Description

Technical Field

[0001] The invention relates to the technical field of integrated water and fertilizer machines, and in particular to an under-film drip irrigation type integrated water and fertilizer machine. Background Art

[0002] The integrated water-fertilizer equipment uses a pressure system to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of crops. The fertilizer solution is mixed with irrigation water and then dripped through a controllable pipeline system to form drip irrigation, which evenly, regularly and quantitatively infiltrates the crop root development and growth area, so that the main root soil always remains loose and has an appropriate moisture content.

[0003] At present, a water-fertilizer integrated machine is needed for drip irrigation under film for some crops. Specifically, the fertilizer is put into a mixing barrel, and the fertilizer and water are mixed through the agitator inside the mixing barrel. Then the water and fertilizer will be drip-irrigated to the crops under the film through the drip irrigation pipe. However, after the fertilizer is put into the mixing barrel and the water and fertilizer in the barrel are emptied, some fertilizer residues will adhere to the stirring device in the mixing barrel. When different fertilizers are put in next time, the new fertilizer will chemically react with the residual fertilizer, affecting the fertilizer efficiency.

[0004] On the other hand, a smart water-fertilizer integrated machine that is easy to disassemble and assemble is disclosed in the Chinese invention patent application disclosure specification CN114766166B. The water storage barrel and frame in the device no longer need to be opened manually after installation, which is convenient for the discharge and use of the water-fertilizer integrated machine. However, it is difficult for the above device to break up the agglomerated fertilizer, so that the agglomerated fertilizer is difficult to dissolve quickly in water. Traditional solid fertilizers are generally stirred with spiral blades when mixed with water. However, due to temperature, humidity, and stacking pressure, solid fertilizers are prone to agglomeration or condensation. Simple mixing and stirring is difficult to make the agglomerated fertilizer dissolve quickly in water. At the same time, the solid fertilizer will sink to the bottom of the mixing barrel, and the contact area between the fertilizer and water is small, which makes the mixing efficiency of water and fertilizer low, greatly increases the mixing time of water and fertilizer, and thus affects the subsequent drip irrigation operation. Therefore, we propose a sub-membrane drip irrigation water-fertilizer integrated machine to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the shortcomings of the prior art and propose a sub-membrane drip irrigation water-fertilizer integrated machine. The device has the advantages of breaking up agglomerated fertilizers so that the agglomerated fertilizers can be quickly dissolved in water. It also has the advantages of increasing the contact area between fertilizers and water to improve mixing efficiency. On the other hand, the device can perform self-cleaning in the barrel to avoid the problem of cross-contamination of residual fertilizers.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a sub-membrane drip irrigation type water-fertilizer integrated machine, comprising a mixing barrel, a driving mechanism is arranged above the mixing barrel, the driving mechanism comprises a ring rail, the ring rail is fixed to the mixing barrel, the inner wall of the ring rail is rotatably connected with a rotating disk, a motor is fixed to the outer surface of the mixing barrel, the output end of the motor is transmission-connected to the rotating disk through a belt and a pulley, a plurality of sprinkler heads are installed on the inner top wall of the mixing barrel, a filter barrel is arranged inside the mixing barrel, three water spraying mechanisms in a circular array are arranged above the filter barrel, the water spraying mechanism comprises a water pipe, the bottom end of the water pipe passes through the filter barrel and is rotatably connected to the filter barrel, and the water pipe is slidably connected to the rotating disk.

[0007] A triangular prism is fixedly connected to the inner wall of the filter cartridge, and three crushing mechanisms in a circular array are arranged on the outside of the filter cartridge, and the crushing mechanism includes a fixed tube, a threaded slide and a square rod. A sliding frame is fixed to the outer surface of the fixed tube, and the threaded slide is fixed to the inner wall of the mixing tube. The sliding frame is slidably connected to the threaded slide, and a plurality of top pressure blocks matched with the square rod are fixed to the outer surface of the threaded slide. The square rod penetrates the fixed tube and is slidably connected to the fixed tube, and the square rod is slidably connected to the filter cartridge, and a crushing arc plate is fixed to one end of the square rod, and the crushing arc plate is located inside the filter cartridge, and a fixed plate is arranged on the side of the crushing arc plate away from the triangular prism, and the fixed plate is fixed to the inner wall of the filter cartridge, and the square rod is slidably connected to the fixed plate.

