Since the telescopic pipe 12 has the properties of compression and stretching, the spray head 11 will not be limited by the length of the telescopic pipe 12 when adjusting the position of use.

[0025] A tank cover 13 is movably connected to the upper end of the tank body 1 above the rotating rod 4, a liquid discharge pipe 14 is fixedly installed at the right side of the tank body 1, a connecting pipe 15 is fixedly connected to the lower end of the front of the tank body 1, and the end of the connecting pipe 15 away from the tank body 1 is connected to the rear end flange of the communication pipe 2, a bottom plate 16 is fixedly installed at the lower end of the tank body 1 behind the cross pipe 7, mounting plates 17 are fixedly connected to the left and right sides of the bottom plate 16, and a movable vehicle body is connected to the mounting plates 17 through bolts, and the movable vehicle body drives the movement of the spray head 11 on crops to realize fertilization.

[0026] Please refer to Figure 2 、 Figure 3 and Figure 5A rotating shaft 18 is fixedly installed on the upper end of the rotating rod 4, and the outer wall of the rotating shaft 18 is rotatably connected to the inner wall of the tank cover 13. A drive motor 19 located above the tank cover 13 is fixedly installed on the upper end of the rotating shaft 18, and the lower end of the drive motor 19 is fixedly connected to the upper end face of the tank cover 13. After the drive motor 19 is turned on, it drives the stirring rod 3 and the scraper 5 to rotate in the tank 1 through the connection of the rotating shaft 18 and the rotating rod 4. While the stirring rod 3 rotates, the fertilizer and water are mixed. The rotation of the rotating rod 4 can scrape the fertilizer hanging on the wall of the tank 1, so that the fertilizer can be fully mixed with the water. The outer wall of the drive motor 19 is clamped to the frame 20, and the frame 20 is bolted to the upper end of the tank cover 13.

[0027] Positioning rods 21 are fixedly sleeved at both ends of the outer wall of the horizontal pipe 7, and the lower end of the positioning rods 21 is fixedly connected to the upper end face of the bottom plate 16. A liquid outlet pipe 22 is fixedly installed on the back of the horizontal pipe 7, and the end of the liquid outlet pipe 22 away from the horizontal pipe 7 is connected to the front flange of the connecting pipe 2. The mixture in the tank 1 passes through the interior of the connecting pipe 15, the connecting pipe 2, the liquid outlet pipe 22, the horizontal pipe 7, the bend pipe 23, and the telescopic pipe 12 in sequence, and is then sprayed from the nozzle 11 to the crops. Furthermore, since a filter plate 6 is installed inside the connecting pipe 2, the mixture can block the particles after entering the interior of the connecting pipe 2, thus preventing the particles from clogging the nozzle 11. Several bend pipes 23 are evenly distributed on the front of the horizontal pipe 7, and the end of the bend pipe 23 away from the horizontal pipe 7 is threadedly connected to the upper end of the telescopic pipe 12.

[0028] Please see Figure 6 , Figure 7 and Figure 8 Each fixing block 8 has a first threaded rod 24 fixedly installed at its rear end, located inside the bracket 9. A groove 29 is formed on the back of the bracket 9 behind the first threaded rod 24. Through holes 30 for connecting spring clips 10 are evenly distributed on the front of the bracket 9. Utilizing the spring's rebound, the spring clip 10 is ejected from the inside of the fixing block 8 through the through holes 30 to the outside of the bracket 9, thus connecting the fixing block 8 to the bracket 9 and achieving a fixing effect. Extension rods 31 are fixedly installed on the left and right sides of the bracket 9, with the end of the extension rod 31 furthest from the bracket 9 connected to the bottom. The plate 16 is fixedly connected. The outer wall of the first threaded rod 24 is threaded with an inner threaded sleeve 25, and the outer wall of the inner threaded sleeve 25 is movably connected with the inner wall of the slide groove 29. The connection method of the first threaded rod 24 and the inner threaded sleeve 25 allows the fixing block 8 to be fixed inside the bracket 9. When the first threaded rod 24 is separated from the inner threaded sleeve 25, the fixing block 8 can be removed from the bracket 9. A baffle 26 located behind the bracket 9 is fixedly installed on the back of the inner threaded sleeve 25. A round rod 27 is fixedly connected to the side of the baffle 26 away from the inner threaded sleeve 25. A first knob 28 is fixedly installed at the end of the round rod 27 away from the baffle 26.

