[0014] Compared with the prior art, the present invention has the following advantages: 1. In this application, by providing a mixing box, a mounting cover, a feed pipe, a fixed cover, a support rod, a stirring device, a feed hole, and an irrigation device, water and fertilizer particles can be put into the mixing box through the feed pipe, and then the stirring device stirs them evenly to form water and fertilizer. Under the action of the irrigation device, the evenly stirred water and fertilizer are irrigated into the cotton field, thereby reducing the evaporation of water and fertilizer and reducing the waste of water and fertilizer. 2. In the present application, by providing a servo motor, a connecting rod, a placement slot, an installation slot, a stirring rod, a rubber block, a deformation slot, a bottom plate, a rubber ball, a card slot, a grinding block, a discharge ring, a grinding ring and a discharge slot, the connecting rod can be driven to rotate by the servo motor, and the connecting rod drives the grinding block to rotate in the discharge ring and the grinding ring. At this time, the stirring rod is expanded under the action of centrifugal force, and at the same time, the stirring rod pushes the rubber block to deform under the action of the deformation slot. The water and fertilizer particles in the mixing box are stirred by the expanded stirring rod, so that the fertilizer particles and water are evenly mixed to form water fertilizer. After that, the servo motor is controlled to reduce the speed. At this time, the centrifugal force is reduced, and the rubber block is pushed under the action of its own elastic force. The dynamic stirring rod is reset, and the connecting rod drives the grinding block to rotate slowly. Then, water and fertilizer are irrigated through the irrigation device. At this time, water and fertilizer flow downward, and fertilizer particles enter between the grinding block and the grinding ring through the discharge trough opened by the discharge ring. The fertilizer particles are ground by slowly rotating the grinding block in cooperation with the grinding ring, so that the fertilizer particles are completely mixed with water to form water and fertilizer. At the same time, the bottom plate can prevent the bottom of the rubber block from deforming, so that the rubber block can be stably installed in the connecting rod. At the same time, because the bottom of the rubber block will not deform, the rubber ball is more stably installed in the slot opened by the connecting rod, preventing the rubber block from displacement during the slow rotation of the connecting rod, making the storage and deployment of the stirring rod more stable. 3. In the present application, by means of the electronic valve, hose, connecting threaded pipe, connecting pipe, connecting ring, rubber ring, threaded sleeve, connecting shell, external threaded pipe, liquid dispensing tube, fixed shell, mounting sleeve, plug sleeve, liquid outlet trough, filter cloth sleeve, metal filter mesh sleeve, top cover, fixing column, threaded rod, positioning column, rubber pad, sponge sleeve, sealing cover and rubber plate, the electronic valve can be opened to allow the water and fertilizer to flow out of the mixing box, and then the water and fertilizer flow into the connecting shell through the hose connecting threaded pipe, connecting pipe, connecting ring and threaded sleeve. As the water and fertilizer in the connecting shell gradually increases, the water and fertilizer flow into the subsequent connecting shells until the water and fertilizer flows into the last connecting shell. At this time, the water and fertilizer are prevented from flowing out by the sealing cover and rubber plate. As the water and fertilizer in the connecting shell gradually increases, the water and fertilizer are stored in the connecting shell. The liquid level gradually rises, and then the water and fertilizer enter the fixed shell through the liquid distribution pipe, and the water and fertilizer gradually penetrate into the metal filter sleeve and the filter cloth sleeve through the sponge sleeve in the fixed shell, and then the water and fertilizer flow into the soil through the liquid outlet groove opened by the plug sleeve, so as to achieve uniform fertilization of water and fertilizer. After long-term use, the top cover can be directly removed, and the top cover drives the positioning column to move upward through the fixed column and the threaded rod to remove the sponge sleeve. At this time, the positioning column is rotated to remove the positioning column and the threaded rod from the bottom of the fixed column, and then the sponge sleeve can be replaced. After replacement, the sponge sleeve is installed on the outside of the positioning column, and then the positioning column is installed on the bottom of the fixed column through the threaded rod. At this time, the rubber pad is clamped by the fixed column and the positioning column, which is convenient for maintenance of the sponge sleeve to prevent blockage.

Through this arrangement, the electronic valve 81 can be opened to allow water and fertilizer to flow out of the mixing box 1.Then, the water and fertilizer flow into the connecting shell 851 through the hose 82 connected to the threaded pipe 83, the connecting pipe 841, the connecting ring 842 and the threaded sleeve 844. As the water and fertilizer in the connecting shell 851 gradually increases, the water and fertilizer flow into the subsequent connecting shells 851 until the water and fertilizer flow into the last connecting shell 851. At this time, the water and fertilizer are prevented from flowing out by the sealing cover 87 and the rubber plate 88. As the water and fertilizer in the connecting shell 851 gradually increases, the liquid level of the water and fertilizer in the connecting shell 851 gradually rises. Then, the water and fertilizer enter the fixed shell 854 through the liquid distribution pipe 853. The water and fertilizer gradually penetrate into the metal filter mesh sleeve 859 and the filter cloth sleeve 858 through the sponge sleeve 866 in the fixed shell 854.