[0008] Furthermore, the driving mechanism also includes a water inlet pipe, the bottom end of the water inlet pipe is sealingly rotatably connected to a diverter, the top end of the water pipe is sealingly rotatably connected to the diverter, a plurality of stirring rods are fixed to the outer surface of the water pipe, a plurality of nozzles are installed on the outer surface of the water pipe, and each stirring rod and nozzle are located inside the filter cartridge.

[0009] By adopting the above technical solution, the external water source is controlled to flow into the water inlet pipe. The water in the water inlet pipe is diverted to three water pipes through a diverter. The water in the water pipes is sprayed out through a nozzle and passed through a filter cylinder and injected into a mixing cylinder. When the mixing cylinder is full of water, the water supply from the water inlet pipe is stopped.

[0010] Furthermore, the driving mechanism also includes a limiting ring, a tripod is fixed to the outer surface of the water inlet pipe, the tripod is fixed to the limiting ring, three sliding blocks are fixed to the outer surface of the tripod, three limiting rods are fixed to the outer surface of the mixing barrel, the three sliding blocks are slidably connected to the three limiting rods respectively, an inner gear ring is fixed to the inner wall of the limiting ring, a sliding block is rotatably connected to the outer surface of the water pipe, the sliding block is slidably connected to the limiting ring, a gear is fixed to the outer surface of the water pipe, and the gear is meshed with the inner gear ring.

[0011] By adopting the above technical solution, since the gear is meshed with the inner gear ring, when the rotating disk drives the three water pipes to rotate, the gear will drive the water pipes to rotate, and the nozzles on the water pipes will rotate to spray out clean water, and the stirring rod on the water pipe will continuously stir to accelerate the fusion of fertilizer and water in the filter cartridge.

[0012] Furthermore, three feeding mechanisms are arranged above the filter cartridge, and the feeding mechanism includes a feeding pipe, which is fixedly connected to the filter cartridge, a long tube is fixed to the outer surface of the feeding pipe, and both the feeding pipe and the long tube are slidably connected to the rotating disk, a long rod is rotatably connected to the inner wall of the long tube, a worm is fixed to the outer surface of the long rod, the inner wall of the feeding pipe is rotatably connected to the rotating rod, a worm wheel is fixed to the middle part of the rotating rod, the worm wheel is meshed with the worm, a baffle plate is fixed to the outer surface of the rotating rod, and a blocking block adapted to the baffle plate is fixed to the inner wall of the feeding pipe.

[0013] By adopting the above technical solution, when in use, the fertilizer is first fed into the filter cartridge through three feeding pipes, and the long rod is rotated to drive the baffle plate to flip through the engagement of the worm and the worm gear, so that the baffle plate blocks the feeding pipe to prevent the solid fertilizer in the filter cartridge from flowing back into the feeding pipe.

[0014] A sliding plate is fixed on the outer surface of the square rod, and the sliding plate is slidably connected to the inner wall of the fixed tube. A telescopic spring is sleeved on the outer surface of the square rod, and the two ends of the telescopic spring are respectively fixed to the sliding plate and the fixed tube. A rotating cylinder is rotatably connected to the outer surface of the fixed tube, and three oblique arc grooves are fixed on the outer surface of the rotating cylinder.

