on the first rotating shaft 303 to rotate in the column mixing box 3. During the rotation of the mixing blades, the water in the column mixing box 3 generates a vortex water flow, so that the fertilizer delivered to the column mixing box 3 can be quickly dissolved, thereby increasing the rate of water and fertilizer configuration.

[0047] After the water and fertilizer configuration in each column mixing box 3 is completed, each first solenoid valve 302 is controlled to be opened by the controller at the same time, and the water and fertilizer in each column mixing box 3 flows downward along the confluence pipe into the inside of the irrigation box 908. When the water and fertilizer in each column mixing box 3 are discharged into the irrigation box 908, each first solenoid valve 302 is closed, and the water supply control motor 904 is started at the same time to drive the closed ring 906 to rotate, so that each second flow port 907 is realigned with the corresponding first flow port 903. At this time, the water supply box The water in the body 901 flows into the column water distribution box 1 through the second flow port 907, the first flow port 903 and the water replenishment hole 101 in turn. After the water replenishment in each column water distribution box 1 is completed, the closed ring 906 is controlled to rotate again to make the second flow port 907 and the first flow port 903 misaligned, so that the column water distribution box 1 is completely isolated from the irrigation box 908, and then the booster pump 909 is started to increase the pressure inside the irrigation box 908, thereby spraying the mixed water and fertilizer in the irrigation box 908 to realize the irrigation operation.