[0029] An upper end plate 32 is fixedly installed on the back of the can lid 13. A lifting rod 33 located behind the can body 1 is rotatably connected to the lower end of the upper end plate 32. A second threaded rod 34 is threadedly sleeved on the inner wall of the lifting rod 33. An inner ring block 35 located below the lifting rod 33 is fixedly installed at the lower end of the second threaded rod 34. Several balls 36 are rotatably connected to the outer wall of the inner ring block 35. A sleeve rod 37 is rotatably connected to the side of the balls 36 away from the inner ring block 35. Since several balls 36 are equidistantly arranged between the inner ring block 35 and the sleeve rod 37, the rotation of the balls 36 between the inner ring block 35 and the sleeve rod 37 is reduced. The friction between the sleeve rod 37 and the front end of the sleeve rod 37 are fixedly connected to the back of the tank body 1. The lower end of the inner ring block 35 is fixedly installed with a second knob 38 located below the sleeve rod 37. The second knob 38 rotates the second threaded rod 34. Due to the threaded connection between the second threaded rod 34 and the lifting rod 33, the second threaded rod 34 rotates in a circular motion while driving the lifting rod 33 to rotate at the lower end of the upper end plate 32. While the lifting rod 33 rotates, it can also achieve its own lifting motion. While the lifting rod 33 moves, the tank cover 13 is closed or separated from the tank body 1 through the connection of the upper end plate 32.

[0030] Working principle: In use, firstly, add fertilizer and water for crop fertilization into the tank 1. Then, rotate the second threaded rod 34 via the second knob 38. Due to the threaded connection between the second threaded rod 34 and the lifting rod 33, the rotation of the second threaded rod 34 simultaneously drives the lifting rod 33 to rotate at the lower end of the upper end plate 32. The lifting rod 33 also moves up and down simultaneously. While the lifting rod 33 is moving, the tank lid 13 is placed on the tank 1 via the upper end plate 32. Simultaneously, the second knob 38 rotates... The inner ring block 35 rotates within the sleeve rod 37. Since several balls 36 are equidistantly arranged between the inner ring block 35 and the sleeve rod 37, the rotation of the balls 36 between the inner ring block 35 and the sleeve rod 37 reduces the frictional force between them. Then, the power to the drive motor 19 is turned on. After the drive motor 19 is turned on, it drives the stirring rod 3 and the scraper 5 to rotate within the tank 1 via the connection between the rotating shaft 18 and the rotating rod 4. The rotation of the stirring rod 3 simultaneously mixes the fertilizer and water, and the rotation of the rotating rod 4 scrapes off the fertilizer adhering to the walls of the tank 1. This allows the fertilizer to mix thoroughly with the water. Then, adjust the spacing between two adjacent nozzles 11 according to the actual area to be sprayed on the crop. Press the spring clip 10 to move it into the fixing block 8 until the spring clip 10 separates from the bracket 9, allowing the fixing block 8 to slide within the bracket 9. Then, using the spring's rebound, the spring clip 10 is ejected from inside the fixing block 8 through the through hole 30 to the outside of the bracket 9. This connects the spring clip 10 to the fixing block 8 and the bracket 9, achieving a fixing effect on the fixing block 8. Due to the telescopic tube 12... The nozzle 11 has compression and tension properties, so that the length of the telescopic tube 12 does not limit the position adjustment of the nozzle 11. Finally, the valve on the connecting tube 15 is opened, and the mixture in the tank 1 passes through the connecting tube 15, the connecting tube 2, the outlet tube 22, the horizontal tube 7, the bend 23, and the telescopic tube 12 in sequence before being sprayed from the nozzle 11 onto the crops. In addition, since the connecting tube 2 is equipped with a filter plate 6, the mixture can pass through the filter plate 6 after entering the connecting tube 2, which can block the particles and prevent the particles from clogging the nozzle 11.