[0015] By adopting the above technical scheme, when the sliding frame slides along the threaded slide bar, the pressing block on the threaded slide bar will press the square rod, so that the square rod drives the crushing arc plate to approach the triangular prism. After the square rod is no longer pressed, it is reset by the spring force of the telescopic spring 1, so that the crushing arc plate will move back and forth in the filter cartridge. When the agglomerated fertilizer passes between the triangular prism and the crushing arc plate or between the crushing arc plate and the fixed plate, the agglomerated fertilizer will be crushed by the crushing arc plate, and the contact area between the crushed fertilizer and water is increased, thereby improving the mixing efficiency of the fertilizer and water.

[0016] An extrusion strip is fixed on the outer surface of the square rod, and the extrusion strip is slidably connected to the sliding frame. Two square tubes are fixed on the outer surface of the sliding frame. The inner walls of the two square tubes are slidably connected to pressure columns. The two pressure columns are fixed with sliding rods at one end away from the extrusion strip. The outer surface of the rotating cylinder is provided with two stirring rods 2 that are compatible with the sliding rods. The two stirring rods 2 are slidably connected to the two sliding rods respectively. The two pressure columns are fixed with baffles at one end close to the extrusion strip, and the outer surfaces of the two baffles are fixed with two telescopic springs. The two telescopic springs 2 are respectively fixed to the two square tubes.

[0017] By adopting the above technical solution, while the pressing block on the threaded sliding bar will press the square rod, the extrusion bar on the square rod will press the pressure column, so that the sliding bar on the pressure column will move, and the sliding bar will drive the rotating drum to rotate through the stirring rod 2. The three inclined arc grooves on the rotating drum will stir the fertilizer and water in the mixing drum, thereby accelerating the uniform mixing of the fertilizer and water in the mixing drum and improving the mixing efficiency.

[0018] Furthermore, a quick-release mechanism is provided below the mixing barrel, and the quick-release mechanism includes a bucket-shaped tube, the bucket-shaped tube is fixedly connected to the mixing barrel, the bottom end of the bucket-shaped tube is fixedly connected to a fixing box, the bottom surface of the fixing box is fixedly connected to a drip irrigation pipe, the inner wall of the fixing box is sealingly and slidably connected to a sealing plate, and the inner wall of the sealing plate is fixed with a filter plate.

[0019] By adopting the above technical solution and setting the filter plate, large particle impurities in the mixing cylinder can be filtered to prevent the large particle impurities from clogging the drip irrigation port of the drip irrigation pipe.

[0020] Furthermore, a sleeve is fixed on the outer surface of the sealing plate, a circular plate is slidably connected to the inner wall of the sleeve, a latch is fixed on the upper surface of the circular plate, a limiting tube matched with the latch is fixed on the outer surface of the fixed box, a pull rod is fixed on the bottom surface of the circular plate, a telescopic spring three is sleeved on the outer surface of the pull rod, and both ends of the telescopic spring three are respectively fixed to the circular plate and the sleeve.

[0021] By adopting the above technical solution, when the filter plate needs to be cleaned, the pull rod is pulled to drive the pin away from the limiting tube, so that the sealing plate can be slid in the fixed box and the filter plate is moved to the outside of the fixed box, making it convenient for personnel to clean the filter plate.

[0022] Compared with the existing technology, the sub-membrane drip irrigation water and fertilizer integrated machine has the following beneficial effects: 1. The present invention is provided with a filter cartridge, a crushing mechanism and a triangular prism. After the fertilizer is put into the filter cartridge, the sliding frame slides along the threaded slide bar, so that the filter cartridge rotates and moves up and down in the mixing barrel. At the same time, the crushing arc plate moves back and forth in the filter cartridge, so that the agglomerated fertilizer between the triangular prism and the crushing arc plate and between the crushing arc plate and the fixed plate is crushed, and the contact area between the crushed fertilizer and water is increased, thereby improving the mixing efficiency of the fertilizer and water.

