A stirring mechanism is provided on one side of the mixing box, and a folding mechanism is provided on the other side of the mixing box. A spraying mechanism is provided on one side of the folding mechanism. By placing the device on the agricultural machinery carrier, water and medicine are poured into the storage box, and the stirring rod and the stirring blade are pulled and driven to rotate to stir the medicine and water.

Swinging, by starting the driving motor 321 to drive the arc rod 322 to rotate inside the concave plate 312, one end of the arc rod 322 rotates at one end of the connecting plate 315, thereby driving the connecting plate 315 and the rotating block 314 to rotate synchronously, and because the other end of the connecting plate 315 rotates on the surface of the rotating block 314, the rotating block 314 and the rotating rod 313 rotate reciprocatingly, so that the connecting rod 316, the lifting box 41 and the spraying pipe 317 swing back and forth synchronously, and driven by the driving motor 321, the spraying pipe 317 and the spraying head swing back and forth, so that the spraying range of the agricultural liquid is larger and the liquid spraying is more uniform.

[0028] Embodiment 2

[0029] The main difference from the first embodiment is:

[0030] A mechanical spraying device for agricultural machinery engineering, wherein the lifting assembly 4 includes a lifting box 41 installed at one end of a connecting rod 316, a slide groove is provided on the right side of the lifting box 41, a moving rod slides on the inner surface of the slide groove, a symmetrical limit rod 42 is fixedly connected to the inside of the lifting box 41, a lifting motor 43 is fixedly connected to the bottom of the inner cavity of the lifting box 41, and the lifting motor 43 is a three-phase asynchronous motor. The lifting motor 43 is connected to a battery through an electric wire, and one end of the output shaft of the lifting motor 43 is fixedly connected to a control gear 44 through a coupling The surface of the control gear 44 is controlled by a transmission assembly 45 so that the sliding plate 46 slides on the surface of the limiting rod 42. The limiting rod 42 is used to limit the sliding plate 46. The right side of the sliding plate 46 is fixedly connected to the surface of the spray pipe 317 through a moving rod. The transmission assembly 45 includes a transmission plate 451 installed on the surface of the limiting rod 42. The transmission plate 451 is internally rotatably connected to a transmission block 452. The transmission block 452 is internally threadedly connected to a screw rod 453. A slot is provided at the bottom of the lifting box 41 to facilitate the upward and downward movement of the screw rod 453. The top of the screw rod 453 is fixedly connected to the bottom of the sliding plate 46, the surface of the transmission block 452 is meshed with the surface of the control gear 44 through the tooth block, and a liquid pump 6 is installed on the right side of the top of the bottom plate 1.

The top of the liquid pump 6 is fixedly connected to the bottom of the spray pipe 317 through a hose 7. The control gear 44 is driven to rotate by starting the lifting motor 43. The rotation of the control gear 44 causes the transmission block 452 to rotate inside the transmission plate 451, so that the screw rod 453, the sliding plate 46, the moving rod and the spray pipe 317 slide synchronously, and the sliding plate 46 slides on the surface of the limit rod 42 to adjust the height of the spray pipe 317 and the spray head.

[0031] During operation, first, the lifting motor 43 is started to drive the control gear 44 to rotate. The rotation of the control gear 44 causes the transmission block 452 to rotate inside the transmission plate 451, so that the screw rod 453, the sliding plate 46, the moving rod and the spraying pipe 317 slide synchronously. The sliding plate 46 slides on the surface of the limit rod 42 to adjust the height of the spraying pipe 317 and the spraying head. Then, the liquid extraction pump 6 is started to extract the liquid inside the medicine storage box 2, and sprays it through the spraying pipe 317 and the spraying head. Finally, the driving motor 321 is started to drive the arc rod 322 to rotate inside the concave plate 312. One end of the arc rod 322 is on the connecting plate 315. One end rotates, thereby driving the connecting plate 315 and the rotating block 314 to rotate synchronously, and because the other end of the connecting plate 315 rotates on the surface of the rotating block 314, the rotating block 314 and the rotating rod 313 rotate back and forth, so that the connecting rod 316, the lifting box 41 and the spraying pipe 317 swing back and forth synchronously, so that the agricultural liquid is sprayed more evenly. When the arc rod 322 rotates 45° clockwise, one end of the connecting plate 315 rotates counterclockwise at one end of the arc rod 322, and the other end of the connecting plate 315 rotates counterclockwise on the surface of the rotating block 314. At this time, the rotating block 314 and the rotating rod 313 rotate clockwise.