After replacement, the sponge cover 866 is installed on the outside of the positioning column 864. The positioning column 864 is then installed on the bottom of the fixing column 862 through the threaded rod 863. At this time, the rubber pad 865 is clamped by the fixing column 862 and the positioning column 864, which facilitates maintenance of the sponge cover 866 and prevents clogging.

[0020] Working process: When using this water and fertilizer irrigation equipment, first place the mixing box 1 at a suitable position on one side of the cotton field. At this time, support the mixing box 1 through the support rod 5, then connect the external power supply and external controller to the mixing box 1, bend and lay the hose 82, and then thread one end of the threaded sleeve 844 to the outside of the connecting threaded pipe 83 until the threaded sleeve 844 pushes the rubber ring 843 fixed on the connecting ring 842 to fit tightly with the connecting threaded pipe 83, and then select a suitable position to insert one end of the sleeve 856 into the suitable position of the cotton field through the conical setting. At this time, the soil in the field is blocked by the filter cloth sleeve 858 to prevent the soil from entering the sleeve 856. At the same time, the metal filter mesh sleeve 859 can filter The cloth sleeve 858 is supported to prevent the filter cloth sleeve 858 from being deformed, and further prevents soil from entering the plug sleeve 856. After the plug sleeve 856 is installed, the external threaded tube 852 provided at one end of the connecting shell 851 and the rubber ring 843 at one end of the connecting tube 841 fit together, and then the threaded sleeve 844 is rotated to make the threaded sleeve 844 and the external threaded tube 852 threadedly connected. At this time, the rubber ring 843 and the external threaded tube 852 fit tightly together. Then, several connecting shells 851 and fixed shells 854 are installed in the cotton field in the same way as above, and the sealing cover 87 is threadedly connected to the outer side of the external threaded tube 852 at one end of the last connecting shell 851. At this time, the sealing cover 87 pushes the rubber plate 88 to fit tightly with the external threaded tube 852. Add an appropriate amount of clean water through the feed pipe 3, then put in an appropriate amount of fertilizer particles, install the fixed cover 4 on the top of the feed pipe 3, and then start the servo motor 61 through the external controller. The servo motor 61 drives the connecting rod 621 to rotate through the output shaft, and the connecting rod 621 drives the grinding block 63 to rotate at the same time. At this time, the stirring rod 624 rotates under the centrifugal force of the rotation of the connecting rod 621, and one end of the stirring rod 624 gradually leaves the placement groove 622 opened by the connecting rod 621. At this time, the other end of the stirring rod 624 pushes the rubber block 625 to deform under the action of the deformation groove 626 opened. As the stirring rod 624 rotates, the stirring rod 624 stirs the water to fully mix the water and the fertilizer particles. During the mixing process, the bottom plate 627 is used to prevent the bottom of the rubber block 625 from being deformed, so that the rubber ball 628 is installed more stably in the slot 629 opened by the connecting rod 621, thereby making the installation of the rubber block 625 more stable. After the mixing is completed, the speed of the servo motor 61 is adjusted by the external controller. As the speed of the servo motor 61 decreases, the speed of the connecting rod 621 and the grinding block 63 decreases. At this time, the centrifugal force decreases, and the rubber block 625 is reset under the action of its own elastic force. At the same time, the rubber block 625 pushes the stirring rod 624 back to the placement slot 622 opened by the connecting rod 621. Then, the electronic valve 81 is opened by the external controller, and the water and fertilizer flow into the hose 82 through the electronic valve 81. At the same time, the water and fertilizer drive the undissolved fertilizer particles to move downward.The fertilizer particles gradually move between the grinding block 63 and the grinding ring 65 through the discharge trough 66 opened by the discharge ring 64. The fertilizer particles are crushed by the rotating grinding block 63, so that the fertilizer particles are fully mixed with water to form water fertilizer. Then the water fertilizer enters the connecting shell 851 through the hose 82, the connecting threaded pipe 83, the rubber ring 843, the connecting ring 842, the connecting pipe 841 and the external threaded pipe 852. As the water fertilizer in the connecting shell 851 increases, the water fertilizer overflows and flows out through the external threaded pipe 852 on the other side. Then the water fertilizer flow The water and fertilizer are then poured into the next connecting shell 851. As the water and fertilizer in the connecting shells 851 gradually increase, the liquid level of the water and fertilizer gradually rises. When the water and fertilizer liquid level exceeds the bottom of the inner wall of the liquid distribution pipe 853, the water and fertilizer enter the fixed shell 854 through the liquid distribution pipe 853, and then flow into the sponge sleeve 866. The water and fertilizer diffuse downward through the sponge sleeve 866, and then flow out through the metal filter sleeve 859 and the filter cloth sleeve 858. Finally, the water and fertilizer flow into the soil through the liquid outlet 857 opened by the plug sleeve 856, thereby achieving the purpose of cotton cultivation.