[0023] 2. The present invention is provided with a filter cartridge, a water spraying mechanism and a crushing mechanism. When the filter cartridge moves up and down in the mixing barrel, the three water pipes in the filter cartridge rotate, and the nozzle on each water pipe rotates to spray clean water, and continuously stirs through the stirring rod on the water pipe to accelerate the blending of the fertilizer and water in the filter cartridge. At the same time, when the sliding frame slides along the threaded sliding strip, the rotating barrel will drive the oblique arc groove thereon to rotate, and accelerate the uniform mixing of the fertilizer and water in the mixing barrel. Therefore, this multi-directional and multi-directional stirring method can not only improve the mixing efficiency but also make the fertilizer and water mixing more uniform.

[0024] 3. The present invention is provided with a driving mechanism and a water spraying mechanism. After the fertilizer water in the mixing barrel is emptied, the filter barrel is rotated. Since the gear on the water pipe is meshed with the inner gear ring, the nozzle on the water pipe rotates and sprays clean water to wash the parts in the filter barrel at multiple angles. At the same time, the spray head on the top wall of the mixing barrel is controlled to spray water to wash the parts in the mixing barrel, thereby avoiding residual fertilizer in the mixing barrel. Therefore, the problem of cross-contamination of residual fertilizer can be avoided through the self-cleaning method in the barrel.

[0025] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0030] The motor 309 is started, and the motor 309 drives the rotating disk 308 to rotate through the belt and the pulley, and the rotating disk 308 drives the filter cartridge 2 to rotate through the three water pipes 501, thereby providing a power source for the rotation of the filter cartridge 2. The multiple spray heads on the inner top wall of the mixing cylinder 1 can spray and rinse the inside of the mixing cylinder 1, but this technology is relatively common in the field of spray technology and is not the inventive point of the present invention, so it will not be described in detail.

[0031] Please refer to Figure 4 , Figure 5 and Figure 7 The driving mechanism 3 further comprises a water inlet pipe 301, the bottom end of the water inlet pipe 301 is sealed and rotatably connected with a diverter 302, the top end of the water pipe 501 is sealed and rotatably connected with the diverter 302, a plurality of stirring rods 504 are fixed on the outer surface of the water pipe 501, a plurality of nozzles 505 are installed on the outer surface of the water pipe 501, and each stirring rod 504 and nozzle 505 are located inside the filter cartridge 2.

[0032] Please refer to Figure 7 , Fig. 9 and Fig.10The driving mechanism 3 also includes a limiting ring 306. A tripod 303 is fixed to the outer surface of the water inlet pipe 301, and the tripod 303 is fixed to the limiting ring 306. Three sliders 304 are fixed to the outer surface of the tripod 303.

The sliding block 502 is slidably connected to the limiting ring 306. A gear 503 is fixed to the outer surface of the water pipe 501, and the gear 503 is meshed with the inner gear ring 307.

[0033] Since the gear 503 is meshed with the inner gear ring 307, when the rotating disk 308 drives the three water pipes 501 to rotate, the gear 503 will drive the water pipes 501 to rotate, and the nozzles 505 on the water pipes 501 will rotate to spray out clean water, and the stirring rod 504 on the water pipes 501 will continuously stir the water to accelerate the mixing of the fertilizer and water in the filter cartridge 2.

[0034] Please refer to Figure 5 and Figure 8 Three feeding mechanisms 4 are arranged above the filter cartridge 2, and the feeding mechanism 4 includes a feeding pipe 401, which is fixedly connected to the filter cartridge 2, a long tube 402 is fixed on the outer surface of the feeding pipe 401, and the feeding pipe 401 and the long tube 402 are both slidably connected to the rotating disk 308, a long rod 403 is rotatably connected to the inner wall of the long tube 402, a worm 404 is fixed on the outer surface of the long rod 403, a rotating rod 405 is rotatably connected to the inner wall of the feeding pipe 401, a worm gear 408 is fixed to the middle part of the rotating rod 405, the worm gear 408 is meshed with the worm 404, a baffle plate 406 is fixed on the outer surface of the rotating rod 405, and a blocking block 407 adapted to the baffle plate 406 is fixed to the inner wall of the feeding pipe 401. When in use, first put the fertilizer into the filter cartridge 2 through the three feeding pipes 401, and rotate the long rod 403 to drive the baffle plate 406 to flip through the engagement of the worm 404 and the worm wheel 408, so that the baffle plate 406 blocks the feeding pipe 401 to prevent the solid fertilizer in the filter cartridge 2 from flowing back into the feeding pipe 401.

