[0025] The spraying mechanism 2 includes a servo motor 206. The surface of the servo motor 206 is fixedly connected to the inner cavity of the support frame 3. A lead screw 207 is fixedly connected to the output end of the servo motor 206. A lifting block 208 is threadedly connected to the surface of the lead screw 207. A support plate 217 is fixedly connected to one side of the lifting block 208. A fixing slot 218 is opened in the inner cavity of the support plate 217. An elastic block 216 is engaged in the inner cavity of the fixing slot 218. A spraying seat 201 is fixedly connected to the top of the elastic block 216. A nozzle 202 is connected to the bottom of the spraying seat 201.

[0026] Reference Figure 3 and Figure 4 A fixing rod 219 is fixedly connected to the top of the support plate 217, and a fixing plate 214 is slidably connected to the surface of the fixing rod 219. One side of the fixing plate 214 is fixedly connected to the surface of the spraying seat 201. The fixing rod 219 is used to position the fixing plate 214 and prevent the fixing plate 214 from moving on the top of the support plate 217, thereby ensuring that the spraying seat 201 can be stably attached to the top of the support plate 217.

[0027] Reference Figure 4 The surface of the fixing rod 219 is threaded with a fixing ring 215. The bottom of the fixing ring 215 fits tightly with the top of the fixing plate 214. The fixing ring 215 fixes the position of the fixing plate 214, preventing the fixing plate 214 from detaching from the surface of the fixing rod 219 during use, thereby improving the fixing effect on the spraying seat 201.

[0028] Reference Figure 3A second connecting seat 212 is fixedly connected to one side of the support plate 217. A fixed shaft 211 is fixedly connected to the inner cavity of the second connecting seat 212. A reinforcing rod 203 is rotatably connected to the surface of the fixed shaft 211. A positioning rod 210 is fixedly connected to the inner cavity of the reinforcing rod 203. A first connecting seat 204 is rotatably connected to the surface of the positioning rod 210. One side of the first connecting seat 204 is fixedly connected to the surface of the spraying seat 201. A positioning ring 209 is threadedly connected to the surface of the positioning rod 210. One side of the positioning ring 209 is tightly fitted to the surface of the first connecting seat 204. The connecting seat 212 supports the position of the reinforcing rod 203. The reinforcing rod 203 supports the position of the first connecting seat 204, thereby improving the stability of the spraying seat 201 during use. The positioning rod 210 positions the reinforcing rod 203 to prevent it from detaching from the first connecting seat 204 during use. The positioning ring 209 fixes the position of the positioning rod 210, thus ensuring the positioning effect of the reinforcing rod 203 and ensuring its stable support.

[0029] Reference Figure 2 and Figure 4 The inner cavity of the lifting block 208 is provided with a movable groove 213. A sealing plate 205 is slidably connected to the inner cavity of the movable groove 213. The surface of the sealing plate 205 is fixedly connected to the inner cavity of the support frame 3. By setting the movable groove 213, the lifting block 208 can slide on the surface of the sealing plate 205, thereby sealing the inner cavity of the support frame 3, preventing foreign objects from entering the interior of the support frame 3 and affecting the normal use of the parts, and reducing the maintenance frequency of the equipment.

[0030] Reference Figure 1 and Figure 5 A positioning seat 5 is fixedly connected to the top of the base 1. A storage box 14 is placed inside the cavity of the positioning seat 5. A fixing seat 4 is fixedly connected to one side of the support frame 3. A suction pump 7 is fixedly connected to the cavity of the fixing seat 4. Both the input and output ends of the suction pump 7 are connected to hoses 8 through flanges. One end of one hose 8 is connected to the spraying seat 201, and the other end of the hose 8 is connected to the storage box 14. The positioning seat 5 can be used to position the storage box 14 and prevent it from shifting during use. The fixing seat 4 supports the suction pump 7 and ensures its stable use. The suction pump 7 can extract pesticides from the storage box 14 and deliver them through the hoses 8 to the spraying seat 201, and finally to the nozzle 202 for spraying, thus completing the spraying of tobacco leaves.

[0031] Reference Figure 5A support base 13 is fixedly connected to the top of the positioning seat 5. A support shaft 12 is fixedly connected to the inner cavity of the support base 13. A protective plate 9 is rotatably connected to the surface of the support shaft 12. A baffle 6 is fixedly connected to the bottom of the protective plate 9. A connecting groove 11 is opened in the inner cavity of the protective plate 9. A protective sleeve 10 is fixedly connected to the inner cavity of the connecting groove 11. The support base 13 fixes the position of the support shaft 12 and supports the position of the protective plate 9, allowing the protective plate 9 to rotate inside the support base 13. This protects the storage box 14 inside the positioning seat 5, preventing external objects from contacting it and ensuring the normal use of the storage box 14. The connecting groove 11 allows the hose 8 to pass through the inside of the protective plate 9 and communicate with the storage box 14. The protective sleeve 10 protects the surface of the hose 8, preventing the hose 8 from being in contact with the inner wall of the connecting groove 11 for a long time, which could cause surface damage and leakage.

[0032] Working principle: When the spraying base 201 needs to be disassembled, the servo motor 206 is started by an external power supply. The servo motor 206 drives the lead screw 207 to rotate. The rotation of the lead screw 207 drives the lifting block 208 to move. The movement of the lifting block 208 drives the support plate 217 to move. The movement of the support plate 217 drives the spraying base 201 to move, lowering the height of the spraying base 201. When the spraying base 201 reaches the bottom of the support frame 3, the fixing ring 215 is rotated to remove it from the surface of the fixing rod 219, thus canceling the fixation of the fixing plate 214. Then, the spraying base 201 is moved upward. The movement of the spraying base 201 drives the elastic locking block 216 to move. When the elastic locking block 216 is under force, it deforms and compresses, thus removing the elastic locking block 216 from the inside of the fixing slot 218, canceling the positioning effect on the spraying base 201, and making it easy to disassemble the spraying base 201.

[0033] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
