The output end of the water pump 106 is fixedly connected to the second conveying pipe 109. One end of the second conveying pipe 109 is fixedly connected to the corrugated pipe 107. One end of the corrugated pipe 107 is fixedly connected to the connecting pipe 112. One end of the connecting pipe 112 is fixedly connected to the third conveying pipe 113 through a sealed bearing. One end of the third conveying pipe 113 is fixedly connected to the nozzle 108.
[0026] The top of the trolley 101 is provided with a rocking mechanism 2. The rocking mechanism 2 includes a mounting plate 201. One side of the mounting plate 201 is mounted on the top of the trolley 101. A fixing plate 202 is fixedly connected to the top of the mounting plate 201. Two handles 209 are fixedly connected to one side of the mounting plate 201. A second motor 203 is fixedly connected to one side of the fixing plate 202. The output end of the second motor 203 passes through the inner cavity of the fixing plate 202 and is fixedly connected to a rotating disk 204. A rotating column 206 is fixedly connected to one side of the rotating disk 204. A rocking rod 205 is movably connected to one side of the rotating column 206. One side of the inner cavity of the rocking rod 205 is fixedly connected to the surface of the third conveying pipe 113.
[0027] Reference Figure 4 A guide groove 210 is provided on one side of the rocker arm 205. The surface of the rotating column 206 is movably connected to the inner cavity of the guide groove 210. The guide groove 210 allows the rotating column 206 to move inside the rocker arm 205, guides the movement of the rotating column 206, and prevents the rotating column 206 from deviating during operation.
[0028] Reference Figure 4 One side of the inner cavity of the rocker arm 205 is rotatably connected to the fixed post 207. One end of the fixed post 207 is fixedly connected to the other side of the fixed plate 202, and the other end of the fixed post 207 is fixedly connected to the limit ring 208. One side of the limit ring 208 is movably connected to one side of the rocker arm 205. By setting the limit ring 208, the rotation of the rocker arm 205 can be limited, so as to prevent the rocker arm 205 from detaching from the surface of the fixed post 207 during the rotation.
[0029] Reference Figure 5 An adjustment mechanism 3 is provided on one side of the inner cavity of the trolley 101. The adjustment mechanism 3 includes a fixed box 301. The surface of the fixed box 301 is fixedly connected to one side of the inner cavity of the trolley 101. An adjustment plate 306 is movably connected to the inner cavity of the fixed box 301. The top of the adjustment plate 306 is fixedly connected to the bottom of the mounting plate 201. A fixed frame 302 is fixedly connected to one side of the fixed box 301. A movable column 303 is movably connected to the inner cavity of the fixed frame 302. A fixed ring 310 is fixedly connected to one end of the movable column 303. A movable block 304 is fixedly connected to the other end of the movable column 303. The movable block 304 increases the contact area between the operator and the movable column 303, making it more convenient for the operator to pull the movable column 303. The fixed frame 302 fixes the position of the mounting plate 201 after height adjustment, preventing the mounting plate 201 from shaking after adjustment.
[0030] Reference Figure 5 A rotary spring 305 is slidably sleeved on the surface of the movable column 303. One end of the rotary spring 305 is fixedly connected to one side of the fixed ring 310, and the other end of the rotary spring 305 is fixedly connected to one side of the fixed frame 302. With the setting of the rotary spring 305, when the movable column 303 moves, the rotary spring 305 is stretched and deformed. After the rotary spring 305 loses its stretching force, it can drive the movable column 303 to reset.
[0031] Reference Figure 6 The adjusting plate 306 has a fixing groove 307 on one side. There are four fixing grooves 307. One end of the moving column 303 is fixedly inserted into the inside of the fixing groove 307. The fixing groove 307 allows the moving column 303 to move inside the adjusting plate 306. At the same time, it fixes the position of the fixing groove 307 after adjustment, so as to prevent the fixing groove 307 from shifting under the action of external force.
[0032] Reference Figure 6 A limiting groove 308 is provided on one side of the inner cavity of the fixed box 301. There are two limiting grooves 308. A limiting block 309 is movably connected inside the limiting groove 308. One end of the limiting block 309 is fixedly connected to the surface of the adjusting plate 306. By setting the limiting groove 308, the movement of the adjusting plate 306 can be limited, so as to prevent the adjusting plate 306 from detaching from the inside of the fixed box 301 during the movement.
[0033] Working principle: The operator pulls the handle 209 to move the mounting plate 201. The mounting plate 201 moves the adjusting plate 306 inside the fixed box 301. The adjusting plate 306 moves the limiting block 309 inside the limiting groove 308. The limiting block 309 limits the movement of the adjusting plate 306. At the same time, the movement of the mounting plate 201 stretches the bellows 107. When the mounting plate 201 reaches the appropriate height, the operator pulls the moving block 304 to move the moving column 303. The movement of the moving column 303 causes the rotating spring 305 to deform. After the rotating spring 305 loses its tension, it can drive the moving column 303 to reset, so that the moving column 303 fits into the fixed groove 307, fixing the height adjusted by the adjusting plate 306. Then, the operator pours pesticides and water into the storage tank 102 through the inlet pipe 104. Then, the first motor 10... The operation of motor 3 drives the rotating rod 110 to rotate, which in turn drives the stirring rod 111 to mix the pesticide and water evenly. Then, through the operation of the first delivery pipe 105, the mixture enters the water pump 106. The output of the water pump 106 delivers the mixed liquid to the corrugated pipe 107 and the connecting pipe 112. Through the connecting pipe 112, the mixture enters the third delivery pipe 113 and then the nozzle 108. The operation of the second motor 203 drives the rotating disk 204 to rotate, which in turn drives the rotating column 206 to move inside the guide groove 210. One side of the rotating column 206 rotates around the surface of the fixed column 207. The rocking rod 205 drives the third delivery pipe 113 to rock. At this time, the sealing bearing prevents the liquid inside the third delivery pipe 113 from leaking. The third delivery pipe 113 drives the nozzle 108 to rock and spray.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