[0035] Please refer to Figure 6 and Fig.11The inner wall of the filter cartridge 2 is fixedly connected with a triangular prism 7, and the outside of the filter cartridge 2 is provided with three crushing mechanisms 6 in a circular array, the crushing mechanism 6 includes a fixed tube 601, a threaded slide 603 and a square rod 605, the outer surface of the fixed tube 601 is fixed with a sliding frame 602, the threaded slide 603 is fixed to the inner wall of the mixing barrel 1, the sliding frame 602 is slidably connected with the threaded slide 603, the outer surface of the threaded slide 603 is fixed with a plurality of top pressure blocks 604 adapted to the square rod 605, the square rod 605 penetrates the fixed tube 601 and is slidably connected with the fixed tube 601, the square rod 605 is slidably connected with the filter cartridge 2, a crushing arc plate 606 is fixed at one end of the square rod 605, the crushing arc plate 606 is located inside the filter cartridge 2, a fixed plate 618 is provided on the side of the crushing arc plate 606 away from the triangular prism 7, the fixed plate 618 is fixed to the inner wall of the filter cartridge 2, and the square rod 605 is slidably connected with the fixed plate 618. A plurality of crushing cones are provided on both sides of the crushing arc plate 606. When the crushing arc plate 606 moves, the agglomerated fertilizer between the triangular prism 7 and the crushing arc plate 606 and between the crushing arc plate 606 and the fixed plate 618 is crushed.

[0036] The starting motor 309 drives the rotating disk 308 to rotate, and the rotating disk 308 drives the filter cartridge 2 to rotate through the three water pipes 501 and the three feeding pipes 401. The rotation of the filter cartridge 2 will drive the sliding frame 602 on the fixed tube 601 to slide on the threaded slide bar 603 through the square rod 605. Since the threaded slide bar 603 is threaded as a whole, the filter cartridge 2 rotates and moves downward. When the filter cartridge 2 moves downward to the bottom end, the control motor 309 drives the rotating disk 308 to rotate in the opposite direction, so that the filter cartridge 2 rotates and moves upward, so that the filter cartridge 2 moves back and forth up and down in the mixing barrel 1, and the fertilizer in the filter cartridge 2 will be mixed with water of different depths, so that the fertilizer and water can be mixed more evenly.

[0037] Please refer to Fig.12 , Fig.13 and Fig.14 A sliding plate 607 is fixed to the outer surface of the square rod 605, and the sliding plate 607 is slidably connected to the inner wall of the fixed tube 601. A telescopic spring 608 is sleeved on the outer surface of the square rod 605, and the two ends of the telescopic spring 608 are respectively fixed to the sliding plate 607 and the fixed tube 601. The outer surface of the fixed tube 601 is rotatably connected to a rotating cylinder 615, and three oblique arc grooves 617 are fixed to the outer surface of the rotating cylinder 615.

[0038] When the sliding frame 602 slides along the threaded slide bar 603, the pressing block 604 on the threaded slide bar 603 will press the square rod 605, so that the square rod 605 drives the breaking arc plate 606 to approach the triangular prism 7. After the square rod 605 is no longer pressed, it is reset by the spring force of the telescopic spring 608, so that the breaking arc plate 606 will reciprocate in the filter cartridge 2. When the agglomerated fertilizer passes between the triangular prism 7 and the breaking arc plate 606 or between the breaking arc plate 606 and the fixed plate 618, the agglomerated fertilizer will be broken by the breaking arc plate 606, and the contact area between the crushed fertilizer and water will increase, thereby improving the mixing efficiency of the fertilizer and water.

[0039] Please refer to Fig.12 and Fig.13 An extrusion bar 609 is fixed on the outer surface of the square rod 605, and the extrusion bar 609 is slidably connected to the sliding frame 602.

The outer surfaces of the two baffles 612 are fixed with telescopic springs 613, and the two telescopic springs 613 are respectively fixed to the two square tubes 610.

[0040] While the pressing block 604 on the threaded slide bar 603 presses the square rod 605, the extrusion bar 609 on the square rod 605 presses the pressure column 611, so that the slide bar 614 on the pressure column 611 moves, and the slide bar 614 drives the rotating cylinder 615 to rotate through the stirring rod 2 616. After the pressure column 611 is no longer pressed by the extrusion bar 609, the pressure column 611 is reset by the spring force of the telescopic spring 2 613, so that the slide bar 614 causes the rotating cylinder 615 to rotate in the opposite direction through the stirring rod 2 616. Through multiple forward and reverse rotations of the rotating cylinder 615, the three oblique arc grooves 617 on the rotating cylinder 615 will stir the fertilizer and water in the mixing cylinder 1, accelerate the uniform mixing of the fertilizer and water in the mixing cylinder 1 and improve the mixing efficiency.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3A quick release mechanism 8 is provided below the mixing barrel 1. The quick release mechanism 8 includes a bucket-shaped tube 801. The bucket-shaped tube 801 is fixedly connected to the mixing barrel 1. The bottom end of the bucket-shaped tube 801 is fixedly connected to a fixing box 802.

A filter plate 805 is fixed to the inner wall of the sealing plate 804. An electric valve (not shown in the figure) is provided between the drip irrigation pipe 9 and the fixing box 802. Closing the electric valve prevents the water in the mixing barrel 1 from flowing into the drip irrigation pipe 9. Opening the electric valve allows the water in the mixing barrel 1 to drip irrigate the plants under the film through the drip irrigation pipe 9. The filter plate 805 is provided to filter the large particles of impurities in the mixing barrel 1 to prevent the large particles of impurities from clogging the drip irrigation port of the drip irrigation pipe 9.

[0042] A sleeve 806 is fixed to the outer surface of the sealing plate 804, and a circular plate 808 is slidably connected to the inner wall of the sleeve 806. A latch 809 is fixed to the upper surface of the circular plate 808. A limiting tube 803 matched with the latch 809 is fixed to the outer surface of the fixed box 802. A pull rod 807 is fixed to the bottom surface of the circular plate 808. A telescopic spring three 810 is sleeved on the outer surface of the pull rod 807. The two ends of the telescopic spring three 810 are respectively fixed to the circular plate 808 and the sleeve 806.

[0043] When it is necessary to clean the filter plate 805, pull the pull rod 807 to drive the latch 809 away from the limiting tube 803, so that the sealing plate 804 can slide in the fixing box 802, and the filter plate 805 is moved to the outside of the fixing box 802, which is convenient for personnel to clean the filter plate 805. When installing the filter plate 805, move the sealing plate 804 so that the filter plate 805 is located between the bucket tube 801 and the opening of the drip irrigation pipe 9, and insert the latch 809 into the limiting tube 803 to limit the sealing plate 804. Through the setting of the telescopic spring three 810, the circular plate 808 is subjected to the spring tension of the telescopic spring three 810, so that the latch 809 maintains a clamping state with the limiting tube 803.

[0044] like Figure 1 As shown, a control box 10 is fixedly installed on the outer surface of the mixing barrel 1, and the control box 10 is electrically connected to the motor 309 and the electric valve. The rotation state of the motor 309 and the opening state of the electric valve are controlled by the control box 10 to cater to the implementation spirit of this application and achieve the implementation purpose of this application.

[0045] Working principle: When in use, first put the fertilizer into the filter cartridge 2 through the three feeding pipes 401, and rotate the long rod 403 to drive the baffle plate 406 to flip through the engagement of the worm 404 and the worm wheel 408, so that the baffle plate 406 blocks the feeding pipe 401, controls the external water source to flow into the water inlet pipe 301, and the water in the water inlet pipe 301 is diverted to the three water pipes 501 through the diverter 302. The water in the water pipe 501 is sprayed out through the nozzle 505 and passes through the filter cartridge 2 and is injected into the mixing cylinder 1. When the mixing cylinder 1 is filled with water, the water supply from the water inlet pipe 301 is stopped.

[0046] When water starts to flow through the water inlet pipe 301, the motor 309 is started, so that the motor 309 drives the rotating disk 308 to rotate, and the rotating disk 308 drives the filter cartridge 2 to rotate through the three water pipes 501 and the three feeding pipes 401. The rotation of the filter cartridge 2 will drive the sliding frame 602 on the fixed pipe 601 to slide on the threaded slide bar 603 through the square rod 605. Since the threaded slide bar 603 is a threaded shape as a whole, the filter cartridge 2 rotates and moves downward. When the filter cartridge 2 moves downward to the bottom, the motor 309 is controlled to drive the rotating disk 308 to rotate in the opposite direction, so that the filter cartridge 2 rotates and moves upward, so that the filter cartridge 2 moves back and forth up and down in the mixing barrel 1.

[0047] Since the gear 503 is meshed with the inner gear ring 307, when the rotating disk 308 drives the three water pipes 501 to rotate, the gear 503 will drive the water pipes 501 to rotate, and the nozzles 505 on the water pipes 501 will rotate to spray out clean water, and the stirring rod 504 on the water pipes 501 will continuously stir the water to accelerate the mixing of the fertilizer and water in the filter cartridge 2.

[0048] When the sliding frame 602 slides along the threaded slide bar 603, the pressing block 604 on the threaded slide bar 603 will press the square rod 605, so that the square rod 605 drives the breaking arc plate 606 to approach the triangular prism 7. After the square rod 605 is no longer pressed, it is reset by the spring force of the telescopic spring 608, so that the breaking arc plate 606 will reciprocate in the filter cartridge 2. When the agglomerated fertilizer passes between the triangular prism 7 and the breaking arc plate 606 or between the breaking arc plate 606 and the fixed plate 618, the agglomerated fertilizer will be broken by the breaking arc plate 606, and the contact area between the crushed fertilizer and water will increase, thereby improving the mixing efficiency of the fertilizer and water.

[0049] While the pressing block 604 on the threaded slide bar 603 presses the square rod 605, the extrusion bar 609 on the square rod 605 presses the pressure column 611, so that the slide bar 614 on the pressure column 611 moves, and the slide bar 614 drives the rotating cylinder 615 to rotate through the stirring rod 2 616. The three oblique arc grooves 617 on the rotating cylinder 615 rotate to stir the fertilizer water in the mixing cylinder 1, and accelerate the uniform mixing of the fertilizer and water in the mixing cylinder 1. After the fertilizer in the filter cylinder 2 is completely dissolved in water, the electric valve arranged between the drip irrigation pipe 9 and the fixed box 802 is opened, so that the fertilizer water in the mixing cylinder 1 is drip-irrigated to the plants under the film through the drip irrigation pipe 9.

[0050] After the fertilizer and water in the mixing drum 1 are drained, the motor 309 continues to operate, so that the nozzle 505 on the water pipe 501 rotates and sprays clean water to rinse the parts in the filter drum 2 at multiple angles. At the same time, the sprinkler head on the top wall of the mixing drum 1 is controlled to spray water to rinse the parts in the mixing drum 1. The rinsed water will be drip-irrigated to the plants under the film again through the drip irrigation pipe 9 to avoid waste of fertilizer residue and cross contamination of residual fertilizer in the mixing drum 1.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
